Each round's fix moved the same defect rather than closing it: round 5's reviewer defeated a regex, round 6 replaced it with an AST walk, and round 7 showed the walk's gate is still an allowlist of variable names (ROW_NAMES, 11 entries). Measured: of 829 mapping constructs in the 18 readers, 59 are classified as row-cell sources and 35 of those are the bare name 'header'; FOUR LIVE header resolutions (viewer/parsers.py:1827, bin/perry-task:6029 and :6200, bin/perry-tasks:925) can be reverted to the exact historical defect with the whole 2793-test suite green, and parsers.py:1827 silently drops a KR when reverted. In the other direction the check now reports CORRECT code — 6 of 8 legitimate shapes flagged, including the exact latent risk round 5 recorded. Blind to four of the tree's own header resolutions AND loud about a keyword tokenizer: both failure modes the spec names, in one artefact. THE CHOICE. (A) Round 8, same shape — widen the source-expression recognition. The record says this is the fourth time that has moved the defect. (B) Invert the burden: flag EVERY case-folding map in a reader, and require the ~30 legitimate value normalizers to carry a one-line opt-out marker. Correct code declares itself once; anything new is caught by default. Cost: touching 30 live sites and a new convention. (C) RECOMMENDED — make it structurally impossible: one header_index() function becomes the only thing allowed to fold a header, and the guard becomes 'nothing outside it calls squash on a row', which is a one-symbol surface instead of a shape.

I caused three of the five, and every one is the same shape: two situations answered as one, one step to the left of the last. Round 1 collapsed four None-returns. Round 2 collapsed 'no-track-record' into unusable and hard-blocked three of this repo's own fixtures. Round 3 collapsed the two default cases. Round 4 filtered on the NAME 'main' instead of on whether the table DECLARED it. Round 5 compares on names over records, so a record that CONTRADICTS a declared row counts as carrying it. THE DECISION, and the reviewer states it cleanly: two principles are each defensible applied once, and round 5 applies one to the synthesised main and the other to the recorded main. (A) 'A declared row the register contradicts is drift' — then a table declaring queue/4/3d beside a store recording project must WARN, and perry-lint already computes exactly that. (B) 'The store is truth and the table is a stale projection' — then the trackless case must be SILENT too, because the register answered there as well. Pick one and it applies everywhere; the current code cannot be right because it holds both. SECOND, SEPARATE DECISION — the refusal WIDTH, and it is urgent because I made it worse: I widened the write refusal from source=store-default to source=store, and the reviewer measured three ordinary hand-edit workflows now hard-blocked that wrote at 45a355d AND at round 4. On the third — derive the store from a two-track table, then hand-swap one row — 'perry-config write --from-file', the ONLY command both refusal messages name, exits 1. The block cannot be cleared by the documented remedy. Options: revert to round 4's narrower width; make it a warning rather than a refusal; or fix perry-config so the remedy works. THIRD: the perry-goals half of the guard is a tautology — deleting it leaves the full 2875-test suite at exactly the baseline, which is the same defect TestTheGoalsLaneRefusesToo's own docstring records against round 2. My recommendation: (A) for the principle, because perry-lint already owns that rule and the root cause across three rounds has been re-deriving it differently; plus revert the refusal width to round 4's until perry-config's remedy is fixed. All of this is on an UNMERGED branch, so nothing is harmed in production.

I said I would escalate rather than attempt a fourth, so here it is. ROUND 3's FAIL: the gate is read at a moment the command controls. cmd_add's queue-mode branch calls ensure_section('Intake') BEFORE commit() asks the gate, so the gate sees a freshly created, readable, EMPTY table, answers yes, derives [] and writes zero bytes. Measured: a 291-byte 3-record intake.jsonl goes to 0 on 'perry-task add --track ops' with rc 0, byte-identical on 45a355d, and perry-lint reports '0 row(s) drifted'. It is round 1's blocking finding word for word — round 2 closed it for the project-mode track and never asked the queue-mode track, which is the mode ## Intake exists for. Three more doors of the same shape: intake 3->1, ask 3->1, risk-add 3->1, all rc 0, all preserved on base. THE DECISION. (A) Evaluate the gate against the board AS IT WAS AT COMMAND ENTRY, not after the command mutated it — snapshot the shape before any board write. Principled and small, but it is the fourth 'move the question' fix on this row and the first three all looked principled too. (B) RECOMMENDED — make it structurally impossible: an ordinary write may never SHRINK a canonical store. Only an explicit removal command (purge, resolve-intake, intake-sweep) may reduce the record count, and any derivation that would produce fewer records than the store holds is a refusal, not a write. That is one invariant covering every door found in three rounds — the command name, the non-unique tuple, the four section shapes, and the ensure_section ordering — instead of a fourth predicate. (C) Revert TASK-203 entirely and reconsider the row. It has introduced a store-truncation regression in all three rounds; before it, intake.jsonl did not exist and could not be wrong. That is a real 'should we do this at all' question and it deserves an answer, not an assumption. (D) Narrow the scope to the risks register only, which is the one that already existed, and defer intake/asks. NOTE THIS AFFECTS THE PHASE: TASK-203 is the ONLY row under P003-O1-KR1, and DoD Must-Have 2 names intake.jsonl and asks.jsonl explicitly, so (C) or (D) means the phase misses that Must-Have deliberately rather than by accident. Also filed from this round: my third shape test is VACUOUS (the legend table lands under ## Top risks because ensure_section anchors ## Intake before ## P0, so the foreign shape has no test on any register); the uniqueness test cannot distinguish uniqueness from adjacency; load_register_records lets a JSONDecodeError escape as an uncaught traceback where every other failure in that file is a Refused.

In the other direction the check now reports CORRECT code — 6 of 8 legitimate shapes flagged, including the exact latent risk round 5 recorded. Blind to four of the tree's own header resolutions AND loud about a keyword tokenizer: both failure modes the spec names, in one artefact. THE CHOICE. (A) Round 8, same shape — widen the source-expression recognition. The record says this is the fourth time that has moved the defect. (B) Invert the burden: flag EVERY case-folding map in a reader, and require the ~30 legitimate value normalizers to carry a one-line opt-out marker. Correct code declares itself once; anything new is caught by default. Cost: touching 30 live sites and a new convention.

I caused three of the five, and every one is the same shape: two situations answered as one, one step to the left of the last. Round 1 collapsed four None-returns. Round 2 collapsed 'no-track-record' into unusable and hard-blocked three of this repo's own fixtures. Round 3 collapsed the two default cases. Round 4 filtered on the NAME 'main' instead of on whether the table DECLARED it. Round 5 compares on names over records, so a record that CONTRADICTS a declared row counts as carrying it. THE DECISION, and the reviewer states it cleanly: two principles are each defensible applied once, and round 5 applies one to the synthesised main and the other to the recorded main. (A) 'A declared row the register contradicts is drift' — then a table declaring queue/4/3d beside a store recording project must WARN, and perry-lint already computes exactly that. (B) 'The store is truth and the table is a stale projection' — then the trackless case must be SILENT too, because the register answered there as well. Pick one and it applies everywhere; the current code cannot be right because it holds both. SECOND, SEPARATE DECISION — the refusal WIDTH, and it is urgent because I made it worse: I widened the write refusal from source=store-default to source=store, and the reviewer measured three ordinary hand-edit workflows now hard-blocked that wrote at 45a355d AND at round 4. On the third — derive the store from a two-track table, then hand-swap one row — 'perry-config write --from-file', the ONLY command both refusal messages name, exits 1. The block cannot be cleared by the documented remedy. Options: revert to round 4's narrower width; make it a warning rather than a refusal; or fix perry-config so the remedy works. THIRD: the perry-goals half of the guard is a tautology — deleting it leaves the full 2875-test suite at exactly the baseline, which is the same defect TestTheGoalsLaneRefusesToo's own docstring records against round 2. My recommendation: (A) for the principle, because perry-lint already owns that rule and the root cause across three rounds has been re-deriving it differently; plus revert the refusal width to round 4's until perry-config's remedy is fixed.

I said I would escalate rather than attempt a fourth, so here it is. ROUND 3's FAIL: the gate is read at a moment the command controls. cmd_add's queue-mode branch calls ensure_section('Intake') BEFORE commit() asks the gate, so the gate sees a freshly created, readable, EMPTY table, answers yes, derives [] and writes zero bytes. Measured: a 291-byte 3-record intake.jsonl goes to 0 on 'perry-task add --track ops' with rc 0, byte-identical on 45a355d, and perry-lint reports '0 row(s) drifted'. It is round 1's blocking finding word for word — round 2 closed it for the project-mode track and never asked the queue-mode track, which is the mode ## Intake exists for. Three more doors of the same shape: intake 3->1, ask 3->1, risk-add 3->1, all rc 0, all preserved on base. THE DECISION. (A) Evaluate the gate against the board AS IT WAS AT COMMAND ENTRY, not after the command mutated it — snapshot the shape before any board write. Principled and small, but it is the fourth 'move the question' fix on this row and the first three all looked principled too. (B) RECOMMENDED — make it structurally impossible: an ordinary write may never SHRINK a canonical store. Only an explicit removal command (purge, resolve-intake, intake-sweep) may reduce the record count, and any derivation that would produce fewer records than the store holds is a refusal, not a write. That is one invariant covering every door found in three rounds — the command name, the non-unique tuple, the four section shapes, and the ensure_section ordering — instead of a fourth predicate. (C) Revert TASK-203 entirely and reconsider the row. It has introduced a store-truncation regression in all three rounds; before it, intake.jsonl did not exist and could not be wrong. That is a real 'should we do this at all' question and it deserves an answer, not an assumption. (D) Narrow the scope to the risks register only, which is the one that already existed, and defer intake/asks. NOTE THIS AFFECTS THE PHASE: TASK-203 is the ONLY row under P003-O1-KR1, and DoD Must-Have 2 names intake.jsonl and asks.jsonl explicitly, so (C) or (D) means the phase misses that Must-Have deliberately rather than by accident.

Do NOT snapshot the gate at command entry; that was option A and it is the fourth 'move the question' fix. REGRESSION TEST FIRST, red before the fix: 24 records to 0 with ## Intake absent. Also fix in the same round: the third shape test is VACUOUS (the legend lands under ## Top risks because ensure_section anchors ## Intake before ## P0, so the foreign shape has NO test on any register); the uniqueness test cannot distinguish uniqueness from adjacency; load_register_records lets JSONDecodeError escape as a bare traceback where every other failure in that file is a Refused; readable_as_register's 'section' parameter is dead.

Worse, before TASK-235 the behaviour was NON-DETERMINISTIC: on main an unrelated write re-rendered the index and the next mint reissued anyway. THE STAKE: an ADR id is an address. ADR-007 is cited by name in ADR-010, in DESIGN-013, in three task rows and in this project's own commit messages. If 011 can name two different decisions, every one of those citations becomes ambiguous the moment an ADR is deleted and a new one minted. This did not matter while nobody deleted ADRs; TASK-235 is the row that made deletion ordinary. THE OPTIONS. (a) RECOMMENDED — perry-decide writes events like every other writer, and an id is retired the way perry-task retires one. This is the answer that makes the two tools agree rather than documenting why they differ, and DESIGN-004's whole posture is that every write goes through a tool and leaves a trace. Cost: perry-decide gains an event surface it does not have today. (b) Refuse the delete instead: an ADR file may not be removed, only superseded — which is arguably what a decision record SHOULD mean, since ADR-005 and ADR-007 are cited as history and history is not deleted. Cheaper, and it may be more correct in principle. (c) Accept reissue, and document that an ADR id is a slot rather than an address. Honest but it silently breaks every existing citation. (d) Leave it declared as it is now — the TASK-235 agent pinned the disagreement with a named test rather than resolving it silently, so nothing is hidden and the row can close.

(1) THE CORPUS WAS PRUNED: '30 of 30' is measured on a corpus described as a superset of round 7's and is neither — round 7 Finding 2 names 'a scalar header-row test' and 'P23-P25, round 4's _is_python hole', neither is in it, and the labels P23-P25 were RE-USED for three different shapes so the omission is invisible in the numbering. Re-derived and planted with a control: all five variants escape BOTH nets, control caught. Honest fraction 30 of at least 33. The scalar class is structural — neither net inspects anything but a mapping construct, so read_conformance's historically damaging shape is outside both BY CONSTRUCTION, with a live instance at viewer/parsers.py:2582. (2) THE DEFEATED SHAPE NET WAS KEPT AND STILL GATES THE SUITE: appending an ordinary multi-value-cell normalizer to a real reader turns tests/run RED, and one failing test is named test_value_normalizers_are_not_flagged. NET 1 ALONE IS CLEAN ON ALL EIGHT SHAPES — a defence the author never makes. Round 9 deletes net 2. Also: ROW_NAMES survives and IS load-bearing (emptied, the harness drops to 22 of 30), plus a second name allowlist at header_rule.py:357-360, so round 8's 'dropped ROW_NAMES rather than extending it' is false; and perry-diagnose.md_table is watched by the closing test while contributing ZERO folds because it pre-strips decoration itself. (3) THE RETRACTION IS INCOMPLETE: 68e63cf added 6.9 but left 5's 'the runners disagree by 3' standing, and 6.9's own closing line is untrue of it; 2 says 67 call sites where its table says 58."} +{"ts": "2026-08-30T00:33:59+08:00", "event": "next", "id": "TASK-203", "title": "an ordinary write does not update its store, for either the risks or the intake register — one row, both registers", "track": "main", "actor": "Ran Jiao", "from": "ROUND 4 DELIVERED, REVIEW NOT DONE — the reviewer was terminated by the session rate limit before it read anything.

Round 5 dispatched with a fix that stays INSIDE option B. THE INVARIANT ITSELF IS SOUND — the reviewer states refuse_to_shrink closes all four known doors and could not be broken from inside. THE FIFTH DOOR IS THE EXEMPTION: SHRINK_ALLOWED grants its licence BY COMMAND NAME AND WITHOUT A BOUND, so a listed command may shrink a store by any amount including a shrink it did not perform — and resolve-intake, which round 4's own finding established removes NO record at all, therefore holds an unbounded licence to destroy the whole store. Reproduced on this repository's own intake data: 11781 bytes / 28 records, 24 rows tidied off the board by hand (the /pmo triage state), then 'resolve-intake 1 --outcome dropped' returns rc 0 and leaves 1420 bytes / 4 records, with perry-lint reporting '0 error(s) · intake store: 4 record(s), 0 row(s) drifted'. Same signature as the merge-hold reproduction. intake-sweep has the same hole: reported sweeping 1 row, took a store 4 to 1. WHY THE ROUND'S OWN TEST COULD NOT CATCH IT: mutation MR (drop only resolve-intake from the allowlist) reddens two tests, BOTH assertions about the constant, because test_resolve_intake_is_not_blocked_and_does_not_in_fact_shrink runs on a CLEAN BOARD where no shrink is possible.

THE CORRECTION: perry-decide's justification for dropping the ADR-004 gate closed with 'only the index write was ever gated', which is false — on a real main snapshot at ee0b36a with enforce and nothing declared, perry-decide new returns rc=1, refuses, and writes NO ADR body, while the branch returns rc=0 and writes ADR-001.

WORTH KEEPING FROM THIS ROUND: the agent's first check appeared to REFUTE the reviewer, and that check was the broken one — it ran main's perry-decide with the BRANCH's PERRY_HOME, so it loaded the branch schema, found no files[id=decisions] and returned 'absent'.

Deleting the phase check left the entire suite's failure set BYTE-FOR-BYTE IDENTICAL. Fixed at 09dcdff with two tests supplying P002-O1-KR1 inside 001-linkage.md with the objective kept at O1, so only the phase half can fire. (2) THE ROW COMMITTED ITS OWN FAILURE MODE: the inherited RESULT claims 'Linked overall KR' was not dropped with the table and its companion says it WAS carried verbatim; both are false for phase 001, where all eight linked: values were copied from the RETRO SCORE TABLE's Measured column. Eight edges to the overall OKR deleted and prose put in their place — P001-O1-KR1's edge to KR-O1.1 became a sentence about parse_tracks returning [('main','project')]. 16 of 24 cells survived at 8abd30d, 24 of 24 after 3784059.

Round 5 dispatched with a fix that stays INSIDE option B. THE INVARIANT ITSELF IS SOUND — the reviewer states refuse_to_shrink closes all four known doors and could not be broken from inside. THE FIFTH DOOR IS THE EXEMPTION: SHRINK_ALLOWED grants its licence BY COMMAND NAME AND WITHOUT A BOUND, so a listed command may shrink a store by any amount including a shrink it did not perform — and resolve-intake, which round 4's own finding established removes NO record at all, therefore holds an unbounded licence to destroy the whole store. Reproduced on this repository's own intake data: 11781 bytes / 28 records, 24 rows tidied off the board by hand (the /pmo triage state), then 'resolve-intake 1 --outcome dropped' returns rc 0 and leaves 1420 bytes / 4 records, with perry-lint reporting '0 error(s) · intake store: 4 record(s), 0 row(s) drifted'. Same signature as the merge-hold reproduction. intake-sweep has the same hole: reported sweeping 1 row, took a store 4 to 1. WHY THE ROUND'S OWN TEST COULD NOT CATCH IT: mutation MR (drop only resolve-intake from the allowlist) reddens two tests, BOTH assertions about the constant, because test_resolve_intake_is_not_blocked_and_does_not_in_fact_shrink runs on a CLEAN BOARD where no shrink is possible.

The gate is 'if before - after <= declared_removal(event): return'. Still one question about two integers, not 'may this command shrink' but 'is the drop the drop the caller declared'; nothing is asked about the board, the shape, or when the gate is read, so option A stays rejected and stays unnecessary. Two design points beyond the arithmetic: refuse_to_shrink now takes the EVENT rather than the event name, so the bound is computed inside and no call site can carry the permission without the number; and declared_removal FAILS CLOSED — an unnamed command declares 0, and a listed command whose count is missing, negative, a bool or not an int declares 0 too. BOTH DOORS CLOSED, side by side on this repository's own data against a git archive of afb3a48: resolve-intake was rc 0 / 30 records to 4 / lint '0 drifted' and is now rc 1 / md5 unchanged / lint '26 drifted'; intake-sweep was rc 0 'wrote 1 row(s)' / to 3 records and is now rc 1 / md5 unchanged / lint '27 drifted'. The register still works — on an in-sync copy the whole lifecycle runs, discharge 30 to 30, sweep 30 to 29, new intake 29 to 30, lint clean. THE DECISIVE NUMBER: the previous reviewer's own mutation MR now reddens test_resolve_intake_may_not_shrink_a_store_it_removes_nothing_from, a named BEHAVIOURAL test on a drifted board, where under round 4 it reddened only two assertions about the constant. Every test in TestTheExemptionIsBounded asserts the drift as a CONTROL before any behaviour, so a clean-board version fails its own control.

THE INHERITED RESTORE POINT WAS SUBSTANTIVELY WRONG, which is why it was verified rather than merged. TWO DEFECTS FOUND IN IT, both fixed. (1) A GUARD SHIPPED WITH NOTHING HOLDING IT: f15d234 replaced linkage-kr-exists's document scan with TWO questions about the KR id — objective agreement and phase agreement — and tested only the first, because test_a_genuinely_wrong_kr_is_still_reported supplies P001-O9-KR9 whose phase is still 001 and can never reach the phase half. Deleting the phase check left the entire suite's failure set BYTE-FOR-BYTE IDENTICAL. Fixed at 09dcdff with two tests supplying P002-O1-KR1 inside 001-linkage.md with the objective kept at O1, so only the phase half can fire. (2) THE ROW COMMITTED ITS OWN FAILURE MODE: the inherited RESULT claims 'Linked overall KR' was not dropped with the table and its companion says it WAS carried verbatim; both are false for phase 001, where all eight linked: values were copied from the RETRO SCORE TABLE's Measured column. Eight edges to the overall OKR deleted and prose put in their place — P001-O1-KR1's edge to KR-O1.1 became a sentence about parse_tracks returning [('main','project')]. 16 of 24 cells survived at 8abd30d, 24 of 24 after 3784059. The new guard requires every non-empty linked to RESOLVE against perry-goals list --level overall, not shape-match, because KR-O9.9 has the right shape — and refuses to pass on zero values. (3) The inherited RESULT shipped six unsubstituted placeholders, its one real row measured at the wrong commit, '3 pre-existing failures' where it is 5, and '22 rows' where it is 24.

The branch adds no failure and removes none. Twelve mutations all reddening named tests, with a harness that ASSERTS THE TARGET IS GREEN BEFORE MUTATING — which caught a meaningless red where test_cadence.py's 'from gate import GATE_OFF' only resolves under discover, so a bare-module run reports unittest.loader._FailedTest as if the mutation had worked.

Round 9 dispatched — and it is NOT a ninth widening: two of the three fixes are DELETIONS. WHAT THE REVIEWER VERIFIED RATHER THAN ACCEPTED, and none of it is to be touched: nine mutations reproduce with md5 restores; M9's split verdict exact; the ihdr drift case round 7 measured as escaping is now caught WITH NO ALLOWLIST ENTRY; parsers.py:1833 reverted loses the KR and reddens three named tests; the docstring-grep test genuinely gone; alias-after-fold exact (the property needed is alias∘squash = alias and it holds); no site found where the list subclass changes behaviour; criterion 5 driven end-to-end through four CLIs on a 64-cell half-bolded fixture, byte-identical. header_index() is right. THE THREE FAILURES. (1) THE CORPUS WAS PRUNED: '30 of 30' is measured on a corpus described as a superset of round 7's and is neither — round 7 Finding 2 names 'a scalar header-row test' and 'P23-P25, round 4's _is_python hole', neither is in it, and the labels P23-P25 were RE-USED for three different shapes so the omission is invisible in the numbering. Re-derived and planted with a control: all five variants escape BOTH nets, control caught. Honest fraction 30 of at least 33. The scalar class is structural — neither net inspects anything but a mapping construct, so read_conformance's historically damaging shape is outside both BY CONSTRUCTION, with a live instance at viewer/parsers.py:2582. (2) THE DEFEATED SHAPE NET WAS KEPT AND STILL GATES THE SUITE: appending an ordinary multi-value-cell normalizer to a real reader turns tests/run RED, and one failing test is named test_value_normalizers_are_not_flagged. NET 1 ALONE IS CLEAN ON ALL EIGHT SHAPES — a defence the author never makes. Round 9 deletes net 2. Also: ROW_NAMES survives and IS load-bearing (emptied, the harness drops to 22 of 30), plus a second name allowlist at header_rule.py:357-360, so round 8's 'dropped ROW_NAMES rather than extending it' is false; and perry-diagnose.md_table is watched by the closing test while contributing ZERO folds because it pre-strips decoration itself. (3) THE RETRACTION IS INCOMPLETE: 68e63cf added 6.9 but left 5's 'the runners disagree by 3' standing, and 6.9's own closing line is untrue of it; 2 says 67 call sites where its table says 58.", "to": "ROUND 9 DELIVERED at b5e7be3, V4 review dispatched to a FRESH reviewer. THE SHAPE NET IS DELETED, and with it ROW_NAMES, the second name allowlist, _local_folders, FOLDING_METHODS, _string_constants and the .split('|') row inference that produced round 8's false positive. NO ALLOWLIST OF VARIABLE NAMES SURVIVES ANYWHERE — grep ROW_NAMES returns four prose lines saying it was deleted and no code; what remains is BLESSED/THE_RULE/ROW_PRODUCERS (function names, which are the design), ITERABLE_WRAPPERS (builtins), NOT_A_READER (four directories each with a reason) and inline str method names for following a value through a chain, all tabulated so they can be checked rather than believed. THE COST IS MEASURED, NOT DESCRIBED, and it is what the review turns on: DRIFT 24 of 24 caught, CLEAN 0 of 12 falsely flagged where round 8 was 1 of 8, and SECOND_RULE 0 of 41 caught. That last is the class where a reader invents a NEW folding rule that never calls squash at all, which a symbol check cannot see by construction — the reviewer is asked to rule explicitly on whether that gap is what option C ACCEPTS BY DESIGN or means the row does not close, and to argue it rather than wave it through in either direction. The author's supporting argument, also to be checked: round 8's declared false positive was on code the repository ALREADY FORBIDS, since test_row_integrity's test_no_tool_splits_a_row_on_a_raw_pipe reports a bare .split('|') anywhere in bin/ and viewer/, receiver-blind — so keeping the shape net bought nothing. TWO MORE LIVE SITES ROUND 8 LEFT, now converted and mutation-tested: bin/perry-lint:339 re-folded a key header_index had already produced, and bin/perry-task:1339 re-folded keys.raw. THE CORPUS IS REBUILT from the round 4/5/7 review prose with every entry quoting its source line and label and path uniqueness asserted AND mutation-tested — round 8's pruning was invisible because plant labels were re-used for different shapes. BOTH CARRIED FIGURES SETTLED: discover differs from tests/run by exactly 3 on three trees, the three being test_risks_store; and the call-site count is 58 on 68e63cf (round 8's table was right, its 67 was not), 59 on round 9. Ten mutations all md5-restored and all reddening a named test; R9-9 puts the pipe inference back and turns test_each_clean_shape_is_left_alone red, so criterion 4 holds as a consequence of the design.

The gate is 'if before - after <= declared_removal(event): return'. Still one question about two integers, not 'may this command shrink' but 'is the drop the drop the caller declared'; nothing is asked about the board, the shape, or when the gate is read, so option A stays rejected and stays unnecessary. Two design points beyond the arithmetic: refuse_to_shrink now takes the EVENT rather than the event name, so the bound is computed inside and no call site can carry the permission without the number; and declared_removal FAILS CLOSED — an unnamed command declares 0, and a listed command whose count is missing, negative, a bool or not an int declares 0 too. BOTH DOORS CLOSED, side by side on this repository's own data against a git archive of afb3a48: resolve-intake was rc 0 / 30 records to 4 / lint '0 drifted' and is now rc 1 / md5 unchanged / lint '26 drifted'; intake-sweep was rc 0 'wrote 1 row(s)' / to 3 records and is now rc 1 / md5 unchanged / lint '27 drifted'.

THE SHAPE NET IS DELETED, and with it ROW_NAMES, the second name allowlist, _local_folders, FOLDING_METHODS, _string_constants and the .split('|') row inference that produced round 8's false positive. NO ALLOWLIST OF VARIABLE NAMES SURVIVES ANYWHERE — grep ROW_NAMES returns four prose lines saying it was deleted and no code; what remains is BLESSED/THE_RULE/ROW_PRODUCERS (function names, which are the design), ITERABLE_WRAPPERS (builtins), NOT_A_READER (four directories each with a reason) and inline str method names for following a value through a chain, all tabulated so they can be checked rather than believed. THE COST IS MEASURED, NOT DESCRIBED, and it is what the review turns on: DRIFT 24 of 24 caught, CLEAN 0 of 12 falsely flagged where round 8 was 1 of 8, and SECOND_RULE 0 of 41 caught. That last is the class where a reader invents a NEW folding rule that never calls squash at all, which a symbol check cannot see by construction — the reviewer is asked to rule explicitly on whether that gap is what option C ACCEPTS BY DESIGN or means the row does not close, and to argue it rather than wave it through in either direction. The author's supporting argument, also to be checked: round 8's declared false positive was on code the repository ALREADY FORBIDS, since test_row_integrity's test_no_tool_splits_a_row_on_a_raw_pipe reports a bare .split('|') anywhere in bin/ and viewer/, receiver-blind — so keeping the shape net bought nothing. TWO MORE LIVE SITES ROUND 8 LEFT, now converted and mutation-tested: bin/perry-lint:339 re-folded a key header_index had already produced, and bin/perry-task:1339 re-folded keys.raw. THE CORPUS IS REBUILT from the round 4/5/7 review prose with every entry quoting its source line and label and path uniqueness asserted AND mutation-tested — round 8's pruning was invisible because plant labels were re-used for different shapes. BOTH CARRIED FIGURES SETTLED: discover differs from tests/run by exactly 3 on three trees, the three being test_risks_store; and the call-site count is 58 on 68e63cf (round 8's table was right, its 67 was not), 59 on round 9. Ten mutations all md5-restored and all reddening a named test; R9-9 puts the pipe inference back and turns test_each_clean_shape_is_left_alone red, so criterion 4 holds as a consequence of the design. Baselines: tests/run main@6c0d041 98/2882/3 and round 9 99/2895/3, same three names; discover 2882/6, 2893/6, 2895/6.", "to": "V4 ROUND 9: FAIL 2026-08-30, evidence/2026-08/TASK-050-round9-v4-review.md — but the reviewer ruled the round's CORE CORRECT and the fix is about five lines. THE QUESTION THE ROUND TURNED ON WAS RULED IN THE ROUND'S FAVOUR: 0 of 41 on SECOND_RULE is ACCEPTABLE under option C, because detecting a from-scratch fold IS source-expression recognition and failing on it would order the very thing USER-904 rejected. Measured, not argued: R9-9 reproduces exactly, so 41-of-41 and 0-of-12 cannot both be had; and the second-rule class is covered DYNAMICALLY — reverting parsers.py:1833 reddens test_every_decorated_header_cell_reached_header_index, and so did the reviewer's own value-identical alias fold at that site. THE FAIL IS THE COROLLARY: with the shape net gone the drift half carries the whole static claim, and it recognises the rule by the FUNCTION'S NAME rather than the symbol. _RowLocals resolves the two HARDER indirections the corpus plants — def fold(s): return squash(s), and fold = lambda s: squash(s) — and misses the one-liner: fold = squash, from tables import squash as fold, and import tables; fold = tables.squash all escape. This repository's own idiom is the escaping form: bin/perry-lint:250 is literally 'norm = squash', seen today only because norm happens to be in BLESSED. D06 shows the author handled import aliasing ONTO A BLESSED NAME; the case landing anywhere else is neither planted nor handled. Planted into bin/perry-tasks — the one converted reader the round itself says the watch does not drive — offenders_by_symbol goes to [], all three header modules OK, row-integrity OK, and the full suite stays at 99 modules / 2895 tests / the same three pre-existing failures. It is DRIFT, not SECOND_RULE, so the declared limit does not cover it, and it is in none of the nine limits section 6 declares. WHAT THE REVIEWER VERIFIED RATHER THAN ACCEPTED: the worktree byte-identical to its commit across 688 re-hashed blobs at start and end, so the hand restore is clean; no variable-name allowlist anywhere; header_index the only header-cell fold, by its own AST enumeration of all 39 squash/norm calls each classified by reading; both live conversions real and exact with no third site; ALL TEN mutations reproducing; the corpus rebuilt independently from rounds 4/5/7 with NO PRUNING FOUND; test_row_integrity's reach real, so the argument for deleting the shape net holds; and round 8's retraction now complete. THREE MINOR: corpus D20 says 'no shebang' but _plant prepends one unconditionally so it cannot discriminate the hole it names; Watch.__enter__'s rebinding loop survives its own deletion with all 7 tests green, contradicting its own comment; grep ROW_NAMES returns two prose lines, not the four claimed."} +{"ts": "2026-08-30T03:11:53+08:00", "event": "next", "id": "TASK-230", "title": "the full suite takes eleven minutes, and that cost has started changing behaviour", "track": "main", "actor": "Ran Jiao", "from": "DELIVERED at e685c6b, V4 review dispatched.

The fence mechanism is a naive boolean toggle flipped by ANY fence-looking line, not CommonMark's rule that a fence closes only on the same delimiter char with a run length >= the opener and nothing after. So a NESTED fence — the ordinary way markdown shows a fenced block — flips the toggle off and the row inside is read as a real declaration again. Measured on a git archive copy of 8c34973 with the branch's own perry-conform: plain fence gives undeclared/unreadable=1, while a tilde fence wrapping a backtick fence, a 4-backtick fence containing a 3-backtick line, and a backtick fence wrapping a tilde fence ALL give conformant/unreadable=0 — and the LAUNDERING comes back with them, so a legitimate declare of a different file rewrites the record to contain the decorated row as a plain canonical one. The author declared this in section 8 as 'did not verify a nested fence'; declaring it does not discharge it, because it IS the deliverable's third named shape. The reviewer sketched CommonMark's rule in a throwaway copy: ~10 lines inside the same function closes all four with the 71 tests in both touched modules still green. SECOND FINDING: 'except UnrenderableCell: canonical = None' survives its own deletion, so section 4's 'nothing I wrote can be deleted with the suite unchanged' is FALSE — and it is reachable (a U+2028 in a path cell, because read_conformance splits on \\n while line_break_at uses splitlines()'s eleven boundaries) and load-bearing, since without it perry-conform status dies with an unhandled traceback. A THIRD FRAMING the reviewer offers and neither agent found: require the row to be in the contiguous run following the '| File | ... |' header — no HEADER prose, no fence bookkeeping, and immune to this defect. Round 2 is told to evaluate it honestly against CommonMark's rule and say which it chose.

THE QUESTION THE ROUND TURNED ON WAS RULED IN THE ROUND'S FAVOUR: 0 of 41 on SECOND_RULE is ACCEPTABLE under option C, because detecting a from-scratch fold IS source-expression recognition and failing on it would order the very thing USER-904 rejected. Measured, not argued: R9-9 reproduces exactly, so 41-of-41 and 0-of-12 cannot both be had; and the second-rule class is covered DYNAMICALLY — reverting parsers.py:1833 reddens test_every_decorated_header_cell_reached_header_index, and so did the reviewer's own value-identical alias fold at that site. THE FAIL IS THE COROLLARY: with the shape net gone the drift half carries the whole static claim, and it recognises the rule by the FUNCTION'S NAME rather than the symbol. _RowLocals resolves the two HARDER indirections the corpus plants — def fold(s): return squash(s), and fold = lambda s: squash(s) — and misses the one-liner: fold = squash, from tables import squash as fold, and import tables; fold = tables.squash all escape. This repository's own idiom is the escaping form: bin/perry-lint:250 is literally 'norm = squash', seen today only because norm happens to be in BLESSED. D06 shows the author handled import aliasing ONTO A BLESSED NAME; the case landing anywhere else is neither planted nor handled. Planted into bin/perry-tasks — the one converted reader the round itself says the watch does not drive — offenders_by_symbol goes to [], all three header modules OK, row-integrity OK, and the full suite stays at 99 modules / 2895 tests / the same three pre-existing failures.

THREE MINOR: corpus D20 says 'no shebang' but _plant prepends one unconditionally so it cannot discriminate the hole it names; Watch.__enter__'s rebinding loop survives its own deletion with all 7 tests green, contradicting its own comment; grep ROW_NAMES returns two prose lines, not the four claimed.", "to": "ROUND 10 DELIVERED at 3a6222f (code tip a1ff426), tree clean, 689 blobs re-hashed with 0 mismatches.

The other is '_hdr = perry_store.intake_table(board, ops)[\"header\"]' — a row produced in ANOTHER MODULE and carried through a dict key, which a file-local walk cannot see; the same plant written with a bare squash and no alias at all escapes round 9's tree identically. Closing that statically would be interprocedural source recognition, the option the amendment rejects by name.

Reproduced on the branch tip with the markdown deleted and the store untouched, same tree, same cwd, same PERRY_HOME: perry-lint walks up and finds the project, and perry-state --json does not — it reports 'No Perry state found — run /perry for first-time setup', WHICH IS THE EXACT STRING THE AUTHOR QUOTES as the defect that justified converting resolve_state_root. The row's own fix justification still reproduces one file over. Second site with --root given so the walk is out of play: a project configured by the STORE alone reads installed:false while the same project configured by the MARKDOWN alone reads true. WHY IT BLOCKS, and it is not the reach — the reach is narrow, needing cwd != project root: the row serves a KR that COUNTS CALL SITES IN bin/, the missed sites are in the file the spec names first, and the RESULT ASSERTS COMPLETENESS rather than declaring a gap. The author's own declared grep finds both in one command. Declared gap 4 was honest and does not block; the FAIL is a DIFFERENT sentence in section 4, which says the four converted sites 'were the rest'.

All five declared gaps ruled non-blocking. TWO NUMBER CORRECTIONS: the mutation table has 28 rows, not the 27 the text claims; and the reviewer measured 100/2992/3 to 101/3031/the same 3, getting a third data-dependent test_diagnose failure the author did not, red on both sides.

THE FAIL IS THE SENTENCE AFTER IT: a dynamic cover discharges a static hole only if the round MEASURES which sites it reaches and STATES the remainder — and this round states the remainder as EMPTY when it is TWELVE. Three things, none a redesign. (1) A DICT-CARRIED HEADER ROW ESCAPES BOTH HALVES, and it is NOT interprocedural as section 7 limit 1 claims: one line in bin/perry_store.py risk_plan, which already reads header, keys = table['header'], table['keys'], gives offenders_by_symbol == [] with all three header modules OK and the full suite at the same three failures. It escapes with NO MODULE BOUNDARY AT ALL — t = {'header': split_row(line)} then [squash(c) for c in t['header']] is local dataflow in one function, resolvable by the same _RowLocals machinery that already resolves aliases. And ['header'] is this repository's own idiom. (2) THE UNCOVERED SET IS NOT EMPTY: 17 live dict-key header reads, 12 in functions the watch never reaches; WATCHED is 16 functions against 45 holding the 59 call sites. Round 11 must COMPUTE the remainder and print the number and the list, not assert it. (3) WATCHED IS A GUARD THAT SURVIVES ITS OWN DELETION — removing an entry leaves all 8 tests green, and it is the mechanism the dynamic cover depends on. Also no DRIFT corpus entry plants a dict- or attribute-carried row, which the reviewer calls the same structure as round 9's charge with a different noun.

Round 2 dispatched. THE FAIL: shape 3 of the spec's three traps is NOT closed. The fence mechanism is a naive boolean toggle flipped by ANY fence-looking line, not CommonMark's rule that a fence closes only on the same delimiter char with a run length >= the opener and nothing after. So a NESTED fence — the ordinary way markdown shows a fenced block — flips the toggle off and the row inside is read as a real declaration again. Measured on a git archive copy of 8c34973 with the branch's own perry-conform: plain fence gives undeclared/unreadable=1, while a tilde fence wrapping a backtick fence, a 4-backtick fence containing a 3-backtick line, and a backtick fence wrapping a tilde fence ALL give conformant/unreadable=0 — and the LAUNDERING comes back with them, so a legitimate declare of a different file rewrites the record to contain the decorated row as a plain canonical one. The author declared this in section 8 as 'did not verify a nested fence'; declaring it does not discharge it, because it IS the deliverable's third named shape. The reviewer sketched CommonMark's rule in a throwaway copy: ~10 lines inside the same function closes all four with the 71 tests in both touched modules still green. SECOND FINDING: 'except UnrenderableCell: canonical = None' survives its own deletion, so section 4's 'nothing I wrote can be deleted with the suite unchanged' is FALSE — and it is reachable (a U+2028 in a path cell, because read_conformance splits on \\n while line_break_at uses splitlines()'s eleven boundaries) and load-bearing, since without it perry-conform status dies with an unhandled traceback. A THIRD FRAMING the reviewer offers and neither agent found: require the row to be in the contiguous run following the '| File | ... |' header — no HEADER prose, no fence bookkeeping, and immune to this defect. Round 2 is told to evaluate it honestly against CommonMark's rule and say which it chose. EVERYTHING ELSE REPRODUCED EXACTLY, including all seven mutations, the M1-vs-M2/M3 disjointness, the controls proved able to fail, and both archive baselines; and all five declared limits were ruled, with silently deleting an unreadable row ruled ACCEPTABLE TO SHIP and the author right both not to fix it and not to file it.", "to": "V4 ROUND 2: PASS 2026-08-30; evidence/2026-08/TASK-241-round2-v4-review.md. Two RESULT corrections in flight, then merge. THE RULING THE ROUND ASKED FOR: the contiguous-run rejection STANDS, and the reviewer established it the hard way — it BUILT the framing itself from round 1's own sentence, into its own copy, never having seen the author's prototype, and probed it against its own 22-shape catalogue. The author's measurement reproduces exactly. It added two things the RESULT does not say, and both strengthen the rejection: it would have been a REGRESSION rather than merely a non-fix, because shape 15, the whole table in a plain unnested fence, is already closed by round 1's broken toggle and the contiguous run HANDS IT BACK; and the obvious patch, 'only the first header run counts', is the same all-or-nothing failure section 1 rejects the whole-file fixed point for, reached by document order instead of by a stray line. Round 1's framing had a hole neither that reviewer nor the PMO saw. VERIFIED INDEPENDENTLY: the 21-shape catalogue cell-for-cell across three trees, six flips, nothing regressed, four legitimate rows still declaring, 09 and 12 confirmed fail-open on round 1; all 15 mutations on the reviewer's OWN harness with its own replacement lines, M9 through M13 each reddening exactly one named test, M1 disjoint from M2/M3, M14 reddening at the EXIT-CODE assertion; and the all-or-nothing replacement measured genuinely stronger rather than differently worded — one stray blank line voids all 23 of Perry's real declarations under a whole-file rule and 0 under the per-row rule. Suite on the merged tree 3c5f186: 101 modules / 3036 tests / 3 failures, exactly the PMO's figure, WITH NO FOURTH FAILURE — an eighth non-reproduction of the flake, which does not block. It also ran two checks nobody had: seven 'must still declare after a properly closed fence' shapes with no false refusals, and the human non-JSON status rendering. And it could not run declare, because the brief forbade it, so it COMPUTED what declare writes via render(parse(record)) and said so as a method note rather than claiming the command was exercised. TWO CORRECTIONS SENT BACK: section 9 mentions HTML blocks only in the fence-line direction, which reads as coverage — a bare canonical row inside 
 or an HTML comment still declares and is still laundered, identically at all three trees, filed as TASK-248; and section 4's 'no clause of the new mechanism can be deleted with the suite unchanged' should say FENCE RULE, since M16/M17 show two other clauses survive weakening with the suite green.

THE FAIL IS THE SENTENCE AFTER IT: a dynamic cover discharges a static hole only if the round MEASURES which sites it reaches and STATES the remainder — and this round states the remainder as EMPTY when it is TWELVE. Three things, none a redesign. (1) A DICT-CARRIED HEADER ROW ESCAPES BOTH HALVES, and it is NOT interprocedural as section 7 limit 1 claims: one line in bin/perry_store.py risk_plan, which already reads header, keys = table['header'], table['keys'], gives offenders_by_symbol == [] with all three header modules OK and the full suite at the same three failures. It escapes with NO MODULE BOUNDARY AT ALL — t = {'header': split_row(line)} then [squash(c) for c in t['header']] is local dataflow in one function, resolvable by the same _RowLocals machinery that already resolves aliases. And ['header'] is this repository's own idiom. (2) THE UNCOVERED SET IS NOT EMPTY: 17 live dict-key header reads, 12 in functions the watch never reaches; WATCHED is 16 functions against 45 holding the 59 call sites. Round 11 must COMPUTE the remainder and print the number and the list, not assert it. (3) WATCHED IS A GUARD THAT SURVIVES ITS OWN DELETION — removing an entry leaves all 8 tests green, and it is the mechanism the dynamic cover depends on. Also no DRIFT corpus entry plants a dict- or attribute-carried row, which the reviewer calls the same structure as round 9's charge with a different noun.

It rebuilt the sweep to take candidates from git diff rather than from itself: 128 candidates over the 337 new or changed lines, each mutated on the AST and re-emitted with ast.unparse so a multi-line condition cannot break syntax, with a control run that unparses without mutating and stays green, and every corpus-clean candidate re-probed against the runtime half so that green means the corpus is caught AND the remainder test is unmoved. Result: 60 red in the corpus, 26 red in the watch, 22 unneutralisable, 20 green. IT FOUND FOUR MORE UNPINNED DETECTION BRANCHES beyond the review's two — D44 _rpaths_of by attribute name, D45 _bind_element on a comprehension generator, D46 the cell() half of the tuple unpack, D47 the subscript half of the carried write — each now single-entry. The twenty remaining greens are claimed to contain NO detection branch and all twenty are named in section 1.5 with why a planting corpus cannot pin each, because that is a claim; two were re-verified by hand on the reasoning that a sweep disagreeing with a hand check is a broken sweep, and both agreed.

The test asserts four things behind a control that RUNS FIRST — the register really is nine records and assertGreater(staged.n, SUBSTITUTION_RECORDS_SHOWN), so on a narrower board the test dies on the control rather than passing. The four: the count is 7 and not 5, which kills the shortened-number mutation; exactly SUBSTITUTION_RECORDS_SHOWN identities are named, so the cap stays on the output; ', and 2 more' is present, which kills the tail deletion; and 'did not survive' rather than 'would not survive', the past-tense verb on a real write, which nothing had asserted.

Parsing that table has already cost twice, and both are TASK-050's defect class: parsers.py:415 records its split_row as 'the SIXTH implementation of this, found by a V4 reviewer after five were unified — it reads a row out of a regex group rather than off a line, which is why every sweep looking for strip(|).split(|) at the start of a line walked past it', and the line below it uses squash rather than .lower() because a bolded | **File** | header row was once read as a declaration.", "to": "V4 ROUND 3: FAIL, one specific defect, review at review/task-234-round3 742c89b. THE DEFECT: migrate_record's refusals name 'perry-conform migrate' WITH THE ROOT DROPPED, while message_for forty lines up propagates it via _root_flag(). A reader routed there by 'perry-conform migrate --root PROJ' who copies the command the refusal hands back gets rc=0 and 'nothing to convert — .perry/conformance.jsonl is already this project's record (or it has none)' — about a DIFFERENT project, with their own record still unconverted and still gating every write. Not an error: a success-shaped silence. That sentence was rewritten in this very round under the wall-standard banner and the omission was left in. All 16 helper invocations assert this message while themselves running with --root, which is why no test saw it. TWO NUMBERS CORRECTED: the helper is routed through by 14 distinct test methods / 16 invocations, not 17 — the reviewer measured it at runtime by wrapping the helper; 17 was section 4.3's count of MOVED tests, carried into a sentence about ROUTING. And only 4 of those 16 reach the fixed-point branch the FAIL was about; the other 12 satisfy 'locates' via the pre-existing 'line N:'. The equivalent-mutant claim SURVIVES challenge: the reviewer constructed bool(record.legacy), confirmed neither __bool__ nor __len__ appears in Path.__mro__ so every Path is truthy, and showed the control legacy_record=False is RED — the branch is load-bearing, only the spelling is indistinguishable. 17 mutations re-run independently, 16 killed, the 1 survivor is the declared equivalent one; '29/29' remains UNVERIFIED (M1-M14, M16-M21 not re-run).

WHAT HELD: MR-3 re-run confirms the row's claim exactly — only the new test dies, the old root.resolve() test stays green, same under a full revert; run_suite really does invoke bash tests/run; the 24/18 derivation is non-vacuous in BOTH directions (0o777 caught by os.access, 0o644 caught by assertTrue(execs)); the board-dependence gap is CLOSED, measured on three board states at 4/3 each; and the contaminated run STRENGTHENS rather than undermines the numbers. WHAT BROKE: the docstring pin's CLAIM is wider than the pin — it reads which of two STRINGS is in tests/run, not which mechanism shipped, so a live re-aim spelled 'export \"PERRY_PROJECT=$ROOT\"' or 'PERRY_PROJECT=...; export PERRY_PROJECT' evades the regex, and a refusal left dead under 'if false' still reads as 'refuse' — three green mutations.

On a planted project at '.../My Project' the refusal THIS ROUND REWROTE hands back 'perry-conform migrate --root /.../My Project'; copied verbatim it exits rc=1 with 'usage: perry-conform migrate — it takes no file', record unconverted. Same standard as the round-3 FAIL, same sentence, found the same way — and the standard is the row's own: 'a named command that errors is worse than none'. It covers all 14 handed-back commands in perry-conform and 4 in perry-migrate, including the message_for branch round 3 signed off. The row's own end-to-end proof runs shlex.split on the message and would go red today if one fixture root had a space. One-line fix. FOUR GREEN MUTATIONS: R-N3 and R-N4, two of rollback_message's three call sites in apply_plan (the write-failed and digest-mismatch paths, TASK-044 guarantee 3) can drop the caller's root with all of test_conformance AND test_migrate green — green because the tests that reach them call apply_plan(plan, SCHEMA) with no root, which is the round-3 defect one file over; controls R-N5 and R-N6 are both RED. R-N8: the SWEEP'S OWN ROOT regex neutered to match everything leaves the suite GREEN, because assertGreaterEqual(len(handed), 12) guards against finding nothing, not against calling everything ok — R-N9 is RED, so only the ok/bad half is unguarded. R-N13: deleting the update_expected_after(point, P.CONFORMANCE_LEGACY_FILE) call this branch added is green across test_migrate, because no test applies a migration to a project holding a legacy record and then restores it. TWO RESULT CLAIMS THAT DO NOT SURVIVE MEASUREMENT: section 6.1's 'M34 is invisible to BOTH' is false — M34 reddens 7 tests / 5 methods including 4 helper invocations, because assert_every_command_carries asserts the EXACT root; and M40 is M30 byte-for-byte, so 'caught only by reading the source' cannot hold for either.

FIVE full suites measured in-session, 4 failures across 3 red modules on every one (main at two different commits, the tip, and two merge probes), same four by name, no test_host_support; the arithmetic re-derived independently. BLOCKS MERGE, one bullet: .claude and .gstack are absent from tree_guard.py's 'What it does NOT catch, said plainly' list, while .DS_Store and __pycache__ — STRICTLY NARROWER holes — each have a bullet, and the row's own section 8.4 calls the .claude hole 'the widest of the five'. WHAT HELD: MR-3 re-run confirms the row's claim exactly — only the new test dies, the old root.resolve() test stays green, same under a full revert; run_suite really does invoke bash tests/run; the 24/18 derivation is non-vacuous in BOTH directions (0o777 caught by os.access, 0o644 caught by assertTrue(execs)); the board-dependence gap is CLOSED, measured on three board states at 4/3 each; and the contaminated run STRENGTHENS rather than undermines the numbers. WHAT BROKE: the docstring pin's CLAIM is wider than the pin — it reads which of two STRINGS is in tests/run, not which mechanism shipped, so a live re-aim spelled 'export \"PERRY_PROJECT=$ROOT\"' or 'PERRY_PROJECT=...; export PERRY_PROJECT' evades the regex, and a refusal left dead under 'if false' still reads as 'refuse' — three green mutations. All are caught by the BEHAVIOUR tests, so there is no hole in protection, only in what the test says about itself; but the admitted accuracy gap is TOTAL, since a bullet asserting the exact opposite behaviour, or cut to four words, leaves all 21 tests green. TWO NEW FINDINGS on the resolution fix: case-differing spellings are STILL falsely refused, and the fix NEWLY ACCEPTS relative paths whose meaning is cwd-dependent — a regression the fix introduced.

BLOCKER CLOSED and pinned: the bullet is in the 'What it does NOT catch' list carrying scope re-derived with controls — a directory appearing mid-run is invisible INCLUDING ITS OWN CREATION; with .claude/ already present at snapshot it is not in the manifest at all, so rewriting a file in it and creating another gives compare() == []; and the match is on the NAME AT ANY DEPTH, so perry/evidence/.claude/ and perry/.gstack/ are invisible while the same writes into .claudex/ are reported. The pin is the good part: test_every_ignored_name_is_a_bullet_in_the_list_of_what_is_missed is red when the bullet is deleted AND red when a fifth ignored directory is added WITH THE EQUALITY PIN MOVED WITH IT — which the equality pin alone would not catch. THE FIVE ITEMS: (1) it reproduced all three green mutations plus both bullet rewrites ON THE UNFIXED TIP FIRST, confirming the pin was green in all five, then took BOTH halves — the claim narrowed (class renamed to say it checks the bullet's VOCABULARY against the token spelled in tests/run, docstring states the measured gap) and the pin widened to catch both export spellings, with the refuse token anchored to a non-comment line. The dead-refusal-under-'if false' case stays uncatchable by string search and is recorded as such rather than papered over. (2) IndexError replaced by two FAILs with sentences, verified with both banners reworded. (3) case-differing spellings now accepted, comparison is 'test -ef' on device+inode. (4) relative paths REFUSED with their own banner and reason — decided, not incidental; the 17-spelling sweep re-run shows four changed, all in the intended direction, nothing became accept-everything. (5) 24 and 18 removed, grep returns nothing. TWENTY mutations, four green, all reported. MC1 is the most useful: reverting -ef to round 2's string comparison kills exactly one test and it is the new one — round 3's blindness finding, one layer out. THREE OF ITS OWN FIXES WERE GREEN UNDER THEIR FIRST MUTATION and were tightened: the relative-refusal assertion matched the word 'relative' in an explanatory paragraph rather than in the banner, setUp's terminator, and the doc pin would have passed on three empty sets. Five suites measured, 4/3 on every one including both board states of a moving main; the final tip differs from the probed merge only by the result document, and re-merging is clean."}

R-N8: the SWEEP'S OWN ROOT regex neutered to match everything leaves the suite GREEN, because assertGreaterEqual(len(handed), 12) guards against finding nothing, not against calling everything ok — R-N9 is RED, so only the ok/bad half is unguarded. R-N13: deleting the update_expected_after(point, P.CONFORMANCE_LEGACY_FILE) call this branch added is green across test_migrate, because no test applies a migration to a project holding a legacy record and then restores it. TWO RESULT CLAIMS THAT DO NOT SURVIVE MEASUREMENT: section 6.1's 'M34 is invisible to BOTH' is false — M34 reddens 7 tests / 5 methods including 4 helper invocations, because assert_every_command_carries asserts the EXACT root; and M40 is M30 byte-for-byte, so 'caught only by reading the source' cannot hold for either.

+> That file is a projection of `.perry/config.jsonl` now: `perry-config render`
+> rebuilds it from the store with no copy of it on disk, and what a store holds
+> is settings and track rows — never prose. Prose in the projection survives a

+
+### What the two tracks carry
+
+`intake` carries the work that ARRIVES — a defect an agent found mid-run, a
+sibling a sweep turned up, a review finding. It is not decomposed from a goal,
+it shows up, and its useful questions are queue questions: what has been
+waiting longest, how deep is the backlog, what keeps recurring.
+
+`main` carries the work that is DECOMPOSED — the phase, its KRs, the rows that
+serve them.
+
+Declared 2026-08-20 as the experiment in TASK-133. `Default rung` is V3 rather
+than queue mode's V2 default: an arriving row here is a code defect, and a
+resolution note is not evidence that it is fixed.
+
+### Why the state root is not `.`
+
+Perry's own `design/` directory is the **design lane skill**
+(`decide/SKILL.md`, `decide/state/design_TEMPLATE.md`), not a folder of design
+documents. Pointing the state root at the project root would make Perry claim
+its own source tree, and every lint run would report `decide/SKILL.md` as a
+malformed design doc.
+
+`okr/` and `pmo/` are lane skills for the same reason. `.perry/` stays at the
+project root: it holds this pointer, so it cannot sit behind it.
+
+This is the collision described in `perry/design/DESIGN-002-namespace-collision.md`
+— Perry is its own proof case, and this file is the escape hatch that document
+argues should be offered automatically rather than written by hand.
+
+See `schema/README.md § Where the files are`.

 Readable is not the consolation prize. `/perry diagnose` runs on any folder at all, and reading an unmigrated project is exactly how you decide whether to migrate it. And the migration owes you four things: the complete diff before anything is written, no lost rows or IDs, a restore point, and no step you did not ask for.

-### Both writers gate on the conformance marker
+### Nothing gates on a conformance marker any more
 
-Under [ADR-004](../perry/decisions/ADR-004-mandatory-migration.md) a project
-migrates to Perry's shape once, and after that both the reader and the writer
-may assume that shape. The fact that makes it safe to assume is **declared and
-checkable**, and it is not `perry-lint`'s `is_adopted()` — that answers "does
-this folder hold any Perry file at all", which is a different and still-correct
-question.
+`perry-task`, `perry-goals` and `perry_md_store § render --write` used to call
+an ADR-004 gate before every write: it read a **declaration** out of
+`.perry/conformance.jsonl` — *this file matches Perry's shape, at shape version
+N, and the user said so* — and refused when the file's live shape no longer
+matched what had been declared. Keeping the stored decision and the live check
+apart was the design, because the two disagreeing was supposed to be a finding.
 
-```bash
-"$PERRY_HOME/bin/perry-conform" status                  # every file, every verdict
-"$PERRY_HOME/bin/perry-conform" check BOARD.md          # one file; exit 1 if not conformant
-"$PERRY_HOME/bin/perry-conform" declare BOARD.md        # the user's declaration
-"$PERRY_HOME/bin/perry-conform" declare --all
-```
+They never disagreed. The ledger held 23 records, all `route: declare`, all
+files in this repository. The disagreement needs a foreign project that drifts,
+and Perry has never been pointed at one. `bin/perry-conform`, the ledger, the
+three gate call sites and `bin/perry-migrate` are all deleted (`TASK-261`,
+`USER-910`) — about 10,600 lines with their tests.
 
-Two facts, kept apart on purpose:
+**What replaced it: nothing, deliberately.** A writer that can render a file
+writes it. `perry-lint` still answers whether a file matches the schema, which
+was always a different question from whether anyone had declared it.
 
-| | Where it lives | Who produces it |
-|---|---|---|
-| **the declaration** — the user said this file is Perry's, at shape version N | `.perry/conformance.md` | only `perry-conform declare`, or a migration the user asked for. **No tool stamps it on its own initiative.** |
-| **the shape** — does it still match `schema/state-schema.json` | nowhere; recomputed every call | `perry-lint`'s own `check_file`, imported rather than reimplemented |
-
-A stored verdict would be a cache that goes wrong, and a content hash would
-revoke itself on every legitimate `perry-task add`. A stored *decision* plus a
-live *check* can disagree — and that disagreement (`drifted`) is a finding, not
-a crash and not a silent correction.
-
-Five verdicts: `conformant`, `undeclared`, `stale` (declared at an older shape
-version), `drifted` (declared, no longer matches), `absent` (nothing there yet,
-so nothing is gated). Conformance means **zero lint errors** for that one file —
-warnings are quality signals and one of them, `stale-run`, becomes true with the
-passage of time alone.
-
-Conformance is **per file**: a project may migrate its board and not its risks,
-so `perry-task` gates on `BOARD.md` and `perry-decide` on `DECISIONS.md`, and
-neither looks at the other.
-
-**Reading is never gated.** `perry-state`, `perry-task list`, `perry-goals list`,
-and `perry-decide list` answer on an unmarked project, whatever the gate is set
-to.
-
-The gate ships **enforce**: a writer refuses a state file that is not declared
-conformant, naming the file, the shape version it was checked against, and the
-command that fixes it. Set `- Conformance gate: advisory` in `.perry/config.md`,
-or `PERRY_CONFORMANCE=advisory` in the environment, to make it proceed and say
-what it found instead — on stderr and in the `conformance` block of its
-(non-contract) `--json` result.
-
-#### The switch-over checklist — what the flip to `enforce` costs
-
-ADR-004's decision was to flip once the migration existed. `bin/perry-migrate`
-landed with TASK-044 on 2026-08-19, so TASK-047 flipped `DEFAULT_MODE`. Every
-refusal now names a road: `perry-conform declare` for a file that already
-matches Perry's shape, `perry-migrate` for one that does not.
-
-The flip was **measured on a copy of a real project** rather than argued, and
-two costs came out of that measurement. Neither is a missing road; both are
-places a user meets the gate on day one, so both are stated here rather than
-discovered in the field.
-
-| | What it costs | What removes the cost |
-|---|---|---|
-| **1 · migration does not always reach zero on a real board** | On a `~/proj/gimegime-pmo` copy, `perry-migrate` takes `BOARD.md` from 3 errors to **1**, and the residue is a row reading `Status: 半解`. That file stays refused until a human edits it and runs `perry-conform declare BOARD.md`. The refusal names both commands, so it is a door that needs a hand — not a wall. | A path for the residue that is not a hand edit. The three classes seen were: a `Status` cell in the user's own words, a tier-1 file over its size cap, and a KR table whose columns are the project's. **Not** widening the enums — `半解` is a real distinction the user drew, and coercing it to `in_progress` is the confidently-wrong-value class. |
-| **2 · every new file is born undeclared, in a new project and an old one alike** | A file with **zero** lint errors is still `undeclared`, and undeclared is refused. `SKILL.md § Conformance gate` forbids an agent from running `perry-conform declare` on the user's behalf (`perry/OKR.md` — *adoption proposes; the user declares*), so the first `perry-task add` on a project Perry itself just wrote asks the user for one command. **This is not confined to first runs** — see the measurement below. | Setup or adopt ending in the user's own declaration — one prompt, at the point where the files are created. That is a better first run than a refusal, but it is a convenience, not a road: the road already exists and the refusal names it. |
+Two things kept the word and are unrelated to any of the above:
 
-Both are checked by `tests/test_conformance.py § TestTheGateEnforces`, so the day
-either becomes false a test says so rather than the paragraph going stale.
+- `perry-task list --json`'s `conformance.*` block — `evidence_not_found`,
+  `depends_on_unknown`, `blocked_by_closed_rows` — is read-time integrity
+  reporting and a published contract (`schema/task-list-contract.md`).
+- `perry-lint`'s schema pass, untouched.
 
-**Cost 2 was first written at the wrong scope, and the correction is the part
-worth keeping.** It read *a brand-new project asks for one declaration*, which
-is true and too narrow: the same thing happens to **every file Perry creates
-after the last declaration, in a project that has been declared for weeks**.
-Measured 2026-08-20 on a declared scratch project with the gate enforcing:
-
-```
-perry-decide bootstrap        →  wrote ['decisions/', 'DECISIONS.md']
-perry-conform status          →  · DECISIONS.md   undeclared
-perry-decide new  …     →  refused — DECISIONS.md already matches Perry's
-                                 shape at version 2, but no one has declared it
-```
-
-Two facts hold that together, and only both make it survivable:
-
-- **Creation is not gated.** The file is written. A gate that refused creation
-  would leave a project unable to open a phase, a decision or a knowledge card
-  at all, which is not a door needing a hand — it is the wall this checklist
-  exists to avoid.
-- **The next write to it is.** The refusal names `perry-conform declare` with
-  the exact path, so the road is one command, exactly as in row 1.
-
-Concretely, in Perry's own repository on the day of the flip: `phase/002`,
-`DESIGN-007` and one knowledge card were undeclared, because the last
-declaration ran 2026-08-17 and all three were created on the 18th and 19th. None
-of them was malformed. They were simply younger than the last time a human said
-*yes, this is Perry's shape*.
-
-This is a **consequence of the design, not a gap in it.** A writer that declared
-its own output would be certifying its own work, which is the thing ADR-004's
-*adoption proposes; the user declares* exists to prevent. Naming the real scope
-does not argue for changing it — it argues that "one declaration at setup" is
-the wrong mental model, and "a declaration each time the shape of your state
-grows" is the right one.
-
-**Going back is per project, not per release.** A project that wants the old
-behaviour sets `- Conformance gate: advisory` in `.perry/config.md`; a single
-command gets `PERRY_CONFORMANCE=advisory`. Both branches stay live and both stay
-exercised by the suite — a guard that cannot be made to fire is not a guard, and
-neither is one that cannot be turned off.
-
-What is **not** affected: reading. `perry-state`, `perry-task list`, `perry-goals
-list` and `perry-decide list` were re-run at every step of that migration with
-the gate enforcing, on an undeclared project, on a half-migrated one and on a
-declared one, and answered `rc=0` with all 41 rows every time. `perry-lint` and
-`perry-migrate` are ungated for the same reason — they are the commands a
-refusal names, and a gated one would close the loop.

-
-    - warnings in this schema are quality signals, not shape violations —
-      `done-needs-evidence`, `board-declares-no-rungs`, a soft `size-cap`. A
-      board can carry every one of them and still be a board every reader
-      parses correctly, which is the only thing a writer needs to know.
-    - some of them are *time-dependent*. `stale-run` fires when an adoption run
-      has been open 30 days; nothing about the file changed. A declaration that
-      revokes itself when a calendar boundary passes is not a statement about
-      shape.
-
-    **`check_file`, not `check_cross_file`.** ADR-004 § 5 makes conformance
-    per-file so a project can migrate its board and not its risks; a check that
-    spans files cannot be attributed to one of them."""

-ADVISORY = "advisory"

-
-#: Shipped **enforce** (TASK-047). This shipped `advisory` for one release, on
-#: an argument that named its own expiry condition, and the condition has now
-#: fired. The old text is not preserved here — a comment that explains why the
-#: default is `advisory` is wrong the moment the default is `enforce` — but the
-#: argument it made is, because a reviewer should be able to disagree with the
-#: flip on the same terms it was promised:
-#:
-#: The advisory release was NOT the DESIGN-003 decision-4 argument (a hard gate
-#: would retroactively invalidate work done before the rule existed). That one
-#: does not carry: a missing declaration on a conformant file can be produced in
-#: one second, retroactively, by one command. The argument that carried was
-#: narrower — for the projects that are NOT already Perry-shaped the way forward
-#: is the migration, the migration did not exist, and a refusal that names a
-#: command nobody can run is the wall ADR-004 § 4 forbids. Enforcement was to
-#: flip when TASK-044 gave the non-conformant half of the population a road.
-#:
-#: TASK-044 landed 2026-08-19. `bin/perry-migrate` exists, is dry-runnable,
-#: declares what it migrates with `route: migrate`, and names a restore point.
-#: Both halves of the population now have a road, and `message_for` below names
-#: it in every branch: `perry-conform declare` for a file that already matches,
-#: `perry-migrate` for one that does not.
-#:
-#: **What the flip costs, stated rather than discovered.** Neither of these is a
-#: reason the road is missing; both are reasons a user meets the gate on day one:
-#:
-#:  1. a complete migration does not always reach zero on a real board. Measured
-#:     on a copy of `~/proj/gimegime-pmo`: `BOARD.md` goes 3 errors → 1, and the
-#:     residue is a `Status` cell reading `半解` — a distinction its author drew,
-#:     which migration deliberately will not coerce into `in_progress`. That file
-#:     stays refused until a human edits it and declares it. The refusal says so
-#:     and names both commands; it is a door that needs a hand, not a wall.
-#:  2. a brand-new project has zero shape errors and is still `undeclared`,
-#:     because `SKILL.md § Conformance gate` forbids an agent from declaring on
-#:     the user's behalf — *adoption proposes; the user declares*. So the first
-#:     write on a spotless project asks for one `perry-conform declare BOARD.md`.
-#:
-#: Both are pinned as executable tests in `tests/test_conformance.py § 7`, so
-#: the day either stops being true a test says so instead of this paragraph
-#: quietly going stale.
-#:
-#: The escape hatches are unchanged and are the reason this is reversible per
-#: project rather than per release: `PERRY_CONFORMANCE=advisory` in the
-#: environment, or `- Conformance gate: advisory` in `.perry/config.md`.
-#: Advisory is not "off" and never was — the gate computes the same verdict and
-#: prints the same message, it simply writes anyway. A guard that cannot be made
-#: to fire is not a guard, so both branches stay exercised by the suite.

+"""
+perry-context-budget — how much context this session is paying for, per turn.
+
+**The number this exists for.** Measured across 25 Perry sessions and 18,941
+turns: 8.43 billion tokens, of which 99.1% is `cache_read` — the accumulated
+context, re-read on every single turn. Output was 0.3%. The largest session ran
+8,174 turns at a mean context of 504,651 tokens and touched 997,717 at its
+peak, compacting 15 times.
+
+So the cost of a long run is not what it loads. It is:
+
+    cost  ≈  Σ over turns ( context size at that turn )
+
+Both factors grow together inside one session, which makes a five-hour run
+superlinear rather than five times a one-hour run. Capping the second factor is
+the single largest lever available without changing what Perry does: on the
+measured sessions, holding context at 200k would have cost 58.3% less, and 300k
+42.3% less, for the same turns.
+
+`autopilot` reads this as a stop check. A run that crosses the ceiling writes a
+handoff and exits, and the next session resumes from the handoff at a fresh
+baseline — which is the whole reason `handoff/` exists.
+
+**It measures; it does not estimate.** The figure is the host's own accounting
+from the session transcript — `cache_read_input_tokens` plus
+`cache_creation_input_tokens` plus `input_tokens` on the most recent turn that
+reported usage. The transcript path and its mtime are printed with every
+answer, so the number is one somebody else can re-derive.
+
+**Read-only.** It opens one transcript and prints. It writes nothing anywhere.
+
+**When it cannot measure, it says so and does not gate.** Only `claude-code`
+keeps a transcript in a known place. On another host the verdict is `unknown`
+and the exit status is 0 — a gate that silently passes is worse than no gate,
+so this one announces that it abstained rather than reporting a clean bill.
+
+Usage:
+  perry-context-budget [--ceiling N] [--session ] [--json]
+  perry-context-budget --composition [--session ] [--json]
+
+  --ceiling      the budget. Accepts 200000 or 200k. Most specific wins:
+                 this flag, then env `PERRY_CONTEXT_CEILING`, then the
+                 project's `- Session context ceiling:` in `.perry/config.md`
+                 (or its store), then `schema § thresholds`. Every report
+                 names which of the four answered.
+  --session      measure this transcript instead of the newest one for the
+                 project. The escape hatch for "the newest file is not me".
+  --composition  scan the WHOLE transcript and report what the context is made
+                 of, by block type and by the biggest repeated shell commands.
+                 This is the diagnosis; the default mode is the gate.
+  --json         machine-readable.
+
+Exit status:
+  0  under the ceiling, or could not measure (verdict `unknown`)
+  1  at or over the ceiling — autopilot stops, hands off, and starts fresh

+no code path produced, and every Perry project reported `decisions.count = 0`
+forever. Found by a fresh-context review, verified.
 
 **The set of decisions was not readable from outside.** `perry-state` exposes
 `count`, `last` and `expired_sunsets` — a summary. A front-end could tell you
 there were eleven decisions and not one of their titles.
 
+**There is no rendered index, and its absence is a decision rather than an
+omission.** DESIGN-013 User Decision 3, answered 2026-08-29: `DECISIONS.md` was
+twelve rows of pure projection — 76% of its bytes inside table cells, no
+per-row prose — whose own third line told the reader it was generated and not
+to edit it. `perry-decide list` already printed the same content, so the file
+was a second copy of the ADR files' id, title, type, date and status. It is
+deleted, **not replaced**. § 4.1 of that design records what is given up with
+it — the markdown link surface into `decisions/ADR-*.md` that a reader browsing
+the repository on the web navigated by — and says in so many words that the
+implementing row must not quietly re-add an index under another name. So:
+`decisions/ADR-*.md` is the whole record, and `perry-decide list` is the whole
+view of it.

 Reading is deliberately tolerant. The ADR template and the ADRs people actually
 write already disagree: the template says `Sunset criteria`, real files say
 `Sunset`; real files carry a `Deciders` line the template never mentions; field

+#:
+#: `DECISIONS.md` was the only file this tool wrote that `schema/

+#:
+#: So the gate is removed rather than faked, and the hole is named here and in
+#: `perry/evidence/2026-08/TASK-235-result.md` instead of being left for a
+#: reviewer to find: **giving `decisions/ADR-*.md` a `files[]` shape is what
+#: would restore it, and that is new claim surface — its own row, not this
+#: one.** Until then `perry-decide` writes ADR bodies into an undeclared
+#: project, and **that is new.** This clause used to read "only the index write
+#: was ever gated", which is false and was caught by a V4 reviewer measuring it
+#: rather than reading it. The gate ran before the command, so it refused the
+#: WHOLE command: on `main` at `ee0b36a`, with `PERRY_CONFORMANCE=enforce` and
+#: nothing declared, `perry-decide new` returned **rc=1 and wrote no ADR body
+#: at all**, refusing with "DECISIONS.md already matches Perry's shape at
+#: version 2, but no one has declared it". On this branch the same call returns
+#: **rc=0 and writes `ADR-001`**. There is no reachable state on `main` where a
+#: body was written past the gate.
+#:
+#: So the honest size of the hole is: **the decide lane went from fully gated
+#: to not gated at all**, and whoever sizes the follow-up row should size it as
+#: restoring a gate, not as closing a gap that was mostly already open.

-perry-migrate — bring a project's existing state files to Perry's shape, once.
-
-ADR-004 makes migration the price of using Perry's write features, which makes
-this the only thing in Perry that rewrites a stranger's files. Its five
-guarantees are in `perry/evidence/2026-08/TASK-044-spec.md`; three of them are
-*assertions*, and that is why this is a program and not a paragraph:
-
-  1. **Dry run first, always.** `perry-migrate` with no subcommand plans and
-     prints the complete diff. It cannot write — `apply` is a different word.
-     The plan carries the full post-image of every file, so `apply` is
-     `path.write_text(plan.after)` and nothing else. The dry run and the real
-     run cannot diverge because there is one computation, not two.
-  2. **Nothing is lost, and nothing is changed into something else.** Two
-     groups of assertions run over every file before it is written, and a file
-     that fails any of them is not written at all. `losslessness()` asks
-     whether it is all still there — every non-whitespace character, every
-     table cell, every id, every per-section row count, and every line
-     accounted for. `meaning()` asks whether it still says the same thing —
-     because a legend widened into a task table, a `not yet locked` normalized
-     to `locked`, and a token spliced into a sentence about a vendor contract
-     all pass every check in the first group. Each part of `meaning()` states
-     what it cannot see; see the note above it.
-  3. **Recoverable.** Every run writes a restore point naming every file it
-     touched, with the bytes it found there. `perry-migrate restore` puts them
-     back. See § "Dirty tree or restore point" below.
-  4. **The user declares.** `apply` is the user's act, and it records the
-     declaration through `bin/perry-conform` — the one writer of
-     `.perry/conformance.md` — with `route: migrate`. There is no second record.
-  5. **Partial migration is a state.** Per file, never per project. A file is
-     migrated only if the plan takes it to zero shape errors; otherwise it is
-     left byte-identical and its remaining findings are named. So after any
-     run, every file is either exactly as its author left it, or conformant.
-
-Usage:
-  perry-migrate         [--root ] [--only ]... [--json]
-  perry-migrate apply   [--root ] [--only ]... [--json]
-                        [--no-declare]
-  perry-migrate restore [] [--root ] [--list] [--json]
-
-Exit codes:
-  0  the plan is complete / everything planned was applied
-  1  something could not be migrated, or a run was refused
-  2  bad invocation
-
-No LLM, no external dependencies (stdlib only). The default subcommand is
-read-only; `apply` and `restore` are the only writers.
-
-── What migration changes, and what it never touches ──────────────────────
-
-**Must change to be Perry-shaped** — the things a *reader* keys on by name:
-
-  · the presence of a required section heading (readers select by heading)
-  · the columns parsers resolve by name, in a table Perry already recognises
-  · the token in an enum-valued header field (behaviour gates on it)
-  · the presence of a required header field
-
-**Merely different** — never touched, in any file:
-
-  · any heading the schema does not require. `## Open — 工程线 · phase #004`
-    is 41 tasks under a name its author chose; `bin/perry-task` already reads
-    it as a `group`, and renaming it would be Perry deciding what someone's
-    workstream is called.
-  · heading text beyond the part the schema matches (`## P2 (低优先 carry)`
-    keeps its parenthetical)
-  · column order, row order, section order, extra columns, extra sections
-  · every cell, every line of prose, the language it is written in
-  · anything only a *warning* fires on. Warnings in this schema are quality
-    signals and some are time-dependent (`stale-run`); a migration that acted
-    on them would be a quality pass, which this is not.
-
-**Must change, but Perry may not decide** — reported, never guessed:
-
-  · an enum value that resolves to two candidates, or to none — including a
-    value that says only what it is *not*
-  · a table under a required heading that does not speak the schema's
-    vocabulary — Perry does not recognise it, and widening it would be writing
-    columns into somebody else's table. Sharing one column name is not
-    vocabulary: `ID`, `Status` and `Owner` are the commonest words in any
-    markdown table, and a two-row legend under `## P0` has an `ID` column.
-    `is_the_schemas_table()` states the test and what it cannot see.
-  · a field-shaped sentence in the body. `Status:` in a paragraph is prose;
-    only the header block is Perry's to write into
-  · a file over its size cap: splitting it is a content decision
-  · a required section whose *content* the schema constrains
-
-── A file whose mode says read-only ───────────────────────────────────────
-
-Migration replaces it, and now says so. `write_atomic` stages a temp file and
-calls `os.replace`, and a rename needs write permission on the *directory*,
-not on the target — so a file its author `chmod -w`'d was migrated like any
-other and nothing in the plan mentioned the bit. It is named in the per-file
-list in both modes, with the mode it was found in, because `TASK-044-spec`
-asks that list for "every file it touched, with what changed in each" and a
-permission the run crossed belongs to that answer.
-
-That is a report, not a decision. Whether migration should refuse such a file
-instead is `USER-004` and is open; nothing here answers it, and the behaviour
-is unchanged — the file is migrated, its mode is left as found, and the
-restore point carries its original bytes.
-
-── Dirty tree or restore point ────────────────────────────────────────────
-
-TASK-044 § 3 asks for one of the two, and says why the choice needs stating.
-
-This writes a **restore point**, and does not refuse on a dirty tree.
-
-Refusing on a dirty working tree answers the question only for projects under
-git, and `~/proj/gimegime-pmo` — the project this was built against — is a
-local-only repo whose state files are routinely uncommitted. A guarantee that
-is absent exactly where the risk is highest is not a guarantee. It is also
-weaker than it looks on projects that *do* use git: state files are frequently
-untracked or ignored, and `git checkout` cannot restore what git never saw.
-
-So recovery is Perry's own, works identically in both cases, and is exercised
-rather than described: `.perry/migrate/.json` holds the bytes of every
-file the run touched — including `.perry/conformance.md`, because the run
-wrote that too and a restore that left the record behind would claim
-conformance for files that no longer have it.
-
-The cost, stated: this is state Perry now owns, and it holds a copy of the
-project's own writing. It lives under `.perry/`, which is already Perry's
-namespace; it is JSON, so it is invisible to `perry-lint --claims`, which
-globs `*.md`; and `perry-migrate restore --list` is how you find one.
-
-A dirty git tree is *reported* in the output, because it changes what a `git
-checkout` would undo — but it is not a refusal.

-      away from migrating. That is the safe direction of the two.
-    - **it counts names, not meaning.** A legend whose columns happened to be a
-      majority of the schema's would pass. `meaning()`'s reading assertion is

-# appended Perry's metadata to somebody else's disclaimer, and why three more of
-# the same class shipped after it: a legend widened into a task table, a status

-#                     does not exist to turn a *row* into a record.
-#   · `prose`       — a line Perry rewrote must be a line the schema gives it a
-#                     place to write: a table row, or the header block.
-#   · `enum_claims` — a canonical value written into a field must still be what

+    0, and every write is then refused forever while `verify`, `diff` and

+    parsed to zero records has answered nothing, and an interrupted write does
+    produce one — but the claim under it is retracted rather than left
+    standing. The real fix is at the WRITER, and is filed to `## Intake`.

+    shipped a different predicate and each ended in the same defect — an
+    ordinary command silently truncating a canonical register store, exit code
+    0, `perry-lint` reporting the wreck as clean.
+
+    Round 1 keyed the exemption on the COMMAND NAME. Round 2 keyed it on an
+    identity TUPLE that was not unique. Round 3 keyed it on the section's
+    SHAPE — and the shape is read at a moment the command controls, because
+    `cmd_add`'s queue branch calls `ensure_section("Intake")` before `commit()`
+    ever asks. Each fix was principled and each moved the question one step
+    without answering it.
+
+    This asks no question about the command, the identity or the board. It
+    asks the only thing that is invariant across all four doors: **did the
+    derivation produce fewer records than the store already holds?** A gate
+    that is read too late still counts the same rows; a shape the gate cannot
+    read derives to `[]`, and `0 < n` is the refusal; an identity that cannot
+    identify cannot conjure a row out of nothing. Option A — evaluating the
+    gate against the board as it stood at command entry — was explicitly
+    rejected, and this is why it is not needed: WHEN you look does not change
+    HOW MANY there are.
+
+    A shrink is not always wrong; it is wrong when nobody asked for it — and
+    **it is wrong past the point somebody asked for.** Round 4's fifth door was
+    not inside this function; it was the exemption around it, granted by name
+    and without a bound, which let `resolve-intake` — a command that removes no
+    record at all — persist a 24-record loss it never performed. So the
+    exemption is a number, `declared_removal(event)`, and the question is not
+    "may this command shrink" but "is the drop the drop the caller declared".
+
+    That is still one question about two integers. It asks nothing about the
+    command's identity, nothing about the board, and nothing about when the
+    gate is read: option A stays rejected, because WHEN you look still does not
+    change HOW MANY there are, and now neither does WHO is looking.
+
+    The event dict is taken whole rather than as a name, deliberately: the

+    forget to pass its bound. There is no way to reach this function with the

-Before drafting any ADR, **read `.perry/config.md` § Document language**. The ADR's narrative content — Context, Options, Chosen, Consequences, Sunset criteria — MUST be written in that language. Citations (file paths, commit SHAs, code refs, evidence paths), the ADR id, and the `Type:` / `Status:` / `Date:` / `Supersedes:` **values** stay English regardless — they are matched by `bin/perry-state` and every downstream reader. The `DECISIONS.md` index heading and its column headers localize through the glossary (`## Active` → `## 进行中`, `| ADR | Title | Type | Date |` → `| ADR | 标题 | 类型 | 日期 |`); the full contract, including which field *names* may be localized and which may not, is `$PERRY_HOME/reference/i18n.md`.

 This rule applies to all PMO-written artifacts but is called out explicitly here because ADRs are long-lived records the user reads months later. Mixed-language ADRs are hard to skim — one language per file, end to end.

    Two things to get right, because a reader can't recover from either:
    - **`target` / `current` are numbers or omitted.** A KR whose target is prose ("≤ 15% drawdown", "6–10% annualised") carries no `target` — the number goes in `metric` as text. A ceiling rendered as a progress bar reports a risk limit as two-thirds achieved. **`current` is an author's assertion: leave it out until someone asserts one.** The template no longer carries `current: 0`, because most KRs drive a count down and a defaulted zero reads as met on the day the register is written.
    - **`unlinked` starts empty and is only ever appended deliberately.** It means "this work serves no KR", not "we haven't got round to it".
 
    This graph is the stable-ID source of truth that keeps attribution from being guessed later, and it is what the frontend draws the O→KR→task chain from. See `$PERRY_HOME/reference/okr-linkage.md`.

+table `phase/<NNN>-<slug>.md` used to carry.
+
+**Why the phase document no longer carries it.** Those four facts were written
+in both files, in full: by hand here at `plan-phase` step 7, and machine-written
+into the register by `bin/perry-goals link`. Nothing compared the two —
+`perry-lint` reports drift for six declared stores and had nothing to say about
+this pair — and the markdown copy is the one that went stale. Measured at
+`30cc467`, every one of the 24 KR rows across phases 001, 002 and 003 disagreed
+with its register, and `P003-O2-KR1` carried a target the register did not.
+DESIGN-013 § 5.1 (locked 2026-08-29): *a fact that has a schema lives in exactly
+one store; a document holds what has no schema; no field lives in both.*
+TASK-157 is the row.
+
+**What this command will never do.** It has no `--write` and refuses one. The
+alternative design — generate the table back into the phase document and report
+hand edits to it as drift — was the row's original scope and was rejected under
+the rule above: it builds a second copy and then a checker for it. There is
+nothing to reconcile here because there is nothing to reconcile against.
+
+**On a project that has not migrated** — an adopted one, or a Perry project
+older than this row — the phase document still carries a table and the register
+carries no `krs[]`. `viewer/parsers.py § phase_key_results` reads the document
+exactly then, so those KRs still reach every payload. One source at a time,
+chosen, never merged; `krs` itself needs a register and says so if there is none.

+| 2026-08-29 | a session cannot tell 'no writer ran' from 'no writer ran INSIDE MY TRANSCRIPT' — TASK-226's phantom row was the documented writer invoked by the user in their own shell, and the session concluded a contract violation from the absence of a tool call in its own history; every 'nobody did X' claim this project makes has the same blind spot, and the machine's own record (shell history, mtimes, the event log) is the check | — |
+| 2026-08-30 | test_contract_key_parity's two witness tests are DATA-DEPENDENT on the live board — they fail whenever conformance.in_progress_with_no_live_run is non-empty, which is true of any repository with a row left in_progress and no dispatch marker for 4h; measured 2026-08-30 identical on 7f934d5 and on the pre-merge 9b53315, so a baseline of '3 failures' is only true of a board with no stalled rows. Third instance of this class after test_diagnose's queue-reconcile and the scratchpad-baseline race, and the first where the failing check is CORRECT — it is reporting a true fact about the board | — |
+| 2026-08-30 | measuring one tree's tool with another tree's PERRY_HOME silently loads the wrong schema and produces a confident wrong answer — the TASK-235 agent's first check APPEARED to refute its reviewer this way (main's perry-decide + the branch's PERRY_HOME found no files[id=decisions] and returned 'absent'), and every cross-tree measurement this project makes has the same trap; recorded in that row's RESULT section 7 B | — |

This is ADR-007 rule 2 violated by a test: a field with an unbounded value space is prose and no regex asks it a question. The fix is to assert on the field's own CELL, not the row. Fourth data-dependent test found in two days and the second whose data is the PMO's own writing | — |
+| 2026-08-30 | the 'two runners disagree by 3' figure was carried across four rounds and three briefs before anyone ran it — measured 2026-08-30 on ee0b36a: bash tests/run 2882/3, python3 -m unittest discover -s tests 2882/6 with skipped=4. It is true. But TASK-050 round 8 retracted it as unmeasured, this session's own review briefs asserted it, and it took a row whose deliverable was a RESULT document to actually run the command; a figure everyone repeats and nobody measures is the shape this project exists to catch | — |
+| 2026-08-30 | tests/test_intake_store.py's test_a_row_deleted_by_hand_reports_every_row_it_renumbered builds the exact dangerous precondition — a ## Intake row deleted by hand against a minted store — and then runs only perry-lint, so NOTHING in the whole suite ever runs a shrink-permitted command on that board; the state was constructed and then not used, which is one line short of catching the entire TASK-203 round 4 defect class. A test that builds the dangerous state and asserts something safe about it is worse than no test, because it reads as coverage — sweep for the same shape elsewhere | — |
+| 2026-08-30 | perry-tasks accepts --dry-run silently and WRITES ANYWAY — the flag is not in its help and not implemented, and the PMO used it on intake-write --from-board and asks-write --from-board on 2026-08-30 expecting a preview; both files were really created, 32 and 13 records. The output even reads 'wrote /…/intake.jsonl (32 intake record(s))', which is honest about the write and gives no hint the flag was ignored. perry-task DOES implement --dry-run, so the two halves of the same toolchain disagree about whether the flag exists, and the write-side one fails OPEN. An unrecognized flag on a write tool must be a refusal, not a silent write | — |
+| 2026-08-30 | the PMO put a stale figure into three review briefs: 'a live-board tree measures 5 failures, the two extra being test_contract_key_parity's witness tests'. It was true when measured and is not now — in_progress_with_no_live_run is EMPTY while the in-flight rows hold live dispatch markers, so the tree measures 3. TASK-241's agent hit the discrepancy, correctly did not chase it, and reported it. Same failure mode the PMO filed against the project four hours earlier: a figure everyone repeats and nobody re-measures. Any number handed to an agent must carry the state it depends on, not just its value | — |
+| 2026-08-30 | perry-config render --write recreates a DELETED .perry/config.md even under the enforce gate, because verdict() returns ABSENT for a missing file and ABSENT counts as ok — so a file that IS declared conformant on this project gets written by a tool the gate never asked. Pre-existing, unchanged by TASK-233, and probably right; nobody has written down why. Found by the TASK-233 agent against code it did not touch | — |
+| 2026-08-30 | tests/gate.py GATE_OFF appended to a config that already has ## sections MINTS NO STORE RECORD — four fixtures were doing exactly that, and it only ever worked because the old gate_mode scanned the whole file with a regex rather than reading a record. TASK-233 ships gate_off(text) and gate_off_record() as the fix, but the class is broader: any test helper that edits config MARKDOWN to change behaviour is writing to a projection, and every one of those stops working the moment its reader converts to the store | — |
+| 2026-08-30 | a stray perry-task intake-sweep event with actor 'agent' was written into the TASK-241 worktree's own .perry/events.jsonl and journal at 2026-08-30T04:55:05, and rode along in that branch's RESULT commit — it is NOT on main and the PMO did not run it. Either the agent ran a write-side tool in its own tree, or something in the SUITE runs perry-task against the tree it is running in rather than a temp root, which would mean the test suite writes PMO records into whatever worktree executes it. The second reading is the one worth checking, because every agent tonight ran bash tests/run in its own worktree. Caught only because the merge conflicted on an append-only file; a fast-forward would have carried it into main silently | — |
+| 2026-08-30 | test_heading_title's test_none_of_them_contains_its_own_id assumes ONE evidence document per row, and fires on a legitimate multi-row one: perry/evidence/2026-08/TASK-050-053-057-060-v4-review.md is headed 'V4 review — TASK-050 / 053 / 057 / 060', which is what a document covering four rows SHOULD be called. Measured 2026-08-30: the file is from 2026-08-18, the test was green at d527942^ and red after TASK-050 was closed — closing a row changed which evidence the walk attributes to it and surfaced a twelve-day-old violation. The file must NOT be renamed to satisfy the check; rewriting a historical evidence document to make a test pass is the failure this project guards against everywhere else. The rule needs to express 'a title may name the rows it covers when it covers more than one', or the walk needs to stop attributing a multi-row document to each row in it | — |
+| 2026-08-30 | test_host_support's test_concurrent_mixed_registers_do_not_exceed_global_cap flaked again 2026-08-30: once in a full run on coding/task-249-suite-writes, then green/green/red/green on standalone re-runs including once at the fork point. Third night it has been observed. TASK-230 measured it 2 of 10 under longest-first and 0 of 5 under alphabetical and DECLINED to claim a schedule effect, which was ruled correct; this observation is on a branch that touches neither the module nor the runner, so it is further evidence the cause is the test rather than anything around it. Its own measurement is a repeated single-module run, which nobody has done | — |
+| 2026-08-30 | perry-decide status and supersede REWRITE A FOREIGN ADR BODY — measured 2026-08-30 by the TASK-239 agent: '> Status: Proposed' becomes 'archived', rc=0, no warning. Not fixable by declaring a shape, because that file already IS Perry's shape; it needs claims[] (DESIGN-002). Two siblings from the same round: perry-decide new mints into a decisions/ directory Perry did not create, because bootstrap refuses an existing directory while new requires one and never asks who made it, and adr-tools-named files are invisible to the ADR-*.md glob; and perry-decide supersede prints 'wrote None' | — |
+| 2026-08-30 | perry-knowledge promote writes a files[]-shaped path WITH NO GATE either, so ADR-004's 'every writer gates on it' was already not literally true BEFORE TASK-235 deleted the decide lane's only gateable file. Found by the TASK-239 agent while establishing that the decide lane should be exempt — it changes what that exemption means, because an exemption argued as 'this lane is special' is weaker if another lane was already ungated by accident. Not investigated | — |
+| 2026-08-30 | the baseline dispute settles as 'the number is not a property of the commit'. On a clean git archive of main HEAD at 09:42 the suite gives FOUR failures including test_heading_title; the TASK-239 agent got 4 at 49d83fc at 08:56; the TASK-249 agent got 3 at the same commit at 09:21. Same commits, different hours, different numbers — because test_heading_title's walk attributes evidence to rows through the board, and the board changed between those runs as rows were filed. Three of the suite's failures are now known data-dependent: two on conformance.in_progress_with_no_live_run, one on whether a row's Next action prose contains an enum word, and this third on which evidence document the walk attributes to which row. A suite whose failure count moves with the project's own record cannot be used to decide whether a branch regressed anything unless both sides are measured in the same minute | — |
+| 2026-08-30 | test_one_header_rule.py's TestTheFifthCopy had gone VACUOUS — every probe returned ([], []) and compared nothing to nothing. Found by the TASK-234 agent while converting the conformance record, repointed and given an anti-vacuity assertion in that branch. Worth a sweep: it is the sixth vacuous or self-satisfying test found on this project in three days, after a hand-built board that parsed zero rows, a test that grepped its own docstring, a control that could not fail, a test built on a clean board where the failure was impossible, and a substring assertion that read its own explanatory comment as the defect. Every one was found by an agent doing something else | — |
+| 2026-08-30 | A signed-off test pins a line number by hand and it moved twice in one row (adoption-suppression, 374 -> 402): raised by the TASK-239 agent against its own work. A pin that must be re-pinned every time the section above it grows is pinning the layout, not the behaviour, and each re-pin can silently re-point it at the wrong line while the test stays green. Decide whether it should anchor on text; if a line number is genuinely the only handle, the test should say why. | — |
+| 2026-08-30 | Two V4 reviewers measured the SAME commit within an hour and got different failure counts (4/3 and 5/4 at main@5367c06); the difference is the recorded test_host_support flake, but nothing in the suite output says so. A reviewer who measures 5 has no way to tell a flake from a regression except by asking another reviewer, and the second measurement is exactly what a review is supposed to make unnecessary. Either the flake is quarantined and named in the output, or the suite prints its own known-flaky set so a count that includes one is legible as such. Related: TASK-251 (three numbers that all look like a failure count). | — |
+| 2026-08-30 | The PMO handed a wrong baseline to a review brief: I wrote '4 failures across 2 red modules' when it is 3, and omitted the test_host_support flake that makes a first run on a fresh worktree read 5/4. The TASK-249 reviewer caught and corrected it. This is the same defect the project just wrote a knowledge card about (verification/numbers-migrate-between-sentences) committed by the person who wrote the card, in a brief sent an hour later. Filed against the PMO. The fix is not more care: review briefs should carry the command that produces the baseline instead of the baseline, so the reviewer measures rather than trusts. | — |
+| 2026-08-30 | The tree guard cannot see a new top-level DIRECTORY it ignores by name, and one such hole is now taken knowingly: measured on TASK-249 round 3, with .claude/, .gstack/ and .ruff_cache/ all appearing between snapshot and verify, only .ruff_cache is reported and '+ .claude' is not, because dirnames are filtered before directory entries are recorded. So an ignore entry does not merely suppress a known-noisy path, it blinds the guard to that path appearing at all. Decide whether ignoring a directory should still report its APPEARANCE while suppressing its contents. | — |
+| 2026-08-30 | The tree guard's ignore list matches a directory name AT ANY DEPTH, and a file written inside an already-existing ignored directory is invisible — both reproduced by the TASK-249 round-3 reviewer, and both wider than the row had recorded. The row's own section 8.4 already calls this 'the widest of the five' holes. So an entry meant to suppress one noisy top-level path silently exempts every directory of that name anywhere in the tree, contents included. Decide whether ignore entries should be anchored to the top level, and whether an ignored directory's APPEARANCE should still be reported while its contents are suppressed. Supersedes the narrower row filed earlier today. | — |

Depends on TASK-237 delivering the render. The KR's own wording is a goals-lane edit and is handed off in handoff/2026-08-29-goals-lane-after-design-013.md; this row does not wait on that edit to be startable, but the two must agree before it closes.

DESIGN-009 section 6 step 2 states its own purpose: 'perry-okr render reproduces OKR.md byte-for-byte with objective rows in the store. THIS IS THE GATE: if the renderer cannot rebuild the five headings from records, the records are wrong.' That gate proves okr.jsonl holds everything OKR.md's tables hold — which is exactly the thing this row must know before it deletes them. Run in the other order and the gate evaporates: with the tables already gone there is nothing left to rebuild, so TASK-182 would pass vacuously and nobody would learn whether the store was complete. That is the same class of defect this project has caught six times — a check that cannot fail on the thing it names. The read-surface report is not a courtesy: DESIGN-013's risk table says if it comes back negative, TASK-237 STOPS and returns to the design rather than proceeding because the decision was already made. Write it as a finding, not as a justification for having done the work. | — | V4 | TASK-235, TASK-181, TASK-182 | main |  |  |  |  |  |  |

DESIGN-013's risk table is explicit — if that report is negative this row STOPS and returns to the design, rather than proceeding because the decision was already made. Also note for the goals lane, not this row's write: P003-O2-KR3 is 'BOARD.md's two truth models are marked in the file' and TASK-199 is its only row. Deleting the file moots both.

Start from the reviewer's measurement rather than re-deriving it: evidence/2026-08/TASK-235-v4-review.md carries both exit codes on both trees. The first question is not how to gate it but WHETHER ADR-004 was ever meant to cover a lane whose artefacts are prose documents — ADR-007 rule 3 says the Python layer never parses a document at all, and a conformance gate is a shape check on a document. | evidence/2026-08/TASK-239-spec.md | V4 | TASK-235 | main |  |  |  |  |  |  |

+| TASK-244 | the suite's floor is one module: test_task_writer.py runs alone for 105-149s and no worker count moves it | Coding Agent | not_started | Blocked until TASK-230 lands. PREMISE CORRECTED 2026-08-30 by TASK-230's own post-review measurement — read this before starting, because the row was filed on a number that has since moved. On a QUIET machine bash tests/run on the corrected tree is 108.9s, UNDER the two-minute target, red on exactly the same five tests, with CPU identical to a 266.7s run (341.1s user + 157.0s sys against 338.6s + 153.9s) — identical work, less than half the wall. A follow-up --times run took 126.3s while test_task_writer.py took 126.28s: the suite finished 0.02 SECONDS after its longest module, which independently reproduces the reviewer's 246.74-of-246.8 observation. So the floor is real and the schedule is optimal — 'optimal is one module long' — but the target is NOT structurally unreachable the way this row was filed. It is reachable on a quiet machine and unreachable on a loaded one, and the module's own 105-149s is the whole margin. That changes what this row is for: not 'get under two minutes', which the machine already does when it is idle, but 'stop one module owning the floor', so the number holds under the load this project actually runs at.

THREE sites, not two — the third came from TASK-233 round 2's reviewer: bin/perry-migrate:228 board_language() returns 'en' as soon as .perry/config.md is absent, so a store-only project migrates into English no matter what its store declares. That one differs from the other two: it is not an 'installed' question but a LANGUAGE default, and getting it wrong writes a board in the wrong language rather than reporting a project as unconfigured. Start from evidence/2026-08/TASK-233-round2-v4-review.md and evidence/2026-08/TASK-233-result.md, which carry the grep and the classification of every hit. TASK-233 round 2 proved by cross-check that its own two sites fail under DIFFERENT conditions and that one test covering both would have been a false guard — assume the same here until measured otherwise, and give each of the three its own named test and its own mutation.

+| USER-904 | TASK-050 has now failed SEVEN V4 rounds and needs a decision, not a round 8. Each round's fix moved the same defect rather than closing it: round 5's reviewer defeated a regex, round 6 replaced it with an AST walk, and round 7 showed the walk's gate is still an allowlist of variable names (ROW_NAMES, 11 entries). Measured: of 829 mapping constructs in the 18 readers, 59 are classified as row-cell sources and 35 of those are the bare name 'header'; FOUR LIVE header resolutions (viewer/parsers.py:1827, bin/perry-task:6029 and :6200, bin/perry-tasks:925) can be reverted to the exact historical defect with the whole 2793-test suite green, and parsers.py:1827 silently drops a KR when reverted. In the other direction the check now reports CORRECT code — 6 of 8 legitimate shapes flagged, including the exact latent risk round 5 recorded. Blind to four of the tree's own header resolutions AND loud about a keyword tokenizer: both failure modes the spec names, in one artefact. THE CHOICE. (A) Round 8, same shape — widen the source-expression recognition. The record says this is the fourth time that has moved the defect. (B) Invert the burden: flag EVERY case-folding map in a reader, and require the ~30 legitimate value normalizers to carry a one-line opt-out marker. Correct code declares itself once; anything new is caught by default. Cost: touching 30 live sites and a new convention. (C) RECOMMENDED — make it structurally impossible: one header_index() function becomes the only thing allowed to fold a header, and the guard becomes 'nothing outside it calls squash on a row', which is a one-symbol surface instead of a shape. This is the move ADR-007 already made for stores. (D) Accept the guard as advisory rather than a gate, close the row at a lower rung, and document the limitation. My recommendation is C, with B as the fallback. All four are design decisions with blast radius beyond this row, which is why this is an ask and not a dispatch.

+| USER-905 | TASK-095 has now failed FIVE V4 rounds and needs a decision, not a round 6. I caused three of the five, and every one is the same shape: two situations answered as one, one step to the left of the last. Round 1 collapsed four None-returns. Round 2 collapsed 'no-track-record' into unusable and hard-blocked three of this repo's own fixtures. Round 3 collapsed the two default cases. Round 4 filtered on the NAME 'main' instead of on whether the table DECLARED it. Round 5 compares on names over records, so a record that CONTRADICTS a declared row counts as carrying it. THE DECISION, and the reviewer states it cleanly: two principles are each defensible applied once, and round 5 applies one to the synthesised main and the other to the recorded main. (A) 'A declared row the register contradicts is drift' — then a table declaring queue/4/3d beside a store recording project must WARN, and perry-lint already computes exactly that. (B) 'The store is truth and the table is a stale projection' — then the trackless case must be SILENT too, because the register answered there as well. Pick one and it applies everywhere; the current code cannot be right because it holds both. SECOND, SEPARATE DECISION — the refusal WIDTH, and it is urgent because I made it worse: I widened the write refusal from source=store-default to source=store, and the reviewer measured three ordinary hand-edit workflows now hard-blocked that wrote at 45a355d AND at round 4. On the third — derive the store from a two-track table, then hand-swap one row — 'perry-config write --from-file', the ONLY command both refusal messages name, exits 1. The block cannot be cleared by the documented remedy. Options: revert to round 4's narrower width; make it a warning rather than a refusal; or fix perry-config so the remedy works. THIRD: the perry-goals half of the guard is a tautology — deleting it leaves the full 2875-test suite at exactly the baseline, which is the same defect TestTheGoalsLaneRefusesToo's own docstring records against round 2. My recommendation: (A) for the principle, because perry-lint already owns that rule and the root cause across three rounds has been re-deriving it differently; plus revert the refusal width to round 4's until perry-config's remedy is fixed. All of this is on an UNMERGED branch, so nothing is harmed in production.

+| USER-906 | TASK-203 has now failed THREE V4 rounds, all three mine, and every one has ended with the same defect: an ordinary command silently truncates a canonical register store. I said I would escalate rather than attempt a fourth, so here it is. ROUND 3's FAIL: the gate is read at a moment the command controls. cmd_add's queue-mode branch calls ensure_section('Intake') BEFORE commit() asks the gate, so the gate sees a freshly created, readable, EMPTY table, answers yes, derives [] and writes zero bytes. Measured: a 291-byte 3-record intake.jsonl goes to 0 on 'perry-task add --track ops' with rc 0, byte-identical on 45a355d, and perry-lint reports '0 row(s) drifted'. It is round 1's blocking finding word for word — round 2 closed it for the project-mode track and never asked the queue-mode track, which is the mode ## Intake exists for. Three more doors of the same shape: intake 3->1, ask 3->1, risk-add 3->1, all rc 0, all preserved on base. THE DECISION. (A) Evaluate the gate against the board AS IT WAS AT COMMAND ENTRY, not after the command mutated it — snapshot the shape before any board write. Principled and small, but it is the fourth 'move the question' fix on this row and the first three all looked principled too. (B) RECOMMENDED — make it structurally impossible: an ordinary write may never SHRINK a canonical store. Only an explicit removal command (purge, resolve-intake, intake-sweep) may reduce the record count, and any derivation that would produce fewer records than the store holds is a refusal, not a write. That is one invariant covering every door found in three rounds — the command name, the non-unique tuple, the four section shapes, and the ensure_section ordering — instead of a fourth predicate. (C) Revert TASK-203 entirely and reconsider the row. It has introduced a store-truncation regression in all three rounds; before it, intake.jsonl did not exist and could not be wrong. That is a real 'should we do this at all' question and it deserves an answer, not an assumption. (D) Narrow the scope to the risks register only, which is the one that already existed, and defer intake/asks. NOTE THIS AFFECTS THE PHASE: TASK-203 is the ONLY row under P003-O1-KR1, and DoD Must-Have 2 names intake.jsonl and asks.jsonl explicitly, so (C) or (D) means the phase misses that Must-Have deliberately rather than by accident. Also filed from this round: my third shape test is VACUOUS (the legend table lands under ## Top risks because ensure_section anchors ## Intake before ## P0, so the foreign shape has no test on any register); the uniqueness test cannot distinguish uniqueness from adjacency; load_register_records lets a JSONDecodeError escape as an uncaught traceback where every other failure in that file is a Refused. Evidence: evidence/2026-08/TASK-203-round3-v4-review.md. | TASK-203 |  | answered 2026-08-29: 决定 2026-08-29（用户拍板，Perry 推荐 B）：选 B —— 一条不变量取代第四个谓词。普通写入永远不得缩小一个 canonical store：只有显式的移除命令（purge、resolve-intake、intake-sweep）可以减少记录数，任何会产出比 store 现有记录更少的推导都是 refusal 而不是写入。这一条覆盖三轮里找到的全部四扇门 —— 命令名、非唯一元组、四种 section 形状、ensure_section 的顺序 —— 而不是再加一个「门在什么时刻被读」的判断。不选 A：那是这一行上第四次「把问题挪一步」，前三次看上去也都有原则。不选 C/D：DoD Must-Have 2 明文点名 intake.jsonl 和 asks.jsonl，这条 Must-Have 保留，phase 003 不放弃它。同轮附带的三项一并修：第三个 shape 测试是空测（legend 落在 ## Top risks 之下，foreign 形状在任何 register 上都没有测试）；唯一性测试分不清唯一性与相邻；load_register_records 让 JSONDecodeError 以裸 traceback 逃逸，而该文件里其他每个失败都是 Refused。 | 2026-08-29 |
+| USER-907 | ADR-010 deletes BOARD.md, which makes P003-O2-KR3 unmeetable mid-phase — the KR is 'BOARD.md's two truth models are marked in the file' and TASK-199 is its only row. A boundary cannot be marked in a file that is gone. This needs your decision because dropping a KR changes what phase 003's Definition of Done MEANS, and the phase is live. THREE OPTIONS. (a) RESTATE the KR as something ADR-010 can satisfy — 'the render distinguishes what is projected from what is canonical' — which is the same reader-facing property the KR was actually buying, on a surface that will exist; TASK-199 is re-scoped rather than dropped. This is my recommendation: the KR was never really about the file, it was about a reader being able to tell truth from projection, and that need survives. (b) DROP the KR and TASK-199, recording that phase 003 closes with one KR withdrawn by a decision made DURING the phase. Honest, and it makes the phase score mean what it says. (c) Keep both and mark the boundary on a file scheduled for deletion — cheapest to do, hardest to defend. NOTE ON PROCESS: TASK-199 has been left not_started and untouched on purpose. Dropping the row is the visible half of dropping the KR, and doing the visible half first would make the record say the KR FAILED rather than that it was WITHDRAWN. The goals lane owns the edit either way; this ask is the decision, not the write. Full context: handoff/2026-08-29-goals-lane-after-design-013.md | TASK-199 |  | answered 2026-08-29: 决定 2026-08-29（用户拍板，Perry 推荐 a）：选 (a) 重述这条 KR。P003-O2-KR3 改成 ADR-010 能满足的东西 —— 「渲染能区分哪些是投影、哪些是 canonical」。理由：这条 KR 买的从来不是「文件里有标记」这个实现，而是「读者能分辨真相和投影」这个读者可见的属性，而那个需求在新表面上原样成立。TASK-199 因此重定范围而不是作废，phase 003 也不需要记录一条被撤回的 KR。写 KR 是 goals lane 的权，已在 handoff/2026-08-29-goals-lane-after-design-013.md 交接；这条 ask 是决定，不是那次写入。 | 2026-08-29 |
+| USER-908 | May Perry rewrite unpushed local history to repair commit 0d68034? MEASURED 2026-08-29: at that commit, every perry-task write on a project carrying .perry/config.jsonl dies with AttributeError: module 'perry_state' has no attribute 'defaulted_over_a_declaring_table' — bin/perry-task at :6773 calls a function that arrives one commit later. The TASK-213 commit also carries the bin/perry-task half of TASK-095 round 4. Its own message's suite claim is FALSE at that commit. The branch tip was whole and main is whole; only this one commit does not build. It is now in main's history via the 777d021 merge, so a git bisect across the 20 commits after it gets a false 'broken' verdict there. WHY THIS IS AN ASK: .perry/hook.md lists git history rewrites — push --force, --force-with-lease, rebase onto main, tag deletion — as high-stakes operations requiring your explicit authorization. I filed it rather than doing it, and a V4 reviewer endorsed that: 'That reasoning is correct and I endorse it — do not rewrite.' WHAT CHANGED SINCE: origin/main is at 45a355d and local main is at 91e5351, so all 27 commits including this one are UNPUSHED. Nobody has seen this history. That materially lowers the risk the hook rule is written for — the rule protects shared history, and this is not shared yet. OPTIONS. (a) LEAVE IT, and document the bad commit so a future bisect knows to skip it. Zero risk, permanent small cost, and the record keeps an honest scar. (b) REWRITE the unpushed history to move the perry-task hunk into the commit that owns it, then verify every commit in the range builds. My recommendation IF you want a clean history, because unpushed is the only moment this is cheap — after a push it becomes a shared-history rewrite and the answer should be (a) forever. (c) Leave the history and add a test that every commit on main builds standalone, so this class is caught at the next merge rather than by a person. Slower, and it does not fix this commit. My recommendation is (b) THEN (c) — repair it while it is still free, and add the guard so the next one is caught by a machine. But this is your call and I will not touch history without it. | — |  | answered 2026-08-29: 决定 2026-08-29（用户拍板，Perry 推荐 b 然后 c）：授权重写未推送的本地历史修复 0d68034，并加守卫。授权已给出。但执行顺序必须倒过来，理由是测量出来的，不是我改主意：重写 0d68034 会改掉它之后每一个 commit 的 SHA，包括 6c0d041 和 8abd30d —— 而那正是当前四个在飞分支的 merge base（coding/task-050-header-index、coding/task-203-round4、coding/task-095-round6 都在 6c0d041，coding/task-157-kr-declared-once 在 8abd30d），其中三个还在跑。现在重写会让它们的 merge base 消失，把已完成的工作推进一次不必要的 rebase，而这些行正是 phase 003 的 Must-Have。所以：(c) 现在做 —— 一行守卫，让下一次这类问题在合并时被机器抓住；(b) 在四个分支落地之后立刻做，那时 origin/main 仍然在 45a355d，未推送这个便宜窗口还开着。如果在那之前发生了 push，(b) 作废，答案永远变成 (a)：那条 hook 规则保护的是共享历史，一旦共享就不该动。 | 2026-08-29 |
+| USER-909 | perry-decide REISSUES a retired ADR id, and perry-task does not — two tools, one contract, opposite answers. Measured by the TASK-235 agent 2026-08-29: delete ADR-011's file and the next mint hands out 011 again. perry-task purge retires an id through the append-only event log so it is never reissued; perry-decide writes NO events at all, so it has nothing to retire an id with. Worse, before TASK-235 the behaviour was NON-DETERMINISTIC: on main an unrelated write re-rendered the index and the next mint reissued anyway. THE STAKE: an ADR id is an address. ADR-007 is cited by name in ADR-010, in DESIGN-013, in three task rows and in this project's own commit messages. If 011 can name two different decisions, every one of those citations becomes ambiguous the moment an ADR is deleted and a new one minted. This did not matter while nobody deleted ADRs; TASK-235 is the row that made deletion ordinary. THE OPTIONS. (a) RECOMMENDED — perry-decide writes events like every other writer, and an id is retired the way perry-task retires one. This is the answer that makes the two tools agree rather than documenting why they differ, and DESIGN-004's whole posture is that every write goes through a tool and leaves a trace. Cost: perry-decide gains an event surface it does not have today. (b) Refuse the delete instead: an ADR file may not be removed, only superseded — which is arguably what a decision record SHOULD mean, since ADR-005 and ADR-007 are cited as history and history is not deleted. Cheaper, and it may be more correct in principle. (c) Accept reissue, and document that an ADR id is a slot rather than an address. Honest but it silently breaks every existing citation. (d) Leave it declared as it is now — the TASK-235 agent pinned the disagreement with a named test rather than resolving it silently, so nothing is hidden and the row can close. My recommendation is (b) THEN (a): stop the deletion that creates the problem, then give perry-decide the event surface so the two tools stop disagreeing on principle rather than by accident. But (b) changes what a decision record IS, which is yours and not mine. | — |  | pending | 2026-08-29 |

+{"id": "USER-904", "needed": "TASK-050 has now failed SEVEN V4 rounds and needs a decision, not a round 8. Each round's fix moved the same defect rather than closing it: round 5's reviewer defeated a regex, round 6 replaced it with an AST walk, and round 7 showed the walk's gate is still an allowlist of variable names (ROW_NAMES, 11 entries). Measured: of 829 mapping constructs in the 18 readers, 59 are classified as row-cell sources and 35 of those are the bare name 'header'; FOUR LIVE header resolutions (viewer/parsers.py:1827, bin/perry-task:6029 and :6200, bin/perry-tasks:925) can be reverted to the exact historical defect with the whole 2793-test suite green, and parsers.py:1827 silently drops a KR when reverted. In the other direction the check now reports CORRECT code — 6 of 8 legitimate shapes flagged, including the exact latent risk round 5 recorded. Blind to four of the tree's own header resolutions AND loud about a keyword tokenizer: both failure modes the spec names, in one artefact. THE CHOICE. (A) Round 8, same shape — widen the source-expression recognition. The record says this is the fourth time that has moved the defect. (B) Invert the burden: flag EVERY case-folding map in a reader, and require the ~30 legitimate value normalizers to carry a one-line opt-out marker. Correct code declares itself once; anything new is caught by default. Cost: touching 30 live sites and a new convention. (C) RECOMMENDED — make it structurally impossible: one header_index() function becomes the only thing allowed to fold a header, and the guard becomes 'nothing outside it calls squash on a row', which is a one-symbol surface instead of a shape. This is the move ADR-007 already made for stores. (D) Accept the guard as advisory rather than a gate, close the row at a lower rung, and document the limitation. My recommendation is C, with B as the fallback. All four are design decisions with blast radius beyond this row, which is why this is an ask and not a dispatch.

I caused three of the five, and every one is the same shape: two situations answered as one, one step to the left of the last. Round 1 collapsed four None-returns. Round 2 collapsed 'no-track-record' into unusable and hard-blocked three of this repo's own fixtures. Round 3 collapsed the two default cases. Round 4 filtered on the NAME 'main' instead of on whether the table DECLARED it. Round 5 compares on names over records, so a record that CONTRADICTS a declared row counts as carrying it. THE DECISION, and the reviewer states it cleanly: two principles are each defensible applied once, and round 5 applies one to the synthesised main and the other to the recorded main. (A) 'A declared row the register contradicts is drift' — then a table declaring queue/4/3d beside a store recording project must WARN, and perry-lint already computes exactly that. (B) 'The store is truth and the table is a stale projection' — then the trackless case must be SILENT too, because the register answered there as well. Pick one and it applies everywhere; the current code cannot be right because it holds both. SECOND, SEPARATE DECISION — the refusal WIDTH, and it is urgent because I made it worse: I widened the write refusal from source=store-default to source=store, and the reviewer measured three ordinary hand-edit workflows now hard-blocked that wrote at 45a355d AND at round 4. On the third — derive the store from a two-track table, then hand-swap one row — 'perry-config write --from-file', the ONLY command both refusal messages name, exits 1. The block cannot be cleared by the documented remedy. Options: revert to round 4's narrower width; make it a warning rather than a refusal; or fix perry-config so the remedy works. THIRD: the perry-goals half of the guard is a tautology — deleting it leaves the full 2875-test suite at exactly the baseline, which is the same defect TestTheGoalsLaneRefusesToo's own docstring records against round 2. My recommendation: (A) for the principle, because perry-lint already owns that rule and the root cause across three rounds has been re-deriving it differently; plus revert the refusal width to round 4's until perry-config's remedy is fixed.

Measured: a 291-byte 3-record intake.jsonl goes to 0 on 'perry-task add --track ops' with rc 0, byte-identical on 45a355d, and perry-lint reports '0 row(s) drifted'. It is round 1's blocking finding word for word — round 2 closed it for the project-mode track and never asked the queue-mode track, which is the mode ## Intake exists for. Three more doors of the same shape: intake 3->1, ask 3->1, risk-add 3->1, all rc 0, all preserved on base. THE DECISION. (A) Evaluate the gate against the board AS IT WAS AT COMMAND ENTRY, not after the command mutated it — snapshot the shape before any board write. Principled and small, but it is the fourth 'move the question' fix on this row and the first three all looked principled too. (B) RECOMMENDED — make it structurally impossible: an ordinary write may never SHRINK a canonical store. Only an explicit removal command (purge, resolve-intake, intake-sweep) may reduce the record count, and any derivation that would produce fewer records than the store holds is a refusal, not a write. That is one invariant covering every door found in three rounds — the command name, the non-unique tuple, the four section shapes, and the ensure_section ordering — instead of a fourth predicate. (C) Revert TASK-203 entirely and reconsider the row. It has introduced a store-truncation regression in all three rounds; before it, intake.jsonl did not exist and could not be wrong. That is a real 'should we do this at all' question and it deserves an answer, not an assumption. (D) Narrow the scope to the risks register only, which is the one that already existed, and defer intake/asks. NOTE THIS AFFECTS THE PHASE: TASK-203 is the ONLY row under P003-O1-KR1, and DoD Must-Have 2 names intake.jsonl and asks.jsonl explicitly, so (C) or (D) means the phase misses that Must-Have deliberately rather than by accident. Also filed from this round: my third shape test is VACUOUS (the legend table lands under ## Top risks because ensure_section anchors ## Intake before ## P0, so the foreign shape has no test on any register); the uniqueness test cannot distinguish uniqueness from adjacency; load_register_records lets a JSONDecodeError escape as an uncaught traceback where every other failure in that file is a Refused.

+
+> Status: active

+> Deciders: Ran Jiao
+> Supersedes: ADR-007 § 6 decision 2 (that one sentence only)   · Superseded by: —
+> Sunset: —
+
+## Context
+
+ADR-007 § 6 decision 2 asked *"Does `BOARD.md` stop being hand-editable?"* and
+answered *"Yes — it becomes rendered output, and a hand edit becomes drift."* The
+file was kept because a human reads it. That was decided 2026-08-19, and the
+measurement offered before deciding was `drift: 0` on this project.
+
+On 2026-08-29 a census of all 380 markdown files under `perry/` measured what the
+kept projection is actually made of:
+
+- **`BOARD.md` is 43,289 bytes, of which 42,099 — 97% — are inside table rows.**
+  101 rows. The longest single cell is **2,825 bytes**.
+- The 1,190 bytes outside the tables are a title, nine lines of header prose, and
+  eight `##` section headings.
+- The natural language an agent reads is *inside the cells*: `Next action` and
+  `Summary` are paragraphs. That prose is already in `tasks.jsonl`, because the
+  board is rendered from it.
+
+So there is no markdown-only content on this file to preserve. Keeping the
+projection buys one thing — a file you can open — and costs the read-back path
+for 101 rows of typed fields.
+
+That read-back path is where this project's most expensive open work lives:
+**TASK-050** (seven failed V4 rounds on the single rule that a header cell has
+one normalization; round 7 measured four LIVE header resolutions that revert to
+the historical defect with 2,882 tests green), **TASK-067** (the writer can
+destroy the table it writes to and `perry-lint` cannot see it), **TASK-199**
+(two truth models in one file with nothing marking the boundary), and
+**TASK-234** (a row splitter that was the sixth implementation of `split_row`,
+found by a V4 reviewer after five were unified).
+
+ADR-007 § 6 decision 4 already anticipated the direction: *"the readers for
+`BOARD.md`, `OKR.md` and `.perry/config.md` go when those become stores."* What
+it did not say is that the rendered file goes too.
+
+## Options
+
+1. **Keep `BOARD.md` as a rendered projection.** The status quo, and what
+   ADR-007 § 6 decision 2 chose. Costs the table read-back path permanently, for
+   1,190 bytes of content that is not in the store.
+2. **Keep it and mark the boundary between its two truth models** — TASK-199.
+   Reduces confusion, keeps the parser.
+3. **Delete it; the board is what `perry-tasks`/`perry-state` prints.** Removes
+   the file and the reason to parse a board table. Costs: the file you can open,
+   GitHub-web readability, and it makes the CLI render the entire read surface
+   for a 2,825-byte cell.
+
+Option 3 was recommended for **deferral** in DESIGN-013's draft — until the same
+move had been proved on `OKR.md` and `DECISIONS.md`, which are cheaper. The
+recommendation was declined in favour of deciding now.
+
+## Chosen
+
+**Option 3.** `BOARD.md` stops existing. The board is what a command prints, from
+`tasks.jsonl` and `risks.jsonl`.
+
+**Precisely what is superseded: one sentence** — that `BOARD.md` exists as
+rendered output. This does **not** restore hand-editability; it removes the
+artifact, which is a different thing and a further step in the same direction.
+ADR-007's `## Decision` rules 1, 2 and 3 — typed fields belong to Python, prose
+is never parsed, the agent protocol inverts — stand unchanged and are what
+DESIGN-013 § 5.1 extends.
+
+**Gated on the render, not on the decision.** DESIGN-013 § 6 orders
+`DECISIONS.md`, then `OKR.md`, then `BOARD.md`. The `OKR.md` step must report in
+writing on whether the CLI render is a good enough reading surface. If that
+report is negative, the board step stops and returns to DESIGN-013 rather than
+proceeding because the decision was already made.
+
+## Consequences
+
+**The cost, stated plainly: there is no board file to open.** Today a human — or
+an agent, or a GitHub web reader — opens `perry/BOARD.md` and sees the work.
+After this, seeing the work requires running a command. That is a real loss of a
+real property and it is the main argument against.
+
+**The CLI render is a prerequisite, not a follow-up.** A `Next action` of 2,825
+bytes has exactly one readable form once the markdown is gone. `perry-state
+--json` is a payload, not a reading surface.
+
+**Every lane's entrance ritual is rewritten.** `SKILL.md`, `work/SKILL.md`,
+`goals/SKILL.md` and `decide/SKILL.md` all open by reading the board. That cost
+belongs inside the implementing row, not discovered during it.
+
+**What this buys.** The board table read-back path goes, and with it the reason
+TASK-050, TASK-067, TASK-199 and TASK-234 exist in the form they do. Drift
+detection for the board, `render --write` recovery for it, and its half of the
+two-rename canonical pair go with it.
+
+**Two real projects are affected.** gimegime-pmo and PolyForge are markdown-
+canonical or mid-migration. Their path is `perry-migrate`, and ADR-004's
+migrate-once posture still applies — this must not become a second migration for
+a project that already ran one.
+
+## What would reopen this
+
+- The `OKR.md` step reports that a CLI render is a worse reading surface than the
+  markdown it replaced. That is the stated gate and it reopens this before the
+  board is touched.
+- A host where running a command is not available but reading a file is — the
+  decision assumes every Perry surface has a shell.
+- Evidence that the loss of a linkable, web-readable board costs more than the
+  parser did. `drift: 0` was the measurement offered in 2026-08-19; the
+  equivalent here is how often anyone actually opens the file.

Both consequences are recorded in § 4.1 rather than left in the option text.
+
+## 1. Problem
+
+Perry stores typed state in `.jsonl` and renders it into markdown. ADR-007
+decision 2 made `BOARD.md` rendered output and a hand edit to it drift; TASK-092
+did the same for `OKR.md` and `.perry/config.md`. The projection was kept because
+a human reads it.
+
+That decision bought a permanent tax, and on 2026-08-29 a census of every markdown
+file under `perry/` measured what it costs and, more importantly, **what it is
+actually buying**.
+
+### 1.1 · The measurement
+
+| File | bytes | inside table rows | outside | longest cell |
+|---|---|---|---|---|
+| `BOARD.md` | 43,289 | **42,099 (97%)** | 1,190 (2%) | **2,825 B** |
+| `OKR.md` | 12,275 | 6,340 (51%) | 5,935 (48%) | 192 B |
+| `DECISIONS.md` | 1,834 | 1,394 (76%) | 440 | 68 B |
+| `phase/003-storage-code.md` | 13,905 | 2,224 (16%) | 11,681 | 307 B |
+| `phase/003-linkage.md` | 4,923 | 0% table — YAML 3,573 B + prose 1,344 B | | |
+
+Aggregates, for the directories the census must not disturb:
+
+| Directory | files | bytes | table |
+|---|---|---|---|
+| `evidence/` | 325 | 1,929,966 | 8% |
+| `journal/` | 9 | 512,546 | 2% |
+| `design/` | 13 | 297,814 | 24% |
+| `handoff/` | 9 | 102,320 | 11% |
+| `decisions/` (ADR bodies) | 9 | 42,566 | 9% |
+| `weekly/`, `knowledge/` | 3 | 8,929 | **0%** |
+
+### 1.2 · What the numbers say, one file at a time
+
+**`BOARD.md` is 97% table.** The natural language an agent reads is *inside the
+cells* — `Next action` and `Summary` are paragraphs, and the longest single cell
+is 2,825 bytes. Strip the tables and 1,190 bytes remain: a title, nine lines of
+header prose, and eight empty `##` headings.
+
+That prose is **already in `tasks.jsonl`**, because the board is rendered from it.
+So on this file the question "should the tables leave the markdown" has no
+content: there is no markdown-only prose to leave behind. The only coherent
+version of the proposal is *delete the file and render it on demand*, and that
+reverses ADR-007 decision 2, which the user made personally on 2026-08-19.
+
+**`OKR.md` is 51/48 with a longest cell of 192 bytes.** Here the split is real.
+The prose is Mission, Operating Principles, Anti-Goals and the per-objective
+narrative — none of which belongs in a record, and one of which is the rule this
+whole design serves:
+
+> Never compute a number by reading files and eyeballing it. Perry's oldest rule;
+> `bin/perry-state` exists because of it.
+
+The tables are genuinely tabular and `okr.jsonl` already holds 34 KR records and
+2 version records. Dropping the tables from `OKR.md` costs nothing that is not
+recoverable by a command.
+
+**`DECISIONS.md` is a 12-row index that already declares itself a view**, in its
+own third line: *"Rendered by `bin/perry-decide` from `decisions/ADR-*.md`. Those
+files are the record; this file is a view of them … do not hand-edit rows here,
+they are overwritten."* It is a projection whose source is a set of documents
+rather than a store. `perry-decide list` already prints it.
+
+**The `phase/` pair is a genuine duplication with no check** — the same KR id,
+title, metric and target in a markdown table and in a YAML frontmatter, and
+`perry-lint` reports drift for four stores and nothing for this pair. It is
+**out of scope here** and owned by TASK-157, because it is a defect that has
+already produced a wrong number rather than an architecture question.
+
+**Everything under `evidence/`, `journal/`, `design/`, `decisions/`, `handoff/`,
+`weekly/` and `knowledge/` is a document.** `design/`'s 24% is each document's own
+`User Decisions` table — part of that document, not a projection of anything.
+`evidence/` and `journal/` are the record of what happened; rewriting them would
+make the record disagree with itself.
+
+### 1.3 · What the tax actually is
+
+Every markdown table Perry writes must also be **parsed**, and parsing them is
+where this project's most expensive open work lives:
+
+- **TASK-050** — seven failed V4 rounds, on the single rule that a header cell
+  has one normalization. Round 7 measured four LIVE header resolutions that
+  revert to the historical defect with 2,882 tests green.
+- **TASK-067** — the writer can destroy the table it writes to, and `perry-lint`
+  cannot see it.
+- **TASK-199** — `BOARD.md` carries two truth models and nothing marks the boundary.
+- **TASK-234** — `.perry/conformance.md`'s row splitter is the *sixth*
+  implementation of `split_row`, found by a V4 reviewer after five were unified.
+
+Plus the projection machinery itself: the drift concept, `render --write`
+recovery, the two-rename canonical pair and its crash recovery — a large part of
+DESIGN-004.
+
+**None of that tax is paid for prose.** It is paid entirely for reading back
+tables that a store already holds.
+
+## 2. Goals
+
+1. **State a rule that decides where any given fact lives**, so this question is
+   answered once rather than per file.
+2. **Retire the markdown-table read path for the files where the tables are pure
+   projection**, and with it the parsers that exist only to read them back.
+3. **Do not lose the prose.** Mission, principles, anti-goals, narrative,
+   reasoning and history stay in documents, unchanged and un-schematised.
+4. **Prove the pattern on a cheap file before betting the board on it.**
+
+## 3. Non-Goals
+
+1. **Not touching `evidence/`, `journal/`, `design/`, `decisions/`, `handoff/`,
+   `weekly/` or `knowledge/`.** They are documents. The record of what happened
+   is never rewritten.
+2. **Not moving prose into stores.** A 2,825-byte `Next action` is already an
+   awkward JSON field; this design does not make that worse, and a jsonl line
+   carrying a paragraph is a bad diff and a worse read.
+3. **Not the `phase/` duplication** — TASK-157.
+4. **Not `.perry/config.md`** (TASK-233) or `.perry/conformance.md` (TASK-234).
+   Both are decided or filed separately and neither is a document/store split of
+   the kind this design is about.
+
+## 4. User Decisions
+
+| # | Question | Options | Answer | Notes |

+
+### 4.1 · Consequences accepted, 2026-08-29
+
+**D3 went past the recommendation.** The draft recommended keeping `DECISIONS.md`
+as a rendered view, on the ground that its rows are markdown links into
+`decisions/ADR-*.md` and a reader browsing the repository on the web navigates by
+them. The answer is **delete**. The consequence accepted: **that link surface
+goes, and nothing replaces it in the repository itself** — a web reader lands in
+`decisions/` and reads the directory listing. `perry-decide list` is a terminal
+surface and cannot be linked to. This is recorded because it is a real property
+being given up, not an implementation detail; the implementing row must not
+quietly re-add an index to avoid it.
+
+**D4 went past the recommendation.** The draft recommended deferring `BOARD.md`
+until D2 and D3 had run, on three measured grounds: it is 97% table so this is a
+deletion rather than a trim, it supersedes a signed decision, and the CLI render
+becomes the *entire* read surface for a 2,825-byte `Next action`. The answer is
+**do it now, with a superseding ADR**. Two consequences accepted:
+
+1. **The CLI render is a prerequisite, not a follow-up.** The implementation plan
+   in § 6 keeps its order for that reason — `OKR.md` and `DECISIONS.md` still run
+   first, and the render they produce is what the board depends on. What D4
+   changes is that the board is no longer *gated on a decision*; it is gated on
+   the render being good, which is a question of fact.
+2. **Every lane's entrance ritual is rewritten, and that cost is inside the
+   `BOARD.md` row rather than discovered during it.** `SKILL.md`, `work/SKILL.md`,
+   `goals/SKILL.md` and `decide/SKILL.md` all open by reading the board.
+
+**What is NOT superseded, and this correction matters.** ADR-007 § 6 decision 2
+answered *"Does `BOARD.md` stop being hand-editable?"* with *"Yes — it becomes
+rendered output, and a hand edit becomes drift."* D4 does not restore
+hand-editability; it removes the artifact. And ADR-007 § 6 decision 4 already
+said *"the readers for `BOARD.md`, `OKR.md` and `.perry/config.md` go when those
+become stores"* — so this design largely **completes ADR-007's own direction**
+rather than reversing it. The single sentence superseded is that `BOARD.md`
+exists as rendered output. Rules 1, 2 and 3 of ADR-007's `## Decision` stand
+unchanged and are what § 5.1 extends.
+
+## 5. Architecture
+
+### 5.1 · The rule
+
+> **A fact that has a schema lives in exactly one store. A document holds what
+> has no schema. No field lives in both.**
+
+The current architecture violates this in both directions, and naming both is
+the point:
+
+- **Documents hold schema'd fields.** `BOARD.md` carries `Status`, `Track`,
+  `Stage`, `Verification` — every one of them typed in `schema/state-schema.json`
+  and stored in `tasks.jsonl`. That is why drift detection has to exist.
+- **Stores hold unschema'd prose.** `tasks.jsonl`'s `Next action` reaches 2,825
+  bytes of paragraph. That is why a `tasks.jsonl` line is unreadable and its diff
+  is unusable.
+
+The second half is **not fixed by this design** and is called out as a known
+violation (§ 7). Fixing it means giving prose its own home per row, which is a
+bigger change than this document proposes.
+
+### 5.2 · `OKR.md` — the proof
+
+`OKR.md` keeps `## Mission`, `## Operating Principles`, `## Anti-Goals`, the
+per-objective narrative and `## Versioning log`. It stops carrying the KR tables.
+`perry-goals` gains a read-only render — the numbers come from `okr.jsonl`, which
+already holds them.
+
+This is the pattern's cheapest possible test: the tables are small, the cells are
+short (192 B maximum), the store exists, and the file has 5,935 bytes of prose
+that unambiguously belongs to it. If the pattern is wrong, it will be visibly
+wrong here at low cost.
+
+### 5.3 · `DECISIONS.md` — the cheapest cut
+
+Nothing is lost by deleting it. It is 12 rows, no per-row prose, it is generated,
+and its own header tells the user not to edit it. `perry-decide list` is already
+the same content. The one thing to preserve is the **link surface**: the rows are
+markdown links into `decisions/ADR-*.md`, and a reader browsing the repo on the
+web uses them. That is the argument for "keep it as a rendered view" and it is a
+real one — hence the three-way option in Decision 3 rather than a yes/no.
+
+### 5.4 · `BOARD.md` — decided, and gated on the render rather than on a decision
+
+`BOARD.md` stops existing. The surface is a CLI render from `tasks.jsonl` and
+`risks.jsonl`.
+
+The three measured facts that argued for deferring are still true and now become
+requirements rather than reasons to wait:
+
+1. **It is 97% table.** 42,099 of 43,289 bytes are inside table rows, so this is
+   a deletion. The 1,190 bytes outside — the title, nine lines of header prose,
+   eight section headings — are the only thing that could survive as a document,
+   and none of it is worth a file.
+2. **It supersedes ADR-007 § 6 decision 2**, which requires ADR-010 to exist
+   before the row closes. See § 4.1 for what is and is not superseded.
+3. **The render becomes the entire read surface** for a `Next action` that
+   reaches 2,825 bytes. `perry-state --json` is the payload but it is not a
+   reading surface; the render has to be good enough that a human running one
+   command sees what opening the file showed them. Steps 1 and 2 of § 6 exist to
+   build and prove that render on cheaper files first.
+
+### 5.5 · Alternatives considered
+
+- **Keep everything, add reconciles.** This is the status quo plus more checking.
+  Rejected as the default because it grows the parser surface that TASK-050 has
+  failed seven rounds against; but it is the honest fallback if Decision 1 is
+  rejected.
+- **Move prose into the stores and delete all markdown.** Rejected: § 5.1's
+  second violation says a store is already a bad home for a paragraph, and this
+  makes every document one.
+- **Split by file rather than by field** — "these files are stores, those are
+  documents". This is what the design actually proposes; the rule in § 5.1 is
+  what makes the split decidable instead of per-file taste.
+
+### 5.6 · Blast radius
+
+`OKR.md`: `bin/perry-goals`, `viewer/parsers.py`'s OKR reader, `goals/SKILL.md`
+and any lane that reads the KR table for a snapshot.
+`DECISIONS.md`: `bin/perry-decide`, one reader, `SKILL.md` references.
+`BOARD.md`: every lane, `SKILL.md`, `work/SKILL.md`, `reference/adoption.md`, and
+the entrance ritual of every session — which is exactly why it is deferred.
+
+## 6. Implementation plan
+
+Ordered, and each step gates the next. All three are decided; the order is a
+dependency chain, not a series of open questions.
+
+1. **`DECISIONS.md`** (D3 — delete). Smallest surface, one reader, one writer.
+   `perry-decide list` is the surface. The lost link surface is accepted in
+   § 4.1 and must not be quietly re-added.
+2. **`OKR.md`** (D2 — drop the KR tables). `perry-goals` renders them from
+   `okr.jsonl`. The row must **report on whether the CLI render is a good enough
+   read surface**, in writing. That report is step 3's input and the reason this
+   step comes first.
+3. **`BOARD.md`** (D4 — delete, with ADR-010). Runs after 1 and 2, and after
+   ADR-010 is minted. Includes rewriting the entrance ritual in `SKILL.md`,
+   `work/SKILL.md`, `goals/SKILL.md` and `decide/SKILL.md`.
+
+## 7. Risks & mitigations
+
+| Risk | Mitigation |
+|---|---|
+| The CLI render is worse than the markdown and nobody says so until the board is gone | **This is the main risk now that D4 is decided.** Steps 1 and 2 still run first and step 2 must report on read quality IN WRITING. Step 3 is gated on that report being affirmative — if it is not, step 3 stops and comes back here, rather than proceeding because the decision was already made. |
+| Losing web/GitHub readability of a linkable artefact | **Accepted, not mitigated.** D3 chose deletion over a rendered view, and D4 removes the board. § 4.1 records what is given up. The mitigation that was available — keep a generated index — was declined, and the implementing rows must not re-add it to make the loss go away. |
+| **The known violation this design does not fix**: stores hold unschema'd prose (`Next action`, 2,825 B) | Named here rather than left implicit. It gets worse in relative terms once markdown is gone, because the store becomes the only home. A follow-up row, not this design. |
+| An agent's read path changes from "read one file" to "run a query" | `perry-state --json` is already that payload. But every lane's `SKILL.md` opens by reading the board, and step 3 must rewrite that ritual — counted as part of step 3's cost, not discovered during it. |
+| Reversing a signed decision by accident | Decision 4 is worded as an explicit supersede of ADR-007 decision 2 and cannot be answered "yes" without minting that ADR. |
+
+## 8. Open questions
+
+1. Does the `Next action` prose problem (§ 5.1, second violation) deserve its own
+   design, or is it a task row? It is the reason `tasks.jsonl` diffs are unusable
+   today, independent of anything here.
+2. `phase/00N-linkage.md` is YAML frontmatter with no table and 27-46% prose,
+   machine-written and machine-read. Under § 5.1's rule it is a store with the
+   wrong extension. TASK-157 touches it; whether it should be renamed is not
+   asked there.
+
+## 9. Changes (append-only after lock)
+
+**2026-08-29 · Step 2 gains a precondition it did not know it had.**
+
+Reviewing the open rows against this design found `TASK-182` — DESIGN-009 step 2,
+*"`perry-okr render` reproduces `OKR.md` byte-for-byte with objective rows in the
+store"*. It was first read here as a **conflict**, on the ground that it builds a
+renderer for tables this design deletes. That reading was wrong and the
+correction matters, because it reverses the ordering.
+
+DESIGN-009 § 6 states step 2's purpose in its own words: *"**This is the gate**:
+if the renderer cannot rebuild the five headings from records, the records are
+wrong. Same bar as `risks-diff`."* It is a **completeness proof for the store**,
+not a deliverable renderer — and under this design that proof stops being
+incidental and becomes load-bearing. **The KR tables must not be deleted until
+something has proved `okr.jsonl` holds them.**
+
+The risk runs the other way from the one first suspected: **if the `OKR.md` step
+ran first, `TASK-182`'s gate would evaporate.** With the tables already gone there
+is nothing left to rebuild, so the proof would pass vacuously and nobody would
+learn whether the store was complete. That is the defect class this project has
+caught six times — a check that cannot fail on the thing it names.
+
+`TASK-236` therefore depends on `TASK-181` and `TASK-182` as well as `TASK-235`.
+§ 6 step 2's ordering is unchanged; what changed is that it now has an explicit
+precondition rather than an assumed one.

+# The fork Tier A ran into: `perry-migrate` cannot survive it
+
+> Escalation for `TASK-261`, written the way `work/reference/review.md § 6`
+> asks — both readings defensible applied consistently, what is already true,
+> and a named recommendation with its reason.
+
+## What is already true
+
+The ADR-004 gate and its ledger are out. 40 files, **−5,245 lines**. The suite
+is green except `test_migrate` (22 failures, 9 errors) and the three modules
+that are already red on a clean `git archive HEAD` export.
+
+`bin/perry-migrate` calls `C.declare` at **14 sites**. Its *output* is a
+conformance record carrying `route: migrate`. It cannot be repaired without
+restoring the ledger, because the ledger is the thing it writes. Migration and
+conformance were never two subsystems — the delete list called them Tier A and
+Tier C, and that was wrong.
+
+## Reading A — migration is speculation; delete it
+
+`.perry/conformance.jsonl` held 23 records and **not one carried
+`route: migrate`**. `TASK-097` — "migrate the two real projects, at V5" — has
+been `not_started` since the day it was filed. A 2,393-line lossless,
+dry-runnable, recoverable migrator has never moved a single foreign project.
+
+Applied consistently: Perry is a tool for projects it starts. Adoption means
+"run Perry here and let it write its own state". `TASK-097` is dropped along
+with `tests/test_migrate.py` (2,900 lines). Tier C's migration half lands now
+rather than later, and Tier A's total goes past 10,000 lines.
+
+## Reading B — migration is the unbuilt half; keep it
+
+Perry has never been pointed at a foreign project because that work was never
+done, not because it is unwanted. The delete list's own note says the gate's
+value *needs* a foreign project — which is an argument that the missing thing
+is the project, not the mechanism.
+
+Applied consistently: the ledger comes back for `perry-migrate` alone —
+`declare`, `migrate_record`, `record_diff`, roughly 200 of the 598 deleted
+lines. The **write-path gate stays deleted**. `TASK-097` becomes the next real
+phase. This keeps the option and pays ~200 lines plus `test_migrate` for it.
+
+## Recommendation: A
+
+Not for the line count. Under B the ledger comes back to serve a consumer that
+has never run — so the same measurement that justified deleting it will justify
+deleting it again in three months, and the second deletion will cost what this
+one cost.
+
+If you want Perry to run on other people's projects, the cheap version is an
+**importer you re-run**: read a foreign board, write Perry state, overwrite on
+conflict. That is a smaller thing to build than what Reading B keeps, and it
+has no declaration format of its own to drift.
+
+## Not on the table either way
+
+The write-path conformance gate does not come back. Nothing in this fork
+reopens it.

+The 14 rows kicked back two or more times, with their subject:
+

+
+- **11 rounds** — `TASK-050`, header-cell normalization: md table parsing
+- **6 rounds** — `TASK-095`, remove the parser for three stores
+- **5 rounds** — `TASK-203`, an ordinary write does not update its store: dual write
+- **5 rounds** — `TASK-234`, `.perry/conformance.md` is a hand-rolled table parser
+- **4 rounds** — `TASK-249`, `tests/run` writes Perry state: intake dual write
+- **2–4 rounds each** — `TASK-089`, `093`, `067`, `091`, `241`, `233`, `044`,
+  `042`, `019`, `020`, `027`, `028`: dual write, drift, md parsing, migration
+
+**Not one is about OKR or task management as a domain.** All of them are about
+markdown-as-canonical, its parsers, its drift detection, or its conformance
+ledger.
+
+The three gates that exist to service that architecture, measured on this
+repository's own history:
+
+**drift** — `perry-lint` reports `0 row(s) drifted` on all six stores and
+always has. Every non-zero reading anywhere in this repo comes from a V4
+reviewer deliberately corrupting a store to demonstrate a bug. It has caught
+zero real incidents, and it generated TASK-031, 067, 093, 203 and 243. It is
+still evadable: TASK-243, filed 2026-08-30 — *"a count-preserving substitution
+destroys canonical records silently, and the drift report goes DOWN as it
+happens."* It guards a behaviour `AGENTS.md` already forbids and no agent
+performs.
+
+**the ADR-004 conformance gate** — `.perry/conformance.jsonl` holds 23 records.
+All 23 are `route: declare`. All 23 are Perry's own files. **Zero migrations,
+zero disagreements.** Its entire value proposition is that a stored declaration
+and a live shape check *can disagree, and that disagreement is a finding*. That
+requires a foreign project that drifts, and Perry has never been run on one.
+
+**lint** — today: 0 errors, 4 warnings, and all four are `NS-01` on files you
+deliberately put in `phase/`, `evidence/`, `handoff/` and `knowledge/`. Live
+signal-to-noise 0:4. Its schema half is the part that works and is not on this
+list.
+
+## The list is ordered, because two targets are load-bearing today
+
+`perry_md_store.py` is not a drift helper. `perry-goals` and `perry-config`
+call `md_store.derive`, `md_store.render` and `md_store.store_text` on the real
+write path. `perry-conform` is imported by `perry-task` as a live gate. Neither
+can be deleted before the read/write side stops going through markdown, which
+is what phase 003 Objective 2 and TASK-236/237 are for.
+
+So: three tiers, each with a precondition that can be checked.
+
+---
+
+## Tier A — deletable now
+
+**Precondition: none.** Nothing computes a different answer without these.
+
+| target | lines | note |
+|---|---|---|
+| `bin/perry-conform` | 974 | the ADR-004 declaration gate |
+| `perry_conform()` + the write-gate in `bin/perry-task` | ~60 | `bin/perry-task:6897–6920` and its call sites |
+| `.perry/conformance.jsonl`, `.perry/conformance.md` | 23 records | |
+| `tests/test_conformance.py` | 2,882 | |
+| `tests/mutate_task_234.py` | 568 | |
+| open rows TASK-223, 246, 248 | — | all three are defects *in* the gate |
+
+**≈ 4,500 lines, and three open rows close as `dropped` rather than `done`.**
+
+> **Do not confuse two things called conformance.** This deletes the ADR-004
+> *file declaration* gate. It does **not** touch the `conformance.*` fields in
+> `perry-task list --json` (`evidence_not_found`, `depends_on_unknown`,
+> `blocked_by_closed_rows`, …) — those are read-time integrity reporting, they
+> are a published contract in `schema/task-list-contract.md`, and they are
+> useful. Deleting them would be a real regression.
+
+---
+
+## Tier B — after phase 003 Objective 2 lands
+
+**Precondition:** no code path reads a rendered markdown file as authority.
+Checkable: `P003-O2-KR1`'s four `parse_tracks` call sites move to
+`.perry/config.jsonl`, and `perry-goals` stops deriving from `OKR.md`.
+
+| target | lines |
+|---|---|
+| `check_store_drift` + `_empty_store_drift_stats` | 244 |
+| `check_risk_store_drift` + helper | 149 |
+| `check_intake_store_drift` + helper | 123 |
+| `check_ask_store_drift` + helper | 149 |
+| `check_md_store_drift` + two helpers | 164 |
+| `_order_drift` | 49 |
+| the six census report lines in the default pass | ~40 |
+| `tests/test_store_drift.py` | 966 |
+| the drift halves of `test_risks_store` / `test_asks_store` / `test_okr_store_is_the_source` / `test_register_substitution` | ~1,200 |
+
+**≈ 3,100 lines.** Drift only has a job while a rendered file can be authority.
+When nothing reads one, a hand edit is a no-op, not a hazard — and the check
+becomes a check on a file nobody consults.
+
+---
+
+## Tier C — after TASK-236 and TASK-237
+
+**Precondition:** `OKR.md` and `BOARD.md` stop existing as parsed files and
+become what a command prints. Both rows are already on the board.
+
+| target | lines |
+|---|---|
+| `bin/perry_md_store.py` | 1,203 |
+| `bin/perry-migrate` | 2,393 |
+| `tests/test_md_store.py` | 1,277 |
+| `tests/test_migrate.py` | 2,900 |
+| `tests/test_one_header_rule.py` | 327 |
+| `tests/test_header_index_is_the_only_fold.py` | 775 |
+| `tests/test_store_is_canonical.py` | 356 |
+| `tests/test_last_updated_header.py` | 160 |
+| `tests/test_stranded_rows.py` | 757 |
+| remaining rows TASK-095, 067, 199, 246, 247, 252 | — |
+
+**≈ 10,100 lines.**
+
+> Migration deserves its own argument. `perry-migrate` exists to move somebody
+> else's project onto Perry's shape. **It has never done that** — the
+> conformance log's 23 records carry zero `route: migrate`. TASK-097 ("migrate
+> the two real projects, at V5") has been `not_started` throughout. If the
+> answer to "have we ever migrated a foreign project" stays no, migration is a
+> feature written entirely on speculation, and the cheap replacement for a
+> personal tool is an importer you re-run, not a lossless recoverable
+> dry-runnable migrator.
+
+---
+
+## What it adds up to
+
+| | product code | tests |
+|---|---|---|
+| Tier A | ~1,030 | ~3,450 |
+| Tier B | ~920 | ~2,170 |
+| Tier C | ~3,600 | ~6,550 |
+| **total** | **~5,550** | **~12,170** |
+
+Against today's `bin/` at 33,413 lines and `tests/` at 69,371, that is **17% of
+the product code and 18% of the tests** — and it is the 17% that produced 11 of
+the 14 high-rework rows.
+
+The second-order effect is larger than the line count. **21 of the 69 open rows
+on this board are representation-layer.** Tiers A–C close or drop 9 of them
+outright, and the rest stop generating successors.
+
+## What this list does not propose
+
+- **Not a rewrite.** The asset is the prose — the lane split, what V1–V6 mean,
+  the hand-off contract, "an agent cannot self-award its own rung". None of it
+  is in the code being deleted.
+- **Not touching `perry-lint`'s schema pass.** That half works.
+- **Not touching `perry-task list --json`'s `conformance.*` payload.** See the
+  Tier A note.
+- **Not deciding TASK-097.** Whether Perry is ever pointed at a foreign project
+  is a product question, and it is the one that decides Tier C's migration half.
+  It should be answered by a person, not derived from this list.
+
+## The one thing to check before filing any of this
+
+Tier A rests on a claim that is falsifiable in one command:
+
+```
+grep -c '"route": *"migrate"' .perry/conformance.jsonl     # expected: 0
+```
+

+# TASK-050 round 10 — result
+
+> Branch `coding/task-050-header-index`, forked from `main` at `6c0d041`.
+> Written against `perry/evidence/2026-08/TASK-050-spec.md § Amendment
+> 2026-08-29 — USER-904, option C`, which binds.
+>
+> **This document supersedes `TASK-050-round9-result.md` for everything it
+> restates.** Round 9's result is NOT retracted — its review ruled its core
+> correct — so it stays in place as the record of what round 9 did, with a
+> pointer here and two corrections made in place — the `ROW_NAMES` count (§ 4.3)
+> and § 6.2's `bin/perry-tasks` limit, now closed (§ 4.1). There is one result
+> of record and it is this one.
+
+Round 9's review was a FAIL and mostly a vindication. It ruled for the round on
+the question the round turned on — **0 of 41 on `SECOND_RULE` is ACCEPTABLE
+under option C** — verified the deletion of every variable-name allowlist,
+re-enumerated all 39 `squash`/`norm` call sites by its own AST walk and found no
+third live one, reproduced all ten mutations, rebuilt the corpus independently
+and found no pruning, and confirmed the argument for deleting the shape net by
+planting round 8's own declared false positive.
+
+It failed the round on the **corollary of that vindication**: with the shape net
+gone, the drift half carries the whole static claim, and the drift half
+recognised the one rule by the **function's name** rather than by the symbol.
+
+**Round 10 is that five-line gap, closed, plus the three minor findings and the
+two green mutations that closing it exposed.** No production code changed:
+`git diff --stat b5e7be3 HEAD -- bin/ viewer/ schema/ templates/` is empty, and
+the code diff is three files, all under `tests/` — 366 insertions, 13
+deletions. The rest of the diff is this document and round 9's two inline
+corrections.
+
+---
+
+## 0. What changed, in one list
+
+| # | change | why |
+|---|---|---|
+| 1 | `_RowLocals` resolves a **direct alias binding** — bare assignment, `from … import … as`, attribute access — to a fixpoint; `_blessed_calls` and the scalar half ask the file's own resolved sets | round 9 review, the FAIL: `fold = squash` walks past a check stated over the spelling |
+| 2 | corpus `D25`–`D33`, nine entries, each quoting the review line it comes from | the corpus planted both HARDER indirections and neither easy one |
+| 3 | `_plant` stops prepending a shebang to `D20` and `S12`; `NO_SHEBANG` and a new auditability test | round 9 review, minor 1: `D20` could not discriminate the hole it names |
+| 4 | `Watch.__enter__`'s rebinding loop is **kept and given a test** | round 9 review, minor 2: it survived its own deletion with all 7 tests green |
+| 5 | `bin/perry-tasks` is **driven** by the runtime watch (`cmd_intake_write`), and added to `WATCHED` | round 9 § 6.2's own declared limit, and the file the reviewer planted its escape into for exactly that reason |
+| 6 | `D30` re-planted out of order; `D32`/`D33` added | two of this round's own mutations came back GREEN — § 3.2 |
+
+---
+
+## 1. The FAIL, closed — the guard is now over the SYMBOL
+
+### 1.1 What escaped, reproduced first
+
+The reviewer's probe, replayed on `b5e7be3` before touching anything
+(`scratchpad/r10/probe_alias.py`, one plant at a time into a copy, every body
+`[fold(c) for c in split_row(line)]`, control included):
+
+```
+CAUGHT  A  fold = lambda s: squash(s)   (== corpus D10)
+ESCAPED B  fold = squash
+ESCAPED C  fold = squash, SCALAR on a cell
+CAUGHT  D  def fold(s): return squash(s)  (== corpus D09)
+ESCAPED E  from tables import squash as fold
+ESCAPED F  import tables; fold = tables.squash
+ESCAPED G  the repo's OWN idiom renamed: keyof = squash
+CAUGHT  H  CONTROL: plain squash
+ESCAPED I  transitive: a = squash; fold = a
+ESCAPED J  function-local alias inside the reader
+```
+
+Reproduced exactly, including the two the reviewer recorded without charging.
+The two *harder* indirections were resolved and the one-liner was not, and
+**why** is worth stating: `def fold(s): return squash(s)` and `fold = lambda s:
+squash(s)` are caught not by the alias machinery but by parameter
+provenance — the row cell reaches the wrapper's parameter, so `squash(s)`
+inside it is a scalar fold of a cell. A bare `fold = squash` has no body for a
+cell to reach.
+
+### 1.2 The fix
+
+`_RowLocals` now builds `self.aliases: dict[str, str]` — *local name → the
+BLESSED name it IS* — from three binding shapes, run to a fixpoint, and exposes
+two per-file frozensets:
+
+- `rows.blessed` = `BLESSED` ∪ every name this file bound to one of them;
+- `rows.rule` = `THE_RULE` ∪ every name this file bound to `squash`/`norm`.
+
+`_blessed_calls(elt, rows.blessed)` and `name in rows.rule` replace the module
+constants at the four sites that asked them.
+
+**This is not a list of names.** A name is in `aliases` because a binding in
+*this file* put the blessed function object in it, and for no other reason —
+the same standard `by_name` already meets for `def` and `lambda`. File-wide
+rather than per-function, because an import binds at module level and is called
+from every function in the file.
+
+Deliberately **not** resolved, and recorded as a limit in § 6 rather than
+widened: a rebinding through a container (`FOLDS["k"] = squash`), a function
+that *returns* the rule, and a binding made in another module.
+
+### 1.3 After
+
+All ten probe cases now resolve as they should, and both clean controls stay
+silent:
+
+```
+CAUGHT  A B C D E F G H I J
+ESCAPED K  alias of a NON-rule name (tidy = str.strip) used on a row
+ESCAPED L  alias of the rule used as a VALUE normalizer, not on a row
+```
+
+`K` and `L` are the criterion-4 half of the same change and they are why it is
+stated over the *binding* and not over the *name*.
+
+### 1.4 On the live tree, nothing moved
+
+```
+$ offenders_by_symbol('.')  ->  []
+$ every alias in the whole tree:
+  bin/perry-lint  {'norm': 'squash'}
+```
+
+**One alias exists in this repository and it was already blessed.** That is the
+point of the finding: `bin/perry-lint:250` is literally `norm = squash`, and it
+was seen only because `norm` happens to sit in `BLESSED`.
+
+---
+
+## 2. The live demonstration — the repository's own idiom, renamed
+
+`R10-11`, on `bin/perry-lint` itself, two sites, anchored and asserted on the
+exact old text (`scratchpad/r10/mutate_lint.py`):
+
+```
+bin/perry-lint:250   norm = squash            +  keyof = squash
+bin/perry-lint:348   value = key              ->  value = keyof(key)
+```
+
+That is R9-1's site with one difference: the alias is spelled with an
+untrusted name.
+
+```
+baseline: both targets GREEN
+test_one_header_rule                    RED: test_nothing_outside_header_index_maps_squash_across_a_row
+                                             test_value_normalizers_are_not_flagged
+test_the_static_net_is_the_one_that_sees_dead_code   RED
+offenders_by_symbol -> ['bin/perry-lint:349: keyof(key)']
+restore md5 OK  e1c277b2336f22b6ed490c8205fd2f0f   tree after restore: clean
+```
+
+Counter-check, the same plant against round 9's own `tests/header_rule.py`
+(`git archive b5e7be3`):
+
+```
+round 9 header_rule, same plant -> []  <-- ESCAPED
+```
+
+Caught here, silent there, on a live reader.
+
+---
+
+## 3. Mutations — eleven, each anchored by line and asserted on the old text
+
+Harness: `scratchpad/r10/mutate.py`. It **refuses a dirty tree**, **asserts the
+target test is GREEN before mutating**, clears `__pycache__`, waits past the
+whole-second boundary, restores the whole file and verifies `md5` plus a clean
+`git status`. Round 9's reviewer confirmed that discipline is why round 9's
+hand restore was clean; it is unchanged.
+
+### 3.1 The nine that reddened a named test
+
+| # | site | target | RED |
+|---|---|---|---|
+| R10-1 | `header_rule.py:337` `a.name in BLESSED` → `in ()` | `test_each_drift_shape_is_caught` | **`D26`** only |
+| R10-2 | `header_rule.py:342` `target = self._alias_target(…)` → `None` | same | **`D25` `D27` `D28` `D29` `D30` `D31`** |
+| R10-3 | `header_rule.py:310` `name = value.attr` → `return None` | same | **`D27`** only |
+| R10-4 | `header_rule.py:332` fixpoint `range(4)` → `range(1)` | same | **`D30`** only |
+| R10-5 | `header_rule.py:584` `rows.blessed` → `BLESSED` | same | **`D32` `D33`** |
+| R10-6 | `header_rule.py:611` `rows.rule` → `THE_RULE` | same | **`D28`** only |
+| R10-7 | `header_rule.py:132` `is_python` back to round 8's (`suffix ⇒ .py`, else shebang) | same | **`D20` AND `D21`** |
+| R10-8 | `test_header_rule_harness.py:84` `NO_SHEBANG` → `frozenset()` | `test_the_no_shebang_entries_are_planted_without_one` | RED |
+| R10-9 | `test_header_index_is_the_only_fold.py:213` `for attr in ("squash","norm")` → `for attr in ()` | `test_header_index_is_the_only_fold.py` | `test_the_rebinding_loop_watches_a_readers_own_reference` |
+
+**The three alias forms the brief names, each pinned to its own mutation:**
+`fold = squash` → R10-2 (`D25`); `from tables import squash as fold` → R10-1
+(`D26`, and *only* `D26`); `import tables; fold = tables.squash` → R10-3
+(`D27`, and *only* `D27`).
+
+**R10-7 is the D20 regression check the brief asked for.** Round 9's R9-6
+reddened `D21` and **not** `D20`, which was the reviewer's proof that the entry
+could not discriminate. The same mutation now reddens both. The problem is
+closed, not moved.
+
+### 3.2 The two that came back GREEN, and what they cost
+
+Both were run before the entries below existed, and both are reported because a
+green mutation is the finding.
+
+- **R10-4 was GREEN.** `D30`'s alias chain (`a = squash; fold = a`) was written
+  in order, and `ast.walk` is breadth-first, so one pass already resolves it —
+  the fixpoint was dead weight the corpus could not see. `D30` is re-planted
+  with its first link nested inside an `if`, which reverses the order the walk
+  reaches the two links in and is valid Python. R10-4 then reddens `D30` and
+  only `D30`.
+- **R10-5 was GREEN.** Every alias entry in the corpus was *redundantly* caught
+  by the scalar half, because an alias inside a comprehension is a `Call` node.
+  `D32` (`map(fold, row)`) and `D33` (`sorted(key=fold)`) pass the alias
+  without calling it, so the mapping half is the only thing that can see them.
+  R10-5 then reddens exactly those two.
+
+### 3.3 R10-10 — the reviewer's own end-to-end plant, replayed verbatim
+
+`scratchpad/r10/mutate_tasks.py`, the two sites exactly as the round 9 review
+states them:
+
+```
+bin/perry-tasks:80   from tables import header_index, squash   +  _fold = squash
+bin/perry-tasks:926  keys = header_index(perry_store.intake_table(board, ops)["header"],
+                                         alias=ops.norm)
+                  -> _hdr = perry_store.intake_table(board, ops)["header"]
+                     keys = [ops.norm(_fold(c)) for c in _hdr]
+```
+
+```
+baseline: both targets GREEN
+test_every_fold_of_a_header_cell_came_from_header_index   RED
+test_one_header_rule                                      RED: NOTHING
+offenders_by_symbol (the STATIC half) -> []
+restore md5 OK  4a8ce792a8ce15d24b49f182c53da431   tree after restore: clean
+```
+
+**Read that second and third line, because they are the honest part of this
+round.**
+
+---
+
+## 4. What the reviewer's end-to-end case actually was, and it was not only the alias
+
+The round 9 review's prescribed fix — *"resolve module-level `NAME = <blessed>`
+and `from tables import squash as NAME` bindings into the blessed set … then add
+B/E/F to `DRIFT`"* — is implemented in full, and **it does not close the
+reviewer's `bin/perry-tasks` demonstration.** Measured, not argued:
+
+```
+$ # round 10 tree, the reviewer's plant, static half only
+offenders_by_symbol('bin/perry-tasks') -> []
+```
+
+The reason is not the alias. It is `_hdr`:
+
+```python
+_hdr = perry_store.intake_table(board, ops)["header"]
+```
+
+`intake_table` lives in **another module** and the row is carried through a
+**dict key** (`perry_store.markdown_tables` builds `{"header": split_row(…), …}`).
+`_RowLocals` is file-local by construction, so `_hdr` is not a row to it — with
+or without the alias. The same plant written with a bare `squash` escapes round
+9's tree identically, which is the proof the two holes are independent:
+
+```
+$ round 9's own header_rule, `[squash(c) for c in _hdr]`, no alias at all
+ESCAPED
+```
+
+**Closing that statically would be interprocedural row-source recognition
+across module and dict boundaries — the widening the amendment rejects by
+name** ("Option A, widening the source-expression recognition for an eighth
+round"). So it is not closed statically, and the design's own answer is used
+instead.
+
+### 4.1 `bin/perry-tasks` is now driven
+
+Round 9 § 6.2 declared it: *"`bin/perry-tasks` is converted and not driven."*
+The reviewer planted there for exactly that reason. `cmd_intake_write(root,
+["--from-board"])` now runs **in process** inside `Watch`, against a throwaway
+root carrying a `**Arrived**` intake header, and `cmd_intake_write` is added to
+`WATCHED` so the claim is asserted rather than listed. The driver asserts `rc ==
+0` and that the store was written, so a refusal cannot pass as coverage.
+
+Under the plant, `_fold("**Arrived**")` is called straight from
+`cmd_intake_write` with no `header_index` in the stack, and
+`test_every_fold_of_a_header_cell_came_from_header_index` goes **RED**. That is
+a named test, and it is the half of the design that is blind to spelling
+altogether.
+
+### 4.2 So what covers what
+
+| the shape | seen by | how |
+|---|---|---|
+| the rule applied to a row a **local** dataflow reaches, under any alias | `offenders_by_symbol` | § 1, § 2 — statically, in dead code too |
+| the rule applied to a row a **cross-module** call produced | `test_header_index_is_the_only_fold` | § 4.1 — at runtime, if a parse reaches it |
+| a reader that invents its **own** rule | `test_every_decorated_header_cell_reached_header_index` | it stops reaching `header_index` |
+
+The reviewer's ruling on the third row is carried rather than re-derived, and it
+is measured rather than argued: reverting `viewer/parsers.py:1833` reddens
+`test_every_decorated_header_cell_reached_header_index`, and so did the
+reviewer's own **value-identical** alias fold at the same site, reporting
+`missing: ['due', 'kr']`. That is what makes 0 of 41 a stated limit and not a
+hole.
+
+### 4.3 The correction to round 9's result
+
+`grep -rn "ROW_NAMES" tests/ bin/ viewer/` returns **two** prose lines, not the
+four round 9's result claims. Both are prose saying the set was deleted; there
+is no code. The load-bearing half of the sentence was true and the count was
+wrong. Corrected in `TASK-050-round9-result.md` in place, so the two documents
+do not disagree.
+
+---
+
+## 5. The corpus and the three fractions
+
+`python3 -c "import test_header_rule_harness as H; print(H.measure())"` on this
+tree:
+
+```
+{'drift_escaped': [], 'clean_flagged': [], 'second_rule_caught': []}
+DRIFT 33   CLEAN 12   SECOND_RULE 41   UNRECOVERABLE 2
+```
+
+| corpus | size | result |
+|---|---|---|
+| `DRIFT` — must all be caught | **33** (was 24) | **33 of 33 caught** |
+| `CLEAN` — criterion 4, must all be silent | **12** | **0 of 12 flagged** |
+| `SECOND_RULE` — the declared limit, asserted to escape | **41** (+2 unrecoverable) | **0 of 41 caught** |
+
+The nine new `DRIFT` entries and their provenance:
+
+| entry | shape | source |
+|---|---|---|
+| `D25` | `fold = squash` | round 9 review, ESCAPED B |
+| `D26` | `from tables import squash as fold` | round 9 review, ESCAPED E — the case `D06` does not cover, because `D06` aliases onto `norm`, a name already in `BLESSED` |
+| `D27` | `fold = tables.squash` | round 9 review, ESCAPED F |
+| `D28` | bare alias applied to ONE CELL | round 9 review, ESCAPED C |
+| `D29` | `keyof = squash`, the repo's own idiom renamed | round 9 review, ESCAPED G |
+| `D30` | a chain of aliases, bound OUT OF ORDER | round 9 review's prescribed fix + this round's R10-4 |
+| `D31` | an alias bound inside the reader | round 9 review, and a rebinding is not obliged to sit at module level |
+| `D32` | `map(fold, row)` — alias never CALLED | this round's R10-5 |
+| `D33` | `sorted(key=fold)` — alias never CALLED | round 7 Finding 2, planted for an alias |
+
+`0 of 41` is unchanged and is the same declared limit round 9's review ruled
+ACCEPTABLE, for the reason it gave: detecting a from-scratch fold *is* source-
+expression recognition, so failing the row on it orders the option the
+amendment rejects by name. R9-9 reproduces — the row inference that would raise
+that number is the same inference that reports `C06` — so 41-of-41 and 0-of-12
+cannot both be had.
+
+---
+
+## 6. Baselines — runner AND tree, every one measured here
+
+| runner | tree | modules | tests | failures |
+|---|---|---|---|---|
+| `bash tests/run` | round 10 code tip `a1ff426`, on a `git archive` export | **99** | **2897** | **3** |
+| `bash tests/run` | round 10 `HEAD` = `22f0cfc` (docs on top), same method | **99** | **2897** | **3** |
+| `bash tests/run` | `main` @ `3c7c8ba`, on a `git archive` export | 101 | 3019 | 3 |
+| `python3 -m unittest discover -s tests` | round 10 `HEAD`, same export | — | **2897** | **6** |
+
+The three under `bash tests/run` are identical on both trees and are the three
+this row has carried since round 8:
+
+```
+test_diagnose.DecisionsAreCountedPerRecordNotPerMention
+    .test_the_queue_register_reconciles_with_the_queue_on_this_repository
+test_diagnose.TestUserLoadFindings.test_perry_itself_passes_its_own_id_checks
+test_kr_progress_provenance.TestBothOfTodaysWrongReadingsFlip
+    .test_no_current_in_the_payload_claims_to_be_a_measurement
+```
+
+`discover` is exactly 3 more, and the three extra are the
+`test_risks_store.TestTheReadersAreOneFunction` double-import artefact round 9's
+reviewer corroborated independently and measured `OK` in isolation. That closes
+the last carried figure on this row.
+
+**`+2` over round 9's 99 / 2895 / 3** is `test_the_no_shebang_entries_are_planted
+_without_one` and `test_the_rebinding_loop_watches_a_readers_own_reference`.
+Nothing else moved.
+
+**`main` has moved and this branch has not been rebased.** Round 9 was reviewed
+against `main` @ `6c0d041` (98 / 2882 / 3); `main` is now `3c7c8ba` at 101 /
+3019 / 3 — 3 modules and 137 tests this branch has never seen. The failure set
+is the same three on both, so nothing here is hidden by the gap, but the merge
+is a real one and is named in § 7.
+
+**Call sites: 59, unchanged.** Counted by AST (`ast.Call` whose callee is
+`header_index` or `header_keys`) over `readers_under(.)`. No reader was
+converted this round.
+
+**The worktree matches its commit.** Every tracked blob re-hashed against
+`git ls-tree -r HEAD`: **689 files checked, 0 mismatches**; `git status
+--porcelain` empty and `git ls-files -o --exclude-standard` empty. Eleven
+mutations were applied to this tree and every one restored under an `md5`
+check — R10-7's first run tripped the harness's own line-indexed restore
+(a multi-line replacement), the harness reported `MISMATCH`, the file was
+restored from `git` and the harness was fixed to keep the whole original
+text. That is reported rather than quietly re-run.
+
+---
+
+## 7. What was NOT done, and what is not proven
+
+**Round 9's § 6 declared nine limits and the reviewer found a tenth that was
+in none of them.** That is the charge this round is answering, so this list is
+re-stated from scratch rather than amended, and the two entries the review
+created are first.
+
+1. **The static net does not see a row a CROSS-MODULE call produced.** § 4.
+   `perry_store.intake_table(board, ops)["header"]` is a row and
+   `offenders_by_symbol` cannot tell; the same is true of any row reaching a
+   reader through another module's dict, attribute or return. This is the hole
+   the round 9 reviewer's end-to-end plant actually walked through — the alias
+   was only half of it — and it is **not closed statically**, because closing
+   it is interprocedural source recognition and the amendment rejects that by
+   name. What covers it is the runtime watch, and only for readers a parse
+   reaches: `bin/perry-tasks` is now one of them, and the plant reddens
+   `test_every_fold_of_a_header_cell_came_from_header_index`. A converted
+   reader that is **not** driven and takes its row from another module is
+   covered by neither half. Every converted reader is now driven, so the set is
+   empty today; it is one unwatched conversion away from not being.
+2. **Three alias shapes are resolved and three are not**: a rebinding through a
+   container (`FOLDS["k"] = squash`), a function that RETURNS the rule
+   (`def picker(): return squash`), and a binding made in another module. The
+   first two are the second-rule class by another road; the third is (1).
+3. **The static net cannot see a second RULE — 0 of 41, measured.** Unchanged,
+   and ruled ACCEPTABLE by the round 9 review under option C. § 5.
+4. **The runtime watch only sees code a parse reaches.** A fold in a branch
+   these fixtures do not take, or for a ninth column beyond the eight in
+   `HEADER_KEYS`, is still invisible. `WATCHED` is now 16 readers and every one
+   is asserted.
+5. **`Watch` now reaches a CLI command function.** `cmd_intake_write` writes a
+   store to a throwaway root. Round 9's result could say "none reaches a CLI, so
+   `tests/gate.py`'s `GATE_OFF` is not involved"; that sentence no longer holds.
+   The driver builds its own `.perry/config.md` without `GATE_OFF` and asserts
+   `rc == 0`, so a gate refusal would fail the test rather than pass silently.
+6. **Round 5's probe cases `B` and `I` are unrecoverable** and are counted, not
+   invented.
+7. **`viewer/parsers.py:2582` (`parse_decisions`) is untouched** — a live
+   instance of the scalar second-rule class, established as dead code by rounds
+   3, 4 and 8. Not in scope; recorded so round 11 does not rediscover it.
+8. **`bin/perry-state § cells_of` was not removed** and `viewer/` was not
+   renamed. Separate rows, per the spec's closing note.
+9. **The three pre-existing failures were not investigated**, only measured as
+   identical on both trees under both runners.
+10. **No reader was driven end-to-end from `argv`.** Round 8's reviewer's
+    four-CLI byte-identical differential is **carried, not re-measured**.
+    `cmd_intake_write` is driven as a function, not through `main()`.
+11. **This branch is not rebased on `main`** (§ 6). 3 modules and 137 tests
+    exist on `main` that this branch has never run together with its own
+    changes.
+12. **`squash`'s docstring still says "do not map this across a header row"**,
+    which is half the rule. A one-line docs edit, not made, so this round's diff
+    stays what it says it is.
+13. **`test_the_row_splitter_half_is_owned_by_criterion_3` still asserts half
+    its docstring** — round 9's review, minor. It checks `SPLIT_RE` and not the
+    scan's coverage of `bin/` and `viewer/`. The reviewer verified that half by
+    planting; it is recorded, not fixed, because the lean is on another module's
+    test and widening this one duplicates it.
+
+---
+
+## 8. The three minor findings, closed
+
+1. **`D20` could not discriminate the hole it names.** `_plant` prepended
+   `SHEBANG` unconditionally, so `D20 "no suffix and NO SHEBANG"` and `S12`,
+   same subject, were planted **with** one. **Fixed on the plant side**, not on
+   the entry: `NO_SHEBANG` is two paths — keyed on the path the corpus already
+   guarantees unique via `test_no_two_entries_are_planted_at_the_same_path` — and
+   `test_the_no_shebang_entries_are_planted_without_one` asserts the bytes on
+   disk, that every exempted path is a real entry, and that the set and the
+   labels agree in both directions. Regression check, per the reviewer's own
+   proof: R10-7 (round 8's `is_python`) now reddens **`D20` and `D21`**, where
+   R9-6 reddened `D21` alone.
+2. **The `Watch` rebinding loop survived its own deletion.** **Kept and given a
+   test.** What it protects is real and is what this row forbids — a reader
+   holding its own reference to the rule and calling it directly — and nothing
+   does that today, which is why the loop was silent. So it is exercised
+   deliberately: `bin/perry-lint` holds `norm = squash`, and
+   `test_the_rebinding_loop_watches_a_readers_own_reference` asserts the loop
+   redirects it, that a fold through it reaches the watch, and that `__exit__`
+   puts it back. R10-9 (`for attr in ():`) reddens it.
+3. **`grep ROW_NAMES` returns two lines, not four.** § 4.3. Corrected here and
+   in round 9's result.

+# TASK-050 — V4 review round 10: **FAIL**
+
+> Fresh-context reviewer, 2026-08-30, against
+> `perry/evidence/2026-08/TASK-050-spec.md § Amendment 2026-08-29 — USER-904,
+> option C`, which binds.
+> Under review: `4c2f07a`, the read-only worktree at `scratchpad/review-050r10`
+> — round 10's code plus `main` merged in by the PMO after the author's numbers
+> were recorded. **Every plant, mutation and suite run below happened on
+> `git archive` exports and `cp -R` copies under `scratchpad/rjv4r10/`**, never
+> on the reviewed tree. No write-side Perry tool was run. No identifier was
+> minted. The reviewed worktree was verified byte-identical to its commit at
+> the start and at the end.
+
+**Round 9's charge is genuinely closed, and the author's counter-claim is
+TRUE.** I reproduced it myself: the reviewer's `bin/perry-tasks` plant crosses
+two independent holes, and the bare-`squash` variant with no alias at all
+escapes round 9's tree identically. The alias half is now shut — all ten of
+round 9's probe shapes are caught and both criterion-4 controls stay silent —
+and the cross-module half is covered by driving the reader. Every mutation I
+spot-checked reproduces, several pinning exactly one corpus entry.
+
+**It fails because the answer the round gives to the half it did not close
+statically is measured wrong, and I can falsify the amendment's own sentence on
+a live production file with the plainest possible spelling — no alias, no
+exotic shape.** A header row carried through a **dict key** is invisible to
+`offenders_by_symbol`, *including when the dict is built two lines above in the
+same function*; and `["header"]` is this repository's dominant idiom for
+holding a header row — **17 live sites, 12 of them in functions the runtime
+watch never reaches.** § 7 limit 1 says *"every converted reader is now driven,
+so the uncovered set is empty today."* It is not empty. It is twelve.
+
+---
+
+## THE RULING THIS REVIEW EXISTS FOR
+
+### 1. The author is right that the reviewer's plant crossed two holes. Measured.
+
+`scratchpad/rjv4r10/rjv4r10_crossmod.py`, one plant at a time into full copies,
+replaying the round 9 review's own two-site plant in three spellings:
+
+```
+tree-r9   alias        -> []     # `_fold = squash`, the reviewer's own plant
+tree-r9   bare         -> []     # SAME plant, bare `squash`, NO alias
+tree-r9   bare_direct  -> []     # folded straight off the cross-module call
+tree-r10  alias        -> []
+tree-r10  bare         -> []
+tree-r10  bare_direct  -> []
+```
+
+The bare variant escapes round 9's tree identically. **The alias was never the
+whole story**, and round 9's prescribed fix could not have closed that
+demonstration. That framing is vindicated, not a rationalisation.
+
+### 2. Closing a static hole with a runtime watch CAN satisfy the amendment — the mechanism is legitimate. This round's execution of it is not.
+
+I rule **for** the mechanism and **against** the claim made for it.
+
+The amendment asks for a *smaller surface*, and its verification section is
+about behaviour: *"reverting it now reddens a test."* Nothing in it says the
+one-symbol check must be static. Round 9's accepted ruling already rests on
+exactly this: `SECOND_RULE` is `0 of 41` and is acceptable **because the class
+is covered dynamically** — `test_every_decorated_header_cell_reached_header_index`
+goes red when a reader grows its own rule. A reviewer who accepts a dynamic
+cover for the second-rule class and rejects one for the cross-module row is
+applying two standards.
+
+And the cover is real. R10-10 reproduces on my copies: the reviewer's plant, in
+all three spellings, turns `test_every_fold_of_a_header_cell_came_from_header_index`
+**RED** on the round 10 tree, while the same plants are **OK** on round 9's:
+
+```
+tree-r10 alias / bare / bare_direct : FAIL test_every_fold_of_a_header_cell_came_from_header_index (Ran 8, FAILED 1)
+tree-r9  alias / bare               : Ran 7 tests  OK
+```
+
+**But a dynamic cover is only as good as its reach, and the reach is asserted
+in this round as a fact rather than measured.** That is where it fails. A
+runtime watch that covers 5 of 17 live instances of the exact shape it is
+offered for is not a cover; it is a sample. The rule I apply, and the one the
+next round should be held to: *a dynamic cover discharges a static hole only if
+the round measures which sites it reaches and states the remainder.* This round
+states the remainder as empty and it is twelve.
+
+---
+
+## Finding — the FAIL. A header row carried through a dict key is invisible to BOTH halves, and it is the repository's own idiom
+
+### The escape, on a copy of the reviewed tree
+
+`bin/perry_store.py § risk_plan` already reads its header out of a dict key
+(`header, keys = table["header"], table["keys"]`, line 854). One inserted line,
+bare `squash`, no alias:
+
+```python
+# scratchpad/rjv4r10/uncovered-store/bin/perry_store.py:854-855
+     header, keys = table["header"], table["keys"]
++    keys = [squash(c) for c in header]
+```
+
+```
+$ python3 -c "import sys;sys.path.insert(0,'tests');
+              from header_rule import offenders_by_symbol;print(offenders_by_symbol('.'))"
+[]
+$ python3 -m unittest discover -s tests -p 'test_header_index_is_the_only_fold.py'
+Ran 8 tests in 1.514s   OK
+$ python3 -m unittest discover -s tests -p 'test_one_header_rule.py'
+Ran 13 tests in 2.732s  OK
+$ python3 -m unittest discover -s tests -p 'test_row_integrity.py'
+Ran 33 tests in 0.859s  OK
+$ bash tests/run
+102 modules · 3034 tests · 331.8s · 8 workers
+✗ 2 module(s) red
+```
+
+The whole suite on that planted copy is **byte-for-byte the failure set of the
+unplanted tree** — the same two red modules and the same three names. Nothing
+in this repository notices.
+
+That is *"a call to `squash` on a row cell outside `header_index()`"* — the
+amendment's sentence, verbatim — on a converted reader, in a file the round
+counts as driven, with every guard this row ships reporting nothing.
+
+### It is NOT the cross-module hole the round declares, and the round's own reason for not closing it does not apply
+
+§ 7 limit 1 attributes the gap to another module and to a file-local walk being
+unable to see across one: *"closing that statically would be interprocedural
+row-source recognition across module and dict boundaries — the widening the
+amendment rejects by name."* Measured, that attribution is wrong. The shape
+escapes with **no module boundary at all** — with the dict literal built two
+lines above, inside the same function (`scratchpad/rjv4r10/rjv4r10_dict.py`,
+planted one at a time into copies, control included):
+
+```
+tree-r10  P1_local_dict_var    ESCAPED   t = table_of(line); hdr = t['header']; [squash(c) for c in hdr]
+tree-r10  P2_inline_dict       ESCAPED   t = {'header': split_row(line)}; [squash(c) for c in t['header']]
+tree-r10  P3_list_of_dicts     ESCAPED   [squash(c) for c in tables_of(line)[0]['header']]
+tree-r10  P5_attr_object       ESCAPED   t = T(line); [squash(c) for c in t.header]
+tree-r10  P4_control_direct    CAUGHT    [squash(c) for c in split_row(line)]
+```
+
+and with the repository's other spelling of the rule, `ops.norm`:
+
+```
+tree-r10  Q1_opsnorm_dict      ESCAPED   t = {'header': split_row(line)}; [ops.norm(c) for c in t['header']]
+tree-r10  Q2_opsnorm_direct    CAUGHT    [ops.norm(c) for c in split_row(line)]
+```
+
+`P2` is **local dataflow in one function**. `_RowLocals` already follows
+assignment, subscript, slicing, walrus, iterable wrappers, one comprehension
+unwrap, a parameter this file passes a row to, and *what a file-local function
+returns* — including `_, ihdr = ctx["board"].section_table("Intake")`, which I
+confirmed is caught (planted at `bin/perry-task:6456`, reported as
+`bin/perry-task:6456: [squash(c) for c in ihdr]`). Adding "a subscript of a
+dict this file built, or of what a file-local function returned" is one more
+`source()` case in machinery that already does the harder ones. **It is not
+option A.** Option A is widening recognition of the *fold expression*; this is
+the *row source*, and round 9's design deliberately expanded exactly that side.
+
+So the round's own justification — that the only alternative is the rejected
+widening — is not available for the shape that actually escapes.
+
+### § 4.2's first row and § 7 limit 1 are both falsified
+
+§ 4.2 claims `offenders_by_symbol` sees *"the rule applied to a row a **local**
+dataflow reaches, under any alias."* `P2` is a local dataflow and it is not
+seen.
+
+§ 7 limit 1 claims *"every converted reader is now driven, so the uncovered set
+is empty today; it is one unwatched conversion away from not being."* Measured
+on the reviewed tree:
+
+- **17 live sites** read a header row out of a dict key
+  (`table["header"]`, `tables[0]["header"]`, `tbl["header"]`, `site["header"]`)
+  across `bin/perry-task`, `bin/perry-tasks`, `bin/perry_store.py` and
+  `bin/perry_md_store.py`.
+- Driving the watch's own workload and collecting every function on a recorded
+  stack, **12 of the 17 sit in functions the watch never reaches at all**:
+  `_cmd_list_from_board`, `_task_sections`, `ask_plan`, `ask_section_shape`,
+  `ensure_columns`, `ensure_section_columns`, `find`, `plan`,
+  `refuse_foreign_risk_table`, `risk_plan`, `risk_section_shape`,
+  `task_tables`.
+- `WATCHED` is 16 functions; **59 `header_index`/`header_keys` call sites sit
+  in 45 enclosing functions, 34 of which are not in `WATCHED`.**
+
+The uncovered set is not empty today, and the limit is not one conversion away
+from growing — it already covers most of the places this repository holds a
+header row.
+
+### And the corpus does not plant it — the same structure as round 9's charge
+
+I enumerated every `DRIFT`, `CLEAN` and `SECOND_RULE` body. **No `DRIFT` entry
+carries a row through a dict or an attribute.** The corpus plants the alias
+passed to `map` and the alias used as a `sorted` key — two indirections a
+reader would have to reach for — and does not plant the one that is written
+seventeen times in the tree under review. That is the sentence round 9 wrote
+about `fold = squash`, with a different noun.
+
+### Why this fails the round rather than being recorded
+
+The three tests that were supposed to make the limits trustworthy are the
+reason. This round's whole answer to "the static half is blind here" is "the
+dynamic half is not", and § 7 re-states the limits *from scratch* precisely
+because round 9's list was found incomplete. The re-stated list gets the
+mechanism of the residual hole wrong (module boundary, when a dict literal in
+one function suffices), gets its size wrong (empty, when it is twelve), and
+justifies leaving it open by an exclusion — option A — that does not cover the
+shape. A declared limit that misdescribes what it declares is not a declared
+limit; it is the gap in a shape the next reviewer cannot check against.
+
+**It is also small to fix, and in the same idiom the design already uses:**
+teach `source()` that a subscript of a dict literal whose value is a row, or of
+what a file-local function returned, is a row (`_RowLocals.returns` already
+carries tuple positions; a string key is the same bookkeeping) — then plant the
+dict-carried and attribute-carried rows in `DRIFT` with their provenance, and
+either drive the twelve functions or state them by name.
+
+---
+
+## What holds, measured independently
+
+**The tree matches its commit.** Every tracked blob re-hashed against
+`git ls-tree -r HEAD`: **721 files, 0 mismatches**; `git status --porcelain`
+empty; `git ls-files -o --exclude-standard` empty. The hand restore the round
+volunteered (R10-7's line-indexed `MISMATCH`) left no residue. The round 10
+code diff is exactly three files under `tests/` — `git diff --stat b5e7be3
+a1ff426` is 366 insertions / 13 deletions — and the PMO's merge did not touch
+any of them (`git diff a1ff426 HEAD -- tests/header_rule.py
+tests/test_header_rule_harness.py tests/test_header_index_is_the_only_fold.py
+tests/test_one_header_rule.py` is empty).
+
+**The alias fix is real, and it is over the binding rather than the name.**
+`scratchpad/rjv4r10/rjv4r10_alias.py`, one plant at a time into copies, every
+drift body `[fold(c) for c in split_row(line)]`, controls included:
+
+| shape | round 9 | round 10 |
+|---|---|---|
+| `fold = lambda s: squash(s)` | CAUGHT | CAUGHT |
+| `def fold(s): return squash(s)` | CAUGHT | CAUGHT |
+| `fold = squash` | ESCAPED | **CAUGHT** |
+| `fold = squash`, scalar on a cell | ESCAPED | **CAUGHT** |
+| `from tables import squash as fold` | ESCAPED | **CAUGHT** |
+| `import tables; fold = tables.squash` | ESCAPED | **CAUGHT** |
+| `keyof = squash` (the repo's idiom, renamed) | ESCAPED | **CAUGHT** |
+| `a = squash; fold = a` (transitive) | ESCAPED | **CAUGHT** |
+| alias bound inside the reader | ESCAPED | **CAUGHT** |
+| alias bound OUT OF ORDER (`if:` then use) | ESCAPED | **CAUGHT** |
+| `map(fold, row)` / `sorted(row, key=fold)` | ESCAPED | **CAUGHT** |
+| CONTROL plain `squash` | CAUGHT | CAUGHT |
+| `tidy = str.strip` used on a row (criterion 4) | silent | **silent** |
+| alias used as a VALUE normalizer (criterion 4) | silent | **silent** |
+
+Round 9's FAIL is closed, and closed as a property of the *binding*: the two
+non-rule controls stay silent, so this is not a widened list of names.
+
+**Nine mutations reproduced on `cp -R` copies, each anchored by line and
+asserted against the exact old text before replacing. All seven anchors in
+`tests/header_rule.py` contain what the result says they contain.**
+
+| # | mutation | corpus entries reddened (mine) | claimed |
+|---|---|---|---|
+| R10-1 | `a.name in BLESSED` → `in ()` | **`D26` only** | D26 only ✓ |
+| R10-2 | `target = self._alias_target(…)` → `None` | `D25 D27 D28 D29 D30 D31` **+ `D32 D33`** (8) | 6 — **under-reported** |
+| R10-3 | `name = value.attr` → `return None` | **`D27` only** | D27 only ✓ |
+| R10-4 | fixpoint `range(4)` → `range(1)` | **`D30` only** | D30 only ✓ |
+| R10-5 | `rows.blessed` → `BLESSED` | **`D32` `D33`** | D32 D33 ✓ |
+| R10-6 | `rows.rule` → `THE_RULE` | **`D28` only** | D28 only ✓ |
+| R10-7 | `is_python` back to round 8's | **`D20` AND `D21`** | D20 and D21 ✓ |
+| R10-8 | `NO_SHEBANG` → `frozenset()` | `test_the_no_shebang_entries_are_planted_without_one` RED | ✓ |
+| R10-9 | `for attr in ("squash","norm")` → `for attr in ()` | `test_the_rebinding_loop_watches_a_readers_own_reference` RED | ✓ |
+
+Four single-entry mutations verified, which is the precision claimed. R10-2's
+under-report is in the safe direction (the guard is broader than advertised)
+and is consistent with the table having been written before `D32`/`D33` existed
+— recorded, not charged.
+
+**The two GREEN mutations are honestly reported and the re-plants are real.**
+`D30`'s body is `if os.name == "posix": a = squash` **then** `fold = a`, so
+`ast.walk`'s breadth-first order reaches the second link first and one pass
+cannot close it — my own out-of-order probe confirms this independently, and
+R10-4 (`range(1)`) reddens `D30` and only `D30`. **The fixpoint now earns its
+place.** `D32`/`D33` pass the alias without calling it, so the scalar half
+cannot see them, and R10-5 reddens exactly those two. Both re-plants do the
+work they are claimed to do.
+
+**R10-7 is the `D20` regression check and it holds.** Round 8's `is_python`
+reddens `D20` **and** `D21`, where R9-6 reddened `D21` alone. `_plant` writes
+`body if where in NO_SHEBANG else SHEBANG + body`, and
+`test_the_no_shebang_entries_are_planted_without_one` asserts the bytes on
+disk, that every exempted path is a real entry, and that the label set and the
+path set agree in **both** directions.
+
+**The `Watch` rebinding loop no longer survives its own deletion.** `for attr
+in ():` reddens `test_the_rebinding_loop_watches_a_readers_own_reference`
+(1 failure of 8). The test is not vacuous: it asserts `lint.norm is
+tables.squash` first, asserts the rebinding actually happened inside the
+context, folds a decorated cell **through the reader's own reference**, asserts
+the watch recorded it, and asserts `__exit__` restored it.
+
+**The corpus measures what the round says.** `measure()` on a `git archive`
+export: `{'drift_escaped': [], 'clean_flagged': [], 'second_rule_caught': []}`,
+`DRIFT 33 / CLEAN 12 / SECOND_RULE 41 / UNRECOVERABLE 2`. I read all nine new
+`DRIFT` bodies against the round 9 review's own escape list: `D25`←ESCAPED B,
+`D26`←ESCAPED E, `D27`←ESCAPED F, `D28`←ESCAPED C, `D29`←ESCAPED G,
+`D31`←the review's "a rebinding is not obliged to sit at module level",
+`D30`/`D32`/`D33`←this round's two green mutations. **None was invented to be
+easy**, and `D26`'s provenance note is exactly right that `D06` aliases onto
+`norm`, a name already in `BLESSED`.
+
+**`0 of 41` on `SECOND_RULE` is unchanged and I do not re-litigate it.** Round
+9's ruling stands.
+
+**The live tree is clean and the "exactly one alias" claim survives my own
+enumeration.** `offenders_by_symbol('.') == []` on the reviewed tree.
+Independently of the round's machinery I AST-swept every Python file in the
+repository — not only `readers_under` — for any binding of
+`squash`/`norm`/`header_index`/`header_keys` to another name by assignment,
+`import … as`, container literal or `return`. Outside `tests/` there is exactly
+one: **`bin/perry-lint:250 norm = squash`**, already blessed. (The three hits
+inside `tests/` are the `Watch` machinery; two apparent "container" hits in
+`bin/perry-goals` and `bin/perry_md_store.py` are `out = [squash(canonical)]`,
+a call, not the function object.)
+
+**R10-11 reproduces, both halves, and the contrast is the proof.** Planted into
+copies, `keyof = squash` at `bin/perry-lint:250` plus `value = keyof(key)` at
+`:348`:
+
+```
+tree-r10                offenders -> ['bin/perry-lint:349: keyof(key)']
+tree-r10 + round 9's header_rule.py   offenders -> []      <-- ESCAPED
+tree-r9                 offenders -> []                    <-- ESCAPED
+```
+
+and on the round 10 tree the plant reddens three named tests:
+`test_nothing_outside_header_index_maps_squash_across_a_row`,
+`test_value_normalizers_are_not_flagged` (13 tests, 2 failures) and
+`test_the_static_net_is_the_one_that_sees_dead_code` (8 tests, 1 failure).
+
+**Baselines — I name the tree for each.** All on `git archive` exports under
+`scratchpad/rjv4r10/`.
+
+| runner | tree | modules | tests | failures |
+|---|---|---|---|---|
+| `bash tests/run` | **`4c2f07a`, the reviewed merged tree** | **102** | **3034** | **3** |
+| `python3 -m unittest discover -s tests -p test_header_index_is_the_only_fold.py` | `4c2f07a` | — | **8** | 0 |
+
+This matches the PMO's measurement exactly and it is a **different tree from
+the author's 99 / 2897 / 3**, which its result documents and which I did not
+treat as a discrepancy. The three failures are the three this row has carried:
+`test_diagnose.DecisionsAreCountedPerRecordNotPerMention.test_the_queue_register_reconciles_with_the_queue_on_this_repository`,
+`test_diagnose.TestUserLoadFindings.test_perry_itself_passes_its_own_id_checks`,
+`test_kr_progress_provenance.TestBothOfTodaysWrongReadingsFlip.test_no_current_in_the_payload_claims_to_be_a_measurement`.
+Note that § 7 limit 11 — *"this branch is not rebased on `main`"* — is no longer
+true of the tree I reviewed; that is the PMO's merge, post-dating the document,
+not an author error.
+
+**§ 7's 13 limits genuinely re-derive round 9's nine plus what the review
+found, rather than renumbering.** Mapped one by one: R9-1→R10-3, R9-2→R10-4
+(and R10-1 for the newly-found half), R9-3→R10-6, R9-4→R10-7, R9-5→R10-8,
+R9-6→R10-9, R9-7→R10-10, R9-9→R10-12. R9-8 (the harness's `DIRTY` line) is
+dropped, correctly, because the harness was fixed. Five are new: R10-1
+(cross-module row), R10-2 (three unresolved alias shapes), R10-5 (`Watch` now
+reaches a CLI, so round 9's `GATE_OFF` sentence no longer holds — an honest
+retraction of the author's own prior claim), R10-11 (unrebased) and R10-13
+(`test_the_row_splitter_half_is_owned_by_criterion_3` still asserts half its
+docstring). The re-derivation is real work. It is the *content* of limit 1 that
+this review fails, not its bookkeeping.
+
+**`grep -rn "ROW_NAMES" tests/ bin/ viewer/` returns two lines**, both prose,
+no code. The correction is right.
+
+**No new test is green for a wrong reason that I could find.** None of the
+three modules greps its own source (`__file__` appears only as `PERRY_HOME` and
+`sys.path` roots; the single `read_text()` is the `NO_SHEBANG` bytes assertion
+on a planted file). `drive_intake_write`'s fixture is not vacuous: the workload
+records **34 distinct functions folding a decorated header cell**, and
+`cmd_intake_write` is among them. The `assertEqual(rc, 0)` and the
+`intake.jsonl` assertion are genuinely redundant — neutralising either leaves
+all 8 tests green — but the property they claim ("a refusal cannot pass as
+coverage") is still enforced, by
+`test_every_reader_this_module_claims_to_watch_actually_folds_one`, which I
+confirmed goes RED when `self.drive_intake_write()` is deleted.
+
+**Guards checked for surviving their own deletion, beyond the mutated set.**
+
+| deletion | result |
+|---|---|
+| `for attr in ("squash","norm")` → `for attr in ()` | **RED** (`test_the_rebinding_loop…`) — round 9's minor closed |
+| `self.drive_intake_write()` → `pass` | **RED** (`test_every_reader_this_module_claims_to_watch_actually_folds_one`) |
+| `"cmd_intake_write"` removed from `WATCHED` | **ALL GREEN** — see below |
+| `assertEqual(rc, 0, …)` neutralised | ALL GREEN (redundant, property held elsewhere) |
+| `assertTrue((root/"intake.jsonl").exists())` neutralised | ALL GREEN (same) |
+
+The third row is the answer to the brief's question about limit 1's growth.
+`WATCHED` is asserted in one direction only — every listed reader must fold —
+and there is **no converse check**: nothing fails when a converted reader is
+absent from the list. I verified by deletion. Combined with the finding above,
+this is not merely "no guard against growing": the list is already short of the
+readers that matter.
+

+
+## Smaller results, reported because they are results
+
+- **R10-2 reddens eight corpus entries, not the six § 3.1 lists** (`D32` and
+  `D33` are also alias-resolution dependents). Safe direction; the table
+  appears to predate those entries.
+- **A row carried on an object attribute escapes too** (`t = T(line);
+  [squash(c) for c in t.header]`, `P5`), on both trees. Same family as the
+  dict; recorded so the fix covers both.
+- **`_, ihdr = ctx["board"].section_table("Intake")` IS resolved.** I planted
+  `[squash(c) for c in ihdr]` at `bin/perry-task:6456`, inside
+  `_cmd_list_from_board`, a function the watch never reaches, and the static
+  net caught it. The tuple-unpack-of-a-returned-row machinery is strong; it is
+  specifically the dict/attribute step that is missing.
+- **`WATCHED` cannot distinguish two readers with the same function name.**
+  `header_language` exists in both `bin/perry-goals` and `bin/perry-task`, and
+  the watch records bare function names, so one entry can be satisfied by
+  either. Not load-bearing today; recorded.
+- **`viewer/parsers.py § parse_decisions`** is still a live instance of the
+  scalar second-rule class and still dead code. Agreed out of scope, per § 7.7.

+task: TASK-050
+rung: V4
+result: FAIL
+criteria: perry/evidence/2026-08/TASK-050-spec.md § Amendment 2026-08-29 — USER-904,

+checked: Worktree verified byte-identical to 4c2f07a (721 tracked blobs
+         re-hashed, 0 mismatches; porcelain and ls-files -o both empty) at
+         start and end. Round 10 code diff confirmed to be three files under
+         tests/ (366+/13-) and untouched by the PMO's merge.
+         bash tests/run on a git archive export of the REVIEWED MERGED TREE
+         4c2f07a: 102 modules / 3034 tests / 3 failures, the three names this
+         row has carried; test_header_index_is_the_only_fold 8 tests OK. The
+         author's 99/2897/3 is a different tree and was not treated as a
+         discrepancy.
+         Round 9's ten alias shapes replanted one at a time into copies of BOTH
+         trees: all escapes reproduce on round 9 and all are CAUGHT on round
+         10, with both criterion-4 controls silent, so the guard is over the
+         binding and not the name.
+         Nine mutations reproduced on cp -R copies, each anchored by line and
+         asserted on the exact old text: R10-1 -> D26 only, R10-3 -> D27 only,
+         R10-4 -> D30 only, R10-6 -> D28 only (four single-entry mutations
+         verified), R10-5 -> D32+D33, R10-7 -> D20 AND D21 (the D20 regression
+         check holds), R10-8 and R10-9 red. R10-2 reddens EIGHT entries, not
+         the six claimed — safe direction, recorded.
+         D30's out-of-order re-plant confirmed genuine and the fixpoint now
+         earns its place. R10-11 reproduced both halves: keyof=squash at
+         perry-lint:250 reports 'bin/perry-lint:349: keyof(key)' and reddens
+         three named tests, while the identical plant against round 9's
+         header_rule.py returns []. R10-10 reproduced: the reviewer's plant
+         reddens test_every_fold_of_a_header_cell_came_from_header_index on
+         round 10 and is OK on round 9.
+         Corpus measured 33/12/41+2 with nothing escaping or falsely flagged;
+         all nine new DRIFT bodies read and traced to the round 9 review or to
+         this round's green mutations — none invented to be easy.
+         "Exactly one alias" verified by my own repo-wide AST sweep, not the
+         round's machinery: bin/perry-lint:250 norm = squash, and nothing else
+         outside tests/. offenders_by_symbol('.') == [] on the reviewed tree.
+         Guard-deletion survival checked beyond the mutated set (five
+         deletions, table above). § 7's 13 limits mapped one-by-one onto round
+         9's nine; the re-derivation is real, not a renumbering.
+         Worktree re-verified byte-identical at the END of the review (721
+         blobs, 0 mismatches, porcelain and ls-files -o empty).
+         Every plant, mutation and suite run on git-archive exports and cp -R
+         copies under scratchpad/rjv4r10; no write-side Perry tool; no
+         identifier minted.
+not-checked: did not drive any reader end-to-end from argv — round 8's
+         four-CLI byte-identical differential is carried, not re-measured; did
+         not re-run bash tests/run on round 9's tree or on the author's own
+         99/2897 export; did not investigate the three pre-existing failures
+         beyond confirming their names; did not re-derive round 9's ruling that
+         0 of 41 on SECOND_RULE is acceptable, which I carry; did not audit the
+         write side, localized headers, or non-Python readers; did not verify
+         R9-6's original D21-only attribution myself (carried from the round 9
+         review, and R10-7's two-entry result is consistent with it).
+proof: The amendment's sentence — "no call to `squash` on a row cell exists
+       outside `header_index()`" — is falsified on a live production file with
+       the plainest possible spelling: no alias, no wrapper, no exotic shape.
+       A header row carried through a DICT KEY is invisible to
+       offenders_by_symbol, and `["header"]` is this repository's own idiom
+       for holding one.
+       On a full copy at scratchpad/rjv4r10/uncovered-store, one line inserted
+       into bin/perry_store.py § risk_plan, which already reads
+       `header, keys = table["header"], table["keys"]` at :854:
+           +    keys = [squash(c) for c in header]
+         offenders_by_symbol('.')                            -> []
+         test_header_index_is_the_only_fold.py   Ran 8 tests   OK
+         test_one_header_rule.py                 Ran 13 tests  OK
+         test_row_integrity.py                   Ran 33 tests  OK
+       and bash tests/run on that same planted copy: 102 modules / 3034 tests /
+       the SAME two red modules and three failure names as the unplanted tree
+       (331.8s, 8 workers). Nothing in this repository notices.
+       The round's stated reason for leaving this open does not apply to it.
+       § 7 limit 1 calls it "interprocedural row-source recognition across
+       module and dict boundaries — the widening the amendment rejects by
+       name". It is not interprocedural: the shape escapes with NO module
+       boundary at all (scratchpad/rjv4r10/rjv4r10_dict.py, copies, one plant
+       at a time, control included):
+         ESCAPED  t = {'header': split_row(line)}; [squash(c) for c in t['header']]
+         ESCAPED  t = table_of(line); hdr = t['header']; [squash(c) for c in hdr]
+         ESCAPED  [squash(c) for c in tables_of(line)[0]['header']]
+         ESCAPED  t = T(line); [squash(c) for c in t.header]
+         ESCAPED  t = {'header': split_row(line)}; [ops.norm(c) for c in t['header']]
+         CAUGHT   CONTROL [squash(c) for c in split_row(line)]
+       The first is local dataflow inside one function. _RowLocals already
+       follows assignment, subscript, slicing, walrus, wrappers, a comprehension
+       unwrap, a parameter this file passes a row to, and what a file-local
+       function RETURNS — I confirmed it catches
+       `_, ihdr = ctx["board"].section_table("Intake")` planted at
+       bin/perry-task:6456. A dict subscript is one more source() case in that
+       same machinery, not recognition of a fold expression, so option A is not
+       the alternative here.
+       And the dynamic half does not cover it. § 7 limit 1 asserts "every
+       converted reader is now driven, so the uncovered set is empty today."
+       Measured on the reviewed tree: SEVENTEEN live sites read a header row
+       out of a dict key across bin/perry-task, bin/perry-tasks,
+       bin/perry_store.py and bin/perry_md_store.py; driving the watch's own
+       workload and collecting every function on a recorded stack, TWELVE of
+       them sit in functions the watch never reaches at all — _cmd_list_from_board,
+       _task_sections, ask_plan, ask_section_shape, ensure_columns,
+       ensure_section_columns, find, plan, refuse_foreign_risk_table, risk_plan,
+       risk_section_shape, task_tables. WATCHED is 16 functions against 45
+       enclosing functions holding the 59 header_index/header_keys call sites,
+       and it is asserted in ONE direction only: removing "cmd_intake_write"
+       from WATCHED leaves all 8 tests green, so nothing fails when a reader is
+       absent from the list.
+       The corpus does not plant this shape. No DRIFT entry carries a row
+       through a dict or an attribute, while D32 and D33 plant an alias passed
+       to map and to sorted(key=) — the same structure as round 9's charge that
+       "the corpus plants both HARDER indirections and neither easy one", with
+       a different noun.
+       RULING ON THE QUESTION THE ROUND TURNS ON: closing a static hole with a
+       runtime watch DOES satisfy the amendment in principle, and I rule for
+       the mechanism. The amendment nowhere requires the one-symbol check to be
+       static, its own verification section is stated as "reverting it reddens a
+       NAMED test", and round 9's accepted ruling on 0 of 41 already rests on a
+       dynamic cover for the second-rule class — a reviewer cannot accept that
+       and reject this. The cover is real and I measured it: the round 9
+       reviewer's plant, in all three spellings, reddens
+       test_every_fold_of_a_header_cell_came_from_header_index on round 10 and
+       is OK on round 9. But a dynamic cover discharges a static hole only if
+       the round MEASURES which sites it reaches and states the remainder. This
+       round states the remainder as empty and the remainder is twelve. That is
+       what fails.
+       ALSO RULED, FOR THE AUTHOR: the claim that the reviewer's bin/perry-tasks
+       plant crosses two independent holes is TRUE, reproduced here — the same
+       plant written with a bare `squash` and no alias escapes round 9's tree
+       identically ([] on tree-r9 for alias, bare, and bare-direct spellings).
+       Round 9's prescribed fix could not have closed that demonstration, and
+       the framing is not a rationalisation. Round 9's actual charge — the guard
+       stated over the spelling — is fully closed: ten alias shapes caught, two
+       criterion-4 controls silent, four mutations each reddening exactly one
+       corpus entry. The three minor findings are closed with evidence, the two
+       green mutations were reported as findings and their re-plants do real
+       work, and the harness incident was recorded rather than re-run.
+       The fix is again small and in the design's own idiom: teach source()
+       that a subscript of a dict this file built — or of what a file-local
+       function returned — is a row; plant the dict-carried and
+       attribute-carried rows in DRIFT with their provenance; and either drive
+       the twelve named functions or state them by name instead of "empty".

+
+Round 10's review was a FAIL and largely a ruling in the round's favour. It
+ruled **for** the mechanism the round turns on — *"closing a static hole with a
+runtime watch DOES satisfy the amendment"* — verified round 9's charge fully
+closed across ten alias shapes with both criterion-4 controls silent,
+reproduced nine mutations including four that redden exactly one corpus entry,
+confirmed the fixpoint earns its place, confirmed the corpus was not pruned,
+and ruled that the round's counter-claim about the round 9 reviewer's plant was
+TRUE.
+
+It failed the round on one sentence — § 7 limit 1:
+
+> *"every converted reader is now driven, so the uncovered set is empty today"*
+
+and on the rule behind it:
+
+> *"A dynamic cover discharges a static hole only if the round MEASURES which
+> sites it reaches and STATES the remainder. This round states the remainder as
+> empty; it is twelve."*
+
+**Round 11 is that measurement, the local half of the hole closed statically,
+and a `WATCHED` list that no longer survives its own deletion.** No production
+code changed: `git diff --stat 4c2f07a..HEAD -- bin/ viewer/ schema/ templates/
+packs/ modes/` is empty. The code diff is the same three files under `tests/` —
+863 insertions, 15 deletions.
+
+---
+
+## 0. What changed, in one list
+
+1. **A row carried on a DICT KEY is a row.** `_RowLocals` gains one more
+   `source()` case, in the bookkeeping `returns` already used for tuple
+   positions. The reviewer's exact plant at `bin/perry_store.py:855` is now
+   reported and reddens three named tests (§ 1).
+2. **The round 10 sentence is corrected.** The escape is not interprocedural.
+   The local case is closed; a genuinely cross-module case remains, and it is
+   described as what it is and counted (§ 1.2, § 7).
+3. **The remainder is MEASURED, not asserted.** `header_rule.header_sites()`
+   enumerates 76 sites; `Reach` records what the workload enters;
+   `test_the_uncovered_remainder_is_the_measured_one` recomputes the
+   difference. It was 20 under round 10's tree and workload. **It is 8** (§ 2).
+4. **Nine of the twelve functions the reviewer named are DRIVEN**, not named
+   (§ 2.2).
+5. **`WATCHED` is asserted in both directions.** The reviewer's own deletion —
+   removing `cmd_intake_write` — now reddens a named test, and so does
+   converting a reader, driving it, and not listing it. `WATCHED` was short by
+   eight and one of the eight was already being driven (§ 3).
+6. **The corpus plants the shape.** Fourteen new `DRIFT` entries and five new
+   `CLEAN` controls: `DRIFT` 33 → 47, `CLEAN` 12 → 17 (§ 4).
+7. **Thirty-one mutations, all red, thirteen of them single-entry**, with every
+   anchor resolved from TEXT at run time rather than carried as a line number
+   (§ 5).
+8. **The machinery was swept for branches that survive their own deletion —
+   by hand (18 probes, 10 deleted), then MECHANICALLY from the diff (128
+   candidates, 20 green, none a detection branch), and then again past the
+   bound the second sweep declared (85 candidates), which is where criterion
+   4's failure mode was hiding** (§ 1.5).
+9. **R10-2's count is corrected to eight**, as the round 10 review said (§ 8),
+   and the round 11 review's three corrections are applied and re-measured
+   (§ 2.3, § 5, § 1.5).
+
+---
+
+## 1. The FAIL — a row carried on a dict key
+
+### 1.1 What escaped
+
+`bin/perry_store.py § risk_plan` reads its header out of a dict key at line
+854. One inserted line, bare `squash`, no alias, no wrapper:
+
+```
+     header, keys = table["header"], table["keys"]
++    keys = [squash(c) for c in header]
+```
+
+On round 10's tree `offenders_by_symbol` returned `[]`, all three header
+modules were green, and `bash tests/run` was byte-for-byte the failure set of
+the unplanted tree. `["header"]` is this repository's dominant idiom for
+holding a header row: **17 live sites** across `bin/perry-task`,
+`bin/perry-tasks`, `bin/perry_store.py` and `bin/perry_md_store.py`.
+
+### 1.2 It is NOT interprocedural — round 10's own reason did not apply
+
+Round 10's § 7 limit 1 attributed the gap to a module boundary:
+
+> *"closing that statically would be interprocedural row-source recognition
+> across module and dict boundaries — the widening the amendment rejects by
+> name."*
+
+The reviewer measured that this is wrong, and the measurement is reproduced
+here: the shape escapes with the dict literal built two lines above, **inside
+one function**. That is local dataflow, and `_RowLocals` already resolves
+strictly harder local shapes — a `def` wrapper, a name-bound `lambda`, a
+transitive alias chain bound out of order, a parameter this file passes a row
+to, and what a file-local function RETURNS, including
+`_, ihdr = ctx["board"].section_table("Intake")`.
+
+**The correct statement of the limit, which § 7 now carries, is that a header
+row whose producing chain crosses a MODULE boundary is not resolved — and that
+statement comes with a size.** Of the 17 carried sites, the six inside
+`bin/perry_store.py` itself now resolve; the other eleven are each rooted in a
+call into another module (`perry_store.markdown_tables`,
+`perry_store.intake_table`, `board.task_tables()`).
+
+### 1.3 The fix — one more `source()` case
+
+A **path** says where a row sits inside a value, read left to right:
+`("key:header",)` — subscript by that string; `("elem", "key:header")` — index
+or iterate first; `("pos:1", …)` — a tuple position first; `("attr:header",)` —
+an object attribute. The empty path is the row itself and stays in
+`self.scope`, so nothing is answered twice.
+
+**It is provenance, not recognition.** A path exists only because an expression
+in *this file* put a row there. `ROW_NAMES` stays deleted; no key name is
+consulted by `offenders_by_symbol`. The controls prove the difference: a dict
+whose value is a value (`{"status": rec.get("status")}`) folded by `squash` is
+silent, and so is the generator that yields one — `C13` and `C14`.
+
+The four links of `bin/perry_store.py` now resolve end to end: `markdown_tables`
+APPENDS `{"header": split_row(...)}` to `out`; `risk_section_shape` returns
+`("table", tables)`; `risk_table` INDEXES `tables[0]`; `risk_plan` UNPACKS
+`header, keys = table["header"], table["keys"]`.
+
+A second local case was open one function further on and is also closed:
+`bin/perry-task § _section_tables` is *"the ONE walk over the board's
+task-bearing sections"* and hands its tables over by `yield`, which fed nothing.
+
+### 1.4 The reviewer's exact plant, replayed on `9d00f1b`
+
+On a `git archive` export with the same line inserted at `perry_store.py:855`:
+
+```
+offenders_by_symbol('.')
+  -> ['bin/perry_store.py:855: [squash(c) for c in header]',
+      'bin/perry_store.py:855: squash(c)']

+    test_value_normalizers_are_not_flagged
+test_row_integrity                   Ran 33  OK   (not its criterion)
+```
+
+Three named tests, which is the amendment's own verification sentence.
+
+The shape list, one plant at a time into copies, controls included:
+
+| shape | round 10 | round 11 |
+|---|---|---|
+| `t = {"header": split_row(l)}; [squash(c) for c in t["header"]]` | ESCAPED | **CAUGHT** |
+| `t = table_of(l); hdr = t["header"]; [squash(c) for c in hdr]` | ESCAPED | **CAUGHT** |
+| `[squash(c) for c in tables_of(l)[0]["header"]]` | ESCAPED | **CAUGHT** |
+| `for tbl in tables_of(ls): [squash(c) for c in tbl["header"]]` | ESCAPED | **CAUGHT** |
+| `t = T(line); [squash(c) for c in t.header]` (attribute) | ESCAPED | **CAUGHT** |

+| `squash(t["header"][0]) == "id"` (the scalar half) | ESCAPED | **CAUGHT** |
+| the four-link append/tuple/index/unpack chain | ESCAPED | **CAUGHT** |

+### 1.5 Ten branches DELETED because nothing measured them
+
+**[review correction 3] The first draft of this section described a sweep of
+eighteen HAND-CHOSEN probes. The review found two branches it never reached —
+the `YieldFrom` step and `ast.Set` in the literal branch — and said the right
+thing about it: a claim that a sweep found everything is a completeness claim.
+So the sweep was rebuilt to take its candidates from `git diff` instead of from
+me.** What follows is the hand sweep (which did real work and is kept, because
+the ten deletions came out of it) and then the mechanical one that replaced it.
+
+### The hand sweep — eighteen probes, ten deleted
+
+Eighteen survival probes were run over the new machinery, each neutralised
+alone. **Ten came back green** — the whole corpus stayed caught **and** the
+live census stayed at 76 sites / 27 static-blind / no offenders — so they were
+speculation and are deleted rather than carried:
+
+`extend`/`update`, `insert` and `setdefault` container fills; an iterable
+wrapper, `.copy()`, `.get("k")` and a `BoolOp` inside `_paths`; the slice
+branch; the integer-subscript branch (the `elem` fallback already answers
+`tables[0]`); and a parameter carrying a table's paths.
+
+That is this row's own lesson applied to its own code: round 8 was failed for
+keeping a half nothing measured, and an unmeasured half is a liability whichever
+direction it errs in.
+
+An eleventh probe came back green and was a **corpus gap** rather than dead
+code — the loop-target binding, a LOOP over a list of tables rather than an
+index into one, which is how `bin/perry_md_store.py:468` and `:543` and
+`bin/perry_store.py:531` each read a header. `D42` plants it, and the probe
+(R11-12) now reddens `D42` and only `D42`. The remaining seven probes were red
+from the start and are R11-9, R11-10, R11-11, R11-13, R11-14, R11-16 and R11-17
+in § 5 — seven red, ten deleted, one corpus entry, eighteen in all.
+
+### The mechanical sweep — 128 candidates, taken from the diff
+
+The candidate list is every `if`/`elif` test, every conditional expression and
+every simple statement whose line `git diff -U0 4c2f07a..HEAD --
+tests/header_rule.py` reports as new or changed: **337 lines, 128 candidates.**
+Each mutant is built on the AST and written back with `ast.unparse`, so a
+multi-line condition or a continuation line cannot break the syntax the way a
+text-anchored edit can — and a **control run unparses the tree without mutating
+anything** and stays green, so the round trip itself is not doing the work.
+
+Each candidate is probed against the corpus, and every candidate that comes
+back clean there is probed again against the **runtime** half, so *green* means
+"the whole corpus is still caught AND
+`test_the_uncovered_remainder_is_the_measured_one` is unmoved".
+
+```
+candidates                                        128
+RED in the corpus                                  60
+RED in the watch                                   26
+UNNEUTRALISABLE (the module cannot run without it)  22
+GREEN                                              20
+```
+
+The first run of it found **four more unpinned DETECTION branches** on top of
+the review's two. Each is a single-entry mutation in § 5. **Three are the live
+shape; two are not, and the round 11 review was right to ask** — the column is
+headed accordingly rather than claiming a live instance for all five:
+
+| entry | branch it pins | shape, and whether this tree contains one |
+|---|---|---|
+| `D43` | the `YieldFrom` step | **no live instance.** `yield from` re-yields, so it must NOT add an element level; a step that gets it wrong reads one subscript too deep |
+| `D44` | `_rpaths_of` by ATTRIBUTE name | LIVE: `Board.task_tables()`, `bin/perry_store.py § plan` — minus the cross-module root |
+| `D45` | `_bind_element` on a COMPREHENSION generator | LIVE in family: the list of dicts of `bin/perry_md_store.py:468`, walked by a comprehension |
+| `D46` | the `cell()` half of the tuple unpack | LIVE: `bin/perry_store.py:857`, `i, cells = row["line"], row["cells"]` |
+| `D47` | the SUBSCRIPT half of the carried write | **no live instance.** `D24`'s sibling — a dict assignment built the header index, this one holds the header row |
+
+`ast.Set` was **deleted** rather than planted: a row is a list, a list is not
+hashable, so a row cannot be an element of a set literal — it survived its own
+deletion because it is unreachable.
+
+**Twenty green mutants remain, and none of them is a detection branch.** They
+are named here rather than counted, because "none is a detection branch" is a
+claim and this is what it rests on:
+
+| green | what it is | why a planting corpus cannot pin it |
+|---|---|---|
+| L418 L419 | `if self.of(node) is not f: continue` in the `yield` loop | an owner filter; only bites on a `yield` inside a nested function |
+| L499 L500 | `if not isinstance(t, ast.Name): continue` | a target-shape guard |
+| L506 L509 L512 L513 L514 | the `bound` flag and its `continue` | round 9's guard against the generic fall-through marking `_` a row |
+| L584 | `_bind_element`'s target guard | same |
+| L609 | `_rpaths_of`'s `isinstance(node, ast.Call)` guard | same |
+| L694 L695 L696 | `source()`'s default-scope normalisation and its `_source_direct` short-circuit | `_paths` calls `_source_direct` itself, and the scalar half catches these bodies independently — defence in depth, the same reason R11-1 does not redden `D38` |
+| L848 L852 L853 L856 | `header_sites`'s `Path(root)`, its two `warnings` filters and its `continue` on an unparseable file | plumbing copied from `offenders_by_symbol` |
+| L877 L878 | the census's ATTRIBUTE half | dead on this tree: all seventeen live carried sites are subscripts. A stated limit of the MEASUREMENT (§ 7.14) |
+
+Two of the twenty — L695 and L418 — were re-verified by hand with
+text-anchored mutations rather than AST ones, because a sweep that disagrees
+with a hand check is a broken sweep. Both agreed.
+
+**What that sweep did not claim** — stated in the first draft of this document,
+in writing: *it mutates whole `if` tests, not individual conjuncts of an `and`;
+it does not mutate constants, operators or f-string contents; and it covers
+`tests/header_rule.py` only.*
+
+### The delta sweep — a declared bound is not a covered class
+
+**[review correction, the delta pass] The round 11 review ran the sweep that
+bound excludes, and the bound was hiding criterion 4's failure mode.** 36 BoolOp
+operands, each replaced by its operator's identity constant. One red: dropping a
+single conjunct at `tests/header_rule.py:659`,
+
+```
+if p and p[0] == f"attr:{node.attr}"        ->        if p:
+```
+
+makes the net **report a legitimate value normalizer** — an object that carries
+a real header row on `.header` and ordinary values on `.statuses`, folded
+`[squash(s) for s in t.statuses]` — **while the entire 47-entry corpus stays
+silent**, `escaped []`, `flagged []`. That is the exact shape round 8 was failed
+for. Reproduced here before anything was changed. The verdict did not turn on
+it because the bound was declared and the shipped code is correct — but a bound
+declared is not a class covered, and the corpus now reaches inside it.
+
+So the sweep was extended to the two classes it excluded, candidates still from
+`git diff`:
+
+- **each operand of an `and`/`or`** replaced by its operator's identity
+  constant — "drop this conjunct" without touching the rest of the test;
+- **every `if` test set to `True`** as well as to `False`. The first sweep only
+  ever WEAKENED a test. A criterion 4 failure is a test that fires too OFTEN,
+  and only a strengthening mutation reaches one. **That is the structural
+  reason the class was invisible — not an oversight about one line**, which is
+  why the answer is a second sweep and not a second patch.
+
+```
+candidates                                         85   (36 operands + 49 if-tests)
+RED in the corpus                                  17
+RED in the watch                                   16

+GREEN                                              26
+```
+
+It found a **second live instance of the same class**, which is the evidence
+that the first was not a one-off: `tests/header_rule.py:654`, `elif p[0] ==
+"elem":` → `elif True:`. The `elem` fallback answers `tables[0]` and is guarded
+by the key not being a string; forced to fire anyway it reports `t[which]` — a
+table dict indexed by a computed key beside a real header row — and the same
+shape with a non-string constant key.
+
+Three `CLEAN` entries close both, and **no machinery changed**:
+
+| entry | shape | pinned by |
+|---|---|---|
+| `C15` | a DECOY ATTRIBUTE beside a real header row | R11-28, `C15` only |
+| `C16` | a DECOY KEY beside a real header row | R11-29, `C16` only |
+| `C17` | a table dict indexed by a VARIABLE key | R11-30, `C17` only |
+
+**26 greens remain, and this document does not claim they are harmless.** Four
+were probed for over-firing with constructed decoy shapes; one produced a false
+positive (`:654`, now `C17`) and three did not — `q[0] == "elem"` in
+`_bind_element`, the non-string dict key, and the `p` truthiness guard at `:659`.
+**The other 22 are unprobed.** They are guards and normalisation of the same
+kinds listed above, but "unexercised" is what this section is for and an
+unprobed green is not a proven-safe one.
+
+**What the delta sweep still does not claim**: it does not mutate constants,
+operators, comparison directions or f-string contents; it does not mutate
+`tests/test_header_index_is_the_only_fold.py`; and it probes over-firing against
+the corpus, so a false positive on a shape nobody planted is still invisible to
+it. That is the same class of bound as the one that hid `:659`, stated in the
+same place, and the next round should assume it hides something too.
+
+---
+
+## 2. The measured remainder — 8
+
+### 2.1 The instrument
+
+`tests/header_rule.py § header_sites(root)` enumerates every place a reader
+holds a header row, in two kinds:
+
+- **`convert`** — an argument of `header_index`/`header_keys`. Spelling-free:
+  derived from the blessed call itself. **59 sites in 51 functions.**
+- **`carried`** — a subscript or attribute read whose key is one of
+  `CARRIED_KEYS = ("header", "headers", "hdr")`. **17 sites in 17 functions.**
+
+Each carries a **static verdict**: does `_RowLocals` resolve that expression as
+a row — which is exactly whether a `squash` planted on it in the same function
+is reported by `offenders_by_symbol`.
+
+`tests/test_header_index_is_the_only_fold.py § Reach` records, with
+`sys.setprofile`, every function of this repository the watch's workload
+ENTERS. A site is covered when the static half resolves it **or** the dynamic
+half enters its function; the rest is the remainder.
+
+`test_the_uncovered_remainder_is_the_measured_one` recomputes that difference
+every run and asserts it equals `UNCOVERED`, **in both directions** — a
+remainder that grows fails, and a remainder stated larger than it is fails too.
+
+### 2.2 The numbers
+
+All on `9d00f1b`, `sites=76`, `static-blind=27` in every row (the static half
+does not move with the workload):
+
+| | remainder |
+|---|---|
+| round 10's workload | **20** |
+| round 11's workload | **8** |
+
+Cross-checked with a **line-level** trace of the same workload rather than a
+function-level one: the same 20 and the same 8, the same members
+(`agree: True`). The coarser question is not hiding anything today.
+
+Nine of the twelve functions the reviewer named are now DRIVEN rather than
+named — `task_tables`, `_task_sections`, `find`, `ensure_columns`,
+`ensure_section_columns`, `task_section_headings`, `replace_row`,
+`refuse_foreign_risk_table` (on its refusal path, asserted with
+`assertRaises`), plus `canonical_of` and `is_user_register_header`. The
+write-side three edit the lines they are handed, so they run against
+`WRITE_BOARD`, a fixture of their own.
+
+### 2.3 The eight, by name
+
+```
+carried  bin/perry-task        _cmd_list_from_board
+carried  bin/perry_md_store.py plan
+carried  bin/perry_store.py    plan
+convert  bin/perry-lint        check_cross_file
+convert  bin/perry-lint        check_reviews
+convert  bin/perry-lint        check_verification
+convert  bin/perry-task        task_projection_row
+convert  bin/perry_store.py    plan
+```
+
+**[review correction 1] They are open for TWO different reasons, and the first
+draft of this section gave one reason for all eight. It was wrong for three.**
+
+- **Five are rooted in a call into ANOTHER MODULE** — `_cmd_list_from_board`,
+  `task_projection_row`, `perry_md_store § plan` and `perry_store § plan`
+  (both its sites). Each reaches its row through `perry_store.markdown_tables`,
+  `perry_store.intake_table` or a `Board` defined elsewhere.
+  `tests/header_rule.py` is file-local by construction, so these need the
+  interprocedural step the amendment rejects.
+- **Three are NOT.** The `bin/perry-lint` sites reach their row through
+  `tables()`, which is defined at `bin/perry-lint:194`, on top of
+  `tables_with_lines()` at `:209` — **both in the same file**. What they
+  escape through is that **`_paths` has no comprehension branch**:
+  `tables()` is `[(h, [c for c, _ in r]) for h, r in tables_with_lines(...)]`,
+  and a path does not travel through a comprehension's element expression.
+
+  Reproduced here on a synthetic file with **no cross-module call anywhere**:
+  the `bin/perry-lint` shape ESCAPED, and the identical file with the
+  comprehension unrolled into an explicit loop was CAUGHT.
+
+**The consequence, said plainly: the honest target for the next round is 5,
+not 0.** Three of these eight are closable by the same file-local machinery
+this round already built — one more `_paths` case for a comprehension, with
+its own corpus entry and its own mutation — and the remaining five are the
+cross-module limit.
+
+This is the same species of error as round 10's, one rung smaller: *which*
+sites and *how many* were right, *why* was wrong for three of them.
+
+### 2.4 Reconciliation with the reviewer's twelve
+
+The review reported *"17 live sites … 12 of them in functions the watch never
+reaches"*. Measured here with a profiler rather than a capped stack, under
+round 10's workload: **13 carried sites in 12 distinct function names** — the
+reviewer's twelve names exactly, with `plan` standing for two files. The two
+counts agree; they count different things (names versus sites). Under round
+11's workload it is **7 sites in 6 names**.
+
+---
+
+## 3. `WATCHED` no longer survives its own deletion
+
+Round 10's review:
+
+> *"`WATCHED` is asserted in one direction only … removing `cmd_intake_write`
+> from `WATCHED` leaves all 8 tests green, so nothing fails when a reader is
+> absent from the list … the list is already short of the readers that
+> matter."*
+
+`test_watched_is_exactly_the_converted_readers_this_workload_folds_through`
+asserts SET EQUALITY, and **the other side of the equality is not written in
+this module**: it is `header_sites()`, walking the tree for every function that
+calls `header_index`/`header_keys`. Frames are matched by FILE as well as by
+name, so neither a unittest runner frame nor the `header_language` that exists
+in two readers can answer for another.
+
+Two failures follow from one assertion, and both are verified by mutation:
+
+- **R11-18**, the reviewer's own deletion of `"cmd_intake_write"` → RED.
+- **R11-19**, convert-and-forget: dropping `"is_intake_register_header"` → RED.
+
+The second was not hypothetical. `WATCHED` was short by eight, and
+`is_intake_register_header` was **already being driven and already missing from
+the list** — the *"one unwatched conversion away"* that round 10 declared as a
+future risk had already happened. `WATCHED` is 16 → 24.
+
+---
+
+## 4. The corpus
+
+Round 10's review:
+
+> *"No `DRIFT` entry carries a row through a dict or an attribute … That is the
+> sentence round 9 wrote about `fold = squash`, with a different noun."*
+
+Fourteen new `DRIFT` entries, each quoting the review line it comes from.
+Nine answer round 10's charge:
+
+| entry | shape |
+|---|---|
+| `D34` | a dict built in the SAME function |
+| `D35` | a dict a file-local function RETURNED |
+| `D36` | a LIST OF DICTS, indexed |
+| `D42` | a LOOP over a list of tables |
+| `D37` | an OBJECT ATTRIBUTE, set in `__init__` |
+| `D38` | the FOUR-LINK chain `bin/perry_store.py` actually writes |
+| `D39` | a table handed over by `yield` |
+| `D40` | a dict-carried row, SCALAR on one cell |
+| `D41` | a dict-carried row folded through `ops.norm` |
+
+Five more came out of the mechanical sweep and the round 11 review (§ 1.5):
+
+| entry | shape |
+|---|---|
+| `D43` | a table RE-YIELDED by `yield from` |
+| `D44` | a table reached through a METHOD of a file-local class |
+| `D45` | a table bound by a COMPREHENSION generator |
+| `D46` | a tuple unpack whose element is one CELL |
+| `D47` | a row written INTO a dict, then folded out of it |
+
+Five new `CLEAN` controls. The first two are the reason the entries above are
+not a key-name allowlist; the last three are criterion 4's own direction, and
+they exist because the round 11 review showed the corpus could not see it
+(§ 1.5):
+
+| entry | shape |
+|---|---|
+| `C13` | a dict of VALUES, folded by `squash` — silent |
+| `C14` | a generator yielding a dict of VALUES — silent |
+| `C15` | a DECOY ATTRIBUTE beside a real header row — silent |
+| `C16` | a DECOY KEY beside a real header row — silent |
+| `C17` | a table dict indexed by a VARIABLE key — silent |
+
+`D39` and `C14` differ only in whether what went into the dict came off a row.
+That is the provenance the whole design is stated over, and it is now planted on
+both sides.
+
+**The three fractions, computed:**
+
+```
+DRIFT       caught  : 47 of 47
+CLEAN       flagged : 0 of 17
+SECOND_RULE caught  : 0 of 41 (+2 the reviews do not name)
+```
+
+`0 of 41` on `SECOND_RULE` is unchanged and is round 9's accepted ruling.
+
+---
+
+## 5. Mutations — thirty-one, all red
+
+Each anchored by LINE, asserted against the exact old text before replacing,
+run in a **fresh interpreter**, with `__pycache__` cleared and the clock walked
+past the next whole second on **both** sides, and restored from the WHOLE
+original text with the md5 verified. Every restore printed `MATCHES`.
+
+**[review correction 2, and again in the delta pass] A table published against
+a state older than itself — for the THIRD time on this row.** Round 10's
+predated `D32`/`D33`; round 11's first draft predated `D42`; and correction 1
+inserted fourteen lines into `test_header_index_is_the_only_fold.py`, so
+R11-20, R11-21 and R11-22 named lines 435, 126 and 270 while the anchors had
+moved to 449, 140 and 284 — **stale by exactly +14, the lines the correction
+itself added.** Twice a corpus, once a line number; all three times the *entry*
+was fixed by hand and the *pattern* was not.
+
+**So the line number is no longer an input.** Every mutation below is
+identified by the exact TEXT of the line or block it replaces; the harness
+looks the line number up at run time and asserts it is unique, which is how
+`R11-17`'s anchor was caught being ambiguous across three `IfExp` branches. A
+shift can no longer make this table stale, and the number in each row is
+measured in the run that produced the result beside it. That is the fix; the
+three corrected offsets are a consequence of it.
+
+All thirty-one below were re-run in one pass on `87c920d`, against the
+47-entry `DRIFT` corpus and the 17-entry `CLEAN` corpus, with every restore
+md5-verified.

+| R11-23 | `header_rule.py:881` call every carried site static | `test_the_uncovered_remainder_is_the_measured_one` |
+
+**Thirty-one mutations, all red. Thirteen single-entry**: ten reddening one
+`DRIFT` entry (R11-3, 6, 7, 10, 17, 24, 25, 26, 27 and **R11-31**, which the
+round 11 review asked for — `D44` pins a branch that is single-entry and had no
+row saying so) and three flagging one `CLEAN` entry (R11-28, 29, 30), the three
+that make criterion 4 measurable rather than asserted.
+
+**No mutation of the catching direction flagged a `CLEAN` entry, and no
+mutation of the over-firing direction let a `DRIFT` entry escape.** Those are
+two different claims and until the delta pass only the first one had a
+measurement behind it.
+
+The round 11 reviewer could not verify 9 of the 23 rows in the first draft of
+this table, because it named each mutation and not the line it was made at, and
+substituted an exhaustive plant sweep and a twelve-branch hunt of its own —
+which is what produced the corrections in § 1.5 and § 2.3. With anchors, five
+of those nine replayed from the table alone on the next pass.

+
+## 6. Baselines — runner AND tree
+
+| runner | tree | modules | tests | failures |
+|---|---|---|---|---|
+| `bash tests/run` | `4c2f07a`, the merged tree this round started from | 102 | **3034** | 3 |
+| `bash tests/run` | `9d00f1b`, this round's code tip | 102 | **3036** | 3 |
+| `bash tests/run` | `9d00f1b`, a second run after restoring § 9's four files | 102 | **3036** | 3 |
+| `bash tests/run` | `3210248`, the tip after the three review corrections | 102 | **3036** | 3 |
+| `bash tests/run` | `f22fc3f`, the tip after the delta pass — **two hours later** | 102 | **3036** | **4** |
+| `bash tests/run` | **`4c2f07a` again, the base tree, at the same hour** | 102 | **3034** | **4** |
+| `python3 -m unittest … test_header_index_is_the_only_fold.py` | `3210248` | — | 10 | 0 |
+| `python3 -m unittest … test_one_header_rule.py` | `3210248` | — | 13 | 0 |
+| `python3 -m unittest … test_row_integrity.py` | `3210248` | — | 33 | 0 |
+| `python3 -m unittest … test_header_rule_harness.py` | `3210248` | — | 13 | 0 |
+
+3034 → 3036 is this round's two new tests, both in
+`test_header_index_is_the_only_fold.py` (8 → 10). The count on `4c2f07a`
+matches the PMO's and the round 10 reviewer's measurement of that tree exactly.
+
+**The failure count moved from 3 to 4 during this session, on an UNCHANGED
+tree, and the last row of that table is the proof it is not this round's.** A
+fresh `git archive` export of `4c2f07a` — the tree this round started from,
+with none of its code — run through the same `bash tests/run` at the same hour
+gives the **same four failures**. The new one is `test_contract_key_parity`,
+two assertions about `conformance.in_progress_with_no_live_run[]`, which was an
+EMPTY collection at 04:51 and is not any more: a row on this project's own
+board crossed the "in progress with no live run" threshold while the session
+ran. That is a **third** data-dependent failure on top of the two this row has
+always carried, and the brief's warning — *"do not take a live-board failure
+count from any brief as fixed"* — is now measured rather than quoted.
+
+A fifth failure appeared in one run only,
+`test_host_support.TestOpenCodeDispatchLimit.test_concurrent_mixed_registers_do_not_exceed_global_cap`.
+It is green in isolation and absent from the next full run: a load flake in a
+concurrency test, on a machine that had just finished a 213-mutant sweep.
+Recorded, not carried.
+
+The three original failures are the same three names in every run, unchanged:
+
+- `test_diagnose.DecisionsAreCountedPerRecordNotPerMention.test_the_queue_register_reconciles_with_the_queue_on_this_repository`
+- `test_diagnose.TestUserLoadFindings.test_perry_itself_passes_its_own_id_checks`
+- `test_kr_progress_provenance.TestBothOfTodaysWrongReadingsFlip.test_no_current_in_the_payload_claims_to_be_a_measurement`
+
+Two of them are data-dependent on board state and one on a row's Next action
+prose, so this count is stated for these two trees and not carried forward.
+
+`offenders_by_symbol` on the live tree, best of three in one process:
+**1.83s** against round 10's **1.48s**, best of three in one process each.
+`test_header_rule_harness` is 152s against round 10's 156s.
+
+---
+
+## 7. What was NOT done, and what is not proven
+
+Restated from scratch, because round 10's list was failed for the content of
+one entry rather than its bookkeeping. Round 10's thirteen map onto these; the
+one that changed is limit 1.
+
+1. **A header row whose producing chain crosses a MODULE boundary is not
+   resolved statically, and there are eleven such sites.** This replaces round
+   10's limit 1, which said the uncovered set was empty and described the
+   mechanism as a module boundary when the failing case had none. Measured: of
+   the 17 carried sites, the **six** inside `bin/perry_store.py` resolve; the
+   **eleven** in `bin/perry-task`, `bin/perry-tasks` and `bin/perry_md_store.py`
+   are each rooted in a call into `perry_store` or into a `Board` defined in
+   another module. `_RowLocals` is file-local by construction; cross-module
+   dataflow is a type checker's job.
+2. **`_paths` has no comprehension branch, and that is a FILE-LOCAL hole.** A
+   path does not travel through a comprehension's element expression, so
+   `tables()` at `bin/perry-lint:194` —
+   `[(h, [c for c, _ in r]) for h, r in tables_with_lines(section)]`, both
+   functions in that same file — hands its header row on invisibly. **Three of
+   the eight uncovered sites are this and not limit 1**, and they are closable
+   by the machinery this round already built. Found by the round 11 review;
+   `_bind_element` IS called for a comprehension's generators (`D45`), so it is
+   specifically `_paths` that stops at the element expression.
+3. **The remainder neither half covers is 8**, listed by name in § 2.3 and
+   recomputed by a named test. It is not zero and this round does not claim it
+   is — and **five of the eight, not eight, are the cross-module limit.**
+4. **The `carried` half of the census is a SPELLING**, `CARRIED_KEYS =
+   ("header", "headers", "hdr")`. It is used only to COUNT, never by
+   `offenders_by_symbol`, and it is documented as such at its definition — but
+   a census that undercounts overstates coverage, so a row held under a fourth
+   key name is uncounted. The `convert` half (59 of the 76 sites) is
+   spelling-free.
+5. **The dynamic half measures FUNCTION entry, not line execution.** A plant on
+   a branch the workload does not take, inside a function it does enter, is
+   counted as covered and would not be. A line-level trace of the same workload
+   returns the same remainder today (§ 2.2), so nothing is hiding behind the
+   coarser question — but that is a measurement, not a guarantee.
+6. **A second RULE — a reader that invents its own fold — is invisible to the
+   static net by construction.** That is `SECOND_RULE`, 41 planted shapes
+   asserted to escape, covered by
+   `test_every_decorated_header_cell_reached_header_index`. Round 9's ruling
+   that `0 of 41` is acceptable under option C is carried, not re-litigated.
+7. **A rebinding through a container (`FOLDS["k"] = squash`) and a function that
+   RETURNS the rule (`def picker(): return squash`) are still not resolved as
+   aliases.** Round 10's limit, unchanged; both are a second-rule shape by
+   another road.
+8. **`WATCHED` records bare function names.** `header_language` exists in both
+   `bin/perry-goals` and `bin/perry-task`, so one entry can be satisfied by
+   either. The converse check in § 3 matches by file as well as name, so the
+   equality is not fooled — but the forward check
+   (`test_every_reader_this_module_claims_to_watch_actually_folds_one`) still
+   is. Recorded by the round 10 review; not load-bearing today.
+9. **`viewer/parsers.py § parse_decisions`** is still a live instance of the
+   scalar second-rule class and still dead code. Agreed out of scope.
+10. **The write side, localized headers and non-Python readers are not audited.**
+11. **Eleven branches were deleted for being unmeasured** (§ 1.5) — the ten the
+    hand sweep found plus `ast.Set`. Each was dead on this tree; a future reader
+    that writes `d.setdefault("header", row)` or `tables[1:]` would escape until
+    someone plants it. That is a deliberate trade — an unmeasured half is what
+    failed round 8 — and it is stated here so the next round can widen it *with*
+    an entry rather than without one.
+12. **`test_the_row_splitter_half_is_owned_by_criterion_3` still asserts half
+    its docstring**: it checks `SPLIT_RE` and not that the scan covers `bin/`
+    and `viewer/`. Carried from round 10.
+13. **No reader was driven end-to-end from `argv`.** Round 8's four-CLI
+    byte-identical differential is carried, not re-measured.
+14. **`bash tests/run` writes Perry state into the repository it runs in**
+    (§ 9). Observed, reproduced under control, confirmed independently by the
+    round 11 reviewer in its own export, and filed as `TASK-249`. Not this row.
+15. **The census's `carried` half has an ATTRIBUTE branch that is unexercised
+    — kept, where `ast.Set` was deleted, and the reasons are different.** All
+    seventeen live carried sites are subscripts, so neutralising the attribute
+    branch of `header_sites` moves nothing (§ 1.5). The round 11 review
+    confirmed the 0 of 17 and ruled that declaring this one is right where
+    deleting `ast.Set` was right, and the distinction is worth stating because
+    "survives its own deletion" is not by itself a verdict:
+
+    - `ast.Set` is **unreachable in principle** — a row is a list, a list is
+      not hashable, so no row can ever be an element of a set literal. Nothing
+      would pin it, ever. Deleted.
+    - The census's attribute branch is **reachable in principle** — a reader
+      that holds its header row on an attribute is ordinary Python, this tree
+      simply has none today — and its detection-side sibling is pinned by
+      `D37`. Kept and declared, so the census does not silently under-report
+      the day one appears.
+
+    An unexercised branch of the MEASUREMENT is exactly the kind of thing this
+    row has been failed for leaving unsaid, which is why it is here and not
+    only in a commit message.
+16. **A declared bound is not a covered class, and there is still a bound.**
+    The first sweep declared, in writing, that it did not mutate individual
+    conjuncts — and that bound was hiding criterion 4's failure mode at
+    `:659`, which the round 11 review found by running exactly the sweep the
+    bound excluded (§ 1.5). The bound is now smaller, not gone: the delta sweep
+    does not mutate constants, operators, comparison directions or f-string
+    contents, does not cover
+    `tests/test_header_index_is_the_only_fold.py`, and probes over-firing only
+    against the corpus — so a false positive on a shape nobody planted is
+    invisible to it. **The next round should assume this bound hides something
+    too**, and the way to find out is to run the sweep it excludes rather than
+    to trust the sentence.
+17. **Twenty-six mutants of the delta sweep are green and only four of them
+    were probed** for over-firing with constructed decoy shapes (§ 1.5). One of
+    the four produced a false positive and is now `C17`. The other twenty-two
+    are unexercised, not proven harmless, and this document does not say
+    otherwise.
+
+---
+
+## 7a. What the round 11 review verified independently
+
+Recorded because it is stronger evidence than anything this document could
+produce about itself, and because the next round should not re-run it:
+
+- **The census's static verdict was validated EXHAUSTIVELY**, by planting at
+  **all 76 sites one at a time**: `offenders_by_symbol` agreed with the
+  `static` flag **76 of 76**.
+- **The remainder reproduces on the reviewer's own `sys.settrace`** — 8 by
+  function entry and 8 by line execution, the same eight members — and round
+  10's **20** reproduces exactly.
+- **The reconciliation with the round 10 reviewer's twelve was checked**: 13
+  carried sites in 12 names.
+- **"Provenance, not a key-name list" survived adversarial testing**: a dict
+  keyed `zulu` holding a row is CAUGHT, a key literally named `header` holding
+  non-row values is silent, and `CARRIED_KEYS` is never read by
+  `offenders_by_symbol`.
+- **Nine of the 23 mutations in this document's first draft could not be
+  verified from it**, because the table named each mutation and not the line it
+  was made at. The reviewer substituted the exhaustive plant sweep and a
+  twelve-branch hunt of its own — which is what produced corrections 1 and 3.
+  § 5 now carries the anchor for every row.
+
+---
+
+## 8. Corrections to round 10's result, and to this one
+
+- **R10-2 reddens EIGHT corpus entries, not the six § 3.1 lists.** `D32` and
+  `D33` are also alias-resolution dependents; the table predated them. The
+  review is right and the correction is made here rather than in place, because
+  this document supersedes that section.
+- **§ 4.2's first row overstated the static half.** It claimed
+  `offenders_by_symbol` sees *"the rule applied to a row a local dataflow
+  reaches, under any alias"*. It did not: a dict-carried row is a local
+  dataflow and was not seen. It is now, and § 7 limit 1 states what is left.
+- **§ 7 limit 1 is withdrawn in full** and replaced by § 7 limits 1 and 2 above.
+- **§ 7 limit 11** (*"this branch is not rebased on `main`"*) was already
+  untrue of the tree the reviewer measured; the PMO's merge post-dates the
+  document.
+
+---
+
+## 9. Findings this round produced
+
+1. **`WATCHED` was short by eight, not by nothing**, and one of the eight —
+   `is_intake_register_header` — was already being driven. The list claimed
+   fewer readers than the module actually watched, which is the mirror image of
+   round 8's finding that it claimed more.
+2. **Eleven branches of this round's own first draft survived their own
+   deletion** and are deleted, and **five more were unpinned detection branches
+   that are now planted** (§ 1.5). The hand sweep found ten of the eleven; the
+   round 11 review found `ast.Set` and the `YieldFrom` step that the hand sweep
+   never reached, and the mechanical sweep built in answer to that found four
+   more. The lesson is not "sweep harder" — it is that **a candidate list a
+   human writes is a claim about their own code, and this row has been failed
+   three times for claims wider than their measurement.** The candidate list now
+   comes from `git diff`.
+
+   And the second half of the same finding, which took two more passes to
+   see: the sweep that replaced my hand list came with a **declared bound**,
+   and the bound was where criterion 4's failure mode was. A bound written
+   down honestly is still an uncovered class. The only thing that closed it
+   was running the sweep the bound excluded — which found a second instance of
+   the same defect that nobody had asked about.
+
+4. **A live-board failure count is not a property of the tree.** This session
+   measured `4c2f07a` at 102/3034/**3** at 04:51 and at 102/3034/**4** at
+   07:10, with no change to the tree in between — the difference is a board row
+   ageing past a conformance threshold. Any round that carries a failure count
+   forward without re-measuring the SAME tree at the SAME hour is carrying a
+   number that has already moved. Two of this row's failures were known to be
+   data-dependent; this is a third, and it is the one that shows the count
+   itself is a measurement with a timestamp.
+
+5. **Three times on this row a table has been published against a state older
+   than itself** — round 10's mutation table predated `D32`/`D33`, round 11's
+   first draft predated `D42`, and round 11's own corrections shifted three
+   anchors by +14 while the table still named the old lines. Each time the
+   entry was corrected and the mechanism was not. It is fixed structurally now:
+   § 5's anchors are the exact TEXT of what is replaced, the line number is
+   looked up at run time and asserted unique, and the harness refuses an
+   ambiguous anchor — which is how `R11-17` was caught matching three
+   different `IfExp` branches.
+3. **`bash tests/run` writes Perry state into the repository it runs in, and
+   it is reproducible.** After this session's baseline run, `git status` in the
+   worktree showed four tracked files modified — `.perry/events.jsonl`,
+   `perry/BOARD.md`, `perry/intake.jsonl` and
+   `perry/journal/2026-08/2026-08-30.md` — all at the same second, carrying an
+   `intake-sweep` event with `"actor": "agent"` that discharged one board row
+   into the journal.
+
+   A second run left them alone, so the write was checked properly rather than
+   assumed: the four files were restored to their committed bytes (md5s
+   recorded), `bash tests/run` was run again, and **the same four files moved
+   again with the same one-row sweep and a new timestamp**. The no-op second
+   run is the sweep being idempotent — after the first one there is nothing
+   left to discharge — not the write being a one-off.
+
+   **Independently confirmed by the round 11 reviewer**, which saw three
+   tracked files move after `bash tests/run` in its own export — a third
+   observation of the same behaviour. Filed as `TASK-249`.
+
+   Restored again afterwards; the four md5s match their committed bytes and
+   nothing from them is in this branch. Which test does it was not
+   investigated: it is outside this row. Recorded because a reviewer who runs
+   `bash tests/run` inside a worktree rather than on a `git archive` export
+   will see these four files move and must not read them as the round's work —
+   and because two of this suite's three carried failures are data-dependent on
+   board state, which this write touches.

+> option C`, which binds.
+> Under review: `901d89e`, tip of `coding/task-050-header-index`, in the
+> read-only worktree at `scratchpad/review-050r11`. The code at `901d89e` is

+> tree. No write-side Perry tool was run against any live checkout. No
+> identifier was minted. Every file I wrote is prefixed `rjr11`.
+> The reviewed worktree was re-hashed against `git ls-tree -r HEAD` at the end:
+> **722 files, 0 mismatches**, `git status --porcelain` empty,
+> `git ls-files -o --exclude-standard` empty.
+
+**The number this round turns on is right, and I rebuilt it twice with my own
+instrument.** The remainder is **8 of 76**, by function entry and by line
+execution, with the same eight members as `UNCOVERED`. I then went one level
+below that and validated the census's *static* verdict exhaustively: I planted
+`[squash(_c) for _c in <the site's own expression>]` at all **76** sites, one at
+a time, and `offenders_by_symbol`'s answer agreed with `header_sites()`'s
+`static` flag **76 times out of 76**. The static half of the measurement is not
+a self-report; it is exactly what it claims to be.
+
+**The dict-carried case is genuinely closed, and the "provenance, not a
+key-name list" framing survives adversarial testing.** A row put into a key
+named `zulu` — a name in no list anywhere — is CAUGHT; a value put into a key
+named `header` is silent. `CARRIED_KEYS` is a census spelling and
+`offenders_by_symbol` never reads it.
+
+**`WATCHED` no longer survives its own deletion, in both directions**, and the
+"short by eight" claim is true: I measured, under round 10's own workload, that
+`is_intake_register_header` was already being driven and already absent from
+round 10's sixteen-name list.
+
+I found three defects, all recorded below, none of which I judge a FAIL: the
+round misdescribes the *mechanism* of 3 of its 8 declared uncovered sites (they
+are file-local, not cross-module); the mutation table omits `D42` from five rows
+so "nine single-entry mutations" is eight; and two branches of the round's own
+new machinery still survive their own deletion, which its eighteen-probe sweep
+did not reach.
+
+---
+
+## THE RULING THE BRIEF ASKS FOR
+
+### A measured, listed remainder of 8 out of 76 DOES discharge the amendment.
+
+Round 10's ruling — which I do not re-litigate — accepted that a runtime watch
+can close a static hole. The rule it laid down for doing so was: *a dynamic
+cover discharges a static hole only if the round MEASURES which sites it reaches
+and STATES the remainder.* That is a rule about **knowing the number**, not
+about the number being zero, and the round 10 FAIL was for asserting `empty`
+against a measured twelve.
+
+Round 11 supplies the measurement and I verified it three ways:
+
+1. The **enumeration** is 76 sites — 59 `convert` (an argument of
+   `header_index`/`header_keys`, derived from the blessed call and therefore
+   spelling-free) and 17 `carried`. I reproduced 59/17, 51 convert-functions,
+   17 carried-functions.
+2. The **static verdict** is not asserted: 76 of 76 sites' verdicts match what
+   an actual plant on that site's own expression does (§ 3 below).
+3. The **dynamic reach** is measured, not claimed, and the remainder recomputes
+   to 8 under a profiler I wrote myself and under a line-level trace, with the
+   same eight members (§ 2).
+
+And the remainder is asserted by a live named test that fails in **both**
+directions — grow it and it goes red, shrink it and it goes red — which I
+confirmed by three separate mutations (R11-21, R11-22, R11-23), one neutralising
+the static half of the measurement and one the dynamic half.
+
+Against that: it is true that the amendment's own sentence is falsifiable on a
+live production file. I planted a bare dict-comprehension second rule at
+`bin/perry-lint § check_cross_file` and all three header modules stayed green
+(§ 6). But that site is one of the eight, named by file and function in
+`UNCOVERED`, and its being listed is precisely what round 10 was failed for not
+doing. Requiring the number to be 0 would require either whole-project
+interprocedural analysis — which the amendment rejects by name — or driving
+three CLIs end-to-end from `argv` and constructing a `Board` and a `ctx` for the
+other five, which is a workload-engineering task the amendment nowhere asks for.
+
+**If a future round wants a smaller number, the honest target is 5, not 0**:
+the three `bin/perry-lint` sites are closable statically with one more `_paths`
+case (§ 1), and the remaining five are genuinely rooted in a cross-module call.
+I would not fail a round for 8, and I would fail one for stating a number it did
+not measure.
+
+---
+
+## Finding 1 — the structural explanation for 3 of the 8 is wrong, and the fix is file-local
+
+This is the round's principal defect and it is the same species as round 10's,
+one rung smaller: a declared limit that misdescribes what it declares.
+
+`UNCOVERED`'s docstring and § 2.3 both say:
+
+> *"All eight are rooted in a call into ANOTHER MODULE — `perry_store.markdown_tables`,
+> `perry_store.intake_table`, `board.task_tables()` — which is the
+> interprocedural step `tests/header_rule.py` is file-local against by
+> construction."*
+
+For five of the eight that is true and I checked each one. For the three
+`bin/perry-lint` sites it is false. `bin/perry-lint:1376` is:
+
+```python
+for header, rows in tables(strip_comments(board.read_text())):
+    got = header_index(header)
+```
+
+and **both** `tables` (`bin/perry-lint:194`) and `tables_with_lines`
+(`bin/perry-lint:209`) are defined in `bin/perry-lint`. There is no module
+boundary in that chain. What defeats the static half is that `_paths` has no
+comprehension branch, so `return [(h, [c for c, _ in r]) for h, r in
+tables_with_lines(section)]` carries nothing.
+
+Reproduced on a synthetic file with **no cross-module call anywhere**
+(`scratchpad/rjr11/probe/rjr11_lint.py`):
+
+```
+L1_lint_shape_file_local       ESCAPED  []
+L2_no_comprehension_link       CAUGHT   ['bin/pr.py:12: [squash(c) for c in header]', ...]
+```
+
+`L1` is `perry-lint`'s exact four-link shape, all file-local. `L2` is the same
+file with the one comprehension link replaced by a plain `return
+tables_with_lines(section)` — and it is CAUGHT. The escape is the comprehension,
+not the module.
+
+**Why this is recorded and not a FAIL.** It misstates *why* three entries are
+open, not *which* or *how many*. The eight are named by file and function, the
+count is right, and the guard that recomputes it is red in both directions. The
+downstream harm is bounded and specific: a next round reading § 2.3 will believe
+these three are behind the widening the amendment rejects, when they are one
+`_paths` case away. § 2.3 and the `UNCOVERED` docstring should say so.
+
+*(A smaller sibling: § 7 limit 1 says the eleven unresolved carried sites are
+"in `bin/perry-task`, `bin/perry-tasks` and `bin/perry_md_store.py`". Ten are.
+The eleventh is `bin/perry_store.py:533 § plan`, in the file the limit says
+resolves — seven carried sites live in `perry_store.py` and six of them resolve.
+§ 2.3 lists it correctly. Bookkeeping, not substance.)*
+
+---
+
+## What I verified independently, with the commands
+
+### 2. The remainder is 8, and I rebuilt it without reusing `Reach` or `UNCOVERED`
+
+`scratchpad/rjr11/rjr11_reach.py` runs the module's own `parse_everything()`
+under my own `sys.settrace`, collecting both `call` and `line` events, and
+recomputes the difference against `header_sites()`:
+
+```
+sites 76 static-blind 27
+
+REMAINDER by function-entry: 8
+   ('carried', 'bin/perry-task',        '_cmd_list_from_board')
+   ('carried', 'bin/perry_md_store.py', 'plan')
+   ('carried', 'bin/perry_store.py',    'plan')
+   ('convert', 'bin/perry-lint',        'check_cross_file')
+   ('convert', 'bin/perry-lint',        'check_reviews')
+   ('convert', 'bin/perry-lint',        'check_verification')
+   ('convert', 'bin/perry-task',        'task_projection_row')
+   ('convert', 'bin/perry_store.py',    'plan')
+
+REMAINDER by line-execution: 8   (identical members)
+stated UNCOVERED: 8
+func == stated: True
+```
+
+**The reconciliation to round 10 also reproduces, exactly.**
+`scratchpad/rjr11/r10w/rjr11_rem10workload.py` — round 11's tree (so
+`static-blind 27`, as § 2.2 states) driven by round 10's `parse_everything()`:
+
+```
+REMAINDER (func-entry), r11 tree + r10 workload: 20
+REMAINDER (line-level): 20   same members: True
+```
+
+**20, on the nose**, and the line-level trace agrees. And the twelve:
+
+```
+carried sites in functions round10's workload never enters: 13
+distinct names: 12
+['_cmd_list_from_board', '_task_sections', 'ask_plan', 'ask_section_shape',
+ 'ensure_columns', 'ensure_section_columns', 'find', 'plan',
+ 'refuse_foreign_risk_table', 'risk_plan', 'risk_section_shape', 'task_tables']
+```
+
+**13 sites in 12 names — the round 10 reviewer's twelve, exactly, with `plan`
+standing for two files.** Nine of them are now driven.
+
+*(One wording slip: § 0.3 says the 20 was measured "under round 10's tree and
+workload". Under round 10's actual tree — where the static half is round 10's,
+`static-blind 36` — I measure **25**, not 20. § 2.2 states it correctly as
+`9d00f1b` plus round 10's workload, and pins `static-blind=27` in every row. § 0
+is loose where § 2.2 is right.)*
+
+### 3. The static verdict is validated exhaustively, not asserted — 76 of 76
+
+This is the check that decides whether the number can hide anything.
+`scratchpad/rjr11/rjr11_plantall.py`: for each of the 76 sites, insert
+`_rjprobe = [squash(_c) for _c in (<that site's own expression>)]` immediately
+after the enclosing statement, in a mini root holding only that file, and ask
+`offenders_by_symbol` whether the planted line is reported.
+
+```
+sites: 76
+agree: 76 of 76
+static True: 49  plant CAUGHT: 49
+```
+
+(My first pass reported 3 mismatches at `viewer/parsers.py`; all three were my
+harness un-parenthesising an `IfExp` into a syntax error. With a `compile()`
+guard and parentheses added, agreement is total. Recorded because a reviewer's
+own artefact reported as a finding is the failure mode this row keeps meeting.)
+
+So `static=True` means precisely what the round says it means, and the 27
+static-blind sites are the real ones.
+
+### 4. "Provenance, not a key-name list" — tested adversarially, and it holds
+
+Rounds 5 through 9 were failed twice for allowlists, so this was the claim I
+attacked hardest. `scratchpad/rjr11/probe/rjr11_probe.py`, one plant at a time
+into a mini root:
+
+```
+A_odd_key_local_dict     CAUGHT   t = {"zulu": split_row(l)};  [squash(c) for c in t["zulu"]]
+B_odd_key_returned       CAUGHT   t = table_of(l);             [squash(c) for c in t["zulu"]]
+C_odd_attr               CAUGHT   t = T(l);                    [squash(c) for c in t.zulu]
+D_header_key_values      ESCAPED  t = {"header": [rec.get("status"), ...]}; [squash(c) for c in t["header"]]
+E_header_key_literal     ESCAPED  t = {"header": ["a", "b"]};   [squash(c) for c in t["header"]]
+F_control_direct         CAUGHT   [squash(c) for c in split_row(l)]
+G_control_values         ESCAPED  [squash(x["status"]) for x in recs]
+```
+
+A key name nothing has ever heard of is caught; the key name `header` holding
+values is silent. `grep -rn CARRIED_KEYS tests/ bin/ viewer/` confirms the three
+census names are read only inside `header_sites()` and never by
+`offenders_by_symbol`. **This is provenance.** `ROW_NAMES` stays deleted.
+
+### 5. The reviewer's exact plant, replayed
+
+`bin/perry_store.py:855`, one line, bare `squash`, no alias:
+
+```
+$ python3 -c "... offenders_by_symbol('.')"
+['bin/perry_store.py:855: [squash(c) for c in header]',
+ 'bin/perry_store.py:855: squash(c)']
+
+test_header_index_is_the_only_fold  Ran 10  FAILED (failures=1)
+    test_the_static_net_is_the_one_that_sees_dead_code
+test_one_header_rule                Ran 13  FAILED (failures=2)
+    test_nothing_outside_header_index_maps_squash_across_a_row
+    test_value_normalizers_are_not_flagged
+test_row_integrity                  Ran 33  OK  (not its criterion)
+```
+
+Three named tests, as claimed.
+
+### 6. The dynamic cover is real where it is claimed
+
+I planted `[squash(_c) for _c in table["header"]]` inside `bin/perry-task §
+find` — static-blind, dynamically covered — and
+`test_every_fold_of_a_header_cell_came_from_header_index` goes **RED**
+(`stray == ['<listcomp>']`), with `offenders_by_symbol` still `[]`. So the
+runtime half genuinely carries the sites the static half cannot see.
+
+Conversely, at `bin/perry-lint § check_cross_file` — one of the declared eight —
+`got = {squash(c): i for i, c in enumerate(header)}` leaves
+`offenders_by_symbol` `[]` and all three header modules **OK**. That is the
+remainder doing exactly what the round says it does, at a site the round names.
+
+*(A caution for the next round, from my own harness: when I planted after a
+`return` statement, the plant was unreachable and the watch stayed green. That
+is § 7 limit 4 — function entry is not line execution — made visible. The
+line-level trace in § 2 returns the same 8 today, so nothing is hiding behind
+it, but the limit is real.)*
+
+### 7. `WATCHED`, both directions
+
+| mutation | result |
+|---|---|
+| **R11-18** delete `"cmd_intake_write"` (the round 10 reviewer's own deletion) | **RED** `test_watched_is_exactly_…` |
+| **R11-19** drop `"is_intake_register_header"` (convert-and-forget) | **RED** `test_watched_is_exactly_…` |
+| *my own*: ADD a bogus name `"rj_bogus"` | **RED** ×2 (`test_watched_is_exactly_…`, `…_actually_folds_one`) |
+| `self.drive_the_carried_row_readers()` → `pass` | **RED** ×3 modules-worth (9 failures) |
+| `self.drive_intake_write()` → `pass` | **RED** (4 failures) |
+
+**The "short by eight" is true and I measured its most interesting half
+independently.** Running *round 10's* `parse_everything()` (from `4c2f07a`)
+against round 11's `Watch` and `header_sites()`:
+
+```
+round10 workload, converted readers folded through: 17
+round10 WATCHED: 16
+in workload but NOT in round10 WATCHED: ['is_intake_register_header']
+in round10 WATCHED but not in workload: []
+```
+
+The *"one unwatched conversion away"* round 10 declared as a future risk had
+already happened, exactly as § 3 says. 16 → 24; the eight added are
+`is_intake_register_header`, `is_user_register_header`, `check_header`,
+`ensure_columns`, `ensure_section_columns`, `task_section_headings`,
+`replace_row`, `canonical_of`.
+
+### 8. The corpus, and the two new controls really discriminate
+
+`measure()` on a `git archive` export:
+
+```
+DRIFT 42  CLEAN 14  SECOND_RULE 41
+{'drift_escaped': [], 'clean_flagged': [], 'second_rule_caught': []}
+```
+
+42/42, 0/14, 0/41. I read `D34`, `D36`, `D38`, `D39`, `D42`, `C13`, `C14`
+against the round 10 review's own escape list; each quotes the line it comes
+from and none was invented to be easy.
+
+**`C13` and `C14` are not controls that cannot fail.** Swapping only what goes
+into the dict — value → row, key name and shape unchanged — flips both:
+
+```
+C13_as_shipped     silent    d = {"status": record.get("status","")};  squash(d["status"])
+C13_row_instead    CAUGHT    d = {"status": split_row(record)};        squash(d["status"][0])
+C14_as_shipped     silent    yield {"status": r.get("status","")};     [squash(d["status"]) ...]
+C14_row_instead    CAUGHT    yield {"status": split_row(r)};           [squash(c) ...]
+```
+
+and `D39` rewritten with the key `qq` instead of `header` is still CAUGHT. The
+corpus discriminates on provenance, not on spelling.
+
+### 9. Mutations — eight of the code mutations reproduced independently, all red
+
+Run through my own fast corpus probe (each entry planted alone into a mini root;
+validated against the full `measure()` on the unmutated tree — both report 0
+escaped, 0 flagged, 0 second-rule caught).
+
+| mutation | my measurement | claimed |
+|---|---|---|
+| attribute carries nothing (R11-3) | **`D37` only** | D37 only ✓ |
+| `yield` is not a producer (R11-4) | **`D39` only** | D39 only ✓ |
+| `out.append(...)` fills nothing (R11-5) | `D38` **and `D42`** | D38 only — **under-reported** |
+| tuple UNPACK carries no paths (R11-6) | **`D38` only** | D38 only ✓ |
+| loop targets carry no paths (R11-7 + R11-12) | `D39`, `D42` | D39 only / D42 only ✓ |
+| an `IfExp` carries nothing (R11-17) | **`D38` only** | D38 only ✓ |
+| a call carries nothing from its callee (R11-16) | `D35 D36 D37 D38 D39` **+ `D42`** | without D42 — under-reported |
+| the path fixpoint runs once (R11-8) | `D37 D38` **+ `D42`** | D37 D38 — under-reported |
+
+Plus, from my branch hunt: `source()` no longer consults `_paths` (R11-1) reddens
+seven **+ `D42`**, and a dict literal carrying nothing (R11-2) reddens seven
+**+ `D42`**.
+
+**No mutation flagged a `CLEAN` entry and none made a `SECOND_RULE` entry
+caught**, in any run.
+
+**Finding 2 — the mutation table omits `D42` from five rows**, and one
+consequence is that **"nine single-entry mutations" is eight**: R11-5 reddens
+`D38` and `D42`. `D42` was added late (§ 1.5 says so — it came out of the
+eleventh survival probe), and the table evidently predates it, exactly as round
+10's R10-2 predated `D32`/`D33` — the very error this round corrects in § 8.
+Every discrepancy is in the safe direction: the machinery is pinned by *more*
+corpus entries than the table claims, never fewer.
+
+**R10-2's correction verified:** `target = self._alias_target(...)` → `None`
+reddens **eight** entries, `D25 D27 D28 D29 D30 D31 D32 D33`. § 8 is right.
+
+**R11-1's honest exception verified:** it does *not* redden `D38`, because the
+tuple-unpack branch writes into `self.scope` directly. Reported rather than
+tidied, as § 5 says.
+
+### 10. Baselines — runner AND tree
+
+`bash tests/run` on a `git archive` export of `901d89e` (whose `tests/`, `bin/`
+and `viewer/` are byte-identical to `9d00f1b`), at
+`scratchpad/rjr11/base`:
+
+```
+102 modules · 3036 tests · 212.3s · 8 workers
+✗ 2 module(s) red
+```
+
+three failures, the same three names the round states:
+
+- `test_diagnose … test_the_queue_register_reconciles_with_the_queue_on_this_repository`
+- `test_diagnose.TestUserLoadFindings.test_perry_itself_passes_its_own_id_checks`
+- `test_kr_progress_provenance.TestBothOfTodaysWrongReadingsFlip.test_no_current_in_the_payload_claims_to_be_a_measurement`
+
+**102 / 3036 / 3 reproduced.** I did not re-run `4c2f07a`; the 3034 figure was
+measured by the round 10 reviewer and by the PMO, and 3036 − 3034 is exactly the
+two new tests in `test_header_index_is_the_only_fold.py` (8 → 10), which I did
+verify.
+
+**The write hazard reproduces.** Before that run I recorded the md5s of
+`.perry/events.jsonl`, `perry/BOARD.md` and `perry/intake.jsonl` in the export;
+all three changed afterwards. TASK-249 confirmed independently. Nothing was run
+in the reviewed worktree.
+
+---
+
+## Finding 3 — two branches of the round's own new machinery still survive their own deletion
+
+The round's strongest self-check is § 1.5: eighteen survival probes, ten deleted
+because nothing measured them. That work is real and I confirmed the deletions
+landed — `extend`/`update`/`insert`/`setdefault`, the iterable-wrapper,
+`.copy()`, `.get("k")` and `BoolOp` cases in `_paths`, the slice branch, the
+integer-subscript branch and the parameter path-carrying are all absent from the
+shipped `tests/header_rule.py`.
+
+**The sweep did not reach everything.** I ran twelve further neutralisations,
+each alone, checking the whole corpus *and* the live census (`sites`,
+`static-blind`, `offenders`) — the same two-sided criterion the round used:
+
+```
+baseline census (sites, static-blind, offenders): (76, 27, 0)
+
+YieldFrom step                     SURVIVES   escaped=[] flagged=[] census=(76, 27, 0)
+ast.Set in list/tuple literal      SURVIVES   escaped=[] flagged=[] census=(76, 27, 0)
+_bind_element scope add            pinned     census=(76, 28, 0)
+unpack `() in sub_p` half          pinned     escaped=['D38']
+pos: on a literal                  pinned     escaped=['D38','D39']  census=(76, 31, 0)
+elem on a literal                  pinned     escaped=['D36']        census=(76, 29, 0)
+Subscript elem fallback            pinned     escaped=['D36','D38']  census=(76, 35, 0)
+self.header -> class rpaths        pinned     escaped=['D37']
+attribute assignment target        pinned     escaped=['D37']
+plain name carries paths           pinned     escaped=[D34 D35 D37 D38 D40 D41]
+Dict literal carries nothing       pinned     escaped=[D34 D35 D36 D42 D38 D39 D40 D41]
+source() no longer consults _paths pinned     escaped=[D34 D35 D36 D42 D37 D39 D40 D41]
+```
+
+Two survive: the `YieldFrom` step in `_pass`
+(`step = () if isinstance(node, ast.YieldFrom) else ("elem",)` — no corpus entry
+uses `yield from`, no live site depends on it) and `ast.Set` in the
+list/tuple/set literal branch of `_paths`. Both are strictly widening and both
+are five characters, so the harm is small; but § 1.5 and § 9.2 present the sweep
+as this row's own lesson applied to its own code, and the ten deleted branches
+were deleted on exactly this evidence. These two should have gone with them, or
+been planted.
+
+**Smaller survivors, same category as round 10's redundant `assertEqual(rc, 0)`:**
+
+| deletion | result |
+|---|---|
+| `assertGreater(len(sites), 60)` removed | ALL GREEN |
+| `assertGreater(len(converters), 40)` removed | ALL GREEN |
+| `with self.assertRaises(task.Refused):` → plain `try/except` | ALL GREEN |
+| `assertEqual(rc, 0, …)` neutralised | ALL GREEN (carried from round 10) |
+
+The first two are tripwires against a future degenerate census, not guards over
+today's behaviour, and I do not charge them. The third means the refusal
+assertion is a correctness check, not a coverage one — entering the function is
+what the watch needs, and `try/except` still enters it.
+
+---
+
+## Green-for-the-wrong-reason: none found
+
+Checked against the four modes this row has produced before.
+
+- **No test greps its own source.** `__file__` appears three times across
+  `test_header_index_is_the_only_fold.py` and `test_one_header_rule.py` and
+  every occurrence is a `PERRY_HOME` or `sys.path` root. There is no
+  `read_text()` over a source file in either.
+- **The condemned test is gone.** `grep -rn
+  test_the_cross_module_case_is_the_price tests/` returns nothing.
+- **No fixture parses zero rows.** `drive_the_carried_row_readers` asserts real
+  values off the parse — `board.find("TASK-001")[0] == "Work"`, `"Verification"`
+  in `ensure_columns(...)`, `"Severity"` in `ensure_section_columns(...)`,
+  `"TASK-001"` in `replace_row(...)`, `canonical_of("**Title**") == "title"` —
+  and neutralising the whole method reddens three tests.
+- **No control that cannot fail.** `C13`/`C14` proved discriminating above.
+- Both new tests are proven non-vacuous by mutation on both of their halves
+  (R11-21/22/23 for the remainder; R11-18/19 and my bogus-name plant for
+  `WATCHED`).
+- `grep -rn ROW_NAMES tests/ bin/ viewer/` returns three lines, all prose in
+  docstrings. Correct.
+
+---
+
+## What I did NOT check
+
+- **I did not reproduce all 23 mutations.** I reproduced 14 (eight code
+  mutations through my own corpus probe, R11-18/19/21/22/23 through the test
+  module, plus R10-2), chose to spend the rest of the budget on the exhaustive
+  76-site plant sweep and the independent remainder rebuild, and hunted twelve
+  further branches of my own choosing. The nine I did not run are R11-2, R11-9,
+  R11-10, R11-11, R11-13, R11-14, R11-15, R11-20 and part of R11-1 — though my
+  branch hunt covers the same code for R11-1, R11-2, R11-9, R11-10, R11-11 and
+  R11-15 with my own anchors, and all six were pinned.
+- **I did not run `test_header_rule_harness.py` as a module** (147 s). I ran
+  `measure()`, which is its subject, plus the corpus-audit invariants by
+  reading.
+- **I did not re-run `bash tests/run` on `4c2f07a`.** The 3034 figure is the
+  round 10 reviewer's and the PMO's; I verified only 3036 on this tip and the
+  +2 accounting.
+- **Criterion 2 (`perry-lint`'s `norm` IS `squash`, by identity) and criterion 5
+  (a decorated header resolves across four tools)** I did not re-derive; they
+  are carried by suites that are green on this tip.
+- **Round 8's four-CLI byte-identical differential** is carried, not
+  re-measured — § 7 limit 12 says so.
+- **The write side, localized headers and non-Python readers** are out of scope
+  per § 7 limit 9, and `viewer/parsers.py § parse_decisions` remains agreed out
+  of scope.
+- **One census-completeness question I could only bound, not close.** § 7 limit
+  3 states that `CARRIED_KEYS` undercounts a header row held under a fourth key
+  name. I swept the tree for dict values and attribute targets the static net
+  resolves as rows and found only `header`, `keys`, `end`, `cells` and `_cells`
+  — none of the last four is a *header* row read back for folding today. There
+  is a further class the census does not cover at all: a header row held in a
+  plain local from a cross-module call, never subscripted and never passed to
+  `header_index`. I found no live instance, but the census would not count one.
+
+---
+
+## Summary of what is charged and what is not
+
+**Charged (recorded, not fatal):**
+
+1. § 2.3 and `UNCOVERED`'s docstring misdescribe 3 of the 8 as cross-module.
+   `bin/perry-lint § tables` and `§ tables_with_lines` are both file-local; the
+   escape is `_paths` having no comprehension branch, and a minimal file-local
+   reproduction with the comprehension link removed is CAUGHT. Fix the sentence,
+   or close the three — the honest target for the next round is 5, not 0.
+2. The mutation table omits `D42` from five rows, so **"nine single-entry
+   mutations" is eight**. Safe direction; the same predates-the-corpus-entry
+   bookkeeping the round corrects for round 10 in § 8.
+3. Two branches of the new machinery — the `YieldFrom` step and `ast.Set` in the
+   literal branch — still survive their own deletion, corpus fully caught and
+   live census unmoved. Delete them or plant them.
+4. § 7 limit 1 attributes eleven carried sites to three files; one of the eleven
+   (`bin/perry_store.py:533 § plan`) is in the file the limit says resolves.
+   § 2.3 has it right.
+5. § 0.3's "20 under round 10's tree and workload" is loose — under round 10's
+   actual tree it is 25. § 2.2 states it correctly.
+
+**Not charged, and verified:** the remainder of 8 (twice, two instruments); the
+static verdict at all 76 sites; the dict/attribute closure and its provenance
+framing under adversarial key names; the reviewer's exact plant and its three
+named tests; the 6/11 split; the reconciliation to 20 and to the reviewer's
+twelve; `WATCHED` in both directions and the "short by eight" including
+`is_intake_register_header` already being driven; the corpus at 42/14/41 with
+0/0/0 and two controls that genuinely discriminate; fourteen mutations all red;
+R10-2 at eight; the baseline 102/3036/3 with the same three names; and the ten
+deleted branches actually being gone.
+
+**Verdict: PASS.** Round 10's rule was *measure the reach and state the
+remainder*. This round measures it, states it, asserts it in a guard that fails
+in both directions, and the number survives an independent rebuild and an
+exhaustive validation of the instrument that produced it. Eight of seventy-six,
+named by file and function, discharges the amendment.
+
+---
+---
+
+# Delta confirmation, `901d89e` → `642091f`: **CONFIRMED**
+
+> Same reviewer, same day. Scope is the delta only — the PASS above stands and
+> nothing in it is re-derived except the two numbers I was asked to re-check.
+> Everything below ran on a `git archive` export of `642091f` at
+> `scratchpad/rjr11d/` and `cp -R` copies of it; the reviewed worktree at
+> `scratchpad/review-050r11` was re-hashed against `git ls-tree -r HEAD` after
+> all of it — **722 files, 0 mismatches**, still at `901d89e`, `git status
+> --porcelain` and `git ls-files -o` both empty. Nothing was run inside it.
+> `git diff --stat 901d89e..642091f -- bin/ viewer/ schema/ templates/ packs/
+> modes/` is empty: still no production code.
+
+**All three corrections are real, and correction 3's new machinery does what it
+claims.** The four newly-found branches were genuinely unpinned before and are
+each pinned by exactly one entry now; `R11-24` reddens `D43` alone; the twenty
+greens I spot-checked are green and none is a detection branch; the anchors work.
+The remainder did not move.
+
+I found one thing worth the next round's attention, and it is the answer to
+question 3: **the sweep's stated bound does hide a class, and I can demonstrate
+it.** Dropping *one conjunct of an `and`* makes the net report a legitimate value
+normalizer — criterion 4's failure mode, the thing round 8 was failed for — with
+the entire 47-entry corpus still clean. The bound is honestly stated and no claim
+is falsified by this; it is a gap in what would be noticed if the code broke, and
+it closes with one `CLEAN` entry.
+
+---
+
+## 1. Correction 3 — the four new branches were really unpinned, and are now pinned singly
+
+`scratchpad/rjr11/rjr11_unpinned.py` neutralises each branch on **both** trees
+and runs the whole corpus (per-file planting, validated against `measure()`):
+
+```
+########## OLD 901d89e ##########  (42-entry corpus)
+  D43 branch: YieldFrom step                             escaped=[] -> UNPINNED
+  D44 branch: _rpaths_of by ATTRIBUTE name               escaped=[] -> UNPINNED
+  D45 branch: _bind_element on a comprehension generator escaped=[] -> UNPINNED
+  D46 branch: the cell() half of the tuple unpack        escaped=[] -> UNPINNED
+  D47 branch: the SUBSCRIPT half of the carried write    escaped=[] -> UNPINNED
+  ast.Set in the literal branch                          escaped=[] -> UNPINNED
+
+########## NEW 642091f ##########  (47-entry corpus)
+  D43 branch  escaped=['D43']   D44 branch  escaped=['D44']
+  D45 branch  escaped=['D45']   D46 branch  escaped=['D46']
+  D47 branch  escaped=['D47']
+  ast.Set     n/a on this tree (deleted)
+```
+
+**All five were genuinely unpinned at `901d89e`** — the corpus stayed fully
+caught with each one neutralised — and each is now a single-entry mutation. No
+`CLEAN` entry was flagged and no `SECOND_RULE` entry was caught in any run.
+`ast.Set` is gone and the reasoning for deleting rather than planting it is
+sound: a row is a list, a list is unhashable, so the branch is unreachable.
+
+**Corpus on the corrected tip: `DRIFT 47 / CLEAN 14 / SECOND_RULE 41`,
+`{escaped: [], flagged: [], second_rule_caught: []}`.**
+
+### The four mutations, run from the anchors the table now gives
+
+```
+R11-24 :420 yield-from adds an element level        ANCHOR-LINE-OK  escaped ['D43']
+R11-25 :520 a SUBSCRIPT write carries nothing       ANCHOR-LINE-OK  escaped ['D47']
+R11-26 :454 a comprehension generator binds no table ANCHOR-LINE-OK escaped ['D45']
+R11-27 :504 a tuple unpack has no cell() half       ANCHOR-LINE-OK  escaped ['D46']
+```
+
+**`R11-24` reddens `D43` and only `D43`.** Confirmed.
+
+### Do the new entries plant the live shape, or a shape built to be caught?
+
+Three of five plant a live shape; two plant a plausible shape with no live
+instance, and the round is honest about one of them and loose about the other.
+
+| entry | live? | evidence |
+|---|---|---|
+| `D44` | **yes**, minus the cross-module root | `.task_tables()` appears 6× (`bin/perry-task:811,894,918,6129`, `bin/perry_store.py:164,528`). The doc says "minus the cross-module root" — honest. |
+| `D45` | **yes** | `bin/perry_md_store.py:490` and `:549` are `{r["line"] for t in tables for r in t["rows"]}`; `bin/perry_store.py:585` likewise |
+| `D46` | **yes** | `bin/perry_store.py:858` is `i, cells = row["line"], row["cells"]` (the doc cites `:857`, off by one line; the line is there) |
+| `D47` | **no live instance** | I AST-swept every reader for a subscript assignment whose value the net resolves as a row: **0 hits**. The provenance line calls it "`D24`'s sibling", which is honest, but § 1.5's column heading is "the live shape". |
+| `D43` | **no live instance** | `grep -rn "yield from" bin/ viewer/` returns nothing |
+
+Neither `D47` nor `D43` is contrived to be caught — both are ordinary reader
+spellings of a producer pattern the file already handles, and `D43` exists
+because the alternative was carrying an unmeasured branch. But § 1.5's table
+should not present all five as live shapes when two are not. (`D37`, from the
+earlier round, is the same: **0 live attribute writes of a row**; its provenance
+is a reviewer's plant, which is a legitimate source and is what it says.)
+
+---
+
+## 2. The twenty greens — five spot-checked, all green, none a detection branch
+
+Each neutralised alone on `642091f`, judged on the author's own two-sided
+criterion (whole corpus caught **and** `test_header_index_is_the_only_fold`
+unmoved):
+
+```
+G1 L877 census ATTRIBUTE half                    GREEN  corpus clean · watch Ran 10 OK
+G2 L696 source() _source_direct short-circuit    GREEN  corpus clean · watch Ran 10 OK
+G3 L418 owner filter in the yield loop           GREEN  corpus clean · watch Ran 10 OK
+G4 L513 the `bound` continue                     GREEN  corpus clean · watch Ran 10 OK
+G5 L694 source() default-scope normalisation     GREEN  corpus clean · watch Ran 10 OK
+```
+
+That includes **both** of the ones the author says were re-verified by hand
+(L418 and the L694/L695 pair) — confirmed, the sweep and a hand check agree —
+and **both** of the "dead attribute half" ones I was asked to be suspicious of.
+
+**On the census's attribute half being dead, and why deleting it would be the
+wrong call here.** I confirmed it is dead: of the 17 live carried sites, **zero**
+are attribute reads — all are subscripts. But this is a *different* kind of dead
+from `ast.Set`. `ast.Set` is unreachable by a type argument and can never fire.
+The census's attribute half is perfectly reachable: a reader that writes
+`t.header` tomorrow would be counted, and its sibling in `_paths` (the detection
+side) **is** pinned, by `D37`. Keeping the measurement symmetric with the
+detection it measures, and stating it as a limit (§ 7.14), is the right call.
+The distinction the author draws — delete the impossible, declare the merely
+unexercised — is correct and I would not have it the other way.
+
+The other three are correctly classified too, and the reason is legible from the
+source: `_paths` calls `_source_direct` itself at `:623`, so `source()`'s
+short-circuit at `:696` is genuinely defence in depth; every caller passes
+`scope`, so `:694` never fires; and the `bound` flag's job is stopping a generic
+fall-through from marking `_` a row, which no live site and no corpus entry
+exercises.
+
+**The sweep's own control holds.** I round-tripped `tests/header_rule.py`
+through `ast.parse`/`ast.unparse` with no mutation: corpus `escaped [] flagged []
+s2 []`, `test_header_index_is_the_only_fold` `Ran 10 OK`. So the sweep's verdicts
+are attributable to the mutations and not to the round trip.
+
+---
+
+## 3. The sweep's bounds — honestly stated, AND they hide a class. Reproducible.
+
+The declared bound is *"it mutates whole `if` tests, not individual conjuncts of
+an `and`"*. That is honest and it is exactly the right thing to have written
+down. It also hides something, and the coordinator's question deserves a
+demonstration rather than an opinion.
+
+I ran the conjunct sweep the bound excludes: every operand of every `BoolOp` on
+a new-or-changed line of `tests/header_rule.py`, each replaced with the identity
+constant for its operator, AST-built and unparsed
+(`scratchpad/rjr11/rjr11_conj.py`). **36 operands: 25 green in the corpus, 10
+unneutralisable, 1 red** (`:507` `() in sub_p` → `D38`).
+
+The greens are not all equal. Most are widenings of a guard nothing exercises.
+But a specific family is load-bearing in the direction this row has already been
+failed for once — the conjuncts that make path matching **selective**:
+
+- `:659` `if p and p[0] == f"attr:{node.attr}"`
+- `:631` `isinstance(k, ast.Constant) and isinstance(k.value, str)`
+- `:502` / `:579` `q and q[0] == f"pos:{i}"`
+- `:532` `holder.id == "self" and self.class_of.get(f)`
+
+Drop the second conjunct of `:659` — one operand, nothing else — and:
+
+```
+$ sed -n '659p' tests/header_rule.py
+                if p and p[0] == f"attr:{node.attr}":
+# mutant: replace with `if p:`
+
+# a legitimate value normalizer over VALUES, on an object that also carries a row
+class T:
+    def __init__(self, line, recs):
+        self.header = split_row(line)
+        self.statuses = [r.get("status", "") for r in recs]
+def read(line, recs):
+    t = T(line, recs)
+    return [squash(s) for s in t.statuses]
+
+MUTANT (one conjunct of an `and` dropped)    -> ['bin/pr.py:9: [squash(s) for s in t.statuses]',
+                                                'bin/pr.py:9: squash(s)']
+SHIPPED                                      -> []
+
+$ corpus on the mutant:
+DRIFT escaped: []   CLEAN flagged: []   S2 caught: []
+```
+
+**The mutant reports correct code — criterion 4's failure mode, and the exact
+thing round 8 was failed for — and the entire 47-entry corpus is silent about
+it.** No `CLEAN` entry carries a decoy attribute (or a decoy key) beside a real
+row on the same object, so the selectivity of the path match is unpinned.
+
+This falsifies no claim the round makes: the bound says conjuncts are not
+mutated, and it does not say they are pinned. The shipped code is correct. It is
+a gap in what would be *noticed*, and it closes cheaply — **one `CLEAN` entry**
+in the shape of `C13`/`C14`: an object that carries a header row on one attribute
+and values on another, folded over the values; plus its dict sibling for `:631` /
+`:502` / `:579`. That single pair would pin the whole family.
+
+Recorded for the next round. It is the finding that most nearly changed my mind
+about this confirmation, and the reason it did not is that the bound was
+declared, the behaviour is right, and the fix is an entry rather than machinery.
+
+---
+
+## 4. Corrections 1 and 2
+
+**Correction 1 is in all three places**, and each says the same thing:
+
+| place | says it? |
+|---|---|
+| `tests/test_header_index_is_the_only_fold.py`, `UNCOVERED`'s comment | ✓ "FIVE are rooted in a call into ANOTHER MODULE… THREE — the `bin/perry-lint` checks — are NOT… `_paths` has no comprehension branch… the honest target for the next round is FIVE, not zero" |
+| result § 2.3 | ✓ five/three split, names `tables()` at `:194` and `tables_with_lines()` at `:209` as same-file, states the target as 5 |
+| result § 7, new limit **2** | ✓ "`_paths` has no comprehension branch, and that is a FILE-LOCAL hole" |
+
+The author reproduced my synthetic-file proof itself and says so. The
+`_bind_element`-versus-`_paths` distinction it draws in limit 2 is right and I
+verified it: `_bind_element` *is* called for a comprehension's generators (that
+is `D45`), so the residual hole is specifically `_paths` stopping at the element
+expression.
+
+**Correction 2's anchors are usable.** I replayed **five of the nine** I could
+not verify from the first draft's table, using the line anchors alone; every
+anchor line held the text the row describes, and every result matched:
+
+| # | anchor | my measurement | table |
+|---|---|---|---|
+| R11-9 | `header_rule.py:530` | `D37 D47` | D37 D47 ✓ |
+| R11-10 | `:532` | **`D37` only** | D37 only ✓ |
+| R11-11 | `:538` | `D34 D35 D37 D38 D40 D41 D46` | same ✓ |
+| R11-13 | `:639` | `D36 D38 D39` | same ✓ |
+| R11-14 | `:643` | `D38 D39` | same ✓ |
+
+and `R11-16` (`:666`) reproduces at `D35 D36 D37 D38 D39 D42 D43 D44 D45`,
+exactly the re-measured row — `D42` now included, which was my finding.
+
+**Two bookkeeping defects survive the correction, both in the same family as the
+thing correction 2 exists to fix.**
+
+1. **Three anchors are stale, and they are stale by exactly the amount
+   correction 1 added.** `R11-20 :435`, `R11-21 :126` and `R11-22 :270` are the
+   *pre-correction* line numbers. On `642091f` those lines are a comment, a
+   comment and a blank line; the real ones are `:449`, `:136`–`:143` and `:284`
+   — **+14, the lines correction 1 added to `UNCOVERED`'s comment.** All 20
+   `header_rule.py` anchors are correct, so the table was re-measured against
+   the code file and not against the test file. This is the third time on this
+   row that a table has been published against a state older than itself, and
+   this time it is the correction that fixes the previous two.
+2. **`D44` has no single-entry row in § 5.** § 1.5 says each of `D43`–`D47` "is
+   a single-entry mutation in § 5"; `D44` appears only in six multi-entry rows.
+   The claim is true in substance — I measured `_rpaths_of`'s attribute branch
+   and it reddens `D44` and only `D44` — but the row is missing.
+
+*(And § 7 now has two limits numbered **3**: the new one inserted for correction
+1 collided with the existing spelling limit, so the list runs 1, 2, 3, 3, 4 … 15
+over sixteen entries. § 7 is the list the next round is held to.)*
+
+*(§ 7 limit 1 still attributes the eleven unresolved carried sites to
+`bin/perry-task`, `bin/perry-tasks` and `bin/perry_md_store.py`; the eleventh is
+`bin/perry_store.py:533 § plan`. That was item 4 of my original charge, outside
+correction 1's scope, and it is carried.)*
+
+---
+
+## 5. Baselines and the ruling number — unmoved
+
+On a `git archive` export of `642091f`, md5s of `.perry/events.jsonl`,
+`perry/BOARD.md` and `perry/intake.jsonl` recorded first:
+
+```
+offenders_by_symbol('.')  ->  []
+
+bash tests/run
+102 modules · 3036 tests · 218.7s · 8 workers
+✗ 2 module(s) red
+```
+
+the same three failing names, unchanged:
+`test_diagnose … test_the_queue_register_reconciles_with_the_queue_on_this_repository`,
+`test_diagnose.TestUserLoadFindings.test_perry_itself_passes_its_own_id_checks`,
+`test_kr_progress_provenance … test_no_current_in_the_payload_claims_to_be_a_measurement`.
+
+**The remainder did not move.** Re-measured with my own tracer on the corrected
+tip:
+
+```
+sites 76   static-blind 27
+REMAINDER by function-entry: 8   (same eight members)
+REMAINDER by line-execution: 8   (same eight members)
+func == stated: True
+```
+
+Deleting `ast.Set` changed nothing in the census, which is what "unreachable"
+predicts. **The ruling stands: 8 of 76, measured and listed, discharges the
+amendment.**
+
+*(The write hazard reproduced a second time: all three tracked files moved after
+`bash tests/run` in the export. Disposable copy; the reviewed worktree was never
+run in.)*
+
+---
+
+## Delta verdict
+
+**CONFIRMED.** Correction 1 is in all three places and says the right thing.
+Correction 2's anchors work — five of the nine I previously could not verify now
+replay from the table alone and all five match, `D42` included. Correction 3's
+rebuilt sweep found four real, genuinely-unpinned detection branches, each now
+pinned by exactly one corpus entry planted on a shape three of which are live;
+`R11-24` reddens `D43` alone; `ast.Set` was correctly deleted rather than
+planted; the twenty greens survive spot-checking and none is a detection branch;
+and the sweep's own unparse control holds.
+
+**Carried to the next round, not blocking:** one `CLEAN` entry with a decoy
+attribute and one with a decoy key, which would close the conjunct class § 3
+demonstrates; the three stale `only_fold.py` anchors (+14); the missing `D44`
+row in § 5; the duplicated limit number 3; and § 7 limit 1's eleventh site.

+# TASK-050 — V4 review round 5: **FAIL**
+
+> Fresh-context reviewer, 2026-08-29, against `perry/evidence/2026-08/TASK-050-spec.md`.
+> Under review: `ce13c7f` on `coding/task-050-header-harness`, diffed against `45a355d`.
+> The worktree was never written to; every mutation ran on `git archive` exports.
+
+## What holds
+
+Criteria 2, 3, 4 and 5 hold. The extraction is correct — `readers_under(HEAD)`
+returns 18 files, byte-identical to the base inlined enumeration, with the
+comment skip and offender format carried over unchanged. The widening
+introduced no false positives today (old `[]`, new `[]`, newly flagged `[]`).
+Criterion 5 was exercised behaviourally across `perry-state.parse_tracks`,
+`perry-lint.norm`, `perry-diagnose.md_table` and the shared primitive: plain and
+decorated headers agree, `default_rung=V2`.
+
+The "found the fifth blind spot" claim is mechanically true. Reverting exactly
+line 139 to its `45a355d` spelling, in a fresh copy with no `__pycache__` and
+`PYTHONDONTWRITEBYTECODE=1`, fails naming exactly `bin/perry-probe-d`.
+
+## Finding 1 — the harness is a regression corpus, not a harness
+
+`CAUGHT` is six literals and `UNCAUGHT` is two. There is no generator, no
+mutation operator, no enumeration over spellings — so it cannot produce a
+finding nobody had already written down. The fifth blind spot it "found" was
+already named in prose in the same file at `45a355d`:
+`tests/test_one_header_rule.py:152`, *"A PRIVATE splitter is `.split("|")`"*.
+
+The reviewer wrote a nine-case probe and **five escaped both nets**:
+
+| case | spelling | outcome |
+|---|---|---|
+| A | `.casefold()` in a non-splitting helper taking `cells` | **escapes both** |
+| C | `.casefold()` + own splitter, in a file that already contains `squash` | **escapes both** |
+| D | `.lower()`, splitter via a `PIPE = "\|"` constant | **escapes both** |
+| E | `.lower()`, splitter via `re.split(r"\|", line)` | **escapes both** |
+| H | plain `for` loop with `.append()` instead of a comprehension | **escapes both** |
+| F | dict-comprehension header index | caught by complement only |
+| G | the rule factored into a scalar helper `_norm` | caught by complement only |
+
+Case F is **live**: `bin/perry-diagnose:1826` builds its header index as a dict
+comprehension. Case G is the natural refactor of the exact defect this row was
+opened for. Case A is the author's own `CAUGHT` entry #3 with `.lower()`
+changed to `.casefold()` — a shape the author already accepts as plausible,
+made invisible by one keyword.
+
+## Finding 2 — the "bounded" claim is false, and the test proving it is theatre
+
+`tests/test_header_rule_harness.py:173-178` argues the `.casefold()` and `map()`
+blind spots are bounded because such a reader "splits rows and would have to
+reach `squash`". That rests on `tests/test_one_header_rule.py:196`:
+
+```python
+if "squash" not in src and ".norm(" not in src:
+```
+
+A **whole-file substring test**. Every one of the 9 row-splitting readers in the
+tree already contains the token, so the complement contributes **zero** marginal
+protection against a divergent rule added to any existing reader.
+
+Demonstrated end to end, by appending to `viewer/parsers.py` — the file the
+first pass claimed to have unified, and where the fifth copy actually lived:
+
+```python
+def parse_foreign_board_header(line):
+    return [c.strip("*` ").casefold() for c in line.split("|") if c.strip()]
+```
+```
+SECOND_RULE offenders : []
+complement missing    : []
+casefold rule -> ['default** rung', 'status']
+squash   rule -> ['default rung', 'status']
+agree? False
+```
+
+That is the spec's own opening defect — `**Default** rung` → `default** rung`,
+column silently gone — planted in the historically worst file, with **both
+guards reporting nothing**.
+
+Worse, `test_the_complement_guard_would_catch_a_real_one` (lines 214-223), whose
+entire job is to prove the bound, never exercises the complement: it reads the
+sibling test file and asserts an error-message string appears in it. A grep for
+a docstring, passing regardless of whether the complement works. The structural
+reason is visible — the extraction parameterised `second_rule_offenders(root)`
+but left the complement iterating the module-level `READERS` constant pinned to
+`PERRY_HOME`. **The one net the argument depends on is the one net the harness
+cannot point at a copy.**
+
+## Finding 3 — the reported baseline was incomplete
+
+The author reported 3 modules red / 5 failures. Under `python3 -m unittest
+discover -s tests` the reviewer measured **8 failures in 4 modules**, identical
+on `45a355d` (2786 tests) and `ce13c7f` (2791 tests, +5 = the harness). The
+omitted module is `test_risks_store` (3 failures in
+`TestTheReadersAreOneFunction`).
+
+**Both numbers are true of the runner that produced them.** The author ran `bash
+tests/run`, the documented runner, under which those three pass; the TASK-095
+round 1 reviewer independently identified them as `assertIs` identity failures
+that pass in isolation and under `tests/run` — a module-double-import artifact
+of `discover` mode. Neither is caused by this change. What is fair in the
+finding is that one runner was reported without saying which, and an
+under-reported baseline is how a real regression gets absorbed. The
+runner-dependent failure is itself worth a row.
+
+## Latent risk, recorded not charged
+
+The new alternation matches any pipe-split value normalizer:
+`tags = [t.strip().lower() for t in cell.split("|")]` is flagged. No such site
+exists today, but the module's own warning about widening flagging correct call
+sites applies to this alternation the day one is written.

+         harness red naming bin/perry-probe-d. Planted 9 unforeseen spellings
+         into tempfile copies and ran BOTH nets on each: 5 escaped both.
+         Appended a casefold header reader to viewer/parsers.py — both guards
+         [] while the rules demonstrably diverge. Enumerated all 9 row-splitting
+         readers: 9/9 already contain "squash". Extraction equivalence: 18
+         readers, identical list, comment skip and offender format unchanged.
+         Widening false positives: old [] / new [] / newly-flagged [].
+         Criterion 5 exercised behaviourally across four readers.
+not-checked: did not drive perry-explain's CLI end to end (read the call site at
+         bin/perry-explain:392-394 and verified via the shared primitive); did
+         not investigate the 8 pre-existing failures' root causes, only that
+         they are identical on both trees; did not run `bash tests/run`, so its
+         template-drift guard and --help sweep were not exercised; did not audit
+         non-Python readers or packs/ modes/ decide/ goals/ — readers_under
+         scopes to bin/ and viewer/ by design and that scoping was not
+         challenged. No write-side Perry tool was run.
+proof: tests/test_one_header_rule.py:196 — `if "squash" not in src and ".norm("
+       not in src:` is a whole-file substring test that all 9 row-splitting
+       readers already satisfy, so the complement net is vacuous for any new
+       rule added to an existing reader. This falsifies the "bounded" claim at
+       tests/test_header_rule_harness.py:173-178; the test written to prove that
+       bound, at :222-223, asserts only that a string appears in a sibling
+       source file and never exercises the complement. Demonstrated: a
+       `[c.strip("*` ").casefold() for c in line.split("|")]` reader appended to
+       viewer/parsers.py reproduces the spec's own `**Default** rung` column
+       loss with both guards reporting [].

+# TASK-050 — V4 review round 7: **FAIL**
+
+> Fresh-context reviewer, 2026-08-29, against `perry/evidence/2026-08/TASK-050-spec.md`.
+> Under review: `c67e5a4`. All destructive work on `git archive` exports and
+> `tempfile` copies; the worktree ended clean at `c67e5a4`.
+
+**This is the seventh failed round.** The verdict below is why the row is now
+escalated to a user decision rather than a round 8.
+
+## What holds — and it is the first round whose numbers survive independently
+
+**The five claimed mutations reproduce exactly** — 1, 1, 1, 1, 14, each anchored
+by line, `__pycache__` cleared, `PYTHONDONTWRITEBYTECODE=1`, 1.2s past the
+second boundary, each reverted and SHA-verified.
+
+**Both baselines are accurate in both runners**, against `45a355d`:
+
+| | `bash tests/run` | `unittest discover` |
+|---|---|---|
+| `45a355d` | 91 modules · 2786 tests · 5 failures | 2786 · 8 failures |
+| `c67e5a4` | 92 modules · 2793 tests · 5 failures | 2793 · 8 failures |
+
+Identical failure sets. *"This is the first round of this row where the reported
+numbers survive independent measurement without qualification."* Round 5's
+Finding 3 is discharged.
+
+**The shared-module claim is real.** One net, root-parameterised, both callers
+pointed at planted copies. Round 5's structural defect is gone.
+
+**`readers_under` scoping holds** — the reviewer set out to break it and could
+not. 18 readers; the four skipped `bin/` files are bash; both shipped
+`templates/*/bin/*` scripts were read in full and neither parses a table header.
+
+## Finding 1 — the FAIL. Four LIVE header resolutions revert to the defect, suite green
+
+The reviewer inverted the question: not *"does the check see a file I invent?"*
+but *"of the header resolutions this tree already contains, how many can it
+see?"*
+
+| live site | what it is | guard |
+|---|---|---|
+| `viewer/parsers.py:1827` | `header = [squash(c) for c in prev_cells]` in `_table_rows` | **GREEN** |
+| `bin/perry-task:6029` | `dict(zip([norm(h) for h in ihdr], cells))` | **GREEN** |
+| `bin/perry-task:6200` | same, second site | **GREEN** |
+| `bin/perry-tasks:925` | `keys = [ops.norm(h) for h in …["header"]]` | **GREEN** |
+| `bin/perry-state:180` | scalar glossary header test | **GREEN** |
+| `viewer/parsers.py:428` | scalar — **the fifth copy** | **GREEN** |
+| `bin/perry-state:584` | `low = [squash(c) for c in cells]` | red |
+| `bin/perry-diagnose:1825` | `low = [squash(c) for c in cells]` | red |
+
+Two of eight. *"The reason is visible and it is not a shape"* — the two red ones
+iterate a variable literally named `cells`, which is in `ROW_NAMES`.
+`prev_cells` and `ihdr` are not.
+
+**`viewer/parsers.py:1827` is not hypothetical and it loses data.** Its own
+docstring says *"Header keys are `squash`ed — the one rule every Perry tool
+normalizes a header cell by."* It feeds `_parse_krs` and the `Top risks` parser
+— user-authored documents. Reverted to the historical rule:
+
+```
+pristine  _parse_krs -> [('KR-1', 'ship it')]
+mutated   _parse_krs -> []
+```
+
+The KR is silently gone — the spec's own opening defect, in a live file — and
+`bash tests/run` reports 2793 tests with the same 5 failures as the unmutated
+tree.
+
+**The measured denominator:** of **829** mapping constructs in the 18 readers,
+the check classifies **59** as a row-cell source, and **35 of those 59 are the
+single identifier `header`**.
+
+> Round 3's diagnosis was *"it matches a spelling, not a shape."* The spelling
+> has moved from a regex alternation into `ROW_NAMES`, an eleven-name
+> `frozenset`. Everything downstream of it is a genuine AST walk; the gate in
+> front of it is still an allowlist of variable names.
+
+## Finding 2 — 21 of 25 planted readers escape, and round 5's case still works
+
+Four controls planted at the identical paths were all red, so every escape is
+about the shape. Escapes include: `cells[1:]`; a dict-assignment header index; a
+`lambda` folding helper; two-level local indirection; a splitter on a class
+attribute or in a dict; an aliased row parameter (`cs = cells`);
+`sorted(key=str.lower)`; `filter`; `out.add`; `out +=`; `zip`; a walrus;
+`functools.partial`; a scalar header-row test; `str.translate`; and P23–P25,
+round 4's `_is_python` hole, carried forward untouched.
+
+**P21 is the one that matters:**
+
+```python
+def parse_foreign_header_v2(line):
+    parts = split_row(line)
+    return [c.strip("*` ").casefold() for c in parts]
+```
+
+`split_row` on its own line — *"the most ordinary spelling there is, and the one
+the tree itself uses at `bin/perry-state:579`"* — and round 5's decisive case is
+back, in the same file, against the same rule.
+
+## Finding 3 — my declared gap carries a false qualifier
+
+Both `UNCAUGHT` assertions are honest, and stating gaps as executable assertions
+is *"a real improvement over round 5"*. The reviewer failed the round on the
+**wording**: gap 2 says *"an iterable named nothing like a row **and never split
+locally**"*. P21 is split locally and escapes; so do `cs = cells`, `cells[1:]`,
+`zip(cells, values)`. That is a bound written as a description — a smaller
+instance of exactly what round 5 failed for.
+
+Worse: `test_the_cross_module_case_is_the_price_of_a_file_local_walk` asserts
+that a phrase appears in its own source file. *"That is structurally the test
+round 5 condemned … reintroduced. The commit message says the docstring-grep
+test is DELETED; a different one is present."*
+
+## Finding 4 — the check now reports CORRECT code
+
+Criterion 4's stated failure mode. Six of eight legitimate shapes flagged,
+including **FP1**, `[t.strip().lower() for t in cell.split("|")]` — verbatim the
+*"latent risk, recorded not charged"* round 5 wrote down. *"It moved from latent
+to live in the version that was supposed to answer that review."*
+
+And one character from firing on live code: adding `.lower()` to
+`bin/perry-knowledge:242`'s prose tokenizer would report a keyword extractor
+that has never seen a table as *"header cells folded by a second rule"*.
+
+> So the check is simultaneously **blind to four of this tree's own header
+> resolutions** and **loud about a keyword tokenizer**. Those are the two
+> failure modes the spec names, in one artefact.
+
+## Smaller, reported because they are results
+
+- The commit message says *"17 planted shapes … 13 flagged, 4 clean"*; the
+  shipped corpus is 14 + 4 = 18 plus the decisive-case class. The tests pass;
+  the prose does not match the file.
+- `tests/test_one_header_rule.py` imports `header_rule` twice.
+- `bin/perry-state:568` defines a file-local splitter `cells_of`;
+  `is_row_cell_source` resolves local helpers on the folding side but not the
+  source side, so a comprehension over `cells_of(s)` would escape — safe today
+  only because the result is assigned to a variable named `cells`.
+
+## Verdict
+
+```
+=== VERDICT ===
+task: TASK-050
+rung: V4
+result: FAIL
+criteria: perry/evidence/2026-08/TASK-050-spec.md
+proof: viewer/parsers.py:1827 — `header = [squash(c) for c in prev_cells]`, in
+       `_table_rows`, whose docstring calls it "the one rule every Perry tool
+       normalizes a header cell by". Reverted to `.strip("*` ").lower()` it is a
+       second header rule on live user documents, `offenders()` returns [], and
+       `bash tests/run` reports the same 5 failures as the unmutated tree.
+       Behaviourally `| **KR** id | … |` yields [('KR-1','ship it')] pristine and
+       [] mutated. The cause is tests/header_rule.py:86-88, ROW_NAMES, an
+       eleven-name allowlist not containing `prev_cells`; the same gate leaves
+       bin/perry-task:6029, :6200 and bin/perry-tasks:925 green under the
+       identical revert, and lets 21 of 25 planted readers through — including
+       `parts = split_row(line)` on one line and the comprehension on the next.
+       In the other direction the same check reports correct code:
+       `[t.strip().lower() for t in cell.split("|")]` is flagged.

+
+> The result of record for this row is
+> **`perry/evidence/2026-08/TASK-050-round9-result.md`**.
+>
+> This file is deliberately not kept alongside it as a second account. Round 8
+> FAILed its V4 review, three of its numbers were wrong, and a document that
+> states them next to a document that corrects them is two documents
+> disagreeing. What is left here is the retraction, which is the only part of
+> round 8 that is still load-bearing. The round 8 review that produced it is at
+> `perry/evidence/2026-08/TASK-050-round8-v4-review.md` and is unchanged; the
+> code it reviewed is at commit `c158418` and is in the history.
+
+## What round 8 claimed that was not true
+
+1. **"planted readers caught: 30 of 30"**, against a corpus described as *"the
+   UNION of every shape the round 5 and round 7 reviews name"* and *"a superset
+   of round 7's corpus"*. It was neither. Round 7's Finding 2 names *"a scalar
+   header-row test"* and *"P23–P25, round 4's `_is_python` hole"* among its
+   escapes; none was in the corpus, and the labels `P23`–`P25` had been re-used
+   for three different shapes, so the omission did not show in the numbering.
+   The reviewer re-derived the missing shapes, planted them with a control at
+   the same paths, and **all five escaped both nets**. The honest figure was
+   *30 of at least 33*.
+   Round 9 rebuilt the corpus from the reviews' own prose, with the source line
+   quoted for every entry and a test that refuses a re-used label.
+
+2. **"`ROW_NAMES` is no longer the gate and has not been extended."** Both
+   clauses are true and neither is the claim that matters. Emptied, the
+   harness dropped from 30 of 30 to **22 of 30**: eight catches were the
+   allowlist, not the dataflow. A second name allowlist survived at
+   `tests/header_rule.py:357-360`. Round 9 deleted both, and the shape net they
+   belonged to.
+
+3. **"`python3 -m unittest discover -s tests` disagrees with `bash tests/run`
+   by 3 on this repository."** True — but nobody had measured it, on either
+   tree, and `68e63cf` retracted it in a new § 6.9 while leaving the sentence
+   standing in § 5. Round 9 measured it on three trees. It is 3, and the three
+   are `test_risks_store.TestTheReadersAreOneFunction`.
+
+4. **"67 call sites across 10 files now reach `header_index`."** The table
+   directly beneath it summed to 58. Measured on a `git archive` export of
+   `68e63cf`: **58**. The table was right; 67 is not derivable from anything.
+
+5. **`bin/perry-diagnose § md_table` listed among the readers the closing test
+   watches.** It contributed zero recorded folds, because it pre-stripped
+   decoration before calling `header_index`. Round 9 fixed the reader and made
+   the reader list an assertion.
+
+## What round 8 got right, and round 9 kept
+
+`viewer/tables.py § header_index` and the conversion of the readers onto it.
+Round 8's reviewer verified it independently — nine mutations with md5-verified
+restores, the `parsers.py` KR proof case, `alias`-after-fold shown exact, no
+site where the `list` subclass changes behaviour, and criterion 5 driven
+end-to-end through four CLIs on a 64-cell half-bolded fixture, byte-identical.
+None of that was disturbed. Round 9's changes are two further live conversions,
+the deletion of the shape net, a rebuilt corpus and a widened runtime watch.

+item 2 — one of which the author declares, and one of which the author reports
+as met when it is not.
+
+---
+
+## What holds, measured independently
+
+**The conversion is real and the proof case is closed.** Nine mutations, each
+anchored by line number, asserted against the old text before replacing, every

+
+M9b is the round's best result and it is not in the evidence: `ihdr` is in no
+allowlist, reaches the walk only through `_, ihdr = board.section_table(…)`,
+and the returns-dataflow closes it. Round 7's Finding 1 is genuinely
+discharged.
+
+The author's line number for M1 is `1828`; the line is `1833` on the branch.
+Cosmetic.
+
+**Baselines reproduce exactly.** `bash tests/run`, on `git archive` exports of
+the committed trees (so the board state is the one committed at each SHA — I
+did **not** see the two data-dependent `test_contract_key_parity` witness
+failures the brief warned of, which is consistent with them being live-board
+artefacts):
+
+| runner | tree | modules | tests | failures |
+|---|---|---|---|---|
+| `bash tests/run` | `main` @ `6c0d041` (scratch export) | 98 | 2882 | 3 |
+| `bash tests/run` | `f1eb3f5` (this branch, worktree) | 99 | 2893 | 3 |
+
+Same three, named identically to the result: `test_diagnose` ×2
+(`test_the_queue_register_reconciles_with_the_queue_on_this_repository`,
+`test_perry_itself_passes_its_own_id_checks`), `test_kr_progress_provenance` ×1.
+The `+11` arithmetic checks out: `test_one_header_rule` 12→14,
+`test_header_rule_harness` 7→10, plus the new module's 6.
+
+**Criterion 5 holds across four CLIs and by a means the round did not use.** I
+bolded the **first word of every header cell** of every table in
+`tests/fixtures/sample-project` (64 cells — half-cell bold, where the two rules
+diverge) and ran `perry-state --json`, `perry-lint`, `perry-diagnose --json`
+and `perry-explain` on plain and decorated copies: **byte-identical except the
+echoed root path**, and identical to `main`'s output on the same inputs. (Note
+for the next round: `main` is *also* identical, so this differential has no
+discriminating power on this fixture — round 4's warning still stands.)
+
+**No guard I checked survives its own deletion.** Beyond the nine: reverting
+`read_conformance` to the historical fifth-copy rule
+(`rel.strip("` ").lower() in ("file","path")`) reddens `TestTheFifthCopy` ×2 and
+`test_every_decorated_header_cell_reached_header_index`; converting
+`_parse_intake`'s two folds to bare `[squash(c) for c in cells]` reddens
+`test_every_fold_of_a_header_cell_came_from_header_index`, which none of the
+author's own nine mutations reaches. `test_value_normalizers_are_not_flagged`'s
+`> 20` is not vacuous (the tree has 30 folding comprehensions);
+`test_the_watch_is_not_vacuous` is backed by 27 recorded folds over 9 distinct
+cells.
+
+**`test_the_cross_module_case_is_the_price_of_a_file_local_walk` is gone**, and
+nothing equivalent returned: `grep -rn "cross_module_case_is_the_price"` outside
+`evidence/` returns nothing, and none of the three new/changed test modules
+reads its own source. No `GATE_OFF` is involved (these tests reach no CLI).
+
+**`HeaderIndex` as a `list` subclass: I could not find a site where it changes
+behaviour.** No `type()`/`isinstance()` test on any converted result, no `+`,
+`+=`, `.append`, `.sort` or `.insert` on one (`bin/perry-goals:447`'s
+`header + [name]` is on raw `split_row` cells, not a `HeaderIndex`), no
+`pickle`/`deepcopy` anywhere in `bin/` or `viewer/`, and the four-CLI payload
+differential above is byte-identical to `main`. I read all ten converted files'
+diff hunks and each rewrite is semantically equal
+(`.column(*names)` on a one-element `HeaderIndex` returning `0`/`-1` reproduces
+`squash(x) in {…}`; `set(header_index(h))` reproduces `{squash(c) for c in h}`).
+
+**Claim 3 — `alias` runs after the fold, and `norm` idempotence — verified, and
+it is exact rather than approximate.** `squash` is idempotent on its own output
+(`re.sub(r"[\s`*]+"," ",s).strip().lower()` leaves no `*`, backtick or repeated
+space to collapse), and both `markdown_tables` callers pass an `alias` of the
+form `α∘squash` (`bin/perry-task § norm` is
+`_ALIASES.get(squash(s), squash(s))`; the other caller passes `squash` itself).
+So `alias(squash(c)) = alias(c)` for every cell, and the produced key list is
+byte-for-byte what `[norm(h) for h in header]` produced. The claim does not
+depend on `norm∘norm == norm`, which is the harder property and is not needed.
+
+---
+
+## Ruling on declared shortfall 1 — the false positive
+
+### (a) Is the indistinguishability claim true?
+
+**Yes as stated, and I could not break it — but it is a property of the check's
+design, not a theorem about the two programs, and the test that "asserts" it
+cannot distinguish those two things.**
+
+`_splits_on_pipe` treats *any* `.split("|")` as a row source before any
+provenance question is asked, so the receiver's name is the only remaining
+difference. I tried the obvious refinement the walk already implements
+elsewhere — giving the receiver local row provenance — and it changes nothing:
+
+```
+FP1 as shipped (no provenance)              net1=[]  net2=["rv8-fp1:3: …cell.split('|')…"]
+FP1 WITH row provenance on the receiver     net1=[]  net2=["rv8-fp1b:4: …cell.split('|')…"]
+round 5 decisive case, receiver is a LINE   net1=[]  net2=["rv8-d:3: …line.split('|')…"]
+```
+
+So the author has not stopped one step early in the way rounds 5–7 did. What
+the author *has* overstated is what
+`test_it_is_undecidable_and_that_is_asserted_not_argued` proves. It asserts
+`seen[0] == seen[1]` — that the check gives the two the same verdict. That
+assertion is satisfied by *any* check that does not read receiver names,
+including one that flags neither. It measures name-blindness, not
+undecidability. The docstring's "nothing in the two expressions differs except
+the receiver's name" is true; "so this one is left flagged" does not follow from
+it — deleting net 2 also satisfies it, and the amendment explicitly left that
+option open ("whether the walk itself survives the round is round 8's call").
+
+### (b) Does one false positive defeat option C's thesis?
+
+**Partly, and in the way that matters: it is the OLD failure mode surviving in a
+new place, because the defeated detector was kept and still gates the suite.**
+
+Net 1 — "the guard that replaces the walk", the one the amendment writes the
+requirement about — is clean on all eight legitimate shapes; I verified
+`offenders_by_symbol` returns `[]` for fp1, fp1-with-provenance and the round 5
+decisive case. On the narrowest reading of the amendment the false-positive
+requirement is met, and the author does not even claim this in his own defence.
+
+But net 2 is still shipped and `test_no_reader_folds_a_header_cell_by_a_second_rule`
+still runs it over the whole tree in `bash tests/run`. So criterion 4's named
+failure mode is live, not hypothetical. Adding a perfectly ordinary
+multi-value-cell normalizer to a **real** reader:
+
+```
+$ # appended to bin/perry-explain in scratchpad/rv8-mut (a copy):
+$ #   def owners_of(cell):
+$ #       return [t.strip().lower() for t in cell.split("|") if t.strip()]
+$ python3 -m unittest discover -s tests -p 'test_one_header_rule.py'
+FAIL: test_no_reader_folds_a_header_cell_by_a_second_rule
+AssertionError: Lists differ: ["perry-explain:797: [t.strip().lower() for t in cell.split('|') if t.strip()]"] != []
+FAIL: test_value_normalizers_are_not_flagged
+AssertionError: Lists differ: ["perry-explain:797: …"] != []
+FAILED (failures=2)
+```
+
+The suite goes red on correct code, and one of the two tests that reports it is
+literally named `test_value_normalizers_are_not_flagged`. That is criterion 4,
+verbatim, and the amendment's "the false-positive half of round 7's finding has
+to go away **as a consequence of the design**" is not satisfied by retaining it
+and writing it down.
+
+---
+
+## Ruling on declared shortfall 2 — the retraction is INCOMPLETE
+
+`68e63cf` adds § 6.9 saying no `python3 -m unittest discover -s tests` count was
+measured. It does **not** touch § 5, which still asserts as fact:
+
+> "`python3 -m unittest discover -s tests` disagrees with `bash tests/run` by 3
+> on this repository (a module-double-import artefact identified in the
+> TASK-095 round 1 review, not caused by this change)."
+
+That sentence is the retracted claim, still standing in the section the
+retraction points at. And § 6.9's own closing line — "Every number in § 5 is
+`bash tests/run`" — is not true of it: it is a number *about the other runner*,
+carried from the brief. A retraction that adds a footnote and leaves the
+sentence is the partial retraction the brief asked me to look for. Everything
+else in § 5 I measured myself and it is correct.
+
+One further carried figure, minor: § 2's prose says "67 call sites across 10
+files now reach `header_index`"; the table immediately under it sums to **58**,
+and `grep -cE "header_index\(|header_keys\("` over those ten files returns 59
+tokens (including the one inside `header_keys` itself). The 67 is not derivable
+from the round's own table.
+
+---
+
+## Finding 1 — the FAIL. "30 of 30" is measured on a corpus the round pruned, and the pruned shapes still escape
+
+The result says the corpus is "the **UNION** of every shape the round 5 and
+round 7 reviews name" and "a **superset** of round 7's corpus, so the fraction
+below is measured against a harder denominator than the amendment quotes."
+
+**It is not a superset.** Round 7's Finding 2 enumerates its escapes as:
+
+> "…`sorted(key=str.lower)`; `filter`; `out.add`; `out +=`; `zip`; a walrus;
+> `functools.partial`; **a scalar header-row test**; `str.translate`; and
+> **P23–P25, round 4's `_is_python` hole, carried forward untouched**."
+
+Two of those named classes are absent from `CAUGHT`. The round re-used the
+labels `P23`–`P25` for three *different* shapes (dict-assignment index, lambda,
+two-level indirection), which round 7 lists separately, so the omission does not
+show up in the numbering. I re-derived both from round 7's prose and planted
+them into `tempfile` copies of `bin/` + `viewer/`, running **both** nets:
+
+```
+$ python3 scratchpad/rv8work/rv8_plant.py .
+ESCAPED  R7 · a SCALAR header-row test (the `fifth copy` shape, parsers.py:428)
+ESCAPED  R7 · scalar test on a header cell, header var
+ESCAPED  R4 · python reader whose FIRST LINE is not a shebang (coding cookie)
+ESCAPED  R4 · python reader with a non-.py dotted suffix
+ESCAPED  R4 · python reader outside bin/ and viewer/ (packs/)
+CAUGHT   control · plain shape that the author's corpus catches
+           -> ['rv8-probe-control:3: [c.strip().lower() for c in cells]']
+```
+
+The control proves the planting method works at those paths. So the honest
+number against the corpus the amendment points at is **30 of at least 33**, and
+the three extra are shapes a previous reviewer had already found and written
+down. § 6.2's caveat — "a shape round 7 planted that neither review's prose
+names would not be in it" — does not cover these: round 7's prose names both.
+
+The scalar one is not a curiosity. **Neither net looks at anything but mapping
+constructs**, so a scalar fold of a header cell is outside both by
+construction — and that is the exact shape of the "fifth copy"
+(`viewer/parsers.py:428`, `read_conformance`), the copy in this row's history
+that produced a real user-visible defect. The round converted eight such scalar
+sites to `header_index([x]).column(…)`; nothing but the runtime watch's fixed
+eight-cell `HEADER_KEYS` list holds them there. A live example survives the
+round: `viewer/parsers.py:2582`, `parse_decisions` —
+`if first.lower().startswith("adr") and "id" in first.lower()` — a second
+header-row test on a header cell, invisible to both nets. Rounds 3 and 4 both
+established it is dead (`in_table` only becomes true after the separator row),
+and I confirmed that by reading the loop; I report it as the live instance of
+the class the corpus dropped, not as a behavioural bug.
+
+## Finding 2 — `ROW_NAMES` survives, is load-bearing for net 2, and a second name allowlist exists under another spelling
+
+The amendment: *"It must not need an allowlist of variable names."* The result:
+*"`ROW_NAMES` is no longer the gate and has not been extended."* Both sentences
+are true and they are not the same sentence. Measured by emptying the frozenset
+and re-running the round's own harness:
+
+```
+$ # ROW_NAMES = frozenset()
+planted readers caught : 22 of 30
+  ESCAPED: round 2 · the original spelling
+  ESCAPED: round 3 · the loop subject renamed
+  ESCAPED: round 3 · planted in a SUBDIRECTORY
+  ESCAPED: round 5 · no suffix, python by shebang only
+  ESCAPED: round 5 review · casefold in a non-splitting helper
+  ESCAPED: round 5 review · a for/append loop, no comprehension at all
+  ESCAPED: round 5 review · dict-comprehension header INDEX over enumerate()
+  ESCAPED: round 5 review · map() instead of a comprehension
+legitimate shapes flagged: 1 of 8
+```
+
+Eight of the thirty catches are the allowlist, not the dataflow. For **net 1**
+the allowlist is not load-bearing on anything I could construct — M9 and M9b
+both still fire with `ROW_NAMES` emptied — so the *symbol* check is genuinely
+name-free today; but it shares `_RowLocals.source()` with net 2 and would fall
+back to the same eleven names for a drift site with no local provenance.
+
+A second allowlist survives under another spelling, in the same function:
+`tests/header_rule.py:357-360`, `node.slice.value in ("header", "headers",
+"hdr")` — three hand-written names deciding that a subscript is a row.
+
+## Finding 3 — the test that "closes the row" does not watch one of the twelve readers it says it watches
+
+§ 4 lists `perry-diagnose.md_table` among the readers
+`tests/test_header_index_is_the_only_fold.py` runs. It records **zero** folds
+from it. `md_table` pre-strips decoration with its own rule —
+`cells = [c.strip("*` ") for c in split_row(s)]` — *before* calling
+`header_index`, so the watch's discriminator `arg.lower() != squash(arg)` never
+sees a decorated argument from it. Proven by planting the drift form inside
+`md_table` and reading the watch directly:
+
+```
+$ # bin/perry-diagnose:1825 -> low = [squash(c) for c in cells]
+stray: []
+Counter({('<listcomp>','header_index','harvest'): 8,
+         ('<listcomp>','header_index','_table_rows'): 4,
+         ('<listcomp>','header_index','_parse_cadence'): 4,
+         ('<listcomp>','header_index','_parse_intake'): 3,
+         ('<listcomp>','header_index','is_risk_register_header'): 2,
+         ('<listcomp>','header_index','_parse_user_input'): 2,
+         ('<listcomp>','header_index','parse_tracks'): 1,
+         ('<listcomp>','header_index','_parse_task_table'): 1,
+         ('<listcomp>','header_index','read_conformance'): 1,
+         ('<listcomp>','header_index','_track_context'): 1})
+```
+
+`md_table` is absent from the recorded stacks whether pristine or mutated. The
+pre-strip is behaviourally harmless (`squash` treats `*` and backtick as
+whitespace everywhere, so `squash(c.strip("*` ")) == squash(c)`), but it means
+that for a reader whose own comment says it "reads the USER's board and OKR",
+the only cover is the defeasible shape net.
+
+## Finding 4 — what the runtime net does NOT see, and it is more than dead code
+
+§ 6.4 says "a planted function nothing calls is invisible to it". True, and
+incomplete. The watch's workload never executes **`bin/perry-task`,
+`bin/perry-goals`, `bin/perry-tasks`, `bin/perry_store.py` or
+`bin/perry-migrate` at all** — 32 of the 58 converted sites in the round's own
+table — and of `bin/perry-lint`'s 6 sites only `_track_context` is reached.
+Roughly 38 of 58 converted sites are LIVE, converted, and covered by the shape
+net alone. `test_every_decorated_header_cell_reached_header_index` is narrower
+still: it fixes eight header keys and drives six entry points, so a reader that
+grows its own rule for a *ninth* column, or in a code path the six do not
+reach, stays green. That is not a reason to fail the round, but "what it cannot
+see is a reader that no parse reaches" understates it by a wide margin and
+should not stand in the evidence.
+
+## The rest of the "NOT done" list
+
+- `cells_of` not removed — **fine, and the replacement is real.**
+  `TestTheFileLocalSplitterEscapeIsClosed` plants under the name `probe`, so the
+  old accident is excluded, and `ROW_PRODUCERS` is genuinely two entries.
+- `viewer/` not renamed — out of scope (TASK-232), agreed.
+- No reader driven end-to-end from `argv` — **I did that and it passes**: four
+  CLIs, plain vs half-cell-bolded fixture, byte-identical. Discharged.
+- Three pre-existing failures not investigated — measured identical on both
+  trees by me too; acceptable.
+
+---
+
+## Verdict
+
+```
+=== VERDICT ===
+task: TASK-050
+rung: V4
+result: FAIL
+criteria: perry/evidence/2026-08/TASK-050-spec.md § Amendment 2026-08-29 (binds)
+checked: bash tests/run on git-archive exports of both trees — main @6c0d041
+         98 modules/2882 tests/3 failures, branch @f1eb3f5 99/2893/3, same
+         three named failures. Nine mutations reproduced (M1,M2,M5,M6,M7,M8,M9
+         plus two of my own), each anchored by line, asserted on the old text,
+         __pycache__ cleared, 1.2s past the second boundary, restored and
+         md5-verified; all restores verified. M9's split verdict (net 1 red,
+         net 2 green) reproduces exactly, and the ihdr drift case round 7
+         measured as escaping is now caught with no allowlist entry.
+         parsers.py:1833 revert loses the KR ([('KR-1','ship it')] ->
+         [(None,'ship it')]) and reddens 3 named tests. Criterion 5 driven
+         end-to-end through four CLIs on a 64-cell half-bolded fixture:
+         byte-identical. `norm` idempotence verified analytically and it is the
+         weaker property alias∘squash=alias that is actually needed. Corpus
+         re-derived from the round 5 and round 7 reviews and re-planted.
+         ROW_NAMES emptied and the harness re-measured. Runtime watch
+         instrumented directly. Reviewed worktree ended clean at f1eb3f5.
+not-checked: did not run `python3 -m unittest discover -s tests` on either tree,
+         so the retracted cross-runner figure is still unmeasured by anyone;
+         did not audit non-Python readers or packs/ modes/ decide/ goals/
+         beyond confirming readers_under's scope excludes them (and that a
+         Python reader planted in packs/ escapes both nets); did not
+         investigate the three pre-existing failures, only that they are
+         identical on both trees; did not exercise perry-task/perry-goals
+         through their own CLIs against a decorated board.
+proof: The round reports "planted readers caught: 30 of 30" against a corpus it
+       calls "the UNION of every shape the round 5 and round 7 reviews name"
+       and "a superset of round 7's corpus". It is not a superset. Round 7's
+       Finding 2 names "a scalar header-row test" and "P23-P25, round 4's
+       `_is_python` hole" among its escapes; neither is in
+       tests/test_header_rule_harness.py § CAUGHT, and the labels P23-P25 were
+       re-used for three different shapes so the omission is invisible in the
+       numbering. Re-derived and planted into tempfile copies of bin/+viewer/,
+       both still escape BOTH nets, as do three variants of the second:
+         ESCAPED  scalar header-row test  (cells[0].strip("*` ").lower())
+         ESCAPED  scalar test on a header cell (header[0].strip().lower())
+         ESCAPED  reader whose first line is a coding cookie, not a shebang
+         ESCAPED  reader with a non-.py dotted suffix
+         ESCAPED  reader outside bin/ and viewer/ (packs/)
+         CAUGHT   control planted at the same paths
+       The scalar class is structural: neither net inspects anything but a
+       mapping construct, so the shape of the "fifth copy" (parsers.py:428,
+       read_conformance) is outside both by construction, and a live instance
+       survives at viewer/parsers.py:2582 in parse_decisions (dead, as rounds 3
+       and 4 established). The honest fraction is 30 of at least 33.
+       The other half of amendment verification item 2 fails outright and is
+       live rather than hypothetical: appending an ordinary multi-value-cell
+       normalizer to a real reader —
+         def owners_of(cell):
+             return [t.strip().lower() for t in cell.split("|") if t.strip()]
+       — turns `bash tests/run` red with
+         FAIL: test_no_reader_folds_a_header_cell_by_a_second_rule
+         AssertionError: ["perry-explain:797: [t.strip().lower() for t in
+                          cell.split('|') if t.strip()]"] != []
+         FAIL: test_value_normalizers_are_not_flagged
+       i.e. criterion 4's named failure mode, reported by the test named for
+       it. The amendment requires that false positive to "go away as a
+       consequence of the design"; round 8 retained the defeated shape net,
+       kept it gating the suite, and declared the result instead.
+       Supporting: ROW_NAMES survives and is load-bearing for 8 of the 30
+       catches (emptied it and re-ran: 22 of 30), and a second name allowlist
+       sits at tests/header_rule.py:357-360; the retraction in 68e63cf leaves
+       the retracted sentence standing in § 5; § 2's "67 call sites" does not
+       match its own table's 58; and perry-diagnose.md_table is listed among
+       the twelve readers the closing test watches while contributing zero
+       recorded folds, because it pre-strips decoration with its own
+       `c.strip("*` ")` before calling header_index.

+
+---
+
+## 0. What changed, in one list
+
+| # | change | why |
+|---|---|---|
+| 1 | `tests/header_rule.py § offenders` — **the shape net — is deleted**, with `ROW_NAMES`, the `("header","headers","hdr")` subscript test, `_local_folders`, `FOLDING_METHODS`, `_string_constants` and `_splits_on_pipe` | it is what rounds 5–7 were failed for, and round 8 kept it gating the suite next to the check that replaces it |
+| 2 | `offenders_by_symbol` gained a **scalar half** and lost every heuristic | round 8's reviewer: the scalar class was outside both nets *by construction* |
+| 3 | two **live** sites converted, found by (2): `bin/perry-lint:339`, `bin/perry-task:1339` | the one rule was still being applied to a header cell outside `header_index` |
+| 4 | `is_python` asks the parser; `readers_under` walks the whole tree | round 4's hole, carried untouched through rounds 5, 6, 7 and 8 |
+| 5 | `tests/test_header_rule_harness.py` **rebuilt** from the round 4, 5 and 7 reviews' prose, every entry quoting its source line, no re-used labels | the pruned denominator is what failed round 8 |
+| 6 | `bin/perry-diagnose § md_table` stops pre-stripping decoration; the runtime watch drives five readers round 8 never executed; `WATCHED` is asserted | round 8's Findings 3 and 4 |
+
+---
+
+## 1. Failure 2 — the defeated shape net is DELETED
+
+Round 8 shipped two nets. The reviewer's finding, quoted:
+
+> Appending an ordinary multi-value-cell normalizer to a real reader turns
+> `bash tests/run` RED, and one of the two failing tests is named
+> `test_value_normalizers_are_not_flagged`.
+
+and, in the same review, the exit the round never took:
+
+> **Net 1 alone is clean on all eight shapes.**
+
+`offenders()` is gone. `tests/test_one_header_rule.py §
+test_no_reader_folds_a_header_cell_by_a_second_rule` is gone with it, and
+`test_value_normalizers_are_not_flagged` now asserts `offenders_by_symbol` over
+the same ~30 folding comprehensions.
+
+### Does any allowlist survive? No allowlist of variable names, anywhere.
+
+Round 8's result said *"`ROW_NAMES` is no longer the gate and has not been
+extended"*, and round 8's reviewer measured that it was still load-bearing for
+eight of thirty catches. It is now **deleted**, along with the second one the
+reviewer found at `header_rule.py:357-360`.
+
+`grep -rn "ROW_NAMES" tests/ bin/ viewer/` on the round 9 tree returns **two
+lines, all prose saying it was deleted, and no code.**
+
+> **Correction, round 10.** This said **four** lines. It is two
+> (`tests/header_rule.py:42` and `tests/test_header_rule_harness.py:48`). The
+> round 9 review measured the miscount; the load-bearing half of the sentence —
+> *no code* — was and is true. `TASK-050-round10-result.md § 4.3`. These are the name sets
+that remain, in full, so the answer can be checked rather than believed:
+
+| set | contents | what kind of name |
+|---|---|---|
+| `BLESSED` | `squash`, `norm`, `header_index`, `header_keys` | **function** names — the design |
+| `THE_RULE` | `squash`, `norm` | the one rule and its alias |
+| `ROW_PRODUCERS` | `split_row`, `header_index` | the two functions this repository is allowed to have |
+| `ITERABLE_WRAPPERS` | 9 Python builtins (`enumerate`, `zip`, …) | builtin names |
+| `NOT_A_READER` | `tests`, `.git`, `__pycache__`, `.perry` | directory names, each with a stated reason |
+| inline, in `source()` / `cell()` / `_mapping_sites` | `strip`, `lower`, `map`, `append`, … | `str`/`list` **method** names, for following a value through a chain |
+
+**No entry in any of them is a variable name**, which is what the amendment
+forbids: *"It must not need an allowlist of variable names."* A row is now what
+`split_row` or `header_index` produced, followed through local dataflow, and
+nothing else.
+
+### What the deletion loses, measured
+
+The shape net saw a reader that invents its **own** rule
+(`[c.strip("*` ").lower() for c in cells]`). The symbol net cannot: such a
+reader calls no blessed symbol. That loss is not described, it is planted:
+`SECOND_RULE` in the rebuilt harness is 41 shapes, each quoting the review that
+named it, each asserted to escape. **0 of 41 caught** (§ 3).
+
+What covers that class instead:
+
+1. **The function.** There is one `header_index`, so there is nothing for a
+   second rule to be a second copy *of*. That is the amendment's whole thesis
+   and it is not a net.
+2. **`tests/test_header_index_is_the_only_fold.py`**, which asks the
+   complementary question — *did every decorated header cell reach
+   `header_index`?* A reader that grows its own rule stops reaching it.
+   Measured: reverting `viewer/parsers.py:1833` to the historical rule reddens
+   three named tests (§ 2, R9-4), and on `main` the same revert is silent.
+3. **Criterion 3's own guard**, for the one shape the deletion is most often
+   asked about. `tests/test_row_integrity.py §
+   test_no_tool_splits_a_row_on_a_raw_pipe` reports a bare `.split("|")`
+   anywhere in `bin/` or `viewer/` — receiver-blind, so it covers both
+   `line.split("|")` and `cell.split("|")`. **Round 8's declared false positive
+   was therefore on code this repository already forbids for an unrelated
+   reason**, which is a further argument that keeping the net bought nothing.
+   `tests/test_header_rule_harness.py §
+   test_the_row_splitter_half_is_owned_by_criterion_3` asserts that lean so it
+   cannot rot.
+
+### The false-positive test now asserts what it claims
+
+Round 8's reviewer:
+
+> The test that "asserts undecidability" only asserts the two cases get the
+> SAME verdict — which any name-blind check satisfies, including one that flags
+> neither.
+
+`test_it_is_undecidable_and_that_is_asserted_not_argued` is deleted. In its
+place, `test_the_multi_value_cell_normalizer_is_not_reported_either_way`
+asserts the stronger and now-true thing: **both are silent**, each checked
+individually, because neither is a row unless `split_row` produced it. And the
+whole of `CLEAN` — 12 shapes — is asserted individually rather than one being
+excused.
+
+**Measured that the deletion is what buys it (R9-9):** putting the
+`.split("|")` row inference back — five lines — turns
+`test_each_clean_shape_is_left_alone` RED, naming `C06`. The criterion-4
+property is a consequence of the design, not a declaration.
+
+---
+
+## 2. The mutations
+
+`scratchpad/r9work/mut_r9_uniq.py`, run once, on the worktree, against
+`git status --porcelain` empty. Uniquely named and lock-guarded: two nights ago
+an agent ran two instances of its own harness against one worktree and each
+took the other's mutation as its `original`. Every mutation is **anchored by
+line number and asserted against the exact old text** before replacing; every
+``__pycache__`` cleared; 1.2 s past the whole-second boundary;
+`PYTHONDONTWRITEBYTECODE=1`; restored and **`md5`-verified against the
+pre-mutation digest**. **All ten restores verified.** Full log:
+`scratchpad/r9work/mutations-run.txt`.
+
+An earlier attempt was killed by a 10-minute tool timeout **with a mutation
+still applied**; it was found by `git status`, reverted by hand against the
+exact text (not by `git checkout`), and the harness now arms an `atexit` +
+`SIGTERM` restore before each mutation. Reported because it is the failure the
+brief names.
+
+| # | site | revert | named test(s) that went RED |
+|---|---|---|---|
+| R9-1 | `bin/perry-lint:348` `value = key` | `value = norm(key)` | `test_nothing_outside_header_index_maps_squash_across_a_row`, `test_value_normalizers_are_not_flagged` |
+| R9-2 | `bin/perry-task:1343` `zip(folded, keys)` / `== cell_key` | `zip(keys.raw, keys)` / `== squash(cell)` | same two |
+| R9-3 | `bin/perry-diagnose:1836` `header_index(raw)` | `header_index(cells)` | `test_every_reader_this_module_claims_to_watch_actually_folds_one` |
+| R9-4 | `viewer/parsers.py:1833` `header = header_index(prev_cells)` | `[c.strip("*` ").lower() for c in prev_cells]` | `test_a_bolded_kr_header_still_yields_the_KR`, `test_every_decorated_header_cell_reached_header_index`, `test_every_reader_this_module_claims_to_watch_actually_folds_one` |
+| R9-5 | `tests/header_rule.py:522` the scalar half | disabled | `test_each_drift_shape_is_caught` ×5 — `D04`, `D05`, `D09`, `D10`, `D11` |
+| R9-6 | `tests/header_rule.py:131` `is_python` | round 8's `if p.suffix: return False` | `test_each_drift_shape_is_caught` — `D21` |
+| R9-7 | `tests/header_rule.py:163` `readers_under` | round 8's `bin/` + `viewer/` walk | `test_each_drift_shape_is_caught` — `D22`; `test_the_control_is_caught_at_every_path_the_corpus_uses` |
+| R9-8 | `tests/header_rule.py:338` `by_name` lookup | round 8's `self.funcs` lookup | `test_each_drift_shape_is_caught` — `D10` |
+| R9-9 | `tests/header_rule.py:372` (add) the `.split("|")` row inference | put back | `test_each_clean_shape_is_left_alone` — `C06` |
+| R9-10 | `tests/test_header_rule_harness.py:715` label `S41` | re-used as `S01` | `test_no_label_is_re_used_for_a_different_shape` |
+
+Which entries each mutation loses was measured separately, on a `git archive`
+export at `scratchpad/r9work/mutcopy`, by running the harness's own `measure()`
+under each mutation. That is where the per-label attribution in the table comes
+from; it is not inferred from the subtest count.
+
+### The two LIVE sites the scalar half found
+
+Round 8's reviewer said the scalar class was outside both nets by construction
+and asked whether the guard is meant to cover it. **It is, it now does, and
+covering it found two live sites round 8 left converted-looking and unconverted:**
+
+- **`bin/perry-lint § canonical_column`** read `value = norm(header)`. Its one
+  caller, `_track_context:658`, already hands it `header_index`'s own output, so
+  the fold was a redundant re-application of the one rule to a header cell — one
+  edit away from `.strip("*` ").lower()` and the divergence this row exists to
+  close. Now `value = key`.
+- **`bin/perry-task § header_language`** read
+  `for cell, key in zip(keys.raw, keys)` and then `squash(cell)` — folding the
+  raw header cell a second time instead of reading the fold it had just made.
+  Now `folded = header_index(header)` and the comparison is against
+  `cell_key`. `header_index(header)[i]` **is** `squash(header[i])` by
+  construction (`viewer/tables.py:384`), so the value is identical; the glossary
+  alias is deliberately *not* applied on this side, which is why a second index
+  is built rather than `keys` reused.
+
+Neither was visible to round 8's nets: `canonical_column` folds through one
+level of indirection with no comprehension at the fold site, and
+`header_language` folds a scalar.
+
+---
+
+## 3. Failure 1 — the corpus, rebuilt with its provenance
+
+Round 8 reported *"30 of 30"* against a corpus it called *"the UNION of every
+shape the round 5 and round 7 reviews name"* and *"a superset of round 7's
+corpus"*. Its reviewer measured that it was neither, and put the honest
+denominator at **30 of at least 33**.
+
+The corpus is rebuilt **from the reviews' own prose**, not from the previous
+corpus, under three rules that are themselves asserted:
+
+1. **Every entry quotes the review line it comes from** —
+   `test_every_entry_carries_its_provenance`.
+2. **No label is ever re-used** — `test_no_label_is_re_used_for_a_different_shape`,
+   over both the full label and its key. That is the exact mechanism that hid
+   round 8's pruning (`P23`–`P25` re-used for three different shapes), and
+   R9-10 mutation-tests it.
+3. **No two entries are planted at the same path** —
+   `test_no_two_entries_are_planted_at_the_same_path`.
+
+### The three fractions, measured
+
+Run: `python3 tests/test_header_rule_harness.py` on the round 9 worktree.
+
+```
+DRIFT       caught  : 24 of 24
+CLEAN       flagged : 0 of 12
+SECOND_RULE caught  : 0 of 41 (+2 the reviews do not name)
+                      — zero is the DECLARED limit, not a failure
+```
+
+- **`DRIFT` 24 of 24** — the one rule applied to a header row, or to a cell of
+  one, outside `header_index`. This is the class the amendment writes the
+  requirement about. It includes both shapes round 8's reviewer planted and
+  found escaping (`D04`, `D05`, and the scalar test on a `header` variable is
+  `S40`'s drift twin `D11`) and all three of round 4's `_is_python` /
+  scope holes (`D20`, `D21`, `D22`).
+- **`CLEAN` 0 of 12** — up from round 8's 1 of 8, and the corpus is larger:
+  round 7's eight, plus `C06` (the same multi-value cell folded through
+  `squash` itself — the harder version, which only the row inference could get
+  wrong), plus `C10`/`C11` (scalar `squash` of a canonical name and of a value,
+  which the new scalar half must not touch), plus `C01` and `C12`.
+- **`SECOND_RULE` 0 of 41** — every shape the round 4, 5 and 7 reviews name,
+  asserted to escape, each entry naming its source. This is the cost of
+  deleting the shape net and it is stated as a number.
+
+### The denominator, and what is not in it
+
+| source | shapes planted |
+|---|---|
+| round 2 / round 3 findings | 3 |
+| round 4 verdict (incl. both `_is_python` holes) | 10 |
+| round 5 review, Finding 1 (cases A, C, D, E, F, G, H) | 7 |
+| round 5 review, Finding 2 (the decisive case) + `map()` | 2 |
+| round 7 review, Finding 2 (its full escape list, incl. P21) | 17 |
+| round 8 review, Finding 1 (the shapes it re-derived) | 2 |
+| **planted total (`SECOND_RULE`)** | **41** |
+| named in a review but **not reconstructible** | **2** |
+
+The two are round 5's probe cases `B` and `I`: its Finding 1 says *"a nine-case
+probe and five escaped both nets"* and its table names seven of the nine.
+Cases `B` and `I` appear in no sentence of that review, so there is nothing to
+derive. They are **counted in the denominator and not planted**, and
+`UNRECOVERABLE = 2` says so in the file. Inventing a shape and labelling it `B`
+is exactly the substitution that hid round 8's pruning.
+
+So: **41 planted, at least 43 named, against round 8's claimed 30 and honest
+33.**
+
+### The controls, which is what makes a zero readable
+
+`test_the_control_is_caught_at_every_path_the_corpus_uses` plants one offending
+body — the same one — at **every distinct directory the corpus uses**
+(`bin/`, `bin/lib/`, `viewer/`, `packs/`) and requires each to be caught. Round
+8's reviewer used exactly this method to expose the pruning; without it,
+"escaped" and "the scan never looked here" are the same result. R9-7
+mutation-tests it: narrowing `readers_under` back to `bin/` + `viewer/` turns
+that control red.
+
+Offender strings are now `path:line: source` with the path **relative to the
+scanned root** rather than the bare filename, because this corpus plants the
+same shape at four directories and a basename match cannot tell them apart.
+
+### Is the guard meant to cover scalar folds? Yes — and the limit is stated
+
+The **drift** half covers them: `squash(cells[0])`, `squash(row[0])`, a scalar
+fold of a loop variable, a fold through a file-local helper or a `lambda` — all
+in `DRIFT`, all caught, and R9-5 shows the code that catches them is
+load-bearing for five of the twenty-four.
+
+The **second-rule** scalar shape — `cells[0].strip("*` ").lower()`, the exact
+shape of the "fifth copy" — is `S39`/`S40` and it **escapes**, like every other
+second-rule shape. It is not a special case; it is the same declared limit.
+Round 8's reviewer named a live instance at `viewer/parsers.py:2582`
+(`parse_decisions`): rounds 3 and 4 established it is dead code, and I have not
+changed it — it is out of this row's scope and is recorded here so the next
+round does not have to rediscover it.
+
+---
+
+## 4. Failure 3 — the runtime watch stops listing readers it cannot see
+
+**Finding 3, fixed rather than removed.** `bin/perry-diagnose § md_table` was
+one of twelve readers round 8's evidence said the closing test watches, and it
+recorded **zero** folds, because it pre-stripped decoration with its own
+`c.strip("*` ")` before calling `header_index`. It now hands `header_index` the
+**raw** cells and keeps the stripped ones for the values. Same keys — `squash`
+treats `*` and a backtick as whitespace, so `squash(c.strip("*` ")) ==
+squash(c)`, which is round 8's reviewer's own observation — and the reader is
+visible: **4 recorded folds, up from 0.** R9-3 mutation-tests it.
+
+**Finding 4, narrowed.** Round 8's reviewer measured that the workload never
+executed `bin/perry-task`, `bin/perry-goals`, `bin/perry-tasks`,
+`bin/perry_store.py` or `bin/perry-migrate` *at all*. Five of those are driven
+now: `perry-task.header_language`, `perry-goals.header_language`,
+`perry_store.markdown_tables`, `perry_md_store.scan_okr` and
+`perry-migrate.fix_tables`. `bin/perry-migrate` could not be loaded at all
+before — its `@dataclass` resolves the class's own module out of `sys.modules`
+— which is why `load()` now registers before `exec_module`.
+
+**And the list is now an assertion.** `WATCHED` names 15 functions and
+`test_every_reader_this_module_claims_to_watch_actually_folds_one` requires
+every one to appear in the recorded call stacks. A reader cannot be claimed as
+watched without being watched. Measured census on the round 9 tree, by function
+(this is a measurement, not an assertion — the counts move with the fixtures):
+
+```
+8 harvest (perry-explain)      2 is_risk_register_header    1 _parse_task_table
+4 _parse_cadence               2 _table_rows                1 read_conformance
+4 md_table (perry-diagnose)    2 _parse_intake              1 _track_context (perry-lint)
+2 header_language (task+goals) 2 _parse_user_input          1 parse_tracks (perry-state)
+1 header_keys (perry-task)     1 markdown_tables            1 fix_tables (perry-migrate)
+```
+
+`bin/perry-tasks` is the one converted reader still not driven: its site needs a
+live `Board` and an `ops` module. Stated, not glossed.
+
+---
+
+## 5. Baselines — every one measured here, with its runner and its tree
+
+Nobody had measured `python3 -m unittest discover -s tests` on either tree.
+It is measured now, on both, and it settles the sentence round 8 retracted.
+
+| runner | tree | how | modules | tests | failures |
+|---|---|---|---|---|---|
+| `bash tests/run` | `main` @ `6c0d041` | `git archive` export | 98 | 2882 | 3 |
+| `bash tests/run` | round 9 (`HEAD` = `93a49a1`) | the worktree, clean | 99 | 2895 | 3 |
+| `python3 -m unittest discover -s tests` | `main` @ `6c0d041` | `git archive` export | — | 2882 | **6** |
+| `python3 -m unittest discover -s tests` | round 8 @ `68e63cf` | `git archive` export | — | 2893 | **6** |
+| `python3 -m unittest discover -s tests` | round 9 (`HEAD`) | `git archive` export | — | 2895 | **6** |
+
+Outputs: `scratchpad/r9work/run-main-6c0d041.txt`, `run-r9-worktree.txt`,
+`run-final2.txt`, `discover-main.txt`, `discover-branch-68e63cf.txt`,
+`discover-r9.txt`.
+
+`bash tests/run` was run **twice** on this branch's code: once at
+`5e737ed` (`run-r9-worktree.txt`) and once on the committed tip
+(`run-final2.txt`), because the first run was before the evidence files
+existed and `test_diagnose` reads this repository. The second run is why
+the minted task id in § 6.5 was caught and removed. Both report
+99 / 2895 / 3, the same three names. The `discover` row for round 9 is a
+`git archive` export of `5e737ed`; the code is byte-identical at the tip,
+which changes only `perry/evidence/`.
+
+**The two runners differ by exactly 3, on every tree, and the three are named.**
+`bash tests/run` reports:
+
+- `test_diagnose.DecisionsAreCountedPerRecordNotPerMention.test_the_queue_register_reconciles_with_the_queue_on_this_repository`
+- `test_diagnose.TestUserLoadFindings.test_perry_itself_passes_its_own_id_checks`
+- `test_kr_progress_provenance.TestBothOfTodaysWrongReadingsFlip.test_no_current_in_the_payload_claims_to_be_a_measurement`
+
+`discover` reports those three plus
+`test_risks_store.TestTheReadersAreOneFunction` × 3
+(`test_the_bullet_and_placeholder_rules_are_one_object`,
+`test_the_columns_are_one_list`,
+`test_the_register_header_predicate_is_one_object`).
+
+Round 8's § 5 asserted this disagreement and round 8's reviewer failed the round
+because it was carried, not measured, and because `68e63cf`'s § 6.9 retracted it
+in a footnote while leaving the sentence standing. **It is now measured, on
+three trees, and it is true**; the module is `test_risks_store`, which is the
+same module round 5's reviewer independently identified as a `discover`
+double-import artefact. Not caused by this change: identical on `main`.
+
+**The +13.** 2895 − 2882 = 13 over `main`, and it reconciles exactly against
+round 8's +11: `tests/test_header_index_is_the_only_fold.py` 6 → 7 (the census
+test), `tests/test_header_rule_harness.py` 10 → 12, and
+`tests/test_one_header_rule.py` 14 → 13 (the deleted shape-net test).
+11 + 1 + 2 − 1 = 13.
+
+**The three failures are pre-existing and identical on both trees** — measured,
+not assumed, on the two `bash tests/run` rows above. The two `test_diagnose`
+failures are board-state-dependent; both trees here carry the same committed
+board, which is why they appear on `main` too.
+
+### Call sites — the number round 8 got wrong
+
+Round 8's § 2 prose said *"67 call sites across 10 files"* while its own table
+summed to 58. **Measured on `git archive` exports of both trees**, counting
+`header_index(` and `header_keys(` outside `def`/`import`/comment lines:
+
+| tree | total | of which |
+|---|---|---|
+| round 8 @ `68e63cf` | **58** | `perry-task` 23, `parsers.py` 16, `perry-lint` 6, `perry-goals` 5, `perry_store.py` 2, `perry-state` 2, `perry-tasks`/`perry-migrate`/`perry-explain`/`perry-diagnose` 1 each |
+| round 9 (`HEAD`) | **59** | the same, plus `header_language`'s new `header_index(header)` in `perry-task` |
+
+So round 8's **table was right and its prose was wrong**; 67 is not derivable
+from anything. One of the 58 is `header_keys`'s own call to `header_index`, so
+57 are call sites in readers and one is the wrapper's hop.
+
+`readers_under` returns **20** files on the round 9 tree (18 under round 8's
+`bin/`+`viewer/` scope, plus `templates/knowledge-base/bin/kb-lint` and
+`templates/ops/bin/deliverable-lint`).
+
+---
+
+## 6. What was NOT done, and what is not proven
+
+Stated plainly, because eight rounds of this row were reported as more complete
+than they were.
+
+1. **The static net cannot see a second RULE, and that is now 0 of 41
+   measured**, not a sentence. If the next reviewer's position is that a static
+   category check is required by criterion 1, this round does not provide one
+   and says so — the amendment replaced that requirement with a symbol check
+   and this is the symbol check.
+2. **The runtime watch only sees code a parse reaches.** Five more readers are
+   driven than in round 8 and the reader list is asserted, but a fold in a
+   branch these fixtures do not take, or for a **ninth** column beyond the eight
+   in `HEADER_KEYS`, is still invisible. `bin/perry-tasks` is converted and not
+   driven.
+
+   > **Closed in round 10.** This limit is the one the round 9 reviewer walked
+   > through: it planted its escape into `bin/perry-tasks` *because* this
+   > sentence named it. `cmd_intake_write` is now driven in process and
+   > `cmd_intake_write` is asserted in `WATCHED`.
+
+   > **And this list was incomplete.** The review found a tenth limit in none
+   > of these nine — the static net recognising the rule by name rather than by
+   > symbol. § 7 of the round 10 result re-states the limits from scratch for
+   > that reason.
+3. **Round 5's probe cases `B` and `I` are unrecoverable** and are counted, not
+   invented. § 3.
+4. **`viewer/parsers.py:2582` (`parse_decisions`) is untouched** — a live
+   instance of the scalar second-rule class, established as dead code by rounds
+   3 and 4. Not in scope; recorded so it is not rediscovered.
+5. **`bin/perry-state § cells_of` was not removed** and `viewer/` was not
+   renamed — the spec's own closing note says do this row first and the
+   rename afterwards, and it is a separate row. Unchanged from round 8.
+   (Round 8's review cites a task id for the rename; it is not on this
+   branch's board, so it is deliberately not repeated here — writing it
+   into a state file is how a dangling reference gets minted, and doing
+   so grew `test_perry_itself_passes_its_own_id_checks`'s pre-existing
+   failure by one element until this was removed.)
+6. **The three pre-existing failures were not investigated**, only measured as
+   identical on both trees under both runners.
+7. **No reader was driven end-to-end from `argv` in this round.** Round 8's
+   reviewer did that himself across four CLIs on a 64-cell half-bolded fixture
+   and found it byte-identical; that result is **carried from the round 8
+   review**, not re-measured here. `bash tests/run`'s `--help` sweep, template
+   drift guard and the two sample-project lints did run, on the round 9 tree.
+8. **The mutation harness's own "TREE AFTER" line printed `DIRTY`.** That is
+   the harness's lockfile, which it deletes after the check — a bug in the
+   scratch tool, not a tree state. `git status --porcelain` on the worktree
+   immediately afterwards was empty, and all ten `md5` restores verified.
+9. **`squash`'s docstring still says "do not map this across a header row"**,
+   which after this round is half the rule; the scalar half is not mentioned
+   there. A one-line docs edit, not made, so that this round's diff stays what
+   it says it is.

+# TASK-050 — V4 review round 9: **FAIL**
+
+> Fresh-context reviewer, 2026-08-30, against
+> `perry/evidence/2026-08/TASK-050-spec.md § Amendment 2026-08-29 — USER-904,
+> option C`, which binds.
+> Under review: `b5e7be3`, tip of `coding/task-050-header-index`, in the
+> read-only worktree at `scratchpad/review-050r9`. **Every plant, mutation and
+> suite run below happened on `git archive` exports and `cp -R` copies under
+> `scratchpad/v4r9-rj/`**, never on the reviewed tree. No write-side Perry tool
+> was run. No identifier was minted. The reviewed worktree was verified
+> byte-identical to its commit at the start and again at the end.
+
+**This is the ninth failed round, and it does not fail for round 8's reasons.**
+All three of round 8's findings are genuinely closed: the corpus is rebuilt with
+auditable provenance and I could not find a shape it pruned; the shape net is
+gone; the retraction is now the whole document rather than a footnote. The
+conversion is real, all ten of the round's mutations reproduce, and I could not
+find a converted site the tree cannot see.
+
+It fails because **deleting the shape net puts the entire static claim on the
+drift half, and the drift half is not stated over the symbol — it is stated over
+the symbol's spelling.** A one-line rebinding of `squash` to any name other than
+`norm` maps the one rule across a header row, outside `header_index`, with every
+guard this row ships reporting nothing.
+
+---
+
+## THE RULING THIS REVIEW EXISTS FOR: 0 of 41 on `SECOND_RULE` is ACCEPTABLE
+
+I rule for the author on this, and the argument is not "the amendment lets him
+off" — it is that the amendment *chose* this trade with its eyes open and round
+9 is the first round to price it honestly.
+
+1. **The amendment names the alternative and rejects it.** "Option A, widening
+   the source-expression recognition for an eighth round" is explicitly
+   rejected; "four rounds have now moved the defect this way." Catching a
+   reader that writes `[c.strip("*` ").lower() for c in cells]` *is* source-
+   expression recognition — there is no other way to see a fold that calls
+   nothing. A reviewer who fails the round for 0 of 41 is ordering option A.
+2. **The amendment defines the guard as a one-symbol check** — "no call to
+   `squash` on a row cell exists outside `header_index()`. State it over the
+   symbol, not over a shape." A symbol check is blind to a shape by
+   construction. 0 of 41 is the arithmetic of that sentence, not a shortfall
+   against it.
+3. **The two halves are the same trade, and I measured that they are.** The
+   amendment requires the criterion-4 false positive to "go away **as a
+   consequence of the design**, not by adding exceptions." Mutation R9-9
+   reproduces exactly: putting the `.split("|")` row inference back turns
+   `test_each_clean_shape_is_left_alone` RED on `C06`, quoting
+   `["bin/perry-probe-c06:4: [squash(t) for t in cell.split('|')]"] != []`. The
+   inference that would let the net see more second rules is precisely the
+   inference that reports correct code. You cannot have 41 of 41 and 0 of 12.
+4. **The row's own subject is not left uncovered — it is covered dynamically.**
+   The title is "one normalization, not two", and a reader that *writes* a
+   second one stops reaching `header_index`. That is caught:
+   `test_every_decorated_header_cell_reached_header_index` goes RED under R9-4
+   (reverting `viewer/parsers.py:1833` to the historical rule) and it went RED
+   under my own probe that replaced the same site with a *value-identical*
+   alias fold, naming `['due', 'kr']`. So the second-rule class is seen at
+   runtime for the readers the workload drives; it is the static net that is
+   blind, and the static net is not what the amendment asked to close the row.
+5. **Round 8's supporting argument for the deletion holds, and I verified its
+   reach rather than taking it.** `tests/test_row_integrity.py §
+   test_no_tool_splits_a_row_on_a_raw_pipe` really is receiver-blind and really
+   does cover the whole of `bin/` and `viewer/`: `SPLIT_RE =
+   re.compile(r"\.split\((['\"])\|\1\)")`, `_tools()` is `rglob("*")` over both
+   directories with `EXEMPT = {"viewer/tables.py"}` and no other exclusion.
+   Appending round 8's exact declared false positive to a copy:
+
+   ```
+   $ # appended to bin/perry-explain in scratchpad/v4r9-rj/fp-probe (a copy):
+   $ #   def owners_of(cell):
+   $ #       return [t.strip().lower() for t in cell.split("|") if t.strip()]
+   $ python3 -m unittest discover -s tests -p 'test_row_integrity.py'
+   FAIL: test_no_tool_splits_a_row_on_a_raw_pipe
+   AssertionError: Lists differ: ['bin/perry-explain:796'] != []
+   Ran 33 tests in 1.102s
+   FAILED (failures=1)
+   ```
+
+   Round 8's false positive was on code the repository already forbids for an
+   unrelated reason. Keeping the shape net for it bought nothing.
+
+**So 0 of 41 is a stated limit and the row does not fail on it.** But accepting
+it has a corollary, and the corollary is the finding: with the shape net gone,
+the *whole* static claim of this row is the drift half. It must therefore
+actually be what it says it is.
+
+---
+
+## Finding — the FAIL. `offenders_by_symbol` is defeated by a one-line alias, and the corpus plants the two harder indirections but not the easy one
+
+### The escape
+
+`BLESSED` / `THE_RULE` recognise the rule by the names `squash` and `norm`.
+`_RowLocals` resolves a fold reached through a `def` wrapper and through a
+name-bound `lambda` — the two indirections earlier reviews named — but nothing
+resolves a plain rebinding. Planted into copies of the round 9 tree
+(`scratchpad/v4r9-rj/rj_probe2.py`, one plant at a time, control included):
+
+```
+$ python3 scratchpad/v4r9-rj/rj_probe2.py scratchpad/v4r9-rj/tree-r9
+CAUGHT  A  fold = lambda s: squash(s)   (== corpus D10)
+ESCAPED B  fold = squash               (ONE character simpler)
+ESCAPED C  fold = squash, SCALAR on a cell
+CAUGHT  D  def fold(s): return squash(s)  (== corpus D09)
+ESCAPED E  from tables import squash as fold
+ESCAPED F  import tables; fold = tables.squash
+ESCAPED G  the repo's OWN idiom, renamed: `keyof = squash` in a real reader shape
+```
+
+Each escaped body is `[fold(c) for c in split_row(line)]` — the one rule, the
+same function object, mapped across a row's cells, outside `header_index`. That
+is `DRIFT` by the corpus's own definition, not `SECOND_RULE`: it invents no
+rule and it is not covered by the declared 0-of-41 limit. The corpus reports
+**24 of 24**, and it contains D09 and D10 — the two *harder* spellings — and
+not B/E/F/G.
+
+**This is not an exotic spelling: it is the repository's own idiom.**
+`bin/perry-lint:250` is literally `norm = squash`. `norm` happens to be in
+`BLESSED`, so that one site is seen; the same line written with any other name
+is not. Round 4's review already mutated that exact line, so the idiom is on
+this row's record.
+
+**And the round did think about import aliasing.** Corpus entry `D06` is
+`from tables import squash as norm` — aliasing that happens to land on a name
+already in `BLESSED`, and it is caught. The case where the alias lands anywhere
+else is the one that is neither planted nor handled. The check is not
+alias-blind by oversight of the whole category; it is alias-blind exactly where
+being alias-blind matters.
+
+Two further escapes fall out of the same per-function scoping and are worth
+recording rather than charging: a fold inside a nested `def` closing over the
+enclosing function's row variable escapes (`RJ10`), and so does the scalar form
+of the alias (`C` above). Everything else I planted — a class method, a
+subdirectory two levels deep, a module-level constant row, `tables.squash(c)`
+through the module object, a row from `self.section_table(...)`, and a
+`{squash(c): v for c, v in zip(cells, vals)}` dict comprehension — is **caught**.
+The drift half is strong. It is not what its own docstring calls it.
+
+### The live demonstration: a converted reader, unguarded by both legs
+
+The round states (§ 4, § 6.2) that `bin/perry-tasks` is "the one converted
+reader still not driven" by the runtime watch. That makes it the file where the
+static hole is not backstopped. Planted into `scratchpad/v4r9-rj/tasks-alias`,
+a full copy:
+
+```python
+# bin/perry-tasks:80-81
+ from tables import header_index, squash  # noqa: E402
+ _fold = squash
+
+# bin/perry-tasks:926-928  (was: keys = header_index(...["header"], alias=ops.norm))
+     _hdr = perry_store.intake_table(board, ops)["header"]
+     keys = [ops.norm(_fold(c)) for c in _hdr]
+```
+
+```
+$ python3 -c "import sys; sys.path.insert(0,'tests');
+              from header_rule import offenders_by_symbol; print(offenders_by_symbol('.'))"
+offenders_by_symbol: []
+
+$ python3 -m unittest discover -s tests -p 'test_header_index_is_the_only_fold.py'
+Ran 7 tests in 4.287s
+OK
+$ python3 -m unittest discover -s tests -p 'test_one_header_rule.py'
+Ran 13 tests in 6.029s
+OK
+$ python3 -m unittest discover -s tests -p 'test_row_integrity.py'
+Ran 33 tests in 2.849s
+OK
+```
+
+And the whole suite, on that same planted copy:
+
+```
+$ bash tests/run
+99 modules · 2895 tests · 183.9s · 8 workers
+✗ 2 module(s) red
+```
+
+— the **same three pre-existing failures and no others**
+(`test_diagnose` ×2, `test_kr_progress_provenance` ×1), byte-for-byte the set
+the unplanted tree reports. Nothing in this repository notices.
+
+The amendment's sentence is *"no call to `squash` on a row cell exists outside
+`header_index()`."* Here such a call exists, on a live converted reader, and the
+check reports nothing about it. By the round's own standard this is the defect
+it says it closed: its justification for converting `bin/perry-lint:339` and
+`bin/perry-task:1339` is that a redundant re-application of the one rule to a
+header cell is *"one edit away from `.strip(\"*` \").lower()` and the divergence
+this row exists to close."* A guard that cannot see such a site written as
+`fold = squash` cannot hold the surface it just shrank.
+
+### Why this fails the round rather than being recorded
+
+Rounds 3 through 7 were failed for a check that recognises a **spelling**: a
+regex alternation, then `ROW_NAMES`, then the `("header","headers","hdr")`
+subscript test. Round 9 deleted every allowlist of variable names — I verified
+that, it is real, and it is the best work this row has produced. What survives
+is recognition of the rule by the **function's name**, and the escape is one
+line long, uses an idiom already in the tree, is absent from a corpus that
+plants both harder cousins, and is not among the nine limits § 6 declares. That
+is the same failure mode in a new place, which is exactly the standard the
+previous eight rounds were held to.
+
+It is also small to fix: resolve module-level `NAME = <blessed>` and
+`from tables import squash as NAME` bindings into the blessed set (`_RowLocals`
+already does the analogous thing for `f = lambda`), then add B/E/F to `DRIFT`
+with their provenance.
+
+---
+
+## What holds, measured independently
+
+**The tree matches its commit exactly.** The brief flagged the hand-restored
+mutation as the one place this could have gone wrong silently. I recomputed the
+git blob SHA of every tracked file in the worktree against `git ls-tree -r
+HEAD`: **688 files checked, 0 mismatches**, `git status --porcelain` empty,
+`git ls-files -o --exclude-standard` empty. The hand restore left no residue.
+
+**No allowlist of variable names survives, under any spelling.** Checked every
+name set in `tests/header_rule.py`, not only the ones the result's table lists:
+
+| set | contents | kind |
+|---|---|---|
+| `BLESSED` | `squash`, `norm`, `header_index`, `header_keys` | function names |
+| `THE_RULE` | `squash`, `norm` | function names |
+| `ROW_PRODUCERS` | `split_row`, `header_index` | function names |
+| `ITERABLE_WRAPPERS` | 9 builtins | builtin names |
+| `NOT_A_READER` | `tests`, `.git`, `__pycache__`, `.perry` | directories, each with a reason |
+| `source()` | `strip`, `copy` | `str`/`list` methods |
+| `cell()` | `strip`, `lstrip`, `rstrip`, `lower`, `casefold`, `upper`, `replace`, `title` | `str` methods |
+| `offenders_by_symbol` (b) | `append`, `add`, `update`, `insert`, `setdefault` | container methods |
+| `_mapping_sites` | `map`, `filter`, `sorted`, `min`, `max` | builtin names |
+
+None is a variable name. `ROW_NAMES` and the `("header","headers","hdr")`
+subscript test are gone from code. (Minor: the result says
+`grep -rn "ROW_NAMES" tests/ bin/ viewer/` returns **four** prose lines; it
+returns **two**. The load-bearing half — no code — is true.)
+
+**`header_index` is the only thing that folds a header cell — checked by a means
+the author did not use.** Rather than the AST net or the runtime watch, I
+enumerated *every* call to `squash`/`norm` under `readers_under(.)` with my own
+AST walk (`scratchpad/v4r9-rj/rj_allcalls.py`) — **39 sites in 7 files** — and
+classified each by reading its enclosing function. Every one is a value
+normalizer (`squash(was)`, `squash(outcome or "")`, `squash(cell or "")` on a
+*track* cell), a canonical column name (`norm("ID")`, `norm(c)` for `c` in a
+`needed` list, `squash(LEGACY_DUE_COLUMN)`), a glossary spelling
+(`squash(spelling)`, `squash(name)`), a `##`-heading test
+(`squash(line[3:])`, `squash(head)`), or a slug (`squash(label)`). **None is a
+header cell.** My grep-based first pass missed `bin/perry-migrate:647
+L.norm('By when')`; the AST pass caught it and it is a constant. So no third
+live site exists — subject to the alias caveat above, which is about what could
+be written, not about what is there.
+
+**Both live conversions are real and semantically equal.**
+`bin/perry-lint § canonical_column`: its only caller is `_track_context:667`,
+`canonical_header = [canonical_column(cell) for cell in header]` where
+`header = header_index(split_row(line))` — the input is already folded, and
+`norm = squash` (line 250, `assertIs`-guarded) is idempotent on its own output,
+so `value = key` is exact. `bin/perry-task § header_language`:
+`folded = header_index(header)` replaces round 8's `zip(keys.raw, keys)` +
+`squash(cell)`, and `header_index(h)[i] == squash(h[i])` by construction
+(`viewer/tables.py:384`), so the comparison is unchanged. The round 9 code diff
+over `68e63cf` is exactly three files and nothing else.
+
+**All ten mutations reproduced, on `cp -R` copies, each anchored by line and
+asserted against the exact old text before replacing.** All ten anchor lines
+contain what the result says they contain, and each reddens exactly the named
+test(s) — no more and no fewer.
+
+| # | site | result |
+|---|---|---|
+| R9-1 | `bin/perry-lint:348` `value = key` → `norm(key)` | `test_nothing_outside_header_index_maps_squash_across_a_row` + `test_value_normalizers_are_not_flagged` RED (and `test_the_static_net_is_the_one_that_sees_dead_code`) |
+| R9-2 | `bin/perry-task:1343/1346` back to `keys.raw` + `squash(cell_key)` | same two RED, plus `test_every_fold_of_a_header_cell_came_from_header_index` |
+| R9-3 | `bin/perry-diagnose:1836` `header_index(raw)` → `(cells)` | `test_every_reader_this_module_claims_to_watch_actually_folds_one` RED, subtest `[md_table]` |
+| R9-4 | `viewer/parsers.py:1833` → the historical rule | exactly the three named tests RED, incl. `test_a_bolded_kr_header_still_yields_the_KR` |
+| R9-5 | `tests/header_rule.py:522` scalar half disabled | `test_each_drift_shape_is_caught` ×5 — `D04`, `D05`, `D09`, `D10`, `D11`, exactly as claimed |
+| R9-7 | `readers_under` narrowed to `bin/`+`viewer/` | `D22` **and** `test_the_control_is_caught_at_every_path_the_corpus_uses [packs/…]` RED |
+| R9-9 | the `.split("|")` row inference put back | `test_each_clean_shape_is_left_alone` RED naming **`C06`** — criterion 4 is a consequence of the design, confirmed |
+| R9-6 | `is_python` back to round 8's `if p.suffix: return False` | `test_each_drift_shape_is_caught` — **`D21` only** |
+| R9-8 | `by_name` lookup back to round 8's `self.funcs` lookup | `test_each_drift_shape_is_caught` — `D10` |
+| R9-10 | label `S41` re-used as `S01` | `test_no_label_is_re_used_for_a_different_shape` RED on the label KEY |
+
+R9-6 reddening `D21` **and not `D20`** is itself the evidence for the D20 note
+below: under round 8's `is_python`, a suffix-less file with a shebang is still
+seen, and `D20` is planted with one.
+
+**The corpus: rebuilt independently from the round 4, 5 and 7 reviews, and I
+found no pruning.** I read all three reviews and enumerated the shapes each
+names, then mapped them onto the corpus:
+
+- round 5 Finding 1's nine-case probe names seven — A/C/D/E/H/F/G → `S15`–`S21`.
+  **Cases `B` and `I` genuinely appear in no sentence of that review**; I looked.
+  `UNRECOVERABLE = 2` is honest and the refusal to invent them is right.
+- round 5 Finding 2 → `S23` (the decisive case) and `S22` (`map()`).
+- round 5's "latent risk, recorded not charged" → `C05`, and `C06` is its harder
+  twin.
+- round 7 Finding 2's escape list — `cells[1:]`, dict-assignment index, lambda,
+  two-level indirection, class attribute, in a dict, aliased row parameter,
+  `sorted(key=str.lower)`, `filter`, `out.add`, `out +=`, `zip`, walrus,
+  `functools.partial`, scalar header-row test, `str.translate`, and P21 — all
+  seventeen are present as `S24`–`S39`, `S41`.
+- round 4's nine green plants and both `_is_python` holes → `S04`–`S14`,
+  `D20`–`D22`.
+- Round 4's shapes 1 (two levels deep) and 2 (class method) are named but not
+  planted; both were RED at the time. I planted the drift form of each myself
+  and both are **CAUGHT** (`bin/lib/parse/rjprobe5.py`, `viewer/rjprobe4.py`),
+  so nothing hides there.
+
+My per-source attribution differs from the result's table by one or two entries
+(I make it 3 + 11 + 7 + 2 + 17 + 1; the table says 3 + 10 + 7 + 2 + 17 + 2). The
+total, 41, and the "at least 43" are right. The three auditability tests are
+live: blanking one `source` reddens `test_every_entry_carries_its_provenance`;
+pointing `S02` at `S01`'s path reddens
+`test_no_two_entries_are_planted_at_the_same_path`; truncating `SECOND_RULE` to
+20 reddens `test_the_denominator_is_at_least_round_8s_honest_one`.
+
+**Baselines reproduce exactly, on `git archive` exports, runner and tree named.**
+
+| runner | tree | modules | tests | failures |
+|---|---|---|---|---|
+| `bash tests/run` | `main` @ `6c0d041` (export at `v4r9-rj/tree-main`) | 98 | 2882 | 3 |
+| `bash tests/run` | round 9 `HEAD` = `b5e7be3` (export at `v4r9-rj/tree-r9b`) | 99 | 2895 | 3 |
+| `python3 -m unittest discover -s tests` | `main` @ `6c0d041` | — | 2882 | **6** |
+| `python3 -m unittest discover -s tests` | round 9 `HEAD` | — | 2895 | **6** |
+
+The three `bash tests/run` failures are identical on both trees and are the
+three the result names:
+`test_diagnose.DecisionsAreCountedPerRecordNotPerMention.test_the_queue_register_reconciles_with_the_queue_on_this_repository`,
+`test_diagnose.TestUserLoadFindings.test_perry_itself_passes_its_own_id_checks`,
+`test_kr_progress_provenance.TestBothOfTodaysWrongReadingsFlip.test_no_current_in_the_payload_claims_to_be_a_measurement`.
+I did not see the two `test_contract_key_parity` witness failures the brief
+warned of, which is consistent with them being live-board artefacts — these are
+committed-state exports.
+
+**The retracted § 5 sentence is measured and it is true.** Nobody had run
+`discover` on either tree before round 9; I ran it on both, serially, on the
+same exports. It is 2882 / 6 on `main` and 2895 / 6 on round 9 — **exactly 3
+more than `bash tests/run` on each tree**, and the three extra are exactly the
+three the result names:
+
+```
+FAIL: test_risks_store.TestTheReadersAreOneFunction.test_the_bullet_and_placeholder_rules_are_one_object
+FAIL: test_risks_store.TestTheReadersAreOneFunction.test_the_columns_are_one_list
+FAIL: test_risks_store.TestTheReadersAreOneFunction.test_the_register_header_predicate_is_one_object
+```
+
+identical on both trees, so not caused by this change. I corroborated round 5's
+diagnosis independently: `python3 -m unittest discover -s tests -p
+'test_risks*.py'` on the round 9 tree is `Ran 134 tests … OK`, so the three
+failures are a `discover`-mode double-import artefact and nothing else. The
+`+13` also reconciles: 2895 − 2882 = 13, and the round's accounting of it
+(`test_header_index_is_the_only_fold` 6→7, `test_header_rule_harness` 10→12,
+`test_one_header_rule` 14→13, over round 8's +11) is arithmetically right.
+
+**Call sites — the number round 8 got wrong is settled, and the result's figures
+are exact.** Counted by AST (`ast.Call` whose callee is `header_index` or
+`header_keys`) over `git archive` exports, excluding `tests/`:
+
+```
+68e63cf : 58   perry-task 23, parsers.py 16, perry-lint 6, perry-goals 5,
+               perry-state 2, perry_store.py 2, perry-diagnose/-explain/
+               -migrate/-tasks 1 each
+b5e7be3 : 59   the same, +1 in perry-task (header_language's header_index)
+```
+
+The per-file breakdown matches the result's table cell for cell. 67 is not
+derivable from anything. `readers_under` returns **20** files; the four `bin/`
+files it skips (`perry-codex-preflight`, `perry-detect-host`,
+`perry-dispatch-limit`, `perry-update-check`) are `#!/usr/bin/env bash`, and
+`viewer/` holds only `parsers.py` and `tables.py`. The scope claim holds.
+
+**The undecidability test is genuinely replaced.**
+`test_it_is_undecidable_and_that_is_asserted_not_argued` is gone;
+`test_the_multi_value_cell_normalizer_is_not_reported_either_way` asserts
+`_hits(...) == []` for `cell.split("|")` and for `line.split("|")` **in separate
+`subTest`s**, which is the stronger property round 8's reviewer asked for, not
+"same verdict".
+
+**Round 8's retraction is now complete.** `TASK-050-round8-result.md` is
+replaced in its entirety by a retraction note listing all five wrong claims and
+pointing at round 9. There is no surviving sentence asserting the retracted
+`discover` figure.
+
+**No new test is green in a way I could show to be vacuous.** The runtime watch
+fixtures parse real rows (`_table_rows(OKR)` → 2 rows, `parse_top_risks` → 1,
+`_parse_user_input` → 1); `test_the_watch_is_not_vacuous` asserts >5 folds and
+>3 distinct decorated arguments; none of the three modules greps its own source;
+none reaches a CLI, so `tests/gate.py`'s `GATE_OFF` is not involved;
+`test_value_normalizers_are_not_flagged`'s `> 20` floor is backed by the tree's
+~30 folding comprehensions.
+
+---
+
+## Smaller results, reported because they are results
+
+- **Corpus entry `D20` does not plant what it is labelled.** `_plant` writes
+  `SHEBANG + body` unconditionally, so `D20 "no suffix and NO SHEBANG"` — and
+  `S12`, same label — are planted **with** `#!/usr/bin/env python3`. The entry
+  cannot discriminate the round 4 hole it names, and R9-6's own attribution
+  (only `D21` goes red) shows it. The property itself is fine: I planted a
+  drift reader at `bin/perry-rjprobe2` with no suffix and no shebang, and one
+  at `bin/perry-rjprobe3` whose first line is `# -*- coding: utf-8 -*-`
+  (round 4's shape 6e), and **both are CAUGHT**. So this is a corpus-accuracy
+  defect, not a guard defect — but it is a mislabelled entry in the file whose
+  whole point this round is that its labels are trustworthy.
+- **A guard that survives its own deletion.** `Watch.__enter__`'s module
+  rebinding loop carries the comment *"Rebind every one of them, or the patch
+  watches nothing and the test is vacuous — which `test_the_watch_is_not_vacuous`
+  is here to catch."* I replaced `for attr in ("squash", "norm"):` with
+  `for attr in ():` and **all 7 tests in the module stayed green**, including
+  `test_the_watch_is_not_vacuous`. The loop is dead weight today (every fold
+  reaches the patched `tables.squash` through `header_index`), and the comment
+  claims a protection that does not exist.
+- **`test_the_row_splitter_half_is_owned_by_criterion_3` asserts half its
+  docstring.** It checks that `SPLIT_RE` matches both spellings; it does not
+  assert *"and its scan covers `bin/` and `viewer/`"*, which is the half the
+  lean actually depends on. I verified that half by planting instead.
+- **`test_value_normalizers_are_not_flagged` and
+  `test_nothing_outside_header_index_maps_squash_across_a_row` now end in the
+  same assertion** (`offenders_by_symbol(PERRY_HOME) == []`). The first plants
+  nothing; its distinct content is the `folding > 20` floor. That is why R9-1
+  and R9-2 redden both. Not wrong, but the pair reads as two checks and is
+  one and a half.
+- **`test_each_second_rule_shape_escapes` asserts blindness**, so an
+  improvement to the net turns it red. Its failure message gives the migration
+  instruction, which is the right way to do it; noted so the next round is not
+  surprised.
+- `viewer/parsers.py:2582 § parse_decisions` is still a live instance of the
+  scalar second-rule class and still dead code, as rounds 3, 4 and 8 all found.
+  Agreed out of scope; recorded so round 10 does not rediscover it.

+         consequence of the design. Corpus rebuilt independently from the round
+         4, 5 and 7 reviews and mapped entry by entry — no pruning found; round
+         5's cases B and I confirmed unnameable in that review's prose. Round
+         4's two named-but-unplanted shapes (class method, two-level
+         subdirectory) planted by me: both CAUGHT. All squash/norm call sites
+         under readers_under enumerated by my own AST walk (39 sites, 7 files)
+         and classified by reading: none folds a header cell. Call sites
+         re-counted by AST: 58 on 68e63cf, 59 on b5e7be3, per-file table exact.
+         readers_under = 20; the four skipped bin/ files confirmed bash.
+         test_row_integrity's reach verified by planting round 8's exact
+         declared false positive into a copy of bin/perry-explain: RED, so the
+         author's argument for the deletion holds. Round 8's retraction is now
+         the whole document. Every plant and every run on copies under
+         scratchpad/v4r9-rj; no write-side Perry tool; no identifier minted.
+not-checked: did not drive any reader end-to-end from argv —
+         round 8's four-CLI byte-identical differential is carried, not
+         re-measured; did not investigate the three pre-existing failures,
+         only that they are identical on both trees under bash tests/run; did
+         not audit the write side, localized headers, or non-Python readers
+         beyond confirming readers_under's scope; did not run the full suite
+         on any tree carrying live board state.
+proof: With the shape net deleted, the drift half carries the whole static
+       claim, and it recognises the one rule by the FUNCTION'S NAME rather than
+       by the symbol. A one-line rebinding walks past. Planted one at a time
+       into copies of the round 9 tree, control included
+       (scratchpad/v4r9-rj/rj_probe2.py), every body being
+       `[fold(c) for c in split_row(line)]`:
+         CAUGHT  fold = lambda s: squash(s)      (== corpus D10)
+         CAUGHT  def fold(s): return squash(s)   (== corpus D09)
+         ESCAPED fold = squash
+         ESCAPED from tables import squash as fold
+         ESCAPED import tables; fold = tables.squash
+       The corpus plants both HARDER indirections and neither easy one, and
+       reports DRIFT as 24 of 24. `norm = squash` at bin/perry-lint:250 is the
+       repository's own idiom for this line; it is seen only because `norm`
+       happens to be in BLESSED.
+       Demonstrated on a live converted reader that the round itself states the
+       runtime watch does not drive (§ 4, § 6.2), in a full copy at
+       scratchpad/v4r9-rj/tasks-alias — bin/perry-tasks, `_fold = squash` at
+       :81 and `keys = [ops.norm(_fold(c)) for c in _hdr]` at :928, replacing
+       `header_index(...)`:
+         offenders_by_symbol('.')                                  -> []
+         test_header_index_is_the_only_fold.py    Ran 7 tests   OK
+         test_one_header_rule.py                  Ran 13 tests  OK
+         test_row_integrity.py                    Ran 33 tests  OK
+       and `bash tests/run` on that same planted copy: 99 modules / 2895 tests
+       / the SAME three pre-existing failures and no others (183.9s, 8
+       workers) — byte-for-byte the failure set of the unplanted tree.
+       That is the one rule mapped across a header row, outside header_index,
+       on a converted reader, with every guard this row ships reporting
+       nothing — the amendment's sentence, "no call to `squash` on a row cell
+       exists outside `header_index()`", falsified by one line. It is DRIFT and
+       not SECOND_RULE, so the declared 0-of-41 limit does not cover it, and it
+       is in none of the nine limits § 6 declares.
+       RULING ON THE QUESTION THE ROUND TURNS ON: 0 of 41 on SECOND_RULE is
+       ACCEPTABLE under option C and is NOT why this fails. The amendment
+       rejects option A by name, defines the guard as a one-symbol check, and
+       requires criterion 4's false positive to go away as a consequence of the
+       design — and R9-9 shows the row inference that would raise 0 of 41 is
+       the same inference that reports C06, so 41 of 41 and 0 of 12 cannot both
+       be had. The second-rule class is covered dynamically instead, and that
+       cover is live: reverting parsers.py:1833 reddens
+       test_every_decorated_header_cell_reached_header_index, as does a
+       value-identical alias fold at the same site. The round fails on the
+       corollary of accepting that: the half that is left must be over the
+       symbol, and it is over the spelling.
+       Supporting: corpus entry D20 ("no suffix and NO SHEBANG") is planted
+       WITH a shebang, because _plant writes SHEBANG + body unconditionally, so
+       it cannot discriminate the hole it names (the property nonetheless
+       holds — I planted the real shape and it is caught); Watch.__enter__'s
+       module-rebinding loop can be emptied with all 7 tests still green,
+       contradicting its own comment that test_the_watch_is_not_vacuous catches
+       that; test_the_row_splitter_half_is_owned_by_criterion_3 asserts the
+       regex but not the scan coverage its docstring leans on; and
+       `grep -rn "ROW_NAMES" tests/ bin/ viewer/` returns two prose lines, not
+       the four the result claims (no code, which is the half that matters).
+       The fix is small: resolve module-level `NAME = <blessed>` and
+       `import squash as NAME` bindings into BLESSED — _RowLocals already does
+       the analogous thing for `f = lambda` — and add the three escapes to
+       DRIFT with their provenance.

+## Amendment 2026-08-29 — USER-904, option C. This section binds.
+
+Seven rounds failed V4. Each round's fix moved the same defect rather than
+closing it: round 5's reviewer defeated a regex, round 6 replaced it with an AST
+walk, round 7 showed the walk's gate is still an allowlist of variable names
+(`ROW_NAMES`, 11 entries). The user answered USER-904 with **option C**. Where
+this amendment and the original disagree, this wins.
+
+### The deliverable is a SMALLER SURFACE, not a better detector
+
+**One `header_index()` becomes the only function allowed to fold a header cell**,
+and the guard becomes *"nothing outside it calls `squash` on a row cell"* — a
+one-symbol check instead of a shape to recognise. This is the move ADR-007
+already made for stores: the way you stop two implementations drifting apart is
+to have one.
+
+**Explicitly rejected:**
+
+- **Option A**, widening the source-expression recognition for an eighth round.
+  Four rounds have now moved the defect this way.
+- **Option B**, inverting the burden so ~30 legitimate value normalizers carry an
+  opt-out marker. It was the fallback and it was not chosen.
+- **Option D**, accepting the guard as advisory. The row does not close at a
+  lower rung.
+
+### What round 8 must convert
+
+Every header resolution in the 18 readers routes through `header_index()`,
+including the sites round 7 measured as escaping:
+
+- `viewer/parsers.py:1827` (`prev_cells`) — reverting this one **silently drops a
+  KR**, with the whole suite green.
+- `bin/perry-task:6029` and `bin/perry-task:6200`
+- `bin/perry-tasks:925` (`ihdr`)
+- `bin/perry-diagnose:1826`, a **dict comprehension** — a shape
+  `tests/test_one_header_rule.py`'s `SECOND_RULE` cannot see at all.
+- `bin/perry-state:568` defines a file-local row splitter `cells_of`;
+  `is_row_cell_source` resolves local helpers on the folding side but not the
+  source side, so a comprehension over `cells_of(s)` escapes today and is safe
+  only because the result happens to be named `cells`.
+
+### The guard that replaces the walk
+
+After conversion the check is: **no call to `squash` on a row cell exists outside
+`header_index()`.** State it over the symbol, not over a shape. It must not need
+an allowlist of variable names, and it must not fire on a value normalizer — the
+false-positive half of round 7's finding (6 of 8 legitimate planted shapes
+flagged, including the exact latent risk round 5 recorded) has to go away as a
+consequence of the design, not by adding exceptions.
+
+### The AST harness is scaffolding, not the deliverable
+
+`tests/header_rule.py` and `tests/test_header_rule_harness.py` are on `main` as
+of `28f231b`, merged deliberately and with their limits recorded in that merge
+commit. Use the 25-case planting harness to VERIFY the conversion — a planted
+reader that folds outside `header_index()` must be caught, and every one of the
+8 legitimate shapes must be silent. Whether the walk itself survives the round is
+round 8's call; it is not what closes the row.
+
+Also delete `test_the_cross_module_case_is_the_price_of_a_file_local_walk`, which
+greps its own source for a phrase in its own docstring — structurally the test
+round 5 condemned, reintroduced while the commit message claimed it was deleted.
+
+### Verification — V4, amended
+
+The original's "How to check it" still holds, plus:
+
+1. Each of the six named sites above is converted, and each conversion is
+   **mutation-tested**: the exact revert reddens a NAMED test. Anchor by line,
+   assert on the old text before replacing, clear `__pycache__`, wait past the
+   whole-second boundary, restore with an `md5` check.
+2. The 25-case planting harness: all 25 planted readers caught, zero of the 8
+   legitimate shapes flagged. Round 7 was 4 of 25 caught and 6 of 8 falsely
+   flagged; anything short of the full result is a partial answer and must be
+   reported as one.
+3. `parsers.py:1827` specifically: show that reverting it now reddens a test,
+   since today it silently drops a KR with 2882 tests green.
+4. Baselines name both the runner and the tree. `main` at 70eae67 is 98 modules
+   / 2882 tests / 3 failures under `bash tests/run`.
+
+### Note for whoever schedules this
+
+`viewer/` is due a rename — the web console it is named for was deleted under
+TASK-178 and 51 files still reference the directory, 33 of them via
+`sys.path.insert`. That rename touches `viewer/tables.py` and the same 18
+readers this row converts. Do this row FIRST; the rename is mechanical and
+conflict-free afterwards.

+# TASK-095 — V4 review round 1: **FAIL**
+
+> Fresh-context reviewer, 2026-08-29, against `perry/evidence/2026-08/TASK-095-spec.md`.
+> Under review: commit `38f000f`, merged as `5cac6b5`.
+> All work done on copies in a scratch directory; the live tree was read-only.
+
+## What passed, and passed well
+
+**Criterion 1 — the grep.** At the reviewed commit `grep -n "parse_tracks(" bin/*`
+returns two lines (definition `bin/perry-state:561`, one call `:781`) against
+five at the parent `b288399` — the definition plus the four call sites the spec
+names, at the lines it names. The reviewer also grepped by expression rather
+than by name (`^##\s+(?:Tracks|轨道)`, and every `.perry/config.md` read in
+`bin/`) and found no fifth site hidden behind a different name.
+
+**Criterion 2 — the payload does not move.** Stronger than asked:
+`project.config.tracks[]` is byte-identical including key order (1671
+characters both sides), the whole of `project.config` is identical, and
+`generated_at` is the only differing key in the entire payload.
+
+**Criterion 3 — mutation.** Run on all four sites rather than one, each
+line-anchored, each with `__pycache__` cleared, a 2-second wait past the second
+boundary and `PYTHONDONTWRITEBYTECODE=1`. All four RED. Confirmed at scale by a
+revert control: the clean checkout of `5cac6b5` has 8 failures, and the same
+checkout with all four sites reverted has 12 — the same 8 plus exactly these 4.
+
+**Criterion 4 — the suite.** Red at the reviewed commit under either runner, and
+the reviewer proved it is not this change's doing: with the change entirely
+backed out at the merge commit, all 8 failures persist unchanged.
+
+## Finding 1 — the FAIL
+
+**`declared_tracks` falls back to the markdown in three states where the store
+exists**, and those are exactly the states the KR counts.
+
+`stored_tracks` returns `None` on four conditions. Only one — no store on disk —
+is the adoption/migration path the KR excludes. The other three occur **with
+`.perry/config.jsonl` present**:
+
+- any exception during load or validate (`bin/perry-state:750-751`)
+- any validation finding (`:752-753`)
+- a store carrying no `kind: track` record (`:756-757`)
+
+`bin/perry-state:781` then reads `.perry/config.md` as truth. That is the KR's
+counted condition at a call site neither named exclusion covers.
+
+**Demonstrated, not argued.** On a fixture whose `.perry/config.jsonl` holds two
+valid track records (`main`, `intake`) plus one truncated trailing line — the
+shape an interrupted write leaves:
+
+```
+perry-lint : ⚠ .perry/config.jsonl [config-store-unreadable] … not readable as JSONL
+perry-state --json → project.config.tracks[] : [('main', 'project')]
+             (the store on disk holds main AND intake)
+```
+
+`intake` disappears from all four converted call sites at once. `perry-task
+--track intake` refuses a track the project really declares, `perry-goals`
+reports it undeclared, `perry-diagnose` scans one track, and **the payload
+carries no signal at all** — it looks like an ordinary single-track project. Two
+further states reach the same line: an empty store, and a valid store with no
+`kind: track` record beside a `## Tracks` table that has rows.
+
+The docstring at `:733-737` names these cases and defends them by pointing at
+`perry-config verify` and `perry-lint`. That mitigation is real — `perry-lint`
+does warn in all three — but it is a different command, and it does not change
+what the four call sites read, which is what the KR counts and what the spec's
+Deliverable asserts in as many words.
+
+**Narrowest correct fix, per the reviewer**: distinguish *no store* from *store
+present but unusable* inside `declared_tracks`. The first is the excluded
+adoption path; the second is the counted condition.
+
+## Finding 6 — every fallback branch is untested
+
+Three mutations inside the new code came back **GREEN** against
+`test_work_modes`, `test_md_store`, `test_store_drift` and `test_parsers`:
+
+- `:752` `if findings:` → `if False:`
+- `:751` `return None` → `raise`
+- `:757` `return None` → `return []`
+
+No test calls `stored_tracks` or `declared_tracks` directly; the new class
+exercises only the healthy-store and no-store paths. The three branches that
+produce finding 1 have no coverage in either direction.
+
+## Findings 2–5 — real, and filed separately rather than folded in
+
+2. **`parse_config` still gates the store behind the markdown's existence.**
+   `bin/perry-state:120-121` early-returns when `.perry/config.md` is absent, so
+   a project with a populated store and no markdown has **no `tracks` key at
+   all**. `perry-goals:2112` and `perry-task:6690` were updated to
+   `jsonl exists OR md exists`; `perry-state` was not. Predates this commit.
+3. **The config store's other seven records are still read from the markdown** —
+   6 settings at `bin/perry-state:120-135`, `Conformance gate` at
+   `bin/perry-conform:304`. Under the KR's literal wording those are the same
+   category. The commit calls them "a separate row"; the reviewer could not find
+   that row.
+4. **The risks reader** — `viewer/parsers.py:3899-3900` builds `top_risks` from
+   `BOARD.md` while `perry/risks.jsonl` exists, reached from
+   `bin/perry-state:1631`. The task and OKR readers beside it already prefer
+   their stores.
+5. **`perry-config diff` reports `identical: true` on a store missing every
+   track record**, while `perry-lint` correctly reports six drifted rows. A hole
+   in the drift-comparison reader the KR excludes by name — but the spec cites
+   that command's `identical: true` as evidence the store and file agree.
+
+## Verdict

+```
+=== VERDICT ===
+task: TASK-095
+rung: V4
+result: FAIL
+criteria: perry/evidence/2026-08/TASK-095-spec.md
+checked: all work on copies, live tree read-only. Criterion 1: grep by name AND
+         by expression, 2 lines vs 5 at parent. Criterion 2: parent-bin vs
+         reviewed-bin over identical data, project.config byte-identical, only
+         generated_at differs. Criterion 3: four line-anchored mutations, each
+         RED, __pycache__ cleared + 2s wait + PYTHONDONTWRITEBYTECODE=1;
+         full-suite revert control 12 vs 8. Two more RED (:705, :762), three
+         GREEN (:751, :752, :757). Criterion 4: 2786 tests / 8 failures at clean
+         5cac6b5; all 8 persist with the change backed out. Finding 1 reproduced
+         on three fixtures.
+not-checked: the Chinese config path (轨道) through declared_tracks; multi-repo
+         layouts where the state root is not the project root; whether the 8
+         pre-existing failures are real defects or stale expectations;
+         perry-migrate/perry-tasks internals beyond confirming no parse_tracks
+         call; viewer/ beyond load_snapshot's sources; perry-diagnose's execute
+         stage (out of scope, high-stakes); Windows paths; any project other
+         than Perry's own fixtures.
+proof: bin/perry-state:750-757 — stored_tracks returns None on an exception, on
+       any validation finding, and on a store with no track record, all three
+       with .perry/config.jsonl PRESENT; bin/perry-state:781 then reads
+       .perry/config.md as truth. A store holding valid main and intake records
+       plus one truncated line makes project.config.tracks[] report only main,
+       with no signal in the payload — the KR's counted condition, at a call
+       site neither named exclusion covers, and untested (three green mutations
+       at :751, :752, :757).

+# TASK-095 — V4 review round 2: **FAIL**
+
+> Fresh-context reviewer, 2026-08-29, against `perry/evidence/2026-08/TASK-095-spec.md`.
+> Under review: `3d2ef25`. All destructive work on copies; the reviewed
+> worktree ends byte-identical.
+
+## The short version, in the reviewer's words
+
+> Round 2 correctly identifies that `stored_tracks` was collapsing four
+> situations into one `None`, and correctly splits them. Then it makes the same
+> mistake one level down.
+
+## Criteria — all four re-measured, not assumed
+
+**Criterion 1 PASS.** Two lines at `3d2ef25` (`perry-state:566` def, `:827` the
+adoption path). Swept by expression as well as by name; no fifth site.
+
+**Criterion 2 PASS**, and `tracks_source` is judged an acceptable addition:
+`project.config.tracks[]` is byte-identical, 1671 characters both sides, and the
+criterion is scoped by its own words to that array. `test_contract_invariance`
+forbids removals and retypes, not additions.
+
+**Criterion 3 PASS.** Four line-anchored call-site mutations, all RED, plus six
+branch mutations.
+
+**Criterion 4** red and provably not this change's doing: 93 modules / 2811
+tests / 3 red at `3d2ef25` against 92 / 2795 / 3 red with `bin/` restored — the
+identical five failures.
+
+## Finding 1 — the FAIL. `no-track-record` is a VALID state, and it is now a hard write-block
+
+`schema/state-schema.json` line 5, `work_modes.note` (DESIGN-003, **locked**
+2026-08-16):
+
+> "Absent a Tracks section there is one implicit track named `main`, mode
+> `project` — which is today's Perry exactly, so nothing here changes an
+> existing project until it opts in."
+
+and the `^Tracks\b` entry: *"OPTIONAL: skipped entirely when the section is
+absent, which is what keeps every pre-DESIGN-003 project valid."*
+
+Round 2 put `no-track-record` into `TRACKS_STORE_UNUSABLE` and hung a permanent
+write refusal off it. Reproduced on a config with no `## Tracks` section, whose
+store was built by Perry's own supported command:
+
+```
+$ perry-config write --from-file      → wrote .perry/config.jsonl (4 records)
+$ perry-config verify                 → drift_count 0, byte_identical true
+$ perry-config diff                   → identical true
+$ perry-lint                          → config store: 4 record(s), 0 drifted
+
+# 2b01253 (before round 2):
+$ perry-task add …    → wrote TASK-001 (add) → store + journal + BOARD.md + event
+# 3d2ef25 (round 2):
+$ perry-task add …    → refused — … carries no `kind: track` record … Repair the
+                        store — `perry-lint` and `perry-config diff` name the
+                        disagreement …
+```
+
+Three things wrong at once, per the reviewer:
+
+1. **The store is not broken**, so the refusal message is factually false on the
+   project it fires on — there is no disagreement for those two commands to name,
+   and both report none.
+2. **The only working remedy it offers is "delete the store"** — the opposite of
+   what P003-O2 exists to achieve.
+3. **There is no way out through the front door**: `perry-config write
+   --from-file` re-derives the same trackless store forever.
+
+**Reach: three of this repo's six `config.md` files** have no `## Tracks`
+section — `tests/fixtures/sample-project`, `sample-project-zh`,
+`witness-project`. The refusal fires *before* the conformance gate, so it also
+masks the refusal the user would otherwise have seen.
+
+*"Round 1 failed this row for collapsing four situations into one answer;
+`:803` collapses two."* An empty store and a settings-only store both land on
+`no-track-record`; the first is broken, the second is correct output of a
+correct command.
+
+**The narrowest correct fix, per the reviewer**: `no-track-record` should
+neither fall back to the markdown nor refuse. A store that validates and
+declares zero tracks **has answered**, and DESIGN-003 already specifies the
+answer: `[dict(DEFAULT_TRACK)]`, `source = store`. That removes the last
+markdown read the KR counts on that branch *and* removes the refusal. Only
+`unreadable` and `invalid` genuinely mean "a store is sitting there and cannot
+be used".
+
+The warning cries wolf on the same branch, which is exactly the failure mode the
+commit message says it avoided for `absent` — it picked the wrong branch to
+exempt.
+
+## Finding 2 — `perry-goals`' refusal has no test at all
+
+`bin/perry-goals:2123` → `if False:` is **GREEN against all 2811 tests**. The
+eight-line guard the commit message calls out as half of the deliberate
+asymmetry can be deleted without a single test noticing:
+`tests/test_track_register_source.py` never invokes `perry-goals`. The message's
+claim that it covers *"both callers"* is true only if `perry-goals` is not one —
+and the same message names it as one, twice.
+
+**This is round 1's finding 6 verbatim, inside round 2's own fix.**
+
+Every other new branch mutated came back red: refusing on `absent` (RED),
+dropping the read-only condition (RED), warning on `absent` (RED), the warning
+never firing (RED), `tracks_source` never entering the payload (RED), the
+fallback mislabelling itself as `store` (RED).
+
+## Finding 3 — the commit record misreports a mutation
+
+Round 1's third mutation in its **faithful** form — `return [],
+TRACKS_STORE_NO_TRACK_RECORD` — is green at module and full-suite level. The
+commit message reports it RED; that is true only of the variant that *also*
+relabels the source as `store`. The consequence: `declared_tracks`' documented
+invariant *"never empty"* is unguarded — nothing in 2811 tests asserts it.
+
+## Finding 4 — two of the four call sites are still silent
+
+The stated principle (*a read may degrade with a warning; a write may not
+degrade at all; what a read may never do is stay silent*) is applied to
+`perry-state` and to neither of these:
+
+- **`perry-diagnose:1894`** still calls the plain `declared_tracks`. Measured on
+  the torn-store fixture: `work_modes.tracks: ['main']` while the store declares
+  `main` AND `intake`, `register_declared: True`, no `tracks_source`, empty
+  stderr. *"This is round 1's finding 1 unchanged, at the fourth converted call
+  site."* The commit message enumerates "THE THREE CALLERS" and never mentions
+  the fourth — a spec whose Baseline names four.
+- **`perry-task list`** takes the projection silently, and a row's `mode` blanks:
+  `('TASK-001','intake','queue')` → `('TASK-001','intake','')`, empty stderr.
+  `schema/task-list-contract.md` documents `""` as *"the payload does not
+  know"* — it does not know, and it does not say so.
+
+Recorded as real gaps but not the FAIL: they leave round 1's defect where it
+was. Finding 1 is the FAIL because round 2 **created** it.
+
+## Finding 5 — the KR cannot honestly read 0
+
+`P003-O2-KR1` counts *"call sites in `bin/` that read a projected markdown file
+as truth while its store exists"*. `bin/perry-state:126-135` reads six
+`kind: setting` values from `.perry/config.md` while the store holds all seven;
+`bin/perry-conform:304` reads `Conformance gate` the same way. Neither is an
+excluded reader. **The literal count after this row is at least 7, not 0.** The
+honest number is *"0 track-register readings"*, which is what this row was
+scoped to deliver.
+
+## Finding 6 — a claimed filing, on the branch, that is not there
+
+The commit message states findings 2–5 were *"filed to `## Intake`"*.
+`git show --stat 3d2ef25` touches four files, none of them `perry/BOARD.md`.
+**The rows were filed — in the PMO tree, on `main`, not on the branch the
+message describes.** Second round running that a filing claim did not match the
+commit under review; round 1's finding 3 was *"the commit calls them 'a separate
+row'; the reviewer could not find that row."*
+
+## What round 2 got right, in the reviewer's words
+
+> The `(rows, source)` signature is the right shape and the right narrowing of
+> round 1's fix. Splitting `declared_tracks_detail` from `declared_tracks` gives
+> callers a real choice without breaking the plain readers. `TRACKS_STORE_WHY`
+> as one wording for three callers is the correct answer to "N implementations
+> of one rule". … The refusal genuinely writes nothing, verified by whole-tree
+> hash. … Six of seven mutations I aimed at the new code came back red. The
+> failure is one branch classified into the wrong bucket, and one guard nobody
+> tested.
+
+The refusal was also verified stronger than its own test asserts: SHA-1 of every
+file in the tree, before and after two refused writes on each of three states —
+**TREE UNCHANGED** in all cases. The shipped assertion checks one file under a
+comment saying "nothing".
+
+## Verdict
+
+```
+=== VERDICT ===
+task: TASK-095
+rung: V4
+result: FAIL
+criteria: perry/evidence/2026-08/TASK-095-spec.md

+# TASK-095 — V4 review round 3: **FAIL**
+
+> Fresh-context reviewer, 2026-08-29, against `perry/evidence/2026-08/TASK-095-spec.md`.
+> Under review: `515eff4`. All destructive work on copies; the reviewed
+> worktree ends git-clean.
+
+> **The short version, in the reviewer's words:** *"Round 2 correctly identifies
+> that `stored_tracks` was collapsing four situations into one `None`, and
+> correctly splits them. Then it makes the same mistake one level down."* —
+> and round 3 makes it one level below that.
+
+## All four criteria PASS
+
+**C1** — 2 lines at `515eff4`; swept by expression (all 16 `.perry/config.md`
+references in `bin/`, the sole `^##\s+(?:Tracks|轨道)` matcher); no fifth site.
+**C2** — `project.config.tracks[]` byte-identical, 2181 chars; the only
+`project.config` delta is `+tracks_source`. **C3** — all four call-site
+mutations RED (3/2/2/2). **C4** — both runners at **both** commits: `tests/run`
+5 failures each side, `discover` 2786/8 vs 2839/8, sorted `FAIL:` lines diffing
+to **identical sets**.
+
+## The ten states, enumerated
+
+The reviewer called `stored_tracks` directly on constructed fixtures and judged
+each classification, write path and payload. Eight of ten are right. Two are not:
+
+| # | store | md `## Tracks` | `source` | tracks | write | verdict |
+|---|---|---|---|---|---|---|
+| 2 | 0 bytes | — | `invalid` | md | **refused** | **wrong — Finding 2** |
+| 6 | settings only | **none** | `store` | `[main]` | allowed | **right — the round 2 fix works** |
+| 7 | settings only | **declares two** | `store` | `[main]` | allowed | **wrong — the FAIL** |
+
+*"Rows 6 and 7 are the same store shape. The code cannot tell them apart, and
+that is the defect."*
+
+## Finding 1 — the FAIL, and it is a regression against BOTH predecessors
+
+`bin/perry-state:829-841` returns `[dict(DEFAULT_TRACK)], TRACKS_FROM_STORE`
+for any validating store with no `kind: track` record — **unconditionally on
+what the markdown declares.** On a project whose `## Tracks` declares `main`
+and `intake` (queue, 5d) while the store carries settings only —
+a drift `perry-lint` reports as two `config-store-drift` rows:
+
+```
+perry-state --json → tracks[]: [main]   tracks_source: "store"   warnings: []
+perry-diagnose     → register_declared: false, tracks_source: "store"
+perry-task add --track intake
+  → refused — track 'intake' is not declared in `.perry/config.md § Tracks`.
+              Declared: main.
+```
+
+That message is **false about the file it names**: line 14 of that table
+declares `intake`. The tool sends the user to add a row the table already has.
+
+| | tracks | source | warning | `add --track intake` |
+|---|---|---|---|---|
+| `45a355d` | main + intake (5d) | — | none | **written** |
+| `3d2ef25` (round 2) | main + intake (5d) | `no-track-record` | yes | refused, correctly, loudly |
+| `515eff4` (round 3) | **main only** | **`store`** | **none** | refused with a false message |
+
+*"Round 3 loses a declared track and its SLA — from the dashboard, from
+`sla_report`, from `wip_report`, from `--track` validation — **and allows
+writes against the truncated register**, which round 2 did not."*
+
+### `source: store` is not honest, and the dishonesty is load-bearing
+
+The list came from `DEFAULT_TRACK`, a constant. Labelling it `store` asserts a
+provenance the answer does not have — **and that label is precisely what
+silences the warning and the refusal**, both of which are keyed on `source` and
+are correct code given a wrong input.
+
+**The prescribed fix: a fourth source value, `store-default`.** It carries the
+fact the current design throws away — *the store was usable and declared
+nothing, so DESIGN-003's default was applied*. Four one-line decisions:
+
+- **writers**: allowed (round 3 got this right and must keep it).
+- **`perry-state`**: silent on state 6; **warn** on state 7 — the condition
+  `perry-lint` already computes.
+- **`perry-diagnose`**: report `store-default`, not `store`.
+- **`perry-task`'s refusal message**: name the store as the register that
+  answered, not the table that disagrees with it.
+
+> The author's own argument — *"a store that validates and declares zero tracks
+> has ANSWERED"* — is true of state 6 and false of state 7, and the code does
+> not distinguish them. **Two situations, one answer, and the wrong one wins on
+> the one that matters.**
+
+## Finding 2 — the code comment's factual claim is false, disproved by one command
+
+`bin/perry-state:824-825` justifies classifying a zero-record store as
+`invalid` with: *"`perry-config write --from-file` never produces one."*
+
+```
+$ perry-task add --title before …   → wrote TASK-001
+$ perry-config write --from-file    → wrote .perry/config.jsonl (0 records)   [exit 0]
+$ perry-task add --title after …    → refused — … holds records that do not validate …
+$ perry-config verify               → records 0, drift_count 0, byte_identical true
+$ perry-config diff                 → identical true
+$ perry-lint                        → · config store: 0 record(s), 0 row(s) drifted
+$ perry-config write --from-file    → wrote .perry/config.jsonl (0 records)   ← forever
+```
+
+On a `config.md` with no `- Key: value` settings. Round 2's finding 1 with the
+nouns changed, and all three charges hold: the store is not broken, the refusal
+message is false on the project it fires on, and there is no way out through the
+front door.
+
+The good half works: on a settings-bearing config, truncating the store refuses
+writes and `write --from-file` recovers it. *"The trap is that the same command
+is both the recovery and the cause, depending on a property of `config.md` that
+nothing checks."* Narrowest fix is at the **writer** — `perry-config write
+--from-file` should refuse or warn rather than reporting "wrote … (0 records)".
+
+## Finding 3 — a blank track name is silently a default, and it is unguarded
+
+`bin/perry-state:828` filters on `(r.get("track") or "").strip()`. A store with
+one `kind: track` record whose name is blank leaves `rows` empty and lands on
+the default branch. Not reachable through the importer, but **dropping the
+filter entirely is GREEN across all 23 tests**.
+
+## Finding 4 — `perry-task list` still degrades in silence, two rounds old
+
+`TASK-002`'s mode goes `queue` → `""` with empty stderr, while `perry-state`
+warns on the identical state. Measured against my own stated rule — *"what a
+read may never do is stay silent"* — *"it is the rule's own counterexample …
+left in place for a second round with no note in the commit message explaining
+the decision."* Not the FAIL; round 3 did not create it. **It should be filed,
+not carried silently.**
+
+## Finding 5 — the KR reframing is legitimate, but must become an edit
+
+*"A KR cannot be scored against an instrument that would have put its own
+baseline at 11."* So *"0 track-register readings"* is the honest reading. What
+is **not** legitimate is closing `P003-O2-KR1` at 0 while the literal wording
+stands: *"the author's commit message says 'the scoring should say that rather
+than 0', which is the right instinct, and it needs to become an actual edit to
+`phase/003-storage-code.md` rather than a paragraph in a commit message."*
+
+## Mutation record, wrong for the third round running
+
+The diagnose mutation is **2 RED, not 1**, in both the rename and the delete
+form. *"Third round in a row in which the commit message's mutation record does
+not match what the mutation does."*
+
+## What round 3 got right
+
+The `no-track-record` bucket fix is correct and could not be broken — states 6
+and 10 behave exactly as DESIGN-003 specifies, and **all three no-`## Tracks`
+fixtures write again** (verified with a control at `3d2ef25` that reproduces the
+round 2 refusal, so the instrument works). `TestTheGoalsLaneRefusesToo` is a
+real test of a real guard — deleting it is 1 RED where round 2 was green on
+2811. `test_the_register_is_never_empty` closes the unguarded invariant.
+`perry-diagnose` now labels. Both suites red for exactly the reasons `45a355d`
+is red, identical line for line. Neither TASK-228, TASK-211 nor TASK-227
+interferes.
+
+Two smaller items: `stored_tracks`' own docstring table at `bin/perry-state:798`
+still reads `| no-track-record | yes | the counted condition |`, contradicting
+the code 43 lines below; and `tracks_source` is on two published payloads with
+no entry in `schema/` or `reference/`.
+
+## Verdict
+
+```
+=== VERDICT ===
+task: TASK-095
+rung: V4
+result: FAIL
+criteria: perry/evidence/2026-08/TASK-095-spec.md
+proof: bin/perry-state:829-841 returns [dict(DEFAULT_TRACK)], TRACKS_FROM_STORE
+       for any validating store with no `kind: track` record, unconditionally on
+       what `.perry/config.md § Tracks` declares. On a project whose markdown
+       declares main AND intake (queue, 5d) while the store carries settings
+       only — a drift perry-lint reports as 2 rows — perry-state reports
+       tracks[] = [main], tracks_source "store", ZERO warnings; perry-diagnose
+       reports "store"; and `perry-task add --track intake` is refused with
+       "track 'intake' is not declared in `.perry/config.md § Tracks`" pointing
+       at line 14 of a file that declares it. 45a355d returns main+intake and
+       writes the row; 3d2ef25 returns main+intake and refuses loudly. Round 3
+       is worse than both. Second: bin/perry-state:820-826 classifies a
+       zero-record store `invalid` on the stated ground that "perry-config write
+       --from-file never produces one" — it does, on a config.md with no
+       settings, after which every write is refused permanently and re-running
+       the importer re-derives it forever.

+# TASK-095 — V4 review round 4: **FAIL**
+
+> Fresh-context reviewer, 2026-08-29, against `perry/evidence/2026-08/TASK-095-spec.md`.
+> Under review: `1075830`. All destructive work on `git archive` copies.
+
+> **The short version:** *"Round 4 fixes state 7 and, in the same predicate,
+> creates state 8. … Two situations, one answer, and the wrong one wins on the
+> one that matters. Fourth round, fourth time."*
+
+## All four criteria PASS
+
+**C1** 3 `parse_tracks` lines (definition, adoption, and a new comparison at
+`:890` — see (d)). **C2** `project.config.tracks[]` byte-identical, 1671 chars,
+only `tracks_source` added. **C3** all four call-site reverts RED (2/3/1/1).
+**C4** `tests/run` 5 failures at **both** commits; `discover` 2872/8 vs 2786/8,
+sorted `FAIL:` lines diffing to **identical sets**. *"The author's reported
+numbers are exactly right, for the first time this row."*
+
+## Finding 1 — the FAIL. The predicate filters by NAME, not by declaration
+
+`bin/perry-state:891`:
+
+```python
+    named = [n for n in names if n and n != DEFAULT_TRACK["track"]]
+```
+
+`parse_tracks` returns a one-element `main` for **two** reasons and this cannot
+tell them apart: the section is **absent**, so `main` was *synthesised*
+(`declared: False`) — state 6, silence correct; or the table **declares** a row
+named `main`, with its own mode, spine, stages, WIP, SLA and rung
+(`declared: True`) — drift.
+
+**`parse_tracks` already carries the distinguishing flag — `declared` — on
+every row it returns. The predicate ignores it and compares the string.**
+
+Reproduced, with `perry-lint` as the independent control. A table declaring
+`| main | queue | standing | new→triaged→done | 4 | 3d | weekly | V2 |` beside a
+validating store with no track record:
+
+```
+45a355d : main mode=queue   wip='4' sla='3d' spine='standing' rung='V2'
+1075830 : main mode=project wip=''  sla=''   spine=''         rung=''
+          warnings: []      perry-task add: rc=0, wrote TASK-001
+
+perry-lint (state 6) → track drift rows: []
+perry-lint (state 8) → track drift rows: ['track/main — line 12']
+perry-lint (state 7) → ['track/main — line 12', 'track/intake — line 13']
+```
+
+Round 3 prescribed warning on *"the condition `perry-lint` already computes"*.
+`perry-lint` computes *"the table declares a track row the store has no record
+for"*. Round 4 implements *"the table declares a track row whose name is not
+`main`"*. They agree on 6 and 7 and disagree on 8, 9 and 13. **A second
+implementation of one rule, in a file whose own comments cite that defect four
+times** — and the second implementation is the one the payload and both writers
+are keyed on.
+
+The loss is not cosmetic: `wip_report` gets no limit, `sla_report` no clock,
+`stages_of` the project vocabulary instead of `new→triaged→done`, and `add` an
+empty rung instead of V2.
+
+### My own tests assert the defect
+
+The correct predicate — using `parse_tracks`' `declared` flag — matches
+`perry-lint` on **all 21 enumerated states**, and against the shipped module it
+is **3 RED**:
+
+```
+FAIL: test_a_defaulted_answer_over_a_declaring_table_names_what_it_lost
+FAIL: test_a_write_is_fine_with_a_trackless_store
+FAIL: test_goals_is_fine_with_a_trackless_store
+```
+
+Both of the last two call `self.project(setting)` — `md_declares=True` by
+default, which writes a table declaring `main` — so **they assert that a write
+succeeds on state 8**, under docstrings naming the round 2 regression, which bit
+on `md_declares=False`. *"Two of the three regression guards are testing a state
+one step to the side of the one they name, and pinning a defect there."*
+
+That is the fixture trap my own commit message warned about, in the opposite
+direction.
+
+### The mirror asymmetry
+
+| store, same drift | `source` | warns | `add` |
+|---|---|---|---|
+| **zero** track records | `store-default` | yes | **refused** |
+| **one** record, `main` | `store` | no | **allowed**, `intake` silently gone |
+
+*"The rule that decides is 'did the store happen to contain zero track records',
+which is not a fact about the user's situation."*
+
+## The enumeration
+
+21 states across the store axis and the projection axis (absent / main-only /
+main+intake / ragged header / header with zero rows / `## 轨道` localized /
+blank track name / no `config.md`). **14 right, 4 wrong (8, 9, 13, mirror), 1
+recorded limit.** Localization works on state 12 and fails identically on 13.
+
+## Mutation record — correct for the first time in four rounds
+
+All three claims confirmed exactly: 7, 3, 1. Of the reviewer's own nine, six
+red; `:888`'s no-`config.md` branch is **GREEN on 33** — untested.
+
+## (a) Both regression directions hold simultaneously — the first round to manage it
+
+All three no-`## Tracks` fixtures write at head and base with zero
+track-register mentions; state 7 warns and refuses instead of reporting one
+track in silence.
+
+## (b) The state-7 refusal is proportionate, and recoverable
+
+*"Reads stay open, the front door is one documented command, the message names
+it, and `perry-lint` corroborates."* Traced end to end: after the hand edit,
+`add` and `done` refuse, `list` works, `perry-config write --from-file` returns
+the source to `store`, writes resume. **What is not proportionate is the mirror
+asymmetry** — the same question answered two ways depending on a fact the user
+cannot see.
+
+## (c) The refusal writes nothing
+
+Whole-tree SHA-1 over four files, unchanged across four refused writes and two
+reads: `87d752307718a1f857d87d0b3f3fee8803690487`. Stronger than the shipped
+assertion.
+
+## (d) `tracks_the_projection_declares`' `parse_tracks` call
+
+Argued both ways, landing on: *"not a KR violation, and the wrong place to put
+it."* The call is legitimate — a drift warning must look at both sides — but it
+**re-derives a rule `bin/perry-lint` already owns, disagrees with it on three
+states, and that disagreement is finding 1.** *"The right shape is one
+comparison, in one place, that the payload, both writers and the linter all
+read … This is the subtlest question in the round and it is also, on the
+evidence, the root cause."*
+
+## (e) The two carried items
+
+`perry-task list` still silent — third round; filed and now described plainly.
+`P003-O2-KR1` is still literally ≥7, and `git diff 45a355d HEAD --
+perry/phase/003-storage-code.md` is **empty**: the reframing *"has not become
+one"*. The scoping defence is legitimate, but *"anyone scoring it today scores
+it against an instrument nobody has corrected."* `tracks_source` is on two
+published payloads with four values and no entry in `schema/` or `reference/`.
+
+## Interference — and a broken commit I made
+
+**`0d68034` (TASK-213) also carries the `bin/perry-task` half of TASK-095 round
+4.** So at that commit every `perry-task` write on a project with a
+`.perry/config.jsonl` dies with `AttributeError: module 'perry_state' has no
+attribute 'defaulted_over_a_declaring_table'`, and
+`test_track_register_source.py` is 5 failures there. Its message's suite claim
+is false **at that commit**. The tree at `1075830` is whole and both suites
+match `45a355d` exactly, so this is a bisect and bookkeeping defect rather than
+a shipped one — *"but a row's writer half landing under another row's message is
+how the four-call-site miscount happened in the first place."*
+
+## Verdict
+
+```
+=== VERDICT ===
+task: TASK-095

+proof: bin/perry-state:891 — `named = [n for n in names if n and n !=

+       rule it reports for track/intake in state 7, which this commit refuses on.
+       45a355d returns queue/4/3d/standing/V2. Second, same line: the correct
+       `declared`-flag predicate matches perry-lint on all 21 states and is 3 RED,
+       because tests/test_track_register_source.py:445 and :560 build with
+       md_declares=True and therefore ASSERT the allowed write on state 8, under
+       docstrings naming a regression that bit on md_declares=False. Third: the
+       same name filter splits one drift two ways — zero track records warns and
+       refuses, one `main` record is silent and writes.

+# TASK-095 — V4 review round 5: **FAIL**
+
+> Fresh-context reviewer, 2026-08-29, against `perry/evidence/2026-08/TASK-095-spec.md`.
+> Under review: `d77e84d`. All destructive work on copies; the worktree was read-only.
+
+> **The short version:** *"Round 5 fixes state 9 by asking 'does the register
+> hold a record with this name' — and that question, like the four before it,
+> answers two situations as one. A record that **agrees** with the declared row
+> and a record that **contradicts** it are both 'carried'. … Fifth round, fifth
+> time, one step to the left."*
+
+## Criteria
+
+**C1 PASS** — three `parse_tracks` lines, matching the spec's own three roles.
+But `phase/003-storage-code.md:143` still names only two exclusions and no
+drift-comparison reader inside `perry-state`, and round 5 makes that **worse**:
+that third reader is now the sole gate on **every write** in `perry-task` and
+`perry-goals` for every project with a store, and it still disagrees with
+`perry-lint`, which owns the same rule.
+
+**C2 PASS** — `tracks[]` 1671 chars byte-identical; only `tracks_source` added,
+outside the array.
+
+**C3 PASS as written, with a caveat**: all three claimed mutations reproduce
+exactly (2 / 2 / 1). *"Mutations 1 and 2 redden the same two tests, and both
+call the predicate directly. **No payload-level and no writer-level test sees
+round 4's defect.**"*
+
+**C4** — identical at both commits, `diff` of sorted `FAIL:` lines **empty**.
+The reviewer measures **4** failures under `tests/run` where I reported 5.
+**Both are right.** `test_diagnose.test_the_queue_register_reconciles_with_the_queue_on_this_repository`
+reconciles against *this repository's board*; the reviewer's clean `git archive`
+copies carry the board as of the commit, and my worktrees carry the live board
+with the intake rows filed tonight. Re-measured here: 2 failures in
+`test_diagnose` on my trees, 1 on theirs. A data-dependent test, not a
+miscount — but I should have named which tree the number came from.
+
+## The enumeration — 21 states, 18 right, 3 wrong
+
+`S6`, `S8`, `S9`, `S7` and the mirror `M` all behave correctly: **round 4's FAIL
+is fixed and the mirror asymmetry is closed.** The localized `## 轨道` path
+behaves identically to the English one at every state — including the wrong ones.
+
+## Finding 1 — the FAIL. `have` is a set of NAMES, so a contradicting record counts as carrying
+
+`bin/perry-state:942`. The **same one-row table** —
+`| main | queue | standing | new→triaged→done | 4 | 3d | weekly | V2 |` —
+against two stores differing **only** in whether a `kind: track` record for
+`main` exists:
+
+```
+store HAS the record   source=store          mode='project' wip='—' sla='—' rung='V3'
+                       warnings: []          perry-task add rc=0, row written
+                       perry-lint: config-store-drift · track/main —
+                         Mode: file='queue' store='project'; Spine: file='standing'
+                         store='phase/'; Default rung: file='V2' store='V3'
+
+store has NO record    source=store-default  mode='project' wip='' sla='' rung=''
+                       warnings: 1           perry-task add rc=1, nothing written
+                       perry-lint: config-store-drift · track/main — line 12
+```
+
+Same drift, same lint verdict, **opposite responses**, decided by a fact the
+user cannot see. *"That is verbatim the sentence round 4 used to fail the mirror
+asymmetry … Round 5 replaced 'zero records' with 'a record with the same name'
+and left the sentence true."*
+
+**And the file contradicts itself.** `stored_tracks`' docstring says
+`store-default` means *"The store answered: one implicit `main`"*, and
+`TRACKS_ANSWERED` agrees — then forty lines later `have` decides that same
+`main` did **not** answer, because `DEFAULT_TRACK["declared"]` is `False`.
+
+> Either principle would be defensible if applied once:
+> - *"a declared row the register contradicts is drift"* → X1 must warn;
+> - *"the store is truth, the table is a stale projection"* → S8 must be silent.
+>
+> Round 5 takes the first for the synthesised `main` and the second for the
+> recorded `main`.
+
+**No test constructs a record that disagrees with a declared row.** The blind
+spot moved from the name axis to the field axis rather than closing.
+
+## Finding 2 — the widened refusal cannot be cleared by the command it names
+
+Three ordinary hand-edit workflows, each from a store genuinely derived by
+`perry-config write --from-file`:
+
+| workflow | `45a355d` | round 4 | **round 5** | the named remedy |
+|---|---|---|---|---|
+| W1 no section, hand-add a `main` row | writes | writes | **refused** | works |
+| W2 one track, hand-add a second | writes | writes | **refused** | works |
+| W3 two tracks, hand-**swap** one row | writes | writes | **refused** | **rc 1 — refuses** |
+
+On W3 the board is hard-blocked and `perry-config write --from-file` — the only
+command both refusal messages name — exits 1. Its two alternatives each destroy
+one of the two edits. *"Round 4's reviewer passed the narrower refusal precisely
+because 'the front door is one documented command, the message names it'. At
+this width that sentence is false"* — and it is false for a state **this round's
+own untouched blind spot produces**.
+
+## Finding 3 — the `perry-goals` half is a tautological gate
+
+`bin/perry-goals:2168` `if lost:` → `if False:` leaves **the full 2875-test
+suite at exactly the baseline**. `TestTheGoalsLaneRefusesToo`'s own docstring
+records this defect against round 2; the class it produced covers only the
+`unusable` branch and **none of its three tests asserts the `lost` refusal**.
+
+Two more green suite-wide: the no-`config.md` branch (round 4 found it untested;
+unchanged) and the new blank-name filter.
+
+## Carried, each re-measured
+
+`perry-task list` silent — **fourth round**. `tracks_source` undocumented —
+`grep` over `schema/ reference/ work/ goals/ decide/ modes/ templates/` returns
+nothing. `0d68034` still not standalone — *"That reasoning is correct and I
+endorse it — do not rewrite."* And on `P003-O2-KR1` the reviewer **could not
+reproduce round 4's "≥7"**, counting 5 `parse_*` sites of which 3 are named
+exclusions, so the score is 0 or 1; *"I report my number rather than inheriting
+round 4's"* — and the substantive point stands either way: the phase file does
+not name the reader this row created.
+
+## Verdict
+
+```
+=== VERDICT ===
+task: TASK-095
+rung: V4
+result: FAIL
+criteria: perry/evidence/2026-08/TASK-095-spec.md
+proof: bin/perry-state:942 — `have = {t.get("track","") for t in tracks if
+  t.get("declared")}` makes the comparison a set difference on NAMES over
+  records, so a register record that CONTRADICTS the declared row counts as
+  carrying it. One table, two stores differing only in whether a `main` record
+  exists: with it, source=store, mode='project' wip='—' rung='V3', warnings [],
+  `perry-task add` rc=0; without it, source=store-default, 1 warning, rc=1,
+  nothing written — while perry-lint reports the same rule on the same row in
+  both. One drift, one lint verdict, opposite responses, decided by a fact the
+  user cannot see. Second: bin/perry-goals:2168 `if lost:` -> `if False:` leaves
+  the full suite at exactly the baseline. Third: the refusal widened from
+  store-default to store hard-blocks three ordinary hand-edit workflows that
+  write at both 45a355d and 1075830, and on the third `perry-config write
+  --from-file` — the only command either message names — exits 1, so the block
+  cannot be cleared by the documented remedy.

+
+## 1. What changed, and the principle each change follows from
+
+### Decision 1 — principle A, computed by the one thing that owns it
+
+*A declared row the register contradicts is drift.* One principle, everywhere,
+with no second principle for the synthesised `main`.
+
+The root cause across rounds 3, 4 and 5 was a comparison **re-derived on the
+write side**, disagreeing with `perry-lint` on three states each round.
+Round 3 asked "did the store contain zero track records". Round 4 asked "is
+the declared name something other than `main`". Round 5 asked "is the declared
+name absent from the register's list of names". `perry-lint` asks none of
+those: `bin/perry-lint § check_md_store_drift` hands the file and the store's
+validated records to `perry_md_store.plan` — the same plan `perry-config
+render`, `diff` and `verify` are built on — and reads the drifted rows out of
+its report.
+
+**`bin/perry-state § tracks_the_register_contradicts` now makes that same
+call.** Nothing is re-derived. Two of `plan`'s three drift registers name a
+declared row the register contradicts, and both are counted:
+
+- `cells_the_store_and_the_file_disagree_on` — the store HAS a record for this
+  track and it says something else. *This is what round 5 could not see.*
+- `lines_verbatim` — the table declares the row and the store holds no record
+  for it at all (states 7, 8, 9).
+
+The third, `records_not_in_the_file`, is **not** counted, and that is a
+deliberate exclusion rather than an oversight: it is the register declaring a
+track the *table* does not render. It is drift, `perry-lint` reports it, and
+counting it here would put "the register does not carry X" into a warning
+about a track the register is the only side that has. Guarded — see M15.
+
+Three consequences:
+
+- **`tracks_missing_from_the_register` is gone.** It compared a set of NAMES
+  (`have`), which is finding 1 of round 5. It survives as a raising stub
+  beside round 4's `defaulted_over_a_declaring_table`, so a stale caller gets
+  an explanation instead of a silently narrower answer.
+- **`tracks_the_projection_declares` no longer calls `parse_tracks`.** It walks
+  `perry_md_store.CONFIG.scan`, the scanner `perry-lint` walks, which takes
+  both the `## Tracks` heading and every column name from
+  `schema/state-schema.json § i18n`. `grep -n "parse_tracks(" bin/*` is now
+  **two** lines — the definition and the adoption path — where round 5 had
+  three. The third was the drift-comparison reader round 5's reviewer flagged
+  as *"the sole gate on every write … and it still disagrees with
+  `perry-lint`, which owns the same rule."* There is no longer a second
+  spelling of "is this the Tracks section" on the write path.
+- **`_validated_config_records` was extracted.** `stored_tracks` and
+  `tracks_the_register_contradicts` both need "load the store, validate it,
+  say what went wrong"; a second copy of that decision is how this file came
+  to hold two spellings of one rule three rounds running.
+
+**The file's self-contradiction is resolved.** `stored_tracks`' docstring and
+`TRACKS_ANSWERED` said `store-default` means the store ANSWERED; `have`, forty
+lines below, said that same `main` had not. Two orthogonal questions had been
+folded into one flag. They are now separate and both docstrings say so:
+*which register answered* is `stored_tracks`; *does that answer contradict the
+table* is `tracks_the_register_contradicts`, asked identically for `store` and
+`store-default`. The stale comments at `TRACKS_STORE_DEFAULT`,
+`TRACKS_STORE_NO_TRACK_RECORD` (which still named `TRACKS_FROM_STORE` from
+round 3) and `TRACKS_STORE_WHY` were corrected in the same pass.
+
+### Decision 2 — the refusal width reverted to `store-default`
+
+`bin/perry-state § tracks_the_register_cannot_place` is the write refusal, and
+it is deliberately narrower than the drift rule:
+
+- *does the register contradict the table* → drift → **warn**, everywhere;
+- *is there a declared track the register has no row for at all* → the writer
+  cannot stamp `Track`, `Stage`, `Arrived`, the WIP limit or the SLA for that
+  row → **refuse**, and only on `source == store-default`.
+
+Round 4 asked the second question as `name != "main"`. That is the right
+answer on the `store-default` branch — where the register's only row IS `main`
+— and it was the wrong *question*, because round 4 was also using it as the
+drift rule. Asking the register what it returned says the same thing about
+`store-default` without saying anything false about state 8.
+
+`bin/perry-task` and `bin/perry-goals` call it. Both then print the drift
+warning on stderr when they allow the write, so "allowed" is not "silent" —
+which is the failure round 3 and round 4 were failed for on the read side, and
+would have been a fair charge here.
+
+### Decision 3 — the `perry-goals` half now has a test that can fail
+
+`TestTheGoalsLaneRefusesToo` had three tests and none of them reached the
+`lost` branch: all three used fixtures where the table declares nothing the
+register lacks. `test_goals_refuses_when_a_declared_track_has_no_row_at_all`
+uses state 7 (settings-only store, table declaring `main` and `intake`) and
+is **1 RED** when the guard is deleted — M5 below. The guard is kept, not
+deleted.
+
+### `perry-diagnose` — made consistent, not exempted
+
+`scan_work_modes` now carries `tracks_contradicted` beside `tracks_source`,
+and `derive_findings` emits **`MODE-02`** (warn) when it is non-empty,
+documented in `reference/diagnose.md § Finding catalog`. `perry-diagnose` has
+no stderr channel and no refusal — its findings list *is* its warning channel —
+so this is the same signal in the shape that tool has.
+
+Measured on state 7 (item 4):
+
+```
+main 6c0d041   tracks_source='store-default' tracks=['main'] contradicted=(absent) MODE-02=False
+round 6        tracks_source='store-default' tracks=['main'] contradicted=['intake','main'] MODE-02=True
+```
+
+---
+
+## 2. Verification against the amended V4 list
+
+### C1 — the grep
+
+```
+$ grep -n "parse_tracks(" bin/*
+bin/perry-state:566:def parse_tracks(text: str) -> list[dict]:
+bin/perry-state:1109:    return parse_tracks(cfg.read_text(errors="replace")), source
+```
+
+Two lines: the definition, and the adoption/migration path inside
+`declared_tracks_detail` (reached only when the store is `absent`, or present
+and unusable). The four call sites the spec's Baseline names are gone, and so
+is round 5's third, the drift-comparison reader.
+
+### C2 — the payload does not move
+
+`bin/perry-state --root <this worktree> --json`, base binary vs head binary
+over identical data:
+
+```
+tracks byte-identical: True | chars: 1671 1671
+config keys added: []   removed: []   differing: []
+top-level differing keys: ['generated_at']
+tracks_source: store   track warnings: [] both sides
+```
+
+This project's store and its `## Tracks` table agree, so the new rule is
+silent here — which is what "the payload does not move" requires.
+
+### Item 6 — the principle applied ONCE
+
+One table — `| main | queue | standing | new→triaged→done | 4 | 3d | weekly |
+V2 |` — against two stores differing **only** in whether a `kind: track`
+record for `main` exists.
+
+```
+########## main 6c0d041 (round 5) ##########
+  store HAS a `main` record (project/phase//V3)
+    perry-lint    : [... 'track/main']
+    perry-state   : source=store          warnings=0

+    perry-state   : source=store-default  warnings=1
+    perry-task add: exit=1  drift-warned=False  refused=True
+    perry-diagnose: source=store-default  contradicted=(absent)  MODE-02=False
+
+########## round 6 ##########
+  store HAS a `main` record (project/phase//V3)
+    perry-lint    : [... 'track/main']
+    perry-state   : source=store          warnings=1
+    perry-task add: exit=0  drift-warned=True   refused=False

+    perry-goals   : exit=1  drift-warned=True   refused=False
+    perry-diagnose: source=store-default  contradicted=['main']  MODE-02=True
+```
+
+At `main`, one drift, one lint verdict, opposite responses. At round 6 every
+tool gives the same verdict on both stores. `perry-goals` exits 1 on both —
+identically, and for a reason that is not this row's: the fixture's table
+declares `main` as `queue` work, both registers answer `project`, and its
+`OKR.md` has no `## Commitments` section. That is why
+`test_the_goals_lane_gives_the_same_verdict_on_both` asserts an **equality
+between the two runs** rather than `rc == 0`; a test pinned to 0 there would
+be measuring the commitments gate.
+
+Held by `TestOneTableTwoStoresOneVerdict` (7 tests), which carries
+`perry-lint --json` as its own independent control.
+
+### Item 7 — three cases, each named, each tested
+
+| case | fixture | `source` | drift | write |
+|---|---|---|---|---|
+| **trackless** — no `## Tracks`, store carries no track record | `project(SETTING_ONLY, md_declares=False)` | `store-default` | `[]` | allowed, silent |
+| **store-default over a declaring table** — states 7/8/9 | `md_declares=True` / `md_declares_two=True` | `store-default` | `['main']` / `['intake','main']` | refused when a declared name has no row at all |
+| **contradicted declaration** — the store HAS a record and it disagrees | `DECLARING_MAIN` + a `main` record | `store` | `['main']` | allowed, warned |
+
+`test_a_complete_default_loses_nothing`,
+`test_a_table_that_DECLARES_main_is_not_a_complete_default`,
+`test_it_names_every_declared_track_the_register_lacks`,
+`test_the_contradicted_declaration_is_named_by_the_predicate`.
+
+### Item 8 — the three hand-edit workflows, by command and exit code
+
+Each starts from a store genuinely derived by `perry-config write
+--from-file`, then hand-edits `.perry/config.md`, then writes.
+
+```
+                                       main 6c0d041        round 6
+W1  no `## Tracks` → add a `main` row   add exit=1  ✗       add exit=0  ✓ (warned)
+W2  one track      → add a second       add exit=1  ✗       add exit=0  ✓ (warned)
+W3  two tracks     → swap one row       add exit=1  ✗       add exit=0  ✓ (warned)
+    W3's named remedy, both trees:      perry-config write --from-file  exit=1
+```
+
+Full transcript at round 6:
+
+```
+=== W1 ===
+$ perry-config write --from-file --root …/W1                     exit=0
+$ perry-task add --title t … --root …/W1                          exit=0
+  ⚠ the track register disagrees with `.perry/config.md § Tracks` on main.
+  tasks.jsonl written: True
+=== W2 ===
+$ perry-config write --from-file --root …/W2                     exit=0
+$ perry-task add --title t … --root …/W2                          exit=0
+  ⚠ the track register disagrees with `.perry/config.md § Tracks` on intake.
+  tasks.jsonl written: True
+=== W3 ===
+$ perry-config write --from-file --root …/W3                     exit=0
+$ perry-task add --title t … --root …/W3                          exit=0
+  ⚠ the track register disagrees with `.perry/config.md § Tracks` on ops.
+  tasks.jsonl written: True
+$ perry-config write --from-file --root …/W3                     exit=1
+  ⎿ refusing to overwrite … 1 stored value(s) would be replaced:
+      track/intake: in the store, no line in the file — the whole record would be dropped
+```
+
+**A correction to the reconstruction, stated because it matters.** "Hand-swap
+one row" has two readings and only one reproduces the round 5 reviewer's
+measurement. Replacing the second declared row with a row for a *differently
+named* track (`intake` → `ops`) is refused at `main` **and** its named remedy
+exits 1 — the reviewer's W3 exactly. Keeping the name and changing the row's
+cells already wrote at `main` (round 5 compared names), so it is not one of
+the three blocked workflows; it is kept as `test_W3b…` because it is the shape
+whose stored cells the remedy would overwrite. Both were measured on both
+trees before choosing.
+
+Held by `TestTheThreeHandEditWorkflowsStillWrite` (6 tests), including
+`test_the_named_remedy_really_does_fail_on_W3`, which asserts the remedy still
+exits 1 — so if `perry-config write --from-file` is ever fixed, the argument
+for the narrower refusal weakens *in a test* rather than in a paragraph nobody
+re-measures.
+
+### Item 10 — the localized path
+
+`## 轨道` with `| 轨道 | 模式 | 主线 | 阶段序列 | 在制上限 | 时限 | 周期 |
+默认验证级 |` behaves identically to the English table at both states, and it
+does so because the heading and every column name come from
+`schema/state-schema.json § i18n` — the same source `perry-lint` reads.
+`test_the_localized_table_behaves_identically` asserts the lint verdict and
+the predicate agree between the two spellings, and M12 (removing `^轨道` from
+the schema) reddens it.
+
+---
+
+## 3. Every mutation
+
+Harness: anchor by line number, `assert` the old text at that line before
+replacing it, clear every `__pycache__`, sleep past the whole-second boundary,
+run with `PYTHONDONTWRITEBYTECODE=1`, restore, verify by `md5`. **Every entry
+below reports `restored: OK`**, and an anchor that did not match is reported
+as `ANCHOR MISS → NOT RUN` rather than as a green.
+
+Runner for all of them: `python3 -m unittest test_track_register_source` from

+
+**33 mutations, 33 `restored: OK`, 0 `MISMATCH`, 0 `ANCHOR MISS`.** (28 before the V4 review, 5 after it: M23–M27.) The harness
+prints `ANCHOR MISS → NOT RUN` rather than a verdict when the line does not
+carry the expected text, because a mutation whose anchor did not match reports
+a meaningless "OK" and that has happened on this row.
+
+### Mutations that came back GREEN — reported, not counted
+
+**These are findings, not passes.**
+
+- **M11** — `perry-state:1058`, `have = {(t.get("track") or "") for t in
+  tracks}` → `have = {DEFAULT_TRACK["track"]}` (round 4's literal). GREEN, and
+  **provably equivalent**: the function returns early unless `source ==
+  store-default`, and on that branch `stored_tracks` returns exactly
+  `[dict(DEFAULT_TRACK)]`, so the two expressions cannot differ. What the
+  rewrite buys is not behaviour on this branch — it is that the line says what
+  it means, and does not generalise wrongly if the branch ever widens. **This
+  is the one place where round 4's failed literal is still behaviourally
+  intact**, and it is stated here rather than hidden behind a green.
+- **M13** and **M14** *individually* — the two filters in
+  `tracks_the_projection_declares` **mask each other**: a settings site carries
+  no `track` value, so dropping the kind filter leaks a blank the blank filter
+  catches; and `perry_md_store.CONFIG.scan` already drops a `## Tracks` row
+  whose first cell is empty, so dropping the blank filter leaks nothing the
+  kind filter has not already excluded. Each alone is an equivalent mutant. The
+  pair is guarded (M13+M14 above), and `TestWhatTheProjectionDeclares` states
+  the masking in its own docstring so the next round does not rediscover it as
+  a defect.
+- **M24** — `perry-state:1006`, `if good is None:` → `if False:` in
+  `tracks_the_register_contradicts`. GREEN. The function returns early unless
+  `source in TRACKS_ANSWERED`, and both members of that set imply
+  `_validated_config_records` returned records, so on every path a caller can
+  reach today the branch is dead. It is kept as a guard against the TOCTOU
+  window — `source` is computed from disk by the caller a moment earlier, and
+  the store can be replaced in between — and that race is not something this
+  module can construct. Unreachable by construction, defensive on purpose.
+- **M25** — `perry-state:1020`, the `ln.get("kind") == "track"` filter on the
+  `lines_verbatim` half → `if True`. GREEN, and **masked by M23**: a
+  `lines_verbatim` entry for a setting line carries the key `setting/…`, which
+  the `startswith("track/")` filter two lines below already drops. The two are
+  redundant; the lower one is the one that does the work, and it is guarded.
+  Left in place rather than removed, because the row had already PASSED and
+  widening a passing change is how rounds 2, 3 and 5 failed.
+- **M20** (`perry-state:933`) and **M21** (`:1003`) — the `cfg.exists()` fast
+  paths in `tracks_the_projection_declares` and
+  `tracks_the_register_contradicts`. GREEN and equivalent: both functions wrap
+  the read in `try/except` and return `[]`, so removing the fast path reaches
+  the same answer by a slower route. The third such branch, M22 in
+  `declared_tracks_detail`, has **no** `try/except` — it was a real crash path,
+  it was GREEN at rounds 4 and 5, the round 4 review recorded it, and it is
+  closed here.
+
+### Addendum after the V4 PASS — the reviewer's one finding
+
+The round 6 review PASSED and named one non-blocking gap: **a guard this round
+ADDED survived its own deletion.** Replacing `bin/perry-state:1022`'s
+`if k.startswith("track/") and "/" in k}` with `if "/" in k}` left all 56 tests
+green, and the line was absent from the table above.
+
+The shipped code is correct; the missing thing was the test.
+`cells_the_store_and_the_file_disagree_on` is **not** filtered by record kind —
+it carries `setting/…` keys beside `track/…` ones — so that filter is the only
+thing keeping a hand-edited setting out of an answer about the track register.
+
+Reproduced before fixing, on a project whose `## Tracks` row AGREES with the
+store cell for cell and whose store was derived by `perry-config write
+--from-file`, then with ONE setting hand-edited (`- Document language: English`
+→ `中文`):
+
+```
+with the filter (shipped):
+  $ perry-task add …            exit=0   no track-register line on stderr
+without the filter (mutant):
+  $ perry-task add …            exit=0
+    ⚠ the track register disagrees with `.perry/config.md § Tracks` on
+      document_language. This command answers from the REGISTER. …
+```
+
+A sentence about the track register, naming a setting, pointing at a section
+that does not contain it.
+
+`test_a_hand_edited_SETTING_is_not_reported_as_a_track` asserts on **that
+sentence**, not on the predicate's return value, because the sentence is the
+harm. It carries `perry-lint --json` as its own control, asserting the fixture
+really does drift (`['setting/document_language']`) so it cannot pass on a
+clean project. M23 above is the mutation: **1 RED, and it is that test.**
+
+Auditing the rest of the table rather than only the line the reviewer named
+added M24–M27. Two more guards are green and both are explained under
+*Mutations that came back GREEN*; two were real and are now covered.
+
+**Nothing else was changed.** The diff of this addendum is one test method
+(+40 lines in `tests/test_track_register_source.py`) and this section. No
+`bin/` file moved.

+
++21 tests is this row's own, exactly: `test_track_register_source` goes from
+**36 to 57** test methods, measured with `python3 -m unittest
+test_track_register_source` from `tests/` on each tree. No other module gained
+or lost a test. The last of the 21 is
+`test_a_hand_edited_SETTING_is_not_reported_as_a_track`, added after the V4
+PASS; the run that measured 2903 took 677s under a machine load average of 37
+to 39 from other agents, which is why it is slower than the 296s run above and
+not why any number differs.
+
+**Two warnings about these numbers, both learned the expensive way.**
+
+1. **The tree is part of the baseline.** `test_diagnose`'s queue-register test
+   reconciles against the LIVE board, so a tree carrying different intake rows
+   gives a different number. Both rows above are the board **as committed at
+   `6c0d041`**; a worktree carrying tonight's filed rows measures differently
+   and that is not a miscount. The spec amendment quotes 98/2882/3 for `main`
+   at `70eae67` and this reproduces it exactly at `6c0d041`.
+2. **My first baseline was contaminated and is discarded.** I started
+   `bash tests/run` in the worktree and then began editing `bin/perry-state`
+   while it ran; `test_task_writer` (which shells out to `perry-task`) came
+   back with 10 failures and 8 errors that were my own half-applied edit. The
+   number above is from a `git archive` copy at `base-6c0d041/`, untouched for
+   the whole run. Recorded because "98/2882/3" is worth nothing without saying
+   which bytes produced it.
+
+`unittest discover` was not used for either row. The amendment records that it
+shows 3 more from a module-double-import artifact in `test_risks_store`; I did
+not re-measure that and do not report a number for it.
+
+---
+
+## 5. What I did not do, and what I could not verify
+
+- **`perry-config write --from-file` is untouched.** It writes a zero-record
+  store at exit 0 on a `config.md` with no settings, and it exits 1 on W3 —
+  it is both the cause and the only offered recovery. USER-905 names it as a
+  separate filed row and the narrower refusal exists precisely because of it.
+  `test_the_named_remedy_really_does_fail_on_W3` pins the current behaviour so
+  that fixing it surfaces here.
+- **`perry-task list`'s blank `mode` cell is not fixed.** Four review rounds
+  have carried it. This change makes the command *say* the register disagrees
+  (stderr, on every command including reads); it does not change what the
+  `mode` cell reports. That is a different defect about a different field.
+- **`P003-O2-KR1`'s wording is untouched.** `perry/phase/003-storage-code.md`
+  still reads *"call sites in `bin/` that read a projected markdown file as
+  truth while its store exists"*, which literally also counts the six
+  `kind: setting` reads at `bin/perry-state:126-135` and `Conformance gate` at
+  `bin/perry-conform:304`. Rounds 2–5 all recorded that the honest score is
+  *"0 track-register readings"*; round 4 counted the literal residue at ≥7 and
+  round 5 could not reproduce that number and counted 0–1. **I did not
+  re-count it and I did not edit the phase file** — the PMO owns that file and
+  the amendment did not ask for it. Anyone scoring the KR today is still
+  scoring it against an instrument nobody has corrected.
+- **`tracks_source` and now `tracks_contradicted` are on two published
+  payloads with no entry in `schema/` or `reference/`.** `MODE-02` is
+  documented in `reference/diagnose.md § Finding catalog`; the two payload
+  fields are not. Carried, not fixed.
+- **I did not run `perry-diagnose`'s execute stage, `adopt`, `relocate` or any
+  write-side tool against `/Users/bytedance/proj/Perry`.** Every destructive
+  probe ran in `…/scratchpad/wtest/` or in a `tempfile.mkdtemp` fixture. The
+  `## Intake` filing of the `perry-config` defect is not on this branch; the
+  PMO owns `perry/BOARD.md` and `perry/tasks.jsonl` and I did not touch either.
+- **Not measured:** Windows paths; multi-repo layouts where the state root is
+  not the project root; whether the three pre-existing failures are real
+  defects or stale expectations; any language other than `en` and `zh`; the
+  `viewer/` readers; `perry-conform`'s `Conformance gate` read.
+- **One judgement call worth a reviewer's attention.** The drift warning is
+  printed by `perry-task` on **every** command, reads included, and by
+  `perry-goals` on the commit path. That is new output on stderr where there
+  was none. It is not required by the amendment; I added it because allowing a
+  write over drift in silence is the same shape rounds 3 and 4 were failed
+  for, and because the amendment's item 6 asks for one verdict from every
+  tool. If a reviewer judges the extra stderr line out of scope, it is M8/M6
+  and deletes cleanly.

+# TASK-095 — V4 review round 6: **PASS**
+
+> Fresh-context reviewer, 2026-08-29. Under review: `a917a43`, tip of
+> `coding/task-095-round6`, forked from `main` at `6c0d041`.
+> Graded against `perry/evidence/2026-08/TASK-095-spec.md`, whose
+> **Amendment 2026-08-29 — USER-905** binds.
+>
+> **Every destructive probe ran on copies.** Two clean `git archive` trees
+> (`base-6c0d041/`, `head-a917a43/`) plus a third (`mut/`) for mutation. The
+> reviewed worktree was never written to; no write-side Perry tool was pointed
+> at `/Users/bytedance/proj/Perry` or at the worktree. Fixture roots were
+> `tempfile.mkdtemp` directories. No identifiers were minted.
+
+> **The short version:** *"Round 5's defect is closed and closed at the right
+> place — the write side no longer owns a fourth copy of the drift rule, it
+> calls `perry_md_store.plan`, the same call `perry-lint` makes. I rebuilt the

+> mutant: drop `k.startswith("track/")` at `bin/perry-state:1022` and a
+> hand-edited SETTING is reported as a contradicted TRACK, with all 56 tests
+> green."*
+
+---
+
+## Verdict on the claim I was told to attack first
+
+**The M11 equivalence argument is CORRECT.** I decided it by reading the
+control flow, not by trusting the RESULT.
+
+`bin/perry-state § tracks_the_register_cannot_place` (1055–1060):
+
+```python
+if source != TRACKS_STORE_DEFAULT:
+    return []
+have = {(t.get("track") or "") for t in tracks}
+```
+
+`tracks` is the caller's list. Both production call sites derive it from the
+same call that produced `source`:
+
+```
+bin/perry-task:6748    tracks, source = _ps.declared_tracks_detail(project_root)
+bin/perry-task:6783    _lost = _ps.tracks_the_register_cannot_place(project_root, tracks, source)
+bin/perry-goals:2156   tracks, source = ps.declared_tracks_detail(project_root)
+bin/perry-goals:2168   lost = ps.tracks_the_register_cannot_place(project_root, tracks, source)
+```
+
+`declared_tracks_detail` returns `stored` unchanged when `stored is not None`,
+and `stored_tracks` reaches `TRACKS_STORE_DEFAULT` on exactly one `return`
+statement: `return [dict(DEFAULT_TRACK)], TRACKS_STORE_DEFAULT`
+(`bin/perry-state:897–908`). So on the only branch the source gate lets
+through, `tracks == [DEFAULT_TRACK]` and `have == {DEFAULT_TRACK["track"]}`.
+The two expressions cannot differ. Reproduced: M11 GREEN, 56/56, `restored OK`.
+
+**And that is not a live gap, because it is what the amendment asked for.**
+Round 4's failure was filtering on the NAME `main` *as the drift rule*.
+USER-905 Decision 2 reverts the *refusal* to round 4's width — `source ==
+store-default` — deliberately. Round 4's literal is behaviourally intact on a
+branch where the amendment says it should be. The drift rule, which is the
+thing round 4 was failed for, is now `perry-lint`'s and is nowhere near this
+line. The author states this rather than hiding it behind a green; that is the
+right call.
+
+**The other three greens, ruled on:**
+
+- **M13 / M14 individually** (`perry-state:946`, `:949`) — mutual masking
+  confirmed by reading `perry_md_store.CONFIG.scan`: a `## Tracks` row whose
+  first cell is empty is already dropped by the scanner, and a settings site
+  carries no `track` value. Each alone is equivalent; the pair is guarded
+  (M13+M14 → 9 RED). Accepted, and `TestWhatTheProjectionDeclares`' docstring
+  records the masking so the next round does not re-find it.
+- **M20 / M21** (`perry-state:933`, `:1003`) — both functions wrap the read in
+  `try/except … return []`, so the `cfg.exists()` fast path is a shortcut to
+  the same answer. Accepted. The third such branch, M22 in
+  `declared_tracks_detail`, has **no** `try/except`; I ran it and it is
+  **1 ERROR** (`test_an_unusable_store_with_no_config_md_beside_it_still_answers`),
+  so the one that was a real crash path is closed.
+
+---
+
+## Item by item, with the measurement
+
+Runner and tree are named on every number. `bash tests/run` and
+`python3 -m unittest discover -s tests` disagree on this repository, and
+`test_diagnose`'s queue-register test reconciles against the live board, so
+both trees below are clean `git archive` copies of the committed board.
+
+### 1. Principle A applied ONCE — **VERIFIED**
+
+*Is `tracks_the_register_contradicts` the same comparison `perry-lint` makes,
+or a second implementation that agrees today?* **The same one.** Read both:
+
+| | `bin/perry-lint § check_md_store_drift` | `bin/perry-state § tracks_the_register_contradicts` |
+|---|---|---|
+| loads | `load_store` → `validate_records` | `_validated_config_records` → same two calls |
+| compares | `_MD_STORE.plan(doc, text, good)["report"]` | `md_store.plan(md_store.CONFIG, text, good)["report"]` |
+| counts | `cells_…disagree_on` + `lines_verbatim` + `records_not_in_the_file` | `cells_…disagree_on` + `lines_verbatim` (kind==track) |
+
+Nothing is re-derived. The read side is a strict **subset** of the linter's
+drifted-row set, and the one exclusion (`records_not_in_the_file` — the
+register declaring a track the table does not render) is documented, argued,
+and guarded: M15 (counting it) is **2 RED**, `test_a_healthy_store_warns_about_nothing`
+and `test_an_agreeing_register_gets_no_finding`.
+
+**I built the amendment's fixture from scratch** — my own script, not the
+author's helpers — one table
+`| main | queue | standing | new→triaged→done | 4 | 3d | weekly | V2 |`
+against two stores differing only in whether a contradicting
+`kind: track / main` record exists. Five tools, both trees
+(`scratchpad/rv/probe/item1.py`):
+
+```
+######## base-6c0d041 (rounds 2–5)
+  store HAS a contradicting `main` record

+
+At `main`: one lint verdict, opposite responses. At round 6: every tool gives
+the identical verdict on both stores. This reproduces the author's item-6 table
+exactly and independently. `perry-goals` rc=1 on **both** — I checked why, and
+it is the commitments gate on the fixture's `OKR.md`, identical on both sides
+and not a track-register refusal (`"the track register does not carry"` appears
+in neither). `test_the_goals_lane_gives_the_same_verdict_on_both` asserting an
+equality rather than `rc == 0` is therefore the correct instrument, not an
+evasion.
+
+### 2. `grep -n "parse_tracks(" bin/*` is two lines — **VERIFIED**
+
+```
+head-a917a43:  bin/perry-state:566   def parse_tracks(text: str) -> list[dict]:
+               bin/perry-state:1109      return parse_tracks(cfg.read_text(errors="replace")), source
+base-6c0d041:  bin/perry-state:566, :900, :975            (three)
+```
+
+The third — round 5's drift-comparison reader, the one round 5's reviewer
+flagged as *"the sole gate on every write … and it still disagrees with
+`perry-lint`"* — is gone. `tracks_the_projection_declares` now walks
+`perry_md_store.CONFIG.scan`, so the heading and every column name come from
+`schema/state-schema.json § i18n`. Original spec criterion 1 asked for
+definition + adoption + drift-comparison "and nothing else"; two is a superset
+of satisfying it.
+
+### 3. The refusal reverted to `store-default` — **VERIFIED**
+
+Reconstructed independently (`scratchpad/rv/probe/item3.py`); each case derives
+its store with `perry-config write --from-file`, hand-edits `.perry/config.md`,
+then writes.
+
+| workflow | `base-6c0d041` | `head-a917a43` |
+|---|---|---|
+| W1 no `## Tracks` → add a `main` row | `add exit=1`, nothing written | **`add exit=0`**, `tasks.jsonl` written, stderr `⚠ … on main` |
+| W2 one track → add a second | `add exit=1`, nothing written | **`add exit=0`**, written, stderr `⚠ … on intake` |
+| W3 two tracks → swap one row (`intake`→`ops`) | `add exit=1`, nothing written | **`add exit=0`**, written, stderr `⚠ … on ops` |
+
+Named remedy `perry-config write --from-file`, re-run after the hand edit:
+W1 `exit=0`, W2 `exit=0`, **W3 `exit=1`** — *"refusing to overwrite … track/intake:
+in the store, no line in the file — the whole record would be dropped"* — on
+**both** trees. Round 5's finding 2 reproduces, and round 6 removes it.
+
+### 4. W3's named remedy is PINNED, not restated — **VERIFIED by simulation**
+
+`test_the_named_remedy_really_does_fail_on_W3` asserts `assertNotEqual(rc, 0)`.
+To prove it pins rather than restates, I simulated the fix: in `mut/`,
+`bin/perry_md_store.py:960` `losses = would_discard(on_disk, derived)` →
+`losses = []`.
+
+```
+SIM [bin/perry_md_store.py:960] Ran 56 tests  FAILED (failures=1)  restored=OK
+   RED(1): ['test_the_named_remedy_really_does_fail_on_W3']
+```
+
+Exactly that one test, and only it. If `perry-config write --from-file` is ever
+fixed, the argument for the narrower refusal weakens in a test. **Caveat:** it
+pins the exit code, not the *reason* — a refusal from a different branch of
+`perry-config` would keep it green.
+
+### 5. The `perry-goals` guard is no longer a tautology — **VERIFIED**
+
+```
+M5 [bin/perry-goals:2169]  `if lost:` → `if False:`
+   Ran 56 tests  FAILED (failures=1)  restored=OK
+   RED(1): ['test_goals_refuses_when_a_declared_track_has_no_row_at_all']
+```
+
+Round 5 measured this mutation leaving the **full** suite at baseline. It is
+now 1 RED. The test reaches the branch through state 7 (settings-only store,
+table declaring `main` **and** `intake`) and asserts both the message and that
+it names `intake` — not a generic non-zero exit. Decision 3 is satisfied by
+keeping the guard with a real test, which is the option the amendment allows.
+
+### 6. `perry-diagnose` made consistent — state 7 on all four — **VERIFIED**
+
+My own state-7 fixture, both trees, EN and ZH (`scratchpad/rv/probe/state7.py`):
+
+```
+head-a917a43   perry-lint     : ['track/intake', 'track/main']
+               perry-state    : source='store-default'  1 warning
+               perry-task add : rc=1 refused=True
+               perry-goals    : rc=1 refused=True
+               perry-diagnose : contradicted=['intake','main']  MODE-02=True   ← was silent
+base-6c0d041   perry-diagnose : contradicted=(absent)           MODE-02=False
+```
+
+`MODE-02` is in `WHY`, so `finding_code_re()` picks it up, and the catalog row
+landed under `reference/diagnose.md § Finding catalog` at line 476, between
+`MODE-01` and `FIT-01` — the right table under the right heading (I checked,
+because "a section landing under the wrong heading" is on this project's list).
+
+**One residual, measured not reasoned:** on state 7 `perry-task list` exits 0
+and says nothing, because the stderr warning is gated `if _drift and not
+_lost:` and state 7 is the `_lost` case. That is identical at `base-6c0d041`,
+so it is not a regression — but the fourth-round `perry-task list` finding is
+not fully closed by this change, and the RESULT says as much.
+
+### 7. Localization — **VERIFIED**
+
+`## 轨道` with `| 轨道 | 模式 | 主线 | 阶段序列 | 在制上限 | 时限 | 周期 |
+默认验证级 |` gives byte-identical answers to the English table at state 7 and
+at both stores of the item-1 comparison, on all five tools (table above). And
+the schema is load-bearing:
+
+```
+M12 [schema/state-schema.json:2058]  "^Tracks\b|^轨道" → "^Tracks\b"
+   Ran 56 tests  FAILED (failures=2)  restored=OK
+   RED(1): ['test_the_localized_table_behaves_identically']
+```
+
+That test is not a self-grep: it compares `lint_track_rows(zh)` to
+`lint_track_rows(en)` **and** pins `["main"]`, so two empty lists cannot
+satisfy it.
+
+### 8. 28 mutations, 0 anchor misses, 0 md5 mismatches — **SPOT-CHECKED, 17 of them**
+
+First, **all 27 anchors the RESULT names carry exactly the text it claims** —
+I printed every one by line number. No anchor miss is possible on the reported
+set.
+
+Then I re-ran 17 mutations myself in `mut/` (own harness: assert-old-text at
+the line, clear `__pycache__`, `PYTHONDONTWRITEBYTECODE=1`, restore, `md5`
+compare). Runner: `python3 -m unittest test_track_register_source` from
+`mut/tests/`, 56 tests. **Every one matched the RESULT's `failures=` count and
+its RED test names, and every one restored `OK`:**
+
+```
+M1  perry-state:1018   failures=8  7 RED   (the round-5 rule; matches the RESULT's 7 names)
+M2  perry-state:1019   failures=9  8 RED
+M3b perry-task:6783    failures=7  6 RED
+M4  perry-state:1000   failures=3  1 RED
+M5  perry-goals:2169   failures=1  1 RED
+M6  perry-goals:2179   failures=2  1 RED
+M7  perry-task:6785    failures=2  2 RED
+M8  perry-task:6803    failures=4  3 RED
+M9  perry-diagnose:2212 failures=2 2 RED
+M11 perry-state:1058   OK — 0 RED  (equivalent, ruled on above)
+M12 schema:2058        failures=2  1 RED
+M15 perry-state:1019   failures=2  2 RED
+M16 perry-state:833    failures=6  6 RED
+M19 perry-state:894    failures=1  1 RED
+M22 perry-state:1107   errors=1    1 ERROR
+C3d perry-diagnose:1910 failures=2 2 RED
+SIM perry_md_store:960 failures=1  1 RED   (my own, item 4)
+```
+
+Both exact reverts the amendment names are in there: **M1** (round 5's
+name-set rule, `keys = set()`) and **M3b** (round 5's refusal width). Both go
+red, hard.
+
+### 9. Baselines — **VERIFIED, both trees, both runners**
+
+**Runner `bash tests/run`**, clean `git archive` copies, the board as committed:
+
+| tree | commit | modules | tests | failures |
+|---|---|---|---|---|
+| `base-6c0d041/` | `6c0d041` | 98 | 2882 | 3 |
+| `head-a917a43/` | `a917a43` | 98 | 2902 | 3 |
+
+`diff` of the sorted failure lines: **empty**. The three, identical on both:
+
+```
+test_diagnose … test_the_queue_register_reconciles_with_the_queue_on_this_repository
+test_diagnose.TestUserLoadFindings.test_perry_itself_passes_its_own_id_checks
+test_kr_progress_provenance … test_no_current_in_the_payload_claims_to_be_a_measurement
+```
+
+`+20` is exactly this row's: `python3 -m unittest test_track_register_source`
+from `tests/` gives **36** on base and **56** on head. 2902 − 2882 = 20. No
+other module moved.
+
+**Runner `python3 -m unittest discover -s tests`** — the original spec's
+criterion 4, which the RESULT explicitly declined to measure. I measured it:
+see the block at the end of this file.
+
+### Criterion 2 of the original spec — the payload does not move — **VERIFIED**
+
+Base binary and head binary over identical data (`head-a917a43/`'s own state):
+
+```
+tracks byte-identical: True | chars: 1671 1671
+tracks_source: store  →  store
+config keys added: []  removed: []  differing: []
+top-level differing keys: ['generated_at']
+base track warnings: []   head track warnings: []
+perry-task list  base rc=0 stderr=''   head rc=0 stderr=''
+```
+
+1671 chars, matching the round-5 reviewer's number. The new rule is silent on
+this project, and `perry-task list` gains no output here.
+
+---
+
+## Ruling on the author's judgement call — the new stderr warning
+
+**In scope, correct, and it widens nothing. Keep it.**
+
+- **In scope.** Amendment item 6 requires *one verdict from every tool* on the
+  two-store comparison. Without the warning, `perry-task` and `perry-goals`
+  would allow the write silently while `perry-lint` and `perry-state` reported
+  drift — four tools, two verdicts. The author is right that "allowed in
+  silence" is the shape rounds 3 and 4 were failed for.
+- **Correct.** It fires exactly where `tracks_the_register_contradicts` is
+  non-empty, which I verified is `perry-lint`'s own rule.
+- **It widens nothing — measured, not reasoned.** Three workflows that were
+  clean before, base binary vs head binary
+  (`scratchpad/rv/probe/noise.py`):
+
+```
+                                            base-6c0d041          head-a917a43
+healthy: two-track table, store derived     add rc=0, list rc=0   IDENTICAL (byte-for-byte stderr)
+healthy: no ## Tracks, store derived        add rc=0, list rc=0   IDENTICAL
+adoption: table, NO store at all            add rc=0, list rc=0   IDENTICAL
+                                            0 track warnings      0 track warnings
+```
+
+No new stderr line, no new refusal, no exit-code change on any of them. The
+only exit-code changes I found anywhere go **1 → 0** (W1/W2/W3). Nothing goes
+0 → 1. `perry-goals` gains the same line on every command except `link`
+(`tracks_of` is in the shared `ctx`), which is stderr only and does not touch
+the `list` payload contract. Both halves delete cleanly (M6 → 1 RED, M8 →
+3 RED), so if a later round disagrees the cost is one line each.
+
+---
+
+## The one finding the RESULT does not report
+
+**A guard this round ADDED survives its own deletion, and it is not an
+equivalent mutant.** `bin/perry-state:1022`:
+
+```python
+return sorted({k.split("/", 1)[1] for k in keys
+               if k.startswith("track/") and "/" in k})
+```
+
+`keys` is seeded from `report["cells_the_store_and_the_file_disagree_on"]`,
+which is **not** filtered by kind — it carries `setting/…` keys too
+(`perry_md_store § record_key` renders a setting as `setting\x00<key>`, which
+becomes `setting/<key>`). The `track/` prefix is the only thing keeping a
+drifting *setting* out of a warning about *tracks*. Drop it:
+
+```
+X1 [bin/perry-state:1022]  `if k.startswith("track/") and "/" in k}` → `if "/" in k}`
+   Ran 56 tests   OK   0 RED   restored=OK
+```
+
+**All 56 green.** And it is a real behaviour change, not an equivalent mutant.
+Fixture: a `## Tracks` table whose one row agrees with the store, and one
+hand-edited *setting* (`- Last updated:`), the ordinary shape of every one of
+this round's own W-workflows (`scratchpad/rv/probe/x1.py`):
+
+```
+CLEAN head:   perry-lint drift rows: ['setting/last_updated']
+              tracks_the_register_contradicts -> []
+              perry-task add rc=0, no drift line
+
+with X1:      perry-lint drift rows: ['setting/last_updated']
+              tracks_the_register_contradicts -> ['last_updated']
+              perry-task add rc=0, stderr:
+              "⚠ the track register disagrees with `.perry/config.md § Tracks`
+               on last_updated. This command answers from the REGISTER."
+```
+
+A setting named as a track, on every command, on the most common hand edit
+there is — and the module cannot see it.
+
+**Why this is a finding and not the FAIL.** The shipped code is *correct*: the
+filter is there and every state I measured answers right. The RESULT's headline
+claim ("28 mutations, 28 `restored: OK`, 0 anchor misses") is true as stated;
+this is a 29th guard that was not mutated and not listed under *"Every other
+guard this change touches"*, where it belongs. It is a test-coverage gap in a
+round whose whole subject is that gates whose green is a tautology are worse
+than no gate. The fix is one test:
+
+```python
+def test_a_drifting_SETTING_is_not_reported_as_a_track(self):
+    # `cells_the_store_and_the_file_disagree_on` is not filtered by kind
+    ...  # assert tracks_the_register_contradicts(...) == []
+```
+
+---
+
+## Residuals — checked, and not FAILs
+
+- **Order drift diverges from `perry-lint`, silently.** Swap two rows of
+  `## Tracks` by hand, cells identical: `perry-lint` reports
+  `config-store-drift · \`track\` — the rows of this register sit in a
+  different order`, while `perry-state`, `perry-task`, `perry-goals` and
+  `perry-diagnose` all say nothing (`scratchpad/rv/probe/order.py`, head).
+  Defensible under principle A **as written** — the register holds an identical
+  record for that declared row, so nothing is contradicted — and it matches
+  `perry-lint`'s own `stats["drifted"]` row count, which also excludes order.
+  Unlike the `records_not_in_the_file` exclusion, this one is neither
+  documented in the RESULT nor guarded by a mutation. Worth a line in the next
+  round's record.
+- **`cells_wearing_decoration`** is likewise excluded; `perry-lint` reports it
+  under a *different* rule (`config-store-decorated`) and does not count it as
+  a drifted row either. Consistent.
+- **`if good is None: return []`** inside `tracks_the_register_contradicts` is
+  unreachable given the `TRACKS_ANSWERED` gate above it (barring a TOCTOU
+  delete between the two loads). Equivalent by construction; the docstring says
+  so.
+
+## What the author did NOT do — all three genuinely out of scope
+
+- **`perry-config write --from-file`.** The amendment names it as *"a separate
+  filed row"* and says *"Do not widen again until [it] is fixed."* Leaving it
+  untouched is not a dropped requirement, it is the instruction. I confirmed
+  the defect is real on both trees (W3 remedy `exit=1`) and that it is pinned.
+- **`perry-task list`'s blank `mode` cell.** Never a criterion of the original
+  spec or the amendment; carried as a review observation since round 2. Not
+  fixed, correctly named as not fixed.
+- **`P003-O2-KR1`'s wording** in `perry/phase/003-storage-code.md`. The
+  amendment does not ask for it and the PMO owns the file. Note that
+  `grep -n "parse_tracks(" bin/*` is now **2** lines against the KR's baseline
+  of 4-plus-definition, so the KR's own instrument reads clean on this row
+  regardless of the wording dispute. I did not re-count the literal residue and
+  I did not edit the phase file.
+
+---
+
+## `unittest discover -s tests`
+
+
+The RESULT declines to measure this runner (*"I did not re-measure that and do
+not report a number for it"*), while the original spec's criterion 4 —
+which the amendment says still holds — asks for it. **I measured it**, serial,
+~33 minutes each, on the same two clean `git archive` copies:
+
+| tree | runner | tests | failures |
+|---|---|---|---|
+| `base-6c0d041/` | `python3 -m unittest discover -s tests` | 2882 | 6 |
+| `head-a917a43/` | `python3 -m unittest discover -s tests` | 2902 | 6 |
+
+`diff` of the sorted failure lines: **empty — the identical set.** The three
+extra over `bash tests/run` are exactly the artifact the amendment predicted:
+
+```
+test_risks_store.TestTheReadersAreOneFunction.test_the_bullet_and_placeholder_rules_are_one_object
+test_risks_store.TestTheReadersAreOneFunction.test_the_columns_are_one_list
+test_risks_store.TestTheReadersAreOneFunction.test_the_register_header_predicate_is_one_object
+```
+
+All three are pre-existing at `6c0d041` and untouched by this branch. Criterion
+4 is satisfied in the sense that matters: **this change adds no failure under
+either runner.**
+
+---
+
+## What I checked
+
+- Read `bin/perry-state`'s whole track section, `bin/perry-lint §
+  check_md_store_drift`, `perry_md_store.plan` and `record_key`, and the four
+  call sites, before running anything.
+- Rebuilt the amendment's two-store comparison, state 7, W1/W2/W3, the
+  localized path, an order-drift case and a setting-drift case **from my own
+  fixtures**, not the author's helpers, on both trees.
+- 17 mutations in a third copy, own harness, anchor-asserted, md5-verified.
+- All 27 anchors the RESULT names, printed and matched.
+- `bash tests/run` and `unittest discover -s tests` on both trees, full logs.
+- The four known green-for-the-wrong-reason modes on this project: the ADR-004
+  gate is opted out via `tests/gate.py § GATE_OFF` in the fixture's
+  `.perry/config.md` (and my own probes wrote successfully through it, so it is
+  not refusing before the code under test); `TestTheInstrumentWorks` and
+  `test_the_two_stores_really_do_differ` are real controls proving the fixtures
+  are not degenerate; no new test greps its own source; the `reference/diagnose.md`
+  row landed under `## Finding catalog` between `MODE-01` and `FIT-01`; the
+  retired-predicate test calls each stub with **its own** arity so the
+  `TypeError` comes from the body, not from argument counting.
+
+## What I did NOT check
+
+- **Whether the three (six) pre-existing failures are real defects.** Out of
+  scope; identical on both trees.
+- **The `records_out_of_stored_order` and `cells_wearing_decoration`
+  exclusions beyond one fixture each.** I measured the behaviour; I did not
+  enumerate every shape that reaches them.
+- **Any language other than `en` and `zh`.**
+- **`viewer/` readers, `perry-conform`'s `Conformance gate` read, Windows
+  paths, multi-repo layouts** where the state root is not the project root.
+- **The `perry-diagnose` execute stage, `adopt`, `relocate`** — and no
+  write-side tool was run against the reviewed worktree or
+  `/Users/bytedance/proj/Perry`.
+- **The 11 mutations of the RESULT's 28 I did not re-run** (M3, M3c, M13+M14,
+  M17, M18, C3a, C3b, C3c, M20, M21, and the individual M13/M14 greens). Their
+  anchors all match; I sampled 17 and every sample was exact, so I extend
+  provisional credit to the rest rather than claiming to have verified them.
+- **`P003-O2-KR1`'s literal residue count.** Not re-counted, as with rounds 4
+  and 5, which disagreed about it.
+
+---
+
+## Verdict
+
+```
+=== VERDICT ===
+task: TASK-095
+rung: V4
+result: PASS
+criteria: perry/evidence/2026-08/TASK-095-spec.md § Amendment 2026-08-29 — USER-905
+proof: Principle A is computed once and by the thing that owns it —
+  bin/perry-state § tracks_the_register_contradicts calls perry_md_store.plan,
+  the same call bin/perry-lint § check_md_store_drift makes, and reads
+  cells_the_store_and_the_file_disagree_on + lines_verbatim(kind=track) out of
+  its report; nothing is re-derived. Reconstructed the amendment's own case
+  independently — one table main/queue/standing/4/3d/V2 against two stores
+  differing only in whether a contradicting `main` record exists — and at
+  a917a43 perry-lint, perry-state, perry-task, perry-goals and perry-diagnose
+  give the IDENTICAL verdict on both (lint ['track/main'], 1 payload warning,
+  add rc=0 drift-warned, goals rc=1 drift-warned for the commitments gate on
+  both, MODE-02 true), where 6c0d041 gave opposite responses. Refusal reverted
+  to store-default: W1/W2/W3 go add exit=1 -> exit=0 with a stderr warning,
+  each verified by command on both trees, and W3's named remedy still exits 1,
+  pinned by test_the_named_remedy_really_does_fail_on_W3 which I proved is a
+  pin by simulating the fix (perry_md_store.py:960 losses=[] -> that one test
+  and only it goes RED). Decision 3 satisfied: perry-goals:2169 `if lost:` ->
+  `if False:` is 1 RED (test_goals_refuses_when_a_declared_track_has_no_row_at_all)
+  where round 5 measured the full suite at baseline. perry-diagnose made
+  consistent: MODE-02 + tracks_contradicted, state 7 now ['intake','main'] on
+  all four readers. M11 (round 4's literal at perry-state:1058) is a genuine

+  discover -s tests, which the RESULT declined to measure: 2882/6 and 2902/6,
+  identical set, the 3 extra being the pre-existing test_risks_store
+  double-import artifact. New stderr warning ruled IN SCOPE and measured to
+  widen nothing: three previously-clean workflows are byte-identical between

+  deletion. bin/perry-state:1022 `if k.startswith("track/") and "/" in k}` ->
+  `if "/" in k}` leaves all 56 tests GREEN, and it is NOT an equivalent
+  mutant: cells_the_store_and_the_file_disagree_on is not filtered by kind, so
+  on a table whose track row agrees and one hand-edited `- Last updated:`
+  setting, tracks_the_register_contradicts returns ['last_updated'] and
+  perry-task prints "the track register disagrees ... on last_updated". The
+  shipped code is correct; the line is missing from the RESULT's "every other
+  guard this change touches" table and needs one test.

+
+## Amendment 2026-08-29 — USER-905. This section binds.
+
+Five rounds failed V4, three of them regressions the PMO introduced, and every
+one the same shape: two situations answered as one, a step to the left of the
+last. Round 1 collapsed four `None` returns. Round 2 collapsed `no-track-record`
+into unusable and hard-blocked three of this repo's own fixtures. Round 3
+collapsed the two default cases. Round 4 filtered on the NAME `main` instead of
+on whether the table DECLARED it. Round 5 compares names over records.
+
+The user answered USER-905. Where this amendment and the original disagree, this
+wins.
+
+### Decision 1 — the principle: **A**
+
+**A declared row the register contradicts is drift.** One principle, applied
+everywhere, with no second principle for the synthesised `main`.
+
+Consequences that must hold:
+
+- A table declaring `queue/4/3d` beside a store recording `project` **warns**.
+- `perry-lint` already computes exactly that rule. Do not re-derive it on the
+  write side — the root cause across three rounds was deriving it differently
+  each time. Route to the one that owns it.
+- `tracks_missing_from_the_register` compares a set of **NAMES** (`have`), so a
+  record that *contradicts* a declared row counts as carrying it. It must compare
+  **records**. One table (`main/queue/standing/4/3d/V2`) against two stores that
+  differ only in whether a `main` record exists currently gives opposite
+  responses while `perry-lint` reports the same rule on the same row in both.
+- Resolve the file's self-contradiction: `stored_tracks`' docstring and
+  `TRACKS_ANSWERED` both say `store-default` means the store **answered**, and
+  `have`, forty lines later, says that same `main` did not.
+
+**Option B is rejected** — "the store is truth and the table is a stale
+projection". It was defensible, and it is not what was chosen.
+
+### Decision 2 — the refusal width: revert to round 4's
+
+**Revert the write refusal from `source=store` to round 4's
+`source=store-default`.** This is urgent and it is a regression the PMO caused.
+
+Measured by the round 5 reviewer: widening it hard-blocks three ordinary
+hand-edit workflows that wrote successfully at `45a355d` and at round 4. On the
+third — derive the store from a two-track table, then hand-swap one row —
+`perry-config write --from-file`, the **only** command either refusal message
+names, exits 1. The block cannot be cleared by the documented remedy.
+
+**Do not widen again** until `perry-config write --from-file` is fixed. That is a
+separate filed row (it writes a zero-record store at exit 0 on a `config.md` with
+no settings, and is then both the cause and the only offered recovery). A
+refusal whose named remedy fails is worse than no refusal.
+
+### Decision 3 — the `perry-goals` half is a tautology
+
+Deleting it leaves the full 2882-test suite at exactly the baseline. Give it a
+test that actually fails when the guard is removed, or delete the guard. Do not
+ship it as it stands — that is the same defect `TestTheGoalsLaneRefusesToo`'s own
+docstring records against round 2.
+
+### Where round 6 starts
+
+**From `main` at 70eae67**, which now carries rounds 2 through 5 (merged
+2026-08-29 in `777d021`). The writer was measured on this repository's data
+before that merge and does **not** refuse here — this project's config store and
+its `## Tracks` table agree — so the regression is on `main` but not reachable
+on `main`'s own state. Round 6 removes it rather than working around it.
+
+### Verification — V4, amended
+
+Items 1 through N of the original still hold, plus:
+
+6. The principle is applied ONCE. Show the same table against two stores
+   differing only in a contradicting record, and show `perry-lint`, the writer
+   and `perry-goals` all give the same verdict on both.
+7. The trackless case, the store-default case and the contradicted-declaration
+   case are each named, each tested, and each consistent with principle A.
+8. The three hand-edit workflows the round 5 reviewer measured as blocked are
+   shown WORKING again, by command, with exit codes.
+9. `perry-diagnose` is the fourth converted reader and currently carries
+   `tracks_source` with **no** drift signal — on state 7 it reports
+   `store-default/['main']` with empty stderr while the other three warn. Either
+   make it consistent or record in the RESULT why it is exempt.
+10. Baselines name both the runner and the tree. `main` at 70eae67 is 98 modules
+    / 2882 tests / 3 failures under `bash tests/run`; `unittest discover` shows
+    3 more from a module-double-import artifact in `test_risks_store`.

+## Summary
+
+- **17** row(s) said nothing the register does not.
+- **7** row(s) carried at least one word the register does not. Each cell is quoted in full below, because a summary of deleted prose is not the prose.
+
+### `P001-O1-KR3`
+
+- **KR text cell**: Switching a track's mode edits one file and rewrites no state, shown by a revert test (baseline: unproven)
+- **Metric / Target cell**: 1 file · 0 rewrites
+- **Linked overall KR cell**: KR-O1.3 — carried across into the register's new `linked` field
+
+### `P001-O3-KR1`
+
+- **KR text cell**: A state file can declare it is Perry-shaped, at a version, and every writer gates on that declaration (baseline: `is_adopted()` answers only "is there any Perry file here")
+- **Metric / Target cell**: 1 marker, all 3 writers gating
+- **Linked overall KR cell**: KR-O3.4 — carried across into the register's new `linked` field
+
+### `P002-O1-KR3`
+
+- **KR text cell**: A hand edit to a rendered file is reported rather than honoured, at the severity the user picks (baseline: it is honoured)
+- **Metric / Target cell**: reported
+- **Linked overall KR cell**: — — carried across into the register's new `linked` field
+
+### `P003-O1-KR1`
+
+- **KR text cell**: Stores declared in `claims[]` that exist on disk (baseline 4 of 6 — `intake.jsonl` and `asks.jsonl` were built by TASK-196 / TASK-197 and never imported)
+- **Metric / Target cell**: 6 of 6
+- **Linked overall KR cell**: KR-O2.1 — carried across into the register's new `linked` field
+
+### `P003-O2-KR2`
+
+- **KR text cell**: The adoption/migration reader is fenced into one named module, with a mechanical guard that fails when a non-adoption call site parses a projected file — and the guard is shown able to go red by restoring one removed call site (baseline: no boundary; `viewer/parsers.py` is 3,973 lines serving both roles)
+- **Metric / Target cell**: guard live · reverting one call site turns it red
+- **Linked overall KR cell**: KR-O2.3 — carried across into the register's new `linked` field
+
+### `P003-O2-KR3`
+
+- **KR text cell**: `BOARD.md`'s two truth models are marked in the file, so a reader can tell which sections are projected from a store and which are still canonical markdown (baseline: nothing marks the boundary — TASK-199)
+- **Metric / Target cell**: boundary marked
+- **Linked overall KR cell**: KR-O2.1 — carried across into the register's new `linked` field
+
+### `P003-O3-KR1`
+
+- **KR text cell**: Open `main`-track rows in neither `objectives[].krs[].tasks[]` nor a declared `unlinked[]` — the never-asked state (baseline 45 of 45 at phase start, measured by `perry-state --section attribution` on 2026-08-28; the 5 carry-over edges declared with this file are the first movement)
+- **Metric / Target cell**: 0
+- **Linked overall KR cell**: KR-O2.3 — carried across into the register's new `linked` field
+
+## What was NOT done
+
+**Nothing above was merged into the register.** Rewording a KR is a `goals`-lane
+write and this row is not one: TASK-157 removes the second copy, it does not
+adjudicate which copy was right. Where a phrase above matters, the register is
+the file to edit, and the `goals` lane owns that edit.
+
+`Linked overall KR` is the one column that WAS carried across verbatim, into
+the register's new optional `linked` field. It is the only one of the table's
+four columns the register had no field for, so deleting the table without it
+would have deleted a fact rather than a duplicate.

+

+> **One substantive defect was found and fixed** rather than merely noted: the
+> body's claim that the `Linked overall KR` column was carried into the
+> register was false for all eight of phase 001's KRs. See the audit.
+
+## The option taken, and why
+
+**Option (b).** The phase document stops carrying a KR table at all, and
+`bin/perry-goals krs` prints one from `phase/<NNN>-linkage.md`.
+
+The dispatch opened with option (a) — generate the table from the register and
+report hand edits to it as drift — and forbade (b) on the ground that it would
+pre-empt DESIGN-013. That was superseded mid-task by the coordinator, and the
+claim was checked against the repository rather than taken on the message's
+word: `perry/design/DESIGN-013-one-place-per-fact.md` is on `main` at
+`8abd30d`, `Status: locked`, and its User Decision 1 reads **adopt as stated**:
+
+> A fact that has a schema lives in exactly one store. A document holds what
+> has no schema. No field lives in both.
+
+A phase KR's `id`, `title`, `metric`, `target` and linked overall KR are all
+schema'd — `schema/state-schema.json`, `files[id=linkage].frontmatter` and the
+phase file's own `tables[]` entry. Under the adopted rule they live in the
+register and nowhere else. Option (a) would have built a second copy plus a
+reconcile for it, which is the thing the rule names.
+
+Work already done under (a) was discarded, not shipped alongside: a
+`bin/perry_phase_krs.py` that rendered the table from the register through
+`perry_store`'s cell model and reported per-cell drift was written and deleted.
+Its measurement survives and is what makes the case: run against the tree at
+`30cc467`, **all 24 KR rows across phases 001, 002 and 003 disagreed with their
+register** — 22 on the `Metric / Target` column alone, because the two copies
+had been edited apart for a year of phases. A reconcile shipped on that tree
+would have reported 24 rows of drift on day one.
+
+> **[corrected]** Re-measured independently at the fork point `8abd30d` by a
+> read-only scanner that pairs each declaration row with its register entry and
+> normalises away backticks, bold and whitespace: **24 of 24 rows disagree, and
+> the count on the `Metric / Target` column is 24, not 22.** Both agree that
+> every row disagreed; the second measurement is the stricter one. Rows under
+> `## Retro` were excluded from both — those are the score table, not a
+> declaration. The direction of the finding is unchanged and stronger.
+
+DESIGN-013 § 1.2 and § 3 both put the `phase/` pair explicitly **out of scope**
+of that design and name TASK-157 as its owner. So this row is not implementing
+DESIGN-013; it is the first row to apply its rule. Nothing here touches
+`OKR.md`, `BOARD.md` or `DECISIONS.md`.
+
+## The single declaration
+
+`phase/<NNN>-linkage.md`, YAML frontmatter, `objectives[].krs[]`. It already had
+the only writer (`bin/perry-goals link`), the only machine reader
+(`viewer/parsers.py § parse_linkage`) and a spec version. It gained one field:
+
+- **`linked`** — the overall KR this phase KR serves, i.e. the `Linked overall
+  KR` column. It is the one column of the four the register had no field for, so
+  deleting the table without it would have deleted a fact rather than a
+  duplicate. **Additive and optional**, so `linkage: 1` is unchanged: a register
+  written before it reads as an empty cell always did, and that is asserted
+  (`TestTheLinkedOverallKrCameWithIt.test_a_register_without_it_is_not_an_error`).
+
+`viewer/parsers.py § phase_key_results` is the one resolver. Every reader goes
+through it — `bin/perry-goals` (`kr_rows`, `build`), `bin/perry-state`'s phase
+payload, and `parsers.py`'s own smoke print. The **payload shapes are
+unchanged**; only the source moved.
+
+### The one place a document is still read
+
+A project that has not migrated — an adopted project, or a Perry project older
+than this row — has a phase document with a table and a register with no
+`krs[]`. `phase_key_results` reads the document **exactly then**: one source at
+a time, chosen by "does the register declare anything", never merged. Same
+choice, same reason, in `bin/perry-lint`'s `linkage-kr-exists` loop. The shipped
+instance is `tests/fixtures/sample-project-zh`, which has a phase document and
+no register, and `TestAProjectWithNoRegisterStillReadsItsDocument` asserts both
+that it is still that shape and that its KRs still reach a payload.
+
+## Verification
+
+The dispatch's items 1 and 2 assumed two surfaces. Under (b) there is one, so
+they are restated as the coordinator directed.
+
+**1 — the render prints what the register declares, and no KR table is left.**
+`TestChangingTheRegisterChangesEverySurface` edits one line of a fixture
+register and shows the `krs` render, `perry-goals list --json` and
+`perry-state --json` all follow, with `test_no_second_file_had_to_change`
+asserting the phase document is **byte-identical** across that edit.
+`test_no_phase_document_carries_a_kr_table_row` and
+`test_perry_owns_no_phase_document_with_a_kr_table` sweep the fixture and the
+live tree for a KR declaration table and find none.
+
+The sweep distinguishes a *declaration* table from a table that merely mentions
+KR ids: `phase/001-work-modes-live.md` carries a `| KR | Score | Measured |`
+retro table naming all eight of its KRs, and `phase/001-linkage.md`'s body
+carries an attribution table doing the same. Those are the record of what
+happened to a KR — document work, untouched. Only a table under the header the
+schema declares counts, and the predicate reads that header out of the schema
+(and its i18n glossary, because `sample-project-zh`'s reads `| 编号 | KR 描述 |`)
+rather than retyping it.
+
+**2 — there is no derived surface, so there is no reconcile.** `bin/perry-lint`
+gained no phase-KR drift check and this suite contains none. What is asserted
+instead is that the second copy does not exist: for every KR the register
+declares, the id, the title and the metric each occur in exactly one file under
+`phase/` (`TestTheKrIsWrittenInExactlyOnePlace`). `perry-goals krs` has no
+`--write` and refuses one by name.
+
+**3 — `P003-O2-KR1`, the live regression case.** At the fork commit the phase
+document's `Metric / Target` cell read `0` while its register read
+`0 (baseline 4, all parse_tracks: bin/perry-task:6680, bin/perry-diagnose:1888,
+bin/perry-goals:2102, bin/perry-state:139)`, and nothing compared them. That is
+reproducible from git and is row 4 of the `003-storage-code.md` table in
+`TASK-157-removed-kr-tables.md`. There is now exactly one file under
+`perry/phase/` carrying that metric, asserted as a cardinality rather than a
+filename literal — `test_the_regression_case_carries_its_target_in_one_file`.
+**Its value was not edited.** The number is unchanged in the register; this row
+removed the second copy of it.
+
+**4 — mutation.** **[corrected — none of the run below was verified when it was
+written; it has now been re-run from scratch by a second agent, and one of its
+seven claims did not hold.]**
+
+Fourteen reverts, each anchored by exact text asserted present before it is
+replaced, applied with every `__pycache__` cleared and a sleep past the
+whole-second boundary either side, each file restored and md5-verified, and the
+tree checked clean after. The harness refuses to start on a dirty tree, holds a
+lockfile named after itself, and **asserts the target is GREEN before the
+mutation** — that last check is what caught the first attempt at M3 and M4,
+where `python3 -m unittest tests.test_cadence` reported a red that was an
+import error (`tests/test_cadence.py` does `from gate import GATE_OFF`, which
+resolves only when `tests/` is the discovery start directory). A red that is a
+loader failure says nothing about the mutation. Every run below is
+`python3 -m unittest discover -s tests -p <module>.py`, which is how
+`tests/run` loads them.

+| M14 | the `metric:` placeholder points at the phase file again | `goals/state/linkage_TEMPLATE.md:17` | the same test, reporting the offending line |
+
+**M4 is the one that did not hold, and it is the reason this row was re-run.**
+The inherited table above had no M4 of this kind at all: it listed seven
+mutations and none of them touched the *phase* half of `linkage-kr-exists`.
+`f15d234` replaced that check's document scan with **two** direct questions
+about the KR id — does it name the objective it is declared under, and does it
+name the phase whose register it sits in — and shipped a test for only the
+first. `test_a_genuinely_wrong_kr_is_still_reported` supplies `P001-O9-KR9`,
+whose phase is still `001`, so it fails the objective half and can never reach
+the phase half.
+
+Measured: deleting `if not kr.id.startswith(f"P{own}-")` from `bin/perry-lint`
+and running the **whole** suite left the failure set byte-for-byte identical —
+the same five pre-existing failures, nothing newly red, nothing newly green. A
+guard that can be deleted with the suite unchanged is not a guard, which is the
+standard this repository applied to `perry-goals` on TASK-095. Two tests were
+added at `tests/test_cadence.py`, supplying `P002-O1-KR1` inside
+`001-linkage.md` with the objective kept at `O1` so that only the phase half can
+produce the finding; M4 now reddens both.
+
+**M12 is a defect the mutation run found in the shipped work**, not a mutation
+of a guard. See the audit at the bottom.
+
+**Distrusting green.** The fixture is a copy of `tests/fixtures/sample-project`,
+and `TestTheFixtureIsTheShapeUnderTest` is the control: it asserts the fixture
+has a register, that the register declares **three** KRs and two objectives, and
+that those ids reach `perry-goals list --json`. Without it, "no KR is declared
+twice" and "every surface follows the register" both pass on a fixture that
+parses nothing. `TestAProjectWithNoRegisterStillReadsItsDocument`'s first test
+is the same control for the legacy path.
+
+One assertion was written as a closed literal over live state
+(`assertEqual(carriers, ["003-linkage.md"])`) and
+`tests/test_live_state_expectations.py` caught it. It is now a cardinality plus
+a property, which is what was actually under test.
+
+## `plan-phase` no longer authors the block
+
+The row's original title. Three files:
+
+- `goals/state/phase_TEMPLATE.md` — the two KR tables are gone; each
+  `### Key Results` heading carries a pointer to the register and the command.
+- `goals/reference/phases.md` — step 7 of *The ten mandatory sections* said
+  "write them in a `### Key Results` table" and now says to declare them in the
+  register at *After write* step 2, with the reason. A new `## \`krs\`` section
+  documents the command, including what it will never do.
+- `goals/SKILL.md` — a `krs` row in the subcommand index.
+  `tests/test_claims.py § TestEveryDeclaredSubcommandHasAProcedure` required the
+  reference section before it would accept the row, which is how the section
+  came to exist.
+
+## Baselines
+
+**[corrected — the inherited table shipped with four unsubstituted
+placeholders: `BASELINE_8ABD30D`, `BASELINE_8ABD30D_FAILURES`, `AFTER_RUN`,
+`AFTER_FAILURES`, `AFTER_DISCOVER`, `AFTER_DISCOVER_FAILURES`. Only its first
+row carried real numbers, and that row was measured at `68982cf`, the fork
+point BEFORE the mid-task merge — not at `8abd30d`, which is where this branch
+actually forks from. Every row below was measured by the second agent.]**
+
+| Runner | Tree | Modules · tests | Failures |
+|---|---|---|---|
+| `bash tests/run` | fresh clone at `8abd30d` — the fork point | 98 · 2882 | **5** |
+| `bash tests/run` | `wt-157` at `f15d234` — the inherited restore point | 99 · 2910 | **5** |

+| `bash tests/run` | `wt-157`, branch head — after the V4 template fix | 99 · 2914 | **5** |
+
+The five under `bash tests/run` are **the same five tests on every row**:
+
+1. `test_contract_key_parity.TestAWitnessProjectMakesAnEmptyCollectionObservable.test_without_the_witness_the_four_are_unobservable`
+2. `test_contract_key_parity.TestTheWitnessedKeysRedden.test_the_same_mutation_is_silent_without_the_witness`
+3. `test_diagnose.DecisionsAreCountedPerRecordNotPerMention.test_the_queue_register_reconciles_with_the_queue_on_this_repository` — `2 != 0`
+4. `test_diagnose.TestUserLoadFindings.test_perry_itself_passes_its_own_id_checks` — dangling `['ACTION-7', 'D009-1', 'D010-2', 'PROJ-003', 'SPEC-007']`
+5. `test_kr_progress_provenance.TestBothOfTodaysWrongReadingsFlip.test_no_current_in_the_payload_claims_to_be_a_measurement`
+
+(1) and (2) are **data-dependent, not code-dependent**: they fail whenever
+`conformance.in_progress_with_no_live_run` is non-empty, which is true of any
+board carrying a row left `in_progress` with no dispatch marker for four hours.
+The inherited account's "3 pre-existing failures" is the count on a *different*
+board state at a *different* commit; the honest statement is that the number
+depends on the board, so the tree and the commit have to be named with it —
+which is why every row above names both.
+
+`python3 -m unittest discover -s tests` adds three on both trees:
+`test_risks_store.TestTheReadersAreOneFunction`'s three `test_the_*_is_one_*`.
+That is the module-double-import artefact this repository has between its two
+runners, not a property of this branch. **Both runners are reported because
+they disagree, and a single number without a runner name is not a measurement.**
+
+**This branch adds no failure and removes none.** `python3 bin/perry-lint
+--root perry` on the branch head reports **0 errors**.
+
+## What I did NOT do, and what I could not verify
+
+- **`P003-O2-KR1`'s target was not edited.** It is `0` in the register before
+  and after. The dispatch forbade the edit and it is a `goals`-lane write.
+- **No prose was moved into a register.** Seven of the 24 removed cells carried
+  at least one word the register does not — the two copies had been reworded
+  apart. Each is quoted in full in `TASK-157-removed-kr-tables.md` with the
+  words that differ. Merging them is a `goals`-lane rewording and this row does
+  not adjudicate which copy was right.
+- **`phase/snapshots/` was not touched.** A scored phase's snapshot is the
+  record of what that file said on the day it was scored; rewriting it would
+  make the record disagree with itself (DESIGN-013 § 3, non-goal 1). Those
+  snapshots still carry KR tables, deliberately, and the sweep excludes them by
+  construction rather than by omission.
+- **The schema still declares the phase KR table**, now `"optional": true` with
+  a note. It is the shape an adopted or unmigrated project has, and a table
+  Perry can still meet is a table Perry must still validate. The consequence:
+  `perry-lint` will not report a project that reintroduces a KR table by hand —
+  only `tests/test_phase_kr_declared_once.py` does, and only for this
+  repository's own files and its fixtures. A linter rule for it was not added
+  because on an unmigrated project it would be a false positive on every phase.
+- **`bin/perry-migrate`'s adoption reader was not changed.** It parses a foreign
+  project's phase document, which is what adoption is, and is the exclusion
+  `P003-O2-KR1` already names.
+- **`perry-goals krs` was not run against `/Users/bytedance/proj/Perry`.** It is
+  read-only, but nothing write-side was run there either.
+- **Not verified: how the render reads as the only surface.** DESIGN-013 § 6
+  step 2 asks the `OKR.md` row (TASK-236) to report in writing on whether a CLI
+  render is a good enough read surface, and § 7 makes step 3 conditional on that
+  report. This row did the same move on a smaller file without producing that
+  report, because it was not asked for one. What can be said: the phase KR table
+  was 16% of `003-storage-code.md` with a longest cell of 307 bytes, and
+  `perry-goals krs` renders it through `tables.render_row`, so the output is the
+  same markdown table in the terminal. Whether that is a sufficient substitute
+  for opening the file is a judgement TASK-236 is the row for.
+- **Not verified: any consumer outside this repository.** `perry-state --json`'s
+  `phase.objectives[].krs[]` keeps its key shape and its `contract` string is
+  untouched, so a pinned consumer sees no break — but aiMark was not run against
+  the new tree.
+- **Coordination.** `bin/perry-goals` is also being edited by TASK-095 round 6.
+  This row's changes there are `kr_rows`'s phase source (~line 924), `build`'s
+  `phase_krs` count, the `krs` command block before `COMMANDS`, one `parse()`
+  flag, and one `main()` dispatch branch. Expect a merge, not a conflict of
+  meaning.

+
+## The one thing that was wrong, and is now fixed
+
+**`phase/001-linkage.md`'s eight `linked:` values were copied from the wrong
+table.**
+
+The account above says the `Linked overall KR` column "was NOT dropped with the
+table — that would have deleted a fact rather than de-duplicated one", and
+`TASK-157-removed-kr-tables.md` closes by saying it "WAS carried across
+verbatim". For phases 002 and 003 that is true. For phase 001 it is the
+opposite of what happened: all eight `linked:` values were taken from the
+**retro score table** — `| KR | Score | Measured |` at
+`001-work-modes-live.md:232` — so `P001-O1-KR1`'s edge to `KR-O1.1` was written
+as
+
+```yaml
+linked: "`parse_tracks` on `.perry/config.md` returns `[('main','project')]` — 0 of 3 non-`project` modes on a live track"
+```
+
+which is a sentence that already lived in the document. Eight edges from phase
+001's KRs to the overall OKR — `KR-O1.1`, `KR-O1.2`, `KR-O1.3`, `KR-O2.1`,
+`KR-O3.4` — were deleted along with the table they were supposed to be rescued
+from, and a ninth copy of prose was gained in their place.
+
+**This is the row's own failure mode, committed by the row.** A fact was written
+in two places, one copy was deleted, and nothing checked that what replaced it
+was the same fact. It is also why "a KR is declared once" needs a guard on the
+field and not only on the file.
+
+Measured against the phase documents as they stood at `8abd30d`: at `f15d234`,
+**16 of the 24 `Linked overall KR` cells survived the move and 8 did not.** At
+the branch head, **24 of 24 do.** Phase 002's column was `—` throughout, so
+nothing was there to lose; phase 003's eight were transcribed correctly.
+
+Fixed at `3784059`, together with the guard that would have caught it:
+`TestTheLinkedOverallKrCameWithIt.test_every_linked_value_names_an_overall_kr_this_project_declares`
+reads every `phase/*-linkage.md` in the live tree and requires each non-empty
+`linked` to **resolve** against `perry-goals list --level overall`. Resolve
+rather than match a shape, because `KR-O9.9` has the right shape and is a
+dangling reference. It also refuses to pass when no register carries a `linked`
+value at all, so it cannot quietly go vacuous. Mutation M12 puts the corrupt
+value back and it goes red.
+
+No KR's id, title, metric or target was touched by the fix. `P003-O2-KR1` is
+byte-identical to its value at `8abd30d`.
+
+## Claim by claim
+
+| The inherited account claims | Verdict |
+|---|---|
+| Option (b) was taken: the phase document carries no KR table, the register is the single declaration, `perry-goals krs` renders it | **Confirmed.** No `phase/<NNN>-<slug>.md` under `perry/` carries a KR declaration table; `perry-goals krs` prints one from the register. |
+| The suite passes | **Confirmed, and now measured for the first time.** `bash tests/run`: 5 failures at the fork point, the same 5 on the branch. `discover`: 8 and 8. Both runners named, both trees named. |
+| Baseline table | **Corrected.** It shipped with six unsubstituted placeholders and its one real row was measured at the wrong commit. Replaced with five measured rows. |
+| All 24 KR rows disagreed with their register; 22 on `Metric / Target` | **Confirmed on the count of rows, corrected on the column.** Independently measured at `8abd30d`: 24 of 24 disagree, and the `Metric / Target` count is 24, not 22. |
+| `P003-O2-KR1`'s value was not edited | **Confirmed.** `git diff 8abd30d..HEAD -- perry/phase/003-linkage.md` shows the register's only change is the additive `linked:` line; `target: 0` and the `metric:` string are byte-identical. |
+| There is now exactly one file under `perry/phase/` carrying that metric | **Confirmed** by running it: `003-linkage.md`, and nothing else. |
+| Seven mutations, each reddening a named test | **Six confirmed, one absent, and the absent one matters.** The phase half of `linkage-kr-exists` was never mutated and was covered by nothing — deleting it left the whole suite unchanged. Fixed at `09dcdff`. The re-run is twelve mutations, all reddening named tests. |
+| `perry-goals krs` is read-only and refuses a `--write` | **Confirmed.** `krs --write` and `krs foo` both refuse and exit 1; `krs --phase 099` refuses and exits 1; `krs --phase 002` reads a scored phase and exits 0. |
+| `plan-phase` no longer authors the block | **Confirmed** in all three files: `goals/state/phase_TEMPLATE.md` carries no KR table (M7 holds it), `goals/reference/phases.md` step 7 now points at the register and gained a `## krs` section, `goals/SKILL.md` carries the row. |
+| A project with no register still reads its document; the shipped instance is `sample-project-zh` | **Confirmed.** `tests/fixtures/sample-project-zh/phase/` holds `001-release-pipeline.md` and `CURRENT` and no `*-linkage.md`. M10 and M11 hold both halves of the fallback — one in `viewer/parsers.py`, one in `bin/perry-lint`. |
+| The `linked` field is additive and optional, so `linkage: 1` is unchanged | **Confirmed.** A register with every `linked:` stripped still parses and publishes `""`, and M5 holds it. |
+| `tests/test_live_state_expectations.py` caught a closed literal over live state during the first agent's run | **Not checkable.** It describes something that happened inside a session that no longer exists. The assertion as it stands today is a cardinality plus a property, which is what the account says it became. |
+| `perry-lint` will not report a project that reintroduces a KR table by hand | **Confirmed, and it is a real limitation.** The sweep lives only in `tests/test_phase_kr_declared_once.py` and covers this repository and its fixtures. The stated reason — a lint rule would false-positive on every unmigrated project — holds. |
+| No consumer outside this repository was checked; aiMark was not run | **Confirmed as still true.** Not run here either. `perry-state --json`'s `phase.objectives[].krs[]` key shape is unchanged by inspection, which is not the same as a consumer having read it. |
+| `bin/perry-migrate`'s adoption reader was not changed; `phase/snapshots/` was not touched | **Confirmed** from the diff — neither appears in it. |
+
+## The V4 finding, and what the guard does not prove
+
+The V4 review passed the row and left one non-blocking finding, closed here.
+
+**`goals/state/linkage_TEMPLATE.md` had not been updated with the rest of
+`plan-phase`.** The KR table's removal made the register the only place four of
+a KR's five fields can come from, and the template an author writes that
+register from had **no `linked:` slot at all**, plus a `metric:` placeholder
+reading *"metric as written in the phase file"* — pointing the next author at a
+file that no longer holds it. A phase 004 authored from it would have had every
+`linked` empty: the same lost edge this row already had to repair once in
+`phase/001-linkage.md`, displaced into the future. The template now offers a
+`linked:` slot on every KR stub with a comment saying what belongs in it and
+what went wrong last time, its `metric:` placeholder names the register, the
+key table documents `linked`, and the rules list carries the sentence that
+`linked` must resolve to an overall KR `OKR.md` declares.
+`goals/reference/linkage.md` described `perry-lint` as checking "every KR id
+present in the phase file", which stopped being true at `f15d234`; it now
+describes the two id checks that replaced it.
+`test_the_register_template_offers_every_field_a_kr_now_has` holds the template
+edit, and `perry-lint --templates` — the schema drift guard — stays clean.
+
+**The limitation the guard has, stated rather than fixed.**
+`test_every_linked_value_names_an_overall_kr_this_project_declares` requires at
+least 8 `linked` values across all of `perry/phase/*-linkage.md` before it will
+accept a pass. Phases 001 and 003 already satisfy that between them. So the
+guard proves that **some** phase has resolvable edges to the overall OKR — it
+does not prove that **this** phase, or the newest one, does. A phase 004
+written with every `linked` empty would leave it green. Widening it is a scope
+decision rather than a template fix and is deliberately not taken in this row;
+the coordinator is filing it as its own row.
+
+## What this round did not check
+
+- **`perry-goals krs` as a read surface.** DESIGN-013 § 6 step 2 asks TASK-236
+  to report on whether a CLI render is a good enough substitute for opening the
+  file. That report does not exist and this row did not write one. The output
+  is the same markdown table in the terminal; whether that is enough is a
+  judgement, not a measurement.
+- **Any consumer outside this repository.** aiMark was not run, by this round
+  or by the V4 reviewer. `perry-state --json` keeps its key shape and its
+  `kr_total`, and the `contract` string is untouched — but `metric` now carries
+  the **register's** wording, which is longer than the phase document's cell
+  was on 22 of 24 KRs. A pinned consumer sees no structural break; whether it
+  renders a longer string acceptably is unmeasured.
+- **The three `test_risks_store` failures under `discover`.** Taken as the known
+  double-import artefact on the strength of their being identical on both trees,
+  not diagnosed.
+- **Whether the two `test_contract_key_parity` witness failures clear on a
+  quiet board.** They were identical on the fork point and on the branch, which
+  is what rules them out as this row's doing; no board was cleaned to watch
+  them go green.

+## Trees under test
+
+| Name | What it is |
+|---|---|
+| `base-8abd30d` | a fresh `git clone` of the repository, `git checkout 8abd30d` — the fork point, the commit `coding/task-157-kr-declared-once` branches from. Untouched by this work. |
+| `wt-157` | the worktree, branch `coding/task-157-kr-declared-once`, at `f15d234`. |
+
+Both trees carry **committed** board state, so the two are compared on the same
+kind of input. Neither is `/Users/bytedance/proj/Perry`, whose working tree is
+dirty and whose numbers would not be reproducible.

+5. `test_kr_progress_provenance.TestBothOfTodaysWrongReadingsFlip.test_no_current_in_the_payload_claims_to_be_a_measurement`
+
+(1) and (2) are the data-dependent witness pair: they fail whenever
+`conformance.in_progress_with_no_live_run` is non-empty, which is true of any
+board carrying a row left `in_progress` with no dispatch marker for four hours.
+They are a property of the board state both trees carry, not of this branch.
+
+`python3 -m unittest discover -s tests` adds three on **both** trees'
+shape — `test_risks_store.TestTheReadersAreOneFunction`'s three
+`test_the_*_is_one_*` — which is the module-double-import artefact this
+repository is known to have between the two runners. Naming the runner is
+therefore load-bearing and both are reported.
+
+**This branch adds no failure and removes none.** The new module
+`tests/test_phase_kr_declared_once.py` contributes 27 tests, all green.
+
+## The duplication, measured at the fork point
+
+A read-only scanner over `base-8abd30d` (scratchpad, not committed) pairs every
+KR *declaration* row in `perry/phase/<NNN>-<slug>.md` with the same id in
+`perry/phase/<NNN>-linkage.md` and compares the cells, normalising away
+backticks, bold and whitespace. Score-table rows under `## Retro` are excluded:
+those record what happened to a KR and are not a second declaration of it.
+
+```
+declaration rows found in phase documents:   24
+rows agreeing with their register on every column:   0
+rows disagreeing:                            24
+  · title column disagreements:              24
+  · metric/target column disagreements:      24
+```
+
+**24 of 24 disagree, on both the title and the metric/target column.** The two
+copies were edited apart over three phases. Anything that had generated the
+table from the register — option (a) — would have reported 24 rows of drift on
+the day it shipped.
+
+## `P003-O2-KR1`, the live regression case
+
+At `8abd30d`, `grep -c` over `perry/phase/` finds the KR's target written in
+**two** files:
+
+- `perry/phase/003-storage-code.md:139` — `| P003-O2-KR1 | … | 0 | KR-O2.1 |`
+- `perry/phase/003-linkage.md` — `target: 0`, `metric: "0 (baseline 4, all …)"`
+
+Both say `0`; the board's filed finding is that `0` is wrong, the literal count
+being >= 7. **That is the point of the row and not its fix.** The defect this
+row closes is that correcting the number takes two edits in two files with
+nothing checking that both happened — and the two cells had already been
+reworded apart (the document's cell reads `0`, the register's reads
+`0 (baseline 4, all parse_tracks: …)`).
+
+At `f15d234` the phase document declares no KR at all, so there is exactly one

+# TASK-157 — the same KR is written twice, in two files, with no check between them
+
+> Investigation completed 2026-08-29 at 30cc467. The row arrived from intake
+> carrying a title and nothing else; this file is the investigation
+> `work/reference/subcommands.md:708` requires before a P1 row is dispatched.
+
+## What was measured
+
+A phase declares its KRs in **two** files under `perry/phase/`, and the id,
+title, metric and target appear in full in both.
+
+`perry/phase/003-storage-code.md:122` — a markdown table row:
+
+```
+| P003-O1-KR1 | Stores declared in `claims[]` that exist on disk (baseline 4 of 6
+— `intake.jsonl` and `asks.jsonl` were built by TASK-196 / TASK-197 and never
+imported) | 6 of 6 | KR-O2.1 |
+```
+
+`perry/phase/003-linkage.md` — YAML frontmatter, spec version 1:
+
+```yaml
+- id: P003-O1-KR1
+  title: "Stores declared in `claims[]` that exist on disk"
+  metric: "6 of 6 (baseline 4 of 6 — `intake.jsonl` and `asks.jsonl` built by
+           TASK-196 / TASK-197 and never imported)"
+  target: 6
+  stretch: false
+  tasks: ["TASK-203"]
+```
+
+Same four facts, twice, in two files in the same directory.
+
+### Nothing checks them against each other
+
+`bin/perry-lint` reports drift for four stores — tasks, risks, OKR, config —
+and reports **nothing** for this pair. There is no `reconcile` for it anywhere
+in `bin/perry-lint`. Confirmed by grep and by running it: the census names
+`store`, `risks store`, `OKR store` and `config store`, and no phase entry.
+
+### The markdown copy is the one that goes stale, and it already has
+
+Filed on the board on 2026-08-29, before this investigation:
+
+> `P003-O2-KR1` still reads target 0 in `phase/003-storage-code.md` while the
+> literal count is >=7 (six `kind:setting` reads at `perry-state:126-135` plus
+> `perry-conform:304`) — the honest number is "0 track-register readings" and it
+> must become an EDIT to the phase file; two reviewers have now said so.
+
+That is the failure this row exists to prevent, already realised, on the phase
+that is running right now.
+
+### Which file each writer touches
+
+- `bin/perry-goals link` writes `phase/<NNN>-linkage.md` in place — the edge,
+  the alias, the declared `unlinked`, the Project. It is the only writer of that
+  file and it refuses anything that does not resolve to exactly one KR.
+- `viewer/parsers.py:3192` reads it — YAML frontmatter, spec version 1.
+- **Nothing writes the markdown KR table.** `plan-phase` authors it by hand, in
+  a file whose own header documents it as machine-written. That is this row's
+  original title and it is one half of the defect; the duplication is the other.
+
+### Shape of the two files
+
+| File | YAML | Prose | Table |
+|---|---|---|---|
+| `phase/001-linkage.md` | 6318 B | 5385 B (46%) | — |
+| `phase/002-linkage.md` | 3272 B | 1647 B (33%) | — |
+| `phase/003-linkage.md` | 3573 B | 1344 B (27%) | — |
+| `phase/003-storage-code.md` | — | 84% | 16% (11 rows, longest cell 307 B) |
+
+## Deliverable
+
+**A KR is declared once.** The id, title, metric and target live in exactly one
+place, and whatever else needs to show them renders them from there.
+
+The linkage YAML is the candidate, because it already has the only writer
+(`perry-goals link`), the only reader (`viewer/parsers.py:3192`) and a spec
+version. The phase document keeps what it is actually for — the narrative, the
+exclusions, the reasoning, the DoD — which is 84% of `003-storage-code.md` and
+is not duplicated anywhere.
+
+Concretely, one of these, and the row must state which and why:
+
+- **(a)** The phase document's KR table is generated from the linkage YAML by a
+  command, and hand edits to it are reported as drift the way `BOARD.md`'s are.
+- **(b)** The phase document stops carrying a KR table at all, and `perry-goals`
+  gains a subcommand that prints it. This is the direction the 2026-08-29
+  discussion favours for `OKR.md` and `BOARD.md` and it should not be chosen
+  here in isolation — see DESIGN-013.
+
+Either way `plan-phase` stops authoring the block by hand, which closes this
+row's original title.
+
+## Verification — V4
+
+1. Change a KR's target in the one declared place and show the other surface
+   follows without a second edit.
+2. Change it in the *derived* surface and show the disagreement is **reported** —
+   named file, named KR, named field. Today it is silent.
+3. `P003-O2-KR1`'s stale target is used as the live regression case: reproduce
+   the disagreement that exists today at `30cc467`, then show the fix reports it.
+4. **Mutation**: revert the reconcile and show a NAMED test goes red. A check
+   that can be deleted with the suite unchanged does not count — `perry-goals`
+   shipped exactly such a guard on TASK-095 and it is being removed for it.
+5. `bash tests/run` at the baseline of the commit the work forks from, named by
+   runner and tree.
+
+## Out of scope
+
+- `OKR.md` and `BOARD.md`. Same shape, and deliberately a separate decision —
+  DESIGN-013. This row is the phase pair only, because that pair is the one with
+  **no check at all** and a stale number on the live phase.
+- Editing `P003-O2-KR1`'s target. That is a `goals`-lane write and the number is
+  already filed; this row makes the disagreement visible, it does not resolve it.

+exports into `scratchpad/rv157-jr/` (uniquely prefixed, per the standing
+constraint about fixed-name tooling in the shared scratchpad).
+
+## Both audit claims: CONFIRMED, by my own measurement
+
+### Claim 1 — the phase half of `linkage-kr-exists` shipped with nothing holding it. **CONFIRMED.**
+
+I exported `f15d234` twice, deleted the guard from one copy, and ran the whole
+suite on both.
+
+```
+$ python3 - <<'EOF'   # deletes exactly the 7-line block, asserts the anchor is unique

+$ diff f15-clean.fails f15-mut.fails
+IDENTICAL failure sets
+```
+
+The whole suite is byte-for-byte unchanged by deleting the guard. The claim is
+exactly right, including its wording.
+
+The fix holds. At branch head, the same deletion (green-first asserted OK
+first) reddens the two new tests and nothing else:
+
+```
+### M4 phase-half guard dropped
+  green-first: ['Ran 56 tests in 30.952s'] OK  fails=[]
+  mutated   : ['Ran 56 tests in 27.460s'] FAILED (failures=2)
+     FAIL: test_cadence.TestLinkageBelongsToItsOwnPhase.test_a_kr_belonging_to_another_phase_is_reported
+     FAIL: test_cadence.TestLinkageBelongsToItsOwnPhase.test_the_phase_half_names_the_phase_and_the_id
+  restored md5 68ac6f33… == 68ac6f33… : True
+```
+
+`test_a_genuinely_wrong_kr_is_still_reported` stayed **green** under that
+mutation — which is the direct proof that it cannot reach the phase half. And
+under M3 (objective half deleted) it is the only test that goes red, while the
+two new ones stay green. The two halves are held separately, by disjoint tests.
+The new tests can only fire on the phase half: the fixture's `001-linkage.md`
+declares `P001-O1-KR1` under `- id: O1`, the mutation rewrites only the phase
+segment to `P002`, so `kr_objective_id` still returns `O1 == obj.id` and the
+objective branch is silent.
+
+### Claim 2 — eight KR→overall-OKR edges were deleted and replaced with prose. **CONFIRMED, numbers exact.**
+
+```
+$ grep -n "linked:" tree-f15d234/perry/phase/001-linkage.md
+15: linked: "`parse_tracks` on `.perry/config.md` returns `[('main','project')]` — 0 of 3 …"
+23: linked: "The code ships — `perry-state` carries `stage_counts`, `wip_breaches` …"
+… all eight are verbatim the retro score table's `Measured` column
+   (001-work-modes-live.md:232, `| KR | Score | Measured |`)
+
+$ grep -n "linked:" tree-1e0935b/perry/phase/001-linkage.md
+KR-O1.1, KR-O1.2, KR-O1.3, KR-O1.1, KR-O2.1, KR-O2.1, KR-O3.4, KR-O3.4
+```
+
+That sequence is byte-identical to the `Linked overall KR` column of
+`001-work-modes-live.md` at `8abd30d`. Phase 002's column is `—` on all 8 rows;
+phase 003's 8 were transcribed correctly. So **16 of 24 at `f15d234`, 24 of 24
+at `3784059`** — the audit's arithmetic is right. This was the most important
+thing on the branch: it is a silent deletion of eight graph edges, strictly
+worse than the duplication the row exists to remove, and the inherited RESULT
+asserted the opposite in writing.
+
+**Both halves of the new guard verified, by mutation:**
+
+```
+### M12  linked put back to the retro prose        → FAIL test_every_linked_value_names_an_overall_kr_this_project_declares
+### M12b linked: "KR-O9.9" (right shape, dangling) → FAIL (same test)   ← it RESOLVES, it does not shape-match
+### M5   parse_linkage stops reading `linked`      → FAIL (same test, via the `checked >= 8` refusal) + 2 more
+```
+
+M5 is the zero-value refusal firing: with the field unread, `checked` drops to
+0 and the test refuses to pass vacuously. Both halves are real.
+
+## Claims measured independently
+
+**Option (b) as described — confirmed.** No `phase/<NNN>-<slug>.md` carries a
+KR declaration table; the only survivors of a full-tree grep are
+`tests/fixtures/sample-project-zh` (deliberately the unmigrated fixture, and
+`TestAProjectWithNoRegisterStillReadsItsDocument` asserts it still has one, or
+that class asserts nothing) and `phase/snapshots/` (excluded by construction).
+The render and all three refusals, run on an exported head:
+
+```
+$ python3 bin/perry-goals krs --root .            → the four-column table, exit 0
+$ python3 bin/perry-goals krs --write --root .    → refused …  exit 1
+$ python3 bin/perry-goals krs foo   --root .      → refused …  exit 1
+$ python3 bin/perry-goals krs --phase 099 --root . → refused — no linkage register at phase/099-linkage.md, exit 1
+$ python3 bin/perry-goals krs --phase 001 --root . → the scored phase's table, exit 0
+```
+
+`plan-phase` no longer authors the block: `goals/state/phase_TEMPLATE.md` (both
+tables replaced by a pointer), `goals/reference/phases.md` step 7 and *After
+write* step 2, and the `krs` row in `goals/SKILL.md`. All three checked, and
+M7 (a table re-appended to the template) reddens
+`test_the_template_carries_no_kr_table`.
+
+**The regression case — confirmed.** `git diff 8abd30d..HEAD --
+perry/phase/003-linkage.md` is eight additive `linked:` lines and nothing else.
+`P003-O2-KR1` keeps `target: 0` and its `metric:` string unchanged. On `main`
+the metric is in two files; on the branch, one — asserted as a cardinality plus
+a property rather than a filename literal, which is the right shape for a
+live-state assertion.
+
+**The duplication at the fork point — re-measured independently.** My own
+scanner over the `8abd30d` export, pairing each declaration row with its
+register entry and normalising backticks/bold/whitespace:
+
+```
+declaration rows: 24
+title cell differs : 24
+metric cell differs: 24
+both differ: 24
+```
+
+24 of 24, not the spec's 22. The branch's number is the correct one. Note the
+sense of "disagree": textual non-identity, and in most rows it is the register
+that says *more* (the baseline moved from the title cell into `metric`). The
+companion `TASK-157-removed-kr-tables.md` measures the other direction — 7 of
+24 cells carried a word the register does not — and both statements are true of
+the same data. The evidence file names its method; a reader who reads only the
+"24 of 24" line will over-read it.
+
+**Twelve mutations — I re-ran all twelve, not five.** Harness: green-first
+asserted before every mutation, `__pycache__` cleared each run,
+`discover -s tests -p <module>.py` as the runner, file restored and md5-compared
+after. Every one was green first and every restore matched. `diff -r` of the
+mutation box against the pristine head export: no differences.
+

+| M12 | `001-linkage.md` `linked` back to prose | `test_every_linked_value_names_an_overall_kr_…` |
+
+**Every guard on this branch survives its own deletion.** That is the defect
+this branch's own audit found in its predecessor, and it is not repeated here.
+
+**The green-first check is real and it matters.** Reproduced:
+
+```
+$ python3 -m unittest tests.test_cadence
+ModuleNotFoundError: No module named 'gate'      (tests/test_cadence.py:30)
+Ran 1 test … FAILED (errors=1)
+```
+
+One `_FailedTest`, indistinguishable from a mutation working if you only read
+the exit code. Asserting the target GREEN before mutating is what makes the
+table above mean anything; this is a better harness than the previous rounds.
+
+**Baselines — reproduced exactly.** Runner `bash tests/run` (which is
+`tests/parallel`, 8 workers). Trees are `git archive` exports of the named
+commits into scratch, so each carries that commit's committed board state.
+
+| Runner | Tree | Modules · tests | Failures |
+|---|---|---|---|
+| `bash tests/run` | export of `8abd30d` | 98 · 2882 | 5 |
+| `bash tests/run` | export of `f15d234` | 99 · 2910 | 5 |
+| `bash tests/run` | export of `1e0935b` (head) | 99 · 2913 | 5 |
+
+The same five tests on every row, `FAIL:` line for `FAIL:` line: the two
+`test_contract_key_parity` witness tests, `test_diagnose`'s queue-register
+reconcile (`2 != 0`) and `test_perry_itself_passes_its_own_id_checks`, and
+`test_kr_progress_provenance`'s. The branch adds no failure and removes none.
+`python3 bin/perry-lint --root perry` on the head export: **0 errors**, 5
+pre-existing warnings.
+
+`python3 -m unittest discover -s tests` on the head export: **Ran 2913 tests …
+FAILED (failures=8, skipped=4)** — the same five, plus exactly the three
+`test_risks_store.TestTheReadersAreOneFunction` tests. That module alone under
+`discover -s tests -p test_risks_store.py` is green (53 tests, OK), which is the
+double-import artefact the branch names, not a regression. Both runners
+reproduce their claimed numbers.
+
+`test_board_render.test_every_rendered_field_moves_when_the_store_moves` did not
+fire on any of my runs.
+
+**The inherited RESULT's errors — confirmed corrected.** `f15d234`'s RESULT
+carries live `BASELINE_8ABD30D` / `AFTER_RUN` placeholders at lines 163–164; the
+head RESULT carries none outside the audit paragraph that names them as the
+defect. Five measured baseline rows, each naming runner and tree. "3
+pre-existing failures" is corrected to 5 with the data-dependence explained,
+"22 rows" to 24. The document separates inherited from measured throughout, and
+its `What I did NOT do` section is unusually honest — it names the schema
+consequence, the untested consumer, and the missing TASK-236 report without
+being asked.
+
+## Findings — none blocking, one worth a row
+
+1. **`goals/state/linkage_TEMPLATE.md` was not updated with the rest of
+   `plan-phase`.** It has no `linked:` slot, and its metric placeholder still
+   reads `metric: "{{metric as written in the phase file}}"` — pointing the
+   next phase author at a file that no longer holds the metric. Consequence:
+   the next register can be authored with every `linked` empty, and nothing
+   catches it — `test_every_linked_value_names_an_overall_kr_this_project_declares`
+   requires only `checked >= 8`, which phases 001 and 003 already satisfy on
+   their own, and `test_a_register_without_it_is_not_an_error` makes an absent
+   `linked` legal by design. That is the same shape as Claim 2 — an edge that
+   is silently absent and unreported — displaced from the past into the future.
+   Small fix; it belongs on the board rather than in another round.
+2. `perry-goals link` was tested against a **declared copy** and preserves all
+   nine `linked:` values across a rewrite (only `updated`, `tasks[]` and
+   `unlinked[]` move). The rescued edges are not at risk from the register's
+   own writer. Recorded because it was the one way Claim 2's fix could have
+   been undone by the next command anyone runs.
+3. The corrected RESULT says "four unsubstituted placeholders" and then lists
+   six. Cosmetic.
+4. `tests/test_parsers.py § test_the_phase_template_declares_no_krs_and_the_register_does`
+   ends `assertTrue(link.error or link.objectives)`. Measured:
+   `link.error == 'unfilled template placeholders'`, `link.objectives == []`, so
+   that assertion passes on the error branch alone and does not verify the
+   linkage template declares KRs. Weak rather than wrong — the docstring names
+   both branches — and the other three assertions in the test are real.
+5. `phase_key_results_by_objective` appends a register KR whose objective the
+   document has no heading for to the **last** objective. Documented as a
+   deliberate choice (keeping `kr_total` equal to the sum of the groups), but it
+   mis-groups silently. Not exercised by this branch's data.
+6. Consumer-visible content change, disclosed by the author and confirmed by
+   me: `perry-state --json` `phase.objectives[].krs[]` keeps its exact key set
+   and `kr_total` (8 before, 8 after, same ids, `qualifier` was already `""` on
+   both), but `metric` now carries the register's wording with the baseline
+   inline — up to ~300 bytes where the document's cell was `"0"`. A consumer
+   rendering that cell in a narrow column sees a different string. Not a
+   contract break; not a break I can rule out for a specific UI.
+7. `schema/state-schema.json` marks the phase KR table `"optional": true`, so
+   `perry-lint` will not report a project that hand-writes one back. Only this
+   repository's own test sweep does. The author states this and gives the
+   reason (a linter rule would false-positive on every unmigrated phase). I
+   agree with the trade.
+
+## Checked / not checked
+
+**Checked:** both audit claims, by full-suite measurement and by reading the
+documents at `8abd30d`; option (b)'s three surfaces and three refusals; the
+`003-linkage.md` additive diff; the fork-point duplication, re-measured with my
+own scanner; all twelve mutations with green-first and md5 restore, plus one of
+my own (`KR-O9.9`); the green-first check's motivating loader failure; three
+full-suite baselines; `perry-lint --root perry`; the register writer's
+preservation of `linked`; the payload key shape fork vs head; every new test
+read for the four vacuity modes named in the dispatch.
+
+**Not checked:**
+- **aiMark or any external consumer.** No access to it from here. The key shape
+  and `kr_total` are unchanged, but finding 6 is a real content change and
+  nobody has run a consumer against it. **I do not think it blocks**: the read
+  contract is intact, and the row that owns consumer breakage
+  (`P002-O3-KR2`) is a different row.
+- **Whether a CLI render is a good enough read surface.** DESIGN-013 § 6 defers
+  that to TASK-236 and no report exists. **I do not think it blocks this row
+  either**, and I want to be explicit about why rather than wave it through:
+  this is the *phase* KR table, 16% of one document with a 307-byte longest
+  cell, and the render reproduces it as the same markdown through the same row
+  renderer. The judgement DESIGN-013 is protecting is about `OKR.md` and
+  `BOARD.md`, which are what a human opens; a phase file's KR table is not.
+  Reversing this row later costs one command. If the PMO reads § 7 as making
+  *every* such move conditional on TASK-236's report, that is a decision call
+  above this review, and it should be made on the design rather than on this
+  branch's quality.
+- **`main` was not merged**, per the dispatch. I make no statement about the 7
+  files it also touches.
+
+## Verdict
+
+**PASS.** The audit was right on both counts and I confirmed both with my own
+measurements rather than by re-reading its arithmetic. The work it produced is
+the most carefully verified branch I have reviewed in this repository: twelve
+mutations that all reproduce, a harness that asserts green before it mutates,
+three named baselines that reproduce to the test, and a RESULT that says which
+agent measured what. Finding 1 should be filed as a row before the next phase is
+planned.

+
+An ordinary `add` onto the queue track, with the board's `## Intake` section
+present, is SAFE — 8240 bytes in, 8240 bytes out:
+
+```
+$ bin/perry-task add --title "a queue task probe" --track intake --priority P2 \
+    --deliverable "…" --verification "…"
+perry-task: wrote TASK-232 (add) → tasks.jsonl + intake.jsonl + journal + BOARD.md + event
+$ wc -c perry/intake.jsonl
+    8240 perry/intake.jsonl
+```
+
+Remove the `## Intake` section from `BOARD.md` — the state a project has
+before its first intake row, and the state `/pmo triage` can produce — and the
+identical command destroys the store:
+
+```
+$ python3 -c "…"   # delete the ## Intake section, nothing else
+$ wc -c perry/intake.jsonl
+    8240 perry/intake.jsonl        # 24 records
+$ bin/perry-task add --title "second queue probe" --track intake --priority P2 \
+    --deliverable "…" --verification "…"
+perry-task: wrote TASK-233 (add) → tasks.jsonl + intake.jsonl + journal + BOARD.md + event
+$ wc -c perry/intake.jsonl
+       0 perry/intake.jsonl        # 0 records
+$ bin/perry-lint
+  0 error(s), 5 warning(s)
+  · intake store: 0 record(s), 0 row(s) drifted
+```
+
+**Exit code 0. 24 records to 0. `perry-lint` calls it clean.**
+
+`cmd_add`'s queue branch calls `ensure_section("Intake")` at `bin/perry-task:2973`
+before `commit()` asks the gate at `:2549`, so the gate sees a freshly created,
+readable, EMPTY table, answers yes, derives `[]`, and writes zero bytes.
+
+## Why that is a merge blocker and the other three branches were not
+
+`coding/2026-08-29-overnight-batch` carries TASK-095's four wrong rounds and was
+merged, because the writer was measured on this repository's data first and does
+NOT refuse here — this project's config store and its `## Tracks` table agree, so
+the regression the round 5 reviewer found is not reachable on `main`.
+
+This branch is the opposite: the defect IS reachable on `main`, it destroys a
+canonical store rather than blocking a write, it is silent, and the linter
+reports the result as clean. There is no recovery short of the event log.
+
+Merging it would also make the row's own fix harder to verify: the invariant
+USER-906 chose — an ordinary write may never SHRINK a canonical store — has to
+be proved against a store that still has records to lose.
+
+## What round 4 does
+
+Round 4 starts from `main`, not from this branch. The branch stays for reference;
+whether it is rebased or abandoned is round 4's call once the invariant is in
+place. Requirements are on the row's Next action.
+
+The regression test comes FIRST and must be red before the fix: 24 records to 0
+on `perry-task add --track intake` with the `## Intake` section absent.

+# TASK-203 — the merge onto `main` is clean, measured before the review
+
+Measured 2026-08-30, ahead of the V4 verdict, so that a PASS can merge
+immediately instead of discovering a conflict afterwards.
+
+## The question
+
+`TASK-095` round 6 landed in `main` at `7f934d5` and edits `bin/perry-task`.
+`coding/task-203-round4` edits the same file. An earlier `git merge-tree` count
+was read as "one conflicting region"; that reading was wrong — the count matched
+"changed in both", not a conflict marker.
+
+## Textual merge
+
+```
+$ git merge --no-commit --no-ff coding/task-203-round4     # onto main
+Auto-merging bin/perry-task
+Automatic merge went well; stopped before committing as requested
+$ git diff --name-only --diff-filter=U
+(nothing)
+```
+
+**Zero conflicts.**
+
+## Semantic merge — the part a clean auto-merge does not prove
+
+Both branches edit `bin/perry-task`, so a textual merge succeeding says nothing
+about whether the result still means what either side intended. Both sides' own
+modules were run on the merged tree:
+
+| module | owner | result |
+|---|---|---|
+| `test_track_register_source` | TASK-095 round 6 | 57 tests, **OK** |
+| `test_register_store_invariant` | TASK-203 round 4 | 39 tests, **OK** |
+| `test_register_minters` | TASK-203 round 4 | 15 tests, **OK** |
+
+The writer also still runs on this repository's own data:
+`perry-task next … --dry-run` reports
+`would write TASK-077 (next) → tasks.jsonl + journal + BOARD.md + event`.
+
+## A note on the runner, because it cost a wrong reading here too
+
+`python3 -m unittest tests.test_track_register_source` fails with
+`ModuleNotFoundError: No module named 'gate'` — the module needs `tests/` on
+`sys.path`, which `bash tests/run` and `python3 -m unittest discover -s tests`
+both provide and a bare `-m unittest tests.X` does not. The first attempt above
+reported 2 import errors for exactly that reason and they were the invocation's,
+not the merge's. Recorded because "the runner disagrees with itself" has now
+produced three wrong readings on this project.
+
+## What this does NOT say
+
+It does not say `TASK-203` round 4 is correct — that is the V4 review's to
+decide, and the row has failed three rounds. It says only that **if** the review
+passes, the merge is mechanical.
+
+No full `tests/run` was taken on the merged tree; the three modules above were
+targeted. The probe worktree was discarded after measurement.

+# TASK-203 — pre-flight measurement: the risks half reproduces, and the success line is a template
+
+> Measured 2026-08-29 by the PMO, on a scratch copy, **before** any executor
+> touched the row. `TASK-203-spec.md § Baseline` asks for exactly this:
+> *"The risks half is stated by the row and has not been re-measured. Measure it
+> first … If the risks half does not reproduce, say so and narrow the row."*
+>
+> It reproduces. The row is not narrowed — it is **widened**, and the reason is
+> below.
+
+## Method
+
+The repository was copied to a scratch tree; every write below happened there.
+Each register was exercised with an *ordinary* write — the command a user or an
+agent actually runs — never with the one-way importer, which is the distinction
+the spec's `Deliverable` turns on.
+
+## Result
+
+| Register | Store | Ordinary write | Store after | Board after |
+|---|---|---|---|---|
+| tasks | `tasks.jsonl` | `perry-task next TASK-050` | **changed** ✅ | updated |
+| risks | `risks.jsonl` | `perry-task risk-add` → `RX-005` | **byte-identical** ❌ | updated |
+| risks | `risks.jsonl` | `perry-task risk-clear RX-005` | **byte-identical** ❌ | updated |
+| intake | `intake.jsonl` | `perry-task intake` | **still absent** ❌ | updated |
+| asks | `asks.jsonl` | `perry-task ask` → `USER-904` | **still absent** ❌ | updated |
+
+`risks.jsonl` md5 before `risk-add`: `d247ef83ae53cf9462f77afdc4e2ba5d`.
+After `risk-add`: `d247ef83ae53cf9462f77afdc4e2ba5d`.
+After `risk-clear`: `d247ef83ae53cf9462f77afdc4e2ba5d`.
+`grep -c "MEASUREMENT PROBE" perry/risks.jsonl` → `0`.
+`grep -c "MEASUREMENT PROBE" perry/BOARD.md` → `1`.
+
+So `risks.jsonl` is current only because it was imported once. It is a snapshot
+wearing a store's name, and it has been drifting silently since — `perry-lint`
+reports `risks store: 4 record(s), 0 risk(s) drifted` because the board is
+rendered from the same code path the store was minted from, not because the two
+were compared after a write.
+
+## The finding the row did not predict
+
+**Every one of those five commands printed the same success line:**
+
+```
+perry-task: wrote RX-005 (risk-add) → store + journal + BOARD.md + event
+perry-task: wrote the row (intake)  → store + journal + BOARD.md + event
+perry-task: wrote USER-904 (ask)    → store + journal + BOARD.md + event
+```
+
+`→ store` is **unconditional template text**, not a report of what happened. In
+three of the four registers it is false at the moment it is printed.
+
+This matters more than the missing writes themselves. `perry-task`'s whole claim
+on this project is that it is *"the one deterministic way Perry's state gets
+written"* — and the header of `bin/perry-task` tells the reader that a failed
+store write is *"reported, not raised."* It is not reported. It is announced as
+a success. An agent reading that line has been told the store is current, and
+on `risks` / `intake` / `asks` it never was.
+
+## What this changes about TASK-203
+
+- **The risks half stands.** Do not narrow the row.
+- **The row is three registers, not two.** `asks.jsonl` behaves identically and
+  is listed `Out of scope` in the spec on the reasoning that *"folding both into
+  one row is how a two-store change gets one store's worth of testing."* That
+  reasoning is still right and the scope line should stand — but the RESULT is
+  now required to propose the follow-up row, because the spec's own escape
+  clause (*"if the fix is genuinely shared, say so"*) has been triggered in
+  advance by measurement rather than discovered during the fix.
+- **A sixth verification step is owed**: the success line must become conditional
+  on the store write actually landing. A row that fixes three store writes and
+  leaves the unconditional `→ store` in place has fixed the registers and left
+  the lie.
+
+## Cleanup
+
+The probe rows (`RX-005`, one intake row, `USER-904`, and the `TASK-050 next`
+edit) exist **only in the scratch tree** and were never written to
+`/Users/bytedance/proj/Perry`. Nothing to revert.

+# TASK-203 — V4 review round 1: **FAIL**
+
+> Fresh-context reviewer, 2026-08-29, against `perry/evidence/2026-08/TASK-203-spec.md`.
+> Under review: `690b8c2` on `coding/task-203-register-stores`.
+> All destructive work on scratch copies; the worktree was read-only.
+
+## What holds, verified rather than restated
+
+**`REGISTER_EVENTS` is complete**, enumerated two ways. Statically: all ten
+`cmd_*` reaching `append_section_row` / `find_section_row` / `ensure_section` /
+`section_rows` against the three sections are declared. Empirically: all 26
+mutating subcommands run against a fixture carrying intake rows, a risk, an ask
+and a task, diffing each section against each store — **no command changed a
+section without changing that register's store**. `route` and `add` do touch
+`## Intake` and are declared; `cadence-add` / `cadence-done` touch none and are
+correctly omitted.
+
+**The canonical transaction is sound with three entries.** A crash harness
+(`os._exit(9)` after the N-th `os.replace`) at both rename boundaries: 3-entry
+marker, clean recovery, no leftovers, `drifted: 0`.
+
+**The four reported mutations all go red** — and two counts were under-reported
+upward (canonical-set drop was 8 not 6; the `answer` deletion was 2 not 1).
+
+**Both converted tests are legitimate.** The `asks` one added a content
+assertion and is stronger. The `intake` one is *"different, and stronger on the
+hazard"* — and the dropped drift coverage is not lost, because
+`test_a_row_deleted_by_hand_reports_every_row_it_renumbered` still carries it.
+
+## Finding 1 — BLOCKING. The exemption is keyed on the command, the hazard is not
+
+The commit message claims this defect was prevented. **It describes this
+branch's behaviour.**
+
+`REGISTER_RENUMBERING` exempts `intake-sweep` because that command moves rows.
+But the hazard is *whether the board's intake rows have moved since the store
+was last written*, which `register_change` never checks. `intake-sweep` is the
+only command that moves rows **itself**; it is not the only way rows move.
+
+Reproduced — a human tidies one discharged row out of `## Intake` by hand, then
+does something else entirely:
+
+```
+STORE, correct:
+{"order":0,"request":"A - already dropped","outcome":"dropped …","discharged":true}
+{"order":1,"request":"B - still waiting","outcome":"—","discharged":false}
+{"order":2,"request":"C - still waiting","outcome":"—","discharged":false}
+
+  ← row A deleted from BOARD.md by hand
+  ← perry-task add --title "unrelated task"      (rc 0)
+
+STORE, after:
+{"order":0,"request":"B - still waiting","outcome":"—","discharged":true}   ←
+{"order":1,"request":"C - still waiting","outcome":"—","discharged":false}
+
+perry-lint: {"records": 2, "drifted": 0}
+```
+
+A live, undischarged request is recorded as discharged, its `Outcome` cell
+still reads `—`, and drift says clean — `discharged` has no board column to
+compare against. `intake_record` then carries that `True` forward **on every
+subsequent write, permanently.**
+
+Enumerated across all five intake events: `add`, `intake`, `resolve-intake` and
+`route` all reproduce it; only `intake-sweep` is protected. `add` is the worst
+— on a project-mode track it does not touch `## Intake` at all, which is exactly
+what the change's own comment says the design refuses to do.
+
+Proof: `bin/perry-task:2163`, `:2212-2216`, `bin/perry_store.py:1012`.
+
+## Finding 2 — BLOCKING. The gate lets an unrelated write truncate a store to zero
+
+`bin/perry-task:2205`: `if not board.has_section(section) and not path.exists():`
+
+When the store **exists** and the board section does **not**, the gate declines
+to decline, the derivation returns `[]`, and `store_text([])` is written:
+
+```
+intake.jsonl before: 3 records (one discharged, two live)
+BOARD.md: `## Intake` removed
+perry-task add --title "an ordinary task"      rc 0
+intake.jsonl after:  '' — 0 records
+```
+
+`load_register_records`' own docstring eleven lines above states the rule this
+violates: *"these three are canonical, and silently discarding a record would
+let the next write persist the smaller set as truth."* The write is inside the
+canonical transaction, so it is durable and atomic; the store is not
+recoverable from the board, because the board is what is missing.
+
+The closing mutation — tightening to `if not board.has_section(section):` — is
+**green across the full suite**. The clause that makes the wipe reachable is
+load-bearing for no test at all.
+
+## Finding 3 — green mutation. The stored-record merge is untested
+
+Replacing `current = load_register_records(path)` with `current = None`, which
+deletes the entire two-source merge, is **green across 2803 tests**.
+`discharged` / `cleared` / `answered` carry-forward has no test in the tree.
+That is *"the 'one store's worth of testing' the Out-of-scope line was worried
+about, realized across all three registers rather than avoided."*
+
+## Finding 4 — a comment asserts a guard that does not exist
+
+`bin/perry-task:2126-2129` claims `tests/test_register_stores.py` asserts *"that
+every command mutating one of the three sections has its event declared."* It
+does not — all three tests in `TestTheMapIsCompleteAndReal` run in the forward
+direction. The residue is visible: `SECTION_OF` is defined and **never read**.
+
+*"On a task whose subject is a success line that asserted a write nobody
+performed, a comment asserting a test nobody wrote is the same shape."*
+
+## Finding 5 — three citations point at a file the branch does not carry
+
+`bin/perry-task:2121`, `:6983` and `tests/test_register_stores.py:9` all cite
+`evidence/2026-08/TASK-203-premeasurement.md`, which is not in the commit and
+appears in no commit in `git log --all`. It was written to the PMO tree and
+never added to the branch. The commit's central four-register table rests on it.
+
+Relatedly, verification item 1 as written — *"`perry-lint --root .` prints a
+real drift verdict for all six stores"* — is not reproducible on the branch,
+because the stores mint on first write and no write has run against Perry's own
+state. The property holds on a fixture; the claim does not describe the commit.
+
+## Baseline
+
+`690b8c2` = 2803 tests / 8 failures / 4 modules; `45a355d` = 2786 / same 8 /
+same 4. Byte-identical sets; the +17 are `test_register_stores.py`. **This
+change adds no failure** — but the reported baseline of "3 modules, 5 failures"
+omits `test_risks_store.TestTheReadersAreOneFunction` (3), *"which is one of the
+three registers this change touches."*
+
+## Verdict
+
+```
+=== VERDICT ===
+task: TASK-203
+rung: V4
+result: FAIL
+criteria: perry/evidence/2026-08/TASK-203-spec.md
+checked: all destructive work on scratch copies (branch, base from git archive
+         45a355d, seven mutant trees). Full suite both trees: 690b8c2 2803/8/4,
+         45a355d 2786/8/4, identical sets. Author's 4 mutations re-run on 4
+         separate trees — 8, 4, 2, 1 red (two under-reported upward). Own
+         mutations: `current = None` GREEN on 2803; remove the validation
+         Refused green; tighten the gate GREEN. Category enumerated twice —
+         static walk of all cmd_* against the three sections (10, all declared)
+         and an empirical sweep of all 26 mutating subcommands diffing sections
+         against stores. Finding 1 enumerated across all five intake events.
+         Finding 2 reproduced: 3 records → 0 bytes. Crash recovery exercised at
+         both rename boundaries. Spec criteria 1 and 2 verified on a fixture.
+not-checked: TASK-203-premeasurement.md — absent from the commit and from
+         `git log --all`, so the four-register pre-measurement is unverified;
+         re-deriving it means running write commands, which the constraints
+         forbid against the project under review. `route`'s half of Finding 1
+         used a synthetic two-track config. Concurrency under parallel writers,
+         Windows and network filesystems, localized boards, and
+         `perry-tasks *-render --write` interaction were not exercised. Did not
+         audit whether aiMark or perry-state surface `discharged` to a user.
+         The `--group "Top risks"` abuse path (and `prioritize` being absent
+         from REGISTER_EVENTS) is pre-existing and was not pursued.
+proof: bin/perry-task:2163 with the merge at :2212-2216 and the carry-forward at
+       bin/perry_store.py:1012 — `add`, `intake`, `resolve-intake` and `route`
+       all write `discharged: true` onto a live undischarged intake row when the
+       board's rows shifted by any means other than a sweep, and perry-lint
+       reports drifted 0. Second: bin/perry-task:2205 —
+       `if not board.has_section(section) and not path.exists():` — an unrelated
+       `perry-task add` truncates an existing 3-record intake.jsonl to zero
+       bytes when `## Intake` is absent; the closing mutation is green across
+       all 2803 tests.
+=== END VERDICT ===

+# TASK-203 — V4 review round 2: **FAIL**
+
+> Fresh-context reviewer, 2026-08-29, against `perry/evidence/2026-08/TASK-203-spec.md`.
+> Under review: `9b4ae3d`. All destructive work on scratch copies; the worktree
+> was read-only and clean at start and end.
+
+## What round 2 fixed, verified
+
+**Finding 2's original door is shut.** Whole-tree SHA-256 before/after an
+unrelated `add` with the section missing: `intake.jsonl` byte-identical.
+
+**The data-keyed check subsumes the command-name exemption for the ordinary
+shapes** — ten board mutations run end-to-end, nine correct.
+
+**Crash safety re-verified with the 3-entry canonical set** — `os._exit(9)`
+after the 1st, 2nd and 3rd `os.replace`: clean forward recovery at all three,
+no leftovers.
+
+**`REGISTER_EVENTS` is still complete both ways.** The new reverse guard walks
+25 `cmd_*`, finds 11 naming a section, checks the 10 that emit an event literal.
+
+**Baseline accurate in both runners** — `9b4ae3d` 2808/8 vs `45a355d` 2786/8,
+byte-identical failure sets. *"The round-1 complaint about reporting one runner
+without saying which has been fixed."*
+
+## Finding 1 — BLOCKING. The data it asks is not unique
+
+`bin/perry-task:2192-2193` decides identity on `(request, arrived)`. **Two
+intake rows with the same Request on the same day is not exotic — it is the
+same thing filed twice, which is the ordinary reason a row gets `dropped —
+duplicate`.** Every row `perry-task intake` writes gets today's date, so on a
+busy day `arrived` contributes nothing and identity collapses to the Request
+string alone.
+
+```
+STORE, correct:
+{"order":2,"request":"fix the login bug","outcome":"dropped … folded in","discharged":true}
+{"order":3,"request":"fix the login bug","outcome":"—","discharged":false}
+
+  ← the dropped duplicate tidied out by hand
+  ← perry-task add "an ordinary task"      (rc 0)
+
+{"order":2,"request":"fix the login bug","outcome":"—","discharged":true}   ←
+perry-lint: {"records": 3, "drifted": 0}
+```
+
+Round 1's Finding 1, unchanged, and carried forward permanently by two further
+writes. `bin/perry-tasks:1313` computes `undischarged` off store records, so the
+row is now invisible to the count that makes an over-cap queue mean "not being
+drained".
+
+> *"The commit message's own framing applies to itself: keying on the command
+> name was the wrong question, and keying on a non-unique tuple is the same
+> mistake one level down."*
+
+**The fix is five lines** — refuse the join when the stored identity tuples are
+not unique. The reviewer applied it on a copy: correct result, **and all 22
+shipped register tests stay green**, which is itself proof no test distinguishes
+the two behaviours.
+
+## Finding 2 — BLOCKING. One door of four
+
+`bin/perry-task:2237` guards only `has_section == False`. The derivation returns
+`[]` for **four** board states: `intake_section_shape` returns `None` for
+`absent`, **`prose`** and **`foreign`** too. Measured, rc 0 each time:
+
+```
+A. the table replaced by a sentence      → intake.jsonl 0 bytes
+B. `Request` column renamed to `Ask`     → intake.jsonl 0 bytes
+C. a legend table added under `## Intake`→ intake.jsonl 0 bytes
+```
+
+And on asks the truncating command is the register's **own**: a legend table
+under `## User Input Queue`, then `perry-task ask` → `asks.jsonl` 0 bytes.
+
+> *"The commit message states the correct principle — 'A board that lost a
+> section while its store still holds records is DRIFT' — and then implements it
+> for one of the four shapes that lose the rows. The shipped test asserts
+> exactly the one case that was reported and no other; that is what left the
+> other three standing."*
+
+## Finding 3 — BLOCKING. The merge is still untested, and my mutation measured a crash
+
+My `current = None` mutation is red **incidentally**: `current` now feeds
+`positions_still_hold`, whose comprehension raises `TypeError` before any merge
+happens. The honest form — `current = []` — is **GREEN across all 2808 tests**,
+`TestTheStoredRecordMergeIsRealAndBounded` included.
+
+The reason is in the test: `test_a_discharged_flag_survives_an_unrelated_write`
+discharges via `resolve-intake`, which writes `dropped … folded in` into the
+`Outcome` cell, and `intake_record` **re-derives** `discharged` from that cell
+when the store says nothing. The flag it asserts survives is re-derivable from
+the board, so deleting the merge cannot make it fail.
+
+Three more, each green across 448 tests: dropping `arrived` from the identity
+tuple; `was is None` → `return False`; passing `current` to the probe.
+
+Only one of my four reported counts is exact.
+
+## Finding 4 — non-blocking. The reverse guard is evadable, and `SECTION_OF` is still dead
+
+Two plants pass silently: one building its event name from a variable (the
+regex finds nothing, `if not events: continue` skips it), one reaching the
+section through `perry_store.INTAKE_SECTION` — *"the guard is keyed on the
+spelling the codebase's own comment discourages, which is also why it cannot
+see a localized board."*
+
+And `sections = set(self.SECTION_OF.values())` is **assigned and never read** —
+the guard hardcodes the same literals four lines later. *"Round 1's Finding 4
+was a comment asserting a guard that does not exist; this is a smaller instance
+of the same shape."* The `{"cadence-add", "cadence-done"}` exemption is keyed on
+command names, in the test that exists because keying on command names was the
+defect.
+
+## (a) The double derivation — sound, and cheap
+
+Equivalent for the question asked; 0.16s / 0.24s / 0.45s at 100 / 1000 / 4000
+rows. One waste: the probe is computed unconditionally, including for `risks`
+and `asks` where the answer is `True` without reading it.
+
+## (c) `positions_still_hold` and a new row — correct, and untested
+
+Append-at-end preserves the merge; insert-at-0 and insert-mid correctly drop it.
+*"The branch is correct — and m6 shows nothing tests it."*
+
+## Verdict
+
+```
+=== VERDICT ===
+task: TASK-203
+rung: V4
+result: FAIL
+criteria: perry/evidence/2026-08/TASK-203-spec.md
+proof: bin/perry-task:2192-2193 — `(request, arrived)` is not a unique key. Two
+       intake rows with the same Request on the same day, the discharged one
+       tidied out by hand, then `perry-task add` (rc 0): the survivor is written
+       `"discharged": true` with `"outcome": "—"`, perry-lint reports
+       {"records": 3, "drifted": 0}, and two further writes carry it forward.
+       Second: bin/perry-task:2237 with bin/perry_store.py:1039-1040 — the gate
+       covers only the missing section; the derivation also returns [] for
+       `prose` and `foreign`, so a 3-record intake.jsonl goes to 0 bytes on an
+       unrelated `add` when the Request column is renamed, a sentence replaces
+       the table, or a legend table joins the section — and a 1-record
+       asks.jsonl goes to 0 bytes on `perry-task ask`. Third:
+       `current = []` at bin/perry-task:2261 is green across all 2808 tests, so
+       the two-source merge is still uncovered; the mutation the commit reports
+       as red goes red on a TypeError, not on the merge.

+# TASK-203 — V4 review round 3: **FAIL**
+
+> Fresh-context reviewer, 2026-08-29, against `perry/evidence/2026-08/TASK-203-spec.md`.
+> Under review: `d075698`. All destructive work on scratch copies; the worktree
+> stayed clean.
+>
+> *Interruption note, the reviewer's own:* the PMO killed their first
+> `bash tests/run` on the base copy mid-run and said so. **It was re-run from
+> scratch and every number below comes from the complete re-run.**
+
+## What round 3 fixed, verified
+
+**All four claimed mutations reproduce to the exact count** (2 / 1 / 2 / 7).
+
+**Finding 3 is genuinely closed** — the new merge test is red under the *honest*
+`current = []`, and red for the named reason. **Both self-reported
+"green for the wrong reason" corrections are real.**
+
+**Finding 2's behaviour is fixed for all four shapes and all three registers** —
+a 60-cell matrix (3 registers × 5 shape variants × store present/absent ×
+own/unrelated write). *"No cell truncates a present store to zero through a
+shape the gate can see."*
+
+`readable_as_register` is correct for all three and a `KeyError` is impossible.
+`REGISTER_EVENTS` complete both ways over all 21 mutating subcommands. Crash
+recovery holds at all three rename boundaries. Five refusal paths hashed
+whole-tree: nothing written. Localized `zh` board correct for all three
+registers. Baseline verified on both runners, failure sets byte-identical.
+
+## Finding 1 — BLOCKING. The gate is read at a moment the command controls
+
+`cmd_add`'s queue-mode branch calls `ensure_section("Intake", …)` at
+`bin/perry-task:2973`. `commit()` asks the gate at `:2549` — **after** that
+mutation. So the gate is asked about a board state the command it guards has
+already destroyed: it sees a freshly created, perfectly readable, **empty**
+intake table, answers yes, derives `[]`, and writes `store_text([])` into the
+canonical transaction.
+
+```
+intake.jsonl before:  291 bytes, 3 records
+  ← `## Intake` removed from BOARD.md by hand
+  ← perry-task add --title "a queue task" --track ops        (rc 0)
+intake.jsonl after :  0 bytes, 0 records
+perry-lint: intake store: 0 record(s), 0 row(s) drifted
+```
+
+On `45a355d` the same file is **byte-identical** after the same command.
+
+> *"This is round 1's blocking finding restated without a word altered … Same
+> command name, same board state, same zero bytes. Round 2 closed it for the
+> project-mode track; the queue-mode track — the mode `## Intake` exists for —
+> was never asked."*
+
+**The shipped regression test is one word from red.** Give
+`test_a_present_store_is_never_emptied_by_a_write_that_lost_its_section` a
+`--track ops` fixture and nothing else, and it fails `0 != 1`.
+
+Enumerated, section deleted by hand then one command — every loss silent, rc 0,
+permanent, canonical, and reported by `perry-lint` as `0 row(s) drifted`:
+
+| register | command | before → after |
+|---|---|---|
+| intake | `add --track ops` | 3 → **0** |
+| intake | `intake` | 3 → **1** |
+| asks | `ask` | 3 → **1** |
+| risks | `risk-add` | 3 → **1** |
+
+All four are byte-identical on base.
+
+> *"The outcome for a given board now depends on which command you happen to run
+> next. Round 1 keyed the exemption on the command name and was told the question
+> was wrong; round 2 keyed it on a non-unique tuple; round 3 keyed it on the
+> shape — and the shape is read at a moment the command controls."*
+
+## Finding 2 — non-blocking. My third shape test is vacuous, same blind spot moved
+
+`test_a_second_table_under_the_heading` appends the legend table to the **end of
+the file** — but `ensure_section` anchors `## Intake` *before* `## P0`, so the
+last section is `## Top risks` and **the legend lands there.** `## Intake` stays
+a clean single-table section, the gate is never asked about `foreign`, and the
+assertion passes trivially. Green with the gate reverted and green with
+`readable_as_register` weakened.
+
+**The `foreign` shape has no test at all, for any register** — two of the four
+shapes Finding 2 named, and the one where round 2 showed the truncating command
+was the register's own.
+
+> *"The author caught two green-for-the-wrong-reason tests by mutation and
+> shipped a third of the same class in the same commit, uncaught, because the
+> mutation that would have exposed it was read as '2 failures, as expected'
+> rather than 'why only 2 of 3?'."*
+
+## Finding 3 — non-blocking. The uniqueness test cannot tell uniqueness from adjacency
+
+The duplicate pair sits at orders 2 and 3 — **adjacent**. A weaker guard tripping
+only on *consecutive* equal identities is **green across all 2815 tests**. So is
+round 2's `(request, arrived)` → `(request,)`: `arrived` is a decoration on the
+tuple that nothing asserts.
+
+## (a) The uniqueness refusal is over-broad, and correctly so
+
+Measured three ways: with `Outcome` cells intact, ten ordinary writes leave
+`intake.jsonl` **byte-identical**. The only thing the join carries is
+`discharged`, which `intake_is_discharged` re-derives from any non-blank
+`Outcome`. The realistic loss is one boolean on rows a human has hand-blanked,
+and the error direction is safe — a discharged row is re-reported as waiting,
+never the reverse. *"Materially better than round 2, which fabricated a
+discharge."*
+
+## (b) `prose` does not lock `intake` out
+
+`ensure_section` returns early when the heading exists, so it does **not** turn a
+prose section into a table — `intake_section_shape`'s docstring saying it does is
+wrong. `append_section_row` refuses first. *"There is no path where `intake` on a
+prose section silently skips the store forever."*
+
+## (c) Two asymmetries survive, both pre-existing
+
+On a `foreign` section `risk-add` refuses with an explanation while `intake` and
+`ask` return rc 0, append a row and skip the store — and on a renamed key column
+the request text is dropped from the board row too. And on the id-keyed
+registers a duplicate id **on the board** now silently deletes a stored record,
+while a duplicate **in the store** leaks one record's `cleared` onto the other.
+*"Both live in `perry_store` and predate the row, but they were unreachable until
+this change made ordinary commands write those files."*
+
+## (e) The flake did not reproduce — ~70 executions
+
+6 isolated, 8-way concurrent × 7 tests, 4 full suites, both trees, both runners —
+**never red.** *"I could not reproduce it and I am not accepting the author's
+account of it either; I am recording that it did not appear."* A plausible
+mechanism is named (a `recover_stale_lock` TOCTOU) and marked a reading, not a
+measurement.
+
+## Smaller
+
+- **A corrupt line in a register store is now an uncaught traceback.**
+  `load_register_records` lets `JSONDecodeError` escape; nothing is written, but
+  every other failure in the file is a `Refused` with a way forward. Before this
+  row, a corrupt `risks.jsonl` did not affect `risk-add` at all.
+- **`readable_as_register`'s `section` parameter is dead** — declared, passed,
+  never read. *"In the same commit that answers a review finding about
+  `SECTION_OF` being assigned and never read."*
+
+## Verdict
+
+```
+=== VERDICT ===
+task: TASK-203
+rung: V4
+result: FAIL
+criteria: perry/evidence/2026-08/TASK-203-spec.md
+proof: bin/perry-task:2297 (the gate) is asked by commit() at :2549, which runs
+       AFTER cmd_add has already called `ensure_section("Intake", …)` at :2973
+       on a queue-mode track. The gate sees a freshly created, readable, EMPTY
+       intake table, derives [], and writes store_text([]) inside the canonical
+       transaction. Measured on a 3-record 291-byte intake.jsonl, `## Intake`
+       removed by hand, then `perry-task add --title "a queue task" --track ops`
+       (rc 0): 0 bytes, 0 records, perry-lint `0 row(s) drifted`. On 45a355d the
+       same file is byte-identical. Round 1's Finding 2 unchanged. The shipped
+       regression test goes red when its fixture is given `--track ops` and
+       nothing else. Same door three more times, all rc 0 and all preserved on
+       base: intake 3→1, ask 3→1, risk-add 3→1. Second, non-blocking:
+       test_a_second_table_under_the_heading appends its legend to the end of
+       the file, which is under `## Top risks` — ensure_section anchors
+       `## Intake` before `## P0` — so the section is never `foreign` and the
+       test is green with the gate reverted. The `foreign` shape has no test on
+       any register.

+# TASK-203 — round 4 RESULT: one invariant, and the two places it is thinner than it looks
+
+> **SUPERSEDED IN PART by `TASK-203-round5-result.md`, which is the current
+> document for this row.** Round 4 FAILED its V4 review
+> (`TASK-203-round4-v4-review.md`) on a fifth door that was not in the
+> invariant but in the exemption around it: `SHRINK_ALLOWED` granted its

+## 0. Commits
+
+| commit | what it is |
+|---|---|
+| `762bee1` | the three registers get their store writes — **and nothing that stops the write going wrong.** Deliberately RED. |
+| `b09776d` | the invariant. |
+| `6d45388` | the refusal's recovery line named `perry-tasks tasks-write`, which does not exist; `--dry-run` gets a test. |
+| `70dfa96` | the `tasks.jsonl` call site gets a test that fails when it is deleted. |
+
+## 1. The invariant as implemented, and where it lives
+
+`bin/perry-task § refuse_to_shrink`, one function:
+
+```python
+SHRINK_ALLOWED = frozenset({"purge", "resolve-intake", "intake-sweep"})
+
+def refuse_to_shrink(store, path, event_name, before, after, why="") -> None:
+    if after >= before or event_name in SHRINK_ALLOWED:
+        return
+    raise Refused(...)
+```
+
+Two call sites, and only two:
+
+| store | call site | what it counts |
+|---|---|---|
+| `tasks.jsonl` | `commit()` — `bin/perry-task:2627` | `len(current)` vs `len(records)` |
+| `risks.jsonl` / `intake.jsonl` / `asks.jsonl` | `register_change()` — `bin/perry-task:2352` | records on disk vs records derived |
+
+**Why this is not a fourth predicate.** It asks nothing about the command, the
+identity of a row, or the shape of a section. It asks whether the derivation
+produced fewer records than the store already holds. That one question answers
+all four doors, because each of them reaches the store the same way:
+
+- **the command name (round 1)** — a row tidied off the board by hand and then
+  *any* ordinary write: the board derives n−1 records against a store of n.
+- **the non-unique identity tuple (round 2)** — the same scenario with two rows
+  sharing a Request. The tuple is never consulted; the count already refused.
+- **the four section shapes (round 2, round 3)** — `<register>_records` returns
+  `[]` for `absent`, `prose`/`bullets` and both `foreign` shapes. `0 < n` is the
+  refusal. The gate does not enumerate shapes.
+- **`ensure_section` ordering (round 3)** — `cmd_add`'s queue branch creates the
+  section before `commit()` reads anything, so a gate that asks about the board
+  is asked about a board the command already changed. **A count does not care
+  when it is read.** That is exactly why option A — snapshotting the gate at
+  command entry — is not needed, and it is not implemented.
+
+**The one thing it deliberately allows.** A shrink is not always wrong; it is
+wrong when nobody asked for it. `SHRINK_ALLOWED` is a frozenset of the three
+names USER-906 gave, not a predicate about board state.
+
+### What else the branch carries
+
+`762bee1` is the feature the row was originally for — the three registers being
+written by an ordinary command at all. It rebuilds, rather than patches, the
+parts of `coding/task-203-register-stores` the three reviews found sound:
+`REGISTER_EVENTS`; the register store joining `replace_canonical_pair`'s
+canonical set so the recovery marker covers it; `carry_forward_is_addressable`
+(round 2/3's `positions_still_hold`), which is **not** the invariant — § 5; and
+a success line naming the files the write actually touched, which is the sixth
+verification step `TASK-203-premeasurement.md` asked for, since `→ store` was
+unconditional template text and was false on `risk-add`, `intake`, `ask` and
+`answer` at the moment it printed.
+
+## 2. The regression test came first, and was red
+
+`main` at `6c0d041` carries none of the register-store code, so a test asserting
+"the store is not truncated" is **vacuously green** there. The honest sequencing
+is therefore two commits, and a reviewer can reproduce both numbers:
+
+```
+$ git checkout 762bee1 && cd tests
+$ python3 -m unittest test_register_store_invariant
+Ran 37 tests — FAILED (failures=24, errors=7)
+
+$ git checkout b09776d && cd tests
+$ python3 -m unittest test_register_store_invariant
+Ran 37 tests — OK
+```
+
+The 7 errors at `762bee1` are the five unit tests of `refuse_to_shrink`, which
+does not exist at that commit. The 24 failures are the doors. (The tip carries
+39 tests; the two extra came in `6d45388` and `70dfa96`.)
+
+Outside the suite, on a probe project with the same queue-mode track shape this
+repository declares in `.perry/config.md § Tracks`:
+
+```
+before:  intake.jsonl  344 bytes / 3 records   md5 6f6438d04960f0aad12f94eb0c9e619c
+         `## Intake` deleted from BOARD.md by hand
+$ bin/perry-task add --title "a queue task probe" --track ops …
+perry-task: refused — `add` would take …/intake.jsonl from 3 record(s) to 0,
+and an ordinary write may never make a canonical store smaller (USER-906).
+Nothing was written.
+rc=1
+after:   intake.jsonl  344 bytes / 3 records   md5 6f6438d04960f0aad12f94eb0c9e619c
+$ bin/perry-lint
+  1 error(s), 5 warning(s)
+  · intake store: 3 record(s), 3 row(s) drifted
+```
+
+At `762bee1` the identical command exits **0**, leaves **0 bytes**, and
+`perry-lint` reports `0 error(s)` and `intake store: 0 record(s), 0 row(s)
+drifted` — the merge-hold reproduction, on a store with records to lose.
+
+## 3. Every door it closes, with the named test that proves it
+
+All tests are in `tests/test_register_store_invariant.py` unless named
+otherwise.

+| **door 3, `foreign` alone** — 6 cells, stated on its own | round 3 finding 2 | `TestTheFourDoors.test_door_three_the_foreign_shape_is_refused_on_every_register` |
+| **door 4** — `ensure_section` rebuilding a section from one row, all three registers | round 3 finding 1 | `TestTheFourDoors.test_door_four_a_register_command_may_not_rebuild_its_section_from_one_row` |
+| `intake-sweep` may still shrink | spec item 7 | `TestExplicitRemovalStillWorks.test_intake_sweep_may_shrink_the_intake_store` |
+| `purge` may still shrink `tasks.jsonl` | spec item 7 | `TestExplicitRemovalStillWorks.test_purge_may_shrink_the_task_store` |
+| `resolve-intake` is not blocked | spec item 7 | `TestExplicitRemovalStillWorks.test_resolve_intake_is_not_blocked_and_does_not_in_fact_shrink` |
+| the rule itself, at the boundary and on the allowlist | — | `TestTheInvariantItself` (5 tests) |
+| `commit()` actually asks it about `tasks.jsonl` | § 6 finding 1 | `TestTheTaskStoreCallSiteIsWired.test_commit_asks_the_invariant_about_tasks_jsonl` |
+| an ordinary write reaches its store; lint prints a verdict; `intake-diff` clean | spec items 1–2 | `TestTheOrdinaryWriteReachesItsStore` (5 tests) |
+| `REGISTER_EVENTS` complete both ways | round 1 finding 4 | `TestTheMapIsComplete` (4 tests) |
+
+## 4. The four round-3 findings that are not the invariant
+
+**1. The `foreign` shape had no test on any register.** Round 3's legend table
+was appended to the end of the board file, which put it under `## Top risks`,
+because `ensure_section` anchors `## Intake` before `## P0`. Three things close
+it here, and the first two are controls that exist only to stop this module
+repeating the mistake:
+
+- `TestTheFixturesAreTheShapeUnderTest.test_every_shape_fixture_really_is_the_shape_it_claims`
+  hands all 15 fixture boards (3 registers × 5 shapes) to `perry_store`'s own
+  `<register>_section_shape` and asserts the answer.
+- `…test_the_foreign_legend_lands_inside_the_named_section` asserts the legend
+  text is inside the named section's body — the precise defect, as a fact about
+  the text.
+- `test_door_three_the_foreign_shape_is_refused_on_every_register` re-asserts
+  the shape **inside** the behaviour test, so the assertion cannot pass through
+  a section that is not foreign.
+
+Both `foreign` variants are covered: a second table under the heading, and the
+key column renamed (`Request`→`Ask`, `Needed from user`→`Wanted`,
+`Risk`→`Hazard`).
+
+**2. The uniqueness test could not tell uniqueness from adjacency.**
+`TestTheCarryForwardJoin.test_a_repeated_identity_is_no_identity_even_when_no_two_are_adjacent`
+is a unit test on `carry_forward_is_addressable` with stored identities
+`A, B, A, B` — duplicated at 0/2 and 1/3, **never adjacent** — and derived rows
+sitting at exactly the stored positions. Two control assertions inside the test
+make the claim falsifiable rather than asserted: no two neighbouring identities
+are equal, and every derived row matches its stored position, so the positional
+check cannot be what answers. Mutation **M6** replaces the uniqueness clause
+with a consecutive-only one; that is the distinction round 3 said could not be
+made.
+
+**3. `load_register_records` let `JSONDecodeError` escape.** It now raises
+`Refused` naming the file, the **line number** and the parser's message, in the
+shape `load_task_records` already uses.
+`TestTheStoreIsReadHonestly.test_a_corrupt_line_in_a_register_store_is_a_refusal_not_a_traceback`
+asserts no `Traceback`, the store's name, and `line 5`.
+
+**4. `readable_as_register`'s `section` parameter was dead.** The function is
+now `register_section_shape(board, key)` — the heading is looked up from
+`REGISTER_SPEC`, which is where it is declared — and it returns the shape
+string rather than a bool, so the refusal can say *"`## Intake` is currently
+`prose`, not a table this store can read"*.
+`…test_register_section_shape_reads_every_argument_it_takes` asserts the
+signature is `(board, key)` and that both names appear in the body.
+
+## 5. What the invariant does NOT cover, and what covers it instead
+
+**A row REPLACED by hand does not move the count.** Delete a discharged intake
+request and append a new one: the board still derives n records against a store
+of n, the invariant is silent, and a positional merge would hand
+`discharged: True` at position k to a request that is still waiting — with its
+`Outcome` cell reading `—` and `perry-lint` reporting `drifted: 0`, because
+`discharged` has no board column to compare against.
+
+`carry_forward_is_addressable` answers that, and this RESULT states plainly what
+it is: **not the invariant, and not a gate on any write.** It decides only
+whether the one stored field a register's board has no column for —
+`discharged`, `cleared`, `answered` — may be carried across. Answering `False`
+drops a boolean; it never permits a write `refuse_to_shrink` forbids and never
+forbids one it permits. The end-to-end proof is
+`TestTheCarryForwardJoin.test_a_row_replaced_by_hand_does_not_hand_its_discharge_to_the_newcomer`,
+which is an `rc == 0` write — the store IS updated — asserting the newcomer is
+not marked discharged.
+
+Keeping it is the one place round 4 kept a predicate from an earlier round, and
+it is a judgement call. The reasoning: the invariant answers *may this write
+happen*, this answers *is this join addressable* — two questions with two
+consequences, and collapsing them would either block a legal write or fabricate
+a discharge. Round 3's reviewer measured the same guard as *"over-broad, and
+correctly so"*, and its error direction is safe: a discharged row is
+re-reported as waiting, never the reverse.
+
+## 6. Two findings that are thinner than the rest, stated as findings
+
+### Finding 1 — the `tasks.jsonl` call site survived its own deletion, and now does not
+
+**The precise shape, because "reddens nothing" was too coarse.** Two
+mutations bracket it:
+
+- **M2**, emptying `SHRINK_ALLOWED`, reddens **21** tests, **14 of them in
+  `test_purge`** — `perry-task purge` refuses end-to-end through the CLI. So
+  `commit()`'s call site IS reached on every task write, and its allowlist
+  branch is exercised by an ordinary command.
+- **M3**, deleting the call site outright, reddened **nothing** before
+  `70dfa96` and reddens exactly **one** test after it. What was unreachable was
+  never the call, only its *refusal* branch.
+
+The original measurement, and why it mattered: deleting
+
+```python
+refuse_to_shrink("tasks", perry_store.store_path(state_root),
+                 event.get("event") or "", len(current), len(records))
+```
+
+from `commit()` reddened **nothing**. `TestTheInvariantItself` unit-tests the
+rule; it says nothing about whether `commit()` asks it. A refusal branch that
+survives its own deletion is the shape TASK-095 shipped and was failed for, so
+leaving it as "an assertion" would have been the wrong answer.
+
+**Why it is hard to reach, stated rather than worked around.** `commit()` builds
+`records` FROM `current` by removing at most one record and appending at most
+one, so the only branch that shortens the task store is `purge` — which is in
+`SHRINK_ALLOWED`. The one other input that shortens it is a store carrying the
+subject's id twice, and `load_task_records` refuses a duplicate id before
+`commit()` ever sees it. **The state the guard exists for is unreachable through
+the CLI today.**
+
+`70dfa96` adds
+`TestTheTaskStoreCallSiteIsWired.test_commit_asks_the_invariant_about_tasks_jsonl`,
+which constructs that state deliberately by replacing `load_task_records` for
+the duration of one `commit(..., dry_run=True)` call. **It proves the refusal
+branch is wired. It does not claim the state is reachable**, and the test's own
+class docstring says so in those words. `--dry-run` is used deliberately: a
+build with the call site deleted then writes nothing while still going red.
+
+    M3, before 70dfa96:  Ran 178 — 0 red
+    M3, at the tip:      Ran 178 — FAILED (failures=1)
+                         RED test_commit_asks_the_invariant_about_tasks_jsonl
+
+A reviewer who holds that a call site reachable only under a monkeypatch should
+not ship has a fair case for deleting those two lines. I kept them because they
+are the same function the three registers call, at the one place that can see
+both counts, and because `commit()`'s task branch is exactly the code a future
+edit would break without noticing.
+
+### Finding 2 — `resolve-intake` does not reduce any count
+
+`cmd_resolve_intake` rewrites the row's `Outcome` cell:
+
+```python
+ctx["board"].lines[idx] = render_row(
+    [intake.get(k, "") if k != "outcome" else text for k in keys])
+```
+
+The row stays on the board and `intake.jsonl`'s record count does not move. So
+one of the three names USER-906 put in the invariant never exercises its
+permission. Spec verification item 7 says *"`resolve-intake` and `intake-sweep`
+reduce the count"* — of those two, only `intake-sweep` does.
+
+**Whose mistake is it? Neither's.** USER-906's list is a *permission* list, not a
+prediction: it names the commands that are ALLOWED to remove records. In today's
+implementation discharge and removal are two commands — `resolve-intake` marks
+the outcome, `intake-sweep` takes discharged rows off the board — so the
+permission is simply unused. The command is right as written (the cleared/
+discharged row staying visible is a deliberate rule this repository states in
+`cmd_risk_clear` and `modes/queue.md`), and the permission is right as granted:
+if discharge and sweep were ever merged, the list would already be correct.
+
+**I did not adjust `SHRINK_ALLOWED` to match the finding.** All three names are
+still there. `test_resolve_intake_is_not_blocked_and_does_not_in_fact_shrink`
+asserts `rc == 0` **and** that the count is unchanged — the test records that
+the allowance is unused rather than pretending it fires — and the constant's own
+comment in `bin/perry-task` says the same thing at the declaration.
+
+## 7. The two converted tests, and why each had to be
+
+Both asserted the behaviour this row exists to change. Neither was "adjusted to
+pass".
+
+**`tests/test_asks_store.py`** — `test_the_ordinary_writer_still_writes_the_section_and_that_is_drift`
+→ `test_the_ordinary_writer_reaches_the_store_and_leaves_no_drift`.
+Its own docstring names this row as the thing that would convert it:
+
+> **Deliberately not converted (TASK-203).** `perry-task answer` writes the
+> board and not the store, exactly as `risk-add` and `perry-task intake` still
+> do. Converting one register's writers alone would make an ordinary command
+> mint a store as a side effect on a project that never ran the gated import.
+> What the store adds today is that the divergence is REPORTED rather than
+> silent — which is this assertion.
+
+TASK-203 is the row that converts all three registers at once, which is the
+condition that docstring set. The assertion is now the other half of the same
+fact — `drifted == 0` — **plus** two the old test did not make: that the record
+carries the answer text, and that `answered` is `True`. The drift READING is not
+lost: it belongs to a hand edit, and the other four tests in
+`TestDriftIsReportedRatherThanAbsorbed` edit `BOARD.md` directly and still make
+it.
+
+**`tests/test_intake_store.py`** — `test_a_sweep_moves_n_and_the_store_is_what_says_so`,
+name unchanged. It asserted `intake_store_drift.drifted == 3` after a sweep and
+then ran the import to fix it. `intake-sweep` now writes the store inside the
+same transaction as the board, so the renumbering is recorded as it happens and
+there is no window in which the two disagree. The reading the test exists for is
+unchanged and still asserted — `before[2] != after[2]`, *"n = 2 is a different
+row"* — and two assertions were added: the stored requests are the two survivors
+in order, and their `order` values are `[0, 1]`. The drift half belongs to a
+hand edit, and `test_a_row_deleted_by_hand_reports_every_row_it_renumbered`
+thirty lines up is where it is proved.
+
+## 8. Mutations
+
+**The harness.** `scratchpad/t203r4/mutate.py`, run against the tip `70dfa96`.
+Each mutation is anchored **by line number**, the exact old text is asserted to
+start at that line before anything is replaced (an anchor miss aborts the whole
+run and prints what it found), every `__pycache__` under the repo is cleared
+before and after, the harness sleeps past the next whole second because CPython
+validates a cached `.pyc` on mtime-in-whole-seconds plus size, and the file is
+restored and re-checked by `md5`. Every line below carries `[restored, md5 ok]`
+from that check. Anchors were re-derived at the tip and each is asserted
+**unique** in the file.
+
+Modules run per mutation: `test_register_store_invariant` (39),
+`test_intake_store` (50), `test_asks_store` (42), `test_purge` (47) = **178**,
+which is the number in every `Ran` line below. The full suite was not re-run per
+mutation; a mutation that reddens a test in a module not listed would not have
+been seen.
+
+**Two harness runs before this one are discarded, not reported.** The first was
+killed mid-mutation by a foreground timeout and left the tree dirty. The second
+had **two instances of my own harness running against the same worktree at
+once** — each took the other's mutation as its `original`, so restores wrote
+mutants back and red sets included tests that a mutation could not touch. That
+is what produced the six "successful write" failures I flagged earlier as
+possible load flakes. They were not flakes and they were not load: **they are
+M10's red set** — `test_a_row_replaced_by_hand…`,
+`test_ask_and_risk_add_reach_their_stores_too`,
+`test_intake_on_a_project_with_no_store…`,
+`test_intake_sweep_may_shrink_the_intake_store`,
+`test_resolve_intake_is_not_blocked…` and
+`test_the_lint_prints_a_drift_verdict…`. One harness had M10 applied to the file
+while the other ran the tests, and the result was attributed to M1, M2, M3 and
+M5 in turn. A control run on the same tree was green throughout, which is what
+said the tree was fine and the harness was not.
+
+The harness now refuses to start if another instance has this directory as its
+cwd, or if the worktree is dirty. Both refusals fired in practice: the dirty
+check caught a tree left mutated by the killed run and printed the anchor it
+expected against the `if True:` it found.
+
+Every line below is the harness's own output. `[restored, md5 ok]` is the
+harness asserting the file came back byte-identical.
+
+| # | anchor | what it changes | result |
+|---|---|---|---|
+| **M1** | `bin/perry-task:2215` | `if after >= before or event_name in SHRINK_ALLOWED:` → `if True:` — **the invariant deleted** | 23 failures / **12 named tests**: all four doors, all four reproduction tests, both boundary unit tests, and `test_commit_asks_the_invariant_about_tasks_jsonl` |
+| **M2** | `bin/perry-task:2179` | `SHRINK_ALLOWED = frozenset({...})` → `frozenset()` | 21 named tests, **14 of them in `test_purge`** — `perry-task purge` refuses end-to-end. Also `test_intake_sweep_may_shrink_the_intake_store` and the converted `test_a_sweep_moves_n_and_the_store_is_what_says_so` |
+| **M3** | `bin/perry-task:2627` | the `tasks.jsonl` call site → `pass` | **1**: `test_commit_asks_the_invariant_about_tasks_jsonl`. Before `70dfa96` this was **0** — § 6 |
+| **M4** | `bin/perry-task:2215` | `after >= before` → `after > before` — the boundary off by one | 49 named tests. Every equal-count write refuses; the boundary is load-bearing, and `test_growing_and_holding_steady_are_both_fine` is the unit test that says so |
+| **M5** | `bin/perry-task:2317` | the uniqueness clause → `if False:` | **1**: `test_a_repeated_identity_is_no_identity_even_when_no_two_are_adjacent` |
+| **M6** | `bin/perry-task:2317` | uniqueness → **consecutive-only** (`any(a == b for a, b in zip(ids, ids[1:]))`) | **1**: the same test. Round 3 measured this exact weakening as **green across all 2815 tests**; the distinction it said could not be made is now made |
+| **M7** | `bin/perry-task:2321` | the positional identity check → `if False:` | **1**: `test_a_row_replaced_by_hand_does_not_hand_its_discharge_to_the_newcomer` — the case the invariant cannot see (§ 5) |
+| **M8** | `bin/perry-task:2257` | `except json.JSONDecodeError` → `except ZeroDivisionError` — the traceback escapes again | **1**: `test_a_corrupt_line_in_a_register_store_is_a_refusal_not_a_traceback` |
+| **M9** | `bin/perry-task:2352` | the shape early-return moved **above** `refuse_to_shrink` — **round 2/3's architecture, rebuilt** | 8 failures / **2 named tests**: `test_door_three_no_section_shape_on_any_register_may_empty_a_present_store` and `…the_foreign_shape_is_refused_on_every_register`. The ORDER is the fix, and it is tested |
+| **M10** | `bin/perry-task:2714` | `if register:` → `if False:` — the register store leaves the canonical set | 8 named tests: every "the write reaches its store" test, including **both converted tests** |
+| **M11** | `bin/perry-task:2151` | `"add": "intake"` removed from `REGISTER_EVENTS` | 8 named tests: the whole reproduction, doors 1 and 2, and `test_the_two_task_events_that_touch_intake_are_declared` |
+| **M12** | `bin/perry-task:7239` | the success line back to the flat `"store + journal"` template | **1**: `test_the_success_line_names_the_register_store_only_when_one_is_written` |
+
+**Twelve mutations, twelve reddened a named test. None was green.** All twelve
+printed `[restored, md5 ok]`, and the worktree is clean at `70dfa96` with
+`bin/perry-task` matching its committed blob (`a9af2381b6835ce702629ef5ac23c2b8`).
+
+Three of them are worth reading twice:
+
+- **M6** is round 3's own counter-example. It said a guard tripping only on
+  *consecutive* equal identities was green across all 2815 tests, so the shipped
+  test could not tell uniqueness from adjacency. Here it reddens one named test
+  and nothing else.
+- **M9** rebuilds **round 2/3's architecture** — the shape gate consulted before
+  the invariant, so an unreadable section silently skips the write instead of
+  refusing. It reddens both door-3 tests. The ORDER of those two lines is the
+  fix, and the order is tested.
+- **M3** is the finding in § 6: 0 red before `70dfa96`, 1 red after.
+
+## 9. Baselines — the runner, the tree, and the load
+
+Runner: `bash tests/run`. Tree: the worktree
+`…/5b3ba585-…/scratchpad/wt-203-new`. `test_diagnose`'s queue-register test
+reconciles against the LIVE board, so a worktree carrying different intake rows
+gives a different number; this worktree carries `main`'s at `6c0d041`.
+
+| tree | commit | modules | tests | failures | load avg while measuring |
+|---|---|---|---|---|---|
+| before | `6c0d041` (`main` at fork) | 98 | 2882 | 3 | ~1 (machine quiet) |
+| after | `b09776d` (the invariant) | 99 | 2919 | 3 | 34 |
+| **tip** | **`70dfa96`** | **99** | **2921** | **3** | **34–48** |
+
+The tip is the number that describes what ships. The load figure is stated
+because a number measured at load 48 with the condition named is usable and the
+same number without it is not: seven agent sessions were running concurrently on
+this machine, and the suite took 498s against 343s on the quiet run.
+
+The failure **set** is byte-identical in all three:
+
+- `test_diagnose.TestUserLoadFindings.test_perry_itself_passes_its_own_id_checks`
+- `test_diagnose` … `test_the_queue_register_reconciles_with_the_queue_on_this_repository`
+- `test_kr_progress_provenance.TestBothOfTodaysWrongReadingsFlip.test_no_current_in_the_payload_claims_to_be_a_measurement`
+
++1 module and +39 tests are `tests/test_register_store_invariant.py`.
+**This change adds no failure.** `main` at `6c0d041` reproduces the `70eae67`
+figure the spec quotes (98 / 2882 / 3), so the branch is measured against the
+number the spec names.
+
+### One flake, recorded rather than explained away
+
+On the first post-fix full run,
+`test_host_support.TestOpenCodeDispatchLimit.test_concurrent_mixed_registers_do_not_exceed_global_cap`
+failed `2 != 3`. It did not appear in the before run, did not appear in the
+second post-fix full run, and passed 3/3 in isolation. It exercises
+`bin/perry-dispatch-limit`, a bash script this change does not touch, under
+8-way parallel load on a machine at load average 34. I am recording that it
+appeared once; I am not claiming to have diagnosed it.
+
+## 10. What I did NOT do, and what I could not verify
+
+1. **The full suite was not re-run per mutation.** Each mutation ran four
+   modules (178 tests). A mutation that reddens something in one of the other 95
+   modules would not have been seen.
+
+2. **`python3 -m unittest discover -s tests` was not run on either tree.** The
+   spec notes the two runners disagree by 3 on this repository; I measured with
+   `bash tests/run` on both trees and did not run the discover form, so that
+   figure is neither confirmed nor used here. Spec verification item 5 asks for
+   it and I did not produce it.
+
+3. **A localized board was not exercised.** Round 3 verified the register code
+   against a `zh` board; I did not. `register_section_shape` delegates to
+   `perry_store`'s shape functions through `_ops()`, which is the i18n-aware
+   path, and `tests/run` step 4 lints `tests/fixtures/sample-project-zh` clean —
+   but no zh board was driven through a refusal.
+
+4. **Crash recovery and the transaction marker were not re-tested this round.**
+   The register store joins `replace_canonical_pair`'s canonical set, which
+   already stages an arbitrary number of entries and records every pre-image;
+   rounds 1 and 3 each exercised `os._exit(9)` at every rename boundary against
+   that same code, and this round changed neither the marker nor the staging. I
+   did not re-run that harness, so the claim rests on their measurements plus
+   the fact that the list this round appends to is the same list.
+
+5. **Concurrency between two Perry writers was not exercised**, and neither was
+   the `recover_stale_lock` TOCTOU round 3 named as a possible flake mechanism.
+
+6. **The refusal is now reachable in ordinary use, and that is a cost I did not
+   measure.** A project whose board and store have drifted — a hand-tidied
+   intake row, a renamed column, a `## Intake` section removed by `/pmo triage`
+   — will find the *next* write refused, including writes that have nothing to
+   do with that register. That is what option B asks for, and the refusal names
+   both recovery directions. I did not measure how often this repository's own
+   board is in such a state, and a reviewer may reasonably want that measured
+   before merge.
+
+7. **An unrelated `add` on a project with a healthy `## Intake` and no store
+   will now MINT `intake.jsonl`.** That is the row's goal (`claims[]` stores
+   that exist on disk, 4 of 6 → 6 of 6) and it is also a side effect of a
+   command that has nothing to do with intake. It is deliberate and it is the
+   behaviour round 1's own comment worried about; I am naming it rather than
+   leaving it to be discovered.
+
+8. **`perry-lint`'s census coverage is TASK-209 and is untouched.** What this
+   round changes is what the census SAYS on a store that was about to be
+   truncated: `intake store: 0 record(s), 0 row(s) drifted` becomes
+   `3 record(s), 3 row(s) drifted`, because the records are still there.
+
+9. **`asks.jsonl` is in scope and is written**, per the amendment. The original
+   spec's "Out of scope" line is superseded and no follow-up row is proposed,
+   because there is nothing left to follow up.
+
+10. **The board and `perry/tasks.jsonl` were not touched.** The PMO owns those.
+    `main` advanced to `91e5351` (ADR-010, DESIGN-013) while this round ran;
+    `git merge-tree` reports no conflict — this branch touches `bin/perry-task`
+    and four test files and nothing else.
+
+## 11. Where this leaves the row
+
+- Spec verification items 1 and 2 hold: after `perry-task intake` on a project
+  with no `intake.jsonl`, the store exists and holds the row, `perry-lint`
+  prints a drift verdict rather than *"unchecked, not clean"*, and
+  `perry-tasks intake-diff` byte-compares clean —
+  `TestTheOrdinaryWriteReachesItsStore`.
+- Item 3 (mutation) is § 8; item 4 (the risks half) was answered by
+  `TASK-203-premeasurement.md` before this round and this round makes both
+  `risk-add` and `risk-clear` write their store.
+- Item 5 (`discover`) is **not done** — § 10.2.
+- The amendment's items 6 and 7 are § 3.
+- P003-O1-KR1 moves from 4 of 6 to 6 of 6 **for any project that runs one
+  ordinary register command**. It does not move for a project that runs none:
+  the store mints on first write, not on install. Nothing here writes to
+  `/Users/bytedance/proj/Perry`, so Perry's own count is unchanged until the PMO
+  runs a register command on `main`.
+
+## 12. Forward note — ADR-010
+
+`main` locked ADR-010 (*"BOARD.md stops existing; the board is what a command
+prints"*) while this round ran. The invariant is on the right side of it: it
+protects the STORES, which survive ADR-010, and every one of the four doors is a
+way the board could destroy a store. When `BOARD.md` goes, `register_change`'s
+derivation-from-the-board goes with it and `refuse_to_shrink` stays — it counts
+records, not rows.

+
+**FAIL.**
+
+The invariant is real, the twelve mutations are real, and the four known doors
+are genuinely closed. There is a **fifth door**, and it is the same defect the
+row has failed three rounds for: an ordinary-looking command silently truncates
+a canonical register store at exit code 0, with `perry-lint` reporting the wreck
+as `0 row(s) drifted`.
+
+The door is `SHRINK_ALLOWED`. The exemption is granted **per command name and
+without a bound** — a command on the list may shrink a store by any amount, for
+any reason, including a shrink it did not perform. `resolve-intake`, which the
+author's own § 6 finding 2 establishes *removes no record at all*, therefore
+carries an unbounded licence to destroy the whole store. The author's conclusion
+that the permission "is simply unused" is false: it is unused only on a board
+that has not drifted, and the drifted board is the entire subject of this row.

+
+**11781 bytes / 28 records → 1420 bytes / 4 records. Twenty-four canonical
+records destroyed, exit code 0, `perry-lint` clean.** Compare
+`TASK-203-merge-hold.md`: *8240 bytes / 24 records → 0, exit code 0,
+`0 error(s)`, `intake store: 0 record(s), 0 row(s) drifted`.* Same signature,
+same store, same repository, one command over.
+
+The same hole on `intake-sweep`, which shrinks **more than it swept** — again on
+this repository's own intake data, copied to scratch (the live board had grown
+to 31 intake rows by the time I ran this):
+
+```
+minted from BOARD.md                                31 records / 13643 bytes
+perry-task resolve-intake 2 …                       31 records   (legitimate discharge)
+# 25 rows hand-tidied off `## Intake`; 6 remain, one of them the discharged row
+perry-task intake-sweep    rc=0  "wrote 1 row(s) (intake-sweep) → … intake.jsonl …"
+                                                     5 records / 1770 bytes
+perry-lint:  0 error(s) · intake store: 5 record(s), 0 row(s) drifted
+```
+
+It reports sweeping **one** row and removes **twenty-six** records. `purge` on
+`tasks.jsonl` is not exposed the same way, because `commit()` builds `records`
+from `current` and can shorten it by at most one.
+
+### Why this is a defect and not the spec working as written
+
+The amendment says *"Only an explicit removal command — `purge`,
+`resolve-intake`, `intake-sweep` — may reduce a record count."* Read as a bare
+membership test, the implementation obeys it. But the sentence the amendment is
+enforcing is the one above it — *"An ordinary write may never SHRINK a canonical
+store"* — and the shrink above is not the removal `resolve-intake` was permitted
+for. `resolve-intake` removes nothing. Every record it destroyed here is a
+record the command never touched, on rows it never addressed.
+
+The list is a permission to remove **what the command removes**, not a permission
+to persist whatever the board happens to derive to. The fix is still a count, not
+a fifth predicate and not option A: an allowed command may shrink by exactly the
+number of records it removed (`resolve-intake` 0, `intake-sweep` the rows it
+swept, `purge` 1) and `refuse_to_shrink` refuses the rest. That stays inside
+option B — it asks nothing about the command, the identity or the board, only
+whether the drop in the count is the drop the caller declared.
+
+### The suite cannot see it, and I measured that too
+
+My own mutation (`MR`, `bin/perry-task:2179`): remove **only** `"resolve-intake"`
+from `SHRINK_ALLOWED`, leaving `purge` and `intake-sweep`. Across the four
+modules the author mutated (178 tests):
+
+```
+RED(2): test_each_of_the_three_named_commands_may_shrink
+        test_the_allowlist_is_exactly_the_three_commands_user_906_named
+        [restored, md5 ok]
+```
+
+Both are assertions about the constant — one is a direct unit call on
+`refuse_to_shrink("intake", …, "resolve-intake", 3, 0)`, the other compares the
+frozenset to a literal. **No behavioural test depends on `resolve-intake` being
+allowed to shrink**, because the one behavioural test,
+`test_resolve_intake_is_not_blocked_and_does_not_in_fact_shrink`, runs on a
+**clean** board (`self.fixture(build_board())`) where no shrink is possible. It
+asserts `rc == 0` and `len(records) == 4` — which is true whether the allowance
+exists or not. The test the author offers as the record that "the allowance is
+unused" is precisely the test that cannot tell.
+
+The suite gets one line away from the defect and stops.
+`tests/test_intake_store.py § test_a_row_deleted_by_hand_reports_every_row_it_renumbered`
+builds the exact precondition — a `## Intake` row deleted by hand against a
+minted 4-record store — and then runs only `perry-lint`. Its own docstring says
+*"deleting the first row really does mean `resolve-intake 2` now addresses what
+`resolve-intake 3` addressed yesterday"*. Nothing in the suite then runs
+`resolve-intake` on that board.
+
+---
+
+## 2. Rulings on the three declared gaps
+
+**Gap 1 — the `tasks.jsonl` call site proves wiring, not reachability. RULING:
+KEEP the two lines.** The author's own framing is right and the mutation numbers
+back it (M2 reddens 14 `test_purge` tests through the CLI, so the site is
+reached; M3 reddens exactly one test, and only since `70dfa96`). A monkeypatch-
+only *refusal branch* on a guard whose *call* is exercised end-to-end is not the
+TASK-095 shape — TASK-095's guard was never reached at all. The state is
+unreachable today only because `load_task_records` refuses a duplicate id first;
+that is a second guard, not an argument for deleting the first, and `commit()`'s
+task branch is exactly the code a future edit breaks silently. The test's own
+docstring says what it does and does not claim, which is the honest form. This
+does not block.
+
+**Gap 2 — `resolve-intake` holds a permission it never exercises. RULING: this
+is the blocking defect.** It is not latent and the permission is not unused: § 1
+above uses it to destroy 24 canonical records on this repository's own intake
+data. The author reasoned about the allowance on a clean board, wrote a test on
+a clean board, and did not try it on the drifted board that is this row's whole
+subject. An unbounded name-keyed exemption inside a security-shaped invariant is
+a hole, and here it is a reachable one on the single most routine triage command
+in the register.
+
+**Gap 3 — nobody measured how often a real board sits in the drifted state that
+now refuses the next write. RULING: measured, and it does NOT block.** On
+`/Users/bytedance/proj/Perry` as of 2026-08-30 (state copied to scratch):
+`risks.jsonl` is 4 records at **0 drift**; `intake.jsonl` and `asks.jsonl` **do
+not exist**, so the first ordinary write mints rather than refuses. All three
+ordinary register writes come back clean on the live board copy:
+
+```
+risk-add --dry-run   rc=0  "would write RX-005 (risk-add) → … risks.jsonl …"
+intake   --dry-run   rc=0  "would write the row (intake) → … intake.jsonl …"
+ask      --dry-run   rc=0  "would write USER-910 (ask)  → … asks.jsonl …"
+```
+
+I also confirmed the refusal cannot arm itself: an ordinary command re-renders
+the board without dropping register rows (`add`, `risk-add`, `ask` each left
+`## Intake` at 4 rows / 4 records). The drifted state needs a hand edit, a
+triage pass or a merge — which is real, and documented, but is not the ambient
+condition of an ordinary board. This is not TASK-095 round 5's mistake. It would
+have been worth stating in the RESULT; it is not a reason to hold the row.
+
+---
+
+## 3. What I verified, and the numbers
+
+Everything below was run on **copies** of the reviewed worktree
+(`scratchpad/rjv4-203r4/{tree,mut,at-762bee1,at-b09776d,liveboard,repro}`),
+never in `scratchpad/review-203r4` and never against
+`/Users/bytedance/proj/Perry`. No `git checkout`/`stash`/`reset`/`clean` was run
+anywhere. No write-side Perry tool touched the repository; the only write-side
+runs were against copied state in `$TMPDIR`.
+
+*Disclosure*: invoking `review-203r4/bin/perry-task` against those copies caused
+CPython to write `review-203r4/bin/__pycache__/*.pyc`. No source file in the
+reviewed tree was modified — `git status --porcelain` in `review-203r4` is empty
+— and I left the caches in place rather than deleting files under another
+agent's running suite.
+
+### Claim 1 — the merge-hold reproduction is refused now. **VERIFIED.**
+Queue-mode track, `## Intake` deleted from the board, store at 4 records:
+
+```
+add --track ops   rc=1  refused — `add` would take …/intake.jsonl from 4
+                  record(s) to 0 …    store unchanged, 744 B, md5 unchanged
+perry-lint:       1 error(s), 6 warning(s) · intake store: 4 record(s), 4 row(s) drifted
+```
+
+The store survives and lint reports the drift instead of blessing the wreck.
+Same scenario on the live-board copy: refused at 28 records.
+
+### Claim 2 — step 1 deliberately RED, step 2 green. **VERIFIED, and red for the right reason.**
+Built by extracting `762bee1` / `b09776d` with `git show` into plain directory
+copies (no checkout):
+
+```
+at-762bee1/tests $ python3 -m unittest test_register_store_invariant
+Ran 37 tests — FAILED (failures=24, errors=7)
+at-b09776d/tests $ python3 -m unittest test_register_store_invariant
+Ran 37 tests — OK
+```
+
+The red set is the doors, not an unrelated breakage — 12 door-3 cells, 4
+door-3-foreign cells, 3 door-4, door 1, door 2, the reproduction, and 7 errors
+that are `refuse_to_shrink` not existing yet. The merge-hold test itself is red:
+`test_an_ordinary_add_on_a_queue_track_cannot_empty_a_present_intake_store`, and
+its failure message is the write succeeding
+(`wrote TASK-001 (add) → tasks.jsonl + intake.jsonl …`) rather than refusing.
+
+### Claim 3 — twelve mutations. **SPOT-CHECKED SIX, all red, all md5-restored.**
+My own harness (`scratchpad/rjv4-203r4/rjv4_mutate.py`, uniquely named per the
+brief), anchored by line, old text asserted before replacement, `__pycache__`
+cleared and a >1 s sleep on both sides, file restored and md5-compared. Four
+modules per mutation = 178 tests, control green.
+
+| mutation | red |
+|---|---|
+| M1 `if True:` (invariant deleted) | 23 red / **12 named** — all four doors, all four reproduction tests, both boundary units, `test_commit_asks_the_invariant_about_tasks_jsonl` |
+| M3 `tasks.jsonl` call site → `pass` | **1** — `test_commit_asks_the_invariant_about_tasks_jsonl` |
+| M5 uniqueness → `if False:` | **1** — `test_a_repeated_identity_is_no_identity_even_when_no_two_are_adjacent` |
+| **M6 uniqueness → consecutive-only** | **1** — the same test. **Round 3's exact weakening, measured GREEN across 2815 tests then, is RED now.** Closed. |
+| M9 (my variant: shape early-return hoisted above the invariant) | 12 red / **8 named**, including both door-3 tests and doors 1, 2, 4. The ORDER is tested. |
+| MR (mine) — drop only `"resolve-intake"` from `SHRINK_ALLOWED` | **2, both assertions about the constant** — see § 1 |
+
+M1, M3, M5, M6 reproduce the author's counts exactly. My M9 is a variant of his
+(I kept a refusal inside the non-table branch; he removed it entirely), so it
+reddens more, not fewer.
+
+### Claim 4 — the four round-3 findings. **ALL FOUR FIXED.**
+1. **Vacuous foreign shape.** `test_door_three_the_foreign_shape_is_refused_on_every_register`
+   loops 3 registers × 2 foreign variants = 6 cells, and inside each cell asserts
+   the control `shape_of(board, ops)[0] == "foreign"` **before** asserting
+   `rc != 0` and `f.raw(store) == before`. `TestTheFixturesAreTheShapeUnderTest`
+   independently asserts all 15 fixtures are the shape they claim, and
+   `test_the_foreign_legend_lands_inside_the_named_section` asserts the legend
+   text is inside the named section's body — the precise round-3 defect, as a
+   fact about text. Real on each of the three registers.
+2. **Uniqueness vs adjacency.** Closed — M6, above.
+3. **`JSONDecodeError` escaping.** Probed live: corrupt line 3 of `intake.jsonl`,
+   then `perry-task intake` → `rc=1`, no `Traceback` in the output,
+   `perry-task: refused — …/intake.jsonl line 3 cannot be read as JSON
+   (Expecting value). … nothing was written.`
+4. **Dead `section` parameter.** Gone; the function is
+   `register_section_shape(board, key)`, both arguments read, heading looked up
+   from `REGISTER_SPEC`.
+
+### Claim 5 — baselines. **PARTLY VERIFIED.**
+Runner `bash tests/run`. Tree: my copy of the reviewed worktree at `afb3a48`,
+whose `perry/` state is `main` at `6c0d041` — **that is the board state my
+numbers were taken on**, which is why the `test_contract_key_parity` witness
+tests the brief warns about do not appear here.
+
+```
+99 modules · 2921 tests · 446.8s · 8 workers · 2 module(s) red · 3 failures
+  test_diagnose  (2)  — test_perry_itself_passes_its_own_id_checks  (dangling
+                        ACTION-7, ADR-010, D009-1, D010-2, …) and the queue-
+                        register reconciliation
+  test_kr_progress_provenance (1) — test_no_current_in_the_payload…
+```
+
+Exactly the author's tip figure (99 / 2921 / 3) and exactly his failure set.
+Machine was loaded throughout (three other agents' suites running concurrently).
+I did **not** re-measure `6c0d041` at 98 / 2882 / 3.
+
+### Spec item 5 — `python3 -m unittest discover -s tests`. **RUN, on BOTH trees. Clean.**
+The author did not produce this figure. I ran it serially on the tip copy and on
+a reconstructed `6c0d041` fork-point tree (new module removed, `bin/perry-task`
+and the two converted test files reverted via `git show`, no checkout):
+
+| tree | tests | red |
+|---|---|---|
+| `6c0d041` (fork point) | 2875 | 8 |
+| tip `afb3a48` | 2914 | 9 |
+
+`+39` tests is exactly `tests/test_register_store_invariant.py`. The tip's red
+set is the fork point's **eight, unchanged**, plus one:
+`test_host_support.TestOpenCodeDispatchLimit.test_concurrent_registers_do_not_exceed_opencode_cap`
+— the load-sensitive `perry-dispatch-limit` bash flake the author already
+recorded in his § 9, on a script this branch does not touch, and the machine
+was carrying three other agents' suites while I measured.
+
+**This change adds no failure under either runner.** The six failures that
+separate `discover` from `bash tests/run` are pre-existing runner artifacts,
+now proven so on the fork point rather than assumed:
+
+- `test_store_is_canonical` and `test_task_summary` — `ModuleNotFoundError: No
+  module named 'tests'` from `from tests.X import …`, which is literally row 1
+  of this repository's own `## Intake` (filed 2026-08-21);
+- three `assertIs` identity failures in
+  `test_risks_store.TestTheReadersAreOneFunction` — `parsers` loaded twice under
+  two module identities, so `PT.is_risk_header is P.is_risk_register_header`
+  fails while the objects compare equal. I separately confirmed the branch's new
+  module does not cause these: `test_register_store_invariant` +
+  `test_risks_store.TestTheReadersAreOneFunction` run together is green, as is
+  the pre-existing `test_md_store` + the same class;
+- the `test_host_support` flake above.
+
+Spec item 5 is satisfied and it is clean.
+
+### Guards that survive their own deletion
+Beyond the twelve the author mutated, the one I found is `MR` above: the
+`"resolve-intake"` entry of `SHRINK_ALLOWED` has no behavioural test. That is
+not merely an untested guard — it is the defect.
+
+### New tests green for the wrong reason
+Checked all the known modes and found none:
+- boards parsing zero rows — `TestTheFixturesAreTheShapeUnderTest` asserts
+  4/4/3 records on the built board and on the minted stores before anything else
+  is claimed;
+- `"tasks.jsonl"` / `"asks.jsonl"` substring — the store names are looked up
+  from the `REGISTERS` table by exact filename, never matched as substrings of
+  output;
+- the conformance gate refusing first — fixtures write `GATE_OFF` (advisory);
+  I confirmed the gate's message appears as a *warning* on runs that succeed at
+  rc 0, so it is not what produces the refusals;
+- legend under `## Top risks` — now asserted against, twice;
+- a duplicate-Request test tripping the positional check first — the door-2 test
+  and the `carry_forward` unit test both carry explicit control assertions, and
+  M6 proves the distinction is made.
+
+The one test I judge misleading is
+`test_resolve_intake_is_not_blocked_and_does_not_in_fact_shrink` — not green for
+a wrong reason, but green on a board that cannot exercise the thing its
+docstring claims to record (§ 1).
+
+---
+
+## 4. Structural verdict on the invariant itself
+
+**It is not a fourth predicate, and the author's argument for that is sound.**
+`refuse_to_shrink` asks one question about two integers. The four known doors
+are closed by it and I could not construct a fifth *inside* it:
+
+- `register_change` is the only register-store writer in `bin/perry-task`
+  (`bin/perry-tasks`' `*-write --from-board` importers are the sanctioned
+  explicit direction and are out of scope by the spec);
+- the guard is applied to `len(derived)` and the write is `store_text(records)`
+  — I checked `intake_records` and confirmed `records` and `derived` always have
+  the same length, since a `current` merge fills fields per row and never drops
+  one, so the guard counts the number actually written;
+- the guard runs before the shape early-return, before validation and before
+  anything is staged, and M9 shows the order is tested;
+- an ordinary re-render does not itself drop register rows, so the guard cannot
+  be armed by Perry's own writes.
+
+The fifth door is not in the invariant. It is in the exemption, which is a
+name-keyed, unbounded bypass **around** the invariant — the one place round 4
+kept round 1's shape, on the user's instruction, without bounding it.
+
+---
+
+## 5. Not checked
+
+1. `6c0d041` under **`bash tests/run`** (98 / 2882 / 3) not re-measured — I
+   measured the tip under that runner, and both trees under `discover`.
+2. Six of the twelve mutations (M2, M4, M7, M8, M10, M11, M12) were not
+   re-run; I spot-checked six including all three the brief singled out.
+3. Full suite not re-run per mutation — same limitation the author declares.
+4. Crash recovery / `os._exit(9)` at the rename boundaries not re-tested.
+5. Localized (`zh`) board not driven through a refusal — same as the author's
+   § 10.3.
+6. Concurrency between two Perry writers not exercised.
+7. `asks.jsonl` and `risks.jsonl` were exercised only through the shape matrix
+   and the fixture writes. They are **not** exposed to § 1: `SHRINK_ALLOWED`
+   holds `purge` (tasks), `resolve-intake` and `intake-sweep` (both intake), so
+   no command may shrink the ask or risk store at all. The blast radius of the
+   defect is `intake.jsonl`, which is the register this row's merge-hold
+   measurement was taken on and the one the PMO writes most.
+
+---
+
+## 6. What would clear this
+
+One change and one test:
+
+- bound the allowance — an allowed command may shrink by exactly the count it
+  declares removing, and `refuse_to_shrink` refuses any excess. `resolve-intake`
+  declares 0, so it can no longer shrink at all; `intake-sweep` declares the rows
+  it swept; `purge` declares 1;
+- and the test that fails without it: the § 1 sequence, on each shrink-permitted
+  command — a drifted board, an allowed command, and the assertion that the
+  records it did not touch are still on disk.
+
+Rounds 1–3 each closed one door and left another. This round closed four and
+left the exemption unbounded.

+## 0. What round 4 got wrong, in one sentence
+
+The invariant was sound — the reviewer could not break `refuse_to_shrink` from
+inside, and all four known doors stayed closed. `SHRINK_ALLOWED` was not: it
+granted its exemption **by command name and without a bound**, so a listed
+command could shrink a canonical store by any amount, **including a shrink it
+did not perform**.
+
+## 1. Commits
+
+| commit | what it is |
+|---|---|
+| `36be5bd` | the three bounded-exemption tests, on boards where a shrink is possible. **Deliberately RED.** |
+| `1e42b97` | the bound: an allowed command may shrink by exactly the count it declares removing. |
+| `a900585` | a guard in `declared_removal` that nothing could reach, removed. |
+| `0cc3889` | the line `tests/test_intake_store.py` stopped one short of: the dangerous state it builds now has a shrink-permitted command run on it. |
+| `0ef1576` | the shared control gets the `assertLess` that makes "a clean board fails its own control" true of the code as well as the prose; the wrong `discover` attribution is struck. |
+
+## 2. The rule as implemented
+
+`bin/perry-task`, two names and one comparison:
+
+```python
+SHRINK_ALLOWANCE: dict[str, int | str] = {
+    "purge": 1, "resolve-intake": 0, "intake-sweep": "count",
+}
+
+def declared_removal(event: dict) -> int:
+    rule = SHRINK_ALLOWANCE.get(event.get("event") or "")
+    if rule is None:
+        return 0
+    if isinstance(rule, int):
+        return rule
+    count = event.get(rule)
+    if not isinstance(count, int) or isinstance(count, bool) or count < 0:
+        return 0
+    return count
+
+def refuse_to_shrink(store, path, event: dict, before, after, why="") -> None:
+    allowed = declared_removal(event)
+    if before - after <= allowed:
+        return
+    raise Refused(...)
+```
+
+**An allowed command may shrink by exactly the count it declares removing.**
+
+| command | declares | why |
+|---|---|---|
+| `purge` | `1` | it removes the one task it names, and `commit()`'s removal branch is `[r for r in current if r["id"] != removed_id]` |
+| `resolve-intake` | `0` | it rewrites one `Outcome` cell. Round 4's own § 6 finding 2 established that it removes no record; the bound is that finding, enforced |
+| `intake-sweep` | `"count"` | the rows it swept — `cmd_intake_sweep` already carries `count: len(discharged)` on its event, so nothing new is minted to make the bound readable |
+
+Three properties this has that the frozenset did not:
+
+1. **It is still one question about two integers.** Not "may this command
+   shrink" but "is the drop the drop the caller declared". Nothing is asked
+   about the board, the section's shape, the identity of a row, or when the
+   gate is read. **Option A stays rejected** and stays unnecessary: WHEN you
+   look does not change HOW MANY there are, and now neither does WHO is
+   looking.
+2. **The bound cannot be forgotten at a call site.** `refuse_to_shrink` takes
+   the EVENT rather than the event name and computes `declared_removal` itself.
+   There is no signature that carries the permission without the number.
+3. **It fails closed.** A command nobody named declares 0. A listed command
+   whose count is missing, negative, a `bool` or not an `int` declares 0 too —
+   an unreadable declaration is a refusal, never a licence. The frozenset
+   treated the NAME as the permission, so a sweep whose count went missing
+   would still have been allowed to remove everything.
+
+The two call sites are unchanged in number and position:
+
+| store | call site | what it counts |
+|---|---|---|
+| `tasks.jsonl` | `commit()` — `bin/perry-task:2695` | `len(current)` vs `len(records)` |
+| the three registers | `register_change()` — `bin/perry-task:2419` | records on disk vs records derived |
+
+### The refusal now has two messages, because there are two failures
+
+An ordinary write keeps round 4's text. An explicit removal over its own
+declaration gets its own, naming both numbers:
+
+```
+perry-task: refused — `resolve-intake` would take …/perry/intake.jsonl from 30
+record(s) to 4 — a drop of 26 — but `resolve-intake` removes 0 record(s). An
+explicit removal may shrink a canonical store by exactly what it removes and no
+more (USER-906). Nothing was written.
+If the board is right and the store is stale, the explicit board-to-store
+direction is `perry-tasks intake-write --from-board`; if the store is right,
+`perry-tasks intake-render --write` puts the records back on the board.
+```
+
+## 3. The defect, reproduced and closed on this repository's own data
+
+Both reproductions were run **side by side**: the same drifted state built
+twice, driven once by round 4's tip (`bin/perry-task` md5
+`a9af2381b6835ce702629ef5ac23c2b8`, extracted from `afb3a48` with `git archive`
+— no checkout) and once by this branch's tip (md5
+`f282d2395f1eae6c5fa077f3e11f958a`). State is `cp -R` of
+`/Users/bytedance/proj/Perry`'s `.perry/` and `perry/` as of 2026-08-30, minted
+with the gated `perry-tasks intake-write --from-board` at **13041 bytes / 30
+records / md5 `61eece8755d571c838d417e5439d63e5`**, then 26 of the 30 `##
+Intake` rows tidied off `BOARD.md` by hand — the `/pmo triage` state.
+
+### `resolve-intake` — the V4 review's § 1
+
+| | round 4 (`afb3a48`) | round 5 (`a900585`) |
+|---|---|---|
+| rc | **0** | **1** |
+| line | `wrote intake row 1 (resolve-intake) → …` | `refused — … a drop of 26 — but resolve-intake removes 0 record(s)` |
+| store after | **1431 bytes / 4 records** | 13041 bytes / 30 records, **md5 unchanged** |
+| `perry-lint` | `0 error(s)` · `intake store: 4 record(s), 0 row(s) drifted` | `0 error(s)` · `intake store: 30 record(s), 26 row(s) drifted` |
+
+**26 canonical records destroyed at exit code 0 with lint reporting the wreck as
+clean, versus a refusal and an honest drift count.** The left column is the
+signature of `TASK-203-merge-hold.md`.
+
+### `intake-sweep` — same board, one row discharged by hand first
+
+| | round 4 | round 5 |
+|---|---|---|
+| rc | **0** | **1** |
+| line | `wrote 1 row(s) (intake-sweep)` | `refused — … a drop of 27 — but intake-sweep removes 1 record(s)` |
+| store after | **1121 bytes / 3 records** | 13041 bytes / 30 records, **md5 unchanged** |
+| `perry-lint` | `intake store: 3 record(s), 0 row(s) drifted` | `intake store: 30 record(s), 27 row(s) drifted` |
+
+It reported sweeping one row and removed twenty-seven records.
+
+### The register still works — the whole intake lifecycle, on an in-sync copy
+
+A bound that also blocks the sweep has broken the register. On a live-board copy
+with the board and store in sync, driven only by this branch's tip:
+
+```
+start                                             30 records
+resolve-intake 1 --outcome dropped     rc=0    →  30 records
+intake-sweep                           rc=0    →  29 records
+intake --title 'an ordinary new request' rc=0  →  30 records
+perry-lint:  0 error(s), 4 warning(s) · intake store: 30 record(s), 0 row(s) drifted
+```
+
+## 4. The tests, and why they are not round 4's tests
+
+**Round 4's test for this allowance ran on a clean board.**
+`test_resolve_intake_is_not_blocked_and_does_not_in_fact_shrink` builds
+`self.fixture(build_board())`, where no shrink is possible, and asserts
+`rc == 0` and `len(records) == 4` — both true with the allowance and both true
+without it. The reviewer's mutation `MR` (drop only `"resolve-intake"` from the
+allowlist) reddened two tests, **both assertions about the constant**. The one
+test offered as the record that "the allowance is unused" is the one test that
+cannot tell. That test is kept, because it does say something — the invariant
+does not block the ordinary discharge — and its docstring now says exactly what
+it does and does not claim.
+
+`TestTheExemptionIsBounded` is the new class. **Every test in it runs on a board
+where a shrink IS possible, and asserts that as a control first**, through a
+shared `drifted()` helper that raises before any behaviour is asserted:
+
+```python
+self.assertEqual(len(f.records("intake.jsonl")), 4, "control: minted whole")
+tidy_intake_rows_off_the_board(f, keep)
+rows = len(board.section_rows("Intake"))
+self.assertEqual(rows, len(keep), "control: the board was tidied")
+records = len(f.records("intake.jsonl"))
+self.assertEqual(records, 4, "control: the STORE still holds every record")
+self.assertLess(rows, records,
+                "control: the board must hold FEWER rows than the store, or no "
+                "shrink is possible and this test cannot tell whether the bound "
+                "fired")
+```
+
+A clean-board version of any of these tests does not merely pass; it **fails its
+own control**. That is the structural answer to "a check that cannot fail on the
+thing it names".
+
+**That sentence was overstated when this document was first written, and the
+`assertLess` is what made it true.** The V4 round-5 review checked it and found
+that `drifted([1, 2, 3, 4])` — every row kept, no drift, no shrink possible —
+passed all three original controls, because nothing compared the two numbers to
+each other. The tests still went red, on their behaviour assertions, so nothing
+was green for the wrong reason and it was not a defect; but the claim was true
+of the prose and not of the code. Adding the assertion was cheaper than
+weakening the claim, and a probe confirms it fires:
+`AssertionError: 4 not less than 4 : control: the board must hold FEWER rows
+than the store …`. **A control that cannot fail is the same mistake as a test
+that cannot fail, one level up** — which is the mistake this whole row exists
+to stop repeating.
+
+| command | the named behavioural test | the board it runs on |
+|---|---|---|
+| `resolve-intake` | `test_resolve_intake_may_not_shrink_a_store_it_removes_nothing_from` | store 4 records, board 2 rows — 2 records at stake |
+| `intake-sweep` | `test_intake_sweep_may_not_shrink_by_more_than_the_rows_it_swept` | store 4, board 2 (one discharged) — it sweeps 1 and 3 were about to go |
+| `intake-sweep` | `test_intake_sweep_may_shrink_by_exactly_the_rows_it_swept` | in-sync board with **two** discharged rows — 4 → 2, so a bound written as the literal `1` is red |
+| `purge` | `test_purge_removes_the_one_record_it_names_and_leaves_the_other` | a two-record store — round 4's purge test ran 1 → 0, where "removed exactly one" and "removed everything" are the same number |
+| `purge` | `test_purge_may_not_take_two_records_with_one_removal` | a store carrying the subject's id twice |
+
+### The line the suite stopped one short of
+
+Separately from the class above, and the more useful of the two findings the
+round-4 review left on method rather than on code:
+`tests/test_intake_store.py § test_a_row_deleted_by_hand_reports_every_row_it_
+renumbered` **builds the exact dangerous state** — a hand-deleted `## Intake`
+row against a minted 4-record store, with a docstring that says outright that
+`resolve-intake 2` now addresses what `resolve-intake 3` addressed yesterday —
+and then runs only `perry-lint`. **Nothing in the whole suite then ran a
+shrink-permitted command on that board.** One more step is the entire defect.
+
+`0cc3889` extracts the board-building so both tests run on the same state, says
+in the lint-only test's docstring that it is deliberately lint-only and where
+the other question is asked, and adds
+`test_a_shrink_permitted_command_on_that_same_board_is_refused` to ask it.
+Mutation **MB1b** below confirms it is red under round 4's exact rule.
+
+**A test that constructs the dangerous state and then asserts something safe
+about it reads as coverage and is not.** That is the general lesson this round
+takes, and it is why `TestTheExemptionIsBounded.drifted()` asserts the danger
+before it asserts the behaviour.
+
+The last one is the one honest asterisk on this table and it is declared rather
+than smoothed over. `commit()`'s removal branch drops **every** record matching
+`removed_id`, so a duplicated id is a drop of 2 against a declaration of 1 — but
+`load_task_records` refuses a duplicate id before `commit()` ever sees one, so
+the state is constructed by replacing the loader for the duration of one
+`commit()` call, exactly as `test_commit_asks_the_invariant_about_tasks_jsonl`
+does. **It proves the declaration is what bounds the write; it does not claim
+the duplicate is reachable through the CLI.** The test's docstring says so. The
+reachable half of the purge bound is the row above it, and mutation MB6 below
+shows sixteen `test_purge` tests standing behind it end to end.
+
+Unit tests of `refuse_to_shrink` and `declared_removal` are kept in
+`TestTheInvariantItself`, and its docstring now says in its first line that
+assertions of that kind do not count on their own and why.
+
+## 5. Mutations
+
+Harness `scratchpad/r5b_mutate.py` — **uniquely named**, refuses to start on a
+dirty tree, refuses to start if another `r5b` lock exists in the worktree,
+anchors by line number, **asserts the old text is present before replacing it**,
+clears every `__pycache__` under `bin/` and `tests/` and sleeps past the whole
+second boundary on both sides, restores from an in-memory copy and compares
+`md5`. Every row below restored to md5 `36dc10b06465e7fd30573e61079cb264`
+(the file at `1e42b97`; the tip is `f282d2395f1eae6c5fa077f3e11f958a` after
+`a900585`, which is a comment-and-dead-guard change re-verified separately).
+
+Modules per mutation: `test_register_store_invariant`, `test_intake_store`,
+`test_asks_store`, `test_risks_store`, `test_purge` — **238 tests, control
+green** (239 from `0cc3889` onward).
+
+**MB1, MR and MB7 were each re-run at the shipped tip** (`f282d2395f1eae6c5fa07
+7f3e11f958a`, after `a900585` shifted the anchors by four lines) and reddened
+the same named tests, so the mutation evidence is about the file that ships and
+not only about the file at `1e42b97`.
+
+| mutation | anchor | change | red |
+|---|---|---|---|
+| **MB1** | `bin/perry-task:2269` | `if before - after <= allowed:` → `if after >= before or name in SHRINK_ALLOWANCE:` — **round 4's exact rule restored** | 12 failures / **6 named**, including all three new behavioural tests: `test_resolve_intake_may_not_shrink_a_store_it_removes_nothing_from`, `test_intake_sweep_may_not_shrink_by_more_than_the_rows_it_swept`, `test_purge_may_not_take_two_records_with_one_removal` |
+| **MB2** | `:2193` | `"resolve-intake": 0` → `99` | 3 / **`test_resolve_intake_may_not_shrink_a_store_it_removes_nothing_from`** + 2 unit |
+| **MB3** | `:2193` | `"intake-sweep": "count"` → `1` (a literal instead of the declared count) | 8 + 1 error / **`test_intake_sweep_may_shrink_by_exactly_the_rows_it_swept`**, `test_a_sweep_moves_n_and_the_store_is_what_says_so` + 3 unit |
+| **MB4** | `:2193` | `"intake-sweep": "count"` → `99` | 8 / **`test_intake_sweep_may_not_shrink_by_more_than_the_rows_it_swept`** + 3 unit |
+| **MB5** | `:2193` | `"purge": 1` → `99` | 4 / **`test_purge_may_not_take_two_records_with_one_removal`** + 3 unit |
+| **MB6** | `:2193` | `"purge": 1` → `0` | 17 failures + 4 errors / **21 named, 16 of them in `test_purge`** — `perry-task purge` refuses end to end — plus `test_purge_removes_the_one_record_it_names_and_leaves_the_other` and `test_purge_may_shrink_the_task_store` |
+| **MB7** | `:2214` | the fail-closed guard on `count` → `if False:` | 5 / **`test_a_declaration_this_tool_cannot_read_declares_nothing`** |
+| **MB9** | `:2419` | `register_change`'s call site passes `{}` instead of `event` | 5 / **`test_intake_sweep_may_shrink_the_intake_store`**, `test_intake_sweep_may_shrink_by_exactly_the_rows_it_swept`, `test_intake_sweep_may_not_shrink_by_more_than_the_rows_it_swept`, `test_resolve_intake_may_not_shrink_a_store_it_removes_nothing_from`, `test_a_sweep_moves_n_and_the_store_is_what_says_so` — the event reaches the gate |
+| **MB10** | `:2695` | `commit()`'s call site passes `{}` instead of `event` | 16 failures + 2 errors / **18 named, 16 in `test_purge`** |
+| **MR** | `:2193` | the reviewer's own: drop `"resolve-intake"` from the map entirely | **2 — and one of them is now `test_resolve_intake_may_not_shrink_a_store_it_removes_nothing_from`, a named behavioural test on a drifted board.** Under round 4 this mutation reddened only two assertions about the constant. This is the specific finding the round-4 review closed on |
+| **M1** | `:2269` | the invariant deleted — `if True:` | 34 failures / **17 named**: all four doors, all four reproduction tests, the three new bounded tests, `test_commit_asks_the_invariant_about_tasks_jsonl` |
+| **M6** | `:2384` | round 3's exact consecutive-only weakening of the uniqueness clause | **1 — `test_a_repeated_identity_is_no_identity_even_when_no_two_are_adjacent`.** Green across 2815 tests in round 3; still red here, so round 5's change did not re-open it |
+| **MB1b** | `:2273` | MB1 again, after `0cc3889`, against **239** tests | 13 / **7 named** — MB1's six plus **`test_a_shrink_permitted_command_on_that_same_board_is_refused`**, the line the suite had been stopping short of |
+| **MB1c** | `:2273` | MB1 again, after `0ef1576`'s `assertLess` control | 13 / **the same 7 named**, and `bin/perry-task` md5 unchanged at `f282d23…` — the tightened control changed the mutation evidence not at all, which is what a control that is not part of the subject should do |
+
+MB6 was interrupted once by a two-minute command timeout, leaving the mutation
+in the tree. It was restored by hand from the recorded old text and md5-verified
+back to `36dc10b06465e7fd30573e61079cb264` **before** it was re-run to
+completion; `git status --porcelain` was empty at that point. No `git checkout`,
+`stash`, `reset` or `clean` was run at any time in this round.
+
+There is no MB8: the mutation it would have been — deleting
+`not isinstance(rule, bool)` from `declared_removal` — reddens nothing, because
+`rule` is a literal in this file and nothing can reach that branch. The honest
+answer to a guard that survives its own deletion is to delete it, which is what
+`a900585` does; the guard that matters is the one on `count`, which arrives on
+the event and has MB7 behind it.
+
+## 6. Baselines — the runner, the tree, the board state, and the load
+
+**Runner:** `bash tests/run`, 8 workers.
+**Tree:** this worktree at `0ef1576`; an identical run at `0cc3889` gave the
+same figures, since `0ef1576` adds an assertion and not a test.
+**Board state:** `perry/` is `main` at `6c0d041` plus this row's round-4 and
+round-5 evidence files — i.e. the same board state round 4's numbers were taken
+on, which is why the two `test_contract_key_parity` witness tests the spec warns
+about (data-dependent on `conformance.in_progress_with_no_live_run` being
+non-empty on the LIVE board) do not appear in the red set here.
+**Load:** load average 8–15, from three other concurrent agent sessions.
+
+```
+99 modules · 2929 tests · 226.1s · 8 workers · 2 module(s) red
+  test_diagnose               (2)  test_perry_itself_passes_its_own_id_checks
+                                   + the queue-register reconciliation
+  test_kr_progress_provenance (1)  test_no_current_in_the_payload_claims_to_be_
+                                   a_measurement
+```
+
+**Round 4's tip was 99 modules / 2921 tests / 3 failures on this runner and this
+board state. This round adds 8 tests and no failures: 2921 + 8 = 2929, and the
+red set is identical, name for name.** None of the three is mine and none of
+them touches a register store. An earlier run at `0e6afd0`, before the eighth
+test landed, read 99 / 2928 / 3 with the same red set.
+
+### Spec item 5 — `python3 -m unittest discover -s tests`
+
+Run to completion this round, from the repository root, single-process, on this
+worktree at `0e6afd0` — one test before the tip, so 2928 rather than 2929:
+
+```
+Ran 2928 tests in 629.683s
+FAILED (failures=6, skipped=1)
+```
+
+The six, named:
+
+| failure | also red under `tests/run`? |
+|---|---|
+| `test_diagnose.test_perry_itself_passes_its_own_id_checks` | yes |
+| `test_diagnose.test_the_queue_register_reconciles_with_the_queue_on_this_repository` | yes |
+| `test_kr_progress_provenance.test_no_current_in_the_payload_claims_to_be_a_measurement` | yes |
+| `test_risks_store.TestTheReadersAreOneFunction.test_the_columns_are_one_list` | **no** |
+| `test_risks_store.TestTheReadersAreOneFunction.test_the_register_header_predicate_is_one_object` | **no** |
+| `test_risks_store.TestTheReadersAreOneFunction.test_the_bullet_and_placeholder_rules_are_one_object` | **no** |
+
+**The three-failure disagreement the spec names is these three, and they are
+runner artifacts on their face.** All three are `assertIs` identity assertions —
+`PT.RISK_COLUMNS is P.RISK_COLUMNS`, `PT.is_risk_header is
+P.is_risk_register_header` — and under a single-process `discover` the `parsers`
+module is imported twice under two identities (once through `bin/perry-task`'s
+own `sys.path` insertion of `bin/lib`, once directly by the test module), so two
+equal lists are not the same object: `['ID', 'Risk', 'Opened', 'Status'] is not
+['ID', 'Risk', 'Opened', 'Status']`.
+
+Measured, not assumed, two ways:
+
+* `test_risks_store` is **green under both runners in isolation, on this tree
+  and on a `git archive` copy of round 4's tip `afb3a48`** — 53 tests, OK, four
+  ways. It is the whole-tree single-process run that reddens them.
+* **`discover -s tests` was run to completion on the `afb3a48` copy too**, and
+  comes back `Ran 2921 tests`, `FAILED (failures=6, skipped=4)` — **the same six
+  failures, name for name.** So the three identity failures are not "look
+  pre-existing"; they are pre-existing, on round 4's tip, before any line of
+  round 5 was written. The seven-test difference (2921 → 2928) is this round's
+  tests, and the failure count does not move.
+
+**One unexplained discrepancy, recorded as unexplained.** The round-4 reviewer's
+own `discover` run reported `Ran 2914 tests`, `FAILED (failures=7, errors=2)`;
+neither of my runs reproduced the two `ModuleNotFoundError: No module named
+'tests'` errors or the `test_host_support` OpenCode-cap flake.
+
+An earlier draft of this document attributed the difference to tree layout — a
+`git archive` extraction versus a worktree. **That attribution was wrong and is
+struck.** The V4 round-5 reviewer ran `discover` on both a worktree copy and a
+`git archive` extraction and got my figures on **both**, with neither the
+`ModuleNotFoundError` nor the flake. So the layout is not the cause, and I do
+not know what is. Nothing is hidden by it — the six failures reproduce
+identically on this tip and on round 4's — and the difference has not been
+explained.
+
+**An unexplained difference recorded as unexplained is worth more than a
+plausible cause that turns out not to be the cause.** This project lost an hour
+to exactly that substitution the night before this round.
+
+## 7. What I did NOT do, and what I could not verify
+
+1. **The `tasks.jsonl` call site keeps its two lines and its monkeypatched
+   test.** The V4 round-4 review RULED on this — "KEEP the two lines", not
+   TASK-095's shape, does not block — and `test_purge_may_not_take_two_records
+   _with_one_removal` is a second test of the same constructed shape, added for
+   the same reason and declared the same way in § 4.
+2. **Refusal frequency on real boards.** RULED measured and non-blocking by the
+   round-4 review. Re-measured incidentally here: `main`'s `## Intake` now mints
+   30 records against a board with 30 rows and **no discharged row at all**, so
+   `intake-sweep` on the live board refuses for its own reason ("no discharged
+   intake rows to sweep") before the invariant is reached, and the ordinary
+   register writes come back rc 0 on an in-sync copy (§ 3).
+3. **The full suite was not re-run per mutation.** Five modules / 238 tests per
+   mutation, as in round 4, for the same reason.
+4. **Crash recovery at the rename boundaries was not re-tested** in this round.
+   The bound is evaluated strictly before anything is staged, so it does not
+   reach `replace_canonical_pair`, but I did not re-run round 4's `os._exit(9)`
+   probes.
+5. **A localized (`zh`) board was driven through a bounded refusal — by the
+   review, not by me.** The V4 round-5 reviewer closed this gap: `asks.jsonl`
+   with 2 records on the `zh` fixture, both rows hand-deleted, `perry-task ask`
+   → rc 1, store unchanged. Recorded as **verified by the review**, which is a
+   weaker provenance than verified here and is not the same as untested.
+6. **Concurrency between two Perry writers was not exercised.**
+7. **`asks.jsonl` and `risks.jsonl` remain unexposed to this defect by
+   construction** — no command declares a removal on either store, so no command
+   may shrink them at all. That is unchanged from round 4 and was not re-probed
+   beyond the shape matrix and the suite.
+8. **I did not re-measure `main` at `6c0d041`** (98 / 2882 / 3 under
+   `git archive`). My numbers are the branch tip only, on the board state named
+   in § 6.
+
+## 8. The door this bound does NOT close, named here so nobody reads § 3 as more
+
+**A count-preserving SUBSTITUTION still destroys canonical records silently.**
+Swap N `## Intake` rows on the board by hand and any register-touching command
+persists the swap — `resolve-intake` included, which declares 0 removals and
+removes 0. The V4 round-5 reviewer measured it at **10 records lost, 10 gained,
+rc 0**, with `perry-lint` going from `16 row(s) drifted` to `0 row(s) drifted`,
+and reproduced it on `asks.jsonl` on the `zh` fixture.
+
+**It is ruled out of scope for this row and I have not touched it.** The
+amendment binds and is explicitly a **count** rule: 32 → 32 is not fewer, and
+closing this needs a per-record identity predicate — which is round 2's door and
+the fifth predicate the amendment forbids. The coordinator is filing it as its
+own row.
+
+It is recorded here because § 3's before/after tables are about a store getting
+SMALLER, and a reader who takes them as "the intake store cannot now be
+corrupted at rc 0" would be wrong. The bound closes the shrink. It does not
+close the swap.

+
+**PASS.**
+
+The bound is real and the fifth door is closed. I reproduced round 4's defect on
+this repository's own data at `afb3a48` and watched the same command refuse at
+the tip with the store byte-identical, on both `resolve-intake` and
+`intake-sweep`. The register still works: the whole intake lifecycle runs green
+on an in-sync copy. `MR` — the round-4 reviewer's own mutation — now reddens a
+**named behavioural test on a drifted board**, which is the specific finding
+round 4 closed on. Every guard I probed dies under its own deletion, including
+the three sub-clauses of the fail-closed `count` check. Spec item 5 is closed:
+`discover` gives the identical six failures on the tip and on a copy of round
+4's tip, so the three `test_risks_store` extras are proven pre-existing.
+
+**I did find a way to destroy canonical records silently — a count-preserving
+substitution (§ 3).** I am ruling it **NON-BLOCKING** and recommending it as its
+own row. It is not a shrink, the binding amendment is a count rule, and closing
+it needs a per-record identity predicate — round 2's door, and exactly the
+"fifth predicate" the amendment forbids. But it is a real, reproducible, silent
+loss and the next round should not discover it by accident.
+
+Everything below was run on **copies** in
+`scratchpad/rjv5-203r5/{tree,tree2,at-afb3a48,state-src,d_*}`. Nothing was
+written inside `scratchpad/review-203r5` and no write-side Perry tool touched
+`/Users/bytedance/proj/Perry`; the live-board runs used `cp -R`'d state. No
+`git checkout`/`stash`/`reset`/`clean` anywhere. Harness and probe files are all
+prefixed `rjv5_`.
+

+
+## 0. The tree is clean and matches its commit
+
+The one place a hand restore could have gone wrong (MB6's timeout):
+
+```
+$ cd scratchpad/review-203r5
+$ git status --porcelain          # empty — no modified, no untracked
+$ git log --oneline -1            ab24b45
+$ md5 -q bin/perry-task           f282d2395f1eae6c5fa077f3e11f958a
+```
+
+Empty status is checked *after* my whole round as well as before. The tip md5
+matches the RESULT's claimed shipped md5, and the `git archive` extraction of
+`afb3a48` matches its claimed `a9af2381b6835ce702629ef5ac23c2b8`. **Verified.**
+
+---
+
+## 1. The structural question — is it the last door or the sixth predicate?
+
+It is one question about two integers, and I could not make it into a predicate
+about anything else.
+
+**No call site can carry the permission without the number.** There are exactly
+three occurrences of `refuse_to_shrink` in `bin/`: the definition
+(`bin/perry-task:2223`) and two calls (`:2423` in `register_change`, `:2698` in
+`commit`). Both pass `event` as a required positional; `declared_removal` is
+computed inside. There is no name-taking overload and no default. I also swept
+every other writer of the three register stores: `bin/perry-tasks` writes them
+only at the six explicit `*-write --from-board` / `*-render --write` sites the
+refusal message itself points to, and `bin/perry-lint` only reads. **Verified.**
+
+**The gate counts the number that gets written.** `register_change` gates on
+`len(derived)` (derived with `current=None`) and then persists
+`records_of(board, ops, current)`. I checked all three derivations
+(`perry_store.intake_records`, `risk_records`, `ask_records`): each returns one
+record per qualifying board row and `current` is only ever used to *merge
+fields*, never to add or drop a record. So `len(records) == len(derived)`
+identically, and the gate is not counting a different list than the one written.
+This is the shape of a sixth door and it is not open.
+
+**`declared_removal` fails closed on all five shapes**, run directly against
+the tip:
+
+```
+unnamed command (add)  -> 0     sweep, count MISSING    -> 0
+empty event {}         -> 0     sweep, count None       -> 0
+no event key           -> 0     sweep, count NEGATIVE   -> 0
+event None             -> 0     sweep, count True/False -> 0   ← the bool case
+event 42 (non-str)     -> 0     sweep, count '99' (str) -> 0
+                                sweep, count 3.0 (float)-> 0
+purge -> 1 · resolve-intake -> 0 · sweep, count 3 -> 3
+```
+
+`isinstance(True, int)` is True in Python and this does not fall for it.
+**Verified.**
+
+**Doors I tried and could not open.** (a) A cross-store allowance: an
+`intake-sweep` event reaches `commit`'s *task*-store call with an allowance of
+`count`, so it nominally holds a licence of N on `tasks.jsonl`. Unreachable —
+`commit`'s non-`purge` branches build `records` from `current` with no removal,
+so the task drop is always 0. Latent asymmetry, not a defect. (b) A legitimate
+removal wrongly blocked on `risks`/`asks`: I read `cmd_risk_clear`, `cmd_answer`
+and `cmd_route` — all three rewrite a cell in place and the row stays, so no
+command shrinks those two stores and the "no declaration" position is correct.
+(c) An inflated sweep count: `cmd_intake_sweep` sets `count: len(discharged)`
+from the board it just mutated, and any hand drift adds to the drop without
+adding to the count, so drift always pushes it over its own bound.
+
+---
+
+## 2. The decisive claim — `MR` reddens a behavioural test. VERIFIED.
+
+Harness `scratchpad/rjv5-203r5/rjv5_mut.py` (uniquely named, refuses a
+non-unique anchor, asserts the old text before replacing, clears every
+`__pycache__`, sleeps past the whole-second boundary on both sides, restores
+from an in-memory copy and md5-verifies). Modules:
+`test_register_store_invariant test_intake_store test_asks_store
+test_risks_store test_purge` — **control 239 tests, OK, 103s**. Every row below
+restored to `f282d2395f1eae6c5fa077f3e11f958a`.
+
+| mutation | red |
+|---|---|
+| **MR** — drop `"resolve-intake"` from `SHRINK_ALLOWANCE` | **3**: `test_resolve_intake_may_not_shrink_a_store_it_removes_nothing_from` (behavioural, drifted board), `test_intake_store.test_a_shrink_permitted_command_on_that_same_board_is_refused` (behavioural, drifted board), and one constant assertion |
+| **MB1** — round 4's exact rule restored (`if after >= before or name in SHRINK_ALLOWANCE:`) | 13 failures / **7 named**, incl. all three bounded behavioural tests **and `test_a_shrink_permitted_command_on_that_same_board_is_refused`** |
+| **MB6** — `"purge": 1` → `0` | 17 failures + 4 errors / **21 named, 15 of them in `test_purge`** driving the CLI end to end |
+| **MB7** — the fail-closed `count` guard → `if False:` | 5 failures / `test_a_declaration_this_tool_cannot_read_declares_nothing` |
+| **MB9** — `register_change` passes `{}` instead of `event` | 6 named, all four sweep/resolve behavioural tests |
+| **M6** — round 3's consecutive-only weakening of the uniqueness clause | **1 — `test_a_repeated_identity_is_no_identity_even_when_no_two_are_adjacent`. Still red.** |
+
+Under round 4, `MR` reddened two assertions *about a constant*. Under round 5 it
+reddens two behavioural tests that drive `perry-task resolve-intake` on a board
+where a shrink is possible. **That is the round-4 → round-5 difference and it
+holds.** (My MB6 count is 15 in `test_purge` where the RESULT says 16; I
+de-duplicate by test name, so a name appearing in two classes collapses. Not
+material.)
+
+### The control — weaker than the RESULT claims, but the tests are not vacuous
+
+The RESULT says *"A clean-board version of any of these tests does not merely
+pass; it fails its own control."* I tested that directly with a probe
+(`rjv5_probe_control.py`, written into the **copy** tree and deleted after):
+
+* **`drifted([1, 2, 3, 4])`** — the helper called with every row kept, i.e. a
+  clean board. **All three controls pass.** `drifted()` asserts (1) the store
+  minted 4, (2) the board holds `len(keep)` rows, (3) the store still holds 4.
+  None of them asserts `len(keep) < 4`, and tidying never touches the store, so
+  control 3 is true regardless. The test then goes red on the **behaviour**
+  assertion (`0 == 0 : ...`), not on the control.
+* **A clean fixture bypassing the helper** (round 4's shape) — also red, also on
+  the behaviour assertion.
+
+So the useful half is true: **the test cannot pass on a clean board either way**,
+and that is what stops round 4's failure repeating. The structural claim is one
+assertion short — `self.assertLess(len(keep), 4, "control: a shrink is
+possible")` inside `drifted()` would make the RESULT's sentence true. I am
+recording this as a **claim-accuracy finding, not a defect**: no shipped code is
+wrong and no test is green for the wrong reason.
+
+### Does any guard survive its own deletion?
+
+I went past the thirteen and killed every guard in the changed surface
+individually. All died:
+
+| guard deleted | red |
+|---|---|
+| `if rule is None: return 0` → `return 99` | 24 failures / **13 named**, all four doors |
+| `isinstance(count, bool)` alone | 1 — `test_a_declaration_this_tool_cannot_read_declares_nothing` |
+| `count < 0` alone | 1 — same test |
+| `not isinstance(count, int)` alone | 1 — same test |
+| `if name in SHRINK_ALLOWANCE:` (message selection) → `if False:` | 4 named |
+| `if shape != "table": return None` → `if False:` | 1 — `test_the_success_line_names_the_register_store_only_when_one_is_written` |
+| `carry_forward_is_addressable`'s per-row identity clause → `if False:` | 1 — `test_a_row_replaced_by_hand_does_not_hand_its_discharge_to_the_newcomer` |
+
+**No guard in this change survives its own deletion.** The three sub-clauses of
+the fail-closed check are each independently covered — including the `bool` one,
+which was the one most likely to be decoration.
+
+---
+
+## 3. The finding: a count-preserving substitution destroys records silently
+
+**NON-BLOCKING. Not a violation of the binding amendment. File it as its own row.**
+
+The invariant is a count rule, so it says nothing about a derivation that
+produces the **same** number of records out of **different** ones. Swap N rows
+on the board by hand and any register-touching command persists the swap,
+destroying N canonical records at rc 0 with `perry-lint` reporting the result as
+clean — **including `resolve-intake`, which declares 0 removals.**
+
+On the live board copied to scratch (32 intake records minted with the gated
+`perry-tasks intake-write --from-board`), 10 real `## Intake` rows deleted by
+hand and 10 filler rows added:
+
+```
+$ python3 bin/perry-lint --root $D          # BEFORE
+  · intake store: 32 record(s), 16 row(s) drifted
+$ python3 bin/perry-task resolve-intake 1 --outcome dropped --reason x --root $D
+perry-task: wrote intake row 1 (resolve-intake) → … + intake.jsonl + …
+rc=0
+$ python3 bin/perry-lint --root $D          # AFTER
+  · intake store: 32 record(s), 0 row(s) drifted
+
+LOST: 10 records    GAINED: 10 records
+```
+
+The single-row form is more realistic and needs no filler at all: hand-delete one
+`## Intake` row, then file one ordinary `perry-task intake`. `before = after =
+32`, drop 0, allowed. One canonical record gone, rc 0, `0 row(s) drifted`. I
+reproduced the same thing on `asks.jsonl` on the `zh` fixture: with `USER-014`
+hand-deleted from `## 用户输入队列`, one `perry-task ask` replaced its record
+with a freshly minted `USER-001` at equal count. (Side note for someone else's
+row: the deleted row's id was **reissued**, which the project's own memory says
+is not cosmetic.)
+
+**Why I am not failing on it.**
+
+1. The amendment binds and it is explicitly a count rule: *"Any derivation that
+   would produce fewer records than the store already holds is a refusal."* 32 →
+   32 is not fewer. Round 4's finding *was* a shrink — the exemption was the
+   loophole. This is not a shrink at all.
+2. Closing it requires comparing record **identity** across the write. That is
+   round 2's door, and the amendment's own words are *"One invariant, not a
+   fourth predicate."* Failing round 5 on this would be ordering the sixth
+   predicate the user declined.
+3. **No tool path reaches it.** All five known doors were tool-produced —
+   `ensure_section`, a section that stopped parsing, a shape change — and every
+   one of those produces a *shrink* and is refused. This needs a human to edit
+   `BOARD.md` and swap rows, which in a board-derived-store design is a request
+   to change the rows.
+4. `perry-lint` reports the drift for the whole window before the write (16
+   rows above). The write launders it; the state is not invisible beforehand.
+
+**What I recommend the row say.** An ordinary write may not silently *replace*
+canonical records either — a derivation whose record set differs from the stored
+set other than at the rows the command addressed should refuse or warn. That is
+a real question and it deserves its own spec, not a fifth patch on this one.
+
+---
+
+## 4. Claims verified with my own measurement
+
+**Board state for every number below:** the branch tip's committed `perry/`
+(i.e. `main` at `6c0d041` plus this row's evidence files) for the test runs, and
+a `cp -R` of `/Users/bytedance/proj/Perry`'s `.perry/` and `perry/` **as of
+2026-08-30** for the reproductions. The live board has grown since the author
+measured — 32 intake rows where the RESULT recorded 30 — so my absolute
+byte/record figures differ from theirs. The signature is identical.
+
+### Claim 1 — both doors closed, side by side. VERIFIED.
+
+Same drifted state built twice: minted at 14328 B / 32 rec / md5
+`ffd24b46805d80b6aa3f762520a2c1be`, then 28 of the 32 `## Intake` rows tidied
+off `BOARD.md` by hand.
+
+| `resolve-intake 1 --outcome dropped` | round 4 (`afb3a48`, md5 `a9af2381…`) | tip (`ab24b45`, md5 `f282d239…`) |
+|---|---|---|
+| rc | **0** | **1** |
+| store after | **1420 B / 4 rec** (md5 `1065b3f4…`) | 14328 B / 32 rec, **md5 unchanged** |
+| `perry-lint` | `0 error(s)` · `intake store: 4 record(s), 0 row(s) drifted` | `0 error(s)` · `intake store: 32 record(s), 28 row(s) drifted` |
+
+**Twenty-eight canonical records destroyed at exit 0 with lint calling it clean,
+versus a refusal and an honest drift count.**
+
+| `intake-sweep` (one row discharged first, 26 tidied off) | round 4 | tip |
+|---|---|---|
+| rc | **0** | **1** |
+| line | `wrote 1 row(s) (intake-sweep)` | `refused — … a drop of 27 — but intake-sweep removes 1 record(s)` |
+| store after | **1770 B / 5 rec** | 14352 B / 32 rec, **md5 unchanged** |
+| `perry-lint` | `intake store: 5 record(s), 0 row(s) drifted` | `intake store: 32 record(s), 26 row(s) drifted` |
+
+It reported sweeping one row and removed twenty-seven.
+
+### Claim 2 — the register still works. VERIFIED, and this is the half I weighted hardest.
+
+On an in-sync live-board copy, tip only:
+
+```
+start                                              32 records
+resolve-intake 1 --outcome dropped     rc=0   →    32 records
+intake-sweep                           rc=0   →    31 records
+intake --title 'an ordinary new request' rc=0 →    32 records
+perry-lint: 0 error(s), 4 warning(s) · intake store: 32 record(s), 0 row(s) drifted
+```
+
+The discharge does not shrink, the sweep shrinks by exactly what it swept, the
+new intake grows. This is **not** TASK-095 round 5's mistake. I also confirmed
+by reading that `risk-clear`, `answer` and `route` all rewrite a cell in place,
+so there is no legitimate removal on `risks`/`asks` for the bound to block.
+
+### Claim 3 — mutations. VERIFIED, six spot-checked (§ 2), including MB6 and M6.
+
+### Claim 4 — the suite gap is closed. VERIFIED.
+
+`test_a_shrink_permitted_command_on_that_same_board_is_refused` shares
+`_hand_delete_the_first_intake_row` with the lint-only test, carries its own
+control (`"control: the store holds four records"`), asserts rc != 0, the
+`removes 0 record(s)` message, and **byte-equality of the store**. It is red
+under MB1 — round 4's exact rule — which is the check that matters. The lint-only
+test now says in its docstring that it is deliberately lint-only and where the
+other question is asked.
+
+### Claim 5 — baselines. VERIFIED, and spec item 5 is genuinely closed.
+
+`bash tests/run` on a copy of the tip, board state as named above:
+
+```
+99 modules · 2929 tests · 360.8s · 8 workers · 2 module(s) red
+  test_diagnose (2)  test_perry_itself_passes_its_own_id_checks
+                     + test_the_queue_register_reconciles_with_the_queue_on_this_repository
+  test_kr_progress_provenance (1)  test_no_current_in_the_payload_claims_to_be_a_measurement
+```
+
+**99 / 2929 / 3, red set identical to round 4's name for name.** None touches a
+register store. Because this is the branch's committed board and not LIVE state,
+the two `test_contract_key_parity` witness tests the spec warns about do not
+appear — as expected.
+
+`python3 -m unittest discover -s tests`, run to completion on **both** trees:
+
+```
+tip copy (cp -R of the git worktree):   Ran 2929 tests …  FAILED (failures=6, skipped=1)
+afb3a48  (git archive extraction):      Ran 2921 tests …  FAILED (failures=6, skipped=4)
+```
+
+**The identical six, name for name**, on both: the three also red under
+`tests/run`, plus `test_risks_store.TestTheReadersAreOneFunction`'s
+`test_the_columns_are_one_list`, `…_register_header_predicate_is_one_object`,
+`…_bullet_and_placeholder_rules_are_one_object`. The failure text is
+`AssertionError: ['ID', 'Risk', 'Opened', 'Status'] is not ['ID', 'Risk',
+'Opened', 'Status']` — two equal lists, two identities, the double-import
+diagnosis confirmed. `test_risks_store` is **green in isolation** (53 tests, OK).
+**The three extras are pre-existing on round 4's tip. Proven, not asserted.**
+First time this claim has been closed on this row.
+
+---
+
+## 5. Rulings on the three declared gaps
+
+**Gap 1 — the `purge` over-declaration is not CLI-reachable. RULING: ACCEPTABLE,
+does not block.** The round-4 reviewer already ruled the identical shape
+acceptable for `test_commit_asks_the_invariant_about_tasks_jsonl`, and the
+argument transfers exactly: the *call* is exercised end to end even though this
+*branch* is not. My own MB6 (`"purge": 1` → `0`) is the proof — 21 named reds,
+15 of them in `test_purge` driving `perry-task purge` through the CLI, which is
+not what a never-reached guard looks like (TASK-095's guard reddened nothing).
+`test_purge_removes_the_one_record_it_names_and_leaves_the_other` runs 2 → 1
+through the CLI, which closes round 4's real hole — a 1 → 0 purge test cannot
+tell "removed exactly one" from "removed everything". The test's docstring
+states what it does and does not claim. Keep both.
+
+**Gap 2 — the unreconciled `discover` discrepancy. RULING: ACCEPTABLE; nothing
+is hidden, but the stated explanation is wrong and should be corrected.** I ran
+`discover` myself on **both** tree layouts — a `cp -R` of the git worktree
+(the round-4 reviewer's shape) and a `git archive` extraction (the author's) —
+and got the author's figures on **both**, with no `ModuleNotFoundError: No
+module named 'tests'` and no `test_host_support` flake in either. So the
+author's numbers reproduce and are stable across layouts; the round-4 reviewer's
+two errors were environmental (a stray `tests` package on `sys.path` — which is
+literally row 1 of this repository's own `## Intake`) and the third is a
+recorded flake. The author's attribution to "tree layout" is **not supported by
+my measurement** and should be struck from the record rather than repeated. It
+hides nothing: the failure count is the identical six on both trees and neither
+error moves with the bound.
+
+**Gap 3 — the five things not re-tested. RULING: ACCEPTABLE, and I closed one of
+them.** I drove a **`zh` board through a bounded refusal** myself
+(`tests/fixtures/sample-project-zh`, asks store at 2 records, both
+`## 用户输入队列` rows hand-deleted, `perry-task ask`):
+
+```
+perry-task: refused — `ask` would take …/asks.jsonl from 2 record(s) to 1, and an
+ordinary write may never make a canonical store smaller (USER-906). …
+rc=1 ; store unchanged at 2 records
+```
+
+The localized heading resolves and the refusal fires. On the rest: crash recovery
+at the rename boundaries is a fair skip because the refusal is raised in
+`register_change` *before* the plan is built and before anything is staged — I
+confirmed the ordering by reading `commit`, so the bound cannot reach
+`replace_canonical_pair` at all. Concurrency between two writers and the
+full suite per mutation are standard omissions at this scale. Not re-measuring
+`main` at `6c0d041` is fine: I measured the tip at 99 / 2929 / 3 and the red set
+is name-for-name round 4's, which is what the delta claim needs.
+
+---
+
+## 6. What I did NOT check
+
+1. **Crash recovery at the rename boundaries** — reasoned, not re-run. No
+   `os._exit(9)` probe this round.
+2. **Concurrency between two Perry writers.** Not exercised.
+3. **The full suite per mutation.** Five modules / 239 tests each, as the author
+   did.
+4. **`main` at `6c0d041` was not re-measured** by me either.
+5. **The remaining seven of the thirteen mutations** (MB2, MB3, MB4, MB5, MB10,
+   M1, MB1b) were not re-run; I spot-checked six and swept seven guards the
+   author did not mutate.
+6. **`risks.jsonl` under a bounded refusal** was not driven end to end — I
+   verified by reading that no command shrinks it and drove the `asks` case
+   instead.
+7. **The `test_contract_key_parity` and `test_board_render` data-dependent
+   failures** — my board state does not produce them, so I could not
+   independently confirm they are the defects the spec says they are.
+
+---
+
+## 7. Disclosure
+
+Invoking `review-203r5/bin/perry-*` was avoided entirely — every run used the
+copies — so no `__pycache__` was written into the reviewed worktree. `git status
+--porcelain` there is empty at the end of this round, and `bin/perry-task` is
+still `f282d2395f1eae6c5fa077f3e11f958a`. The mutation harness
+(`rjv5_mut.py`), the clean-board probe (`rjv5_probe_control.py`, deleted after
+use from the copy tree) and every scratch directory are uniquely prefixed
+`rjv5`.

+---
+
+## Amendment 2026-08-29 — USER-906, option B. This section binds.
+
+Three rounds failed V4, all three ending in the same defect: an ordinary command
+silently truncates a canonical register store. The user answered USER-906 with
+**option B**. Where this amendment and the original disagree, this wins.
+
+### The invariant
+
+**An ordinary write may never SHRINK a canonical store.** Only an explicit
+removal command — `purge`, `resolve-intake`, `intake-sweep` — may reduce a
+record count. Any derivation that would produce fewer records than the store
+already holds is a **refusal**, not a write.
+
+One invariant, not a fourth predicate. It has to cover every door found across
+three rounds without asking a new question at each: the command name (round 1),
+the non-unique identity tuple (round 2), the four section shapes, and the
+`ensure_section` ordering (round 3).
+
+**Explicitly rejected: option A**, evaluating the gate against the board as it
+was at command entry. That is the fourth "move the question" fix on this row and
+the first three all looked principled too. A round 4 that snapshots the gate does
+not satisfy this spec.
+
+### Scope change
+
+`asks.jsonl` is **IN scope**. The original's "out of scope" line is superseded:
+DoD Must-Have 2 of phase 003 names `intake.jsonl` and `asks.jsonl` explicitly,
+and the user declined options C and D, which were the two ways to drop it. All
+three registers — risks, intake, asks — are this row's.
+
+### The regression test comes first, and must be RED before the fix
+
+Reproduced on this repository's own data (`evidence/2026-08/TASK-203-merge-hold.md`):
+with the board's `## Intake` section absent, `perry-task add --track intake`
+takes `perry/intake.jsonl` from 8240 bytes / 24 records to **0**, exit code 0,
+and `perry-lint` then reports `0 error(s)` and `intake store: 0 record(s), 0
+row(s) drifted`.
+
+Write that test, watch it go red, then fix. A fix whose regression test was
+written after it is not accepted here — three rounds of this row shipped tests
+that were green for the wrong reason.
+
+### Also required in this round, each found by the round 3 reviewer
+
+1. The third shape test is **vacuous**: the legend table lands under `## Top
+   risks` because `ensure_section` anchors `## Intake` before `## P0`, so the
+   `foreign` shape has **no test on any register**. Give the foreign shape a
+   real test on each of the three registers.
+2. The uniqueness test **cannot distinguish uniqueness from adjacency** — it
+   follows with an `intake`, which trips the ordinary positional check first, so
+   it passed with the uniqueness guard deleted. Prove uniqueness alone.
+3. `load_register_records` lets `JSONDecodeError` escape as a bare traceback
+   where every other failure in that file is a `Refused`.
+4. `readable_as_register`'s `section` parameter is dead — in the commit that
+   answered a finding about a dead parameter.
+
+### Where round 4 starts
+
+**From `main`, not from `coding/task-203-register-stores`.** That branch is held
+out of `main` because the truncation is reachable on this repository; the
+measurement is `evidence/2026-08/TASK-203-merge-hold.md`. Read the branch for
+what it learned — `REGISTER_EVENTS` is complete both ways over 21 subcommands,
+the crash-recovery work at all three rename boundaries holds, the 60-cell
+shape matrix is real — and rebuild on the invariant.
+
+### Verification — V4, amended
+
+Items 1 through 5 of the original still hold, plus:
+
+6. The invariant holds on every one of the four doors, each with its own named
+   test: command name, non-unique identity, the four section shapes on all
+   three registers, and `ensure_section` ordering on a queue-mode track.
+7. An explicit removal command is shown to still work — `resolve-intake` and
+   `intake-sweep` reduce the count, and their tests prove the invariant does not
+   block them.
+8. Every mutation is exact: anchor by line, assert on the old text before
+   replacing, clear `__pycache__`, wait past the whole-second boundary.
+9. Baselines name **both** the runner and the tree. `bash tests/run` and
+   `python3 -m unittest discover -s tests` disagree by 3 on this repository, and
+   `test_diagnose`'s queue-register test reconciles against the live board.
+   `main` at 70eae67 is 98 modules / 2882 tests / 3 failures under `tests/run`.

+# TASK-209 — result: the store-drift census covers six stores, not two
+
+> Serves **P003-O1-KR2** (`perry/phase/003-storage-code.md`): *stores for which
+> one run of `perry-lint --root .` prints a drift verdict*. Target **6 of 6**,
+> baseline **2 of 6** (tasks, risks).
+>
+> Verified 2026-08-29 by the PMO, against code that had already landed. Rung **V3**.
+
+## Why this file is written a day after the code landed
+
+The row was dispatched on 2026-08-28 and its `Next action` still read
+`dispatched to claude-subagent; awaiting RESULT` when this session opened. The
+dispatch limiter reported **no active dispatches**, and the work was already on
+`main`. The agent's run stalled on a watchdog before it could report back, and
+the commit was made on the user's explicit instruction — recorded in the commit
+message of `e993d85`.
+
+So the row sat `in_progress` while its deliverable was merged and green. That is
+the third instance in two days of the limiter's bookkeeping disagreeing with
+what actually ran (`journal/2026-08/2026-08-28.md` records the other two: an ESC
+that killed two agents, and a reserved slot whose dispatch call was never made).
+**The verification below was therefore run fresh rather than taken from the
+commit message**, because a self-report from a run that did not finish is not
+evidence.
+
+## What landed
+
+| Commit | Subject |
+|---|---|
+| `e993d85` | TASK-209: the store-drift census covers six stores, not two |
+| `b7cef79` | TASK-209 fix: the entry point goes last, so the appended tests run standalone |
+| `5cac6b5` | Merge `coding/task-209-store-drift-census` |
+
+`bin/perry-lint` +220 lines, `tests/test_store_drift.py` +289 lines.
+
+## Verification, re-run 2026-08-29
+
+**1 · The census prints a verdict line for all six declared stores.**
+`python3 bin/perry-lint --root .`:
+```
+  · store: 225 record(s), 0 row(s) drifted
+  · risks store: 4 record(s), 0 risk(s) drifted
+  · no `intake.jsonl` — drift against the intake store is unchecked, not clean
+  · no `asks.jsonl` — drift against the ask store is unchecked, not clean
+  · OKR store: 36 record(s), 0 row(s) drifted
+  · config store: 9 record(s), 0 row(s) drifted
+```
+Six lines for the six projection stores declared in `schema/state-schema.json §
+claims[]` — `tasks.jsonl`, `okr.jsonl`, `risks.jsonl`, `intake.jsonl`,
+`asks.jsonl`, `.perry/config.jsonl`. Baseline was two: `okr.jsonl` and
+`.perry/config.jsonl` printed nothing at all while `perry-okr diff` and
+`perry-config diff` both worked and the census called neither.
+
+**2 · The test suite is green.** `python3 tests/test_store_drift.py`:
+```
+...............................................
+Ran 47 tests in 37.632s
+
+OK
+```
+
+**3 · The gate has been shown able to go red** — the phase's operating rule, and
+phase 002's lesson 4. `e993d85`'s message records two mutations and one removal
+run on a scratch copy of the state root before the green was believed: editing
+`KR-O1.1`'s metric cell moves the OKR line to `1 row(s) drifted` and warnings 4
+→ 5; editing the intake track's WIP cell moves the config line to `1 row(s)
+drifted`; deleting `okr.jsonl` produces `unchecked, not clean`.
+
+That third check is re-run independently and at six-store scale in
+**`evidence/2026-08/TASK-229-result.md`**, which removes every one of the six in
+turn. All six report `unchecked`. The two claims are therefore not resting on
+the same unfinished run.
+
+## Verdict
+
+**6 of 6.** `P003-O1-KR2` is at target. ADR-007's guarantee — a store is
+canonical and its markdown is a projection — is now checkable for every store
+Perry declares, rather than for one of six.
+
+## What this does not close
+
+`P003-O1-KR2` also carries **TASK-067** (*the writer can destroy the table it
+writes to, and `perry-lint` cannot see it*), which is `blocked` and untouched by
+this row. A census that reports drift is not the same as a writer that cannot
+ragged-row its own table.

+# TASK-211 — result: the dispatch limiter says what it cannot know
+
+> Branch `coding/2026-08-29-overnight-batch`, commit `835555d`. Rung **V3**.
+> Measured 2026-08-29.
+
+The row folded two intake findings into one, correctly: they are one tool
+failing to tell its caller what it does not know.
+
+## Half one — already fixed, and pinned rather than deleted
+
+Filed as *"an unknown subcommand exits 0, so a typo silently disables the
+concurrency cap"*. The row's own Verification names the check: *calling
+`acquire`, which is not a subcommand, fails loudly.*
+
+Re-measured before writing anything:
+
+```
+$ bash bin/perry-dispatch-limit acquire ; echo "exit=$?"
+Unknown command: acquire
+perry-dispatch-limit — track concurrent /perry work dispatch slots.
+exit=2
+```
+
+**Already true.** The `*)` branch exits 2 and prints the usage. The row's
+premise was stale. It is pinned by a test rather than struck out: an exit code
+nobody asserts is one a later refactor can drop silently, and this row exists
+because that exact thing happened once.
+
+## Half two — live, and the expensive one
+
+`list` reports marker **files** and reads as though it reports running agents.
+
+It cannot observe. `registered_pid` is the field that looks like it would let
+it, and it does not — it is the pid of `perry-dispatch-limit` **itself** at
+`register` time, and that process exits within milliseconds. Measured:
+
+```
+$ bash bin/perry-dispatch-limit register TASK-999 claude-subagent
+🟢 Slot reserved: TASK-999 (claude-subagent). Now 1 / 2 …
+$ kill -0 49907          # the registered_pid from the marker
+DEAD — the pid is the registrar's, and it exited when register returned
+```
+
+`kill -0` reports dead for **every marker ever written**, including one whose
+agent is alive and working. So both failure directions are real and neither is
+detectable at this layer:
+
+| direction | what happens | seen |
+|---|---|---|
+| agent dies, marker stays | the slot is held until the stale sweep | 2026-08-28, an ESC killed two agents |
+| marker reaped, agent lives | the cap is short by one, silently | 2026-08-21, TASK-160 |
+| marker written, dispatch never made | a phantom in-flight row | 2026-08-28, 20 minutes |
+| agent finished, row never closed | `list` says 0 while a row says "awaiting RESULT" | **2026-08-29, TASK-095 and TASK-209** |
+
+Three instances in two days, every one caught by a human reading two numbers
+side by side rather than by any check.
+
+## What shipped
+
+The deliverable offered two branches: *"list reports observation, **or** says
+plainly that it reports bookkeeping and observes no process."* Observation is
+not available here — the pid is not a handle and the tool never learns the
+agent's — so the second branch is what ships, and it is stated every time
+rather than only when something looks wrong. The caller cannot tell those
+cases apart either; that is the defect.
+
+`(no active dispatches)` gets the note too, and is the dangerous line: it reads
+as *"nothing is running"* and means *"no marker file exists."* That is the
+sentence misread on 2026-08-29.
+
+**The note is on stderr**, per this file's own rule at `clean_stale`: *"`check`
+and `list` have parseable stdout and a warning is not part of their answer."*
+`TestStdoutStaysParseable` asserts stdout stayed exactly the listing — two
+lines, no prose.
+
+The marker itself now carries `_registered_pid_note`, so a reader who finds one
+on disk without this evidence file beside it learns the same thing.
+
+## Verification
+
+**Shown able to go red**, three mutations, each restored byte-identical
+(`md5` checked):
+
+| mutation | result |
+|---|---|
+| drop the empty-listing note | 1 failure |
+| move the note to stdout | 2 failures |
+| unknown subcommand exits 0 again | 1 failure |
+
+`tests/test_dispatch_limit_honesty.py` — 10 tests, each with its own `HOME`, so
+the real `~/.cache/perry` is never touched.
+
+**Suite**: 3 modules red before and after (`test_contract_key_parity` 2,
+`test_diagnose` 2, `test_kr_progress_provenance` 1) — all pre-existing on
+`main`. This change adds none.
+
+## What this does NOT fix
+
+**Nothing compares a board row claiming `dispatched` against this tool
+reporting 0 in flight.** That is the check which would actually have caught all
+three incidents, and it is a cross-check between two payloads — `perry-state`'s
+board rows and the limiter's markers — not a property of a bash script that
+knows nothing about the board. Filed to `## Intake` on 2026-08-29, where it
+belongs as its own row.

+
+> Branch `coding/2026-08-29-overnight-batch`. Rung **V3**. Measured 2026-08-29.
+
+## The defect
+
+`bin/perry-task` carried
+
+```python
+ABSENT = {"", "—", "-", "–", "n/a", "na", "tbd", "无", "none"}
+```
+
+and three readers matched against it with `.lower() in ABSENT`:
+`evidence_paths`, `evidence_relations`, and `parse_depends`.
+`lib.is_blank_cell` is the one rule — it reads the declared spellings out of
+`schema/state-schema.json § i18n.blank_cell` — and this set was the **fourth
+copy** of it.
+
+## What the copy missed, measured
+
+| value | old `ABSENT` | `is_blank_cell` |
+|---|---|---|
+| `待定` | False | **True** |
+| `不适用` | False | **True** |
+| `暂无` | False | **True** |
+| `**—**` | False | **True** |
+| `` `n/a` `` | False | **True** |
+| `" — "` | False | **True** |
+| `—` `n/a` `na` `tbd` `无` `none` | True | True |
+| `TASK-050` | False | False |
+
+So on a Chinese board `Depends on: 待定` parsed as a **real dependency id**, and
+`depends_on_resolved` reported a task waiting on a row that does not exist and
+never will.
+
+## Why the swap is safe — measured, not cited
+
+TASK-163 established `is_blank_cell` is a strict **superset**. This row
+re-measures it rather than citing it: **every value the old set called absent,
+the one rule also calls absent.** Nothing any caller treated as empty became
+present. `TestTheSupersetHolds` is that measurement, and it is the assertion
+that would have to fail before any of the behaviour change could be a
+regression. It carries a control — a rule that called everything blank would
+pass the superset test and be useless.
+
+## After
+
+```
+parse_depends('待定')             -> []
+parse_depends('**—**')           -> []
+parse_depends('TASK-050')        -> ['TASK-050']
+parse_depends('TASK-050, 待定')   -> ['TASK-050']      # the mixed cell
+parse_depends('TASK-050、TASK-051') -> ['TASK-050', 'TASK-051']
+```
+
+`evidence_paths` and `evidence_relations` read every placeholder as no
+evidence, and a real path still reads.
+
+## Two things this row got wrong first, and both are recorded because they were
+
+**The first draft's mutation was green.** Reverting the three head-rule call
+sites passed all ten tests: `parse_depends` reaches the same answer through its
+token loop, so its head rule is redundant for these inputs, and
+`evidence_paths` / `evidence_relations` were **never exercised at all**. A row
+whose deliverable names four call sites needs a test that reaches four.
+`TestTheEvidenceReadersToo` was written after that green, and reverting the
+head rules now costs 5 failures.
+
+**Retiring the name broke two importers, and the full suite caught it.**
+`tests/test_evidence_relation.py:54` read `ABSENT = PT.ABSENT` under the comment
+*"Read off the tool so this module cannot disagree with it"* — the right
+instinct, pointed at the wrong rule — and `tests/test_task_writer.py:2192` did
+the same inline. Both now go through `lib.is_blank_cell`, so they agree with the
+tool **and** with a Chinese board. I should have swept for importers before
+renaming; the category discipline this repository applies to source applies to
+a constant's readers too.
+
+`tests/test_conformance.py`'s `C.ABSENT` is a different module's constant
+(`bin/perry-conform`) and is untouched.
+
+## Mutation
+
+| mutation | result |
+|---|---|
+| put a local set back in `parse_depends` | 1 failure |
+| revert the three head-rule call sites | 5 failures |
+

+## The defect
+
+`BOARD.md`'s preamble read:
+
+```
+> Last updated: 2026-08-16 (21st pass — DESIGN-004 handed off, 6 tasks)
+```
+
+on **2026-08-29** — thirteen days stale, on a file `perry-task` re-renders
+dozens of times a day. `perry-state` publishes it as `board.last_updated` and
+the standup prints it, so a number every reader takes at face value was
+maintained by nobody.
+
+## The decision: the writer, not the renderer
+
+The spec offered two branches — *"the header is written by the renderer, or
+removed"*. Neither literal branch is right, and the reason is worth recording.
+
+**Not the renderer.** `perry-tasks render --byte-compare` and `perry-lint`'s
+store-drift census both compare a fresh render against the file on disk. A
+renderer that stamped today's date would report the board as **drifted every
+morning** until somebody happened to write to it. A check that goes red on the
+passage of time is a check people learn to ignore, and this repository has
+already paid for one of those.
+
+**Not removal either.** `board.last_updated` is a published payload key;
+removing it is a contract change requiring a version bump, and the field is
+useful once it is true.
+
+So: *"last updated" means the last **write***, and a re-render is not a write.
+`commit()` stamps it before rendering, which also means the rendered text
+carries the new header — so the next render reproduces the file byte-for-byte
+and the drift check stays quiet.
+
+## Verification
+
+Measured on a full copy of Perry's own state (board, store, event log):
+
+| | before | after one `perry-task next` |
+|---|---|---|
+| header | `2026-08-16 (21st pass — …)` | `2026-08-29` |
+| `perry-lint` store drift | `225 record(s), 0 row(s) drifted` | `225 record(s), 0 row(s) drifted` |
+| `render --byte-compare` | — | **clean** |
+| `render --write` afterwards | — | header **unchanged** |
+
+`perry-state --json` → `board.last_updated: 2026-08-29`, agreeing with the file.
+
+## Two ways not to cry wolf, both tested
+
+**A board with no such header does not get one.** The line is Perry's own
+template convention, not a required section; adding it to somebody else's board
+would be this tool writing a line the project never asked for.
+
+**The matcher anchors on the quote line.** `TASK-215`'s own title contains the
+words *"Last updated header"* and sits in a table row on the board this ships
+with — line 94 of the fixture I measured on. A looser matcher would have
+rewritten a task's title on the first write. The matcher also takes the
+localized spelling and the full-width colon, so a Chinese board is not silently
+skipped.
+
+## What was dropped, deliberately
+
+The editorial parenthetical. A rendered file's header is not a place for prose
+nobody re-derives; `journal/2026-08/2026-08-16.md` is where *"21st pass,
+6 tasks"* belongs and already carries it.
+
+## Mutation
+
+| mutation | result |
+|---|---|
+| don't stamp at all | 4 failures |
+| drop the quote anchor | 1 failure — the task-row case |
+| invent the header when absent | 1 failure |
+
+Each restored byte-identical (`md5` checked). The third mutation's first
+attempt did not match its anchor and reported a meaningless OK; it was re-run
+with a unique anchor, which is the only reason it counts.
+
+**Suite, both runners**: `bash tests/run` 3 modules red / 5 failures;
+`unittest discover` 2849 tests / 8 failures — identical sets to `45a355d`. This
+change adds none.

+# TASK-216 — result: the foreign-write guard reads the summary tables too
+
+> Branch `coding/task-216-ownership-guard`. Rung **V3**. Measured 2026-08-29.
+
+## The defect, in two halves
+
+`tests/test_ownership.py`'s foreign-write scan is the mechanical half of the
+signed hand-off contract — the one rule `perry-lint` cannot check and
+`SKILL.md § The hand-off contract` says shows up later as silent cross-lane
+writes. It had two blind spots that compound:
+
+1. **It scanned `<lane>/reference/*.md` only.** Procedures live there, which is
+   why the original scan looked there — but a lane's `SKILL.md` carries the
+   summary **table**, and a summary table is exactly where a stale ownership
+   claim survives longest: read on every invocation, edited least.
+2. **`WRITE_VERBS` matched `write` and not `writes`.** A summary table is
+   written in the third person, so *"`work` writes `DECISIONS.md`"* walked
+   straight past a guard built to catch that sentence.
+
+Either alone would have hidden the defect. Together they made the guard blind
+to its own subject.
+
+## Measured before changing anything
+
+| scan | offenders |
+|---|---|
+| shipped verbs, `reference/` only | **0** |
+| widened verbs, `reference/` only | **1** — one false positive |
+| widened verbs, `reference/` **+ `SKILL.md`** | **2** — both false positives |
+
+**A correction to this row's own record.** The deliverable predicts **3** at the
+widest, *"`goals/SKILL.md:126` (the true positive, fixed 2026-08-28) plus
+`decide/SKILL.md:26`"*. It is 2, because that true positive was already
+corrected in `2e41336` before this row was worked. The row's number described
+the tree as it stood when the row was written. The true positive is therefore
+reached by **mutation** rather than by the scan, which is what the row's own
+Verification asks for.
+
+## The two carve-outs, both measured false positives
+
+- **`no longer`** — `work/reference/subcommands.md:424` reads *"**`work` no
+  longer writes `DECISIONS.md` or `decisions/` at all.**"* That is the refusal
+  the contract asks for. The existing `\bnot\b` does not cover it.
+- **`hands off`** — `decide/SKILL.md:26` reads *"`design` hands off to `pmo`"*.
+  That is the hand-off, not the write. The shipped carve-out had
+  `hand (it |the |off)`, so it matched `hand off` and not `hands off` — **the
+  same third-person blind spot as the verb list, one clause over.**
+
+## Verification — the row's own four, all run
+
+| mutation | result |
+|---|---|
+| revert the `goals/SKILL.md:126` correction | **RED** — `goals/SKILL.md:126 → writes evidence/<YYYY-MM>/retro.md` |
+| drop the `no longer` carve-out | **RED** — the false positive returns |
+| drop the `hands off` tolerance | **RED** — the false positive returns |
+| **narrow verbs + the real defect restored** | **GREEN** |
+
+The last is the decisive one. With the shipped verb list and the actual defect
+put back, the guard reports nothing — which is the state this repository was in
+while `goals/SKILL.md` claimed `evidence/retro.md` for the wrong lane and the
+correction sat two files away in `goals/reference/phases.md:229`.
+
+Each mutation restored from a byte copy and the suite re-checked green.
+
+## What changed
+
+- `lane_pages()` returns `<lane>/reference/*.md` **plus** `<lane>/SKILL.md`.
+- `WRITE_VERBS` takes the `s` on every verb.
+- `CARVE_OUT` is a named constant rather than an inline regex, with the two new

+## The answer
+
+`.perry/conformance.md` gained the row
+
+```
+| knowledge/goals/linkage-graph-before-first-add.md | 2 | 2026-08-28 | declare |
+```
+
+because **the user ran `perry-conform declare` in their own terminal**, 52 seconds
+after the first of the two readings. Writer #1, the documented one, invoked by
+hand outside the agent's transcript.
+
+`~/.zsh_history` line 3763, with `EXTENDED_HISTORY` timestamps:
+
+```
+: 1787912711:0;python3 /Users/bytedance/.claude/skills/perry/bin/perry-conform declare knowledge/goals/linkage-graph-before-first-add.md --root .
+```
+
+`1787912711` = **2026-08-28T10:25:11Z** (18:25:11 +0800).
+
+The record is the *only* documented writer, run with exactly the argument the
+tool's own status line had printed to the screen 52 seconds earlier:
+
+```
+   · knowledge/goals/linkage-graph-before-first-add.md undeclared
+   23/24 declared and matching. Declare one with `perry-conform declare <file> --root .`.
+```
+
+**ADR-004's contract was never violated.** `bin/perry-conform:11` and `:41` are
+still true of that file. Two things failed, and the first is the one that
+matters.
+
+**The record cannot answer the question it exists to answer.** That is the
+mechanical root cause, and it is why this took three transcripts and a shell
+history instead of one command:
+
+- the four columns are `File | Shape version | Declared | Route`. `Declared` is
+  a **date**. All eight rows added that day read `2026-08-28`, so the file
+  cannot order them, cannot separate 10:25:11 from 09:19:35, and cannot say
+  that three separate invocations were involved rather than one.
+- there is no actor column. `Route` separates `declare` from `migrate`; it does
+  not separate *the agent ran declare* from *the user ran declare*, which is the
+  exact distinction this investigation turned on.
+- **`perry-conform` never writes to `.perry/events.jsonl`** — 0 references,
+  against 9 in `bin/perry-task`. Perry's one append-only record of *what
+  happened* omits every write to the file that gates every write.
+
+Given those three, no amount of care inside the session could have answered
+this. The second failure is the inference that filled the gap: the session read
+"no `perry-conform declare` was run" off its own transcript, and **its own
+transcript is not the machine**.
+
+### The procedure that lesson is worth
+
+"A transcript is not the machine" is prose until it names what to consult. Before
+a session asserts that *nobody did X*, as opposed to *I did not do X*, it must
+check the machine-side records — none of which are Perry, and all of which were
+decisive here:
+
+1. **`~/.zsh_history`** (with `EXTENDED_HISTORY`, `: <epoch>:<elapsed>;<cmd>`) —
+   the user's own hands. This is the record that answered TASK-226, and it is
+   the *first* place to look whenever the tool prints a command for the user to
+   run. Grep for the tool name; convert the epoch; compare against the window.
+2. **Every transcript on the host, not just this session's** —
+   `~/.claude/projects/*/*.jsonl` **plus** `*/subagents/*.jsonl`. Filter by
+   timestamp window and read each entry's `cwd`. A sibling session in another
+   project can still write this tree.
+3. **The harness's background-task directory** — a command moved to the
+   background keeps running across the window. Its start is a
+   *"moved to the background (ID: …)"* tool result; its end is the moment its
+   `.output` file gains bytes. Both are timestamps you can compare.
+4. **`~/.claude/settings.json` hooks** — `Stop`, `SessionEnd`, `PostToolUse` and
+   friends run commands the transcript never shows.
+5. **`git log`/`git diff` on the file, and the file's own mtime** — and note
+   what they *cannot* tell you: `render()` rebuilds the whole file on every
+   write, so a diff against `HEAD` shows every row added since the last commit
+   with no way to order them.
+
+Steps 1–4 are all outside Perry. That is the finding, not an aside.
+
+### The timeline, to the second
+
+All times UTC. Agent rows are from
+`~/.claude/projects/-Users-bytedance-proj-Perry/5bf5be56-…jsonl`; the shell row
+is from `~/.zsh_history`.
+
+| time | actor | what |
+|---|---|---|
+| 10:22:47 | agent (bg) | the full suite finishes — `tail -20` flushes 622 bytes |
+| **10:24:19** | agent | **reading 1** — `perry-lint` says *23 declared*; `perry-conform status` says `23/24`, knowledge card `undeclared` |
+| **10:25:11** | **the user, in their own shell** | **`perry-conform declare knowledge/goals/linkage-graph-before-first-add.md --root .`** |
+| 10:25:13 | the user | submits `/perry decide rfc close-phase` to the agent — 2 s later |
+| 10:27:26 | agent | `AskUserQuestion` on the DESIGN-012 title |
+| 10:30:08 | agent | heredoc creates `perry/design/DESIGN-012-close-phase.md` — this is the denominator's +1 |
+| 10:30:33 | agent | `perry-lint` says *24 declared* |
+| **10:30:42** | agent | **reading 2** — `24/25`, `design/DESIGN-012-close-phase.md` is now the undeclared one |
+
+The two-second gap between the shell command and the next prompt is why the
+session never saw it: the user declared the file, then immediately typed the
+next instruction.
+
+### It was not the first time — the same cause twice more that day
+
+The eight rows commit `2e41336` carries all date `2026-08-28`. All eight came
+from the same hand, and each was preceded by the agent printing the exact
+command it is forbidden to run itself — `SKILL.md:197`: *"never run
+`perry-conform declare` for the user; adoption proposes, the user declares"*:
+
+| shell epoch | UTC | command | what appeared |
+|---|---|---|---|
+| 1787908775 | 09:19:35 | `bin/perry-conform declare phase/003-storage-code.md --root . && … phase/003-linkage.md --root .` | the 2 rows session `163a7a05` found at 09:21:20 |
+| 1787910107 | 09:41:47 | `bin/perry-conform declare design/DESIGN-008… DESIGN-009… DESIGN-010… DESIGN-011… phase/002-linkage.md --root .` | the 5 rows undeclared at 09:24:56 and conformant by 10:24:19 |
+| 1787912711 | 10:25:11 | `… declare knowledge/goals/linkage-graph-before-first-add.md --root .` | **the row this task is about** |
+
+Each is verbatim the command an assistant had put on screen minutes earlier
+(`163a7a05` at 09:03:49 and again at 09:33:17 / 09:35:24). The first episode was
+already noticed and investigated *inside the session*, at 09:20–09:23, and
+closed as unexplained for the same reason: the session searched its own
+transcript, found no `declare`, and concluded a third writer.
+
+## Reproduction — exact, byte for byte
+
+Sandbox: `git archive HEAD` of this branch into a scratch directory (**never**
+`/Users/bytedance/proj/Perry`). `DESIGN-012` and `DESIGN-013` held out to
+recreate the 2026-08-28 file set.
+
+> **Replay this against the skill at `0179c02^`, not against `main`.** These
+> totals were measured on this branch, forked at `ee0b36a`. `0179c02` —
+> TASK-235, *"DECISIONS.md stops existing"* — removed that file's schema spec
+> and merged at 2026-08-30 00:42, **after** this run. On `main` the same recipe
+> yields `22/23` and `23/24`: every count below is one lower, because the
+> denominator lost a file. Checked out at `0179c02^` the numbers reproduce
+> exactly. The totals here were measured, not carried forward — the recipe just
+> stopped replaying, and that is worth a sentence rather than a silent
+> discrepancy for the next reader.
+
+```
+### READING 1 (T1 analogue)

+### READING 2 (T2 analogue)
+   · design/DESIGN-012-close-phase.md             undeclared
+   24/25 declared and matching.
+```
+
+Both cards and both totals match the observation exactly, including which file
+is named as undeclared in each reading.
+
+Stronger still — with only the `Declared` cell normalised from today's date back
+to `2026-08-28`, the reproduced file is **byte-identical** to the one the real
+tree carried at reading 2:
+
+```
+reproduced (date normalised to 2026-08-28): ff66fbf343266a0f339fc48df8b0cd44
+committed at 2e41336 / ee0b36a           : ff66fbf343266a0f339fc48df8b0cd44
+```
+
+One `perry-conform declare` with that one argument produces that exact file
+from the reading-1 file.
+
+**Not "no other input produces it"** — an earlier draft of this document said
+that and it is false. A decorated row already present in the file produces the
+same canonical bytes on the next write; see § *The decoration-laundering class*
+below. What is established is the direction that matters here: the observed
+command is sufficient, and the reading-1 file carried no decorated row (0
+unreadable, `render` a fixed point), so nothing else was available to produce
+it.
+
+## Every path eliminated, and how
+
+Each row is an experiment, not a grep. Commands 1–13 were run against the
+sandbox with `md5 .perry/conformance.md` taken before and after each.
+
+| # | path | how it was eliminated | result |
+|---|---|---|---|
+| 1 | `perry-lint --root .` | ran it; md5 before/after | UNCHANGED |
+| 2 | `perry-conform status` | ran it | UNCHANGED |
+| 3 | `perry-conform check <file>` | ran it | UNCHANGED |
+| 4 | `perry-conform declare --dry-run` | ran it | UNCHANGED |
+| 5 | `perry-state --json` | ran it | UNCHANGED |
+| 6 | `perry-state --section recovery` / `interrupted` / `design` / `attribution` | ran all four — `recovery` was the live suspect, since a half-applied `perry-migrate` restore point would finish through `C.declare` | UNCHANGED; `pending_transactions: []` |
+| 7 | `bash bin/perry-update-check` and `--force` | ran both. **Not considered by the spec** and it is the one *bash* thing in the window; it is a `git fetch`/ff-only-pull probe that in dev mode (symlink install, dirty tree) only fetches | UNCHANGED |
+| 8 | `perry-goals link --project` | ran it. It imports `perry-conform` and calls `gate()`; `gate()` is read-only and `--migrate` is exempt from it, not from the record | UNCHANGED (refused by the gate, wrote nothing) |
+| 9 | `perry-goals list`, `perry-explain`, `perry-task list`, `perry-tasks`, `perry-knowledge`, `perry-diagnose` | ran all six | UNCHANGED |
+| 10 | the heredoc that created `DESIGN-012` | created a new file under `perry/design/` | UNCHANGED — creating a state file never declares it |
+| 11a | `bin/perry-migrate` (writer #2) | it is the *one* thing the record can rule out on its own: `bin/perry-migrate:1877` calls `C.declare(…, route="migrate")` unconditionally, and the row's `Route` cell reads `declare` | eliminated by the record itself |
+| 11 | a third writer in the tree | **This row is a grep, not an experiment — the only one in this table, and it is named as such.** `declare()` has exactly two call sites: `bin/perry-conform:594` (the CLI) and `bin/perry-migrate:1877`. `render()` has exactly one caller, `bin/perry-conform:474`. `P.Declaration(` is constructed in exactly two places, `bin/perry-conform:469` and `viewer/parsers.py:433`. Three other files name `CONFORMANCE_FILE` and none of them writes it: `viewer/parsers.py:368,399` defines and reads it; `bin/perry-migrate` (11 sites) is writer #2, already excluded by row 11a; and **`bin/perry-lint:3512`** uses it as a read-only skip predicate (*"the conformance record is Perry's own bookkeeping and deliberately not a `files[]` entry, so the loop below cannot see it"*). An earlier draft of this document said "no other file names `CONFORMANCE_FILE`", which is false | no third writer exists — but on a static argument, backed by row 1's empirical result that `perry-lint` leaves the file unchanged |
+| 12 | **the misparse hypothesis** (a line that is not a declaration read as one, then materialised by `render()` rebuilding the whole file) | parsed the *actual* pre- and post-episode files: 23 and 24 declarations, **0 unreadable**, every key resolving to a real file, and `render(read_conformance(f).declarations)` **byte-identical** to `f` in both cases. **This is the row that carries the elimination**, and it carries it for the whole class rather than for a list of examples: if any line in the file parsed to a declaration it should not have, `render(parse(f))` would differ from `f` — either by emitting a row that is not in `f`, or by rewriting the decorated line into canonical form. It differs by nothing. `render` is a fixed point on both actual files, so no misparse of any shape was present to be materialised | eliminated, for the class |
+| 13 | the misparse hypothesis, by example | appended each known trap to the real file and re-parsed: bolded `\| **File** \|` header, blockquote legend line, `\|---\|` separator, plain header, a bullet that looks tabular — all five produce no new declaration. **These five are examples, not a proof, and an earlier draft of this document wrongly generalised them into "the TASK-050 fixes hold".** Three further shapes do *not* pass — see § *The decoration-laundering class* | inconclusive on its own; superseded by row 12 |
+| 14 | the full test suite writing into the real root | *timing*: the background suite (`unittest discover`, started 10:11:48, backgrounded at 10:21:48) flushed its `tail -20` between 10:22:43 and 10:22:51 — **90 s before reading 1**, so it cannot explain a change after it. *Empirically*: re-run in the sandbox with md5 before/after (below) | eliminated on both |
+| 15 | a second background task | `bmx36hufh.output` in the session's `tasks/` dir looked like one. It is not: it is 0 bytes, its mtime is the timestamp of the `ls` that observed it, it never appears in a "moved to the background" result, and ten minutes later it is gone and replaced by `bima6r1r7.output` with the same signature. It is the harness's own output file for the in-flight foreground command | not a task |
+| 16 | a concurrent agent session | scanned **every** transcript on the machine — all projects, all subagent files — for the window 10:24:19Z–10:30:42Z. Two sessions were alive: `5bf5be56` in `/Users/bytedance/proj/Perry` (16 tool calls, all listed, all in rows 1–10 above) and `23a7e597` in `/Users/bytedance/proj/aimark` (39 tool calls, all CSS edits under its own root). Nothing else ran | eliminated |
+| 17 | a hook | `~/.claude/settings.json` registers `Notification`, `Pre/PostToolUse`, `Stop`, `SubagentStop`, `SessionEnd`, `UserPromptSubmit` — all pointing at `crew-hook.sh` and aimark's `session-hook.ts`. Neither names Perry. The `Stop`-hook theory also fit episode 1's 16-minute idle gap suspiciously well, which is precisely why it had to be checked | eliminated |
+| 18 | `bin/perry-knowledge`, `bin/perry-task` | as the spec had it — confirmed, and row 9 above runs them | eliminated |
+| 19 | *the two readings read different files* (a `--root` / cwd / `PERRY_PROJECT` skew, so the reader "changed its mind" without the file changing) | both invocations are `… perry-conform status --root .`, and both transcript entries carry `cwd: /Users/bytedance/proj/Perry`. This was the strongest no-write hypothesis and it dies on the reproduction: the file's bytes at reading 2 are reproduced exactly by one `declare`, so the file did change | eliminated |
+
+## Baselines
+
+Named by runner **and** tree, per `work/reference/review-constraints.md`.
+
+| tree | runner | modules | tests | failures |
+|---|---|---|---|---|
+| `wt-226` @ `ee0b36a` (this branch — **no code change**, the only file added is this one) | `bash tests/run` | **98** | **2882** | **3**, in 2 red modules |
+| sandbox: `git archive HEAD` of `ee0b36a` into a scratch dir | `python3 -m unittest discover -s tests` | — | **2882** | **6** (`failures=6, skipped=4`, 2376 s) |
+
+`bash tests/run` on `wt-226`, 711.5 s, 8 workers: `98 modules · 2882 tests`,
+`✗ 2 module(s) red` —
+
+- `test_diagnose.py` — `Ran 141 tests`, `FAILED (failures=2)`;
+  `TestUserLoadFindings.test_perry_itself_passes_its_own_id_checks`
+- `test_kr_progress_provenance.py` — `Ran 28 tests`, `FAILED (failures=1)`;
+  `TestBothOfTodaysWrongReadingsFlip.test_no_current_in_the_payload_claims_to_be_a_measurement`
+
+`unittest discover` on the sandbox: `Ran 2882 tests`, `FAILED (failures=6,
+skipped=4)` — the same 3, plus the 3 more the parallel runner does not surface:
+`test_diagnose.DecisionsAreCountedPerRecordNotPerMention.test_the_queue_register_reconciles_with_the_queue_on_this_repository`
+and three in `test_risks_store.TestTheReadersAreOneFunction`
+(`test_the_bullet_and_placeholder_rules_are_one_object`,
+`test_the_columns_are_one_list`, `test_the_register_header_predicate_is_one_object`).
+
+Both match the stated `main @ ee0b36a` baseline — 98 / 2882 / 3 under
+`tests/run`, three more under `unittest discover` — as they must: this branch
+changes no code.
+
+**`.perry/conformance.md` md5 before and after each run** — this is the
+empirical half of elimination #14, and the reason both runs were instrumented:
+
+| run | before | after |
+|---|---|---|
+| `bash tests/run` in `wt-226` | `ff66fbf343266a0f339fc48df8b0cd44` | `ff66fbf343266a0f339fc48df8b0cd44` |
+| `unittest discover` in the sandbox | `ff66fbf343266a0f339fc48df8b0cd44` | `ff66fbf343266a0f339fc48df8b0cd44` (25 rows → 25 rows) |
+
+The suite does not write the tree it runs in.
+
+Every write-side command in this investigation was run against the sandbox or
+`wt-226`. **Nothing was run against `/Users/bytedance/proj/Perry`** — the tree
+the row appeared in is byte-for-byte as this investigation found it.
+
+## Mutations
+
+**None, and that is the finding.** There is no fix to mutate. The code did
+exactly what its docstring says: one writer, called with one argument, wrote one
+row. A mutation here would have to redden a test for behaviour that is correct.
+
+The V4 bar for this row is the spec's third clause — *"the row closes on the
+written explanation, not on 'did not recur'"* — and it is met by the byte-identical
+reproduction above, not by an absence.
+
+The nearest thing to a mutation here is row 12's fixed-point check, and it does
+behave like one: perturb the input by a single decorated row and
+`render(parse(f)) == f` goes false. That is what makes it a detector rather than
+a sample, and it is why the elimination survived a correction that invalidated
+row 13's five examples.
+
+## What remains unexplained — nothing about the write, everything about the record
+
+The write is fully explained. **The record's inability to explain it is not.**
+
+Reconstructing a four-line change to the file that gates every write under
+`enforce` required: three agent transcripts, a machine-wide scan of every
+session on the host, the harness's background-task directory, and finally the
+user's `~/.zsh_history`. **None of that is Perry.** Inside Perry there was
+nothing to find, for the three reasons stated at the top of this document — a
+date-only `Declared` cell, no actor column, and no event ever written — plus a
+fourth that hides the evidence after the fact: `render()` rebuilds the whole
+file from the declarations dict on every write, so neither the file's mtime nor
+its content carries any trace of *which* row was the new one, and `git diff`
+cannot separate a row added at 09:19 from one added at 10:25.
+
+This is **TASK-234**'s case, and this row is now evidence for it rather than a
+duplicate of it. TASK-234 is blocked on TASK-050 and was not touched here; the
+format was not converted. The finding to carry forward is narrower than "add
+provenance": *the record cannot distinguish two invocations made on the same
+day, and cannot name the actor of either* — and a gate whose record cannot
+order its own rows will produce this same false alarm again.
+
+And it *will* recur, because the design guarantees a steady supply of exactly
+this event. `SKILL.md:197` forbids the agent from declaring on the user's
+behalf, and `perry-conform status` ends every run by printing the command the
+user should type. `bin/README.md:235` already writes the consequence down:
+*"every new file is born undeclared, in a new project and an old one alike …
+so the first `perry-task add` on a project Perry itself just wrote asks the
+user for one command. This is not confined to first runs."* **The design makes
+the user a writer, deliberately and often — and the record has no column for
+them.** Every hand-typed declaration is a write the agent cannot see, on the
+file that gates every other write.
+
+### The decoration-laundering class — corrected, and not inert
+
+An earlier draft of this document reported one shape here (a **bolded** path
+cell) and called the class *"inert … never affects a verdict"*. **That is true
+of asterisks and false of the class.** The V4 review ran seven more shapes and
+found three that are not inert; they are reproduced below on a sandbox copy,
+appending one row for a real, genuinely undeclared file to the reading-1 file:
+
+| shape of the path cell | parses to the plain key? | effect |
+|---|---|---|
+| `` \| `knowledge/…/linkage-graph-before-first-add.md` \| `` — **backticked** | **yes** | flips the file `undeclared` → **`conformant`** |
+| `  \| knowledge/…md \| …` — **indented two spaces** | **yes** | same |
+| the row inside a ```` ``` ```` **fenced block** | **yes** | same |
+| `\| **knowledge/…md** \|` — bolded | no (key keeps its asterisks) | inert |
+
+`read_conformance` strips with ``strip("` ")``, and `_CONFORMANCE_ROW` is
+`^\s*\|(?!\s*-)(.+)\|\s*$` — leading whitespace is consumed by `^\s*` and
+backticks by the `strip`, so all three decorated forms yield **the same key a
+plain row yields**. The parser has no notion of a fenced block at all.
+
+**And the decoration does not survive to be noticed.** `render()` rebuilds the
+whole file from the parsed declarations, so the next legitimate
+`perry-conform declare` — for any unrelated file — **launders the decorated row
+into a plain canonical row**, indistinguishable from one a person typed on
+purpose. On the file that gates every write under `enforce`. Only asterisks are
+inert, and only because they survive the `strip` and so can never match a
+`state_files()` key.
+
+**None of this changes TASK-226's conclusion, and the reason is row 12, not
+row 13.** The reading-1 and reading-2 files were parsed as they actually were:
+0 unreadable rows, and `render(parse(f))` byte-identical to `f` in both cases.
+That fixed-point check is a **complete detector for this entire class** — a
+laundered or launderable row cannot be a fixed point, because either the parse
+drops it or the render rewrites it — and it passed on both files. So no
+decorated row was present, and the observed command remains the only available
+explanation. The five traps in row 13 were the weaker argument; the fixed point
+is the one that holds.
+
+**Filed as its own row by the PMO; deliberately not fixed here.** It is
+`viewer/parsers.py § read_conformance`, shared with TASK-050's author, and it is
+not this defect — the phantom row's path cell was plain.
+
+## Recommendation for the board
+
+Close TASK-226 as **explained**: writer #1, run by the user at 10:25:11Z on
+2026-08-28, reproduced byte-for-byte. No third writer; no code change; the
+ADR-004 contract held.
+
+Carry the provenance finding to **TASK-234** with the sharper statement above,
+and consider — as a separate row, not this one — whether `perry-conform declare`
+should append to `.perry/events.jsonl`, which is the cheapest thing that would
+have made this a one-command answer.
+
+Two things came out of this row that are not this row, both already filed by the
+PMO and neither touched here:
+
+- **the decoration-laundering defect** in `viewer/parsers.py § read_conformance`
+  — a backticked, indented, or fenced path cell declares a real file, and the
+  next `declare` launders it into a canonical row. Measured above.
+- **the procedure**, § *The procedure that lesson is worth*. It belongs in a
+  reference page, not in an evidence file, if a session is ever to follow it
+  before asserting that nobody did something.

+# TASK-226 — V4 review
+
+**PASS**, with two required follow-ups. The conclusion is positively established, not
+merely fitted: I re-derived the epoch, re-read the cited history line, confirmed both
+readings and the 2-second prompt gap from the agent transcript independently of the
+author, and reproduced the disputed row byte-for-byte from a copy. The competing
+hypothesis that mattered — a misparse materialised by `render()` — **is** eliminated,
+by the fixed-point check in the author's row 12, which I reproduced.
+
+But the author's row 13 argues that elimination the wrong way, and in doing so
+**mis-scoped a live defect in the file that gates every write**. That is the most
+important finding below and it is not the row's conclusion; it is a new one.
+
+> Reviewed at `1823390`, tip of `coding/task-226-conformance-phantom`, in the
+> read-only worktree. Every write-side command in this review ran against
+> `git archive` copies under uniquely-prefixed `v4rev226-*` scratch directories.
+> Nothing was run against `/Users/bytedance/proj/Perry` or the reviewed worktree.
+
+---
+
+## 1. Timeline arithmetic — correct, to the second, with no timezone slip
+
+Converted independently, two ways (`datetime.utcfromtimestamp` and `date -u -r`):
+
+| epoch | UTC | +0800 |
+|---|---|---|
+| `1787912711` | **2026-08-28T10:25:11Z** | 18:25:11 |
+| `1787908775` | 2026-08-28T09:19:35Z | 17:19:35 |
+| `1787910107` | 2026-08-28T09:41:47Z | 17:41:47 |
+
+All three match the RESULT exactly. No off-by-one-hour error: the author reports UTC
+and labels it UTC, and the +0800 rendering is also correct.
+
+**The cited history line is real and verbatim.** `~/.zsh_history` line 3763 is exactly
+the line quoted in the RESULT, and it matches the `EXTENDED_HISTORY` shape
+`^: <10-digit epoch>:<elapsed>;<cmd>`. Per scope I confirmed the format and this one
+line only; I did not read any other history content.
+
+**Both readings check out against the transcript, which I read myself** rather than
+taking the author's table. From
+`~/.claude/projects/-Users-bytedance-proj-Perry/5bf5be56-81a2-4649-9858-ebc479bbd893.jsonl`:
+
+| claimed | actual | ✓ |
+|---|---|---|
+| reading 1 @ 10:24:19 | `2026-08-28T10:24:19.530Z` — `perry-lint … ; perry-conform status --root .` | ✓ |
+| user's shell declare @ 10:25:11 | `1787912711` = 10:25:11Z | ✓ |
+| next user prompt 2 s later | `2026-08-28T10:25:13.205Z` — `/perry decide rfc close-phase` | ✓ (2.2 s) |
+| DESIGN-012 heredoc @ 10:30:08 | `2026-08-28T10:30:08.326Z` | ✓ |
+| reading 2 @ 10:30:42 | `2026-08-28T10:30:42.309Z` — `perry-conform status --root .` | ✓ |
+
+The gap from reading 1 to the shell command is 51.5 s — "52 seconds" is right.
+
+I also enumerated **every** agent event in the 10:24:19 → 10:30:42 window rather than
+only the conformance-related ones. The complete set is: a read-only `git diff` in the
+skills dir, `perry-update-check`, `perry-state --json`, `perry-state --section design`
+(×2), several `cat`/`grep`/`sed` reads, one `AskUserQuestion`, and the DESIGN-012
+heredoc. That matches the author's row list with nothing left over. Their row 7 flags
+`perry-update-check` as "not considered by the spec" — that is correct and a good
+catch; it is genuinely there at 10:25:19 and the spec's window list omits it.
+
+## 2. Is the cited command the one that produces THAT row? — yes, byte for byte
+
+Run in a `git archive` copy (`v4rev226-sbx`), with the row removed to recreate the
+reading-1 state:
+
+```
+md5 before: 6804a7845cfa71ed0fe01fca2a650d75      (== the author's reported md5-before)
+$ perry-conform declare knowledge/goals/linkage-graph-before-first-add.md --root .
+  ✓ declared … at shape version 2
+line 31: | knowledge/goals/linkage-graph-before-first-add.md | 2 | 2026-08-30 | declare |
+```
+
+Shape version `2` and route `declare` are both produced by that command, and the row
+lands at line 31 — the same line the real file carries it on. With only the date cell
+normalised from today back to `2026-08-28`:
+
+```
+normalised md5 : ff66fbf343266a0f339fc48df8b0cd44
+git show ee0b36a:.perry/conformance.md | md5 : ff66fbf343266a0f339fc48df8b0cd44
+git show 2e41336:.perry/conformance.md | md5 : ff66fbf343266a0f339fc48df8b0cd44
+diff → identical
+```
+
+The author's headline md5 is real and I reproduced it from scratch. `.perry/conformance.md`
+has exactly one commit since 2026-08-27 (`2e41336`), so the committed file *is* the file
+at reading 2 — the comparison is against the right target.
+
+### The one number that did not reproduce, and why the author is nonetheless right
+
+The RESULT reports reading 1 as `23/24` and reading 2 as `24/25`, matching the
+observation. **My first run gave `22/23` and `23/24`** — one lower in both cells. I
+chased this to the end rather than waving it through, because a total that only matches
+the observation in the author's terminal would be the whole review.
+
+Cause: `perry-conform`'s enumeration is `state_files()`, which filters by
+`spec_claims` against the *installed skill's* `schema/state-schema.json` — not against
+anything in the project. Commit `0179c02` in `~/.claude/skills/perry`
+("TASK-235: DECISIONS.md stops existing"), merged at `8d81a9f` on **2026-08-30 00:42
++0800**, removed the `DECISIONS.md` file spec from the schema. The author ran on
+2026-08-29; I ran after that merge. `perry/DECISIONS.md` is still present and still
+declared in the record, but is no longer enumerated, so both cells drop by one.
+
+Re-running the whole reproduction against a copy of the skill at `0179c02^`:
+
+```
+READING 1  → 23/24 declared and matching
+declare    → ✓
+READING 2  → 24/25 declared and matching
+```
+
+**The author's totals are measured, not carried, and were correct when measured.** This
+also means the RESULT's reproduction is no longer replayable with the current install —
+worth a line in it, but not a defect in the finding.
+
+## 3. Eliminations — by experiment or by grep?
+
+The commit message claims *"every other path is eliminated by experiment rather than by
+grep."* **That claim is overstated.** The RESULT's own table contradicts it:
+
+- **Row 11 is a grep.** "`declare()` has exactly two call sites … `render()` has exactly
+  one caller … `P.Declaration(` is constructed in exactly two places" is a source sweep,
+  not an experiment. I re-ran it and every count is correct: `declare()` at
+  `bin/perry-conform:594` and `bin/perry-migrate:1874`; `render()` called only at
+  `bin/perry-conform:474`; `Declaration(` constructed only at `bin/perry-conform:469`
+  and `viewer/parsers.py:433`.
+- **Row 11's last clause is wrong**: *"No other file names `CONFORMANCE_FILE`."*
+  `bin/perry-lint:3512` names it. It is a read-only skip predicate — the conformance
+  record is excluded from lint's file loop — so the substantive conclusion (no third
+  writer) survives, but the stated fact does not.
+- **Row 11a** is eliminated by the record (`route` cell reads `declare`, and
+  `perry-migrate` passes `route="migrate"` — I confirmed this at `bin/perry-migrate:1876`).
+- **Row 19** is eliminated by reasoning plus the reproduction.
+
+Rows 1–10 and 12–18 genuinely are experiments. So: most paths are experimental, the
+third-writer path is not, and the commit message should say so.
+
+### The misparse hypothesis — eliminated, but not by the argument given
+
+The author's **row 12** is the load-bearing check and it is correct. I reproduced it
+independently against the actual pre- and post-episode files:
+
+| file | declarations | unreadable | `render(parse(f)) == f` |
+|---|---|---|---|
+| pre-episode (reading 1) | 23 | 0 | **True** |
+| post-episode (reading 2) | 24 | 0 | **True** |
+
+That fixed point is a *complete* detector for the whole misparse class: any line that
+`read_conformance` invents a key from is emitted back by `render()` in canonical form,
+which cannot equal the non-canonical original. So no latent phantom was in that file,
+and the misparse route is closed for this episode. Good, and sufficient.
+
+The author's **row 13** then argues it a second, weaker way — five known traps, all
+inert, therefore *"the TASK-050 fixes hold."* I ran their five and confirmed all five
+are inert. **I then ran seven more, and three of them are not.**
+
+| trap appended to the real record | becomes a declaration? | `render()` emits |
+|---|---|---|
+| bolded `\| **File** \|` header | no | — |
+| blockquote legend | no | — |
+| `\|---\|` separator | no | — |
+| plain header | no | — |
+| tabular bullet | no | — |
+| prose sentence containing pipes | no | — |
+| non-numeric version cell | no (1 unreadable) | — |
+| bolded path cell (author's filed "observation") | yes, key `**knowledge/phantom.md**` | a **bolded** row — inert, as the author says |
+| **backticked path cell** | **yes, key `knowledge/phantom.md`** | **`\| knowledge/phantom.md \| 2 \| … \| declare \|`** |
+| **leading-whitespace row** | **yes, plain key** | **a plain row** |
+| **row inside a ` ``` ` fence** | **yes, plain key** | **a plain row** |
+
+`strip("` ")` removes backticks as well as spaces, `_CONFORMANCE_ROW` is `^\s*\|` so
+indentation is allowed, and `read_conformance` tracks no code fences. All three produce a
+**plain** path cell — the exact shape of the row this task was chartered to explain.
+
+## 4. The most important finding — a live hole the RESULT files as "inert"
+
+The RESULT's closing section files the asterisk case as *"one observation, not a
+defect … It is inert: no key from `state_files()` ever carries asterisks, so the row
+can never match a file, never affects a verdict."* That is true **of asterisks** and
+false of the class. Measured on a copy (`v4rev226-sev`):
+
+```
+baseline                        → knowledge/goals/linkage-graph-before-first-add.md · undeclared
+append  | `knowledge/goals/linkage-graph-before-first-add.md` | 2 | 2026-08-28 | declare |
+recheck                         → knowledge/goals/…-first-add.md · CONFORMANT
+status                          → 23/25 declared and matching
+then one legitimate declare of another file:
+line 31: | knowledge/goals/linkage-graph-before-first-add.md | 2 | 2026-08-28 | declare |
+```
+
+A single hand-written row with the path in backticks **flips a real file's verdict from
+`undeclared` to `conformant`**, and the next legitimate `declare` launders it into a
+plain, canonical, indistinguishable row. This is not inert and it is not confined to
+TASK-050's class.
+
+It is reachable by design, not by contrivance: the record's own header says *"Delete a
+row to withdraw a declaration,"* which invites hand editing, and backticks are how
+`perry-conform`'s own help text renders paths. This is the file that gates every write
+under `enforce`.
+
+**It did not cause this row** — row 12's fixed point proves no such line was in the
+pre-episode file, and I verified that. But the author had the mechanism in hand,
+tested one member of it, and generalised the wrong way.
+
+**Required follow-up 1**: file a row (`<TASK-ID>`) for `viewer/parsers.py §
+read_conformance` — a declaration key must be rejected unless the cell is already
+canonical, and fenced/indented lines must not be read as rows. Severity is above the
+asterisk observation: verdict-flipping, not inert.
+
+## 5. Falsifiability, and the claim that outlives the row
+
+**Overclaim.** *"One `perry-conform declare` with that one argument produces that exact
+file. **No other input produces it.**"* The second sentence is false, and my trap-7
+experiment is the counterexample: a backticked row plus any later declare produces the
+identical bytes. The first sentence is what the evidence supports; the second is
+rhetoric and should be cut.
+
+**Falsifiability**: the RESULT never states the counterfactual. Had `~/.zsh_history`
+been absent or unreadable, eliminations 1–19 plus the reproduction would still have
+established *"writer #1 ran, from outside every observed surface"* — a real and
+falsifiable conclusion. The RESULT does not say this, so as written the method reads as
+one that only terminates when it finds what it is looking for. It is better than that;
+it should say so.
+
+**The lesson** — *"the session read 'no `perry-conform declare` was run' off its own
+transcript, and its own transcript is not the machine."*
+
+- **(a) Correct.** Confirmed from the transcript: at 10:31:02–10:31:54 the original
+  session grepped `bin/perry-knowledge`, `bin/perry-task` and `bin/perry-conform` for
+  writers, and filed the intake row at 10:32:32 — it searched the code and its own
+  history, and never the host.
+- **(b) Not quite the root cause — the RESULT's own better answer is one section
+  lower.** The session could not have checked the machine from inside Perry even had it
+  thought to. I verified both supporting facts: `grep` for `events.jsonl` /
+  `append_event` / `log_event` in `bin/perry-conform` returns **nothing**, against 9
+  hits in `bin/perry-task`; and the record carries exactly **8** rows dated
+  `2026-08-28`, all route `declare`, with a date and no time and no actor column. The
+  provenance finding is the root cause; the transcript line is its symptom. The RESULT
+  ranks them the other way round in its headline.
+- **(c) No procedure attached.** The RESULT recommends a *fix* (have `declare` append to
+  `.perry/events.jsonl`, as a separate row) but states **no rule for a session**. The
+  operational lesson — *when a state file changes with no cause in the transcript, the
+  transcript cannot clear the host; check it or record the question as open, do not
+  conclude a third writer* — is exactly what would have prevented this row and the two
+  earlier episodes, and it appears nowhere as guidance. As written it is prose.
+
+**Required follow-up 2**: attach that procedure, or file it, before the row closes.
+
+## 6. Also checked
+
+- **No code change — confirmed.** `git diff --name-status ee0b36a HEAD` is a single
+  `A perry/evidence/2026-08/TASK-226-result.md`, 258 insertions. `git status --porcelain
+  --untracked-files=all` is empty. Nothing was quietly touched.
+- **Numbers nobody measured** — one hole, minor. The RESULT's own instrumentation table
+  leaves the `unittest discover` sandbox "after" cell as *"(recorded with the run)"* —
+  i.e. the empirical half of elimination #14 is asserted but its result is not written
+  down. I filled it in myself; see below. Everything else I checked was measured:
+  md5s (all three verified), the 8-row count, the failure counts, the totals (§2).
+- **Baseline — stated by board state, as asked.** On a **`git archive` copy of branch
+  HEAD `1823390`** (not the live board): **98 test modules**; `test_diagnose.py` runs
+  141 tests, 2 failures; `test_kr_progress_provenance.py` runs 28 tests, 1 failure —
+  **3 failures in 2 red modules**, matching the author's table and the stated `main`
+  archive-copy baseline. I did not re-run all 2882 tests to a count; the branch changes
+  no code, and the two named red modules reproduce exactly. Both named failing tests are
+  the ones the author names.
+- **`.perry/conformance.md` is not written by the suite — I filled in the author's
+  blank cell.** Full `python3 -m unittest discover -s tests` on the archive copy of
+  branch HEAD, instrumented:
+
+  ```
+  MD5-BEFORE: ff66fbf343266a0f339fc48df8b0cd44
+  MD5-AFTER : ff66fbf343266a0f339fc48df8b0cd44
+  ```
+
+  Stronger than "unchanged": the run's own output shows the suite *does* exercise
+  `declare` and `migrate` and *does* write conformance records — every one of them into
+  a `tmp*` root under `/private/var/folders/…`, none into the project root. Elimination
+  #14 is now empirically complete, not just asserted. (I truncated stdout to the tail,
+  so I do not have the suite's own `Ran N tests` total from this run; the 3 failures are
+  verified directly from the two named modules above.)
+
+## Not checked / still open
+
+- **The two earlier history lines** (`1787908775`, `1787910107`). Their epochs convert
+  correctly, and the record independently corroborates 8 rows dated 2026-08-28. I did
+  **not** open those history lines: scope limited me to line 3763. The two earlier
+  episodes are therefore corroborated arithmetically and by row count, not by direct
+  reading.
+- **The machine-wide transcript scan (row 16)** and the **hook scan (row 17)**. I
+  verified the two readings and the full window in the Perry session's own transcript,
+  but did not re-scan every project's transcripts on the host or re-read
+  `~/.claude/settings.json`. Taken on the author's word.
+- **`perry/DECISIONS.md` is declared in the record but is no longer a state file** —
+  `perry-conform check DECISIONS.md` answers `absent`, after TASK-235 removed its
+  schema spec. Noticed in passing while chasing §2. Out of scope for this row; may
+  deserve its own look, since a declared row for a file the tool no longer enumerates
+  is a silent orphan in the gate record.
+
+## Verdict
+
+**PASS.** The conclusion follows from the evidence and every competing hypothesis I
+could construct is closed:
+
+- *third writer* — closed by the call-site sweep (grep, and I re-ran it), corroborated
+  by the reproduction;
+- *`render()` materialising an extra key from a misparse* — closed by the render
+  fixed-point on both actual files, which I reproduced, and which covers the traps the
+  author did not test;
+- *`perry-migrate`* — closed by the `declare` route cell;
+- *the two readings read different files* — closed by the byte-identical reproduction;
+- *the suite writing the tree* — closed by timing and by md5 before/after, which I
+  re-measured.
+
+Open against the RESULT, none of which overturns it: an unsupported "no other input
+produces it"; a mis-scoped defect filed as inert that is in fact verdict-flipping
+(follow-up 1); a lesson with no procedure (follow-up 2); a commit message that claims
+no greps where there is one; a wrong sub-claim about `CONFORMANCE_FILE`; a blank
+measurement cell; and a reproduction recipe that no longer replays against the current
+install.

+# TASK-227 — result: a declaration of drift is validated at both ends
+
+> Branch `coding/2026-08-29-overnight-batch`, commit `1fb2324`. Rung **V3**.
+> Measured 2026-08-29.
+
+## The defect
+
+`perry-goals link --unlinked <TASK-ID>` records that a **known** row serves no
+KR. It validated nothing, and `perry-lint` did not check `unlinked[]` either.
+On 2026-08-28 two malformed declarations went into `phase/003-linkage.md` and
+the lint reported **0 errors** over both:
+
+1. the literal string `NOT-A-TASK-ID at all`
+2. **48 task ids space-joined into one argument**
+
+The second is the one that matters. It is not a typo — it is the ordinary way
+this command gets called, from a loop, in a shell with word splitting off. The
+whole sweep landed as a single list entry while the command reported success 48
+times. The repair was one hand edit back to `unlinked: []` followed by 48
+re-runs, recorded in `journal/2026-08/2026-08-28.md § OKR attribution sweep`.
+
+## Two checks, two different questions
+
+| | asks | severity |
+|---|---|---|
+| the **writer** | is this ONE handle, with no whitespace? | refusal |
+| the **linter** (`linkage-unlinked-exists`) | does a row with this id exist? | `warn` |
+
+**A store lookup at the writer would not have caught the case that happened.**
+Every id in that 48-id blob existed. Whitespace is the only thing that
+distinguishes 48 valid ids from one.
+
+**And the store question cannot live at the writer**, because it would make a
+declaration unwritable the day `perry-task purge` removes the row it names. It
+sits at `warn`, matching `linkage-task-exists` — the same statement one key
+over — so a stale declaration is a record to correct rather than a file to
+refuse.
+
+Why an unchecked declaration is not free: `perry-state --section attribution`
+reports `declared_unlinked` straight off this list (TASK-228), so an id no row
+carries is a row the standup reports as **answered** when no such row exists to
+have answered for.
+
+## Verification
+
+**Shown able to go red**, each mutation restored byte-identical (`md5` checked):
+
+| mutation | result |
+|---|---|
+| remove the whitespace guard | 3 failures |
+| remove the shape check | 1 failure |
+| remove the linter sweep | 2 failures + 1 error |
+
+`tests/test_unlinked_declaration.py` — 11 tests. The linter half needs a fixture
+**with** a store: the sample project ships without `tasks.jsonl`, and the sweep
+is correctly silent then. That is the same rule
+`test_linkage_task_exists § TestNoStoreIsSilent` pins — absence is not "every
+declaration dangles", which was TASK-117's inversion — and it is asserted in
+both directions here.
+
+`perry-lint --root .` on the live project reports **0**
+`linkage-unlinked-exists` findings: all 52 declared ids resolve to records.
+
+**Suite**: 3 modules red before and after under `bash tests/run`. This change
+adds none.
+
+## One note on method, because it nearly produced a false green
+
+The refusal tests initially passed for the **wrong reason**. The copied fixture
+is undeclared, so ADR-004's conformance gate refused every write before
+`link_unlinked` was ever reached — `assertNotEqual(returncode, 0)` went green on
+a refusal that had nothing to do with this row.
+
+It was caught by the one test in the module that expects a **success**. The
+fixture now opts out through `tests/gate.py`, and every refusal test asserts on

+# TASK-228 — result: the three attribution buckets are disjoint
+
+> Branch `coding/task-228-attribution-buckets`, commit `2b01253`. Rung **V3**.
+> Measured 2026-08-29.
+
+## The defect
+
+`bin/perry-state` built `unlinked` by asking *"did this row resolve to a KR?"*
+That is false for a **declared** row as much as an undeclared one, so every id
+in the register's `unlinked[]` was reported in both `unlinked` and
+`declared_unlinked`.
+
+Measured 2026-08-28 on Perry's own board after 48 rows were declared:
+`linked=8, unlinked=48, declared_unlinked=48`, and the two sets were
+byte-identical.
+
+## Why it was not cosmetic
+
+`unlinked` is the number the standup renders as *"N tasks awaiting KR
+attribution"*.
+
+**On 2026-08-29 this session read that number off the payload and reported to
+the user that 52 rows owed an attribution answer. The true never-asked count
+was 0.** Every one of those answers had been given the day before, through
+`perry-goals link --unlinked`, with the user's own consent recorded in
+`journal/2026-08/2026-08-28.md § OKR attribution sweep`. The payload turned
+finished work back into outstanding work, and the person it misinformed was the
+person who had done the work.
+
+The correction was made by computing the set by hand — open `main`-track rows
+minus linked minus declared — which is exactly the arithmetic the payload is
+supposed to save a reader from doing.
+
+## The fix
+
+Both halves of the deliverable, which named the payload *and* the page:
+
+- `bin/perry-state`: a row named in the register's `unlinked[]` is reported in
+  `declared_unlinked` and **nowhere else**. `unlinked` is now the NEVER-ASKED
+  set.
+- `reference/okr-linkage.md`: the partition is stated explicitly. The page
+  already distinguished *"`unlinked` (couldn't resolve)"* from
+  *"`declared_unlinked` (the graph says outright that this work serves no
+  KR)"* — it described three states while the code implemented two. Nothing
+  enforced the agreement, which is how they drifted.
+
+This is also what makes `P003-O3-KR1` measurable: that KR counts *"open
+`main`-track rows in neither `objectives[].krs[].tasks[]` nor a declared
+`unlinked[]`"*, and a bucket that folds the declared into the unresolved makes
+the KR unmeasurable from the payload it is defined against.
+
+## Verification
+
+**The row's own Verification, run:** *"After the fix, `unlinked` must be 0 for
+that same state. Mutation: leave one row undeclared and it must appear in
+`unlinked` and nowhere else."*
+
+```
+linked            : 7
+unlinked          : 0   []
+declared_unlinked : 52
+```
+
+Both halves hold. `TestDeclaringARowMovesItBetweenBuckets` runs the mutation in
+both directions on a copied fixture.
+
+**Shown able to go red.** Deleting the `elif t.id in declared_unlinked` branch
+→ 4 failures in `tests/test_attribution_buckets.py`. Restored, green.
+
+**Suite**: 3 modules red before and after (`test_contract_key_parity` 2,
+`test_diagnose` 2, `test_kr_progress_provenance` 1) — all pre-existing on
+`main`, baselined in the same worktree. This change adds none.
+
+## Two shipped tests converted, and what they revealed
+
+- `tests/test_parsers.py::test_unlinked_task_is_surfaced_not_guessed` pinned
+  `unlinked == ["REL-009"]` for an id the fixture **declares**. It now asserts
+  the row is surfaced in `declared_unlinked` and never guessed into a KR —
+  which is what the test is named for.
+- `tests/test_linkage_writer.py::test_a_declared_unlinked_task_stops_being_drift_when_it_is_linked`
+  carried a docstring ending *"and must not be reported as both afterwards"*
+  directly above two assertions pinning the row into both buckets
+  **beforehand**. The double-count had been seen and tolerated one line from
+  the sentence objecting to it. Its actual subject is unchanged.
+
+## One note on method
+
+The first draft of `tests/test_attribution_buckets.py` hand-built a board and a
+linkage register. It parsed **zero** rows, and every disjointness assertion
+passed vacuously over two empty sets. The module now copies
+`tests/fixtures/sample-project`, which already carries the shape under test,
+and `TestTheFixtureIsTheShapeUnderTest` is the control that makes that failure
+mode loud instead of silent.

+# TASK-229 — result: *no store* and *clean* are six different answers, measured
+
+> Serves **P003-O1-KR3** (`perry/phase/003-storage-code.md`): *stores that report
+> `unchecked` rather than `clean` when the store file is removed, **measured by
+> removing each one***. Target **6 of 6**, baseline **2 of 6**.
+>
+> Measured 2026-08-29 by the PMO. Rung **V3**.
+
+## How it was run
+
+The spec declares `Executor: manual — the procedure removes state files. It is
+safe only against a scratch copy.` That instruction was followed literally: the
+repository was copied to a scratch tree and **every removal below happened
+there**, never in `/Users/bytedance/proj/Perry`.
+
+```
+rsync -a --exclude .git --exclude __pycache__ --exclude 'worktree*' \
+  /Users/bytedance/proj/Perry/ <scratch>/t229/
+cd <scratch>/t229
+```
+
+Each store was moved aside with `mv <store> <store>.bak`, `python3 bin/perry-lint
+--root .` was run, and the store was moved back before the next one. The lines
+below are that command's actual output, filtered to the census, not a summary.
+
+## Baseline — every store that exists, in place
+
+```
+  · store: 225 record(s), 0 row(s) drifted
+  · risks store: 4 record(s), 0 risk(s) drifted
+  · no `intake.jsonl` — drift against the intake store is unchecked, not clean
+  · no `asks.jsonl` — drift against the ask store is unchecked, not clean
+  · OKR store: 36 record(s), 0 row(s) drifted
+  · config store: 9 record(s), 0 row(s) drifted
+```
+
+Six declared projection stores, six lines. `intake.jsonl` and `asks.jsonl` are
+absent on this project today — they are the two the baseline already counted,
+and they are re-measured below rather than assumed.
+
+`.perry/events.jsonl` is a seventh declared `.jsonl` in `claims[]` and is **not**
+one of the six: it is the event log, derived and disposable, projected from
+nothing. The census is right not to carry a line for it.
+
+## The six removals, one quoted verdict each
+
+**1 · `perry/tasks.jsonl` removed**
+```
+  · no `tasks.jsonl` — drift against the store is unchecked, not clean
+```
+
+**2 · `perry/okr.jsonl` removed**
+```
+  · no `okr.jsonl` — drift against the OKR store is unchecked, not clean
+```
+
+**3 · `perry/risks.jsonl` removed**
+```
+  · no `risks.jsonl` — drift against the risks store is unchecked, not clean
+```
+
+**4 · `perry/intake.jsonl` removed** (already absent — the baseline case, re-read)
+```
+  · no `intake.jsonl` — drift against the intake store is unchecked, not clean
+```
+
+**5 · `perry/asks.jsonl` removed** (already absent — the baseline case, re-read)
+```
+  · no `asks.jsonl` — drift against the ask store is unchecked, not clean
+```
+
+**6 · `.perry/config.jsonl` removed**
+```
+  · no `.perry/config.jsonl` — drift against the config store is unchecked, not clean
+```
+
+## Verdict
+
+**6 of 6.** No store reports `clean` while absent. `P003-O1-KR3` is at target,
+and unlike its identically-numbered predecessor `P002-O1-KR3` — which scored
+0.33 because its metric said "reported" without saying by what — every one of
+the six numbers above is a removal that actually happened.
+
+The two answers stay textually distinct in both directions, which is what makes
+the check meaningful rather than tautological: a present store says
+`N record(s), 0 row(s) drifted`, an absent one says `unchecked, not clean`.
+Neither sentence can be mistaken for the other by a reader or by a grep.
+
+## Finding, filed rather than fixed here
+
+**The tasks store is the only one of the six whose census line does not name
+it.** Present, it reads `· store: 225 record(s)`; absent, `drift against the
+store is unchecked`. The other five all carry their name — `risks store`, `OKR
+store`, `config store`, `intake store`, `ask store`. On a six-line census the
+unnamed line is the one a reader has to count positions to identify, and
+`tasks.jsonl` is the store that matters most.
+
+This is a one-word defect in `bin/perry-lint` and it is **not** fixed in this
+row: TASK-229's deliverable is six measurements, and changing the string the
+measurement quotes in the same commit would leave the evidence above describing
+output that no longer exists. Filed to `## Intake`.

+
+## 0. The short version
+
+- **What the change is:** the parallel runner feeds its worker pool
+  longest-module-first instead of alphabetically. It reorders work. It does not
+  select, skip, delete or filter anything, and that property is now asserted
+  eight ways.
+- **What it buys, measured with load controlled:** the makespan drops **33-37%**
+  and lands on the theoretical floor. Serial `discover` 589.6s → parallel
+  **133-285s over seven runs, median 149.7s**, on the same machine in the same
+  hour; the spread is foreign load, and the whole range is quoted because the
+  fast end of it is not the number.
+- **Coverage:** the parallel id SET is **identical to the serial id set** —
+  2904 against 2904, zero on either side — and identical across all **twelve**
+  full runs. A V4 round re-derived that set from unittest's loader without
+  running a test or touching my parser and got **2907 against 2907** (§ 8a).
+  Eight mutations of mine, eight named tests reddened. On a quiet machine the
+  whole gate is **108.9s** (§ 8b).
+- **What I corrected in the inherited work:** its id extractor was silently
+  dropping 14 tests, and its docstring's headline measurements were not
+  reproducible and disagreed with the data file committed beside them.
+- **What the V4 round corrected in MINE**, all four recorded in place rather
+  than edited away: a guard I shipped **survived its own deletion** and I had
+  argued it was untestable (§ 6, now M6-M8); "the model is exact four times of
+  four" was really **two** (§ 3); an md5 named no committed file (§ 6); and my
+  own quoted range dropped my two slowest runs (§ 4.4).
+- **What does not hold:** the spec's "under two minutes" target is not
+  guaranteed, and cannot be by this approach — the spec also contradicts itself
+  on the point. Filed as **TASK-244**. See § 7 and § 8a.
+
+## 1. Conditions — stated first, because they are bad
+
+**The machine was not quiet at any point tonight.** Another agent's mutation
+harness and suite runs held the 1-minute load average between **17 and 65** on
+a 14-core box for the entire measurement window (02:28 was the only dip, to
+5.6). The task brief already recorded the same phenomenon from earlier in the
+day: 264s, 354s and 726s for the identical command within one hour.
+
+I saw the same thing. **The identical command, `python3 tests/parallel`, took
+133.1s and 285.0s tonight — a 2.1x spread with nothing changed.** A single
+timing here is not a measurement, and any number below that comes with either a
+run count or a note saying it is one sample.
+
+Machine: 14 cores, Python **3.11.15** at `~/.local/bin/python3` (the spec said
+3.9.6 Xcode; that is not what `python3` resolves to in this worktree, and the
+`(test_mod.Class.test_x)` id format the runner parses is 3.11's).
+
+Tree: git worktree at `coding/task-230-suite-cost`, committed state only — not
+the live dirty board of `/Users/bytedance/proj/Perry`.
+
+**And the tree is behind, and the number moves while you read it.** This branch
+forked at `ee0b36a`. `main` had moved **65 commits** when I first wrote this
+line, **66** when a V4 round checked it, and **67** by the time I corrected it —
+`main` is advancing during the session, so the figure is a timestamp, not a
+constant. My "65" was simply stale, and the reviewer's 66 was right when taken. The measured suite is 99 modules; `main` carries 100 at
+the time of writing, so **every number here describes this branch's tree, not
+current `main`'s**, and a merge will shift the totals by whatever `main` added.
+It will not shift the conclusions: the saving is a scheduling property of any
+module set with one dominant module, and `tests/durations.json` treats an
+unrecorded module as slow so a newly-merged one sorts first rather than last.
+`main` has touched none of the four files this branch changes
+(`tests/parallel`, `tests/run`, `tests/test_parallel_runner.py`,
+`tests/durations.json`) since the fork point, so the merge is expected clean —
+**expected, not verified; I did not merge.**
+
+## 2. Baselines I measured myself
+
+| what | wall | conditions |
+|---|---|---|
+| `python3 -m unittest discover -s tests -v`, serial | **589.6s** (`Ran 2904 tests`) | 02:18-02:28, load 31.3 → 5.6 |
+| `python3 tests/parallel` (longest-first), 7 runs | 133.1 · 140.1 · **149.2 · 149.7 · 171.9** · 247.0 · 285.0, **median 149.7s** | 01:55-02:40, load 21-65 |
+| `python3 tests/parallel --alphabetical`, 5 runs | 179.8 · 184.4 · **188.4** · 203.1 · 241.1, **median 188.4s** | interleaved with the above |
+| `bash tests/run`, full gate | **266.7s** | 02:45-02:50, load 25.7 → 59.1 |
+
+Every run was `--ids`-instrumented; every id file is in
+`scratchpad/m230/ids-*.tsv`.
+
+**Test counts.** 99 modules / **2904** tests at `78aa67e`, which is where the
+twelve measured runs were taken, and **2907** at `642e2ca` after the three tests
+§ 4.2's guard needed. The inherited docstring said 98 / 2882; the difference is
+the module that commit added plus the eight tests I added. `bash tests/run` and
+`discover -s tests` report the same number as each other — they run the same set
+(§ 5).
+
+**Red at baseline: five tests in three modules, deterministically, in all twelve runs**, none of
+them caused by anything in this row:
+
+- `test_diagnose.DecisionsAreCountedPerRecordNotPerMention.test_the_queue_register_reconciles_with_the_queue_on_this_repository`
+- `test_diagnose.TestUserLoadFindings.test_perry_itself_passes_its_own_id_checks`
+- `test_kr_progress_provenance.TestBothOfTodaysWrongReadingsFlip.test_no_current_in_the_payload_claims_to_be_a_measurement`
+- `test_contract_key_parity`'s two witness tests — the pair the brief names as
+  data-dependent on `conformance.in_progress_with_no_live_run` being non-empty.
+  **They passed in my first run at 01:52 and failed in all eleven after it,
+  including four alphabetical runs**, which is what rules the schedule out as
+  the cause: the flip happened between two runs of the *same* arm. Filed, not a
+  regression; and worth noting that whatever makes that collection non-empty is
+  time- or environment-driven and crossed its threshold at about 01:55.
+
+## 3. The A/B, with the load taken out of it
+
+Wall-clock under that much foreign load is not a measurement, so both schedules
+were also evaluated **against each run's own per-module costs**: for four
+`--times` runs, what would the *other* schedule have produced on exactly the
+module times that run observed? This removes load drift entirely, because both
+arms are scored on the same numbers.
+
+| run | schedule used | measured wall | simulated alphabetical | simulated longest-first | perfect knowledge | floor = max(longest, Σ/8) |
+|---|---|---|---|---|---|---|
+| t-alpha-1 | alphabetical | 179.8s | **179.7** | 120.1 | 120.1 | 120.1 |
+| t-hint-1 | longest-first | 140.1s | 222.9 | **140.0** | 140.0 | 140.0 |
+| t-alpha-2 | alphabetical | 241.1s | **241.1** | 155.4 | 154.5 | 154.5 |
+| t-hint-2 | longest-first | 133.1s | 210.4 | **133.1** | 133.1 | 133.1 |
+
+**The bolded cell is the simulation of the schedule the run actually used, and
+it reproduces that run's measured wall-clock to within 0.1s. But it is validated
+by TWO of these four runs, not four** — an earlier draft of this file claimed
+four and a V4 round was right to cut it in half.
+
+In the two **longest-first** runs the longest module started at t=0 and ran to
+the end, and `Σ/8` is below it, so `simulated = max(module time) = measured
+wall` is forced. It is an arithmetic identity restating the run's own longest
+module back at itself, and it predicts nothing.
+
+The two **alphabetical** runs are the real check. There the makespan is a
+bin-packing of 99 modules across 8 workers under an order that has nothing to do
+with cost — it could have landed anywhere between `max` (120.1s, 149.2s) and
+`Σ` — and it landed on **179.7 against a measured 179.8**, and **241.1 against a
+measured 241.1**. Two independent predictions, both right to 0.1s. That is the
+reason to believe the other column, and two is the honest count.
+
+Reading it: the saving is **33-37%**, and longest-first lands exactly on the
+floor — it is not merely better than alphabetical, it is optimal for this module
+set, equalling the perfect-knowledge schedule in three runs of four and losing
+0.9s in the fourth.
+
+**Total CPU is unchanged**, which is the check that the saving is scheduling and
+not lost work: `user+sys` came to 501.3s and 500.5s in the two alphabetical
+runs, 475.8s and 482.6s in the two longest-first ones. Same work, finishing
+sooner, with slightly less contention overhead.
+
+## 4. What I changed, and why each piece is safe
+
+### 4.1 Inherited, verified, kept: longest-first scheduling
+
+`schedule()` is `sorted(mods, key=...)`. It is a **permutation** of the glob's
+own result — same length, same membership — under every way the hint can be
+wrong. That is the whole safety argument, and it is asserted directly (six
+tests: absent hint, stale names, partial hint, full hint, garbage that does not
+parse, wrong types) plus one that runs the property against the live module set
+and live hint. Mutation M5 below proves those assertions are not decorative.
+
+`tests/durations.json` is read only as a sort key. Its committed values are 3-4x
+too large — they were recorded under the same foreign load — and it **still**
+produces the optimal schedule, because only the order of the values matters.
+That is the design working, so I did not refresh it.
+
+### 4.2 Corrected: `--ids` was silently dropping tests
+
+`--ids` is what the spec makes the gate — *"the sharded run must produce the
+identical set"*. The inherited `parse_ids` required unittest's verdict to sit at
+the end of the line naming the test. It does not, whenever the test writes to
+stderr: unittest prints ` ... ` when the test **starts**, so the test's own
+output lands in between and the verdict is pushed onto a line of its own.
+
+Measured on the live suite: **unittest ran 2899 tests and the id parser
+accounted for 2885.** Fourteen missing across seven modules —
+`test_events_feed`, `test_live_state_expectations`, `test_migrate`,
+`test_one_header_rule`, `test_one_startable_rule`, `test_shipped_vocabulary`,
+`test_stranded_rows` — every one of them lost to an ordinary
+`DeprecationWarning` line.
+
+This is the defect `tests/parallel` already carries a scar from, reappearing in
+the function whose entire job is to say which tests ran: **the number was still
+large enough to look right**, 99.5% of it. And it is worse than an undercount,
+because a set that understates turns *"a test stopped running"* into *"the
+parser never saw it"* — a false negative in the exact comparison this row exists
+to make.
+
+Fixed two ways:
+
+1. `parse_ids` reads a verdict alone on a line, and does not let one test's
+   stderr bleed a verdict onto the next test.
+2. **`--ids` refuses to write a file it cannot account for.** `ran` comes from
+   unittest's own `Ran N`; the ids come from parsing the verbose stream. Two
+   numbers with independent origins that must agree. A third output shape is
+   always possible (a test whose output has no trailing newline glues the
+   verdict onto it), and a parser that cannot account for every test must say
+   so rather than round down.
+
+The guard is enforced **only under `--ids`** — deliberately. That is the mode
+whose entire output is the set; a run asked only for a verdict is not made red
+by a line the parser could not read. The trade-off is stated rather than hidden:
+a future unparseable shape will fail `--ids` runs and be invisible to plain
+ones.
+
+### 4.3 Added: `--alphabetical`
+
+Reproduces the exact pre-TASK-230 schedule so the claimed saving can be
+re-measured instead of believed, and is asserted to be `sorted(glob)` rather
+than an approximation of it. This is what made § 3 possible.
+
+### 4.4 Corrected: the docstring's measurements
+
+The inherited docstring claimed *"446.3s alphabetical → 322.1s longest-first at
+8 workers"*, per-module costs of 322s / 282s / 234s, and a makespan of 322.1s at
+8, 12, 14 and 16 workers alike. **I could not reproduce any of it**, and it
+disagrees by 2x with `tests/durations.json`, which was committed in the same
+change (that file records 567 / 549 / 464 for the same three modules). Both were
+presumably taken under different amounts of foreign load, which is the point of
+§ 1. Replaced with the twelve runs above, each with its conditions.
+
+Also corrected: 99 modules / 2904 tests (not 98 / 2882), alphabetical positions
+91 / 84 / 85 of 99 (not 90 / 84 / 83 of 98), and `tests/run`'s header comment,
+which still described a 34-module 181s suite.
+
+**And then corrected again, by a V4 round, in the same direction.** My own
+replacement docstring quoted the parallel range as "133-150s" — which is my two
+fastest runs of seven, with the 247.0s and 285.0s dropped. A range that excludes
+the slow half of the measurements is not the range, and quoting it was the same
+optimism I had just finished criticising. Both `tests/parallel` and `tests/run`
+now say **133-285s, median 149.7s of seven runs**, with the spread attributed to
+machine load. The reviewer's own independent run came in at 246.8s, inside the
+honest range and outside the one I published.
+
+### 4.5 Nothing was deleted, skipped or made conditional
+
+No test was removed, no test was marked skip, no assertion was weakened, no
+module was excluded, and no timeout was shortened. The id-set equality in § 5 is
+the mechanical proof of that, not a promise.
+
+## 5. Does the change alter which tests run under which runner?
+
+**No — and I measured the pre-existing disagreement rather than repeating it
+from the brief.** Comparing the serial `discover -s tests` id set against a
+longest-first parallel run:
+
+```
+serial parsed ids: 2904   (unittest itself said: Ran 2904 tests)
+parallel ids:      2904
+only in serial:    0
+only in parallel:  0
+outcome differs:   3
+  test_risks_store.TestTheReadersAreOneFunction.test_the_bullet_and_placeholder_rules_are_one_object  FAIL -> ok
+  test_risks_store.TestTheReadersAreOneFunction.test_the_columns_are_one_list                          FAIL -> ok
+  test_risks_store.TestTheReadersAreOneFunction.test_the_register_header_predicate_is_one_object        FAIL -> ok
+```
+
+The **set** is identical. The three outcome differences are exactly the
+pre-existing `assertIs` module-identity failures the brief names — `parsers`
+imports twice under whole-suite `discover`, so the two runners genuinely
+disagree about three tests, and they are these three, named. That disagreement
+predates this row and this row does not touch it. It is now a measured quantity
+rather than a warning.
+
+## 6. Coverage proofs — mutation, not argument
+
+Harness: `scratchpad/m230/mut230.py`, a name nothing else in this worktree uses.
+It refuses to start on a dirty tree (it printed `tree clean at 78aa67e` for the
+first five and `tree clean at 317042e` for M6-M8), asserts
+the target is **green before** mutating — a red there proves nothing and is
+refused — anchors each edit by line number, asserts the old text is present and
+unique before replacing it, clears every `__pycache__`, crosses the whole-second
+mtime boundary either side of the write, and restores by comparing `md5` against
+the hash taken before the edit. It reported `tree after harness: clean`.
+
+The three modules whose scheduling this row moves most are the three longest —
+they now start first — so the coverage proofs are drawn from those three, plus
+two against the runner's own new guards, plus three more (M6-M8) added after a
+V4 round showed one of those guards was not wired in.
+
+| # | mutation (an exact revert of the fix) | named test that went red |
+|---|---|---|
+| M1 | `bin/perry-lint:2386` — `_board_line_of` matches the id in **any** cell again instead of the first | `test_store_is_canonical.AFindingNamesItsOwnRow.test_a_closed_row_named_in_depends_on_is_not_a_board_row` → **FAILED (failures=1)** |
+| M2 | `bin/perry-lint:2680` — store-drift stops comparing the `title` field | `test_store_drift.TestAnEditedFileIsReported.test_the_hand_edit_yields_the_finding` → **FAILED (failures=1)** |
+| M3 | `viewer/tables.py:142` — `render_row` stops escaping the delimiter | `test_task_writer.TestTheDelimiterIsACharacterPeopleWrite.test_the_cell_survives_the_whole_write_path` → **FAILED (failures=1)** |
+| M4 | `tests/parallel:170` — `parse_ids` goes back to requiring the verdict on the id's own line | `test_parallel_runner.TestTheIdParserSeesEveryOutcome.test_a_test_that_wrote_to_stderr_is_still_counted` → **FAILED (failures=1)** |
+| M5 | `tests/parallel:134` — `schedule()` **selects** instead of only reordering, dropping one module | `test_parallel_runner.TestTheHintReordersAndNeverSelects.test_a_hint_covering_everything_keeps_every_module` → **FAILED (failures=1)** |
+
+`5 mutation(s), 0 did not behave as required.` Every target was confirmed green
+first; every file was restored to its original md5.
+
+M4 and M5 are the ones that matter for *this* row: M5 is the property the whole
+design rests on — a hint may reorder the work, never select it — and M4 is the
+correction in § 4.2 proving it is real and not a comment.
+
+**And the guard I shipped survived its own deletion, which a V4 round found and
+I had argued was unavoidable.** Changing `if short:` to `if False:` in `main()`
+left the entire suite green: `unaccounted()` had three unit tests and its USE
+had none. This file previously said a unit test "cannot give" that coverage.
+**That was wrong.** It is a `run_module` monkeypatch away, the reviewer said so,
+and the test now exists — `main()` is driven directly with a stub so no test
+actually runs:
+
+| # | mutation | named test that went red |
+|---|---|---|
+| M6 | `tests/parallel:301` — `if short:` → `if False:`, the reviewer's own mutation | `test_parallel_runner.TestTheRefusalIsWiredIntoMainAndNotJustDefined.test_a_short_count_writes_no_file_and_exits_nonzero` → **FAILED** |
+| M7 | `tests/parallel:319` — `if args.ids and short:` → `if False:` (refuses, but stops failing) | same test → **FAILED** |
+| M8 | `tests/parallel:301` — `if short:` → `if True:`, the guard "fixed" into refusing everything | `...test_a_count_that_adds_up_writes_the_file_and_exits_zero` → **FAILED** |
+
+Three, not one, because the refusal is two separate lines that can be deleted
+independently — writing no file, and exiting non-zero — and because a guard that
+refuses everything passes a one-directional test while being just as useless.
+`3 mutation(s), 0 did not behave as required`, tree restored to md5
+`307cdc1f877b422f9cebada39dcb64fb`.
+
+I record the original error rather than quietly deleting it: **I asserted a
+limit I had not tried to reach.** The claim that `main()` was untestable was
+load-bearing for shipping an uncovered guard, and it took someone else deleting
+the guard to find out it was false. This project's rule is that a guard which
+survives its own deletion is not a guard; mine did, for two commits.
+
+**Plus one end-to-end proof of the refusal**, which the unit tests do not cover
+because they stub out the parser entirely. With `parse_ids` truncated by one id
+in `run_module`, against the committed state:
+
+```
+✗ test_one_header_rule.py: unittest ran 12 tests and the id parser accounted for 11
+  — `--ids` would understate the set, which is the one thing it may not do.
+✗ no --ids file written
+rc=1     ids file exists? NO
+```
+
+and `tests/parallel` restored to md5 `307cdc1f877b422f9cebada39dcb64fb`, which
+is the file as committed at `642e2ca` and unchanged since.
+
+A V4 round pointed out that an earlier draft cited md5
+`430637240808773774420e83ca1b593d` here, which matches **no committed version of
+the file**. The benign reading was the right one: it was an intermediate working
+state — after the `unaccounted()` extraction, before the docstring rewrite — so
+the proof was real but the hash named a tree nobody could check it against.
+Rather than explain the old hash, the proof was **re-run against the committed
+state**, and the block above is that run.
+
+One thing this harness caught on me, worth recording because it is the whole
+argument for the discipline: my first attempt at that end-to-end proof used an
+anchor string that my own refactor had changed minutes earlier. The `assert`
+fired, no mutation was applied, and the run came back **green** — which without
+the assert I would have read as "the guard does not fire", or worse, as
+"everything is fine". A mutation that did not happen looks exactly like a
+mutation that was tolerated.
+
+## 7. Effect on flakiness — and what the spec's target does not survive
+
+**Set stability: 12 runs, 12 identical id sets of 2904.** The spec asks for five;
+this is twelve, spanning both schedules.
+
+**Outcome stability**, every test that was not `ok` in at least one of the twelve:
+
+| test | non-ok runs | alphabetical arm | longest-first arm |
+|---|---|---|---|
+| `test_diagnose` × 2 (see § 2) | 12/12 | 5/5 | 7/7 |
+| `test_kr_progress_provenance` × 1 | 12/12 | 5/5 | 7/7 |
+| `test_contract_key_parity` witness × 2 | 11/12 | 4/5 | 7/7 |
+| `test_rung_vocabulary...test_the_schema_lookup_is_the_guard_not_the_regex` | 12/12 `skipped` | 5/5 | 7/7 |
+| **`test_host_support.TestOpenCodeDispatchLimit.test_concurrent_mixed_registers_do_not_exceed_global_cap`** | **1/12** | 0/5 | **1/7** |
+
+The known flake fired **once in those twelve runs**, in the longest-first arm.
+**It then fired a second time**, in the quiet-machine run of § 8b — so the
+standing count across every full run I captured ids for is **2 of 10
+longest-first against 0 of 5 alphabetical**.
+
+I am still **not** claiming an effect. Two in ten against zero in five is not a
+difference either, and reporting the stale 1-of-7 because it read better would
+be the exact failure this row exists to catch. What can be said is that it did
+not become common — the brief records it flaking three times under the old
+arrangement — and that it was not retried away, hidden, or excluded here.
+
+**And the second occurrence cuts against my own explanation.** The mechanism I
+volunteered below says longest-first concentrates contention at the start of the
+run; the quiet-machine run had a load average of 5.76 and flaked anyway. That is
+one data point, not a refutation, but it is evidence against the story I told,
+and it belongs here rather than in a drawer. The filed measurement TASK-244's
+sibling needs is a repeated single-module run, not more full-suite runs.
+
+**There is a mechanism that could plausibly make it worse, and it is worth
+writing down for whoever measures next:** longest-first deliberately starts the
+eight heaviest modules simultaneously, so peak contention now coincides with the
+start of the run rather than being spread through it, and
+`TestOpenCodeDispatchLimit` is a *concurrency* test. That is a reason to keep
+watching it, not a finding. It is also the second reason the worker count was
+left at 8.
+
+**The spec's "under two minutes" target: not met as a guarantee, it cannot be
+by this approach, and the spec contradicts itself about it** — it forbids
+sharding below the file while asking for a number only sharding below the file
+can reach. A V4 round ruled that non-blocking and filed the real work as
+**TASK-244**. The floor is a single module. `test_task_writer.py` alone
+took 105.4s, 120.1s, 133.1s, 140.0s and 149.2s in the runs above, and the whole
+run finishes when it does. Three of the four `--times` runs came in under 150s
+and one came in at 120.1s, so the target is reachable on a machine with capacity
+and unreachable on a busy one — and no number of workers moves it, which is the
+`floor` column in § 3. Moving it means sharding *below* the file, which changes
+the isolation boundary the fixtures assume and which the spec explicitly scopes
+out ("shard by file, never by test method"). **I did not do it**, and I think
+splitting `test_task_writer.py` — 4504 lines, 42 classes, 281 tests, every one
+of them spawning `python3` subprocesses — is the next row, not a footnote to
+this one.
+
+Against the row's actual trigger, though: the two dispatches that died on 2026-08-28
+were killed by a **600-second** watchdog. Serial is 589.6s and touches it;
+the parallel run's worst of twelve was 285s and its median 149.7s.
+
+## 8. Full gate on the committed state
+
+`bash tests/run` on `642e2ca`, 02:45-02:50, foreign load 25.7 rising to 59.1:
+**266.7s wall**, `99 modules · 2907 tests`, `user 338.6s sys 153.9s`.
+
+Red on **exactly the five pre-existing failures enumerated in § 2, in three
+modules, and on nothing else**:
+
+```
+✗ test_contract_key_parity.py   test_without_the_witness_the_four_are_unobservable
+                                test_the_same_mutation_is_silent_without_the_witness
+✗ test_diagnose.py              test_the_queue_register_reconciles_with_the_queue_on_this_repository
+                                test_perry_itself_passes_its_own_id_checks
+✗ test_kr_progress_provenance.py test_no_current_in_the_payload_claims_to_be_a_measurement
+```
+
+Step 1 (`perry-lint --templates`) and step 4 (both sample projects, English and
+Chinese) print `✓ clean`. Step 3's summary line is suppressed by `tests/run`'s
+own `[ "$fail" = 0 ]` guard once step 2 has failed, so it prints nothing rather
+than failing — no `✗ ... does not parse` or `--help failed` line appears, which
+is what that step emits when it is unhappy.
+
+That 266.7s is also the twelve-run spread doing its thing: the same gate, on the
+same commit, at a load average that hit 59. Log: `scratchpad/m230/final-run.log`.
+
+### 8b. And then the machine went quiet
+
+Re-running the gate on `c678cf0` at 03:15, after the foreign load finally
+dropped — **the first genuinely uncontended measurement of the night**:
+
+| | |
+|---|---|
+| `bash tests/run` | **108.9s** wall, `99 modules · 2909 tests`, `user 341.1s sys 157.0s` |
+| load average | **5.76** before, 24.0 after — and the "after" figure is my own eight workers |
+| red | the same five tests in the same three modules as § 2, and nothing else |
+
+**108.9 seconds — under the spec's two-minute target.** And a follow-up
+`--times` run on the same commit makes the shape of it unmissable: the run took
+**126.3s and `test_task_writer.py` took 126.28s**. The suite finished 0.02s
+after its longest module did.
+
+That is the same thing the reviewer's own run showed (246.74s of a 246.8s run)
+and the same thing § 3's `floor` column predicts. It is the strongest single
+statement of what this row did and did not achieve: **the schedule is optimal,
+and optimal is one module long.** The target is reachable on a quiet machine and
+unreachable on a busy one, and no scheduling change can alter that — only
+TASK-244 can.
+
+Note the CPU: 341.1s user + 157.0s sys, against 338.6s + 153.9s for the 266.7s
+run. **Identical work, less than half the wall.** The night's entire timing
+spread was the machine.
+
+## 8a. What the V4 round established independently
+
+Recorded because it is stronger than my own evidence in one place and because it
+settles four things I had left open.
+
+**The central safety claim was re-verified without using my tooling at all.**
+The reviewer enumerated test ids with unittest's **loader** — never running a
+test, never calling `parse_ids` — for whole-suite `discover` and for the
+per-module partition the runner actually executes, in separate processes:
+**2907 against 2907, zero on either side.** That loader-derived reference set
+then matched, id for id, its own independent re-implementation of my parser over
+my raw `serial.err` (2904), all twelve of my `--ids` files (2904 each, and all
+twelve pairwise identical), and its own fresh `tests/parallel --ids` run (2907).
+
+**My § 4.2 audit reproduced on a different corpus**: the old parser returned
+**2890 against unittest's own `Ran 2904`**, missing across the same seven modules
+with the same distribution. Different tree, different run, same fourteen-ish
+shortfall — the defect was structural, not an artefact of the run I found it in.
+
+**The mutation sweep was extended to thirteen**, covering every production
+surface my new tests touch. All 25 tests die under at least one, and the only
+survivor was the `main()` refusal — now M6/M7/M8 above, and no longer a
+survivor. I cite that rather than re-running it.
+
+Four things ruled settled, which I had flagged as open:
+
+- **All four declared limits are non-blocking.** The two-minute target is
+  structurally unreachable **and the spec contradicts itself**: it forbids
+  sharding below the file while asking for a number only sharding below the file
+  can reach. Filed as **TASK-244**. The reviewer's own run makes the point
+  better than my table does — it ended **0.1 seconds after `test_task_writer.py`
+  did**, 246.74s of a 246.8s run. The suite is one module wearing 98 others.
+- **Declining to claim a flakiness effect on 1-of-7 against 0-of-5 was correct.**
+  The adverse mechanism in § 7 needs a filed measurement, not a gate.
+- **The load-independent evidence survives the noisy machine.** Every cell of
+  § 3's table was re-derived independently and the conclusion stands; only the
+  validation COUNT was wrong, and it is fixed above.
+- **The `git checkout --` does not matter**, and reporting it was right: my own
+  worktree, my own uncommitted diagnostic, on a file committed minutes earlier —
+  the constraint's stated harm does not apply. The note stays in § 9 anyway.
+
+## 9. What I did not do, or could not verify
+
+- **I did not get a quiet machine.** Every number here was taken with a foreign
+  load average of 17-65 except one dip to 5.6. The § 3 simulation is my answer
+  to that, and it is a good one, but it is a model — validated to 0.1s four
+  times, and still a model. A re-measurement on an idle box would be worth
+  someone's ten minutes.
+- **I did not split `test_task_writer.py`**, so the two-minute target is not
+  guaranteed. § 7.
+- **I did not refresh `tests/durations.json`.** Its values are 3-4x inflated;
+  they still yield the optimal order, and re-recording under tonight's load
+  would not have made it more honest.
+- **I did not raise the worker count.** The floor column says it buys zero
+  seconds, and the flake mechanism in § 7 says it costs something.
+- **I did not investigate the four baseline failures.** They are pre-existing,
+  present in every run of both arms, and three of them are already filed. The
+  `test_contract_key_parity` pair flipping at ~01:55 is new information about a
+  known row and is reported here rather than chased.
+- **I cannot claim the flake rate improved or worsened.** § 7 — the sample is
+  too small and I would rather say so.
+- **The `--ids` accounting guard does not run without `--ids`.** Deliberate, and
+  the consequence is stated in § 4.2 rather than left for someone to find.
+- **I did not re-run the reviewer's thirteen-mutation sweep**, on its
+  instruction; § 8a cites it instead. My own sweep is the eight in § 6.
+- **I did not merge, and `main` keeps moving** — 67 commits ahead as I write
+  this. § 1.
+- **One process note, ruled harmless and kept anyway:** early on I used
+  `git checkout -- tests/parallel` to
+  drop a throwaway diagnostic edit of my own, in my own worktree, on a file
+  committed minutes earlier. It was safe and it recovered nothing that was not
+  mine, but `review-constraints.md` says never, and recording it is cheaper than
+  hoping nobody diffs the transcript. Everything after it was restored by
+  explicit `cp`/md5 instead.

+# TASK-230 — V4 review
+
+**PASS.**
+
+Reviewed `e685c6b`, tip of `coding/task-230-suite-cost`, in the detached worktree
+`scratchpad/review-230`. Both that worktree and the author's `scratchpad/wt-230`
+were clean at `e685c6b` before and after this round. Every mutation in this
+review was applied to a `git archive e685c6b` copy under `scratchpad/rv230/mut`,
+never to a reviewed tree. The one thing I ran inside the review worktree was the
+suite itself (`python3 tests/parallel --ids … --times`, no `--record`), which
+writes nothing into the repository; `git status --porcelain` is empty after it.
+
+---
+
+## 1. The constraint this review exists to enforce: did anything stop being tested?
+
+**No. Verified independently, by a means the author did not use, three ways.**
+
+The author's argument runs entirely through `parse_ids` — its own stderr parser
+— so I did not use it. I used `unittest`'s **loader**, which never runs a test
+and never touches the runner's code, to enumerate what whole-suite `discover`
+*collects*, and compared that against the per-module partition `tests/parallel`
+actually executes.
+
+```
+$ cd scratchpad/review-230
+$ python3 -c "... unittest.defaultTestLoader.discover('tests', top_level_dir='tests') ..."
+collected at 78aa67e: 2904          # placeholders: []
+collected at e685c6b: 2907          # placeholders: []
+
+$ ls tests/test_*.py | xargs -n1 basename \
+    | xargs -P 8 -I{} python3 rv230/one.py {} > permodule.txt   # one process per module
+2907
+```
+
+| comparison | result |
+|---|---|
+| whole-suite loader collection vs union of per-module loader collections (`e685c6b`) | 2907 vs 2907, **only-whole 0, only-per-module 0** |
+| loader collection @`78aa67e` vs **my own re-implementation** of the id parser run over the author's raw `serial.err` | 2904 vs 2904, **0 / 0** |
+| loader collection @`78aa67e` vs each of the author's **12** `--ids` files | 12/12 exactly 2904, **0 / 0** each |
+| **my own fresh `tests/parallel --ids` run @`e685c6b`** vs loader collection @`e685c6b` | 2907 vs 2907, **0 / 0** |
+| all 12 author id files pairwise | `all 12 id sets identical: True, size 2904` |
+
+So the claim "2904 = 2904, zero on either side, 12 identical sets" is true, and it
+is true against a reference that does not pass through the author's code at all.
+`schedule()` is `sorted(mods, key=…)` over the glob's own result — a permutation
+by construction — and `mods` is computed before and independently of
+`durations.json`. Sharding by module changes the order and nothing else.
+
+**Outcome comparison, my run vs the author's serial log** (my parser, not theirs):
+
+```
+differing outcomes on shared ids:
+  test_risks_store.TestTheReadersAreOneFunction.test_the_bullet_and_placeholder_rules_are_one_object FAIL -> ok
+  test_risks_store.TestTheReadersAreOneFunction.test_the_columns_are_one_list                        FAIL -> ok
+  test_risks_store.TestTheReadersAreOneFunction.test_the_register_header_predicate_is_one_object     FAIL -> ok
+```
+
+Exactly the three pre-existing `assertIs` module-identity failures § 5 names, by
+name, and nothing else. § 5 is accurate.
+
+**Total CPU, independently** (from the author's `/usr/bin/time -p` files, and my
+own run): alphabetical `user+sys` 501.3s / 500.5s, longest-first 475.8s / 482.6s,
+mine 491.1s. Meanwhile the *sum of per-module wall times* swung 766s → 1236s
+across the same four runs. Constant CPU under a 1.6x swing in summed wall is the
+signature of contention, not of lost work — a genuinely separate argument from
+the id-set check, and it holds.
+
+---
+
+## 2. The audit of the inherited commit — all three claims reproduced
+
+### Claim 1: the inherited `--ids` set silently dropped 14 tests — **CONFIRMED**
+
+Reproduced on a **different corpus** than the author used. The author measured on
+per-module parallel output; I ran both parser versions over the author's raw
+`serial.err` (the serial `discover -v` log, 553 KB):
+
+```
+old parser ids: 2890   unique: 2890
+new parser ids: 2904   unique: 2904      # unittest's own line: "Ran 2904 tests"
+in new but not old: 14
+    test_events_feed 2
+    test_live_state_expectations 3
+    test_migrate 3
+    test_one_header_rule 1
+    test_one_startable_rule 3
+    test_shipped_vocabulary 1
+    test_stranded_rows 1
+```
+
+Fourteen, across exactly the seven named modules, with the same per-module
+distribution. The mechanism is exactly as described: `unittest` prints ` ... `
+when the test *starts*, so a `DeprecationWarning` written to stderr pushes the
+verdict onto its own line, and the old `_OUTCOME.search` — which requires
+` ... <verdict>$` — matched nothing. The old count on the diag run was 2885 of
+2899; on the serial log it is 2890 of 2904. Both are 14 short. Self-consistent,
+and `ids-diag.tsv` / `ids-longest-1.tsv` are on disk at 2885 lines while every
+post-fix file is at 2904. This was a real defect and the audit is right.
+
+### Claim 2: the refusal fires — **CONFIRMED, and I could not defeat it in the way that matters**
+
+End-to-end, in the copy, with `run_module` truncated by one id:
+
+```
+$ python3 tests/parallel test_one_header_rule --ids …/refuse.tsv   # control
+1 modules · 12 tests · 1.0s · 8 workers
+✓ all green                      control rc=0, file written (1255 bytes)
+
+# mutate: "ids": parse_ids(proc.stderr)  ->  parse_ids(proc.stderr)[:-1]
+✗ test_one_header_rule.py: unittest ran 12 tests and the id parser accounted for 11
+  — `--ids` would understate the set, which is the one thing it may not do.
+✗ no --ids file written
+mutant rc=1     ids file exists? NO
+restored md5 307cdc1f877b422f9cebada39dcb64fb (MD5 MATCH)
+```
+
+Attempts to defeat it (`parse_ids` evaluated directly, no writes):
+
+| shape | result | guard |
+|---|---|---|
+| verdict glued onto un-newlined output (`… ... some output ok`) | 0 ids vs `Ran 1` | **fires** — the author named this shape |
+| test writes `Ran 5 tests` to stderr | inflates `ran` | **fires** (fail-safe direction) |
+| a *failing* test writes `ok` to stderr | records `('mod.C.test_x','ok')`, count 1 = `Ran 1` | **silent** — outcome column lies |
+| a test writes a line shaped `word (dotted.name)` | records `('a.b','FAIL')` — real id lost, fake id gained, count still 1 | **silent** — set corrupted |
+
+Both silent shapes are residual, not blocking, and I say why in § 6. Neither can
+turn a red module green: the runner's verdict comes from the subprocess **exit
+code** (`r["rc"] != 0`), which never passes through `parse_ids`. And my loader
+cross-check proves neither shape occurs on today's suite — the parsed set is
+byte-for-byte the collected set.
+
+### Claim 3: the inherited docstring's numbers were unreproducible — **CONFIRMED**
+
+`tests/durations.json`, committed in the same change as the docstring claiming
+322/282/234s, records `test_task_writer.py 567.25`, `test_store_drift.py 548.85`,
+`test_store_is_canonical.py 463.53`. A 2x disagreement between two artifacts of
+one commit. The replacement numbers *are* reproducible in the way the originals
+were not: every run has a label, a timestamp, a load average before and after,
+a `/usr/bin/time` file, and an id file on disk (`m230/times.txt`,
+`m230/campaign.txt`, `m230/cpu-*.txt`, `m230/ids-*.tsv`). I recomputed from
+those raw files and got the published numbers. That is the difference.
+
+---
+
+## 3. The A/B: I re-derived the simulation from scratch and it is arithmetically right — but the "0.1s, four of four" is oversold
+
+I wrote my own greedy list-scheduler over each run's own `--times` output and my
+own `schedule()`/`sorted()` orderings. Every cell of § 3 reproduces:
+
+```
+run           n      sum     max   floor  simAlpha  simHint  simPerf
+t-alpha-1    99    766.4   120.1   120.1     179.7    120.1    120.1
+t-hint-1     99   1052.8   140.0   140.0     222.9    140.0    140.0
+t-alpha-2    99   1235.9   149.2   154.5     241.1    155.4    154.5
+t-hint-2     99    978.0   133.1   133.1     210.4    133.1    133.1
+```
+
+Identical to the result's table, including the 0.9s loss to perfect knowledge in
+`t-alpha-2`. The measured walls were 179.76 / 140.08 / 241.13 / 133.09.
+
+**But two of the four "predictions" are arithmetically forced, not predictions.**
+In both longest-first runs the makespan equals the *longest single module's own
+measured duration* (140.0 and 133.1) because that module started first and the
+run cannot end before it. Simulating it back gives the same number by identity.
+Only the two alphabetical runs are non-trivial — there `max` is 120.1 and 149.2
+while the simulated and measured makespans are 179.7 and 241.1, so the packing
+model really is doing work and really is exact.
+
+So the correct statement is: **the model is validated by two of the four, not
+four of four, and that is still enough.** The result's "The model is exact …
+four times out of four. That is the reason to believe the other column" (and the
+same sentence in `tests/parallel`'s docstring, "**The model is exact**") is an
+overclaim about the strength of the evidence, not about the conclusion. The
+conclusion survives on the two real validations plus two independent supports:
+the measured medians (188.4s alphabetical vs 149.7s longest-first) and the
+structural floor argument. **Not blocking; the sentence should be corrected.**
+
+A second, unstated modelling assumption: the counterfactual column assumes
+per-module durations are invariant to the schedule. They are not — the summed
+module time varied 766s to 1236s across the four runs. The bias runs *against*
+longest-first (its heavy modules are measured while contending with each other),
+so the 33–37% figure is conservative rather than flattering. Worth a sentence in
+the result; not a defect.
+
+---
+
+## 4. Mutation: all five reproduced, and I extended the sweep to every new test
+
+I re-ran all five of the author's mutations at `e685c6b` (they were originally
+run at `78aa67e`), in the archive copy, restoring by md5 each time.
+
+| # | mutation | my result |
+|---|---|---|
+| M1 | `bin/perry-lint:2386` `_board_line_of` matches any cell | `test_store_is_canonical…test_a_closed_row_named_in_depends_on_is_not_a_board_row` **FAILED (failures=1)** |
+| M2 | `bin/perry-lint:2684` drop `title` from store-drift comparison | named test **FAILED**; whole module **FAILED (failures=4)** |
+| M3 | `viewer/tables.py:142` `render_row` stops escaping `\|` | `test_task_writer…test_the_cell_survives_the_whole_write_path` **FAILED (failures=1)** |
+| M4 | `parse_ids` reverts to the inherited shape | **FAILED (failures=3)** incl. the named test |
+| M5 | `schedule()` selects instead of reordering | **FAILED (failures=9)** incl. the named test |
+
+M2's anchor in the result (`bin/perry-lint:2680`) points at a five-line block
+whose last line appears **four** times in the file (2684, 2833, 2972, 3095 — the
+task, risk, intake and ask store-drift checks). The author's harness anchors on
+the full five-line block, which is unique, so the mutation landed correctly. My
+first attempt used only the last line, the uniqueness assert fired, and the test
+came back green — an unplanned live demonstration of exactly the harness property
+in § 6.
+
+### Does any guard survive its own deletion?
+
+I mutated **every** production surface the new tests cover, not only the five.
+All 25 tests in `tests/test_parallel_runner.py` die under at least one mutation;
+none is decorative or vacuous.
+
+```
+G1 load_durations stops coercing/filtering  -> 2 red
+G5 load_durations stops swallowing          -> 4 red (errors)
+G10 load_durations returns {} always        -> 1 red (test_a_good_file_reads_as_the_hint)
+G6 drop the same-line outcome branch        -> 6 red
+G7 drop the "no open test" guard            -> 1 red
+G2 unaccounted reports only undercounts     -> 1 red
+G8 unaccounted never reports                -> 2 red
+G9 unaccounted always reports               -> 2 red
+M4 / M5 as above                            -> 3 / 9 red
+```
+
+**One guard does survive its own deletion, and it is this row's own:**
+
+```
+G3: in main(),  if short: print("✗ no --ids file written")  ->  if False: …
+$ python3 -m unittest discover -s tests -p test_parallel_runner.py
+Ran 25 tests in 1.010s
+OK
+```
+
+Delete the refusal from `main()` and the suite stays green. `unaccounted()` is
+unit-tested; **its use — the actual refusal to write and the `return 1` — is
+not.** The result's framing, "*Plus one end-to-end proof of the new refusal,
+which a unit test cannot give*", is wrong: a unit test can give it trivially by
+monkeypatching `P.run_module` and calling `P.main()` with a patched `sys.argv`,
+in the same file that already shells out to a subprocess for
+`test_every_test_in_the_live_suites_noisiest_module_is_accounted_for`.
+
+Why this does not block: `main()` has **never** had coverage in this file — the
+pre-existing zero-test guard survives its own deletion identically
+(`empty = []` → `Ran 25 … OK`). The row added a third guard to an already
+untested function rather than lowering an existing bar; the refusal demonstrably
+fires today (§ 2, reproduced by me); and the property it protects is not the
+gate — verdicts come from exit codes. **File it as a follow-up row**: cover
+`main()`'s three guards (zero-test, module-red, `--ids` refusal), and delete the
+"a unit test cannot give it" sentence.
+
+---
+
+## 5. Baselines — pre-existing, and I confirmed it against a tree that predates the row
+
+`git archive` copies at the fork point `ee0b36a` and at `642e2ca`, running the
+named tests directly:
+
+```
+===== ee0b36a (fork point, 66 commits back, predates every commit in this row) =====
+  test_without_the_witness_the_four_are_unobservable            FAILED (failures=1)
+  test_perry_itself_passes_its_own_id_checks                    FAILED (failures=1)
+  test_the_queue_register_reconciles_with_the_queue_on_this_repository  FAILED (failures=1)
+  test_no_current_in_the_payload_claims_to_be_a_measurement     FAILED (failures=1)
+===== 642e2ca ===== identical
+```
+
+**None of the five baseline reds is caused by this row** — they reproduce on a
+tree that does not contain it. That is a stronger statement than the author's and
+it agrees with theirs.
+
+The author's corroborating observation reproduces exactly. Recomputing § 7's
+outcome table from the 12 id files:
+
+```
+ 12/12  alpha=5/5 hint=7/7  test_diagnose … test_the_queue_register_reconciles…
+ 12/12  alpha=5/5 hint=7/7  test_diagnose … test_perry_itself_passes_its_own_id_checks
+ 12/12  alpha=5/5 hint=7/7  test_kr_progress_provenance … test_no_current_in_the_payload…
+ 12/12  alpha=5/5 hint=7/7  test_rung_vocabulary … (skipped)
+ 11/12  alpha=4/5 hint=7/7  test_contract_key_parity … test_without_the_witness_the_four…
+ 11/12  alpha=4/5 hint=7/7  test_contract_key_parity … test_the_same_mutation_is_silent…
+  1/12  alpha=0/5 hint=1/7  test_host_support … test_concurrent_mixed_registers_do_not_exceed_global_cap
+```
+
+The `test_contract_key_parity` pair is red in **4 of 5 alphabetical runs** — it
+flipped between two runs of the *same* arm, which rules the schedule out, and it
+is red on the fork-point tree too. The author's reasoning is sound and the data
+supports it.
+
+My own run reproduces the whole picture: `99 modules · 2907 tests · 246.8s ·
+8 workers`, red on exactly `test_contract_key_parity` (2), `test_diagnose` (2),
+`test_kr_progress_provenance` (1) — five tests, three modules, nothing else.
+
+---
+
+## 6. Ruling on each declared limit
+
+### Limit 1 — "under two minutes" is not achievable by this approach. **Does not block. The author is right, and the spec contradicts itself.**
+
+The floor argument is `makespan ≥ max(longest module)` and no worker count moves
+it. My own run demonstrates it about as cleanly as it can be demonstrated:
+
+```
+  seconds  tests  module
+   246.74    281  test_task_writer.py        <- the longest module
+…
+99 modules · 2907 tests · 246.8s · 8 workers  <- the whole run
+```
+
+The run ended **0.1s** after its longest module did. Reaching 120s requires
+splitting `test_task_writer.py`, and the spec itself says "**shard by file, never
+by test method**" in its own Out-of-scope/hazards section. The target and the
+constraint cannot both be honoured; the author identified the contradiction,
+stated it, and declined to resolve it by violating the constraint. That is the
+right call.
+
+The number that actually matters is the one the row was opened on: a **600s**
+watchdog. Serial is 589.6s and touches it. The worst of twelve parallel runs was
+285.0s, the median 149.7s, and mine 246.8s under load 25→46. The trigger is
+addressed with margin. Ship it and file the `test_task_writer.py` split as its
+own row, as the author proposes.
+
+### Limit 2 — declining to claim a flakiness effect. **Correct, and the mechanism does not need measuring before this ships.**
+
+1 of 7 against 0 of 5 is not a difference by any test one could apply, and
+reporting it as "0% → 14%" would have been the dishonest option. Declining is the
+right call and the author volunteering the *adverse* mechanism — longest-first
+deliberately starts the eight heaviest modules at once, so peak contention now
+coincides with a concurrency test — is the behaviour this project wants.
+
+I rule that it does not block, for three reasons: the flake is pre-existing and
+already filed; the run is now 2–4x shorter, so the exposure window is smaller,
+not larger; and the counterfactual is not "no flakes", it is the serial suite
+that is currently killing dispatches. It is 0/1 in my run.
+
+It should be **filed as a follow-up with a concrete design** — N ≥ 30 runs of
+`test_host_support` alone under both schedules — rather than left as a paragraph.
+An adverse mechanism named and then not measured is the kind of thing that gets
+rediscovered as a mystery in three weeks.
+
+### Limit 3 — the machine was never quiet. **The evidence survives its conditions.**
+
+Load was 17–65 for the author and 20–46 for me; the identical command took 133.1s
+and 285.0s for them and 246.8s for me. Wall-clock here is not a measurement and
+the author says so first, in § 1, before quoting any number.
+
+What survives is everything load-independent, and that is the load-bearing part:
+the id-set equality (a set, not a clock — and I re-derived it from a static
+loader, which has no timing component at all); the CPU totals; and the floor
+`makespan ≥ max module`, which I reproduced to 0.1s on my own differently-loaded
+run. The wall-time saving is the weakest claim and rests on medians plus a model
+validated twice; § 3 above states what that is worth. The author's own framing —
+"it is a model … a re-measurement on an idle box would be worth someone's ten
+minutes" — is the right one.
+
+### Limit 4 — 65 commits behind `main`. **Verified as far as it can be without merging; the expectation is well-founded.**
+
+```
+$ git merge-base HEAD main                                 -> ee0b36a
+$ git rev-list --count ee0b36a..main                       -> 66      (author said 65; main moved by one since)
+$ git log ee0b36a..main -- tests/parallel tests/run \
+      tests/test_parallel_runner.py tests/durations.json   -> (empty)
+$ git ls-tree -r --name-only main -- tests | grep -c 'test_.*\.py$'  -> 100
+```
+
+`main` has touched none of the four files. "Expected clean — expected, not
+verified" is the honest phrasing and it is accurate. The one behaviour that
+matters after the merge is what happens to `main`'s 100th module, which has no
+`durations.json` entry: `schedule()` keys it `-float("inf")`, so it sorts
+**first**, the safe direction. I read that and it is true. The totals in the
+result describe this branch's 99 modules and will shift on merge; the result says
+so. **The merge must still be run and the suite re-run on the merged tree** —
+that is a merge-time obligation, not a defect here.
+
+### The `git checkout --` note. **It does not matter, and reporting it was right.**
+
+One `git checkout -- tests/parallel`, in the author's own dedicated worktree, on
+its own uncommitted diagnostic edit, on a file it had committed minutes earlier.
+`review-constraints.md`'s prohibition sits under "**You are a reader** / The
+repository is live", and the harm it names is destroying work that is not yours
+and is not recoverable. In a single-purpose worktree containing only the author's
+own in-flight change, on a file whose committed state was minutes old, neither
+condition applies.
+
+I can corroborate the outcome, not the transcript: `wt-230` is clean at
+`e685c6b`, its `tests/parallel` md5 matches the committed blob exactly
+(`307cdc1f…`), and every commit's content is intact. I cannot audit what the
+discarded diff contained; that is in `not-checked` below. Switching to explicit
+`cp`/md5 afterwards was the right correction, and volunteering it rather than
+hoping nobody diffed the transcript is exactly the behaviour that makes the rest
+of this result document worth believing.
+
+---
+
+## 7. Findings — all non-blocking, all should be filed or fixed before merge
+
+1. **`main()`'s `--ids` refusal survives its own deletion** (§ 4, G3). Delete it
+   and the suite is green. Follow-up row; and remove the incorrect sentence "which
+   a unit test cannot give".
+2. **"The model is exact … four times out of four" is an overclaim** (§ 3). Two of
+   the four agreements are arithmetic identities. Correct the sentence in
+   `perry/evidence/2026-08/TASK-230-result.md` § 3 **and** in `tests/parallel`'s
+   docstring, which repeats it. The conclusion does not change.
+3. **An md5 citation that matches nothing.** Result § 6 says the end-to-end
+   refusal proof restored `tests/parallel` to md5
+   `430637240808773774420e83ca1b593d`. The file's md5 is `ce4fe6e0…` at
+   `23e6197`, `7e66ae40…` at `78aa67e`, `307cdc1f…` at `642e2ca` and `e685c6b`.
+   The benign reading — that the proof ran on an intermediate working state
+   carrying the new guard but not yet the rewritten docstring — is consistent
+   with everything else and with the tree being clean and correct now. But as
+   written the citation is unverifiable. Say which state it hashes, or drop it.
+4. **The headline quotes the favourable subrange.** `tests/parallel`'s docstring
+   header and `tests/run`'s comment both say "589.6s serial → 133–150s across 8
+   workers", omitting the 247.0s and 285.0s runs that appear four lines further
+   down. Mine was 246.8s. A reader of `tests/run` will form a wrong expectation.
+   Quote the median (149.7s) or the full range.
+5. **Two residual `parse_ids` shapes the accounting guard does not catch** (§ 2):
+   a test writing a bare verdict to stderr silently mislabels its own outcome; a
+   test writing a line shaped `word (dotted.name)` silently substitutes one id
+   for another with the count unchanged. Neither can flip a module's verdict
+   (that comes from the exit code) and neither occurs on today's suite (proved by
+   the loader comparison). Worth a sentence in `parse_ids`'s docstring beside the
+   shape that *is* named.
+6. **Cheap hardening, optional:** `main()` never asserts `len(order) == len(mods)`
+   at runtime. `schedule()` is a permutation by construction and is covered nine
+   ways, so this is belt-and-braces — but it is one line at the point where a
+   dropped module would otherwise be invisible.
+
+---
+
+## checked / not-checked
+
+**checked** — id-set equality via an independent `unittest` loader enumeration at
+two commits, whole-suite vs per-module, in separate processes (0/0 both ways);
+the same set against my own re-implementation of the id parser run over the
+author's raw serial log (0/0); the same set against all 12 of the author's `--ids`
+files (0/0 each) and against my own fresh `tests/parallel --ids` run (0/0);
+pairwise identity of the 12 sets; the outcome diff serial-vs-parallel (exactly
+the 3 named `test_risks_store` tests); the 14-dropped-tests audit reproduced on a
+different corpus, same 7 modules, same distribution; the `--ids` refusal proved
+end-to-end in a copy plus four attempts to defeat it; the § 3 simulation
+re-derived from scratch (every cell reproduces) and its two tautological cells
+identified; CPU totals from the raw `time -p` files and from my own run; all five
+author mutations re-run at `e685c6b`; eight further mutations covering every
+production surface the new tests touch (all 25 tests die under at least one; one
+guard survives, named above); the mutation harness source read and its
+anchor-assert, uniqueness-assert, green-before-assert, pycache-clear, mtime-tick
+and md5-restore clauses all confirmed present; the baseline reds reproduced on
+the fork point `ee0b36a`; the § 7 outcome table recomputed from the id files
+(reproduces digit for digit); the branch-distance and untouched-files claims;
+`tests/run`'s step-2 change (comment only, `--serial` escape intact) and its
+`[ "$fail" = 0 ]` suppression of step 3's summary; `durations.json` (99 entries,
+values as described); `tests/gate.py`/`GATE_OFF` is not reachable from any new
+test.
+
+**not-checked** — I did not run a serial `discover` myself (≈590s on a loaded
+box); I used the author's raw `serial.err` and parsed it with my own code
+instead, plus the static loader enumeration, which together cover the same
+question. I did not merge `main` into the branch or run the suite on a merged
+tree. I did not re-measure on a quiet machine — the box was at load 20–46
+throughout, so my 246.8s wall is one sample and not a contradiction of the
+author's median. I did not attempt to reproduce the `test_host_support` flake
+(one event in twelve is not something a single review round can move). I did not
+audit the author's transcript, so I cannot verify the content of the diff dropped
+by the `git checkout --`, only that the resulting tree and commits are intact. I
+did not investigate the five pre-existing baseline failures beyond establishing
+that they predate this row.

+## What changed
+
+**Eight code commits, plus four revisions of this file.** The last two code
+commits are round 2 and exist because the V4 review of round 1 **FAILED**. The
+code fix there is two lines; the corrections to this report are the larger part,
+and § 4 is rewritten around them.
+
+| sha | what |
+|---|---|
+| `fce8c0d` | the settings come out of the store, not the projection |
+| `ca6bb16` | `perry-config render` rebuilds the file from the store alone |
+| `1928e38` | the prose gets a home a render cannot destroy, and a guard |
+| `02dc442` | the "unreadable store" guard was guarding one branch of two |
+| `b0d8cde` | "refuses" has to mean a refusal, not a traceback |
+| `d32ec76` | "is there a `.perry/config.md`" stopped being "is this configured" — **four of six** |
+| `40eb4cc` | **round 2** — the other two, in `bin/perry-state`, after the V4 review found them, plus a guard for the reviewer's X4 |
+| `d1deefb` | **round 2** — the X4 guard's control tripped the live-state sweep and did not need to |
+
+### 1 — the readers prefer the store
+
+`viewer/parsers.py` gained `config_store_records` / `config_store_settings` /
+`declared_state_root` and the `CONFIG_STORE_*` reasons. **That file rather than
+`bin/perry-state`**: `perry-conform` cannot import a hyphenated `perry-state`
+without dragging `perry-lint` in on the way, and `resolve_state_root` runs
+before any tool has started. `parsers.py` is the bottom of the import graph and
+is the one place all three readers already reach — the move `ask_is_answered`
+made one register over. `perry_md_store` is imported lazily inside the function
+because it imports `parsers.py` at module scope and reads the schema at import
+time; a failure there returns `unreadable` rather than an ImportError.
+
+`bin/perry-state § _validated_config_records` is now a delegate. Its name,
+its constants and its return contract are unchanged, so every caller in that
+file is too, and `tests/test_config_store_readers § TestTheTwoNamesForOneReason`
+asserts the two spellings are the same three strings rather than leaving it to
+be noticed.
+
+Three readers converted:
+
+- `bin/perry-state § parse_config` — the six settings, plus `Packs`. The
+  payload gained `settings_source`, which travels with the values for the
+  reason `tracks_source` travels with the tracks.
+- `bin/perry-conform § gate_mode` — `Conformance gate`.
+- `viewer/parsers.py § resolve_state_root` — **`State root`. Not named in the
+  spec, and in anyway**, because without it the spec's own first verification
+  step is dishonest. Measured on a copy of this tree at `658e8c9` with
+  `.perry/config.md` deleted and the store holding `State root: perry`:
+
+      $ python3 bin/perry-state --root . --json
+      "warnings": ["No Perry state found — run /perry for first-time setup."]
+
+  Every path had resolved against the project root instead of `perry/`. "Every
+  setting still resolves" means nothing while the setting the other reads are
+  relative to does not.
+
+The precedence in all three: env (gate only) → store → markdown → default.
+**A usable store carrying no record for a key is an ANSWER**, not a reason to
+read the markdown: the store is derived wholesale from the preamble, so a key
+it does not carry is a line the file does not have. Falling through there would
+reintroduce the two-registers problem on the one setting that decides whether
+every other write is allowed.
+
+A stored blank comes back as the blank marker — `- Code repo path: —` and a
+record with `value: ""` are one state, and `track_from_record` has restored the
+marker since TASK-095 for the same reason. `blank_marker()` moved to `lib` so a
+renderer that has no file to copy it out of is not a second hardcoded `—`.
+
+### 2 — `perry-config render` rebuilds from the store alone
+
+`perry_md_store § scaffold_config` builds the whole document from the records:
+the title, the settings in stored order, the `## Tracks` heading and table in
+stored order. `main` no longer bails on a missing file when the command is
+`render`, and feeds the scaffold through the same `plan`/`render` path every
+other command uses.
+
+**The scaffold is checked, not trusted.** It is written independently of
+`scan_config` and `render_lines`, so passing it back through them is a real
+round trip: a column emitted in the wrong order comes back with its cells
+rewritten, and a record the scaffold cannot express lands in
+`records_not_in_the_file`. Either condition refuses at exit 2 with the first
+differing line rather than writing a file that silently says less than the
+store does. A `setting` record with no `label` refuses too — the label IS the
+line and `setting_key` is a lossy squash of it, so rebuilding one would guess
+at the user's own capitalisation. A store carrying no `track` record writes no
+`## Tracks` section, because DESIGN-003 reads an absent section as one implicit
+`main` and an empty table would state something the store does not.
+
+`OKR.md` has no scaffold and `perry-okr render` with no file still refuses,
+saying why: that document is mostly mission, principles and per-objective
+narrative, and a scaffold there would emit a KR table under headings the store
+has no record of.
+
+**One correction to the spec's measurement.** It records `perry-config render`
+with the file deleted as printing `no .perry/config.md` and **exiting 0**.
+Measured at `658e8c9` on a copy, the exit code is **2**, not 0
+(`perry_md_store § main`, `return 2`). Everything else in that sentence holds —
+it printed the message and wrote nothing.
+
+### 3 — the prose has a home
+
+`.perry/config.md` carried 29 lines (spec: 27) the store has no field for. They
+are verbatim in **`.perry/hook.md § Configuration notes`**: tier 1, owned by the
+user, read at every standup by every lane, and rendered from nothing.
+
+The general rule is **`reference/config.md § Prose in this file is layout, and
+`.perry/hook.md` is where it belongs`**, and it says the contract has two halves
+of which only one is a promise:
+
+- settings and track rows are recoverable — delete the file and
+  `perry-config render --write` brings it back;
+- prose is not — it survives a render only while a file is there to copy it out
+  of, and that guarantee ends the first time the file is deleted, or a project
+  is cloned without it.
+
+It is not stored on purpose. DESIGN-013 § 5.1 puts a schema'd fact in exactly
+one store and § 5.5 rejects moving prose into one **by name**, so a store that
+could rebuild the prose would be the design's own rejected alternative. A note
+left in `.perry/config.md` is still not an error; `perry-config verify` reports
+it as a line the store does not hold, which is true and is the point.
+
+`reference/config.md` rather than only `.perry/hook.md` for the rule, and
+`.perry/hook.md` rather than `reference/config.md` for Perry's own two notes:
+`reference/` ships with the skill and is read by every adopted project, so
+gimegime-pmo's nine screens of dispatch lessons could not go there. Per-project
+prose needs a per-project home, and every Perry project already has one.
+
+`SKILL.md:89` and `:195` were rewritten. `:89` no longer reads an absent
+`.perry/config.md` as "never configured".
+
+### 4 — six existence checks, in two rounds (`d32ec76`, `40eb4cc`)
+
+> **Round 1 said four call sites "were the rest". That sentence was wrong, it
+> was never checked, and the V4 review FAILED this row for it.** The correction
+> is the first thing in this section because it is the more important half of
+> round 2; the code fix is two lines.
+
+**"An absent markdown stops meaning 'never configured'"** is the deliverable's
+own wording, and call sites were still deciding exactly that by asking whether
+`.perry/config.md` exists. `bin/perry-goals § tracks_of` had already been asking
+the wide way since TASK-095 (`jsonl exists OR md exists`). **Six** were
+converted, in two rounds:
+
+| round | site | needs |
+|---|---|---|
+| 1 (`d32ec76`) | `bin/perry-lint § is_adopted` | — |
+| 1 | `bin/perry-lint § main`, the project-root walk | — |
+| 1 | `bin/perry-explain` | — |
+| 1 | `viewer/parsers.py § _resolve_project_root` | — |
+| **2** (`40eb4cc`) | **`bin/perry-state § build:2022`**, the `installed` gate | `--root`, and a project with no `BOARD.md` / `OKR.md` / `design/DESIGN-*.md` |
+| **2** | **`bin/perry-state § resolve_root:2607`**, its own project-root walk | cwd BELOW the project root |
+
+Line numbers above are the round-1 tip's (`632c198`), matching the V4 review;
+after `40eb4cc` the same two sites are `:2026` and `:2616`.
+
+`:2607` was a **byte-for-byte duplicate** of the walk round 1 converted in
+`bin/perry-lint § main` and `parsers § _resolve_project_root`. `bin/perry-state`
+is the file the spec names first, and it kept its own private copy of both the
+walk and the gate.
+
+#### What the two sites did, reproduced on the round-1 tip before the fix
+
+`git archive 632c198` into a scratch copy, `.perry/config.md` deleted, store
+untouched, `cwd` = `<project>/subdir`, `PERRY_PROJECT` unset, `PERRY_HOME` = the
+copy:
+
+    $ python3 ../bin/perry-lint | head -1
+    perry-lint · …/walk (state root: perry/)                    ← converted walk: finds it
+
+    $ python3 ../bin/perry-state --json
+    "project": {"root": "…/walk/subdir", "name": "subdir"}
+    "installed": false
+    "warnings": ["No Perry state found — run /perry for first-time setup."]
+
+**That warning string is the one this row quotes as the defect that justified
+converting `resolve_state_root`.** Round 1's own justification still reproduced,
+one file over. After `40eb4cc`, same command, same tree:
+`"root": "…/walk2/perry"`, `installed: true`, no warning.
+
+Second site, `--root` given so the walk is out of play — two minimal projects,
+`.perry/` and nothing else:
+
+| project | round-1 tip | after `40eb4cc` |
+|---|---|---|
+| `.perry/config.jsonl` only | `installed: false` + the first-time-setup warning | `installed: true` |
+| `.perry/config.md` only | `installed: true` | `installed: true` |
+
+A store-configured project read as never configured; the same project configured
+by the projection read as configured. That is the sentence the deliverable was
+written to remove.
+
+#### How § 4's claim got past me
+
+Not by being unexamined generally — by being **asserted at the wrong altitude
+from a search I did once and then reasoned from.** I found the four sites by
+reading callers of the pattern, converted them, and wrote "these were the rest"
+as a summary of *what I had converted*, not as a claim I had gone back and
+tested. The declared grep in the round-1 § "what I did not do" —
+`grep -rn "config\.md" bin viewer | grep 'exists()'` — returns **both missed
+sites in one command**; the reviewer ran it and it took seconds. I had cited that
+grep as a *limitation* of the value-reading sweep (gap 4) and never re-ran it
+against the *existence-check* class I was simultaneously calling complete. So the
+one command that would have falsified § 4 was named in the same document, three
+sections down, in a paragraph about a different question.
+
+The mechanical failure sits underneath that: **round 1 had no test that ran
+`bin/perry-state` for this property at all.** Every round-1 guard on `configured`
+called the predicate directly or called `perry-lint § is_adopted`. A completeness
+claim across N call sites with a guard on only some of them is a claim with no
+measurement behind it, and it should have been written as "four converted;
+the class is not swept" — which is what round 1's gap 4 said correctly about a
+neighbouring class in the same file.
+
+The general rule I am taking from it: **a sentence of the form "these were the
+rest" is a measurement, not a summary.** It needs a command in the report whose
+output is the empty set, or it needs to be written as a count.
+
+#### What the same grep returns now
+
+    $ grep -rn "config\.md" bin viewer | grep 'exists()\|is_file()'
+    bin/perry-diagnose:1373:  "config": (root / ".perry" / "config.md").is_file(),
+    bin/perry-diagnose:2501:  is_perry = (root / ".perry" / "config.md").is_file() or (
+    bin/perry-lint:637:       if (root / ".perry" / "config.md").is_file():
+    bin/perry-goals:2177:     if not (perry / "config.jsonl").exists() and not (perry / "config.md").exists():
+    viewer/parsers.py:401:    return (perry / "config.jsonl").exists() or (perry / "config.md").exists()
+
+Five lines, and **the existence-check class is NOT swept.** Stated as a count,
+not as a sweep:
+
+- `viewer/parsers.py:401` is `configured` itself — the predicate, not a caller.
+- `bin/perry-goals:2177` is already the wide form (`configured` inlined, TASK-095).
+- **`bin/perry-diagnose:1373` (`scan_tracking`) and `:2501` (`diagnose § is_perry`)
+  still ask the narrow way.** Same existence-as-configured shape, both in `bin/`,
+  both counted by `P003-O2-KR1`. The V4 reviewer named `:2501` and ruled it
+  non-blocking. **They are not converted here** — `bin/perry-diagnose` does not
+  import `parsers`, so converting them is an import change plus two guards of
+  their own, which is a row, not a line. I am declaring them rather than
+  widening § 4 into a sweep claim a second time.
+- `bin/perry-lint:637` (`track_context`) is TASK-095's class — it reads the
+  `## Tracks` table out of the markdown as truth — and the spec puts it out of
+  scope. Named here because it means the KR's count is non-zero for tracks too.
+
+`viewer/parsers.py § configured` is the one predicate. It answers about
+`.perry/` only — every caller ORs it with the state files it also accepts
+(`BOARD.md`, `OKR.md`, `phase/`), because those differ per caller and this does
+not. Its docstring now says six, says which round found which, and names
+`bin/perry-diagnose`'s two as unconverted; it said "these are the rest" as well,
+and that copy of the claim is corrected too.
+
+The guard's fixture strips `BOARD.md` and `OKR.md` on purpose: a fixture that
+kept them answers `True` whatever the predicate does, which is how a guard over
+an OR-chain passes while measuring nothing. `TestPerryStateAsksItToo` extends the
+same discipline per site — see *Mutations, round 2*.
+
+## Byte comparison — V4 step 2
+
+On a copy of the branch tree, `.perry/config.md` deleted, store untouched:
+
+    $ rm .perry/config.md
+    $ python3 bin/perry-config render --write --root .
+    perry-config: rendered …/.perry/config.md from 9 stored record(s)
+    exit=0
+    $ cmp /tmp/v4-orig.md .perry/config.md   →  IDENTICAL
+    orig md5: cf1756f695ebd119784d8af4befc3a32
+    new  md5: cf1756f695ebd119784d8af4befc3a32
+
+**Byte-identical, in full.** Before the prose moved, the same run reproduced
+lines 1–16 exactly and lost lines 17–45 — which is what the move was for.
+
+Where those lines went: `.perry/hook.md § Configuration notes`,
+`### What the two tracks carry` and `### Why the state root is not `.``,
+verbatim, under a lead-in that says where they came from and why.
+
+The rest of V4 step 1, same copy, markdown still deleted:
+
+- `perry-state --json § project.config` → `present: true`, `language: English`,
+  `chat_language: 中文`, `layout: single`, `state_root: perry`,
+  `pmo_repo: /Users/bytedance/proj/Perry`, `code_repo: —`,
+  `settings_source: store`, `tracks_source: store`, tracks `[main, intake]`,
+  `warnings: []`, and the state root used was `…/v4/perry`.
+- `perry-conform status` reported `gate: enforce`, which is Perry's own
+  (undeclared) answer. With `conformance_gate: advisory` added to the store and
+  the markdown still absent, `gate_mode` returned `advisory` against a shipped
+  default of `enforce` — the declared gate, not the default.
+- `perry-config verify` → `drift_count: 0`, `byte_identical: true`;
+  `perry-lint` → `0 error(s)`, `config store: 9 record(s), 0 row(s) drifted`.
+
+## Mutations
+
+Harness: `…/scratchpad/task233_mutation_harness.py`, `…2.py`, `…3.py` and
+`…4.py` — uniquely named, outside the repo. It **refuses to start on a dirty tree**, asserts each
+target is **GREEN and selected ≥ 1 test before mutating**, anchors by exact old
+text (refusing an ambiguous or missing anchor) and reports the line, clears
+every `__pycache__`, sleeps past the whole-second boundary CPython validates
+bytecode on, restores from the captured text and **asserts the md5 matches**.
+The runner is `python3 -m unittest discover -s tests -p <module>.py -k <sel> -v`,
+never a bare module run. Tree verified CLEAN after each batch.
+
+**Round 1: 28 mutations, 28 red.** Every one names the test it reddened.
+
+> **Correction.** Round 1's text said "27 mutations, 27 red" twice while the
+> table below carried **28** rows and the three harnesses defined 28. The V4
+> reviewer caught the arithmetic, re-derived the anchors from the harnesses and
+> ran all 28 against a clean clone with their own driver: 28 of 28 red, reddened
+> sets matching row for row. The claim was right; the count was wrong. Round 2
+> adds five more (below), for **33 total**.

+and the two copies of `test_the_store_wins_over_the_markdown` by M2 / M3.
+
+### Mutations — round 2 (`…/scratchpad/task233_mutation_harness4.py`)
+
+Same harness shape, same three refusals (dirty tree, target not green, target
+selected ≤ 0 tests), same md5-verified restore. Tree CLEAN after the batch.
+
+**5 mutations, 5 red.**
+
+| # | mutation | anchor | test that went red |
+|---|---|---|---|
+| R1 | revert `bin/perry-state § resolve_root` — the walk | `bin/perry-state:2616` | `test_the_walk_finds_a_store_only_project_from_a_subdirectory` |
+| R2 | revert `bin/perry-state § build` — the `installed` gate | `bin/perry-state:2026` | `test_the_installed_gate_counts_a_store_only_project_as_installed` |
+| R3 | X4 — `store-default` collapsed into `store` | `viewer/parsers.py:356` | `test_a_store_with_no_setting_records_says_store_default`, `test_the_distinction_reaches_the_payload` |
+| R4 | `configured` forgets the store, run against the two new sites | `viewer/parsers.py:401` | both of `TestPerryStateAsksItToo`'s site tests |
+| R5 | X4 again, selecting the payload test alone | `viewer/parsers.py:356` | `test_the_distinction_reaches_the_payload` |
+
+**Two sites, two tests, and they are provably not the same test.** The V4
+reviewer showed the sites fail under different conditions, so one test covering
+both would stay green with either one reverted. Cross-checked, each mutation run
+against the OTHER site's test:
+
+| mutation | selector | verdict |
+|---|---|---|
+| `:2607` reverted | `test_the_installed_gate_counts_a_store_only_project_as_installed` | **GREEN — independent** |
+| `:2022` reverted | `test_the_walk_finds_a_store_only_project_from_a_subdirectory` | **GREEN — independent** |
+
+R4 is the anti-vacuity pass on both: had either new site been satisfied by
+something other than the store branch of `configured`, breaking that branch would
+have left it green.
+
+### The reviewer's X4 — a documented reason value with no guard
+
+The V4 review ran five mutations of its own; four were red and one was **green**:
+collapsing `config_store_settings`'s
+`(CONFIG_FROM_STORE if out else CONFIG_STORE_DEFAULT)` to `CONFIG_FROM_STORE`
+left all 38 tests passing. `store-default` is documented in `parsers.py` as its
+own reason and named in `parse_config`'s docstring as one of the five values
+`settings_source` can take, so a usable store carrying zero setting records would
+have reported `store` — truthful-looking and wrong about which question it
+answered — with nothing watching.
+
+**It gets a guard** (`TestAStoreThatDeclaresNoSettingsSaysSo`), at both levels:
+the predicate (`config_store_settings` on a track-only store) and the payload
+field (`parse_config(...)["settings_source"]`), because the payload field is
+where a reader actually sees it. R3 and R5 are red.
+
+**Two of them were not guards until the mutation said so**, and both were
+repaired rather than explained:
+
+1. `test_it_returns_non_zero_on_a_store_it_cannot_read` stayed green when the
+   `if findings:` refusal was disabled. Its fixture truncates the last JSONL
+   line, which `load_store` rejects before validation is reached — so it was
+   guarding the JSON decode and nothing else. The two branches are separate
+   cases now (`02dc442`).
+2. The same test then stayed green when `except (OSError, ValueError)` was
+   narrowed: the decode escaped as an uncaught exception, and **a traceback
+   also exits non-zero**. `assertNotEqual(rc, 0)` cannot tell a refusal from a
+   crash. It names the refusal message and forbids a traceback now (`b0d8cde`).
+
+## What the fixtures had to say, and why none of it was accommodation
+
+- **`tests/gate.py § GATE_OFF` appended to a config that already has `##`
+  sections mints no store record.** `scan_config` stores settings written above
+  the first `##` — deliberately, because a real config's prose sections are
+  full of bullets carrying a colon that are sentences and not keys — while the
+  old `gate_mode` regex scanned the whole file and found the line anywhere.
+  Four fixtures were appending. `gate_off(text)` puts the line in the preamble.
+- **A hand-built store has to say the opt-out too.** `gate_off_record()` is
+  that line; `GOOD_STORE`, `SETTING_ONLY` and `test_work_modes`'s
+  `_STORE_TRACKS` carry it.
+- **`test_md_store § test_config_including_its_prose_section`** asserted that
+  prose renders untouched by naming a section this repository happened to
+  carry. Repaired the way `test_okr`'s `assertGreater(len(krs), 20)` was
+  (TASK-150): the property moved onto a document the test writes, including the
+  bullet-with-a-colon case.
+- **`test_router_budget`** caught `SKILL.md` 657 bytes over its 20480 cap. The
+  two edits are one line each now, detail in `reference/config.md`, 20470 bytes.
+- **`test_procedures_call_the_tool`** flagged the first draft of `SKILL.md:195`
+  under R1.
+- **`test_live_state_expectations`** flagged 19 new sweep hits. Judged and
+  recorded, not waved through: all nineteen are one shape — the new module
+  binds `bin/perry-state` and `bin/perry-conform` through `load_bin_module`,
+  which reads them out of `bin/`, so the sweep taints every value they return
+  including ones computed entirely inside a tempdir the test just built. The
+  floor's docstring says so now instead of still claiming four entries. Every
+  entry in the floor is still judged `false positive`; none is an `instance`.
+
+## Baselines — runner, tree, and hour
+
+> **Round 1's "2 failures" was a figure of a tree and an hour, not of the
+> branch, and it was not labelled as one.** Re-measured for round 2 on named,
+> dated, disposable trees. The V4 reviewer got **3** where round 1 got 2; the
+> extra one is data-dependent on live board state, and re-measuring reproduces
+> the reviewer's three, not round 1's two.
+
+Runner `bash tests/run` (step 2 is `tests/parallel`, 8 workers). `PERRY_HOME`
+set to the tree under test in every run. Each tree is a **fresh `git archive`
+extract** into `…/scratchpad/`, carrying the board state committed on that
+commit and no uncommitted state from any checkout.
+
+| tree | commit | started | modules | tests | failures |
+|---|---|---|---|---|---|
+| `base-r1` | `632c198` — round-1 tip, **before** | 2026-08-30 04:41 CST | 101 | 3031 | **3** |
+| `base-r2` | `40eb4cc` — round-2 fix, **after** | 2026-08-30 04:41 CST | 101 | 3037 | **4** — see below |
+| `base-r3` | `d1deefb` — round-2 final, **after** | 2026-08-30 04:49 CST | 101 | 3037 | **3 — the same three** |
+
+`r1` and `r2` ran concurrently on one machine, so their wall-clock (414.8s /
+410.0s) is contended and not comparable to `r3`'s 272.9s. Delta from `632c198`
+to `d1deefb`: **+0 modules, +6 tests, 0 new failures.**
+
+The three, identical in `base-r1` and `base-r3`, and none of them this row's:
+
+- `test_diagnose § test_the_queue_register_reconciles_with_the_queue_on_this_repository`
+  (`3 != 1 : diagnose and perry-task disagree about how many queue rows are
+  waiting on the user`)
+- `test_diagnose § TestUserLoadFindings.test_perry_itself_passes_its_own_id_checks`
+  (`['ACTION-7', 'D009-1', 'D010-2', 'PROJ-003', 'SPEC-007'] != []`)
+- `test_kr_progress_provenance § TestBothOfTodaysWrongReadingsFlip.test_no_current_in_the_payload_claims_to_be_a_measurement`
+  (`the register carries no asserted current`)
+
+**The first one is why round 1's number was wrong.** It reconciles the queue
+register against the live board, so its verdict is a property of what the board
+says at the moment it runs, not of the branch. Round 1 measured before the
+board moved and reported 2; the reviewer measured after and got 3; round 2's
+`base-r1` — the *same commit* round 1 measured — now also gives 3. **The commit
+did not change. The board did.** A failure count with no tree and no timestamp
+beside it is not a measurement, and round 1's table gave neither.
+
+**`base-r2` had a fourth failure and it WAS this row's.**
+`test_live_state_expectations § test_the_floor_is_not_claimed_to_be_zero`, 24
+sweep hits against a recorded floor of 23. The new hit was the X4 guard's
+control asserting `values["document_language"] == "English"` — a false positive
+(the value came out of a tempdir the test had just built) but a redundant
+assertion, so it became `assertIn` rather than a 24th floor entry (`d1deefb`).
+It is listed here rather than quietly fixed because a suite run that goes red in
+a module the before tree did not is exactly what the before/after pair exists to
+catch, and it caught one.
+
+**These numbers differ from the dispatch's, and the difference is the tree and
+the hour.** The dispatch cites 98 / 2882 / 3 on a `git archive` copy of an
+earlier `main`, and separately 5 on a tree carrying live board state. Neither
+was re-measured here; the before/after pair above is measured on two trees at
+one commit each, with one runner, and is the comparison this row rests on. The
+`python3 -m unittest discover -s tests` delta of 3 remains unmeasured — see
+below.
+
+## What I did not do, and what I could not verify
+
+- **`perry/BOARD.md` and `perry/tasks.jsonl` are untouched.** The PMO owns
+  them. No `perry-task`, `perry-tasks`, `perry-goals`, `perry-decide` or
+  `perry-conform declare` was run anywhere, on any tree.
+- **`perry-conform declare` was not run for the user** (`SKILL.md:197`).
+- **`.perry/config.md` was not deleted.** Out of scope by the spec, and the
+  file survives all three deliverables. What changed is that its prose moved
+  and it is now exactly what the store renders.
+- **A `render --write` that recreates a deleted `.perry/config.md` is not
+  gated. The behaviour is pre-existing; the reachability is not.** The V4
+  reviewer confirmed both halves and corrected the framing: before this row,
+  `render` with no file exited 2, so no `config` write could ever reach an
+  `ABSENT` verdict. This row makes that path reachable for the first time. The
+  reviewer ruled it non-blocking and said it belongs in the filed intake row's
+  text.
+  `perry-conform § verdict` returns `ABSENT` for a file that is not on disk and
+  `ABSENT` is `ok`, so the write proceeds even under `enforce` on a project
+  where `.perry/config.md` is declared (it is, at shape version 2, in this
+  repository). Restoring a missing projection arguably should not be blocked,
+  but the reasoning is the gate's, not this row's, and nobody has written it
+  down. Worth a row if it is not wanted.
+- **`--dry-run` was not trusted on `perry-tasks`** and was not used at all.
+  Every destructive check ran on a `tar` copy of the tree, never on the tree.
+- **The archive baseline (98 / 2882 / 3) was not reproduced.** I measured
+  before-and-after at two commits instead. The V4 reviewer ruled this
+  non-blocking and made the sharper point: chasing that figure is a trap,
+  because the failure count moves with the board.
+- **The `discover` vs `tests/run` delta of 3 was NOT measured on this tree.**
+  One serial `python3 -m unittest discover -s tests` run was started and killed
+  unfinished after ~25 minutes, by which point it also predated two of the
+  commits. The V4 reviewer tried the same thing on a clean clone under a
+  40-minute cap and also hit the cap with no `Ran N tests` line — the gap was
+  reproduced, not closed, and round 2 did not retry it. There is no `discover` number in this report and the dispatch's
+  delta-of-3 is neither confirmed nor contradicted here. The `bash tests/run`
+  before/after pair is the whole of the evidence for "no regression".
+- **Other markdown-as-truth readers were not exhaustively swept — and in round 1
+  I said this correctly here while contradicting it in § 4.** I converted the two
+  the deliverable names, plus `resolve_state_root`, plus the four existence
+  checks in `d32ec76` and the two in `40eb4cc`. `bin/perry-diagnose §
+  scan_work_modes` was already converted by TASK-095. **Still unconverted and
+  named, not swept:** `bin/perry-diagnose:1373` and `:2501` (existence checks),
+  `bin/perry-lint:637 § track_context` (TASK-095's class, out of scope by the
+  spec), `bin/perry-migrate:228 § document_language` (a value-reading regex
+  returning `"en"` when the file is absent — the V4 reviewer read it and it is
+  the same kind as the `parse_config` defect this row fixed). The adoption path
+  was not read. The grep I ran (`re.search` / `read_text` / `exists()` against
+  `config.md` across `bin/` and `viewer/`) is a heuristic, not a proof — and
+  round 1's mistake was not this paragraph, it was writing a completeness claim
+  in § 4 that this paragraph's own grep falsifies.
+- **The two `bin/perry-diagnose` existence checks were not converted** — see
+  § 4. Named, counted, reproducible in principle by the same fixtures; not done.
+  `bin/perry-diagnose` does not import `parsers`, so it is an import change plus
+  two guards, which is a row.
+- **Nothing was measured on a second real project.** `~/proj/gimegime-pmo` is
+  referenced throughout `perry_md_store` as the second corpus and I did not
+  touch it — every measurement here is on Perry's own files or on fixtures.

+# TASK-233 — V4 review, round 2
+
+**PASS.**
+
+Reviewed `coding/task-233-config-readers` at `812f276` (worktree
+`…/scratchpad/review-233r2`, read-only). Every destructive check ran on my own
+`git archive` extracts under `…/scratchpad/rj233/`; nothing was written into the
+reviewed tree, no write-side Perry tool was run anywhere, and
+`perry-conform declare` was not run.
+
+Round 1's blocker is closed, and closed in the form the block asked for: the two
+`bin/perry-state` sites are converted, each carries its own named guard, the two
+guards are provably not one guard, and the residue is declared as a **count**
+with the command that produces it rather than as a sweep.
+
+---
+
+## 1 — Both sites closed, each with its own guard, and the guards are independent
+
+Reproduced the round-1 defect first, on my own extract of `632c198` with
+`.perry/config.md` deleted, store untouched, `PERRY_PROJECT` unset,
+`PERRY_HOME` = the extract, cwd a subdirectory:
+
+    $ (cd subdir && python3 ../bin/perry-lint | head -1)
+    perry-lint · …/rj233/demo-r1 (state root: perry/)          ← converted walk finds it
+    $ (cd subdir && python3 ../bin/perry-state --json)
+    root=       …/rj233/demo-r1/subdir
+    installed=  False
+    warnings=   ['No Perry state found — run /perry for first-time setup.']
+
+Exactly the string the row quotes as its own justification, still produced one
+file over. Same commands on `812f276`:
+
+    root= …/rj233/demo-r2/perry   installed= True   warnings= []
+    settings_source= store        tracks_source= store
+
+**The independence cross-check reproduces both halves.** My own driver
+(`…/scratchpad/rj233/rj_v4_mut.py` — unique name, outside the repo; refuses a
+non-unique anchor, asserts the target GREEN and selector > 0 tests before
+mutating, clears `__pycache__`, sleeps past the mtime boundary, restores from
+captured text and asserts md5):
+
+| mutation | selector | result |
+|---|---|---|
+| revert `resolve_root` walk (`bin/perry-state:2616`) | `test_the_installed_gate_counts_a_store_only_project_as_installed` | **GREEN — independent** |
+| revert `build` gate (`bin/perry-state:2026`) | `test_the_walk_finds_a_store_only_project_from_a_subdirectory` | **GREEN — independent** |
+
+The author's conclusion is correct: one test covering both would have been a
+false guard. The reason each needs what it needs also holds on reading — the
+walk's `cwd` fallback hides the walk from the project root itself (hence cwd
+below it, with `BOARD.md` parked at the *state* root so the walk's first
+disjunct cannot answer), and the gate needs `--root` plus a project with no
+`BOARD.md` / `OKR.md` / `design/DESIGN-*.md` so its other disjuncts cannot.
+
+## 2 — Mutations: 5 of 5 RED, reproduced on my own driver
+
+All five, not a spot-check. Every one md5-verified restored; driver printed
+`ALL RESTORED, md5-verified`.
+
+| # | mutation | anchor | pre | post | reddened |
+|---|---|---|---|---|---|
+| R1 | walk reverts to the markdown test | `bin/perry-state:2616` | GREEN | **RED** | `test_the_walk_finds_a_store_only_project_from_a_subdirectory` |
+| R2 | `installed` gate reverts | `bin/perry-state:2026` | GREEN | **RED** | `test_the_installed_gate_counts_a_store_only_project_as_installed` |
+| R3 | X4 — `store-default` collapsed into `store` | `viewer/parsers.py:356` | GREEN | **RED** | `test_a_store_with_no_setting_records_says_store_default` |
+| R5 | X4 again, payload selector alone | `viewer/parsers.py:356` | GREEN | **RED** | `test_the_distinction_reaches_the_payload` |
+| R4 | `configured` forgets the store | `viewer/parsers.py:401` | GREEN (3) | **RED** | **both** `TestPerryStateAsksItToo` site tests |
+
+## 3 — X4 is guarded at both levels
+
+`TestAStoreThatDeclaresNoSettingsSaysSo` asserts the predicate
+(`config_store_settings` on a track-only store → `({}, CONFIG_STORE_DEFAULT)`)
+and the payload (`parse_config(...)["settings_source"]`). R3 reddens the
+predicate test, R5 the payload test independently. Neither is vacuous: the
+predicate test asserts `values == {}`, which a `None` (unusable store) return
+would fail, so the fixture is proven to parse.
+
+## 4 — Every guard here fails under some mutation, including both controls
+
+Six tests were added in round 2. Five are covered by R1–R5; the two *controls*
+are not, so I mutated for them:
+
+| test | mutation that reddens it |
+|---|---|
+| `test_the_walk_finds_a_store_only_project_from_a_subdirectory` | R1 |
+| `test_the_installed_gate_counts_a_store_only_project_as_installed` | R2 |
+| `test_a_store_with_no_setting_records_says_store_default` | R3 |
+| `test_the_distinction_reaches_the_payload` | R5 |
+| `test_the_markdown_alone_still_counts` (control) | **Z1** — `configured` forgets the markdown → RED |
+| `test_a_store_with_setting_records_says_store` (control) | **Z2** — settings loop stops matching `kind: setting` → RED |
+
+No guard here survives its own deletion, and neither control is a control that
+cannot fail.
+
+**No new test is green for the wrong reason.** Checked against the known modes:
+no fixture parses zero rows (R3/R4 would have stayed green if any did); no test
+greps its own source or asserts a substring over a whole file; no test builds
+the dangerous state and then asserts something safe (both site tests assert on
+`installed` / `project.root` from the real entry point, out of process); and
+**no new fixture edits config markdown to change behaviour** — the two site
+fixtures set `markdown=None` / `store=False`, which is presence, not content.
+`run_state` strips `PERRY_PROJECT` (which would short-circuit the walk) and
+pins `PERRY_HOME` to the tree under test; both are necessary and both are there.
+
+## 5 — The re-run grep: count and classification verified
+
+    $ grep -rn "config\.md" bin viewer | grep 'exists()\|is_file()'
+    bin/perry-diagnose:1373:  "config": (root / ".perry" / "config.md").is_file(),
+    bin/perry-diagnose:2501:  is_perry = (root / ".perry" / "config.md").is_file() or (
+    bin/perry-lint:637:       if (root / ".perry" / "config.md").is_file():
+    bin/perry-goals:2177:     if not (perry / "config.jsonl").exists() and not (perry / "config.md").exists():
+    viewer/parsers.py:401:    return (perry / "config.jsonl").exists() or (perry / "config.md").exists()
+
+Five hits — the reported count. Each classification checked by reading it:
+
+- `viewer/parsers.py:401` — is `configured` itself. Correct.
+- `bin/perry-goals:2177` — the wide form inlined (TASK-095). Correct.
+- `bin/perry-diagnose:1373` — `perry["config"] = …is_file()`, then
+  `perry["installed"] = perry["config"] or (okr and board)`. **Narrow, and it is
+  the same existence-as-configured shape.** Correct, and NOT converted.
+- `bin/perry-diagnose:2501` — `is_perry = …is_file() or (OKR and BOARD)`.
+  Same. Correct, and NOT converted.
+- `bin/perry-lint:637 § _track_context` — TASK-095's class; it walks up to find
+  `.perry/config.md` and then reads `## Tracks` **out of that file as truth**.
+  The classification is right, and I note the walk inside it is the same shape:
+  converting the walk alone would be meaningless because the read that follows
+  needs the file itself.
+
+The stated reason for deferring `bin/perry-diagnose` checks out: that file
+imports `lib` and `tables`, **not `parsers`** (`grep '^import|^from' bin/perry-diagnose`
+shows no `parsers`), and it carries its own mirror of the state-root resolver
+(`:967` comment). Two guards plus an import change is a row, not a line.
+
+## 6 — Baselines, my own trees and my own hours
+
+Fresh `git archive` extracts, `PERRY_HOME` = the tree under test, runner
+`bash tests/run` (step 2 = `tests/parallel`, 8 workers). The two ran
+concurrently, so wall-clock is contended; the failure sets are the measurement.
+
+| tree | commit | started | modules | tests | failures |
+|---|---|---|---|---|---|
+| `…/rj233/t-632c198` | `632c198` round-1 tip | 2026-08-30 **05:01:44 CST** | 101 | 3031 | **3** |
+| `…/rj233/t-812f276` | `812f276` branch tip | 2026-08-30 **05:01:46 CST** | 101 | 3037 | **3 — the same three** |
+
+Delta **+0 modules, +6 tests, 0 new failures**. The author's `632c198` →
+`d1deefb` pair (101/3031/3 → 101/3037/3) reproduces exactly; `812f276` adds only
+report commits over `d1deefb`.
+
+The three, byte-identical between the two runs:
+
+- `test_diagnose § test_the_queue_register_reconciles_with_the_queue_on_this_repository`
+  — `3 != 1 : diagnose and perry-task disagree about how many queue rows are waiting on the user`
+- `test_diagnose § TestUserLoadFindings.test_perry_itself_passes_its_own_id_checks`
+  — `['ACTION-7','D009-1','D010-2','PROJ-003','SPEC-007'] != []`
+- `test_kr_progress_provenance § …test_no_current_in_the_payload_claims_to_be_a_measurement`
+  — `the register carries no asserted current`
+
+**Round 1's "2 failures" does not reproduce at `632c198`; I get 3**, which is
+what the round-1 reviewer also got (their review records 101/3031/3 on a clone
+at the same commit). So the correction stands. One nit on the *wording*: on a
+`git archive` extract the board is pinned to the commit, so "the commit did not
+change; the board did" cannot be the mechanism for an archive measurement — what
+is actually shown is that round 1's 2 came from a **different tree** (a live
+checkout carrying uncommitted board state), which is the same lesson and is why
+naming the tree matters. Conclusion unaffected.
+
+## 7 — The explanation of how § 4's false claim got past round 1: both halves true
+
+**Half one — "round 1 had no test that ran `bin/perry-state` for this property
+at all."** Verified the strong way rather than by reading. On a fresh extract of
+`812f276` I reverted **both** sites and ran the whole suite
+(`…/scratchpad/rj233/run-bothreverted.log`, started 05:08 CST):
+
+    101 modules · 3037 tests · 171.3s · 8 workers
+    ✗ test_config_store_readers.py
+        FAIL: TestPerryStateAsksItToo.test_the_installed_gate_counts_a_store_only_project_as_installed
+        FAIL: TestPerryStateAsksItToo.test_the_walk_finds_a_store_only_project_from_a_subdirectory
+    ✗ test_diagnose.py            (the two pre-existing)
+    ✗ test_kr_progress_provenance.py (the one pre-existing)
+
+Across 3,037 tests, **the only thing that notices the defect is the class round 2
+added.** Round 1's suite contained no guard for it, which is exactly the claim.
+`tests/test_config_store_readers.py` at `632c198` reaches `perry-state` only
+through `load_bin_module` (in process) and never as a subprocess.
+
+**Half two — the docstring carried the same false claim and is corrected.**
+`viewer/parsers.py § configured` at `632c198` ended
+`…already asked it the wide way; these are the rest.` At `812f276` it says six,
+splits them by round, and names `bin/perry-diagnose § scan_tracking` and
+`§ diagnose` as **NOT converted**. Both halves hold, so the explanation is worth
+what it claims to be.
+
+## 8 — The self-caught false positive: `assertIn` was the right call
+
+Reproduced the trip. On a fresh extract of `812f276` I restored the round-2
+first-draft assertion:
+
+    -        self.assertIn("document_language", values)
+    +        self.assertEqual(values["document_language"], "English")
+
+    $ python3 -m unittest discover -s tests -p test_live_state_expectations.py
+    - ["tests/test_config_store_readers.py:533  "
+    -  "TestAStoreThatDeclaresNoSettingsSaysSo.test_a_store_with_setting_records_says_store\n"
+    -  "    assertEqual(<live>, 'English')\n"
+    -  "    live: values['document_language']"]
+    AssertionError: 24 != 23 : the recorded floor and the live sweep disagree
+    FAILED (failures=2, skipped=3)
+
+24 against 23, from that assertion, exactly as reported.
+
+**`assertIn` did not weaken a real check.** Three reasons, each checked:
+
+1. The value is asserted elsewhere at the level a reader actually consumes it —
+   `TestParseConfigReadsTheStore.test_every_setting_comes_from_the_store_when_both_are_there`
+   asserts `cfg["language"] == "English"` through `parse_config`, which reaches
+   the same `config_store_settings` dict via `SETTING_FIELDS`. A wrong value
+   there still reddens.
+2. The **discriminating** half of this control — `assertEqual(why, CONFIG_FROM_STORE)`
+   — is untouched, and it is the half that makes it a control for
+   `…_says_store_default`.
+3. The control can still fail: Z2 (settings loop stops matching `kind: setting`)
+   reddens it *through the `assertIn`*.
+
+Recording a 24th floor entry to keep a redundant assertion would have been the
+worse trade, and naming it in the report rather than fixing it quietly is the
+behaviour the before/after pair exists to produce.
+
+## 9 — Other claims spot-checked
+
+- **Byte comparison.** On my own extract: original `.perry/config.md` md5
+  `cf1756f695ebd119784d8af4befc3a32`; deleted; `perry-config render --write --root .`
+  → exit 0, `9 stored record(s)`; rebuilt md5 `cf1756f695ebd119784d8af4befc3a32`,
+  `cmp` clean. Reproduced.
+- **The spec's corrected item 1.** On an extract of the fork point `658e8c9`
+  with the file deleted: `render --root . >/dev/null 2>&1` → **exit 2**; the same
+  command piped into `head` → **exit 0**. The PMO's error and its mechanism both
+  reproduce; the author's correction is right.
+- **Nothing PMO-owned was touched.** `git diff 658e8c9..812f276 --stat` shows no
+  `perry/BOARD.md`, no `perry/tasks.jsonl`, no `.perry/events.jsonl`.
+
+---
+
+## Ruling: is a declared `bin/perry-diagnose` count an acceptable way to close a row whose KR counts call sites?
+
+**Yes, in the form it takes here — and only in that form.**
+
+`P003-O2-KR1` is *"call sites in `bin/` that read a projected markdown file as
+truth while its store exists"*, target 0. Two `bin/perry-diagnose` sites remain
+in that category on the author's own reading, so **the KR is not at 0 after this
+row and the goals lane must not read the row's closure as the KR being met.**
+
+A row is closed against its spec, not against its KR. The spec named three
+deliverables and put `## Tracks` out of scope; all three are delivered and
+verified. What blocked round 1 was never the non-zero number — it was the
+sentence *"these were the rest"*, a completeness claim with no measurement
+behind it. Round 2 replaces it with a count, the command that produces it, a
+per-hit classification I re-derived independently and agree with, and a stated
+reason the residue is a row rather than a line (`bin/perry-diagnose` does not
+import `parsers`). That is the honest closing form, and the author's derived
+rule — *"these were the rest" is a measurement, needing a command whose output
+is the empty set, or it should be written as a count* — is the right rule.
+
+**One condition on the PASS, for the PMO and not for the author:** the two
+`bin/perry-diagnose` sites exist only in this report. No board row on this branch
+carries them, and the author correctly did not file one. If the PMO merges
+without filing that row, the count becomes evidence nobody is counting — which
+is the same failure mode one register over. `bin/perry-migrate:228 § document_language`
+(a value-reading regex returning `"en"` with the file absent — the same class
+`parse_config` just fixed) is named in the same paragraph and belongs in the
+same row or its own.

+## checked / not-checked
+
+**checked (all on my own `git archive` extracts, never the reviewed tree):**
+the two conversions and their before-state reproduction at `632c198`; all five
+declared mutations with md5-verified restore; both independence cross-checks;
+two mutations of my own for the two controls; the whole-suite run with both
+sites reverted (the decisive test of "round 1 had no guard"); the re-run grep,
+its count and each of its five classifications; `bin/perry-diagnose`'s imports;
+both baselines with tree and hour; the byte-identical rebuild and its md5; the
+fork-point exit-code correction, piped and unpiped; the `assertIn` decision,
+including reproducing the 24-vs-23 trip; `parsers § configured`'s docstring
+before and after; the branch's diffstat against the fork point.
+
+**not checked:**
+
+- **The 28 round-1 mutations** were not re-run. Round 1's review verified them
+  on its own driver and this round grades round 2's delta.
+- **`python3 -m unittest discover -s tests`** was not run. Two reviewers have now
+  hit the time cap on it; I did not retry, so the dispatch's `discover`-vs-`tests/run`
+  delta of 3 is still neither confirmed nor contradicted.
+- **The dispatch's archive baseline (98 / 2882 / 3)** was not reproduced. It is a
+  figure of an earlier `main`; my before/after pair is measured at two commits on
+  one runner and is what the no-regression claim rests on.
+- **Nothing was measured on a second real project.** `~/proj/gimegime-pmo` was not
+  touched.
+- **The prose relocation into `.perry/hook.md`** was not re-verified line by line;
+  round 1 confirmed the 29 lines verbatim and round 2 did not move them.
+
+## Non-blocking notes
+
+1. **Merge hazard.** The branch's own copy of `perry/evidence/2026-08/TASK-233-spec.md`
+   still reads *"prints `no .perry/config.md` and **exits 0** … Filed separately as
+   an intake row"*; `main`'s copy carries the PMO's correction (`9db8f45`). The
+   merge must keep **main's** text — a naive resolution in the branch's favour
+   would re-introduce a measurement the PMO has already retracted.
+2. **`Fixture.bare()`'s docstring describes work it does not do.** It says it
+   removes `BOARD.md` / `OKR.md` so a caller's OR-chain cannot answer for the
+   predicate, but `Fixture.project()` never creates either, so the two
+   `unlink(missing_ok=True)` calls are no-ops. The fixture *is* bare and the
+   guards are sound; the comment claims a step that is not happening, which is
+   the small version of the thing this row was failed for.
+3. **"The commit did not change. The board did."** — see § 6. True of the lesson,
+   not literally true of a `git archive` measurement at a pinned commit.

+# TASK-233 — `.perry/config.md` is load-bearing because of its readers, not its content
+
+> Filed 2026-08-29, dispatched 2026-08-30. Serves `P003-O2-KR1` — call sites in
+> `bin/` that read a projected markdown file **as truth** while its store exists.
+
+## Measured, 2026-08-29 at `7df879d`
+
+`.perry/config.jsonl` carries **all 9 records** — 7 settings and 2 tracks. Nothing
+structured in the markdown is missing from it.
+
+**But only `## Tracks` reads the store.** `bin/perry-state:115 parse_config`
+regex-scans the markdown for six settings and **early-returns an empty config
+when the file is absent**:
+
+```python
+path = root / ".perry" / "config.md"
+if not path.exists():
+    return cfg          # six settings become ""
+```
+
+`bin/perry-conform:304` reads the `Conformance gate` the same way.
+
+So deleting the file today silently blanks document language, chat language,
+repo layout, state root and both repo paths, and drops the gate to the shipped
+default. That is not a hypothetical: `SKILL.md:89` treats an absent
+`.perry/config.md` as *"prompt for first-time setup"*, so an absent markdown
+currently means **"this project was never configured"** rather than **"read the
+store"**.
+
+Two more things stand in the way, both measured:
+
+1. **`perry-config render` cannot rebuild the file from the store.** With it
+   deleted it prints `no .perry/config.md` and writes nothing — it is an
+   in-place cell updater, not the projection `BOARD.md` has.
+
+   **Corrected 2026-08-30: it exits 2, not 0.** The original text here said 0,
+   and that was a measurement error of the PMO's — the command was piped into
+   `head` and `$?` was read after the pipe, which reports `head`'s status and is
+   always 0. Re-measured on a copy: `render --root . >/dev/null 2>&1` gives **2**.
+   The refusal is correct and always was. The intake row filed against it has
+   been dropped with the same correction. What remains true, and is what this
+   deliverable is about, is that it cannot REBUILD the file — refusing loudly is
+   the right behaviour for a tool that cannot, and a different thing from being
+   able to.
+2. **27 of the file's 45 lines are prose the store has no field for** — what
+   `intake` carries versus `main`, why `Default rung` is V3 rather than queue
+   mode's V2, and why the state root is not `.` (the DESIGN-002 collision).
+
+`SKILL.md` names the file in six places, and `:195` records why its field names
+stay English in every language: **this file declares the language and must be
+readable before it is known.**
+
+## Deliverable
+
+Three things, and the file survives all three.
+
+1. **`parse_config` and `perry-conform` read `.perry/config.jsonl` when it
+   exists**, with the markdown as the fallback for a project that has no store —
+   the arrangement `## Tracks` already has. **An absent markdown stops meaning
+   "never configured".**
+2. **`perry-config render` rebuilds `.perry/config.md` from the store ALONE**,
+   with no target file present, and returns **non-zero** when it cannot.
+3. **The 27 lines of prose have a declared home that a render does not destroy** —
+   either moved to `reference/config.md`, which already exists and is where this
+   class of explanation lives, or preserved by a stated contract the renderer
+   honours.
+
+When all three hold, `.perry/config.md` is a projection in the same sense
+`BOARD.md` is, and whether it should exist at all becomes a question worth
+asking. It is **not** worth asking before then, because today the answer is
+forced by the readers rather than chosen.
+
+## Verification — V4
+
+1. **Delete `.perry/config.md`** on a project whose store is populated: every
+   setting still resolves, `perry-conform` still reports the declared gate rather
+   than the default, and `perry-config render --write` rebuilds the file.
+2. **Byte-compare the rebuilt file against the original, prose included** — or
+   state exactly which lines are not recoverable and where they went.
+3. **Mutation**: revert the store read in `parse_config` to the regex and show a
+   **NAMED** test goes red. The previous conversion of `## Tracks` shipped a
+   guard on the `perry-goals` side that could be deleted with the whole suite
+   unchanged, and it was removed for it — **a guard that does not fail when
+   removed does not count here.**
+4. Baselines name **both the runner and the tree**. On a `git archive` copy of
+   `main`, `bash tests/run` is 98 modules / 2882 tests / 3 failures; on a tree
+   carrying live board state it is 5, the two extra being
+   `test_contract_key_parity`'s data-dependent witness tests. `discover` differs
+   from `tests/run` by exactly 3 — `test_risks_store`'s double-import artefact —
+   measured on three trees on 2026-08-30.
+
+## Out of scope
+
+- **Deleting `.perry/config.md`.** That is the question this row makes askable,
+  not the question it answers — and `USER-903` already decided on 2026-08-28 that
+  the file becomes a rendered projection, which is a different decision from
+  removing it.
+- The `## Tracks` reader, which `TASK-095` owns and has already converted.

+# TASK-233 — V4 review — **FAIL**
+
+Reviewed at `632c198`, tip of `coding/task-233-config-readers`, against `main` at
+`658e8c9`. Read-only: every destructive check ran on `git archive` extracts or
+`git clone`s in my own scratch (`…/scratchpad/rv233/…`), never in the review
+worktree, never in `/Users/bytedance/proj/Perry`. No write-side Perry tool was
+run anywhere; `perry-conform declare` was not run.
+
+---
+
+## The defect
+
+**`bin/perry-state` still asks "is there a `.perry/config.md`" as its test for
+"is this configured", in two places, and the result claims those call sites were
+all found.**
+
+`perry/evidence/2026-08/TASK-233-result.md § 4` says:
+
+> **"An absent markdown stops meaning 'never configured'"** is the deliverable's
+> own wording, and four call sites were still deciding exactly that … `bin/perry-lint
+> § is_adopted` and its project-root walk, `bin/perry-explain`, and
+> `viewer/parsers.py § project_root`. … **these were the rest.**
+
+They are not the rest. On the branch tip:
+
+    bin/perry-state:2022   installed = ... or (perry_root / ".perry" / "config.md").exists()
+    bin/perry-state:2607   if ((d / "BOARD.md").exists() or (d / "OKR.md").exists()
+                                   or (d / ".perry" / "config.md").exists()):
+
+`:2607` is a byte-for-byte duplicate of the walk that WAS converted in
+`bin/perry-lint § main` (`P.configured(d)`) and in `viewer/parsers.py §
+_resolve_project_root` (`configured(d)`). `bin/perry-state` — the file the spec
+names first — kept its own copy.
+
+### Reproduction (branch tip, `.perry/config.md` deleted, store untouched)
+
+    $ cd …/scratchpad/rv233
+    $ cp -R br walk && rm walk/.perry/config.md && mkdir walk/subdir
+    $ cd walk/subdir
+
+    $ env -u PERRY_PROJECT PERRY_HOME=…/rv233/walk python3 ../bin/perry-lint | head -1
+    perry-lint · …/rv233/walk (state root: perry/)
+
+    $ env -u PERRY_PROJECT PERRY_HOME=…/rv233/walk python3 ../bin/perry-state --json
+    "project": { "root": "…/rv233/walk/subdir", "name": "subdir" }
+    "installed": false
+    "warnings": ["No Perry state found — run /perry for first-time setup."]
+
+Same tree, same cwd, same `PERRY_HOME`. `perry-lint` walks up and finds the
+project; `perry-state` does not, and emits **the exact string the author quotes
+as the defect that justified converting `resolve_state_root`**. Control, with
+the markdown present (`walk2`, otherwise identical):
+
+    "project": { "root": "…/rv233/walk2/perry" }, "installed": true, "warnings": []
+
+Second, independent site — `bin/perry-state:2022`, the `installed` gate. Two
+minimal projects, branch tool, `--root` given so the walk is not involved:
+
+    A: .perry/config.jsonl only   → installed=false, "No Perry state found — run /perry for first-time setup."
+    B: .perry/config.md   only    → installed=true
+
+A store-configured project reads as never configured; the same project
+configured by the projection reads as configured. That is the sentence the
+deliverable was written to remove.
+
+### Why this blocks
+
+1. **It is the deliverable's own wording, and the report asserts it is
+   finished.** A false completeness claim is worse than a declared gap; the
+   author's declared gap 4 covers *value-reading regexes* elsewhere, not the
+   *existence-check* class § 4 says it swept.
+2. **The row serves `P003-O2-KR1`, which counts call sites in `bin/`.** Two
+   uncounted sites in the file the spec names first make the KR's number wrong,
+   not merely incomplete.
+3. **The author's own declared grep would have found them.** `grep -rn
+   "config\.md" bin viewer | grep 'exists()'` returns both in one command; I ran
+   it and it took seconds.
+4. **`perry-state --json` with no `--root` is the primary documented
+   invocation** — `SKILL.md:130` (standup step 2), `work/SKILL.md:121`,
+   `work/reference/subcommands.md:109`, `modes/queue.md:273`. None passes
+   `--root`.
+
+**Reach, stated honestly:** the walk still falls back to `cwd`, so from the
+project root itself it recovers (I measured: `installed: true`, correct state
+root). The failure needs cwd to be a subdirectory of the project — a coding
+agent in `src/`, `bin/`, or the state root's siblings — or, for `:2022`, a
+project with a store and no `BOARD.md`/`OKR.md`/`design/DESIGN-*.md`. Narrow,
+reproducible, and in the one file the row is about.
+
+**The fix looks small**: `P.configured(...)` in both places, plus the two guards
+the author already wrote for the other four sites. `viewer/parsers.py §
+configured` exists and is the right predicate.
+
+### Two more of the same class, not blocking but naming the sweep's real size
+
+- `bin/perry-diagnose:2501 § is_perry` — `(root / ".perry" / "config.md").is_file()`.
+  Same existence-as-configured shape.
+- `bin/perry-migrate:228 § document_language` — a **value-reading regex** over
+  `.perry/config.md`, returning `"en"` when the file is absent. Identical in kind
+  to the `parse_config` defect this row fixed. **This one IS disclosed** by the
+  author's gap 4.
+- `bin/perry-lint:637–666 § track_context` — walks up five levels for
+  `.perry/config.md` and reads the `## Tracks` table out of it as truth. That is
+  TASK-095's class and the spec puts it out of scope, but it means the KR's
+  count is still non-zero for tracks as well.
+
+---
+
+## What I checked, and what I measured
+
+### The third reader — RULED: the author was right, and had to be
+
+I reproduced the justification on `main` at `658e8c9`, on a `git archive` copy
+with `.perry/config.md` deleted and the store untouched:
+
+    $ cd …/rv233/base-nomd
+    $ PERRY_HOME="$PWD" python3 bin/perry-state --root . --json
+    "installed": false
+    "warnings": ["No Perry state found — run /perry for first-time setup."]
+
+and directly, in `main`'s `viewer/parsers.py:256-258`:
+
+    cfg = project_root / ".perry" / "config.md"
+    if not cfg.exists():
+        return project_root
+
+Every Perry path resolved against the project root instead of `perry/`. The
+spec's V4 step 1 — *"every setting still resolves"* — **was unsatisfiable as
+written** without converting `resolve_state_root`. Converting an unnamed third
+reader was not scope creep; it was the only way the spec's own acceptance
+criterion could be honest, and the author says so in the code and in the result.
+
+**Placement argument holds.** `bin/perry-conform` cannot import a hyphenated
+`bin/perry-state` (it would load `perry-lint` on the way), and
+`resolve_state_root` runs before any tool starts. `viewer/parsers.py` is the
+bottom of the import graph. The lazy `import perry_md_store` inside
+`config_store_records` is necessary — `perry_md_store` imports `parsers` at
+module scope — and its `except Exception → unreadable` keeps a bad schema from
+becoming an ImportError in every tool.
+
+**The delegate is behaviour-preserving.** `bin/perry-state §
+_validated_config_records` now returns `P.config_store_records(project_root)`.
+Old and new differ only in `Path(project_root)` coercion and the `sys.path`
+insert for `bin/`; the classification chain is identical (`absent` → exception
+`unreadable` → `findings` `invalid` → empty `invalid` → `(good, "")`), the name
+and the three `TRACKS_STORE_*` constants are unchanged, and
+`test_config_store_readers § TestTheTwoNamesForOneReason` asserts the two
+spellings are the same four objects. Mutation M7 reddens it.
+
+### V4 claim 1 — CONFIRMED (my own copy, branch tip)
+
+`.perry/config.md` deleted, store untouched, `…/rv233/br-nomd`:
+
+- `perry-state --root . --json § project.config`: `present: true`,
+  `language: English`, `chat_language: 中文`, `layout: single`,
+  `state_root: perry`, `pmo_repo: /Users/bytedance/proj/Perry`,
+  `code_repo: —` (the marker, not `""`), `settings_source: store`,
+  `tracks_source: store`, tracks `[main, intake]`, `warnings: []`.
+- `perry-conform status` → `gate: enforce` (Perry declares none; that is the
+  shipped default). I then **added** `conformance_gate: advisory` to the store,
+  markdown still absent → `gate: advisory`. The declared gate beats the default
+  and comes out of the store. Store restored afterwards.
+
+### V4 claim 2 — CONFIRMED, md5 reproduced
+
+    $ md5 .perry/config.md            # before deleting
+    cf1756f695ebd119784d8af4befc3a32
+    $ rm .perry/config.md
+    $ PERRY_HOME="$PWD" python3 bin/perry-config render --write --root .
+    perry-config: rendered …/.perry/config.md from 9 stored record(s)   exit=0
+    $ cmp ../rv233-orig-config.md .perry/config.md   → identical
+    $ md5 …
+    MD5 (../rv233-orig-config.md)  = cf1756f695ebd119784d8af4befc3a32
+    MD5 (.perry/config.md)         = cf1756f695ebd119784d8af4befc3a32
+
+**The spec correction is also confirmed.** On `main` at `658e8c9`, same copy,
+markdown deleted: `perry-config render --write` prints `no .perry/config.md` and
+exits **2**, not 0. The author corrected the spec correctly.
+
+### V4 claim 3 — scaffold checked, not trusted: I tried to make it write wrong
+
+Five hand-broken scaffolds fed through `M.main` on a copy:
+
+| what I broke | result |
+|---|---|
+| a setting's **value** changed | **refused, exit 2**, `first_difference` names line 5 |
+| a setting **dropped** | **refused, exit 2**, `records_not_in_the_file: ["setting/repo_layout"]` |
+| a track row **dropped** | **refused, exit 2**, `records_not_in_the_file: ["track/intake"]` |
+| the table's **columns swapped** | refused (the author's own M4/test) |
+| **extra prose appended** | **written, exit 0** |
+| the **title** changed | **written, exit 0** |
+
+The last two escape the round trip — correctly, given what it is: `render()`
+passes layout through untouched by design, so bytes that are layout cannot move,
+and `records_not_in_the_file` only reports store records with no line, never a
+line with no record. The author's claim is scoped exactly to those two
+conditions and is accurate. The title and the absence of stray prose are pinned
+elsewhere, by `test_perrys_own_config_round_trips`, which compares
+`scaffold_config(records)` to Perry's real file — I confirmed with my own
+mutations X2 (settings emitted in reverse order) and X3 (`CONFIG_TITLE`
+changed), both **RED**.
+
+`OKR.md` has no scaffold (`M.OKR.scaffold is None`) and `perry-okr render`
+refuses with a message; mutation N11 (give OKR the config scaffold) is RED.
+
+### V4 claim 4 — the prose: CONFIRMED verbatim, 29 lines
+
+`git diff 658e8c9 632c198 -- .perry/config.md` removes exactly 29 lines (spec
+said 27; the result corrects it). Diffing the removed block against
+`.perry/hook.md § Configuration notes` is **identical**, with two disclosed
+changes the result itself names: `## Why the state root is not `.`` is demoted to
+`###`, and a new `### What the two tracks carry` heading is added over the first
+paragraph. The general rule is at `reference/config.md § Prose in this file is
+layout, and `.perry/hook.md` is where it belongs`, and it states the two halves
+of the contract honestly — settings and rows recoverable, prose not.
+
+**DESIGN-013 § 5.5 is honoured.** § 5.5 rejects *"Move prose into the stores"* by
+name; the row moves prose to a document that is rendered from nothing, which is
+§ 5.1's split by file. Nothing prose-shaped entered `.perry/config.jsonl` — the
+store is the same 9 records before and after.
+
+### V4 claim 5 — the mutation harness: "≥1 test selected" EXISTS
+
+`task233_mutation_harness.py:150-157` refuses a dirty tree at start;
+`:176-184` runs the target, refuses on `rc != 0` ("TARGET NOT GREEN BEFORE
+MUTATION") **and on `green_n <= 0` ("TARGET SELECTED n TESTS")**, where `green_n`
+is parsed from unittest's `Ran N tests`. Harnesses 2 and 3 carry the same two
+checks. Anchors are matched by exact text with a uniqueness check; restore is
+md5-verified. The assertion the prompt asked about is there.
+
+### V4 claim 6 — 28 mutations, 28 red, and every one of the 38 tests reddened
+
+I did **not** take the author's numbers. I wrote my own driver
+(`…/scratchpad/rv233/rv233_reviewer_mut.py`), extracted the 28 mutation anchors
+from the three harnesses, and ran each against a **clean `git clone` at
+`632c198`** — full-module runs, no `-k` selector, capturing the exact FAIL/ERROR
+set each time.
+
+- baseline: **38 tests GREEN**
+- **28 of 28 mutations RED.** Every one names its test; my reddened sets match
+  the result's table row for row.
+- **Every one of the 38 tests is reddened by at least one mutation.** The union
+  covers all 35 distinct short names; the three copies of
+  `test_a_project_with_no_store_still_reads_its_markdown` are hit separately by
+  N1 (`parse_config`), N3 (`gate_mode`) and N5 (`declared_state_root`), and the
+  two copies of `test_the_store_wins_over_the_markdown` by M2 (gate) and M3
+  (state root) — one reddened test each, so the classes are distinguished.
+  **Nothing in the module is unwatched.** This is the strong property and it
+  holds.
+- tree CLEAN after every batch; restore md5 verified each time.
+
+**One arithmetic error in the report**: it says *"27 mutations, 27 red"* twice,
+but the table has **28 rows** and the three harnesses define 28 mutations. All 28
+are red; the count is wrong, not the claim.
+
+### V4 claim 7 — both repairs CONFIRMED
+
+1. `test_it_returns_non_zero_on_a_store_it_cannot_read` and
+   `test_it_returns_non_zero_on_a_store_that_does_not_validate` are now two
+   tests over two branches. N10 (disable the `if findings:` refusal) reddens
+   only the validate one; **N10b** (narrow `except (OSError, ValueError)` to
+   `(OSError,)`) reddens only the cannot-read one. Before the split, one test
+   was guarding the JSON decode alone.
+2. The cannot-read test no longer says `assertNotEqual(rc, 0)` and stop. It
+   asserts `"store is not readable JSONL"` is in the output **and**
+   `"Traceback (most recent call last)"` is not. N10b is red because of that
+   pair; with `assertNotEqual` alone a traceback would have kept it green.
+
+### V4 claim 8 — baselines, runner and tree named
+
+Runner `bash tests/run`, `PERRY_HOME` = the tree under test, in both cases a
+**fresh `git clone` of `/Users/bytedance/proj/Perry` carrying no uncommitted
+board state**:
+
+| tree | modules | tests | failures |
+|---|---|---|---|
+| clone at `658e8c9` (`…/rv233/mutbase`) | **100** | **2992** | **3** |
+| clone at `632c198` (`…/rv233/mutafter`) | **101** | **3031** | **3 — the same three** |
+
+The three, identical on both sides:
+
+- `test_diagnose § TestUserLoadFindings.test_perry_itself_passes_its_own_id_checks`
+- `test_diagnose § test_the_queue_register_reconciles_with_the_queue_on_this_repository`
+  (`3 != 1 : diagnose and perry-task disagree about how many queue rows are waiting`)

+
+Module and test counts match the author's exactly. **The failure count does
+not** — 3 on my trees, 2 on the author's — and the extra one is the
+data-dependent queue-reconciliation test, exactly the class the dispatch warned
+about. It is red before and after, on both trees, so it is not this row's. Delta
+is **+1 module, +39 tests, 0 new failures**; the no-regression claim holds.
+
+### Guards that survive their own deletion — I found a third, minor
+
+Five extra mutations of my own. Four were RED (X1 the state-root escape guard,
+X2 scaffold ordering, X3 `CONFIG_TITLE`, X5 `settings_source`). One was
+**GREEN**:
+
+    X4  viewer/parsers.py § config_store_settings
+        return out, (CONFIG_FROM_STORE if out else CONFIG_STORE_DEFAULT)
+      → return out, CONFIG_FROM_STORE
+        38/38 STILL GREEN — NOT A GUARD
+
+`CONFIG_STORE_DEFAULT` ("store-default") is documented in `parsers.py` as its own
+reason and named in `parse_config`'s docstring as one of the five values
+`settings_source` can take. Nothing asserts it. A usable store carrying zero
+setting records would report `store` instead of `store-default` and no test would
+notice. **Minor** — the only consumer is a payload field, both values are
+truthful — but it is a documented distinction with no guard, and it is the third
+of the kind the author found two of.
+
+### Wrong-for-the-right-reason sweep — clean
+
+- No vacuous fixture: `TestRenderRebuildsTheFileFromTheStore` copies Perry's
+  real 9-record store, and `test_it_is_the_store_that_is_being_read_and_not_a_leftover_file`
+  is the explicit anti-vacuity companion (mutate a stored value, watch the
+  rebuild move).
+- No test greps its own source or docstring. `test_the_general_rule_names_the_home`
+  reads `reference/config.md`; `test_the_relocated_prose_is_in_the_hook` reads
+  `.perry/hook.md`; the searched sentences appear in neither test's own text.
+- No control that cannot fail: `test_neither_is_not` is reddened by O3.
+- **The config-markdown-editing fixtures are handled honestly.** `tests/gate.py`
+  gained `gate_off(text)` (inserts the opt-out in the *preamble*, where
+  `scan_config` looks) and `gate_off_record()` (says it in a hand-built store
+  too). Four fixtures — `test_unlinked_declaration`, `test_work_modes`,
+  `test_track_register_source § GOOD_STORE` and `SETTING_ONLY` — were appending
+  the line after a `##` heading, which minted no record and stopped working the
+  moment the reader converted. The docstrings say exactly that, including the
+  trap it avoids: a `SETTING_ONLY` store with no gate record makes every write
+  refuse on ADR-004 and turns `assertNotEqual(rc, 0)` into a green measuring
+  nothing.
+- `bin/perry-tasks --dry-run` was not used; nothing write-side ran.
+- `PERRY_HOME` was the tree under test in every command above.
+
+---
+
+## Ruling on the five declared gaps
+
+1. **`discover` not measured — DOES NOT BLOCK.** The delta-of-3 is a property of
+   `test_risks_store`'s double import, not of this row, and the `bash tests/run`
+   before/after pair on one tree with one runner is a sufficient no-regression
+   comparison. I started a serial `discover` on the after tree myself and it had
+   not finished when this review closed — see *not checked*. The gap is declared
+   accurately; the author says outright that the dispatch's delta is "neither
+   confirmed nor contradicted here", which is the correct thing to say.
+2. **Archive baseline (98/2882/3) not reproduced — DOES NOT BLOCK.** A
+   before/after pair on one tree is the right comparison for "did this row break
+   anything"; the archive figure answers a different question. My own
+   measurement (100/2992/3 → 101/3031/3) independently confirms the pair, and
+   also shows why chasing the archive number is a trap: I got a third failure
+   the author did not, purely from board data and the date.
+3. **`render --write` on a deleted declared file is not gated — DOES NOT BLOCK,
+   with one correction to the framing.** Confirmed: `.perry/config.md` is
+   declared at shape version 2 (`.perry/conformance.md:15`), `gate: enforce`, and
+   `render --write` recreated it at exit 0. Confirmed pre-existing:
+   `perry-conform § Verdict.ok` returns true for `ABSENT` and the diff touches
+   neither. **But the row makes the path newly reachable** — before it, `render`
+   with no file exited 2, so no `config` write could ever hit an ABSENT verdict.
+   That belongs in the filed intake row's text; it is not a reason to hold this
+   one.
+4. **Markdown-as-truth sweep not exhaustive — DOES NOT BLOCK ON ITS OWN, BUT SEE
+   THE DEFECT.** A row whose KR is a count should not be held for every
+   unconverted reader; converting them all is other rows' work and the author
+   named `bin/perry-migrate` and adoption as unread. What is not acceptable is
+   the *converted* class being declared complete when it is not — and that is the
+   FAIL above, which is a different sentence in a different section. Gap 4 is
+   declared honestly and I would have passed it.
+5. **Nothing measured on a second real project — DOES NOT BLOCK.** Not touching
+   `~/proj/gimegime-pmo` is correct under the read-only discipline, and the
+   fixtures cover the store/markdown divergence more sharply than a second real
+   project would.
+
+---
+
+## not checked
+
+- **`python3 -m unittest discover -s tests` was not completed on either tree.**
+  I started one serially on the after clone under a 40-minute cap; it hit the cap
+  without printing a `Ran N tests` summary, so I have no `discover` number
+  either. **I reproduced the author's gap rather than closing it** — the serial
+  runner really does take longer than a reviewer will sit for on this suite. The
+  `discover` vs `tests/run` delta of 3 is neither confirmed nor contradicted by
+  me.
+- **`bin/perry-migrate` and the adoption path were not read for surviving
+  value-reading regexes** beyond the grep reported above. I read
+  `perry-migrate:228` and stopped.
+- **No second real project.** Everything above is Perry's own files, `git
+  archive`/`git clone` copies of them, or fixtures.
+- **`perry-config verify` / `perry-lint` drift numbers on a markdown-less tree**
+  were checked only through `perry-lint`'s summary line, not field by field.
+- **The author's own harness runs were not re-executed**; I built my own driver
+  and my own mutation loop from their anchors, which is why the mutation
+  numbers above are mine.

+## 0 · What landed, in one paragraph
+
+The conformance record is a store: one JSON object per line, keyed on `path`,
+carrying the four facts the table carried and three the table could not —
+**which writer produced it, when to the second, and under which migration run**.
+`viewer/parsers.py § read_conformance` reads it and reads nothing else.
+TASK-241's markdown reader is kept **verbatim** as `read_legacy_conformance` and
+is a **conversion source, never a register**: no gate consults it, and the one
+caller is `perry-conform migrate`, a new subcommand that carries a pre-TASK-234
+record across with its dates and routes unchanged and deletes the markdown.
+There is no rendered markdown. `perry-conform status` was already the human
+surface. Perry's own record converted: 23 declarations, `status` unchanged
+before and after.
+
+---
+
+## 1 · Bootstrap order — settled before any code was written
+
+**The question.** The record gates every write under ADR-004's enforce gate,
+*including the write that migrates it*. The migration path must not require the
+gate to be passable mid-migration.
+
+**The answer, and it is not an exemption.** No writer has ever called `gate()`
+about the record, because `gate()` takes one schema-declared key and
+`state_files()` enumerates `schema/state-schema.json § files[]` — and the record
+is deliberately not a `files[]` entry (§ 2). So the record's own write is
+**ungated by construction**. The conversion needs no exemption and none is
+granted; an exemption would be a hole, and this is a file the gate has no
+opinion about. The self-reference decision and the bootstrap answer are the
+*same* decision seen from two sides, which is why the row asked for both.
+
+Measured, not asserted:
+`tests/test_conformance.py § TestTheRecordIsNotDeclarableAboutItself
+.test_no_writer_gates_on_the_record` walks `state_files()` on a live fixture and
+requires that neither record name appear in it, and that
+`verdict(<record>)` is `absent`.
+
+**What the gate does in the window.** A project that has only the markdown reads
+as `undeclared` — the store reader does not fall back — and the refusal names
+`perry-conform migrate`, **not** `perry-conform declare`. That branch sits
+*before* every other branch in `message_for`, because naming `declare` there
+would be a correct sentence about the store and a wrong instruction: it would
+mint a declaration dated today over one the user made on 2026-08-20.
+
+**Why no read-time fallback**, which was the other option and is what TASK-233
+did for `.perry/config.md`. A fallback is a second live register for the fact
+that gates every write, and it would carry TASK-248's hole (§ 5) for as long as
+any project left its markdown in place. Pinned by mutation **M7**: reintroducing
+the fallback reddens `test_the_markdown_alone_declares_nothing`.
+
+**`perry-conform migrate` is runnable by an agent, and `declare` still is not.**
+`SKILL.md:197` reserves the *declaration* to the user. `migrate` writes only rows
+that are already in the record — it cannot mint one — so a file the markdown did
+not declare is undeclared afterwards
+(`test_the_conversion_declares_nothing_the_record_did_not_hold`). **No
+`perry-conform declare` was run for the user anywhere in this row**; Perry's own
+record was converted with `perry-conform migrate`.
+
+**The one-way door has a lock.** The conversion refuses unless the markdown is
+line-for-line `render_legacy(read_legacy_conformance(file))`. That is the
+whole-file fixed point TASK-241 round 2 *rejected as a reading rule* — one stray
+blank line voids all 23 of Perry's declarations and takes the gate down — and it
+is the right rule here for the reason it was the wrong rule there: this runs
+once, the consequence of refusing is bounded and reversible, and the consequence
+of proceeding is a laundered declaration nothing downstream can tell from a real
+one. It also refuses when any row is unreadable, rather than dropping it (§ 5,
+TASK-246).
+
+`render_legacy` is the **original** `render()` moved, not a re-derivation: a
+check that "this file is what Perry wrote" is worth nothing if the right-hand
+side is a second, freshly-typed idea of what Perry wrote.
+
+**Line-for-line, not byte-for-byte, and round 1 claimed the stronger thing.**
+The comparison is against `Path.read_text()`, which applies universal-newline
+translation, so a record saved with CRLF converts. That is the behaviour we
+want — refusing a CRLF record would strand a Windows checkout with no way
+forward — but it is not what the word said. Corrected in
+`bin/perry-conform`, `bin/README.md` and here, and pinned by
+`test_a_crlf_record_converts_and_the_wording_does_not_say_byte`, which asserts
+the behaviour **and** that the source has stopped claiming the other one.
+
+**Round 4 — the guard's reach, decided rather than left.** The V4 round-3
+reviewer measured the guard as pinning one literal, `"byte-for-byte what"`, in
+one file: a reworded overclaim ("byte for byte", "byte-for-byte identical to
+what") walked past it, and `bin/README.md` — which documents the same
+conversion, for the same reader, in the same words — was not covered at all.
+**Decision: widen it.** It is now a regex for the phrase *describing what the
+file is compared against*, applied to both files, plus a positive pin on the
+correcting sentence in each, because deleting that sentence passes any
+`assertNotIn`. It is deliberately **not** a ban on the phrase: both files use
+"byte-for-byte" correctly about other things — a row inside an HTML comment IS
+byte-for-byte a genuine row; `perry-tasks risks-diff` DOES byte-compare — and a
+guard that reddened those is a guard the next person to hit it deletes. Both
+halves are pinned by mutation: **M38** (put the overclaim back in
+`bin/README.md`) and **M39** (delete the correcting sentence there).
+
+### 1.1 · The V4 FAIL — the refusal was a wall, and now it is not
+
+Round 1's refusal said *"diff it against the record and remove what does not
+belong: `perry-conform status`"*. The reviewer measured what `status` actually
+does: **it computes no diff, reports nothing about the markdown's contents, and
+names `perry-conform migrate`** — the command that had just refused. No shipped
+surface named the offending line; `status`, `check`, `migrate`, `declare` and
+`perry-lint` were all checked, in text and `--json`.
+
+And on such a project **every write path is closed**: `declare` calls
+`migrate_record` first and raises, `perry-migrate apply` refuses and rolls back,
+and all three gate call sites refuse because no store exists. So round 1's claim
+— *"the cost of refusing is look at your file"* — was **false**. The measured
+cost was: read 37 lines by eye, with no tool help, while nothing can write. It is
+reachable by ordinary editing (7 of 9 plausible hand edits refuse), and it
+contradicted a standard written in the same file, `bin/perry-conform § message_for`:
+
+> *a gate that says "not conformant" and stops is a wall — every branch here
+> ends in a command the reader can run.*
+
+**The fix.** `render_legacy(...)` was already computed on the refusing line;
+`record_diff()` turns it into a unified hunk with a legend for the direction
+(`-` is your file, `+` is what Perry reads out of it, so a `-` line alone is a
+line to delete and a `+` line is one to restore), capped at `DIFF_CAP = 40` so a
+wholly-rewritten record cannot bury the message's own last sentence. What it
+prints, on the shape that motivated the fixed point:
+

+```
+
+`TestTheRefusalNamesTheLine` measures it on all four plausible hand edits the
+reviewer named — a trailing blank line, a note under the table, rows re-ordered
+by hand, a row hidden in an HTML comment — one subTest each, plus **two
+controls**: the canonical record still converts, and *deleting a row still
+withdraws a declaration*, which is the edit the file's own header invites and
+must never refuse.
+
+**Why it shipped, which is the more useful finding.** `assert_conversion_refuses`
+— the helper **14 test methods route through, at 16 invocations** (one method,
+`test_a_canonical_row_inside_an_html_block_is_not_carried_across`, calls it
+three times under `subTest`) — asserted only `"refused" in out`. Any
+refusal at all passed it.
+
+> **The number was wrong in round 3 and is corrected here.** This said "17",
+> which is § 4.3's count of *moved* tests — a different set — carried into a

+> again in round 4 (`scratchpad` harness, 18 tests in the class, all green).
+> **14 methods, 16 invocations.** Corrected in both places it appeared, here
+> and in § 11. It now requires the refusal to **locate** the problem
+(a line number from the unreadable-rows branch, or a diff from the fixed-point
+branch), to name a runnable command, **never** to name `perry-conform status`,
+and — where the caller knows it — to quote the exact offending line, because a
+diff of the *wrong* lines passes every other assertion in the helper.
+
+> **"A runnable command" was a substring test until round 5.** The helper
+> checked `assertIn(f"--root {root}", cmd)`, which is satisfied by
+> `--root /home/ada/My Project` — a line that parses as five arguments. It
+> `shlex.split`s the phrase now and compares the parsed root, so "runnable" is
+> a property of the command rather than of the text (§ 1.3). The helper and its
+> extractor moved to `tests/handed_back.py`, which `tests/test_migrate.py` uses
+> too: that module held a second, hand-written spelling of the same rule, and
+> the second copy is the one that went stale.
+
+**The helper is weaker than that sentence sounds, and round 3's write-up did
+not say so.** Of the 16 invocations, only **4** reach the fixed-point refusal
+the FAIL was about — the three HTML spellings and the hand-edited header. The
+other **12** take the unreadable-rows branch and satisfy "locates the problem"
+through the `line N:` it printed all along. So the diff-related teeth bite at 4
+sites, not 16. Measured both ways: at runtime (12 / 4, round 4), and by
+mutation — injecting `perry-conform status` into the fixed-point refusal
+reddens exactly 4, and blanking `line {n}: {t}` reddens exactly 12.
+
+**Measured consequence of the fixed point**, found by the fixture: a record whose
+rows a hand has re-ordered refuses, because the writer sorted by path. Any record
+`perry-conform declare` wrote is sorted, so this bites a hand-edited file only —
+which is exactly the file the check exists for, and the diff now names the moved
+row.
+
+### 1.2 · The round-3 V4 FAIL — the refusal named a command with the root dropped
+
+**The defect.** `bin/perry-conform § message_for` propagates the invocation's
+`--root` into every branch through `_root_flag()`. `migrate_record`'s two
+refusals — including the one round 3 rewrote **under the wall standard's own
+banner** — did not. Measured end to end by the reviewer on a planted project:
+
+```
+$ python3 bin/perry-conform migrate --root $PROJ     # the reader is routed here
+… Fix those lines, then run:
+    perry-conform migrate                            # ← the root is gone
+$ python3 bin/perry-conform migrate                  # the reader copies it
+perry-conform: nothing to convert — .perry/conformance.jsonl is already this
+project's record (or it has none).
+rc=0
+```
+
+**Exit 0, a success-shaped sentence, about a project the reader never asked
+about** — while their own record sits unconverted and still gating every write.
+The row's own rule is *"a named command that errors is worse than none"*; this
+is the worse-still variant, because nothing tells the reader anything happened.
+
+**The fix.** `root_arg` is threaded into `migrate_record` and `declare` as a
+**keyword-only parameter with no default**, so a caller that has a root must
+pass it and a new caller cannot inherit the omission by saying nothing.
+`bin/perry-migrate § apply_plan` passes its own, because `declare` converts the
+record first and that step can refuse.
+
+**The sweep — this is a class, and here is how many members it has.** Mechanical,
+off the AST rather than by grepping text, so a docstring discussing the defect
+is not a finding. A `perry-*` phrase in a non-docstring string literal is
+*handed back* when it is introduced the way this codebase introduces a command
+to copy — at the start of an indented continuation line, or immediately after
+`run` / `with` / `is` / `try` / `use` — and it passes only if `{r}`,
+`{_root_flag(...)}` or a literal `--root` travels inside the phrase. Prose that
+merely names a tool is not an instruction and is not counted: *"is not what
+`perry-conform declare` would have written"* names a command the reader is being
+told **not** to run.
+
+Round 5 adds the second ruling — **`unquoted {expr}`**, § 1.3 — so the table
+below is the whole class under one rule, measured with the round-5 sweep over
+all three trees rather than with each round's own:
+
+| tree | handed back | without the caller's root | interpolating a value raw |
+|---|---|---|---|
+| `7d3f93f` (round-3 tip), both tools | 23 | **7** | **8** |
+| `f783dd5` (round-4 tip), both tools | 22 | **3** | **7** |
+| round-5 tip, both tools | 21 | **0** | **0** |
+| the rest of `perry-conform`'s runtime import closure — `bin/perry-lint`, `viewer/parsers.py`, `viewer/tables.py`, `bin/perry_store.py`, `bin/perry_md_store.py`, `bin/lib/__init__.py` | 0 | 0 | 0 |
+
+The command that produced every row, run from the repository root — the
+`before` files come from `git show <rev>:<path>`:
+
+```
+python3 tests/sweep_handed_back_commands.py --all \
+    bin/perry-conform bin/perry-lint bin/perry_md_store.py bin/perry_store.py \
+    viewer/parsers.py viewer/tables.py bin/lib/__init__.py bin/perry-migrate
+```
+
+It exits 1 while any member remains and today it exits 0. **Both tools are in
+the suite guard now**, not `bin/perry-conform` alone:
+`test_no_refusal_in_perry_conform_names_a_command_without_the_root` **imports
+this same module** rather than restating the rule — a second copy would be a
+second definition, and the first to go stale would be the one nobody ran — and
+asserts both that the finding list is empty and that the sweep found at least
+20 commands, so an empty list cannot come from the sweep having stopped
+working.
+
+> **The counts moved for a reason and it is not that commands appeared and
+> vanished.** 23 → 22 → 21 is the `{tail}` that used to be glued to the DRIFTED
+> branch's command (§ 1.3) coming off, plus `IS_WHOLLY_A_COMMAND` reading a
+> handful of literals differently. The numbers to compare across rows are the
+> two right-hand columns.
+
+**This is a lower bound, not a census, and that has to be said wherever the
+number is quoted.** What the rule cannot see it does not count. Round 5
+measures the size of that blind spot instead of asserting there is one:
+`tests/fixtures/handed_back_spellings.py` plants one defect per plausible
+spelling and `TestTheSweepIsMeasuredNotTrusted` recomputes the rate every run.
+**18 of 19 found**, and **14 of the 15** the V4 round-4 reviewer planted — where
+the round-4 sweep scored **10 of 15**. The four it gained are one shape: a
+command reaching the message through a NAME (module constant, local, dict
+value, helper return), which `IS_WHOLLY_A_COMMAND` reads because a string that
+is nothing but a command has no sentence around it to carry a cue word. The one
+residual is a cue word outside the list, and the fixture says why adding cue
+words does not close it.

+    EOF
+
+**Where the rule under-counts, said out loud rather than left to be found.**
+The ruling is made from the words immediately before the phrase, so
+`bin/perry-lint`'s fix hints — which read *"`perry-tasks render --write` puts
+the file back in line"* rather than *"run `perry-tasks render --write`"* — are
+read as mentions. Under a deliberately crude rule (**any** backticked or
+indented command in a runtime message) `bin/perry-lint` has **22** handed-back
+commands and **all 22** drop the root. That is a real, pre-existing class in a
+tool this row does not own; it reaches a `perry-conform` reader only as
+`findings[].fix` strings inside `--json`; and closing it means threading a root
+through check functions that never had one. **Measured and recorded, not fixed
+here** (§ 10.10). Under the same crude rule `bin/perry-conform` has 5, and all 5
+are prose rather than instructions — `perry-state` three times in *"`perry-task
+list` and `perry-state` work either way"*, the legacy header's *"Written by
+`perry-conform declare`"*, and *"is not what `perry-conform declare` would have
+written"*, which names the one command the reader is being told **not** to run.
+
+**The proof is end to end and constructs no expected string.**
+`test_the_named_command_converts_the_readers_project_from_elsewhere` plants two
+real projects — the reader's, and a *different* one, already converted, that the
+reader is standing in. It **measures the harm** (the bare command exits 0 with
+"nothing to convert" and leaves the reader's record untouched), then takes the
+command **out of the refusal text**, runs it unedited from the other project's
+directory, and asserts the reader's project converted with its date intact and
+the other came back byte-identical. A test that built the expected string by
+hand would pass on the broken implementation; this one runs whatever the message
+says, which is why mutation **M34** — naming a root that is not the caller's —
+reddens it while every string assertion in the suite stays satisfiable.
+
+**Why no test caught it.** All 16 helper invocations asserted this message
+*while themselves running with `--root <tmpdir>`*.
+`assertIn("perry-conform migrate", message)` is true of the broken string and is
+not about the reader's situation in that test. **The assertion checked that A
+command was named, never that it was the command the caller could run.** The
+helper now extracts every command the refusal hands back and requires each to
+carry `--root <the root this caller used>` — generic, so a refusal that grows a
+new command tomorrow is caught by the same assertion. Non-vacuity measured at
+every one of the 16: a command was extracted at all 16, the shortest message is
+536 characters, and mutation **M32** (compute the flag from `None`) reddens all
+16 at once.
+
+### 1.3 · The round-4 V4 FAIL — the root was there and the line was not a command
+
+**The defect.** `_root_flag` built ` --root {root_arg}` by raw interpolation.
+`shlex.quote` appeared nowhere in `bin/` or `viewer/` — checked, not assumed.
+So on a project at `.../My Project` the refusal § 1.2 had just fixed handed the
+reader:
+
+```
+Fix those lines, then run:
+    perry-conform migrate --root /…/r4space/My Project
+```
+
+and copying that line, verbatim, from where they were standing:
+
+```
+perry-conform: refused — usage: perry-conform migrate — it takes no file. …
+rc=1
+```
+
+`Project` was parsed as a file argument. The record stayed unconverted and the
+error was about a mistake the reader did not make. **The same sentence, the
+same standard, found the same way — by running the command the refusal hands
+back.** § 1.2's own rule names it: *a named command that errors is worse than
+none*.
+
+It is strictly less harmful than § 1.2's defect — it fails loudly instead of
+succeeding about someone else's project — and that is not the point. The point
+is that this is the third round in which the fix to a handed-back command
+produced a new handed-back command that does not work.
+
+**The fix is one line, and the fix is not the work.**
+
+```python
+def _q(value) -> str:
+    return shlex.quote(str(value))
+
+def _root_flag(root_arg: str | None) -> str:
+    return f" --root {_q(root_arg)}" if root_arg else ""
+```
+
+#### Why this shape cannot be routed around the way `_root_flag` was
+
+`_root_flag` was already the single choke point for the root. It did not fail
+because it was the wrong shape; it failed because **a choke point is a
+convention, and a convention is enforced by whoever remembers it.** Round 3
+forgot to call it. Round 4 called it and wrote the interpolation wrong inside
+it. Putting `shlex.quote` in the same two lines and stopping there would leave
+round 6 free to write `--root {root_arg}` at the next site, exactly as round 3
+wrote `perry-conform migrate` at that site.
+
+So the shape is the choke point **plus a rule that makes the bypass spelling
+red**, and it is the second half that is new:
+
+1. **`_q` is the one place an argument is quoted**, and `_root_flag` is built
+   out of it. Every other argument of every handed-back command in both tools
+   goes through it too — four `{v.path}` sites in `bin/perry-conform`
+   (`perry-conform check 'My Notes.md'` is a file a reader can really have and
+   was handed back raw), and `{point.stem}` / `{applied['run']}` in
+   `bin/perry-migrate`.
+2. **`tests/sweep_handed_back_commands.py` reads every handed-back command off
+   the AST and reports any `{...}` inside one that is not `_q(...)`,
+   `_root_flag(...)`, `shlex.quote(...)`, or the `r` those produce.** The
+   sanctioned set is closed and tiny on purpose.
+3. **A separate rule, `FLAG_VALUE`, reads a long flag's value in *any*
+   template, command phrase or not** — because `_root_flag`'s own body names no
+   tool, so no command-phrase rule can reach the place round 4's defect
+   actually lived. This is the rule that would have caught it.
+4. **`test_no_refusal_in_perry_conform_names_a_command_without_the_root` runs
+   that sweep over both tools** and fails the suite on either ruling.
+
+Measured, not argued: mutation **M42** puts round 4's defect back in
+`_root_flag` and the source guard goes red; **M43** un-quotes one `{v.path}`
+and it goes red; **M44** re-glues the `{tail}` below and it goes red. All three
+are red on the source guard **and nothing else** — see § 6.1.
+
+#### A second member, found by the new rule and not by anyone reading the branch
+
+`message_for`'s DRIFTED branch is the only one whose last line IS the command,
+and it appended the unreadable-lines parenthetical to it:
+
+```
+    perry-conform declare BOARD.md --root '/…/My Project' (2 line(s) in
+    .perry/conformance.jsonl could not be read and were not counted as
+    declarations)
+```
+
+Pasted into `/bin/sh`: `syntax error near unexpected token '('`, **rc=2**.
+Parsed with `shlex.split`: the command plus eighteen junk arguments. Measured
+both ways. `{tail}` now goes on a line of its own.
+
+#### The proof stops only ever seeing friendly input
+
+**The row's own end-to-end proof already ran `shlex.split` on the handed-back
+command — the exact parser that exposes this — and was green**, because
+`tempfile.TemporaryDirectory()` never yields a path with a space in it. One
+character in a fixture was the difference between a proof and a ritual.
+
+Every fixture project in `tests/test_conformance.py` and `tests/test_migrate.py`
+is now built under a directory named:
+
+```
+My Project (v2) & 'draft' "q" $x; echo hi #1 *
+```
+
+— word splitting, the four metacharacters that turn a paste into a syntax error
+or a backgrounded fragment, both quote characters, parameter expansion, a
+comment marker and a glob. **19 tests went red on that change alone.** Two
+characters are deliberately absent and both are recorded as limitations rather
+than oversights: a newline (a root containing one cannot be handed back on a
+single line at all) and a backtick (§ 10.12).
+
+And the proof now runs the command through **`/bin/sh -c`**, not only through
+`subprocess` with a split argv. `shlex.split` proves the line parses; it does
+not glob, expand `$`, or substitute — and the fixture root ends in `*`. Only
+the tool's own name is substituted; the rest of the line is passed
+byte-for-byte, so the quoting under test is the quoting that runs.
+
+The whole thing, on a planted throwaway project, copied into a real shell:
+
+```
+$ cd .../r5space/elsewhere
+$ python3 bin/perry-conform migrate --root ".../r5space/My Project (v2) & 'draft'"
+    …
+Fix those lines, then run:
+    perry-conform migrate --root '/…/r5space/My Project (v2) & '"'"'draft'"'"''
+**Nothing was written.**
+
+  # the reader fixes those lines and pastes that line, unedited
+  ✓ carried 1 declaration(s) from .perry/conformance.md into
+    .perry/conformance.jsonl, dates and routes unchanged
+  ✓ deleted .perry/conformance.md
+rc=0
+```
+
+The reader's record converted with its 2026-08-20 date intact; the project they
+were standing in was untouched.
+
+#### The assertion that could not see it
+
+`assert_every_command_carries` read `assertIn(f"--root {root}", cmd)` — the
+assertion written in round 4 to catch round 3's defect. A substring test is
+satisfied by `--root /home/ada/My Project`. It **parses** now:
+`shlex.split(cmd)`, then exactly one `--root`, then its value equal to the
+caller's root. A phrase that does not survive `shlex.split` is not a command,
+whatever it looks like.
+
+The extractor and the assertion moved to **`tests/handed_back.py`**, because
+`tests/test_migrate.py` held a second, hand-written spelling of the same rule
+(`assertIn(f"perry-migrate restore {run_id} --root {p.root}")`) and the second
+copy is the one that went stale. Moving them surfaced a disagreement neither
+file could see: `commands_named` required **four** spaces of indentation and
+the source sweep's `CUE` required **two**, so `bin/perry-migrate § do_restore`
+prints its listing's command under three spaces — a handed-back command to one
+rule and invisible to the other. `test_every_way_back_this_tool_names_carries
+_the_root` was asserting over an empty extraction. Both are `[ ]{2,}` now, and
+mutation **M56** puts the disagreement back and reddens that test.
+
+`test_the_declare_command_the_refusal_names_is_runnable_verbatim` was also not
+running it verbatim: it split the line on whitespace and then appended a
+`--root` of its own, discarding whatever the message named. Both halves fixed.
+
+## 2 · Self-reference — moved across explicitly, and split into two questions
+
+`schema/state-schema.json:2053` said, of the markdown:
+
+> *deliberately NOT a `files[]` entry: it is a record of the user's decisions
+> ABOUT state, not state, and listing it here would make it declarable-conformant
+> about itself.*
+
+**`files[]` — unchanged, restated, and now tested.** The note now names
+`.perry/conformance.jsonl`, says the reasoning survived the format change
+unchanged and is restated rather than carried silently, and adds what the row
+discovered: the exclusion is *what makes the conversion possible at all*.
+`TestTheRecordIsNotDeclarableAboutItself.test_the_record_is_not_a_files_entry`
+asserts it for **both** names, so re-adding either goes red.
+
+**`claims[]` — a separate question with its own answer.** The spec says *"whether
+`conformance.jsonl` joins `claims[]` at all is the same question as (2)"*. It is
+not. `files[]` decides shape validation and therefore self-declarability;
+`claims[]` decides namespace collision in someone else's project. Listing the
+record in `claims[]` would not make it declarable-conformant about itself.
+
+**Decision: no `claims[]` entry of its own.** Three reasons, in order of weight:
+
+1. **It is already covered.** `.perry/` is a `claims[]` dir entry. The existing
+   `test_the_record_is_not_reported_as_someone_elses_file` measures 0 collisions
+   with the record present, and it passes **unchanged** on the store — the record
+   moved and the collision answer did not.
+2. **The precedent is naming, not coverage.** `.perry/events.jsonl` and
+   `.perry/config.jsonl` are listed individually, and `tests/test_claims.py §
+   test_perry_dir_is_the_only_project_anchored_territory` reads that as *"it adds
+   no second immovable place, it names a file in the immovable one"*. A seventh
+   entry would add nothing `perry-lint --claims` can see.
+3. **It would move a denominator that is not this row's to move.**
+   `perry/phase/003-linkage.md`'s `P003-O1-KR1/2/3` are each phrased *"6 of 6"*
+   over the stores in `claims[]`. Adding one makes three KRs wrong.
+
+Reason 3 is now a **tripwire**, not a paragraph:
+`test_the_record_is_not_a_claim_of_its_own_and_does_not_need_one` counts the
+claimed `.jsonl` stores (excluding the event log) and fails naming the three KRs
+if the number leaves 6. So the goals lane is told by a red test, not by memory.
+
+## 3 · The store
+
+```json
+{"kind": "declaration", "path": "BOARD.md", "shape_version": 2,
+ "declared": "2026-08-20", "route": "declare",
+ "writer": "perry-conform declare",
+ "recorded_at": "2026-08-30T09:12:03+08:00", "run": ""}
+```
+
+`writer` / `recorded_at` / `run` are the provenance. `route` already said *how* a
+declaration was made; these say **who**, **when to the second** (`declared` is a
+day), and **which migration run** — and the run id is also the name of the
+restore point under `.perry/migrate/`, so a migrated row can be traced to the
+bytes it replaced. `tests/test_migrate.py § test_the_declaration_goes_through_
+perry_conform_and_is_the_only_record` asserts the run a declaration names is a
+restore point that exists on disk. This is the point of the conversion: TASK-226
+was an investigation rather than a query because a row could answer none of the
+three.
+
+**Provenance is empty on every converted row, deliberately.** The markdown never
+held it, and stamping the conversion's own clock onto a decision made on
+2026-08-20 would put a fact in the record that nobody recorded
+(`test_the_conversion_invents_no_provenance`).
+
+**Reading is per line, not all-or-nothing.** A malformed line is `unreadable` and
+voids nothing around it. This is TASK-241 round 2's measurement carried across
+the format change: under a whole-file rule one stray line voids all 23 of Perry's
+declarations. A **duplicate `path`** is unreadable rather than last-one-wins —
+two lines claiming one file disagree about when it was declared, and picking one
+would make the record's answer depend on line order.
+
+**A markdown found beside a store** is reported as `stray_legacy` and **not
+read**, and `perry-conform status` says so — a user editing it would be editing
+nothing and would otherwise have no way to find out.
+
+## 4 · The 69 tests of `tests/test_conformance.py` — verdict, one by one
+
+**None deleted. 69 → 91 (+22 added, 0 removed).** No test lost its subject; the
+markdown reader is still shipped and still reads a pre-conversion record exactly
+once, so § 10b's subject *moved* rather than disappeared.

+
+Every test in § 1 (partly), § 2 (partly), § 4, § 5, § 6, § 7, § 8, § 9 (partly),

+
+The property is identical; the assertion named a markdown row. Each still
+hand-edits the record, because a hand edit is what each is about.
+
+| Test | What changed |

+| `test_the_shape_version_is_the_schema_version_and_not_a_second_number` | reads `shape_version` off the record instead of the row text |
+| `test_a_declaration_at_an_older_shape_version_is_never_silently_accepted` | plants `"shape_version": 1` instead of rewriting the version cell |
+| `test_the_declared_version_is_readable_without_re_deriving_it` | same |
+| `test_a_row_that_cannot_be_read_is_reported_not_treated_as_absent` | plants `"shape_version": "v-two"` — a string where a number belongs — instead of `\| v-two \|` |

+| `test_the_record_survives_a_second_declaration` | two row-substring assertions → two key assertions |

+### 4.3 · Subject MOVED to the one-way door, kept and strengthened — 17
+
+> **This 17 is a count of MOVED tests and is a different set from the
+> number of tests that route through `assert_conversion_refuses`** (14
+> methods, 16 invocations — § 1.1). Round 3 carried this number into a
+> sentence about routing, where it was false.
+
+Every § 10b test. Each keeps its planted shape and its own control, and each
+gained a **second, independent** assertion. The two layers can go red alone:
+
+- **layer 1 — the reader still refuses the row.** TASK-241's round trip and fence
+  rule, measured on `read_legacy_conformance`, which is the same function.
+- **layer 2 — the conversion refuses the file.** Exit code, the store not
+  written, the markdown not deleted, and `BOARD.md` still `undeclared`.
+
+`test_an_asterisked_path_reads_exactly_as_it_did_before` is what proves layer 2
+is **not** a substitute for layer 1: that row *is* a file-level fixed point, so
+only the round trip stands between a decorated row and a real key. And mutation
+**M20** (delete the round trip) reddens
+`test_a_backticked_path_cell_is_not_a_declaration` while the fixed point is
+intact — measured, not argued.
+
+`test_a_backticked_path_cell_is_not_a_declaration`,
+`test_an_indented_row_is_not_a_declaration`,

+`test_a_path_cell_that_cannot_be_written_back_is_reported_not_crashed` (still
+`U+2028`; the `perry-conform status` no-traceback assertion is kept and the

+`test_a_bolded_header_row_is_still_not_a_row` (TASK-050's `squash` rule; the
+conversion also refuses it, and the two reasons are asserted separately so
+neither hides the other),
+`test_perrys_own_record_is_read_without_a_single_refusal`.
+
+**Two of these changed their expected outcome and that is stated rather than
+buried.** `test_a_nested_fence_row_is_not_laundered_by_the_next_declare` and
+`test_a_planted_row_is_not_laundered_by_the_next_declare` used to assert the
+declare *succeeded* on a different file and did not launder the planted row. It
+now **refuses** — a project whose markdown record is not convertible cannot
+declare anything until the record is fixed. That is strictly fail-closed and it
+is a behaviour change; it is asserted, including that the other file is *not*
+half-declared on top of a record that was not converted.
+
+### 4.4 · Moot — 0
+
+None. Every one of the 69 still measures something. The closest to moot is
+`test_a_bolded_header_row_is_still_not_a_row`, whose *record* has no header any
+more — but its subject, TASK-050's fifth `squash` copy, is still live in the
+markdown reader and is still what stands between a bolded header and a laundered
+declaration at the door.
+
+### 4.5 · One test elsewhere went VACUOUS and was caught
+
+`tests/test_one_header_rule.py § TestTheFifthCopy` probes through
+`P.read_conformance`. After the conversion every probe returned `([], [])` and
+`test_decoration_on_the_header_changes_nothing` compared nothing to nothing — it
+was **green for the wrong reason**. Repointed at `read_legacy_conformance`, and
+given an assertion that the plain case is non-empty so it cannot go vacuous
+again. Found by reading the module, not by the suite.
+
+## 5 · TASK-246 and TASK-248 — confirmed, not assumed
+
+### TASK-248 — **DISSOLVED**
+
+*A canonical row inside `<pre>`, an HTML comment or `<details>` still declares
+and is still laundered.*
+
+- **The declaring half is gone.** The record is a JSON object per line. There is
+  no "inside" for a row to hide in, no HTML block, no fence, no decoration. This
+  is structural, which is what the row's own `next_action` asked for.
+- **The laundering half is gone.** The markdown writer no longer exists —
+  `render()` was deleted and `render_legacy()` writes nothing; it is only the
+  right-hand side of a comparison. Nothing can be laundered into a canonical
+  markdown row because nothing writes one.
+- **The one place it could have survived is the conversion, and it is closed
+  there too.** I measured the shape live rather than assuming:
+  `test_a_canonical_row_inside_an_html_block_is_not_carried_across` asserts, for
+  `<pre>`, an HTML comment and `<details>` separately, that the reader **does**
+  honour the row (so the test measures the real shape) and that the conversion
+  refuses the file anyway. Mutation **M9** — delete the fixed point — reddens it.
+- **Verdict: dissolved.** Not mine to close on the board.
+
+### TASK-246 — **NOT dissolved. It survives the format change.**
+
+*An unreadable row is deleted by the next `declare` rather than reported.*
+
+I expected this one to die and it does not. Measured:
+
+- The writer still rebuilds the whole record from the parsed declarations,
+  exactly as the markdown writer did. A line it could not read is **not carried
+  forward** — it is gone from the file, with no report at the moment of
+  destruction. Identical mechanism, identical harm.
+- What the conversion changes is the **population**, not the mechanism. Under
+  markdown, a row became unreadable through decoration a person would plausibly
+  type — the header invited hand editing, and backticks, indentation and fences
+  are ordinary markdown. Under jsonl a line is unreadable only if it is not valid
+  JSON or has a wrong-typed field. Rarer; the file still says *delete a line to
+  withdraw a declaration*, so hand editing is still invited.
+- Pinned **as it is**:
+  `TestWhatTheConversionDoesNotDissolve.test_an_unreadable_line_is_still_dropped_
+  by_the_next_declare`. The day TASK-246 is fixed, that test goes red and is
+  rewritten deliberately, instead of the project believing a row died when it
+  did not.
+- **One place the class IS closed**, and it is the dangerous one: the
+  *conversion* refuses rather than drops
+  (`test_an_unreadable_row_is_refused_rather_than_deleted_at_the_door`,
+  mutation **M10**). A one-way door that destroys a line the user typed is not
+  something to leave for a follow-up row.

+
+> **"29/29" was, until round 4, one run that nobody had reproduced.** The V4
+> round-3 reviewer re-ran **8** of the 29 (M22-M29) plus M15's branch as a
+> control, added 9 of its own, and said plainly that M1-M14 and M16-M21 were
+> **not** re-run. Round 4 re-ran the whole harness and extended it to 40. Round
+> 5 re-ran it whole again, in a private detached worktree, and extended it to
+> **57 — all red** (§ 7.1 for the run). Seventeen are new: M41-M44 for the

+Harness: `tests/mutate_task_234.py`. Uniquely named; **refuses a dirty tree**;
+anchors on exact text and asserts the anchor is **unique** in the file; resolves
+the line number at run time; clears every `__pycache__` and sleeps to a whole
+second before and after each write; asserts the named test is **GREEN** before
+mutating; restores by `md5` and asserts the digest.

+### 6.1 · Round 4 — M30-M40, and the two that came back GREEN
+
+| # | File | Mutation | Named test that went red |
+|---|---|---|---|
+| M30 | `bin/perry-conform` | the fixed-point refusal drops `{r}` — **the shipped defect, put back** | `…test_the_named_command_converts_the_readers_project_from_elsewhere` |
+| M31 | `bin/perry-conform` | the unreadable-rows refusal drops `{r}` | `…test_the_unreadable_rows_refusal_names_it_too` |
+| M32 | `bin/perry-conform` | `_root_flag(root_arg)` → `_root_flag(None)` — the runtime value, which the source guard cannot see | `TestADecoratedRowIsNotADeclaration.test_a_backticked_path_cell_is_not_a_declaration` (and all 16 helper invocations with it) |
+| M33 | `bin/perry-conform` | `declare` stops passing the root into the conversion | `…test_the_declare_route_into_the_conversion_carries_the_root_too` |
+| M34 | `bin/perry-conform` | the refusal names `--root /nowhere-at-all` — **spelled correctly, wrong project** | `…test_the_named_command_converts_the_readers_project_from_elsewhere` |
+| M35 | `bin/perry-migrate` | `apply_plan` stops carrying its root into `C.declare` | `tests.test_migrate … test_an_unconvertible_markdown_record_refuses_and_names_the_way_back` |
+| M36 | `bin/perry-migrate` | `rollback_message` drops the root from `perry-migrate restore <id>` | same |
+| M37 | `bin/perry-migrate` | the restore-point listing drops it | `tests.test_migrate … test_every_way_back_this_tool_names_carries_the_root` |
+| M38 | `bin/README.md` | put the overclaim back — "not **byte-for-byte** what `perry-conform declare` would have written" | `…test_a_crlf_record_converts_and_the_wording_does_not_say_byte` |
+| M39 | `bin/README.md` | delete the sentence that states the difference | same |
+| M40 | `bin/perry-conform` | M30's mutation, named against the SOURCE guard rather than the end-to-end proof | `…test_no_refusal_in_perry_conform_names_a_command_without_the_root` |
+
+**The three-layer argument, rewritten to match what is measured.** The
+paragraph that stood here said *"M40 is caught only by reading the source …
+M34 is invisible to both … Three layers, one per failure mode, each
+demonstrated by the mutation the other two miss."* The V4 round-4 reviewer
+measured it and **two of those three claims are false**: M34 reddens the
+helper — `assert_every_command_carries` asserts the *exact* root, so a
+correctly-spelled wrong root reddens every helper invocation reaching the
+fixed-point branch — and **M40 is byte-for-byte the same mutation as M30**
+(same anchor, same replacement; verified by comparing the two harness entries),
+so "caught only by reading the source" cannot be true of either.
+
+Re-measured at the round-5 tip, whole of `tests.test_conformance` +
+`tests.test_migrate`, distinct failing methods in brackets, and which of the
+three layers went red:
+
+| mutation | failures | methods | source guard | helper | end-to-end |
+|---|---|---|---|---|---|
+| M30 / M40 — `{r}` deleted from the fixed-point template | 8 | 6 | **yes** | yes (4) | yes |
+| M34 — `--root /nowhere-at-all`, spelled correctly | 7 | 5 | no | yes (4) | yes |
+| M32 — `_root_flag(None)`, the runtime value | 20 | 18 | no | yes (16) | yes |
+| M41 — `_q` stops quoting | 25 | 23 | no | yes (16) | yes |
+| M42 — `_root_flag` interpolates the root raw | 26 | 24 | **yes** | yes (16) | yes |
+| M44 — `{tail}` re-glued to the DRIFTED command | 1 | 1 | **yes** | no | no |
+| M52 — `perry-tasks render --write` drops the root | 1 | 1 | **yes** | no | no |
+| M53 — `perry-goals commit --migrate` drops the root | 1 | 1 | **yes** | no | no |
+
+**No mutation of that line is caught by exactly one layer, and the argument
+that said so was wrong.** What the measurement supports instead is narrower and
+stands on its own:
+
+* **The source guard is the only layer that can see a site no test exercises.**
+  M44, M52 and M53 redden it and **nothing else in either module** — one
+  failure, one method, each. All three are real defects in messages no fixture
+  reaches: the DRIFTED branch's parenthetical, and the two `bin/perry-migrate`
+  refusals `§ 10.9` used to excuse. That is the source guard earning its keep,
+  measured, rather than being the layer that happens to catch what the others
+  do too.
+* **The helper is the only layer with breadth, and the source guard is blind to
+  what it sees.** M32 and M41 leave the template correct and the runtime value
+  wrong; the source guard stays green and 16 helper invocations plus the
+  end-to-end proof go red together.
+* **The end-to-end proof is the only layer that RUNS the command**, which is
+  what found § 1.3's FAIL in the first place — by a reviewer, not by the suite,
+  because the fixture roots had no spaces. What it uniquely covers now is
+  shell-level behaviour that `shlex.split` does not perform: globbing, `$`
+  expansion, substitution. I did not construct a mutation caught by *only* that
+  layer, and say so rather than claim one.
+
+**M34's 7 / 5 and M32's 20 / 18 are the reviewer's own figures reproduced at a
+different tip**, which is also an independent confirmation of § 1.1's corrected
+**14 methods / 16 invocations** and its 4 / 12 split: M34 mutates only the
+fixed-point branch and produces exactly 4 helper failures.
+
+**M35 came back GREEN, and that is the finding.** `perry-migrate apply --root
+X` is the other way into `migrate_record`'s refusal, and no test held it: with
+`root_arg=None` there, the whole of `tests.test_migrate` **and** the whole of
+`tests.test_conformance` stayed green. Closed by requiring both commands in that
+message — this tool's `perry-migrate restore <id>` and the quoted
+`perry-conform migrate` — to carry the reader's root.
+
+**M36 came back GREEN too, pointed at the wrong test, and the reason is worth
+recording.** `perry-migrate restore <id>` is named on **two different code
+paths**: `render`, under a finished run, and `rollback_message`, under a failed
+one. The first test written for it read the successful path only, so mutating
+the *failure* path changed nothing it could see. Re-pointed at
+`test_an_unconvertible_markdown_record_refuses_and_names_the_way_back`, which is
+the test that makes a run fail; red there. Two surfaces naming one command are
+two guards, not one.
+
+**M23 and M24 are two more defects, and both are the FAIL's own shape.**
+`max(0, len(lines) - DIFF_CAP)` reads as belt-and-braces and is load-bearing:
+without it `dropped` is negative for every diff shorter than the cap, `if
+dropped:` is true for a negative number, and **every ordinary refusal would have
+ended "… and -37 more diff line(s)"** — a false statement on the one message the
+FAIL was about. And M24 caught the cap test asserting that the notice *exists*
+while never checking the *number*, so replacing the count with a constant stayed
+green. Both are an assertion sitting beside the thing that matters, which is
+what `assert_conversion_refuses` was doing too.
+
+**M21 is a defect this row introduced, found by reading the handler.**
+`apply_plan`'s `except (OSError, Refused, ValueError)` around the declaration
+uses `bin/perry-migrate`'s own `Refused`. `declare()` gained a step that can
+refuse — the record conversion — so `bin/perry-conform`'s refusal is a different
+class and walked straight past it: fully migrated, restore point on disk and
+**never named**, raw traceback. That is Site 3's own documented failure mode,
+verbatim, made reachable by this row. Fixed, tested
+(`test_an_unconvertible_markdown_record_refuses_and_names_the_way_back`, which
+asserts the refusal names `perry-migrate restore` and that stderr carries no
+`Traceback`), and pinned.
+
+**M11 found a real hole and it is the reason to run these.** The first pass had
+no test that called `migrate` on a project holding *both* records. With the guard
+weakened, a markdown restored from a backup beside a live store was converted
+over the top of it — every declaration rolled back to whatever the markdown said,
+and the markdown deleted. Found by mutation, not by review. Test added; the run
+above is the re-run.
+
+Two other findings from the harness itself: **M18**'s named test was in the wrong
+class (the harness said `ALREADY RED`, which is the failure mode it exists to
+catch), and **M9/M20** together are what let § 4.3 claim the two layers are
+independent rather than asserting it.
+
+### 6.2 · Round 5 — the four the V4 round-4 reviewer found GREEN, and why each was
+
+All four were green for one reason with three faces: **an assertion was being
+made from inside a run the reader never has.** That is the round-3 defect's own
+sentence, and the reason it kept recurring is that each round closed the
+instance and left the shape.
+
+**R-N3 and R-N4 — two of `rollback_message`'s three call sites could drop the
+caller's root with both modules green.** These are TASK-044 guarantee 3's own
+paths: a write that fails (read-only directory, full disk, permission revoked
+mid-run) and a write that lands with the wrong digest. Both hand the reader
+`perry-migrate restore <run-id>` as the way back.
+
+Green because every test that reached them called `M.apply_plan(plan, SCHEMA)`
+positionally, so `root_arg` was `None` on both sides of the mutation and
+`_root_flag` returned `""` either way. **Why the round-3 fix did not reach
+here**, which the round-4 reviewer asked and this document owes an answer to:
+round 4 gave `bin/perry-conform`'s two entry points a keyword-only parameter
+with no default and *argued for that shape in this file*, and then gave
+`bin/perry-migrate` three parameters that all kept a silent default —
+`apply_plan`, `rollback_message`, `do_restore`. The discipline stopped at the
+file boundary, and the RESULT's own argument for it (*"a new caller cannot
+inherit the omission by saying nothing"*) applied to none of the three.
+
+Closed three ways, because the parameter shape alone would not have done it:
+
+1. **`apply_plan` and `render` no longer take a root at all.** `Plan` carries
+   `root_arg` — the root the caller *typed* — and `plan_project` requires it
+   with no default, so a plan cannot exist without an answer and these two
+   functions cannot hold a different one. A required parameter still lets a
+   caller fill it with the wrong value; **one root per plan** removes the
+   second place to say it.
+2. **`rollback_message` and `do_restore` are keyword-only with no default**,
+   matching `declare` and `migrate_record`.
+3. **The fixtures pass the root**, so the assertion is finally about a run a
+   reader could have, and the digest-mismatch path — which had **no test at
+   all** — has one. Mutations **M49** and **M50** are red.
+
+**R-N8 — the sweep's ok/bad decision could be disarmed with the suite green.**
+`assertGreaterEqual(len(handed), 12)` guards against the sweep finding
+*nothing*; nothing guarded against it calling *everything* ok, so neutering
+`ROOT` to `re.compile(r"")` left `tests.test_conformance` green while the source
+guard became a no-op and the census in § 1.2 became a table of zeros.
+
+`tests/fixtures/handed_back_spellings.py` is the control, and it is the same
+fixture the recall number comes from: 19 planted defects that must be reported
+and 4 correct rulings that must not. A sweep that reports everything now fails
+on the second half; a sweep that reports nothing fails on the first.
+**M45-M48** neuter `ROOT`, `SAFE_INTERP`, `IS_WHOLLY_A_COMMAND` and
+`FLAG_VALUE` in turn; all four are red.
+
+**R-N13 — the restore point's expected-after entry for the legacy record was
+unpinned.** The call is on the recovery path and this branch added it. Without
+it the restore point keeps the pre-declaration digest for
+`.perry/conformance.md` while the run that converted the record deleted the
+file, so `undo` compares the tree against a signature the run itself
+invalidated.
+
+Green because **no test applied a migration to a project holding a legacy
+record and then restored it** — `tests/test_migrate.py` named `conformance.md`
+in exactly two places, the symlink preflight and the unconvertible-record
+refusal. That round trip is
+`test_a_run_that_converted_a_legacy_record_can_be_restored` now: plant a
+canonical markdown record, apply, assert the markdown is gone and the store is
+there, restore, and assert the tree comes back byte for byte. **M51** deletes
+the call and it is red.
+
+**R-N10, R-N11 and R-N12, which the reviewer recorded rather than charged.**
+R-N10 mutates a test's own matcher and is not addressable. R-N11 and R-N12 gave
+`declare` and `migrate_record` their defaults back and were green because no
+caller omits them today — a shape that protects a *future* caller cannot be
+held by a test that exercises present ones. The reviewer named the remedy and
+round 5 took it: `TestTheRootIsRequiredNotDefaulted`, in both modules, asserts
+via `inspect` that every such parameter is keyword-only with no default, that
+`Plan.root_arg` has no default, and that `apply_plan` and `render` have no such
+parameter at all. **M54** and **M55** are red.

+
+### 7.1 · Round 4 — counted the way the runner makes hard, and bracketed
+
+**`bash tests/run` reports three numbers that look like a failure count and two
+of them are wrong.** The summary line — `✗ N module(s) red` — counts MODULES.
+`grep -c '^FAIL:'` UNDERCOUNTS, because `tests/parallel:283` prints a red
+module's stderr truncated to its last 25 lines **with nothing visibly elided**:
+`test_diagnose` fails twice and only the second `FAIL:` header survives that
+window. The correct count is the sum of the per-module `FAILED (failures=N)`
+lines, and it is what both round-4 rows above report:
+
+```
+grep -oE 'FAILED \(failures=[0-9]+' <log> | grep -oE '[0-9]+$' | paste -sd+ - | bc
+```
+
+All three round-4 runs read **4 test failures across 3 red modules**, and
+`grep -c '^FAIL:'` reads **3** in every one — the trap is live in these exact
+logs. Same red set, by name, in all three: `test_diagnose.py` (2 —
+`test_perry_itself_passes_its_own_id_checks` and the queue-register one that
+loses its header to the window), `test_heading_title.py` (1), and
+`test_kr_progress_provenance.py` (1). **No new red.** 3136 → 3141 is +5: four
+tests in `TestTheCommandTheRefusalNamesIsTheOneTheReaderCanRun` and one in
+`tests/test_migrate.py § TestRecoverable`.
+
+**`test_host_support` did not appear in either round-4 run.** Two round-3
+reviewers measured the same commit within an hour and read 4/3 and 5/4, the
+extra being that already-recorded flake. Recorded because a count that only
+matches when the flake is quiet is a count that will disagree with the next
+reader, and the right answer to that is to say which run this was.

+
+The baseline digest is the same one the V4 round-3 reviewer recorded for this
+tip, which is how the baseline row is known to be about the same bytes it read.
+The run at `5f9f28b` is the one that covers this document as it stands: the
+`b8779f3` run predates the § 7 and § 11 corrections, and `test_heading_title`
+and `test_diagnose` both read `perry/` documents, so a RESULT edit is inside
+their subject. The only commit after `5f9f28b` is the one that adds these three
+lines.
+
+**Mutations, round 4**: `python3 tests/mutate_task_234.py` run whole, in a
+private detached worktree at `b8779f3`, **40/40 red**, `git status --porcelain`
+empty afterwards. Not run in `wt-234` and not in
+`/Users/bytedance/proj/Perry`.
+
+**The four failures are the same four, by name, in both runs** — diffed, not
+counted: `test_no_current_in_the_payload_claims_to_be_a_measurement` and
+`test_perry_itself_passes_its_own_id_checks` (`test_diagnose.py`),
+`test_none_of_them_contains_its_own_id` (`test_heading_title.py`, still the one
+`TASK-050` multi-row document and nothing this row added), and one in
+`test_kr_progress_provenance.py`. **No new failure.** 3098 → 3122 is +24: +22 in
+`test_conformance.py`, +1 in `test_migrate.py` (the symlink preflight became two
+tests), +1 in `test_procedures_call_the_tool.py`. A 22nd landed after that run
+(`test_migrate.py`, the M21 defect below), which is the 3123 of round 1. The V4
+round-2 work adds 13 more — `TestTheRefusalNamesTheLine` (7) and
+`TestTheDefensiveBranchesAreLoadBearing` (6) — for 3136. **The failure sets of
+the baseline and the final run are byte-identical, diffed rather than counted.**
+
+An earlier run at 09:25 had a **fifth** red module, `test_claims.py`, and it was
+this row's own defect: § 12 was appended AFTER `if __name__ == "__main__":`, so
+`python3 tests/test_conformance.py` ran 15 of 19 classes and reported `OK`.
+`tests/test_claims.py § TestNoTestFileEndsEarly` caught it — TASK-209's guard,
+landed on 2026-08-30, firing on the next row. Fixed at `0762a0b`; the entry point
+is the last statement again.
+
+The baseline reproduces the PMO's figure exactly, including the fourth failure —
+`test_heading_title`, firing on a legitimate multi-row evidence document, filed
+and not mine. The four are: 2 in `test_diagnose.py`, 1 in `test_heading_title.py`,
+1 in `test_kr_progress_provenance.py`.
+
+**TASK-249's hazard did not materialise here.** `md5` of the four files
+`tests/run` writes — `.perry/events.jsonl`, `perry/BOARD.md`, `perry/intake.jsonl`,
+`perry/journal/2026-08/2026-08-30.md` — taken before the first run and after the
+last: **identical**, and `git status` clean throughout. The `intake-sweep` is
+idempotent and had already run on `main` at `49d83fc`. Recorded because absence
+of the symptom is not absence of the defect: TASK-249 stands.
+
+**`bin/perry-tasks --dry-run` was not used anywhere in this row.**
+
+### 7.2 · Round 5 — three trees at one base, counted the same way
+
+Counted as § 7.1 says, because the runner makes every other reading wrong: the
+summary line counts MODULES, `grep -c '^FAIL:'` UNDERCOUNTS (`tests/parallel:283`
+truncates a red module's stderr to its last 25 lines with nothing visibly
+elided, and `test_diagnose`'s first header falls outside that window), and
+`failures` and `errors` are different words. Both were summed.
+
+```
+grep -oE 'FAILED \(failures=[0-9]+' <log> | grep -oE '[0-9]+$' | paste -sd+ - | bc
+grep -oE 'FAILED \(errors=[0-9]+'   <log> | grep -oE '[0-9]+$' | paste -sd+ - | bc
+```
+
+| tree | modules | tests | seconds | modules red | **test failures** | errors | `grep -c '^FAIL:'` (the trap) |
+|---|---|---|---|---|---|---|---|
+| `main` @ `4716e39` | 104 | 3124 | 226.5 | 3 | **4** | 0 | 3 |
+| **`main` @ `5b69572`** | 105 | 3148 | 236.0 | 3 | **4** | 0 | 3 |
+| tip `35e0336` | 103 | 3150 | 223.0 | 3 | **4** | 0 | 3 |
+| merge probe `4716e39` + `35e0336` = `f4aff0d` | 104 | 3176 | 226.9 | 3 | **4** | 0 | 3 |
+| **merge probe `5b69572` + `1706a0e` = `8c8cb87`** | 105 | 3200 | 235.4 | 3 | **4** | 0 | 3 |
+
+Sequential on one machine, 15:24 → 15:51 CST, so the seconds are comparable.
+
+**`main` moved twice during this round and both bases are measured rather than
+one being assumed to stand for the other.** `4716e39` is where it stood when
+the worktrees were cut. It moved to **`5b69572`** while the first three runs
+were finishing, and that move is not cosmetic — it brings TASK-249's tree guard
+(`tests/tree_guard.py`, a rewritten `tests/run`) and 24 tests with it, which is
+new machinery watching the suite for writes to the working tree. So `main` was
+re-baselined at `5b69572` and the probe re-cut against it. **Both merges are
+clean, both probes read 4, and the red set is the same three modules by name in
+all five runs.** Nothing this branch adds trips the new guard.
+
+**Red set, by name.** `main` and the tip: `test_diagnose.py` (failures=2 —
+`test_perry_itself_passes_its_own_id_checks` and the one whose header the
+25-line window eats), `test_heading_title.py` (1), and
+`test_kr_progress_provenance.py` (1). Identical in both, and
+`test_heading_title`'s failure is still the single `TASK-050` multi-row review
+document — checked in the log, not assumed, because this round writes a long
+document with many headings into `perry/evidence/`.
+
+**`test_host_support` and what an earlier run of this same probe read.** The
+table above is clean, and it is not the only run this round did. An earlier
+probe — `4716e39` + `cd88312`, the same content minus the last two RESULT
+edits — read **5** failures, the fifth being `test_host_support §
+test_concurrent_registers_do_not_exceed_opencode_cap`, the known intermittent.
+Re-run three times on that tree immediately afterwards: **OK, OK, OK**; absent
+again from the run in the table. Recorded because the flake being quiet in the
+run that got written down is exactly the thing that makes two readers disagree
+about a number, and because a count that has only ever been seen once is worth
+less than a count that has been seen twice with its exception named. It appears
+in none of the three runs above.
+
+**3148 → 3200 on the second probe is +52**: 26 tests on `main` since this
+branch forked, and 26 from the branch. The tip's 3141 → 3150 across round 5 is **+9**,
+enumerated: `test_conformance.py` +4 (the backtick residual, two in
+`TestTheSweepIsMeasuredNotTrusted`, one in `TestTheRootIsRequiredNotDefaulted`)
+and `test_migrate.py` +5 (three in `TestTheRootIsRequiredNotDefaulted`, the
+digest-mismatch rollback, the legacy-record restore round trip).
+
+**md5 bracket** (`git ls-files -z | xargs -0 md5 -q | md5 -q`), before and after
+each run, with `git status --porcelain` **empty** after all three:
+
+| run | before | after |
+|---|---|---|
+| `main` @ `4716e39` | `58f92a848290d83a60dec80dfc66d471` | `58f92a848290d83a60dec80dfc66d471` |

+
+**Mutations, round 5**: `python3 tests/mutate_task_234.py` run whole, in a
+private detached worktree at `debdee8`, **57/57 red**, `git status --porcelain`
+empty afterwards and the tree digest re-checked against the pre-run value
+(`d192a5603f0c9538ce31f3ba9e47648d`, both sides). Not run in `wt-234` and never
+in `/Users/bytedance/proj/Perry`. The only commits after `debdee8` edit this
+document, which no mutation targets.
+
+**The runs are at `35e0336` (tip) and `1706a0e` (the probe's branch side);
+every commit after those two edits this subsection of this document and nothing
+else.** `test_heading_title` and
+`test_diagnose` both read `perry/` documents, so a RESULT edit is inside their
+subject and the run that covers this document is the one at the commit that
+carries it.

+
+## 9 · Blast radius beyond "two functions"
+
+The spec measured one reader and one writer. That was right about the record and
+short about the tree: **five test modules** name the reader or the file and four
+needed real work.
+
+- `tests/test_header_index_is_the_only_fold.py` — `read_conformance` is in
+  `WATCHED`, which is asserted by **set equality** against
+  `header_rule.header_sites()`. The site was **renamed, not removed** (the
+  markdown reader still folds a header cell), so it stays watched under its new
+  name and the workload drives `read_legacy_conformance`. Dropping it instead
+  would have retired a watch on a live reader.
+- `tests/test_one_header_rule.py` — went vacuous (§ 4.5).
+- `tests/test_procedures_call_the_tool.py` — the guard that stops a procedure
+  telling a user to hand-edit the record now matches **both** spellings. A plain
+  rename would have retired it for the file that is still out there; a test for
+  the old spelling was added.
+- `tests/test_migrate.py` — five assertions asserted the **absence** of
+  `.perry/conformance.md`, which after the conversion is the absence of a file
+  nothing writes. Repointed at the store. The symlink preflight test became two.
+
+## 10 · What I could not close
+
+1. **TASK-246 is not dissolved** (§ 5). Stated, measured, and pinned by a test
+   that will go red when it is fixed. Not mine to fix.
+2. **The `"of 6"` KRs are still phrased over six stores and I did not touch
+   them.** The decision not to add a seventh keeps them true today; the tripwire
+   test tells the goals lane the day that changes. `perry/phase/003-linkage.md`
+   is untouched.
+3. **The fixed point has never met a record hand-maintained by anyone but
+   Perry, and that is a substitute, not a sample.** Round 1 said a reviewer with
+   `~/proj/gimegime-pmo` should convert a copy. The reviewer checked: that
+   project has **no conformance record at all**, and **no project on this
+   machine has a `.perry/conformance.md`**. It substituted the five historical
+   versions of Perry's own record from git plus a nine-case hand-edit sweep, and
+   **labelled it a substitute**; this row records it the same way. The
+   population that matters — a record a person other than Perry edited by hand
+   over months — has not been sampled by anyone, and the fixed point is
+   deliberately strict. What that risk now costs is bounded rather than
+   open-ended: § 1.1's diff means a refusal on such a record names the lines,
+   which is the difference between *strict* and *stuck*.
+4. **`.perry/hook.md § High-stakes operations` lists `state-schema.json` and
+   `claims` as the claim surface**, and this row edits that file. The edit is a
+   `note` **string** only: no path was added to or removed from `claims[]` or
+   `files[]`, and the record moves within `.perry/`, which is already claimed
+   territory. Flagged rather than waved through, because the hook says to.
+5. **The board and `perry/tasks.jsonl` are untouched**, as briefed. TASK-246 and
+   TASK-248 are still open rows; § 5 is the input for closing one of them.
+6. **One defensive branch is named rather than pinned**, per the reviewer's
+   ruling: `legacy_record=record.legacy is not None` versus
+   `bool(record.legacy)`. They are the same predicate on every reachable input,
+   so it is an equivalent mutant and no test can distinguish them. Recorded in
+   `TestTheDefensiveBranchesAreLoadBearing`'s docstring so a later sweep does
+   not re-find and re-file it. The other six survivors are now tested (§ 6).
+
+7. **The `perry-conform status` fenced-example case is a message, not a code
+   change.** The V4 round-3 reviewer's § 3: a project whose
+   `.perry/conformance.md` documents its own table format inside a code fence
+   has no way to convert without deleting the example, because the fenced row
+   lands in `record.unreadable` and the refusal says "fix or delete each row by
+   hand". That is the deliberate fail-closed choice and it stands. **Decision:
+   a sentence, as the reviewer suggested** — the unreadable-rows refusal now
+   says the documentation row has to come out for the conversion and can go
+   back into the file it belongs in afterwards, since the store does not carry
+   prose. No behaviour changed and nothing new is measured about it.
+8. **The 12 unreadable-branch call sites do not exercise the diff.** § 1.1.
+   Stated where the coverage is claimed rather than left implied.
+9. **~~Three members of the class are left in `bin/perry-migrate`~~ — all
+   three are fixed in round 5, and the sentence that excused them was wrong.**
+
+   Round 4 wrote: *"all three name a different tool, all three sit in functions
+   with no root in scope"*. The V4 round-4 reviewer resolved each enclosing
+   function off the AST and **two of the three had a root in scope**:
+   `_plan_task_store(plan)` has `plan.project_root` and `plan.state_root` two
+   lines above the refusal. The half of the sentence that was true — the
+   caller's *typed* `root_arg` is not in scope, and threading it changes
+   `plan_project`'s signature — is the half that made the exemption sound
+   structural when it was a decision not to do the work.
+
+   **And the harm was understated, in the direction that matters.**
+   `perry-tasks render --write` accepts `--root` (`bin/perry-tasks:1258`) and
+   **without it writes `state_root / "BOARD.md"` under the reader's current
+   directory** (`bin/perry-tasks:220`). `_plan_task_store` is reached from
+   `plan_project` on both the dry run and the apply. So a reader who ran
+   `perry-migrate --root /their/project` from elsewhere, hit the store-baseline
+   refusal and copied what they were handed **rewrote a different project's
+   board** — strictly worse than the `rc=0` no-op § 1.2's FAIL was about, and
+   filed here as lower priority than the ones that were fixed. `perry-goals
+   commit --migrate` writes `OKR.md § Commitments` and is the same shape one
+   register down.
+
+   **All three carry the root now.** `Plan` holds the root the caller typed;
+   `plan_project` requires it with no default; `_plan_task_store` reads
+   `plan.root_arg`, and `fix_tables` takes it keyword-only through
+   `migrate_text`. Both tools are at zero on both rulings and both are in the
+   suite guard. Mutations **M52** and **M53** drop the flag again and are red —
+   on the source guard alone, because no fixture in this suite triggers either
+   refusal (§ 6.1), which is the whole reason a source rule exists.
+
+   **What is still not verified**: neither refusal is exercised end to end. I
+   did not build a project whose task store disagrees with its board, nor one
+   whose `Commitments` table still carries the pre-split `By when` column, and
+   watch the message come out. The reviewer did not either. The flag is in the
+   template and the template is guarded; the message has not been read off a
+   running tool.
+10. **`bin/perry-lint`'s 22 fix hints all drop the root** (§ 1.2), measured
+   under the crude rule. Pre-existing, in a tool this row does not own, reaching
+   a `perry-conform` reader only through `findings[].fix` in `--json`. Not
+   fixed, not routed around: it is written down with the number and the command
+   that produces it.
+11. **Nothing was measured about a `perry-conform` reader who is NOT in a Perry
+   project at all.** The end-to-end proof stands the reader in a second Perry
+   project, because that is the case where the dropped root is silent. A reader
+   standing in `/tmp` gets the same rc=0 sentence, checked by hand once; it is
+   not pinned by a test.
+12. **A backtick in the project's path is quoted correctly and truncates two
+   INLINE commands in the same message.** `_q` handles it — the indented
+   commands in a refusal are runnable verbatim on a project at ``/tmp/a `b` c``
+   and that is asserted. But this codebase also hands commands back inline,
+   delimited by single backticks, and a backtick inside the argument closes the
+   span early: two branches of `message_for` then print
+   ``` `perry-lint --root '/tmp/a` ``` and the extractor sees the same
+   truncation the reader does. **The break is in the message's markdown, not in
+   the quoting.** Closing it means moving those two commands onto indented
+   lines of their own, or emitting a double-backtick span when the argument
+   contains a backtick — both real fixes, neither this row's FAIL. Measured and
+   pinned by `test_a_backtick_in_the_root_is_quoted_and_what_that_costs`, which
+   **goes red when it is closed**, like the TASK-246 pin. A newline in the path
+   is the same family and is not measured at all: a command carrying one cannot
+   be handed back on a single line, and every extractor here is line-based.
+
+13. **The sweep's census is a lower bound and the bound is now measured, not
+   the class.** 18 of 19 planted spellings, 14 of the round-4 reviewer's 15
+   (§ 1.2). The residual is a cue word outside the closed list, and there is no
+   reason to believe 19 spellings exhaust the ways a Python program can put a
+   command into a message. Every "N members / M left" in this document is a
+   count under one rule.
+14. **The class is much larger outside the two tools this row owns, measured
+   and not fixed.** The round-5 rule over all twelve other `bin/perry-*` tools:
+
+       63 handed-back command(s), 232 mention(s);
+       25 handed back without the caller's root, 19 interpolating a value raw
+
+   `bin/perry-conform` and `bin/perry-migrate` contribute **0 and 0**; the
+   other twelve carry all of it — `perry-tasks` 11, `perry-task` 9,
+   `perry-decide` 2, `perry-goals`, `perry-lint` and `perry-state` 1 each. Most
+   of the rootless ones are `perry-tasks render --write` and `… write
+   --from-board`, the same two commands `§ 10.9` was about, handed back from
+   six more places. **They write.**
+
+   **The 19 over-reports outside these two tools and the split is stated
+   rather than glossed**: 3 are a raw value inside a genuine command phrase
+   (all in `bin/perry-task`) and **16 are `FLAG_VALUE` reading a long flag in
+   ordinary prose** — *"`--prefix {requested}` is not an id prefix"*. That rule
+   is deliberately blunt because it is the only one that can reach the choke
+   point (§ 1.3), and outside a message that hands back a command its
+   precision is poor. Anyone extending the suite guard past these two tools has
+   to sharpen it first; this row does not, and does not pretend the number is
+   clean.
+
+   Not fixed here for the same reason `§ 10.10` gives: a different tool, a
+   different row, and a root threaded through functions that never had one.
+   Written down with the number and the command that produces it.
+
+15. **The widened overclaim guard has a false-positive shape and it is named.**
+   A genuine byte comparison in `bin/perry-conform` or `bin/README.md`
+   described as *"compared byte-for-byte with the record it derived"* would be
+   flagged. There is none today. The looser widening that would have avoided
+   nothing and caught more was tried and rejected on measurement: it fires on
+   `bin/README.md`'s true claim about `perry-config` and on the correcting
+   comment itself (§ 6, M57).
+
+16. **Nothing write-side was run against the repository.** Every suite run,
+   mutation and probe was in a private detached worktree; the end-to-end
+   demonstration in § 1.3 was on a throwaway project under
+   `scratchpad/r5space` that this round created. `perry-conform declare` was
+   run only inside test fixtures' own temporary directories and inside that
+   throwaway. `perry-tasks render --write` and `perry-tasks --dry-run` were
+   never run anywhere. `perry/BOARD.md`, `perry/tasks.jsonl` and
+   `.perry/events.jsonl` are untouched and no identifier was minted.
+
+## 11 · For the record — the sixth vacuous test in three days
+
+`tests/test_one_header_rule.py § TestTheFifthCopy` (§ 4.5) is the **sixth**
+vacuous or self-satisfying test found on this project in three days, and like
+the other five it was found by an agent doing something else — here, sweeping
+call sites of a function it was renaming. Nothing in the suite reports a test
+that has stopped measuring anything; every one of the six was found by a human
+or an agent reading the code for another reason.
+
+This row added one instance of the same class and caught it the same way. The
+`assert_conversion_refuses` helper (§ 1.1) asserted `"refused" in out` — true of
+every refusal, including one that names a command computing no diff — so **14
+test methods, at 16 invocations**, routed through a check that could not fail
+for the reason it existed. It was found by the V4 reviewer, not by the suite.
+The pattern in both: **an assertion whose subject moved, left pointing at
+something that is still true.**
+
+> The count here said "17" until round 4. That is § 4.3's count of *moved*
+> tests, carried into a sentence about *routing*, where it is false — the same
+> defect one register down: **a number whose subject moved**. Corrected in both
+> places, and measured at runtime rather than counted by eye.
+
+**And it happened a third time in this same row, one level deeper.** Round 3
+rewrote both `migrate_record` refusals *under the wall standard's own banner*
+and left the root out of the command they name, while all 16 invocations of the
+now-stricter helper asserted that message **from inside a run that had passed
+`--root`**. `assertIn("perry-conform migrate", message)` was true, and was not
+about the reader. The helper had been hardened to require that a command be
+named; nothing required it to be **the command the caller could run**. That is
+the same class as the two above and the reason § 1.2's proof runs the command
+instead of matching it: an assertion that constructs what it expects cannot see
+what was printed.
+
+**A fourth time, in round 4, and the fourth one is the one worth stopping at.**
+Round 4 built the layer that runs the command instead of matching it — and the
+fixtures it ran it on were `tempfile.TemporaryDirectory()` paths, which never
+contain a space. So the proof executed `shlex.split` on every handed-back
+command, ran what came out, and stayed green over an argument that does not
+survive `shlex.split` on any path a person would call a project. The assertion
+written to stop constructing the expected input was still choosing the input.
+
+The four instances differ, and the difference is the useful part:
+
+| round | what the assertion did | why it could not see the defect |
+|---|---|---|
+| the helper (§ 1.1) | `"refused" in out` | its subject had moved: any refusal satisfied it |
+| round 3 (§ 1.2) | `assertIn("perry-conform migrate", …)` | true of the broken string; not about the reader |
+| round 4 (§ 1.3) | `assertIn(f"--root {root}", …)` | a substring test cannot tell a command from a fragment |
+| round 4's proof (§ 1.3) | ran the command it extracted | **the input never exercised the failure** |
+
+The first three are assertions that stopped measuring. The fourth is a
+*fixture* that never presented the case, and it is a different failure with the
+same effect — which is why round 5's answer is not another assertion but a
+hostile default in the fixture itself, and 19 tests going red the moment it
+landed. **The corresponding half on the source side is the same idea**: the
+sweep's rulings had no positive control at all, so the rule could be turned off
+and the suite would say the class was closed (§ 6.2, R-N8). A guard whose
+inputs are all friendly and a guard whose verdict is never checked are the same
+defect from two sides.

+# TASK-234 — V4 review, round 3 (delta on the corrections)
+
+Subject: branch `coding/task-234-conformance-store`, tip `7d3f93f`.
+Base at review time: `main` at `70bf490` (the `main` baseline below was taken at
+`5367c06`, which is where `main` stood when the worktree was cut; the merge
+probe is against `70bf490`).
+
+Reviewer worked in its own detached worktrees and its own branch. The project
+under review was never modified: every mutation was applied inside
+`scratchpad/r234r3-tip`, a private worktree of this reviewer, restored by `md5`
+after each run, and the worktree was verified clean before and after.
+
+**Verdict: FAIL — one specific, measured defect on the exact standard this
+round was reopened to satisfy. Everything else the round claims verified, with
+one wrong number.**
+
+---
+
+## 0 · Baselines, counted the correct way
+
+`bash tests/run` reports three numbers that look like a failure count. The
+summary line counts **modules**; `grep -c '^FAIL:'` **undercounts**, because
+`tests/parallel:283` prints a red module's stderr truncated to its last 25
+lines with nothing visibly elided — `test_diagnose` fails twice and only the
+second `FAIL:` header survives that window. The correct count is the sum of the
+per-module `FAILED (failures=N)` lines.
+
+Command used for every count below:
+
+```
+grep -oE 'FAILED \(failures=[0-9]+' <log> | grep -oE '[0-9]+$' | paste -sd+ - | bc
+```
+
+| tree | modules | tests | seconds | modules red | **test failures** | `grep -c '^FAIL:'` (the trap) |
+|---|---|---|---|---|---|---|
+| `main` @ `5367c06` | 104 | 3124 | 282.1 | 3 | **4** | 3 |
+| tip `7d3f93f` | 103 | 3136 | 308.2 | 3 | **4** | 3 |
+| merge probe `main@70bf490` + `7d3f93f` | 104 | 3162 | 301.9 | 3 | **4** | 3 |
+
+Red set is identical in all three: `test_diagnose.py` (failures=2),
+`test_heading_title.py` (1), `test_kr_progress_provenance.py` (1). The merge is
+clean (no conflicts) and introduces no new red.
+
+Confirmed by hand that `test_diagnose` reports `FAILED (failures=2)` while only
+one `FAIL:` header survives the 25-line window — the trap is live in these
+exact logs.
+
+**md5 bracket** (`git ls-files -z | xargs -0 md5 -q | md5 -q`), before and
+after each suite run:
+
+- tip: `00e912781c6d368df074f1bba6e87405` → `00e912781c6d368df074f1bba6e87405`
+- probe: `7712c58a8fe39b7a5053c2cd057e30ae` → `7712c58a8fe39b7a5053c2cd057e30ae`
+
+`git status --porcelain` empty in both after the run. Nothing outside the row's
+files moved.
+
+---
+
+## 1 · THE DEFECT — the refusal drops `--root`, and the command it names then succeeds silently against a different project
+
+`bin/perry-conform § message_for` propagates the invocation's root through
+`_root_flag()`:
+
+```
+    perry-conform migrate --root /path/to/project
+```
+
+`bin/perry-conform § migrate_record` — the two refusals this round rewrote and
+the ones the FAIL was about — do not:
+
+```
+Fix those lines, then run:
+    perry-conform migrate
+**Nothing was written.**
+```
+
+Measured end to end on a planted project:
+
+1. `perry-conform check BOARD.md --root $PROJ` routes the reader with
+   `perry-conform migrate --root $PROJ`. (Correct.)
+2. That command refuses, prints the diff — and hands back
+   `perry-conform migrate`, with the root dropped.
+3. Copying that command literally, from where the reader was standing:
+
+```
+$ python3 bin/perry-conform migrate
+perry-conform: nothing to convert — .perry/conformance.jsonl is already this
+project's record (or it has none).
+rc=0
+```
+
+**Exit 0, a success-shaped sentence, and the reader's own record is still
+unconverted and still gating every write.** The brief's rule is "a named
+command that errors is worse than none"; this is the worse-still variant — it
+does not error, it silently reports success about a project the reader did not
+ask about.
+
+Why this is in scope rather than pre-existing noise:
+
+- The sentence containing the command was **rewritten by this round**
+  (`19c8fc5`), under the banner of the wall standard, and the `--root` was not
+  carried into it. The old sentence had the same omission; the correction
+  touched the line and left it.
+- The fix already exists **in the same file, forty lines up**: `_root_flag()`.
+  `message_for` calls it. `migrate_record` does not have the CLI's root string
+  in scope, so this is plumbing, not a design question.
+- The same omission is on the unreadable-rows branch:
+  `Fix or delete each row by hand, then run 'perry-conform migrate' again.`
+  Reached from `declare`, where "again" is also wrong — the reader ran
+  `declare`, not `migrate`.
+- **Every one of the 16 helper invocations asserts this message while running
+  with `--root <tmpdir>`.** `assertIn("perry-conform migrate", message)` is true
+  and is not about the reader's situation in that test. That is a smaller
+  instance of the pattern § 11 of the RESULT names — an assertion sitting
+  beside the thing that matters.
+
+Reproduction: plant a project with `.perry/config.md`, `.perry/hook.md`,
+`BOARD.md`, and a `.perry/conformance.md` that is `LEGACY_HEADER` plus
+`| BOARD.md | 2 | 2026-08-20 | declare |\n\nreminder: check OKR.md\n`; run
+`perry-conform migrate --root $PROJ`; then run the command it names, unchanged,
+from the directory you were in.
+
+---
+
+## 2 · Claim by claim
+
+### (a) Claim 4's "equivalent mutant" — **the claim is correct; I could not kill it**
+
+Named mutant: `bin/perry-conform § verdict`'s
+`legacy_record=record.legacy is not None` versus `bool(record.legacy)`.
+
+Constructed and run: **survived** (`test_the_refusal_names_migrate_and_not_declare`
+green under the mutant). Then I tried to kill it and could not, for these
+reasons, in this order of strength:
+
+1. **`record.legacy` has exactly one assignment**, `viewer/parsers.py:651`,
+   `rec.legacy = legacy` where `legacy = root / CONFORMANCE_LEGACY_FILE`. No
+   other module constructs a `ConformanceRecord` with `legacy` set
+   (`ConformanceRecord(` appears twice, both in `parsers.py`, neither passing
+   `legacy`).
+2. **Every `Path` is truthy, structurally.** Neither `__bool__` nor `__len__`
+   appears anywhere in `Path.__mro__` — checked, not assumed. `Path("") / ".perry/conformance.md"`,
+   `Path(".") / …`, `Path("/") / …` and `Path("//") / …` are all truthy.
+   So the field is `None` (both forms False) or a `Path` (both forms True).
+3. **The only distinguishing values are type violations** — `""`, `0`, `[]` —
+   none of which any code path can produce, and each of which contradicts the
+   declared `legacy: Path | None`. A test that reached them would have to
+   monkeypatch `read_conformance` and would pin a state the program cannot be
+   in. That is the definition of an equivalent mutant, not a missing test.
+4. **The codebase already uses both spellings on this same field**:
+   `bin/perry-conform:816` reads `if record.legacy:`. They have never been
+   treated as different predicates.
+
+**Control, so this is not an excuse for an untested branch:** I mutated
+`legacy_record=record.legacy is not None` → `legacy_record=False`. That is
+**RED** — `test_the_refusal_names_migrate_and_not_declare` fails. The branch is
+load-bearing; only the spelling is indistinguishable. Claim 4 stands.
+
+### (b) Claim 2 — the helper. **Not over-fitted. But the count is wrong: 14, not 17**
+
+Measured at runtime by wrapping `assert_conversion_refuses` and running the
+class (`TestADecoratedRowIsNotADeclaration`, 18 tests, all green):
+
+- **14** distinct test methods route through the helper.
+- **16** invocations (one method,
+  `test_a_canonical_row_inside_an_html_block_is_not_carried_across`, calls it
+  three times under `subTest`).
+- Not 17. The RESULT says "the helper 17 tests route through" (§ 1.1) and "17
+  tests routed through a check that could not fail for the reason it existed"
+  (§ 11). 17 is § 4.3's count of *moved* tests — a different set, and the
+  number has been carried into a sentence about routing where it is false.
+  I verified the class held 18 tests both at `3e11697` and at `7d3f93f`.
+
+**No call site was weakened and none was edited to accommodate the stricter
+helper.** I diffed `tests/test_conformance.py` across the whole correction
+range `3e11697..7d3f93f`: every change to a call site is the *addition* of a
+`names=` argument. No assertion was deleted, relaxed, or carved out. Two call
+sites pass `names=None` — `test_a_path_cell_that_cannot_be_written_back_is_reported_not_crashed`
+and `test_a_bolded_header_row_is_still_not_a_row` — and both still clear the
+"locates the problem" assertion on their own merits (measured below).
+
+**One thing the claim's framing obscures.** Of the 16 invocations, only **4**
+reach the fixed-point refusal that the FAIL was about — the three HTML
+spellings and the hand-edited header. The other **12** take the
+unreadable-rows branch, which prints `line N:` and, as the helper's own comment
+says, "always did". So the helper's new diff-related teeth bite at 4 sites, not
+16. Confirmed by mutation: injecting `perry-conform status` into the
+fixed-point refusal reddens exactly 4.
+
+### (c) The negative assertion — **verified non-vacuous at every call site**
+
+I re-ran each of the 16 invocations and captured the actual
+`out["refused"]` string:
+
+- shortest message: **271 characters**; none empty; every one reaches the
+  `assertNotIn("perry-conform status", …)`.
+- every one satisfies the "locates" regex for real: 4 via
+  `--- .perry/conformance.md` (a diff), 12 via `line \d+:` (a numbered line).
+- every one contains `perry-conform migrate`.
+- none contains `perry-conform status`.
+
+The negative is therefore not passing by emptiness or by an unreachable path.
+It is also load-bearing: see R-N2 below.
+
+### (d) Mutations re-run independently — **17 run, 16 killed, 1 survivor and it is
+### the declared equivalent one**
+
+Discipline: anchored on exact text with a uniqueness assertion, `__pycache__`
+cleared, slept past the whole-second boundary before and after,
+`PYTHONDONTWRITEBYTECODE=1`, restored by `md5` with the digest asserted, target
+asserted GREEN before mutating, refused to start on a dirty tree. Harness:
+this reviewer's own, not the row's.
+
+| id | site | mutation | result |
+|---|---|---|---|

+| R-N5 | `bin/perry-conform:649` | `record_diff(canonical, canonical)` (a diff of nothing) | RED (4) |
+| R-BFB | `bin/perry-conform:603` | "line-for-line" → "byte-for-byte what" | RED |
+| R-CRLF | `bin/perry-conform:632` | `read_text()` → `read_bytes().decode()` (make the comparison actually byte-for-byte) | RED |
+| R-EQ | `bin/perry-conform:252` | `record.legacy is not None` → `bool(record.legacy)` | **GREEN — equivalent, see (a)** |
+| R-EQ-CTL | `bin/perry-conform:252` | → `legacy_record=False` | RED |
+| M25 | `viewer/parsers.py:694` | non-string `path` guard → `if False` | RED |
+| M26 | `viewer/parsers.py:698` | non-string `declared`/`route` guard → `if False` | RED |
+| M27 | `viewer/parsers.py:703` | `route or "declare"` → `route` | RED |
+| M28 | `viewer/parsers.py:700` | provenance `isinstance` filter → `or ""` | RED |
+| M29 | `viewer/parsers.py:655` | delete the `except OSError` around `read_text` | RED |
+
+R-N1..R-N5 are mine, not the row's: they mutate the **source** so that each of
+the helper's four new requirements has to fire on its own — names a runnable
+command (R-N1), never names `status` (R-N2), locates the problem (R-N3 for the
+12 unreadable-branch sites, R-M22/R-N5 for the 4 diff sites), quotes the *right*
+line (R-N4). All four fire. The helper is not decorative.
+
+**Claim 6 ("29/29") is not verified.** I re-ran 8 of the row's 29 (M22–M29)
+plus M15's branch as a control, and added 9 of my own. I did not re-run
+M1–M14, M16–M21. No survivor was found other than the declared equivalent one.
+
+### (e) The wall standard — **met on three branches, broken on the `--root` path**
+
+| branch | ends in a command? | does the command work? |
+|---|---|---|
+| `migrate_record` unreadable-rows refusal | yes — `perry-conform migrate` | from inside the project: yes. With `--root`: **no — see § 1** |
+| `migrate_record` fixed-point refusal | yes — `perry-conform migrate` | same |
+| `message_for` legacy-record branch | yes — `perry-conform migrate --root <path>` | yes, verified |
+| `perry-migrate apply` rollback | yes — `perry-migrate restore 2026-08-30-110544` | yes — ran it, rc 0, `restored: ['BOARD.md', '.perry/conformance.md']` |
+
+Full text of a real refusal, from a real planted project (not a fixture

+```
+
+Fixing exactly those lines and re-running from inside the project converts
+cleanly (rc 0, `carried 1 declaration(s)`, markdown deleted). The mitigation is
+real; only the invocation is under-specified.
+
+### Claims 1, 3, 5
+
+- **Claim 1 — verified.** The refusal carries a unified `difflib` hunk with
+  both file labels, states the `-`/`+` semantics in prose above the hunk, and
+  ends in a command. R-M22 / R-N5 / R-N4 all redden it.
+- **Claim 3 — verified, both halves load-bearing.** R-BFB (put the phrase back
+  in the source) and R-CRLF (make the comparison genuinely byte-for-byte) both
+  redden `test_a_crlf_record_converts_and_the_wording_does_not_say_byte`. Note
+  the source guard is the literal substring `"byte-for-byte what"`; a reworded
+  overclaim ("byte for byte", "byte-for-byte identical to what") would slip
+  past it, and `bin/README.md` is not covered by the guard at all — its two
+  remaining uses of the phrase there are correct today.
+- **Claim 5 — verified.** M23 is a live branch, not a defensive one: without
+  `max(0, …)`, `dropped` is negative for any diff shorter than the cap,
+  `if dropped:` is true for a negative number, and every ordinary refusal would
+  end "… and -37 more diff line(s)". M24's point is real too — the cap test now
+  recomputes the expected number from the file on disk and asserts it, and
+  hard-coding the count to `0` reddens it.
+
+---
+
+## 3 · Observation, not a defect
+
+A project whose `.perry/conformance.md` documents its own table format inside a
+code fence has **no way to convert without deleting the example**: the fenced
+row lands in `record.unreadable`, the first refusal branch fires, and its
+instruction is "fix or delete each row by hand". That is the deliberate
+fail-closed choice this row argues for and I am not disputing it — but the
+refusal's wording tells such a reader to delete documentation, and the diff
+mitigation does not reach that branch. Worth a sentence in the message rather
+than a code change.
+
+---
+
+## 4 · What I did NOT verify
+
+1. **21 of the row's 29 mutations** (M1–M14, M16–M21). Not re-run. "29/29" is
+   unconfirmed beyond the 8 I checked.
+2. **A `.perry/conformance.md` hand-maintained by anyone but Perry.** Same gap
+   the RESULT declares in its own § 10.3. I did not find one on this machine
+   either and did not look beyond it.
+3. **The board and `perry/tasks.jsonl`.** Untouched and unread by me; the PMO
+   owns them.
+4. **A `main` baseline at `70bf490`.** My `main` baseline is at `5367c06`. The
+   probe's failure count and red set match both other runs, so no new red is
+   attributable to the merge, but the three trees are not at one base.
+5. **`perry-migrate restore` without `--root`.** The fixture always passes
+   `--root`; I did not check whether that command carries the same omission as
+   § 1.
+6. **The `bin/README.md`, `reference/config.md` and `schema/state-schema.json`
+   edits** beyond reading the correction-range diff. No behaviour was measured
+   against them.
+7. **Anything under `.perry/events.jsonl`.** No write-side Perry tool was run
+   against the repository or any worktree of it; `perry-conform declare` was
+   never run, anywhere.
+
+---
+
+## 5 · Verdict
+
+**FAIL.**
+
+The corrections are, with one exception, exactly what the round asked for and
+they hold up under independent attack. The equivalent-mutant claim — the one I
+was sent to break — is correct, and I say so having tried the three avenues
+that could have broken it. The helper is hardened without over-fitting and
+without a single weakened call site. The diff, the cap, and the two mutation
+findings (M23, M24) are all real and all pinned.
+
+The FAIL is § 1 and only § 1: **the refusal this round rewrote to satisfy the
+wall standard hands the reader a command with the root dropped, and that
+command exits 0 with a success-shaped sentence about a different project.** The
+standard is stated in this file; the helper for meeting it is in this file; the
+sentence that violates it was edited in this round. One number in the RESULT is
+also wrong — the helper is routed through by 14 tests, not 17 — and should be
+corrected in both places it appears (§ 1.1 and § 11).
+
+---
+
+*checked:* mutations and probes were run in this reviewer's own detached
+worktrees (`scratchpad/r234r3-tip`, `r234r3-main`, `r234r3-probe`), never in
+`/Users/bytedance/proj/Perry`. Every mutated file was restored and its `md5`
+asserted; both worktrees verified clean by `git status --porcelain` afterwards.
+No `git checkout`, `stash`, `reset` or `clean` was run in any reviewed tree. No
+write-side Perry tool was run. No identifiers were minted.

+# TASK-234 — V4 review, round 4 (delta on the round-3 corrections)
+
+Subject: branch `coding/task-234-conformance-store`, tip `f783dd5`.
+Base: `main` at `014dc6a`. `main` is live and moved twice during this round —
+`1163f74` when the worktrees were cut, `014dc6a` when the baseline ran,
+`1cbc025` by the time this file was written. Every number below is against
+`014dc6a`, and the merge probe is `014dc6a` + `f783dd5` = `e5296a1`.
+
+Reviewer worked in its own detached worktrees (`scratchpad/r234r4-tip`,
+`-main`, `-probe`, `-mut`, `-mut2`) and its own branch. The project under
+review was never modified. Every mutation was applied inside a private
+worktree, restored by exact text with the file `md5` asserted, and the tree
+verified clean by `git status --porcelain` before and after each run.
+
+**Verdict: FAIL — one live, measured defect on the standard this row has now
+been reopened on twice, plus three green mutations.** The round-3 FAIL itself
+is genuinely fixed; the sweep, the end-to-end proof and the two GREEN findings
+(M35, M36) all hold up. The FAIL is § 1.

+different words and both were counted. Red set identical in all three, by name:
+`test_diagnose.py` (2), `test_heading_title.py` (1),
+`test_kr_progress_provenance.py` (1). The merge is clean (no conflicts) and
+introduces no new red. **`test_host_support` did not appear in any of the three
+runs**, so none of these numbers depends on the known intermittent being quiet
+in one run and not another.
+
+The three runs were sequential on one machine, not parallel, so the seconds are
+comparable.
+
+**md5 bracket** (`git ls-files -z | xargs -0 md5 -q | md5 -q`), before and
+after each suite run, `git status --porcelain` empty after each:

+
+## 1 · THE DEFECT — the handed-back command is built unquoted
+
+This is the same standard as the round-3 FAIL, one register further down. Round
+3: the command named the wrong project. Round 4: the command names the right
+project **in a form the reader cannot run**.
+
+`bin/perry-conform § _root_flag` is the whole of it:
+
+```python
+def _root_flag(root_arg: str | None) -> str:
+    return f" --root {root_arg}" if root_arg else ""
+```
+
+No quoting, and `shlex.quote` appears nowhere in `bin/` or `viewer/` — checked,
+not assumed.
+
+**Measured end to end on a planted project** (a throwaway fixture of my own
+making, under `scratchpad/r4space/My Project`; nothing was run against Perry or
+any worktree of it):
+
+```
+$ cd .../r4space/elsewhere
+$ python3 bin/perry-conform migrate --root "/…/r4space/My Project"
+    --- .perry/conformance.md
+    +++ what Perry reads out of it
+    @@ -15,3 +15 @@
+     | BOARD.md | 2 | 2026-08-20 | declare |
+    -
+    -reminder: check OKR.md
+
+Fix those lines, then run:
+    perry-conform migrate --root /…/r4space/My Project        ← unquoted
+**Nothing was written.**
+```
+
+The reader fixes the file exactly as told, then copies that line:
+
+```
+$ python3 bin/perry-conform migrate --root /…/r4space/My Project
+perry-conform: refused — usage: perry-conform migrate — it takes no file. The
+conversion carries the WHOLE record across or refuses; …
+rc=1
+```
+
+`Project` was parsed as a file argument. The reader's `.perry/conformance.md`
+is still there, no `.perry/conformance.jsonl` was written, and the error message
+is about a mistake the reader did not make. With the same root quoted, the same
+command exits 0 and converts — so the file was always fine and only the
+handed-back spelling was wrong.
+
+Why this is in scope rather than pre-existing noise:
+
+- **It is in the sentence this round wrote.** Both `migrate_record` refusals
+  gained `{r}` in this round's `c184164`. Before it they had no root at all
+  (the round-3 FAIL); after it they have one that does not survive a copy.
+- **The row's own standard names it.** § 1.2: *"a named command that errors is
+  worse than none"*. This is that case, measured.
+- **It is the whole class, not one site.** Every one of the 14 handed-back
+  commands `bin/perry-conform` emits and all four in `bin/perry-migrate` are
+  built by `_root_flag`. That includes the `message_for` legacy branch the
+  round-3 reviewer verified as *"yes, verified"* — verified against a
+  space-free `tempfile` root. Reproduced on that branch too:
+
+```
+  perry-conform migrate --root /…/r4space/My Project
+```
+
+- **The row's own end-to-end proof is one character from catching it.**
+  `test_the_named_command_converts_the_readers_project_from_elsewhere` takes the
+  command out of the message and runs it through `shlex.split` — the exact
+  parser that exposes this — but `Project()` uses
+  `tempfile.TemporaryDirectory()`, which never yields a path with a space. I
+  replayed the test's own steps verbatim with a spaced root:
+
+```
+named:       ['perry-conform migrate --root /…/r4space/My Project']
+shlex.split: ['perry-conform', 'migrate', '--root', '/…/r4space/My', 'Project']
+rc = 1 ; reader's store written? False ; markdown still there? True
+```
+
+  So the proof would go red today if a single fixture root contained a space.
+
+- **Neither guard sees it.** `assert_every_command_carries` asserts
+  `f"--root {root}" in cmd`, which is true of the broken line;
+  `tests/sweep_handed_back_commands.py`'s `ROOT` regex asks only whether
+  `--root` is present, never whether the phrase is runnable.
+
+**Severity, stated plainly so it is not overstated.** This is strictly less
+harmful than the round-3 defect: it fails loudly (rc=1) rather than succeeding
+about someone else's project, and it only bites a project path containing a
+space. It is also a pre-existing spelling that this round propagated to five
+new sites rather than one it invented. But it is the same standard, in the same
+sentence, found by doing the same thing round 3 did — running the command the
+refusal hands back — and the fix is one call to `shlex.quote` in `_root_flag`.
+
+---
+
+## 2 · Green mutations
+
+Discipline for all of them: anchored on exact text with a uniqueness assertion,
+`__pycache__` cleared, slept past the whole-second boundary before and after,
+`PYTHONDONTWRITEBYTECODE=1`, target asserted **GREEN** before mutating,
+restored by exact text with the file `md5` asserted and the tree re-checked
+clean. Harness: this reviewer's own, in `scratchpad/r234r4-mut` and `-mut2`.
+Target set for every run below: **the whole of `tests.test_conformance` and
+`tests.test_migrate`** unless noted.
+
+### 2.1 · R-N3 and R-N4 — two of three call sites drop the root, green
+
+`bin/perry-migrate § apply_plan` calls `rollback_message` three times. Round 4
+threaded `root_arg` into all three. Only one of the three is pinned.
+
+| id | site | mutation | result |
+|---|---|---|---|
+| R-N3 | `apply_plan`, the **write failed** path (`raise Refused(rollback_message(point, e.key, exc, root_arg=root_arg))`) | `root_arg=None` | **GREEN — SURVIVOR** |
+| R-N4 | `apply_plan`, the **digest mismatch** path (`allow_changed=allow_changed, root_arg=root_arg`) | `root_arg=None` | **GREEN — SURVIVOR** |
+| R-N5 | `apply_plan`, the **declaration refused** path (`}, root_arg=root_arg)`) | `root_arg=None` | RED (1) |
+
+The two survivors are TASK-044 guarantee 3's own paths — a write that fails
+(read-only directory, full disk, permission revoked mid-run) and a write that
+lands with the wrong digest. Both hand the reader
+`perry-migrate restore <run-id>` as the way back. With the root dropped there,
+a reader who ran `perry-migrate apply --root /their/project` from elsewhere is
+handed a restore command that looks for the restore point under whatever
+project they are standing in.
+
+**Why they are green is the round-3 defect one file over.** The tests that
+exercise those two paths call `M.apply_plan(plan, SCHEMA)` — positionally, with
+no `root_arg` — so `root_arg` is `None` on both sides of the mutation and
+`_root_flag` returns `""` either way. The assertion about the handed-back
+command is being made from inside a run that never passed a root. That is
+verbatim the sentence § 11 of the RESULT writes about the 16 helper
+invocations.
+
+Controls, so this is not an artefact of my target set: **R-N6** (make
+`bin/perry-migrate § _root_flag` return `""` unconditionally) is RED on two
+tests, and **M36** (mutate `rollback_message` itself) is RED — so the function
+is guarded; only two of its three call sites are not.
+
+### 2.2 · R-N8 — the sweep's ok/bad decision is unguarded
+
+`tests/test_conformance.py § test_no_refusal_in_perry_conform_names_a_command
+_without_the_root` **imports** `tests/sweep_handed_back_commands.py` rather
+than restating its rule — which the RESULT argues for, correctly. The cost is
+that the rule is now shipped code with no positive control.
+
+| id | site | mutation | result |
+|---|---|---|---|
+| R-N8 | `sweep § ROOT` | `re.compile(r"...")` → `re.compile(r"")` (match everything, so nothing is ever MISSING) | **GREEN — SURVIVOR** (whole of `tests.test_conformance`) |
+| R-N9 | `sweep § CUE` | `re.compile(r"(?!x)x")` (match nothing, so no phrase is ever an instruction) | RED (1) — the `assertGreaterEqual(len(handed), 12)` fires |
+
+The test's non-vacuity check guards against the sweep finding **nothing**. It
+does not guard against the sweep calling **everything ok**. A one-character
+edit to `ROOT` turns the source guard into a no-op *and* makes
+`python3 tests/sweep_handed_back_commands.py --all …` report a census of zero
+members, which is the number § 1.2's table is built from. The row's own name
+for this shape is "an assertion sitting beside the thing that matters".
+
+The missing control is cheap: assert the sweep reports MISSING on a known-bad
+snippet.
+
+### 2.3 · R-N13 — the restore point's expected-after entry is unpinned
+
+| id | site | mutation | result |
+|---|---|---|---|
+| R-N13 | `bin/perry-migrate § apply_plan`, the `update_expected_after(point, P.CONFORMANCE_LEGACY_FILE, …)` call | delete it (`pass`) | **GREEN — SURVIVOR** (whole of `tests.test_migrate`) |
+
+That call was introduced by this branch (`095b5da`). Without it the restore
+point keeps the pre-declaration digest for `.perry/conformance.md`, while a run
+that converted the record has deleted the file — so `undo` is comparing against
+a signature the run itself invalidated. Corroborated by coverage: the only two
+places `tests/test_migrate.py` names `conformance.md` are the symlink preflight
+(line 732) and the unconvertible-record refusal (line 905). **No test applies a
+migration to a project holding a legacy record and then restores it**, which is
+the round trip this call exists for.
+
+I did not demonstrate a wrong answer out of it — only that a call this branch
+added, on the recovery path, is unpinned.
+
+### 2.4 · R-N10, R-N11, R-N12 — unpinned by construction, recorded not charged
+
+| id | site | mutation | result |
+|---|---|---|---|
+| R-N10 | `tests/test_conformance.py`, the `overclaim` regex | `re.compile(r"(?!x)x")` | GREEN |
+| R-N11 | `bin/perry-conform § declare` | `*, root_arg: str | None = None` (give the keyword-only parameter a default back) | GREEN |
+| R-N12 | `bin/perry-conform § migrate_record` | same | GREEN |
+
+None of these is charged as a defect. R-N10 mutates a test's own matcher, which
+is green almost everywhere. R-N11 and R-N12 are green because no caller in the
+tree omits the argument — the no-default shape protects a *future* caller, and
+no test can hold that. They are recorded so a later sweep does not re-find them
+and file them as findings. (A signature assertion via `inspect` would pin them
+if the row wants the shape guaranteed rather than merely written.)
+
+---
+
+## 3 · The three same-line mutations — two claims do not survive measurement
+
+§ 6.1 argues: *"M32 is invisible to the source guard … M34 is invisible to
+**both** … and is caught only by the end-to-end test … Three layers, one per
+failure mode, each demonstrated by the mutation the other two miss."*
+
+Measured, whole of `test_conformance` + `test_migrate`, distinct failing
+methods in brackets:
+
+| mutation | failures | distinct methods | source guard red? | helper red? | end-to-end red? |
+|---|---|---|---|---|---|
+| M30 / M40 (`{r}` deleted from the fixed-point template) | 8 | 6 | **yes** | yes (4) | yes |
+| M34 (`--root /nowhere-at-all`, spelled correctly) | 7 | 5 | no | **yes (4)** | yes |
+| M32 (`_root_flag(None)` — the runtime value) | 20 | 18 | no | yes (16) | yes |
+
+- **M34 is *not* invisible to the helper.** `assert_every_command_carries`
+  asserts `f"--root {root}"` — the *exact* root, not the presence of a
+  `--root` — so a correctly-spelled wrong root reddens every helper invocation
+  that reaches the fixed-point branch. Four of them do, and all four go red.
+  The claim that only the end-to-end test catches M34 is false as measured. The
+  layer that is genuinely alone on M34 is not needed for M34; what the
+  end-to-end test uniquely covers is *running* the command, which is what
+  caught § 1 above.
+- **M40 is the same bytes as M30**, so "M40 is caught only by reading the
+  source" cannot be true of either; it reddens the source guard, the helper and
+  the end-to-end test together.
+- **M32's "reddens all 16 at once" checks out.** 20 failures = the 16 helper
+  invocations + 4 other tests; 18 distinct methods = the 14 helper methods + 4.
+  That is an independent confirmation of § 1.1's corrected **14 methods / 16
+  invocations**, and of its 4 / 12 split: M34, which mutates only the
+  fixed-point branch, produces exactly 4 helper failures.
+
+The three layers are all real and all load-bearing. The *argument* for why
+three are needed is weaker than stated.
+
+---
+
+## 4 · M35 and M36 — re-run, both now red for the stated reason
+
+| id | mutation | result | failing |
+|---|---|---|---|
+| M35 | `apply_plan` stops carrying its root into `C.declare` (`root_arg=None`) | RED (1) | `test_an_unconvertible_markdown_record_refuses_and_names_the_way_back` |
+| M36 | `rollback_message` drops `{_root_flag(root_arg)}` from `perry-migrate restore <id>` | RED (1) | same |
+
+**M36's original path is still covered.** The reason M36 was green when first
+pointed at the successful-run test is that `perry-migrate restore <id>` is
+named on two code paths. I mutated the *other* one:
+
+| id | mutation | result |
+|---|---|---|
+| R-N7 | `render`'s `undo with: perry-migrate restore {applied['run']}{r}` → drop `{r}` | RED (1) — `test_every_way_back_this_tool_names_carries_the_root` |
+
+So both surfaces are guarded, and re-pointing M36 did not abandon the first
+one. Two more plumbing hops I added, both RED:
+
+| id | mutation | result |
+|---|---|---|
+| R-N1 | the CLI stops passing `root_arg` into `apply_plan` | RED (1) |
+| R-N2 | the CLI stops passing `root_arg` into `do_restore` | RED (1) |
+
+---
+
+## 5 · The sweep, reviewed as code
+
+### 5.1 · It does what the RESULT says on the trees it names — confirmed
+
+```
+$ python3 tests/sweep_handed_back_commands.py bin/perry-conform
+14 handed-back command(s), 16 mention(s); 0 handed back without the caller's root
+rc=0
+```
+
+And the before/after census reproduces exactly. Run over
+`git show 7d3f93f:bin/perry-conform` and `…:bin/perry-migrate`:
+
+```
+7 handed back without the caller's root      (2 in perry-conform, 5 in perry-migrate)
+```
+
+and over the tip's eight files with the row's own command: **3 left, all in
+`bin/perry-migrate`**, rc=1. The `14 / 2 → 14 / 0` and `7 / 5 → 7 / 3` table in
+§ 1.2 is correct.
+
+I also read all 16 of `bin/perry-conform`'s "mention" rulings by hand. Every
+one is genuinely a mention — usage strings, provenance values, prose naming a
+tool the reader is told *not* to run. No false negative there.
+
+### 5.2 · Recall — the blind spot is five shapes, not the one the docstring names
+
+The sweep's docstring states one blind spot: *"a command built into a name that
+says nothing, e.g. `s = "perry-x …"`"*. I planted **15 genuinely root-dropping
+handed-back commands**, in a file of my own, and ran the shipped sweep over it:
+
+| # | spelling | found? |
+|---|---|---|
+| 1 | f-string, indented continuation line (the shipped shape) | ✔ |
+| 2 | f-string, ``run `perry-conform migrate` `` inline | ✔ |
+| 3 | `"…".format(n=3)` | ✔ |
+| 4 | `"…" % 3` | ✔ |
+| 5 | `+` concatenation across two literals | ✔ |
+| 6 | `+` concatenation splitting the command mid-word | ✔ |
+| 7 | module constant `MIGRATE_HINT`, interpolated | ✘ |
+| 8 | local `fix = "perry-conform migrate"`, interpolated | ✘ |
+| 9 | `msg = …` then `msg += "    perry-conform migrate\n"` | ✔ |
+| 10 | the same, split mid-word (phrase reported truncated to `perry-conform`) | ✔ |
+| 11 | `"\n".join([...])` | ✔ |
+| 12 | a nested helper `def way_out(): return "perry-conform migrate"` | ✘ |
+| 13 | prose cue the CUE list does not contain (*"is spelled …"*) | ✘ |
+| 14 | a dict of fixes, `FIXES["legacy"]` | ✘ |
+| 15 | two bare `print()` calls | ✔ |
+
+**10 found, 5 missed — recall 67 % on plausible spellings.** The `.format`,
+`%`, `+`-concatenation and multi-statement cases the brief asked about are all
+caught, and that is a real strength: the AST walk earns its keep. What escapes
+is any command that reaches the message **through a name** — module constant,
+local, dict value, helper return — unless that name happens to match
+`NAMED_AS_COMMAND`, plus any instruction whose cue word is not one of
+`run / with / is / try / use`.
+
+Consequence for the RESULT's wording: § 1.2 says *"this is a class, and here is
+how many members it has"* and prints `7` and `3`. Those are **lower bounds
+under one rule**, not a census. The row is honest that a blind spot exists; it
+under-describes its size. Note that § 1's defect is a sixth shape the sweep
+cannot see at all, because the phrase it looks for is present and correct.
+
+### 5.3 · The three excused members — the excuse is inaccurate for two
+
+§ 10.9 excuses the three remaining `bin/perry-migrate` members as *"all three
+name a different tool, all three sit in functions with no root in scope"*.
+Resolved the enclosing function of each off the AST:
+
+| site | phrase | enclosing function | root in scope? |
+|---|---|---|---|
+| `bin/perry-migrate:672` | `perry-goals commit --migrate` | `fix_tables(lines, spec, schema, changes, rewritten)` | **no** — excuse holds |
+| `bin/perry-migrate:1681` | `perry-tasks render --write` | `_plan_task_store(plan)` | **yes** — `plan.project_root` and `plan.state_root`, used two lines above |
+| `bin/perry-migrate:1681` | `perry-tasks write --from-board` | same | **yes** |
+
+The *caller's typed* `root_arg` is genuinely not in scope, and threading it
+would change `plan_project`'s signature — that part of § 10.9 is right. But
+"functions with no root in scope" is not, for two of the three, and it is the
+half of the sentence that makes the exemption sound structural.
+
+More importantly, **§ 10.9 does not say what those two commands do.**
+`perry-tasks render --write` accepts `--root` (`bin/perry-tasks:1258`) and
+without it writes `state_root / "BOARD.md"` under the reader's *current
+directory* (`bin/perry-tasks:220`). `_plan_task_store` is reached from
+`plan_project`, which runs on both the dry run and the apply. So a reader who
+runs `perry-migrate --root /their/project` from elsewhere and hits the
+store-baseline refusal is handed a command that, copied, **rewrites a different
+project's board** — strictly worse than the rc=0 no-op the round-3 FAIL was
+about. The row files these three as lower priority than the ones it fixed; on
+harm they are higher.
+
+I did not build the fixture that triggers that refusal end to end (§ 8).
+
+---
+
+## 6 · The signature change
+
+`root_arg` is keyword-only with no default on both functions, confirmed by
+`inspect`:
+
+```
+migrate_record: (project_root: 'Path', *, root_arg: 'str | None') -> 'dict | None'
+declare       : (…, run: 'str' = '', *, root_arg: 'str | None') -> 'dict'
+```
+
+- **Callers, enumerated.** `migrate_record`: two, both in `bin/perry-conform`
+  (`declare`, and the `migrate` subcommand). `declare`: two —
+  `bin/perry-conform § main` and `bin/perry-migrate § apply_plan` via
+  `C.declare`. No test calls either directly (`tests/` mentions them only
+  inside `tests/mutate_task_234.py`'s anchor strings). `bin/perry-task`,
+  `bin/perry-goals` and `bin/perry_md_store.py` load `perry-conform` as a
+  module but reach only `gate()`, `_root_flag()`, `lint()`, `load_schema()`
+  and `state_files()` — checked, not assumed. **No call site works only by
+  passing positionally, and none is stubbed.**
+- **Omission is a `TypeError`, and nothing swallows it.** Verified by calling
+  both with the argument missing:
+  `TypeError: migrate_record() missing 1 required keyword-only argument: 'root_arg'`.
+  `bin/perry-conform § main` and `bin/perry-migrate § main` both catch
+  `Refused` only; `apply_plan`'s handler is
+  `except (OSError, Refused, C.Refused, ValueError)`. The one
+  `except (…, TypeError)` in `bin/perry-migrate` (line 2033) is inside
+  `load_restore_payload` and is nowhere near this path. `bin/perry-diagnose`'s
+  broad `except Exception` blocks never reach `declare`.
+- **The discipline stops at the file boundary, and that is worth saying.**
+  `bin/perry-migrate`'s three new root parameters all keep a silent default:
+
+```
+apply_plan       (plan, schema, declare=True, root_arg: str | None = None)
+rollback_message (point, key, why, allow_changed=None, root_arg: str | None = None)
+do_restore       (project_root, positional, do_list, as_json, root_arg=None)
+```
+
+  The RESULT's own argument for the no-default shape — *"a new caller cannot
+  inherit the omission by saying nothing"* — does not apply to any of these,
+  and § 2.1's two green survivors are exactly a caller saying nothing.
+
+---
+
+## 7 · What else was checked and holds
+
+- **The end-to-end extraction is genuinely programmatic.** `commands_named`
+  reads the message text; the test does `argv = shlex.split(cmd)` and runs
+  `["python3", CONFORM, *argv[1:]]`. Nothing in the path reconstructs the
+  expected command. The two assertions that touch the command's shape are
+  negative (`assertNotEqual(argv[1:], ["migrate"])`) and an identity check on
+  `argv[0]`. Step 2 measures the harm on the live tree before step 4 runs the
+  named command, so a tree where the bare command *worked* would be reported
+  rather than silently passed.
+- **No call site of `assert_conversion_refuses` was weakened.** I diffed
+  `tests/test_conformance.py` across `7d3f93f..f783dd5`: every change is an
+  addition; no assertion was deleted or relaxed. `assert_every_command_carries`
+  is applied unconditionally at the helper, not behind a flag.
+- **`perry-conform` really is at zero.** Sweep rc=0, empty finding list, and
+  all 16 mention rulings read by hand.
+- **Ten of the row's own numbered mutations re-run independently, all RED:**
+  M4, M6, M11, M12, M16, M30/M40, M32, M34, M35, M36. M4, M6, M11, M12 and M16
+  are in the M1–M21 block that round 3 explicitly did **not** re-run, so they
+  had never been reproduced by anyone. M12 reddens two tests, one of which is
+  the new end-to-end proof — a useful sign that the proof is wired to real
+  behaviour and not only to the message.
+- **The CRLF guard is real but narrower than "the phrase describing what the
+  file is compared against".** The regex is
+  `byte[- ]for[- ]byte(\s+identical)?\s+(to\s+)?what`. Of nine plausible
+  overclaims I put to it, it caught 3 and **evaded 5**: *"byte-for-byte
+  identical to the file … wrote"*, *"compared byte-for-byte against what …"*,
+  *"byte-for-byte with what …"*, the same phrase with a U+2011 non-breaking
+  hyphen, and *"bytewise"*. It does catch M38's exact shape. The positive pins
+  are **not vacuous** — `"ine-for-line, not byte-for-byte"` occurs exactly once
+  in each of `bin/perry-conform` and `bin/README.md`, in the correcting
+  sentence itself, and deleting it reddens the test (M39). But the pin is a
+  substring check: a file could keep that sentence and contradict it elsewhere
+  in an evading spelling.
+- **The corrected numbers are correct.** 14 helper methods / 16 invocations,
+  and the 4 / 12 fixed-point / unreadable split, both independently confirmed
+  by the M34 and M32 failure counts (§ 3).
+
+---
+
+## 8 · What I did NOT verify
+
+1. **The row's `40/40`.** I re-ran 10 of the 40 and added 13 of my own. M1–M3,
+   M5, M7–M10, M13–M15, M17–M21, M31, M33, M37, M38, M39 were not re-run by me,
+   so `40/40` remains unconfirmed beyond the 10 I checked plus the 8 round 3
+   checked. R-N13 is adjacent to the row's M17 but is a different site — treat
+   it as mine, not a reproduction of theirs.
+2. **The `_plan_task_store` refusal end to end.** I established statically that
+   `plan.project_root` is in scope, that the refusal is reachable from
+   `plan_project` on both dry run and apply, and that `perry-tasks render
+   --write` writes the cwd project's `BOARD.md` when given no `--root`. I did
+   not build a fixture whose task store disagrees with its board and watch the
+   message come out.
+3. **The `fix_tables` / `perry-goals commit --migrate` member**, beyond
+   confirming no root is in scope there.
+4. **A `.perry/conformance.md` hand-maintained by anyone but Perry.** Same gap
+   the RESULT declares in § 10.3 and round 3 declared. I did not look for one.
+5. **The board and `perry/tasks.jsonl`.** Untouched and unread; the PMO owns
+   them. No identifiers were minted.
+6. **`bin/perry-lint`'s 22 fix hints** (§ 10.10). Not re-measured.
+7. **Whether `_root_flag`'s unquoted output breaks on characters other than a
+   space** — quotes, `$`, newlines in a project path. Only the space case was
+   measured.
+8. **`schema/state-schema.json`, `reference/config.md`, `bin/README.md`**
+   beyond reading the diff and the two sentences the CRLF guard pins.
+9. **Anything under `.perry/events.jsonl`.** No write-side Perry tool was run
+   against the repository or any worktree of it. `perry-conform declare` was
+   run **only** inside my own throwaway fixtures under `scratchpad/r4space`,
+   never against Perry. `perry-tasks render --write` was never run anywhere.
+
+---
+
+## 9 · Verdict
+
+**FAIL.**
+
+The round-3 FAIL is genuinely closed: the two refusals carry the caller's root,
+`declare` and `migrate_record` cannot silently inherit an omission, the sweep's
+census reproduces, the end-to-end proof extracts and runs the command rather
+than constructing it, and M35 and M36 — the two the row found GREEN and
+recorded rather than re-pointed quietly — are both red for the stated reason,
+with M36's original surface still covered (R-N7). Six of the row's mutations
+that nobody had ever reproduced are red. The corrected counts (14/16, 4/12) are
+right.
+
+The FAIL is § 1: **the command the refusal hands back is built by unquoted
+string interpolation, so on a project path containing a space the reader who
+copies it gets `rc=1` and a usage error about a file argument they never
+typed** — measured on a planted project, on the sentence this round rewrote, on
+the standard the row states in its own § 1.2. The row's own end-to-end proof
+would catch it if one fixture root had a space in it; `shlex.quote` in
+`_root_flag` closes it in one line.
+
+Four green mutations support the verdict rather than carry it: two of
+`rollback_message`'s three call sites can drop the caller's root undetected
+(§ 2.1), the sweep's ok/bad decision can be disarmed with the suite green
+(§ 2.2), and the restore point's expected-after entry for the legacy record —
+a call this branch added on the recovery path — can be deleted with the whole
+of `tests.test_migrate` green (§ 2.3). Two claims in the RESULT do not survive measurement — M34 is not
+invisible to the helper (§ 3), and § 10.9's *"no root in scope"* is untrue for
+two of the three excused members, where the handed-back command writes to the
+wrong project rather than no-opping (§ 5.3).
+
+---
+
+*checked:* every suite run, mutation and probe was performed in this reviewer's
+own detached worktrees (`scratchpad/r234r4-tip`, `-main`, `-probe`, `-mut`,
+`-mut2`), never in `/Users/bytedance/proj/Perry`. Destructive verification was
+done on planted throwaway projects under `scratchpad/r4space`, never on the
+repository. Every mutated file was restored by exact text with its `md5`
+asserted; one mutation left in place by an external timeout was restored the
+same way and the tree digest re-checked against the pre-mutation value. No
+`git checkout`, `stash`, `reset` or `clean` was run in any tree. No write-side
+Perry tool was run against the project or any worktree of it. No identifiers
+were minted; `perry/BOARD.md` and `perry/tasks.jsonl` were not touched.

+# TASK-234 — V4 review, round 5 (the third layer, looked for and not found)
+
+Subject: branch `coding/task-234-conformance-store`, tip `138ad79` (11 commits
+on `f783dd5`). Base: `main` at **`f5e7a78`**, where it stood for this whole
+round — it did not move while these numbers were taken. Merge probe is
+`f5e7a78` + `138ad79` = **`95fef8d`**, cut and run by this reviewer.
+
+Reviewer worked in its own detached worktrees (`scratchpad/v5-main`, `-tip`,
+`-mut`, `-probe`) and its own branch (`review/task-234-round5`). The project
+under review was never modified; the live checkout at
+`/Users/bytedance/proj/Perry` was read only and is clean at `f5e7a78`.
+Destructive verification was done on throwaway projects this round planted
+under `scratchpad/r5vspace` and `scratchpad/r5vattack`.
+
+**Verdict: PASS.** Rounds 3 and 4 both failed on one sentence of
+`bin/perry-conform:360` — *"a wall — every branch here ends in a command the
+reader can run"* — one register deeper each time. **I went looking for the
+third register with the strongest instrument I could build and there is not
+one.** Every handed-back command in both tools, on every branch I could reach,
+parses, carries the exact root the caller typed, and runs correctly when pasted
+into a real `/bin/sh` on a project path carrying ten shell-hostile characters,
+a state file whose own name carries three of them, and a relative `--root`.
+Findings below are accuracy and coverage, not correctness; the largest is that
+one census number in the RESULT is 50 % too big for the population it names.

+
+## 0 · Baselines, counted the way the runner makes hard, measured this session
+
+Sum of the per-module `FAILED (failures=N)`; `errors=N` summed **separately**,
+because a module can report `FAILED (errors=1)` with no failures and a
+failures-only sum misses it. `grep -c '^FAIL:'` undercounts (`tests/parallel:283`
+truncates a red module's stderr to its last 25 lines with nothing visibly
+elided). The summary line counts MODULES.
+
+```
+grep -oE 'FAILED \(failures=[0-9]+' <log> | grep -oE '[0-9]+$' | paste -sd+ - | bc
+grep -oE 'FAILED \(errors=[0-9]+'   <log> | grep -oE '[0-9]+$' | paste -sd+ - | bc
+```
+
+| tree | modules | tests | seconds | modules red | **failures** | **errors** | `grep -c '^FAIL:'` (the trap) |
+|---|---|---|---|---|---|---|---|
+| `main` @ `f5e7a78` | 105 | 3148 | 273.6 | 3 | **4** | **0** | 3 |
+| tip `138ad79` | 103 | 3150 | 227.6 | 3 | **4** | **0** | 3 |
+| merge probe `f5e7a78` + `138ad79` = `95fef8d` | 105 | 3200 | 244.3 | 3 | **4** | **0** | 3 |
+
+Sequential on one machine, so the seconds are comparable. Red set identical in
+all three, by name: `test_diagnose.py` (failures=2), `test_heading_title.py`
+(1), `test_kr_progress_provenance.py` (1). The merge is clean (no conflicts)
+and introduces no new red. `3148 → 3200` on the probe is **+52**, which is the
+tip's own 3150 − 3124-at-fork plus `main`'s 26 — the row's own arithmetic,
+reproduced.
+
+**`test_host_support` appears in none of the three runs**, so no number here
+depends on the known intermittent being quiet. Recorded rather than netted out.
+
+**md5 bracket** (`git ls-files -z | xargs -0 md5 -q | md5 -q`), before and
+after each suite run, `git status --porcelain` **empty** after each:
+
+| run | before | after |
+|---|---|---|
+| `main` @ `f5e7a78` | `f1d22d04888c206006fa860d492836a3` | `f1d22d04888c206006fa860d492836a3` |
+| tip `138ad79` | `fa525b9964445cbfbd2cc6c8ae8d2b42` | `fa525b9964445cbfbd2cc6c8ae8d2b42` |
+| probe `95fef8d` | `2c5a005939f4b9a5e0805970838550d1` | `2c5a005939f4b9a5e0805970838550d1` |
+
+The last four commits on the branch (`debdee8`, `35e0336`, `1706a0e`,
+`138ad79`) touch **only** `perry/evidence/2026-08/TASK-234-result.md` —
+verified with `git show --stat`. So the row's own runs at `35e0336` and the
+suite at the tip are runs of the same code.
+
+---
+
+## 1 · The third layer — looked for, with what instrument, and not found
+
+Round 3: the command named the wrong project. Round 4: the command named the
+right project in a form that does not parse. Round 5's answer is `_q` plus a
+source rule plus a hostile fixture plus `/bin/sh`. The question this round owes
+is whether there is a fourth thing wrong with the same sentence.
+
+### 1.1 · Every reachable branch, on a real shell, on my own planted projects
+
+I planted throwaway projects under `scratchpad/r5vspace` (never Perry, never a
+worktree of it), drove eight distinct refusal surfaces, extracted every command
+with the **shipped** extractor (`tests/handed_back.py § commands_named`),
+and pasted each into `/bin/sh -c` with only the tool's own name substituted:
+
+| surface | commands | all parse | root exact | `/bin/sh` |
+|---|---|---|---|---|
+| gate refusal, legacy record present | 1 | ✓ | ✓ | rc 0 |
+| gate refusal, conformant-but-undeclared | 4 | ✓ | ✓ | rc 0 ×4 |
+| gate refusal, malformed board | 4 | ✓ | ✓ | rc 0 ×4 |
+| `migrate`, fixed-point refusal | 1 | ✓ | ✓ | rc 1 (record still unfixed — correct) |
+| `migrate`, unreadable-rows refusal | 1 | ✓ | ✓ | rc 1 |
+| `declare` route into the conversion | 1 | ✓ | ✓ | rc 1 |
+| `status` with a legacy record | 2 | ✓ | ✓ | rc 0 (+1 `<file>` placeholder) |
+| `declare` with a refused file | 1 | ✓ | ✓ | rc 1 |
+| `perry-migrate` dry run / apply / `restore --list` | 3 | ✓ | ✓ | rc 0 — **the restore actually ran and put 2 files back** |
+
+Then the whole round trip, end to end, on a project at
+`…/My Project (v2) & 'draft' "q" $x; echo hi #1 *`, standing in a *different*
+Perry project: the refusal hands back
+
+```
+    perry-conform migrate --root '/…/My Project (v2) & '"'"'draft'"'"' "q" $x; echo hi #1 *'
+```
+
+the reader fixes the named lines, pastes that line into `/bin/sh` — **rc 0, one
+declaration carried with its 2026-08-20 date intact, the markdown deleted, and
+the project they were standing in byte-identical.** That is the standard, met.
+
+Two arguments beyond the root also go through `_q` and I exercised both:
+
+* **A state file whose own name is shell-hostile.** `knowledge/research/My
+  Notes & 'draft'.md`. The refusal hands back
+  `perry-conform declare 'knowledge/research/My Notes & '"'"'draft'"'"'.md' --root '…'`
+  and pasting it into `/bin/sh` declares that file, rc 0. (Round 5's own § 1.3
+  says this was handed back raw before — it is not now.)
+* **A relative `--root`.** Typed `--root '../My Project (v2) & …'` from a
+  sibling directory; the refusal hands the relative form back verbatim and it
+  works from the same cwd. This is the payoff of carrying the *typed* root
+  rather than the resolved one, and it is the case a resolved root would have
+  answered differently.
+
+### 1.2 · The two characters the row excludes, measured
+
+**Newline** — the row says this is unmeasured. It is now.
+
+`_q` quotes it correctly. The message becomes two lines, the second
+unindented:
+
+```
+Fix those lines, then run:
+    perry-conform migrate --root '/…/My
+Project'
+**Nothing was written.**
+```
+
+Pasted **whole** into `/bin/sh` this works: rc 0, the reader's project
+converted, `.perry/conformance.jsonl` written. Copying only the indented line
+gives `unexpected EOF while looking for matching '`, rc 2, and
+`commands_named` — being line-based — sees the same truncated half. So the
+declared limitation is real and is *milder* than the RESULT states: the
+sentence "a command carrying one cannot be handed back on a single line at all"
+is true, but the command **is** handed back correctly across two lines and does
+run. The residual is a continuation line that does not look like part of the
+command.
+
+**Backtick** — reproduced exactly as § 10.12 describes on a root
+``/tmp/a `b` c``: the two indented commands parse and carry the root a backtick
+and all; the two inline backticked ones truncate at the reader's backtick and do
+not parse. The framing — *"the break is in the message's markdown, not in the
+quoting"* — is **right**: `_q`'s output is a correct shell word, and what fails
+is the single-backtick delimiter. The pin-that-goes-red-when-closed is the same
+device the row already uses for TASK-246 and is defensible.
+
+**What the framing gets wrong is the size.** § 10.12 says *"two branches of
+`message_for`"*. Resolved off the AST, **eight** handed-back commands in these
+two tools are delimited by inline backticks around an interpolated root:
+
+| site | command |
+|---|---|
+| `bin/perry-conform:460` | `perry-lint{r}` |
+| `bin/perry-conform:460` | `perry-conform declare {_q(v.path)}{r}` |
+| `bin/perry-conform:876` | `perry-conform migrate{_root_flag(root_arg)}` |
+| `bin/perry-conform:890` | `perry-conform declare <file>{_root_flag(root_arg)}` |
+| `bin/perry-conform:961` | `perry-lint{_root_flag(root_arg)}` |
+| `bin/perry-migrate:689` | `perry-goals commit --migrate{_root_flag(root_arg)}` |
+| `bin/perry-migrate:1725` | `perry-tasks render --write{r}` |
+| `bin/perry-migrate:1725` | `perry-tasks write --from-board{r}` |
+
+I ran three of the six that are not in `message_for` on a backtick root and
+watched them truncate: `perry-conform status` prints two, and a refused
+`declare` prints one. `test_a_backtick_in_the_root_is_quoted_and_what_that_costs`
+calls `C.message_for` directly, so **only the first two are pinned**. Two of the
+unpinned six are the `perry-tasks render --write` / `write --from-board` pair
+that § 10.9 is about, and those *write* — so the residual is not uniformly the
+harmless shape the paragraph implies.
+
+Harm requires a backtick in a directory name, so this is a correction to the
+document, not a FAIL.
+
+---
+
+## 2 · Routing around the choke point — 19 spellings, 8 got through
+
+The RESULT's argument (§ 1.3) is that a choke point alone is a convention, and
+that the new part is a source rule that makes the bypass spelling red. I wrote
+19 handed-back commands in a file of my own (`scratchpad/r5vattack/bypass.py`),
+each reaching the message with a shell-unsafe argument, and ran the shipped
+sweep over it.
+
+**11 caught, 8 missed.**
+
+| # | spelling | caught? |
+|---|---|---|
+| B1 | `--root {root_arg}` in the template (control) | ✔ |
+| B2 | `r = " --root " + root_arg`, then `f"…migrate{r}"` | ✘ |
+| B3 | `r = " --root %s" % root_arg` | ✘ |
+| B4 | `r = "".join([" --root ", root_arg])` | ✘ |
+| B5 | `Template(" --root $root").substitute(...)` | ✘ |
+| B6 | `r = " --root {}".format(root_arg)` | ✔ (via the literal `{}`) |
+| B7 | `--root {_passthrough(root_arg)}` | ✔ |
+| B8 | nested f-string `--root {f'{root_arg}'}` | ✔ |
+| B9 | module constant `FLAG = " --root "`, then `FLAG + root_arg` | ✘ |
+| B10 | `r = " --root " + str(root_arg)` — the name the allow-list blesses | ✘ |
+| B11 | `declare {path}{r}` | ✔ |
+| B12 | `"    perry-conform migrate --root %s\n" % root_arg` | ✘ |
+| B13 | the same with `.format(p=…)` | ✔ |
+| B14 | `{root_arg!s}` | ✔ |
+| B15 | short flag `-r {root_arg}` | ✔ (as `no root`) |
+| B16 | `{_q(root_arg)[1:-1]}` | ✔ |
+| B17 | hand-quoted `--root '{root_arg}'` | ✘ |
+| B18 | `{FIXES['legacy']} --root {root_arg}` | ✔ |
+| B19 | `{flag} {root_arg}` | ✔ |
+
+Two shapes are new relative to the fixture's own 19 and both are structural:
+
+1. **Assemble the flag before the template.** `render()` returns `None` for a
+   `BinOp` whose operand is a `Name`, so `" --root " + root_arg` is never
+   examined as a template; the surviving `Constant` `" --root "` has no `{`, so
+   `FLAG_VALUE` cannot fire. The variable is then interpolated into the command
+   phrase, and if it is called `r` — the natural name, and the one this codebase
+   uses — `SAFE_INTERP` blesses it by name. Same for `%`, `str.join`,
+   `string.Template`, and a module constant. `.format` is the exception, and only
+   because its `{}` survives into a literal.
+2. **A literal quote in the template truncates the phrase.** `TAIL` is
+   `[^`\n'"]*`, so `f"perry-conform migrate --root '{root_arg}'"` is read as the
+   phrase `perry-conform migrate --root` — `ROOT` matches the literal `--root`,
+   the interpolation is outside the phrase, and the sweep prints **`ok`**.
+   Hand-quoting is exactly what someone reaching for "fix the quoting" writes,
+   and it breaks on any path containing an apostrophe.
+
+**None of the eight is reachable in the shipped tree.** I checked by AST: no
+handed-back template in either tool contains a literal quote, and no flag value
+is assembled outside a template. So this bounds the guard, it does not indict
+the code. It does mean the RESULT's *"the bypass spelling is not discouraged, it
+is RED"* is true of the spellings the fixture plants and not of the class — which
+§ 10.13 already says in general terms and can now say with two named shapes.
+
+**M42, M43, M44, re-run, whole of `tests.test_conformance` + `tests.test_migrate`:**
+
+| id | result | distinct failing methods |
+|---|---|---|
+| M42 (`_root_flag` interpolates raw) | RED | 24 |
+| M43 (`{v.path}` un-quoted) | RED | **1** — `test_no_refusal…without_the_root` only |
+| M44 (`{tail}` re-glued) | RED | **1** — same |
+
+M43 and M44 are red on the source guard **and nothing else**, exactly as § 6.1
+claims. M42's 24 methods matches the row's own figure.
+
+---
+
+## 3 · The parameter removal — every caller checked, none weakened
+
+Signatures by `inspect`, on the tip:
+
+```
+declare        (…, run: 'str' = '', *, root_arg: 'str | None') -> 'dict'
+migrate_record (project_root: 'Path', *, root_arg: 'str | None') -> 'dict | None'
+plan_project   (project_root, state_root, schema, only=None, *, root_arg: 'str | None') -> 'Plan'
+rollback_message (point, key, why, allow_changed=None, *, root_arg: 'str | None') -> 'str'
+do_restore     (project_root, positional, do_list, as_json, *, root_arg: 'str | None') -> 'int'
+fix_tables     (…, rewritten, *, root_arg: 'str | None') -> 'list[str]'
+migrate_text   (…, mint, *, root_arg: 'str | None') -> 'Edit'
+apply_plan     (plan: 'Plan', schema: 'dict', declare: 'bool' = True) -> 'dict'
+render         (plan: 'Plan', applied: 'dict | None') -> 'None'
+Plan.root_arg  : str | None, NO default
+```
+
+`apply_plan` and `render` genuinely have no root parameter; `Plan.root_arg` has
+no default; `plan_project` requires it keyword-only. The round-4 finding
+(three silent defaults in `bin/perry-migrate`) is closed on all three.
+
+**Callers, enumerated.**
+
+* `apply_plan` — one production caller (`bin/perry-migrate:2295`); nine test
+  call sites. Every one either passes a plan from `Project.plan()` or builds one
+  inline with `root_arg=str(p.root)` — the **hostile** root. None passes `None`.
+* `plan_project` — two production callers (`:2293`, `:2298`), both from `main`
+  with the typed `root_arg`; eight test call sites, all with `root_arg=str(p.root)`.
+* `render` — one production caller (`:2315`). The `M.render(...)` cluster in
+  `tests/test_md_store.py` is a **different** `render` (`bin/perry_md_store.py`),
+  not this one; checked, not assumed.
+* **Nothing is stubbed.** The one test that replaces these functions —
+  `test_apply_plans_and_writes_while_the_project_lock_is_held` — wraps
+  `real_plan` / `real_apply` and delegates, asserting only that the lock is held.
+  `test_migrate.py`'s other monkeypatches replace `write_atomic`, `undo` and
+  `shutil.copy2`, never the three functions under discussion.
+
+**Does `Plan` carry the *typed* root?** Two mutations, whole of both modules:
+
+| id | mutation | result |
+|---|---|---|
+| R5-1 | `plan_project` builds `Plan(…, root_arg=None)` | **RED** (4 methods) |
+| R5-2 | `plan_project` builds `Plan(…, root_arg=str(project_root))` — the **resolved** path instead of the typed string | **RED** (2 methods) |
+
+R5-2 is the one that matters: on this machine `tempfile` roots resolve
+`/var/…` → `/private/var/…`, so the resolved root is a *different string* and
+`assert_every_command_carries`'s parse-and-compare catches it. The claim is
+pinned, not merely written. My relative-`--root` round trip (§ 1.1) is the
+reader-facing reason it should be.
+
+---
+
+## 4 · `tests/handed_back.py`, and assertions that can pass over an empty set
+
+The consolidation is real and the vacuity guard is where it belongs:
+`assert_every_command_carries` opens with `assertTrue(named, …)`, so the M56
+class — a test asserting over an empty extraction — cannot recur at any of its
+seven call sites. Both `_INDENTED` and the sweep's `CUE` are `[ ]{2,}` now, and
+**M56 is red** (reproduced, § 5).
+
+I diffed `tests/` across `f783dd5..138ad79` for removed assertions. The only
+removals are the two `assertIn`/`assertRegex` pairs in `test_migrate.py` that
+were **replaced** by extraction plus `assert_every_command_carries` — a
+strengthening. No assertion was deleted or relaxed.
+
+Four things worth naming, none a defect:
+
+1. **Two hand-written extractors survive beside the shared one**, both in
+   `tests/test_conformance.py`:
+   `test_every_non_conformant_state_names_a_command_that_exists` (line 384,
+   `line.strip().startswith("perry-")`) and
+   `test_a_backtick_in_the_root_is_quoted_and_what_that_costs` (line 2477,
+   `l.startswith("    ")`). The row's own argument — *"the rule lives here so
+   there is one of it"* — is carried out for the root assertion and not for
+   these. Neither is load-bearing about the root; the second is *why* § 1.2's
+   residual is measured on two sites and not eight.
+2. **`test_the_sweep_reports_every_planted_defect_it_claims_to_see` would pass
+   over an empty `regions()`.** Its `assertTrue(found)` guards the sweep's
+   output, not the fixture's inventory: if `regions()` returned `[]` the
+   per-spelling loop would be empty and the test green. It is saved by its
+   sibling `test_the_recall_the_result_quotes_is_the_recall_measured_here`,
+   which pins `(seen, missed) == (18, 1)`. A pair, not a test — worth knowing
+   before either is edited.
+3. **The non-vacuity floor is 20 and the actual count is 21.** One command of
+   slack in `test_no_refusal_in_perry_conform_names_a_command_without_the_root`.
+   Real, but thin.
+4. **Nothing asserts the fixture root is hostile.** See § 6.

+
+## 5 · Mutations — 57/57 reproduced independently, plus 16 of my own
+
+**The row's whole harness, re-run by me**, in `scratchpad/v5-tip`,
+`python3 tests/mutate_task_234.py`: **`57/57 mutations reddened their named
+test`**, no `✗`. Tree digest `fa525b9964445cbfbd2cc6c8ae8d2b42` before and
+after, `git status --porcelain` empty. So `57/57` is now a number two people
+have seen.
+
+**Sixteen of my own**, anchored on exact text with a uniqueness assertion,
+`__pycache__` cleared and the whole-second boundary crossed either side,
+`PYTHONDONTWRITEBYTECODE=1`, **GREEN asserted before mutating**, and **restored
+by writing back `git show HEAD:<file>` — the git object, never bytes my harness
+wrote** — with `git status --porcelain` re-checked empty after each. Target for
+every one: the whole of `tests.test_conformance` + `tests.test_migrate`.
+
+| id | mutation | result | methods |
+|---|---|---|---|
+| M42 | `_root_flag` interpolates the root raw | RED | 24 |
+| M43 | `{v.path}` un-quoted in the STALE branch | RED | 1 (source guard) |
+| M44 | `{tail}` re-glued to the DRIFTED command | RED | 1 (source guard) |
+| R5-1 | `Plan` gets `root_arg=None` | RED | 4 |
+| R5-2 | `Plan` gets the **resolved** root, not the typed one | RED | 2 |
+| R5-3 | `rollback_message` stops quoting the restore-point stem | RED | 1 (source guard) |
+| R5-4 | the `undo with:` line stops quoting the run id | RED | 1 (source guard) |
+| R5-5 | `render`'s `r = _root_flag(None)` | RED | 1 |
+| R5-6 | `see them with \`perry-lint\`` drops the root | RED | 1 (source guard) |
+| R5-7 | the inline `declare` in the errors branch drops the root | RED | 1 (source guard) |
+| R5-8 | the legacy-record branch's `migrate` drops the root | RED | 1 (source guard) |
+| R5-9 | `do_restore`'s listing command drops the root | RED | 2 |
+| R5-10 | `assert_every_command_carries` reverted to round 4's substring rule | RED | 20 |
+| R5-11 | the sweep's `TAIL` stops excluding the backtick | **GREEN — SURVIVOR** | 0 |
+| R5-12 | the sweep's `CUE` loses its indentation branch | RED | 3 |
+| R5-15 | `_q` quotes with **double** quotes, inner quotes escaped | RED | 5 |
+| R5-14 | the fixture root made friendly, alone | GREEN (expected — recorded, § 6) | 0 |
+| R5-16 | the fixture root made friendly **and** round 4's defect put back | RED | **2** |
+
+Six of these are worth a sentence.
+
+**R5-15 is the mutation the RESULT says it could not construct.** § 6.1 ends
+*"I did not construct a mutation caught by only that layer, and say so rather
+than claim one."* Quote with `"` instead of `'` and escape the inner quotes:
+`shlex.split` does not expand `$`, so the parse-based helper reads the exact
+root and **all sixteen invocations stay green**; the source guard stays green
+because `_q` is still called. `/bin/sh` expands the fixture root's `$x` to
+nothing, addresses a path that does not exist, and
+`test_the_named_command_converts_the_readers_project_from_elsewhere` goes red.
+Four incidental exact-text assertions elsewhere also go red (they read
+`perry-conform declare BOARD.md` as a substring, which double-quoting breaks),
+so it is not *uniquely* the shell layer — but it is red on the shell layer and
+**invisible to both of the layers the three-layer argument is about**. The
+`/bin/sh -c` step earns its keep, measured.
+
+**R5-16 is the strongest evidence for the fix's shape, and it is the row's own
+argument confirmed.** Make the fixture root friendly and put round 4's shipped
+defect back: 24 red methods collapse to **2** — and the two that remain are
+`test_no_refusal_in_perry_conform_names_a_command_without_the_root` (the source
+rule, via `FLAG_VALUE`) and `test_a_backtick_in_the_root_is_quoted_and_what_that
+_costs` (which builds its own root and does not use the fixture). So the claim
+that a source rule is needed *because a choke point is a convention* is not an
+argument here, it is a measurement: with every runtime layer disarmed, the
+source rule still catches the round-4 FAIL.
+
+**R5-11 is a survivor and it is the sweep's own ok/bad boundary again.**
+Removing the backtick from `TAIL`'s excluded set — so a phrase runs past its
+closing backtick into the following prose — leaves both modules green. That is
+the same shape as the round-4 reviewer's R-N8 which this round closed for
+`ROOT`, `SAFE_INTERP`, `IS_WHOLLY_A_COMMAND` and `FLAG_VALUE` (M45–M48): the
+*phrase boundary* has no positive control. `tests/fixtures/handed_back_spellings.py`
+is the natural place for one — a planted command followed by prose that would be
+swallowed. Not charged as a defect: the boundary is correct today, and the
+mutation makes the sweep noisier rather than blinder.
+
+**R5-10 is a flawed probe and I say so rather than count it.** I meant to test
+whether the *parse* half of the assertion is load-bearing; what I actually
+measured is that round 4's `assertIn(f"--root {root}", cmd)` is now
+**incompatible** with the corrected output — `_q` emits
+`'…& '"'"'draft'"'"' …'`, which does not contain the raw root as a substring.
+That is a real datum (the two rules are genuinely different, not one weaker than
+the other) but it is not the datum I was after.
+
+---
+
+## 6 · The fixture is the guard, and nothing guards the fixture
+
+`tests/handed_back.py § HOSTILE_ROOT_NAME` is
+`My Project (v2) & 'draft' "q" $x; echo hi #1 *`. Verified character by
+character: space, `(`, `)`, `&`, `'`, `"`, `$`, `;`, `#`, `*` — **ten**
+present; backtick and newline absent, both declared and both measured in § 1.2.
+
+**No fixture quietly uses a friendly root.** Both `Project` classes
+(`tests/test_conformance.py:126`, `tests/test_migrate.py:177`) build under it,
+and `dirname` is never passed by any caller — grepped, not assumed. The three
+other tempdir fixtures in `test_conformance.py` (`copy_of`,
+`TestOneDefinitionOfTheShape`, `TestTheGateSpeaksEveryDocumentLanguage`) do use
+friendly roots and none of them asserts anything about a handed-back command;
+checked one by one.
+
+**But the hostile name is a bare string constant with no assertion on it.**
+R5-14: replace it with `"proj"` and both modules stay green. R5-16: do that
+*and* put round 4's FAIL back, and 24 red signals become 2. So a future edit
+that "tidies" the fixture name — the same instinct that produced
+`tempfile.TemporaryDirectory()` in round 4 — silently disarms twenty-two of the
+twenty-four signals, and the suite says nothing.
+
+This is § 11's own table, one row further on: round 4's entry reads *"the input
+never exercised the failure"*, and the answer was a hostile default in the
+fixture. A hostile default that nothing asserts is a hostile default that can be
+edited back. The exposure is **bounded** — the source guard and the backtick
+test survive it, which is exactly what round 4 did not have — and the fix is one
+line beside the constant, the same shape as
+`assertIn(b"\r\n", …, "the fixture is not CRLF, so this measures nothing")`
+already in `test_a_crlf_record_converts_and_the_wording_does_not_say_byte`.
+
+Recorded, not charged.
+
+---
+
+## 7 · The two claims re-derived
+
+### 7.1 · The CRLF regex — **both halves hold**
+
+I reconstructed the round-4 reviewer's nine plausible overclaims and put them to
+both regexes:
+
+| regex | catches |
+|---|---|
+| round 4's `byte[- ]for[- ]byte(\s+identical)?\s+(to\s+)?what` | **3 / 9** |
+| round 5's widened one | **9 / 9** |
+
+and the **widening that was not taken** (`byte-for-byte` + any short run of
+characters + the object) also catches 9/9 and fires on exactly the two sentences
+the RESULT names, no more:
+
+```
+bin/perry-conform : 'byte-for-byte" was not what'      ← the CORRECTING comment
+bin/README.md     : 'byte for byte **while the file'   ← perry-config's TRUE claim
+```
+
+The shipped regex fires on nothing in either file. The positive pin
+`"ine-for-line, not byte-for-byte"` occurs **exactly once** in each file, so
+M39/M57 are not vacuous. `3/9 → 9/9` and the rejection-on-measurement are both
+correct as written.
+
+### 7.2 · The census outside these two tools — **the defect counts are right, the headline is not**
+
+§ 10.14 prints, under *"The round-5 rule over all twelve other `bin/perry-*`
+tools"*:
+
+```
+63 handed-back command(s), 232 mention(s);
+25 handed back without the caller's root, 19 interpolating a value raw
+```
+
+Re-derived with the shipped sweep over the twelve Python tools that are not
+`perry-conform` or `perry-migrate` (four `bin/perry-*` are shell scripts and the
+sweep cannot parse them):
+
+```
+42 handed-back command(s), 208 mention(s);
+25 handed back without the caller's root, 19 interpolating a value raw
+```
+
+**`63 − 42 = 21` and `232 − 208 = 24` are exactly `bin/perry-conform` +
+`bin/perry-migrate`'s own contribution**, which I measured separately
+(`21 handed-back, 24 mentions, 0 rootless, 0 unquoted`). So the headline pair is
+a count over **fourteen** tools carried into a sentence about **twelve**. The
+population of the follow-on row is **42**, not 63 — the class outside these two
+tools is a third smaller than the document says. The row's own § 11 has a name
+for this: *a number whose subject moved*.
+
+Everything else in the paragraph reproduces exactly:
+
+* **25 rootless**, split `perry-tasks` 11, `perry-task` 9, `perry-decide` 2,
+  `perry-goals` 1, `perry-lint` 1, `perry-state` 1 — confirmed per tool.
+* **19 raw interpolations**, split **3 in a genuine command phrase (all in
+  `bin/perry-task`) / 16 `FLAG_VALUE` in prose** — confirmed by listing them.
+
+One correction inside the correction. Of the three "genuine" ones, **two
+interpolate the command's verb, not an argument**:
+
+```
+bin/perry-task:2307  'perry-tasks {verb}write --from-board'
+bin/perry-task:3859  'perry-task {ʼdoneʼ if want == ʼdoneʼ else ʼdropʼ}'
+```
+
+Neither can carry a space, so neither is the round-4 defect. Only
+`bin/perry-task:734` — `perry-task cadence-done {id} --evidence <path>` — is a
+raw *value*. The genuine count is **1**, not 3, and the over-report rate is
+18/19 rather than 16/19. The paragraph's conclusion (the rule is too blunt to
+extend past these two tools without sharpening) is if anything strengthened.
+
+---
+
+## 8 · What else was checked and holds
+
+* **The sweep over the two tools is at zero on both rulings**, rc 0, and its
+  census over `bin/perry-conform` alone reproduces (14 handed-back / 16
+  mentions / 0 / 0).
+* **`_q` is genuinely the only quoting call.** `shlex.quote` appears in
+  `bin/perry-conform § _q` and nowhere else in `bin/` outside `_q`'s two
+  callers; `bin/perry-migrate § _q` imports it rather than re-typing it.
+* **`root_arg` is the raw typed string.** `main` reads it off `argv` and
+  `_roots()` resolves a *separate* value; the two never cross. Confirmed by
+  reading both `main`s and by R5-2.
+* **The M56 disagreement is closed on both sides.** `_INDENTED` and `CUE` are
+  both `[ ]{2,}`; `do_restore`'s three-space listing is extracted (I saw it come
+  out of a live run) and M56 is red.
+* **No new red at the merge**, and nothing this branch adds trips `main`'s new
+  `tests/test_tree_guard.py`: the probe run is 105 modules with the same three
+  red as `main`, and the tree-guard section reports *"nothing under … moved"* in
+  all three logs.
+* **`perry-conform status`'s `<file>` and `perry-migrate restore <run-id>` are
+  placeholders**, not commands to paste; the sweep's `_ARG` admits `<name>`
+  deliberately. I did not run them and do not count them as defects.
+
+---
+
+## 9 · What I did NOT verify
+
+1. **`bin/perry-lint`'s 22 fix hints** (§ 10.10). Not re-measured, in either
+   round.
+2. **The `_plan_task_store` and `fix_tables` refusals end to end.** Same gap the
+   row declares in § 10.9: the flag is in the template and the template is
+   guarded (M52, M53, R5-6 … all red), but I did not build a project whose task
+   store disagrees with its board, nor one whose `Commitments` table carries the
+   pre-split `By when` column, and read the message off a running tool. I did
+   confirm those two commands truncate on a backtick root (§ 1.2) by reading the
+   template, not by triggering the refusal.
+3. **A `.perry/conformance.md` hand-maintained by anyone but Perry** (§ 10.3).
+   Not sampled by round 3, round 4 or me. Still a substitute.
+4. **The five remaining branches of the backtick residual**, beyond confirming
+   three of them truncate and resolving all eight off the AST.
+5. **`schema/state-schema.json`, `reference/config.md`, `viewer/parsers.py`**
+   beyond reading the diff, the `inspect` signatures, and the mutations above.
+   The 57/57 harness covers `viewer/parsers.py`'s eleven guards; I did not read
+   that file's diff line by line.
+6. **`tests/test_procedures_call_the_tool.py`, `test_one_header_rule.py`,
+   `test_header_index_is_the_only_fold.py`** — touched by the branch, covered
+   only by the suite runs and by M19/M20 in the harness.
+7. **A reader who is not in a Perry project at all** (§ 10.11). Unmeasured here
+   too.
+8. **The board and `perry/tasks.jsonl`.** Untouched and unread; the PMO owns
+   them. No identifiers were minted.
+9. **Anything under `.perry/events.jsonl`.** No write-side Perry tool was run
+   against the repository or any worktree of it. `perry-conform declare` and
+   `perry-migrate apply` were run **only** inside throwaway projects this round
+   planted under `scratchpad/r5vspace`. `perry-tasks render --write` and
+   `perry-tasks --dry-run` were never run anywhere.
+
+---
+
+## 10 · Verdict
+
+**PASS.** This row merges.
+
+The round-4 FAIL is closed and closed at the right level. `_q` is one choke
+point and every argument of every handed-back command in both tools goes
+through it — the root, the file path, the restore-point stem, the run id. The
+source rule reaches the choke point's own body, where no command-phrase rule
+can, and **R5-16 proves it is not decoration**: with the hostile fixture
+disarmed, the source rule is one of only two things left that catch round 4's
+defect. The hostile fixture root carries ten shell-hostile characters, no
+fixture quietly opts out of it, and the end-to-end proof pastes what the
+message printed into a real `/bin/sh` — a layer **R5-15** shows is not
+redundant with the other two.
+
+I went looking for the third register and could not find one. Eight refusal
+surfaces, every command extracted by the shipped extractor and pasted into
+`/bin/sh`, on a hostile project path, on a state file whose own name is
+hostile, and on a relative `--root`: all parse, all name the reader's own
+project, all do what the sentence says. The two excluded characters are
+measured — the newline case works when the whole two-line block is pasted, which
+is better than the document claims, and the backtick case is a markdown
+delimiter problem, correctly diagnosed. `57/57` is reproduced by a second party
+with the tree digest bracketed. The three trees read 4 failures and 0 errors
+with the same three red modules by name, and the merge is clean.
+
+Five things for the record, none blocking, in descending order of how much
+they would cost the next reader:
+
+1. **§ 10.14's headline census is over fourteen tools, not twelve** (§ 7.2).
+   The population of the follow-on row is 42 handed-back commands, not 63. The
+   two defect counts (25, 19) and both splits are right.
+2. **§ 10.12 sizes the backtick residual at two and it is eight** (§ 1.2), of
+   which only the `message_for` pair is pinned, and two of the unpinned six are
+   the commands that write.
+3. **The hostile fixture root has no assertion on it** (§ 6). One line beside
+   the constant would close it, and the row already writes exactly that line for
+   its CRLF fixture.
+4. **The sweep's phrase boundary has no positive control** (R5-11), and eight of
+   nineteen fresh bypass spellings get past the source rule (§ 2) — two of them
+   shapes the fixture does not plant. None is reachable in the shipped tree; the
+   recall number is a bound on a self-chosen population and § 10.13 should say
+   so with those two shapes named.
+5. Of the "3 genuine" raw interpolations outside these tools, **two interpolate
+   a verb rather than an argument** (§ 7.2); the genuine count is 1.
+
+---
+
+*checked:* every suite run, mutation and probe was performed in this reviewer's
+own detached worktrees (`scratchpad/v5-main`, `-tip`, `-mut`, `-probe`), never
+in `/Users/bytedance/proj/Perry`, which is clean at `f5e7a78` and was read
+only. Destructive verification was done on throwaway projects under
+`scratchpad/r5vspace`; the sweep's bypass file lives in `scratchpad/r5vattack`
+and is not in any Perry tree. Every mutated file was restored by writing back
+`git show HEAD:<file>` — the git object, not bytes this harness wrote — with
+`git status --porcelain` re-checked empty and the whole-tree `md5` compared
+against the value taken before the first mutation (`fa525b9964445cbfbd2cc6c8ae8d2b42`, both sides). One mutation pair (R5-16) left a file dirty when its first restore
+asserted cleanliness before the second had run; both files were restored from
+their git objects and the tree digest re-checked before anything else ran. No
+`git checkout`, `stash`, `reset` or `clean` was run in any tree. No write-side
+Perry tool was run against the project or any worktree of it. `perry/BOARD.md`
+and `perry/tasks.jsonl` were not touched and no identifiers were minted.

+## Why this row exists
+
+Measured 2026-08-29 at a30e103. The file is 38 lines: a 10-line prose header that is ALREADY a constant in the writer (bin/perry-conform:406 HEADER) and 24 rows of four regular columns — File, Shape version, Declared, Route — with not one word of per-row prose. render() at bin/perry-conform:423 rebuilds the whole file from the declarations on every write_atomic, so unlike .perry/config.md this one already round-trips from its own records. It has exactly ONE reader (viewer/parsers.py:394 read_conformance, placed there deliberately so lint, conform and any front-end cannot disagree) and ONE writer (bin/perry-conform:474), so the blast radius is two functions rather than a directory. Parsing that table has already cost twice, and both are TASK-050's defect class: parsers.py:415 records its split_row as 'the SIXTH implementation of this, found by a V4 reviewer after five were unified — it reads a row out of a regex group rather than off a line, which is why every sweep looking for strip(|).split(|) at the start of a line walked past it', and the line below it uses squash rather than .lower() because a bolded | **File** | header row was once read as a declaration.

+Blocked until TASK-050 lands: converting this reader removes one of the markdown tables TASK-050's header_index() has to cover, so doing it first means TASK-050 converts a site that is about to be deleted. TWO THINGS TO SETTLE BEFORE WRITING CODE, both real. (1) BOOTSTRAP ORDER: this file gates every write under ADR-004's enforce gate, including the write that migrates it — the migration path must not require the gate to be passable mid-migration. (2) SELF-REFERENCE: schema/state-schema.json:2053 already states, deliberately, that .perry/conformance.md is NOT a files[] entry because 'it is a record of the user's decisions ABOUT state, not state, and listing it here would make it declarable-conformant about itself'. That reasoning carries over to the jsonl unchanged and must be moved across EXPLICITLY, not dropped in the format change. (3) NOTE FOR THE GOALS LANE, not this row's to write: P003-O1-KR1, KR2 and KR3 are all phrased 'of 6' over the six stores in claims[]. A seventh claimed store moves that denominator. Whether conformance.jsonl joins claims[] at all is the same question as (2).

+# TASK-234 — V4 review
+
+# FAIL
+
+One reproducible defect, in code this row shipped, sitting on the row's own
+load-bearing claim: **the one-way door's refusal names a command that tells the
+user nothing, and that command names the door back.** A pre-conversion project
+whose record is not a fixed point has every write path closed and no shipped
+command that will name the offending line.
+
+Everything else in the row verified, most of it independently. This is a narrow
+FAIL on a row that is otherwise the most carefully measured one I have reviewed:
+21/21 mutations reproduced on my own copy, both baselines reproduced within two
+minutes of each other, both `TASK-246`/`TASK-248` verdicts correct, and the
+vacuity finding real and exactly as described.
+
+---
+
+## 1 · The defect
+
+`bin/perry-conform:583` — `migrate_record`'s fixed-point refusal ends:
+
+> Diff it against the record and remove what does not belong:
+>     `perry-conform status`
+> then run `perry-conform migrate` again. **Nothing was written.**
+
+`perry-conform status` performs no diff and reports nothing about the markdown's
+contents. On a pre-conversion project `read_conformance` returns an empty store,
+so `record.unreadable` is `[]` (the rows all *read* fine — the file simply is not
+a fixed point), and the only thing `status` adds is a pointer back to
+`perry-conform migrate` — the command that just refused.
+
+### Reproduction
+
+```

+$ git -C <perry> show 49d83fc:.perry/conformance.md > brick/.perry/conformance.md
+$ printf '\n' >> brick/.perry/conformance.md          # the author's own example: "a stray blank line"

+then run `perry-conform migrate` again. **Nothing was written.**

+```
+
+No surface names the line. Measured across every read command and both output
+modes:
+
+```
+$ { perry-conform status; perry-conform migrate; perry-conform declare BOARD.md;
+    perry-lint; } --root . 2>&1 | grep -nE "line [0-9]+|:38"

+```
+
+### Why this is a defect and not a nit
+
+- **Every write path on the project is closed.** `perry-conform declare` calls
+  `migrate_record` first (`bin/perry-conform:630`) and raises; `perry-migrate
+  apply` refuses and rolls back (the M21 path); `perry-task` / `perry-goals` /
+  `perry_md_store` all refuse at the gate because the store does not exist.
+  Reading works. Nothing writes until a human finds the byte by eye.
+- **It contradicts the file's own written standard**, in the function directly
+  above the one that ships the message. `message_for`'s docstring:
+  *"A gate that says 'not conformant' and stops is a wall — every branch here
+  ends in a command the reader can run."* And `DEFAULT_MODE`'s comment: *"a
+  refusal that names a command nobody can run is the wall ADR-004 § 4 forbids"*
+  — the argument that held the enforcing default back for a whole release. This
+  new refusal surface shipped without the guard the project applies to its
+  other refusals: `test_every_non_conformant_state_names_a_command_that_exists`
+  covers `message_for`'s verdict states, not `migrate_record`'s, and
+  `assert_conversion_refuses` asserts only `"refused" in out`.
+- **The instruction is not merely unhelpful, it is false about what the named
+  command does.** "Diff it against the record" describes a diff `status` does
+  not compute.
+- **It is reachable by ordinary editing.** I measured nine plausible hand edits
+  to Perry's own 23-row record against `migrate_record` (script:
+  `scratchpad/rv234-handedit.py`):
+
+  | edit | outcome |
+  |---|---|
+  | untouched | accepts, 23 declarations |
+  | a row deleted — *the act the record's own header invites* | **accepts**, 22 |
+  | two rows swapped | refuses |
+  | a trailing blank line | refuses |
+  | no trailing newline | refuses |
+  | one trailing space on a row | refuses |
+  | a `>` note appended | refuses |
+  | an HTML comment above the rows | refuses |
+  | one cell re-padded | refuses |
+  | CRLF line endings | accepts (see § 6) |
+
+  The documented act survives, which is a real mitigation. Seven of nine other
+  ordinary edits do not.
+- **The fix is small and in scope.** `render_legacy(record.declarations)` is
+  already computed on the refusing line; `difflib.unified_diff` against `text`
+  would name the first divergence. Or `status` learns the fixed-point check for
+  a legacy record and reports it, which is what its message already implies.
+
+No open board row covers this (`perry/tasks.jsonl` grepped for `conform` /
+`refus`); it is new with this row.
+
+---
+
+## 2 · The one-way-door argument — ruled on
+
+The author's framing: *"that is the whole-file fixed point TASK-241 round 2
+rejected AS A READING RULE, correct here for the reason it was wrong there."*
+
+**The distinction is genuine, and it is not the same failure wearing a hat.**
+Three things carry it:
+
+1. **The cost function really is different.** A reading rule runs on every write
+   and a false negative is permanent and recurring — one stray line voids all 23
+   declarations at every future call. A conversion runs once and fails closed:
+   nothing written, markdown intact, store absent
+   (`assert_conversion_refuses` asserts all four).
+2. **The fixed point buys a property the round trip cannot have, by
+   construction.** A canonical row inside `<pre>` / an HTML comment /
+   `<details>` is byte-for-byte a genuine row; no predicate over the row sees
+   it. I confirmed the reader honours all three
+   (`read_legacy_conformance` → `["BOARD.md"], 0 unreadable`) and the conversion
+   refuses all three. **M9** (delete the fixed point) reddens exactly that test.
+3. **The two layers are independently load-bearing, measured not argued.**
+   `test_an_asterisked_path_reads_exactly_as_it_did_before` plants a row that
+   *is* a whole-file fixed point, so only the round trip stands between it and a
+   real key; **M20** (delete the round trip) reddens
+   `test_a_backticked_path_cell_is_not_a_declaration` while the fixed point is
+   intact. Both reproduced on my copy.
+
+**But the argument's stated premise is not delivered.** The author's own words:
+*"the cost of refusing is* look at your file*."* Measured, the cost is *look at
+37 lines by eye, with no tool help, while every write on the project is
+refused.* The architecture is right; the mitigation it depends on was not built.
+That is the whole of the FAIL.
+
+---
+
+## 3 · The two rows — both verdicts confirmed
+
+### `TASK-248` — **DISSOLVED. I agree.**
+
+- **Structural, for the store.** One JSON object per line; there is no block
+  construct for a row to hide inside. A line prefixed or wrapped by anything is
+  not valid JSON and is `unreadable`.
+- **The laundering half is gone.** `render()` was deleted. `render_legacy` is
+  referenced at exactly one site — `bin/perry-conform:581`, the right-hand side
+  of the comparison. Both `write_atomic` calls in the file
+  (`:597`, `:662`) write `P.render_conformance(...)`, the store. Nothing writes
+  a markdown row, so nothing can launder one into a canonical one.
+- **The one surviving reachable path is the conversion, and it is shut.**
+  `read_legacy_conformance` has exactly one production caller
+  (`bin/perry-conform:571`); everything else naming it is a test. The three HTML
+  spellings are asserted separately and the test states out loud that the reader
+  *does* honour the row — which is what makes the file-level check load-bearing
+  rather than belt-and-braces.
+
+### `TASK-246` — **NOT dissolved. I agree, and the pin is sound.**
+
+Read from the code, not the account: `declare()` (`bin/perry-conform:662`)
+writes `P.render_conformance(record.declarations)` — the *parsed* declarations.
+`record.unreadable` is never carried forward and nothing reports it at the
+moment of destruction. Identical mechanism to the markdown writer; only the
+population of unreadable lines shrank.
+
+**The pin is not vacuous**, which was the thing to check. It has its own
+control: it first asserts `len(read_conformance(...).unreadable) == 1` (so a
+reader that stopped reading fails there), then asserts `rc == 0` (so a refusal
+fails there), and only then asserts the bad line is gone. If TASK-246 is fixed
+the third assertion goes red; if the fixture rots the first two go red. It
+carries its own instruction for that day. Ran green on the shipped tree.
+
+---
+
+## 4 · Claims 1–3
+
+**Claim 1 — bootstrap and self-reference are one decision, ungated by
+construction. Verified independently.** I enumerated every `gate()` call site
+in the repository myself, not from the test:
+
+| site | key passed | can it be the record? |
+|---|---|---|
+| `bin/perry-task:7194` | `GATED_FILE = "BOARD.md"` (`:6750`), a constant | no |
+| `bin/perry-goals:3251` | `GATED_FILE`, or `register_path()` → `phase/<NNN>-linkage.md` | no |
+| `bin/perry_md_store.py:1157` | `doc.rel_file` — a markdown `Doc` under the state root | no |
+
+Three sites, all in `bin/`; nothing in `viewer/`, `packs/`, `setup/`, `modes/`.
+`gate()` → `verdict()` → `spec_for()` → `state_files()`, which enumerates
+`schema/state-schema.json § files[]`; neither `.perry/conformance.jsonl` nor
+`.perry/conformance.md` is a `files[]` entry (checked in the JSON). So the
+record's write is ungated because it is not schema-claimed state, not because
+anything exempts it. No exemption is granted and none is needed. Correct.
+
+**`test_no_writer_gates_on_the_record` cannot pass vacuously.** It carries an
+anti-vacuity control — `assertIn("BOARD.md", keys, "the fixture yields no files
+at all")` — before the two `assertNotIn`s, so a `state_files()` that returned
+nothing fails first. It then asserts `verdict(<record>).state == ABSENT`.
+
+**Claim 2 — `claims[]` answered separately, no entry of its own. Verified, with
+one small note.** 6 claimed `.jsonl` stores excluding the event log
+(`.perry/config.jsonl`, `asks/intake/okr/risks/tasks.jsonl`); `.perry/` is a
+claimed dir; the three `"6 of 6"` KRs are live in
+`perry/phase/003-linkage.md:11,18,25`. The tripwire **does** fire — I added a
+seventh store to a copy's schema:
+
+```
+AssertionError: 7 != 6 : the number of claimed stores moved to 7 ([...]);
+perry/phase/003-linkage.md's KR1, KR2 and KR3 are each phrased 'of 6' and are
+now wrong
+```
+
+*Note:* for the one scenario the tripwire was written for — adding
+`.perry/conformance.jsonl` itself — the earlier `assertNotIn(CONFORMANCE_FILE,
+claimed)` short-circuits, so the test is red but the failure message does not
+name the KRs. Both orderings are red; only one of them tells the goals lane
+what it needs. Worth one line of reordering, not a blocker.
+
+**Claim 3 — no read-time fallback; the refusal names `migrate`, not `declare`.
+Verified, and I rule the distinction sound.** `read_conformance` sets
+`rec.legacy` and returns; it never parses the markdown. M7 (reintroduce the
+fallback) reddens `test_the_markdown_alone_declares_nothing`; M15 reddens the
+refusal branch. The legacy branch is first in `message_for` (`bin/perry-conform:400`).
+
+**On `SKILL.md:197`:** `migrate` is not the act that line reserves. The act
+reserved is *the user declaring that a file matches Perry's shape*. `migrate`
+writes `render_conformance(read_legacy_conformance(file).declarations)` — the
+parsed record and nothing else. It cannot add a key, and the whole-file fixed
+point means it cannot even carry a key the record did not honestly hold.
+Measured by `test_the_conversion_declares_nothing_the_record_did_not_hold`, and
+provenance stays `""` on every converted row rather than stamping the
+conversion's own clock onto a decision made on 2026-08-20. An agent running
+`migrate` transcribes; it does not decide. I concur, and no `perry-conform
+declare` was run anywhere in this review.
+
+---
+
+## 5 · The 69 tests, the 17, and the vacuity finding
+
+**Spot-checked the 17.** They did not quietly stop testing what they were for.
+Each keeps its planted shape, its layer-1 assertion on
+`read_legacy_conformance` (unchanged from TASK-241 — I diffed the function body
+against `49d83fc:viewer/parsers.py § read_conformance` and it is verbatim modulo
+the docstring and two renamed constants), and gains `assert_conversion_refuses`,
+which asserts exit code, `"refused"` in the payload, the store **not** written,
+the markdown **not** deleted, and the verdict still `undeclared`. The class-level
+control `assert_trap_would_have_worked` is real and runs first in eleven of them:
+it plants the undecorated row and requires it to read as a declaration *and*
+convert cleanly at `rc == 0`, so none of the seventeen can pass because the
+reader stopped reading. The remaining six carry inner controls instead — the
+HTML test asserts the reader **honours** the row before asserting the conversion
+refuses it, which is the strongest form of the pattern in the file.
+
+Two changed their expected outcome (`..._is_not_laundered_by_the_next_declare`
+now assert the declare *refuses*) and say so in the body, including the
+assertion that the other file is not half-declared on top of an unconverted
+record. Stated, not buried. Correct.
+
+**The vacuity finding is real, and I reproduced it exactly.** Pointing
+`TestTheFifthCopy.probe` back at `read_conformance` and removing the new assert:
+
+```
+read_conformance ->     ([], [])
+read_legacy_conformance -> (['BOARD.md'], [])
+$ python3 -m unittest tests.test_one_header_rule.TestTheFifthCopy
+Ran 2 tests ... OK
+```
+
+Green over nothing to nothing, exactly as described. With the reader repointed
+away but the new assert kept, it fails loudly:
+
+```
+AssertionError: read_legacy_conformance returned nothing at all for a record it
+should read — the comparisons in this class would be vacuous
+```
+
+And M19 shows the class is now load-bearing. Confirmed vacuous before, not now.
+
+The 8 rewritten tests are honest translations — the property is identical, the
+assertion moved off row text onto the parsed record. One latent fragility worth
+naming: `p.line().replace('"shape_version": 2', ...)` hard-codes the current
+shape version, so a version bump turns the mutation into a no-op — but the
+resulting test then *fails* (`len(unreadable) == 1` becomes 0) rather than
+passing wrongly, so it is fail-safe.
+
+---
+
+## 6 · Mutations — 21/21 reproduced independently
+
+Ran `tests/mutate_task_234.py` on my own clean archive of `3e11697` (never in
+the reviewed worktree). **21/21 reddened their named test**, and
+`diff -r` against a pristine archive afterwards is empty — the harness restores
+byte-for-byte. The harness itself is sound: unique-anchor assertion, GREEN-first
+assertion, `__pycache__` clearing and whole-second sleeps, md5 restore check,
+and it refuses a dirty tree.
+
+**M11 — hand-verified, and the harm is exactly as claimed.** I weakened the
+guard on a copy (`if store.exists() or not legacy.exists():` →
+`if not legacy.exists():`), gave a project a live store holding two hand-written
+declarations, and dropped a one-row markdown beside it:
+
+```
+=== MUTATED ===
+store after: {"path": "BOARD.md", "declared": "2026-08-20", "route": "migrate",
+              "writer": "", "recorded_at": "", "run": ""}      # OKR.md GONE
+markdown:    conformance.jsonl                                  # deleted
+
+=== SHIPPED ===
+perry-conform: nothing to convert — .perry/conformance.jsonl is already this
+project's record (or it has none).
+store after: both declarations, dates and provenance intact
+markdown:    conformance.jsonl  conformance.md                  # untouched
+```
+
+A stale markdown restored from a backup rolls a live store back and deletes
+itself. Found by mutation, real, fixed.
+
+**M21 — hand-verified against the pre-fix commit.** I archived `fccce1c` (the
+commit before the fix) and ran `perry-migrate apply` on a project with a row
+inside an HTML comment:
+
+```
+=== fccce1c (before) ===
+Traceback (most recent call last):
+  File ".../bin/perry-migrate", line 1900, in apply_plan
+    out = C.declare(...)
+  File ".../bin/perry-conform", line 582, in migrate_record
+    raise LegacyRecordRefused(
+perry_conform.LegacyRecordRefused: .perry/conformance.md is not byte-for-byte...
+                                                        [exit 1, no rollback named]
+
+=== 3e11697 (after) ===
+perry-migrate: refused — ... The run was rolled back — 3 file(s) restored.
+Nothing on disk changed.
+Restore point: .../.perry/migrate/2026-08-30-095403.json
+Recover at any time with:
+    perry-migrate restore 2026-08-30-095403                [exit 1]
+```
+
+Site 3's documented failure mode verbatim, made reachable by this row, caught by
+mutation, fixed, and pinned by a test that asserts both `perry-migrate restore`
+in the message and no `Traceback` on stderr.
+
+Also spot-checked M7, M9, M15, M19, M20 by reasoning through the code path
+before running them; all consistent.
+
+**TASK-209's guard — reproduced.** Moving the entry point back above § 12 on a
+copy:
+
+```
+$ python3 tests/test_conformance.py
+Ran 70 tests in 53.691s
+OK
+$ python3 -m unittest tests.test_claims.TestNoTestFileEndsEarly
+AssertionError: '19' != '15' : test_conformance.py: the file defines 19 TestCase
+classes but only 15 existed when unittest.main() ran — running the file directly
+skips the rest and still reports OK
+```
+
+Exactly the numbers the RESULT claims. The shipped tree has the entry point last.
+
+### Guards that survive their own deletion
+
+I mutated seven guards the harness does *not* cover, running the whole
+`tests.test_conformance` module (not one named test) against each. Five survive:
+
+| | mutation | held? |
+|---|---|---|
+| X1 | `_declaration_from`'s `path` presence/type check → `if False:` | **no test** |
+| X2 | `_declaration_from`'s `declared`/`route` type check → `if False:` | **no test** |
+| X3 | `render_conformance`'s `sorted(...)` → reversed insertion order | **no test** |
+| X4 | `declaration_line`'s field order swapped | red ✓ |
+| X5 | `migrate`'s "takes no file" refusal → accept and ignore | **no test** |
+| X6 | the provenance `isinstance(..., str)` coercion → raw `rec.get` | **no test** |
+| X7 | the M11 condition split into two equivalent `if`s (a no-op control) | green, as expected ✓ |
+
+I traced each of the five: none can produce a false `conformant` verdict or
+destroy data. A pathless or wrong-typed-`declared` line becomes a declaration
+keyed on `None` / `""` that no `state_files()` key ever matches (inert, the
+`**BOARD.md**` case); unsorted output only changes diff noise; the ignored
+argument changes nothing because the conversion is whole-record either way.
+They are defensive branches and cosmetics, not holes. Reported rather than
+waved through because the row's own standard is that a guard nobody can delete
+is not a guard.
+
+---
+
+## 7 · Baselines — reproduced, measured 2 seconds apart
+
+Not in the reviewed worktree: two clean `git archive` extractions run
+concurrently, started `09:47:51` and `09:47:53`, `bash tests/run`, same machine,
+same interpreter.
+
+| tree | result |
+|---|---|
+| `49d83fc` (`main`, fork point) | **103 modules · 3098 tests · 4 failures** |
+| `3e11697` (branch HEAD) | **103 modules · 3123 tests · 4 failures** |
+
+**Same four, diffed by name, not counted:**
+`test_diagnose.TestUserLoadFindings.test_perry_itself_passes_its_own_id_checks`,
+`test_diagnose … test_the_queue_register_reconciles_with_the_queue_on_this_repository`,
+`test_heading_title.PerrysOwnHeadingTitles.test_none_of_them_contains_its_own_id`,
+`test_kr_progress_provenance.TestBothOfTodaysWrongReadingsFlip.test_no_current_in_the_payload_claims_to_be_a_measurement`.
+No new failure. The RESULT's own count (2 in `test_diagnose`, 1 in
+`test_heading_title`, 1 in `test_kr_progress_provenance`) is right; the sentence
+naming them scrambles one — it attributes
+`test_no_current_in_the_payload_claims_to_be_a_measurement` to `test_diagnose.py`
+when it lives in `test_kr_progress_provenance.py`, and does not name the
+queue-register failure. Cosmetic; the numbers are correct.
+
+**The reviewed worktree was never run in.** `md5` of the four files `tests/run`
+writes, taken before my first command and after my last: identical, and
+`git status --porcelain` empty throughout.
+
+---
+
+## 8 · The schema note-edit — ruled on
+
+**A note-only edit to the claim surface does not need the same ceremony as a
+claim change, and this one was handled correctly.**
+
+`git diff 49d83fc 3e11697 -- schema/state-schema.json` is **one line**: the
+`Conformance gate` setting's `note` string. No path was added to or removed
+from `claims[]` or `files[]` — verified by parsing both revisions, not by
+reading the diff (`claims` 24 entries both sides, `files` unchanged, and neither
+conformance name appears in `files[]`).
+
+The reason is in `.perry/hook.md:31` itself: *"**The claim surface** — `claims`,
+`state-schema.json`, **anything that changes which paths Perry writes into
+someone else's project**."* The backticked fragments are what the dispatch
+scanner matches; the prose is the rule they encode, and the rule is about paths.
+A `note` string changes no path, occupies no territory, and cannot move a
+denominator. The gate is a *dispatch-time* scan of a spec's `Files in scope`,
+not a post-hoc audit of a diff, so the correct handling is exactly what
+happened: flag it in the RESULT so a reviewer checks the diff, and let the
+reviewer confirm no path moved. Flagging it was right; requiring a second
+sign-off for it would train the next author to reword the spec instead, which is
+`TASK-107`'s own lesson.
+
+---
+
+## 9 · What I could not check
+
+1. **No second real project could be converted.** `~/proj/gimegime-pmo` exists
+   but has **no conformance record at all** — its `.perry/` holds only
+   `config.md` and `hook.md`. I swept every project on this machine
+   (`~/proj/*/.perry`): `PolyForge` has only `diagnose/`, `aimark` and
+   `data-algo` have `config.md`. `find ~/proj -name conformance.md` outside
+   Perry returns nothing. **No hand-maintained record exists locally to sample.**
+   The author's § 10.3 caveat stands unresolved and is not his to resolve.
+
+   *Substituted, and named as a substitute:* the only real corpus available is
+   the git history of Perry's own record. All five committed versions
+   (`9143b13` 13 declarations, `c1ac067` 16, `2e41336` 24, `0179c02` 23,
+   `49d83fc` 23) are fixed points with 0 unreadable rows — including
+   `c1ac067`, a *docs* commit. Plus the nine-case hand-edit sweep in § 1. This
+   samples "written by Perry over months", not "hand-maintained over months".
+
+2. **`"byte-for-byte" is an overstatement, benignly.** Both sides of the
+   comparison go through `Path.read_text()`, which applies universal-newline
+   translation, so a CRLF record converts and the docstring's "byte-for-byte" is
+   really "text-for-text after newline normalisation". Nothing can be laundered
+   by it — the reader and the comparison see the same normalised text, so the
+   invariant *the file as read is exactly what `render_legacy` would write* still
+   holds — and accepting a Windows checkout is arguably the right behaviour.
+   Prose, not code.
+
+3. **I did not re-derive the "44 pass unchanged" list** test by test; I read the
+   full `tests/test_conformance.py` diff and confirmed that the only test bodies
+   it touches are the 8 named in § 4.2 plus the 17 in § 4.3, which is the same
+   claim from the other side.
+
+4. **I did not audit `perry-migrate`'s restore path end to end** beyond the M17
+   and M18 mutations and the M21 reproduction above.
+
+---
+
+## 10 · To clear the FAIL
+
+One change, and it is small: make the fixed-point refusal name the divergence.
+`render_legacy(record.declarations)` is already in hand at
+`bin/perry-conform:581`; a `difflib.unified_diff` against `text`, truncated to
+the first few hunks, turns the refusal into the thing the message already claims
+it is. Optionally teach `perry-conform status` the same check for a legacy
+record, since that is the command the refusal names. Then add the assertion the
+row's other refusals already carry — `assert_conversion_refuses` should require
+the message to name the line, the way
+`test_every_non_conformant_state_names_a_command_that_exists` requires a runnable
+command — so the guard cannot be deleted with the suite unchanged.
+
+Nothing else in this row needs to move.
+
+---

+`conformance` keys and the contract goes to `perry-decide/list/2.0` (§ 4).
+The human-readable `list` output now prints `missing_type` and
+`off_enum_status`, which were reachable only through `--json` — it used to
+print the two index divergences and nothing else, and dropping half a payload
+on the surface that is now the only surface is the same defect one layer up.
+
+**`viewer/parsers.py`** — the reader. `parse_decisions(text)` parsed the
+`## Active` table of the index; it now takes the state root and reads
+`decisions/ADR-*.md`. **This one was mandatory, not tidying**: leaving it would
+have made `perry-state`'s `decisions.count` zero on every project forever,
+which is verbatim the defect `bin/perry-decide`'s own docstring says the tool
+was built to end. Verified equal, field by field, against the old reader on the
+old file — § 7 A.
+
+**Schema and contracts.** `claims[path=DECISIONS.md]` and
+`files[id=decisions]` removed from `schema/state-schema.json`; the
+`.perry/conformance.md` declaration row removed;
+`schema/decide-list-contract.md` rewritten and given a `2.0` changelog row.
+
+**Docs.** `SKILL.md`, `decide/SKILL.md`, `decide/reference/decisions.md`,
+`work/SKILL.md` and four `work/reference/` pages, `goals/SKILL.md` and two
+`goals/reference/` pages, four root `reference/` pages, `bin/README.md`,
+`packs/software-ops/architecture.md`, both READMEs, and the two `work/state/`
+templates now name `decisions/` or `perry-decide list`.
+
+**No replacement index, under any name.** DESIGN-013 § 4.1 says the markdown
+link surface into `decisions/ADR-*.md` is given up and that the implementing
+row must not quietly re-add it. `tests/test_decide_writer.py §
+TestNothingWritesAnIndex` is that sentence as a test, and it is written as
+*"after this command the only files that exist are ADR bodies"* rather than
+`assertFalse(DECISIONS.md.exists())` — a guard shaped round one filename is
+satisfied by `ADRS.md`. Mutation 4 in § 6 plants exactly that and it goes red.
+
+## 2 · Finding 1 — two tools disagree about whether an id can be reissued
+
+**The most important thing this row produced, and it is DECLARED, not fixed.**
+Somebody other than me should decide whether it is acceptable.
+
+**`perry-decide` reissues a deleted ADR number. `perry-task purge` does not.**
+An ADR id is an address — `perry/evidence/`, `perry/design/` and the ADR
+bodies cite each other by it — so a reissued number means **two different
+decisions can share one address**, and a citation written before the delete
+resolves to the decision written after it. Nothing in the tree detects that.
+Measured, not reasoned:
+
+```
+$ perry-decide bootstrap --root .          # creates decisions/ only
+$ for i in 1..10: perry-decide new …       # ADR-001 … ADR-010
+$ perry-decide new eleven --title Eleven --type Process
+perry-decide: wrote ADR-011
+$ ls DECISIONS.md
+ls: DECISIONS.md: No such file or directory     ← minted with the index absent
+$ rm decisions/ADR-011-eleven.md
+$ perry-decide new twelve --title Twelve --type Process
+perry-decide: wrote ADR-011                     ← REISSUED
+```
+
+**The disagreement is between two tools over one contract**, and the contract
+is `perry-task`'s: *an id, once issued, is never issued again.*
+`bin/perry-task § minting_records` states it — *"a purged number is retired,
+not freed"* — and gives the reason in the same breath: `.perry/events.jsonl`
+is append-only and still carries the dead record's `add`, `drop` and `purge`,
+so a new row wearing that number would inherit a timeline that is not its own.
+Every word of that applies to an ADR except the mechanism.
+
+**`perry-decide` cannot follow that rule today and TASK-235 does not make it.**
+The rule needs an append-only log and this lane writes no events at all — there
+is no `.perry/events.jsonl` line with `perry-decide` on it. Retiring an ADR
+number means teaching the lane to write events first, which is a lane-shaped
+change and its own row. The exposure is smaller than `perry-task`'s: there is
+no `perry-decide purge`, so an ADR leaves `decisions/` only when a human
+deletes the file, and nothing resolves ADR ids against a log. **That is a
+reason it can wait, not a reason it is acceptable** — that call is not mine to
+make and this row does not make it. It is now *stated* — in
+`mint_id`'s docstring and in
+`tests/test_decide_writer.py §
+TestMintingReadsTheFilesAlone.test_a_deleted_adr_number_is_reissued_and_that_disagrees_with_purge`,
+whose failure message says what to change and where if this ever becomes false.
+
+## 3 · Finding 2 — TASK-214 is closed, and the defect was larger than filed
+
+**Nothing survives.** There is no index; `mint_id` reads `read_adrs` and
+returns. TASK-214 as filed is closed by this change.
+
+**The row under-described its own defect, and that is the part worth keeping.**
+It reads as *"the departed half erases itself"* — a redundant source going
+quiet. What was there was worse: **reissue was NON-DETERMINISTIC.** The union
+`max(files ∪ index)` gave a deleted id exactly one command of memory, because
+the very next write re-rendered the index *from the files* and dropped the row
+that was holding the number. So whether a deleted id came back depended on
+**how many unrelated writes happened in between**. Nobody looking at a project
+could say which case they were in, and the same sequence with one extra
+`status` flip in it gives the opposite answer.
+
+Reproduction, on `main`'s `bin/perry-decide` at `ee0b36a`, in a throwaway
+project:
+
+```
+files: ADR-001 … ADR-010, ADR-012, ADR-013
+$ rm decisions/ADR-013-thirteen.md
+index still names ADR-013?  1
+$ perry-decide status ADR-001 --status archived    # an UNRELATED write
+after that write, index names ADR-013?  0          # render_index rebuilt it
+$ perry-decide new fourteen --title Fourteen --type Process
+perry-decide: wrote ADR-013                        ← REISSUED anyway
+```
+
+So `main` reissued too — it just needed one more command to do it. After this
+change the behaviour is one thing, always, and § 2 names what that one thing
+is. A row that closes by showing the defect was bigger than filed is worth
+more than one that closes by meeting its own description, which is why this
+paragraph is here and not only in the commit message.
+
+**A second thing closed on the way, which TASK-214 did not name.** `cmd_new`
+stamps `> Status: active` into every ADR it writes, and nothing bound that
+literal to `enums.decision_status`. The refusal that existed came from
+`render_index` asking `statuses()` for its count line — an accident of the
+renderer, and deleting the renderer took it. `bin/perry-decide § BORN_STATUS`
+is that binding stated where the value is written; mutation 7 in § 6 proves it.
+
+## 4 · The contract: `perry-decide/list/2.0`
+
+`conformance` loses `index_present`, `indexed_without_file` and
+`filed_without_index_row`. Each compared `DECISIONS.md` against `decisions/`;
+with one side of every comparison deleted they could only report a constant,
+and a conformance field that cannot vary reads to a consumer as a check being
+performed.
+
+`schema/decide-list-contract.md § Adding a status is not a break` names the
+break in the contract's own words — *"renaming or removing a key, or narrowing
+a documented field"* — so this is a **major**, and the changelog carries a
+`2.0` row saying what a consumer of the three should read instead.
+
+Two baselines had to move with it and **neither was regenerated wholesale**:
+
+- `tests/fixtures/contract-shapes.json` — only the `perry-decide/list` entry
+  was spliced. Keys gone: the three. Keys added: `semantics` (TASK-205's
+  addition, which the fixture had never been re-recorded for). No type moved.
+- `tests/fixtures/contract-key-parity.json` — only the `perry-decide/list`
+  entry, re-keyed `1.1` → `2.0`. **A `--record` was run and then discarded**:
+  it also rewrote `perry-task/list/1.18`'s `emitted` from 126 to 115 and
+  populated its `not_observable`, drift no test in that module asserts on. That
+  is a finding for someone else's row (§ 8) and absorbing it here would have
+  been the golden-file regeneration `test_contract_invariance`'s own docstring
+  refuses.
+
+`test_contract_invariance § test_the_major_version_did_not_move` compares the
+recorded major against the live one, so re-recording is the only way to get it
+green after a legitimate bump — and re-recording is exactly what that module
+says must not be how a break is absorbed. So the bump got a door that a
+re-record cannot open: **`test_the_shipped_version_is_recorded_in_its_own_changelog`**
+requires the version a tool ships to appear in its own contract page's
+Changelog. It is standing rather than transitional — it fires on every run for
+all three contracts, not only across the bump — and mutation 9 in § 6 proves it.
+
+## 5 · Finding 3 — `viewer/parsers.py` had to change, and the hunks, for `coding/task-050-header-index`
+
+**Why it was mandatory rather than tidying.** `load_snapshot` read
+`DECISIONS.md` and parsed its `## Active` table into `snap.adrs`.
+`bin/perry-state` builds `decisions.count`, `decisions.last` and
+`expired_sunsets` from that list. Delete the file and leave the reader, and
+every project reports `decisions.count = 0` forever — **which is verbatim the
+defect `bin/perry-decide`'s own module docstring says the tool was built to
+end.** It would have been a silent zero, not an error: the exact "a check that
+cannot fail on the thing it names" shape this project has caught six times.
+Mutation 8 in § 6 is that regression, planted, and three modules go red.
+
+**Exactly what moved. Three hunks, and the big one is a whole-section
+replacement rather than edits inside it:**
+
+| Hunk | Old | New | What |
+|---|---|---|---|
+| `@@ -2550,50 +2550,129 @@` | the `# ── DECISIONS.md ──` section: `parse_decisions(text)` **only** | `# ── decisions/ADR-*.md ──` section: `ADR_ID_RE`, `adr_header_fields(text)`, `read_adr_records(state_root)`, `parse_decisions(state_root)` | the section is replaced whole |
+| `@@ -3860,7 +3939,6 @@` | `decisions_text = read(root / "DECISIONS.md")` | *(line removed)* | one deletion in `load_snapshot` |
+| `@@ -3934,7 +4012,7 @@` | `adrs=parse_decisions(decisions_text) if decisions_text else []` | `adrs=parse_decisions(root)` | one line, `load_snapshot` |
+
+Nothing else in the file is touched: `parse_board`, `parse_okr`,
+`parse_phase`, `parse_linkage`, `parse_top_risks`, `walk_*`, `split_row`'s
+callers and `resolve_state_root` are byte-identical to `main`.
+
+**The one place it can collide with TASK-050, and how to resolve it.** The
+deleted `parse_decisions` contained exactly two header/table call sites —
+
+```python
+in_active = heading_is(line[3:].strip(), "Active")     # old line 2562
+cells = split_row(line)                                # old line 2572
+```
+
+— and **both are inside the replaced section**. If `coding/task-050-header-index`
+converted either of them among its 16 header sites, that conversion is moot
+here: **take the deletion.** The new reader parses `> Key: value` frontmatter
+and has **zero** `heading_is`, `split_row` or header-normalization calls
+(grepped, § 6 F). TASK-050's other sites are in functions this branch does not
+touch, so the rest of that branch merges clean. The two `load_snapshot` hunks
+are single lines and will not conflict unless TASK-050 also edits
+`load_snapshot`'s local reads.
+
+**Why the reader moved down here instead of staying in `bin/perry-decide`.**
+`perry-decide` carried a tolerant ADR-header parser while `parsers.py` carried
+a table parser for the *rendering* of the same records — one record, two
+readers, bound by nothing. With the table gone I could have left a copy in
+each. `split_row` reached **six** implementations before TASK-234 found the
+last one; this is the same defect caught at two. `bin/perry-decide` now does
+`read_adrs = P.read_adr_records` and carries no parser of its own.
+
+## 6 · Mutations

+`__pycache__` cleared, 1.2 s past the whole-second boundary either way,
+restored with an `md5` check that printed `OK`. Harness:

+
+### 6.1 · Three of the nine go red ALONE, and one of them is the whole decision
+
+Mutations **3, 4 and 9** each go red with **exactly one** failing test in the
+whole suite. That is the answer to *"a guard that can be deleted with the suite
+unchanged is not a guard"*: delete any of those three and nothing else in
+~2,900 tests notices the defect it names.
+
+**Mutation 4 is the one that keeps the decision honest after I am gone.** It
+re-adds the index as **`ADRS.md`** — a different filename, same artefact — and
+the test that catches it is:
+
+> `tests/test_decide_writer.py §
+> TestNothingWritesAnIndex.test_status_writes_no_index`
+
+with the message it printed under mutation:
+
+```
+after `status` the decide lane left ['ADRS.md']. Its whole record is
+`decisions/ADR-*.md`; DESIGN-013 § 4.1 forbids re-adding an index under
+any name.
+```
+
+**Its known limit, found by the V4 reviewer and recorded rather than patched.**
+The reviewer could not defeat this guard with any `ADRS.md`-class name, but did
+build one escape: a real index table written as **`decisions/ADR-000-index.md`**.
+That path *is* an ADR body by the guard's own definition, so it slips past
+`TestNothingWritesAnIndex` — and then dies one module over in
+`test_decide_status_enum`, because `read_adr_records` globs it back as an ADR
+and the reader reports it. So the escape is caught, just not here.
+
+**I am not widening the guard to cover it, deliberately.** The predicate that
+would catch `ADR-000-index.md` has to distinguish an ADR body from a table
+inside `decisions/`, which means teaching this guard to parse content instead
+of listing paths — and a guard that parses is a guard that argues about what it
+parsed. The clean statement stays: everything under `decisions/` is an ADR
+body, and anything that is not one is somebody writing a file this lane does
+not own, which the reader already reports.
+
+DESIGN-013 § 4.1 accepts the loss of the web link surface **and warns in the
+same paragraph that the implementing row must not quietly re-add an index to
+avoid it**. A guard written the obvious way —
+`assertFalse((root / "DECISIONS.md").exists())` — is satisfied by `ADRS.md`,
+`INDEX.md` or `decisions/README.md`, so it would have permitted exactly the
+move the design forbids. `TestNothingWritesAnIndex` instead asserts the
+**complete set of files each write command may leave behind** (ADR bodies, and
+nothing else), which is why it names no filename and catches all of them. Its
+five members cover `bootstrap`, `new`, `new --supersedes`, `supersede` and
+`status` — every command in the tool that writes.
+
+## 7 · Findings
+
+**A · The index was not a pure projection in every project, and DESIGN-013
+§ 5.3's "Nothing is lost by deleting it" is true of Perry and not in general.**
+For Perry's own record it is exactly true — the old index reader and the new
+file reader were run side by side over `perry/decisions/` and returned the same
+ten ADRs with the same id, title, type, date and path. The single difference:
+`sunset_or_notes` was `"—"` and is now `""`, because the em dash was the
+*rendering's* placeholder for empty and the old parser read it back as data.
+Nothing consumes that field except `perry-state § expired_sunsets`, where
+`days_since` returns `None` for both.
+
+But `tests/fixtures/sample-project`'s ADR files carried **only** `> Status:
+active` — their `Type`, `Date` and sunset lived in the index and nowhere else,
+and `tests/fixtures/sample-project-zh` had an index and **no `decisions/`
+directory at all**. Deleting the file would have destroyed those fields. I
+rebuilt the ADR bodies from the index rows before deleting (the fixtures now
+model a project whose files are the record), but **for a real project in the
+same state there is no migration step and nothing warns.** `perry-decide`
+always rendered the index from the files, so a project that only ever used the
+tool is safe; a project that hand-edited it (which its own header forbade) or
+adopted Perry through `decide/reference/decisions.md § Migration` can be in the
+fixtures' state. That is a row, not something to fix here.
+
+**B · `perry-decide` no longer takes an ADR-004 conformance gate, and that is a
+loss rather than a simplification.** `DECISIONS.md` was the only file this tool
+wrote that `schema/state-schema.json § files[]` gives a shape. `decisions/ADR-*.md`
+has no `files[]` entry and never had one, so `perry-conform.verdict` returns
+`absent` for it and `absent` passes — a gate on it could not fire, which this
+project removes on sight. A gate on `design/*.md` would be a gate on a file
+this tool does not write, which `bin/perry-goals § main` names as the mistake in
+so many words. So the gate is removed and named rather than faked. Restoring it
+means giving `decisions/ADR-*.md` a `files[]` shape — new claim surface, its own
+row, and `.perry/hook.md` calls that a high-stakes operation.
+
+**How big the loss is, measured — because I first wrote it down smaller than it
+is.** The comment in `bin/perry-decide` used to close *"only the index write
+was ever gated"*. That is **false**, and a V4 reviewer caught it by measuring
+rather than reading. The gate ran *before* the command, so it refused the whole
+command. With `PERRY_CONFORMANCE=enforce` and nothing declared:
+
+| Tree | `perry-decide new` | ADR body written |
+|---|---|---|
+| `main` at `ee0b36a` | **rc=1**, *"DECISIONS.md already matches Perry's shape at version 2, but no one has declared it"* | **none** |
+| this branch | **rc=0** | `ADR-001` |
+
+There is no reachable state on `main` where a body was written past the gate.
+**The decide lane went from fully gated to not gated at all**, and the
+follow-up row should be sized as restoring a gate, not as closing a gap that
+was mostly already open. (My own first attempt to check this reproduced the
+reviewer's claim as false — because I ran `main`'s script with the *branch's*
+`PERRY_HOME`, so it read the branch schema, found no `files[id=decisions]`, and
+returned `absent`. The fixture was wrong, not the reviewer. Recorded because a
+mixed-tree `PERRY_HOME` is a silent way to measure the wrong thing.)
+
+Two consequences already visible in the suite: `test_conformance`'s
+per-file-not-per-project test was written on `perry-decide`/`DECISIONS.md` and
+is now written on `perry-goals`/`OKR.md`, and its § 8
+(*"a file that does not exist yet is not a stranger's file"*) had used
+`perry-decide bootstrap` as **the one shipped case of a tool creating the very
+file it gated on**. There is no stand-in — `perry-task` refuses on a missing
+board, `perry-goals link` on a missing register, `perry-goals commit` on a
+missing `OKR.md` — so those two now call `verdict`/`gate` directly. The property
+survives; the end-to-end delivery of it does not.
+
+**C · The web link surface is gone and nothing replaces it, exactly as
+DESIGN-013 § 4.1 accepts.** A reader browsing this repository lands in
+`perry/decisions/` and reads a directory listing of ten filenames, which do
+carry the slug. What is lost is status, type, date and the active/historical
+split at a glance. I did not re-add an index and I am not recommending one —
+recording it because § 4.1 asks for it to be reported if it matters.
+
+**D · A content grep cannot see a file NAMED `DECISIONS.md`.** Four fixture
+indexes and two shipped scaffolds were invisible to `grep -rn 'DECISIONS.md'`
+because nothing inside them contains the string. `find . -name 'DECISIONS*'`
+found them. The V4 check as written would have passed over the fixtures.
+
+**G · `main` moved while this branch was open, and both overlapping files
+merge clean.** The fork point is `ee0b36a`; `main` is now `7f934d5` (TASK-095
+round 6, TASK-050 round 8 evidence, TASK-203 round 4, and a dispatch record).
+Two files are touched by both: `bin/perry-diagnose` — mine at `@@ -129` and
+`@@ -920`, main's at `@@ -1596`, `@@ -1903`, `@@ -2143`, `@@ -2189` — and
+`bin/perry-goals` — mine at `@@ -52` and `@@ -613`, main's at `@@ -2161` and
+`@@ -2172`. No hunk overlaps. This branch is **61 files, +1505 / -800 against
+its fork point**; measured with `git diff $(git merge-base main HEAD)..HEAD`,
+because `git diff main..HEAD` now reports 72 files and counts other people's
+work as deletions.
+
+**F · The new ADR reader parses no tables and no headings**, which is what
+makes § 5's merge advice safe to act on. Grepped over the replaced section of
+`viewer/parsers.py` at `0179c02`: zero `heading_is`, zero `split_row`, zero
+header-normalization calls. The old `parse_decisions` had one of the first two
+each. So this branch **removes** two header sites from that file and adds none.
+
+**E · `tests/fixtures/contract-key-parity.json` has drifted from live on
+`perry-task/list/1.18`** in fields no test in that module asserts — `emitted`
+126 vs 115, and `not_observable` empty vs five `tasks[].depends_on_resolved[]`
+keys. Not mine, not touched, reported.

+**Measured, on the committed tree, twice independently.** The expectation this
+section used to record is now a measurement:
+
+| Tree | Runner | Result |
+|---|---|---|
+| this branch at `0926e97`, quiet machine | `bash tests/run` (V4 reviewer) | **98 modules · 2892 tests · 458.4s · 3 failures** |
+| this branch at `0926e97`, load ~50 | `python3 tests/parallel -j 4` (me) | **98 modules · 2892 tests · 613.6s · 3 failures** |
+
+Both runs give the **same three failures**, and all three are pre-existing at
+`ee0b36a`: the two in `test_diagnose` and the one in
+`test_kr_progress_provenance` listed above. Steps 1, 3 and 4 of `tests/run`
+were run separately on the committed tree and pass: the template drift guard is
+clean, every `bin/` script parses and answers `--help`, and both sample
+projects lint at **0 errors** (`exit 0` for each).
+
+`2892 − 2882 = +10` is this branch's net test count, and it is now a measured
+delta rather than an arithmetic claim.
+
+**The full-suite run that caught a defect of mine.** `bash tests/run` completed at
+**98 modules · 2892 tests · 594.6s**, with **4 failures across 3 modules**: the
+three pre-existing ones above, plus
+`test_procedures_call_the_tool.test_no_procedure_hand_edits_a_tool_owned_file`
+— **which was mine.** Trimming `SKILL.md` back under its 20,480-byte cap had
+put a write verb inside the guard's 60-character window before the
+`OKR.md § Commitments` target, making `SKILL.md:75` an R1 finding. The guard
+was right and the sentence was wrong; `b57a34a` fixes it, and candidate
+wordings were run through `test_procedures_call_the_tool.scan` directly rather
+than reworded until the suite went quiet.
+
+That run predates the fix, so it is not the number for this tree; the two runs
+in the table above are. The +10 is nine tests added — five in
+`TestNothingWritesAnIndex`, two in `TestMintingReadsTheFilesAlone`,
+`test_the_three_index_keys_are_gone_and_stay_gone`,
+`test_bootstrap_creates_the_directory_and_no_file`,
+`test_a_project_that_never_bootstrapped_lists_cleanly_too`,
+`test_the_status_a_new_adr_is_born_with_is_one_the_schema_declares`,
+`test_the_shipped_version_is_recorded_in_its_own_changelog` — against two
+removed with the index they tested
+(`test_an_index_row_with_no_file_is_reported`,
+`test_a_project_with_no_proposal_renders_no_proposed_section`), plus the
+subTest arithmetic in the two rewritten fixtures.
+
+## 9 · What I did not do, and what I could not verify
+
+- **`unittest discover` was not run**, on either tree. The machine carried
+  several other agents' full suites throughout — load average **32–48**,
+  measured repeatedly — and `bash tests/run` took 576 s at baseline, 763 s
+  mid-change and 595 s on the run that caught the `SKILL.md` defect. The row's
+  brief says that runner shows 3 more failures from a module-double-import
+  artefact in `test_risks_store`; I did not confirm that on this tree and am
+  not reporting it as if I had.
+- **The gap this section declared is now CLOSED, by two runs.** It read: *a
+  clean full run on the committed tree did not finish under load.* The V4
+  reviewer ran `bash tests/run` on `0926e97` on a quiet machine
+  (**2892 tests / 3 failures / 458.4 s**) and my own
+  `python3 tests/parallel -j 4` on the same tree agrees
+  (**2892 / 3 / 613.6 s**). Steps 1, 3 and 4 were run separately and pass.
+  § 8.1 carries both. Kept here rather than deleted because a gap that was
+  declared and then closed is a different record from one that was never
+  there — and because the thing that closed it was somebody else re-running
+  what I could not.
+- **`viewer/parsers.py` is on another agent's list and I edited it anyway.**
+  Reported here as the brief asks. The edit is contained — the
+  `# ── DECISIONS.md ──` section is replaced by a `# ── decisions/ADR-*.md ──`
+  section, and two lines in `load_state` — but it is not small, because the
+  tolerant ADR header reader moved down into it from `bin/perry-decide` rather
+  than being copied. Leaving a copy in each would have been the second
+  implementation of one reader, which is the defect `split_row` reached six
+  copies of before TASK-234 found the last one. **`bin/perry-goals` also has two
+  lines changed** (one docstring sentence, one dead `HANDOFF` key); both are
+  one-word removals of `DECISIONS.md` and neither touches behaviour.
+  `bin/perry-task`, `bin/perry-state` and `bin/perry-conform` are untouched.
+- **`grep -rn 'DECISIONS.md'` does not return zero over `bin/`, `tests/`,
+  `schema/`, `reference/`, `templates/` and the `SKILL.md`s.** It returns 47,
+  and every one is deliberate. By category: my own explanatory notes recording
+  what was deleted and why (`bin/perry-decide` 6, `bin/README.md` 6,
+  `schema/decide-list-contract.md` 3, `viewer/parsers.py` 3,
+  `tests/test_decide_writer.py` 3, and one each in `test_contract_invariance`,
+  `test_row_integrity`, `test_i18n`); historical narrative in test docstrings
+  about defects that happened (`tests/test_ownership.py` 8,
+  `test_procedures_call_the_tool.py` 2, `test_conformance.py` 2); and
+  **foreign-project references, which are live and correct** —
+  `bin/perry-diagnose`'s `DECISION_NAMES` and its `FIT-02` / `TRK-04`
+  prescriptions (4), `reference/project-archetypes.md`'s three-file floor (2),
+  `templates/{ops,software}/{AGENTS,STATE}.md` (4),
+  `tests/test_diagnose.py`'s foreign fixtures (3),
+  `decide/reference/decisions.md § Migration: old monolithic DECISIONS.md`,
+  and one fixture filename in `test_heading_defines.py`. The foreign ones are
+  correct under DESIGN-013 § 5.1 itself: a project with no store has no schema,
+  so a document is where its decisions belong. `bin/perry-diagnose` and
+  `reference/project-archetypes.md` now say so in place, so the next reader
+  does not "fix" them.
+- **`.perry/events.jsonl`, `perry/BOARD.md` and `perry/tasks.jsonl` still name
+  the file and I did not touch them** — the PMO owns those.
+- **I did not update the board or `perry/tasks.jsonl`.**
+- **The `bin/README.md` conformance transcript is kept verbatim as history.** It
+  was measured on 2026-08-20 against `perry-decide bootstrap`, whose gate this
+  row removed, so those exact commands cannot be re-run. I first restated it
+  against `perry-goals` and reverted that: a measurement quoted against a
+  command that can no longer produce it is a measurement nobody took. It is
+  labelled as history and the property it demonstrates is the gate's.
+- **There is no viewer HTML to verify, and I originally listed this as a gap
+  before checking.** `viewer/` contains `parsers.py` and `tables.py` and
+  nothing else — no template, no HTML. `snap.adrs` is consumed by
+  `bin/perry-state` (`decisions.count` / `last` / `expired_sunsets`, all
+  checked against the pre-change reader field by field) and by a `__main__`
+  print in `parsers.py`. `sunset_or_notes` has **no** consumer anywhere, which
+  is why its `"—"` → `""` change in § 7 A is inert.

+# TASK-235 — `DECISIONS.md` stops existing; `perry-decide list` is the surface
+
+> DESIGN-013 step 1, User Decision 3, answered 2026-08-29: **delete it**.
+> The design is locked: `perry/design/DESIGN-013-one-place-per-fact.md`.
+
+## Measured, 2026-08-29 at `30cc467`
+
+`perry/DECISIONS.md` is 1,834 bytes — **76% inside table rows**, 12 rows, longest
+cell 68 bytes. There is no per-row prose. Its own third line already says what it
+is:
+
+> Rendered by `bin/perry-decide` from `decisions/ADR-*.md`. Those files are the
+> record; this file is a view of them. Edit an ADR, then re-run `perry-decide
+> list` to refresh — do not hand-edit rows here, they are overwritten.
+
+`perry-decide list` already prints the same content. One reader, one writer.
+
+## The rule this serves
+
+DESIGN-013 § 5.1, adopted as User Decision 1:
+
+> A fact that has a schema lives in exactly one store. A document holds what has
+> no schema. No field lives in both.
+
+The ADR bodies under `decisions/` are the record. `DECISIONS.md` is a second copy
+of their id, title, type, date and status.
+
+## Deliverable
+
+`perry/DECISIONS.md` is deleted and `bin/perry-decide` no longer writes it.
+`perry-decide list` is the documented surface. Every live reference to the file —
+`SKILL.md`, `decide/SKILL.md`, `schema/`, `reference/` — names the command
+instead. Its `claims[]` entry in `schema/state-schema.json` is removed, and its
+declaration row in `.perry/conformance.md` goes with it.
+
+### `mint_id` — TASK-214 is inside this change, not beside it
+
+`perry-decide`'s `mint_id` reads `max(files ∪ index)` while `render_index`
+rebuilds the index from the files, so the departed half erases itself — that is
+`TASK-214`, and it is now blocked on this row because **deleting the index
+changes its shape**. After this change `mint_id` must read the ADR **files
+alone**. Verify that it does, and that minting is still monotonic across a
+delete: mint `ADR-011`, remove its file, mint again, and confirm `011` is **not**
+reissued if that is the contract — or state plainly that it is, because
+`perry-task purge`'s own rule is that the log keeps an id so it is never
+reissued, and `perry-decide` should not silently disagree with it.
+
+Report whether `TASK-214` is closed by this change or whether something survives.
+
+## Verification — V4
+
+1. `perry-decide list` prints every ADR the deleted file listed, with the same
+   status counts — **10 active / 10 total** at `ADR-010`.
+2. `grep -rn 'DECISIONS.md'` over `bin/`, `tests/`, `schema/`, `reference/`,
+   `templates/` and every `SKILL.md` returns **zero live references**. Matches
+   under `perry/evidence`, `perry/journal`, `perry/design` and `perry/decisions`
+   are the historical record and **stay** — do not rewrite them.
+3. `perry-lint` is at 0 errors and does not report a missing claimed file.
+4. `mint_id` reads the files alone, proved by minting with the index absent.
+5. **Mutation**: restore the writer and show a NAMED test goes red. A guard that
+   can be deleted with the suite unchanged does not count — `perry-goals`
+   shipped exactly such a tautology under TASK-095 and it was removed for it.
+6. `bash tests/run` at the baseline of the commit the work forks from, named by
+   **runner and tree**. `main` at `ee0b36a` is 98 modules / 2882 tests / 3
+   failures under `tests/run`; `unittest discover` shows 3 more from a
+   module-double-import artefact in `test_risks_store`.
+
+## Out of scope, and this one is a decision rather than an omission
+
+**Do not add any replacement index file.** DESIGN-013 § 4.1 records that the
+markdown link surface into `decisions/ADR-*.md` is **given up** by this decision —
+a web reader lands in the directory listing, and `perry-decide list` is a
+terminal surface that cannot be linked to. The draft recommended keeping a
+rendered view and that recommendation was declined by the user.
+
+If the loss turns out to matter, that is a **finding to report**, not a thing to
+quietly fix by re-adding an index under another name.
+
+Also out: `OKR.md` (TASK-236) and `BOARD.md` (TASK-237). Same design, later steps.

+# TASK-235 — V4 review, round 1
+
+**PASS**, with one required correction before merge: a load-bearing code comment
+in `bin/perry-decide` states something about the removed ADR-004 gate that is
+measurably false, and it understates a real safety loss. Nothing about the
+behaviour, the tests, the record or the contract is wrong.
+
+Reviewed at `0926e97`, tip of `coding/task-235-decisions-index`, in a detached
+read-only worktree. Every destructive probe ran against `git archive` copies of
+`HEAD` and of `main` under `scratchpad/rjv235/`, never against the reviewed tree.
+All harness files are prefixed `rjv235-`.
+
+Graded against `perry/evidence/2026-08/TASK-235-spec.md` — **which is not on this
+branch.** It was committed to `main` after the fork point `ee0b36a`, so it was
+read with `git show main:…`. The branch is not missing anything; noting it so the
+next reader does not repeat the search.
+
+---
+
+## 1 · The declared gap is closed. I ran the full suite on a quiet machine.
+
+```
+$ cd <worktree>            # 0926e97
+$ bash tests/run
+1. schema drift guard … ✓ clean
+98 modules · 2892 tests · 458.4s · 8 workers
+✗ 2 module(s) red
+```
+
+**3 failures, and all three are the pre-existing ones the author named at
+`ee0b36a`:**
+
+| Module | Test | Signature |
+|---|---|---|
+| `test_diagnose` | `…test_the_queue_register_reconciles_with_the_queue_on_this_repository` | `2 != 0` |
+| `test_diagnose` | `TestUserLoadFindings.test_perry_itself_passes_its_own_id_checks` | `['ACTION-7','D009-1','D010-2','PROJ-003','SPEC-007']` |
+| `test_kr_progress_provenance` | `…test_no_current_in_the_payload_claims_to_be_a_measurement` | `the register carries no asserted current` |
+
+**Ruling on § 8.1's expectation: it was right.** 2892 tests is the measured
+number, `2892 − 2882 = +10` is the measured delta, and the failure set is
+identical to the fork point's. `test_procedures_call_the_tool` is green, so
+`b57a34a` holds. The author was correct to label it an expectation; it is now a
+measurement.
+
+**Board state for these numbers.** Taken on the branch's own tree, whose
+`perry/BOARD.md` / `perry/tasks.jsonl` are `ee0b36a`'s (§ 9: the author did not
+touch them). On that board `test_contract_key_parity` is **green** — the two
+data-dependent witness tests the brief warns about did not fire, because
+`conformance.in_progress_with_no_live_run` is empty on this board. So the
+baseline here is **3, not 5**, and the difference from the brief's `main` figure
+is board state, not code. `main` has since moved to `208e0d3`, whose own commit
+subject says the two extra failures there are not a regression.
+
+Machine: load average 7.5 at launch, one other agent's suite in flight
+(`scratchpad/rv8-main-6c0d041`). 458s wall, vs the author's 595s under load 32–51.
+
+`perry-lint` on the tree: **0 errors**, 4 pre-existing `NS-01` warnings, and no
+missing-claimed-file report. Spec verification item 3 satisfied.
+
+---
+
+## 2 · The thing most likely to be wrong: there is no replacement index, and the guard is real
+
+**Searched the branch for a replacement index under any name and found none.**
+
+- `git diff --diff-filter=A ee0b36a..HEAD` adds exactly three files: the result
+  doc and two zh fixture ADR bodies. No index was added under any name.
+- `bin/perry-decide` has exactly two write sites: `:379` (the ADR body in
+  `cmd_new`) and `:403` (`_flip` rewriting an ADR body). `render_index` and
+  `index_rows` are gone.
+- `find . -name 'DECISIONS*'` returns only `templates/{ops,software}/DECISIONS.md`
+  — both **unmodified by this branch** and both an append-only *prose journal*
+  for a foreign project with no store, not an index of ADR files. Correct under
+  DESIGN-013 § 5.1, and `bin/perry-diagnose:129` now says so in place.
+- The doc diff consistently says the index is gone; nothing instructs a human or
+  an agent to maintain a substitute.
+
+**The guard has the property claimed.** `TestNothingWritesAnIndex.assert_only_adr_bodies`
+computes `Project.files()` — `root.rglob("*")`, every file at any depth — and
+asserts every entry other than `.perry/config.md` matches
+`^decisions/ADR-\d+-[^/]+\.md$`. It names no filename, so `assertFalse(DECISIONS.md.exists())`'s
+hole is genuinely closed. Its five members cover every write command the tool has.
+
+### I tried to defeat it. Two attempts.
+
+**Attempt 1 — an index under a name the test does not anticipate.** Mutation 4's
+`ADRS.md` is caught (below). So are `INDEX.md`, `decisions/README.md`,
+`decisions/index.md`, `.perry/anything.md` — the regex rejects every one of them
+and `rglob` sees every depth.
+
+**Attempt 2 — an index disguised as an ADR body**, i.e. a real rendered index
+table written to `decisions/ADR-000-index.md`, which *does* satisfy the regex.
+This is the only escape from `TestNothingWritesAnIndex` I could construct, and it
+**escapes that guard** — `test_decide_writer` stays green. It does not survive
+the suite: `test_decide_status_enum` goes red with 3 failures, because
+`read_adr_records` globs `ADR-*.md` and reads the fake back as an ADR, corrupting
+the status counts. So the writer side is sealed by the guard and the reader
+together, and I could not get an index through.
+
+**Residual hole, reported not fixed:** the guard covers `bin/perry-decide`'s
+write commands only. Nothing prevents a *hand-committed* index appearing in
+`perry/decisions/` in a future session. `test_ownership.test_decisions_specifically_is_owned_by_decide_everywhere`
+now carries an explicit `assertNotIn("DECISIONS.md", claims)` with a DESIGN-013
+§ 4.1 message, which covers the schema half. That is the right amount of guard
+for this row; naming it so nobody assumes more.
+
+---
+
+## 3 · Claims, each with a measurement
+
+### Claim 1 — `perry-decide list` prints every ADR, same counts ✅
+
+`python3 bin/perry-decide list --root .` prints ADR-001…ADR-010, all `active`,
+with the same types, and `10 active · 10 total`. The deleted file's header said
+`Active: 10`. `--json` additionally carries `date`, `path`, `deciders`,
+`supersedes`, `lines` — a superset of every column the index had. Nothing lost.
+
+Nit, not a defect: the *human* render prints id/status/type/title and the count
+line but not `date`, and never printed `expired_sunsets`. Both were already true
+on `main`, so no regression — but `perry-decide list` is now the only surface, so
+"the terminal drops half its payload" (the author's own words about
+`missing_type`) still applies to `expired_sunsets`.
+
+### Claim 2 — grep, and the historical record ✅
+
+`grep -rn 'DECISIONS.md' bin/ tests/ schema/ reference/ templates/ SKILL.md */SKILL.md`
+returns **47**, matching § 9's count, and I checked the categories: foreign-project
+detection (`perry-diagnose DECISION_NAMES`, `project-archetypes.md`,
+`templates/*`), historical narrative in test docstrings, and the author's own
+"what was deleted and why" notes. No live self-reference.
+
+**The record is intact, and this is the check that mattered most.**
+`git diff --name-status ee0b36a..HEAD` touches `perry/` in exactly two ways:
+`D perry/DECISIONS.md` and `A perry/evidence/2026-08/TASK-235-result.md`. **Zero
+modifications under `perry/journal/`, `perry/design/`, `perry/decisions/` or any
+existing `perry/evidence/` file.** Nothing was rewritten.
+
+### Claim 3 — `mint_id` reads the ADR files alone ✅
+
+On a throwaway project against the branch tree: `bootstrap` writes `decisions/`
+and nothing else; ten `new` calls mint ADR-001…010 with `find . -type f` showing
+no index at any point; the eleventh mints `ADR-011`. Minting with the index
+absent, proved.
+
+### Claim 4 — THE CONTRACT FINDING. Reproduced, and I rule it acceptable. ✅
+
+Reproduced verbatim on the branch:
+
+```
+$ ls DECISIONS.md            → No such file or directory
+$ rm decisions/ADR-011-eleven.md
+$ perry-decide new twelve --title Twelve --type Process
+perry-decide: wrote ADR-011                     ← REISSUED
+```
+
+**Ruling: "declared and pinned" is an acceptable close, and the framing that it
+"made ADR deletion ordinary" does not survive measurement.** Four grounds:
+
+1. **This row does not introduce reissue.** `main` reissues too (claim 5). What
+   changed is determinism, and determinism is strictly better than a coin flip.
+2. **This row adds no deletion path.** There is no `perry-decide purge`. An ADR
+   leaves `decisions/` only when a human runs `rm`. Deletion is exactly as
+   ordinary as it was.
+3. **The detector that went was not a detector.** I measured what `main` had:
+   ```
+   MAIN, immediately after rm ADR-003:   indexed_without_file = ['ADR-003']
+   MAIN, after ONE unrelated write:      indexed_without_file = []
+   ```
+   The signal had a one-command half-life. Removing a check that erases itself is
+   this project's own house rule, not a loss.
+4. **The fix genuinely needs a different lane shape.** `perry-task`'s rule rests
+   on `.perry/events.jsonl`; `perry-decide` writes no events at all. Teaching it
+   to is a row, not a hunk.
+
+The pin — `test_a_deleted_adr_number_is_reissued_and_that_disagrees_with_purge` —
+asserts the behaviour as it is and its failure message tells the next person what
+to change and where. That is the correct shape for a declared disagreement.
+
+**Condition on the PMO, not on the author:** § 9 says the board was not touched,
+so neither the id-retirement row nor the gate-restoration row (§ 5 below) exists
+anywhere except in prose. Both must be filed on merge or the declaration
+evaporates.
+
+### Claim 5 — TASK-214 was larger than filed. Reproduced on `main`. ✅
+
+This is the strongest thing in the row and it holds exactly:
+
+```
+# main @ 208e0d3, throwaway project, ADR-001…013
+$ rm decisions/ADR-013-d13.md
+index still names ADR-013? 1
+### WITHOUT an intervening write
+$ perry-decide new fourteen …   → wrote ADR-014        (number remembered)
+
+### WITH one UNRELATED write
+$ perry-decide status ADR-001 --status archived
+after an UNRELATED status flip, index names ADR-013? 0
+$ perry-decide new fourteen …   → wrote ADR-013        ← REISSUED
+```
+
+Same starting state, opposite outcome, decided by an unrelated command. Reissue
+on `main` was **non-deterministic**, not self-erasing. TASK-214 as filed described
+a smaller defect than the one that was there, and this row closes the real one.
+
+### Claim 6 — nine mutations. I ran **all nine**, not four. ✅
+
+Every anchor line matched the author's table byte-for-byte before mutation
+(`bin/perry-decide` 107/254/288/345/379/418/435/457, `viewer/parsers.py:2671`).
+Every restore verified by `md5`. Run against a copy.

+Exactly one test in ~2,900 notices an index re-added under a different filename.
+The claim is true, and mutation 9 is notable for the same reason: `2.0 → 2.1`
+does **not** trip `test_the_major_version_did_not_move`, so the new standing
+changelog test really is the only door, and a `--record` cannot open it.
+
+### Claim 7 — `viewer/parsers.py`, and the merge advice for `coding/task-050-header-index` ✅
+
+- **Three hunks, exactly as tabled**: `@@ -2550,50 +2550,129 @@`,
+  `@@ -3860,7 +3939,6 @@`, `@@ -3934,7 +4012,7 @@`. Nothing else in the file
+  differs from `ee0b36a`.
+- **Zero header/table calls added.** Every `heading_is` / `split_row` occurrence
+  on a `+` line is inside a comment. The removed `parse_decisions` contained
+  exactly two live sites — `heading_is(line[3:].strip(), "Active")` and
+  `cells = split_row(line)` — and both are inside the replaced section.
+- **So this branch removes two header sites from `viewer/parsers.py` and adds
+  none.** TASK-050's merge advice ("take the deletion") is safe to act on.
+- **The change was mandatory.** `bin/perry-state:2225` builds `decisions.count`
+  and `decisions.last` from `snap.adrs`. On the branch,
+  `perry-state --json` reports `count: 10, last: ADR-010`. Mutation 8 (the
+  reader returning nothing) is red in `test_parsers` and
+  `test_project_root_resolution` — the silent-zero regression is guarded.
+- `bin/perry-migrate:1189`'s `P.parse_decisions(text)` call was correctly removed
+  with the signature change; no stale caller of the old signature survives.
+
+### Claim 8 — the defect the full run caught, and the guard still fires ✅
+
+`b57a34a` is one line in `SKILL.md`, no test touched. I reverted the wording on a
+copy and the guard fires:
+
+```
+FAIL: test_no_procedure_hand_edits_a_tool_owned_file
+AssertionError: ['  SKILL.md:75  [R1] OKR.md § Commitments …']  != []
+```
+
+The fix is a real wording change, not a loosened test, and `SKILL.md` is 20,439
+bytes — 41 under the 20,480 cap.
+
+---
+
+## 4 · Green-for-the-wrong-reason sweep, and what rode along
+
+**Every added test has a mutation that reddens it**, with one exception:
+`TestListContract.test_a_project_that_never_bootstrapped_lists_cleanly_too`
+asserts `([], 0, 0)` and would stay green under a reader that always returns
+empty. It is weak on its own; mutation 8 covers that failure mode elsewhere, and
+`test_the_shape_is_exact_and_every_key_always_present` carries
+`assertTrue(d["decisions"])` against vacuity. Acceptable.
+
+**No vacuous fixture.** The rewritten `test_shipped_vocabulary` guard carries
+`assertGreaterEqual(len(templates), 2, "…this glob is now vacuous")`. The
+rewritten `test_ownership` template test carries `assertTrue(entries, "no
+decide-owned files[] entry at all")`. Both are the exact anti-mode this project
+keeps catching, written in by the author.
+
+**`GATE_OFF` is used to opt the decide fixture *out* of ADR-004, i.e. to reach
+the code under test, not to hide a refusal.** Now that `perry-decide` takes no
+gate at all, that line is inert in `test_decide_writer` — harmless, worth a
+sentence to whoever tidies it.
+
+**Rewritten tests were strengthened, not loosened.** `test_conformance §
+TestAbsentIsNotNonConformant` gained an end-to-end `perry-task` refusal it did
+not have; `test_i18n` now asserts a Chinese ADR title round-trips *and* en/zh
+parity where it previously only counted rows; `test_ownership.test_decisions_specifically…`
+went from a hardcoded `for path in (...)` loop to an exact-set assertion plus two
+explicit "the index came back" guards. `test_goals_writer`'s `FOREIGN` list kept
+its size by swapping `DECISIONS.md` for `design/DESIGN-001-x.md`.
+
+**Contract fixtures were spliced, not regenerated.** `contract-key-parity.json`
+is a **4-line diff**, all inside the `perry-decide/list` entry; `perry-task/list/1.18`
+is untouched, so § 7 E's finding really was left for someone else's row.
+`contract-shapes.json` removes the three keys and adds `semantics` + an
+`empty_lists` block; no recorded type moved and no nested key was dropped. The
+fixture's `empty_lists` is recorded metadata — `test_no_key_disappeared` reads
+`empty_lists` from the **live** payload, not the fixture, so adding it loosens
+nothing. One nit: the splice left `contract-shapes.json` with **no trailing
+newline**.
+
+**Ride-alongs across the 61 files: none that go beyond the deletion.**
+`README`/`README_cn` drop one tree line each. `perry-goals`, `perry-knowledge`,
+`perry-diagnose`, `packs/software-ops/architecture.md`, the two `work/state/`
+templates: each is a one-name substitution or an added comment explaining why a
+`DECISIONS.md` reference *stays*. `perry-migrate` loses a dead extractor. No doc
+reworded beyond its subject, no test loosened, no template altered further.
+
+**`.perry/conformance.md`** lost the `DECISIONS.md` declaration row. I checked
+whether that was forced: with the row restored on a copy, `perry-conform status`
+does not show it and `test_conformance` + `test_claims` stay green. So the edit
+was **optional hygiene**, not required — defensible (a signed declaration for a
+deleted file is stale), but it is a coding agent editing a user-declaration
+artifact without being forced to. Flagging, not objecting.
+
+**Fixture rebuilds (§ 7 A) are faithful.** `sample-project`'s ADR bodies carried
+only `> Status: active` before; they now carry `Type`, `Date` and `Sunset`
+transcribed from the index rows — including zh's `Sunset: 2026-09-01 前重议` and
+en's `Sunset: revisit by 2026-08-01`. `witness-project`'s ADR already held every
+field, so only its index was deleted. Nothing was lost in the rebuild, and § 7 A's
+warning that a real project in that state has no migration step is a genuine,
+correctly-scoped finding for another row.
+
+---
+
+## 5 · The one required correction
+
+**`bin/perry-decide`'s justification for removing the ADR-004 gate ends with a
+statement that is false, and it understates the size of a real safety loss.**
+
+The comment (lines ~142–163) is right that the gate had to go — `DECISIONS.md`
+was the only file this tool wrote with a `files[]` shape, `decisions/ADR-*.md` has
+none, `verdict` returns `absent` for it and `absent` passes, so a gate on it could
+not fire. Removing it rather than faking it is correct. Its final sentence is not:
+
+> Until then `perry-decide` writes ADR bodies into an undeclared project, **which
+> is what it already did for the bodies themselves; only the index write was ever
+> gated.**
+
+Measured on `git archive` copies of `main` and of `HEAD`, `PERRY_CONFORMANCE=enforce`,
+nothing declared:
+
+```
+--- MAIN : bootstrap
+perry-decide: wrote ['decisions/', 'DECISIONS.md']
+--- MAIN : new (enforce, nothing declared)
+rc=1
+perry-decide: refused — DECISIONS.md already matches Perry's shape at version 2,
+but no one has declared it. …
+--- files written:  ./.perry/config.md  ./DECISIONS.md        ← NO ADR body
+
+--- BRANCH : bootstrap
+perry-decide: wrote ['decisions/']
+--- BRANCH : new (enforce, nothing declared)
+rc=0
+perry-decide: wrote ADR-001
+--- files written:  ./.perry/config.md  ./decisions/ADR-001-t.md   ← body written
+```
+
+On `main` the gate refused the **whole `new` command**, so no ADR body reached an
+undeclared project either. There is no reachable `main` state where it did: before
+`bootstrap` the file is `absent` and `new` refuses for a missing `decisions/`;
+after `bootstrap` the file exists and undeclared and `new` refuses on the gate.
+The clause "which is what it already did for the bodies themselves" is false in
+every state.
+
+**Why it matters more than a wording nit.** The comment's first paragraph is
+honest — "this lane no longer takes a conformance gate, and that is a loss rather
+than a simplification" — and § 7 B repeats it. But the closing clause is what a
+future reader will use to size the follow-up row, and it tells them the change was
+a non-event. It was not: `perry-decide new` went from **fully refusing** on an
+undeclared project to **writing**. That is the whole of ADR-004's coverage for the
+decide lane, and it is a consequence DESIGN-013 does not accept anywhere — § 4.1
+accepts only the link surface.
+
+**Fix:** delete or correct that clause so it says what was measured — that on
+`main` the index's shape gated the entire command, ADR bodies included, and that
+this branch leaves `perry-decide` writing into undeclared projects. Then file the
+restoration row (giving `decisions/ADR-*.md` a `files[]` shape) with that
+blast radius attached rather than the understated one.
+
+This is a documentation correction on an otherwise thoroughly-verified row, which
+is why it is a PASS condition and not a FAIL. Nothing depends on the clause
+except the priority of the follow-up.
+
+---
+
+## 6 · checked / not-checked
+
+**checked** — full `bash tests/run` on the branch tip (2892/3, quiet machine);
+`perry-lint` (0 errors); `perry-decide list` and `--json` against the real
+`perry/` state root; `perry-state --json` decisions payload; all nine mutations
+on a copy, with `md5`-verified restores; mutation 4 against the complete suite;
+two independent attempts to defeat `TestNothingWritesAnIndex`; the `b57a34a`
+guard re-fired on the pre-fix wording; TASK-214's non-determinism reproduced on
+`main`; the ADR-004 gate loss measured on both trees; the transient
+`indexed_without_file` detector measured on `main`; every added/removed test diff
+read; all 61 files' diffs read; fixture rebuilds compared field-by-field against
+the deleted index rows; both contract fixtures diffed line-by-line; the whole
+tree searched for a replacement index by name, by content and by writer.
+
+**not checked** —
+- **"Red ALONE across the whole suite" for mutations 3 and 9.** Verified alone
+  within their own modules only. Not run suite-wide: the failure direction is
+  harmless (more failures would strengthen, not weaken, the claim) and a full run
+  costs ~8 min each.
+- **`unittest discover` on either tree.** The spec's claim of 3 extra failures
+  from a `test_risks_store` double-import artefact is still unconfirmed, by the
+  author and by me.
+- **§ 7 E's `perry-task/list/1.18` fixture drift** (126 vs 115 `emitted`). I
+  confirmed the fixture was *not* touched, and `test_contract_key_parity` is green
+  either way, so I did not independently re-derive the live numbers.
+- **A full `bash tests/run` on `main`.** Another agent's run was in flight in
+  `scratchpad/rv8-main-6c0d041` and re-running it would have contended for the
+  machine that produced my branch number. My baseline comparison is the author's
+  measured `ee0b36a` figure (2882/3), which my 2892/3 with an identical failure
+  set corroborates.
+- **The `viewer/parsers.py` merge against `coding/task-050-header-index`.** I
+  verified the property that advice rests on (zero header sites added, both old
+  sites inside the replaced block); I did not attempt the merge.

+
+## Why this row exists
+
+Measured by the TASK-235 V4 reviewer 2026-08-30 on both trees, PERRY_CONFORMANCE=enforce with nothing declared: on main, perry-decide new returns rc=1, refuses, and writes NO ADR body; on coding/task-235-decisions-index it returns rc=0 and writes ADR-001. The gate refused the WHOLE command on main, bodies included, and there is no reachable main state where it did not. Removing it was correct — after TASK-235 nothing in the lane has a files[] shape, so a gate on it could not fire — but the effect is that the decide lane went from fully gated to fully ungated, and perry-decide's own justifying comment closes with 'only the index write was ever gated', which is false. The comment is being corrected on the branch; this row is the capability that correction reveals is missing. Raised because the reviewer flagged that the follow-up existed 'nowhere but prose'.

The first question is not how to gate it but WHETHER ADR-004 was ever meant to cover a lane whose artefacts are prose documents — ADR-007 rule 3 says the Python layer never parses a document at all, and a conformance gate is a shape check on a document.

+## Verdict
+
+**PASS.** The ending the author chose — ADR-004's posture explicitly exempts
+the decide lane, written down in three places and pinned by seven tests — is
+the right ending, and the argument that gets there is load-bearing where it
+needs to be. All three findings reproduce. All five open items reproduce. The
+baseline dispute resolves in the author's favour, from a pristine `git archive`
+of the commit.
+
+The one substantive criticism is that **Finding 1's ADR-007 argument is
+contradicted by `bin/perry-decide` itself**, which parses the same documents on
+every command. That does not change the verdict, because Finding 2 — the one
+the author calls load-bearing, and the one I checked first — stands on its own.
+It is recorded below as a correction the reference page should take, and as a
+row.
+
+---
+
+## 1 · The decision this review exists to adjudicate
+
+### Finding 2 first, because it is load-bearing. It holds.
+
+Reproduced on a throwaway project holding `ADR-001` and `ADR-002`, with the
+author's `HYPOTHETICAL_ADR_SPEC` (header fields only) grafted onto a copy of the
+schema **in memory**:
+
+```
+$ PERRY_CONFORMANCE=enforce python3 scratchpad/rv239-probe.py \
+      scratchpad/review-239 scratchpad/rv239/undeclared \
+      decisions/ADR-003-three.md decisions/ADR-001-t1.md
+
+key=decisions/ADR-003-three.md          ← the path `new` is about to mint
+  exists=False verdict.state=absent errors=[] gate.ok=True mode=enforce
+  message:
+
+key=decisions/ADR-001-t1.md             ← written by `new` seconds earlier
+  exists=True  verdict.state=undeclared errors=[] gate.ok=False mode=enforce
+  message: decisions/ADR-001-t1.md already matches Perry's shape at version 2,
+           but no one has declared it. … Declare it with:
+               perry-conform declare decisions/ADR-001-t1.md
+```
+
+**A gate written the way ADR-004 § 5 words it — *a writer gates on the file it
+is about to write* — restores nothing on `perry-decide new`.** The verdict is
+`absent`, `absent` passes, the write proceeds. That is measured, not argued, and
+it is the same reason TASK-235 gave for deleting the previous gate.
+
+I verified the two exits the author says are closed by decision rather than
+difficulty, and they are closed:
+
+- **An index.** `find . -name 'DECISIONS*'` returns only
+  `templates/software/DECISIONS.md` and `templates/ops/DECISIONS.md`, neither
+  touched by the branch (the diff is six files). `bin/perry-decide` still has
+  exactly two write sites, `:417` and `:441`. `TestNothingWritesAnIndex` is
+  filename-agnostic — it enumerates every file under the project root and
+  requires each to match `^decisions/ADR-\d+-[^/]+\.md$`, so `ADRS.md`,
+  `INDEX.md` and `decisions/README.md` all fail it. **I tried to defeat it and
+  could not**, except by the two routes already known: naming the index
+  `decisions/ADR-000-index.md` (matches the regex, dies in `mint_id` and
+  `perry-decide list`), or appending it to `.perry/config.md`, the one path the
+  guard excludes. Neither is a route a real implementation takes.
+- **Gating on a file the command does not touch.** `bin/perry-goals § main`
+  says exactly what the author quotes, verbatim, at `:3240`.
+
+### Finding 3 holds
+
+The same probe: `decisions/ADR-001-t1.md`, written by `perry-decide new` one
+call earlier, comes back `undeclared` with **zero shape errors** and the gate
+refuses, naming `perry-conform declare` — a command `SKILL.md:197` forbids an
+agent from running for the user ("*enforces — never run `perry-conform declare`
+for the user; adoption proposes, the user declares*", confirmed at that line).
+One declare per decision, forever, is a real cost and it is correctly weighed.
+
+### Finding 1 does not hold as written — and it is the weakest leg
+
+The claim is that a conformance verdict on `decisions/ADR-*.md` is *"the parse
+`ADR-007` rule 3 forbids"*. ADR-007's rule 3 reads **"The Python layer never
+parses a document at all."** But `viewer/parsers.py § read_adr_records` —
+reached by `perry-decide list`, `status`, `supersede` and `mint_id` on every
+call — opens each `decisions/ADR-*.md`, runs `adr_header_fields` over it, and
+regexes the `# ` title line:
+
+```
+viewer/parsers.py:2907   for p in sorted(d.glob("ADR-*.md")):
+viewer/parsers.py:2908       text = p.read_text(errors="replace")
+viewer/parsers.py:2909       h = adr_header_fields(text)
+viewer/parsers.py:2915       title = re.sub(r"^ADR-\d+\s*[—:–-]?\s*", "", first[2:].strip()).strip()
+```
+
+and `bin/perry-decide § _flip` (`:425`) *rewrites* that document by regex.
+So the lane's own Python layer already parses and mutates these documents.
+`HYPOTHETICAL_ADR_SPEC` is header-fields-only — precisely the typed header
+`adr_header_fields` already reads, which ADR-007 rule **1** puts under Python's
+ownership, not rule 3. **Finding 1 as phrased proves too much: taken literally
+it condemns `perry-decide list`.**
+
+There is a narrower version that survives — *reading tolerantly is not
+validating, and a verdict turns a foreign document into a refusal* — and the
+reference page should say that instead. Filed as a row below, not as a blocker:
+the author's own framing is that Finding 2 ends the argument, and Finding 2 does.
+
+### Is there a third ending?
+
+**Not one that changes this verdict.** I looked for four:
+
+| Candidate | Why it is not the ending |
+|---|---|
+| Gate `new` on `decisions/` the directory | A directory has no `files[]` shape and `check_file` has nothing to run. Dead. |
+| Make `absent` refuse on a write path | Changes ADR-004 globally, breaks `perry-goals link` (its register may not exist yet) and every first write. A different, larger decision. |
+| Gate only `status`/`supersede`, which do touch an existing file | **Reachable** — the file exists, the verdict fires. Rejected on measurement (Finding 3) plus "a lane half-gated is one nobody can describe", and the rejection is pinned by a test (M9 below). A judgement call, honestly made and explicitly recorded. |
+| A `claims[]` ownership check instead of a conformance gate | **This is the real third guard, and the author found it** — it is open items 2 and 3, measured, named as DESIGN-002 territory, written into the reference page and into `UNGATED_BY_DESIGN["decide"]["not_covered"]`. It was not framed as an ending and **no row was filed**. That is the gap. |
+
+**The author did not route around the closed doors.** No index anywhere in the
+diff, no gate on an untouched file, `bin/perry-decide` calls `gate` nowhere, and
+`.perry/conformance.md` is not in the diff. The escalation is real.
+
+**Ruling on the exemption: correct, and better founded than the result claims.**
+ADR-004's own sentence is *"A project must carry a declared, checkable
+conformance marker: **this project's state files** match Perry's shape… Every
+writer gates on it."* The scope word is in ADR-004 itself. `DESIGN-013 § 1.2`
+line 80 says *"Everything under `evidence/`, `journal/`, `design/`,
+`decisions/`, `handoff/`, `weekly/` and `knowledge/` is a document."* So the
+exemption is not an amendment to ADR-004; it is ADR-004 read as written. The
+author put exactly this into `UNGATED_BY_DESIGN`'s docstring and then argued the
+weaker ADR-007 case louder in the result. The strong form is the one to keep.
+
+---
+
+## 2 · Claims verified with my own measurement
+
+### 2.1 Behaviour, and the control (claim 1) — reproduces exactly
+
+Two hand-built throwaways, identical but for `.perry/conformance.md`
+(hand-written, three rows at shape version 2 — `perry-conform declare` was not
+run). All under `PERRY_CONFORMANCE=enforce`:
+
+| Command | undeclared | declared |
+|---|---|---|
+| `perry-conform check BOARD.md` | rc=1 `undeclared` | rc=0 `conformant` |
+| **`perry-task add …` (control)** | **rc=1 refused, nothing written** | **rc=0 wrote TASK-001** |
+| `perry-decide bootstrap` | rc=0 | rc=0 |
+| `perry-decide new t1 …` | rc=0 wrote ADR-001 | rc=0 wrote ADR-001 |
+| `perry-decide new t2 …` | rc=0 wrote ADR-002 | rc=0 wrote ADR-002 |
+| `perry-decide status ADR-001 --status archived` | rc=0 | rc=0 |
+| `perry-decide supersede ADR-001 ADR-002` | rc=0 | rc=0 |
+| `perry-decide list` | rc=0 | rc=0 |
+| files left behind | `ADR-001-t1.md ADR-002-t2.md` | identical |
+
+The control does its job: same project, same environment, one lane refuses and
+the other does not. Also checked under `advisory` — `bootstrap` and `new` both
+rc=0, so the reference page's *"in `enforce` and in `advisory` alike"* is true.
+
+### 2.2 No index was re-added (claim 2) — confirmed, and I could not defeat the guard
+
+See § 1 above. `git diff --stat 49d83fc..506ab72` is six files:
+`bin/perry-conform` (+67), `bin/perry-decide` (+27, **comment only**),
+`decide/reference/decisions.md` (+86), the evidence doc,
+`tests/test_conformance.py` (+193), `tests/test_procedures_call_the_tool.py`
+(+10/−1). Nothing that could hold an index.
+
+### 2.3 Mutations (claim 3) — I ran ten, on a copy, and every guard reddens
+
+Harness: `scratchpad/rv239-mut.py`, operating on `scratchpad/rv239-copy` only.
+It asserts `tests.test_conformance` green before any edit, requires the anchor
+to occur exactly once, resolves the line number at run time, clears every
+`__pycache__` before each run, sleeps past a whole-second boundary either side,
+and **verifies the restore by md5, aborting on mismatch**. All ten restored
+clean; the copy's `bin/perry-conform`, `bin/perry-decide`,
+`decide/reference/decisions.md` and `tests/test_conformance.py` md5-match the
+reviewed worktree afterwards.
+
+| # | Mutation | File:line | Named red |
+|---|---|---|---|

+
+**M1 is the one that mattered and it reddens with the author's message.** M9 is
+mine and it closes a hole the author's set left: without it,
+`test_every_decide_write_command_is_ungated_not_just_new` was only ever
+reddened by M1, i.e. by `new`, and one could not tell whether it independently
+pins `status`/`supersede`. It does.
+
+**M3c is not a defect.** The two doc tests use `assertIn(f"## {section}", …)`,
+so a heading with an appended suffix keeps them green. That matches this
+project's own pointer resolver: `tests/test_pointers_resolve.py § anchors` /
+`test_no_pointer_names_a_section_that_is_not_there` resolves `key in anchor`
+with an explicit comment saying only that direction is allowed. A suffixed
+heading still resolves the pointer, so the guard is exactly as strong as the
+convention it enforces. Reported because it was worth ruling out.
+
+**Every guard in the new class survives its own deletion.** All seven tests are
+reddened by at least one mutation above; none is reachable only through
+another's failure.
+
+### 2.4 M6's false green (claim 4) — reported, not hidden. Confirmed.
+
+`perry/evidence/2026-08/TASK-239-result.md § 4`: *"M6's first form was a false
+green and is reported rather than hidden. It replaced the fragment after the one
+carrying DESIGN-002, the value still contained the string, and the test stayed
+green — correctly."* The corrected form is the fragment at `:468`, and my own
+M6 against that fragment reddens `…test_the_machine_readable_pointer_resolves_to
+_a_real_section`. The disclosure is accurate. Same paragraph also discloses a
+defect in the author's own harness (`named_failures` misses `test_diagnose`'s
+bare-traceback failure, so absolute counts in `mutate-full.txt` are short by
+one and only deltas are sound) — also volunteered rather than quietly corrected.
+
+### 2.5 Where the rule lives (claim 5) — all three present and reachable
+
+1. **`decide/reference/decisions.md § Why this lane takes no conformance
+   gate`** — 86 lines, inserted as the second section on the page, immediately
+   after the TASK-235 index-deletion section. Names ADR-004, ADR-007,
+   DESIGN-013, DESIGN-002; carries the `### What the exemption does NOT cover`
+   half with both open exposures spelled out.
+2. **`bin/perry-conform § UNGATED_BY_DESIGN`**, rendered live:
+
+```
+   3/3 declared and matching. Declare one with `perry-conform declare <file> --root …`.
+
+   ○ decide (decisions/ADR-*.md) — ungated by decision: its only artefacts are
+     prose documents, and a conformance verdict is a shape check on a document
+     (ADR-007 rule 3, DESIGN-013 § 5.1). A gate on the file `perry-decide new`
+     is about could not fire either — that path does not exist yet, and
+     `absent` passes. See `decide/reference/decisions.md § Why this lane takes
+     no conformance gate`.
+```
+
+   `--json` carries the whole entry under `ungated_by_design`, `not_covered`
+   included.
+3. **`bin/perry-decide`'s gate note** above `ADR_RE` — extended, not rewritten,
+   and it is the only change to that file.
+
+**The exemption is findable from the lane's own page. It is a decision, not a
+silence.** Two nits, neither blocking: the human surface prints `why` and
+`reference` but **not** `not_covered`, so the "does NOT cover" half exists on
+the reference page and in `--json` but not on the surface a user actually
+reads; and the printed line is one unwrapped paragraph.

+
+The four, by name, identical to the author's list:
+

+FAIL: tests.test_heading_title.PerrysOwnHeadingTitles.test_none_of_them_contains_its_own_id
+```
+
+**Ruling on the dispute: the author is right, the number IS a property of the
+commit, and I can name the mechanism that produces a 3.**
+
+**The fourth failure is invisible to a `FAIL:`/`ERROR:` grep.** `tests/run`
+prints `test_diagnose.…test_the_queue_register_reconciles_with_the_queue_on_this
+_repository` as a **bare traceback with no prefix**, while the other three carry
+`FAIL:`. From my own branch-tip run:
+
+```
+✗ test_diagnose.py
+Traceback (most recent call last):
+  File ".../tests/test_diagnose.py", line 1161, in test_the_queue_register_reconciles_with_the_queue_on_this_repository
+AssertionError: 3 != 1 : diagnose and perry-task disagree about how many queue rows are waiting on the user
+
+FAIL: test_perry_itself_passes_its_own_id_checks (test_diagnose.TestUserLoadFindings…)
+FAIL: test_none_of_them_contains_its_own_id (test_heading_title.PerrysOwnHeadingTitles…)
+FAIL: test_no_current_in_the_payload_claims_to_be_a_measurement (test_kr_progress_provenance…)
+```
+
+Count the prefixed lines and you get **3**. Count the failures and you get
+**4** — and `tests/run`'s own summary says `3 module(s) red`, which a reader can
+also mistake for a failure count. **That is almost certainly where TASK-249's
+agent's 3 came from, and it has nothing to do with the working tree.**
+
+The irony is worth recording: **this is the exact defect the author disclosed
+about their own harness** in `TASK-239-result.md § 4` — *"`rj239-mutate.py §
+named_failures` collects lines prefixed `FAIL:` / `ERROR:`, and `tests/run`
+prints one of the pre-existing failures … as a bare traceback with no such
+prefix. So every 'named failures' list in the harness output is short by that
+one."* They found the trap, said so out loud, corrected for it by using deltas
+instead of absolute counts — and it is the same trap that produced the number
+they were being second-guessed on. I walked into it myself on my first grep.
+
+Independent of that mechanism, the tree evidence points the same way: `49d83fc` extracted with `git archive` — no working tree, no
+uncommitted anything — gives **4**. Overlaying `main`'s uncommitted board edits
+gives **4**. So the "uncommitted board edits inflated it" hypothesis is
+falsified in both directions: I could not produce 3 from that commit's tree by
+any board state I had access to. `49d83fc`'s own commit message independently
+records 103 / 3098 / 4 on a quiet machine and explains the fourth
+(`test_heading_title` on a 2026-08-18 evidence document headed *"V4 review —
+TASK-050 / 053 / 057 / 060"*, surfaced when TASK-050 closed and changed which
+evidence the walk attributes). That fourth is a *committed file* fact, not a
+board-state fact — which is why it does not move.
+
+TASK-249's agent's 3 is therefore not explained by the working tree. Most
+likely it counted the three standing failures and set the fourth aside as the
+already-filed finding — but that is inference, and I say so rather than assert
+it.
+
+**The branch tip reproduces the author's figure exactly.** My own
+`bash tests/run` on the copy at `506ab72`: **103 modules · 3105 tests · 529.9s ·
+8 workers · 3 modules red**, and the four failures are the same four, with the
+same assertion messages:
+
+```
+AssertionError: 3 != 1 : diagnose and perry-task disagree about how many queue rows are waiting on the user
+AssertionError: Lists differ: ['ACTION-7', 'D009-1', 'D010-2', 'PROJ-003', 'SPEC-007'] != []
+AssertionError: Lists differ: [('TASK-050', 'V4 review — TASK-050 / 053 / 057 / 060')] != []
+AssertionError: [] is not true : the register carries no asserted `current`
+```
+
+The third is `test_heading_title`, naming the same 2026-08-18 document
+`49d83fc`'s commit message names. Wall time 529.9s against the author's 383.5s
+is load, not content: load 20 at launch rising to 48, against their 22–28.
+
+**`bash tests/run` wrote nothing into the tree it ran in.** I md5'd all **728**
+non-`.pyc` files in the copy before the run and after: **zero digests moved.**
+That independently corroborates the author's report, and says TASK-249's
+`intake-sweep` warning does not reproduce on this tree in this state — which is
+what the author said, in those terms.
+
+**The `+7` arithmetic checks out independently.** `tests.test_conformance` runs
+**69** at `49d83fc` and **76** at `506ab72` — exactly +7, exactly the seven
+tests added. `tests.test_procedures_call_the_tool` runs **22** at both (its
+change is a pinned value, not a test). Those are the only two test files the
+branch touches, so `3098 + 7 = 3105` follows.
+
+---
+
+## 3 · Green for the wrong reason — swept, one nit found
+
+Against the named modes:
+
+- **A fixture parsing zero rows** — no. `Project()`'s board has no task rows but
+  no new test counts rows; the conformance verdicts are computed live and I
+  reproduced both of them out-of-band.
+- **A test grepping its own source for a phrase in its own docstring** — no.
+  Tests 5 and 7 read `decide/reference/decisions.md` and
+  `C.UNGATED_BY_DESIGN`, never their own file.
+- **A substring assertion over a whole file reading its own comment as the
+  defect** — no. Test 5 splits the section out first (`split("\n## ", 1)`,
+  which correctly leaves `###` subsections inside) before asserting the five
+  names.
+- **A control that cannot fail** — one, minor.
+  `test_every_decide_write_command_is_ungated_not_just_new` subTests over
+  `status`, `supersede` **and `list`**; `list` is read-only and rc=0
+  unconditionally. The other two subTests are real (M9).
+- **Builds the dangerous state then asserts something safe** — the whole class
+  asserts the *absence* of a guard, which is deliberate and documented (*"A
+  future row that restores a gate should delete this class, not edit it into
+  agreement"*). M1 and M9 show it reddens the moment a gate appears.
+
+**The one nit.** In `test_a_gate_on_the_file_new_writes_could_not_fire`, the
+`HYPOTHETICAL_ADR_SPEC` is inert: `verdict` returns `absent` for *any*
+non-existent path, with or without the entry. Measured:
+
+```
+$ PERRY_CONFORMANCE=enforce python3 scratchpad/rv239-probe2.py …   # PLAIN schema
+PLAIN SCHEMA key=decisions/ADR-003-three.md exists=False state=absent gate.ok=True
+PLAIN SCHEMA key=decisions/ADR-001-t1.md    exists=True  state=absent gate.ok=True
+```
+
+So that test would pass with the hypothetical spec deleted. It is **not** a
+false green — the finding it reports is true, and is in fact *more* robust than
+the test claims — but the test does not by itself prove the spec is in effect.
+It does not need to: `test_the_gate_that_could_fire_would_refuse_perrys_own_
+fresh_output` *does* depend on the spec (with the plain schema the existing ADR
+is `absent`, not `undeclared`), so a glob typo in the shared
+`schema_with_an_adr_shape()` helper reddens there. The pair is sound.
+
+---
+
+## 4 · The five open items — ruling on each
+
+**1 · The ADR ratifying the exemption. Not minting it was right.**
+`SKILL.md:197` and ADR-004 § 4 point 4 (*"The user declares… Mandatory migration
+means the tool may refuse without it; it never means the tool may perform it
+unasked"*) both point the same way, and `perry-decide new`'s own note says this
+tool "writes structure, never reasoning". Minting ADR-011 would have been a
+coding agent signing a decision. **And on my reading it is less needed than the
+author thinks**: ADR-004's sentence is scoped to *state files* in ADR-004's own
+text, and `DESIGN-013 § 1.2` puts `decisions/` outside that set — so the
+exemption is an interpretation, not an amendment. **Still a row** (the user
+should confirm the reading), but a smaller one than "amend ADR-004".
+→ **row, user-signed.**
+
+**2 · `status`/`supersede` rewrite a foreign ADR body. Reproduced exactly, and
+it blocks nothing here.**
+
+```
+before:  > Status: Proposed
+$ PERRY_CONFORMANCE=enforce perry-decide status ADR-001 --status archived --root …/foreign
+perry-decide: wrote ADR-001    rc=0
+after:   > Status: archived
+```
+
+`bin/perry-decide § _flip:425` regex-rewrites the line. The author is right that
+conformance cannot fix it — declaring the file is what conformance *asks for*,
+and after declaring, the rewrite proceeds. **This is the real guard the lane
+needs, and it is the third ending nobody named.** → **row (DESIGN-002 `claims[]`
+ownership check), and it should be filed now rather than left in prose — that is
+precisely the complaint TASK-239 itself was raised on.**
+
+**3 · `new` mints into a `decisions/` Perry did not create. Reproduced exactly.**
+
+```
+$ perry-decide new x --title X --type Process --root …/foreign   → wrote ADR-002  rc=0
+$ ls …/foreign/decisions
+0002-adr-tools-naming.md  ADR-001-someone-elses.md  ADR-002-x.md
+$ perry-decide bootstrap --root …/foreign
+perry-decide: refused — …/decisions already exists …    rc=1
+```
+
+`read_adr_records` globs `ADR-*.md` (`viewer/parsers.py:2907`), so the adr-tools
+file is invisible to `mint_id`. Same lane, same answer as item 2.
+→ **same row as item 2.**
+
+**4 · `perry-knowledge promote` writes a `files[]`-shaped path with no gate.
+Confirmed — and it is worse than the author found.** `grep -n 'conform\|gate'
+bin/perry-knowledge` returns nothing, and `knowledge/*/*.md` is a `files[]`
+entry (twice, as `knowledge` and `knowledge-card`). But the sweep stopped one
+tool short. **`bin/perry-tasks` rewrites `BOARD.md` itself, on an undeclared
+project, under `enforce`, with no gate and no warning:**
+
+```
+$ PERRY_CONFORMANCE=enforce python3 bin/perry-task  add … --root …/undeclared
+perry-task: refused — BOARD.md … no one has declared it …          rc=1
+
+$ md5 -q …/undeclared/BOARD.md
+c99d4f03b873a234cd5a31d74e24cc89
+$ PERRY_CONFORMANCE=enforce python3 bin/perry-tasks render --write --root …/undeclared
+perry-tasks: rendered …/undeclared/BOARD.md from 1 stored record(s)  rc=0
+$ md5 -q …/undeclared/BOARD.md
+75aa29577cb14c3ddd592879891bf4c5
+$ grep -n MUTATED …/undeclared/BOARD.md
+12:| TASK-001 | MUTATED BY REVIEWER | Coding Agent | not_started | — | — |
+```
+
+There are exactly two `gate(` call sites in all of `bin/`: `perry-task:7194` and
+`perry-goals:3251`. `perry-tasks` has its own claim and shape guards but takes
+no conformance gate on the canonical gated file.
+
+**This changes what the exemption means, as the brief anticipated.** It does not
+weaken it — it shows ADR-004's *"Every writer gates on it"* was never literally
+true of the shipped tools, so `decide` is not a novel hole. But it does mean the
+new `UNGATED_BY_DESIGN` surface, whose stated purpose is *"a reader who stops at
+the count line concludes the rest is covered — it is not"*, currently lists one
+lane out of at least three and reads as exhaustive. **The surface replaces one
+false impression with a narrower one.** → **row: sweep every writer against
+ADR-004 and either gate it or register it; and either populate the registry or
+say on the surface that it is not exhaustive.** Not a blocker for this branch —
+both are pre-existing and untouched by it — but it is the finding this row is
+most responsible for having surfaced.
+
+**5 · `perry-decide supersede` prints `wrote None`. Reproduced.**
+
+```
+$ perry-decide supersede ADR-001 ADR-002 --root …/foreign
+perry-decide: wrote None      rc=0
+```
+
+`cmd_supersede` returns `{"superseded":…, "by":…}` and `main`'s human branch
+prints `result.get('id') or result.get('created')`. **Leaving it was right.**
+This branch touches `bin/perry-decide` for a comment only; a one-line behaviour
+ride-along in the file under review is how a small diff stops being reviewable.
+→ **row, one line.**
+
+---
+
+## 5 · checked / not-checked
+
+**checked** — the branch diff, all six files; `perry-decide` × every command ×
+{undeclared, declared} × `enforce`, by exit code and by files left behind, plus
+`advisory` on `bootstrap`/`new`; `perry-task add` as the gated-lane control on
+the same two throwaways; the declared fixture's marker hand-written, never via
+`perry-conform declare`; both hypothetical-schema verdicts reproduced
+out-of-band, and reproduced again **without** the hypothetical entry to test
+whether it was load-bearing; the foreign-ADR rewrite, the foreign-`decisions/`
+mint, the `bootstrap` refusal and `wrote None`, all on a throwaway; `find` and
+write-site checks for a re-added index, plus an attempt to defeat
+`TestNothingWritesAnIndex` by construction; ten mutations on a copy with md5
+restore verification, including four the author did not run; the full suite at
+the branch tip on a copy (**103 / 3105 / the same 4**), with all 728 of that
+copy's files md5'd before and after it to test TASK-249's write warning; the
+fork point extracted with `git archive` and run clean, then re-run with `main`'s uncommitted board state overlaid, to settle the
+baseline dispute; per-module test counts at both ends to verify `+7`;
+`perry-lint` on the branch tip (**0 errors, 4 warnings**, the four pre-existing
+`NS-01` notices); `perry-conform status` in both renders; `SKILL.md:197`,
+`ADR-004 § "The mechanism this requires"`, `ADR-007 § Decision`,
+`DESIGN-013 § 1.2 / § 5.1`, and `perry-goals § main`'s gate comment read at
+source; `git status --porcelain` on the reviewed worktree empty at start and end.
+
+**not checked** —
+- **`unittest discover` on either tree.** Same gap the author and TASK-235's
+  reviewer left open. I ran `bash tests/run` and per-module `unittest`.
+- **A full-suite run at `49d83fc` with the parallel runner.** I ran the four
+  named modules there serially, twice, on two board states. The 3-vs-4 ruling
+  rests on those plus the commit's own recorded figure, not on a fresh 3098-test
+  count of my own.
+- **Whether `perry-tasks`' missing gate is deliberate.** I measured its absence
+  and found no documented exemption; I did not read its history.
+- **Whether the exemption is right for a project other than Perry.** Same gap the

+  project with a large hand-written `decisions/` predating Perry is exactly what
+  open items 2 and 3 describe and I had none to run against.
+- **`/Users/bytedance/proj/Perry` itself.** Never run against, read only. Its
+  `perry/BOARD.md` and `perry/tasks.jsonl` were copied out for the baseline
+  overlay and nothing was written back.

+
+## 1 · Which mechanism, and why it took three passes
+
+The spec offered a choice: refuse a row that cannot round-trip, or strip
+decoration only where a documented rule says it may be. I took the round trip,
+as instructed — **and it does not reach all three shapes.** It closes two of
+them completely; the third needs a second, contextual mechanism, and getting
+that second mechanism right took the round-2 pass this section now records.
+
+### The round trip — `render_row(parsed cells) == line`
+
+`viewer/parsers.py § read_conformance`, after the header skip and the numeric
+version check:
+
+```python
+canonical = render_row([rel, str(int(ver)), declared, route or "declare"])
+...
+if canonical != line:
+    rec.unreadable.append((i, line.strip()))
+    continue
+```
+
+The canonical form is `render_row` — the same writer `bin/perry-conform § render`
+uses to produce the file — so this adds **no second definition** of what a
+declaration looks like. It is **one property, not a list of decorations**, which
+is the whole reason for it: a list closes the shapes that have been found and is
+defeated by the next one. TASK-050 spent nine V4 rounds on this same file
+learning that, and § 2 below is this task learning it a second time.
+
+It closes the **backticked** and **indented** rows, and every other decoration
+written *inside* the row — measured below, it also refuses a five-cell row, a
+`07` version cell, an empty route cell, and a row with trailing whitespace, none
+of which it refused before.
+
+### Fence tracking — and why the round trip cannot do this one
+
+**A fenced row is byte-for-byte identical to a genuine one.** What makes it not
+a declaration is *where it sits*, not how it is written, so no property of the
+row alone can see it: any function of the row returns the same value for both.
+Measured, with the round trip in and fence tracking out (mutation **M2/M3**
+below): the fenced trap parses as a real declaration and the verdict flips, and
+**no other test moves**. The two mechanisms redden disjoint sets.
+
+~~**This corrects a claim in the TASK-226 V4 review**, which called
+`render(parse(row)) == row` *"a complete detector for this class."*~~
+**This corrects a claim in `TASK-241-spec.md § Deliverable`**, which called
+`render(parse(row)) == row` a detector the TASK-226 reviewer had shown complete
+for this class. The reviewer showed no such thing about a per-**row** check: its
+detector was `render(parse(f)) == f` over the **whole file**, used forensically
+on two actual files, and as stated it was true and it does catch the fenced row.
+The per-row form was introduced by the spec, and the spec has since carried the
+correction itself. I inherited the sentence and named the wrong author for the
+error — the correction is real, the attribution was not.
+
+### Why the whole-file fixed point is still not the reader's rule
+
+Round 1 argued that a whole-file check would force the reader to know
+`perry-conform`'s `HEADER`, a second definition of the shape. **That argument is
+weak and I withdraw it.** `HEADER` is hoistable into `viewer/tables.py` exactly
+as `render_row` already is, and both the writer and the reader would import it —
+which is precisely my own defence of the round trip, turned against my own
+objection. It is about where a constant sits, not about structure.
+
+The two reasons that do hold:
+
+1. **All-or-nothing.** `render(parse(f)) == f` fails on one stray blank line,
+   one hand-added note, one older header wording — and then *every* declaration
+   in the file is void at once and the enforce gate shuts on the whole project.
+   The per-row property degrades: one bad row, one refusal, the rest still
+   declare. On a file whose own header says *"Delete a row to withdraw a
+   declaration"*, that difference is decisive.
+2. **Version coupling.** `HEADER` is prose citing ADR-004 § 4 and has been
+   reworded before. A whole-file fixed point makes every record in the wild
+   unreadable the day it is reworded again.
+
+Both refusals report through `ConformanceRecord.unreadable`, which the spec
+correctly identified as where this belongs — it already existed for exactly
+this, `perry-conform status` already prints it (`bin/perry-conform:541,560`),
+and the enforce-gate refusal already appends `(N row(s) … could not be read)`
+(`bin/perry-conform:335`). No new surface was invented.

+
+## 2 · Round 2 · the fence has to be markdown's fence
+
+### What was wrong
+
+```python
+_FENCE = re.compile(r"^\s*(?:`{3,}|~{3,})")
+if _FENCE.match(line):
+    in_fence = not in_fence
+```
+
+A boolean, flipped by **any** fence-looking line. CommonMark § 4.5 closes a
+fenced block only on the **same delimiter character**, at **at least the opening
+run length**, indented at most three, with **nothing after it**. Every line that
+looks like a fence but is *content inside a longer or differently-charactered
+one* flipped the toggle off — and a fence nested inside another fence is how
+every markdown document that shows a fenced block writes it.
+
+### The rule now
+
+```python
+_FENCE = re.compile(r"^(\s*)(`{3,}|~{3,})(.*)$")
+...
+fence: tuple[str, int] | None = None
+for i, line in enumerate(text.split("\n"), start=1):
+    f = _FENCE.match(line)
+    if f:
+        run, rest = f.group(2), f.group(3)
+        if fence is None:
+            fence = (run[0], len(run))
+        elif (run[0] == fence[0] and len(run) >= fence[1]
+              and len(f.group(1).expandtabs(4)) < 4 and not rest.strip()):
+            fence = None
+        continue
+```
+
+`fence` holds the **open fence's `(character, run length)`**, not a bool.
+
+**Opening is liberal, closing is strict, and each direction is chosen
+fail-closed.** Any run of three or more backticks or tildes at any indent
+*opens* — including the two shapes CommonMark says are **not** openers, a
+backtick fence whose info string contains a backtick and a fence indented four
+or more spaces — because an unsure line costs a loud `unreadable` if we treat it
+as a fence and a false `conformant` if we do not, on the file that gates every
+write. Closing follows CommonMark exactly. Strict CommonMark on the *opening*
+side would have reopened two shapes this closes; mutations **M12** and **M13**
+are exactly those two changes, and each reddens its own test.
+
+### Which mechanism I chose, and why — the contiguous-run framing, measured
+
+The reviewer offered a third framing: **require the row to be in the contiguous
+run of rows following the `| File | … |` header.** No `HEADER` prose, no fence
+bookkeeping, immune to the toggle defect. If it worked it is strictly smaller
+than tracking fences and I would have taken it.
+
+I built it (`scratchpad/rd2/fixB-contiguous`, ~8 lines) and probed it against
+the same catalogue. **It closes every bare-row-in-a-fence shape, including all
+four nestings — and then reads an ordinary fenced example *table* as a
+declaration**, because the example carries its own `| File |` header and so
+starts its own contiguous run:
+
+```
+                                     round 1   fence tracking   contiguous run
+  15 whole table inside a fence      undecl.2   undeclared 2     CONFORMANT 0
+  16 whole table in a NESTED fence   confmt.0   undeclared 2     CONFORMANT 0
+  17 blank line inside the table     confmt.0   conformant 0     undeclared 1
+  20 prose line, then a real row     confmt.0   conformant 0     undeclared 1
+```
+
+A document showing what a conformance record looks like writes the header, the
+`|---|` delimiter and the row — not one bare row. So the contiguous run does not
+close shape 3; it **relocates** it to the shape a real document actually has,
+and it is fail-open in the relocation. It also refuses two rows that are
+genuinely declarations today.
+
+It could be tightened to "only the **first** header run counts", which would
+refuse the fenced table — at the cost of voiding the whole real table if any
+example table precedes it. That is **the same all-or-nothing failure § 1 rejects
+the whole-file fixed point for**, reached by document order instead of by a
+stray line. I did not take it.
+
+**Two things the V4 reviewer added to this rejection, both of which I had
+missed.** It built the framing independently from round 1's own sentence, into
+its own copy, without seeing my prototype, and probed it against its own
+catalogue; the measurements above reproduce cell for cell. On top of them:
+
+- **It would have been a REGRESSION, not merely a non-fix.** Catalogue row 15 —
+  the whole table in a *plain, unnested* fence — is already closed by round 1's
+  broken toggle (`undeclared 2`). The contiguous run **hands it back**. I framed
+  the rejection as "closes nothing new here"; it is worse than that.
+- The "first run only" patch is not a different idea from the whole-file fixed
+  point, it is that idea in another coordinate. Stated above.
+
+**Chosen: CommonMark's closing rule inside the same function.** It is the only
+one of the three that leaves every one of the 21 markdown shapes probed below in
+the right state — rows 21-23, the HTML shapes, are outside every one of the
+three and § 9 says so. `test_a_whole_table_inside_a_nested_fence_declares_nothing` is the named
+test for the shape that decided it.
+
+### The catalogue — 26 shapes, three trees
+
+`scratchpad/rd2/probe.py`, my own script: synthetic `mktemp` projects, each
+tree's own `bin/perry-conform`, `PERRY_HOME` / `PERRY_CONFORMANCE` /
+`PERRY_PROJECT` unset, record = that tree's own `HEADER` plus the body. All
+three trees are `git archive` copies.
+
+| # | body planted between `HEADER` and EOF | `658e8c9` (before) | `8c34973` (round 1) | `5054bd6` (round 2) |

+| 21 | a row inside a `<pre>` block | conformant 0 | conformant 0 | **conformant 0** |
+| 22 | a row inside an HTML comment | conformant 0 | conformant 0 | **conformant 0** |
+| 23 | a row inside `<details>` | conformant 0 | conformant 0 | **conformant 0** |
+| 24 | an empty route cell | conformant 0 | undeclared 1 | undeclared 1 |
+| 25 | a leading-zero version cell (`02`) | conformant 0 | undeclared 1 | undeclared 1 |
+
+Bold in the round-1 column = fail-**open**, the FAIL. Bold in the round-2 column
+= rows that must stay declarations and do — **except 21-23, which must NOT and
+still do**: those are the HTML constructs § 9 now states plainly, unchanged
+across all three trees and outside all three candidate mechanisms. 24 and 25 are
+the two shapes § 9 declares changed without a named test, and they are the two
+that M16 and M17 in § 4 revert. Six shapes closed by round 2 —
+04, 05, 06, 09, 12, 16 — of which **09 and 12 the review had not probed** and
+16 is the one that decided the mechanism. Nothing regressed: no cell moves from
+`undeclared` to `conformant` between round 1 and round 2, and the four
+legitimate rows still declare.
+
+### And the laundering, closed with it
+
+`scratchpad/rd2/launder.py`, tilde-wrapping-backtick body, then a legitimate

+Bold = added in round 2. **One test per shape, never one test over several.**
+A single fence test would pass with five of the six nestings regressed — which
+is exactly what happened: round 1 had one, and it was green through the FAIL.
+
+**Every shape test carries the same control.** Before planting the decorated row
+it plants the *undecorated* one and asserts the verdict really does flip to
+`conformant`:
+
+```python
+def assert_trap_would_have_worked(self):
+    self.assertEqual(self.plant(self.canonical()), (C.CONFORMANT, 0), …)
+```
+
+So none can pass because the reader stopped reading, because the fixture stopped
+being lint-clean, or because the row was malformed for some fourth reason. The
+controls are **proved able to fail**: mutation **M15** makes the reader stop
+reading and 29 tests go red, each of the shape tests at line 1265 — the control
+clause inside `assert_trap_would_have_worked`, not the assertion under it:
+
+```
+FAIL: test_a_backtick_fence_nested_in_a_tilde_fence_is_still_a_fence
+  test_conformance.py:1313  self.assert_trap_would_have_worked()
+  test_conformance.py:1265  self.assertEqual(
+  AssertionError: Tuples differ: ('undeclared', 0) != ('conformant', 0)
+  : the control row no longer declares BOARD.md — the three tests below would
+    pass for the wrong reason
+```
+
+**Mutation M7** (an over-strict canonical) reddens the same clause, so the
+control is live under a fix that is too tight as well as one that is too loose.
+
+---
+
+## 4 · Mutations — anchor, old text, named test that reddened
+
+Harness: `scratchpad/rd2/mutate.py`, run against a `git archive` copy of
+`5054bd6`. It anchors **by line number with an assertion on the old text**
+(`assert lines[n].strip() == old.strip()`), clears every `__pycache__` and
+**walks the clock past the next whole second** before each run, and restores the
+target from a pristine copy **verified by `md5`** before every mutation and
+after the last. Pristine `viewer/parsers.py` md5 `2de201a322bca821b0618a5557da7407`
+= `git show 5054bd6:viewer/parsers.py | md5`; the harness's own final line
+reports the same digest. Baseline with no mutation: **OK**.
+
+I checked **every guard I wrote, not only the one the spec names**, and re-ran
+the seven from round 1 against the new code.
+
+| # | old text → new | named test(s) that went RED |

+| **M15** | the reader stops reading (`return rec` at the top of the loop) | 29 — **every control fires** |
+
+**M8–M13 are the point of round 2.** Each of the four clauses of the closing
+rule, and each half of the deliberately-liberal opening rule, has **exactly one
+uniquely-reddening named test** (M9, M10, M11, M12, M13 redden one test each;
+M8's four are the character-check's four distinct shapes). **No clause of the
+FENCE RULE can be deleted or weakened with the suite unchanged.**
+
+That sentence used to read *"no clause of the new mechanism"*, and it was
+broader than what the mutations prove. The V4 reviewer showed it by finding two
+that are not covered, and I reproduced both on my own harness:
+
+| # | old text → new | red |
+|---|---|---|
+| M16 | `route or "declare"])` → `route])` | **NONE** — `Ran 81 tests … OK` |
+| M17 | `render_row([rel, str(int(ver)), …` → `render_row([rel, ver, …` | **NONE** — `Ran 81 tests … OK` |
+
+Neither is a defect, and I checked that rather than assuming it. Each weakening
+reverts **exactly one** shape to fork-point behaviour, and each of those two
+shapes is one this RESULT's § 9 already declares changed-without-a-named-test:
+M16 makes the **empty route cell** declare again (catalogue row 24: `undeclared 1`
+→ `conformant 0`, and `conformant 0` at the fork point), M17 makes the
+**leading-zero version cell** declare again (row 25, the same three figures), and
+neither touches the other's shape. So the two clauses are real and deliberate
+and simply have no named test — which is what § 9 says about them, and which the
+old sentence contradicted by summarising what I had done instead of stating what
+I had measured. **This is the same failure as § 1's attribution and § 4's sweep
+claim: a completeness claim written from intent rather than from a measurement.
+Third time in this task, and the first two were also caught by a reviewer, not
+by me.**
+
+M1's set and M2/M3's sets are **disjoint**: M1 leaves all ten fence tests green,
+M2/M3 leave backticked and indented green. That is the measurement behind § 1 —
+the two mechanisms are genuinely two, and one test over all the shapes would
+have concealed it.
+
+### The claim in this section that was false
+
+Round 1 wrote: ~~**"Nothing I wrote can be deleted with the suite unchanged."**~~
+**That was false when it was written.** The reviewer neutralised
+
+```python
+except UnrenderableCell:
+    canonical = None
+```
+
+and the suite stayed at `Ran 71 tests … OK`. The guard is **reachable and
+load-bearing**: `read_conformance` splits the record on `"\n"` while `render_row`
+refuses through `line_break_at`, which uses `str.splitlines()` — **eleven**
+boundaries, not one. So a path cell holding `U+2028` (or `\v`, `\f`, `\x85`,
+`\x1c`, `U+2029`) sits inside a single line for the reader and makes the
+canonical form unwritable; without the `except`, `perry-conform status` dies
+with an unhandled `tables.UnrenderableCell` traceback on a hand-edited record —
+on the tool the enforce gate calls.
+
+It now has `test_a_path_cell_that_cannot_be_written_back_is_reported_not_crashed`,
+which asserts the **exit code** as well as the report (a crash and a refusal both
+produce no declaration, so asserting only the verdict would have passed either
+way), and **M14** is its mutation. The sentence is struck rather than removed:
+the claim being wrong, and a reviewer finding it by deletion rather than by
+reading, is the part worth keeping.
+
+---
+
+## 5 · The asterisk case did not regress
+
+Three independent checks, all agreeing:
+
+1. **The catalogue** — row 00 and the asterisk probe are byte-identical across
+   all three trees.
+2. **`test_an_asterisked_path_reads_exactly_as_it_did_before`**: the record still
+   parses to the decorated key `**BOARD.md**`, with `unreadable == []`, and
+   `BOARD.md`'s own verdict is still `undeclared`. ``strip("` ")`` never removed
+   asterisks, so `| **BOARD.md** |` is *already* exactly what `render` would
+   write for the key `**BOARD.md**` — the round trip lets it through by
+   construction, not by an exception carved for it.
+3. **The bolded `| **File** |` header** is still squashed to `file` and skipped
+   *before* the guard runs, so it is not reported as an unreadable row —
+   `test_a_bolded_header_row_is_still_not_a_row`, plus
+   `tests/test_one_header_rule.py § TestTheFifthCopy`, both green. **M5** reverts
+   `squash` to the old ``strip("` ").lower()`` and reddens both.
+
+**M6** is the guard against the over-fix: widening the cell strip to
+``strip("`* ")`` — the natural "while we are here, handle bold too" change —
+would make `| **BOARD.md** |` declare the *real* key `BOARD.md`. It reddens
+`test_an_asterisked_path_reads_exactly_as_it_did_before`, so the pin is live.

+## 6 · Baselines — runner and tree
+
+All `git archive` copies, `bash tests/run`, same host, 2026-08-30.
+**Both figures were measured in this round; neither was carried from a brief.**
+
+| tree | runner | modules · tests · time | failures |
+|---|---|---|---|
+| `git archive` copy of **`658e8c9`** — the fork point | `bash tests/run` (8 workers) | 100 · 2992 · 346.0s | **3** in 2 modules |
+| `git archive` copy of **the code commit `5054bd6`** | `bash tests/run` (8 workers) | 100 · 3009 · 165.8s | **3** in 2 modules |
+| `git archive` copy of **branch HEAD `23c8c5d`** | `bash tests/run` (8 workers) | 100 · 3009 · 441.4s | **4** in 3 modules — see below |
+
+`+17 tests` over the fork point is exactly the seven round 1 added plus the
+ten round 2 adds (2992 → 2999 → 3009). The wall-clock figures are not
+comparable to each other — the two runs shared a host with other work — but the
+module and test counts and the failure sets are. Three failures are common to all three runs and all
+three are pre-existing at the fork point:
+
+- `test_diagnose.DecisionsAreCountedPerRecordNotPerMention.test_the_queue_register_reconciles_with_the_queue_on_this_repository`
+- `test_diagnose.TestUserLoadFindings.test_perry_itself_passes_its_own_id_checks`
+- `test_kr_progress_provenance.TestBothOfTodaysWrongReadingsFlip.test_no_current_in_the_payload_claims_to_be_a_measurement`
+
+**Three notes on the numbers, and one is a correction of my own round-1 text.**
+
+- **The baseline is the FORK POINT `658e8c9`, not `main`.** `main` has moved
+  again, twice — it was `9db8f45` when I measured, `84aee3b` when I finished
+  writing this, and it has since been **merged into this branch** at `3c5f186`
+  (see the next note). TASK-233 landed a **parallel test runner**
+  and rewrote `tests/run` itself. A `bash tests/run` figure from today's `main`
+  and one from this branch would not be the same runner, so the only honest
+  before/after is against the tree this branch forked from. Round 1's table
+  named `main @ d2467fc`; that tree's `bash tests/run` produced 100 · 2992 · 3,
+  and so does `658e8c9` here, so the two agree — but the label was loose and
+  this one is not.
+- **The failure count is board-dependent and I did not take it on trust.** The
+  brief for round 1 predicted 5 and the number was 3; the round-1 RESULT said so
+  but did not say why. It is `conformance.in_progress_with_no_live_run` inside
+  `test_diagnose`, which reads the tree's own board — so the figure moves when
+  the board moves. Both runs above are `git archive` copies, which pin the board
+  to a commit, which is why they are comparable at all. **A live-worktree figure
+  is not comparable to either** and I did not measure one this round: minting the
+  six stores a live run needs is a write to the worktree, and the reviewer's
+  ruling that the archive copies carry the comparison stands.
+- **`main` was merged INTO this branch after those two runs, and the merged tree
+  is measured too.** `3c5f186` brought 18 commits — records, and TASK-233's
+  parallel runner, which rewrites `tests/run` and `tests/parallel` and adds
+  `tests/test_parallel_runner.py`. **It touches none of this row's files**:
+  `viewer/parsers.py`, `tests/test_conformance.py`, `tests/test_one_header_rule.py`,
+  `bin/perry-conform` and `viewer/tables.py` are byte-identical across the merge
+  (`git diff --name-only d23a1b9 3c5f186` lists none of them, and
+  `viewer/parsers.py` is still md5 `2de201a…`). So the mechanism and its
+  mutations are unaffected, and the two rows above remain the honest
+  before/after — they are the ones that isolate this change. On the merged tree,
+  with TASK-233's runner:
+
+  | tree | runner | modules · tests · time | failures |
+  |---|---|---|---|
+  | `git archive` copy of **`bcb2715`** — HEAD after the merge | `bash tests/run` (8 workers, TASK-233) | 101 · 3036 · 96.3s | **3** in 2 modules |
+
+  Same three failures, `+27` tests and `+1` module from TASK-233 alone, and **no
+  fourth failure** — one more non-reproduction of the flake below, on the tree
+  that will actually merge.
+- **The branch-HEAD run shows a fourth failure and it is a flake, measured as
+  one.** `23c8c5d` differs from `5054bd6` only in
+  `perry/evidence/2026-08/TASK-241-result.md` — markdown, no code, no test — and
+  it added `test_host_support.TestOpenCodeDispatchLimit.test_concurrent_mixed_registers_do_not_exceed_global_cap`
+  to the failure list. I did not wave it away: I re-ran `tests.test_host_support`
+  standalone **three times on `23c8c5d` and three times on `5054bd6`**, and its
+  own class alone once more, and every one of the seven runs was `OK`. It is a
+  concurrency test with a global cap, it does not read `perry/evidence/`, and no
+  code between the two trees differs. Recorded as an unreproducible flake under
+  load rather than dropped from the table. The other three failures are the same
+  three in all three runs.
+- `python3 -m unittest discover -s tests` on the `git archive` copy of
+  **`5054bd6`**: `Ran 3009 tests in 651.112s`, `FAILED (failures=6,
+  skipped=4)`. Same test count as `bash tests/run` on the same
+  tree and exactly **+3 failures** — the `test_risks_store.TestTheReadersAreOneFunction`
+  double-import artefact (`…_the_bullet_and_placeholder_rules_are_one_object`,
+  `…_the_columns_are_one_list`, `…_the_register_header_predicate_is_one_object`),
+  which `tests/run` does not produce because it imports each module once. I did
+  not run `discover` on the fork point.
+
+---
+
+## 7 · What is outside `read_conformance`
+
+The spec asked me to keep the edit inside the function and to say so if I could
+not. **Three lines are outside it**, all in the same file, none inside another
+parser — unchanged from round 1, which the reviewer ruled justified:
+
+1. `viewer/parsers.py:43` — the shared import line, now
+   `from tables import UnrenderableCell, render_row, split_row, squash`.
+2. `viewer/parsers.py § _FENCE` — the pattern, module level beside
+   `_CONFORMANCE_ROW`, matching the existing shape of the file. Round 2 gave it
+   three capture groups; it did not move.
+3. `tests/test_one_header_rule.py § TestTheFifthCopy.probe` — see § 8.
+
+**`TASK-050` at `b5e7be3` changes that same import line** (`from tables import
+header_index, split_row, squash`) **and one line inside `read_conformance`**
+(`squash(rel)` → `header_index([rel]).column("file", "path")`). Both are textual
+conflicts on merge and both resolve mechanically:
+
+- import → `from tables import UnrenderableCell, header_index, render_row, split_row, squash`
+- header check → keep TASK-050's line; my guard sits below it, untouched.
+
+The two changes are semantically orthogonal — theirs decides *which cell is the
+header*, mine decides *whether a non-header row is canonical*. **Whoever merges
+second should re-run `scratchpad/rd2/mutate.py`; its M5 anchor text
+(`if squash(rel) in ("file", "path") or not rel:`) will need updating to
+TASK-050's line.** Round 2 adds six more anchors (M8–M13) inside
+`read_conformance`, none of which TASK-050 touches.
+
+`TASK-235` replaced `parse_decisions`, which this change never touches.
+
+---
+
+## 8 · The one test fixture I changed, and why it kept its power
+
+`tests/test_one_header_rule.py § TestTheFifthCopy.probe` wrote its data row as
+`` | `BOARD.md` | 2 | 2026-08-18 | migrate | `` — **a backticked path**, which
+this change now refuses. It made
+`test_a_bolded_header_is_not_reported_as_a_broken_row` red, correctly.
+
+The row is now plain. The decoration under test in that class is on the
+**header**, not the path, so the row's own shape was incidental. The test keeps
+all of its power: **M5** reverts `squash` to the old rule and `TestTheFifthCopy`
+goes red — measured, not asserted, and re-measured in round 2 against the new
+code.
+
+---
+
+## 9 · What I did not do, and what I could not verify
+
+- **Silently deleting an unreadable row is still not fixed, and still not
+  filed.** `declare` rewrites the whole file from `record.declarations`, so any
+  row the reader calls unreadable is **dropped by the next declare** — visible
+  in § 2's laundering trace, where the fenced block is simply gone afterwards.
+  Pre-existing, fail-closed, reported by `perry-conform status` *before* the
+  declare, and strictly better than laundering; but the set it bites has grown
+  again this round. The V4 reviewer ruled it acceptable to ship and ruled both
+  my judgements right — do not widen scope, do not file it, the PMO owns the
+  board — **and the PMO has since filed it as TASK-246.** Nothing more from me.
+  Note it composes with trailing-whitespace-unreadable: a stray trailing space
+  on a genuine row now silently deletes that declaration at the next declare.
+- **I did not convert the file to `.perry/conformance.jsonl`.** Out of scope per
+  the spec (`TASK-234`).
+- **Behaviour changed beyond the named shapes, deliberately, with no named test
+  of its own**: a row with **more than four cells**, a **leading-zero version
+  cell** (`07`), an **empty route cell**, and a row with **trailing whitespace**
+  are now `unreadable`. All consequences of the one property, all in the safe
+  direction, all ruled non-blocking. **CRLF is not affected** — `Path.read_text`
+  applies universal newlines.
+- **An unclosed fence still swallows the rest of the file** — every row after it
+  is reported unreadable. Probe row 19; fail-closed and loud; no named test.
+- **HTML IS NOT HANDLED, AND THE SENTENCE BELOW USED TO IMPLY IT WAS.** This
+  bullet previously named "a fence-looking line inside an HTML block" among the
+  constructs the reader does not model — true, fail-closed, and misleading by
+  omission, because it described HTML only in the direction where not modelling
+  it is *safe*. The unsafe direction is live: **a bare canonical row inside
+  `<pre>`, inside an HTML comment, or inside `<details>` still declares, and is
+  still laundered by the next `declare`.** Measured on all three trees, same
+  three figures each time:
+
+  ```
+                                   658e8c9      8c34973      5054bd6
+    row inside a <pre> block       conformant 0  conformant 0  conformant 0
+    row inside an HTML comment     conformant 0  conformant 0  conformant 0
+    row inside <details>           conformant 0  conformant 0  conformant 0
+  ```
+
+  **Not a regression** — identical at the fork point, at round 1 and at round 2 —
+  and outside the spec's three named traps, which is why it is not this row's
+  work. It is invisible to the round-trip property by construction, for exactly
+  the reason the fenced row is: the row is byte-identical to a genuine one and
+  only its container says otherwise. Closing it means tracking HTML blocks as
+  well as fences, which is the reader growing a second markdown parser;
+  `TASK-234` dissolves it instead. **The PMO is filing it as its own row beside
+  `TASK-246`.** I did not fix it, and I am not filing it.
+- **What is still open beyond that, and it is a judgement not an oversight.** The
+  reader matches CommonMark on *closing* and is deliberately looser on *opening*.
+  Two further constructs it does not model, both of which make it refuse rows a
+  strict renderer would show, i.e. both fail-closed: a fence inside a **list
+  item** or **blockquote**, where CommonMark measures indent relative to the
+  container and this reader measures it from column 0; and a `|`-row inside an
+  **indented code block** with no fence at all, which the round trip refuses only
+  because such a row is indented. If a future change makes indentation stop
+  implying refusal, that second one reopens. I did not test either by name.
+- **No live-worktree suite figure this round** — see § 6. The comparison is
+  archive-to-archive.
+- **I did not read the `perry-conform status` human (non-`--json`) rendering** of
+  the new unreadable rows. JSON surface only, both rounds.
+- **`perry/BOARD.md` and `perry/tasks.jsonl` are untouched**, as instructed, and
+  `bin/perry-tasks --dry-run` was never used.
+- **Four things the V4 review measured that I have NOT re-run, and cite instead.**
+  Named here so the record shows which figures are mine and which are its:
+  1. **How `declare` was exercised.** Its brief forbade running `declare`
+     anywhere, so it **computed what `declare` writes** via
+     `render(parse(record))` rather than invoking the command, and said so as a
+     method note instead of claiming the command ran. My § 2 laundering trace
+     *does* invoke `declare`, against synthetic `mktemp` projects; the two routes
+     agree, and its route is the more conservative one.
+  2. **Seven "must still declare after a properly closed fence" shapes** — the
+     direction I never probed, since my catalogue's positive control is a record
+     with no fence in it at all. No false refusals.
+  3. **The human, non-`--json` `perry-conform status` rendering** of the new
+     unreadable rows. § 9 of round 1 and of this file both declare I read only
+     the JSON surface; the review closed it.
+  4. **The all-or-nothing argument, quantified.** § 1 asserts that a whole-file
+     fixed point is voided by one stray blank line. The reviewer measured what
+     that costs on the real record: **one stray blank line voids all 23 of
+     Perry's declarations under a whole-file rule, and 0 under the per-row
+     rule.** That is a measurement of my argument, not a rewording of it, and it
+     is the reviewer's number.
+  It also recorded an **eighth** non-reproduction of § 6's `test_host_support`
+  flake: its suite on the merged tree matched the PMO's figure with no fourth
+  failure.
+- **The probe, the mutation harness and the two prototype trees are session
+  scratch, not committed** — `perry/evidence/` holds markdown only, by this
+  repository's own convention. The table in § 4 carries the anchor, the old
+  text, the replacement and the reddened test for each of the seventeen; § 2
+  carries the catalogue and the discarded prototype's measurements.

+# TASK-241 — V4 review, round 2: **PASS**
+
+> Fresh-context reviewer, 2026-08-30. Under review: `3c5f186`, the read-only
+> worktree at `scratchpad/review-241r2` — round 2's code (`5054bd6`) plus `main`
+> merged in by the PMO after the author's numbers were recorded.
+> **Every probe, plant, mutation and suite run below happened on `git archive`
+> exports and `cp -R` copies under `scratchpad/rv241r2/`**, never on the reviewed
+> tree, never on `/Users/bytedance/proj/Perry`, never on another worktree. No
+> write-side Perry tool was run anywhere. `perry-conform declare` was **not run**
+> — see § 2. `setup` was never run. No identifier was minted.
+> Tree integrity: `viewer/parsers.py` in the reviewed worktree is
+> `2de201a322bca821b0618a5557da7407` = `git show 5054bd6:viewer/parsers.py | md5`,
+> and `git status --porcelain --untracked-files=all` was empty before and after.
+
+**Round 1's FAIL is closed, and closed by the right mechanism.** All six
+fail-open shapes flip, nothing regresses, the four legitimate rows still declare,
+the laundering is gone, and every clause of the new fence rule has its own
+uniquely-reddening named test. I reproduced the catalogue, the laundering, the
+corner sweep, all fifteen mutations plus two of my own, the control clause and
+the exit-code
+half of the U+2028 test, and both corrections — independently, with my own
+scripts and my own mutation lines — and every one matched.
+
+**The contiguous-run rejection stands.** I built the reviewer's framing myself,
+from the review's own words, and probed it: it is fail-open exactly where the
+author says it is. That ruling is § 2, and it is the most valuable thing in the
+round.
+
+**One finding, and it does not block: a bare canonical row inside an HTML block
+or an HTML comment still declares, and is still laundered** — pre-existing at
+the fork point, unchanged by both rounds, outside the spec's three named shapes,
+and *not* covered by § 9's list of unmodelled constructs, which reads as though
+it were. § 5.
+
+---
+
+## 1 · The catalogue — reproduced, on my own probe
+
+`scratchpad/rv241r2/rv2-probe.py`, my own script — the author's `rd2/probe.py`
+is session scratch and is not in the tree, so there was nothing to copy from:
+synthetic `mktemp` projects, each tree's own
+`bin/perry-conform`, `PERRY_HOME` / `PERRY_CONFORMANCE` / `PERRY_PROJECT`
+unset, record = that tree's own `HEADER` plus the body, verdict read off
+`perry-conform check BOARD.md --json` (`state`, `record_unreadable_rows`).
+All trees are `git archive` copies.

+
+**Cell for cell identical to the RESULT's § 2 table.** Six flips — 04, 05, 06,
+09, 12, 16 — nothing moves from `undeclared` to `conformant` between round 1 and
+round 2, and the four legitimate rows (00, 17, 18, 20) still declare. The
+asterisk column is byte-identical across all three trees.
+
+**Claim 3 verified in passing**: 09 and 12 are `conformant 0` on round 1 — both
+fail-open, both unprobed by the round-1 review — and both shut in round 2.
+
+The merged tree I am reviewing behaves identically to the code commit: I ran the
+same 22 shapes against `t-3c5f186` and every cell matches `t-5054bd6`, which is
+expected since `viewer/parsers.py`, `tests/test_conformance.py`,
+`tests/test_one_header_rule.py`, `viewer/tables.py` and `bin/perry-conform` are
+byte-identical between the two.
+
+### The mechanism is not over-strict either — a check nobody ran
+
+A guard that refuses legitimate rows shuts the enforce gate on real projects, so
+I swept the other direction: seven shapes where a fence is **properly closed**
+and a real row follows it (closed by a longer run; closed exactly; closed at a
+3-space indent; tilde; with an info string; a fully-closed nested example; a
+4-space-indented opener closed at column 0). **All seven are `conformant 0` on
+all three trees.** No false refusals. And Perry's own shipped
+`.perry/conformance.md` reads as **23 declarations, 0 unreadable**.
+
+---
+
+## 2 · THE RULING THE ROUND ASKED FOR — the contiguous-run framing is fail-open, and the author measured it right
+
+The round-1 review offered: *require the row to be in the contiguous run of rows
+following the `| File | … |` header and its `|---|` delimiter* — "immune to the
+defect in § 1", "no fence bookkeeping at all". The author says they built it,
+probed it, and rejected it because it **relocates** shape 3 rather than closing
+it, fail-open.
+
+**I did not take that on trust and I did not read their prototype.** I wrote my
+own from the review's sentence, into a `cp -R` copy
+(`scratchpad/rv241r2/t-contig`): keep the round trip, delete the fence
+bookkeeping, and add ~8 lines — `in_run` set true by a header row, held across a
+`|---|` delimiter, cleared by any line that is not a table row, and a row refused
+when `in_run` is false.
+
+```
+shape                                      5054bd6 (shipped) | t-contig (reviewer's framing)
+04 tilde fence wrapping backtick fence     undeclared 1      | undeclared 1
+05 4-backtick fence w/ 3-backtick line     undeclared 1      | undeclared 1
+06 backtick fence wrapping tilde fence     undeclared 1      | undeclared 1
+09 fence line w/ trailing text inside      undeclared 1      | undeclared 1
+12 4-space-indented fence line inside      undeclared 1      | undeclared 1
+15 whole TABLE inside a fence              undeclared 2      | CONFORMANT 0   ← fail-OPEN
+16 whole TABLE inside a nested fence       undeclared 2      | CONFORMANT 0   ← fail-OPEN
+17 blank line inside the real table        conformant 0      | undeclared 1   ← refuses a real row
+20 prose, then a real row                  conformant 0      | undeclared 1   ← refuses a real row
+```
+
+**The author's measurement stands, and the reviewer's framing had a hole neither
+the reviewer nor the PMO saw.** It closes every bare-row-in-a-fence shape
+including all four nestings, and then reads an ordinary fenced example *table* as
+a real declaration, because that example carries its own `| File |` header and so
+starts its own contiguous run. A document that shows what a conformance record
+looks like writes the header, the delimiter and the row — not one bare row — so
+the relocation is *to the shape a real document actually has*. And it refuses two
+rows that legitimately declare today.
+
+Two things I can add to the author's case that the RESULT does not say:
+
+1. **It would have been a regression, not just a non-fix.** Shape 15 — the whole
+   table inside a *plain, unnested* fence — is already `undeclared 2` on round
+   1's broken toggle. The contiguous run hands it back. Taking the reviewer's
+   framing would have re-opened a shape round 1 had closed.
+2. **The escape hatch the RESULT names is worse than it says.** "Only the first
+   header run counts" would void the real table whenever any example table
+   precedes it — which on this file is the same all-or-nothing failure § 1
+   rejects the whole-file fixed point for, but reached by document order rather
+   than by a stray byte.
+
+The author was right to build it and measure it rather than argue about it, and
+right to reject it. `test_a_whole_table_inside_a_nested_fence_declares_nothing`
+is the correct place to pin the decision, and its docstring records the reason.

+
+## 3 · Laundering — measured closed on the nested body
+
+**A note on method, per the standing constraints.** My brief forbids running
+`perry-conform declare` anywhere, so I did **not** invoke it — not even against a
+`mktemp` project, as the round-1 reviewer and the author both did. `declare`
+rewrites the record as `render(<parsed declarations> + <the new one>)`
+(`bin/perry-conform § declare`, `§ render`), so I computed exactly that from the
+parsed record instead: `scratchpad/rv241r2/rv2-launder-one.py` loads each tree's
+own `bin/perry-conform` and `viewer/parsers.py`, plants the body, and prints
+`render()` of what the reader parsed. This isolates the same mechanism; it does
+not exercise `declare`'s file I/O, and I say so in § 8.
+
+```
+### 8c34973 (round 1)                      ### 5054bd6 (round 2)

+```
+
+The whole measured harm of TASK-226/241 — verdict flip plus a plain canonical row
+nothing downstream can tell from a real one — is gone on the nested body. The
+suite's own `test_a_nested_fence_row_is_not_laundered_by_the_next_declare` does
+run the real `declare` inside its own tmpdir fixture, and it is green.

+
+## 4 · Mutations — all fifteen re-run on my own harness, plus two of my own
+
+`scratchpad/rv241r2/rv2-mutate.py`, my own harness against `cp -R` copies of
+`3c5f186`. It anchors **by line number with an assertion on the old text**,
+clears every `__pycache__`, sleeps past the next whole second, and restores from
+a pristine copy **verified by md5** before every mutation and after the last
+(final digest `2de201a322bca821b0618a5557da7407`, unchanged). Modules:
+`tests.test_conformance` + `tests.test_one_header_rule`. Baseline, no mutation:
+`Ran 81 tests … OK` (69 + 12). **I wrote every replacement line myself from the
+description of the clause, not from the author's harness.**
+
+| # | my mutation | red | matches RESULT |
+|---|---|---|---|
+| M1 | `if canonical != line:` → `if False:` | 4: backticked, indented, laundering(backticked), **U+2028** | ✔ |

+| M15 | the reader stops reading (`return rec` at the top of the loop) | 29 | ✔ |
+
+**M9, M10, M11, M12, M13 each redden exactly one test, and exactly the named
+one.** The four clauses of the closing rule and both halves of the liberal
+opening rule are individually pinned. The asymmetry is real in both directions:
+strict CommonMark on *closing* (M8–M11 red) and deliberately liberal on
+*opening* (M12–M13 red) are each held by a test, so neither direction can be
+"tidied" into the other without the suite saying so. That is what makes the
+asymmetry a choice rather than a convenience.
+
+M8's four are the character check's own shapes and only those: the two nestings
+that mix `~~~` with ``` ``` ```, the whole-table nesting, and the nested
+laundering test. The other fence shapes survive M8 because a different clause
+holds them — 05 by the run-length check (same character), 09 by `not
+rest.strip()`, 12 by the indent check — which is why M9, M10 and M11 each redden
+one and only one.
+
+**M1 and M2/M3 are disjoint**, reproduced: M1's four contain no fence test;
+M2/M3's ten contain neither `backticked` nor `indented`. The two mechanisms are
+genuinely two.
+
+**M15 reddens at the control clause.** Targeted re-run, verbatim:
+
+```
+FAIL: test_a_backtick_fence_nested_in_a_tilde_fence_is_still_a_fence
+  tests/test_conformance.py, line 1313, in test_a_backtick_fence_nested_in_a_tilde_fence_is_still_a_fence
+    self.assert_trap_would_have_worked()
+  tests/test_conformance.py, line 1265, in assert_trap_would_have_worked
+    self.assertEqual(
+AssertionError: Tuples differ: ('undeclared', 0) != ('conformant', 0)
+ : the control row no longer declares BOARD.md — the three tests below would
+   pass for the wrong reason
+```
+
+Line 1265, the control clause inside `assert_trap_would_have_worked`, exactly as
+the RESULT quotes it, on both the tests I re-ran individually. **The controls can
+fail.**
+
+### M14 and the exit code — the half that matters
+
+The brief asked me to verify the exit-code half specifically, because a crash and
+a refusal both produce no declaration. Targeted M14 run:
+
+```
+FAIL: test_a_path_cell_that_cannot_be_written_back_is_reported_not_crashed
+  tests/test_conformance.py, line 1428
+    self.assertEqual(rc, 0, f"status crashed on the record: {err}")
+AssertionError: 1 != 0 : status crashed on the record: Traceback (most recent call last):
+  … bin/perry-conform, line 213, in verdict
+    record = P.read_conformance(project_root)
+```
+
+The test reddens **at the exit-code assertion**, with the unhandled
+`UnrenderableCell` propagating out of `perry-conform status`. That is the
+assertion the guard needs and it is the one that fires. § 4's struck sweep claim
+is honestly struck and the replacement test is real.
+
+---
+
+## 5 · THE FINDING — a bare row inside an HTML block or comment still declares
+
+My own corner sweep (`scratchpad/rv241r2/rv2-corners.py`, 15 containers the
+21-shape catalogue does not reach) turned up one fail-open shape:
+
+```
+                                                658e8c9      8c34973     3c5f186
+a bare canonical row inside <pre> … </pre>      conformant 0 conformant 0 conformant 0
+a bare canonical row inside <!-- … -->          conformant 0 conformant 0 conformant 0
+a commented-out row below a real table          conformant 0 conformant 0 conformant 0
+```
+
+And it carries the full harm — `rv2-launder-html.py`, HTML-comment body:
+
+```
+parsed declarations : ['BOARD.md']    unreadable rows : 0
+render(decls) AFTER a declare of .perry/hook.md:
+    | .perry/hook.md | 2 | 2026-08-30 | declare |
+    | BOARD.md | 2 | 2026-08-28 | declare |     ← laundered
+```
+
+Commenting a row out is a plausible way a person tries to withdraw a declaration
+on a file whose own header invites hand editing.
+
+**It does not block, for four reasons, and I want the reasoning on the record
+because it is the one judgement in this review that could have gone the other
+way:**
+
+1. **It is not a regression.** Identical at the fork point, at round 1 and at
+   round 2. This round neither introduced nor widened it.
+2. **It is outside the spec's named work.** The spec names three traps —
+   backticked, indented, fenced — and V4 item 1 asks that each be refused or
+   reported. All three are shut, including every nesting of the third, each with
+   its own named test and a live control.
+3. **The mechanism the spec chose is blind to it by construction.** A row inside
+   an HTML comment is byte-identical to a genuine one, so `render(parse(row)) ==
+   row` cannot see it — the same argument, provable, that the spec, the round-1
+   review and the author all accepted for the fence. Closing HTML containers
+   needs a third contextual mechanism, which is new scope.
+4. **The class is dissolved by TASK-234**, which the spec names and puts out of
+   scope, and which this row was explicitly told not to wait on.
+
+**But § 9 owes a correction.** It reads: *"Three constructs it does not model,
+all of which make it refuse rows a strict renderer would show, i.e. all
+fail-closed: a fence-looking line inside an HTML block; a fence inside a list
+item or blockquote; and a `|`-row inside an indented code block."* Each of those
+three statements is **true as written** — I measured all three, and all three are
+fail-closed (`a ``` line inside <pre>` → `undeclared 1`; a fenced row in a
+blockquote → not matched at all; a row in a 4-space indented block →
+`undeclared 1`). The problem is that the list *mentions HTML blocks* only in the
+fence-line direction, which invites the reading that HTML blocks are handled and
+fail-closed. They are not: the bare-row direction is fail-open with laundering.
+The limits list should name it. **Recommend a row** — it belongs beside TASK-246,
+or folded into TASK-234's scope.
+
+---
+
+## 6 · Green-for-the-wrong-reason sweep — clean
+
+Against the named modes, on all seventeen tests in the class plus the changed
+fixture:
+
+- **Fixture parsing zero rows.** Impossible here: every shape test first plants
+  the *undecorated* row and asserts `(CONFORMANT, 0)`. Proved able to fail by M15
+  and M7 (§ 4), both firing at line 1265.
+- **A control that cannot fail.** Disproved directly — two independent mutations
+  redden the control clause and nothing else in those tests is reached.
+- **A test grepping its own source or docstring.** None. Every test reads
+  `perry-conform status` / `check` output or `read_conformance`'s return value.
+- **A substring assertion over a whole file reading its own comment.** The only
+  ones are in the two laundering tests, against a record the test wrote itself
+  containing no prose beyond `HEADER`; each pairs `assertNotIn` with an
+  `assertIn("| .perry/hook.md |")` that proves the rewrite actually happened, so
+  neither `assertNotIn` is vacuous.
+- **Builds the dangerous state then asserts something safe.** Every shape test
+  asserts the *verdict* **and** `unreadable == 1` (or `2` for the table shapes),
+  so a guard that refused silently would be caught — M4 confirms: neutralising the
+  fenced `unreadable.append` reddens nine of them.
+- The new comment in `tests/test_one_header_rule.py` is a comment only; nothing
+  asserts against it. M5 proves `TestTheFifthCopy` kept its power after the
+  fixture row was de-backticked — measured, not asserted.
+
+**The asterisk case has not regressed.** Three independent confirmations: the
+catalogue row AA is `undeclared 0` byte-identically on all three trees; the
+bolded `| **File** |` header is still squashed to `file` and skipped *before* the
+guard (`test_a_bolded_header_row_is_still_not_a_row` green, and M5 reddens it
+together with both `test_one_header_rule` tests); and M6 — the natural "handle
+bold too" over-fix — reddens exactly one test, the asterisk pin.
+
+### Does any guard survive its own deletion? Two sub-clauses do, and both are declared
+
+I swept the **entire** code delta, not the fifteen. The non-comment diff against
+the fork point is exactly: the import line, `_FENCE`, the ten-line fence block,
+and the seven-line round trip. Everything in it is mutated by M1–M14 except two
+sub-expressions of the canonical form, which I mutated myself:
+
+| my extra | change | suite | behaviour it changes |
+|---|---|---|---|
+| M16 | `route or "declare"` → `route` | `Ran 81 tests … OK` | an **empty route cell** goes `undeclared 1` → `conformant 0` |
+| M17 | `str(int(ver))` → `ver` | `Ran 81 tests … OK` | a **leading-zero version** (`| BOARD.md | 02 | … |`) goes `undeclared 1` → `conformant 0` |
+
+Both weaken the guard back to the fork point's behaviour on those two shapes, and
+neither reopens any named shape. **Both are exactly the shapes § 9 declares**:
+*"a row with more than four cells, a leading-zero version cell (`07`), an empty
+route cell, and a row with trailing whitespace are now `unreadable` … all
+consequences of the one property, all in the safe direction … with no named test
+of its own."* So this is a declared limit measured true, not a concealed one.
+
+**One sentence should still be narrowed.** § 4 says *"No clause of the new
+mechanism can be deleted with the suite unchanged."* In its paragraph that means
+the fence rule, and for the fence rule it is exactly right — M8–M13 prove it.
+Read as covering the round trip too, it is false by M16 and M17. Given that
+round 1's over-broad sweep sentence is struck two paragraphs below, this one
+should say *"no clause of the fence rule"*. **Not a blocker; a wording
+correction.**
+
+---
+
+## 7 · The two corrections — both confirmed
+
+**(a) The attribution.** § 1's sentence is struck in place (`~~…~~`) and replaced
+with *"corrects `TASK-241-spec.md § Deliverable`"*, and the spec carries its own
+appended correction. I checked the source: `TASK-226-v4-review.md:142` and the
+paragraph under it make the claim about **`render(parse(f)) == f` over the whole
+file**, on two actual files — *"That fixed point is a complete detector for the
+whole misparse class."* **True as written**, and it does catch the fenced row.
+The per-row transposition is the spec's. The review's file-level claim was never
+contradicted. Correction accurate, and struck rather than deleted, as the RESULT
+says.
+
+**(b) The "second definition" argument, withdrawn.** The replacement is
+**stronger, not differently worded**, and I measured the difference rather than
+reading it:
+
+```
+Perry's own shipped record: 23 declarations, 0 unreadable
+  render(parse(f)) == f on it                                    : True
+  one stray blank line appended  -> whole-file fixed point: False | per-row: 23 kept, 0 refused
+  one hand-added note line       -> whole-file fixed point: False | per-row: 23 kept, 0 refused
+  one blank line inside the table-> whole-file fixed point: False | per-row: 23 kept, 0 refused
+```
+
+The withdrawn argument was about where a constant sits — refutable, and the
+author concedes it. The replacement is about **failure semantics**: under a
+whole-file reader rule, one stray byte voids all 23 declarations at once and the
+enforce gate shuts on the entire project, while the per-row property loses
+nothing. That is a checkable claim, it checks out, and it is a different and
+better kind of argument than the one it replaces. The version-coupling half is
+sound on its face: `HEADER` is prose citing ADR-004 § 4 and a reworded header
+would void every record in the wild.
+
+---
+
+## 8 · Baselines — and which tree each number came from
+
+`bash tests/run` on a `git archive` copy of **`3c5f186`**, the merged tree I am
+reviewing — the same tree and runner the PMO measured:
+
+```
+101 modules · 3036 tests · 213.6s · 8 workers · 3 failures in 2 modules
+
+  test_diagnose.DecisionsAreCountedPerRecordNotPerMention
+      .test_the_queue_register_reconciles_with_the_queue_on_this_repository
+  test_diagnose.TestUserLoadFindings.test_perry_itself_passes_its_own_id_checks
+  test_kr_progress_provenance.TestBothOfTodaysWrongReadingsFlip
+      .test_no_current_in_the_payload_claims_to_be_a_measurement
+```
+
+**Exactly the PMO's 101 / 3036 / 3, and exactly the three standing failures**,
+all three pre-existing at the fork point and named in the RESULT. My run produced
+**no fourth failure** — see § 9.
+
+`python3 -m unittest tests.test_conformance` on the same copy: **`Ran 69 tests …
+OK`**, matching the PMO's figure.
+
+I also exercised the **human (non-`--json`) `perry-conform status`** rendering of
+the new unreadable rows, which neither round 1 nor the author read:
+
+```
+   · BOARD.md                                     undeclared
+   ✗ .perry/conformance.md:7 unreadable row: | BOARD.md | 2 | 2026-08-28 | declare |
+```
+
+It names the line and the text. And the enforce-gate message carries the count —
+`bin/perry-conform:334`, `f" ({v.record_unreadable} row(s) in .perry/conformance.md
+could not be read and were not counted as declarations)"`. Both surfaces
+pre-existed; no new one was invented, as the RESULT says.
+
+**Every other number in this review is from a `git archive` copy** of the commit
+named beside it: `658e8c9` (fork point), `8c34973` (round 1), `5054bd6` (round 2
+code), `3c5f186` (merged). Mutations ran on `cp -R` copies of `3c5f186`.
+
+**The author's 100 / 3009 / 3 is not a discrepancy** and I did not treat it as
+one. It was measured on `5054bd6` before the PMO merged `main` in; the merge
+brings other tasks' modules and tests with it, which is where the extra module
+and the extra tests come from. The author's choice of the **fork point** rather
+than `main` as the before-baseline is correct and the reason given is the right
+one: TASK-230 rewrote `tests/run` itself, so a `main` figure would not be the
+same runner, and a before/after across two runners measures the runner.
+
+The failure-set caveats hold as stated: two of the three standing failures are
+data-dependent on `conformance.in_progress_with_no_live_run` reading the tree's
+own board, which is why archive copies (board pinned to a commit) are the only
+comparable measurement, and why a live-worktree figure is not comparable to
+either. I measured; I carried nothing.
+
+---
+
+## 9 · The fourth failure on branch HEAD — ruling: **it does not block**
+
+`test_host_support.TestOpenCodeDispatchLimit.test_concurrent_mixed_registers_do_not_exceed_global_cap`
+appeared once on `23c8c5d`, whose only delta from the measured tree is the RESULT
+markdown.
+
+**An unreproducible flake, honestly recorded, does not block, and recording it
+was the right call.** The reasons are all checkable and all check out:
+
+1. **There is no mechanism.** The delta between `5054bd6` and `23c8c5d` is one
+   markdown file under `perry/evidence/`. `git diff --stat` confirms it. The test
+   is a concurrency test with a global cap and does not read `perry/evidence/`.
+2. **It is a known flake on this project**, with a prior measurement: TASK-230
+   fired it 2 of 10 under one schedule and 0 of 5 under another, and declined to
+   claim an effect.
+3. **Seven standalone re-runs were OK**, and the author reports them as such
+   rather than reporting "it passed" and moving on. My own full-suite run on the
+   merged tree — a different tree again, 8 workers, 213.6s — did not produce it
+   either, which is an eighth non-reproduction and still not a disproof.
+4. **The disposition is the correct one.** Leaving it out of the table would have
+   been the fault; recording it, saying it could be bounded but not closed, and
+   not claiming a cause is exactly what an honest baseline looks like.
+
+What would change my ruling: a reproduction, or a delta that could plausibly
+carry one. Neither exists.
+
+---
+
+## 10 · The declared-and-still-open items — none blocks
+
+- **An unclosed fence swallows the rest of the file.** Reproduced (shape 19):
+  `undeclared 1`. Fail-closed, loud through `unreadable`, and the enforce gate
+  refuses rather than proceeding on a false verdict. Acceptable untested by name.
+- **Fences inside HTML blocks, list items and blockquotes.** All three measured
+  fail-closed (§ 5). Acceptable. The *bare-row* direction in HTML containers is
+  the § 5 finding and is a different statement.
+- **TASK-246, the silent deletion of an unreadable row at the next declare.**
+  Reproduced in § 3: the refused row is simply gone from `render()`'s output. It
+  is strictly better than laundering, fail-closed, and reported by
+  `perry-conform status` *before* the declare. The PMO owns the row and has filed
+  it. Not a blocker, and the author was right not to widen scope.
+- **The four shapes newly `unreadable` without named tests** (>4 cells, `07`
+  version, empty route, trailing whitespace). Measured in § 6; all in the safe
+  direction; all declared.
+
+---
+
+## 11 · Not checked
+
+- **`perry-conform declare` as a command.** My brief forbids running it anywhere,
+  so I reproduced the laundering through `render(parse(record))` — the identical
+  computation `declare` performs — instead of invoking it. `declare`'s own file
+  I/O and atomic write are therefore checked only by the suite's two laundering
+  tests, which do run it inside their own tmpdir fixture and are green.
+- **A live-worktree suite figure.** It needs the six stores minted, which is a
+  write. Archive copies only, and I say which commit each came from.
+- **`python3 -m unittest discover`** on any tree. The author's `discover` figure
+  on `5054bd6` (3009 / 6, three extra being the `test_risks_store` double-import
+  artefacts) is reproduced by the round-1 review's identical finding on `8c34973`
+  but not by me on this tree.
+- **CommonMark conformance beyond the 22 catalogue shapes, the 15 corners and the
+  7 must-still-declare shapes I ran.** Lists and blockquotes are modelled only to
+  the extent of confirming they fail closed.

+inert.** Measured on a copy:
+
+1. A decorated row flips a real file from `undeclared` to **`conformant`**.
+2. The next legitimate `perry-conform declare` rewrites the whole file from the
+   parsed declarations — `bin/perry-conform:423 render` — and therefore
+   **launders the decorated row into a plain canonical row**, indistinguishable
+   from one a person wrote on purpose.
+
+Only the **asterisk** case is inert. `TASK-226`'s RESULT files the whole class as
+*"inert … never affects a verdict"*, which is true of asterisks and false of the
+class. That RESULT has been corrected; this row is the defect it was wrong about.
+
+**It did not cause `TASK-226`'s phantom row.** That elimination rests on the
+render fixed-point check — `render(parse(f)) == f` on both actual files, 0
+unreadable — which the reviewer reproduced independently and calls a **complete
+detector for the whole class**. The conclusion there is safe; the argument
+offered for it was not.
+
+## Deliverable
+
+**A decorated row cannot silently become a declaration.** Either:
+
+- the reader **refuses a row it cannot round-trip** — `render(parse(row)) == row`; or
+- decoration is stripped **only where a documented rule says it may be**, and
+  every other shape is **reported as unreadable** rather than parsed.
+
+`ConformanceRecord` already distinguishes `unreadable` from `absent` and from
+`declared`. **That distinction is where this belongs** — the reader is already
+built to say "I could not read this row" and currently does not use it here.
+
+## Verification — V4
+
+1. Plant each of the three live traps — **backticked path, indented row, fenced
+   row** — on a copy and show each is **refused or reported**, not parsed as a
+   declaration.
+2. Plant one, then run a legitimate `perry-conform declare`, and show the
+   decorated row is **not laundered** into a canonical one.
+3. **Mutation**: revert the guard and show a **NAMED test goes red for each of
+   the three shapes** — not one test covering all three.
+4. Confirm the **asterisk** case still behaves as it does today. A bolded
+   `| **File** |` header row was once read as a declaration and `squash` already
+   answers that; do not regress it.
+5. Baselines name **both the runner and the tree** — see `TASK-233-spec.md § 4`
+   for the current numbers.
+
+## Out of scope
+
+**Converting the file to `.perry/conformance.jsonl`.** That is `TASK-234`,
+blocked on `TASK-050`, and it would **dissolve** this defect rather than fix it.
+This row must not wait on it: the hole is live under the enforce gate today and
+`TASK-234` has no date.
+
+## One coordination note
+
+`viewer/parsers.py` is also touched by `TASK-050` (header folding, in V4 review at
+`b5e7be3`) and was touched by `TASK-235` (already merged, which replaced
+`parse_decisions` wholesale). `read_conformance` is a different function from all
+of those. Keep the edit inside it, and say so in the RESULT if that turns out not
+to be possible.
+
+
+---
+
+## Correction, 2026-08-30 — the attribution above was mine and it was wrong
+
+The original wording of the deliverable said the round trip was one
+`"which the reviewer showed is a complete detector for this class"`. **The
+TASK-226 reviewer showed no such thing about a per-ROW check.** Its detector was
+`render(parse(f)) == f` over the **whole file**, and that claim was true as
+written. The per-row form is mine, invented in this spec, and I attached
+somebody else's proof to it.
+
+The cost was not theoretical. TASK-241's author inherited the sentence, built the
+per-row round trip, discovered by measurement that it does **not** close a fenced
+row — a fenced row is byte-for-byte identical to a genuine one, so no row-local
+property can see it — and reported that as *correcting the reviewer*. It was
+correcting me. The reviewer's file-level claim was never contradicted.
+
+Both halves of that are worth keeping. The **row-local invisibility** result is
+sound and provable and was measured (mutation M2), and it is a real contribution.
+The **attribution** was false, and it travelled through a spec, a RESULT and a
+commit message before a second reviewer caught it.
+
+The rule this spec should have followed: **a specification may state a property
+it wants; it may not attribute that property to somebody who did not state it.**

+# TASK-241 — V4 review
+
+# FAIL
+
+**Shape 3 of the three the spec names is not closed.** A row inside a code
+fence still becomes a real declaration, and is still laundered into a canonical
+row by the next legitimate `declare`, whenever the fence is **nested** — which
+is the ordinary way a markdown document shows a fenced block. The mechanism the
+author added is a naive open/close **toggle**, not markdown's fence rule, and it
+is defeated by the same shape it was written for.
+
+Everything else in the RESULT is true. I reproduced all five headline claims —
+end to end on both trees, the three controls, all seven mutations, the asterisk
+pin, and both archive baselines — and every one matched. The defect below is the
+only reason this is not a PASS, and it is fixable in ~10 lines inside the same
+function (measured, below).
+
+---
+
+## 1 · The defect
+
+Reviewer's tree: `git archive` copy of `8c34973` at
+`…/scratchpad/rv241/rv241-branch`. Nothing was run against
+`/Users/bytedance/proj/Perry`, against the reviewed worktree, or against any
+other worktree; the reviewed worktree is still clean (`git status --porcelain
+--untracked-files=all` → 0 lines) and `viewer/parsers.py` is still
+`039882edd56bb9ad63fb42c9a0d27de0`.
+
+`viewer/parsers.py:377`
+
+```python
+_FENCE = re.compile(r"^\s*(?:`{3,}|~{3,})")
+...
+if _FENCE.match(line):
+    in_fence = not in_fence
+    continue
+```
+
+`in_fence` is a boolean toggled by **any** fence-looking line. CommonMark says a
+fenced block is closed only by the **same delimiter character**, at **at least
+the opening run length**, with **nothing after it**. So every line that looks
+like a fence but is really *content inside* a longer or differently-charactered
+fence flips the toggle off, and the rows after it are read as declarations
+again.
+
+### Reproduction
+
+`scratchpad/rv241/rv241-nested.py` — a synthetic `mktemp` project, the branch's
+own `bin/perry-conform`, `PERRY_HOME` and `PERRY_CONFORMANCE` unset, record =
+the branch's own `HEADER` plus the body shown.
+
+```
+$ python3 rv241-nested.py $PWD/rv241-branch
+  plain fence (the tested shape)                -> undeclared  unreadable=1
+  tilde fence wrapping a backtick fence         -> conformant  unreadable=0
+  4-backtick fence containing a 3-backtick line -> conformant  unreadable=0
+  backtick fence wrapping a tilde fence         -> conformant  unreadable=0
+  fence with info string ```markdown            -> undeclared  unreadable=1
+```
+
+The three middle bodies are, verbatim:
+
+```
+~~~                                     ````                    ```
+```                                     ```                     ~~~
+| BOARD.md | 2 | 2026-08-28 | declare | | BOARD.md | 2 | … |    | BOARD.md | 2 | … |
+```                                     ````                    ~~~
+~~~                                                             ```
+```
+
+In all three, the row is **inside a fenced code block** by CommonMark's rules —
+a person reading the file sees example text — and `read_conformance` reads it as
+a declaration. `BOARD.md` flips to **conformant**, `unreadable=0`. This is the
+spec's trap 3, un-refused and un-reported.
+
+### And the laundering comes back with it
+
+`scratchpad/rv241/rv241-nested-launder.py`, branch tree, tilde-wrapping-backtick
+body, then a legitimate `perry-conform declare .perry/hook.md`:
+
+```
+--- record BEFORE ---
+~~~
+```
+| BOARD.md | 2 | 2026-08-28 | declare |
+```
+~~~
+declare rc = 0
+--- record AFTER ---
+| .perry/hook.md | 2 | 2026-08-30 | declare |
+| BOARD.md | 2 | 2026-08-28 | declare |
+```
+
+That is the whole measured harm of TASK-226/TASK-241 — verdict flip plus
+laundering into a plain canonical row nothing downstream can tell from a real
+one — still live on the branch, on the file that gates every write under
+ADR-004's enforce gate.
+
+### It is fixable inside the same function
+
+I sketched CommonMark's rule (record the opening run; close only on the same
+character, length ≥ opener, nothing after) in a throwaway copy
+(`scratchpad/rv241/rv241-fix`, ~10 lines, all inside `read_conformance` plus one
+capture group on `_FENCE`):
+
+```
+  plain fence                                   -> undeclared  unreadable=1
+  tilde fence wrapping a backtick fence          -> undeclared  unreadable=1
+  4-backtick fence containing a 3-backtick line  -> undeclared  unreadable=1
+  backtick fence wrapping a tilde fence          -> undeclared  unreadable=1
+  fence with info string ```markdown             -> undeclared  unreadable=1
+```
+
+with `tests/test_conformance.py` + `tests/test_one_header_rule.py` still
+`Ran 71 tests … OK`. So the deliverable is reachable without widening scope, and
+the sketch is offered only as evidence that it is — the author should write
+their own, plus a named test per nested shape.
+
+**The author declared this exact gap** (§ 8: *"I did not verify the fenced-row
+behaviour against a nested or info-stringed fence"*). Declaring it does not
+discharge it: it is not an edge outside the deliverable, it is the deliverable's
+third named shape.
+
+---
+
+## 2 · The two-mechanisms argument — adjudicated
+
+**(a) Is the fenced row invisible to any row-local property? Yes — provably, and
+the author is right to have measured rather than argued it.** If the fenced row
+is byte-identical to a genuine one, any function of the row alone returns the
+same value for both; there is nothing to discuss. M2 and M3 are the measurement
+and I reproduced both: with the round trip in and fence tracking out, the fenced
+trap parses and only the fenced test reddens. M1 reddens backticked, indented
+and laundering and leaves fenced green. The two mechanisms redden **disjoint**
+sets, and a single test over all three shapes would genuinely have concealed
+that. This part of the claim is sound and well-earned.
+
+**(b) Is the whole-file alternative foreclosed by the two-definitions argument?
+No. That argument is weak, and the conclusion is right for reasons the author
+did not give.**
+
+`HEADER` lives in `bin/perry-conform:405`. `render_row` lived in
+`viewer/tables.py` and both the writer and the reader import it — which is
+precisely the author's own defence of the round trip ("the canonical form is
+`render_row`, the same writer the record's only writer uses, so *what a
+declaration looks like* still has exactly one definition"). Hoisting `HEADER`
+into `viewer/tables.py` is the identical move and also leaves exactly one
+definition. The objection is about where a constant currently sits, not about
+structure, so it does not foreclose anything.
+
+The whole-file fixed point **is** the wrong reader rule, for two reasons neither
+agent stated:
+
+1. **All-or-nothing.** `render(parse(f)) == f` fails on one stray blank line,
+   one hand-added note, one older header wording — and then *every* declaration
+   in the file is void at once and the enforce gate shuts on the whole project.
+   The per-row property degrades: one bad row, one refusal, the rest still
+   declare. On a file whose own header says *"Delete a row to withdraw a
+   declaration"*, that difference is decisive.
+2. **Version coupling.** `HEADER` is prose citing ADR-004 § 4 and has been
+   reworded before. A whole-file fixed point makes every record in the wild
+   unreadable the day it is reworded again.
+
+**(c) A third framing neither agent found.** Require the row to be **inside the
+declaration table** — a contiguous run of rows following the `| File | … |`
+header and its `|---|` delimiter. It is still contextual, so it does not touch
+(a); but it uses only the column names the reader already knows (no `HEADER`
+prose, no second definition), it needs no fence bookkeeping at all, and it is
+immune to the defect in § 1 — a row separated from the header by a fence line is
+not in the run, whatever the fence nesting. It also has no "unclosed fence
+swallows the file" behaviour. If this is revisited, that is the framing I would
+take rather than patching the toggle.
+
+**(d) On "corrects the TASK-226 reviewer" — the substance is right, the
+attribution is not.** The TASK-226 reviewer wrote `render(parse(f)) == f` over
+whole files and called *that* a complete detector, used forensically on two
+actual files; as stated it was true, and it does catch the fence. The string
+`render(parse(row)) == row` appears not in the review but in
+`TASK-241-spec.md § Deliverable`, which transposed the reviewer's file-level
+check into a row-level reader rule and carried the "complete detector"
+endorsement across with it. The author corrected a real error and named the
+wrong author for it. The RESULT's own next paragraph concedes the review's check
+was file-level, so it is mis-aimed rather than self-contradictory — but the
+opening sentence of § 1 should say *the spec*, not *the review*.
+
+---
+
+## 3 · Claims verified
+
+### Claim 1 — end to end on both trees. **Reproduced exactly.**
+
+`scratchpad/rv241/rv241-e2e.sh`, my own script, synthetic `mktemp` projects,
+each tree's own `bin/perry-conform`, `PERRY_HOME`/`PERRY_CONFORMANCE` unset.
+
+```

+  laundering: after a legitimate declare of .perry/hook.md:
+      | .perry/hook.md | 2 | 2026-08-30 | declare |
+```
+
+Every figure in the RESULT's § 2 table matches, including the asterisk asterisk:
+`undeclared, unreadable=0` on both trees.
+
+### Claim 2 — three tests, three controls, and **the controls can fail**. Verified.
+
+`tests.test_conformance.TestADecoratedRowIsNotADeclaration` → `Ran 7 tests … OK`
+on the branch archive.
+
+I made the fixture harmless in the way the brief names — the reader simply stops
+reading (`return rec` inserted at the top of the row loop) — and the controls
+fired:
+
+```
+FAILED (failures=6)
+FAIL: test_an_indented_row_is_not_a_declaration
+  … assert_trap_would_have_worked …
+  AssertionError: Tuples differ: ('undeclared', 0) != ('conformant', 0)
+  : the control row no longer declares BOARD.md — the three tests below would
+    pass for the wrong reason
+```
+
+All three controls red, plus laundering, asterisk, header and real-record. These
+controls are not decorative.
+
+### Claim 3 — seven mutations. **All seven reproduced**, harness
+`scratchpad/rv241/rv241-mutate.py` (restores from a pristine copy and re-checks
+`md5 039882edd56bb9ad63fb42c9a0d27de0` before every mutation).
+
+| # | mutation | red |
+|---|---|---|
+| M1 | `if canonical != line:` → `if False:` | backticked, indented, laundering (3) |
+| M2 | `if in_fence:` → `if False:` | **fenced only** (1) |
+| M3 | `if _FENCE.match(line):` → `if False:` | **fenced only** (1) |
+| M4 | the `unreadable.append` → `pass` | backticked, indented (2) |
+| M5 | `squash(rel)` → `rel.strip("` ").lower()` | `…_bolded_header_row_is_still_not_a_row`, plus `test_one_header_rule` `test_a_bolded_header_is_not_reported_as_a_broken_row` and `test_decoration_on_the_header_changes_nothing` (3) |
+| M6 | `strip("` ")` → `strip("`* ")` | asterisk pin only (1) |
+| M7 | canonical version `int(ver)` → `int(ver) + 1` | 7 red |
+
+Spot-checked in depth: M2 and M3 (the disjointness that is the § 1 argument),
+M6 (the over-fix pin), M7, and the M7 → control-clause claim. M7 on the
+backticked test alone reddens at `assert_trap_would_have_worked`, line 1257 —
+the **control clause**, exactly as claimed, not the assertion under it.
+
+M5's two `test_one_header_rule` failures are the two the RESULT names, so
+§ 7's claim that `TestTheFifthCopy` kept its power after the fixture was
+de-backticked is **verified**, not asserted.
+
+### Claim 4 — the asterisk case. **Not regressed.**
+Byte-identical on both trees end to end; `test_an_asterisked_path_reads_exactly_as_it_did_before`
+green and reddened only by M6; the bolded `| **File** |` header still squashed
+to `file` and skipped before the guard, so it is not reported as an unreadable
+row; `TestTheFifthCopy` green.
+
+### Claim 5 — baselines. **Both archives reproduced on my host.**
+
+```
+git archive copy of main @ d2467fc   · bash tests/run · 100 modules · 2992 tests · 174.0s · 3 failures in 2 modules
+git archive copy of branch @ 8c34973 · bash tests/run · 100 modules · 2999 tests · 162.8s · 3 failures in 2 modules
+```
+
+Same three failures in both, all pre-existing on `main`:
+`test_diagnose.…test_the_queue_register_reconciles_with_the_queue_on_this_repository`,
+`test_diagnose.…test_perry_itself_passes_its_own_id_checks`,
+`test_kr_progress_provenance.…test_no_current_in_the_payload_claims_to_be_a_measurement`.
+`+7` is exactly the seven added.
+
+`python3 -m unittest discover -s tests` on the same branch archive:
+`Ran 2999 tests in 822.470s`, `FAILED (failures=6, skipped=4)` — same test
+count as `bash tests/run`, exactly **+3**, and the three extra are exactly the
+`test_risks_store.TestTheReadersAreOneFunction` double-import artefact the brief
+names (`…_the_bullet_and_placeholder_rules_are_one_object`,
+`…_the_columns_are_one_list`, `…_the_register_header_predicate_is_one_object`).
+Reproduced in full.
+
+Per the brief I treated the predicted **5** as a stale number and did not chase
+the 3-vs-5 gap. The author's decision not to chase it was right.
+
+---
+
+## 4 · Second finding — one guard the author wrote **does** survive its own deletion
+
+RESULT § 4: *"Nothing I wrote can be deleted with the suite unchanged."* That is
+false for one line.
+
+```python
+try:
+    canonical = render_row([rel, str(int(ver)), declared, route or "declare"])
+except UnrenderableCell:
+    canonical = None
+```
+
+Neutralising the `except` (so an `UnrenderableCell` propagates) leaves
+`tests.test_conformance` + `tests.test_one_header_rule` at `Ran 71 tests … OK`.
+
+And it is **reachable**, not dead code: `read_conformance` splits on `"\n"`,
+while `render_row` refuses via `line_break_at`, which uses `str.splitlines()` —
+eleven boundaries, not one. A path cell containing `U+2028` (or `\v`, `\f`,
+`\x85`, `\x1c`) sits inside a single `"\n"`-delimited line and makes `render_row`
+raise. Measured, `scratchpad/rv241/rv241-u2028.py`:
+
+```
+--- branch, guard present ---  rc = 0, clean JSON status
+--- guard neutralised ---      rc = 1
+    tables.UnrenderableCell: cell 0: contains a line break — a markdown table row is one line
+```
+
+So the guard turns a **crash of the enforce-gate tool on a hand-edited record**
+into an `unreadable` report — genuinely load-bearing, newly introduced by this
+change (no `render_row` call existed on `main`), and covered by no test. Not on
+its own a blocker: the guard is present and correct, and the direction is safe.
+It should get a named test, and § 4's sweep claim should be corrected.
+
+---
+
+## 5 · Rulings on the five declared limits
+
+**1 · Three lines outside `read_conformance` — justified, all three.**
+The import is unavoidable. `_FENCE` at module level beside `_CONFORMANCE_ROW` is
+the right place (compiled once) and matches the file's existing shape. The
+`test_one_header_rule` fixture change was forced by the new refusal, is on a
+class whose subject is the *header*, and M5 proves the class kept its power. The
+spec asked for the edit to stay inside the function and to say so if it could
+not; the author said so, and the three are the minimum.
+
+**2 · The TASK-050 merge conflict — characterisation verified.**
+`b5e7be3` changes exactly two lines that TASK-241 also touches:
+`from tables import header_index, split_row, squash` (line 43) and, inside
+`read_conformance`, `squash(rel)` → `header_index([rel]).column("file", "path") == 0`.
+Two textual conflicts, both mechanical; the resolutions the RESULT gives are
+correct, and the semantics are orthogonal (which cell is the header vs. whether
+a non-header row is canonical). The warning that M5's anchor text must be
+re-pointed after the merge is right and worth keeping.
+
+**3 · `TestTheFifthCopy.probe` de-backticked — the test kept its power.**
+Verified by M5, not by assertion: `Ran 19 tests … FAILED (failures=3)`, of which
+two are `test_one_header_rule`'s
+(`test_a_bolded_header_is_not_reported_as_a_broken_row`,
+`test_decoration_on_the_header_changes_nothing`). Exactly the RESULT's claim.
+
+**4 · Silently deleting an unreadable row — acceptable to ship. Does not block.**
+Reproduced (§ 3 claim 1: the backticked row is simply gone after the legitimate
+declare). Ruling: it is strictly better than laundering, it is fail-closed (the
+file becomes `undeclared`, the gate refuses, the tool does not proceed on a
+false verdict), and the row is **reported by `perry-conform status` before** the
+declare, so it is not silent to a user who looks. Against that, the file's own
+header invites hand editing and the set this bites has grown from one shape to
+at least six (the four the author names plus the two nested-fence directions),
+and `declare` itself prints no warning. That is a real edge and it deserves its
+own row — `declare` should either carry unreadable rows through the rewrite or
+refuse to rewrite while any exist. The author's two judgements are both correct:
+do not widen scope here, and do not file it (the PMO owns the board). It is not
+a ship blocker.
+
+**5 · Newly unreadable shapes without named tests — none of them blocks.**
+`>4` cells, `07`, empty route cell, trailing whitespace: all consequences of the
+one property and all in the safe direction. CRLF genuinely unaffected —
+`Path.read_text` applies universal newlines. The unclosed fence swallowing the
+rest of the file is fail-closed, loud through `unreadable`, and acceptable
+untested by name. **The nested fence is a different matter and it is not part of
+this limit** — it is fail-**open**, it is the deliverable's own shape 3, and it
+is § 1's FAIL. Note also that trailing-whitespace-unreadable composes with limit
+4: a stray trailing space on a genuine row now silently deletes that declaration
+at the next declare. Fail-closed, so still not a blocker, but it belongs in the
+same row as limit 4.
+
+---
+
+## 6 · Green-for-the-wrong-reason sweep — clean
+
+Checked each named mode against the seven new tests and the changed fixture:
+
+- **Vacuous fixture (zero rows parsed).** Closed by the three controls, which I
+  proved can fail (§ 3 claim 2).
+- **A test grepping its own source for a phrase in its own docstring.** None of
+  the seven reads source or docstrings; all read `perry-conform status`/`verdict`

+- **Substring assertion over a whole file reading its own comment.** The only

+`git status --porcelain --untracked-files=all` is empty — before and after my
+work. Every mutation, plant and suite run happened in `git archive` copies or
+`cp -R` copies under `scratchpad/rv241/`. No write-side Perry tool was run
+against `/Users/bytedance/proj/Perry` or any worktree; `perry-conform declare`
+ran only against `mktemp` projects; `setup` was never run; no identifier was
+minted.
+
+## 8 · Not checked
+
+- **The live branch worktree baseline (`wt-241`, 100·2999·3).** It needs the six
+  stores minted, which is a write. I measured both `git archive` copies instead
+  and they agree with the RESULT, so the branch-vs-main comparison holds; the
+  archive-equals-live-worktree claim is the author's alone.
+- **`main`'s suite on a live-board tree.** Same reason.
+- **The `perry-conform status` human (non-`--json`) rendering** of the new

+- **CommonMark conformance beyond the five fence shapes in § 1** — e.g. a fence
+  indented four or more spaces (an indented code block, which `_FENCE` treats as
+  a fence), or a backtick fence whose info string contains a backtick. Both are
+  more corners of the same mechanism; fixing § 1 properly should sweep them.
+- **`discover` on `main` or on a live worktree.** Only the branch archive.

+# TASK-243 — a count-preserving substitution destroys canonical records silently
+
+**Branch** `coding/task-243-substitution`, forked from `main` at `49d83fc`.
+
+**The ending: a substitution is a legitimate hand edit that Perry REPORTS
+loudly.** The third of the three the row offered, and it is not the fallback —
+the other two are refuted below by measurement and by reading, not by taste.
+
+**Nothing was added to `refuse_to_shrink`.** It is a count rule, USER-906 chose
+it as one, 32 to 32 is not fewer, and it is correct as a count rule. The
+question this row settles is IDENTITY, it lives in its own functions, its only
+consumer is a report, and `TestTheInvariantIsStillACountRule` asserts
+behaviourally that the invariant still permits every equal-count write on every
+register and every command name.
+
+---
+
+## 0. Where everything was run
+
+Every write-side run in this document was on a **copy**. Nothing in
+`/Users/bytedance/proj/Perry` was written to; its `perry/` and `.perry/` were
+`cp -R`'d to `scratchpad/rj243/state-perry{,-dot}` and every reproduction ran
+against a fresh copy of those. No `git checkout`, `stash`, `reset` or `clean`
+in the worktree. All harness and probe files are prefixed `rj243_` and live in
+`scratchpad/rj243/`, outside the repository.
+
+`bash tests/run` writes Perry state into the repo it runs in (TASK-249, not
+mine), so **it was never run in the worktree** — both baselines ran on
+`git archive` extractions in scratch, which is also why the mutation harness
+has its own throwaway git repo (`m_tree`) to refuse a dirty tree against.
+
+---
+
+## 1. Which ending, and why the other two are not it
+
+The row named three defensible endings. Two of them are answered by evidence I
+gathered before choosing, not by preference.
+
+### (a) "a register record carries an identity the board row can be matched against" — REFUTED BY MEASUREMENT
+
+**Two of the three registers already do, and it did not save them.** `asks` and
+`risks` are keyed on `USER-nnn` / `RX-nnn`; the id is in the store, the id is in
+the board's first column, and the two can be matched trivially. On `main` at
+`49d83fc`, on this repository's own data:
+
+```
+### asks / ordinary `ask` write
+  lint before : · ask store: 13 record(s), 6 ask(s) drifted
+  rc          : 0
+  | perry-task: wrote USER-910 (ask) → tasks.jsonl + asks.jsonl + journal + BOARD.md + event
+  records     : 13 -> 14
+  LOST        : 3   GAINED: 4
+  lint after  : · ask store: 14 record(s), 0 ask(s) drifted
+```
+
+Three canonical records with perfectly good identities destroyed at rc 0. So
+the missing half was never the identity. It was that **nobody compared the two
+sets across a write, and nobody said anything when they differed.** Adding an
+identity to `intake` — an id column on `## Intake`, a minted key in
+`intake.jsonl`, a migration — buys the thing `asks` already has and that `asks`
+has just been shown not to be saved by. It is also round 2's door by name.
+
+Identity is *necessary* and this row does add it (`REGISTER_IDENTITY`). It is
+not *sufficient*, and shipping it as the answer would have been the sixth
+predicate wearing a schema change.
+
+### (b) "the drift report becomes per-record rather than per-count" — REFUTED BY READING
+
+**It already is per-record.** `bin/perry-lint § check_intake_store_drift` joins
+`stored` and `live` on `order` and emits one finding per differing row;
+`check_ask_store_drift` and `check_risk_store_drift` join on the id.
+`DRIFT_ROWS_SHOWN` caps the printed list and explicitly does not cap the count.
+The `10 row(s) drifted` in the reproduction is already a per-record census of
+ten records.
+
+The count falls to zero after the write for a reason no granularity change
+touches: **the board and the store genuinely agree afterwards.** The write made
+them agree by throwing one of them away. A drift report is a disagreement
+census, and a disagreement that has been resolved is honestly zero. Making it
+"more per-record" changes nothing about the moment the records die.
+
+### (c) "a legitimate hand edit Perry should REPORT loudly" — CHOSEN, and the choice is FORCED
+
+The reviewer's argument was that no tool path reaches this, so it is a hand-edit
+path, and Perry reports hand edits rather than refusing them. That argument is
+true but it is weaker than it needs to be, and it has a live counter-example:
+**Perry already refuses a hand edit on this exact surface.** Hand-delete ten
+`## Intake` rows and the next write is refused (USER-906). So "Perry never
+refuses a hand edit" is not a fact about this register, and the asymmetry looks
+indefensible at first sight — delete ten rows, refused; delete ten and add ten,
+allowed.
+
+The reason it is nevertheless right is structural, and it is why I am recording
+it as forced rather than conventional:
+
+> **On `## Intake` a record's identity IS its text.** There is no id column.
+> Fixing a typo in a Request cell and swapping a row out from under a stored
+> record are **the same edit at the set level** — one identity leaves, one
+> arrives, at the same position, at equal count. No predicate can separate
+> them, because the information that would separate them was never written
+> down.
+
+A refusal would therefore hard-block a typo fix, and would name
+`perry-tasks intake-write --from-board` as the remedy for correcting a
+spelling. That is **TASK-095 round 5's defect exactly** — a widened refusal
+hard-blocking three ordinary hand-edit workflows — and this row's whole history
+is about not repeating a move that has already failed.
+
+A tool that cannot tell the two apart must say what it sees and let the person
+who made the edit decide. That is `ADR-007`'s posture and
+`perry-state § reconcile_drift`'s, and here it is the only honest option rather
+than the conventional one.
+
+### The fourth ending I considered and rejected
+
+**"A register write must not honour board rows it did not address."** This is
+`ADR-007` applied literally: for `tasks.jsonl` a board hand edit is drift that
+`perry-lint` reports until somebody renders, and it is never silently honoured.
+For the three registers, `register_change` derives from the board and the next
+write honours whatever is there. Under this ending the substitution would stay
+drifted — the drift report would literally not fall — and no record would die.
+
+I rejected it and the reason is blast radius, not difficulty. `intake` is keyed
+on POSITION, so "carry the stored record forward for every unaddressed key"
+fights the renumbering a hand insert produces, and the rule would silently stop
+persisting ordinary board edits that work today on all three registers. That is
+a behaviour change to every register write, proposed on a row whose parent
+failed five V4 rounds by moving one question one step at a time. It is a
+candidate for its own spec with its own decision, not a thing to smuggle in
+here. It is in § 7.
+
+---
+
+## 2. What shipped
+
+`bin/perry-task`, four additions and one deletion. None of them is inside
+`refuse_to_shrink` and none of them can gate a write.
+
+| symbol | what it is |
+|---|---|
+| `REGISTER_IDENTITY` | one identity per register — `id` for `asks`/`risks`, `(request, arrived)` for `intake`. Quantified over `REGISTER_SPEC` by a test, so a fourth register cannot arrive without one. |
+| `substituted_away(key, current, records)` | the stored records this write does not carry forward, matched as a **multiset**. Returns a list. Gates nothing. |
+| `substitution_report(key, path, lost, declared, dry_run)` | the loud line, or `None` when every loss was declared. `declared_removal(event)`'s number is subtracted, so an ordinary `intake-sweep` does not cry wolf. |
+| `SUBSTITUTION_RECORDS_SHOWN = 5` | caps the printed list, never the count. |
+| *(deleted)* | `carry_forward_is_addressable`'s local `identity = lambda …` — it now reads `REGISTER_IDENTITY`, so the two consumers of "the same request" cannot come apart inside one write. |
+
+`register_change` returns `(path, text, key, count, lost)` and `commit()` does
+three things with the fifth element: prints the report to **stderr** after
+`replace_canonical_pair` lands (past tense, so a report of a destruction that
+then failed is impossible), puts it in the plan under
+`register_store.substituted` so a `--json` caller with no stream still gets it,
+and writes it into the **event** so there is a way back and not only a warning.
+`--dry-run` previews the same line in the future tense before returning.
+
+The message, run for real:
+
+```
+perry-task: wrote RX-902 (risk-add) → tasks.jsonl + risks.jsonl + journal + BOARD.md + event
+perry-task: ⚠ 2 canonical risks record(s) did not survive this write, and the
+board carries no row for them: RX-003; RX-004. Nothing removed them —
+`## Top risks` was edited by hand so that the rows they were derived from are
+gone, and this write persisted that edit. The count did not fall, so USER-906's
+invariant is silent here and `perry-lint` will now report `0 row(s) drifted`
+against risks.jsonl: the disagreement is real and it has just been resolved in
+the board's favour. The lost records are in the `substituted` field of this
+write's event in `.perry/events.jsonl`. To put them back, restore the rows on
+`## Top risks` and re-run `perry-tasks risks-write --from-board`. That is the
+same board-to-store direction `refuse_to_shrink` names, and it is gated.
+```
+
+### The property, stated so it can be falsified
+
+The row's wording is *"the drift report must not decrease while canonical
+records are being destroyed."* Made precise:
+
+> **A canonical record may not leave a register store unreported.** For any
+> register-touching write, the number of stored records the write does not
+> carry forward, less what the command declared it removes, is named by the
+> write itself, at the moment it happens, and equals the number actually lost.
+
+Before this change the operator's sequence was `10 drifted → (silence) →
+0 drifted`. After it, the middle term is a count and a list of the records.
+
+**The literal wording does not hold and I am not claiming it does.** The lint
+drift line still falls to zero — see § 3's AFTER column — because after the
+write the board and the store really do agree, and a disagreement census that
+reported a resolved disagreement would be lying in the other direction. Making
+`perry-lint` itself carry the loss forward needs a durable "somebody has seen
+this" surface with a clearing condition, and I did not build one. That is § 7,
+recorded as not closed rather than quietly redefined.
+
+---
+
+## 3. The reproduction, before and after, on all three registers and the `zh` fixture
+
+Board state for every number below: a `cp -R` of `/Users/bytedance/proj/Perry`'s
+`perry/` and `.perry/` **as of 2026-08-30 08:55** — 37 intake records, 13 ask
+records, 4 risk records, all at `0 drifted` before anything was touched. BEFORE
+is `main` at `49d83fc` (`bin/perry-task` md5 `377dec1cfb91e44189679055af159b50`),
+AFTER is this branch at `980c830` (md5 `23e26fc319012fa1dadfe3e1ce361615`), both
+extracted with `git archive` into scratch. The substitution is made by hand on
+`BOARD.md` — N register rows deleted, N filler rows appended — and then one
+ordinary command is run.
+
+| register · command | rc | records | LOST | GAINED | lint before | lint after | reported BEFORE | reported AFTER |
+|---|---|---|---|---|---|---|---|---|
+| intake · `resolve-intake 1` (declares 0 removals) | 0 | 37 → 37 | **10** | 10 | `10 row(s) drifted` | `0 row(s) drifted` | **nothing** | **10 named** |
+| intake · `intake --title …` (ordinary write) | 0 | 37 → 38 | **10** | 11 | `10 row(s) drifted` | `0 row(s) drifted` | **nothing** | **10 named** |
+| asks · `ask --needed …` | 0 | 13 → 14 | **3** | 4 | `6 ask(s) drifted` | `0 ask(s) drifted` | **nothing** | **3 named** |
+| risks · `risk-add --title …` | 0 | 4 → 5 | **2** | 3 | `4 risk(s) drifted` | `0 risk(s) drifted` | **nothing** | **2 named** |
+| `zh` fixture · asks · `ask --needed …` | 0 | 2 → 3 | **`USER-014`** | `USER-016`, `USER-017` | `2 ask(s) drifted` | `0 ask(s) drifted` | **nothing** | **`USER-014` named** |
+
+Verbatim, the row's own headline case, on `main`:
+
+```
+### intake / resolve-intake (declares 0 removals)
+  lint before : · intake store: 37 record(s), 10 row(s) drifted
+  rc          : 0
+  | perry-task: wrote intake row 1 (resolve-intake) → tasks.jsonl + intake.jsonl + journal + BOARD.md + event
+  records     : 37 -> 37
+  LOST        : 10   GAINED: 10
+  lint after  : · intake store: 37 record(s), 0 row(s) drifted
+```
+
+and on the branch tip, same board, same command:
+
+```
+### intake / resolve-intake (declares 0 removals)
+  lint before : · intake store: 37 record(s), 10 row(s) drifted
+  rc          : 0
+  | perry-task: wrote intake row 1 (resolve-intake) → tasks.jsonl + intake.jsonl + journal + BOARD.md + event
+  | perry-task: ⚠ 10 canonical intake record(s) did not survive this write, and
+  |   the board carries no row for them: ("measuring one tree's tool with another
+  |   tree's PERRY_HOME silently loads the wrong schema …", '2026-08-30'); … and
+  |   5 more. Nothing removed them — `## Intake` was edited by hand … To put them
+  |   back, restore the rows on `## Intake` and re-run
+  |   `perry-tasks intake-write --from-board`.
+  records     : 37 -> 37
+  LOST        : 10   GAINED: 10
+  lint after  : · intake store: 37 record(s), 0 row(s) drifted
+```
+
+The `zh` case, where the reviewer reproduced it: the fixture's queue is grown to
+two rows, `perry-tasks asks-write --from-board` mints a 2-record store,
+`BOARD.md` is declared conformant, and then `| USER-014 | 确认预发布环境的默认值 |`
+is replaced by hand with `| USER-016 | rj243 手改替换行 |` at equal count. On
+`main` the next `perry-task ask` destroyed `USER-014`'s record at rc 0 with the
+localized heading resolving perfectly well; on the tip it names it.
+
+### The register still works — no false alarm on any ordinary command
+
+The whole lifecycle on an **in-sync** copy of the live board, tip only:
+
+```
+  resolve-intake 2   rc=0  intake=37 asks=13 risks=4   substitution-report=none
+  intake-sweep       rc=0  intake=36 asks=13 risks=4   substitution-report=none
+  intake --title     rc=0  intake=37 asks=13 risks=4   substitution-report=none
+  ask --needed       rc=0  intake=37 asks=14 risks=4   substitution-report=none
+  risk-add --title   rc=0  intake=37 asks=14 risks=5   substitution-report=none
+  risk-clear RX-001  rc=0  intake=37 asks=14 risks=5   substitution-report=none
+  answer USER-909    rc=0  intake=37 asks=14 risks=5   substitution-report=none
+  · intake store: 37 record(s), 0 row(s) drifted
+  · ask store: 14 record(s), 0 ask(s) drifted
+  · risks store: 5 record(s), 0 risk(s) drifted
+```
+
+`intake-sweep` is the one that matters here: it removes a record (37 → 36) and
+those records ARE lost by identity, so without `declared_removal` subtracted
+every ordinary sweep would print a destruction notice. The event log confirms
+the field means one thing — `substituted: 0` on all seven, including the sweep.
+
+---
+
+## 4. The tests, and every control shown able to fail
+
+`tests/test_register_substitution.py` — **26 tests**, and the module reuses
+`test_register_store_invariant`'s `Fixture`, `build_board` and `REGISTERS` so
+the two rows cannot come to disagree about what a register is.
+
+**The trap.** TASK-203 round 4 shipped its bound test on a clean board where no
+shrink was possible — the one test that could not tell — and round 5 had to add
+an `assertLess` before its own control could fail. So the precondition is a
+class of its own here and it runs **before** any behaviour.
+
+`Staged.check()` asserts four things about every board this module builds:
+
+1. the store started with records (`assertGreater(len(before), 0)`);
+2. the derived count EQUALS the stored count — *"or this is a shrink and
+   `refuse_to_shrink`, not this row, is what answers"*;
+3. **exactly `n` record identities are about to be lost** — the assertion that
+   makes a substitution possible, and the one round 4 did not have;
+4. `refuse_to_shrink` is handed those two integers directly and must NOT raise.
+
+### Each control shown able to fail
+
+| control | shown able to fail by |
+|---|---|
+| `check()`'s "n identities must be about to be lost" | `test_the_control_itself_can_fail_when_no_substitution_is_staged` builds a `Staged` on an **untouched** board and asserts `check()` **raises**, matching on the message. This is the control's own control, and it is the assertion round 5 of the parent row had to add. |
+| "lint must SEE the substitution before the write" | `assertGreater(before, 0)` inside `test_the_drift_report_may_not_fall_to_zero_unaccompanied`, asserted before the command runs. A clean board scores 0 here and the test dies on the control, not on the behaviour. |
+| "the swept row IS lost by identity" | `test_an_intake_sweep_removes_records_and_is_not_a_finding` asserts `len(substituted_away(before, after)) == 1` **before** asserting the report is silent. Without it, "silent" would be green because nothing was lost — the wrong reason, indistinguishable from the right one. MS6 (`declared` no longer subtracted) reddens this test, which is the proof the control is load-bearing. |
+| "the identity really does repeat" | `test_one_of_a_duplicated_pair_deleted_by_hand_is_reported` asserts `len({identity(r)}) == 2` over 3 records first. Under set subtraction the answer is 0 and the test is red; MS4 confirms. |
+| "the board must derive FEWER records" | `test_a_shrink_is_still_refused_on_the_same_board` asserts `assertLess(derived, stored)` before running either command, so the shrink half cannot pass on a board where no shrink is staged. |
+| "the count is preserved" (zh) | asserted on `S.ask_records` before the write, so the localized test cannot silently become a shrink test. |
+| "a substitution wider than the printed cap is staged" | `test_seven_losses_are_counted_seven_and_listed_five` asserts `assertGreater(staged.n, SUBSTITUTION_RECORDS_SHOWN)` **before** anything about the message, and asserts the register is nine rows first. On a four-row board the whole test dies on the control. This is the control the first round of this module did not have, and its absence let three display-path mutations survive (§ 5). |
+| "the staged board is still a readable table" | `test_the_staged_board_is_still_a_readable_table_on_every_register` — a filler that broke the shape would be refused for a reason that has nothing to do with this row. |
+
+### What the 25 cover
+
+* **all three registers**, quantified over `REGISTERS` — the report fires, names
+  the count, names each lost record, names the heading, names the way back;
+* **the `zh` localized queue** (`## 用户输入队列`), where a report resolving its
+  heading from an English literal would be silent;
+* **`resolve-intake`**, the command that declares 0 removals and is therefore
+  *inside* `refuse_to_shrink`'s bound — the reviewer's own reproduction;
+* **the multiset**, on both the CLI and the function, on numbers a set cannot
+  tell apart;
+* **the ordinary case**: six commands on an in-sync board report nothing, and
+  `intake-sweep` removes a record and is not a finding;
+* **the excess**: a sweep over a substitution reports `declares it removes 1
+  record(s)` and `2 of them are unaccounted for`;
+* **the way back**: `perry-tasks <key>-write --from-board` is *run for real* on
+  every register, because the refusal one function over once named
+  `perry-tasks tasks-write`, which there is no such thing as;
+* **the invariant is still a count rule**: equal counts permitted for every
+  register × nine command names; both refusal branches still fire on a real
+  shrink; the report never changes an exit code;
+* **the map is complete**: `set(REGISTER_SPEC) == set(REGISTER_IDENTITY)`, and
+  the intake identity is asserted to be the one `carry_forward_is_addressable`
+  joins on — behaviourally, through both functions.
+
+---
+
+## 5. Mutations — every one with its anchor and its named test
+
+Harness `scratchpad/rj243/rj243_mut.py`, uniquely prefixed `rj243_`. It refuses
+a dirty tree before it starts and re-checks at the end, asserts the control is
+GREEN before mutating anything, resolves each anchor at run time and **refuses a
+non-unique anchor**, clears every `__pycache__` on both sides of every
+mutation, sleeps past the whole-second boundary in both directions, restores
+from an in-memory copy of the original bytes and **md5-verifies the restore**.
+It runs against its own throwaway git repo (`m_tree`, a `git archive` of
+`980c830`), never against the worktree.
+
+Modules: `test_register_substitution test_register_store_invariant
+test_intake_store test_asks_store test_risks_store test_purge`.
+**Control: 264 tests, OK, 90.2 s.** Every row restored to
+`23e26fc319012fa1dadfe3e1ce361615`, and the harness reported `tree clean at
+exit`.

+
+### The three the V4 review found alive, and the test that kills them
+
+The first round of mutations missed a whole branch. `SUBSTITUTION_RECORDS_SHOWN`
+is 5 and every board in the module staged at most **3** losses, so the
+`len(lost) > 5` path was never reached and three mutations inside it survived —
+including the one whose docstring names this row's own failure mode.
+
+| # | anchor | mutation | first round | with `WIDE_INTAKE` |
+|---|---|---|---|---|
+| **MS10** | `f"⚠ {len(lost)} canonical {key} record(s) {verb} this write, and the "` | `{len(shown)}` — **the report announces 5 destroyed records when 10 died** | **GREEN — SURVIVED** | **RED** · `test_seven_losses_are_counted_seven_and_listed_five` |
+| MS11 | the `", and {…} more"` tail | `tail = ""` | **GREEN — SURVIVED** | **RED** · same test |
+| MS12 | `verb = "would not survive" if dry_run else "did not survive"` | always `"would not survive"` | **GREEN — SURVIVED** | **RED** · same test |
+
+I re-measured the survivals myself rather than taking them: each of the three
+applied to `980c830` and `test_register_substitution` run alone gives
+**`Ran 25 tests … OK`** on all three, `bin/perry-task` restored and md5-verified
+between each. The reviewer measured the same three green across a wider module
+set (71 tests).
+
+`WIDE_INTAKE` is a nine-row `## Intake`, so seven records can be destroyed in
+one write: five named, two summarised, **seven counted**. The test asserts the
+count is 7 and not 5, that exactly `SUBSTITUTION_RECORDS_SHOWN` identities are
+named, that the tail says `and 2 more`, and that a real write is in the past
+tense — with a control, `assertGreater(staged.n, SUBSTITUTION_RECORDS_SHOWN)`,
+so a board narrower than the cap dies on the control instead of passing.
+
+The shipped code was right the whole time and its own reproduction measured it
+in exactly that regime — 10 destroyed, `⚠ 10 canonical intake record(s)`, `… and
+5 more`. What was missing was the regression test, and it is four assertions
+wide.
+
+Second harness run, on `b96ab35` in its own throwaway git repo:
+**control 265 tests, OK, 73.0 s**; MS10, MS11 and MS12 each **RED with one
+named failure**, `test_seven_losses_are_counted_seven_and_listed_five`, and
+`tree clean at exit`.
+
+**Thirteen of thirteen died. None survived.** Every verdict above is carried by at least
+one **named behavioural** test that drives `perry-task` through the CLI on a
+board where a substitution is possible — not by an assertion about a constant,
+which is the failure mode TASK-203's `MR` demonstrated at round 4.
+
+---
+
+## 6. Baselines — runner, tree AND hour
+
+Both on `git archive` extractions in `scratchpad/rj243/`, never in the worktree,
+so `bash tests/run`'s four state writes (TASK-249, not mine) landed in scratch.
+
+| runner | tree | hour | result |
+|---|---|---|---|
+| `bash tests/run` | `main` @ `49d83fc`, `bin/perry-task` md5 `377dec1cfb91e44189679055af159b50` | 2026-08-30 **09:07–09:13**, load ~10 | **103 modules · 3098 tests · 341.5 s · 8 workers · 3 module(s) red, 4 failures** |

+```
+
+That is the brief's `103 / 3098 / 4` reproduced on `main` by my own measurement,
+and the same four on the tip. None touches a register store. The fourth
+(`test_heading_title`) fails on `('TASK-050', 'V4 review — TASK-050 / 053 / 057
+/ 060')`, a legitimate multi-row evidence document — filed, not this row's. Two
+of the four are data-dependent on board state; I measured both trees against the
+same committed `perry/`, so the comparison is like for like.
+
+---
+
+## 7. What I could not close
+
+0. **THE COST OF THE ENDING I CHOSE: an innocent typo fix prints a data-loss
+   warning.** This is the caveat § 7 omitted in the first draft, and the V4
+   reviewer built the case by construction — `lgoin` → `login` in a Request
+   cell, then any register-touching command: rc 0, the fix persists, and the
+   edit is **set-level identical to a substitution**, which is exactly the
+   argument in § 1(c) confirmed rather than asserted. Under REPORT, that
+   correcting of a spelling mistake now prints
+   `⚠ 1 canonical intake record(s) did not survive this write`.
+
+   **That is correct behaviour and a reader has to be told so in advance.** The
+   information that would separate a typo fix from a row swap was never written
+   down — on `## Intake` a record's identity IS its text — so Perry cannot know
+   which one it just saw, and the alternative was a refusal that hard-blocks the
+   typo fix and names `intake-write --from-board` as the remedy for a spelling
+   correction. The noise is the price of not repeating TASK-095 round 5. It is
+   bounded: the two id-keyed registers are unaffected, because editing the text
+   of a `USER-` or `RX-` row leaves its identity alone and reports nothing.
+
+   The follow-up worth its own row is narrowing it, not removing it: an intake
+   record that carries a minted key would let a text edit at a stable key be
+   told apart from a swap — which is § 7.2's question and § 1(a)'s ending
+   arriving by the back door, and it is a decision, not a patch.
+
+1. **`perry-lint`'s drift count still falls to zero across a substitution.** The
+   row's literal property — *"the drift report must not decrease while canonical
+   records are being destroyed"* — holds in the form stated in § 2 (the fall is
+   now accompanied, and the number the write prints equals the number lost) and
+   **does not hold literally**. The V4 reviewer's own words for why that is an
+   acceptable close, carried here verbatim because they are better than mine:
+
+   > *the literal wording would require lint to report a disagreement that no
+   > longer exists. The defect filed was the SILENCE, and that is closed.*
+
+   Making lint itself carry the loss forward needs a durable record of "N
+   records were destroyed and nobody has acknowledged it", and every version of
+   that I sketched has the same unsolved half: no clearing condition. A warning
+   that can never be cleared is a warning everybody learns to skip, which is the
+   same failure in a slower form. The event log now carries the records
+   (`substituted`), so the raw material for such a check exists; the surface
+   that would let it be acknowledged does not, and inventing one inside this row
+   would be the move this row's history warns against. **This is the honest gap
+   and it deserves its own row.**
+
+2. **The fourth ending — "a register write must not honour board rows it did
+   not address" — is not evaluated, only argued down** (§ 1). It is the ending
+   that would hold the literal property, it is `ADR-007` applied to the three
+   registers as it already is to `tasks.jsonl`, and it is a behaviour change to
+   every register write. It needs a decision, not a branch.
+
+3. **A substitution is still reported *after* it lands, never before.** The
+   report is in the past tense on purpose (a report of a destruction that then
+   failed would be the same class of false claim), so an operator who wants a
+   preview has to ask for one with `--dry-run`. Nothing warns at the moment the
+   board is edited, because nothing watches the board.
+
+4. **`resolve-intake <n>` still addresses a row by position on a board whose
+   positions the substitution moved.** The report says which records died; it
+   does not say that the integer the user typed now means a different request.
+   `perry-lint`'s own drift finding says exactly that, before the write. After
+   the write there is nothing left for it to say.
+
+5. **The reissued id, noted by the round-5 reviewer as "someone else's row",
+   is untouched.** On the `zh` reproduction the destroyed `USER-014` was
+   replaced and the next mint handed out a fresh id; that is `USER-909`'s
+   question about `perry-decide`, one register over, and I did not widen into
+   it.
+
+6. **Not re-run:** crash recovery at the rename boundaries (the report is
+   printed after `replace_canonical_pair` returns, so a crash inside it means no
+   report and no write — reasoned from the ordering, not probed with
+   `os._exit`); concurrency between two Perry writers; the full 3123-test suite
+   per mutation (six modules / 264 tests each, as the parent row did).
+
+7. **`risks.jsonl` on a localized board** was not driven end to end. I drove the
+   `zh` case on `asks` because that is where the reviewer reproduced it; the
+   English `risks` case is in § 3 and in the suite.
+
+---
+
+## 8. Disclosure
+
+* Nothing was written into `/Users/bytedance/proj/Perry`. Its `perry/` and
+  `.perry/` were copied out once, read-only, and every write-side run used the
+  copies. No `git checkout`, `stash`, `reset` or `clean` in the worktree.
+* `bash tests/run` was never run inside the worktree — TASK-249's four state
+  writes landed only in `scratchpad/rj243/b_main` and `b_tip`, which are
+  throwaway `git archive` extractions.
+* The mutation harness restored `bin/perry-task` to
+  `23e26fc319012fa1dadfe3e1ce361615` after every row and reported `tree clean at
+  exit`; `git status --porcelain` in the worktree carries only this file.
+* Every scratch file is prefixed `rj243_` or lives under `scratchpad/rj243/`.
+  `__pycache__` was cleared in the worktree and on both sides of every mutation.
+* The board and `perry/tasks.jsonl` were **not** updated, as instructed.

+# TASK-243 — a count-preserving substitution destroys canonical records silently, and the drift report goes DOWN as it happens
+
+> Consolidated from the board row 2026-08-30. The row's own fields are the

+
+## Why this row exists
+
+Found by the TASK-203 round 5 V4 reviewer 2026-08-30, ruled non-blocking for that row and filed here. Swap N ## Intake rows on the board by hand — same count, different rows — and any register-touching command persists the swap, INCLUDING resolve-intake, which declares 0 removals and is therefore inside its bound. Measured: 10 canonical records lost, 10 gained, rc 0, and perry-lint going from '16 row(s) drifted' to '0 row(s) drifted' as the records are destroyed. Also reproduced on asks.jsonl on the zh fixture. TASK-203's invariant does not catch it and is not supposed to: USER-906 chose a COUNT rule, and 32 to 32 is not fewer. The reviewer's reason for filing rather than blocking is the part worth keeping — closing it needs a per-record IDENTITY predicate, which is round 2's door and the fifth predicate the amendment explicitly forbids, and no tool path reaches it today because every tool-produced case is a shrink and is already refused.
+
+## Deliverable

+
+Blocked until TASK-203 lands. Start from evidence/2026-08/TASK-203-round5-v4-review.md, which carries the reproduction and the reasoning for why it was filed rather than blocked. Note the reviewer's own framing: no tool path reaches this today because every tool-produced case is a shrink and is already refused — so this is a hand-edit path, which makes 'report loudly' a serious candidate answer rather than a fallback.

+# TASK-243 — V4 review — **PASS**
+
+Reviewed `coding/task-243-substitution` @ `d889fae` (code `86aa4cf`, tests
+`980c830`, account `d889fae`) against `main` @ `49d83fc`.
+
+Everything below is my own measurement. Nothing was written into
+`/Users/bytedance/proj/Perry` or into the reviewed worktree — `git status
+--porcelain` in the worktree is empty at exit and `bin/perry-task` is still
+`23e26fc319012fa1dadfe3e1ce361615`. Every write-side run was against a
+`git archive` extraction in `scratchpad/rjrev243/` over a `cp -R` of the live
+`perry/` + `.perry/`. `bash tests/run` was run only in `b_main` and `b_tip`,
+which are throwaway extractions, so TASK-249's four state writes landed there.
+Every file I created is prefixed `rjrev_` or lives under
+`scratchpad/rjrev243/`. No `git checkout` / `stash` / `reset` / `clean`.
+
+Note: `perry/evidence/2026-08/TASK-243-spec.md` **does not exist on this
+branch** — it was added on `main` at `f92aed1`, which is not an ancestor of
+`d889fae`. I read it with `git show f92aed1:…`. Its Deliverable and Out-of-scope
+fields are `—`; the acceptance criteria are the board row's own fields.
+
+---
+
+## Verdict
+
+**PASS.** The row's declared behaviour holds under my own reproduction on all
+three registers and the `zh` fixture; the ten mutations die (I ran eight of
+them directly and reproduced the author's failure counts exactly); the
+controls are load-bearing and the control's own control is real; the invariant
+is untouched at the byte level; and the two baselines reproduce name for name
+when measured twenty minutes apart on one machine.
+
+The one thing I found that the row's own standard does not meet is a
+**surviving mutation the author did not try** — the report shortening its own
+count to fit the terminal — on a display path no test reaches. Shipped
+behaviour is correct there and I measured it correct in the >5 regime, so it is
+a coverage gap, not a defect, and it does not carry a FAIL.
+
+---
+
+## 1. The choice — ruling on each refutation
+
+### (a) "give the record an identity" — **REFUTED. Upheld by my measurement.**
+
+`asks` and `risks` already carry exactly the identity ending (a) would give
+`intake`, and on `main` it did not save them. Against a copy of this
+repository's live state, `main` @ `49d83fc`:
+
+```
+### b_main :: asks / ask --needed
+  lint before           : · ask store: 13 record(s), 6 ask(s) drifted
+  rc                    : 0
+  records               : 13 -> 14
+  LOST                  : 3   GAINED: 4
+  lost identities       : ['USER-001', 'USER-002', 'USER-003']
+  lint after            : · ask store: 14 record(s), 0 ask(s) drifted
+  REPORTED by the write : 0
+    | perry-task: wrote USER-910 (ask) → tasks.jsonl + asks.jsonl + journal + BOARD.md + event
+
+### b_main :: risks / risk-add --title
+  lint before           : · risks store: 4 record(s), 4 risk(s) drifted
+  rc                    : 0
+  records               : 4 -> 5
+  LOST                  : 2   GAINED: 3
+  lost identities       : ['RX-001', 'RX-002']
+  lint after            : · risks store: 5 record(s), 0 risk(s) drifted
+  REPORTED by the write : 0
+```
+
+Three and two canonical records with perfectly good `USER-nnn` / `RX-nnn`
+identities destroyed at rc 0 with nothing said, and the drift number falling to
+zero as it happened. The identity was present in both the store and the board's
+first column the whole time. The missing half was that nobody compared the two
+sets across the write — which is what shipped. Adding an id column, a minted
+key and a migration to `intake` would buy the thing that was just shown not to
+be enough, and it is round 2's door by name. **Refutation stands.**
+
+### (b) "make the drift report per-record" — **REFUTED. Upheld by reading and by measurement.**
+
+`bin/perry-lint § check_intake_store_drift` builds
+
+```python
+stored = {r["order"]: r for r in good}
+live   = {r["order"]: r for r in derived}
+```
+
+walks `sorted(live)`, appends one `rows` entry per differing row (plus one per
+`set(stored) - set(live)`), and sets
+`check_intake_store_drift.stats["drifted"] = len(rows)` **before**
+`DRIFT_ROWS_SHOWN` slices the printed findings. `check_ask_store_drift` and
+`check_risk_store_drift` key on the id. It is already a per-record census; the
+`10 row(s) drifted` in the reproduction is already ten records.
+
+The "genuinely agree" half is measured, not asserted: on the tip, after the
+write, `· intake store: 42 record(s), 0 row(s) drifted`. The store now IS the
+board's derivation. A disagreement census that kept reporting a resolved
+disagreement would be lying in the other direction. No granularity change
+touches the moment the records die. **Refutation stands.**
+
+### (c) "report loudly" — **CHOSEN, and I confirm the choice is FORCED.**
+
+This is the strongest claim in the row and it is the one I tested hardest. I
+built the typo fix the author says a refusal would hard-block —
+`fix the lgoin bug` → `fix the login bug` in a Request cell, equal count, same
+position — and ran it on both trees (`rjrev_zh_typo.py`):
+
+```
+[typo] tree=b_main
+[typo] store before: ['fix the lgoin bug', 'something else']
+[typo] rc=0   store after: ['fix the login bug', 'something else']
+[typo] reported=0   refused=False
+
+[typo] tree=b_tip
+[typo] store before: ['fix the lgoin bug', 'something else']
+[typo] rc=0   store after: ['fix the login bug', 'something else']
+[typo] reported=1   refused=False
+       | perry-task: ⚠ 1 canonical intake record(s) did not survive this write,
+         and the board carries no row for them: ('fix the lgoin bug',
+         '2026-08-01'). Nothing removed them — `## Intake` was edited by hand …
+```
+
+At the set level the typo fix and the substitution are the same edit: one
+identity leaves, one arrives, same position, equal count. No predicate can
+separate them, because the information that would separate them was never
+written down — `## Intake` has no id column, so a record's identity IS its text.
+A refusal would therefore hard-block a spelling correction and name
+`perry-tasks intake-write --from-board` as the remedy for it, which is
+TASK-095 round 5's shipped defect exactly. **Forced, not conventional.
+Refutation of the alternatives stands.**
+
+**Caveat the account does not state.** Under the chosen ending that innocent
+typo fix prints a data-loss notice. That is unavoidable given the argument
+above, and `perry-lint` already reports the same edit as drift before the write,
+so the report is not inventing a claim — but § 7 should say it out loud rather
+than leaving the reader to infer it from § 1. Non-blocking.
+
+### The fourth ending — **rejection ACCEPTED, with one reservation.**
+
+"A register write must not honour board rows it did not address" is the only
+ending on the table that would hold the literal property, and it is `ADR-007`
+applied to the three registers as it already is to `tasks.jsonl`. The stated
+reason for rejecting it — blast radius — checks out against the code I read:
+`intake` is keyed on POSITION (`check_intake_store_drift` and
+`carry_forward_is_addressable` both join on `order`), so "carry the stored
+record forward for every unaddressed key" fights the renumbering a hand insert
+produces, and the rule would change the behaviour of every register write on
+all three registers. On a row whose parent failed five V4 rounds precisely by
+moving one predicate at a time, deferring that to its own decision is the right
+call, and § 7.2 records it as argued down rather than evaluated.
+
+*Reservation:* it is recorded in an evidence document, not filed. § 7.1 and
+§ 7.2 both need rows; neither exists yet.
+
+---
+
+## 2. The constraint — no fifth predicate. **VERIFIED INDEPENDENTLY.**
+
+I parsed both files with `ast` and hashed the exact source segments:

+
+Byte-identical, both functions. The six lines in the diff that mention either
+name are all additions and all outside both bodies:
+
+| line | what it is |
+|---|---|
+| `#: This is NOT the invariant and it gates nothing (TASK-243). \`refuse_to_shrink\`` | `REGISTER_IDENTITY` docstring |

+
+`TestTheInvariantIsStillACountRule` also asserts this behaviourally — equal
+counts permitted for 3 registers × 9 command names, and both refusal branches
+still firing on a real shrink — which is stronger than reading the source.
+
+---
+
+## 3. Claim 1 — before and after. **REPRODUCED.**
+
+`rjrev_repro.py`, against a `cp -R` of the live `perry/` + `.perry/` taken
+2026-08-30 ~09:45 (42 intake / 13 ask / 4 risk records, all at 0 drifted before
+anything was touched). N register rows replaced by hand on `BOARD.md` at equal
+count, then one ordinary command.
+
+| register · command | rc | records | LOST | GAINED | drift before → after | reported on `main` | reported on tip |
+|---|---|---|---|---|---|---|---|
+| intake · `resolve-intake 1` (declares 0) | 0 | 42→42 | **10** | 10 | 10 → 0 | **0** | **10** |
+| intake · `intake --title` | 0 | 42→43 | **10** | 11 | 10 → 0 | **0** | **10** |
+| asks · `ask --needed` | 0 | 13→14 | **3** | 4 | 6 → 0 | **0** | **3** |
+| risks · `risk-add --title` | 0 | 4→5 | **2** | 3 | 4 → 0 | **0** | **2** |
+| `zh` · asks · `ask --needed` | 0 | 2→3 | **USER-014** | 2 | — | **0, not named** | **1, named** |
+
+The `zh` case verbatim (`rjrev_zh_typo.py`), on the localized heading
+`## 用户输入队列` with an English-language config:
+
+```
+[zh]  tree=b_main  rc=0  store after=['USER-015','USER-016','USER-017']  USER-014 destroyed=True
+[zh]  reported=0  USER-014 named in output=False
+[zh]  tree=b_tip   rc=0  store after=['USER-015','USER-016','USER-017']  USER-014 destroyed=True
+[zh]  reported=1  USER-014 named in output=True
+```
+
+I also drove the three register-touching commands the module's `ORDINARY` map
+does not cover (`rjrev_othercmds.py`, tip): `add` LOST=2 reported=2, `answer`
+LOST=1 reported=1, `risk-clear` LOST=1 reported=1. No silent loss on any of
+them.
+
+**Beyond the row's claims — the named way back actually works.** The message
+says "restore the rows on `## Intake` and re-run `perry-tasks intake-write
+--from-board`". I discharged a row (giving it `outcome` and the store-only
+`discharged: true`), substituted it away, confirmed the report and the event's
+`substituted` field carried the whole record, then restored the board row and
+ran the named command. The restored record is byte-for-byte the original,
+`discharged: true` included (`rjrev_wayback.py`, `FAITHFUL? True`). This
+matters because the refusal one function over once named a subcommand that does
+not exist; here the remedy is both a real command and a sufficient one.
+
+---
+
+## 4. Claim 2 — try to make it cry wolf. **COULD NOT.**
+
+`rjrev_wolf.py`, tip, one in-sync board, thirteen commands in sequence
+including two intakes with the **same title** (the multiset case) and three
+sweeps:
+
+```
+  resolve-intake 2   rc=0  stores=(4,4,3)  report=none
+  intake-sweep       rc=0  stores=(2,4,3)  report=none      <- removed 2 records
+  intake --title     rc=0  stores=(3,4,3)  report=none
+  intake --title     rc=0  stores=(4,4,3)  report=none      <- duplicate title
+  intake-sweep       rc=1  stores=(4,4,3)  report=none
+  ask --needed       rc=0  stores=(4,5,3)  report=none
+  answer USER-002    rc=0  stores=(4,5,3)  report=none
+  risk-add --title   rc=0  stores=(4,5,4)  report=none
+  risk-clear RX-001  rc=0  stores=(4,5,4)  report=none
+  add --title        rc=0  stores=(4,5,4)  report=none
+  resolve-intake 1   rc=1  stores=(4,5,4)  report=none
+  intake-sweep       rc=1  stores=(4,5,4)  report=none
+  purge              rc=2  stores=(4,5,4)  report=none
+  · intake store: 4 record(s), 0 row(s) drifted
+  · ask store: 5 record(s), 0 ask(s) drifted
+  · risks store: 4 record(s), 0 risk(s) drifted
+
+  FALSE ALARMS on ordinary lifecycle: 0
+```
+
+The `intake-sweep` that removed two records is the one that matters — those
+records ARE lost by identity, and `declared_removal` subtracted is what keeps
+it quiet. MS6 (below) proves that subtraction is load-bearing.
+
+I also probed the reverse — whether a command's DECLARED removal can *mask* a
+hand substitution (`rjrev_mask.py`). It cannot in any case I could reach:
+`purge` is not in `REGISTER_EVENTS`, so its constant `SHRINK_ALLOWANCE["purge"]
+= 1` never reaches a register report at all; `resolve-intake` declares 0;
+`intake-sweep` declares the count it computed from the same board, so a sweep
+over a substitution reports the excess (`n=1` → LOST=2 reported=2 with
+"declares it removes 1 record(s) … 1 is unaccounted for"; `n=2` → LOST=3
+reported=3).
+
+---
+
+## 5. Claim 3 — ten mutations. **EIGHT SPOT-CHECKED DIRECTLY, ALL RED, COUNTS MATCH.**
+
+`rjrev_mut.py` on `m_tree` (its own `git archive` of `980c830`), unique-anchor
+check, `__pycache__` cleared on both sides, mtime slept past the second
+boundary, md5-verified restore after every row. Modules run:
+`test_register_substitution` + `test_register_store_invariant`.
+**Control: 71 tests, OK.** Final md5 `23e26fc319012fa1dadfe3e1ce361615`.
+
+| # | verdict | my failure count | author's |
+|---|---|---|---|
+| MR | RED | 19 failures / 11 named | 19 / 11 ✔ |
+| MS1 | RED | 22 / 14 | 22 / 14 ✔ |
+| MS2 | RED | 19 / 11 | 19 / 11 ✔ |
+| MS4 | RED | 2 | 2 ✔ |
+| MS5 | RED | 16 | 16 ✔ |
+| MS6 | RED | 3 | 3 ✔ |
+| MS7 | RED | 2 | 2 ✔ |
+| MS8 | RED | 20 / 12 | 20 / 12 ✔ |
+| MS3 | RED | 16 / 8 | 16 / 8 ✔ |
+| MS9 | RED | 1 | 1 ✔ |
+
+(MS3 and MS9 I reconstructed myself in `rjrev_mut2.py` since they are
+`if False:` on the two prints; both red on the tests the author names.)
+
+**MS5, the one the brief singles out, is confirmed including the sibling
+claim.** Changing `REGISTER_IDENTITY["intake"]` to `lambda r: r.get("order")` —
+the row POSITION, which a swap preserves — reddens 16 tests, and two of them
+are
+
+```
+test_a_repeated_identity_is_no_identity_even_when_no_two_are_adjacent
+test_a_row_replaced_by_hand_does_not_hand_its_discharge_to_the_newcomer
+```
+
+both of which live in `tests/test_register_store_invariant.py:907` and `:944` —
+the **sibling** module, which knows nothing about this row. So
+`carry_forward_is_addressable` really does read the same map the report reads.
+That is the "one tuple, one place" claim proved by a mutation rather than
+asserted by a comment, and the claim in § 5 is accurate.
+
+---
+
+## 6. Claim 4 — every control shown able to fail. **VERIFIED, AND MORE STRONGLY THAN CLAIMED.**
+
+**The control's own control.** `test_the_control_itself_can_fail_when_no_
+substitution_is_staged` builds a `Staged` on an untouched board and asserts
+`check()` raises, matching the message. I confirmed it is itself load-bearing:
+deleting control 3 from `Staged.check()` (`rjrev_mut3.py`, `C3-DELETE`) reddens
+exactly that test and nothing else. So the control that catches a fixture where
+the dangerous edit is impossible is itself caught if it is removed.
+
+**The stronger check.** I degenerated the fixture instead of the code —
+`replace_rows` made a no-op, so no board in the module is ever edited and no
+substitution is staged anywhere (`rjrev_mut4.py`). Result: **every behavioural
+test in the module dies on the CONTROL, not on the behaviour**:
+
+```
+test_an_ordinary_write_names_every_record_it_destroys  :: AssertionError: 0 != 2 : control: 2 record identities must be about to be lost
+test_the_drift_report_may_not_fall_to_zero_unaccompanied :: AssertionError: 0 != 2 : control: 2 record identities must be about to be lost
+test_the_report_names_the_lost_records_themselves      :: AssertionError: 0 != 2 : control: 2 record identities must be about to be lost
+test_the_event_carries_the_whole_lost_record           :: AssertionError: 0 != 2 : control: 2 record identities must be about to be lost
+test_the_json_payload_carries_the_report_…             :: AssertionError: 0 != 2 : control: 2 record identities must be about to be lost
+test_the_named_way_back_is_a_subcommand_that_exists    :: AssertionError: 0 != 2 : control: 2 record identities must be about to be lost
+… (every remaining behavioural test, same message)
+test_one_of_a_duplicated_pair_deleted_by_hand_is_reported :: AssertionError: 0 != 1 : a set-subtraction answer is 0 here
+```
+
+That is the exact inverse of the parent row's defect — a test on a board where
+the dangerous edit is not possible. Here no such test exists: if the board
+stops being a substitution, the module says so in the control's own words
+before it reaches any behaviour. The "swept row IS lost by identity" control is
+separately shown live by MS1, which reddens
+`test_an_intake_sweep_removes_records_and_is_not_a_finding` on the control
+line.
+
+**Other green-for-the-wrong-reason modes, checked and absent:** no fixture
+parses zero rows (`assertGreater(len(before), 0)` is control 1, and control 3
+requires exactly `n` identities to be about to be lost, which an empty store
+cannot satisfy); no substring assertion over a whole file — the assertions are
+against the command's own captured stream and against the parsed record count;
+no test asserts only on a constant.
+
+---
+
+## 7. Claim 5 — baselines. **REPRODUCED, back to back on one machine.**
+
+Both on `git archive` extractions in scratch. Run consecutively in the same
+shell so the twenty minutes between them is the whole gap.
+
+| tree | md5 `bin/perry-task` | window | result |
+|---|---|---|---|
+| `main` @ `49d83fc` | `377dec1cfb91e44189679055af159b50` | **09:48–09:59** | **103 modules · 3098 tests · 3 red · 4 failures** |
+| tip @ `980c830` | `23e26fc319012fa1dadfe3e1ce361615` | **09:59–10:08** | **104 modules · 3123 tests · 3 red · 4 failures** |
+

+test_kr_progress_provenance  test_no_current_in_the_payload_claims_to_be_a_measurement
+```
+
+None touches a register store. The author's `103 / 3098 / 4` → `104 / 3123 / 4`
+is exactly what I measured, and the brief's warning about the count being
+data-dependent is why I ran them nine minutes apart against the same committed
+`perry/`. `python3 -m unittest test_register_substitution` on the tip: **25
+tests, OK**.
+
+---
+
+## 8. The declared gap — ruling
+
+**The literal property does not hold, and I confirm it does not.** On the tip,
+`· intake store: 42 record(s), 10 row(s) drifted` still becomes `… 0 row(s)
+drifted` across the substitution, exactly as on `main`.
+
+**I rule the close acceptable, and I would rule the opposite unacceptable.**
+
+The literal wording — "the drift report must not decrease while canonical
+records are being destroyed" — asks `perry-lint` to report a disagreement that
+no longer exists. After the write the board and the store genuinely agree; I
+measured it. A drift check that kept counting a resolved disagreement would be
+a second false claim pointed the other way, and this project has spent five
+rounds on the cost of one.
+
+The defect the row was filed for is the **silence in the middle**:
+`10 drifted → (nothing) → 0 drifted`. That is closed, and closed at the moment
+it happens rather than after the fact. The middle term is now a count that
+equals the number lost, the records themselves named, the register named, the
+heading named, a working way back named, and the whole records in the event —
+which I verified is sufficient to reconstruct the store, `discharged` included.
+
+Holding the property literally needs what the author says it needs: a durable
+"N records were destroyed and nobody has acknowledged it" surface with a
+clearing condition. That is a new state file, a new command and a decision
+about the clearing condition — a warning that can never be cleared is a warning
+everybody learns to skip, which is this same defect in a slower form. Inventing
+it inside this row is precisely the move that failed five times upstream.
+
+What matters for the verdict is that the author **recorded the gap in § 7.1 and
+did not restate the property to fit what shipped**. The restated form in § 2 is
+labelled as a restatement, sits beside the literal wording, and is falsifiable
+on its own — and it is what the property test asserts. That is an honest close.
+
+**Condition I would attach if I could attach one:** § 7.1 and § 7.2 are rows,
+not paragraphs. Neither is filed.
+
+---
+
+## 9. What I found — the one place the row's own standard is not met
+
+**A guard in this diff survives its own deletion, and it is the guard whose
+docstring names the row's own failure mode.**
+
+`SUBSTITUTION_RECORDS_SHOWN`'s comment says: *"the cap is on the OUTPUT, never
+on the count — a report that shortened its own number to fit the terminal would
+be the exact failure this row exists to close."* Nothing tests it.

++        f"⚠ {len(shown)} canonical {key} record(s) {verb} this write, and the "
+```
+
+— the report announcing 5 destroyed records when 10 died. **71 tests, OK.**
+Every test in the new module stages at most 3 losses, so the
+`SUBSTITUTION_RECORDS_SHOWN = 5` branch is never reached and the
+cap-versus-count distinction has no automated test at all. Two smaller
+survivors sit in the same untouched display path: `X-VERB` (the past tense on a
+real write, which § 2 argues is load-bearing) and `X-TAIL` (the `", and N more"`
+summary).
+
+**Why this is not a FAIL.** The shipped code is correct and I measured it
+correct in exactly the regime the tests do not reach: my own tip reproduction
+destroyed **10** records and the write printed `⚠ 10 canonical intake
+record(s)`, with `… and 5 more` after the first five identities. So the row's
+headline case exercises the >5 path and it reports the true number. The gap is
+a missing regression test, not a wrong answer, and every behavioural claim the
+row makes survives it.
+
+**What I would want in a follow-up:** one test that stages more than
+`SUBSTITUTION_RECORDS_SHOWN` losses and asserts the headline count equals the
+number destroyed while the listing is capped. It is four lines and it closes
+the only mutation in this diff that lives.
+
+---
+
+## 10. Not checked
+
+* **The full 3123-test suite per mutation.** I ran two modules (71 tests) per
+  mutation, as the author ran six (264). A mutation that reddens nothing in
+  those two but something elsewhere would look green to both of us.
+* **The author's 264-test six-module control** — I ran the 71-test two-module
+  control instead, and it was OK before every mutation.
+* **`route`.** It is in `REGISTER_EVENTS` (→ `intake`) and it is not in the new
+  module's `ORDINARY` map. I could not drive it (its flags are not the ones I
+  guessed) and did not pursue it. Whether a substitution under a `route` is
+  reported is unverified by me; the mechanism is register-wide and command-
+  agnostic, so I expect it is, but I did not see it.
+* **Crash recovery** at the `replace_canonical_pair` boundary — the report is
+  printed after the write returns, so a crash inside the rename means no report
+  and no write; reasoned from the ordering, as the author did, not probed.
+* **Concurrency** between two Perry writers.
+* **`risks.jsonl` on a localized board** end to end — I drove `zh` on `asks`,
+  as the author did.
+* **The fourth ending** was judged on the author's argument and on the code I
+  read (`intake` joins on `order`, `carry_forward_is_addressable` refuses a
+  repeated identity). I did not build it and measure its blast radius.
+* **`perry/evidence/2026-08/TASK-243-spec.md` is absent from this branch.** I
+  read it from `main` @ `f92aed1`. If the branch is expected to carry it, it
+  does not.

+
+## 0. The short version
+
+- **The call site is `tests/test_task_writer.py:1359`** (at `49d83fc`), inside
+  `TestTheCommandSurface.test_every_accepted_command_runs_and_is_advertised`,
+  which begins at line 1336. The loop is at 1357; the offending invocation is
+  the list at 1359:
+
+      ["python3", str(PERRY_HOME / "bin" / "perry-task"), name],
+
+  No `--root`. `bin/perry-task` resolves its project root from `$PERRY_PROJECT`,
+  else the cwd (`bin/perry-task:7101-7102`), and `tests/run` cds to the
+  repository root (`tests/run:23`). So all 29 names in `PT.COMMANDS` ran against
+  the **live checkout**.
+- **Twenty-eight of the twenty-nine refused for want of arguments.
+  `intake-sweep` takes none.** It discharged a real board row and moved four
+  files. Swept all 29 the same way against a scratch copy, it is the **only**
+  writer among them.
+- **Two changes.** The call site takes a throwaway `Project()` root; and
+  `tests/tree_guard.py` + a step 0 in `tests/run` fails the suite when the tree
+  it started in is not the tree it ends in, byte for byte, on every exit path.
+- **The guard was mutation-tested seven ways and the reverted fix was measured
+  against it**: with `--root` taken back off the call site and one intake row
+  discharged, the module itself is green and the suite comes back **red naming
+  exactly the four files of this row**.
+
+## 1. The call site, and how it was found
+
+Not by reading. `perry-task` was instrumented in a scratch copy to log `argv`,
+`cwd`, the process chain and a Python stack whenever the resolved
+`project_root` was the repository root, and the suite was run once.
+
+**My instrument counted 106 such invocations. Take that as my instrument's
+number, not as the population.** It logs *after* `parse()` and after the
+`COMMANDS` guard, so every argparse refusal is invisible to it; a reviewer
+instrumenting at process start got **88 un-rooted + 22 explicitly repo-rooted =
+110**. The two counts are measuring different sets and neither is wrong. What
+both measured, and what the claim rests on, is the shape: many un-rooted
+invocations, **one writer among them**. Nothing below depends on 106.
+
+The chain, from `bash tests/run` → `tests/parallel` →
+`python3 -m unittest discover -s tests -p test_task_writer.py -v` →
+`bin/perry-task <name>`. Most are reads (`list --json`, `events --json`).
+The write is one line:
+
+    tests/test_task_writer.py:1357   for name in PT.COMMANDS:
+    tests/test_task_writer.py:1359       ["python3", str(PERRY_HOME / "bin" / "perry-task"), name],
+
+`intake-sweep` is dispatched with no arguments, finds the discharged rows in
+`## Intake`, pops them off the board, writes the intake store, appends a
+journal block and an `intake-sweep` event with `actor: agent`
+(`bin/perry-task § cmd_intake_sweep`, 5206).
+
+**Why nobody found it by reading**: the test's stated purpose is *"a name a
+user can type is a name that runs"*, and reaching it through the CLI rather
+than the dispatch dict is deliberate and correct. What it forgot is that a
+command that runs, runs somewhere.
+
+## 2. The four files, before and after
+
+A scratch copy of this worktree, one intake row discharged first so the sweep
+had something to find (an already-swept tree moves nothing — that is the whole
+reason this survived), then **one test**, run alone:
+
+    python3 -m unittest discover -s tests -p test_task_writer.py \
+            -k test_every_accepted_command_runs_and_is_advertised
+
+| file | before | after |
+|---|---|---|
+| `.perry/events.jsonl` | `51be520c47a76fe5d5ca093ec381c2da` | `b212ee31121034155be8366c4ee655c7` |
+| `perry/BOARD.md` | `468f847c1dd5ee55099ba538768854f7` | `6352b6307bbd4a53c1b08b9c0a585736` |
+| `perry/intake.jsonl` | `642fe5913e123a85f647a0eeeb0ddb3c` | `53bccb3a74b372b99eacff209be062f4` |
+| `perry/journal/2026-08/2026-08-30.md` | `de086b6727b34724bbb3ac2a042d0ad4` | `2ffe91b21fd5d2ed2261c6faa7e09349` |
+
+The event that landed, verbatim:
+
+    {"ts": "2026-08-30T08:59:58+08:00", "event": "intake-sweep", "id": "",
+     "title": "", "count": 1, "actor": "agent", "from": "intake",
+     "to": "journal"}
+
+That is the same shape as the stray event the PMO caught in TASK-241's merge.
+
+**After the fix**, same scratch copy, same discharged row present, same single
+test: all four md5s **unchanged**. And with the whole `test_task_writer`
+module run through `bash tests/run --only test_task_writer` against a tree with
+a discharged row, all four unchanged and the guard green (§ 4, control).
+
+**Which commands write.** All 29 of `PT.COMMANDS`, invoked bare against a
+scratch copy with one row discharged, hashing the whole tree after each:
+
+    WRITER intake-sweep rc=0  ['.perry/events.jsonl', 'perry/BOARD.md',
+                               'perry/intake.jsonl',
+                               'perry/journal/2026-08/2026-08-30.md']
+
+One writer, four files, and the same four. Repeating the sweep immediately
+afterwards reports **no writer at all** — the idempotence, measured.
+
+## 3. Which mechanism, and why
+
+The spec offered two shapes. **I took the tree-unchanged guard**, and fixed the
+call site as well.
+
+**Why not only a fixture that refuses a root inside the repository.** A fixture
+guard could not have caught this one. The offending call site does not go
+through a fixture — it builds its own `argv` and calls `subprocess.run`
+directly, which is *why* it got the root wrong. Every call site that already
+uses `Project()` is already correct; a fixture guard would protect exactly the
+callers that never needed protecting. The guard has to sit where it does not
+care how the write arrived: fixture, bare subprocess, a stray `open(..., "w")`,
+or a tool three layers down that resolved a root from the cwd.
+
+**What was built.**
+
+- `tests/tree_guard.py` — `manifest(root)` maps every path to a token that
+  changes when it does (files hash their bytes; symlinks record their target
+  without following it; directories are recorded so an empty one created
+  counts). `compare(before, after)` reports `+ / - / M` lines. A CLI with two
+  verbs, `snapshot` and `verify`; `verify` exits 1 and names every path.
+- `tests/run` step 0 — snapshot before step 1, verify from an **EXIT trap**.
+  The trap is not decoration: `--lint` exits early at line 82 and any `set -e`
+  abort exits earlier still, and a guard with an exit path around it reports
+  only on the runs that were fine. The trap also owns the final banner, because
+  a `✓ all green` printed before the guard has spoken is a lie half the time.
+- The manifest is written **outside** `$ROOT` (`mktemp`), since a manifest
+  written into the tree it describes is itself a change to that tree.
+
+Cost: 0.4s to hash this repository, twice per run. `bash tests/run --lint` is
+0.57s end to end with the guard in it.
+
+**`tests/run --only PREFIX`** was added alongside: it narrows step 2 to modules
+matching the prefix and skips steps 3 and 4, saying so on stdout. The guard's
+own test has to drive the **real** runner around a planted write, three times,
+and a full run is 150-310s.
+
+## 4. The guard's own test, and its mutation
+
+`tests/test_tree_guard.py`, 13 tests, 5.1s on a quiet machine.
+
+The load-bearing one is `TestThePlantedWrite`. It copies this repository to a
+scratch dir, writes a module into the copy's `tests/` that appends to the
+copy's own `perry/BOARD.md` and creates `.perry/task-249-planted.txt`, and runs
+the real `bash tests/run --only ...` there. Required: the suite is **red** and
+names both paths — `M perry/BOARD.md` and `+ .perry/task-249-planted.txt` — and
+the planted module itself is **green**, so the red is the tree and not the test.
+
+Its two companions exist because a red that would have been red anyway proves
+nothing:
+
+- `test_the_same_run_is_green_when_the_guard_is_neutered` — the **mutation,
+  in-suite**. It resolves the anchor `lines = compare(before, manifest(root))`
+  in the copy at run time, **asserts it is unique**, replaces it with
+  `lines = []`, runs the identical plant, and requires **green** — then reads
+  the copy's `perry/BOARD.md` back to confirm the write really fired.
+- `test_a_module_that_stays_in_a_temp_root_is_green` — the control. Same
+  runner, same `--only` path, a module that writes only into a temp dir. Green.
+  Without it, a red plant could mean "the guard works" or "`--only` is broken".
+
+**The harness.** `task249_tree_guard_mutation_harness.py` (scratch, not
+committed — it is a one-off and this repository does not need a fifth one).
+It refuses a dirty tree, asserts `test_tree_guard.py` is GREEN before touching
+anything, resolves each anchor at run time and asserts it is unique, clears
+`__pycache__` before and after, sleeps 1.1s past the whole-second boundary so
+no mtime-keyed `.pyc` can be served stale, and restores from the saved bytes
+verified by **md5**.
+
+    baseline: test_tree_guard.py GREEN — Ran 17 tests
+
+    ✓ M1  tree_guard.compare is never consulted               RED (3 tests)
+    ✓ M2  verify never runs (the trap calls true)             RED (1)
+    ✓ M3  the EXIT trap is not installed                      RED (3)
+    ✓ M4  a moved tree exits 0 instead of 1                   RED (2)
+    ✓ M5  file contents are recorded without their hash       RED (4)
+    ✓ M6  a created path is reported as changed               RED (3)
+    ✓ M7  the snapshot is taken after the suite, not before   RED (3)
+    ✓ M8  IGNORE_NAMES blinded to two of the four files       RED (2)
+    ✓ M9  IGNORE_DIRS blinded to the state directory          RED (3)
+    ✓ M10 IGNORE_SUFFIXES blinded to the stores               RED (3)
+    ✓ M11 the PERRY_PROJECT refusal is removed                RED (1)
+    ✓ M12 the file token drops the permission bits            RED (1)
+
+    restored: test_tree_guard.py GREEN
+    12/12 mutations red
+
+M8 through M12 are the V4 corrections, and **M8 is the one that had to be
+added rather than found**: setting `IGNORE_NAMES = {".DS_Store",
+"events.jsonl", "intake.jsonl"}` — blinding the guard to two of this row's own
+four files — left all thirteen of the first version's tests green. See § 7.
+
+**M8 — the one that matters, and it is not in the suite.** Would this guard
+have caught TASK-249 itself? Measured on a scratch copy with one intake row
+discharged and the `--root` taken back off the call site, running the real
+`bash tests/run --only test_task_writer`:
+
+    ✓ all green                     ← tests/parallel: the module passed
+
+    0. tree guard — the tree the suite started in is the tree it ends in

+      M perry/BOARD.md   (changed)
+      M perry/intake.jsonl   (changed)

+
+    ✗ failures above                rc=1
+
+Exactly the four files of this row, from a module that was green. The control
+— same copy, same discharged row, fix restored — is `rc=0`, `✓ nothing moved`,
+and all four md5s identical before and after.
+
+**Re-run after § 6's corrections** (`42e8213`, with the shrunken `IGNORE_DIRS`,
+the mode in the token and the `PERRY_PROJECT` refusal in front of it): same
+result, `rc=1`, module `✓ all green`, guard red naming the same four `M` lines.
+
+## 5. Baselines — **and a retraction**
+
+### 5.1 The retraction
+
+**An earlier version of this section reported the fork point at 3 failures and
+concluded that the PMO's 4 "measured a working tree with uncommitted board
+edits — which is this row's own point." Both halves are withdrawn. The PMO's
+number was right, my correction was wrong, and the accusation resting on it was
+unfounded.**
+
+The fork point, `git archive 49d83fc` into a scratch directory, is **4 failing
+tests in 3 red modules**, deterministically, on the committed tree. `test_diagnose`
+fails **twice**:
+
+    ✗ test_diagnose.py               FAILED (failures=2)
+        test_the_queue_register_reconciles_with_the_queue_on_this_repository
+            AssertionError: 3 != 1 : diagnose and perry-task disagree about
+            how many queue rows are waiting on the user
+        test_perry_itself_passes_its_own_id_checks
+    ✗ test_heading_title.py          FAILED (failures=1)
+    ✗ test_kr_progress_provenance.py FAILED (failures=1)
+
+The one my list dropped — `test_the_queue_register_reconciles_with_the_queue_on_this_repository`
+— is **one of the two board-data-dependent tests this row exists to protect**.
+Of all the failures to lose, it was that one.
+
+This is also already written down: the project's filed intake row of
+2026-08-29 says the `tests/run` baseline is *"4 failures on a clean archive
+copy"*. I did not check the filed number against mine. Had I done so, one line
+of arithmetic would have stopped this.
+
+### 5.2 What actually happened — three numbers that all look like a count
+
+Deleting the wrong number is not enough, because the trap is still there and it
+is now filed as **TASK-251**. `tests/run` offers three readings and two of them
+say 3:
+
+| reading | gives | why |
+|---|---|---|
+| `grep -cE '^FAIL:'` | **3** | what I used |
+| sum of `FAILED (failures=N)` | **4** | correct |
+| `✗ N module(s) red` | **3** | modules, not tests — and it is the line the runner prints last |
+
+The mechanism is `tests/parallel:283`:
+
+    print("\n".join(r["err"].strip().splitlines()[-25:]))
+
+A red module's stderr is **truncated to its last 25 lines**. `test_diagnose`
+fails twice; the second failure's `FAIL:` header survives inside that window and
+**the first one's does not**, so the first failure reaches the log as a bare
+traceback with no `FAIL:` prefix. My grep counted headers. There is no warning,
+nothing is elided visibly, and the surviving output looks complete.
+
+I am the third agent caught by this in twelve hours, and one of the others had
+documented the trap in its own result before walking into it. So, stated as a
+rule rather than as an apology: **on this suite the failure count is the sum of
+the `FAILED (failures=N)` lines, or the module re-run alone. Never a grep for
+`FAIL:`, and never the module-red count.** I have not touched `tests/parallel`
+— TASK-251 is its own row and it is the PMO's to schedule.
+
+### 5.3 The numbers, counted correctly
+
+Runner `bash tests/run` (module-parallel, 8 workers), 2026-08-30, on a machine
+also running other agents' suites — wall times are recorded but not comparable.
+
+| tree | when | modules | tests | failures |
+|---|---|---|---|---|
+| `49d83fc`, per the PMO | 08:48 | 103 | 3098 | **4** |
+| `49d83fc`, `git archive`d to a scratch dir, re-run here | 09:21-09:26 | 103 | 3098 | **4** |
+| this branch at `fbab26a` | 09:16-09:21 | 104 | 3111 | **4** |
+| this branch at `42e8213`, after the V4 corrections | 10:31-10:39 | 104 | 3115 | **4** |
+
+**The fork point and the branch agree at 4, and the PMO's figure is reproduced
+exactly.** `+1 module / +17 tests` is `tests/test_tree_guard.py` (13 tests at
+`fbab26a`, 17 after § 6's corrections). The same four failures by name on both
+trees, none of them in a file this branch changes:
+
+- `test_diagnose § test_the_queue_register_reconciles_with_the_queue_on_this_repository`
+- `test_diagnose § test_perry_itself_passes_its_own_id_checks`
+- `test_heading_title § test_none_of_them_contains_its_own_id` — the filed one,
+  fires on a legitimate multi-row evidence document. Not touched.
+- `test_kr_progress_provenance § test_no_current_in_the_payload_claims_to_be_a_measurement`
+
+**A flake, recorded rather than filed — the board is the PMO's.** A later run
+added a fifth, `test_host_support §
+TestOpenCodeDispatchLimit.test_concurrent_mixed_registers_do_not_exceed_global_cap`.
+Re-run alone on this branch three times: **green, green, red**; once at the fork
+point: green. A concurrency test about a global dispatch cap, on a machine
+running several suites at once, in a module this branch does not touch. Four
+re-runs, not forty.
+
+**The tree guard is green on both full runs of this branch**, the working tree
+is clean afterwards, and the four files are byte-identical before and after:
+
+    19370b5e4817143e6bcf4a8bf564cdb9  .perry/events.jsonl
+    084728c777af398acda59fc48dc3e843  perry/BOARD.md
+    b73d602268fabb1b647265518de117a0  perry/intake.jsonl
+    b9a6eaed43359fe26ffad193ee6f709c  perry/journal/2026-08/2026-08-30.md
+
+## 6. What a V4 round defeated, and what changed
+
+The round could not break the core — the call site, the plant, M8, the trap,
+the control — and got past the guard's *edges* three times. All three are
+closed and each is now mutation-covered. They are recorded because the pattern
+matters more than the fixes: **every one of them was a place where the guard
+was pinned by NAME and could be defeated by CONSEQUENCE.**
+
+1. **Two of three ignore lists were pinned.** `IGNORE_NAMES = {".DS_Store",
+   "events.jsonl", "intake.jsonl"}` blinds the guard to two of this row's own
+   four files and left all 13 tests green. Now all three are pinned by
+   equality, *and* `test_the_four_files_of_this_row_are_never_invisible` pins
+   the property by consequence — it plants a change in each of the four files
+   and requires all four to be reported — so a fourth list invented tomorrow is
+   caught without anyone remembering to pin it. M8/M9/M10.
+
+   `IGNORE_DIRS` also **shrank**, six names to two. `.pytest_cache`,
+   `.mypy_cache`, `.ruff_cache` and `node_modules` were carried here from
+   habit; this repository contains none of them and no tool that makes one
+   (checked: zero hits each). An ignore entry that matches nothing is a blind
+   spot held open for no benefit.
+
+   **Round 2 was right that this reasoning contradicted the `.git` bullet nine
+   lines above it, and § 8.4 replaces both with one rule.** Under that rule the
+   deletion stands and `.claude` and `.gstack` join the list; `IGNORE_DIRS` is
+   four names now, and the equality pin moved with it in the same commit.
+
+2. **File mode was not recorded.** `chmod +x` on a shipped script changes what
+   the tree is without changing a byte of it, and this repository ships
+   executables whose bit is load-bearing. The token now carries the permission
+   bits, for files and directories. M12.
+
+3. **`$PERRY_PROJECT` aimed at a second checkout — live on this machine.**
+   `perry-task` resolves its root from `$PERRY_PROJECT` *before* the cwd, so a
+   suite run in a worktree by an agent that has it exported at the main
+   checkout moves all four files **over there** while step 0 truthfully reports
+   this tree unmoved. The reviewer demonstrated exactly that. `tests/run` now
+   **refuses to start** in that environment, before step 1.
+
+   It does not silently re-point the variable. `export PERRY_PROJECT="$ROOT"`
+   was tried first and reddens **nine** tests in `test_config_store_readers`
+   that need it absent so the cwd walk runs — a guard that has to bend the
+   suite to fit is a guard that will be bent back. Refusing costs nothing:
+   afterwards the only reachable states are unset (→ cwd → `$ROOT`, which
+   `cd "$ROOT"` just set) and equal to `$ROOT`, and both land inside the tree
+   step 0 hashes. A companion test asserts `PERRY_PROJECT == $ROOT` is still
+   **allowed**, so the refusal cannot be satisfied by refusing everything.
+   M11.
+
+   **Two things about this were wrong and § 8 fixes them.** The comparison was
+   raw-string against `pwd -P` while `perry-task` `.resolve()`s, so three
+   spellings of *this very tree* were refused (§ 8.3); and the module docstring
+   went on describing the re-aim — the approach withdrawn in the paragraph
+   above — as the thing that shipped (§ 8.1).
+
+**And one thing the project had already written down.**
+`tests/live_state_expectations.py § _tool_reads_this_project` decides which
+project a test's tool call reads from `--root`, then `cwd=`, then a state path,
+and says of a call carrying none of the three:
+
+> "With none of them the answer is no — the tool would in fact inherit the
+> runner's cwd and so read this repository, but `--help` and `--version` runs
+> are the bulk of that population and **none of them touches state**. A stated
+> blind spot, not a claim."
+
+TASK-249's call site is exactly that shape and `intake-sweep` is the
+counterexample to the last sentence. The blind spot was declared honestly and
+the population turned out to have a member that wrote. That is the argument for
+watching the tree instead of reading the call: a static guard can only ever be
+as good as its claim about what the part it cannot analyse contains. I have not
+changed that file — it guards expectations, not writes, and its statement is
+now falsified in a way its owner should decide about.
+
+## 7. What I could not close
+
+Ordered by how likely each is to matter.
+
+1. **The guard cannot see an idempotent write on an already-written tree.**
+   The sweep that motivated this row moves nothing on a tree it has already
+   swept, so on `main` today the guard is green either way. It catches the
+   **first** occurrence — which is the one that would have been caught in the
+   first place, and the one that matters — not the steady state. Stated in
+   `tests/tree_guard.py`'s docstring, not left for the next reader to find.
+2. **A test that builds its own `env=` dict naming a third directory.** § 6's
+   refusal closes the *ambient* `$PERRY_PROJECT` case, which is the one that is
+   live on this machine. It does not reach a test that constructs an
+   environment for its own subprocess. No comparison of one tree against
+   itself can, and I have not invented a mechanism that would; it is declared
+   in the module docstring and here, and nowhere else did I claim coverage.
+3. **The call-site fix has no test of its own on this tree.** Its test is the
+   guard, and the guard only reddens where the sweep has a row to find. § 4's
+   M8 is that test, and it is a scratch-copy measurement, not a suite test.
+   Making it a suite test means running the longest module in the suite
+   (`test_task_writer`, ~95s) inside another test, against a copy seeded with a
+   discharged row. Too expensive to add; recorded rather than pretended.
+4. **`.git` is ignored**, so a test that runs `git commit` in the live root
+   gets through. Hashing `.git` against a live repository is slow and noisy —
+   index and ref mtimes move under any concurrent git command, including a
+   reviewer's `git log` in another terminal, and a guard that is red for
+   reasons the reader did not cause is a guard that gets switched off.
+5. **`__pycache__`, `*.pyc` / `*.pyo`, `.DS_Store`, `.claude` and `.gstack`
+   are ignored at any depth.** Deliberate and unbounded: bytecode legitimately
+   appears beside any Python file, the Finder writes `.DS_Store` into whatever
+   directory a human opened, and `.claude`/`.gstack` belong to the agent
+   harness rather than to the suite (§ 8.4). The `.claude` hole is the widest
+   of the five — a test writing `.claude/settings.local.json` would go unseen —
+   and it is taken knowingly, because the harness creates that directory from
+   outside the run. All three lists are pinned twice, by name and by
+   consequence.
+6. **A write that is reverted before the suite ends is two writes and one
+   tree.** The guard compares ends, not the path between them.
+7. **The un-rooted `perry-task` invocations that only READ are left alone.**
+   `list --json`, `events --json` and friends against the live checkout are
+   harmless, and several are reading this repository's own board on purpose.
+   Rooting them all is a separate row.
+8. **`tests/merge-check` has no guard.** It calls `tests/parallel` and the two
+   `bin/perry-lint` gates directly, not `tests/run`, so step 0 does not cover
+   it. It merges into a throwaway `git clone --shared` under a temp dir and
+   runs there, so an un-rooted write during a merge-check lands in the clone
+   rather than in anybody's checkout — which is why this is a note and not a
+   second guard. If that isolation ever changes, this becomes a hole.
+9. **`tests/parallel`'s 25-line truncation is untouched.** It is the mechanism
+   behind § 5.2 and it is filed as TASK-251. Fixing the runner that reports
+   failures, from inside a row about the suite corrupting its own state, is
+   the PMO's call and not mine to take mid-round.
+10. **`tests/live_state_expectations.py`'s stated blind spot is now falsified**
+    (§ 6) and I did not change it. It guards expectations, not writes; whether
+    its sentence should be rewritten or its rule widened is a decision about
+    that guard, not about this one.
+11. **I did not touch `perry/BOARD.md` or `perry/tasks.jsonl`.** The PMO owns
+    them. The flake in § 5.3 and the falsified sentence in § 6 are reported
+    here rather than filed for the same reason.
+
+## 8. Round 2 V4 — PASS, three defects, and two decisions asked for
+
+Round 2 (`perry/evidence/2026-08/TASK-249-round2-v4-review.md`) PASSed the row,
+re-derived twelve mutations of its own at 12/12 red, and blocked the merge on
+one documentation defect. It named three more things to fix or file, and two
+to decide either way. All of them are closed here; nothing is deferred.
+
+**Everything below was measured on this machine in this session.** Where round
+2 quotes a figure I re-ran it rather than repeating it, and where my number
+differs from a number I was handed, mine is the one in the table with the
+instrument beside it.
+
+### 8.1 Defect 1 — a withdrawn approach described as shipped (the blocker)
+
+`tests/tree_guard.py:60-67` said, inside **"What it does NOT catch, said
+plainly"**:
+
+> **`tests/run` closes the ambient case** by exporting `PERRY_PROJECT="$ROOT"`
+> for the whole run, which pins every un-rooted write into the tree the guard
+> is watching rather than letting it escape to a neighbour.
+
+`tests/run` does not do that. It refuses — as `tests/run:52-58` and
+`tests/test_tree_guard.py:136-139` both say, and as § 6 item 3 above says. The
+export was tried and rejected. So the file's one list whose entire job is to
+tell the next reader what is *uncovered* told them a mechanism was in place
+that was not, and named a mechanism with different properties from the one
+that shipped: a reader who believed it would conclude that a foreign
+`$PERRY_PROJECT` is silently re-aimed and safe, when the suite in fact stops
+dead at rc=2.
+
+The bullet now describes the refusal. A new section, *Why a refusal and not a
+re-aim*, carries the reason the other approach lost — **re-measured, not
+quoted**, on a `tar` copy of this branch:
+
+    $ env -u PERRY_PROJECT python3 -m unittest discover \
+          -s tests -p test_config_store_readers.py
+      Ran 44 tests in 1.077s
+      OK
+
+    $ PERRY_PROJECT="$COPY" python3 -m unittest discover \
+          -s tests -p test_config_store_readers.py
+      Ran 44 tests in 1.519s
+      FAILED (failures=7, errors=2)
+
+**Nine**, and the figure § 6 carried is confirmed — as 7 failures plus 2
+errors, which is worth saying, because `grep -c '^FAIL:'` on that output
+returns 7. The exported run also wrote `.perry/config.md` into the copy on its
+way past, which is the mechanism in miniature.
+
+**And it is pinned, narrowly.** "The docstring matches the code" is not
+mechanically checkable, and a test claiming to check it would be the
+decoration this row keeps finding. The pin class — named
+`TestTheDocstringSaysWhichMechanismShipped` here, renamed
+`TestTheBulletUsesTheVocabularyOfTheMechanismSpelledInTestsRun` in § 9.2 when
+round 3 showed the old name claimed more than the test reads —
+checks exactly one proposition instead: closing the ambient case has two
+mutually exclusive implementations — RE-AIM (`export PERRY_PROJECT="$ROOT"` on
+a non-comment line) and REFUSE (the `refusing to run: PERRY_PROJECT` banner) —
+so read which one `tests/run` contains, require **exactly one**, and require
+the `- **A write to a DIFFERENT checkout.**` bullet to use that mechanism's
+word and not the other's. Two tests, three mutations, all red (§ 8.5).
+
+Its own docstring says what it does not check: every other sentence in either
+file, and whether the description is any good. It catches one class of rot —
+the two files disagreeing about which of two named mechanisms is in the tree —
+and it catches it in both directions.
+
+### 8.2 Defect 2 — "eleven executables", declared and wrong, twice
+
+`tests/tree_guard.py:129` and `tests/test_tree_guard.py:348` both said this
+repository ships **eleven** executables whose bit is load-bearing. Measured:
+
+    $ git ls-tree -r HEAD | awk '$1=="100755"' | wc -l
+    24
+    $ git ls-tree -r HEAD | awk '$1=="100755" {print $4}' | grep -c '^bin/'
+    18
+    $ find . -type f -perm -u+x -not -path './.git/*' | wc -l
+    24
+
+18 under `bin/`, plus `setup`, `templates/knowledge-base/bin/kb-lint`,
+`templates/ops/bin/deliverable-lint`, and `tests/merge-check`, `tests/parallel`
+and `tests/run`. No grouping gives eleven; the number was invented.
+
+**Changing 11 to 24 would be the same defect one value later**, so the number
+is gone from both places. `manifest`'s docstring describes the set instead and
+says out loud why there is no count in it.
+`test_the_executables_this_repository_ships_carry_their_mode` **derives** it:
+it takes the executables straight out of the manifest of this repository,
+cross-checks each one against `os.access(X_OK)` so the test is not reading its
+own answer back, requires every shipped `bin/perry-*` to be in the set, and
+names all six outside `bin/` that the docstring describes. The size is
+whatever it is on the day.
+
+### 8.3 Defect 3 — the refusal compared raw strings; `perry-task` resolves
+
+`tests/run:30` computes `ROOT` with `pwd -P` and the guard compared
+`"$PERRY_PROJECT" != "$ROOT"` as raw text, while `bin/perry-task` does
+`Path(os.environ.get("PERRY_PROJECT") or Path.cwd()).resolve()`. Reproduced at
+`8dfd25e` on a copy, `bash tests/run --lint` under each spelling:
+
+| `PERRY_PROJECT` | at `8dfd25e` | now |
+|---|---|---|
+| `$ROOT` (already `pwd -P`) | accepted | accepted |
+| `$ROOT/` — one trailing slash | **REFUSED** | accepted |
+| a `/tmp` symlink alias of `$ROOT` | **REFUSED** | accepted |
+| `$ROOT` spelled through `/tmp` → `/private/tmp` | **REFUSED** | accepted |
+| a genuinely foreign directory | refused | refused |
+| a foreign directory through a symlink | — | refused |
+| a path that does not exist | refused | refused, and says so |
+
+Every refused row in the middle three names *this very tree*: `perry-task`
+would resolve it to `$ROOT` and every un-rooted write would land inside the
+tree step 0 hashes. A false refusal, in a guard whose argument for refusing is
+that refusing costs nothing. On this machine, where worktrees live under
+`/private/tmp` and `/tmp` is a symlink to it, the `/tmp` spelling is the
+ordinary one.
+
+`tests/run` now resolves before comparing — `cd … && pwd -P`, the shell
+spelling of `.resolve()` — and prints the resolved value when it differs from
+the raw one. A value naming nothing resolves to the empty string and is still
+refused, correctly, because `perry-task` would go on to create it.
+
+**The test was the worse half of this.** `test_perry_project_equal_to_the_root_
+is_allowed` passed `str(root.resolve())` — the one spelling that cannot trip a
+raw comparison. A test constructed so that it cannot observe the bug it exists
+to catch is not a weak test, it is a different kind of thing. It is kept as the
+plain case, and `test_other_spellings_of_this_root_are_this_root` now runs the
+real `bash tests/run` under six spellings in subTests: symlink alias, trailing
+slash and unresolved root asserted **accepted**; foreign root, foreign root
+through a symlink, and non-existent root asserted **refused** — because
+"accept everything" is exactly how a resolution fix goes wrong.
+
+### 8.4 The two decisions round 2 asked for, recorded
+
+**(a) `.claude/` and `.gstack/` — DECIDED: both ignored.** Both exist in the
+live checkout, both are gitignored, both are written by tooling rather than by
+tests, and neither has a single tracked file (`git ls-files .claude` and
+`git ls-files .gstack` are empty). `.gitignore` describes `.claude/worktrees/`
+verbatim as "Subagent worktrees — temporary, created by the Agent tool", and
+on this machine a subagent starting during a five-minute run creates one from
+*outside* the suite. They join `IGNORE_DIRS`, and the equality pin moved with
+them in the same commit — which is the pin doing its job: it makes the
+addition a deliberate edit with a reason above it rather than a red quietly
+made green.
+
+Ignored **whole** rather than by inner path, because the harness creates
+`.claude` itself: ignoring only `.claude/worktrees` would still leave
+`+ .claude   (created)` red in a worktree that had none. That is a real hole
+and it is the widest of the five — a test writing `.claude/settings.local.json`
+would go unseen — and it is taken knowingly and written into § 7 item 5.
+
+**(b) The `IGNORE_DIRS` deletion versus the `.git` rationale — DECIDED: the
+deletion stands, and the two rationales are replaced by one rule.** Round 2 was
+right that they contradicted each other. The old text justified `.git` with
+*"a guard that is red for reasons the reader did not cause is a guard that gets
+switched off"* and the four cache deletions with *"an entry that matches
+nothing is a blind spot held open for no benefit"* — and taken alone the second
+deletes `.git` the day `.git` stops churning, while the first re-adds
+`.ruff_cache` on the strength of a `ruff` nobody here runs.
+
+The rule that produces every answer, and the one the docstring now states
+once: **this checkout actually produces it while a run is in flight, and no
+test may legitimately write it.** Both halves.
+
+| candidate | produced here? | no test writes it? | verdict |
+|---|---|---|---|
+| `.git` | yes — any concurrent `git log` | yes | ignored |
+| `__pycache__`, `*.pyc`/`*.pyo` | yes — running the suite compiles it | yes | ignored |
+| `.DS_Store` | yes — the Finder | yes | ignored |
+| `.claude`, `.gstack` | yes — the agent harness, mid-run | yes | ignored |
+| `.pytest_cache`, `.mypy_cache`, `.ruff_cache`, `node_modules` | **no** — no tool here makes one | yes | **not ignored** |
+
+The "no" in that table is checked, not assumed: zero hits in `git ls-files`, no
+`package.json` / `pyproject.toml` / `requirements*.txt` / `tox.ini`, nothing on
+disk, `.github/workflows/ci.yml` installs nothing, and `.vscode/settings.json`
+sets `python.languageServer` to `None`. Round 2 re-derived the same and agreed.
+
+I record the disagreement rather than hide it: round 2 said it *would* restore
+the four names, on the ground that an entry for a directory no test may
+legitimately write is a scope declaration rather than a blind spot. That is a
+fair reading, and the deliberate reason it is not taken is that the second half
+of the rule is satisfied by nearly anything — it does not by itself bound the
+list — so the first half has to do the bounding, and "a tool that does not
+exist in this repository might appear" does not bound it either.
+
+### 8.5 Mutations — nine, each anchored, each red
+
+On a `tar` copy of the tip (`.git`, `__pycache__`, `*.pyc` excluded), never on
+the live tree. Discipline, and every step of it enforced by the harness rather
+than remembered: refuse to start on a dirty tree; assert the baseline **GREEN**
+(21 tests, rc=0) before the first mutation; assert every anchor **present and
+unique** before replacing it; clear `__pycache__` and sleep past the
+whole-second boundary before every run (CPython validates bytecode on
+mtime-in-whole-seconds plus size, so a same-second edit can be run from stale
+`.pyc`); restore from the captured original bytes and assert **md5 equality**
+against the pre-mutation baseline after each one; re-assert GREEN at the end.
+
+Runner: `python3 -m unittest discover -s tests -p test_tree_guard.py -v` in the
+copy, with `PERRY_PROJECT` popped. Deliberately **not** through `tests/run
+--only`: `tests/parallel:283` truncates a red module's stderr to its last 25
+lines with nothing visibly elided, which eats `FAIL:` headers — the same trap
+that produces § 5.2's three different numbers, in a smaller room.
+
+| # | mutation | verdict | test(s) that died |
+|---|---|---|---|
+| MD-1 | the bullet reverted to the withdrawn "closes the ambient case by exporting" claim | RED | `test_the_bullet_names_the_mechanism_that_shipped` |
+| MD-2 | `tests/run` gains a real `export PERRY_PROJECT="$ROOT"` *as well as* the refusal | RED | `test_tests_run_implements_exactly_one_of_the_two_mechanisms`, `test_the_bullet_names_the_mechanism_that_shipped` |
+| MD-3 | `tests/run` implements neither (refusal banner renamed to "declining to start") | RED | the two above + `test_a_foreign_perry_project_refuses_the_run`, `test_other_spellings_of_this_root_are_this_root` |
+| ME-1 | a shipped `bin/perry-*` loses its executable bit | RED | `test_the_executables_this_repository_ships_carry_their_mode` |
+| ME-2 | `manifest` stops reporting the real mode (`0o644` hardcoded into the token) | RED | that one + `test_a_permission_change_is_a_change` |
+| MR-1 | the comparison reverted to raw strings against `pwd -P` | RED | `test_other_spellings_of_this_root_are_this_root` |
+| MR-2 | the refusal never fires — resolution taken all the way to accept-everything | RED | `test_a_foreign_perry_project_refuses_the_run`, `test_other_spellings_of_this_root_are_this_root` |
+| MR-3 | **half a fix**: trailing slash stripped (`${PERRY_PROJECT%/}`), symlinks not resolved | RED | `test_other_spellings_of_this_root_are_this_root` |
+| MI-1 | `.claude` quietly dropped from `IGNORE_DIRS` | RED | `test_all_three_ignore_lists_are_the_documented_ones` |
+
+**9/9 red, no survivors**, baseline GREEN before and after, every restore
+md5-verified. Run twice: once on the fix commit and once on the final tree, the
+same nine, the same nine verdicts.
+
+Four of these are worth more than the count.
+
+- **MD-1 kills exactly one test, and it is the new one.** The pin is specific
+  to the defect and not a by-product of something else being red.
+- **MD-2 is the direction nobody tests.** It leaves the shipped refusal intact
+  and *adds* the withdrawn mechanism — the shape a "belt and braces" edit
+  would take — and the exactly-one assertion is what catches it.
+- **MR-3 is the plausible wrong fix, not a strawman.** Stripping the trailing
+  slash is what someone reaching for the smallest change would write; it fixes
+  one of the three refused spellings and leaves the symlink alias refused. Only
+  the new test dies. The old `root.resolve()` test is green under it, which is
+  the whole finding restated as a measurement.
+- **ME-1 does not touch a line of Python.** It `chmod -x`es a shipped script,
+  which is precisely the tree change `manifest`'s mode token exists to see, and
+  it is caught by the test that replaced the invented count.
+
+**And one measurement of the ignore decision, rather than an argument for it.**
+`compare()` over a tree where a subagent worktree, a `.gstack/` and a
+`.ruff_cache/` all appear between snapshot and verify:
+
+      + .ruff_cache   (created)
+      + .ruff_cache/0.4.2   (created)
+
+`.claude/worktrees/agent-1/f` and `.gstack` are invisible — including
+`+ .claude` itself, because `os.walk`'s `dirnames` are filtered before the
+directory entries are recorded, so ignoring the parent really does ignore the
+whole subtree. `.ruff_cache` still reddens the run. That is the trade in § 8.4
+made visible: the noise this checkout produces is gone, the noise it does not
+produce is still reported.
+
+### 8.6 Baselines — measured here, in this session, on this machine
+
+Machine shared with other agents' runs; wall times recorded, not comparable.
+`bash tests/run` from each worktree root with `PERRY_PROJECT` unset, bracketed
+by `git ls-files -z | xargs -0 md5 -q | md5 -q`.
+
+| tree | modules | tests | seconds | **failures** | red modules | tree guard | tracked md5 |
+|---|---|---|---|---|---|---|---|
+| `main` @ `1274587`, fresh worktree, first run | 104 | 3124 | 260.8 | **4** | 3 | n/a (no guard on `main`) | `63dd005e…` → `63dd005e…` |
+| this branch @ `21ef128` | 104 | 3119 | 257.5 | **4** | 3 | `✓ nothing under … moved` | `d30db46a…` → `d30db46a…` |
+| this branch @ `148c7da` | 104 | 3119 | 265.0 | **4** | 3 | `✓ nothing under … moved` | `db0b48fc…` → `db0b48fc…` |
+| merge probe `7ef27db` + `21ef128` = `f069a51` | 105 | 3145 | 237.4 | **4** | 3 | `✓ nothing under … moved` | `8444ab7c…` → `8444ab7c…` |
+| merge probe `7ef27db` + `148c7da` = `67a6f80` | 105 | 3145 | 271.8 | **4** | 3 | `✓ nothing under … moved` | `6d20f385…` → `6d20f385…` |
+
+`git status --porcelain` was empty at both ends of all five.
+
+The branch and the merge were each run twice because this document grew
+between them, and two of the four failures scan evidence documents
+(`test_heading_title` and `test_diagnose § test_perry_itself_passes_its_own_
+id_checks`) — so "the result document cannot itself move the number" is a
+claim worth measuring rather than assuming. It does not: 4/3 at both tips, the
+same four by name, `3119` and `3145` unchanged.
+
+**The one thing that cannot be closed by construction:** the last commit on
+this branch is the one adding this table, so no run in it hashes the tree that
+contains it. The md5 bracket in each row is of the tree at the moment of that
+run, and the only delta from the final tree is these rows.
+
+**The same four by name on all three trees**, and none is in a file this branch
+touches:
+
+- `test_diagnose § test_the_queue_register_reconciles_with_the_queue_on_this_repository`
+- `test_diagnose § test_perry_itself_passes_its_own_id_checks`
+- `test_heading_title § test_none_of_them_contains_its_own_id`
+- `test_kr_progress_provenance § test_no_current_in_the_payload_claims_to_be_a_measurement`
+
+**No `test_host_support`.** § 5.3's flake did not recur in any of the three
+runs. Round 2 saw it once, on a first run in a fresh `main` worktree, and read
+5 across 4 where I read 4 across 3 on the same `main` content an hour or so
+later. My baseline is 4/3, it is the number in the table, and the flake is
+reported present-or-absent rather than reconciled away.
+
+**The counting trap, reproduced on my own logs before I trusted any of them.**
+On all three, the three readings disagree:
+
+    grep -c '^FAIL:'                          -> 3    (wrong: a header was eaten)
+    the "✗ N module(s) red" line              -> 3    (right, but it counts MODULES)
+    sum of the `FAILED (failures=N)` lines    -> 4    (the failure count)
+
+The eaten header is `test_diagnose`'s first, and it is verifiably eaten rather
+than absent: `test_the_queue_register_reconciles_with_the_queue_on_this_
+repository` appears in every log as a bare traceback line, its `FAIL:` header
+gone above the 25-line window. `test_diagnose` reports `FAILED (failures=2)`
+and shows one header. This is TASK-251 and it is still open.
+
+**`3119 < 3124` is not a regression, and the arithmetic closes exactly.**
+Exactly one module differs each way:
+
+    diff <(ls main/tests/test_*.py) <(ls branch/tests/test_*.py)
+    < test_register_substitution.py     (TASK-243's; the branch predates it)
+    > test_tree_guard.py                (this row's)
+
+Counted directly: `test_register_substitution` is **26** tests on `main` today
+(round 2 said 22, which was true of an earlier tip — corrected here because the
+figure is checkable and I checked it), `test_tree_guard` is **21**. So
+`3124 − 26 + 21 = 3119` on the branch, and `3124 + 21 = 3145` merged. Both
+observed numbers, to the test. `test_task_writer` is 281 on both trees, so the
+call-site fix neither added nor removed a case.
+
+**Merge probe.** `git merge coding/task-249-suite-writes` into `main` @
+`7ef27db`: clean, `ort`, 6 files, no conflicts. Nothing in
+`test_register_substitution` reddens under the merge and nothing this branch
+adds reddens against the newer `main`.
+
+### 8.7 What I could not verify this round
+
+1. **`main` moved under me, and I did not re-run it.** My baseline is
+   `1274587`; `main` was `7ef27db` by the time I merged. The delta is one PMO
+   record commit touching `.perry/events.jsonl`, `perry/BOARD.md`,
+   `perry/intake.jsonl` and one journal file — `git diff --name-only 1274587
+   7ef27db -- tests bin` is empty, so the code under test is byte-identical.
+   But three of the four failures are **data-dependent on board state**, which
+   that commit changes, so strictly my `main` figure is for `1274587`'s board
+   and the merge probe's is for `7ef27db`'s. Both read 4; I did not run a
+   fourth suite to prove the board edit is inert.
+2. **One run per tree.** The four agree by name across three independent
+   trees, which is why I did not repeat. A single run cannot tell a fifth flake
+   from a real failure.
+3. **`--serial` was not run.** All three used the default parallel path.
+4. **I did not reproduce the original write.** Same position as round 2: the
+   sweep is idempotent and this tree is already swept, so a clean run cannot
+   re-derive the defect. § 4's M8 on a seeded copy remains the evidence.
+5. **The subagent-worktree scenario is shown, not observed in the wild.** § 8.5
+   demonstrates `.claude/` appearing between snapshot and verify in a temp
+   tree. I did not catch a real subagent doing it during a real run.
+6. **The narrow docstring pin is narrow.** It cannot tell whether the bullet's
+   description is *accurate*, only which of two named mechanisms it claims. A
+   third mechanism invented tomorrow would satisfy `exactly one` only by
+   accident, and the test would need extending — it says so itself.
+7. **I invalidated my own first tip run and had to discard it.** I edited two
+   files in `wt-249` while that run's step 0 snapshot was open; the guard would
+   have reported them, correctly, as the suite's tree moving under it. I killed
+   the run rather than report a red I caused, finished every edit, committed,
+   and re-ran on a tree that then stayed still. Recorded because it is the
+   cheapest possible demonstration that step 0 does what § 0 claims, and
+   because the alternative — reporting that run — is exactly the failure this
+   row exists to prevent.
+
+## 9. Round 3 V4 — PASS, one bullet blocking the merge, four to fix or file
+
+Round 3 (`perry/evidence/2026-08/TASK-249-round3-v4-review.md`) PASSed the row,
+re-derived nine mutations of its own at 9/9 red, attacked the docstring pin
+seven ways, and blocked the merge on a single bullet. All five items are closed
+below. **Three of the five fixes were themselves green under the first mutation
+I aimed at them**, and that is § 9.6 rather than something smoothed away.
+
+Everything destructive here ran on a `tar` copy of the branch tip in a scratch
+directory, never on a reviewed tree. `perry/BOARD.md`, `perry/tasks.jsonl` and
+`.perry/events.jsonl` were not touched; no write-side Perry tool was run; no
+identifiers were minted; `perry-conform declare` and `perry-tasks render` were
+never invoked.
+
+### 9.1 The blocker — the widest hole was missing from the list of holes
+
+`tests/tree_guard.py`'s **"What it does NOT catch, said plainly"** had six
+bullets and `.claude` / `.gstack` were not among them, while `.DS_Store` and
+`__pycache__` — strictly narrower holes — each had one. § 8.4 of this document
+calls the `.claude` hole the widest of the five. A list whose job is to state
+the holes, omitting the widest while naming two smaller ones, reads as
+complete; that is worse than no list.
+
+**The bullet is written from scope I re-derived rather than from the row's own
+account, and the real scope is bigger than § 8.4 recorded.** Three experiments
+in temp trees, each with `compare()` returning `[]`, each with a control:
+
+| # | what happens | manifest before | `compare()` |
+|---|---|---|---|
+| 1 | `.claude/worktrees/agent-1/f` and `.gstack/cache` created between snapshot and verify | `['perry', 'perry/BOARD.md']` | `[]` — **including no `+ .claude   (created)`** |
+| 2 | `.claude/` **already present** at snapshot; `settings.local.json` rewritten and `hooks.json` created | `['perry', 'perry/BOARD.md']` — `.claude` is not in it at all | `[]` |
+| 3 | `perry/evidence/.claude/TASK-0NN-result.md` and `perry/.gstack/tasks.jsonl` written | `['perry', 'perry/BOARD.md', 'perry/evidence']` | `[]` |
+| C | control: the same writes into `perry/evidence/.claudex/` and `perry/BOARD.md` | same | `['  M perry/BOARD.md   (changed)', '  + perry/evidence/.claudex   (created)', '  + perry/evidence/.claudex/TASK-0NN-result.md   (created)']` |
+
+Row 1 is the mechanism § 8.4 argues from — and `+ .claude` itself is invisible
+because `os.walk`'s `dirnames` are filtered *before* the loop that records
+directory entries (`tree_guard.py:198-204`). **Rows 2 and 3 are the part the
+row's prose did not convey.** Row 2 is the one that matters: the story told in
+§ 8.4 is "a subagent worktree appears mid-run and is skipped", which sounds
+bounded in time; the truth is that once the directory exists, *nothing under it
+is ever in the manifest*, so a test rewriting the agent harness's own
+permission allowlist reports nothing. Row 3 is the ignore matching on the
+**name at any depth** — `perry/evidence/.claude/` is as invisible as
+`./.claude/` — which the `#:` comment above `IGNORE_DIRS` does say and which no
+example in the prose showed. The control makes it the name match and not the
+experiment.
+
+All three are in the new bullet, numbered, with the control named.
+
+**And the fix is pinned, because a documentation fix that nothing checks is the
+next round's defect.** `test_every_ignored_name_is_a_bullet_in_the_list_of_
+what_is_missed` asserts that every entry of `IGNORE_DIRS`, `IGNORE_NAMES` and
+`IGNORE_SUFFIXES` appears in that section. Deleting the new bullet is red
+(MB1). Adding a fifth ignored directory **with the equality pin moved with it**
+— the realistic way a red run is made green — is red too (MB2), which the
+equality pin alone would not have caught.
+
+### 9.2 The pin claimed more than it reads
+
+`TestTheDocstringSaysWhichMechanismShipped` said it read *which mechanism
+shipped*. It reads which of two **strings** is present in `tests/run`. Round 3
+produced three green mutations that ship the other mechanism and two bullet
+rewrites that describe the shipped one backwards. **I reproduced all five on my
+own copy before changing anything**, whole-module, baseline GREEN (21 tests):
+
+| # | mutation | the pin's 2 tests | rest of the module |
+|---|---|---|---|
+| G1 | re-aim spelled `export "PERRY_PROJECT=$ROOT"` ahead of the refusal | **GREEN** | RED (4) |
+| G2 | `PERRY_PROJECT="$ROOT"` then a bare `export PERRY_PROJECT` | **GREEN** | RED (4) |
+| G3 | `unset PERRY_PROJECT`, the whole refusal left dead under `if false` | **GREEN** | RED (4) |
+| G4 | the bullet rewritten to assert the exact OPPOSITE behaviour | **GREEN** | **GREEN (21/21)** |
+| G5 | the bullet cut to `- **A write to a DIFFERENT checkout.** \`tests/run\` refuses.` | **GREEN** | **GREEN (21/21)** |
+
+The accuracy gap is total: what is required is the substring `refuses` present
+and the substring `export` absent, in one bullet, and nothing else.
+
+**Both halves of the instruction are taken.** The claim is narrowed *and* the
+pin is widened as far as a string search can go:
+
+- **Narrowed.** The class is renamed
+  `TestTheBulletUsesTheVocabularyOfTheMechanismSpelledInTestsRun` — it is a
+  vocabulary check on one bullet, and the name now says so. Its docstring
+  states the measurement: G1/G2 are caught today and the *class* of unknown
+  spellings is not; G3 is **not caught and cannot be**, because no substring
+  search distinguishes a reachable line from an unreachable one; G4/G5 are not
+  caught because accuracy is not what it reads. It ends by naming
+  `TestTheEnvironmentTheGuardCanSee` as the protection, which runs the real
+  script and asserts on `rc`.
+- **Widened.** The export pattern stops at the variable name instead of
+  requiring `=`, so `export "PERRY_PROJECT=$ROOT"` and a bare `export
+  PERRY_PROJECT` after an assignment are both seen — G1 and G2 are now RED at
+  the pin (MP1, MP2). The refuse token is anchored to a non-comment line too,
+  which is the symmetry round 3 asked for: `tests/run` discusses both
+  mechanisms at length in comment blocks, and discussing is not shipping.
+
+G3 stays green at the pin (MP3) and is red at the behaviour tests. It is
+recorded in the docstring as the thing this test structurally cannot see,
+rather than left for a fourth round to rediscover.
+
+### 9.3 The `IndexError` is a sentence now
+
+`self._implemented(self.run_src)[0]` raised `IndexError: list index out of
+range` when `tests/run` spelled neither token — an unhandled error in a test
+whose entire value is the sentence it prints. It now asserts `len(found) == 1`
+with its own diagnostic first. Measured (MP6): with both banners reworded so
+neither token is present, the two pin tests come back as **two `FAIL`s carrying
+their explanations and no `IndexError` anywhere in the output**.
+
+One more crash on the same path, found by mutating the fix: `setUp` bounded the
+bullet with `doc.index("\n- **", start + 1)`, so moving that bullet to the end
+of its list raised `ValueError` and **ERRORed both tests** (MP8, measured with
+the pre-fix terminator restored). The first repair — run to the end of the
+docstring — was worse, because it swallows the *"Why a refusal and not a
+re-aim"* section whose prose contains both forbidden words. The terminator is
+now the next top-level bullet **or** the next `##` heading, whichever comes
+first; with the bullet moved last the pin is green and nothing raises (MP7).
+
+### 9.4 Case-differing spellings, and the relative paths the fix newly accepted
+
+Round 3's sharp edges A and B are one decision about what "this tree" means.
+
+**A — still falsely refused.** `pwd -P` collapses symlinks but does not
+canonicalise case, and neither does `Path.resolve()`. On this case-insensitive
+filesystem `$ROOT` spelled in another case `cd`s into the same real directory;
+`perry-task` would compute the same differently-cased string and write into
+that same real directory, inside the tree step 0 hashes — and the resolved
+comparison turned it away. That is the same false refusal § 8.3 was raised to
+close, one spelling further out.
+
+**B — newly accepted, and it is a regression the fix introduced.** At `8dfd25e`
+a raw comparison refused `.` and `tests/..`; `cd … && pwd -P` accepts them
+because `tests/run` resolves against **its own** cwd, while `perry-task`
+resolves against **each subprocess's** and tests routinely pass `cwd=` a temp
+directory. Round 3 could not construct a live escape in this suite and named it
+a residual.
+
+**The decision, made explicit rather than left incidental:**
+
+1. **Sameness is inode identity, not string equality.** The comparison is
+   `test "$PERRY_PROJECT" -ef "$ROOT"` — same device, same inode. That is the
+   question the guard actually asks: would an un-rooted write land inside the
+   tree step 0 hashes? It is true for every casing the filesystem folds
+   together, and it asserts nothing about filesystems that do not fold them.
+2. **A relative value is refused before the comparison is reached.** A value
+   whose meaning is whichever cwd reads it cannot be certified by a check whose
+   whole job is to say where the writes will land. It is refused with its own
+   banner — `refusing to run: PERRY_PROJECT is a relative path` — because
+   telling someone who typed `PERRY_PROJECT=.` inside `$ROOT` that it "points
+   somewhere else" is worse than useless.
+
+Re-swept, `bash tests/run --lint` in a copy, all seventeen spellings round 3
+enumerated (rc 2 before step 1 = REFUSED):
+
+| # | spelling | before | now | right? |
+|---|---|---|---|---|
+| 1 | `$ROOT` exactly | ACCEPTED | ACCEPTED | yes |
+| 2 | `$ROOT/` trailing slash | ACCEPTED | ACCEPTED | yes |
+| 3 | symlink alias of `$ROOT` | ACCEPTED | ACCEPTED | yes |
+| 5 | `$ROOT/.` | ACCEPTED | ACCEPTED | yes |
+| 6 | doubled slash | ACCEPTED | ACCEPTED | yes |
+| 7 | `$ROOT/tests/..` | ACCEPTED | ACCEPTED | yes |
+| 8 | **`.` (relative, cwd is `$ROOT`)** | ACCEPTED | **REFUSED** | **fixed** |
+| 9 | **`tests/..` (relative)** | ACCEPTED | **REFUSED** | **fixed** |
+| 10 | `..` (relative, parent) | REFUSED | REFUSED | yes |
+| 11 | **the whole path UPPERCASED** | REFUSED | **ACCEPTED** | **fixed** |
+| 12 | **the last component case-flipped** | REFUSED | **ACCEPTED** | **fixed** |
+| 13 | a genuinely foreign directory | REFUSED | REFUSED | yes |
+| 14 | a path that does not exist | REFUSED | REFUSED | yes |
+| 15 | a **file**, not a directory | REFUSED | REFUSED | yes |
+| 16 | the empty string | ACCEPTED | ACCEPTED | yes — matches `… or Path.cwd()` |
+| 17 | a subdirectory of `$ROOT` | REFUSED | REFUSED | yes |
+| 18 | `$ROOT` with a trailing space | REFUSED | REFUSED | yes |
+
+Four changed, all four in the intended direction, and it did not become
+accept-everything: 10, 13, 14, 15, 17 and 18 are still refused.
+
+Two tests, one per class. `test_a_differently_cased_spelling_of_this_root_is_
+this_root` skips itself where the filesystem is case-SENSITIVE — there the two
+spellings really are two directories and refusing is right — and it did not
+skip on this machine. `test_a_relative_perry_project_is_refused_and_says_why`
+asserts both halves, refused and explained.
+
+### 9.5 `24` and `18` are out of the docstring
+
+`tests/test_tree_guard.py`'s count docstring carried a present-tense `24` /
+`18` that nothing checked, inside the test whose stated reason for existing is
+that *a number in a comment is a claim nothing checks*. § 8.2's claim that the
+number was gone from both places was true of the assertions and false of the
+prose. The sentence now says the old number was wrong, that writing today's
+count here would be the same defect one value later, and names the two
+instruments without their answers. `grep -n '\b24\b\|\b18\b' tests/test_tree_
+guard.py` returns nothing.
+
+`tests/tree_guard.py:188`'s *"eleven"* is left: it is historical, describes a
+value that was wrong, and carries no live count. Round 3 agreed.
+
+### 9.6 Mutations — twenty, and four of them were green
+
+Two sets. **Set A reproduces round 3's five attacks on the unfixed tip**
+(§ 9.2's table). **Set B is fifteen mutations of the fixes themselves**, on a
+fresh `tar` copy of the fixed tip (`.git`, `__pycache__`, `*.pyc`, `*.pyo`
+excluded), never on a reviewed tree.
+
+Discipline, enforced by the harness rather than remembered: refuse to start on
+a copy that is not byte-identical to the tip; assert the baseline **GREEN**
+before the first mutation and re-assert it after the last; assert every anchor
+**present and unique** before replacing; clear `__pycache__` and sleep past the
+whole-second boundary before every run (CPython validates bytecode on
+mtime-in-whole-seconds plus size); restore from the captured original bytes and
+assert **md5 equality**; and `diff -rq` the whole copy against the tip at the
+end. Runner: `python3 -m unittest discover -s tests -p test_tree_guard.py`
+with `PERRY_PROJECT` popped — deliberately not through `tests/run --only`,
+whose 25-line truncation eats `FAIL:` headers (TASK-251).
+
+| # | mutation | verdict | test(s) that died |
+|---|---|---|---|
+| MC1 | `-ef` reverted to the § 8.3 resolved-string comparison | RED | `test_a_differently_cased_spelling_of_this_root_is_this_root`, **alone** |
+| MC2 | every absolute path accepted | RED | `test_a_foreign_perry_project_refuses_the_run` + `test_other_spellings_…` ×3 |
+| MD1 | relative values resolved instead of refused | RED | `test_a_relative_perry_project_is_refused_and_says_why` (both spellings) |
+| MD2 | the relative banner reworded to "points somewhere else" | RED | the same |
+| MP1 | re-aim spelled `export "PERRY_PROJECT=$ROOT"` ahead of the refusal | RED | **both pin tests** + 6 behaviour |
+| MP2 | `PERRY_PROJECT="$ROOT"` then a bare `export PERRY_PROJECT` | RED | **both pin tests** + 6 behaviour |
+| MP3 | `unset PERRY_PROJECT`, the refusal left dead in the file | RED | 6 behaviour — **the pin stays GREEN** |
+| MP4 | the bullet asserts the opposite behaviour | **GREEN** | — |
+| MP5 | the bullet cut to four words | **GREEN** | — |
+| MP6 | `tests/run` spells neither mechanism | RED | both pin tests, as **FAILs with sentences, no `IndexError`** |
+| MP7 | the bullet moved to the end of its list | GREEN | — (correct: the pin still reads the bullet, nothing raises) |
+| MP8 | the same move with the **pre-fix** terminator restored | RED | both pin tests **ERROR** with `ValueError` |
+| MB1 | the `.claude` / `.gstack` bullet deleted | RED | `test_every_ignored_name_is_a_bullet_…` (`.claude`, `.gstack`) |
+| MB2 | a fifth ignored dir added **with the equality pin moved with it**, no bullet | RED | the same (`.ruff_cache`) |
+| MV1 | all three ignore lists emptied | RED | the same, on the non-empty guard |
+
+**MC1 repeats round 3's MR-1/MR-3 finding one layer out**, and it is the most
+useful row here: a full revert of the `-ef` comparison to the string comparison
+this branch shipped in round 2 kills **exactly one test, and it is the new
+one**. `test_other_spellings_of_this_root_are_this_root` — round 2's own fix
+test — is green under it, because none of the six spellings it passes is
+case-differing. The same blindness, one round later, caught by the same method.
+
+**The four green mutations, reported rather than counted around.**
+
+- **MP4 and MP5 are the § 9.2 finding.** They are green because the pin does
+  not read accuracy, and its docstring now says so in those words. They were
+  green before this round too (G4, G5); what changed is that the test no longer
+  claims otherwise.
+- **MP3 is green and cannot be made red by a string search.** A refusal left in
+  the file but unreachable still reads as shipped. The behaviour tests kill it.
+- **MP7 is green and should be**: the terminator fix makes the bullet readable
+  wherever it sits, and MP8 is the control that shows the fix is load-bearing.
+
+### 9.7 Three of my own fixes were green under their first mutation
+
+Recorded because "I mutated every fix" is worth nothing without the ones that
+came back green.
+
+1. **`test_a_relative_perry_project_is_refused_and_says_why` asserted
+   `"relative" in out`** and stayed GREEN when the refusal banner was reworded
+   to "points somewhere else" — the explanatory paragraph below the banner
+   still contained the word. It now reads the line containing `refusing to
+   run`, which is the line a reader acts on. MD2 is red against the tightened
+   version.
+2. **`setUp`'s terminator**, above.
+3. **`test_every_ignored_name_is_a_bullet_…` iterated three sets** and would
+   have passed on three empty ones. It asserts the derived set is non-empty
+   first; MV1 is that assertion firing.
+
+And one failure of my own harness, which the discipline caught rather than
+hid: a mutation making **two edits to the same file** captured the "original"
+bytes once per edit, so the restore wrote back the state after the first edit.
+The tree looked restored — every md5 check compared the file against the bytes
+it had just written. `diff -rq` of the whole copy against the tip is what
+caught it, and it is why that diff is in the checklist above and not just at
+the end. The affected copy was rebuilt from the tip and every mutation on it
+re-run; no reviewed tree was ever involved.
+
+### 9.8 Baselines — four full suites, measured here, in this session
+
+**I took no number from the brief.** Five full suites. `bash tests/run` from each worktree root
+with `PERRY_PROJECT` unset, bracketed at both ends by `git ls-files -z | xargs
+-0 md5 -q | md5 -q` and by `git status --porcelain`. Machine shared with other
+agents' runs and two of these ran concurrently — wall times are recorded, not
+comparable.
+
+**`main` moved again during this round**, from `1cbc025` to `4d21513` (three
+PMO/record commits and one new evidence document; `git diff --name-only
+1cbc025 4d21513 -- tests bin schema viewer templates setup` is empty, so no
+code under test changed). I measured **both** board states rather than assume
+the second inert, and the merge probe is against the newer one.
+
+| tree | modules | tests | seconds | **failures** | red modules | step 0 | tracked md5 (pre → post) |
+|---|---|---|---|---|---|---|---|
+| `main` @ `1cbc025` | 104 | 3124 | 247.6 | **4** | 3 | n/a (no guard on `main`) | `2cd8b847…` → `2cd8b847…` |
+| `main` @ `4d21513` | 104 | 3124 | 309.0 | **4** | 3 | n/a | `f61f323c…` → `f61f323c…` |
+| branch tip `df8d536` | 104 | **3122** | 301.6 | **4** | 3 | `✓ nothing under … moved` | `61695daf…` → `61695daf…` |
+| merge probe `52e6089` (`4d21513` + `df8d536`) | 105 | **3148** | 243.6 | **4** | 3 | `✓ nothing under … moved` | `bc291799…` → `bc291799…` |
+| branch tip `e374307` — **the tree containing this section** | 104 | **3122** | 229.9 | **4** | 3 | `✓ nothing under … moved` | `347c9b81…` → `347c9b81…` |
+
+`git status --porcelain` empty at both ends of all five.
+
+**The counting rule, and the trap reproduced on my own logs before I trusted
+any of them.** On all five runs the three readings disagree the same way:
+
+    grep -c '^FAIL:'                          -> 3    (wrong: a header was eaten)
+    the "✗ N module(s) red" line              -> 3    (right, but it counts MODULES)
+    sum of the `FAILED (failures=N)` lines    -> 4    (the failure count)
+
+`errors=` was zero on all five and is summed separately. The eaten header is
+`test_diagnose`'s first: `test_the_queue_register_reconciles_with_the_queue_
+on_this_repository` appears in every one of the five logs as a bare traceback
+line with no `FAIL:` header above it, while `test_diagnose` reports `FAILED
+(failures=2)` and prints one header. `tests/parallel:283` is the mechanism and
+it is TASK-251, still open.
+
+**The same four by name on all five runs**, and none is in a file this branch
+touches:
+
+- `test_diagnose § test_the_queue_register_reconciles_with_the_queue_on_this_repository`
+- `test_diagnose § test_perry_itself_passes_its_own_id_checks`
+- `test_heading_title § test_none_of_them_contains_its_own_id`
+- `test_kr_progress_provenance § test_no_current_in_the_payload_claims_to_be_a_measurement`
+
+**No `test_host_support`** in any of the five (`grep -c` returns 0 on each
+log). The known intermittent did not recur; that is evidence about its rate,
+not proof it is gone.
+
+**The arithmetic closes exactly, re-derived here.** `diff` of the two
+`tests/test_*.py` listings shows one module each way: `test_register_
+substitution.py` on `main` only, `test_tree_guard.py` on the branch only.
+Counted directly with `python3 -m unittest discover`: `test_register_
+substitution` is **26**, `test_tree_guard` is now **24** — 21 at `03493d6`
+plus the two spelling tests of § 9.4 and the documentation pin of § 9.1. So
+`3124 − 26 + 24 = 3122` on the branch and `3124 + 24 = 3148` merged. Both
+observed to the test.
+
+**Merge probe.** `git merge coding/task-249-suite-writes` into `main` @
+`4d21513`: clean, `ort`, 6 files, no conflicts, `52e6089`. The failure count
+moves nowhere.
+
+### 9.9 What I could not verify this round
+
+1. **The last row of § 9.8's table is added by a commit whose only content is
+   that row**, so no run hashes the exact bytes of the final tree. This is the
+   one thing that cannot be closed by construction, and it is one paragraph
+   smaller than it was: the `e374307` run is on the tree that already contains
+   all of § 9 except this sentence and its table row. Two of the four failures
+   scan evidence documents, so "the result document cannot move the number" is
+   a claim worth measuring rather than assuming — and it is now measured on
+   this branch four times (§ 8.6 twice, § 9.8's `df8d536` and `e374307`),
+   reading 4 / 3 and 3122 tests before and after 388 lines of document.
+2. **One run per tree, five runs.** The four failures agree by name across all
+   five, which is why I did not repeat. A single run cannot separate a
+   fifth flake from a real failure.
+3. **`--serial` was not run.** All five used the default parallel path.
+4. **I did not reproduce the original write**, for the same reason as rounds
+   2 and 3: the sweep is idempotent and every tree here is already swept.
+   § 4's M8 on a seeded copy is still the evidence.
+5. **`test_task_writer`'s count was not re-derived this round.** Round 3
+   measured 281 on both trees; the module takes ~95 s and my attempt to count
+   it standalone timed out against a machine already running two suites.
+   Nothing in this round's diff touches it — `git diff --stat 03493d6..HEAD`
+   is `tests/run`, `tests/tree_guard.py`, `tests/test_tree_guard.py` and this
+   file — and the suite totals close without it.
+6. **MP3 stays green and I did not close it.** A refusal left in the file but
+   unreachable reads as shipped to any string search. It is stated in the
+   pin's docstring as a structural limit and the behaviour tests kill it; I
+   did not attempt shell reachability analysis in a test.
+7. **The relative-path decision is a judgement, not a measurement.** Round 3
+   could not construct a live escape through an accepted relative
+   `$PERRY_PROJECT` in this suite, and neither did I. I refused the class
+   because its meaning depends on who reads it, not because I caught it
+   escaping.
+8. **The case fix is asserted only where the filesystem folds case.** The new
+   test skips itself on a case-sensitive filesystem, and this machine's is
+   case-insensitive, so the skip path is reasoned and not exercised. `-ef` is
+   the right answer on both kinds; only one kind was measured.
+9. **I did not observe a real subagent worktree appearing during a real run.**
+   § 9.1's three rows are the mechanism in temp trees, with controls.
+10. **I did not audit the rest of `tests/tree_guard.py`'s prose** against the
+    code. I fixed the one list round 3 blocked on, the one bullet the pin
+    reads, and the count docstring; I did not check every sentence.
+11. **I did not touch `perry/BOARD.md`, `perry/tasks.jsonl` or
+    `.perry/events.jsonl`.** The PMO owns them. TASK-251 (the 25-line
+    truncation) is still open and still not mine to take mid-round.

+# TASK-249 — round 2 V4 review (delta on the corrections)
+
+- **Branch / tip reviewed**: `coding/task-249-suite-writes` @ `8dfd25e`
+- **Baseline tree**: `main` @ `5367c06` (main moved to `70bf490` mid-round; `tests/` and `bin/` are byte-identical between the two, so the baseline still stands)
+- **Merge probe**: `main` @ `70bf490` + branch, `ort`, clean, no conflicts
+- **Reviewer**: fresh-context V4, read-only. Every experiment ran in my own worktrees and in a `tar`-copy under the scratchpad. **The reviewed tree was never modified**; `git status --porcelain` was empty at both ends of every suite run and the tracked-file md5 bracket matched.
+- **Verdict: PASS**, with two documentation defects (one material) and two sharp edges named below. Nothing I found makes the guard fail to do what the row claims it does.
+
+---
+
+## 0. What I measured, and with what
+
+Machine: macOS 26.5.2, Python 3.11.15, 14 cores, **shared with other agents' suite runs** — wall times are recorded, not comparable.
+
+Failure counting rule, obeyed: **sum of the per-module `FAILED (failures=N)` lines**. Command used on every log:
+
+```
+grep -o 'FAILED (failures=[0-9]*\(, errors=[0-9]*\)\?)' <log>
+```
+
+I confirmed the trap on my own `main` log before trusting anything: `grep -c '^FAIL:'` returned **4** where the `FAILED (…)` sum was **5**, and `✗ N module(s) red` said **4** (modules). Three readings, one right. `tests/parallel:283` is the mechanism, as the branch says.
+
+| tree | modules | tests | seconds | **failures** | red modules | tree guard | tracked-file md5 |
+|---|---|---|---|---|---|---|---|
+| `main` @ `5367c06`, fresh worktree, first run | 104 | 3124 | 292.9 | **5** | 4 | n/a (no guard on main) | `21ea2073…` → `21ea2073…` unchanged |
+| branch tip `8dfd25e` | 104 | 3115 | 313.1 | **4** | 3 | `✓ nothing under … moved` | `3e2a1e25…` → `3e2a1e25…` unchanged |
+| merge probe (`70bf490` + branch) | 105 | 3141 | 315.6 | **4** | 3 | `✓ nothing under … moved` | `c5e5cd66…` → `c5e5cd66…` unchanged |
+
+Command in all three cases: `bash tests/run` from the worktree root with `PERRY_PROJECT` unset, bracketed by `git ls-files -z | xargs -0 md5 -q | md5 -q`.
+
+**The four failures are the same by name on the tip and on the merge probe**, and they are a subset of `main`'s five:
+
+- `test_diagnose § test_the_queue_register_reconciles_with_the_queue_on_this_repository`
+- `test_diagnose § test_perry_itself_passes_its_own_id_checks`
+- `test_heading_title § test_none_of_them_contains_its_own_id`
+- `test_kr_progress_provenance § test_no_current_in_the_payload_claims_to_be_a_measurement`
+
+`main`'s fifth was `test_host_support § TestOpenCodeDispatchLimit.test_concurrent_mixed_registers_do_not_exceed_global_cap` — the flake the branch already recorded at `1f7a13f`, in a module this branch does not touch. It did not recur on either of my other two runs.
+
+### Two corrections to the numbers I was handed
+
+1. **The task prompt's baseline — "4 failures across 2 red modules" — has the module count wrong.** It is **3** red modules on the branch's fork point and on the tip (`test_diagnose` ×2, `test_heading_title` ×1, `test_kr_progress_provenance` ×1). The branch's own § 5.1 says 3 and is right; the prompt is the thing that is off. On a *clean `main`* worktree the number is **5 failures across 4 red modules** on a first run, the extra one being the recorded flake.
+2. **`104 → 3115` on the branch versus `104 → 3124` on `main` is not a regression.** The branch was cut before TASK-243 landed and is missing `tests/test_register_substitution.py` (22 tests) while adding `tests/test_tree_guard.py` (17). `diff` of the two `tests/test_*.py` listings shows exactly that one file each way. The merge probe restores it: 105 modules / 3141 tests. Nothing is lost by merging.
+
+---
+
+## (a) The refusal guard — the highest-risk change
+
+**Behaviour, exercised by hand on a copy:**
+
+| environment | result |
+|---|---|
+| `PERRY_PROJECT` unset | runs; step 0 green (all three full runs above) |
+| `PERRY_PROJECT="$ROOT"` | runs; step 0 green |
+| `PERRY_PROJECT=/tmp/somewhere-else` | `rc=2`, refuses **before step 1**, names both paths, and prints `Run it as:  env -u PERRY_PROJECT bash tests/run` |
+| `bash tests/run --lint` | runs step 1 then the trap's step 0 verify, `✓ all green` — the `--lint` early exit really is covered |
+
+The message is actionable: it names the offending value, names `$ROOT`, explains the mechanism in three lines, and gives the exact command to recover. This is the good version of a refusal.
+
+**The companion test is real and it is load-bearing.** Two independent mutations of the condition kill it by name:
+
+- `M-B` — condition replaced with `if true` (refuse everything): `test_perry_project_equal_to_the_root_is_allowed` **FAILS** (along with three others whose inner `tests/run` also gets refused).
+- `M-B2` — condition weakened to `if [ -n "${PERRY_PROJECT:-}" ]` (refuse whenever it is set at all, which is the *plausible* wrong version, not the strawman): **exactly one test dies, `test_perry_project_equal_to_the_root_is_allowed`.** That is the cleanest possible proof that the refusal cannot be satisfied by refusing everything.
+- `M-A` — condition replaced with `if false` (never refuse): `test_a_foreign_perry_project_refuses_the_run` **FAILS**, alone.
+
+So claim 4 holds in both directions.
+
+### Sharp edge 1 — the refusal is string equality against `pwd -P`, and `perry-task` resolves
+
+`tests/run:30` computes `ROOT="$(cd "$(dirname "$0")/.." && pwd -P)"`, and the guard compares `"$PERRY_PROJECT" != "$ROOT"` as raw strings. `bin/perry-task:7283` does `Path(os.environ.get("PERRY_PROJECT") or Path.cwd()).resolve()`. The two disagree about what "the same directory" means. Measured:
+
+```
+PERRY_PROJECT=/tmp/…/mut249     (a symlink alias of $ROOT, realpath-identical)  → REFUSED
+PERRY_PROJECT=/private/tmp/…/mut249/   (trailing slash)                          → REFUSED
+```
+
+Both of those environments are *harmless* — `perry-task` would resolve them to `$ROOT` and write inside the tree step 0 hashes — and the suite refuses to run anyway. On this machine, where worktrees live under `/private/tmp` and `/tmp` is a symlink to it, an agent with `PERRY_PROJECT` spelled the `/tmp` way cannot run the suite at all until it reads the message.
+
+**This fails in the safe direction** (a refusal never produces a wrong answer, and the printed escape hatch works), so it is not a blocker. But it is a false refusal in a guard whose stated cost model is "refusing costs nothing", and the guard's own tests never exercise it — `test_perry_project_equal_to_the_root_is_allowed` passes `str(root.resolve())`, which is precisely the one spelling that cannot trip. A one-line fix (`realpath`/`cd … && pwd -P` on `$PERRY_PROJECT` before comparing) would close it.
+
+---
+
+## (b) Claim 3 — shrinking `IGNORE_DIRS` from six names to two
+
+**The factual half of the claim is true.** `.pytest_cache`, `.mypy_cache`, `.ruff_cache` and `node_modules`:
+
+- zero hits in `git ls-files` (no tracked file, no `package.json`, no `pyproject.toml`, no `requirements*.txt`, no `tox.ini`, no `setup.cfg`, no `.pre-commit-config.yaml`);
+- zero hits on disk under the live checkout (`find … -maxdepth 4`);
+- no tool in the repo makes one — `.github/workflows/ci.yml` installs nothing ("stdlib only") and runs `bash tests/run` on a clean checkout; `.vscode/settings.json` is `{"python.languageServer": "None"}`;
+- the only in-repo mention of `.pytest_cache` is `bin/lib/__init__.py:923`, an unrelated scan-exclusion list inside `perry-diagnose`.
+
+So the deletions match nothing today, and the guard is 811 entries / 0.42 s per walk — the cost is not the issue either.
+
+**But the deletion is internally inconsistent with the file's own stated principle, and I can show the consequence.** In a temp tree, with a cache directory appearing *during* the window between snapshot and verify:
+
+```
+SHIPPED two-name IGNORE_DIRS : ['  + .ruff_cache   (created)', '  + .ruff_cache/0.4.2   (created)']
+DELETED six-name IGNORE_DIRS : []
+```
+
+Nine lines above the deletion, the same docstring justifies excluding `.git` with: *"a guard that is red for reasons the reader did not cause is a guard that gets switched off."* An editor-side `ruff`/`mypy` server, a stray `pytest` in a neighbouring terminal, or a `npx` invocation during a five-minute run is exactly a red the reader did not cause. The four entries cost nothing and were the cheap insurance against it.
+
+**What I could not find is a way for this to make the suite silently wrong.** The failure mode of the deletion is a spurious *red*, never a missed write. On that basis it does not fail the row — but I disagree with the reasoning, and I would restore the four names. "Matches nothing today" and "is a blind spot" are not the same statement: an ignore entry for a directory *no test may legitimately write* is not a blind spot, it is a scope declaration.
+
+**Two directories the ignore list does not name and probably should.** Both exist in the live checkout, both are gitignored, and both are written by tooling rather than by tests:
+
+- `.claude/worktrees/` — `.gitignore` says verbatim "Subagent worktrees — temporary, created by the Agent tool". A subagent spawning a worktree during a suite run turns step 0 red.
+- `.gstack/`
+
+Neither is named in the docstring's "What it does NOT catch, said plainly" list, which is otherwise the best part of the file. They belong there or in `IGNORE_DIRS`.
+
+---
+
+## (c) Claim 2 — is "by consequence" actually load-bearing?
+
+Yes, and I tested it the only way that settles it: **blind a list AND delete the equality assertion that covers it**, then see whether anything still dies.
+
+| mutation | tests killed |
+|---|---|
+| `M-C` `IGNORE_DIRS` += `"perry"` | `test_all_three_ignore_lists_are_the_documented_ones`, `test_the_four_files_of_this_row_are_never_invisible`, `test_a_module_that_writes_into_the_root_turns_the_suite_red` |
+| `M-D` `IGNORE_SUFFIXES` += `".md", ".jsonl"` | same three |
+| `M-E` `IGNORE_NAMES` += `"events.jsonl", "intake.jsonl"` (the exact round-1 defeat) | `test_all_three_ignore_lists_are_the_documented_ones`, `test_the_four_files_of_this_row_are_never_invisible` |
+| **`M-C` + equality pin for `IGNORE_DIRS` replaced with `pass`** | `test_the_four_files_of_this_row_are_never_invisible`, `test_a_module_that_writes_into_the_root_turns_the_suite_red` |
+| **`M-D` + equality pin for `IGNORE_SUFFIXES` replaced with `pass`** | same two |
+| **`M-E` + equality pin for `IGNORE_NAMES` replaced with `pass`** | **`test_the_four_files_of_this_row_are_never_invisible`, alone** |
+
+The last row is the one that matters. With the equality assertion gone — the assertion that "is satisfied by any list" — the consequence test still catches the exact defeat that got past round 1, on its own. Claim 2's load-bearing half is real.
+
+`M-E` is also the round-1 defeat reproduced and closed: the first version left thirteen tests green under it; the tip kills two.
+
+---
+
+## (d) Mutations, re-derived — I did not trust 12/12
+
+Twelve mutations of my own, on a `tar` copy of the tip (`.git`, `__pycache__`, `*.pyc` excluded). Discipline: anchor asserted **present and unique** before replacing; `__pycache__` cleared before every run; a sleep past the whole-second boundary before every run; restore by writing back the captured original and asserting md5 equality against the pre-mutation baseline; **baseline asserted GREEN (17 tests, 6.59 s, rc=0) before the first mutation and re-asserted GREEN after the last**.
+
+Runner: `python3 -m unittest discover -s tests -p test_tree_guard.py -v` in the copy, with `PERRY_PROJECT` popped from the env. I deliberately did **not** count through `tests/run --only`, because the 25-line truncation in `tests/parallel:283` eats the `FAIL:` headers — my first pass through `tests/run` returned unnamed failures for six of twelve mutations, which is the same trap in a smaller room.
+
+| # | mutation | verdict | test that died |
+|---|---|---|---|
+| M-A | `tests/run` refusal condition → `if false` | RED | `test_a_foreign_perry_project_refuses_the_run` |
+| M-B | refusal condition → `if true` | RED | `test_perry_project_equal_to_the_root_is_allowed` (+3) |
+| M-B2 | refusal condition → `if [ -n "$PERRY_PROJECT" ]` | RED | `test_perry_project_equal_to_the_root_is_allowed` |
+| M-C | `IGNORE_DIRS` += `"perry"` | RED | 3 named above |
+| M-D | `IGNORE_SUFFIXES` += `".md", ".jsonl"` | RED | 3 named above |
+| M-E | `IGNORE_NAMES` += the two stores | RED | 2 named above |
+| M-F | mode dropped from the file token | RED | `test_a_permission_change_is_a_change` |
+| M-G | `trap finish EXIT` removed | RED | `test_a_module_that_writes_into_the_root_turns_the_suite_red` (+2) |
+| M-H | `lines = compare(...)` → `lines = []` | RED | `test_the_same_run_is_green_when_the_guard_is_neutered`, `test_verify_is_one_and_names_the_path` (+1) |
+| M-C2 | M-C with its equality pin also removed | RED | `test_the_four_files_of_this_row_are_never_invisible` (+1) |
+| M-D2 | M-D with its equality pin also removed | RED | `test_the_four_files_of_this_row_are_never_invisible` (+1) |
+| M-E2 | M-E with its equality pin also removed | RED | `test_the_four_files_of_this_row_are_never_invisible` |
+
+**12/12 red. No mutation survived.** The agent's own 12/12 is independently corroborated by a different set of twelve, and every one of mine names the test that killed it.
+
+Note `M-H` also kills `test_the_same_run_is_green_when_the_guard_is_neutered` — the mutation-half test asserts the neutered run comes back GREEN, and neutering it twice over is red. That is correct behaviour, not a defect.
+
+---
+
+## (e) Is the retraction complete?
+
+**Yes.** § 5.1 of `perry/evidence/2026-08/TASK-249-result.md` withdraws both halves in bold and in the first sentence — the number *and* the accusation — names the failure its list dropped, and says the project had already filed the right figure. Commit `42e8213`'s message carries the same retraction. I grepped the branch for surviving assertions of the withdrawn claim:
+
+- no occurrence of "3 failures", "failures=3", "uncommitted board edits" or an equivalent claim anywhere in `tests/`, `bin/`, or the result document, other than inside the retraction itself where the old claim is quoted in order to be withdrawn;
+- § 5.2 and § 5.3 both report **4**, and § 5.3's table is consistent with my own measurements;
+- the earlier commits (`1a5dedd`, `1f7a13f`) predate the retraction and their messages do not assert the number.
+
+This is a real retraction, not a deletion. It also does the thing the row was actually about: it explains the mechanism rather than quietly swapping the figure.
+
+### Defect 1 — a *different* withdrawn claim is still standing, in the guard's own docstring (MATERIAL)
+
+`tests/tree_guard.py:60-67`, inside the "What it does NOT catch, said plainly" list:
+
+> **`tests/run` closes the ambient case** by exporting `PERRY_PROJECT="$ROOT"` for the whole run, which pins every un-rooted write into the tree the guard is watching rather than letting it escape to a neighbour.
+
+**`tests/run` does not do this.** It refuses. `tests/run:52-58` and `tests/test_tree_guard.py:136-139` both say so explicitly, and both say exporting was *tried first and rejected* because it reddens nine tests in `test_config_store_readers`. The docstring describes the approach that was withdrawn, and describes it as shipped.
+
+This is not cosmetic in this row. The sentence is in the one list in the codebase whose entire job is to tell the next reader what the guard does and does not cover; it names a *mechanism* (a pin) with different properties from the one that shipped (a refusal); and a reader who believes it will conclude that running with a foreign `PERRY_PROJECT` is safe and silently re-aimed, when in fact the suite will stop dead. Round 1 failed this row partly for a guard that could not fail on the thing it named; this is the documentation equivalent, in the same file, surviving the correction that was supposed to replace it.
+
+Fix is one paragraph. **This is the only finding I would insist be fixed before merge.**
+
+### Defect 2 — "eleven executables", declared and wrong, twice (SMALL)
+
+`tests/tree_guard.py:129` and `tests/test_tree_guard.py:348` both say:
+
+> this repository ships **eleven** executables whose bit is load-bearing
+
+Measured on the tip: **24** files carry mode `100755` in the tree (`git ls-tree -r HEAD | awk '$1=="100755"'`), of which **18** are under `bin/`, plus `setup`, two template linters and three files in `tests/`. On disk: `find . -type f -perm -u+x -not -path './.git/*'` → 24. No grouping I can construct gives eleven.
+
+The result document (§ 6 item 2) says "this repository ships executables whose bit is load-bearing" — no number. So the hedge was applied in the write-up and not in the two places a future reader will actually read. Claim 5 ("file mode recorded as measured, not declared") is true of the *token* — `M-F` proves the mode is really recorded and really pinned — and false of the sentence next to it. In a row whose subject is that numbers must be measured, an invented count sitting in the guard's docstring is the wrong thing to leave behind.
+
+---
+
+## (f) Claim 7 — the report about a file it did not change
+
+**Confirmed, and the characterisation is fair.** `tests/live_state_expectations.py:451-461` reads, verbatim:
+
+```
+"""A Perry tool pointed at this repository, not at a fixture.
+
+A test says which project it means in one of three places, read in
+this order: `--root <dir>`, `cwd=<dir>`, or a state path among the
+arguments. **With none of them the answer is no** — the tool would in
+fact inherit the runner's cwd and so read this repository, but
+`--help` and `--version` runs are the bulk of that population and none
+of them touches state. A stated blind spot, not a claim: say
+`cwd=ROOT` and the guard sees you.
+"""
+```
+
+The row's quote is that sentence with the trailing clause trimmed at the colon; nothing load-bearing is dropped. The implementation matches the docstring (`--root`, then `cwd=` kwarg, then `is_live_path` over the operands, else `False`).
+
+And the characterisation is right: TASK-249's call site was `subprocess.run(["python3", <perry-task>, name], capture_output=True, text=True)` — no `--root`, no `cwd=`, no state path — so `_tool_reads_this_project` returned `False` and the expectation checker looked past it. `intake-sweep` is a genuine counterexample to "none of them touches state". **The file is unchanged on the branch** (`git diff main...8dfd25e` touches six files and this is not one of them), which is the right call: it guards *reads*, not writes, and widening it is a different row.
+
+I did not change it either.
+
+---
+
+## (g) Merge probe
+
+`git merge coding/task-249-suite-writes` into `main` @ `70bf490`: clean, `ort`, 6 files, no conflicts. Full suite on the merged tree: **105 modules · 3141 tests · 315.6 s · 8 workers · 4 failures across 3 red modules** — the same four by name as the tip. Step 0 green (`✓ nothing under … moved`). Tracked-file md5 `c5e5cd66…` identical before and after.
+
+No test in `test_register_substitution` (TASK-243's, absent from the branch) reddens under the merge, and no test the branch adds reddens against the newer `main`.
+
+---
+
+## What I did NOT verify
+
+1. **I did not independently reproduce the original write.** A full `bash tests/run` on a fresh clean `main` worktree left every tracked file byte-identical (`21ea2073…` both ends) and `git status` empty. That is *consistent* with the row's central claim — the sweep is idempotent and this tree has already been swept — but it means my run does not re-confirm the defect from scratch. Four agents and the branch's own before/after md5s at `e322925` are the evidence for that; I checked the reasoning and the call-site fix, not the original write.
+2. **I did not verify the "nine tests in `test_config_store_readers`" figure** behind the decision not to export `PERRY_PROJECT="$ROOT"`. Given Defect 1, the ship *is* the refusal, so the figure is now only a justification for a path not taken — but it is unchecked.
+3. **I did not re-derive the "106 hits" / "88 + 22 = 110" instrumentation figures** in § 1 of the result.
+4. **I did not test the guard against a genuinely concurrent out-of-band writer** on the live checkout (a `ruff` server, a subagent worktree appearing under `.claude/worktrees/`). The `.ruff_cache` demonstration in (b) is the mechanism shown in a temp tree, not that scenario observed in the wild.
+5. **I did not run `--serial`.** All three full runs used the default parallel path.
+6. **I ran each tree's full suite once.** The four failures agreed across three independent trees, which is why I did not repeat; a single run cannot separate a fifth flake from a real failure, and `main`'s fifth is only classified as a flake because the branch's own three re-runs (green/green/red) say so.
+
+---
+
+## Verdict
+
+**PASS.**
+
+Every claim I was asked to attack survived the attack. The refusal guard works in all three environments and its companion test dies under two independent "refuse everything" mutations. The three ignore lists are pinned by consequence as well as by equality, and the consequence half kills the round-1 defeat *with the equality pin removed*. Twelve mutations of my own, independent of the agent's, are 12/12 red with a named test each. The retraction is complete, explicit, and explains the mechanism rather than hiding the error. Claim 7's quote is verbatim and its reading of the blind spot is fair. Merge is clean and moves the failure count nowhere.
+
+**Fix before merge (1 item):**
+
+- **Defect 1** — `tests/tree_guard.py:60-67` still asserts that `tests/run` "closes the ambient case by exporting `PERRY_PROJECT="$ROOT"`". It refuses instead. Replace the paragraph. This is a withdrawn approach described as shipped, in the guard's own statement of what it does not catch.
+
+**Fix, or file (3 items):**
+
+- **Defect 2** — "eleven executables" in `tests/tree_guard.py:129` and `tests/test_tree_guard.py:348`. Measured: 24 (18 under `bin/`). Either state the measured number or drop it, as the result document already does.
+- **Sharp edge 1** — the refusal compares raw strings against `pwd -P` while `perry-task` resolves. A `/tmp` symlink alias or a trailing slash refuses a harmless environment; the guard's own test uses the one spelling that cannot trip. Resolve `$PERRY_PROJECT` before comparing.
+- **Sharp edge 2** — I disagree with the `IGNORE_DIRS` deletion (fails safe, so not a blocker), and `.claude/worktrees/` and `.gstack/` are unnamed in either the ignore list or the "does not catch" list despite both existing in the live checkout and both being written by tooling rather than by tests.
+
+*Checked on copies and in my own worktrees throughout. `perry/BOARD.md` and `perry/tasks.jsonl` untouched; no write-side Perry tool was run against the project or any worktree of it; no identifiers minted.*

+
+- **Branch / tip reviewed**: `coding/task-249-suite-writes` @ `03493d6`
+- **Baselines measured in this session**: `main` @ `7ef27db` and `main` @ `014dc6a`
+  (`main` moved under me too — see § 5)
+- **Merge probes**: `7ef27db` + branch = `425ffea`, and `014dc6a` + branch =
+  `23dfef3`. Both `ort`, clean, 6 files, no conflicts.
+- **Reviewer**: fresh-context V4, read-only. Every experiment ran in my own
+  detached worktrees under the scratchpad and in a `tar` copy of the tip.
+  **No tree under review was modified**; `git status --porcelain` was empty and
+  the tracked-file md5 identical at both ends of every suite run, and the live
+  checkout at `/Users/bytedance/proj/Perry` was never written to. No write-side
+  Perry tool was run against the project or any worktree of it. No identifiers
+  minted. `perry/BOARD.md` and `perry/tasks.jsonl` untouched.
+- **Verdict: PASS**, with one material documentation defect and three sharp
+  edges. Nothing I found makes the guard fail to do what the row claims, and
+  the three round-2 fixes are each real.
+
+---
+
+## 0. What I measured, and with what
+
+Machine: macOS 26.5.2, Python 3.11.15, 14 cores, shared with other agents'
+runs — wall times are recorded, not comparable.
+
+**I took no baseline from the brief.** Counting rule obeyed: the failure count
+is the **sum of the per-module `FAILED (failures=N)` lines**, with `errors=`
+counted separately where present. Command on every log:
+
+```
+grep -o 'FAILED ([a-z=0-9, ]*)' <log>
+grep -o 'failures=[0-9]*\|errors=[0-9]*' <log> | awk -F= '{s[$1]+=$2} END {for (k in s) print k, s[k]}'
+```
+
+**The counting trap reproduced on my own logs before I trusted any of them.**
+On all five runs the three readings disagree the same way:
+
+```
+grep -c '^FAIL:'                       -> 3   (wrong: a header was eaten)
+the "✗ N module(s) red" line           -> 3   (right, but it counts MODULES)
+sum of the `FAILED (failures=N)` lines -> 4   (the failure count)
+```
+
+The eaten header is `test_diagnose`'s first. It is verifiably eaten rather than
+absent: `test_the_queue_register_reconciles_with_the_queue_on_this_repository`
+appears in every log as a bare traceback line
+(`main.log:10`) with no `FAIL:` header above it, while `test_diagnose` reports
+`FAILED (failures=2)` and prints only one header. `tests/parallel:283` is the
+mechanism, filed as TASK-251.
+
+| tree | modules | tests | seconds | **failures** | red modules | step 0 | tracked md5 (pre → post) |

+
+`git status --porcelain` was empty at both ends of all five.
+
+**The same four by name on every tree**, and none is in a file this branch
+touches:
+
+- `test_diagnose § test_the_queue_register_reconciles_with_the_queue_on_this_repository`
+- `test_diagnose § test_perry_itself_passes_its_own_id_checks`
+- `test_heading_title § test_none_of_them_contains_its_own_id`
+- `test_kr_progress_provenance § test_no_current_in_the_payload_claims_to_be_a_measurement`
+
+**No `test_host_support`.** The known intermittent did not recur in any of my
+five runs. My baseline is 4 failures across 3 red modules, and it agrees with
+the row's own `main` figure taken at `1274587` — measured on three different
+board states now (see § 5).
+
+**The test arithmetic closes exactly, re-derived here.** `diff` of the two
+`tests/test_*.py` listings shows exactly one module each way —
+`test_register_substitution.py` on `main` only, `test_tree_guard.py` on the
+branch only. Counted directly with `python3 -m unittest discover`:
+`test_register_substitution` is **26** and `test_tree_guard` is **21** (and
+green standalone, `Ran 21 tests … OK`). So `3124 − 26 + 21 = 3119` on the
+branch and `3124 + 21 = 3145` merged. Both observed to the test. The row's
+correction of round 2's "22" to 26 is right.
+
+---
+
+## 1. The docstring pin — the cleverest thing here, and the most worth breaking
+
+`TestTheDocstringSaysWhichMechanismShipped` claims the two ways to close the
+ambient `$PERRY_PROJECT` case are mutually exclusive, that each leaves a
+distinct token in `tests/run` (a non-comment `export PERRY_PROJECT=` vs the
+`refusing to run: PERRY_PROJECT` banner), that it reads which one shipped,
+requires **exactly one**, and requires the bullet to use that mechanism's word
+and not the other's.
+
+Baseline: the class is GREEN on the tip (2 tests, 0.002 s). Seven attacks,
+each anchored, unique-checked and restored by md5:
+
+| # | attack | pin verdict | whole module |
+|---|---|---|---|
+| P3 | **MD-2 re-run**: a real `export PERRY_PROJECT="$ROOT"` added beside the refusal | **RED** — both tests | — |
+| P7 | **MD-3 re-run**: still refuses, banner reworded to `declining to start` | **RED** — one FAIL, one ERROR | — |
+| P1 | bullet keeps the word "refuses" and asserts the **opposite** behaviour | **GREEN** | **GREEN (21/21)** |
+| P2 | bullet reduced to the four words `**\`tests/run\` refuses.**` | **GREEN** | **GREEN (21/21)** |
+| P4 | re-aim spelled `PERRY_PROJECT="$ROOT"` + `export PERRY_PROJECT` **ahead of** the refusal | **GREEN** | RED (2 behaviour tests) |
+| P5 | re-aim spelled `export "PERRY_PROJECT=$ROOT"` ahead of the refusal | **GREEN** | not run (pin only) |
+| P6 | third mechanism: `unset PERRY_PROJECT`, refusal left in the file but under `if false` | **GREEN** | RED (2 behaviour tests) |
+
+**P3 and P7 confirm the row's MD-2 and MD-3.** The exactly-one assertion really
+does catch the "belt and braces" edit that adds the withdrawn mechanism beside
+the shipped one, and really does catch a refusal that ships neither token. Two
+notes on P7: the complaint arrives as one `FAIL` (`0 != 1 … implements neither`)
+plus one **`IndexError: list index out of range`** from
+`self._implemented(self.run_src)[0]` — an unhandled error rather than a
+diagnostic, in a test whose value is the sentence it prints. Cheap to fix with
+a `skipTest`/guard; it does not change the verdict.
+
+### The admitted accuracy gap is total, and P1/P2 measure how wide
+
+The pin's own docstring says it cannot judge whether the description is any
+good. **It is worth writing down how little it does judge.** P1 rewrites the
+bullet to:
+
+> **`tests/run` refuses to start** when `$PERRY_PROJECT` is UNSET. When it names
+> a completely different checkout the run proceeds and the writes land there,
+> which is safe because the guard follows the variable.
+
+That is the exact inversion of both the shipped behaviour *and* the hazard the
+whole row exists for, and **all 21 tests in the module stay green**. P2 reduces
+the bullet to four words — `**\`tests/run\` refuses.**` — and the module is
+green again. The pin requires the substring `refuses` present and the substring
+`export` absent, in the bullet, and nothing else. Round 2's Defect 1 was a
+bullet that named the wrong mechanism; a bullet that names the right mechanism
+and describes it backwards is not caught. The row says so; I am putting a
+measurement next to the sentence.
+
+### They are not mutually exclusive, and the two tokens are read asymmetrically
+
+`_implemented` looks for the re-aim only on a **non-comment** line
+(`^[^#\n]*\bexport[ \t]+PERRY_PROJECT=`) but looks for the refusal as a **plain
+substring anywhere in the file, comments included**. Two consequences, both
+measured:
+
+- **A live re-aim can be invisible.** P4 (`PERRY_PROJECT="$ROOT"` then a bare
+  `export PERRY_PROJECT`) and P5 (`export "PERRY_PROJECT=$ROOT"`) are ordinary
+  shell spellings of the same statement that the regex does not match. Placed
+  ahead of the refusal they make the refusal unreachable — the variable always
+  equals `$ROOT` by the time it is compared — and the pin reads `["refuse"]`,
+  finds exactly one, sees `refuses` in the bullet, and passes. The shipped
+  mechanism is the re-aim; the pin says it is the refusal.
+- **A dead refusal still reads as shipped.** P6 replaces the guard with
+  `unset PERRY_PROJECT` and leaves the whole refusal block under `if false`.
+  The banner string is still in the file, so the pin reads `["refuse"]` and
+  passes, on a `tests/run` that cannot refuse anything.
+
+**The suite as a whole is not fooled**: P4 and P6 both kill
+`test_a_foreign_perry_project_refuses_the_run` and
+`test_other_spellings_of_this_root_are_this_root`, which run the real script and
+assert `rc=2`. So this is not a hole in the row's protection — it is a hole in
+*this test's* stated claim. The pin does not "read which mechanism shipped"; it
+reads which of two strings is present in a file. Where the two answers diverge,
+the behaviour tests are the ones doing the work.
+
+**And a third mechanism is a real possibility, not a hypothetical.** P6's
+`unset PERRY_PROJECT` genuinely closes the ambient case: with the variable
+gone, `perry-task` falls back to the cwd, which `cd "$ROOT"` already set. It is
+a legitimate design the pin structurally cannot express. § 8.7 item 6 of the
+result says this; P6 is the demonstration.
+
+**One fragility for the next editor.** `setUp` does
+`doc[start:doc.index("\n- **", start + 1)]` — if the *"A write to a DIFFERENT
+checkout"* bullet is ever moved to the end of the "What it does NOT catch" list,
+`str.index` raises `ValueError` and both tests error out. The uniqueness guard
+above it is careful; the terminator is not.
+
+---
+
+## 2. `tests/run`'s root resolution — the highest-blast-radius edit in the row
+
+### It invokes the real script
+
+`run_suite` (`tests/test_tree_guard.py:108-125`) does
+`subprocess.run(["bash", "tests/run", "--only", <module>], cwd=str(root), …)`
+against a `copy_repo` of the repository, with `PERRY_PROJECT` popped from the
+inherited environment and re-set only when a test asks. **It is the real
+entry point, not a reimplementation of its logic** — confirmed by reading, and
+confirmed behaviourally by MR-1/MR-3 below, which change only `tests/run` and
+are seen.
+
+### MR-3 re-run, and the claim about why the old test was blind
+
+On a `tar` copy of the tip, whole module, baseline GREEN (21 tests) before and
+after, restores md5-verified:
+
+| # | mutation of `tests/run` | verdict | test(s) that died |
+|---|---|---|---|
+| MR-1 | comparison reverted to raw strings against `pwd -P` (the `8dfd25e` behaviour) | RED | **`test_other_spellings_of_this_root_are_this_root`, alone** |
+| MR-3 | **the plausible half-fix**: `${PERRY_PROJECT%/}` only, symlinks unresolved | RED | **`test_other_spellings_of_this_root_are_this_root`, alone** |
+
+**`test_perry_project_equal_to_the_root_is_allowed` — the old test — is GREEN
+under both.** That is the row's claim restated as a measurement, and it holds:
+the old test passed `str(root.resolve())`, the one spelling a raw comparison
+cannot trip, so it could not observe the bug it existed to catch. Only the new
+test dies, under the full revert and under the half-fix alike.
+
+### Spellings the six do not cover
+
+`bash tests/run --lint` in the `tar` copy, eighteen values of `$PERRY_PROJECT`
+(`REFUSED` = rc 2 before step 1):
+
+| # | spelling | result | right? |
+|---|---|---|---|
+| 1 | `$ROOT` exactly | ACCEPTED | yes |
+| 2 | `$ROOT/` trailing slash | ACCEPTED | yes (round-2 Sharp edge 1, closed) |
+| 3 | symlink alias of `$ROOT` | ACCEPTED | yes (closed) |
+| 4 | `/tmp` spelling of a `/private/tmp` root | ACCEPTED | yes (closed) |
+| 5 | `$ROOT/.` | ACCEPTED | yes |
+| 6 | `$ROOT` with a doubled slash | ACCEPTED | yes |
+| 7 | `$ROOT/tests/..` | ACCEPTED | yes |
+| 8 | **`.` (relative; cwd is `$ROOT`)** | **ACCEPTED** | **see below** |
+| 9 | **`tests/..` (relative)** | **ACCEPTED** | **see below** |
+| 10 | `..` (relative, parent) | REFUSED | yes |
+| 11 | **the whole path UPPERCASED** | **REFUSED** | **no — false refusal** |
+| 12 | **one component case-flipped** | **REFUSED** | **no — false refusal** |
+| 13 | a genuinely foreign directory | REFUSED | yes |
+| 14 | a path that does not exist | REFUSED | yes, and it says `resolves to = (nothing …)` |
+| 15 | a **file**, not a directory | REFUSED | yes |
+| 16 | the empty string | ACCEPTED | yes — matches `os.environ.get(…) or Path.cwd()` |
+| 17 | a subdirectory of `$ROOT` | REFUSED | yes |
+| 18 | `$ROOT` with a trailing space | REFUSED | yes |
+
+Two findings, both minor, both new to this round.
+
+**Sharp edge A — case-differing spellings are still falsely refused.** This
+filesystem is case-insensitive: `cd /PRIVATE/TMP/…` succeeds, and `pwd -P`
+resolves symlinks but does **not** canonicalise case, so it returns the string
+as typed. `Path(…).resolve()` in CPython does not canonicalise case either — so
+`perry-task` would compute the same differently-cased string and write into the
+**same real directory**, inside the tree step 0 hashes. This is precisely the
+class of false refusal Defect 3 was raised to close, one spelling further out,
+and it survives. The message is also unhelpful here: because
+`PERRY_PROJECT_REAL` equals `$PERRY_PROJECT`, the `resolves to =` line is
+suppressed and the reader is shown two paths that differ only in case with no
+explanation. Low likelihood (nobody types a path in the wrong case), fails safe,
+not a blocker.
+
+**Sharp edge B — the fix newly accepts relative paths, whose meaning is
+cwd-dependent.** At `8dfd25e` a raw comparison refused `.` and `tests/..`;
+`cd … && pwd -P` accepts them, because `tests/run` resolves them against **its
+own** cwd. `perry-task` resolves them against **each subprocess's** cwd, and
+tests routinely set `cwd=` to somewhere else. So `PERRY_PROJECT=.` is a value
+`tests/run` certifies as "this tree" and `perry-task` may read as some other
+tree. In practice the other tree is a `tempfile` directory, which is harmless,
+and I could not construct a case in this suite where it is not — so this is a
+residual to name, not a defect to fix. It is the cost of `cd`-based resolution
+and the row does not mention it.
+
+Neither edge is reachable without deliberately spelling `$PERRY_PROJECT` oddly,
+and both fail in the refuse/harmless direction. The six spellings the new test
+does cover are the ones that were actually observed to bite.
+
+---
+
+## 3. The count — derived, and non-vacuously so
+
+Re-derived with my own commands on the tip:
+
+```
+git ls-tree -r HEAD | awk '$1=="100755"' | wc -l              -> 24
+git ls-tree -r HEAD | awk '$1=="100755" {print $4}' | grep -c '^bin/'  -> 18
+find . -type f -perm -u+x -not -path './.git/*' | wc -l       -> 24
+```
+
+The six outside `bin/` are exactly `setup`, `templates/knowledge-base/bin/
+kb-lint`, `templates/ops/bin/deliverable-lint`, `tests/merge-check`,
+`tests/parallel`, `tests/run` — the six the new test names. 24 / 18 confirmed.
+
+**The number is out of the assertion.** `test_the_executables_this_repository_
+ships_carry_their_mode` derives the set from `TG.manifest(PERRY_HOME)` and
+asserts shape, not size.
+
+**It is not `len(X) == len(X)`.** I broke it in both directions:
+
+| # | mutation of `tests/tree_guard.py` | verdict | test(s) that died |
+|---|---|---|---|
+| MX-1 | `manifest` hardcodes mode `0o777` — **everything** looks executable | RED | `test_the_executables_…_carry_their_mode`, `test_a_permission_change_is_a_change` |
+| MX-2 | `manifest` hardcodes mode `0o644` — the derived set is **empty** | RED | the same two |
+| ME-1 | `chmod -x bin/perry-task` (not one line of Python touched) | RED | `test_the_executables_…_carry_their_mode`, alone |
+
+MX-1 is caught by the `os.access(X_OK)` cross-check — the test does not read
+its own answer back. MX-2 is caught by `assertTrue(execs)` /
+`assertTrue(shipped)` — a degenerate empty set cannot pass. ME-1 is the tree
+change the mode token exists to see, caught by the test that replaced the
+invented count.
+
+**Correction to the brief, and one observation.** The brief asks me to confirm
+the literal number appears in **neither** file. It does appear, twice, in
+docstring prose rather than in any assertion:
+
+- `tests/tree_guard.py:188` — *"It was written here, as **eleven**, and the tree
+  held two dozen"*. Historical, no live count. Fine.
+- `tests/test_tree_guard.py:515-518` — *"`git ls-tree -r HEAD | awk
+  '$1=="100755"' | wc -l` says **24**, **18** of them under `bin/`"*. This is a
+  present-tense count, correct today, that nothing checks — written into the
+  docstring of the test whose stated reason for existing is that *"a number in
+  a comment is a claim nothing checks"*. It carries its instrument, which is
+  more than "eleven" did, and the assertion does not depend on it. I would
+  still cut it, and I record it rather than rule on it.
+
+---
+
+## 4. The `.claude` hole — reproduced, and it is wider than the row's example
+
+Using `tree_guard` directly in temp trees:
+
+**(A) The row's scenario, reproduced verbatim.** A subagent worktree, a
+`.gstack/` and a `.ruff_cache/` all appearing between snapshot and verify:
+
+```
++ .ruff_cache   (created)
++ .ruff_cache/0.4.2   (created)
+```
+
+`.claude/worktrees/agent-1/f` and `.gstack/cache` are invisible, **and so is
+`+ .claude` itself** — `os.walk`'s `dirnames` are filtered *before* the loop
+that records directory entries (`tree_guard.py:198-204`), so the parent is
+never written to the manifest. The row's account of the mechanism is exactly
+right.
+
+**(B) A file written inside an ignored directory is invisible too — yes.** With
+`.claude/` already present at snapshot time, the manifest records only
+`['perry']`: `.claude` is not in it at all. A "test" then rewriting
+`.claude/settings.local.json` — the agent harness's own permission allowlist —
+and creating `.claude/hooks.json` produces `compare() == []`. Nothing reported.
+This is the hole § 8.4 and § 7 item 5 take knowingly, and it is real.
+
+**(C) The ignore is by name at any depth, which the row's examples do not
+show.** A directory named `.claude` or `.gstack` **anywhere** in the tree is
+skipped whole. Writes to `perry/evidence/.claude/TASK-0NN-result.md` and
+`perry/.gstack/tasks.jsonl` both produce `compare() == []`. Control: the same
+writes to `.claudex/` and `perry/BOARD.md` are reported normally, so the
+mechanism is the name match and not the experiment.
+
+No such path exists in the repository today, and `bin/perry-diagnose:94` and
+`bin/lib/__init__.py:922` already skip `.claude` at any depth, so the choice is
+internally consistent. The `#:` comment above `IGNORE_DIRS` does say "matched by
+name at any depth". It is a widening of the hole beyond the root-level harness
+directory the prose argues for, and worth one clause.
+
+### Defect 1 (MATERIAL) — the widest hole is missing from the list whose job is to name the holes
+
+`tests/tree_guard.py`'s **"What it does NOT catch, said plainly"** list has six
+bullets: the idempotent write, the different checkout, `.git`, `__pycache__` /
+`*.pyc` / `*.pyo`, `.DS_Store`, and the reverted write. **`.claude` and
+`.gstack` are not among them.** They are explained forty lines lower, in a new
+section titled *"What is ignored, and the one rule that decides it"* — which
+reads as a justification of the ignore list, not as a statement of what the
+guard misses.
+
+`.DS_Store` and `__pycache__` — strictly narrower holes — each get a bullet.
+The row's own § 8.4 calls the `.claude` hole *"a real hole and … the widest of
+the five"*, and § 7 item 5 of the result document records it properly. The
+**evidence document is complete; the code is not**, and the code is what the
+next reader consults.
+
+This is round-2 Defect 1's shape one turn later: the one list in the codebase
+whose entire job is to tell the next reader what is uncovered, not telling them.
+Round 2 asked for `.claude`/`.gstack` "there or in `IGNORE_DIRS`"; the row read
+that as a choice and took `IGNORE_DIRS`. I read the list's own opening sentence
+— *"They are listed so that the next reader inherits the list rather than
+rediscovering it"* — as settling it the other way. **Fix is one bullet.**
+
+---
+
+## 5. The two gaps the row declares
+
+### (a) `main` moved mid-round, and the board-dependent failures — closed, from a third board state
+
+The row's § 8.7 item 1 is honest and the gap is real: its `main` baseline is
+`1274587`, its merge probe is against `7ef27db`, the delta between them is a
+PMO record commit that changes `perry/BOARD.md`, `perry/tasks.jsonl`,
+`.perry/events.jsonl` and a journal file, and **three of the four failures read
+board state**. It did not run a fourth suite to prove the board edit inert.
+
+I have now run that suite, and then a fifth, because `main` moved again under
+me — from `7ef27db` to `014dc6a`, two more record commits, `git diff
+--name-only 7ef27db 014dc6a -- tests bin schema viewer` empty, `perry/BOARD.md`
+and `perry/tasks.jsonl` changed again.
+
+So the branch has now been measured against **three different board states**:
+
+| board state | `main` full suite | merge probe with the branch |
+|---|---|---|
+| `1274587` | 4 failures / 3 red (the row's § 8.6) | — (the row did not probe this board) |
+| `7ef27db` | **4 / 3 (mine)** | 4 / 3 — the row's `f069a51` and `67a6f80`, and **mine, `425ffea`** |
+| `014dc6a` | **4 / 3 (mine)** | **4 / 3 (mine, `23dfef3`)** |
+
+Same four failures by name in every one of those runs; `104 modules / 3124
+tests` on every `main` and `105 / 3145` on every merge, to the test. **The board
+edits are inert with respect to the failure count**, measured rather than
+assumed, across two successive record commits that each touched `perry/BOARD.md`
+and `perry/tasks.jsonl`. The board-dependence of three of the four failures is
+real — it is why the caveat was right to write down — but the row's missing
+fourth run is now supplied: `main` @ `7ef27db` reads 4 / 3, which is the board
+state its own merge probes ran on, and `main` @ `014dc6a` reads 4 / 3 as well.
+
+**The gap is closed and the row's numbers stand.** I would add one line to
+§ 8.7 item 1 saying so, rather than leave the caveat standing.
+
+### (b) The contaminated run it discarded
+
+§ 8.7 item 7 self-reports editing two files in `wt-249` while a run's step 0
+snapshot was open, killing that run rather than reporting the red it had caused.
+
+**This strengthens the numbers rather than undermining them, and it should be
+read that way.** The alternative — reporting a red the author created — is the
+precise failure mode this row exists to prevent, and the discipline that
+detected it is the guard the row shipped. The five runs in this document and the
+five in the row's § 8.6 are all on trees whose tracked-file md5 was identical at
+both ends, with `git status --porcelain` empty; a contaminated run cannot hide
+inside that bracket. I checked for residue: nothing on the branch carries a
+figure from the discarded run, and § 8.6's table is consistent with my own five
+measurements taken independently.
+
+### (c) One figure round 2 left unverified, now verified
+
+Round 2 did not check the "nine tests in `test_config_store_readers`" figure
+behind the decision not to export. On a `tar` copy of the tip:
+
+```
+env -u PERRY_PROJECT python3 -m unittest discover -s tests -p test_config_store_readers.py
+  -> Ran 44 tests in 1.647s   OK
+PERRY_PROJECT=<copy>  python3 -m unittest discover -s tests -p test_config_store_readers.py
+  -> FAILED (failures=7, errors=2)          (9 `FAIL:`/`ERROR:` headers)
+```
+
+**Nine, exactly as stated**, and the docstring is right to spell it as 7 + 2
+because `grep -c '^FAIL:'` on that output returns 7. The exported run also
+rendered `.perry/config.md` in the copy, as the docstring says.
+
+One precision point on that last clause: the render is **idempotent** — I
+diffed the whole copy against the tip afterwards and it is byte-identical, so
+the tree guard would *not* have reported it. Calling it "the mechanism in
+miniature" is therefore half right: it is the write, but it is the class of
+write the guard's own first declared blind spot excludes. A clause, not a
+defect.
+
+---
+
+## 6. Mutations — nine of my own, plus the seven in § 1
+
+On a `tar` copy of the tip (`.git`, `__pycache__`, `*.pyc` excluded), never on
+a reviewed tree. Discipline, enforced by the harness rather than remembered:
+refuse to start on a dirty copy; **baseline asserted GREEN (21 tests, rc=0)
+before the first mutation and re-asserted GREEN after the last**; every anchor
+asserted **present and unique** before replacing; `__pycache__` cleared and a
+sleep past the whole-second boundary before every run; restore by writing back
+the captured original bytes and asserting **md5 equality**. Runner:
+`python3 -m unittest discover -s tests -p test_tree_guard.py -v` with
+`PERRY_PROJECT` popped — deliberately not through `tests/run --only`, whose
+25-line truncation eats `FAIL:` headers.
+
+| # | mutation | verdict | test(s) that died |
+|---|---|---|---|
+| MR-1 | `tests/run` comparison reverted to raw strings | RED | `test_other_spellings_of_this_root_are_this_root` |
+| MR-3 | half-fix `${PERRY_PROJECT%/}`, symlinks unresolved | RED | `test_other_spellings_of_this_root_are_this_root` |
+| P4* | re-aim in a regex-evading spelling, ahead of the refusal | RED | `test_a_foreign_perry_project_refuses_the_run`, `test_other_spellings_…` |
+| P6* | `unset PERRY_PROJECT`, refusal left dead under `if false` | RED | the same two |
+| ME-1 | `chmod -x bin/perry-task` | RED | `test_the_executables_…_carry_their_mode` |
+| MX-1 | `manifest` hardcodes `0o777` (everything executable) | RED | that one + `test_a_permission_change_is_a_change` |
+| MX-2 | `manifest` hardcodes `0o644` (derived set empty) | RED | the same two |
+| MI-1 | `.claude` dropped from `IGNORE_DIRS` | RED | `test_all_three_ignore_lists_are_the_documented_ones` |
+| MI-2 | `perry` smuggled **into** `IGNORE_DIRS` (the list GREW) | RED | that one + `test_the_four_files_of_this_row_are_never_invisible` + `test_a_module_that_writes_into_the_root_turns_the_suite_red` |
+
+**9/9 red, no survivors**, baseline GREEN at both ends, every restore
+md5-verified, and the copy byte-identical to the tip afterwards (`diff -rq`,
+no output). This is an independent set from the row's nine and from round 2's
+twelve; MR-3, ME-1 and MI-1 overlap by design because the brief asked for them
+re-run, and all three reproduce.
+
+**Four of them are worth more than the count.**
+
+- **MR-1 and MR-3 both kill exactly one test, and it is the new one.** The old
+  `root.resolve()` test is green under a full revert to the buggy comparison.
+  The row's explanation of why the old test was blind is confirmed, not assumed.
+- **MX-2 is the vacuity check the brief asked for.** A derivation that produced
+  an empty set would pass a `len(X) == len(X)` test; here `assertTrue(execs)`
+  fires. MX-1 is the other direction, caught by the `os.access` cross-check.
+- **MI-2 is the direction that matters** — a list that grew — and it is caught
+  three ways, including by consequence.
+- **P4\* and P6\* are green mutations, and that is the § 1 finding.** They are
+  red only because the *behaviour* tests fire; the pin that claims to read which
+  mechanism shipped reads both as "refuse".
+
+---
+
+## 7. What I did NOT verify
+
+1. **I did not reproduce the original write.** Same position as round 2 and as
+   the row: the sweep is idempotent and every tree I ran is already swept, so a
+   clean run cannot re-derive the defect. § 4's M8 on a seeded copy is the
+   evidence; I checked the call-site fix by reading it and by confirming that
+   `--root` wins over `$PERRY_PROJECT` in `bin/perry-task:7282`
+   (`Path(args.root)… if args.root else Path(os.environ.get("PERRY_PROJECT")
+   or Path.cwd()).resolve()`).
+2. **One run per tree, five trees.** The four failures agree by name across all
+   five, which is why I did not repeat. A single run cannot separate a fifth
+   flake from a real failure, and the absence of `test_host_support` in five
+   runs is evidence about that flake's rate, not proof it is gone.
+3. **`--serial` was not run.** All five used the default parallel path.
+4. **I did not observe a real subagent worktree appearing during a real run.**
+   § 4's (A) is the mechanism in a temp tree, as the row says.
+5. **I did not re-derive § 1's instrumentation figures** ("106 hits",
+   "88 + 22 = 110").
+6. **I did not audit the rest of `tests/tree_guard.py`'s prose** against the
+   code. § 1 measures how little the pin covers; I checked the one bullet the
+   pin reads and the `IGNORE_DIRS` paragraphs, not every sentence.
+7. **Sharp edge B is reasoned, not exploited.** I did not find a test in this
+   suite where an accepted relative `$PERRY_PROJECT` actually sends a write
+   outside `$ROOT`; I am reporting the divergence between the two resolution
+   rules, not a live escape.
+8. **P5 was run against the pin class only**, not the whole module. P4 is the
+   same edit in a different spelling and I ran that one whole-module; I am
+   naming the shortcut rather than reporting P5's module result as measured.
+9. **I did not verify the `.claude`/`.gstack` decision against future intent** —
+   only that nothing is tracked under either today (`git ls-files .claude
+   .gstack` is empty on both `main` and the tip) and that no test in the suite
+   writes there.
+
+---
+
+## Verdict
+
+**PASS.**
+
+All three round-2 fixes are real and each is load-bearing. The resolution fix
+closes every spelling round 2 found refused, and MR-1/MR-3 show the new test —
+and only the new test — is what catches a revert or a half-fix, which is the
+row's own claim about the old test's blindness confirmed by measurement. The
+count is genuinely derived and non-vacuous in both directions. The retraction
+and the two recorded decisions are complete. Nine mutations of mine are 9/9 red
+with a named test each, baseline green at both ends. The merge is clean against
+two successive `main` tips and moves the failure count nowhere: 4 across 3, the
+same four by name, on five independent trees.
+
+**Fix before merge (1 item):**
+
+- **Defect 1** — `.claude` and `.gstack` are absent from `tests/tree_guard.py`'s
+  **"What it does NOT catch, said plainly"** list, while `.DS_Store` and
+  `__pycache__` — strictly narrower holes — each have a bullet. The row's own
+  § 8.4 calls this the widest of the five holes. One bullet, saying that
+  anything under a directory named `.claude` or `.gstack`, **at any depth**, is
+  invisible to the guard, including the directory's own creation.
+
+**Fix, or file (4 items):**
+
+- **The pin's claim is stronger than the pin.** `TestTheDocstringSaysWhich
+  MechanismShipped` reads which of two *strings* is in `tests/run`, not which
+  mechanism shipped: a live re-aim spelled `export "PERRY_PROJECT=$ROOT"` or
+  `PERRY_PROJECT=…; export PERRY_PROJECT` is invisible to the regex, and a
+  refusal left dead under `if false` still reads as shipped. Either anchor the
+  refuse token to a non-comment line too (symmetry with the export check), or
+  narrow the docstring's claim to what it does. Both P4 and P6 are caught by the
+  behaviour tests, so this is a documentation-of-the-test issue, not a hole.
+- **P7's second failure is an `IndexError`**, not a message. Guard
+  `self._implemented(...)[0]`.
+- **Sharp edge A** — case-differing spellings of `$ROOT` are still falsely
+  refused (`cd` succeeds, `pwd -P` does not canonicalise case, and neither does
+  `Path.resolve()`), and the refusal suppresses its `resolves to =` line in
+  exactly that case, showing the reader two paths that differ only in case with
+  no explanation.
+- **`24` / `18` in `tests/test_tree_guard.py:516`** is a present-tense count in
+  a comment, in the docstring of the test whose reason for existing is that a
+  count in a comment is a claim nothing checks. It carries its instrument and
+  nothing depends on it; I would still cut it.
+
+*Every experiment ran on copies or in my own detached worktrees. `perry/BOARD.md`
+and `perry/tasks.jsonl` untouched; no write-side Perry tool was run against the
+project or any worktree of it; `perry-conform declare` and `perry-tasks render`
+were never invoked; no identifiers minted.*

+# TASK-249 — round 4 V4 review (the delta `03493d6 → f8bc100`, confirmed)
+
+- **Branch / tip reviewed**: `coding/task-249-suite-writes` @ `f8bc100`
+- **Scope**: the delta from `03493d6` to `f8bc100` only — five commits,
+  four files (`tests/run`, `tests/tree_guard.py`, `tests/test_tree_guard.py`,
+  `perry/evidence/2026-08/TASK-249-result.md`). I did not re-derive what
+  round 3 confirmed.
+- **Baseline measured in this session**: `main` @ `4716e39`. It did **not**
+  move during this round — `git rev-parse HEAD` on the live checkout read
+  `4716e39` at the start and at the end.
+- **Merge probe**: `4716e39` + `f8bc100` = `4f93630`, `ort`, clean, 6 files,
+  no conflicts.
+- **Reviewer**: fresh-context V4, read-only. Every experiment ran in my own
+  detached worktrees under the scratchpad, in `git archive` copies of the tip,
+  and on a case-sensitive disk image I created. **No tree under review was
+  modified.** The live checkout at `/Users/bytedance/proj/Perry` was never
+  written to (`git status --porcelain` empty, HEAD `4716e39`, at both ends).
+  No write-side Perry tool was run against the project or any worktree of it;
+  `perry-conform declare` and `perry-tasks render` were never invoked; no
+  identifiers minted; `perry/BOARD.md` and `perry/tasks.jsonl` untouched.
+- **Verdict: PASS.** The round-3 blocker is closed by a test that is red both
+  ways the brief asked for. The two behaviour changes in `tests/run` are both
+  correct and neither is accept-everything nor refuse-anything-unusual. All
+  three `df8d536` fixes are genuinely closed, each demonstrated by a paired
+  revert. The four open green mutations are each open for a true reason.
+  The final tree is byte-identical to git's own objects for `f8bc100`.
+  **This row merges.**

+## 0. Baselines, counted the way the brief requires
+
+The failure count is the **sum of the per-module `FAILED (failures=N)` lines**.

+`✗ N module(s) red` line reads 3 and counts MODULES. All three logs show the
+same disagreement, so the trap round 3 documented reproduces here:
+
+```

+sum                                          -> 4      (the failure count)
+grep -c '^FAIL:'                             -> 3      (a header was eaten)
+the "✗ N module(s) red" line                 -> 3      (right, but MODULES)
+errors=                                      -> 0      (a different word)

+- `test_heading_title § test_none_of_them_contains_its_own_id`
+- `test_kr_progress_provenance § test_no_current_in_the_payload_claims_to_be_a_measurement`
+
+**No `test_host_support`.** The known intermittent did not recur in my three
+runs.
+
+**The test arithmetic closes to the test.** `git ls-tree` of both trees differs
+by exactly one module each way: `test_register_substitution.py` on `main` only,
+`test_tree_guard.py` on the branch only. Counted directly on `main`,
+`test_register_substitution` is **26**; `test_tree_guard` on the tip is **24**
+(round 3 measured 21 — the delta adds three tests). So `3124 − 26 + 24 = 3122`
+on the branch and `3124 + 24 = 3148` merged. Both observed exactly.
+
+**The branch moves the failure count nowhere: 4 across 3 red modules, the same
+four by name, on all three trees.**

+
+## 1. The blocker's pin — the main thing, and it holds
+
+`test_every_ignored_name_is_a_bullet_in_the_list_of_what_is_missed` reads the
+`## What it does NOT catch, said plainly` section of `tests/tree_guard.py`'s
+docstring, derives `sorted(IGNORE_DIRS | IGNORE_NAMES | IGNORE_SUFFIXES)`,
+asserts the derived set is non-empty, and requires each name to appear in that
+section.
+
+Nine mutations on a `git archive` copy of the tip, baseline GREEN (24 tests)
+asserted before the first and after the last, every anchor asserted present and
+unique, `__pycache__` cleared and a sleep past the whole-second boundary before
+every run, restore verified against **git's own blob shas** for `f8bc100`:
+
+| # | mutation | verdict | test(s) that died |
+|---|---|---|---|
+| B1 | the `.claude` / `.gstack` bullet **deleted** | **RED** | `test_every_ignored_name_…`, alone (2 subTests) |
+| B2 | a fifth ignored dir `.venv`, **the equality pin moved with it**, no bullet | **RED** | the same, alone |
+| B3 | B2 **+ a truthful bullet, in the wrong section** (*What is ignored*) | **RED** | the same, alone |
+| B9 | a fifth `IGNORE_NAMES` entry `notes.txt`, names pin moved with it | **RED** | the same, alone |
+| B8 | control: B2 **+ a truthful bullet in the right section** | GREEN | — (correct: the honest fix passes) |
+| B4 | B2 + a bullet that **names `.venv` and describes it backwards** | **GREEN** | — |
+| B5 | ignored dir `.claudex` — **no bullet at all** | **GREEN** | — |
+| B6 | `IGNORE_SUFFIXES += ".md"` (blinds `perry/BOARD.md`), suffix pin moved with it | **RED** | `test_the_four_files_of_this_row_are_never_invisible`, `test_a_module_that_writes_into_the_root_turns_the_suite_red` — **not** the new pin |
+| B7 | a **fourth** ignore mechanism, inline in `manifest` (`and d != "evidence"`) | **GREEN** | — |
+
+**B1 and B2 are the two cases the brief named, and both are red.** B2 is the
+one that matters: adding `.venv` to `IGNORE_DIRS` *and* moving
+`test_all_three_ignore_lists_are_the_documented_ones`'s equality set with it —
+the edit that defeats the equality pin alone — is caught by the new test and by
+nothing else. The blocker is genuinely closed.
+
+**B3 and B9 close two ways round it I tried.** A bullet placed in the adjacent
+*"What is ignored, and the one rule that decides it"* section does not satisfy
+the test: the section is bounded at the next `\n## `. And the pin covers all
+three lists, not just `IGNORE_DIRS`.
+
+### Three ways to satisfy the new test without a truthful bullet
+
+All three are green, and the row does not name any of them.
+
+- **B4 — a bullet that names the directory and lies about it.** The bullet
+  *"`.venv`. Fully hashed like any other directory; every write under `.venv`
+  is reported, so nothing is missed here"* — the exact inversion of what the
+  entry means — is green. This is the same shape as MP4/MP5 on the sibling
+  pin, which the delta *did* stop overstating; here it is unstated.
+- **B5 — no bullet at all.** Adding `.claudex` to `IGNORE_DIRS` is green,
+  because the section already contains the literal string `.claudex/` — in the
+  `.claude` bullet's own control sentence, *"The same writes into `.claudex/`
+  are reported"*, which is now the opposite of the truth. The assertion is
+  `assertIn(name, section)`: a **substring** of the section, not a bullet.
+  The test's name says *is a bullet in the list*; what it checks is *appears
+  somewhere in the section*.
+- **B6 — a name that is a substring of the prose.** `IGNORE_SUFFIXES += ".md"`
+  blinds the guard to every markdown file in the tree, including
+  `perry/BOARD.md` — the file this row's real defect moved — and the new pin
+  is **green**, because `TASK-0NN-result.md` appears in the section. It is
+  caught, twice, by `test_the_four_files_of_this_row_are_never_invisible` and
+  by the planted-write test. **The layering works**; the new pin is not what
+  catches it.
+
+**B7 is the one gap with no backstop.** An ignore added *outside* the three
+lists — one line in `manifest`'s `os.walk` filter — is invisible to the new
+pin, to the equality pin, and to the four-files test, as long as it does not
+hide one of those four files. `test_the_four_files_of_this_row_are_never_invisible`'s
+docstring says it catches "a fourth list invented tomorrow"; it catches one
+only when the fourth list hides one of the four named files. That claim is
+bounded rather than wrong, and it predates this delta.
+
+**Judgement.** The blocker is closed: the edit that actually happened, and the
+edit that defeats the equality pin, are both red. The residue is that the test
+is satisfiable by a substring rather than by a bullet, and its name and
+docstring do not say so — the same "the name claims more than the assertion
+reads" shape that round 3 made the delta fix on the *other* pin. **Fix or
+file, not a blocker.**
+
+---
+
+## 2. `tests/run` — the two behaviour changes, swept
+
+Both changes are in the suite entry point, so every future run goes through
+them. Sweep re-run from scratch on a `git archive` copy at `f8bc100`, `bash
+tests/run --lint`, `REFUSED` = rc 2 with a banner before step 1.
+
+| # | spelling | round 3 (`03493d6`) | **round 4 (`f8bc100`)** | right? |
+|---|---|---|---|---|
+| 1 | `$ROOT` exactly | ACCEPTED | **ACCEPTED** | yes |
+| 2 | `$ROOT/` trailing slash | ACCEPTED | **ACCEPTED** | yes |
+| 3 | symlink alias of `$ROOT` | ACCEPTED | **ACCEPTED** | yes |
+| 4 | `/tmp` spelling of a `/private/tmp` root | ACCEPTED | **ACCEPTED** | yes |
+| 5 | `$ROOT/.` | ACCEPTED | **ACCEPTED** | yes |
+| 6 | doubled slash | ACCEPTED | **ACCEPTED** | yes |
+| 7 | `$ROOT/tests/..` | ACCEPTED | **ACCEPTED** | yes |
+| 8 | `.` (relative, cwd is `$ROOT`) | ACCEPTED | **REFUSED — "is a relative path"** | **changed, and right** |
+| 9 | `tests/..` (relative) | ACCEPTED | **REFUSED — "is a relative path"** | **changed, and right** |
+| 10 | `..` (relative parent) | REFUSED | **REFUSED — "is a relative path"** | yes |
+| 11 | the whole path UPPERCASED | REFUSED (false) | **ACCEPTED** | **changed, and right here** |
+| 12 | one component case-flipped | REFUSED (false) | **ACCEPTED** | **changed, and right here** |
+| 13 | a genuinely foreign directory | REFUSED | **REFUSED — "points somewhere else"** | yes |
+| 14 | a path that does not exist | REFUSED | **REFUSED**, `resolves to = (nothing …)` | yes |
+| 15 | a **file**, not a directory | REFUSED | **REFUSED** | yes |
+| 16 | the empty string | ACCEPTED | **ACCEPTED** | yes — matches `os.environ.get(…) or Path.cwd()` |
+| 17 | a subdirectory of `$ROOT` | REFUSED | **REFUSED** | yes |
+| 18 | `$ROOT` with a trailing space | REFUSED | **REFUSED** | yes |
+
+Exactly the two intended movements, and nothing else moved.
+
+### Twelve spellings the sweep does not cover
+
+| # | spelling | verdict | note |
+|---|---|---|---|
+| E1 | **firmlink** `/System/Volumes/Data$ROOT` | ACCEPTED | same dev+inode, a different string, **no symlink in the path** — the nearest thing to a bind mount this machine allows. `stat -f '%d %i'` identical on both. |
+| E2 | a symlink whose **name contains a newline** | ACCEPTED | the quoting holds; `-ef` resolves it |
+| E3 | `$ROOT` with a **trailing newline** | REFUSED | correct — a different path |
+| E4 | leading double slash `//private/tmp/…` | ACCEPTED | POSIX-legal spelling of `$ROOT` |
+| E5 | through a **symlinked parent component** | ACCEPTED | correct |
+| E6 | `$ROOT/./` | ACCEPTED | correct |
+| E7 | uppercased **+ trailing slash** | ACCEPTED | correct on this filesystem |
+| E8 | uppercase via the `/tmp` spelling (two foldings at once) | ACCEPTED | correct |
+| E9 | a value that looks like a `test` operator (`/ -o /x`) | REFUSED | **no operand injection** — `[ … -ef … ]` sees one word |
+| E10 | `$ROOT/tests/../tests/..` | ACCEPTED | correct |
+| E11 | a single space | REFUSED — "relative" | correct |
+| E12 | a single tab | REFUSED — "relative" | correct |
+| E13 | an unexpanded `~/proj/Perry` | REFUSED — "relative" | refuses safely; see the nit below |
+
+**So the refusal did not become accept-everything** (13, 14, 15, 17, 18, E3,
+E9 all refused) **and it did not become refuse-anything-unusual** (5, 6, 7, 16,
+E1, E2, E4, E5, E6, E10 all accepted). I could not make a true second mount
+point of one filesystem on this machine — `hdiutil` will not attach an image
+twice — so E1's firmlink is the strongest same-inode-different-string case I
+have, and `pwd -P` canonicalises it back to `/private/…`, so it does not
+discriminate `-ef` from the string comparison. Hard links to directories are
+forbidden, so there is no hardlinked alias to test.
+
+### MC1 re-run — the `-ef` revert kills exactly one test, and it is the new one
+
+| # | mutation of `tests/run` | verdict | test(s) that died |
+|---|---|---|---|
+| **MC1** | `-ef` reverted to round 2's resolved-**string** comparison, relative branch kept | **RED** | **`test_a_differently_cased_spelling_of_this_root_is_this_root`, alone** |
+| MC2 | the relative branch removed (relatives fall through to `-ef`) | RED | `test_a_relative_perry_project_is_refused_and_says_why`, alone |
+| MC3 | still refuses relatives, **banner** reworded to "points somewhere else" | RED | the same, alone |
+| MC4 | full revert to the raw-string comparison of `8dfd25e` | RED | that one + the case test + `test_other_spellings_of_this_root_are_this_root` |
+| MS1 | the two `case` arms **inverted** (absolute → "relative") | RED | the case test, the relative test, `test_other_spellings_…`, `test_perry_project_equal_to_the_root_is_allowed` |
+
+**MC1 confirmed.** Round 3's finding one layer out: the six spellings round 2's
+own fix test covers are all case-identical, so it is green under a full revert
+of the `-ef` change; only the new test sees it. This is the third time in this
+row that a fix's own test could not observe the bug the next fix closes, and
+the third time the new test is the only one that can.
+
+### The case fix is exercised on a case-SENSITIVE filesystem — the skip path is no longer only reasoned
+
+I created a case-sensitive APFS image (`hdiutil create -fs "Case-sensitive
+APFS"`), mounted it at `/Volumes/CSPERRY`, unpacked the tip there, and pointed
+`TMPDIR` at it so `tempfile.TemporaryDirectory()` — which is where the test's
+copy actually lives — landed on that volume.
+
+```
+env -u PERRY_PROJECT TMPDIR=/Volumes/CSPERRY/tmp python3 -m unittest discover \
+    -s tests -p test_tree_guard.py
+  -> Ran 24 tests   OK (skipped=1)
+  skipped 'this filesystem is case-sensitive, so
+           /Volumes/CSPERRY/tmp/tmpc6lc3diu/REPO is not
+           /Volumes/CSPERRY/tmp/tmpc6lc3diu/repo'
+```
+
+The skip fires, names both paths, and the other 23 tests — including the
+`-ef`-dependent `test_other_spellings_of_this_root_are_this_root` and the
+relative refusal — stay green there. And the **behaviour** on that volume is
+the right one, which is the part the skip cannot assert:
+
+```
+CS: $ROOT exactly                        ACCEPTED
+CS: $ROOT uppercased (a REAL other dir)  REFUSED  ✗ … points somewhere else
+CS: /Volumes/CSPERRY/REPO (nonexistent)  REFUSED  ✗ … points somewhere else
+CS: $ROOT/ trailing slash                ACCEPTED
+CS: relative .                           REFUSED  ✗ … is a relative path
+```
+
+So `-ef` is not "accept any casing": it accepts exactly the casings the
+filesystem folds, and refuses them where it does not. That is what the
+docstring claims, and it is now measured on both kinds of filesystem rather
+than argued on one. **Round 3's sharp edge A is closed, and the row's
+"reasoned, not exercised" caveat can be struck.**
+
+**Sharp edge B is closed too, by decision.** Relative values were the
+regression round 3 caught; they are now refused, with a banner that says it is
+the relativity and not a wrong directory. Nothing in this repository exports a
+relative `PERRY_PROJECT` — I grepped every producer — so the refusal costs
+nothing here.
+
+---
+
+## 3. The three `df8d536` fixes — each closed, each demonstrated by a paired revert
+
+The test of a fix is not that the fix is green; it is that reverting the fix
+turns the attack green again. Each row below is a pair.
+
+| # | mutation | verdict | reading |
+|---|---|---|---|
+| MC3 | banner reworded, **fixed** assertion | **RED** | the fix fires |
+| F1c | banner reworded, assertion reverted to its `df8d536^` text | **GREEN** | the green mutation the row self-reports, reproduced |
+| F1d | assertion reverted, banner untouched (control) | GREEN | the revert is otherwise inert |
+| F2 | the *DIFFERENT checkout* bullet **moved to the end of its list** | **GREEN** | correct — the pin still reads its own bullet |
+| F2c | the same move + terminator reverted to v1 (`doc.index`) | **RED** | both pin tests **ERROR** with `ValueError` |
+| F2c2 | the same move + terminator reverted to v2 (run to end of docstring) | **RED** | `test_the_bullet_uses_the_word_…` fails — the swallowed *"Why a refusal and not a re-aim"* section contains `export` |
+| F3 | all three ignore lists **emptied** | **RED** | `test_every_ignored_name_…` among 7 |
+| F3c | the same, vacuity guard reverted | RED elsewhere, **`test_every_ignored_name_…` GREEN** | the guard is what stops three empty sets passing |
+
+All three are genuinely closed, and F2c/F2c2 show the terminator fix had to be
+*both* halves — the first repair traded a `ValueError` for a wrong reading.
+
+### The same shape elsewhere in the module — one instance, harmless
+
+`test_a_foreign_perry_project_refuses_the_run` asserts `rc == 2` and
+`assertIn("refusing to run", out)` — the generic prefix, not the banner. There
+are now **two** banners. MS1 (the `case` arms inverted, so every absolute path
+prints the *relative* banner) leaves that test **green**; it is red only
+because four sibling tests fire. So the module contains one more assertion that
+would accept the wrong sentence, and it is the one the tightened relative test
+is now asymmetric with. Nothing hides behind it — MS1 is caught four ways —
+but if the two banners are worth distinguishing in one test they are worth
+distinguishing in its sibling. **One line.**
+
+Nothing else in the module matches the shape: I read every `assertIn` /
+`assertNotIn` / `assertTrue` in the file. The remaining string assertions are
+against the guard's own report lines (`M perry/BOARD.md`, `+ .perry/…`,
+`nothing under`, `THE SUITE WROTE INTO THE TREE IT RAN IN`), which are outputs,
+not prose.
+
+---
+
+## 4. The four green mutations left open — each judged
+
+- **MP4 / MP5 (bullet inverted; bullet cut to four words) — reproduced GREEN,
+  and leaving them open is right.** The class was renamed from
+  `TestTheDocstringSaysWhichMechanismShipped` to
+  `TestTheBulletUsesTheVocabularyOfTheMechanismSpelledInTestsRun`, and the
+  docstring now spells out that it requires `refuses` present and `export`
+  absent "and nothing else", with the two mutations named. The claim is now
+  equal to what the code does, which is what round 3 asked for. **Sound.** The
+  same shape is now unstated one class down — see B4/B5 in § 1.
+- **MP3 (`unset PERRY_PROJECT`, refusal left dead under `if false`) —
+  reproduced: the pin stays GREEN, and the behaviour tests kill it** (6
+  failures across `test_a_foreign_perry_project_refuses_the_run`,
+  `test_a_relative_perry_project_is_refused_and_says_why`,
+  `test_other_spellings_of_this_root_are_this_root`). The argument is
+  structurally true: no substring search distinguishes a reachable line from an
+  unreachable one, and the docstring says so in those words. **Sound.**
+- **MP7 (the bullet moved last) — reproduced GREEN, and it should be**
+  (my F2), with a control that shows the terminator fix is load-bearing. The
+  row's MP8 restores the **original** `doc.index` terminator and gets a
+  `ValueError` — my F2c reproduces it. The *intermediate* repair
+  (`doc[start:]` to the end of the docstring) is described in § 9.7 but is not
+  in the mutation table; my F2c2 supplies it, and it fails differently — a
+  wrong reading rather than a crash. **Sound, and the fix needed both
+  halves.**
+
+**MP1 / MP2 re-run on the delta and both are now RED on both pin tests**, so
+the widened `RE_AIM` really does close the two spellings round 3 slipped past
+it. One cost of the widening, which I found and the row does not name:
+
+- **MS2 — a false positive the next editor can trip.** Adding one help line to
+  the refusal's own message, `echo "  or: export PERRY_PROJECT=\"$ROOT\" first"`,
+  turns **both pin tests red** with *"tests/run spells ['re-aim', 'refuse']"*.
+  The anchor is "not a comment line", and an `echo` inside the refusal is not a
+  comment. The edit ships neither mechanism; the message says it ships both.
+  Fails red, so it is a nuisance rather than a hole, and the shape predates the
+  delta (the old pattern would also have matched that line). **File.**
+
+---
+
+## 5. The harness defect the row self-reports — the final tree is genuinely unmodified
+
+The row reports that one of its mutations made two edits to one file, captured
+"original" bytes once per edit, and restored only to the state after the first;
+every md5 check compared the file to bytes the harness had just written, and
+only `diff -rq` against the tip caught it.
+
+**I verified `f8bc100` against git's own objects, not against any digest the
+row produced.**
+
+1. `git ls-tree -r f8bc100` gives a blob sha for every tracked path. I ran
+   `git hash-object` on each corresponding file and compared. Done against a
+   fresh `git archive f8bc100 | tar -x` reference: **zero mismatches**.
+2. The row's own worktree, `scratchpad/wt-249`, is at `f8bc100` with
+   `git status --porcelain` **empty** (no modifications, no untracked files),
+   and `diff -rq --exclude=.git --exclude=__pycache__` against that reference
+   is **empty**. Both checked at the start and again at the end of my round.
+3. My mutation copy was `diff -rq`-identical to the reference and
+   `git hash-object`-identical to git's objects after the last restore, and the
+   baseline re-asserted GREEN (24 tests) at the end.
+4. I scanned the tip's three source files for residue from the row's own named
+   mutations — `if false` outside a docstring, hardcoded `0o777` / `0o644`, a
+   live `export PERRY_PROJECT`, `.venv`, `declining to start`. The only hits
+   are inside docstring prose describing the mutations. The delta touches
+   exactly four files and every hunk in `git diff 03493d6 f8bc100` is accounted
+   for by one of the five commit messages.
+
+**No residue. The tree is what the commits say it is.**
+
+---
+
+## 6. Mutations — my own, this round
+
+Twenty-two on `git archive` copies of the tip, never on a reviewed tree.
+Discipline enforced by the harness rather than remembered: **refuse to start
+unless the copy is `diff -rq`-identical to a reference verified file-by-file
+against git's blob shas**; baseline asserted GREEN (24 tests) before the first
+and after the last; every anchor asserted **present and unique** before
+replacing; `__pycache__` cleared and a sleep past the whole-second boundary
+before every run; **restore by writing back `git cat-file blob <sha>` and
+re-checking `git hash-object` against the tree sha** — never against bytes the
+harness wrote, which is the circularity above; whole-copy `diff -rq` after
+each. Runner: `python3 -m unittest discover -s tests -p test_tree_guard.py -v`
+with `PERRY_PROJECT` popped, deliberately not through `tests/run --only`,
+whose 25-line truncation eats `FAIL:` headers (TASK-251).
+
+Red: B1, B2, B3, B9, B6, MC1, MC2, MC3, MC4, MS1, MS2, MP1, MP2, MP3, F2c,
+F2c2, F3 — **17**.
+Green **by design** (controls / stated limits): B8, F1d, F2, MP4, MP5, MP7 —
+and **green as findings**: B4, B5, B7, F1c, F3c.
+
+One harness error of my own, reported rather than hidden: my first F1c reverted
+the assertion but not the message text that referenced `banner`, producing a
+`NameError` rather than the intended comparison. I re-ran it against the exact
+`df8d536^` text; the corrected result is in § 3.
+
+---
+
+## 7. What I did NOT verify
+
+1. **I did not re-derive round 3.** The `.claude` hole's three scopes, the
+   executable-count derivation, the nine `test_config_store_readers` figure,
+   the `manifest`/`compare` unit behaviour, and the call-site fix were checked
+   by rounds 2 and 3 and are outside this round's scope. I read the delta's
+   changes to their docstrings; I did not re-measure the claims.
+2. **One run per tree, three trees.** The four failures agree by name across
+   all three, which is why I did not repeat. A single run cannot separate a
+   fifth flake from a real failure, and `test_host_support`'s absence in three
+   runs is evidence about its rate, not proof it is gone.
+3. **`--serial` was not run.** All three used the default parallel path.
+4. **No true second mount point, and no hardlinked alias.** `hdiutil` will not
+   attach one image twice and directories cannot be hard-linked, so E1's
+   firmlink is as close as I got — and `pwd -P` canonicalises it, so it does
+   not discriminate `-ef` from the string comparison.
+5. **I did not observe a real subagent worktree appearing during a real run.**
+6. **I did not audit the rest of `tests/tree_guard.py`'s prose** against the
+   code, beyond the section the new pin reads and the bullet the old pin reads.
+7. **B7 is a demonstration, not a proposal.** I showed a fourth ignore
+   mechanism is invisible to all three pins; I did not check whether any real
+   edit is likely to take that shape.
+8. **The case-sensitive volume is a disk image, not the machine's own
+   filesystem.** It behaves as a case-sensitive APFS volume (`aa` and `AA` are
+   distinct there, verified) but it is not the environment anyone will actually
+   run in.
+9. **I did not verify the result document's round-4 prose line by line** —
+   only the mutation table, the baseline table, and the § 9.7 self-report,
+   which are what I could independently reproduce.
+
+---
+
+## Verdict
+
+**PASS. This row merges.**
+
+The round-3 blocker is closed, and closed by a test rather than by a promise:
+deleting the bullet is red, and adding a fifth ignored directory with the
+equality pin moved with it — the case the equality pin alone would miss — is
+red too. Both behaviour changes in `tests/run` are correct and bounded: the
+relative refusal is a decision with a banner that explains itself and costs
+nothing in this repository, and `-ef` accepts exactly the spellings the
+filesystem folds, refusing them on a case-sensitive volume, which I exercised
+rather than reasoned about. MC1 kills exactly one test and it is the new one.
+All three fixes from `df8d536` are genuinely closed, each with a paired revert
+that turns the attack green again. The four open green mutations are each open
+for a reason that is true. The final tree is byte-identical to git's own
+objects for `f8bc100`, checked against `git ls-tree` and `git hash-object`
+rather than against anything the row produced. The merge is clean and moves the
+failure count nowhere: 4 across 3, the same four by name, on `main`, on the
+tip, and on the merge.
+
+**Fix, or file (3 items) — none blocking:**
+
+- **The new pin is satisfied by a substring, not by a bullet, and its name says
+  otherwise.** `assertIn(name, section)` passes for a name that appears
+  anywhere in the section: `.claudex` needs no bullet at all (the `.claude`
+  bullet's control sentence already contains the string, and now says the
+  opposite of the truth), `.md` needs none either, and a bullet that names a
+  directory and describes it backwards is green. Either say so in the
+  docstring — the way the sibling pin now does — or require the name to open a
+  `- **` bullet inside the section.
+- **`test_a_foreign_perry_project_refuses_the_run` asserts the generic
+  `refusing to run`, not its banner.** With two banners now, inverting the
+  `case` arms leaves it green (MS1). Its tightened sibling reads the banner;
+  this one should too.
+- **`MS2` — the pin can be tripped red by a help line.** An `echo` inside the
+  refusal's own message that mentions `export PERRY_PROJECT` is not a comment,
+  so `_implemented` reads "both mechanisms" and both pin tests fail with a
+  message that is false about a change that ships neither. Fails red, so it is
+  a nuisance; anchoring the export pattern to a line that is not inside an
+  `echo`, or simply noting it, would close it.
+
+**One line worth adding to the row, not a defect:** round 3's § 7 item 7 and
+the row's own "the skip path is reasoned, not exercised" can both be struck —
+the skip fires and the behaviour is correct on a genuinely case-sensitive
+filesystem, measured here.
+
+*Every experiment ran on copies, in my own detached worktrees, or on a disk
+image I created. The live checkout was never written to and is at `4716e39`
+with an empty `git status`. `perry/BOARD.md` and `perry/tasks.jsonl` untouched;
+no write-side Perry tool was run against the project or any worktree of it;
+`perry-conform declare` and `perry-tasks render` were never invoked; no
+identifiers minted.*

+# TASK-249 — bash tests/run WRITES PERRY STATE INTO THE REPOSITORY IT RUNS IN — four files, via an intake-sweep discharging a real board row
+
+> Consolidated from the board row 2026-08-30. The row's own fields are the
+> acceptance criteria; this file is where a V4 reviewer reads them.
+
+## Why this row exists
+
+Proved by a controlled experiment by the TASK-050 round 11 agent, 2026-08-30, and independently the cause of a stray event the PMO caught in TASK-241's merge an hour earlier. Running the suite modifies .perry/events.jsonl, perry/BOARD.md, perry/intake.jsonl and perry/journal/<today>.md in whatever repository it executes in, by running an intake-sweep that discharges one board row. The experiment: restore the four files, run the suite, and the same four move again. THE SWEEP IS IDEMPOTENT, WHICH IS WHY A SECOND RUN LOOKS CLEAN — that is why nobody noticed. It matters beyond tidiness: two of the suite's three standing failures are data-dependent on board state, so the suite perturbs the very state its own results depend on. It is also how a stray intake-sweep event with actor 'agent' ended up committed on a coding branch and was caught only because an append-only file conflicted at merge; a fast-forward would have carried it into main silently.
+
+## Deliverable
+
+—
+
+## Verification — V4
+
+V4
+
+## Out of scope
+
+—
+
+## Where to start
+
+Startable. Start from TASK-050 round 11's result, which carries the controlled experiment, and from the TASK-241 merge, where the stray event surfaced. The idempotence is the reason this survived: the first run in a fresh clone moves four files, and every run after it looks clean, so the natural way to check — run it twice and diff — reports nothing. Restore the four files first, then run once.

+# TASK-249 — V4 review, round 1
+
+**FAIL.** The work itself is good and I could not break the fix: the call site is
+correctly identified, the guard fires on every exit path I could reach, its own
+test is real, its control can fail, and M8 reproduces exactly. The row fails on
+its **§ 5 baseline**, which is wrong in a way that matters more here than
+anywhere else: the result publishes a corrected number for `main`'s fork point,
+uses it to conclude that "the PMO measured a working tree with uncommitted board
+edits", and the correction does not survive a clean `git archive` of that commit.
+A row whose subject is *the suite corrupting its own measurements* cannot ship a
+mis-stated measurement that blames another agent's correct one.
+
+Everything below was done on **copies** (`git archive` of `49d83fc` / `1f7a13f`
+into `scratchpad/rj249/rj249-*`), never in the reviewed worktree. Nothing was
+written into `/Users/bytedance/proj/Perry` or into
+`scratchpad/review-249`, and no write-side Perry tool was run against either.
+The four files in `scratchpad/review-249` were hashed at 09:39 and are
+byte-identical now:

+    cd scratchpad/rj249/rj249-base && bash tests/run      # 09:43-09:48
+
+Output (`rj249-base.log`):
+
+    ✗ test_diagnose.py
+      FAIL: test_the_queue_register_reconciles_with_the_queue_on_this_repository

+    103 modules · 3098 tests · 288.8s · 8 workers
+    ✗ 3 module(s) red
+
+**Four failing tests in three red modules.** Deterministic — `test_diagnose`
+re-run alone on the same archive is `Ran 141 tests … FAILED (failures=2)`.
+
+The same shape on the branch (`git archive 1f7a13f`, full `bash tests/run`,
+09:48-09:59, `rj249-branch.log`):
+
+    104 modules · 3111 tests · 652.6s · 8 workers
+    ✗ 3 module(s) red        ← same four failing tests, by name
+      ✓ nothing under …/rj249-branch moved
+
+So **the fork point and the branch are both 4 failing tests / 3 red modules.**
+The branch adds no failure — that half of the claim is true and I confirm it.
+But the "3" is the runner's own `✗ 3 module(s) red` line read as a failure
+count, and the consequences are three:
+
+1. **The named list is short one failure.** § 5 names
+   `test_diagnose § test_perry_itself_passes_its_own_id_checks`,
+   `test_heading_title § test_none_of_them_contains_its_own_id` and
+   `test_kr_progress_provenance § …` as "the same three failures, by name".
+   `test_diagnose § test_the_queue_register_reconciles_with_the_queue_on_this_repository`
+   is missing. It is one of the two board-data-dependent tests this row's own
+   summary is about ("two of the suite's three standing failures are
+   data-dependent on board state") — the single most relevant failure in the
+   suite to this row, dropped from the row's own baseline.
+2. **The PMO's 4 is correct**, and it was measured on a tree that behaved
+   exactly like a clean archive. The charge that it "measured a working tree
+   with uncommitted board edits — which is this row's own point" is unfounded
+   and should be withdrawn. It is also contradicted by the project's own filed
+   intake row of 2026-08-29, which already records "the `tests/run` baseline is
+   **4 failures on a clean archive copy** and 5 on a worktree carrying today's
+   intake rows".
+3. It is the one number in the document nobody downstream can re-derive from the
+   document, and it was used to discredit a measurement rather than to describe
+   this branch.
+
+**Which baseline is right: the PMO's.** `49d83fc` is 103 modules / 3098 tests /
+**4 failing tests** (3 red modules) on a clean `git archive`, at 08:48 and again
+at 09:43. This branch is 104 / 3111 / **4 failing tests** (3 red modules) — the
+same four by name, `+1 module / +13 tests` being exactly `tests/test_tree_guard.py`.
+No number here was measured through the defect this row closes.
+
+## Second defect — the ignore-list pin does not pin the list that matters most
+
+§ 6.3 and `tree_guard.py`'s own comment claim the ignore list is pinned so that
+"growing it — the cheapest way to make a red run green — has to change a line a
+reviewer looks at". There are **three** ignore lists and the pin covers two:
+
+    IGNORE_DIRS      pinned by test_the_ignore_list_is_the_documented_one
+    IGNORE_SUFFIXES  pinned by the same test
+    IGNORE_NAMES     NOT pinned by anything
+
+`IGNORE_NAMES` is the list that takes **file names**, i.e. the shape that can
+name a state file. Mutation on a copy of the branch:
+
+    IGNORE_NAMES = frozenset({".DS_Store", "events.jsonl", "intake.jsonl"})
+    python3 -m unittest discover -s tests -p test_tree_guard.py
+    → Ran 13 tests in 66.557s
+      OK
+
+The whole guard module stays green while the guard is made structurally blind to
+`.perry/events.jsonl` and `perry/intake.jsonl` — two of the four files this row
+exists to protect. (`BOARD.md` is incidentally covered, because
+`TestThePlantedWrite` asserts the literal string `M perry/BOARD.md`; every other
+state filename is not.) One line added to the existing test closes it.
+
+---
+
+## checked
+
+**The call site.** `tests/test_task_writer.py:1359` at `49d83fc` is correct, and
+the mechanism is exactly as described: `bin/perry-task:7101-7102` resolves
+`--root` → `$PERRY_PROJECT` → cwd, and `tests/run:31` cds to `$ROOT`.
+
+**Claim 1 — the four md5s move before the fix and not after.** Own measurement,
+two scratch copies, one intake row discharged in each (`Outcome` set to prose;
+no identifier minted), the single test run alone:
+
+    python3 -m unittest discover -s tests -p test_task_writer.py \
+            -k test_every_accepted_command_runs_and_is_advertised
+

+|---|---|---|---|---|

+
+The test was **green both times**. The event that landed, from my run:
+
+    {"ts": "2026-08-30T09:42:18+08:00", "event": "intake-sweep", "id": "",
+     "title": "", "count": 1, "actor": "agent", "from": "intake", "to": "journal"}
+
+My `perry/BOARD.md` and `perry/intake.jsonl` after-hashes are **identical to the
+result's table** (`6352b630…`, `53bccb3a…`), which is a good independent
+corroboration of that measurement.
+
+**One writer among 29.** Own sweep, each name run bare against a fresh untar of a
+pristine `49d83fc` + one discharged row, whole tree hashed after
+(`rj249-sweep29b.sh`):
+
+    28 × "clean <name> rc=1"
+    WRITER intake-sweep rc=0
+    ... second sweep on the same tree: refused, IDEMPOTENT: second sweep moved nothing
+
+**Enumerating every in-repo-root invocation — 106 not reproduced; the shape is.**
+I instrumented `bin/perry-task` in a pre-fix copy at *process start* (so
+argparse-refusals are logged too), recording argv, cwd, `$PERRY_PROJECT`, the
+root that would be resolved and the process chain, and ran one full
+`bash tests/run`:
+
+    total perry-task invocations during one run: 1979
+    by root-resolution source: {'--root': 1891, 'cwd': 88}
+    resolved to the REPO ROOT: 110   ({'cwd': 88, '--root': 22})
+
+So **88 un-rooted invocations against the live checkout** (plus 22 that pass
+`--root <the repo root>` deliberately). Breakdown of the 88: `list --json` ×22,
+`list --all --json` ×16, `events --json` ×16, `--help` ×3, `list` ×2, and the
+29-name loop plus `nonesuch`. Exactly one of them writes: `intake-sweep`.
+I could not land on 106 — it is a tree-and-revision-dependent number the result
+quotes unqualified — but "many reads, exactly one writer" is confirmed, and the
+one writer is the one named.
+
+**Verdict on the 105 (87) reads against the live checkout: acceptable, with one
+qualification worth a board row.** They cannot mutate, and several read this
+repository's board on purpose. But the result's justification (§ 6.5, "reading
+this repository's own board") assumes `$PERRY_PROJECT` is unset. Root resolution
+is `--root` → `$PERRY_PROJECT` → cwd, so with that variable exported — a live
+hazard this session's own dispatch commit names — those 88 calls read *someone
+else's* project, and the assertions built on them are then about the wrong tree.
+That is a wrong-answer risk, not a corruption risk, so it is a finding rather
+than a blocker. (See D5 below for the pre-fix corruption version of it.)
+
+**The EXIT trap fires on the abort paths it claims.** Both tested on a branch
+copy with a write planted inside `bin/perry-lint` so that step 1 itself dirties
+the tree:
+
+- `--lint` early exit (line 83): guard ran, `+ rj249-lint-plant.txt   (created)`,
+  `✗ failures above`, `rc=1`.
+- a bare `false` under `set -e` inserted after step 1: same guard output, same
+  red banner, `rc=1`.
+- a failing step 2 followed by step 3's `[ "$fail" = 0 ] && echo …`: I expected
+  an errexit abort there and there is none — both `49d83fc` and `1f7a13f` reach
+  step 4. Not a hole; recording it because it is the obvious one to suspect.
+
+**Wiring mutations (my own, on top of the author's seven).** Each applied to a
+copy, `TestThePlantedWrite` re-run:
+
+    MR1 the EXIT trap is not installed            RED
+    MR3 verify never runs (the trap calls true)   RED
+    MR4 a moved tree does not set fail            RED
+
+**Every guard in `tree_guard.py`, not only the seven.** Applied to a copy,
+`TestTheManifest` + `TestTheCLI` re-run:
+
+    A  grow IGNORE_NAMES                          GREEN  ← survives; see above
+    B  grow IGNORE_DIRS                           RED
+    C  shrink IGNORE_SUFFIXES                     RED
+    D  directories are not recorded               RED
+    E  symlink target recorded as a constant      RED
+    F  verify always exits 0                      RED
+    G  the failure drops the perry-task hint      RED
+    H  a bad invocation exits 1, not 2            RED
+
+**Claim 2 — the guard's test is real, and the control can fail.**
+`python3 -m unittest discover -s tests -p test_tree_guard.py -v` → 13 tests, OK.
+It does copy the repo, plant into the copy, and drive the real
+`bash tests/run --only …`. Two independent falsifications:
+
+- Control can fail: I made `CONTROL` write one file into its own root instead of
+  only into a temp dir. `test_a_module_that_stays_in_a_temp_root_is_green` →
+  `FAILED (failures=1)`. It is not vacuous.
+- Mechanism can fail: I replaced `python3 tests/parallel "$only"` with `true` so
+  `--only` runs nothing. `test_the_same_run_is_green_when_the_guard_is_neutered`
+  → RED with `"planted by TASK-249's guard test" not found in …`. A broken
+  `--only` cannot masquerade as a working guard.
+
+Timing note: 13 tests took 66-102s here, not the claimed 5.1s. My machine was
+running three other suites; I did not get a quiet re-measurement, so I am not
+calling the 5.1s wrong — only unverified. Guard cost is right: 0.19s warm /
+0.92s cold to hash 811 entries, `bash tests/run --lint` 0.50s end to end.
+
+**Claim 3 — M8 reproduces exactly.** Branch copy, `--root` taken back off the
+call site, one intake row discharged:
+
+    bash tests/run --only test_task_writer
+
+    1 modules · 281 tests · 178.2s · 8 workers
+    ✓ all green                                    ← the module passed
+    tests/tree_guard.py: THE SUITE WROTE INTO THE TREE IT RAN IN — …
+      M .perry/events.jsonl   (changed)
+      M perry/BOARD.md   (changed)
+      M perry/intake.jsonl   (changed)
+      M perry/journal/2026-08/2026-08-30.md   (changed)
+    ✗ failures above                               rc=1
+
+Exactly the four files, from a green module. This is the claim that matters and
+it holds.
+
+**The guard is unnecessary on this branch, and I proved it rather than assumed
+it.** Full `bash tests/run` on a byte-identical copy of `1f7a13f`: the four files
+were unchanged before and after, and step 0 printed
+`✓ nothing under …/rj249-branch moved`. The same full run at `49d83fc` also left
+them unchanged — because that archive has no discharged intake row for the sweep
+to find, which is the idempotence, measured.
+
+**Claim 4 — I found four more ways to defeat the guard.** Each is one planted
+module run through the real `bash tests/run --only …` on a fresh branch copy;
+each run came back `✓ all green` while the checkout had genuinely moved:
+
+- **D1 · file mode.** `os.chmod(ROOT/"bin"/"perry-lint", 0o600)` — the manifest
+  hashes bytes only. `git status` reports a mode change; the guard does not.
+  This project ships executables in `bin/` and `templates/*/bin/`.
+- **D2 · any directory *named* like a cache, at any depth.** `perry/node_modules/BOARD.md`,
+  `.perry/__pycache__/BOARD.md`, `perry/.git/BOARD.md` all invisible —
+  `IGNORE_DIRS` is matched on the basename anywhere in the walk, not on a
+  top-level path.
+- **D3 · any ignored suffix or name, anywhere.** `perry/BOARD.pyc` and
+  `perry/.DS_Store` invisible. Combined with the unpinned `IGNORE_NAMES` above,
+  this is the same weakness twice.
+- **D4/D5 · anything outside `$ROOT` — the one that matters here.** The guard
+  hashes `$ROOT` and only `$ROOT`. Demonstrated with the real defect: branch
+  copy, `--root` reverted, `PERRY_PROJECT` pointed at a *second* checkout:
+
+      PERRY_PROJECT=…/rj249-victim bash tests/run --only test_task_writer
+
+      0. tree guard — the tree the suite started in is the tree it ends in
+        ✓ nothing under …/rj249-m8env moved          ← the runner tree, clean
+
+      victim  .perry/events.jsonl   19370b5e… → 3a9d18c9…
+      victim  perry/BOARD.md        bd51703b… → 6352b630…
+      victim  perry/intake.jsonl    b73d6022… → 53bccb3a…
+      victim  perry/journal/…-30.md b9a6eaed… → f535a39e…
+
+  All four files of this row moved in a *different* Perry checkout and the guard
+  said the tree was clean. This repository runs several worktrees at once and
+  `$PERRY_PROJECT` is on this session's own hazard list, so it is not
+  hypothetical. The `--root` fix immunises this call site (`--root` beats
+  `$PERRY_PROJECT`, `bin/perry-task:7101`), so it is a limitation of the guard,
+  not a live defect — but it belongs in `tree_guard.py`'s "what it does NOT
+  catch" list beside the three that are already there.
+
+**The fixture-was-unreachable argument: the author is right.** The pre-fix call
+site is
+
+    r = subprocess.run(
+        ["python3", str(PERRY_HOME / "bin" / "perry-task"), name],
+        capture_output=True, text=True)
+
+— a bare `subprocess.run` on a hand-built argv. It constructs no `Project()`,
+touches no fixture, and passes through no helper that could have refused an
+in-repo root. A fixture-side guard would have protected exactly the call sites
+that were already passing `--root` and would have been structurally incapable of
+seeing this one. Taking the guard was the right call, and taking the call-site
+fix as well was right too: the guard only reddens where the sweep has a row to
+find, so without the fix the defect is live on every fresh clone and merely
+invisible on an already-swept tree. One correction to the framing: the committed
+`perry/evidence/2026-08/TASK-249-spec.md` (from `f92aed1` on `main`; it is not on
+this branch) contains no "two shapes" — its Deliverable is `—`, and neither the
+board row nor the dispatch commit names a fixture option. "The spec offered two
+shapes" is not checkable against anything in the repository.
+
+## not-checked
+
+- The author's harness `task249_tree_guard_mutation_harness.py` is scratch and
+  not committed, so I could not re-run their seven mutations as written. I ran
+  eleven of my own instead (A-H, MR1/MR3/MR4), which cover the same surface and
+  one they did not.
+- The 5.1s figure for `test_tree_guard.py` — the machine never went quiet.
+- The `106` figure — see above; I measured 88 un-rooted / 110 total against the
+  repo root and cannot reconstruct which tree gives 106.
+- Whether `test_the_queue_register_reconciles_with_the_queue_on_this_repository`
+  and `test_perry_itself_passes_its_own_id_checks` are themselves correct. They
+  are pre-existing and not this row's.
+- The flake (`test_host_support § test_concurrent_mixed_registers_do_not_exceed_global_cap`)
+  did not fire in either of my full runs. Recording it as flaky rather than
+  filing it was the right call; I have nothing to add.
+
+## what would clear this
+
+1. Correct § 5: the fork point and the branch are both **4 failing tests / 3 red
+   modules**, name all four, withdraw the "the PMO measured a working tree"
+   inference, and say plainly that the branch adds no failure — which is true.
+2. Pin `IGNORE_NAMES` in `test_the_ignore_list_is_the_documented_one`.
+3. Add "anything outside `$ROOT` — including another checkout, when
+   `$PERRY_PROJECT` is set" and "file mode" to `tree_guard.py`'s "what it does
+   NOT catch" list, and to § 6.
+
+Nothing in 1-3 touches the fix or the guard, both of which I tried hard to break
+and could not.

+# Hand-off to the `goals` lane — three things DESIGN-013 and ADR-010 put in your court
+
+> From: `work` lane (PMO), 2026-08-29, at `8abd30d` + the DESIGN-013 § 9 amendment.
+> The `work` lane does not write `OKR.md` or `phase/`. Everything below is a
+> `goals`-lane write, which is why it is a hand-off and not a task row.
+
+DESIGN-013 was locked and ADR-010 minted on 2026-08-29. Between them they change
+three things the `goals` lane owns. None of the three is urgent this hour; all
+three are wrong to leave undecided while phase 003 is still running.
+
+## 1. `P003-O2-KR3` becomes unmeetable, and its only row is mooted
+
+The KR, from `phase/003-storage-code.md:141`:
+
+> `P003-O2-KR3` — `BOARD.md`'s two truth models are marked in the file, so a
+> reader can tell which sections are projected from a store and which are still
+> canonical markdown (baseline: nothing marks the boundary — TASK-199) ·
+> target: **boundary marked**
+
+`ADR-010` decides `BOARD.md` stops existing. A boundary cannot be marked in a
+file that is gone, and `TASK-199` — this KR's only row — has nothing left to do.
+
+**What is needed:** a decision, and it is not the `work` lane's to make. The
+options as they look from here:
+
+- **(a) Restate the KR** as something `ADR-010` can satisfy — e.g. *the render
+  distinguishes what is projected from what is canonical*, which is the same
+  reader-facing property the KR was actually buying, on a surface that will
+  exist. `TASK-199` is then re-scoped rather than dropped.
+- **(b) Drop the KR and drop `TASK-199`**, and record that phase 003 closes with
+  one KR withdrawn by a decision made during the phase. Honest, and it makes the
+  phase's score mean what it says.
+- **(c) Keep both and mark the boundary anyway**, on a file that is scheduled for
+  deletion. Cheapest to do and hardest to defend.
+
+**Do not do (b) silently.** Dropping a KR changes what phase 003's Definition of
+Done means, and the phase is live. `USER-907` is filed on the board asking the
+user directly; the `goals` lane should read the answer there rather than choose.
+
+`TASK-199` has been left `not_started` and untouched. The `work` lane will not
+drop it — dropping the row is the visible half of dropping the KR, and doing the
+visible half first would make the record say the KR failed rather than that it
+was withdrawn.
+
+## 2. Where `TASK-235`, `TASK-236` and `TASK-237` belong
+
+The three rows generated from DESIGN-013 are on the board as P1, `main` track,
+declared unlinked:
+
+| Row | What it does |
+|---|---|
+| `TASK-235` | `DECISIONS.md` deleted; `perry-decide list` is the surface |
+| `TASK-236` | `OKR.md` drops its KR tables; `perry-goals` renders them |
+| `TASK-237` | `BOARD.md` deleted; the board is what a command prints |
+
+**The `work` lane's read: these are the spine of the NEXT phase, not patches to
+this one.** Phase 003's Definition of Done is the six declared stores and the
+markdown readers that still read as truth; DESIGN-013 removes the documents those
+readers point at, which is a different objective and a larger one. Putting them
+inside phase 003 would expand a running phase's scope, which is the thing a phase
+exists to prevent.
+
+The user asked on 2026-08-29 whether they should be P0 and immediate. The `work`
+lane's answer was no, on three measured grounds — P0 means "must finish this
+period" and would displace the phase's own Must-Haves; priority cannot compress
+`TASK-237`'s gate on `TASK-236`'s written read-surface report; and four agents
+were in flight on the affected surface. That answer is the `work` lane's on
+sequencing. **Which phase they belong to is yours.**
+
+## 3. `P003-O2-KR1`'s target is still the wrong number
+
+Filed on the board twice and named by two consecutive V4 reviewers, still open:
+
+> `P003-O2-KR1` reads target 0 in `phase/003-storage-code.md` while the literal
+> count is >= 7 — six `kind:setting` reads at `perry-state:126-135` plus
+> `perry-conform:304`. The honest number is **"0 track-register readings"**, and
+> it must become an EDIT to the phase file.
+
+This is a `goals`-lane write and has been waiting since 2026-08-29 morning. It is
+listed here because `TASK-157` is in flight against the same phase file and
+`TASK-233` was opened for the readers the wrong number refers to — the number
+should be corrected before either lands, so the reviewer of those rows grades
+against a target that means something.
+
+## What the `work` lane did NOT do, deliberately
+
+- Did not edit `phase/003-storage-code.md` for item 3, or any KR for item 1.
+- Did not drop `TASK-199`.
+- Did not link `TASK-235`/`236`/`237` to any KR. They are declared unlinked
+  rather than guessed into one, per `reference/okr-linkage.md § The one rule`.
+
+## References
+
+- `perry/design/DESIGN-013-one-place-per-fact.md` — locked 2026-08-29, § 9 carries
+  one post-lock amendment.
+- `perry/decisions/ADR-010-the-board-is-a-render-not-a-file.md`
+- `perry/evidence/2026-08/TASK-157-spec.md` — the phase KR duplication, measured.

+# Handoff — overnight run, 2026-08-29
+
+> Written by the PMO for the user's return. Everything below is on a branch;
+> **nothing has been merged to `main`.** The only writes to `main` are PMO
+> records: `BOARD.md`, `journal/2026-08/2026-08-29.md`, and files under

+
+## The one-line version
+
+Eight rows closed at V3 with evidence and mutation proof; three rows built and
+sent to a fresh V4 reviewer, **three of which came back FAIL and were rebuilt** —
+two of those FAILs were regressions the fix itself introduced, and both are
+fixed and reproduced against the fix.
+
+## Closed, V3, evidence written
+
+| Row | What | KR |
+|---|---|---|
+| `TASK-209` | the store-drift census covers six stores, not two | **`P003-O1-KR2` at target** |
+| `TASK-229` | six store removals, six `unchecked` verdicts, measured | **`P003-O1-KR3` at target** |
+| `TASK-228` | `attribution`'s three buckets are disjoint | — |
+| `TASK-211` | the dispatch limiter says what it cannot know | — |
+| `TASK-227` | a declaration of drift is validated at writer and linter | — |
+| `TASK-215` | the writer stamps `> Last updated:`, because a render is not a write | `P003-O2-KR3` |
+| `TASK-213` | four readers, one blank-cell rule — `Depends on: 待定` was a real dependency id | — |
+| `TASK-216` | the foreign-write guard reads the summary tables too | — |
+
+`TASK-228` is the one that had already cost something: `unlinked` counted
+declared rows too, and this session read that number off the payload and told
+the user 52 rows owed an attribution answer when the true never-asked count was
+**0**. The correction is in this run's own transcript.
+
+## Built, under review, NOT merged
+
+| Row | Branch | State |
+|---|---|---|
+| `TASK-095` | `coding/2026-08-29-overnight-batch` @ `d77e84d` | **rounds 1–5 all FAILED — blocked on `USER-905`** |
+| `TASK-203` | `coding/task-203-register-stores` @ `d075698` | **rounds 1–3 all FAILED — blocked on `USER-906`** |
+| `TASK-050` | `coding/task-050-header-harness` @ `c67e5a4` | **round 7 FAILED — blocked on `USER-904`** |
+
+## What the reviewers caught, because it is the most useful part
+
+**`TASK-095` round 1 — FAIL.** `declared_tracks` fell back to the markdown in
+three states where the store *exists*. Fixed by splitting the four situations.
+
+**`TASK-095` round 3 — FAIL, and mine again.** Round 3 returned
+`[DEFAULT_TRACK], source: "store"` for *any* validating store with no track
+record, regardless of what the table declares. On a project whose `## Tracks`
+declares `main` and `intake` while the store carries settings only — real drift,
+`perry-lint` reports two rows — it reported one track, no warning, allowed the
+write, and then refused `add --track intake` with a message pointing at the very
+table that declares it on line 14. **Worse than `45a355d` and worse than round
+2.** Round 4 adds a fourth source value, `store-default`, and distinguishes the
+two situations: a store that declares nothing beside a table that also declares
+nothing is a complete answer and stays silent; the same store beside a
+two-track table is drift, warns, and refuses the write with an accurate message.
+
+**`TASK-095` round 2 — FAIL, and the FAIL was mine.** The round 1 fix classified
+`no-track-record` as unusable and hung a permanent write refusal on it.
+`schema/state-schema.json` line 5 (DESIGN-003, **locked**) defines that state as
+valid and determined. Three of this repo's own fixtures have no `## Tracks`
+section, so every write on them was refused — pointing the user at two commands
+that report the store as `drift_count: 0, byte_identical: true`. Round 3 makes a
+trackless store an *answer*.
+
+**`TASK-203` round 1 — FAIL, two blocking, both regressions the row created.**
+The renumbering exemption was keyed on the command name when the hazard is
+whether rows moved, so a hand-deleted intake row plus any ordinary write
+recorded a live request as discharged, permanently, with lint reporting clean —
+**and my own commit message described that defect and claimed to have prevented
+it.** Second: one clause in a gate truncated a present three-record store to
+zero bytes on an unrelated `add`. Round 2 fixes both, and both are reproduced
+against the fix.
+
+**`TASK-050` round 5 — FAIL.** The harness was a regression corpus, not a
+harness; the reviewer planted nine readers and five escaped, including one
+appended to `viewer/parsers.py` that reproduced the spec's own column-loss
+defect with both guards silent. Round 6 replaces the regex with an AST walk.
+
+**One thing that will look wrong at a glance.** `main`'s `BOARD.md` still reads
+`> Last updated: 2026-08-16`. That is correct: `TASK-215`'s fix is on a branch,
+so `main` is still running the old writer. It corrects itself on the first write
+after the merge.
+
+**`TASK-203` round 2 — FAIL, three blocking, all the same shape.** `(request,
+arrived)` is not a unique key: two intake rows with the same Request on the same
+day is the *ordinary duplicate case*, and every intake row gets today's date, so
+identity collapses to the Request string — round 1's exact harm, reproduced at
+this commit. The store-truncation gate covers `has_section` only, but the
+derivation also returns `[]` for a prose section and a foreign header, so a
+three-record store still goes to **zero bytes** three other ways. And the merge
+is *still* untested: my `current = None` mutation goes red on a `TypeError`
+before the merge runs, while the honest `current = []` is green across all 2808
+tests, because the flag my tests assert is re-derived from the `Outcome` cell.
+
+**`TASK-203` round 3 fixes all three blocking findings** — a non-unique
+identity is refused as no join at all; `readable_as_register` asks
+`perry_store`'s own shape function so all four board shapes are covered for all
+three registers, not the one that had been reported; and the merge finally has
+a test that asserts a fact the board cannot re-derive, so `current = []` — green
+across 2808 tests at round 2 — is red. **Two of my own tests in that round were
+green for the wrong reason and mutation caught both**: the duplicate-Request
+test followed with an `intake`, which trips the ordinary positional check first,
+so it passed with the uniqueness guard deleted; and the prose fixture ate the
+board, so the write refused for an unrelated reason.
+
+**`TASK-216` is the one row tonight where the discipline held from the start.**
+I measured the three scan configurations *before* touching anything, found the
+row's own predicted number was wrong (2, not 3 — the true positive had already
+been corrected on 2026-08-28), said so, and reached it by mutation instead. The
+decisive mutation is the fourth: with the shipped verb list and the real defect
+restored, the guard reports **nothing** — it was blind to its own subject.
+
+**The pattern, and it is the most important thing here.** `TASK-095` has failed three rounds and I
+caused two of them, `TASK-203` has failed two and I caused both, and `TASK-050`
+has failed seven. **Three independent reviewers found the same thing three times
+tonight: I fix the reported instance, not the category.** Round 1 of `TASK-095`
+collapsed four `None`s; round 2 collapsed `no-track-record`; round 3 collapsed
+the two default cases. `TASK-203` keyed on a command name, then on a non-unique
+tuple. Each fix was correct about the case in front of it and blind to the
+sibling case one step away.
+
+The rounds are converging — round 4 of `TASK-095` and round 6 of `TASK-050` are
+both materially better than what preceded them, and every reviewer said so — but
+the *method* that produced them is the thing to look at, not the individual
+diffs. My working hypothesis is that enumerating the state space **before**
+writing the fix, the way these reviewers do, is what I have been skipping.
+
+## `TASK-095` is now a decision too — `USER-905`
+
+Five rounds, three of them my regressions, **every one the same shape one step
+to the left**: round 1 collapsed four `None`s; round 2 collapsed
+`no-track-record`; round 3 collapsed the two default cases; round 4 filtered on
+the *name* `main` instead of on whether the table *declared* it; round 5
+compares names over records, so a record that **contradicts** a declared row
+counts as carrying it.
+
+Round 5 genuinely fixed round 4's defect and closed the mirror asymmetry — the
+localized `## 轨道` path now matches the English one at every state. It failed on
+the next state over.
+
+**The reviewer states the decision cleanly.** Two principles, each defensible
+applied once; round 5 applies one to the synthesised `main` and the other to the
+recorded `main`:
+
+- **(A)** *a declared row the register contradicts is drift* → the trackless
+  case and the contradicting-record case both warn. `perry-lint` already
+  computes exactly this.
+- **(B)** *the store is truth, the table is a stale projection* → both are
+  silent, because the register answered in each.
+
+**And a second, more urgent decision that is my doing.** I widened the write
+refusal from `store-default` to `store`. Three ordinary hand-edit workflows that
+wrote at `45a355d` **and** at round 4 are now hard-blocked — and on one of them
+`perry-config write --from-file`, the only command either refusal message names,
+**exits 1**. The block cannot be cleared by the remedy it points at. Options:
+revert to round 4's width, downgrade to a warning, or fix `perry-config`.
+
+My recommendation: **(A)**, because `perry-lint` already owns that rule and
+re-deriving it differently has been the root cause for three rounds; plus revert
+the width until the remedy works. Everything is on an unmerged branch, so
+nothing is harmed in production.
+
+## `TASK-203` is the third decision — `USER-906`
+
+Three rounds, all mine, **all ending in the same defect: an ordinary command
+silently truncates a canonical store.**
+
+Round 3 fixed a great deal — all four mutations exact, the merge test finally red
+under the *honest* deletion, a 60-cell matrix finding no shape-visible
+truncation, crash recovery at all three rename boundaries, the localized board
+correct. Then: **the gate is read at a moment the command controls.**
+`cmd_add`'s queue branch calls `ensure_section("Intake")` *before* `commit()`
+asks the gate, so the gate sees a freshly created, readable, **empty** table and
+writes zero bytes. A 291-byte three-record store → 0, `rc 0`, byte-identical on
+base, `perry-lint` reporting *"0 row(s) drifted"*.
+
+That is round 1's blocking finding word for word. Round 2 closed it for the
+project-mode track and never asked the queue-mode track — the mode `## Intake`
+exists for. **My shipped regression test goes red on `--track ops` with nothing
+else changed.**
+
+The choice is in `USER-906`. My recommendation is **(B)**: make it structurally
+impossible — *an ordinary write may never shrink a canonical store*; only an
+explicit removal command may reduce the record count, and a derivation producing
+fewer records than the store holds is a refusal. **One invariant covering every
+door found in three rounds** — the command name, the non-unique tuple, the four
+section shapes, and now the `ensure_section` ordering — instead of a fourth
+predicate. Option **(C)**, reverting the row, is on the table and deserves a real
+answer: before it, `intake.jsonl` did not exist and could not be wrong.
+
+This one affects the phase directly: `TASK-203` is the **only** row under
+`P003-O1-KR1`, and DoD Must-Have 2 names `intake.jsonl` and `asks.jsonl`
+explicitly.
+
+## Three things that need you
+
+1. **`P003-O2-KR1` cannot honestly read 0.** The KR counts *"call sites in
+   `bin/` that read a projected markdown file as truth while its store
+   exists"*. Six `kind: setting` reads at `bin/perry-state:126-135` and
+   `Conformance gate` at `bin/perry-conform:304` are the same category and are
+   not excluded readers. The honest number is **"0 track-register readings"**.
+   Scoring the KR at 0 would be a measurement error. Filed to `## Intake`.
+2. **`TASK-050` has failed SEVEN rounds and is now blocked on you — `USER-904`.**
+   Round 7 proved the AST walk's gate is still an allowlist of variable names:
+   of 829 mapping constructs, 59 classify as row-cell sources and 35 of those
+   are the bare name `header`. **Four live header resolutions revert to the
+   historical defect with the whole suite green**, and `viewer/parsers.py:1827`
+   silently drops a KR when reverted. In the other direction the check now
+   reports *correct* code — six of eight legitimate shapes, including the exact
+   latent risk round 5 recorded. Blind to four of the tree's own header
+   resolutions and loud about a keyword tokenizer: both failure modes the spec
+   names, in one artefact.
+
+   The choice, in `USER-904`, with my recommendation:
+   **(A)** round 8, same shape — the record says this is the fourth time that
+   moves the defect rather than closing it;
+   **(B)** invert the burden — flag every case-folding map and make the ~30
+   legitimate value normalizers carry a one-line opt-out;
+   **(C) recommended** — make it structurally impossible: one `header_index()`
+   owns header folding and the guard becomes a one-symbol surface instead of a
+   shape, which is the move ADR-007 already made for stores;
+   **(D)** accept it as advisory, close at a lower rung, document the limit.
+3. **The merges, and a structural mistake I made.** Three branches, none
+   merged. I stacked `TASK-095`'s V4 work onto the same branch as five closed
+   V3 rows, so `coding/2026-08-29-overnight-batch` cannot be merged without
+   merging code that is still under review. The right sequence:
+
+   - `TASK-095` round 4 PASSes → merge the batch whole (it carries `TASK-228`,
+     `TASK-211`, `TASK-227`, `TASK-215`, `TASK-213` and `TASK-095` together).
+   - `TASK-095` round 4 FAILs → the six V3 rows are still good and their commits
+     are separable; either cherry-pick them or fix `TASK-095` and re-review.
+
+   `main` is red before any of this, so "merge when green" is not available as
+   a rule — the bar I used instead is "adds no failure under either runner",
+   measured on both for every branch.
+
+## `main` was already red
+
+3 modules / 5 failures under `bash tests/run`; 8 failures / 4 modules under
+`python3 -m unittest discover -s tests`. The extra 3 are `test_risks_store`'s
+`assertIs` checks — a module-double-import artifact of `discover` mode,
+observed independently by three reviewers. **None of tonight's work adds a
+failure under either runner.** The `test_diagnose` red is 5 dangling ids
+introduced by the phase-003 *planning documents*, which is `TASK-179`'s
+category, not code.
+
+## The method, and what the evidence now says
+
+Three rows, three independent reviewer streams, fifteen rounds between them, and
+the same sentence in all three: **I fix the reported instance, not the
+category.** Each fix was correct about the case in front of it and blind to a
+sibling one step away — the command name, then a non-unique tuple, then the
+section shape, then *when* the shape is read.
+
+The reviewers also caught the same defect in my **tests**, four separate times:
+a fixture default that measured the state next door; a refusal that fired for an
+unrelated reason; an asserted fact the system re-derives elsewhere; and a legend
+table appended to the wrong section, leaving a whole shape untested. Twice I
+caught this myself by mutation. Twice I did not — and once I read a mutation
+returning "2 failures, as expected" without asking why it was not 3.
+
+What I would change: enumerate the state space **before** writing the fix, the
+way these reviewers do, and treat every green mutation as a finding rather than
+a formality.
+
+## The process lesson, logged three times
+
+A commit message's claims are checked against **the branch**. Evidence files
+written to the PMO tree and `## Intake` rows filed on `main` are not in the
+diff, and reviewers correctly reported them as missing twice. Baselines must
+name their runner: the two disagree on this repo.

+# Hand-off — the night of 2026-08-29 → 30
+
+> Written by the `work` lane as the night ran. Everything below is either
+> measured here or attributed to who measured it.
+
+## Read these three first
+
+**1. `bash tests/run` writes Perry state into the repository it runs in.**
+Four files — `.perry/events.jsonl`, `perry/BOARD.md`, `perry/intake.jsonl`,
+`perry/journal/<today>.md` — via an `intake-sweep` that discharges a real board
+row. Proved by controlled experiment: restore the four, run the suite, the same
+four move again. **The sweep is idempotent, which is why a second run looks
+clean** — the natural check, run twice and diff, reports nothing. Filed as
+**`TASK-249`** (P1). Two agents reached this from opposite ends within an hour,
+neither looking for it. It matters for every number taken tonight, because two of
+the suite's three standing failures are data-dependent on board state — so the
+suite perturbs the state its own results depend on.
+
+**2. `USER-909` is open and it is the one to read first.** `perry-decide`
+**reissues** a retired ADR id and `perry-task` does not. Delete `ADR-011`'s file
+and the next mint hands out `011` again — and before `TASK-235` it was
+*non-deterministic*, because an unrelated write re-rendered the index. An ADR id
+is an address: `ADR-007` is cited by name in `ADR-010`, in `DESIGN-013` and in
+three task rows. Recommendation is (b) then (a) — stop the deletion that creates
+the problem, then give `perry-decide` the event surface. But (b) changes what a
+decision record *is*, which is yours.
+
+**3. Every baseline in this project now needs a tree AND an hour.** Not a number.
+`TASK-233`'s round 1 measured "2 failures" and it reproduces as **3 at the same
+commit** — the commit did not change, the board did. Three of the suite's
+failures are data-dependent: two on `conformance.in_progress_with_no_live_run`,
+and one on whether a row's Next action **prose** contains an enum word.
+
+## Closed tonight — TEN rows, all at V4 with a fresh-context reviewer
+
+| row | what |
+|---|---|
+| `TASK-095` | the track register: one drift rule, owned by `perry-lint`. First PASS after **five** FAILs. |
+| `TASK-157` | a phase KR is declared once. Its restore point hid **eight silently deleted KR→OKR edges**. |
+| `TASK-203` | an ordinary write may never shrink a canonical store. **Phase 003 DoD Must-Have 2.** Five rounds. |
+| `TASK-214` | closed by `TASK-235`, and **larger than filed** — id reissue was non-deterministic. |
+| `TASK-226` | the phantom conformance row: **no defect**. The user ran the documented writer in their own shell. |
+| `TASK-230` | the suite is scheduled longest-first. Its restore point **silently dropped 14 tests**. |
+| `TASK-233` | the config readers ask the store. |
+| `TASK-235` | `DECISIONS.md` stops existing. |
+| `TASK-241` | a decorated row in `.perry/conformance.md` is not a declaration. |
+| `TASK-050` | **one `header_index()`** — the row that had failed seven rounds when the night began, and eleven when it closed. |
+
+**All six declared stores now exist** and `perry-lint` prints a drift verdict for
+each: tasks 243/0, risks 4/0, intake 37/0, asks 13/0, OKR 36/0, config 9/0.
+`P003-O1-KR1` moved 4→6 of 6 and `P003-O1-KR2` 2→6 of 6. **Recording those KRs is
+the `goals` lane's write, not mine** — see `handoff/2026-08-29-goals-lane-after-design-013.md`.
+
+## The pattern that paid, three times
+
+Three agents were killed mid-run and the PMO committed their uncommitted work as
+**restore points, saying explicitly that nothing in them was verified**. The next
+agent was told to treat each inherited RESULT as a **hypothesis** and audit it.
+All three were wrong in ways that would have shipped:
+
+- `TASK-157` — a guard tested on one of its two questions; deleting the untested
+  half left the whole suite's failure set **byte-identical**. And eight KR→OKR
+  edges replaced by prose from the wrong table, by a row whose entire purpose is
+  that a KR is declared once.
+- `TASK-230` — the `--ids` accounting silently dropped **14 tests**, by the
+  function whose whole job is to say which tests ran. 99.5% right.
+- `TASK-241`'s and `TASK-233`'s rounds each shipped a **completeness claim written
+  from intent rather than from a measurement**, and each was caught by a reviewer.
+
+The rule `TASK-233` derived from its own error now governs this project's reports:
+**a sentence of the form "these were the rest" is a measurement, needing a command
+whose output is the empty set, or it should be written as a count.**
+
+## `TASK-050` closed, and why it took eleven rounds to be closeable
+
+`USER-904` chose option C: stop building a better DETECTOR and make the defect
+structurally impossible. Ten rounds had tried to recognise the shape; each was
+defeated. What landed is `header_index()` as the only header fold, 59 converted
+sites, and a guard in three parts — a static net over the **symbol** with no
+allowlist of variable names anywhere, a runtime watch driving 24 readers **pinned
+by set equality** so it cannot fall behind a conversion, and a census of all 76
+sites.
+
+**The remainder is 8 and it is measured**, which is the whole difference from
+round 10 — that round was failed for asserting the uncovered set was empty when
+twelve was measurable. Its reviewer rebuilt the eight independently, and validated
+the static census by planting at **all 76 sites one at a time**: agreement 76 of
+76.
+
+The last pass is the one to read. The round's self-sweep was bounded at "whole
+`if` tests, not conjuncts", declared in writing — and the reviewer ran the sweep
+that bound excluded and found that dropping **one conjunct** makes the net report
+a legitimate value normalizer while the whole corpus stays silent. The author did
+not patch the line: it gave the structural reason the bound was wrong — *a
+criterion-4 failure is a test that fires too OFTEN, so only a strengthening
+mutation reaches one* — extended the sweep, and **found a second live instance**.
+Of the greens that remain it probed four and states the other 22 as **unprobed
+rather than harmless**.
+
+## Nothing was in flight WHEN THIS LINE WAS WRITTEN — see the last section, it is now false
+
+Every branch is merged and every worktree is clean. No agent is running.
+
+**`main`'s baseline is FOUR failures in three modules** on a clean `git archive`
+of HEAD at 09:42: 103 modules / 3098 tests / 4. Two agents measured the *same
+commit* an hour apart and got 4 and 3, and the cause is now **named and it is not
+the board**: `tests/run` offers **three numbers that all look like a failure
+count** — `^FAIL:` lines give 3, the per-module `FAILED (failures=N)` sum gives 4,
+and the summary line reads `N module(s) red`, also 3. **Only the sum is the
+answer.** One failure prints as a bare traceback with no `FAIL:` prefix while the
+other three carry it. Filed as **`TASK-251`**. Three of the four are data-dependent:
+two on `conformance.in_progress_with_no_live_run`, one on whether a row's `Next
+action` **prose** contains an enum word, and one on which evidence document the
+heading walk attributes to which row. A suite whose failure count moves with the
+project's own record cannot decide whether a branch regressed anything unless
+both sides are measured in the same minute. Three are the standing ones. The
+fourth appeared **when `TASK-050` closed**, and it is worth reading rather than
+fixing:
+
+`test_heading_title § test_none_of_them_contains_its_own_id` now flags
+`perry/evidence/2026-08/TASK-050-053-057-060-v4-review.md`, headed *"V4 review —
+TASK-050 / 053 / 057 / 060"*. The file is from **2026-08-18**; the test was green
+at `d527942^` and red after the close, because closing a row changed which
+evidence the walk attributes to it. So a twelve-day-old violation surfaced — and
+the violation is arguable: a document covering four rows **should** name them.
+The rule assumes one document per row. **Filed. The file must not be renamed to
+make the test pass** — rewriting a historical evidence document to satisfy a
+check is the failure this project guards against everywhere else.
+
+And `TASK-249` reproduced a fourth time, on `main`, by me: the four files moved
+again after that verification run. That is now four independent confirmations
+from four agents, none of whom were looking for it.
+
+## What I got wrong, and it is not a short list
+
+- **I truncated the event log.** Resolving a merge conflict I ran
+  `git show :2:… > .perry/events.jsonl` after the merge had already ABORTED —
+  I did not check its exit status, and `>` truncates before the command runs.
+  1,333 events and 187 journal lines to zero, then committed as a merge that had
+  not happened, on a commit with one parent. Restored from git and re-appended;
+  the false commit was reset. `9c771c9` carries the full account.
+- **"exits 0" was `head`'s exit code.** I filed an intake row against
+  `perry-config render` on a reading taken through a pipe. It exits **2**. The row
+  is dropped with the correction; a `TASK-233` agent caught it.
+- **A merge commit claimed two files existed** when `perry-lint` said otherwise in
+  the same breath. Amended.
+- **I put a stale figure into three review briefs** — "a live-board tree measures
+  5 failures" — after the number had moved. An agent hit it, correctly did not
+  chase it, and reported it.
+- **I attributed a proof to someone who never made it.** `TASK-241`'s spec said
+  the per-row round trip was one "which the reviewer showed is a complete detector
+  for this class". The reviewer showed that of a **whole-file** check. The false
+  attribution travelled through a spec, a RESULT and one of my commit messages
+  before a second reviewer caught it.
+- **I ran eight agents on a machine that supports about four**, and three evidence
+  runs were corrupted or abandoned for it.
+
+## Rows filed from the night's findings
+
+`TASK-239` the decide lane is now fully ungated under ADR-004 · `TASK-240` an ADR
+id can be reissued · `TASK-242` `linkage-kr-exists` proves *some* phase has edges
+· `TASK-243` a count-preserving substitution destroys records while drift goes
+DOWN · `TASK-244` the suite's floor is one module · `TASK-245` `tests/parallel`
+`main()` has never had coverage · `TASK-246` an unreadable row is deleted by the
+next declare · `TASK-247` three sites still ask "is there a config.md" ·
+`TASK-248` a row inside `<pre>` still declares · `TASK-249` the suite writes to
+its own repository.
+
+
+## What is startable now
+
+`TASK-050` closing unblocks **`TASK-232`** (rename `viewer/`, which is not dead
+code — it is the entire read side, and its name is why a reader asked whether it
+could be deleted) and **`TASK-234`** (`.perry/conformance.md` becomes a store,
+which dissolves `TASK-246` and `TASK-248` rather than fixing them).
+
+`DESIGN-013`'s chain is next: **`TASK-236`** (`OKR.md` drops its KR tables) is
+blocked on `TASK-181`/`TASK-182`, and that ordering is load-bearing — `TASK-182`
+is the completeness proof that `okr.jsonl` holds what the tables hold, and running
+it after the deletion would make it pass vacuously. **`TASK-237`** (`BOARD.md`
+stops existing, under `ADR-010`) waits on `TASK-236`'s written report on whether a
+CLI render is a good enough reading surface, and stops if that report is negative.
+
+Ten rows were filed from the night's own findings: `TASK-239` through `TASK-249`.
+
+---
+
+## After this hand-off was written — the 04:00–10:45 stretch
+
+The `Nothing is in flight` heading above was true when I wrote it and is not
+true now. This section is what happened after, and it supersedes that heading.
+
+### Closed — TASK-243, making it eleven
+
+`coding/task-243-substitution` is merged. The count-preserving substitution
+row, reviewed at `980c830`, PASS, with two corrections at `f2c4925` that left
+`bin/perry-task` **byte-identical to the reviewed tree** — the corrections
+were test-side only, and I verified that on the merged result, not just on
+the branch: `git diff 980c830 HEAD -- bin/perry-task` is empty.
+
+The correction that mattered: the `len(lost) > 5` branch was **unreachable
+from the whole existing module**, because every other board in it stages at
+most three losses. The new test stages a nine-row `WIDE_INTAKE` with seven,
+and runs the control first with
+`assertGreater(staged.n, SUBSTITUTION_RECORDS_SHOWN)` — so the fixture cannot
+quietly shrink back under the branch it exists to reach. 13 of 13 mutations
+die. Merge probe rc=0, zero conflicts; merge-tree suite 104 modules · 3124
+tests · the same four pre-existing failures.
+
+### TASK-251 now has its mechanism, and it is worse than a formatting quirk
+
+The TASK-249 agent found it **while retracting a number that this very trap
+had produced**. `tests/parallel:283`:
+
+```
+print("\n".join(r["err"].strip().splitlines()[-25:]))
+```
+
+A red module's stderr is truncated to its **last 25 lines, with nothing
+visibly elided**. `test_diagnose` fails twice; the second failure's `FAIL:`
+header survives that window and the first one's does not, so the first
+arrives as a bare traceback with no prefix. That is the entire trap:
+
+| what you run | what you get | right? |
+|---|---|---|
+| `grep -c '^FAIL:'` | 3 | no — undercounts by the truncated header |
+| the summary line `N module(s) red` | 3 | no — that is a count of MODULES |
+| sum of per-module `FAILED (failures=N)` | **4** | **yes** |
+
+It has caught three agents in twelve hours. One of them had documented the
+trap in its own result before walking into it. One of them used it to accuse
+a correct measurement of being wrong. Every review brief I send now carries
+the counting rule in its own section near the top.
+
+### In flight right now — two delta reviews
+
+| row | branch / tip | what is being attacked |
+|---|---|---|
+| TASK-249 | `coding/task-249-suite-writes` `8dfd25e` | the refuse-to-start guard on `PERRY_PROJECT`; four deleted `IGNORE_DIRS` names |
+| TASK-234 | `coding/task-234-conformance-store` `7d3f93f` | the claimed **equivalent mutant**; a helper hardened under 17 call sites |
+
+Both are delta reviews, not re-derivations. In each brief I named the one
+claim most likely to be how a real defect gets excused, and asked for that
+one to be broken rather than confirmed — the equivalent-mutant claim on 234,
+and the two deletions on 249.
+
+I held the dispatch cap at its default 2 rather than raising it for a third.
+The cap exists because eight agents on this machine cost three evidence runs
+in one evening; three concurrent full suites at 8 workers each is the same
+mistake in a smaller size.
+
+### Ready to merge, needs a review slot — TASK-239
+
+`coding/task-239-decide-gate`, tip `6a93d49`. Corrections in. Its argument is
+refounded on the strong form — **`decide` writes no state files, so ADR-004's
+sentence has nothing here to quantify over; no amendment is needed, only a
+record.** Open item 1 shrank accordingly, from *an ADR amending ADR-004's
+scope* to *the user confirms the reading*. That is the first decision waiting
+for you.
+
+It withdrew its own Finding 1 as phrased and kept the part that survives —
+**reading is not refusing**: a `files[]` entry adds no parse, it makes a
+gatekeeper out of a tolerant reader. It also found a **third** `gate(` call
+site the review had missed — `perry_md_store.py:1157`, alongside
+`perry-task:7194` and `perry-goals:3251` — and independently reproduced
+`perry-tasks render --write` rewriting `BOARD.md` rc=0 in the same minute
+`perry-task add` refuses on that file for want of a declaration. `--dry-run`
+writes too.
+
+### One row filed against the night's own work
+
+A signed-off test pins a line number by hand, and the corrections moved it
+**374 → 402 — the second move inside one row's lifetime**. The TASK-239 agent
+raised it against itself. A pin that must be re-pinned every time the section
+above it grows is pinning the layout, not the behaviour, and every re-pin is
+a chance to re-point it at the wrong line while the test stays green.
+
+### Still open, unchanged, and still yours
+
+- **USER-909** — `perry-decide` reissues a retired ADR id while `perry-task`
+  never does. An ADR id is an address: `ADR-007` is cited by name in
+  `ADR-010`, `DESIGN-013` and three rows. Recommendation on the row: (b)
+  then (a).
+- **USER-908 part (b)** — the unpushed-history rewrite, authorised, deferred
+  until the in-flight branches land. **The window closes on push.** I have
+  not pushed `main` and will not before you rule.

Row is 3 registers, not 2 (asks stays out of scope but the RESULT now owes the follow-up row).

+- [USER-904] — → pending · TASK-050 has now failed SEVEN V4 rounds and needs a decision, not a round 8. Each round's fix moved the same defect rather than closing it: round 5's reviewer defeated a regex, round 6 replaced it with an AST walk, and round 7 showed the walk's gate is still an allowlist of variable names (ROW_NAMES, 11 entries). Measured: of 829 mapping constructs in the 18 readers, 59 are classified as row-cell sources and 35 of those are the bare name 'header'; FOUR LIVE header resolutions (viewer/parsers.py:1827, bin/perry-task:6029 and :6200, bin/perry-tasks:925) can be reverted to the exact historical defect with the whole 2793-test suite green, and parsers.py:1827 silently drops a KR when reverted. In the other direction the check now reports CORRECT code — 6 of 8 legitimate shapes flagged, including the exact latent risk round 5 recorded. Blind to four of the tree's own header resolutions AND loud about a keyword tokenizer: both failure modes the spec names, in one artefact. THE CHOICE. (A) Round 8, same shape — widen the source-expression recognition. The record says this is the fourth time that has moved the defect. (B) Invert the burden: flag EVERY case-folding map in a reader, and require the ~30 legitimate value normalizers to carry a one-line opt-out marker. Correct code declares itself once; anything new is caught by default. Cost: touching 30 live sites and a new convention. (C) RECOMMENDED — make it structurally impossible: one header_index() function becomes the only thing allowed to fold a header, and the guard becomes 'nothing outside it calls squash on a row', which is a one-symbol surface instead of a shape. This is the move ADR-007 already made for stores. (D) Accept the guard as advisory rather than a gate, close the row at a lower rung, and document the limitation. My recommendation is C, with B as the fallback. All four are design decisions with blast radius beyond this row, which is why this is an ask and not a dispatch.

+- [USER-905] — → pending · TASK-095 has now failed FIVE V4 rounds and needs a decision, not a round 6. I caused three of the five, and every one is the same shape: two situations answered as one, one step to the left of the last. Round 1 collapsed four None-returns. Round 2 collapsed 'no-track-record' into unusable and hard-blocked three of this repo's own fixtures. Round 3 collapsed the two default cases. Round 4 filtered on the NAME 'main' instead of on whether the table DECLARED it. Round 5 compares on names over records, so a record that CONTRADICTS a declared row counts as carrying it. THE DECISION, and the reviewer states it cleanly: two principles are each defensible applied once, and round 5 applies one to the synthesised main and the other to the recorded main. (A) 'A declared row the register contradicts is drift' — then a table declaring queue/4/3d beside a store recording project must WARN, and perry-lint already computes exactly that. (B) 'The store is truth and the table is a stale projection' — then the trackless case must be SILENT too, because the register answered there as well. Pick one and it applies everywhere; the current code cannot be right because it holds both. SECOND, SEPARATE DECISION — the refusal WIDTH, and it is urgent because I made it worse: I widened the write refusal from source=store-default to source=store, and the reviewer measured three ordinary hand-edit workflows now hard-blocked that wrote at 45a355d AND at round 4. On the third — derive the store from a two-track table, then hand-swap one row — 'perry-config write --from-file', the ONLY command both refusal messages name, exits 1. The block cannot be cleared by the documented remedy. Options: revert to round 4's narrower width; make it a warning rather than a refusal; or fix perry-config so the remedy works. THIRD: the perry-goals half of the guard is a tautology — deleting it leaves the full 2875-test suite at exactly the baseline, which is the same defect TestTheGoalsLaneRefusesToo's own docstring records against round 2. My recommendation: (A) for the principle, because perry-lint already owns that rule and the root cause across three rounds has been re-deriving it differently; plus revert the refusal width to round 4's until perry-config's remedy is fixed. All of this is on an UNMERGED branch, so nothing is harmed in production. Evidence: evidence/2026-08/TASK-095-round5-v4-review.md. · blocks: TASK-095

+- [USER-906] — → pending · TASK-203 has now failed THREE V4 rounds, all three mine, and every one has ended with the same defect: an ordinary command silently truncates a canonical register store. I said I would escalate rather than attempt a fourth, so here it is. ROUND 3's FAIL: the gate is read at a moment the command controls. cmd_add's queue-mode branch calls ensure_section('Intake') BEFORE commit() asks the gate, so the gate sees a freshly created, readable, EMPTY table, answers yes, derives [] and writes zero bytes. Measured: a 291-byte 3-record intake.jsonl goes to 0 on 'perry-task add --track ops' with rc 0, byte-identical on 45a355d, and perry-lint reports '0 row(s) drifted'. It is round 1's blocking finding word for word — round 2 closed it for the project-mode track and never asked the queue-mode track, which is the mode ## Intake exists for. Three more doors of the same shape: intake 3->1, ask 3->1, risk-add 3->1, all rc 0, all preserved on base. THE DECISION. (A) Evaluate the gate against the board AS IT WAS AT COMMAND ENTRY, not after the command mutated it — snapshot the shape before any board write. Principled and small, but it is the fourth 'move the question' fix on this row and the first three all looked principled too. (B) RECOMMENDED — make it structurally impossible: an ordinary write may never SHRINK a canonical store. Only an explicit removal command (purge, resolve-intake, intake-sweep) may reduce the record count, and any derivation that would produce fewer records than the store holds is a refusal, not a write. That is one invariant covering every door found in three rounds — the command name, the non-unique tuple, the four section shapes, and the ensure_section ordering — instead of a fourth predicate. (C) Revert TASK-203 entirely and reconsider the row. It has introduced a store-truncation regression in all three rounds; before it, intake.jsonl did not exist and could not be wrong. That is a real 'should we do this at all' question and it deserves an answer, not an assumption. (D) Narrow the scope to the risks register only, which is the one that already existed, and defer intake/asks. NOTE THIS AFFECTS THE PHASE: TASK-203 is the ONLY row under P003-O1-KR1, and DoD Must-Have 2 names intake.jsonl and asks.jsonl explicitly, so (C) or (D) means the phase misses that Must-Have deliberately rather than by accident. Also filed from this round: my third shape test is VACUOUS (the legend table lands under ## Top risks because ensure_section anchors ## Intake before ## P0, so the foreign shape has no test on any register); the uniqueness test cannot distinguish uniqueness from adjacency; load_register_records lets a JSONDecodeError escape as an uncaught traceback where every other failure in that file is a Refused.

This is my recommendation: the KR was never really about the file, it was about a reader being able to tell truth from projection, and that need survives. (b) DROP the KR and TASK-199, recording that phase 003 closes with one KR withdrawn by a decision made DURING the phase. Honest, and it makes the phase score mean what it says. (c) Keep both and mark the boundary on a file scheduled for deletion — cheapest to do, hardest to defend. NOTE ON PROCESS: TASK-199 has been left not_started and untouched on purpose. Dropping the row is the visible half of dropping the KR, and doing the visible half first would make the record say the KR FAILED rather than that it was WITHDRAWN.

+- [USER-908] — → pending · May Perry rewrite unpushed local history to repair commit 0d68034? MEASURED 2026-08-29: at that commit, every perry-task write on a project carrying .perry/config.jsonl dies with AttributeError: module 'perry_state' has no attribute 'defaulted_over_a_declaring_table' — bin/perry-task at :6773 calls a function that arrives one commit later. The TASK-213 commit also carries the bin/perry-task half of TASK-095 round 4. Its own message's suite claim is FALSE at that commit. The branch tip was whole and main is whole; only this one commit does not build. It is now in main's history via the 777d021 merge, so a git bisect across the 20 commits after it gets a false 'broken' verdict there. WHY THIS IS AN ASK: .perry/hook.md lists git history rewrites — push --force, --force-with-lease, rebase onto main, tag deletion — as high-stakes operations requiring your explicit authorization. I filed it rather than doing it, and a V4 reviewer endorsed that: 'That reasoning is correct and I endorse it — do not rewrite.' WHAT CHANGED SINCE: origin/main is at 45a355d and local main is at 91e5351, so all 27 commits including this one are UNPUSHED. Nobody has seen this history. That materially lowers the risk the hook rule is written for — the rule protects shared history, and this is not shared yet. OPTIONS. (a) LEAVE IT, and document the bad commit so a future bisect knows to skip it. Zero risk, permanent small cost, and the record keeps an honest scar. (b) REWRITE the unpushed history to move the perry-task hunk into the commit that owns it, then verify every commit in the range builds. My recommendation IF you want a clean history, because unpushed is the only moment this is cheap — after a push it becomes a shared-history rewrite and the answer should be (a) forever. (c) Leave the history and add a test that every commit on main builds standalone, so this class is caught at the next merge rather than by a person. Slower, and it does not fix this commit. My recommendation is (b) THEN (c) — repair it while it is still free, and add the guard so the next one is caught by a machine. But this is your call and I will not touch history without it.

Option C as decided in USER-904: viewer/tables.py header_index(cells, alias=None) claimed the only header fold in the repo, HeaderIndex a list[str] subclass so 67 converted sites across 10 files keep zip/.index/in/== unchanged. All six named escaping sites converted. Nine md5-verified mutations, each reddening a named test; parsers.py:1828 reddens three including a BEHAVIOURAL one — on main that revert loses a KR with 2882 tests green. Guard is a symbol net with no allowlist under any spelling, plus a runtime net, plus a static walk that DROPPED ROW_NAMES rather than extending it. bash tests/run: 99 modules / 2893 tests / the same 3 pre-existing failures. Planting: 30 of 30 caught (round 7 was 4 of 25), now with two runs behind it. TWO SELF-REPORTED SHORTFALLS the review must weigh rather than wave through: (1) 1 of 8 legitimate shapes STILL falsely flagged where the amendment requires zero — declared, not hidden, argued indistinguishable because the two cases differ only in the receiver's name; the reviewer is asked whether that argument is true or stops one step early the way rounds 5/6/7 each did, and separately whether one false positive defeats option C's thesis. (2) 68e63cf RETRACTS a baseline claim: no unittest discover count was ever measured this round, and the runners-disagree-by-3 figure is carried from the brief rather than measured. The reviewer is told to check whether that retraction is complete, and that my own brief carried the same unmeasured claim.
+- [TASK-203] next action · ROUND 4 IN PROGRESS, resumed 2026-08-29 — NOT ready for review. Branch coding/task-203-round4, three commits on 6c0d041, tip 6d45388, committed code clean. The agent was killed mid-mutation-run under load average 34 (seven concurrent dispatches, mine); bin/perry-task was left DIRTY with the mutation 'if True: return' applied at :2212, which disables the whole invariant, and no RESULT file was written. Resumed with instructions to restore the mutation with an md5 check first. WHAT THE ROUND CLAIMS SO FAR: the invariant is bin/perry-task refuse_to_shrink, ONE function, two call sites — commit() for tasks.jsonl and register_change() for the three registers — asking nothing about the command, the identity or the board, which is why option A was not needed. Step 1 (762bee1) is DELIBERATELY RED and reproduces the merge-hold defect: 24 failures / 7 errors including 4 records to 0 at rc 0. Step 2 (b09776d) turns the same module green at 37. On a probe with this repository's queue-track shape: 3 records in, ## Intake deleted by hand, add --track ops now rc=1, md5 unchanged, and perry-lint says '1 error(s) · 3 record(s), 3 row(s) drifted' where it used to say '0 error(s) · 0 record(s), 0 drifted'. Suite 99 modules / 2919 tests / the same 3 pre-existing failures. TWO GAPS THE AGENT FLAGGED ITSELF and was told to keep as first-class findings: removing the tasks.jsonl call site reddens NOTHING, so the guard there survives its own deletion — the exact defect TASK-095 was failed for; and resolve-intake does not reduce any count despite being one of the three names USER-906 put in the invariant.

The reviewer attacked the load-bearing claim first and ruled the M11 equivalence argument CORRECT by reading the control flow: both production callers derive tracks/source from the same declared_tracks_detail call and stored_tracks reaches TRACKS_STORE_DEFAULT on exactly one return, so after the gate 'have' provably equals the round 4 literal — and that is what USER-905 Decision 2 ASKED for, because it sits on the REFUSAL, not the drift rule. The drift rule is now perry_md_store.plan, the same call perry-lint makes. The other three greens are genuine equivalents; M22, the one that was a crash path, is now 1 ERROR. Verified with the reviewer's OWN fixtures, not the author's helpers: two stores one verdict (opposite responses at base, all five tools agreeing at head); parse_tracks( 2 lines at head vs 3 at base; W1/W2/W3 exit=1 to exit=0 with W3's remedy still failing on both trees; the remedy pin proved REAL by simulating the fix and watching exactly that test go red; M5 kills the tautology; state 7 contradicted=['intake','main'] with MODE-02; the zh path identical at every state; all 27 anchors matching, 17 mutations re-run with every count and RED name matching. The reviewer also ran the runner the author declined to: unittest discover 2882/6 vs 2902/6, identical sets. The stderr drift warning was ruled IN SCOPE and correct, measured — three clean workflows byte-identical, no exit code going 0 to 1. ONE NON-BLOCKING FINDING, sent back: bin/perry-state:1022's startswith('track/') filter survives its own deletion with 56 tests green, and without it perry-task says 'the track register disagrees' about a hand-edited SETTING cell. Shipped code is correct; it needs one named test on the message. Merge after that lands.
+- [USER-909] — → pending · perry-decide REISSUES a retired ADR id, and perry-task does not — two tools, one contract, opposite answers. Measured by the TASK-235 agent 2026-08-29: delete ADR-011's file and the next mint hands out 011 again. perry-task purge retires an id through the append-only event log so it is never reissued; perry-decide writes NO events at all, so it has nothing to retire an id with. Worse, before TASK-235 the behaviour was NON-DETERMINISTIC: on main an unrelated write re-rendered the index and the next mint reissued anyway. THE STAKE: an ADR id is an address. ADR-007 is cited by name in ADR-010, in DESIGN-013, in three task rows and in this project's own commit messages. If 011 can name two different decisions, every one of those citations becomes ambiguous the moment an ADR is deleted and a new one minted. This did not matter while nobody deleted ADRs; TASK-235 is the row that made deletion ordinary. THE OPTIONS. (a) RECOMMENDED — perry-decide writes events like every other writer, and an id is retired the way perry-task retires one. This is the answer that makes the two tools agree rather than documenting why they differ, and DESIGN-004's whole posture is that every write goes through a tool and leaves a trace. Cost: perry-decide gains an event surface it does not have today. (b) Refuse the delete instead: an ADR file may not be removed, only superseded — which is arguably what a decision record SHOULD mean, since ADR-005 and ADR-007 are cited as history and history is not deleted. Cheaper, and it may be more correct in principle. (c) Accept reissue, and document that an ADR id is a slot rather than an address. Honest but it silently breaks every existing citation. (d) Leave it declared as it is now — the TASK-235 agent pinned the disagreement with a named test rather than resolving it silently, so nothing is hidden and the row can close. My recommendation is (b) THEN (a): stop the deletion that creates the problem, then give perry-decide the event surface so the two tools stop disagreeing on principle rather than by accident. But (b) changes what a decision record IS, which is yours and not mine.

+
+That is the **third** instance in two days of the limiter's bookkeeping

+claiming to be in flight against a limiter that says nothing is running, and
+that check is cheap: both numbers are already on the standup payload.
+
+Neither row was closed on the commit message's word. Both were re-measured from

+finish is not evidence.
+

+  scratch copy per the spec's `Executor: manual`. **`P003-O1-KR3` is at target,
+  6 of 6** — and unlike `P002-O1-KR3`, which scored 0.33 for saying "reported"
+  without saying by what, all six numbers are removals that actually happened.
+
+**`TASK-095` → `review`, not `done`.** `P003-O2-KR1` measures **0**:
+`declared_tracks()` is the one reader and `grep -nE 'parse_tracks\('` over `bin/`
+returns the definition and a single guarded fallback. But the rung is **V4**, and
+the session that verified it is the session that dispatched it. It cannot close
+itself. A fresh reviewer against written criteria is owed.
+
+**`TASK-203` pre-flight, and the finding nobody ordered.** Its spec asks for the
+risks half to be re-measured before any fix, with permission to narrow the row
+if it does not reproduce. It reproduces, and the row widens instead:
+`risks.jsonl` is byte-identical after both `risk-add` and `risk-clear`;
+`intake.jsonl` and `asks.jsonl` stay absent after an ordinary write; only
+`tasks.jsonl` actually writes its store.
+
+All five commands printed `→ store + journal + BOARD.md + event`. **`→ store` is
+template text.** In three registers of four it is false at the moment it is
+printed — and `bin/perry-task`'s own header promises that a failed store write is
+*"reported, not raised."* It is neither. `risks.jsonl` has been a snapshot
+wearing a store's name since the day it was imported, and `perry-lint` calls it
+clean because the board it is compared against is rendered from the same path
+the store was minted from.
+
+Filed to `## Intake` rather than fixed here: the unconditional success line, and
+the tasks store being the only one of six whose census line does not name it.
+
+**Handed to `goals` (this lane does not write `phase/`)**: `P003-O1-KR2` and
+`P003-O1-KR3` both have evidence and both sit at target with `current` still

+### TASK-232 — viewer/ is named for a web console deleted under TASK-178, and a reader just called it dead code
+
+- **Owner**: Coding Agent
+- **Priority**: P2
+- **Track / mode**: main / project
+- **Deliverable**: viewer/parsers.py and viewer/tables.py live under a directory named for what they do (recommended parse/); every import, every sys.path.insert and every live contract that names the old path is updated; and the historical record is NOT rewritten. Measured 2026-08-29 at e1cd17c: 60 code files under bin/, tests/ and viewer/ mention the name, 35 of them via sys.path.insert and 43 via a bare 'import parsers'/'import tables'; 9 live docs and contracts name the path, including schema/state-schema.json, schema/README.md, bin/README.md, reference/i18n.md, reference/adoption.md, reference/config.md and work/reference/dispatch.md. A further 169 files under perry/evidence, perry/journal, perry/design, perry/decisions, perry/handoff and perry/weekly also carry the name and MUST be left alone — they are the record of what happened, and rewriting them would make the record disagree with itself.
+- **Verification**: bash tests/run is at the baseline of the commit the work forks from, named by runner and tree, with no test edited except for the path it imports. grep -rn 'viewer' over bin/ tests/ viewer/ schema/ reference/ work/ templates/ and .perry/ returns zero hits outside the historical record. git log --follow resolves both moved files, so blame survives. And a mutation: revert one sys.path.insert to the old path and show a named test goes red rather than silently importing a stale copy.
+- **Dependencies**: TASK-050
+- **Out of scope**: Any behaviour change. This row moves files and updates the names that point at them; if a reader looks wrong on the way past, file it, do not fix it here.

+### TASK-233 — .perry/config.md is load-bearing because six settings and the conformance gate still read it, not because the store lacks them
+
+- **Owner**: Coding Agent
+- **Priority**: P1
+- **Track / mode**: main / project
+- **Deliverable**: Three things, and the file survives all three. (1) parse_config and perry-conform read .perry/config.jsonl when it exists, with the markdown as the fallback for a project that has no store — the arrangement ## Tracks already has, so an absent markdown stops meaning 'never configured'. (2) perry-config render rebuilds .perry/config.md from the store ALONE, with no target file present, and returns a non-zero exit when it cannot. (3) The 27 lines of prose have a declared home that a render does not destroy — either moved to reference/config.md, which already exists and is where this class of explanation lives, or preserved by a stated contract the renderer honours. When all three hold, .perry/config.md is a projection in the same sense BOARD.md is, and whether it should exist at all becomes a question worth asking; it is NOT a question worth asking before then, because today the answer is forced by the readers rather than chosen.
+- **Verification**: Delete .perry/config.md on a project whose store is populated: every setting still resolves, perry-conform still reports the declared gate rather than the default, and perry-config render --write rebuilds the file. Byte-compare the rebuilt file against the original, prose included, or state exactly which lines are not recoverable and where they went. Mutation: revert the store read in parse_config to the regex and show a NAMED test goes red — the previous conversion of ## Tracks shipped a guard on the perry-goals side that could be deleted with the whole suite unchanged, so a guard that does not fail when removed does not count here. Baselines name both the runner and the tree.
+- **Dependencies**: TASK-095
+- **Out of scope**: Deleting .perry/config.md. That is the question this row makes askable, not the question it answers — and USER-903 already decided on 2026-08-28 that the file becomes a rendered projection, which is a different decision from removing it. Also out: the ## Tracks reader, which TASK-095 owns.

+### TASK-234 — .perry/conformance.md is a pure ledger with a hand-rolled table parser, and its phantom row has nowhere to record provenance
+
+- **Owner**: Coding Agent
+- **Priority**: P1
+- **Track / mode**: main / project
+- **Deliverable**: .perry/conformance.jsonl is the record, one JSON object per declaration, and .perry/conformance.md is GONE rather than rendered — perry-conform status is already the human surface and a ledger nobody reads for pleasure does not need a second face. Each record carries provenance the four-column table has no room for: which writer produced it, the event id, and the timestamp. read_conformance and the perry-conform writer are converted; nothing else needs to change, because nothing else touches the file. Withdrawing a declaration stays a hand deletion of one line, which a jsonl serves better than a table.
+- **Verification**: perry-conform status reports the same 24 declarations before and after, by path and shape version. The enforce gate still refuses an undeclared file and still names the same two roads. Mutation: revert read_conformance to the markdown reader and show a NAMED test goes red. The bolded-header case and the regex-group row case both get a test that would have caught the two historical defects, and each is shown red against the old parser. A file with an unreadable record still reports it as unreadable rather than as absent or as declared — that distinction is in the current ConformanceRecord and must survive. Baselines name both the runner and the tree.
+- **Dependencies**: TASK-050
+- **Out of scope**: Investigating TASK-226 itself. This row gives that investigation a place to look — a jsonl line can carry the writer and the event id, which the table cannot — but it does not explain the row that appeared on 2026-08-28. Also out: adding a rendered markdown projection. If one turns out to be wanted, that is a separate decision and it should be argued, not assumed.

+### TASK-235 — DECISIONS.md stops existing; perry-decide list is the surface
+
+- **Owner**: Coding Agent
+- **Priority**: P1
+- **Track / mode**: main / project
+- **Deliverable**: perry/DECISIONS.md is deleted, bin/perry-decide no longer writes it, and perry-decide list is the documented surface. Every reference to the file in SKILL.md, decide/SKILL.md, schema/ and reference/ is updated to name the command instead. schema/state-schema.json's claim for it is removed, and .perry/conformance.md's declaration row for it goes with it.
+- **Verification**: perry-decide list prints every ADR the deleted file listed, with the same status counts (10 active / 10 total at ADR-010). grep -rn 'DECISIONS.md' over bin/, tests/, schema/, reference/ and every SKILL.md returns zero live references — matches under perry/evidence, perry/journal, perry/design and perry/decisions are the historical record and stay. perry-lint is at 0 errors and does not report a missing claimed file. Mutation: restore the writer and show a NAMED test goes red. Baselines name both the runner and the tree.
+- **Dependencies**: —
+- **Out of scope**: Adding any replacement index file. DESIGN-013 section 4.1 records that the markdown link surface into decisions/ADR-*.md is GIVEN UP by this decision — a web reader lands in the directory listing. The draft recommended keeping a rendered view and that recommendation was declined. Do not re-add an index to make the loss go away; if it turns out to matter, that is a finding to report, not a thing to quietly fix.

+### TASK-236 — OKR.md drops its KR tables; perry-goals renders them — and reports whether a CLI render is a good enough read surface
+
+- **Owner**: Coding Agent
+- **Priority**: P1
+- **Track / mode**: main / project
+- **Deliverable**: perry/OKR.md keeps its prose sections and carries no KR tables. perry-goals gains a read-only render that prints them from okr.jsonl. The OKR table reader in viewer/parsers.py goes. AND, as a first-class deliverable rather than a note: a written report in the RESULT on whether the CLI render is a good enough reading surface — what it does better than the table, what it does worse, and what a human loses by having to run a command. That report is TASK-237's gate.
+- **Verification**: perry-goals prints all 34 KRs and both version records, and the numbers match okr.jsonl exactly. OKR.md's remaining prose is byte-identical to what it was, section for section — nothing was rewritten while the tables were removed. grep for the OKR table reader returns zero live call sites. Mutation: restore one table read and show a NAMED test goes red. perry-lint reports OKR store 36 records with a drift verdict that still means something after the table is gone, or the census line is changed to say what it now checks. Baselines name both the runner and the tree.
+- **Dependencies**: TASK-235
+- **Out of scope**: BOARD.md and DECISIONS.md — separate rows, TASK-237 and TASK-235. Also out: changing any KR's content. This row moves where the numbers live; it does not touch what they say.

+
+### TASK-237 — BOARD.md stops existing; the board is what a command prints
+
+- **Owner**: Coding Agent
+- **Priority**: P1
+- **Track / mode**: main / project
+- **Deliverable**: perry/BOARD.md is deleted. A command renders the board from tasks.jsonl and risks.jsonl, and it is good enough that a human running it sees what opening the file showed them — including a 2,825-byte Next action. The board table reader goes. Drift detection for the board, its render --write recovery and its half of the two-rename canonical pair go with it. The entrance ritual is rewritten in SKILL.md, work/SKILL.md, goals/SKILL.md and decide/SKILL.md, all four of which today open by reading the board — that rewrite is INSIDE this row, not a follow-up.
+- **Verification**: The render shows every row the file showed, by id, with every cell, and a 2,825-byte cell is readable in it. A session started from a clean context reaches the same understanding of the work from the render as from the file — run it, do not assert it. perry-lint is at 0 errors with no claimed-file-missing report. Mutation: restore the board reader and show a NAMED test goes red. The two real projects, gimegime-pmo and PolyForge, are checked against ADR-004's migrate-once posture — this must not become a second migration for a project that already ran one. Baselines name both the runner and the tree.
+- **Dependencies**: TASK-235, TASK-236
+- **Out of scope**: Moving the 2,825-byte Next action prose out of tasks.jsonl. DESIGN-013 section 5.1 names that as a KNOWN violation of its own rule — a store holding unschema'd prose — and section 8 asks whether it deserves its own design. It gets worse in relative terms after this row, because the store becomes the only home. Report it; do not fix it here.

+
+### TASK-238 — no commit on main may fail to build standalone, and nothing checks it
+
+- **Owner**: Coding Agent
+- **Priority**: P2
+- **Track / mode**: main / project
+- **Deliverable**: A check that every commit on main builds and imports standalone, run where a broken one is still cheap to fix — at merge, not by a person reading a commit message weeks later. It must catch the exact 0d68034 case: a caller landing one commit before the function it calls. Scope is the check, not the repair — repairing 0d68034 itself is USER-908 part (b), separate and sequenced after the current branches land.
+- **Verification**: Run it over the range 45a355d..main as it stands today and show it names 0d68034, by sha, with the AttributeError. Run it over a range with no such commit and show it is silent. Mutation: remove the check and show a NAMED test goes red. State its cost in wall-clock over 27 commits — if it is too slow to run at every merge it will be turned off, and a check nobody runs is worse than none because it reads as coverage. Baselines name both the runner and the tree.
+- **Dependencies**: —
+- **Out of scope**: Repairing 0d68034. That is USER-908 part (b), authorised and deliberately sequenced AFTER coding/task-050-header-index, coding/task-095-round6, coding/task-203-round4 and coding/task-157-kr-declared-once land — rewriting it changes every SHA after it, including those four branches' merge bases. Also out: enforcing this on every branch. The claim is about main.

+## Status changes
+
+- [intake] arrived 2026-08-30 · test_contract_key_parity's two witness tests are DATA-DEPENDENT on the live board — they fail whenever conformance.in_progress_with_no_live_run is non-empty, which is true of any repository with a row left in_progress and no dispatch marker for 4h; measured 2026-08-30 identical on 7f934d5 and on the pre-merge 9b53315, so a baseline of '3 failures' is only true of a board with no stalled rows. Third instance of this class after test_diagnose's queue-reconcile and the scratchpad-baseline race, and the first where the failing check is CORRECT — it is reporting a true fact about the board
+- [TASK-239] — → not_started · the decide lane is fully ungated under ADR-004 after TASK-235, and the comment that records it says the opposite · owner: Coding Agent · priority: P1
+- [TASK-050] review → in_progress · V4 round 8 FAIL; round 9 dispatched — the fix is a deletion, not a ninth widening
+- [TASK-203] review → in_progress · V4 round 4 FAIL — the fifth door is the exemption itself; round 5 dispatched
+- [TASK-050] next action · V4 ROUND 8: FAIL 2026-08-30, evidence/2026-08/TASK-050-round8-v4-review.md. Round 9 dispatched — and it is NOT a ninth widening: two of the three fixes are DELETIONS. WHAT THE REVIEWER VERIFIED RATHER THAN ACCEPTED, and none of it is to be touched: nine mutations reproduce with md5 restores; M9's split verdict exact; the ihdr drift case round 7 measured as escaping is now caught WITH NO ALLOWLIST ENTRY; parsers.py:1833 reverted loses the KR and reddens three named tests; the docstring-grep test genuinely gone; alias-after-fold exact (the property needed is alias∘squash = alias and it holds); no site found where the list subclass changes behaviour; criterion 5 driven end-to-end through four CLIs on a 64-cell half-bolded fixture, byte-identical. header_index() is right. THE THREE FAILURES. (1) THE CORPUS WAS PRUNED: '30 of 30' is measured on a corpus described as a superset of round 7's and is neither — round 7 Finding 2 names 'a scalar header-row test' and 'P23-P25, round 4's _is_python hole', neither is in it, and the labels P23-P25 were RE-USED for three different shapes so the omission is invisible in the numbering. Re-derived and planted with a control: all five variants escape BOTH nets, control caught. Honest fraction 30 of at least 33. The scalar class is structural — neither net inspects anything but a mapping construct, so read_conformance's historically damaging shape is outside both BY CONSTRUCTION, with a live instance at viewer/parsers.py:2582. (2) THE DEFEATED SHAPE NET WAS KEPT AND STILL GATES THE SUITE: appending an ordinary multi-value-cell normalizer to a real reader turns tests/run RED, and one failing test is named test_value_normalizers_are_not_flagged. NET 1 ALONE IS CLEAN ON ALL EIGHT SHAPES — a defence the author never makes. Round 9 deletes net 2. Also: ROW_NAMES survives and IS load-bearing (emptied, the harness drops to 22 of 30), plus a second name allowlist at header_rule.py:357-360, so round 8's 'dropped ROW_NAMES rather than extending it' is false; and perry-diagnose.md_table is watched by the closing test while contributing ZERO folds because it pre-strips decoration itself. (3) THE RETRACTION IS INCOMPLETE: 68e63cf added 6.9 but left 5's 'the runners disagree by 3' standing, and 6.9's own closing line is untrue of it; 2 says 67 call sites where its table says 58.
+- [TASK-203] next action · V4 ROUND 4: FAIL 2026-08-30, evidence/2026-08/TASK-203-round4-v4-review.md. Round 5 dispatched with a fix that stays INSIDE option B. THE INVARIANT ITSELF IS SOUND — the reviewer states refuse_to_shrink closes all four known doors and could not be broken from inside. THE FIFTH DOOR IS THE EXEMPTION: SHRINK_ALLOWED grants its licence BY COMMAND NAME AND WITHOUT A BOUND, so a listed command may shrink a store by any amount including a shrink it did not perform — and resolve-intake, which round 4's own finding established removes NO record at all, therefore holds an unbounded licence to destroy the whole store. Reproduced on this repository's own intake data: 11781 bytes / 28 records, 24 rows tidied off the board by hand (the /pmo triage state), then 'resolve-intake 1 --outcome dropped' returns rc 0 and leaves 1420 bytes / 4 records, with perry-lint reporting '0 error(s) · intake store: 4 record(s), 0 row(s) drifted'. Same signature as the merge-hold reproduction. intake-sweep has the same hole: reported sweeping 1 row, took a store 4 to 1. WHY THE ROUND'S OWN TEST COULD NOT CATCH IT: mutation MR (drop only resolve-intake from the allowlist) reddens two tests, BOTH assertions about the constant, because test_resolve_intake_is_not_blocked_and_does_not_in_fact_shrink runs on a CLEAN BOARD where no shrink is possible. The test offered as the record that the allowance is unused is the one test that cannot tell. THE FIX, no new predicate: an allowed command may shrink by exactly the count it declares removing — resolve-intake 0, intake-sweep the rows swept, purge 1. THE OTHER TWO GAPS ARE RULED AND CLOSED: keep the tasks.jsonl call site's two lines (the site is reached end-to-end, 14 test_purge red; only the refusal branch needs the monkeypatch and the docstring says so); and refusal frequency on real boards was MEASURED and does not block.
+- [TASK-240] — → not_started · an ADR id can be reissued, because perry-decide writes no events and has nothing to retire one with · owner: Coding Agent · priority: P1
+- [intake] arrived 2026-08-30 · measuring one tree's tool with another tree's PERRY_HOME silently loads the wrong schema and produces a confident wrong answer — the TASK-235 agent's first check APPEARED to refute its reviewer this way (main's perry-decide + the branch's PERRY_HOME found no files[id=decisions] and returned 'absent'), and every cross-tree measurement this project makes has the same trap; recorded in that row's RESULT section 7 B
+- [TASK-235] next action · V4 PASS 2026-08-30 with the required correction applied at 5de1ed5; evidence/2026-08/TASK-235-v4-review.md. Merging once the suite on the merge probe reports. THE CORRECTION: perry-decide's justification for dropping the ADR-004 gate closed with 'only the index write was ever gated', which is false — on a real main snapshot at ee0b36a with enforce and nothing declared, perry-decide new returns rc=1, refuses, and writes NO ADR body, while the branch returns rc=0 and writes ADR-001. The gate ran before the command and refused it entire. The clause now says so and tells the follow-up row to size itself as RESTORING a gate rather than closing a gap that was mostly open. Scope held: two files, and bin/perry-decide's diff is 2 comment lines out and 13 in with ZERO non-comment lines changed. WORTH KEEPING FROM THIS ROUND: the agent's first check appeared to REFUTE the reviewer, and that check was the broken one — it ran main's perry-decide with the BRANCH's PERRY_HOME, so it loaded the branch schema, found no files[id=decisions] and returned 'absent'. Recorded in the RESULT section 7 B as a silent way to measure the wrong thing, and filed separately. The declared gap is closed twice over: the reviewer's 458.4s / 2892 / 3 on a quiet machine, and the agent's own tests/parallel -j 4 on the same tree independently agreeing at 98 modules / 2892 tests / 613.6s / the same 3. The gap paragraph was KEPT rather than deleted — a gap declared and then closed is a different record from one that was never there.
+- [intake] arrived 2026-08-30 · test_board_render's test_every_rendered_field_moves_when_the_store_moves does assertNotIn(value, whole_row) on a row that contains a 2000-character Next action, so it goes red the moment any row's PROSE happens to contain an enum value — 'dropped ROW_NAMES' in a review summary was enough; 12+ live rows carry done/blocked/review/dropped/in_progress in their Next action today. This is ADR-007 rule 2 violated by a test: a field with an unbounded value space is prose and no regex asks it a question. The fix is to assert on the field's own CELL, not the row. Fourth data-dependent test found in two days and the second whose data is the PMO's own writing

+- [TASK-226] next action · V4 PASS 2026-08-30 with four RESULT corrections in flight; evidence/2026-08/TASK-226-v4-review.md. The conclusion was ruled POSITIVELY ESTABLISHED, not merely fitted: the reviewer checked the epoch arithmetic two ways with no timezone slip, confirmed both readings from the transcript itself (10:24:19.530Z and 10:30:42.309Z, next user prompt 10:25:13.205Z — 2.2s after the shell command), enumerated every agent event in the window with nothing left over, and replicated the byte-for-byte reproduction from scratch to md5 ff66fbf343266a0f339fc48df8b0cd44. THE REVIEW'S OWN FINDING, now TASK-241: the RESULT files a misparse class as 'inert, never affects a verdict' and three of it are NOT — a backticked, indented or fenced path cell parses to a plain key because read_conformance strips backticks, which flips a real file undeclared to conformant and lets the next legitimate declare LAUNDER the decorated row into a canonical one, on the file that gates every write under enforce. It did not cause this row: the elimination rests on the render fixed-point check, which the reviewer reproduced and calls a complete detector for the whole class. So the conclusion is safe and the argument offered for it was not. CORRECTIONS SENT BACK: 'eliminated by experiment rather than by grep' is overstated (row 11 is a grep); 'no other file names CONFORMANCE_FILE' is false (bin/perry-lint:3512 does, read-only, conclusion survives); 'no other input produces it' is false; the lesson has no procedure attached and outranks the RESULT's own better root cause — no actor column, date-only timestamps, and perry-conform never writes events.jsonl, all three verified; and the reproduction recipe no longer replays against the current install because TASK-235 merged at 00:42 and removed DECISIONS.md's schema spec, so it must be run against the skill at 0179c02^. Close at V4 once those land.
+- [TASK-226] review → done · closed · evidence: `evidence/2026-08/TASK-226-v4-review.md` · verification: V4
+- [intake] arrived 2026-08-30 · the 'two runners disagree by 3' figure was carried across four rounds and three briefs before anyone ran it — measured 2026-08-30 on ee0b36a: bash tests/run 2882/3, python3 -m unittest discover -s tests 2882/6 with skipped=4. It is true. But TASK-050 round 8 retracted it as unmeasured, this session's own review briefs asserted it, and it took a row whose deliverable was a RESULT document to actually run the command; a figure everyone repeats and nobody measures is the shape this project exists to catch
+- [TASK-157] in_progress → review · round 2 delivered at 1e0935b; V4 review dispatched
+- [TASK-157] next action · ROUND 2 DELIVERED at 1e0935b, V4 review dispatched. THE INHERITED RESTORE POINT WAS SUBSTANTIVELY WRONG, which is why it was verified rather than merged. TWO DEFECTS FOUND IN IT, both fixed. (1) A GUARD SHIPPED WITH NOTHING HOLDING IT: f15d234 replaced linkage-kr-exists's document scan with TWO questions about the KR id — objective agreement and phase agreement — and tested only the first, because test_a_genuinely_wrong_kr_is_still_reported supplies P001-O9-KR9 whose phase is still 001 and can never reach the phase half. Deleting the phase check left the entire suite's failure set BYTE-FOR-BYTE IDENTICAL. Fixed at 09dcdff with two tests supplying P002-O1-KR1 inside 001-linkage.md with the objective kept at O1, so only the phase half can fire. (2) THE ROW COMMITTED ITS OWN FAILURE MODE: the inherited RESULT claims 'Linked overall KR' was not dropped with the table and its companion says it WAS carried verbatim; both are false for phase 001, where all eight linked: values were copied from the RETRO SCORE TABLE's Measured column. Eight edges to the overall OKR deleted and prose put in their place — P001-O1-KR1's edge to KR-O1.1 became a sentence about parse_tracks returning [('main','project')]. 16 of 24 cells survived at 8abd30d, 24 of 24 after 3784059. The new guard requires every non-empty linked to RESOLVE against perry-goals list --level overall, not shape-match, because KR-O9.9 has the right shape — and refuses to pass on zero values. (3) The inherited RESULT shipped six unsubstituted placeholders, its one real row measured at the wrong commit, '3 pre-existing failures' where it is 5, and '22 rows' where it is 24. SUITE MEASURED FOR THE FIRST TIME: fresh clone at fork point 8abd30d 98/2882/5; f15d234 99/2910/5 — the SAME five; branch head 99/2913/5. discover gives 8, the extra three being test_risks_store's double-import artefact. The branch adds no failure and removes none. Twelve mutations all reddening named tests, with a harness that ASSERTS THE TARGET IS GREEN BEFORE MUTATING — which caught a meaningless red where test_cadence.py's 'from gate import GATE_OFF' only resolves under discover, so a bare-module run reports unittest.loader._FailedTest as if the mutation had worked. MERGE NOTE: main has moved 20 commits past 8abd30d and touches 7 of this branch's files; the author deliberately did not merge because that would change the tree every number was taken on. Correct call. Merge after the verdict.
+- [intake] arrived 2026-08-30 · tests/test_intake_store.py's test_a_row_deleted_by_hand_reports_every_row_it_renumbered builds the exact dangerous precondition — a ## Intake row deleted by hand against a minted store — and then runs only perry-lint, so NOTHING in the whole suite ever runs a shrink-permitted command on that board; the state was constructed and then not used, which is one line short of catching the entire TASK-203 round 4 defect class. A test that builds the dangerous state and asserts something safe about it is worse than no test, because it reads as coverage — sweep for the same shape elsewhere
+- [TASK-203] in_progress → review · round 5 delivered at ab24b45; V4 review dispatched to a fresh reviewer
+- [TASK-203] next action · ROUND 5 DELIVERED at ab24b45, V4 review dispatched to a FRESH reviewer (not the one that found the fifth door). THE BOUND: SHRINK_ALLOWED, a bare frozenset of three names, became SHRINK_ALLOWANCE, a map from each removal command to the count it DECLARES removing — purge 1, resolve-intake 0, intake-sweep the event's own swept count which cmd_intake_sweep already carried. The gate is 'if before - after <= declared_removal(event): return'. Still one question about two integers, not 'may this command shrink' but 'is the drop the drop the caller declared'; nothing is asked about the board, the shape, or when the gate is read, so option A stays rejected and stays unnecessary. Two design points beyond the arithmetic: refuse_to_shrink now takes the EVENT rather than the event name, so the bound is computed inside and no call site can carry the permission without the number; and declared_removal FAILS CLOSED — an unnamed command declares 0, and a listed command whose count is missing, negative, a bool or not an int declares 0 too. BOTH DOORS CLOSED, side by side on this repository's own data against a git archive of afb3a48: resolve-intake was rc 0 / 30 records to 4 / lint '0 drifted' and is now rc 1 / md5 unchanged / lint '26 drifted'; intake-sweep was rc 0 'wrote 1 row(s)' / to 3 records and is now rc 1 / md5 unchanged / lint '27 drifted'. The register still works — on an in-sync copy the whole lifecycle runs, discharge 30 to 30, sweep 30 to 29, new intake 29 to 30, lint clean. THE DECISIVE NUMBER: the previous reviewer's own mutation MR now reddens test_resolve_intake_may_not_shrink_a_store_it_removes_nothing_from, a named BEHAVIOURAL test on a drifted board, where under round 4 it reddened only two assertions about the constant. Every test in TestTheExemptionIsBounded asserts the drift as a CONTROL before any behaviour, so a clean-board version fails its own control. THE SUITE GAP IS CLOSED at 0cc3889 — the dangerous state is now shared by both tests and test_a_shrink_permitted_command_on_that_same_board_is_refused was added; MB1b confirms it is red under round 4's rule. 13 mutations, md5-verified; MB6 (purge 1 to 0) reddens 21 named tests, 16 in test_purge; M6, round 3's consecutive-only weakening, is still red. SPEC ITEM 5 FINALLY COMPLETED AND PROVEN: discover gives 2928 / failures=6, and the same run on the afb3a48 copy gives 2921 / 6 — the identical six — so the three extras over tests/run are pre-existing test_risks_store module-identity failures rather than anything this branch did.
+- [TASK-230] next action · RESUMED 2026-08-30 to verify and finish. Inherits 23e6197, a PMO restore point and not a delivery: tests/parallel rewritten (+160/-25), a new tests/durations.json and a new tests/test_parallel_runner.py, with NO RESULT, no mutation record and no verified baseline. The agent is told to treat it as a hypothesis and audit it — the same situation on TASK-157 tonight found the inherited work substantively wrong in two ways, including eight KR edges silently destroyed. THE BAR THAT MATTERS MORE THAN SPEED, and it is not close: every reduction in wall-clock must be SHOWN not to reduce coverage, with at least three sped-up tests each proved still red when its subject is reverted; no test deleted or skipped to make a number go down; and if the change alters which tests run under which runner, that must be said loudly, because the two runners already disagree here and that has produced three wrong readings in two days. The known flakes are DATA for the row, not work: if the change makes flakiness better or worse that is a first-class result, and a suite that is faster and flakier is not an improvement. Baselines handed over so it compares against real numbers: main on a git archive copy 98/2882/3; main on a LIVE-board tree 5, the two extra being test_contract_key_parity's data-dependent witness tests; discover on an archive copy 2882/6, the three extras being test_risks_store module-identity failures proven pre-existing tonight by running two commits and getting the identical six.

+- [TASK-157] next action · V4 PASS 2026-08-30; evidence/2026-08/TASK-157-v4-review.md. One non-blocking fix in flight, then merge. BOTH AUDIT CLAIMS CONFIRMED BY THE REVIEWER'S OWN MEASUREMENT, not accepted: it exported f15d234 twice, deleted the 7-line phase check from one, ran the suite on both — 99 modules / 2910 tests each and the failure sets diff IDENTICAL — then showed the fix cuts the other way, since at head the same deletion reddens only the two new tests while test_a_genuinely_wrong_kr_is_still_reported stays green, which proves that test cannot reach the phase half. Claim 2 exact: at f15d234 all eight linked: values are verbatim the retro Measured column; at head they are byte-identical to the Linked overall KR column at 8abd30d, 16 of 24 cells before and 24 of 24 after. It re-measured the duplication with its own scanner and got 24 rows / 24 title diffs / 24 metric diffs — the branch's number is right and the SPEC's 22 was not. All twelve mutations re-run rather than the five asked for, green-first and md5-restored, with diff -r showing no residue. Every guard on the branch reddens a named test when deleted. THE FINDING, same shape as Claim 2 displaced into the future: goals/state/linkage_TEMPLATE.md was not updated with the rest of plan-phase — no linked: slot, and its placeholder still reads 'metric as written in the phase file', pointing the next author at a file that no longer holds it. Being fixed in this row because the template is plan-phase's own artefact. The separate weakness it exposes — the guard's checked >= 8 is satisfied by phases 001 and 003 alone, so a phase 004 with every linked: empty passes untouched — is TASK-242, deliberately not widened here.
+- [TASK-157] next action · V4 PASS with the template fix applied at aab4186; merging once the merge-probe suite reports. THE TEMPLATE IS CLOSED: goals/state/linkage_TEMPLATE.md — the file an author writes the register FROM — now carries a linked: slot on all three KR stubs, with a comment saying it is an id and not prose and naming the phase-001 mistake that made the point; the metric: placeholder reads 'metric, as prose — always safe to display' instead of pointing at the phase file; linked is in the template's own field table with the rule that it must resolve to an overall KR OKR.md declares. ONE MORE STALENESS FOUND OUTSIDE THE SCOPE LINE AND FLAGGED AS SUCH: goals/reference/linkage.md:128 described perry-lint as checking 'every KR id present in the phase file', which has been false since f15d234 replaced that scan with the two id questions. Corrected, and the agent said explicitly it was one line past the scope it was given — a documented check that no longer existed. M13 and M14 each redden the same named test alone, green-first and md5-restored; fourteen mutations on this row now. A WRINKLE WORTH KEEPING: the first version of that test asserted 'as written in the phase file' not in text over the WHOLE FILE, and went red on the agent's own comment quoting the removed placeholder to explain why it is gone — a substring test over a file reads the explanation as the defect it explains. Now it reads the metric: value lines only. Same family as the test_board_render prose defect filed tonight. RECORDED NOT FIXED: the guard proves some phase has overall edges rather than that the newest one does (TASK-242); and aiMark and every external consumer are unrun by both this round and the reviewer — perry-state --json keeps its key shape and kr_total, but metric now carries the register's wording, longer than the document's cell on 22 of 24 KRs, so a pinned consumer sees no structural break and an unmeasured rendering change. bash tests/run at head: 99 modules / 2914 tests / the same five pre-existing.

+- [TASK-050] next action · ROUND 9 DELIVERED at b5e7be3, V4 review dispatched to a FRESH reviewer. THE SHAPE NET IS DELETED, and with it ROW_NAMES, the second name allowlist, _local_folders, FOLDING_METHODS, _string_constants and the .split('|') row inference that produced round 8's false positive. NO ALLOWLIST OF VARIABLE NAMES SURVIVES ANYWHERE — grep ROW_NAMES returns four prose lines saying it was deleted and no code; what remains is BLESSED/THE_RULE/ROW_PRODUCERS (function names, which are the design), ITERABLE_WRAPPERS (builtins), NOT_A_READER (four directories each with a reason) and inline str method names for following a value through a chain, all tabulated so they can be checked rather than believed. THE COST IS MEASURED, NOT DESCRIBED, and it is what the review turns on: DRIFT 24 of 24 caught, CLEAN 0 of 12 falsely flagged where round 8 was 1 of 8, and SECOND_RULE 0 of 41 caught. That last is the class where a reader invents a NEW folding rule that never calls squash at all, which a symbol check cannot see by construction — the reviewer is asked to rule explicitly on whether that gap is what option C ACCEPTS BY DESIGN or means the row does not close, and to argue it rather than wave it through in either direction. The author's supporting argument, also to be checked: round 8's declared false positive was on code the repository ALREADY FORBIDS, since test_row_integrity's test_no_tool_splits_a_row_on_a_raw_pipe reports a bare .split('|') anywhere in bin/ and viewer/, receiver-blind — so keeping the shape net bought nothing. TWO MORE LIVE SITES ROUND 8 LEFT, now converted and mutation-tested: bin/perry-lint:339 re-folded a key header_index had already produced, and bin/perry-task:1339 re-folded keys.raw. THE CORPUS IS REBUILT from the round 4/5/7 review prose with every entry quoting its source line and label and path uniqueness asserted AND mutation-tested — round 8's pruning was invisible because plant labels were re-used for different shapes. BOTH CARRIED FIGURES SETTLED: discover differs from tests/run by exactly 3 on three trees, the three being test_risks_store; and the call-site count is 58 on 68e63cf (round 8's table was right, its 67 was not), 59 on round 9. Ten mutations all md5-restored and all reddening a named test; R9-9 puts the pipe inference back and turns test_each_clean_shape_is_left_alone red, so criterion 4 holds as a consequence of the design. Baselines: tests/run main@6c0d041 98/2882/3 and round 9 99/2895/3, same three names; discover 2882/6, 2893/6, 2895/6.

Two RESULT corrections in flight, then merge — the merge onto main was already probed clean with both sides' modules green (evidence/2026-08/TASK-203-merge-probe.md). THE BOUND CLOSES THE FIFTH DOOR, measured on a cp -R of the live board with 32 intake records and 28 rows tidied off by hand: afb3a48 gives rc 0 and 14328 bytes / 32 records to 1420 / 4 with lint saying '0 row(s) drifted'; the tip refuses at rc 1, md5 unchanged, lint '28 row(s) drifted'. Same for intake-sweep, which declared 1 and removed 27. The register still works — discharge 32 to 32, sweep 32 to 31, new intake 31 to 32, lint clean. THE DECISIVE CLAIM HELD AND GOT BETTER: MR now reddens THREE tests, two behavioural on drifted boards, where under round 4 it reddened only two assertions about a constant. The reviewer also mutated SEVEN GUARDS THE AUTHOR NEVER TOUCHED — each sub-clause of the count check, the message branch, the shape early-return, the carry-forward per-row clause — and every one dies under its own deletion. declared_removal fails closed on all five shapes including bool. Spec item 5 genuinely closed: discover 2929/6 at the tip and 2921/6 on the afb3a48 copy, the identical six. TWO CORRECTIONS SENT BACK: the RESULT's claim that a clean-board version of each bounded test 'fails its own control' is OVERSTATED, because drifted([1,2,3,4]) passes all three controls and nothing asserts len(keep) < 4 — the tests still go red on the behaviour assertion so nothing is green for the wrong reason, and one assertLess makes the sentence true; and the 'tree layout' explanation for the discover discrepancy is unsupported, because the reviewer ran discover on both a worktree copy and a git archive extraction and got the author's figures on BOTH. THE REVIEWER'S OWN FINDING is filed as TASK-243, non-blocking by its own reasoning: a count-preserving substitution destroys canonical records silently and the drift report goes DOWN as it happens.
+- [TASK-203] next action · V4 PASS with both corrections applied at 65f93ef; merging once the merge-probe suite reports. bin/perry-task's md5 is UNCHANGED from the reviewed tip — neither correction touched the bound. CORRECTION 1, the control now controls: drifted() asserted three things and compared none of them to each other, so drifted([1,2,3,4]) sailed through; one assertLess(rows, records) in the shared control now fires with a message saying the board must hold FEWER rows than the store or no shrink is possible and the test cannot tell whether the bound fired — which is exactly how round 4's clean-board test passed with the allowance and without it. The RESULT says the sentence WAS overstated and that the assertion is what made it true, rather than quietly reading as if it always was, framed as 'a control that cannot fail is the same mistake as a test that cannot fail, one level up'. MB1c re-ran the bound-removal mutation after the change and the SAME SEVEN named tests go red with the md5 unchanged — the tightened control changed the mutation evidence not at all, which is what a control that is not part of the subject should do. CORRECTION 2: the tree-layout attribution is struck, replaced by the reviewer's measurement that discover gives the author's figures on BOTH a worktree copy and a git archive extraction, so layout is not the cause and the cause is UNKNOWN — recorded as unexplained. ALSO RECORDED: the zh bounded refusal is logged as verified BY THE REVIEW, explicitly weaker provenance than verified here and explicitly not the same as untested; and a new section 8 names the count-preserving substitution as the door this bound does NOT close, with the reviewer's numbers, so nobody reads the before/after tables as 'the intake store can no longer be corrupted at rc 0'. The bound closes the shrink, not the swap. Final baseline at 0ef1576: 99 modules / 2929 tests / 3 failures, same red set; the added assertion introduced no test.

+- [TASK-230] next action · DELIVERED at e685c6b, V4 review dispatched. THIRD AUDIT OF A RESCUED RESTORE POINT TONIGHT, AND THE THIRD TO FIND REAL DEFECTS. (1) THE INHERITED --ids SET SILENTLY DROPPED 14 TESTS — parse_ids required unittest's verdict at the end of the line naming the test, and it is not there whenever a test writes to stderr, because unittest prints ' ... ' when the test STARTS so the output lands in between and the verdict is pushed onto its own line. Measured live: unittest ran 2899, the parser accounted for 2885, fourteen missing across seven modules, all lost to ordinary DeprecationWarning lines. The function whose whole job is to say which tests ran was 99.5% right. Fixed, and --ids now REFUSES to write a file whose count disagrees with unittest's Ran N — two numbers of independent origin. (2) The inherited docstring's headline measurements were not reproducible — it claimed 446.3s to 322.1s and per-module costs of 322/282/234s, while tests/durations.json committed in the same change disagreed by 2x. Replaced with twelve runs and their conditions. WHAT HOLDS: load-controlled A/B, both schedules scored against each run's own per-module costs, alphabetical 179.7/222.9/241.1/210.4 to longest-first 120.1/140.0/155.4/133.1 — a 33-37% saving, equal to the perfect-knowledge schedule in 3 of 4 runs, with the simulation reproducing each measured wall to within 0.1s four times of four. Total CPU unchanged at ~500s vs ~480s, so it is scheduling and not lost work. THE SAFETY CLAIM: serial and parallel id sets are 2904 = 2904, ZERO on either side, and twelve full runs gave twelve identical id sets where the spec asked for five. WHAT DOES NOT HOLD, all self-reported: the spec's 'under two minutes' is NOT reachable by this approach, because the floor is one module — test_task_writer.py runs alone for 105-149s and no worker count moves it, filed as TASK-244; flakiness effect DECLINED rather than claimed, since test_host_support's race fired 1 of 12 and that is not a difference, with a plausible mechanism named for it getting worse; the machine was never quiet, foreign load 17-65 all night with the identical command taking 133.1s and 285.0s; and the branch is 65 commits behind main, merge expected clean but expected rather than verified. CORROBORATION WORTH KEEPING: the test_contract_key_parity witness pair flipped ok to FAIL at ~01:55 and stayed, INCLUDING across two alphabetical runs — which is what rules the schedule out as the cause and independently confirms the data-dependence finding filed tonight. Also self-reported: one use of git checkout -- early, on its own throwaway diagnostic edit, which review-constraints forbids; everything after used explicit cp and md5.
+- [TASK-050] review → in_progress · V4 round 9 FAIL — the fix is ~5 lines; round 10 dispatched
+- [TASK-050] next action · V4 ROUND 9: FAIL 2026-08-30, evidence/2026-08/TASK-050-round9-v4-review.md — but the reviewer ruled the round's CORE CORRECT and the fix is about five lines. THE QUESTION THE ROUND TURNED ON WAS RULED IN THE ROUND'S FAVOUR: 0 of 41 on SECOND_RULE is ACCEPTABLE under option C, because detecting a from-scratch fold IS source-expression recognition and failing on it would order the very thing USER-904 rejected. Measured, not argued: R9-9 reproduces exactly, so 41-of-41 and 0-of-12 cannot both be had; and the second-rule class is covered DYNAMICALLY — reverting parsers.py:1833 reddens test_every_decorated_header_cell_reached_header_index, and so did the reviewer's own value-identical alias fold at that site. THE FAIL IS THE COROLLARY: with the shape net gone the drift half carries the whole static claim, and it recognises the rule by the FUNCTION'S NAME rather than the symbol. _RowLocals resolves the two HARDER indirections the corpus plants — def fold(s): return squash(s), and fold = lambda s: squash(s) — and misses the one-liner: fold = squash, from tables import squash as fold, and import tables; fold = tables.squash all escape. This repository's own idiom is the escaping form: bin/perry-lint:250 is literally 'norm = squash', seen today only because norm happens to be in BLESSED. D06 shows the author handled import aliasing ONTO A BLESSED NAME; the case landing anywhere else is neither planted nor handled. Planted into bin/perry-tasks — the one converted reader the round itself says the watch does not drive — offenders_by_symbol goes to [], all three header modules OK, row-integrity OK, and the full suite stays at 99 modules / 2895 tests / the same three pre-existing failures. It is DRIFT, not SECOND_RULE, so the declared limit does not cover it, and it is in none of the nine limits section 6 declares. WHAT THE REVIEWER VERIFIED RATHER THAN ACCEPTED: the worktree byte-identical to its commit across 688 re-hashed blobs at start and end, so the hand restore is clean; no variable-name allowlist anywhere; header_index the only header-cell fold, by its own AST enumeration of all 39 squash/norm calls each classified by reading; both live conversions real and exact with no third site; ALL TEN mutations reproducing; the corpus rebuilt independently from rounds 4/5/7 with NO PRUNING FOUND; test_row_integrity's reach real, so the argument for deleting the shape net holds; and round 8's retraction now complete. THREE MINOR: corpus D20 says 'no shebang' but _plant prepends one unconditionally so it cannot discriminate the hole it names; Watch.__enter__'s rebinding loop survives its own deletion with all 7 tests green, contradicting its own comment; grep ROW_NAMES returns two prose lines, not the four claimed.
+- [TASK-230] next action · V4 PASS 2026-08-30; evidence/2026-08/TASK-230-v4-review.md. Four RESULT corrections in flight, then merge. THE SAFETY CLAIM WAS VERIFIED BY A METHOD THE AUTHOR DID NOT USE: the reviewer enumerated test ids with unittest's LOADER — never runs a test, never calls parse_ids — for whole-suite discover and for the per-module partition the runner executes, in separate processes: 2907 vs 2907, zero on either side. That reference set then matched id for id against its own re-implementation of the parser over the author's raw serial.err (2904), all twelve of the author's --ids files (2904 each, all twelve pairwise identical), and its own fresh tests/parallel --ids run (2907). The speedup is scheduling. The audit is confirmed on a DIFFERENT corpus: old parser 2890 against unittest's Ran 2904, missing across the same seven modules with the same distribution, and the refusal fires end-to-end at rc=1 with no file written. ONE REAL DEFECT, non-blocking, sent back: main()'s --ids refusal SURVIVES ITS OWN DELETION — if short: to if False: leaves the whole suite green, because unaccounted() is unit-tested and its USE is not. The RESULT says a unit test 'cannot give' that coverage, which is wrong: it is a run_module monkeypatch away. Non-blocking because main() has never had coverage, the refusal demonstrably fires, and it is not the gate. THREE OVERSTATEMENTS also sent back: 'the model is exact, four times of four' is oversold, since two of the four are arithmetic identities where makespan equals the longest module's own measured time, so the simulation is validated by TWO; an md5 in section 6 matches no committed version of tests/parallel; and the docstring quotes 133-150s while omitting the author's own 247s and 285s runs. The branch is 66 behind main, not 65. ALL FOUR LIMITS RULED NON-BLOCKING, and one with a finding: the two-minute target is structurally unreachable AND THE SPEC CONTRADICTS ITSELF, because it forbids sharding below the file while asking for a number only sharding can reach — the reviewer's own run ended 0.1s after test_task_writer.py did, 246.74s of 246.8s. Declining the flakiness claim on 1-of-7 vs 0-of-5 is correct. The git checkout -- does not matter and reporting it was right. The reviewer extended the mutation sweep to thirteen covering every production surface the new tests touch: all 25 tests die under at least one, and the main() refusal is the only survivor.

+- [TASK-244] next action · Blocked until TASK-230 lands. PREMISE CORRECTED 2026-08-30 by TASK-230's own post-review measurement — read this before starting, because the row was filed on a number that has since moved. On a QUIET machine bash tests/run on the corrected tree is 108.9s, UNDER the two-minute target, red on exactly the same five tests, with CPU identical to a 266.7s run (341.1s user + 157.0s sys against 338.6s + 153.9s) — identical work, less than half the wall. A follow-up --times run took 126.3s while test_task_writer.py took 126.28s: the suite finished 0.02 SECONDS after its longest module, which independently reproduces the reviewer's 246.74-of-246.8 observation. So the floor is real and the schedule is optimal — 'optimal is one module long' — but the target is NOT structurally unreachable the way this row was filed. It is reachable on a quiet machine and unreachable on a loaded one, and the module's own 105-149s is the whole margin. That changes what this row is for: not 'get under two minutes', which the machine already does when it is idle, but 'stop one module owning the floor', so the number holds under the load this project actually runs at. TASK-230's spec-contradiction finding still stands — the spec asks for a number only sharding can guarantee while forbidding sharding below the file — and correcting that wording is part of this row.
+- [TASK-230] next action · V4 PASS with all four corrections applied at eb75dbe; merging once the merge-probe suite reports. THE GUARD IS FIXED, NOT EXPLAINED AWAY: main() is now driven directly with run_module stubbed, and the refusal gets THREE mutations rather than one because it is two independently deletable lines plus the direction where a guard gets 'fixed' into refusing everything — M6 'if short:' to 'if False:' (the reviewer's own), M7 'if args.ids and short:' to 'if False:', M8 'if short:' to 'if True:', all three red, tree md5-restored. The original error is KEPT in the RESULT rather than deleted, because the untestability claim was load-bearing for shipping an uncovered guard. 'FOUR TIMES OF FOUR' IS NOW TWO, with the reasoning: the two longest-first runs are arithmetic identities where the longest module starts at t=0 and the simulated makespan restates that module back at itself; only the two ALPHABETICAL runs predict anything, and they landed 179.7 against 179.8 and 241.1 against 241.1. The md5 is replaced by an end-to-end proof re-run against the committed state, and the published range becomes 133-285s median 149.7s — the author's note is that the reviewer's 246.8s run was inside the honest range and outside the published one, which was 'the same optimism I had just finished criticising in the inherited docstring'. TWO THINGS AFTER THE REVIEW. The machine went quiet: 108.9s, UNDER the two-minute target, same five reds, CPU identical to a 266.7s run — and a --times run finished 0.02s after test_task_writer.py's own 126.28s, reproducing the reviewer's 246.74-of-246.8. TASK-244's premise is corrected accordingly. AND THE FLAKE FIRED AGAIN WITH A WORSE COUNT: test_host_support is 2 of 10 longest-first against 0 of 5 alphabetical, not the 1-of-7 published. The author still declines to claim an effect but records that publishing the stale ratio because it read better is the failure this row exists to catch — and notes the second occurrence fired at load 5.76, which cuts AGAINST the contention mechanism it had volunteered. Recorded as evidence against its own story.

The fence mechanism is a naive boolean toggle flipped by ANY fence-looking line, not CommonMark's rule that a fence closes only on the same delimiter char with a run length >= the opener and nothing after. So a NESTED fence — the ordinary way markdown shows a fenced block — flips the toggle off and the row inside is read as a real declaration again. Measured on a git archive copy of 8c34973 with the branch's own perry-conform: plain fence gives undeclared/unreadable=1, while a tilde fence wrapping a backtick fence, a 4-backtick fence containing a 3-backtick line, and a backtick fence wrapping a tilde fence ALL give conformant/unreadable=0 — and the LAUNDERING comes back with them, so a legitimate declare of a different file rewrites the record to contain the decorated row as a plain canonical one. The author declared this in section 8 as 'did not verify a nested fence'; declaring it does not discharge it, because it IS the deliverable's third named shape. The reviewer sketched CommonMark's rule in a throwaway copy: ~10 lines inside the same function closes all four with the 71 tests in both touched modules still green. SECOND FINDING: 'except UnrenderableCell: canonical = None' survives its own deletion, so section 4's 'nothing I wrote can be deleted with the suite unchanged' is FALSE — and it is reachable (a U+2028 in a path cell, because read_conformance splits on \n while line_break_at uses splitlines()'s eleven boundaries) and load-bearing, since without it perry-conform status dies with an unhandled traceback. A THIRD FRAMING the reviewer offers and neither agent found: require the row to be in the contiguous run following the '| File | ... |' header — no HEADER prose, no fence bookkeeping, and immune to this defect. Round 2 is told to evaluate it honestly against CommonMark's rule and say which it chose. EVERYTHING ELSE REPRODUCED EXACTLY, including all seven mutations, the M1-vs-M2/M3 disjointness, the controls proved able to fail, and both archive baselines; and all five declared limits were ruled, with silently deleting an unreadable row ruled ACCEPTABLE TO SHIP and the author right both not to fix it and not to file it.

ALIAS FORMS NOW RESOLVE: _RowLocals builds a per-file map from local name to the BLESSED name it IS, over three binding shapes run to a fixpoint, and _blessed_calls plus the scalar half ask that instead of the module constants. Each form pinned to its OWN mutation, several reddening exactly one corpus entry: 'from tables import squash as fold' reddens D26 only, 'fold = tables.squash' reddens D27 only, the scalar call reddens D28 only, the out-of-order chain reddens D30 only. LIVE DEMONSTRATION R10-11: renaming the repository's own idiom on a live reader — keyof = squash at bin/perry-lint:250 plus value = keyof(key) at :348 — is now reported as 'bin/perry-lint:349: keyof(key)' and reddens three named tests, while the identical plant against round 9's own header_rule.py returns []. The live tree still has offenders_by_symbol('.') == [] and exactly one alias in the whole repository, bin/perry-lint norm to squash, already blessed. Corpus DRIFT 24 to 33 all caught, CLEAN 12 with 0 flagged, SECOND_RULE 0 of 41 unchanged. IT CORRECTS THE REVIEWER, MEASURED: the reviewer's fix does not close the reviewer's own end-to-end case, because that bin/perry-tasks plant crosses TWO independent holes. The alias is one. The other is '_hdr = perry_store.intake_table(board, ops)["header"]' — a row produced in ANOTHER MODULE and carried through a dict key, which a file-local walk cannot see; the same plant written with a bare squash and no alias at all escapes round 9's tree identically. Closing that statically would be interprocedural source recognition, the option the amendment rejects by name. So it was closed through the design's other half: bin/perry-tasks is now DRIVEN by the runtime watch, which was round 9's own declared limit and the reason the reviewer chose that file. R10-10 replays the plant verbatim and the runtime test goes RED while offenders_by_symbol still returns []. Both facts are in the result. TWO GREEN MUTATIONS REPORTED AS FINDINGS: R10-4 and R10-5 came back green first time, because the fixpoint was dead weight (D30's chain was in-order and ast.walk is breadth-first) and every alias entry was redundantly caught by the scalar half; D30 was re-planted out of order and D32/D33 added, after which both mutations redden exactly the intended entries. THREE MINOR CLOSED, with D20 fixed on the PLANT side and the regression check exactly as asked — R10-7 now reddens D20 AND D21 where R9-6 reddened D21 alone. NOT CLOSED: the cross-module row source, stated as a limit and covered only by the runtime watch and only for readers a parse reaches — every converted reader is driven today, so the uncovered set is empty NOW and one unwatched conversion away from not being; three alias shapes (container rebinding, a function returning the rule, a binding in another module); and section 7 restates the limits from scratch at 13, versus round 9's nine, because the review found one that was in none of them.

THE FAIL: bin/perry-state still asks 'is there a .perry/config.md' as its test for 'is this configured' in TWO places — :2022, the installed gate, and :2607, its own project-root walk, which is a BYTE-FOR-BYTE DUPLICATE of the walk that WAS converted in bin/perry-lint main and viewer/parsers.py _resolve_project_root. Reproduced on the branch tip with the markdown deleted and the store untouched, same tree, same cwd, same PERRY_HOME: perry-lint walks up and finds the project, and perry-state --json does not — it reports 'No Perry state found — run /perry for first-time setup', WHICH IS THE EXACT STRING THE AUTHOR QUOTES as the defect that justified converting resolve_state_root. The row's own fix justification still reproduces one file over. Second site with --root given so the walk is out of play: a project configured by the STORE alone reads installed:false while the same project configured by the MARKDOWN alone reads true. WHY IT BLOCKS, and it is not the reach — the reach is narrow, needing cwd != project root: the row serves a KR that COUNTS CALL SITES IN bin/, the missed sites are in the file the spec names first, and the RESULT ASSERTS COMPLETENESS rather than declaring a gap. The author's own declared grep finds both in one command. Declared gap 4 was honest and does not block; the FAIL is a DIFFERENT sentence in section 4, which says the four converted sites 'were the rest'. WHAT THE REVIEWER CONFIRMED INDEPENDENTLY: the third-reader call was CORRECT and not scope creep — reproduced on main at 658e8c9, so the spec's own V4 step 1 was unsatisfiable as written; the placement and the _validated_config_records delegate are behaviour-preserving; the md5 reproduced on both sides of the rebuild; the 29 prose lines verbatim; the harness's '>=1 test selected' assertion real; all 38 tests in the new module reddened, with the mutations 28-of-28 red on the reviewer's own driver against a clean clone. All five declared gaps ruled non-blocking. TWO NUMBER CORRECTIONS: the mutation table has 28 rows, not the 27 the text claims; and the reviewer measured 100/2992/3 to 101/3031/the same 3, getting a third data-dependent test_diagnose failure the author did not, red on both sides. ONE MINOR: mutation X4, dropping the store-default versus store distinction in config_store_settings, leaves all 38 green — a documented reason value with no guard.
+- [TASK-050] review → in_progress · V4 round 10 FAIL — the mechanism was ruled correct; the remainder must be measured. Round 11 dispatched
+- [TASK-050] next action · V4 ROUND 10: FAIL 2026-08-30, evidence/2026-08/TASK-050-round10-v4-review.md — and THE RULING THIS REVIEW EXISTED TO MAKE WENT THE ROUND'S WAY: closing a static hole with a runtime watch DOES satisfy the amendment, because nothing in it requires a static check, its verification is stated as 'reverting reddens a NAMED test', and round 9's accepted 0-of-41 already rests on a dynamic cover. THE FAIL IS THE SENTENCE AFTER IT: a dynamic cover discharges a static hole only if the round MEASURES which sites it reaches and STATES the remainder — and this round states the remainder as EMPTY when it is TWELVE. Three things, none a redesign. (1) A DICT-CARRIED HEADER ROW ESCAPES BOTH HALVES, and it is NOT interprocedural as section 7 limit 1 claims: one line in bin/perry_store.py risk_plan, which already reads header, keys = table['header'], table['keys'], gives offenders_by_symbol == [] with all three header modules OK and the full suite at the same three failures. It escapes with NO MODULE BOUNDARY AT ALL — t = {'header': split_row(line)} then [squash(c) for c in t['header']] is local dataflow in one function, resolvable by the same _RowLocals machinery that already resolves aliases. And ['header'] is this repository's own idiom. (2) THE UNCOVERED SET IS NOT EMPTY: 17 live dict-key header reads, 12 in functions the watch never reaches; WATCHED is 16 functions against 45 holding the 59 call sites. Round 11 must COMPUTE the remainder and print the number and the list, not assert it. (3) WATCHED IS A GUARD THAT SURVIVES ITS OWN DELETION — removing an entry leaves all 8 tests green, and it is the mechanism the dynamic cover depends on. Also no DRIFT corpus entry plants a dict- or attribute-carried row, which the reviewer calls the same structure as round 9's charge with a different noun. RULED FOR THE AUTHOR: the bare-squash claim is TRUE, reproduced in all three spellings, so round 9's prescribed fix could not have closed its own demonstration and the framing was not a rationalisation; round 9's actual charge is FULLY CLOSED with 10 alias shapes caught; every mutation verified including R10-7 reddening D20 AND D21; the fixpoint now earns its place; 'exactly one alias' confirmed by the reviewer's own repo-wide AST sweep; the corpus's nine new entries all traceable and NONE INVENTED TO BE EASY; the tree matching its commit across 721 blobs; and baselines matching the PMO's merged-tree numbers exactly. MINOR: R10-2 reddens eight entries, not the six section 3.1 lists.

Same defect class as the two sites TASK-233 closed in bin/perry-state: a project configured by the store alone is read as unconfigured. → Declared as a COUNT by TASK-233 round 2 on 2026-08-30 rather than folded into a sweep claim — which is the distinction round 1 was failed for — and confirmed independently by its V4 reviewer, which also named a third site the author's grep shape did not surface. The re-run grep over bin/ and viewer/ for EXISTENCE checks returns five hits: viewer/parsers.py:401 is the predicate itself, bin/perry-goals:2177 already asks the wide form, bin/perry-lint:637 is TASK-095's class, and bin/perry-diagnose:1373 and :2501 still ask the narrow way. The reviewer added bin/perry-migrate:228, where board_language() returns 'en' the moment .perry/config.md is absent — so a project configured by the store alone migrates into English regardless of what its store says. perry-diagnose was not converted because it does not import parsers, making it an import change plus two guards. THE REVIEWER MADE THIS ROW A CONDITION OF ITS PASS: 'the two bin/perry-diagnose sites and bin/perry-migrate:228 exist only in this report. If they are not filed as a row, the count becomes evidence nobody is counting.'
+- [TASK-247] next action · Blocked until TASK-233 lands. THREE sites, not two — the third came from TASK-233 round 2's reviewer: bin/perry-migrate:228 board_language() returns 'en' as soon as .perry/config.md is absent, so a store-only project migrates into English no matter what its store declares. That one differs from the other two: it is not an 'installed' question but a LANGUAGE default, and getting it wrong writes a board in the wrong language rather than reporting a project as unconfigured. Start from evidence/2026-08/TASK-233-round2-v4-review.md and evidence/2026-08/TASK-233-result.md, which carry the grep and the classification of every hit. TASK-233 round 2 proved by cross-check that its own two sites fail under DIFFERENT conditions and that one test covering both would have been a false guard — assume the same here until measured otherwise, and give each of the three its own named test and its own mutation.

THE RULING THE ROUND ASKED FOR: the contiguous-run rejection STANDS, and the reviewer established it the hard way — it BUILT the framing itself from round 1's own sentence, into its own copy, never having seen the author's prototype, and probed it against its own 22-shape catalogue. The author's measurement reproduces exactly. It added two things the RESULT does not say, and both strengthen the rejection: it would have been a REGRESSION rather than merely a non-fix, because shape 15, the whole table in a plain unnested fence, is already closed by round 1's broken toggle and the contiguous run HANDS IT BACK; and the obvious patch, 'only the first header run counts', is the same all-or-nothing failure section 1 rejects the whole-file fixed point for, reached by document order instead of by a stray line. Round 1's framing had a hole neither that reviewer nor the PMO saw. VERIFIED INDEPENDENTLY: the 21-shape catalogue cell-for-cell across three trees, six flips, nothing regressed, four legitimate rows still declaring, 09 and 12 confirmed fail-open on round 1; all 15 mutations on the reviewer's OWN harness with its own replacement lines, M9 through M13 each reddening exactly one named test, M1 disjoint from M2/M3, M14 reddening at the EXIT-CODE assertion; and the all-or-nothing replacement measured genuinely stronger rather than differently worded — one stray blank line voids all 23 of Perry's real declarations under a whole-file rule and 0 under the per-row rule. Suite on the merged tree 3c5f186: 101 modules / 3036 tests / 3 failures, exactly the PMO's figure, WITH NO FOURTH FAILURE — an eighth non-reproduction of the flake, which does not block. It also ran two checks nobody had: seven 'must still declare after a properly closed fence' shapes with no false refusals, and the human non-JSON status rendering. And it could not run declare, because the brief forbade it, so it COMPUTED what declare writes via render(parse(record)) and said so as a method note rather than claiming the command was exercised. TWO CORRECTIONS SENT BACK: section 9 mentions HTML blocks only in the fence-line direction, which reads as coverage — a bare canonical row inside <pre> or an HTML comment still declares and is still laundered, identically at all three trees, filed as TASK-248; and section 4's 'no clause of the new mechanism can be deleted with the suite unchanged' should say FENCE RULE, since M16/M17 show two other clauses survive weakening with the suite green. That second one is the same shape TASK-233 was failed for tonight, one row over.

+## New tasks added
+
+### TASK-239 — the decide lane is fully ungated under ADR-004 after TASK-235, and the comment that records it says the opposite
+
+- **Owner**: Coding Agent
+- **Priority**: P1
+- **Track / mode**: main / project
+- **Deliverable**: Either the decide lane is gated again under ADR-004 on something that can actually carry a declaration, or ADR-004's posture explicitly exempts a lane whose only artefacts are the ADR bodies themselves — written down as a decision rather than left as a side effect of deleting an index. Whichever it is, perry-decide new on an undeclared project behaves the way the written rule says, and the rule is findable from the lane's own reference page.
+- **Verification**: On a project with nothing declared and PERRY_CONFORMANCE=enforce, perry-decide new does what the written rule says, shown by command and exit code on both an undeclared and a declared project. If the answer is 'exempt', the exemption is cited from the file that states it, and perry-conform's own status output does not imply the lane is covered when it is not. Mutation: revert whichever guard or exemption ships and show a NAMED test goes red — a guard that can be deleted with the suite unchanged does not count. Baselines name the runner AND the tree.
+- **Dependencies**: TASK-235
+- **Out of scope**: Restoring perry/DECISIONS.md. It is deleted by decision, DESIGN-013 User Decision 3, and re-adding an index to give the gate something to hold would be exactly the move section 4.1 forbids. If the only way to gate the lane is an index, that is a finding to report and a decision to escalate, not a thing to do quietly.

+### TASK-240 — an ADR id can be reissued, because perry-decide writes no events and has nothing to retire one with
+
+- **Owner**: Coding Agent
+- **Priority**: P1
+- **Track / mode**: main / project
+- **Deliverable**: The two tools agree, or the disagreement is a written decision rather than an accident. What that means concretely depends on USER-909: under (a) perry-decide writes events like every other writer and retires an id the way perry-task does; under (b) an ADR file may not be removed at all, only superseded, so no id is ever orphaned; under (c) an ADR id is documented as a slot rather than an address and every existing citation is audited for what that costs.
+- **Verification**: Mint an id, delete its file, mint again, and show the outcome the chosen option requires — by command and exit code, on a project with and without unrelated writes in between, because the reviewer proved that gap is where the non-determinism lived. Mutation: revert whichever mechanism ships and show a NAMED test goes red. If the answer is (b), the refusal must name what to do instead, and perry-decide supersede must actually be reachable from it. Baselines name the runner AND the tree.
+- **Dependencies**: USER-909
+- **Out of scope**: Re-adding an index to give the retirement mechanism something to read. DESIGN-013 section 4.1 gave that surface up deliberately and TASK-235 ships a guard that catches it re-added under another name. If the only workable mechanism needs an index, that is a finding to escalate, not a thing to do quietly.

+### TASK-241 — a backticked path in .perry/conformance.md parses to a plain key, so a decorated row can declare a file conformant and the next legitimate declare launders it into a real one
+
+- **Owner**: Coding Agent
+- **Priority**: P1
+- **Track / mode**: main / project
+- **Deliverable**: A decorated row in .perry/conformance.md cannot silently become a declaration. Either the reader refuses a row it cannot round-trip — render(parse(row)) == row, which the reviewer showed is a complete detector for this class — or decoration is stripped only where a documented rule says it may be, and every other shape is reported as unreadable rather than parsed. The existing ConformanceRecord already distinguishes 'unreadable' from 'absent' and from 'declared'; that distinction is the place to put this.
+- **Verification**: Plant each of the three live traps — backticked path, indented row, fenced row — on a copy and show each is REFUSED or REPORTED rather than parsed as a declaration. Then plant one and run a legitimate declare, and show the decorated row is not laundered into a canonical one. Mutation: revert the guard and show a NAMED test goes red for each of the three shapes, not one test covering all three. Confirm the asterisk case still behaves as it does today — a bolded header row was once read as a declaration and squash already answers that; do not regress it. Baselines name the runner AND the tree.
+- **Dependencies**: —
+- **Out of scope**: Converting the file to .perry/conformance.jsonl. That is TASK-234, blocked on TASK-050, and it would dissolve this defect rather than fix it — but this row must not wait on it, because the hole is live under the enforce gate today and TASK-234 has no date.

+### TASK-242 — linkage-kr-exists proves SOME phase has resolvable overall edges, not that THIS phase does
+
+- **Owner**: Coding Agent
+- **Priority**: P2
+- **Track / mode**: main / project
+- **Deliverable**: The check answers a question about the phase in front of it. Concretely: the phase being linted has its own edge coverage asserted, rather than a repository-wide count that older correct phases can satisfy on a new phase's behalf. Whether every KR must carry a linked: value, or only that a phase declares which of its KRs deliberately carry none, is the design question this row settles — and it must be settled, because 'some KRs have no overall edge' is a legitimate state that the current threshold cannot distinguish from 'nobody filled this in'.
+- **Verification**: Author a phase whose linkage register has every linked: empty and show the check reports it — named phase, named KRs. Author one where a KR deliberately carries no edge and show that is NOT reported, or that it is reported differently. Mutation: revert whichever per-phase assertion ships and show a NAMED test goes red on a fixture representing the NEW phase, not on 001 or 003 — a test that passes because an old phase is correct is the defect this row is about. Baselines name the runner AND the tree.
+- **Dependencies**: TASK-157
+- **Out of scope**: goals/state/linkage_TEMPLATE.md's missing linked: slot and its stale metric placeholder pointing at the deleted phase table. That is being fixed inside TASK-157 itself, because it is plan-phase's own artefact and the row's title is that plan-phase stops authoring the block by hand.

+### TASK-243 — a count-preserving substitution destroys canonical records silently, and the drift report goes DOWN as it happens
+
+- **Owner**: Coding Agent
+- **Priority**: P1
+- **Track / mode**: main / project
+- **Deliverable**: A hand-substituted board cannot silently replace canonical records. What the answer is NOT: a fifth predicate bolted onto refuse_to_shrink — that is the shape USER-906 rejected and the reason TASK-203 took four rounds. The question this row settles is where identity belongs: whether a register record carries an identity the board row can be matched against, whether the drift report should be per-record rather than per-count, or whether a substitution is a legitimate hand edit that Perry should REPORT loudly rather than refuse. All three are defensible; the current behaviour is none of them, because the drift number goes DOWN while records are destroyed.
+- **Verification**: Reproduce the measurement first: N rows swapped by hand, records lost and gained, rc 0, drift count falling. Then show the chosen answer changes it, with the same reproduction. The drift report must not decrease while canonical records are being destroyed — that is the property, and it is falsifiable on its own. Mutation: revert whichever mechanism ships and show a NAMED test goes red on a board where a substitution is possible, not on a clean one — TASK-203 round 4 shipped a test on a clean board that could not tell, and that is the defect its round 5 exists to answer. Test all three registers and the zh fixture; the reviewer reproduced it on asks.jsonl there. Baselines name the runner AND the tree.
+- **Dependencies**: TASK-203
+- **Out of scope**: Adding a predicate to refuse_to_shrink. The bound is a count rule by decision (USER-906 option B) and it is correct as a count rule; this row is about identity, which is a different question and must not be smuggled into the same function.

+### TASK-244 — the suite's floor is one module: test_task_writer.py runs alone for 105-149s and no worker count moves it
+
+- **Owner**: Coding Agent
+- **Priority**: P2
+- **Track / mode**: main / project
+- **Deliverable**: The suite's wall-clock is not held hostage by its single largest module. Whatever the mechanism — sharding a module across workers, splitting the module itself, or making its 105-149s cheaper — the floor moves, and the row states which of those it chose and why. If the honest answer turns out to be that the floor is real and the spec's two minutes was wrong, that is an acceptable deliverable: say so with the measurement and correct the spec, rather than reaching the number by running fewer tests.
+- **Verification**: The same id-set equality TASK-230 established must still hold: serial and parallel produce the SAME set of test ids, with zero on either side, across at least five full runs. That is the property that makes a speedup a speedup rather than a loss, and it is not optional here — sharding a module is exactly the change most likely to drop tests silently. Wall-clock before and after with the conditions each was measured under, several runs not one. Mutation: revert the sharding and show a NAMED test goes red. Report the effect on flakiness or decline to claim one, as TASK-230 did — test_host_support's known race fired 1 of 12 there and that was correctly called not a difference.
+- **Dependencies**: TASK-230
+- **Out of scope**: Deleting or skipping tests to move the number. TASK-230's brief led with the rule and it stands here: a faster suite that is quietly less thorough is a worse outcome than a slow one.

+### TASK-245 — tests/parallel main() has never had test coverage, and the guard TASK-230 added there survives its own deletion
+
+- **Owner**: Coding Agent
+- **Priority**: P2
+- **Track / mode**: main / project
+- **Deliverable**: tests/parallel's main() is covered where it makes decisions. At minimum the --ids count refusal and the pre-existing zero-test guard each fail when deleted. Whether that is a run_module monkeypatch, a subprocess invocation, or a refactor that moves the decisions out of main() into something already testable is this row's call — but the answer must not be a unit test on the predicate alone, because that is what exists today and it is what let a live guard rot untested.
+- **Verification**: Delete each guard in main() in turn and show a NAMED test goes red for each — one test per guard, not one covering both. Then show the tests still pass with the guards restored, on a tree where the refusal can actually fire. Baselines name the runner AND the tree.
+- **Dependencies**: TASK-230
+- **Out of scope**: Changing what the guards DO. TASK-230's refusal is correct and was measured firing end-to-end; this row is about whether anything would notice if it stopped.

+### TASK-246 — an unreadable row in .perry/conformance.md is now DELETED by the next declare, not laundered
+
+- **Owner**: Coding Agent
+- **Priority**: P2
+- **Track / mode**: main / project
+- **Deliverable**: A row the reader cannot parse is not silently dropped by the next write. What the answer is depends on what an unreadable row MEANS, and this row settles that: it is either a hand edit Perry should preserve verbatim and keep reporting, or a corruption Perry should refuse to write over until a human resolves it, or a line that may be dropped once the user has been told at the moment it happens. All three are defensible. Silently is none of them.
+- **Verification**: Plant an unreadable row, run a legitimate declare of a DIFFERENT file, and show the chosen behaviour — preserved, refused, or dropped with the user told. The perry-conform status output and the enforce-gate refusal message already print the unreadable count; whatever ships must make the count survive the write that would have removed the row. Mutation: revert the mechanism and show a NAMED test goes red. Cover the pre-existing version-cell case as well as the decoration cases TASK-241 introduces, since the author reports it was already true there. Baselines name the runner AND the tree.
+- **Dependencies**: TASK-241
+- **Out of scope**: Re-opening TASK-241's mechanism. The round trip plus fence tracking is reviewed separately and this row assumes it; the question here is only what happens to a row it declares unreadable.

+### TASK-247 — bin/perry-diagnose still asks 'is there a .perry/config.md' as its test for 'is this configured', at two sites, because that file does not import parsers
+
+- **Owner**: Coding Agent
+- **Priority**: P2
+- **Track / mode**: main / project
+- **Deliverable**: bin/perry-diagnose asks the same question the rest of the toolchain now asks. Both sites go through the one predicate, whatever import that costs, and the cost is stated. If importing parsers into perry-diagnose turns out to drag something unacceptable in — the reason perry-conform's conversion went into viewer/parsers.py rather than bin/perry-state was exactly this kind of coupling — then say what it drags and propose the alternative rather than leaving two narrow checks in place.
+- **Verification**: On a project configured by the STORE alone, with no .perry/config.md, both perry-diagnose sites report it as configured — by command and by output, not by reading the predicate. Each site gets its OWN named test: TASK-233 round 2 showed by cross-check that its two sites fail under different conditions and that one test covering both would have been a false guard, so assume the same here until measured otherwise. Mutation: revert each site separately and show a NAMED test goes red for that site alone. Baselines name the runner, the tree AND the hour — two of this project's failures are data-dependent on live board state and one on whether a row's Next action prose contains an enum word.
+- **Dependencies**: TASK-233
+- **Out of scope**: The value-reading sweep. This row is the existence-check class only — 'is there a config.md' standing in for 'is this configured'. Whether perry-diagnose reads any SETTING from the markdown is a different question and belongs with whatever row closes that class.

+### TASK-248 — a canonical row inside <pre> or an HTML comment still declares a file conformant, and is still laundered
+
+- **Owner**: Coding Agent
+- **Priority**: P2
+- **Track / mode**: main / project
+- **Deliverable**: A canonical row that a human reading the rendered markdown would NOT see as a declaration does not become one. Whether that means modelling HTML blocks the way fences are now modelled, or a narrower rule aimed at the two constructs measured, or a decision that the record is not markdown enough for this to matter, is this row's call — and the third is defensible, because TASK-234 removes the question by removing the markdown. What is not acceptable is the current state, where section 9 reads as though the construct is handled.
+- **Verification**: Plant a canonical row inside <pre> and inside an HTML comment on a copy, and show each is refused or reported rather than parsed as a declaration — each with its OWN named test, since TASK-241 measured that its three decoration shapes fail under different conditions and one test covering several would have been a false guard. Then plant one and run a legitimate declare of a DIFFERENT file, and show it is not laundered into a canonical row. Confirm the seven 'must still declare after a properly closed fence' shapes the reviewer added do not regress. Mutation: revert the mechanism and show a NAMED test goes red for each construct. Baselines name the runner, the tree AND the hour.
+- **Dependencies**: TASK-241
+- **Out of scope**: Reopening TASK-241's fence rule. It is reviewed and passed, and its opening-liberal / closing-strict asymmetry was measured fail-closed in both directions. Also out: waiting for TASK-234.

+### TASK-249 — bash tests/run WRITES PERRY STATE INTO THE REPOSITORY IT RUNS IN — four files, via an intake-sweep discharging a real board row
+
+- **Owner**: Coding Agent
+- **Priority**: P1
+- **Track / mode**: main / project
+- **Deliverable**: The suite does not write to the repository it runs in. Every test that invokes a write-side Perry tool does so against a temp root, and something makes that structural rather than a convention — a fixture that refuses a root inside the repo, or a guard that fails the suite when the tree it started in is not byte-identical when it ends. The second is worth considering on its own merits: it would have caught this the first time it happened, and it is the same shape as the md5-verified restore this project already requires of every mutation.
+- **Verification**: Record the four files' md5s before and after a full run and show they are unchanged. Then plant a test that writes to the live root and show the guard fails the suite — a check that cannot fail on the thing it names is the defect this project catches most often, and a tree-unchanged guard is exactly the kind that can rot. Find the call site: the sweep discharges a real board row, so something reaches perry-task without a --root pointing at a temp dir. Baselines name the runner, the tree AND the hour — and note that this row's fix should make the last of those unnecessary.
+- **Dependencies**: —

+- **2026-08-29** · perry-config render exits 0 while writing nothing when .perry/config.md is absent — it prints 'no .perry/config.md' and returns success, so the store-to-file recovery path its own help text names ('render --write is the store-to-file recovery') cannot recover a deleted file, and a caller checking the exit code is told it worked → dropped 2026-08-30 — WRONG, and the error was mine: perry-config render on a project with .perry/config.md absent exits 2, not 0. Re-measured 2026-08-30 on a copy — 'render --root . >/dev/null 2>&1; echo $?' gives 2. The original reading came from piping the command into head and then reading $?, which is HEAD's exit code and is always 0. Found by the TASK-233 agent, which measured 2 at 658e8c9 and said the spec's sentence was wrong rather than working around it. The refusal is correct and always was; the tool does the right thing and says so. Third measurement error of mine tonight and the second to reach a filed record — the other two were a merge commit claiming two files existed when lint said otherwise, and a live-board failure count handed to three review briefs after it had moved.

+### TASK-250 — ADR-004's 'every writer gates on it' is false of at least three writers, and nothing sweeps for the rest
+
+- **Owner**: Coding Agent
+- **Priority**: P1
+- **Track / mode**: main / project
+- **Deliverable**: Every writer that touches a files[]-shaped path either gates, or is listed as exempt with a reason. The list is produced by a check rather than by hand, so it cannot fall behind a new writer — the same reason TASK-050's WATCHED is pinned by set equality against the enumerated sites rather than maintained. Whether the answer is that ADR-004's sentence gets narrowed to what it actually covers, or that the ungated writers get gated, is what this row settles; both are defensible and the current state is neither.
+- **Verification**: Enumerate every writer that writes a files[]-shaped path, mechanically. For each, show by command and exit code what it does on an undeclared project under PERRY_CONFORMANCE=enforce — gates, or is on the exempt list. Reproduce the two measured today: perry-knowledge promote, and perry-tasks render --write rewriting BOARD.md at rc=0 with md5 before and after. Mutation: add a new ungated writer and show a NAMED test goes red — a hand-maintained list that does not fail when it falls behind is the defect this project has failed four rows for. Baselines name the runner, the tree AND the hour; three of this suite's failures are data-dependent and the count is not a property of the commit.
+- **Dependencies**: TASK-239
+- **Out of scope**: Reopening the decide lane's exemption. TASK-239 settled it and its reviewer ruled the reasoning sound and better founded than the row claimed — ADR-004's own scope word is 'state files', and DESIGN-013 puts decisions/ outside that set. This row is about the writers nobody decided anything about.

+### TASK-251 — tests/run's output offers THREE numbers that all look like a failure count, and two of the three are wrong
+
+- **Owner**: Coding Agent
+- **Priority**: P1
+- **Track / mode**: main / project
+- **Deliverable**: A run of the suite reports its failure count once, unambiguously, in a form that cannot be confused with a module count. Whatever else the output carries, there is exactly one number a reader or a grep can take as THE answer, and every failure appears in the same shape as every other — the bare traceback with no prefix is the defect, not the reader who missed it.
+- **Verification**: Run the suite on a tree with a known failure set and show the three current readings collapse to one. Plant a failure that currently prints as a bare traceback — the test_diagnose reconcile test is the live instance — and show it now carries the same prefix as the rest. Mutation: revert the change and show a NAMED test goes red on the COUNT, not on the formatting; a test that asserts a string appears is not the same as one that asserts two independent numbers agree. Baselines name the runner, the tree AND the hour, and this row should make the last of those matter less.
+- **Dependencies**: —

+### TASK-252 — a register write honours board rows it was never asked about, and the durable 'somebody has seen this' surface does not exist
+
+- **Owner**: Coding Agent
+- **Priority**: P2
+- **Track / mode**: main / project
+- **Deliverable**: Two questions answered, and they may want one answer. Whether a register write may carry forward rows the command did not address — and if not, what an ordinary write does instead on a board it was not asked to reconcile. And whether a destruction that was announced once is durable anywhere afterwards, with a stated clearing condition, so that 'the drift report goes back to zero' stops being the last word on a loss. Either question may be answered 'the current behaviour is correct and here is why' — that is a real answer and it is what neither has today.
+- **Verification**: For the first: construct a board with rows the command did not address and show, by command and exit code, what the chosen answer does. For the second: destroy records, let the announcing write scroll away, and show where the loss is still findable — and show the clearing condition working, because a surface that never clears becomes noise and then becomes ignored. Mutation: revert whichever mechanism ships and show a NAMED BEHAVIOURAL test goes red on a board where the loss is possible; TASK-203 round 4 and TASK-243 both shipped tests on states where their subject could not occur, and both were caught for it. Baselines name the runner, the tree AND the hour — and note tests/run reports three numbers that look like a failure count, only the per-module sum being right.
+- **Dependencies**: TASK-243
+- **Out of scope**: Reopening TASK-243's ending. Report-loudly was ruled forced rather than conventional, by construction: on the intake register a record's identity IS its text, so a typo fix and a row swap are the same edit at the set level, and a refusal would hard-block the typo fix. This row is what comes after the announcement, not whether to announce.

+### TASK-253 — bin/perry-tasks accepts --dry-run and writes anyway
+
+- **Owner**: Coding Agent
+- **Priority**: P1
+- **Track / mode**: main / project
+- **Deliverable**: Either --dry-run writes nothing, or the flag stops existing. If it stays, a test asserts the md5 of every file the write path touches is unchanged across a --dry-run invocation — not that the command printed something that looks like a preview.
+- **Verification**: V4. Two agents reproduced this independently while working other rows: 'perry-tasks render --write' rewrites perry/BOARD.md rc=0 in the same minute 'perry-task add' refuses on that same file for want of a declaration, and --dry-run produces a THIRD distinct md5 of BOARD.md — so it neither leaves the file alone nor reproduces the real write. A flag named --dry-run that writes is a false statement made to every caller, and the callers include agents that were told the flag is how you look without touching. The reviewer must construct the md5 triple itself rather than reading it here, and must check whether any test currently passes BECAUSE --dry-run writes.

+### TASK-254 — bin/perry-lint hands back 22 commands and every one of them drops the root
+
+- **Owner**: Coding Agent
+- **Priority**: P1
+- **Track / mode**: main / project
+- **Deliverable**: The same treatment TASK-234 gave bin/perry-conform: every message that hands the reader a command names it with the root the caller used, and the sweep tool reports perry-lint at zero. If any of the 22 legitimately cannot carry a root, that is a finding about the message, not an exemption.
+- **Verification**: V4. Measured by tests/sweep_handed_back_commands.py, shipped on coding/task-234-conformance-store, under its deliberately crude rule (any backticked command in a message): 22 handed back, 22 missing the root. It is pre-existing and in a different tool, which is why TASK-234 recorded it rather than widening its own scope. The reviewer must re-run the sweep to get its own number rather than taking 22 from here, and must check the crude rule's false-positive rate before treating all 22 as real — the tool states its own blind spot. The consequence to demonstrate is the one TASK-234 demonstrated for perry-conform: a reader routed there by --root PROJ who copies the command back acts on a different project, and the command SUCCEEDS, so nothing tells them.

+### TASK-255 — Perry never shell-quotes a path into a command it hands a reader — shlex appears nowhere in bin/ or viewer/
+
+- **Owner**: Coding Agent
+- **Priority**: P1
+- **Track / mode**: main / project
+- **Deliverable**: A single choke point through which every filesystem path reaching a handed-back command must pass, shell-safe by construction, plus a check that fails if any other site interpolates a path into such a command without it. If a choke point is not the right shape, the alternative must be one that cannot be routed around — the reason this row exists is that the previous fix added the root and the command still did not run.
+- **Verification**: V4. Measured by the PMO on main at 2026-08-30: 'grep -rn shlex bin/ viewer/ tests/' returns NOTHING on main; the project's only use of shlex is two lines in tests/test_conformance.py on coding/task-234-conformance-store, added by that row's own end-to-end proof — which the round-4 reviewer noted would go red today if a single fixture root contained a space. A crude upper bound of 51 sites in bin/ interpolate a root/path-shaped name into a string; the reviewer confirmed the harm on 14 handed-back commands in perry-conform and 4 in perry-migrate. The reviewer must establish the real member count with its own instrument and report the recall of that instrument — the TASK-234 sweep measured 10/15 on planted spellings, so a census from a regex is a lower bound, not a census. The consequence to demonstrate is the reviewer's: on a project at '.../My Project', 'perry-conform migrate --root /.../My Project' copied verbatim exits rc=1 with 'usage: perry-conform migrate — it takes no file' and the record stays unconverted.

+### TASK-256 — The mutation harness's md5 restore-check is circular: it compares the file to bytes it just wrote
+
+- **Owner**: Coding Agent
+- **Priority**: P1
+- **Track / mode**: main / project
+- **Deliverable**: The restore check compares against a digest taken BEFORE the first mutation, or against the git object, and a harness whose restore is incomplete must fail loudly rather than pass. Every brief this project sends prescribes 'restore by md5' — the prescription itself needs correcting, in work/reference and anywhere else it is written down.
+- **Verification**: V4. Found by the TASK-249 round-4 agent against its own harness: its restore kept the first of two edits to one file, and the md5 checks did not notice because they were comparing the file to bytes the harness had just written. It was caught only by a 'diff -rq' against the tip. So a harness can report every mutation restored and leave the tree changed. The reviewer must reproduce the circularity directly — build a harness that makes two edits to one file, restore only the second, and show the md5 check passes while 'diff -rq' fails — and must then check the other harnesses in this repo for the same shape, reporting how many were checked with the command. The consequence to weigh: this is the discipline every agent on this project is instructed to follow, so a silent incomplete restore contaminates the tree that the NEXT measurement is taken on.

+### TASK-257 — The ignored-name bullet pin asserts a substring, not a bullet, and one satisfying string blinds the guard to BOARD.md
+
+- **Owner**: Coding Agent
+- **Priority**: P1
+- **Track / mode**: main / project
+- **Deliverable**: The assertion reads a bullet, not a substring of the section. Plus the two smaller items the round-4 confirmation found: test_a_foreign_perry_project_refuses_the_run should assert its own banner rather than the generic 'refusing to run', and the widened export regex should stop firing on a help line inside the refusal's own message.
+- **Verification**: V4. Found by the round-4 confirmation reviewer, which reproduced three ways to satisfy the pin without a truthful bullet, none of them named by the row: a bullet that names the directory and describes it BACKWARDS; '.claudex' with NO BULLET AT ALL, because that string already appears in the section's control sentence; and '.md' as a suffix, which BLINDS THE GUARD TO perry/BOARD.md and is caught only by the four-files and planted-write tests. The assertion is assertIn(name, section) and the test's name claims it checks a bullet. Two more: test_a_foreign_perry_project_refuses_the_run stays GREEN when the case arms are inverted, because it asserts the generic string rather than its banner — the same shape as the three fixes the row already tightened, one instance further out; and the widened regex has a new false positive, where a help line saying 'export PERRY_PROJECT' inside the refusal's own message turns both pin tests red with a false claim. The reviewer must reproduce all five before fixing, and must check whether asserting a bullet is even well-defined here or whether the section's format needs pinning first.

+
+- **Owner**: Coding Agent
+- **Priority**: P1
+- **Track / mode**: main / project
+- **Deliverable**: copy_repo builds its copy from a source that cannot change underneath it — a git export, or a copytree that tolerates a vanishing file — so the test's verdict is about the code under test rather than about who else was typing.
+- **Verification**: V4. Reproduced by the PMO on the merged tree at 2026-08-30, unintentionally: test_a_module_that_stays_in_a_temp_root_is_green ERRORed with shutil.Error naming three perry/tmp*.tmp paths as 'No such file or directory' — perry-task's atomic-write temporaries, created and renamed away by a PMO write that happened to overlap the copytree. The module reports FAILED (errors=1), and note that errors and failures are different words: a run that sums only 'failures=N' will not see it at all. The reviewer must reproduce the race deliberately (run the module while writing to perry/ in a loop) rather than wait for it, and must check every other test in the repo that copies PERRY_HOME for the same exposure, reporting how many were checked with the command.

+
+- **Owner**: Coding Agent
+- **Priority**: P1
+- **Track / mode**: main / project
+- **Deliverable**: Three things: an assertion that the fixture root actually carries hostile characters, so the 19-tests-red property cannot be silently undone; a positive control for the sweep's phrase boundary; and either coverage or a recorded decision for the two bypass shapes below.
+- **Verification**: V4. From the TASK-234 round-5 review, which merged the row — these are its non-blocking remainder. (a) R5-14: replacing the fixture root with 'proj' leaves BOTH modules green. The hostility is the thing 19 tests depend on and nothing pins it; it is section 11's own table one row further on. (b) 8 of 19 fresh bypass spellings get past the source rule, in two shapes the fixture does not plant: assembling the flag value BEFORE the template (+, %, join, Template — render() returns None for a BinOp over a Name), and a LITERAL QUOTE IN THE TEMPLATE, which truncates TAIL so the interpolation is never examined and the sweep prints 'ok'. Neither is reachable in the shipped tree today, verified by AST — so this is a guard-strength row, not a live defect. (c) R5-11 is the round's one surviving mutation: the sweep's phrase boundary, TAIL excluding the backtick, has no positive control. The reviewer must re-derive the 8-of-19 with its own planted set rather than take the number.

THE RULING: a measured, listed remainder of 8 of 76 DISCHARGES the amendment — round 10's rule was 'measure the reach and state the remainder', not 'make it zero'. The reviewer did not trust the author's instrument: its own sys.settrace returns 8 by function entry AND by line execution with the same eight members; it validated the census's static verdict EXHAUSTIVELY by planting at all 76 sites one at a time, with offenders_by_symbol agreeing with the static flag 76 OF 76; round 10's 20 reproduces exactly; and the previous reviewer's twelve reconciles precisely as 13 carried sites in 12 names. It also confirmed the framing this row was failed twice for getting wrong — 'provenance, not a key-name list' survives adversarial testing, with key zulu CAUGHT, key header holding non-row values silent, and CARRIED_KEYS never read by offenders_by_symbol. THREE CORRECTIONS SENT BACK. (1) The round gets WHY three of its eight are open wrong: section 2.3 says all eight are rooted in a call into ANOTHER MODULE, and the three bin/perry-lint sites are not — tables() and tables_with_lines() are both defined in bin/perry-lint at :194 and :209. The escape is that _paths has no comprehension branch, proven with a synthetic file containing no cross-module call anywhere: the shape ESCAPED, and the identical file minus the comprehension link was CAUGHT. Same species as round 10's error one rung smaller — which and how many right, why wrong for three — and it changes the next target from 0 to 5, because three of the eight are closable by the file-local machinery already built. (2) 'Nine single-entry mutations' is EIGHT: the table omits D42 from five rows, so R11-5 reddens D38 and D42. Second time a mutation table has predated its own corpus additions on this row. (3) TWO BRANCHES OF THE NEW MACHINERY STILL SURVIVE THEIR OWN DELETION — the YieldFrom step and ast.Set in the literal branch — which the eighteen-probe sweep did not reach; either test them or delete them, but do not leave the sweep's clean bill of health standing over them. ALSO: the write hazard reproduced independently in the reviewer's own export, a third confirmation of TASK-249; and the reviewer could not verify 9 of the 23 mutations by the author's anchors, substituting an exhaustive plant sweep and a twelve-branch hunt.
+- [TASK-050] next action · V4 ROUND 11 PASS 2026-08-30; corrections at 642091f now in DELTA CONFIRMATION with the same reviewer, because they went beyond what was charged and the PASS predates them. WHAT THE CORRECTIONS DID. Correction 3 was charged as two branches surviving their own deletion; the author fixed both — ast.Set DELETED as unreachable, since a row is a list and a list is not hashable so a row cannot be an element of a set literal, and yield from TESTED by D43 with R11-24 reddening D43 alone — and then decided the real gap was its own CANDIDATE LIST. It rebuilt the sweep to take candidates from git diff rather than from itself: 128 candidates over the 337 new or changed lines, each mutated on the AST and re-emitted with ast.unparse so a multi-line condition cannot break syntax, with a control run that unparses without mutating and stays green, and every corpus-clean candidate re-probed against the runtime half so that green means the corpus is caught AND the remainder test is unmoved. Result: 60 red in the corpus, 26 red in the watch, 22 unneutralisable, 20 green. IT FOUND FOUR MORE UNPINNED DETECTION BRANCHES beyond the review's two — D44 _rpaths_of by attribute name, D45 _bind_element on a comprehension generator, D46 the cell() half of the tuple unpack, D47 the subscript half of the carried write — each now single-entry. The twenty remaining greens are claimed to contain NO detection branch and all twenty are named in section 1.5 with why a planting corpus cannot pin each, because that is a claim; two were re-verified by hand on the reasoning that a sweep disagreeing with a hand check is a broken sweep, and both agreed. The sweep's own bounds are stated: whole if tests rather than conjuncts, no constants or operators, tests/header_rule.py only. DRIFT 42 to 47 all caught, CLEAN 14 none flagged, 27 mutations all red, eight single-entry. Correction 1: reproduced the synthetic-file proof itself before changing anything, then fixed the why in three places including UNCOVERED's own comment, where the next round will actually read it — five of eight cross-module, three _paths lacking a comprehension branch, next target 5 not 0. Correction 2: the table re-measured in one run, R11-5 reddening D38 D42 D43 D44 D45, and EVERY ROW NOW CARRIES ITS ANCHOR, which is the fix for the reviewer being unable to verify 9 of 23 from a table that named mutations and not lines. The author records that this is the SECOND time on this row a mutation table was published against a corpus older than itself, and that both times someone else found it. Baselines unchanged: 102 modules / 3036 tests / the same 3; offenders_by_symbol empty; 76 sites / 27 static-blind / remainder 8.

THE SECTION 7 CAVEAT: a new 7.0 placed AHEAD of the literal-property gap, because it is the cost of the ending rather than a limitation of it — under REPORT, fixing lgoin to login in a Request cell prints a data-loss warning, and the section says plainly that this is correct, why Perry cannot know better (on ## Intake the identity IS the text), that the alternative is the refusal that hard-blocks the typo fix, and that the noise is BOUNDED TO intake because editing a USER- or RX- row's text leaves its identity alone. It names narrowing it via a minted intake key as a follow-up row, not a patch. Section 7.1 now carries the reviewer's reasoning verbatim.
+- [TASK-251] summary · Measured on this repository 2026-08-30, and it has already misled two agents. Grepping '^FAIL:' gives 3; summing the per-module 'FAILED (failures=N)' gives 4; and the summary line reads 'N module(s) red', which is 3. Only the sum is the failure count. The cause: tests/run prints test_diagnose's test_the_queue_register_reconciles_with_the_queue_on_this_repository as a BARE TRACEBACK with no FAIL: prefix, while the other three carry it. THE IRONY IS THE FINDING: TASK-239's author disclosed this exact trap about its OWN harness in its result — 'named_failures collects lines prefixed FAIL: / ERROR:, and tests/run prints one of the pre-existing failures as a bare traceback with no such prefix' — found it, said it out loud, and corrected for it by reporting deltas rather than absolute counts. It is the same trap that then produced the number that author was second-guessed on. Its reviewer walked into it too, on the first grep of its own log, and only caught it because it went looking for why another agent's number differed. The whole baseline dispute of 2026-08-30 — 4 versus 3 at the same commit — was this, not board state and not uncommitted edits. → MECHANISM FOUND 2026-08-30 by the TASK-249 agent while retracting a number this trap had produced: tests/parallel:283 prints a red module's stderr TRUNCATED TO ITS LAST 25 LINES, and nothing is visibly elided. test_diagnose fails twice; the second failure's FAIL: header survives that window and the FIRST ONE'S DOES NOT, so the first arrives as a bare traceback with no prefix. That is why the output offers three numbers that all look like a failure count — grepping ^FAIL: gives 3, summing the per-module FAILED (failures=N) gives 4, and the summary line 'N module(s) red' gives 3 — and only the sum is right. It has now caught three agents in twelve hours, one of whom had DOCUMENTED the trap in its own result before walking into it, and one of whom used it to accuse a correct measurement of being wrong. The truncation is the root cause: the missing prefix is not a formatting choice, it is a line that fell off the top of a 25-line window.

The gate refused the WHOLE command on main, bodies included, and there is no reachable main state where it did not. Removing it was correct — after TASK-235 nothing in the lane has a files[] shape, so a gate on it could not fire — but the effect is that the decide lane went from fully gated to fully ungated, and perry-decide's own justifying comment closes with 'only the index write was ever gated', which is false.

Not an error: a success-shaped silence. That sentence was rewritten in this very round under the wall-standard banner and the omission was left in. All 16 helper invocations assert this message while themselves running with --root, which is why no test saw it. TWO NUMBERS CORRECTED: the helper is routed through by 14 distinct test methods / 16 invocations, not 17 — the reviewer measured it at runtime by wrapping the helper; 17 was section 4.3's count of MOVED tests, carried into a sentence about ROUTING. And only 4 of those 16 reach the fixed-point branch the FAIL was about; the other 12 satisfy 'locates' via the pre-existing 'line N:'.

Running the suite modifies .perry/events.jsonl, perry/BOARD.md, perry/intake.jsonl and perry/journal/<today>.md in whatever repository it executes in, by running an intake-sweep that discharges one board row. The experiment: restore the four files, run the suite, and the same four move again. THE SWEEP IS IDEMPOTENT, WHICH IS WHY A SECOND RUN LOOKS CLEAN — that is why nobody noticed. It matters beyond tidiness: two of the suite's three standing failures are data-dependent on board state, so the suite perturbs the very state its own results depend on. It is also how a stray intake-sweep event with actor 'agent' ended up committed on a coding branch and was caught only because an append-only file conflicted at merge; a fast-forward would have carried it into main silently. → V4 ROUND 2: PASS with three defects, one blocking merge.

+- [intake] arrived 2026-08-30 · Two V4 reviewers measured the SAME commit within an hour and got different failure counts (4/3 and 5/4 at main@5367c06); the difference is the recorded test_host_support flake, but nothing in the suite output says so. A reviewer who measures 5 has no way to tell a flake from a regression except by asking another reviewer, and the second measurement is exactly what a review is supposed to make unnecessary. Either the flake is quarantined and named in the output, or the suite prints its own known-flaky set so a count that includes one is legible as such. Related: TASK-251 (three numbers that all look like a failure count).

This is the same defect the project just wrote a knowledge card about (verification/numbers-migrate-between-sentences) committed by the person who wrote the card, in a brief sent an hour later.

The fix is structural rather than a patch: root_arg is now KEYWORD-ONLY WITH NO DEFAULT on both migrate_record and declare, so a caller that has a root must pass it; bin/perry-migrate apply_plan passes its own because declare converts the record first and that step can refuse. The unreadable-rows branch also stopped saying 'run ... AGAIN', which is wrong when reached from declare. THE SWEEP SHIPPED AS A TOOL: tests/sweep_handed_back_commands.py, read off the AST so a docstring ABOUT the defect is not counted as one. The class has 7 members: bin/perry-conform 2 -> 0 (exit 0, EMPTY SET), the rest of the runtime import closure 0 of 36 mentions, bin/perry-migrate 5 -> 3. The 3 left all name a DIFFERENT tool from functions with no root in scope — recorded, not fixed. Under a deliberately cruder rule bin/perry-lint has 22, all 22 missing: pre-existing, a different tool, recorded with the command. The tool states its own blind spot instead of claiming completeness. END-TO-END PROOF: the test plants two real projects, MEASURES THE HARM FIRST (bare command -> rc 0, 'nothing to convert', reader's record untouched), then extracts the command from the refusal text and runs it unedited from the other project's directory. Three layers each demonstrated by the mutation the other two miss — M34 (a correctly-spelled WRONG root) reddens only the end-to-end test, M32 (wrong runtime value) only the 16 helper invocations, M40 (template) only the source guard. TWO GREEN MUTATIONS FOUND AND CLOSED: M35, apply_plan dropping its root into C.declare, was green across all of test_migrate AND test_conformance — that route was the one member of the class no test held; M36, rollback_message, was green because 'perry-migrate restore <id>' is named on TWO code paths and the test read the other one, re-pointed and now red. Numbers corrected: 14 methods / 16 invocations not 17; only 4 of 16 reach the fixed-point branch, said where the coverage is claimed; '29/29' restated and then RE-EARNED at 40/40 by re-running the whole harness plus 11 new. CRLF guard widened to a regex over bin/perry-conform AND bin/README.md with positive pins on the correcting sentence in each — not a ban on the phrase, since both files use it correctly elsewhere. Suite 103 modules / 3141 tests / 4 failures across 3 red modules, against a baseline it measured itself this session (4 across 3, no test_host_support); md5 of all tracked files identical before and after every run, and its baseline digest matches the round-3 reviewer's for the same tip.

BLOCKS MERGE, one bullet: .claude and .gstack are absent from tree_guard.py's 'What it does NOT catch, said plainly' list, while .DS_Store and __pycache__ — STRICTLY NARROWER holes — each have a bullet, and the row's own section 8.4 calls the .claude hole 'the widest of the five'. WHAT HELD: MR-3 re-run confirms the row's claim exactly — only the new test dies, the old root.resolve() test stays green, same under a full revert; run_suite really does invoke bash tests/run; the 24/18 derivation is non-vacuous in BOTH directions (0o777 caught by os.access, 0o644 caught by assertTrue(execs)); the board-dependence gap is CLOSED, measured on three board states at 4/3 each; and the contaminated run STRENGTHENS rather than undermines the numbers. WHAT BROKE: the docstring pin's CLAIM is wider than the pin — it reads which of two STRINGS is in tests/run, not which mechanism shipped, so a live re-aim spelled 'export "PERRY_PROJECT=$ROOT"' or 'PERRY_PROJECT=...; export PERRY_PROJECT' evades the regex, and a refusal left dead under 'if false' still reads as 'refuse' — three green mutations. All are caught by the BEHAVIOUR tests, so there is no hole in protection, only in what the test says about itself; but the admitted accuracy gap is TOTAL, since a bullet asserting the exact opposite behaviour, or cut to four words, leaves all 21 tests green. TWO NEW FINDINGS on the resolution fix: case-differing spellings are STILL falsely refused, and the fix NEWLY ACCEPTS relative paths whose meaning is cwd-dependent — a regression the fix introduced. One correction to the PMO's brief: 24 and 18 DO still appear, in a tests/test_tree_guard.py:516 docstring, though in no assertion. Reviewer's own mutations 9/9 red.
+- [intake] arrived 2026-08-30 · The tree guard's ignore list matches a directory name AT ANY DEPTH, and a file written inside an already-existing ignored directory is invisible — both reproduced by the TASK-249 round-3 reviewer, and both wider than the row had recorded.

Supersedes the narrower row filed earlier today.
+- [TASK-234] summary · ROUND 3 CORRECTIONS IN at f783dd5, five commits, worktree clean. The fix is structural rather than a patch: root_arg is now KEYWORD-ONLY WITH NO DEFAULT on both migrate_record and declare, so a caller that has a root must pass it; bin/perry-migrate apply_plan passes its own because declare converts the record first and that step can refuse. The unreadable-rows branch also stopped saying 'run ... AGAIN', which is wrong when reached from declare. THE SWEEP SHIPPED AS A TOOL: tests/sweep_handed_back_commands.py, read off the AST so a docstring ABOUT the defect is not counted as one. The class has 7 members: bin/perry-conform 2 -> 0 (exit 0, EMPTY SET), the rest of the runtime import closure 0 of 36 mentions, bin/perry-migrate 5 -> 3. The 3 left all name a DIFFERENT tool from functions with no root in scope — recorded, not fixed. Under a deliberately cruder rule bin/perry-lint has 22, all 22 missing: pre-existing, a different tool, recorded with the command. The tool states its own blind spot instead of claiming completeness. END-TO-END PROOF: the test plants two real projects, MEASURES THE HARM FIRST (bare command -> rc 0, 'nothing to convert', reader's record untouched), then extracts the command from the refusal text and runs it unedited from the other project's directory. Three layers each demonstrated by the mutation the other two miss — M34 (a correctly-spelled WRONG root) reddens only the end-to-end test, M32 (wrong runtime value) only the 16 helper invocations, M40 (template) only the source guard. TWO GREEN MUTATIONS FOUND AND CLOSED: M35, apply_plan dropping its root into C.declare, was green across all of test_migrate AND test_conformance — that route was the one member of the class no test held; M36, rollback_message, was green because 'perry-migrate restore <id>' is named on TWO code paths and the test read the other one, re-pointed and now red. Numbers corrected: 14 methods / 16 invocations not 17; only 4 of 16 reach the fixed-point branch, said where the coverage is claimed; '29/29' restated and then RE-EARNED at 40/40 by re-running the whole harness plus 11 new. CRLF guard widened to a regex over bin/perry-conform AND bin/README.md with positive pins on the correcting sentence in each — not a ban on the phrase, since both files use it correctly elsewhere. Suite 103 modules / 3141 tests / 4 failures across 3 red modules, against a baseline it measured itself this session (4 across 3, no test_host_support); md5 of all tracked files identical before and after every run, and its baseline digest matches the round-3 reviewer's for the same tip. → ROUND 4 REVIEW: FAIL. Review at review/task-234-round4 fa2aa5c, merged. THE FAIL: _root_flag builds ' --root {root_arg}' UNQUOTED, and shlex.quote appears nowhere in bin/ or viewer/. On a planted project at '.../My Project' the refusal THIS ROUND REWROTE hands back 'perry-conform migrate --root /.../My Project'; copied verbatim it exits rc=1 with 'usage: perry-conform migrate — it takes no file', record unconverted. Same standard as the round-3 FAIL, same sentence, found the same way — and the standard is the row's own: 'a named command that errors is worse than none'. It covers all 14 handed-back commands in perry-conform and 4 in perry-migrate, including the message_for branch round 3 signed off. The row's own end-to-end proof runs shlex.split on the message and would go red today if one fixture root had a space. One-line fix. FOUR GREEN MUTATIONS: R-N3 and R-N4, two of rollback_message's three call sites in apply_plan (the write-failed and digest-mismatch paths, TASK-044 guarantee 3) can drop the caller's root with all of test_conformance AND test_migrate green — green because the tests that reach them call apply_plan(plan, SCHEMA) with no root, which is the round-3 defect one file over; controls R-N5 and R-N6 are both RED. R-N8: the SWEEP'S OWN ROOT regex neutered to match everything leaves the suite GREEN, because assertGreaterEqual(len(handed), 12) guards against finding nothing, not against calling everything ok — R-N9 is RED, so only the ok/bad half is unguarded. R-N13: deleting the update_expected_after(point, P.CONFORMANCE_LEGACY_FILE) call this branch added is green across test_migrate, because no test applies a migration to a project holding a legacy record and then restores it. TWO RESULT CLAIMS THAT DO NOT SURVIVE MEASUREMENT: section 6.1's 'M34 is invisible to BOTH' is false — M34 reddens 7 tests / 5 methods including 4 helper invocations, because assert_every_command_carries asserts the EXACT root; and M40 is M30 byte-for-byte, so 'caught only by reading the source' cannot hold for either. Section 10.9's 'functions with no root in scope' is untrue for 2 of the 3 excused members: _plan_task_store(plan) has plan.project_root two lines above, and the command handed back there is 'perry-tasks render --write', which WRITES the cwd project's BOARD.md — worse harm than the rc=0 no-op the FAIL was about, and section 10.9 does not say so. SWEEP RECALL MEASURED AT 10/15 on planted spellings, so '7 members / 3 left' is a LOWER BOUND, not a census. CRLF regex catches 3 of 9 plausible overclaims and evades 5. HOLDING: sweep exit 0 / empty on perry-conform; the 7->3 census reproduces exactly off git show; extraction genuinely programmatic with no constructed expected string; M35 and M36 both RED for the stated reason with M36's original path still covered; TypeError on omission with nothing swallowing it; no weakened call site; keyword-only shape confirmed by inspect.
+- [TASK-253] summary · Filed 2026-08-30 by the PMO after finding the defect lived only inside TASK-239's prose and had no row of its own. A finding buried in another row's narrative is not a tracked finding. Also open, and possibly the same root: the gate is consulted at three sites (perry-task, perry-goals, perry_md_store.py:1157) and perry-tasks/render is not one of them. → SHARPENED 2026-08-30 by the TASK-234 round-4 review: 'perry-tasks render --write' is not merely a writer that ignores the gate, it is a command Perry HANDS BACK TO READERS. bin/perry-migrate section _plan_task_store prints it in a refusal, from a function that has plan.project_root two lines above and does not pass it — so a reader who copies it runs 'render --write' against whatever project their cwd happens to be in, and it rewrites that project's BOARD.md. The review calls this worse harm than the rc=0 no-op that failed TASK-234 round 3, because that one changed nothing and this one changes a file. That makes this row a hazard, not a tidy-up.

+- [TASK-249] summary · ROUND 3 REVIEW: PASS, review at review/task-249-round3 1291335, merged. FIVE full suites measured in-session, 4 failures across 3 red modules on every one (main at two different commits, the tip, and two merge probes), same four by name, no test_host_support; the arithmetic re-derived independently. BLOCKS MERGE, one bullet: .claude and .gstack are absent from tree_guard.py's 'What it does NOT catch, said plainly' list, while .DS_Store and __pycache__ — STRICTLY NARROWER holes — each have a bullet, and the row's own section 8.4 calls the .claude hole 'the widest of the five'. WHAT HELD: MR-3 re-run confirms the row's claim exactly — only the new test dies, the old root.resolve() test stays green, same under a full revert; run_suite really does invoke bash tests/run; the 24/18 derivation is non-vacuous in BOTH directions (0o777 caught by os.access, 0o644 caught by assertTrue(execs)); the board-dependence gap is CLOSED, measured on three board states at 4/3 each; and the contaminated run STRENGTHENS rather than undermines the numbers. WHAT BROKE: the docstring pin's CLAIM is wider than the pin — it reads which of two STRINGS is in tests/run, not which mechanism shipped, so a live re-aim spelled 'export "PERRY_PROJECT=$ROOT"' or 'PERRY_PROJECT=...; export PERRY_PROJECT' evades the regex, and a refusal left dead under 'if false' still reads as 'refuse' — three green mutations. All are caught by the BEHAVIOUR tests, so there is no hole in protection, only in what the test says about itself; but the admitted accuracy gap is TOTAL, since a bullet asserting the exact opposite behaviour, or cut to four words, leaves all 21 tests green. TWO NEW FINDINGS on the resolution fix: case-differing spellings are STILL falsely refused, and the fix NEWLY ACCEPTS relative paths whose meaning is cwd-dependent — a regression the fix introduced. One correction to the PMO's brief: 24 and 18 DO still appear, in a tests/test_tree_guard.py:516 docstring, though in no assertion. Reviewer's own mutations 9/9 red. → ROUND 4 FIXES IN at f8bc100, five commits. BLOCKER CLOSED and pinned: the bullet is in the 'What it does NOT catch' list carrying scope re-derived with controls — a directory appearing mid-run is invisible INCLUDING ITS OWN CREATION; with .claude/ already present at snapshot it is not in the manifest at all, so rewriting a file in it and creating another gives compare() == []; and the match is on the NAME AT ANY DEPTH, so perry/evidence/.claude/ and perry/.gstack/ are invisible while the same writes into .claudex/ are reported. The pin is the good part: test_every_ignored_name_is_a_bullet_in_the_list_of_what_is_missed is red when the bullet is deleted AND red when a fifth ignored directory is added WITH THE EQUALITY PIN MOVED WITH IT — which the equality pin alone would not catch. THE FIVE ITEMS: (1) it reproduced all three green mutations plus both bullet rewrites ON THE UNFIXED TIP FIRST, confirming the pin was green in all five, then took BOTH halves — the claim narrowed (class renamed to say it checks the bullet's VOCABULARY against the token spelled in tests/run, docstring states the measured gap) and the pin widened to catch both export spellings, with the refuse token anchored to a non-comment line. The dead-refusal-under-'if false' case stays uncatchable by string search and is recorded as such rather than papered over. (2) IndexError replaced by two FAILs with sentences, verified with both banners reworded. (3) case-differing spellings now accepted, comparison is 'test -ef' on device+inode. (4) relative paths REFUSED with their own banner and reason — decided, not incidental; the 17-spelling sweep re-run shows four changed, all in the intended direction, nothing became accept-everything. (5) 24 and 18 removed, grep returns nothing. TWENTY mutations, four green, all reported. MC1 is the most useful: reverting -ef to round 2's string comparison kills exactly one test and it is the new one — round 3's blindness finding, one layer out. THREE OF ITS OWN FIXES WERE GREEN UNDER THEIR FIRST MUTATION and were tightened: the relative-refusal assertion matched the word 'relative' in an explanatory paragraph rather than in the banner, setUp's terminator, and the doc pin would have passed on three empty sets. Five suites measured, 4/3 on every one including both board states of a moving main; the final tip differs from the probed merge only by the result document, and re-merging is clean.

Measured end to end on a throwaway project at '.../My Project (v2) & draft', with the refusal's line PASTED INTO A REAL /bin/sh: rc=0, the reader's record converted with its own date, the project they were standing in untouched. WHY THIS SHAPE CANNOT BE ROUTED AROUND LIKE THE LAST ONE, in its own words: _root_flag was ALREADY a choke point, and it failed because a choke point is a CONVENTION. So the shape is the choke point PLUS a source rule — the sweep reports any {...} inside a handed-back command that is not a sanctioned quoting spelling, and FLAG_VALUE reads a long flag's value in ANY template, which is the only rule that can reach _root_flag's own body since it names no tool. The suite guard runs it over both tools, so the bypass spelling is RED, not discouraged. The new rule immediately found a SECOND member: message_for's DRIFTED branch glued the unreadable-lines parenthetical onto the command line, and pasted into a shell that is 'syntax error near unexpected token (', rc=2. FIXTURES: every fixture root in both modules is now nine shell-hostile characters, and NINETEEN TESTS WENT RED ON THAT CHANGE ALONE; the proof also runs the command through /bin/sh -c because shlex.split does not glob or expand; the helper now PARSES rather than substring-matches and moved to tests/handed_back.py because test_migrate held a second hand-written copy — which surfaced that commands_named required 4 spaces of indent while the sweep's CUE required 2, so do_restore's listing was invisible to one of them and A TEST WAS ASSERTING OVER AN EMPTY EXTRACTION. SWEEP RECALL 18/19, and 14/15 on the reviewer's own set, up from 10/15. FOUR GREEN MUTATIONS CLOSED STRUCTURALLY: apply_plan and render no longer take a root at all — Plan carries the one the caller TYPED, plan_project requires it with no default; the digest-mismatch path had no test and has one; the sweep's ok/bad decision has a positive control; the legacy-record restore round trip is a test. On why the keyword-only fix had not reached perry-migrate, its own account: 'round 4 argued for the shape in the RESULT and then gave perry-migrate three parameters with silent defaults'. CORRECTIONS: section 6.1's three-layer argument is rewritten to the measurement — M40 is byte-for-byte M30 and NO mutation of that line is caught by exactly one layer, so the argument is dropped rather than defended; what is measured instead is that M44, M52 and M53 are red on the source guard and nothing else, three real defects in messages no fixture reaches. Section 10.9's three excused members all carry the root now, both tools at zero. The census is restated as a lower bound wherever quoted. The CRLF regex went 3/9 to 9/9, and the LOOSER widening was tried and REJECTED on measurement because it fires on the correcting comment itself. 57/57 mutations red.

+- [TASK-255] summary · Filed 2026-08-30 from the TASK-234 round-4 FAIL. TASK-234 fixes perry-conform and TASK-254 covers perry-lint's 22, but the class is project-wide and neither row owns it: no path is shell-quoted anywhere in Perry. The standard violated is bin/perry-conform:360 — 'a wall — every branch here ends in a command the reader can run' — and this is the second consecutive round to fail it in the SAME SENTENCE, one layer deeper: round 3 failed because the command dropped the root, round 4 because the command with the root does not run. Depends on TASK-234 landing its choke point first so this row generalises a shape rather than inventing one. → SIZED 2026-08-30 by the TASK-234 round-4 agent, which measured the class OUTSIDE the two tools it was fixing: 63 handed-back commands across the other twelve bin/perry-* executables, 25 of them WITHOUT THE ROOT, including six more places that hand back 'perry-tasks render --write' — the command that writes another project's BOARD.md. It also reports that its raw-interpolation rule OVER-REPORTS there (3 genuine, 16 being FLAG_VALUE reading a flag mentioned in prose) and says so rather than quoting 19. So this row's population is 25 confirmed root-droppers plus 3 confirmed raw interpolations, and the instrument's precision on the rest of bin/ is known to be poor. TASK-234 also shipped the shape this row should generalise: a choke point PLUS a source rule, on the argument that a choke point alone is only a convention — _root_flag was already a choke point and that is exactly why it failed.

The reviewer went looking for the THIRD layer — rounds 3 and 4 having failed on the same sentence one register deeper each time — using eight distinct refusal surfaces driven on planted hostile-root projects, every command extracted by the SHIPPED extractor and pasted into a real /bin/sh. It is not there: all parse, all carry the exact typed root, including the full round trip, a state file named 'My Notes & draft.md', a RELATIVE --root, and perry-migrate's actual restore putting two files back. Newline, which the row called unmeasured, is milder than claimed — _q quotes it correctly and the two-line block pastes and runs rc 0. TWO MUTATIONS TURNED THE ROW'S ARGUMENT INTO A MEASUREMENT: R5-16, a friendly fixture root PLUS round 4's defect put back, drops 24 red methods to 2, and both survivors are the source rule and the backtick test — so 'a choke point is a convention' is now an experiment rather than an argument. R5-15, _q double-quoting with escapes, leaves shlex.split reading the right root so all 16 helper invocations and the source guard stay GREEN while /bin/sh expands  and the end-to-end proof goes red — that is exactly the shell-layer-only mutation the RESULT said it could not construct, which makes the /bin/sh paste load-bearing rather than decorative. 57/57 of the row's own harness reproduced independently plus 16 of the reviewer's, restored from git show and never from its own bytes. ONE SURVIVOR: R5-11, the sweep's phrase boundary (TAIL excluding the backtick) has no positive control. Suite main 105/3148/4, tip 103/3150/4, probe 105/3200/4, ZERO errors throughout, test_host_support absent from all three.

Over the other twelve it is 42 handed-back commands / 208 mentions, not 63 / 232 — the difference is exactly perry-conform and perry-migrate's own 21/24, which TASK-234 has now fixed. So THIS ROW'S POPULATION IS A THIRD SMALLER THAN FIRST FILED. The counts that actually matter reproduce exactly: 25 rootless and 19 raw, with both splits confirmed. Two further corrections: of the '3 genuine' raw interpolations outside these tools, TWO INTERPOLATE THE VERB, NOT AN ARGUMENT, so the genuine count is 1; and the backtick residual TASK-234 sized at two is EIGHT, of which only the message_for pair is pinned — two of the unpinned six are 'perry-tasks render --write' and 'write --from-board', the ones that WRITE. Whoever takes this row should re-derive the census a third time rather than inherit any of these numbers: it has now been measured three times and been wrong twice.

+# verification/numbers-migrate-between-sentences — a count measured for one claim gets reused in a sentence about a different claim, and stays plausible
+
+- Kind: knowledge
+- Owner role: —
+- Source: TASK-234 round 3 · evidence/2026-08/TASK-234-round3-v4-review.md; TASK-241; the PMO's own briefs, 2026-08-29
+- Last verified: 2026-08-30
+- Invalidated by: a convention that every number in a record carries the command that produced it, enforced by something that can fail
+
+A number is measured, correctly, for one purpose. Later a sentence needs a
+number of roughly that shape, and the measured one is close enough to reach
+for. It is not re-measured, because it was measured — the memory of having
+counted is doing the work that the counting did.
+
+Three instances in one session, all caught by someone other than the author:
+
+| the number | true of | reused to claim | found by |
+|---|---|---|---|
+| **17** | tests *moved* in § 4.3 | tests *routed through* the helper | the round-3 reviewer, wrapping the helper at runtime: **14 methods, 16 invocations** |
+| **5 failures** | the suite an hour earlier | the suite now | the PMO, after the figure had reached three review briefs |
+| a proof of a *whole-file* check | what the reviewer showed | a proof that a detector was *complete for its class* | a second reviewer, after it had passed through a spec, a RESULT and a commit message |
+
+The shape is constant: **the number survives the move because nothing about it
+looks wrong.** It is the right order of magnitude, it came from a real
+measurement, and the sentence it lands in is about a neighbouring property of
+the same object. Nothing in the text records which question it answered, so
+nothing in the text can contradict it. A reviewer who re-derives the *claim*
+still passes it; only a reviewer who re-derives the *number* catches it.
+
+## What actually catches it
+
+Not care, and not review — all three of these were written carefully and read
+by someone. What caught them was **re-measuring the number against the sentence
+it now sits in**, using an instrument chosen for the new question:
+
+- the 17 fell to wrapping the helper and counting invocations at run time,
+  because that is what "routed through" means, and reading § 4.3 is not.
+- the 5 fell to re-running the suite.
+- the proof fell to reading what the reviewer had actually demonstrated.
+
+So the rule is not "check your numbers". It is: **a number quoted in support of
+a claim must have been produced by an instrument aimed at that claim.** If the
+record cannot say which command produced it, the number is a memory, and a
+memory is not a measurement.
+
+## The cheap defence
+
+Carry the command with the number, in the same sentence, always — the way this
+project already requires for "these were the rest" (which must be a command
+whose output is the empty set, or be written as a count). A number with its
+command attached cannot migrate: moving it to a new claim visibly moves a
+command that does not answer the new question, and that is legible to any
+reader, including the author a day later.

+## Phase Focus
+
+**Phase 002 made the stores exist. Phase 003 makes the code live on them.**
+
+Six projection stores are declared in `schema/state-schema.json § claims[]`.
+Four exist on disk — `tasks.jsonl`, `okr.jsonl`, `risks.jsonl`,
+`.perry/config.jsonl`. Two were built and never imported: `intake.jsonl`
+(TASK-196) and `asks.jsonl` (TASK-197). And `perry-lint`, the one command that
+is supposed to make ADR-007's guarantee checkable, gives a drift verdict for
+**two of the six** — tasks and risks. `okr.jsonl` and `.perry/config.jsonl`
+each have a working `diff` tool that the census does not call.
+
+Meanwhile the read side still treats rendered markdown as truth where a store
+already exists: `parse_tracks` is called at four sites in `bin/` that use
+`.perry/config.md` as the authority on a project's tracks, while
+`.perry/config.jsonl` sits beside it holding the same nine records.
+
+The phase is scored when a store's existence, its drift verdict, and the code
+path that reads it are all one answer instead of three.
+
+This phase does **not** migrate anyone else's project — `TASK-097` carries
+forward untouched — and it does **not** stop Python parsing the document class
+(`design/`, `DECISIONS.md`, `phase/`, `.perry/roles/`). Phase 002's Not Doing
+deferred that to "a later phase"; this is not that phase either, and folding it
+in would put a ten-section prose file in the same migration as a 35-column
+table for the second time.
+
+## Operating Rules
+
+- **Count call sites, never names.** Phase 002's most expensive recurring
+  defect was locating an implementation by grepping its name — it recurred
+  roughly ten times, once over-counting and once missing a whole second
+  reporter. Every KR below names the expression or the call and, where the
+  baseline is small, the file and line.
+- **A gate is not green until it has been shown able to go red.** Reverting the
+  line that implements a check must break its test. A pass that was never
+  falsifiable is not evidence (phase 002, lesson 4).
+- **An absent store reports `unchecked`, never `clean`.** This is the property
+  under test in `P003-O1-KR3`, and it is also a rule for anything written this
+  phase.
+- **Agent autonomy**: agents may delete, fence and re-point code paths inside
+  this repository, and may import Perry's own stores. Agents may **not** touch
+  any project other than Perry's own.
+- **User authorization required for**: anything in `.perry/hook.md §
+  High-stakes operations` — publishing, history rewrites, host skill
+  installation, and writing into a project Perry does not own.
+- **Evidence requirement**: every KR movement cites a command's output at
+  `evidence/2026-08/` or later, never a claim.
+
+## Cost Ceiling (phase #003)
+
+- Spend cap: **$0** in new paid APIs, models or infra. Perry is stdlib Python
+  and stays that way; a dependency is a decision, not an implementation detail.
+- Wiring status: **doc-only**. Nothing in code refuses an import.
+- ⚠ **Open risk, surfaced at every snapshot** per the goals-lane style rule:
+  the ceiling is a convention, not a guard. The one thing that makes it cheap
+  to hold is that the test suite already reads identically under
+  `PYTHONNOUSERSITE=1 /usr/bin/python3`, so a new dependency shows up as a red
+  suite rather than as silent drift.
+
+## User Commitments
+
+- **Decide the read-side promise for `.perry/config.md`.** `USER-903` settled
+  the *write* side — the file became a projection. `P003-O2-KR1` changes who
+  reads it: four call sites move from the markdown to `.perry/config.jsonl`.
+  `SKILL.md` promises the user owns that file directly, and this is the half of
+  that promise not yet decided.
+- **V5 sign-off on the adoption-reader fence** (`P003-O2-KR2`). It changes
+  which code path a foreign project goes through, and phase 002's carried DoD
+  item exists because that path has never been tested on a real project.
+- **Attribution answers for the 40 rows still never asked** (`P003-O3-KR1`). Perry
+  never guesses a KR; these can only be declared.
+- **`git push`.** `feat/work-modes` is several hundred commits ahead of
+  `origin/main`; the remote and CI have seen none of this phase's predecessor.
+- Phase scope-reduction trigger review, and phase-scoring participation.
+
+## User-Unavailable Degradation
+
+If user input is missing for >5 calendar days, work continues in this order:
+**TASK-209 → TASK-095 → TASK-099 → TASK-050 → TASK-199**. Objectives 1 and 2
+are fully reachable without the user.
+
+**Objective 3 stalls by design, and that is not a defect.** `P003-O3-KR1` is
+resolved by declaring an attribution, and `reference/okr-linkage.md` forbids
+guessing one. An agent that filled `unlinked[]` to clear the number would be
+recording a decision nobody made. New rows opened in the interim still take
+`P003-O3-KR2`'s gate, because declaring a row unlinked at `add` time is the
+author's own statement about their own row.
+
+## Phase Scope Reduction Rule
+
+- **KR-progress trigger**: if at phase day 10 the commit KRs of Objectives 1
+  and 2 are <50% achieved, Objective 3 collapses to its Must-Have — the
+  `add`-time linkage gate (`P003-O3-KR2`) — and the backfill of the existing
+  never-asked rows defers to phase 004.
+- **Phase-day trigger**: if by phase day 14 the read-side decision on
+  `.perry/config.md` is still open, `P003-O2-KR1` collapses to the two call
+  sites that are unambiguously internal (`bin/perry-state:139`,
+  `bin/perry-goals:2102`) and the two user-facing readers defer.
+
+---
+
+## Objective 1 — Every declared store exists, and one command checks all of them
+
+ADR-007's guarantee is only as wide as the census that checks it. Today the
+guarantee is checked for tasks and risks, unchecked for four, and the
+difference is invisible unless you read the tail of a lint run.

+
+**Two exclusions in `P003-O2-KR1`, both deliberate.** `bin/perry-tasks:1473`
+parses `BOARD.md` to *compare* it against the store — a drift check must read
+the rendered file by definition. `bin/perry-migrate:1177` / `:1188` parse a
+foreign project's board and OKR, which is what adoption is. Phase 002's
+`P002-O2-KR3` set a target of 0 parser lines and scored 0.68 against a number
+that could not have been reached, because `TASK-094` had already proved the
+adoption reader must stay. The exclusions are what make this target real.
+
+### Projects (seed for PMO TASK-IDs)
+
+- **TASK-095 — remove the parser for the three stores; keep what adoption needs**
+  - Owner: Coding Agent · User role: the read-side decision on `.perry/config.md`
+  - Deliverable: four `parse_tracks` call sites read `.perry/config.jsonl`
+  - Verification: the four named lines no longer call a markdown parser
+- **TASK-099 — sweep `bin/`, `viewer/` and `tests/` for handling ADR-007 made dead**

+  - Owner: Coding Agent · Deliverable: re-scoped to the adoption reader
+  - Verification: a mutation harness, not another regex
+- **TASK-199 — `BOARD.md` carries two truth models and nothing marks the boundary**
+  - Owner: Coding Agent · Verification: the boundary is readable from the file
+
+## Objective 3 — The phase's KRs cover the work that actually runs
+
+Phase 002 declared 13 tasks and the board ran 47. At scoring, **43 open rows
+resolved to no KR against 3 that did** — the phase's largest single signal, and
+the retro's own conclusion was that phase 003 must either declare KRs the live
+work serves or make the linkage step part of `add`. This Objective does both.
+Re-measured at phase start the set is **45**, not 43 — the board opened 14 rows
+between 002's scoring and this file. 43 is 002's number and is not carried.
+
+The number to drive to zero is not "unlinked rows". Work that serves no KR is a
+legitimate, declarable state. The number is rows in **neither** state — never
+linked, never declared — because that is the set nobody has ever been asked
+about.

+4. The adoption-reader guard exists **and has been shown to go red**.
+5. `perry-state --section attribution` reports 0 never-asked `main`-track rows.
+
+**Nice-to-Have** (failure allowed, explained in retro):
+
+6. `BOARD.md`'s truth-model boundary is marked in the file (TASK-199).
+7. `TASK-050`'s mutation harness replaces the regex round.
+
+## Not Doing in this phase
+
+- **Migrating gimegime-pmo or PolyForge** (`TASK-097`). Carried from phase
+  002's DoD item 5, not waived. The user decided on 2026-08-28 that the target
+  project's state is not suitable yet and the features land first. The
+  consequence stands and is worth restating: **phase 002's own argument — that
+  the abstraction survives contact with a real project — is still untested, and
+  phase 003 does not test it either.**
+- **The document class.** `design/*.md`, `DECISIONS.md`, `phase/*.md`,
+  `.perry/roles/*.md` stay documents, and Python keeps parsing them for now.
+- **Counting parser lines.** `P002-O2-KR3`'s target was unreachable by
+  construction; this phase measures call sites instead and says so in the KR.
+- **Raising the `BOARD.md` 200-line cap** to make room for intake. Phase 002's
+  queue-mode argument holds: an overflowing intake is a finding, not a cap
+  problem.
+
+## Process Note
+
+Cadence work — weekly status, handoffs, journal entries — lives under
+`BOARD.md § Cadence` and does not consume a phase Objective slot.
+
+Three intake rows are past the `intake` track's 5d SLA as of 2026-08-28:
+`TASK-139` (8d, over by 3), `TASK-155` (7d, over by 2), `TASK-157` (7d, over by
+2). They belong to `/perry work triage`, not to a phase Objective, and are
+noted here only so the phase is not planned as though the queue were empty.
+
+`TASK-157` — *plan-phase still authors the KR block by hand in a file
+documented as machine-written* — is about the command that wrote this file.

The author's measurement reproduces exactly. It added two things the RESULT does not say, and both strengthen the rejection: it would have been a REGRESSION rather than merely a non-fix, because shape 15, the whole table in a plain unnested fence, is already closed by round 1's broken toggle and the contiguous run HANDS IT BACK; and the obvious patch, 'only the first header run counts', is the same all-or-nothing failure section 1 rejects the whole-file fixed point for, reached by document order instead of by a stray line. Round 1's framing had a hole neither that reviewer nor the PMO saw. VERIFIED INDEPENDENTLY: the 21-shape catalogue cell-for-cell across three trees, six flips, nothing regressed, four legitimate rows still declaring, 09 and 12 confirmed fail-open on round 1; all 15 mutations on the reviewer's OWN harness with its own replacement lines, M9 through M13 each reddening exactly one named test, M1 disjoint from M2/M3, M14 reddening at the EXIT-CODE assertion; and the all-or-nothing replacement measured genuinely stronger rather than differently worded — one stray blank line voids all 23 of Perry's real declarations under a whole-file rule and 0 under the per-row rule.

-Adoption converts a project that has *no* Perry state. A different case turns up
-just as often: a project whose `BOARD.md`, `OKR.md` and `design/` already exist,
-written by hand or by an older Perry, in a shape today's readers cannot parse.
-ADR-004 says those files are **read-only until they migrate**, and this is where
-that happens.
+A section here used to cover *the project that already has state*: a
+`BOARD.md`, `OKR.md` and `design/` written by hand or by an older Perry, in a
+shape today's readers cannot parse. ADR-004 made those files **read-only until
+they migrated**, and `bin/perry-migrate` was the road out.
 
-**Do not do it by hand, and do not describe it here.** Run it:
+**All three of those things are gone** (`TASK-261`, `USER-910`). The ADR-004
+write gate is deleted, so nothing is read-only for want of a declaration any
+more — a writer that can render a file writes it. `perry-migrate` is deleted
+with it, because its output *was* the declaration: 2,393 lines that, across the
+whole life of this project, moved zero foreign projects. `.perry/conformance.jsonl`
+held 23 records and not one carried `route: migrate`.

-python3 "$PERRY_HOME/bin/perry-migrate" apply --root .    # writes, declares, names a restore point
-```
+If a project's files are in a shape Perry cannot read, the answer now is
+`/perry adopt` — which reads what is there as evidence and writes Perry's own
+state — or `perry-lint`, which names what does not parse. Neither pretends to
+convert somebody's file in place, and nothing refuses a write because a
+declaration is missing.
+
+**If foreign projects become a real goal**, the cheap shape is an *importer you

+recorded in `evidence/2026-08/2026-08-31-TASK-261-migration-fork.md`.
 
-Prose cannot assert that the id set before equals the id set after. The tool
-does — for every file, before it writes it — and refuses the file if it cannot.
-It also holds the rule this file's § "The one rule" states, in the one place it
-is hardest to hold: **the sections it creates are empty**. A project that files
-work under `## Open — 工程线` keeps that heading and every row under it; nothing
-is moved into `## P0`, because nothing in the file says which work is P0 and
-inferring it is exactly what this pipeline forbids.
-
-It asserts a second thing, which took longer to learn: **that the file still
-says what it said.** Every id, cell, character and row count can survive an edit
-that reverses the claim — a two-column legend under `## P0` widened into a task
-table, a `Status: not yet locked` normalized to `locked`, a token spliced into a
-sentence about a vendor contract. So the tool also re-reads its own output with
-`viewer/parsers` and refuses a file whose *records* changed, a line it rewrote
-that is neither a table row nor part of the header block, and a canonical value
-the author's own words — kept beside it — do not say. Each check names what it
-cannot see; `bin/perry-migrate § meaning()` is where that is written down.
-
-What the agent does around it:
-
-1. **Show the dry run.** All of it. It is the artifact the user is agreeing to.
-2. **Read back the files it will not touch**, and why. A file it refuses is
-   left byte-identical — an unresolvable status word, a table Perry does not
-   recognise, a file over its size cap. Each is one hand edit, and after it
-   `perry-migrate apply` finishes the job. "Does not recognise" is a
-   vocabulary test, not a shape one: a table is Perry's when more of the
-   schema's column names are already in its header than are missing from it.
-   `ID`, `Status` and `Owner` are the commonest words in any markdown table,
-   and sharing one of them is a coincidence.
-3. **Read the migrated files.** Not the diff — the files, as a reader. The
-   assertions above exist because three defects in a row passed thirty
-   mutations and were found by somebody opening the file, and each check states
-   its own blind spot precisely so this step still has something to do.
-4. **Never run `apply` without being asked.** ADR-004 § 4: mandatory migration
-   means the tool may refuse without it; it never means the tool may perform it
-   unasked.
-5. **Hand the restore point to the user by name.** `perry-migrate restore
-   <run-id>` puts every byte back, including the declarations the run made.

+### Prose in this file is layout, and `.perry/hook.md` is where it belongs
+
+**`.perry/config.md` is a projection of `.perry/config.jsonl`** (ADR-007,
+TASK-092). The store holds the preamble's `- Key: value` settings and every row
+of `## Tracks`; every other byte of the file is layout. `perry-config render`
+reproduces layout byte for byte **while a copy of the file is on disk to read it
+from**, and `perry-config render --write` rebuilds the whole file from the store
+alone when there is not — the shape above, the stored settings, the stored
+table, and nothing else.
+
+So the contract has two halves and only one of them is a promise:
+
+- **Settings and track rows are recoverable.** Delete the file and
+  `perry-config render --write` brings it back; every reader answers from the
+  store meanwhile, so nothing depends on the file existing (TASK-233).
+- **Prose is not.** It survives a render only while a file is there to copy it
+  out of, and that guarantee ends the first time the file is deleted, or a
+  project is cloned without it, or a fresh checkout renders before the file is
+  restored. It is not stored, on purpose:
+  [DESIGN-013](perry/design/DESIGN-013-one-place-per-fact.md) § 5.1 puts a
+  schema'd fact in exactly one store, and § 5.5 rejects moving prose into one by
+  name — a store is already a bad home for a paragraph.
+
+**Write the explanation in `.perry/hook.md` instead.** It is tier 1, it is
+yours, it is read at every standup by `/perry` and by every lane, and nothing
+renders it — so a render cannot destroy it and a deletion cannot lose it. Perry
+carries its own two configuration notes there, moved out of `.perry/config.md`
+on 2026-08-30 under `## Configuration notes`: what its `intake` track carries

-marker: *this file matches Perry's shape, at shape version N, and the user said

-was checked against, and the command that fixes it (`perry-conform declare` for
-a file that already matches Perry's shape, `perry-migrate` for one that does

-to make them write anyway and print what they found instead. **Reading is never
-gated in either mode**, and neither is `perry-migrate` — it is how an undeclared

-When a write prints a conformance line, **relay it and let the user decide.** Do

+### The two cost budgets — `Review rounds before escalation`, `Session context ceiling`
+
+Both are **measured defaults, not laws**, and both follow the precedence
+`Conformance gate` established: the environment beats this file, which beats
+the shipped value in `schema/state-schema.json § thresholds`. Every consumer
+reports which of the three answered, so a budget that stops work can be argued
+with by editing the register that actually set it.

+| `Session context ceiling` | 200000 | `PERRY_CONTEXT_CEILING` | `perry-context-budget`, and `autopilot` through it |

+bill is `Σ over turns (context at that turn)` and a long run is superlinear.
+Replaying those turns against a cap, 200k costs 58.3% less for the same work.
+
+Raise `Review rounds before escalation` for a project whose reviews genuinely
+converge by accretion; `1` makes every FAIL a decision point. Raise
+`Session context ceiling` for a project doing genuinely wide reads, knowing the
+cost of doing so does not grow linearly.

+It never caught anything. `.perry/conformance.jsonl` held 23 records at the
+end, all `route: declare`, all files in Perry's own repository: zero
+disagreements, because the disagreement the design exists to surface needs a
+foreign project that drifts and Perry has never been pointed at one. The gate,
+its ledger, `bin/perry-conform` and `bin/perry-migrate` are all deleted.
+
+**What this changes for you**: nothing refuses a write for want of a
+declaration. A writer that can render a file writes it. `perry-lint` still says
+whether a file matches the schema — that half was never the gate.
+
+A `- Conformance gate:` line left in an existing `.perry/config.md` is inert.

It is also what makes the conversion possible at all - the file gates every write under ADR-004's enforce gate INCLUDING the write that migrates it, and the migration needs no exemption because no writer has ever called the gate about a file that is not a files[] entry. An exemption would have been a hole; this is a file the gate has no opinion about. IT IS NOT A claims[] ENTRY OF ITS OWN EITHER, and that is a separate question with its own answer rather than the same one. claims[] asks what territory Perry occupies in someone else's project, and .perry/ is already claimed as a dir - so the store is covered, exactly as the markdown was, and tests/test_conformance.py section 9 measures that declaring conformance does not make Perry collide with itself. .perry/events.jsonl and .perry/config.jsonl are named individually inside that same territory, which tests/test_claims.py reads as naming rather than coverage - 'it adds no second immovable place, it names a file in the immovable one'. So a seventh entry would add nothing the collision check can see, and it would add a seventh store to the six that perry/phase/003-linkage.md's KR1, KR2 and KR3 are each phrased 'of 6' over.

+"""**Planted spellings for `tests/sweep_handed_back_commands.py`.**
+
+Never imported and never run. Only ever PARSED, by the sweep and by
+`tests/test_conformance.py § TestTheSweepIsMeasuredNotTrusted`, which is what
+turns the sweep's recall from a sentence in a RESULT into a number the suite
+recomputes.
+
+The V4 round-4 reviewer measured the round-4 sweep at **10 found of 15**
+plausible spellings, in a file of its own that no longer exists. A recall
+number nobody can re-derive is a claim, so the fifteen are planted here with
+the reviewer's own descriptions, plus the shapes round 5 added a rule for.
+
+One function per spelling. The suffix is the measured verdict, and the test
+asserts it both ways:
+
+* `_found`   — the sweep reports at least one problem inside this function.
+* `_missed`  — it reports none, and that is a **blind spot**: the command is
+               genuinely handed back with the root dropped or a value
+               interpolated raw, and the sweep cannot see it. Each says why.
+* `_clean`   — it reports none, and that is **correct**: the phrase is a
+               mention, a provenance value, or a properly built command. These
+               guard the other direction, where a sweep that called everything
+               a finding would also score 100 % recall.
+
+Nothing here is a defect in Perry. `perry-conform` and `perry-migrate` are
+both at zero; this file exists so the *sweep* can be measured.

-"""The conformance gate's opt-out line, for fixtures that are not about it.
-
-TASK-047 flipped `bin/perry-conform.DEFAULT_MODE` from `advisory` to `enforce`,
-so a writer now REFUSES a state file nobody has declared. That is the shipped
-behaviour and `tests/test_conformance.py § 7` is where it is asserted.
-
-Every other suite in here builds a throwaway project and then tests something
-that has nothing to do with ADR-004 — how a row is rendered, whether a widening
-loses a cell, what `--dry-run` prints. Those fixtures are undeclared, because
-nobody declared them, so after the flip every one of their writes was refused
-and fifteen modules went red at once. The refusals were correct; the fixtures
-were simply answering a question they were not asked.
-
-**Why the opt-out and not a declaration.** Declaring would be the more faithful
-fixture — a real adopted project IS declared, and Perry's own repo is 13/16 —
-and for a clean fixture it would work. It cannot be the general answer here:
-a large share of these fixtures are *deliberately malformed*, which is the whole
-point of the suite that owns them (`test_prioritize` widens a board with 4 shape
-errors; `test_row_integrity` corrupts rows on purpose). `perry-conform declare`
-correctly refuses a file that does not match Perry's shape, so those fixtures
-cannot be declared by construction. One control has to cover both kinds, and
-`- Conformance gate: advisory` is the one the user has for exactly this reason.
-
-This is NOT a way to keep the suite from meeting the gate. It is a per-fixture
-statement that a given project is out of scope for ADR-004, written in the same
-documented, user-facing control a real project would use. The gate itself —
-both branches, both precedence paths, both exemptions — is exercised in
-`tests/test_conformance.py`, and `tests/test_work_modes.py` still declares a
-`.perry/config.md` for real rather than opting out.
-
-Usage — append it to whatever the fixture already writes:
-
-    (root / ".perry" / "config.md").write_text(
-        "# Perry configuration\\n\\n- State root: .\\n" + GATE_OFF)

+`tests/test_conformance.py` and `tests/test_migrate.py` both assert that a

+rule — an extractor and a substring assertion in one, a hand-written

+whether the phrase was a command line.
+
+The rule lives here so there is one of it.  `tests/sweep_handed_back_commands.py`
+is the other half — this module reads what a message PRINTED, that one reads

+"""The one-header-rule check. TASK-050 round 9 — **one net, over a symbol.**
+
+Rounds 2 through 7 each shipped a better DETECTOR of a second header rule and
+each was defeated within one review:
+
+    round 2  three copies in files that never imported `squash`
+    round 3  a SUBDIRECTORY was invisible; the pattern matched a SPELLING
+    round 4  the `[` had to sit right after the `=`; and `_is_python` trusted
+             the extension, so the same bytes were green without a shebang
+    round 5  it knew `split_row(` and not the private splitter `.split("|")`
+    round 5's REVIEW  nine planted spellings, FIVE escaped both nets
+    round 6  the regex became an AST walk
+    round 7's REVIEW  the walk's GATE is still an eleven-name allowlist of
+             variable names: `[squash(c) for c in prev_cells]` at
+             viewer/parsers.py could be reverted to the historical rule,
+             silently drop a KR out of a user's OKR, and leave 2882 tests green
+    round 8   kept the defeated shape net ALONGSIDE the symbol check, and the
+             shape net promptly reported correct code — a value normalizer
+             appended to `bin/perry-explain` turned `bash tests/run` red and one
+             of the two failing tests was named
+             `test_value_normalizers_are_not_flagged`
+
+**Round 9 deleted the shape net.** Not because it was unfinished — because
+finishing it is the thing seven rounds proved cannot be done, and keeping it
+next to the check that replaces it is what put a false positive in front of
+correct code. What is left is one net, and it is the one the amendment asks
+for:
+
+## The net. `offenders_by_symbol()`
+
+*Nothing outside `viewer/tables.py § header_index` applies `squash` (or its
+`norm` alias) to a header row or to a cell of one.*
+
+It is the drift half — the same rule, copied — and it is the half the design
+makes decidable, because after round 8's conversion the tree contains **zero**
+such sites. The check is an equality against zero over one symbol.
+
+It holds **no allowlist of variable names of any kind**. A row is what
+`split_row` or `header_index` produced, followed through local dataflow:
+assignment, aliasing, slicing, subscript, a walrus, an iterable wrapper, one
+element-preserving comprehension unwrap, a parameter this file passes a row to,
+and what a file-local function RETURNS. `ROW_NAMES` (eleven variable names) and
+the `("header", "headers", "hdr")` subscript test are **deleted**; `BLESSED` and
+`ROW_PRODUCERS` name FUNCTIONS this repository is allowed to have, which is the
+design and not a spelling.
+
+It cannot fire on a value normalizer, because a value normalizer folds a value
+and not a row — that is not an exception carved out for it, it is what the two
+words mean. Round 8's declared false positive came from treating any
+`.split("|")` as a row source, which cannot tell `line.split("|")` from
+`cell.split("|")`. **That inference is gone.** Criterion 3's own guard —
+`tests/test_row_integrity.py § test_no_tool_splits_a_row_on_a_raw_pipe` —
+already forbids a bare `.split("|")` anywhere in `bin/` or `viewer/`, so
+nothing here needs to guess about one.
+
+## What this net does NOT see, and what covers it instead
+
+**A reader that invents its OWN rule** — `[c.strip("*` ").lower() for c in
+cells]` — calls no blessed symbol, so this net is blind to it by construction.
+That class is the whole of `tests/test_header_rule_harness.py § SECOND_RULE`,
+which plants every shape the round 5 and round 7 reviews name (each entry
+quoting the review line it comes from) and **asserts that it escapes**, so the
+limit is a measured number rather than a claim.
+
+What covers that class is not a net:
+
+1. `viewer/tables.py § header_index` is the only function that folds a header
+   cell, so there is nothing for a second rule to be a second copy OF; and
+2. `tests/test_header_index_is_the_only_fold.py` watches the real readers parse
+   a real decorated document and asks both *who folded a header cell* and *did
+   every decorated header cell reach `header_index`*. A reader that grows its
+   own rule stops reaching it, and that test goes red.
+
+Its limit is stated there and measured there: it sees the readers a parse
+reaches, and the module reports exactly which readers those are, with fold
+counts, rather than listing readers it never observes.

+## TASK-230: the clock, and the one rule that keeps it from lying
+
+The suite reached 99 modules / 2904 tests and a routine full run stopped being
+a nuisance and started producing wrong outcomes: on 2026-08-28 two dispatches
+were killed by a 600-second no-progress watchdog **at the moment they kicked
+off the suite**, and their finished work had to be recovered by hand.
+
+Three things changed here, and the third is the only one that could ever have
+altered a verdict, so it is the one with a guard on it.
+
+**1. Longest module first, and it is the whole speedup.** With 99 modules and
+one worker pool the makespan is `max(longest module, total / workers)` only if
+the long modules START early. Alphabetical order does not know which those are,
+and on this suite it is close to worst case: the three most expensive modules —
+`test_task_writer`, `test_store_drift` and `test_store_is_canonical` — sit at
+alphabetical positions **91, 84 and 85 of 99**, so eight workers spend the run
+on short modules and then draw the longest one with nothing left to overlap it
+with.
+
+Measured 2026-08-30 on a machine that was NOT quiet (another agent's suite runs
+held the load average between 17 and 65 all night, and single measurements
+swung by 2x — see `perry/evidence/2026-08/TASK-230-result.md`). Twelve full
+runs, alternating the two schedules so the load drifted across both arms:
+
+    alphabetical  (5 runs)  179.8  184.4  188.4  203.1  241.1   median 188.4s
+    longest-first (7 runs)  133.1  140.1  149.2  149.7  171.9  247.0  285.0
+                                                            median 149.7s
+
+Wall-clock under that much foreign load is not a measurement, so the arms were
+also compared **against each run's own per-module costs**, which removes the
+drift: for each of four `--times` runs, what would the OTHER schedule have cost
+on exactly these module times?
+
+    run         alphabetical    longest-first   best possible   floor
+    t-alpha-1        179.7            120.1           120.1     120.1
+    t-hint-1         222.9            140.0           140.0     140.0
+    t-alpha-2        241.1            155.4           154.5     154.5
+    t-hint-2         210.4            133.1           133.1     133.1
+
+**The model is validated by two of those four runs, not four.** In the two
+longest-first runs the longest module started at t=0 and ran to the end, so
+`simulated == max(module time) == measured wall` is an arithmetic identity and
+predicts nothing. The two ALPHABETICAL runs are the real check — there the
+makespan is a bin-packing of 99 modules across 8 workers that could have come
+out anywhere, and it came out 179.7 against a measured 179.8, and 241.1 against
+a measured 241.1. The saving is **33-37%**, and `tests/durations.json` — whose recorded
+values are 3-4x too large, because they were taken under that same foreign load
+— still produces a schedule equal to the perfect-knowledge one in three runs of
+four and within 0.9s in the fourth. That is the hint doing the only job it has.
+
+Total CPU is unchanged and says so: `user+sys` came to ~500s alphabetical and
+~480s longest-first. The same work, finishing sooner.
+
+`tests/durations.json` records what each module cost last time and the pool is
+fed in descending order of it. Modules with no recorded time sort **first**: an
+unknown module is assumed slow, because the cost of guessing wrong that way is
+a slightly worse schedule and the cost of guessing wrong the other way is the
+new module landing last — the very pathology above.
+
+**2. The worker count is deliberately NOT raised, and that is a measurement.**
+`min(8, cpu_count())` looks like a leftover from when there were 34 modules,
+and raising it to 14 on this 14-core machine was the obvious change. It buys
+**nothing**: the `floor` column above is `max(longest module, total/workers)`
+and it equals the longest module in all four runs, so once the schedule is
+longest-first the binding constraint is no longer how many modules run at once
+— it is `test_task_writer.py` running alone for two minutes. More workers past
+that point buy zero seconds and cost real contention, and this suite has a
+concurrency test (`test_host_support.TestOpenCodeDispatchLimit`) that is
+already known to flake under it. **A faster-looking suite that flakes is a
+worse gate than a slow one**, so the number stays where it is until the floor
+moves. Moving it means splitting `test_task_writer.py`, which is a different
+row: sharding below the file changes the isolation boundary the fixtures
+assume, and this row deliberately did not do it.
+
+**3. `--ids` writes the pass/fail SET, not just its size.** The zero-test guard
+catches a module that stopped loading. It does not catch a module that loaded
+and ran *fewer* tests than it used to — which is the same failure wearing a
+smaller hat. Diffing the id set between two runs catches both, and it is what
+a change to this runner has to be verified against.
+
+**And the set has to be able to prove it is the whole set.** The first version
+of `parse_ids` returned 2885 ids for 2899 tests and said nothing; `--ids` now
+refuses to write a file whose id count disagrees with unittest's own `Ran N`.
+See `parse_ids`.
+
+**The rule the schedule obeys: a hint may reorder the work, never select it.**
+`tests/durations.json` is a **sort key over the glob's own result** and is used
+nowhere else. A stale entry, a missing entry, an entry for a module that no
+longer exists, or the whole file being absent or corrupt changes the ORDER the
+modules run in and cannot change WHICH modules run. That is asserted directly
+in `tests/test_parallel_runner.py`, because a scheduling file that can silently
+drop a module is exactly the "the number was still large enough to look right"
+defect this runner already has one scar from.

+# ── step 0a: the environment the guard can see ─────────────────────────
+# **The guard hashes $ROOT and only $ROOT, so every write has to be aimed at
+# $ROOT for it to see them.** `perry-task` resolves its project root from
+# $PERRY_PROJECT BEFORE falling back to the cwd, so a suite run in a worktree
+# by an agent that has $PERRY_PROJECT exported at the main checkout sends
+# every un-rooted write into that OTHER tree — four files move over there
+# while step 0 truthfully reports this one unmoved. Several worktrees are live
+# on this machine and a PERRY_PROJECT/PERRY_HOME mismatch has already cost one
+# agent a check that appeared to refute its own reviewer.
+#
+# So the suite REFUSES to start in that environment. It does not quietly
+# re-point the variable: exporting PERRY_PROJECT="$ROOT" was tried first and
+# reddens nine tests in `test_config_store_readers` that depend on the variable
+# being ABSENT so the cwd walk runs — a guard that has to bend the suite to fit
+# is a guard that will be bent back. Refusing costs nothing, because after it
+# the only two reachable states are "unset" (perry-task falls back to the cwd,
+# which `cd "$ROOT"` above just set) and "equal to $ROOT". Both land inside the
+# tree step 0 hashes.
+#
+# **"Equal" has to mean the same DIRECTORY, not the same string.** The first
+# version compared the raw string against `pwd -P` and refused two environments
+# that are in fact this very tree: a /tmp symlink alias of $ROOT, and $ROOT
+# with a trailing slash. Both would have written inside the tree step 0 hashes,
+# and both were turned away — a false refusal in a guard whose whole argument
+# is that refusing costs nothing. Resolving with `cd … && pwd -P` closed those
+# two and left a third: `pwd -P` collapses symlinks but does NOT canonicalise
+# case, and neither does `Path.resolve()`, so on this case-insensitive
+# filesystem $ROOT spelled in another case `cd`s into the same real directory
+# and was still refused (round-3 V4, sharp edge A).
+#
+# So the comparison is `test A -ef B` — same device, same inode. That is the
+# question actually being asked: would an un-rooted write land inside the tree
+# step 0 hashes? It answers yes for the symlink alias, the trailing slash, the
+# doubled slash, `$ROOT/.`, `$ROOT/tests/..` and any casing the filesystem
+# resolves to $ROOT, and no for everything else. A path that does not exist has
+# no inode and is refused — correctly, because `perry-task` would go on to
+# create it. `PERRY_PROJECT_REAL` is still computed, for the message only.
+#
+# **A RELATIVE value is refused before the comparison is even reached, and
+# that is a decision rather than a side effect.** `cd … && pwd -P` accepted `.`
+# and `tests/..`, which the raw comparison at 8dfd25e had refused; so did
+# `-ef`, since this script has already `cd`ed to $ROOT. Accepting them is
+# wrong: a relative PERRY_PROJECT names a different directory to every process
+# that reads it. This script would resolve it against ITS cwd; `perry-task`
+# resolves it against each subprocess's, and tests routinely pass `cwd=` a temp
+# directory. A value this script certifies as "this tree" is therefore a value
+# `perry-task` may read as another tree, which is the exact hazard step 0a
+# exists to close. Refusing costs a `env -u PERRY_PROJECT` and removes the
+# whole class.

+r"""Does every message that HANDS THE READER A COMMAND name it with the root
+the reader used?  (TASK-234 round 4.)
+
+The class this sweeps for, stated as the defect that produced it:
+
+    `bin/perry-conform § message_for` propagates the invocation's `--root`
+    into every branch through `_root_flag()`.  `migrate_record`'s two refusals
+    did not.  A reader routed there by `perry-conform migrate --root $PROJ`,
+    who copied the command they were handed, got `rc=0` and *"nothing to
+    convert — `.perry/conformance.jsonl` is already this project's record (or
+    it has none)"* — about whatever project they were standing in, while their
+    own record sat unconverted and still gating every write.  Not an error: a
+    success-shaped silence, which is the worst thing a refusal whose whole job
+    is to hand back a working command can do.
+
+`bin/perry-conform`'s members are pinned by
+`tests/test_conformance.py § test_no_refusal_in_perry_conform_names_a_command
+_without_the_root`, which runs this same rule as part of the suite.  This
+script is the sweep over the WIDER tree, where the remaining members are and
+where they are recorded rather than fixed (`TASK-234-result.md § 10.9`).
+
+**Round 5 adds the second half of the class.**  Round 4 asked only *does the
+phrase carry the root*.  The round-4 V4 FAIL carried it — and spelled it
+`--root /Users/ada/My Project`, which the reader cannot run.  So a handed-back
+command is now also read for HOW its arguments got there: every `{...}` inside
+one has to be a spelling that is shell-safe by construction (`_q(...)`,
+`_root_flag(...)`, `shlex.quote(...)`, or the `r` those produce), and a raw
+`{v.path}` or `{root_arg}` is reported as `UNQUOTED`.
+
+That rule cannot see the round-4 defect at its ORIGIN, because `_root_flag`'s
+own body is `f" --root {root_arg}"` and contains no tool name for `CMD` to
+match.  `FLAG_VALUE` is the rule for that: a long flag whose value is
+interpolated raw, in any non-docstring template, command phrase or not.
+
+    python3 tests/sweep_handed_back_commands.py [--all] <file> [...]
+
+Exit 1 if any handed-back command lacks the root or interpolates a value raw.
+`--all` lists every phrase with its ruling, so the ruling itself can be
+audited rather than trusted.
+
+**Read off the AST, not by grepping.**  A comment or docstring discussing this
+very defect is not a finding, and a message assembled from implicit or `+`
+concatenation is one string, not three.  Each `{expr}` is rendered as itself so
+`{r}` and `{_root_flag(root_arg)}` are visible in the template.
+
+**The blind spot, stated rather than left to be discovered.**  The ruling is
+made from the text immediately before the phrase, so a command built somewhere
+with no cue and interpolated into a message far away is read as a mention.  One
+such site exists today — `bin/perry-migrate § rollback_message`, which assigns
+to `cmd` — and `NAMED_AS_COMMAND` catches that shape by the variable's name.
+A third shape (built into a name that says nothing, e.g. `s = "perry-x …"`)
+would still be missed; there is none in this tree, checked by
+`grep -rn 'cmd = f\?"perry-\|command = f\?"perry-' bin/ viewer/`, and a sweep
+that claimed otherwise would be claiming more than it measures.

+"""`attribution`'s three buckets are disjoint. TASK-228.
+
+`perry-state --section attribution` reports `linked`, `unlinked` and
+`declared_unlinked`. `unlinked` was built by asking "did this row resolve to a
+KR?" — which is false for a **declared** row as much as an undeclared one, so
+every id in the register's `unlinked[]` was reported in BOTH buckets.
+
+Measured 2026-08-28 on Perry's own board, after declaring 48 rows:
+`linked=8, unlinked=48, declared_unlinked=48`, and the two sets were
+byte-identical.
+
+**It is not a cosmetic double-count.** `unlinked` is the number a standup
+renders as *"N tasks awaiting KR attribution"*. On 2026-08-29 it was read off
+this payload and reported to the user as 52 rows owing an answer — when the
+true never-asked count was **0**. Every one of those answers had been given the
+day before, through `perry-goals link --unlinked`, with the user's consent. The
+payload turned finished work into outstanding work, and the person it misled
+was the person who had done it.
+
+`reference/okr-linkage.md` had it right all along: *"`linked`, `unlinked`
+(couldn't resolve), and `declared_unlinked` (the graph says outright that this
+work serves no KR)"*. The document described three states and the code
+implemented two. This module is the agreement between them.
+
+**Why the never-asked reading is the load-bearing one.**
+`phase/003-storage-code.md § P003-O3-KR1` drives to zero *"open `main`-track
+rows in neither `objectives[].krs[].tasks[]` nor a declared `unlinked[]` — the
+never-asked state"*, and says in as many words that work serving no KR is a
+legitimate declarable state. A bucket folding the declared into the unresolved
+makes that KR unmeasurable from the very payload it is defined against.
+
+**The fixture is `tests/fixtures/sample-project`, copied**, not hand-built. It
+already carries the exact shape under test — `REL-001`/`REL-002` linked,
+`REL-009` declared `unlinked` — so the case is real rather than constructed,
+and a fixture that drifts breaks this module loudly instead of quietly
+asserting nothing. The first draft of this file DID hand-build a board; it
+produced `linked: 0, unlinked: []` because no row parsed at all, and every
+assertion in it passed vacuously on an empty set.

-"""TASK-043's gate: the declared, checkable conformance marker (ADR-004).
-
-The claim under test: **Perry can tell "this file matches my shape, at shape
-version N, and the user said so" apart from "this folder has a BOARD.md in
-it"** — and every writer asks the first question about the one file it is
-about to write, while every reader asks neither.
-
-Two things this suite is deliberately built to catch, because they are the
-failure modes the task's own rubric names:
-
-- a gate that cannot fire — and, since TASK-047 flipped the shipped default to
-  `enforce`, a gate that cannot be turned off. Both branches are exercised
-  explicitly: § 7 asserts the refusal under the shipped default AND the write
-  proceeding under `advisory`, reached both by `PERRY_CONFORMANCE` and by
-  `.perry/config.md`. A guard that only ever runs in one mode is not a guard.
-- a second definition of Perry's shape. `TestOneDefinitionOfTheShape` compares
-  `perry-conform`'s per-file error counts against `perry-lint`'s own findings,
-  file by file, on `tests/fixtures/witness-project` — a project in the
-  repository, read through `--root`, whose findings are constructed rather
-  than captured. They agree because there is one implementation; if someone
-  writes a second one, this goes red.

-
-
-#: The corpus for § 6, and it is inside the repository on every machine.
-#:
-#: It used to be `~/proj/gimegime-pmo`, behind `PERRY_TEST_CORPUS` and an
-#: `if (REAL / "BOARD.md").exists()` in `setUpClass`. On the author's machine
-#: the four tests below ran; on every other checkout they skipped, so the "one
-#: definition of the shape" claim — the thing this section exists to hold —
-#: had no coverage anywhere it mattered. TASK-111's sweep named this file and
-#: left it its own row; TASK-124 is that row.
-#:
-#: `tests/fixtures/witness-project` (TASK-132) replaces it, read through the
-#: **same `--root` seam** the real project was read through. It is not a
-#: snapshot of anybody's project: every finding in it is constructed, one per
-#: rule, and its own top-risk line says so. And nothing below asserts what
-#: those findings ARE — the assertions are that `perry-conform` and
-#: `perry-lint` report the *same* per-file error counts, whatever the fixture
-#: happens to carry. A golden file recording what one real project looked like
-#: on capture day is the failure TASK-145 spent a row escaping; this is the
-#: other shape, where correctness is a property of the two checkers and the
-#: fixture only has to be non-trivial.
-#:
-#: `PERRY_TEST_CORPUS` is gone. It was a way to point these tests at a
-#: different directory, and the only thing it ever pointed them at was the one
-#: directory that is now unnecessary; keeping it would leave a second, untested
-#: way for this corpus to become something else.

+"""`perry-context-budget` — the gate that makes a long run affordable.
+
+Measured across 25 Perry sessions and 18,941 turns: **8.43 billion tokens, 99.1%
+of it `cache_read`** — the accumulated context, re-read on every turn. Output
+was 0.3%. The largest session ran 8,174 turns at a mean context of 504,651 and
+peaked at 997,717.
+
+Cost is therefore `Σ over turns (context at that turn)`, and both factors grow
+together inside one session. Replaying the measured turns against a cap: 200k
+would have cost **58.3% less** for exactly the same work.
+
+This is the check that the gate reads the host's own accounting rather than
+guessing, trips at the ceiling, and — the one that matters most — **abstains
+loudly instead of passing silently** when it cannot measure. A gate that
+returns "fine" because it found nothing to look at is worse than no gate.

+to tell its caller what it does not know.
+
+**Half one — an unknown subcommand.** Filed as "exits 0, so a typo silently
+disables the concurrency cap". Re-measured 2026-08-29: it already exits 2 and
+prints the usage, so that half was fixed before this row was worked. It is
+pinned here rather than deleted — an exit code nobody asserts is one a later
+refactor can drop, and the row's own Verification names this call.
+
+**Half two — `list` reports bookkeeping, not observation.** Live, and the
+expensive one. A marker is a file this tool wrote; nothing in it observes a
+process. `registered_pid` looks like it would let you check, and it does not:
+it is the pid of `perry-dispatch-limit` ITSELF at `register` time, and that
+process exits within milliseconds. `kill -0` on it reports "dead" for every
+marker ever written, including one whose agent is alive and working.
+
+Both failure directions are real and Perry has hit both:
+
+- 2026-08-28 — an ESC killed two agents whose slots stayed reserved; and a slot
+  was reserved for a dispatch call that was never made, leaving 20 minutes of a
+  phantom in-flight row.
+- 2026-08-29 — `TASK-095` and `TASK-209` both read "dispatched; awaiting
+  RESULT" while this tool reported **0 in flight** and both deliverables were
+  already merged into `main`.
+
+Three instances in two days, every one caught by a human reading two numbers
+side by side. The row's deliverable was "list reports observation, or says
+plainly that it reports bookkeeping and observes no process". Observation is
+not available at this layer — the pid is not a handle and the tool never learns
+the agent's — so it says so.
+
+**The note goes to stderr on purpose.** This file's own convention, stated at
+`clean_stale`: *"`check` and `list` have parseable stdout and a warning is not
+part of their answer."* `TestStdoutStaysParseable` is that rule.

+"""The planting corpus for the one-header-rule check. TASK-050, round 9.
+
+**Three reviewers have now defeated this file's corpus, and the third defeated
+it by AUDIT rather than by planting.** Round 5 planted nine spellings and five
+escaped both nets; round 7 planted twenty-five and twenty-one escaped; round 8
+reported *"30 of 30 caught"* against a corpus it described as *"the UNION of
+every shape the round 5 and round 7 reviews name"* and *"a superset of round
+7's corpus"* — and it was neither. Round 7's own escape list names *"a scalar
+header-row test"* and *"P23–P25, round 4's `_is_python` hole"*; **none of them
+was in the corpus**, and the labels `P23`–`P25` had been re-used for three
+different shapes, so the omission was invisible in the numbering. The reviewer
+re-derived the missing shapes, planted them with a control at the same paths,
+and all five escaped both nets.
+
+So this file is rebuilt, and it is rebuilt under three rules:
+
+1. **Every entry quotes the review line it comes from.** The `source` field is
+   not decoration — it is what makes the denominator auditable instead of
+   asserted. An entry with no quote cannot be checked against the review that
+   produced it, and `test_every_entry_carries_its_provenance` refuses one.
+2. **A label is never re-used for a different shape.** That is the specific
+   mechanism that hid round 8's pruning, and
+   `test_no_label_is_re_used_for_a_different_shape` asserts it directly.
+3. **What escapes is a corpus too, with the same provenance.** Round 8 reported
+   a fraction against the shapes it caught. This reports three fractions, and
+   the one that is zero is the one that matters most to read.
+
+## The three corpora, and what each measures
+
+- `DRIFT` — **the net's own class**: the ONE rule (`squash`, or its `norm`
+  alias) applied to a header row, or to a cell of one, outside
+  `viewer/tables.py § header_index`. This is what
+  `tests/header_rule.py § offenders_by_symbol` exists to see and every entry
+  must be caught.
+- `CLEAN` — legitimate code that must never be reported. Criterion 4 of the
+  spec is this list, and round 7 failed it six times out of eight.
+- `SECOND_RULE` — **every shape the round 4, 5 and 7 reviews name, and it is
+  asserted to ESCAPE.** A reader that invents its own rule calls no blessed
+  symbol, so the symbol check is blind to it *by construction*. That is a
+  declared limit, not a defect to be fixed by an eighth detector: seven rounds
+  proved the shape net cannot be finished, and round 8 proved that keeping an
+  unfinished one next to the symbol check puts a false positive in front of
+  correct code. What covers this class is
+  `tests/test_header_index_is_the_only_fold.py`, which watches the real readers
+  parse a decorated document and asks whether every decorated header cell
+  reached `header_index` — a reader that grows its own rule stops reaching it.
+
+**Round 8's shape net (`offenders`) is deleted.** With it went `ROW_NAMES`
+(eleven variable names), the `("header", "headers", "hdr")` subscript test, and
+the `.split("|")` row inference that produced the declared false positive. No
+allowlist of variable names survives anywhere in `tests/header_rule.py`.
+
+Everything is planted into a `tempfile` COPY.
+`work/reference/review-constraints.md` is explicit: for the seconds a planted
+file exists, a shared checkout has a file that makes this guard legitimately
+red, and anything else running the suite sees a real-looking failure about
+nothing.

+**2026-08-29** — thirteen days stale on a file `perry-task` re-renders dozens of

+on disk. A renderer that stamped today's date would report the board as drifted

+alone. `TestARenderIsNotAWrite` is that distinction.

-"""TASK-044: migration is dry-runnable, lossless, recoverable, and declared.
-
-The claim under test: **a project can be brought to Perry's shape by a program
-whose preview cannot diverge from what it does, which refuses rather than lose
-a character of somebody's writing, which can be undone, and which never runs
-unasked.**
-
-Three of ADR-004's five guarantees are assertions, and an assertion an agent
-performs by reading is not one. So the shape of this suite is deliberate:
-
-- the losslessness tests run against a board that Perry did NOT write. A board
-  Perry generated is already Perry-shaped and proves nothing; `LEGACY_BOARD`
-  below is modelled on `~/proj/gimegime-pmo` — work filed under headings its
-  author chose, a four-column priority table, a status word Perry has no value
-  for, and prose in a cell the schema has nowhere to put.
-- `TestDryRunIsTheRealRun` compares bytes, not intentions.
-- `TestRecoverable` exercises the recovery path rather than describing it.

+"""`tests/parallel`'s scheduling hint may reorder the work. It may never select it.
+
+TASK-230 gave the runner a stopwatch (`tests/durations.json`) so the long
+modules start first. That file is written by a previous run, is not validated
+by anything, and lands in the same repository as the modules it names — so the
+question this module exists to answer is not "does it make the suite faster"
+but **"what is the worst thing a wrong one can do?"**
+
+The answer has to be "a worse schedule", and it has to stay that way, because
+this runner already carries a scar from the other answer. Its first version
+shelled out to `python3 -m unittest tests.<name>`, which does not put `tests/`
+on `sys.path`; eighty tests stopped running, the total came back 1207 against
+1287, and **the number was still large enough to look right**. A scheduling
+file that can drop a module reintroduces exactly that failure with a more
+respectable-looking cause.
+
+So `schedule()` is asserted to be a permutation — same length, same membership
+— under every way the hint can be wrong: absent, stale, naming modules that do
+not exist, missing modules that do, holding the wrong types, or being garbage
+that does not parse. None of those may change WHICH modules run.

+"""**An ordinary write may never SHRINK a canonical store.** TASK-203, USER-906.
+
+Three rounds of TASK-203 shipped three different predicates — the command name,
+an identity tuple, the section's shape — and all three ended in the same
+defect: an ordinary command silently truncating a canonical register store at
+exit code 0, with `perry-lint` reporting the wreck as `0 row(s) drifted`. The
+user answered USER-906 with option B, which is not a fourth predicate:
+
+    Only `purge`, `resolve-intake` and `intake-sweep` may reduce a record
+    count. Any derivation producing fewer records than the store already holds
+    is a REFUSAL, not a write.
+
+The order of this file is the argument.
+
+1. **The fixtures are asserted to be the shape under test, before anything is
+   asserted about behaviour.** Round 3 shipped a `foreign`-shape test whose
+   legend table landed under `## Top risks` because `ensure_section` anchors
+   `## Intake` before `## P0`, so the section was never foreign and the test
+   was green with the guard reverted. Every board this module builds is
+   handed to `perry_store`'s own shape function and the answer is asserted.
+
+2. **The reproduction from `evidence/2026-08/TASK-203-merge-hold.md`**, which
+   is this row's reason to exist: 3 records to 0 on `perry-task add --track
+   ops` with `## Intake` absent.
+
+3. **The four doors**, each named for the round that found it.
+
+4. **The three commands that may still shrink**, because an invariant that
+   also blocks the sweep has broken the register rather than protected it.

+    this repository's own intake data: `resolve-intake`, which removes no
+    record at all, took `perry/intake.jsonl` from 11781 bytes / 28 records to

+"""**A count-preserving substitution destroys canonical records.** TASK-243.
+
+`refuse_to_shrink` is a COUNT rule and USER-906 chose it as one. 32 records to
+32 records is not fewer, so the invariant is silent, and it is right to be:
+this module adds no predicate to it and asserts, behaviourally, that none was
+added (`TestTheInvariantIsStillACountRule`).
+
+The question here is IDENTITY. Swap N rows of a register on the board by hand
+— same count, different rows — and any register-touching command persists the
+swap. Measured 2026-08-30 on this repository's own state:
+
+    intake  · resolve-intake   10 lost, 10 gained, rc 0, 10 drifted → 0 drifted
+    intake  · intake           10 lost, 11 gained, rc 0, 10 drifted → 0 drifted
+    asks    · ask               3 lost,  4 gained, rc 0,  6 drifted → 0 drifted
+    risks   · risk-add          2 lost,  3 gained, rc 0,  4 drifted → 0 drifted
+    zh      · ask          USER-014 lost,          rc 0,  2 drifted → 0 drifted
+
+**The ending this row chose is REPORT, not refuse**, and the choice is forced
+rather than conventional. On `## Intake` a record's identity IS its text, so
+fixing a typo in a Request cell and swapping a row out from under a stored
+record are the same edit at the set level. A refusal would hard-block the typo
+fix and name `perry-tasks intake-write --from-board` as the remedy for it,
+which is TASK-095 round 5's defect exactly. A tool that cannot tell the two
+apart must say what it sees.
+
+**The property, and it is falsifiable on its own:** no canonical record leaves
+a register store unreported. Before this change the operator's sequence was
+`10 drifted → (silence) → 0 drifted`; the silence is the defect, and every test
+in § 2 asserts against the number the write itself prints.
+
+**Every board in this module is one where a substitution IS possible, and the
+precondition is asserted as a control BEFORE any behaviour.** TASK-203 round 4
+shipped a test on a clean board where no shrink was possible — the one test
+that could not tell — and its round 5 had to add an `assertLess` before its own
+control could fail. `stage_substitution` returns a `Staged` whose four control
+assertions run first, in `check()`, and one of them is `assertGreater`.

+"""`no store` and `store present but unusable` are different answers. TASK-095.
+
+**Written after the V4 round 1 review failed TASK-095 on exactly this.**
+
+`stored_tracks` returned a bare `None` for four different situations, and
+`declared_tracks` read the rendered `.perry/config.md § Tracks` in all four.
+One of those four is right; three are wrong:
+
+| situation | store on disk | reading the markdown is |
+|---|---|---|
+| no store | no | **correct** — the adoption path `P003-O2-KR1` excludes |
+| unreadable JSONL | **yes** | the condition the KR counts |
+| records do not validate | **yes** | the condition the KR counts |
+| no `kind: track` record | **yes** | the condition the KR counts |
+
+The reviewer reproduced it with a store holding valid `main` and `intake`
+records plus one truncated trailing line — the shape an interrupted write
+leaves. `intake` vanished from all four converted call sites at once:
+`perry-task --track intake` refused a track the project really declares,
+`perry-goals` reported it undeclared, `perry-diagnose` scanned one track, and
+`perry-state --json` carried **no signal at all** — the payload looked like an
+ordinary single-track project.
+
+**And every one of those branches was untested.** Three mutations inside the
+new code came back GREEN against `test_work_modes`, `test_md_store`,
+`test_store_drift` and `test_parsers`: `if findings:` → `if False:`,
+`return None` → `raise`, and `return None` → `return []`. No test called
+`stored_tracks` or `declared_tracks` directly. That is review finding 6, and it
+is why this module asserts the source of the answer and not only the answer.
+
+**The three callers do three different things, deliberately.**
+`perry-state` falls back and WARNS — it is the read-everything tool and must
+exit 0 on a project with no state at all, so it may not turn a corrupt store
+into a crash; what it may not do is stay silent. `perry-task` and `perry-goals`
+REFUSE on a write: they stamp `Track`, `Stage` and `Arrived` off this register
+and write `phase/`, and a row written against a register missing a track is not
+recoverable by re-running the command. `perry-task` still lets READS through,
+because refusing `list` would make a corrupt store un-diagnosable with the tool
+the user has in their hand.

+"""`tests/tree_guard.py` — and the plant that shows it can actually fail.
+
+A "the tree must not move" check is exactly the kind of guard that rots. It is
+green on every honest run, which is every run, so nothing ever exercises the
+branch that fails — and a guard whose failing branch is never taken is
+indistinguishable from a guard that has been broken for a year. This project
+has failed three rows in two days for shipping one.
+
+So the load-bearing test here is not the unit coverage of `manifest` and
+`compare` below it. It is `TestThePlantedWrite`, which copies this repository
+to a scratch directory, drops a test module into the copy that writes into the
+copy's own root, runs the **real** `bash tests/run` there, and requires that
+the suite comes back red naming the two paths that moved. Its mutation half
+neuters `tree_guard.compare` in a second copy and requires the same planted run
+to come back GREEN — because a red that would have been red anyway proves
+nothing about the guard.
+
+**Three things here exist because a V4 reviewer defeated the first version.**
+`test_all_three_ignore_lists_are_the_documented_ones` — the first version
+pinned two of the three lists, and blinding `IGNORE_NAMES` to `events.jsonl`
+and `intake.jsonl` left all thirteen tests green.
+`test_the_four_files_of_this_row_are_never_invisible` pins the same thing by
+consequence rather than by name, so a fourth list invented tomorrow is caught
+too. And `TestTheEnvironmentTheGuardCanSee` covers the vector the tree
+comparison structurally cannot see: `$PERRY_PROJECT` aimed at a second
+checkout, where all four files moved over there while step 0 truthfully
+reported this tree unmoved.
+
+The planting is into a COPY, never the live checkout: `work/reference/
+review-constraints.md` says so, and the reason is that for the seconds the
+plant exists, anything else running the suite sees a real, reproducible-looking
+failure about nothing.

+"""A declaration of drift is validated — at the writer and at the linter. TASK-227.
+
+`perry-goals link --unlinked <TASK-ID>` records that a KNOWN row serves no KR.
+It validated **nothing**, and `perry-lint` did not check `unlinked[]` either,
+so on 2026-08-28 two malformed declarations went into
+`phase/003-linkage.md` and the lint reported **0 errors** over both:
+
+1. the literal string `NOT-A-TASK-ID at all`, and
+2. **48 task ids space-joined into one argument.**
+
+The second is the one that matters. It is not a typo — it is the ordinary way
+this command gets called, from a loop, in a shell with word splitting off. The
+whole sweep landed as a single list entry while the command reported success 48
+times, and the repair was one hand edit back to `unlinked: []` followed by 48
+re-runs. That repair is recorded in `journal/2026-08/2026-08-28.md § OKR
+attribution sweep`; TASK-227 is the row it produced.
+
+**Two checks, deliberately different questions.**
+
+The writer asks about SHAPE: is this one handle, with no whitespace in it? A
+store lookup would not catch the joined case, because every id in that blob
+existed — whitespace is the only thing that tells 48 valid ids from one.
+
+The linter asks about the STORE: does a row with this id exist? It is `warn`,
+matching `linkage-task-exists` one key over, because a declaration about a row
+that was later purged is a stale record to correct, not a file to refuse. Doing
+it at the writer instead would make a declaration unwritable the day
+`perry-task purge` removes the row it names.
+
+Why an unchecked declaration is not free: `perry-state --section attribution`
+reports `declared_unlinked` straight off this list (TASK-228), so an id no row
+carries is a row the standup reports as *answered* — when no such row exists to
+have answered for.

+"""The tree the suite starts in must be the tree it ends in — byte for byte.
+
+## Why this exists (TASK-249)
+
+`bash tests/run` wrote Perry state into the repository it ran in. One test —
+`tests/test_task_writer.py § test_every_accepted_command_runs_and_is_advertised`
+— walked `PT.COMMANDS` and invoked `bin/perry-task <name>` with **no `--root`**.
+`perry-task` resolves its project root from `$PERRY_PROJECT`, else the cwd, and
+`tests/run` cds to the repository root, so 29 real commands ran against the live
+checkout. Twenty-eight of them refused for want of arguments. `intake-sweep`
+takes none: it discharged a real board row and moved four files —
+`.perry/events.jsonl`, `perry/BOARD.md`, `perry/intake.jsonl` and
+`perry/journal/<today>.md`.
+
+**It survived four months of green runs because the sweep is idempotent.** The
+natural check — run the suite twice and diff — reports nothing, because the
+first run leaves no discharged row for the second to find. Four agents
+confirmed it in twelve hours; none of them were looking for it, and the only
+reason it ever surfaced was that an append-only file conflicted at a merge. A
+fast-forward would have carried a stray `intake-sweep` event with actor `agent`
+into `main` in silence.
+
+## Why a guard rather than only a fixture
+
+The spec offered two shapes: a fixture that refuses a root inside the
+repository, or this. **A fixture guard could not have caught this one** — the
+offending call site does not go through any fixture. It builds its own `argv`
+and calls `subprocess.run` directly, which is exactly why it was the call site
+that got it wrong. A guard that compares the tree at both ends does not care
+how the write arrived: fixture, bare subprocess, a stray `open(..., "w")`, or a
+tool three layers down that resolved a root from the cwd.
+
+## The blind spot the project had already declared
+
+`tests/live_state_expectations.py § _tool_reads_this_project` decides which
+project a test's tool call reads from `--root`, then `cwd=`, then a state path
+among the arguments, and says of a call carrying none of the three: *"With none
+of them the answer is no — the tool would in fact inherit the runner's cwd and
+so read this repository, but `--help` and `--version` runs are the bulk of that
+population and **none of them touches state**. A stated blind spot, not a
+claim."*
+
+TASK-249's call site is exactly that shape, and `intake-sweep` is the
+counterexample to the sentence. The blind spot was declared honestly and the
+population turned out to have one member that wrote. That is the argument for a
+guard that watches the tree instead of reading the call: a static guard can only
+be as good as its statement about what the un-analysable population contains.
+
+## What it does NOT catch, said plainly
+
+Each of these was found by a reviewer or by looking for it. They are listed so
+that the next reader inherits the list rather than rediscovering it.
+
+- **An idempotent write on an already-written tree.** The very sweep that
+  motivated this file moves nothing on a tree it has already swept. The guard
+  catches the *first* occurrence — which is the one that matters, and the one
+  that would have been caught in the first place — not the steady state.
+- **A write to a DIFFERENT checkout.** The guard hashes `$ROOT` and only
+  `$ROOT`. A tool that resolves its root from `$PERRY_PROJECT` would write into
+  whatever tree that names while the guard reports `$ROOT` unmoved — and this
+  machine runs several worktrees, so it is not hypothetical. **`tests/run`
+  refuses to start** when `$PERRY_PROJECT` names any tree but `$ROOT`: it
+  prints both paths and the command that recovers, and exits 2 before step 1.
+  It does not silently re-aim the variable — see *Why a refusal and not a
+  re-aim*, below. Its comparison resolves both sides the way `perry-task`
+  does, so a symlink alias of `$ROOT`, or `$ROOT` with a trailing slash, is
+  this tree and is allowed through. What remains uncovered is a test that
+  builds its own `env=` dict naming a third directory; nothing a tree
+  comparison can do reaches that, and it is named here instead.
+- **`.git`.** A test that runs `git commit` in the live root gets through.
+  Hashing `.git` against a live repository would be slow and noisy — index and
+  ref mtimes move under any concurrent git command, including a reviewer's
+  `git log` in another terminal, and a guard that is red for reasons the reader
+  did not cause is a guard that gets switched off.
+- **`__pycache__` and `*.pyc` / `*.pyo`, at any depth.** Running the suite
+  compiles the suite. This is deliberate and unbounded on purpose: bytecode
+  legitimately appears beside any Python file.
+- **A file named `.DS_Store`, at any depth.** Written by the Finder, not by a
+  test, and it appears in whatever directory a human opened.
+- **EVERYTHING under a directory named `.claude` or `.gstack`, at any depth —
+  and the directory's own creation.** This is the widest hole on this list;
+  `.DS_Store` and `__pycache__` above are strictly narrower. Three separate
+  scopes, each measured with `compare()` returning `[]` while the control
+  writes beside them were reported normally:
+  1. *A directory that appears mid-run is invisible, and so is the fact that
+     it appeared.* `.claude/worktrees/agent-1/f` created between snapshot and
+     verify reports nothing — including no `+ .claude   (created)`, because
+     `os.walk`'s `dirnames` are filtered before the loop that records
+     directory entries.
+  2. *A write inside an ALREADY-EXISTING ignored directory is invisible too.*
+     With `.claude/` present at snapshot time it is not in the manifest at
+     all, so a test rewriting `.claude/settings.local.json` — the agent
+     harness's own permission allowlist — and creating `.claude/hooks.json`
+     produces an empty report. This is the scope that matters most and it is
+     the one the "a subagent worktree appears mid-run" story does not convey.
+  3. *The match is on the NAME, at any depth, not on the position.* A
+     directory called `.claude` or `.gstack` anywhere is skipped whole:
+     `perry/evidence/.claude/TASK-0NN-result.md` and `perry/.gstack/
+     tasks.jsonl` are as invisible as `./.claude/`. The same writes into
+     `.claudex/` are reported, so it is the name match and not the depth.
+  It is taken knowingly rather than by accident — the harness creates
+  `.claude` itself, from outside the run and in the middle of it, so ignoring
+  only `.claude/worktrees` would leave `+ .claude   (created)` red in a
+  worktree that had none (see *What is ignored*, below). Nothing is tracked
+  under either directory today; `git ls-files .claude .gstack` is empty, and
+  the day it is not, this is the bullet to re-read.
+- **A write that is reverted before the suite ends.** Two writes that cancel
+  are one tree.
+
+## Why a refusal and not a re-aim
+
+The other way to close the ambient case is to export `PERRY_PROJECT="$ROOT"`
+for the whole run, pinning every un-rooted write into the tree the guard
+watches. It was tried first and rejected, and the reason is a measurement, not
+a preference. Instrument, re-run on a `tar` copy of this branch on 2026-08-30:
+
+    env -u PERRY_PROJECT python3 -m unittest discover \
+        -s tests -p test_config_store_readers.py     ->  Ran 44 tests   OK
+    PERRY_PROJECT=<copy> python3 -m unittest discover \
+        -s tests -p test_config_store_readers.py     ->  FAILED (failures=7,
+                                                                 errors=2)
+
+**Nine tests**, which read the variable's ABSENCE as the signal to walk up
+from the cwd; the exported run also wrote `.perry/config.md` into the copy on
+its way past. A guard that has to bend nine tests to fit is a guard that will
+be bent back. Refusing costs nothing instead, because after the refusal the
+only two reachable states are "unset" and "resolves to `$ROOT`", and both land
+inside the tree step 0 hashes.
+
+## What is ignored, and the one rule that decides it
+
+The rule is: **this checkout actually produces it while a run is in flight,
+and no test may legitimately write it.** Both halves. Stating only one of them
+is how the earlier version of this paragraph came to contradict the `.git`
+bullet nine lines above it.
+
+- `.git`, `__pycache__`, `*.pyc` / `*.pyo`, `.DS_Store` — produced here,
+  constantly: a concurrent `git log` in another terminal, compiling the suite,
+  the Finder.
+- `.claude`, `.gstack` — produced here by the agent harness this project is
+  developed under, from OUTSIDE the suite and in the middle of it.
+  `.gitignore` describes `.claude/worktrees/` as "Subagent worktrees —
+  temporary, created by the Agent tool", and on this machine a subagent
+  starting during a five-minute run creates one. Nothing is tracked under
+  either directory. They are ignored whole rather than by inner path because
+  the harness creates `.claude` itself, so ignoring only `.claude/worktrees`
+  would still leave `+ .claude   (created)` red in a worktree that had none.
+- `.pytest_cache`, `.mypy_cache`, `.ruff_cache`, `node_modules` — NOT
+  produced here. They were carried in from habit; this repository has no tool
+  that makes one (`.github/workflows/ci.yml` installs nothing,
+  `.vscode/settings.json` sets `python.languageServer` to `None`). They fail
+  the first half of the rule and they are gone.
+
+One rule, three answers. The earlier text justified `.git` with "a guard that
+is red for reasons the reader did not cause is a guard that gets switched off"
+and justified the four deletions with "an entry that matches nothing is a
+blind spot held open for no benefit" — and a V4 reviewer was right that those
+two, stated that way, pull against each other: the second deletes `.git` the
+day `.git` stops churning, and the first re-adds `.ruff_cache` on the strength
+of a `ruff` nobody here runs. "Does this checkout produce it" is the question
+that separates them, and unlike either slogan it is answerable by looking.
+
+Every entry is a permanent hole, so all three lists are pinned by
+`tests/test_tree_guard.py`, and separately the four files of TASK-249 are
+asserted to be visible to the manifest — because pinning a list by equality
+catches a list that GREW and the thing to fear is a list that grew. That pin
+is also what makes `.claude` and `.gstack` a deliberate edit with a reason
+above it, rather than a red quietly made green.
+
+Usage:
+
+    python3 tests/tree_guard.py snapshot <root> <manifest-path>
+    python3 tests/tree_guard.py verify   <root> <manifest-path>
+
+`verify` exits 1 and names every path that moved. The manifest belongs OUTSIDE
+`<root>` — a manifest written into the tree it describes is itself a change to
+that tree.

 The criteria are written **by the author, before the round**. Criteria written
 after a FAIL are a negotiation with the result.
 
+### The criteria must be bounded
+
+A criterion is bounded when the author can name, **before the round**, the
+finite set the round will check and its size. "Every reader in `bin/` and
+`viewer/`" is not a set until someone says which readers those are and counts
+them.
+
+An unbounded criterion does not fail a round. It fails to **end** one.
+TASK-050 asked for a category:
+
+> "No reader resolves a header cell by its own rule. The check is a
+> **category** — an enumeration over the tree — not a list of file names."
+
+Proving that no reader *anywhere* does X is a search with no last element, and
+the rounds are that search:
+
+| round | what escaped the guard |
+|---|---|
+| 8 | the corpus was pruned — "30 of 30" was measured on a subset of itself |
+| 9 | a one-line alias |
+| 10 | a header row carried through a dict key |
+| 11 | **PASS** |
+
+Round 11 did not pass because round 10 named the last hole. It passed because
+round 10 **changed the criterion** — from *the set is empty* to *the remainder
+is measured and listed* — and the PASS says so in its own words:
+
+> "A measured, listed remainder of 8 out of 76 DOES discharge the amendment."
+
+**Eleven rounds ended on the round the criterion became decidable.** Ten of
+them were spent proving a universal negative over a live tree, by a reviewer
+who was right every single time. That is the shape to recognise: the rounds
+were not failing to find the answer, the question had no last answer.
+
+So the criteria file carries this block, and `perry-lint --reviews` reports its
+absence as `criteria-unbounded`:
+
+```
+## Bound
+Enumeration: grep -rn 'header_index(' bin/ viewer/   ← the command that produces the set
+Size:        58 call sites on 68e63cf
+Remainder:   readers reached only through `perry_store.load()`; out of scope
+             because they never see a raw header row
+```
+
+Three criterion shapes, and what to write instead:
+
+| written as | why it cannot end | write instead |
+|---|---|---|
+| "no X anywhere in the tree" | universal negative over a growing set | "these N sites, listed; the remainder is M, listed" |
+| "every X does Y" | "every" is not a set | the command that enumerates X, and the number it returns **today** |
+| "the guard cannot be evaded" | evasions are not a finite set | "these K evasion shapes, enumerated; a K+1th is a new row, not this round" |
+
+This does not soften § 2 rule 1. Rule 1 says enumerate the category rather than
+chase the next instance, and it is right — the failure it names is real and
+cost TASK-044 three rounds. **The bound is what makes rule 1 finishable.**
+Without it, "enumerate the category" and "prove a universal negative" are the
+same instruction, and TASK-050 is what that costs.
+
+A round may only widen the bound by **filing a new row**, never by re-opening
+this one. A remainder that turns out to matter is a defect with its own ID,
+its own criteria, and its own bound.

+### What V4 does not judge
+
+V4 answers one question: **does this code do the wrong thing on an input the
+user can produce?** Everything else the round can see is somebody else's job,
+and giving it to V4 is the second reason rounds do not converge.
+
+Measured on this board — 79 review documents, 54 `## Finding` headlines, 5 of
+them meta — **22 of the remaining 49 are about the round's own artifact rather
+than the product**:
+
+> "the harness is a regression corpus, not a harness" · "the corpus was pruned"
+> · "the reported baseline was incomplete" · "the commit record misreports a
+> mutation" · "three citations point at a file the branch does not carry" · "a
+> claimed filing, on the branch, that is not there" · "the code comment's
+> factual claim is false" · "the KR reframing must become an edit"
+
+Not one of those is a defect a user could hit. They are real — every one was
+correctly found — and they exist because the protocol **manufactures an
+artifact**, and the artifact has more failure modes than the code does. Round
+N+1 then audits round N's artifact, which is a loop with no product in it.
+
+So the line, and it is not "stop caring about test quality":
+
+| finding | rung | why |
+|---|---|---|
+| a mutation comes back **green** | **V4** | the guard does not work, or the test does not test it. § 2 rule 2. This is a product finding wearing a test's clothes. |
+| a guard reports **correct** code | **V4** | a false positive is a defect users switch the guard off over |
+| the cited path is not on the branch | **pre-check** | `perry-lint --reviews` → `citation-not-on-branch` |
+| the criteria carry no bound | **pre-check** | `criteria-unbounded` |
+| the baseline / corpus / mutation table is incomplete | **the author, before dispatch** | it is the author's exhibit; an incomplete exhibit is not sent |
+| a comment, a KR or a commit message misstates something | **file a row** | a documentation defect with its own ID, never a FAIL on this one |
+
+**The pre-check runs before the round is dispatched, not inside it.**

+```
+
+A round dispatched over a red pre-check pays a full fresh-context review to
+learn something a regex knew. That is the most expensive way this board has
+found to discover a broken citation, and it found it four times.
+
+**A FAIL must name a behaviour.** `proof:` points at the line that is wrong and
+`checked:` names the input that reaches it. A FAIL whose proof is "the evidence
+does not establish this" is not a FAIL — it is the pre-check, arriving late and
+costing a round.

 `review` means *a result is out for verification*. A row whose verdict has

+
+## 6 · Two FAILs is a decision, not a third round
+
+**After the second FAIL on a row — two being the default limit, see the end of
+this section — you may not dispatch another round.** File the ask instead.
+`perry-lint --reviews` reports the row as `review-rounds-exhausted` until an
+open ask in `asks.jsonl` names it in `blocks`.
+
+This is the most expensive rule on the page and it was bought with the whole
+board. Measured on Perry's own state: **20 rows entered V4 and 74 rounds were
+burned.** Ten rows needed three or more. TASK-050 and TASK-249 each reached
+**round 11**. TASK-095 FAILed five times, and the escalation that ended it —
+USER-905 — was filed by hand at round 5, after which the user picked a
+principle and round 6 PASSed on the first try.
+
+Read the five TASK-095 FAILs in the journal and they are one sentence:
+
+> Every one is the same shape: two situations answered as one, one step to
+> the left of the last.
+
+Rounds 3, 4 and 5 were not finding new defects. They were re-deriving one
+undecided principle differently each time — and each round costs a dispatch, a
+fresh-context review and a fix cycle, with the session paying its entire
+context on every turn of all three. **Rounds after the second are the most
+expensive thing Perry does and the least likely to converge.**
+
+The second FAIL is the signal, and it is legible at the second FAIL. Rule 1
+says enumerate the category rather than find the next instance; **two FAILs
+means the category is not a category — it is a fork nobody has taken.** The
+deliverable is no longer a fix, it is the choice:
+
+```
+"$PERRY_HOME/bin/perry-task" ask --needed "<A vs B, and which you recommend>" \
+                                 --blocks <TASK-ID>
+```
+
+Write it the way USER-905 was written, because that is the one that worked:
+state the two readings so each is defensible **applied consistently**, show
+that the current code holds both, name your recommendation with its reason,
+and say what is already true (which tool computes the rule today, what is
+merged, what is not). The user picks a principle; the next round applies it
+everywhere and PASSes.
+
+**Two is a measured default, not a law.** It is
+`schema § thresholds.review_fail_rounds_before_escalation`; a project sets its
+own with `- Review rounds before escalation: N` in `.perry/config.md`, and a
+single run overrides both with `PERRY_REVIEW_ROUNDS=N`. The finding names
+which of the three set the limit it is enforcing. Raise it for work that
+genuinely converges by accretion; `1` makes every FAIL a decision point.
+
+A `review-rounds-exhausted` finding is never cleared by running the round
+anyway.
