train 17: pinned bench populations, --readability ordering claim withdrawn, re-scorable ack provenance - #329

Conversation
Swept bench/, docs/, scripts/ and test/lib/ for measurement scripts that walk git history without pinning the population they count over — the defect class that forced the retraction of bench/readability_refactor_pairs.py's "484 matched pairs, 30.2%" in docs/EVALS.md (that fix lives on an unmerged lane and isn't in this tree; nothing here restates its numbers). Found two live, unfixed instances of the same class: - bench/shotgun/README.md's recipe ran a bare `git log` with no ref, so the 2026-09-08 "this repository: 1,731 files, 15,220 symbols, 1,587 non-merge commits" figures in docs/EVALS.md's Shotgun Surgery section carry no recorded population and cannot be reproduced against a named commit. Flagged loudly in the README rather than silently restated; the recipe now takes REF (default v0.6.2) and builds the map from a worktree checked out at the same ref the log was walked from. - bench/slice/run_slicerecall.py mined `git log` from bare HEAD of `--repo` (default "."), which docs/EVALS.md's own "corpus problem, settled" note already worked around by hand (always mining from a throwaway checkout DETACHED at a stated pin). The harness now takes --ref (default v0.6.2, this tree's own tag) and records the resolved ref+sha in its summary output, turning that operator discipline into the harness's own default. The b156027 numbers already recorded in EVALS.md are untouched — they were pinned by hand, same mechanism. Everything else the sweep found either already pins by ref+assert (bench/roundc-h2h/derive_questions.py), pins by content-hash lock (bench/cppbench/run_cppbench.py's dataset.lock), records its own sha per row (bench/ensemblecal/run_ensemblecal.py, bench/capsweep/ capsweep.py), or is a local-only opt-in tool that never publishes a number (bench/mine_traces.py's --only-committed). Gated: test/ripwirepubliccheck.sh arm 9 sweeps bench/, docs/, scripts/ and test/lib/ for a `git log`/`rev-list`/`for-each-ref` invocation carrying no ref-shaped token (or any `--all`/`--branches`/`--remotes`), with an allowlist keyed to exact (path, line) pairs for the legitimate cases above. Proved red-first against the pre-fix content of both files (reverted, gate run, restored); the two fixes are what turns it green. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
…self The prior commit's caveat about the unpinned 2026-09-08 Shotgun Surgery figures lived only in bench/shotgun/README.md; a reader meets the numbers in docs/EVALS.md, so that is where the disclosure has to live too. Ran the now-pinned bench/shotgun/ recipe at REF=v0.6.2 (15a2085, 2026-09-22) against this repository. It is a genuinely later, larger population (v0.6.2 postdates the 2026-09-08 run by two weeks of landed work: 2,171 files / 21,619 symbols / 2,930 non-merge commits vs. 1,731 / 15,220 / 1,587), not a reproduction of the old figures, so every "this repository" row across (a)-(c) and the two follow-on paragraphs now carries both numbers: the pinned one as current, and the 2026-09-08 one inline as "first recorded as ... (unpinned — does not reproduce)" — never silently replaced, never deleted. The private ObjC++/C++ game-tree corpus rows are marked RETRACTED rather than replaced: that corpus is a private, unpushed local checkout with no ref or sha ever recorded against the 2026-09-08 run, outside anything this tree's own gates can verify, and it is not something this session can safely re-measure or pin. Its numbers stay as the historical record only. One more implicated aside turned up while in there (the CM×CC "crediting every .size() flags 263/2,655 empty/find/size-named symbols" resolver- artifact illustration) — noted as measured on the 2026-09-08 corpus and not re-derived this round, rather than guessed at: my attempt to reconstruct the same computation on the pinned map did not clearly match the original's methodology, and the point it illustrates does not depend on the exact count.

Each ack row now carries optional now=/was=/facet=/p=<path>:<line> tokens alongside the existing cid=/by= ones, so a later run can re-evaluate a finding's materiality under a different bar/minorDelta threshold (the planned knob sweep) by reading the ledger alone, with no re-ingest and no git history replay. was/now are the exact pair perSymbolKind compares against a kind's bar (now factored into the shared numericRegressionIsMajor so the live report and rescoreNumericMajor can never silently disagree); facet carries the idiom/churn/surface classification for the kinds whose severity isn't a bar comparison at all. The hash stays the sole match key; these are additive, honest provenance only. Legacy rows (nothing this binary wrote/refreshed) are read as hasProvenance=false and never treated as re-scorable — 0 (a legitimate measured value) is indistinguishable from an absent token, so presence, not value, is the tell. They heal FORWARD on their next --quality-ack, same posture as R1 cid= and P1.4 by=. The ledger's own header and AckRecord's doc comment now say plainly that a legacy row cannot be backfilled from this file alone (no row anchors a commit), and a follow-up has been flagged to add that anchor / run a one-time git-archaeology backfill so the sweep can also reach pre-existing acks. A write-path ENSURES (verbs_quality.h) re-scores every row --quality-ack just wrote and aborts if it disagrees with the just-computed live verdict — the "round trip reproduces the same verdict" proof, exercised on every real ack rather than a one-off test. test/qackconcurrencycheck.sh gains arm 8 (extending the existing qack gate family rather than a new gate file): a magnitude-bearing ack row must carry now=/was= and, for a recognized clone idiom, facet=; proven red against the pre-provenance binary. Its pinned grammar regex is updated to accept the new optional tokens, and the committed ledger's header comment is kept byte-identical to what the binary itself now writes (H10).

--quality-delta caught its own new code: the new numeric-token parser (takeAckUintPrefix) duplicated takeAckCidPrefix's shape, and a one-line materialityBarFor wrapper around the new kind-lookup helper turned out to be short enough to clone-match three unrelated one-line forwarders elsewhere in the tree. Both are now genuinely shared: takeAckCidPrefix and takeAckUintPrefix delegate to one takeAckNumericToken (cid= keeps its existing DISCLOSE on a malformed value via a malformed-out-param; the new now=/was= tokens stay silent by design, no new one-argument DISCLOSE), and the trivial materialityBarFor wrapper is gone — its one caller (rescoreNumericMajor) calls findRowByKind directly, the same helper facetAttrName now also shares. Also fixes the ENSURES round-trip self-check added in the prior commit: its promise called optional::has_value()/operator*, which test/selfcheckcheck.sh's promise-accessor rule (arm C) refuses on new code; the boolean is now computed in a plain local before the ENSURES call so the promise itself is a bare identifier. ./build/ripwire . --quality-delta now reports gating="0" on this branch's own diff vs origin/main (3 short-horizon-churn minor rows only, expected churn on freshly-edited code).

Independent review of this lane found two defects in what it just shipped: - test/ripwirepubliccheck.sh arm 9's PIN_SIGNAL check ran against the whole line, so `git for-each-ref`'s own command name (containing a `\bref\b`- shaped substring) satisfied the "this line names a fixed point" heuristic by itself — the exact `for-each-ref ... | git log` shape the arm's header comment lists as a target silently passed. Mask the matched git-invocation text out of the line before testing PIN_SIGNAL/ALL_TOKEN, so the verb's own spelling can no longer prove its own pin. A for-each-ref call pinned to a real ref (e.g. `refs/tags/v0.6.2`) still reads clean. - bench/shotgun/cc_vs_history.py built its per-file `rows` list by iterating a Python `set` (`indexed`), whose order is hash-seed-randomized. The CC_file=0 tie-break in the quintile split then depended on that seed: three fresh runs of the SAME pinned map/history reproduced rho and n exactly but printed three different Q1-Q5 scatter tables. Iterate `sorted(indexed)` instead; verified deterministic across repeated fresh-seed re-runs. docs/EVALS.md's pinned quintile row is updated to the now-reproducible figures, with a note on why the old ones moved. Re-ran every other pinned-recipe figure in this lane's docs/EVALS.md rewrite (cc_static.py, cochange_backtest.py, cochange_followup.py) against REF=v0.6.2 and all of it reproduces exactly.

Follow-up to 1bd8b7c. The (path, line-number) allowlist key was itself a false-alarm channel: an edit ANYWHERE above an exempted line shifts every subsequent line number, so an unrelated, unreviewed change elsewhere in the file drops an already-vetted hit off its key and arm 9 re-reports it as new — demonstrated live by inserting one blank line above bench/mine_traces.py's two exemptions (242, 361 -> 243, 362), neither of which was itself touched. Re-key each entry as (path, sha256[:16] of the exact matched line's text). This survives the line-shift case (proved: the same blank-line insertion no longer reports anything) and still re-fires the moment the matched line's OWN content changes (proved: swapping --name-only for --stat on the line-242 exemption in bench/mine_traces.py correctly re-triggers arm 9, restored after). The per-entry human-readable reasons are unchanged; the line numbers in the comment are now explicitly commentary, not the key. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
…dability docs/research/readability-construct-validity.md §4 (a1b1930) tested whether --readability's ordering predicts later fixes, holding size roughly constant. Stratified into ten narrow token-count deciles, the association disappears in 8 of 10 (CIs include 1); the two that stay significant are the two deciles with the most leftover internal token-range spread. The raw/tercile separation reads as a residual size effect in the lens's own units, not an independent readability signal — the same mechanism §3c already found driving the lens's direction on refactor pairs. - Reword --readability's one-line --help summary to state the mechanism (orders by Halstead volume/token entropy/length) without claiming a readability ordering. - Extend the MEASURED paragraph with the withdrawal and its evidence, pointing at docs/EVALS.md §8 for the derivation. - Mirror both in README.md's lens table and its `--readability` writeup. - Record the withdrawal in docs/EVALS.md §8 alongside the figures it supersedes, keeping every earlier number visible as history. - Regenerate docs/COMMANDS.md from the binary and re-pin test/printf_parity.manifest (UPDATE_GOLDEN=1): `help` and `help_all` both move, since the reworded one-line summary appears in both the budgeted first screen and the full catalog; all other 40 verbs are unchanged.

… trip it never performs rescoreAckRecord runs on the in-memory AckRecord right after --quality-ack builds it, never through renderAckRecords/readAckRecords — so it proves the table-driven re-score formula (rescoreNumericMajor via kMaterialityBars) agrees with the live one (numericRegressionIsMajor via perSymbolKind's call-site literals), not that the ledger's text grammar round-trips. The comments in verbs_quality.h and qackconcurrencycheck.sh both called it a "round trip... reading the row it just wrote back exactly as readAckRecords would", which overstates what the check covers and could lead a future reader to skip writing a real serialize+reparse test for takeAckProvenance/splitAckLocator. Independently verified that path IS correct today (a standalone harness round-tripped permuted token order, was=0 vs absent, colon-bearing paths, malformed line suffixes, unknown future tokens, and the P0.3 kind-suffix strip — all honest), but nothing in the tree currently asserts it, so the comments now say so precisely instead of implying the ENSURES already does. No functional change: ENSURES still gates on the same rescoreAgrees condition. Full gate suite clean (gates=662 pass=659 skip=3 fail=0), quality-delta=b939ef4f..HEAD gating=0, determinism and xmllint hold. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
The provenance the prior commits added reaches only rows --quality-ack
WRITES, so this repo's own 1,623-row ledger carried none and the knob
sweep could re-score none of its own history. The obvious follow-up — a
commit anchor plus a git-archaeology pass to recover `was=` — turns out
to be aimed at the wrong rows, and measuring first is what showed it.
Of the 1,623 rows only 320 are numeric-bar rows, the only class
rescoreNumericMajor answers for at all. The 288 CLONE rows (62 of them
the reuse-decline kind the sweep specifically wants) have no
kMaterialityBars row, so rescoreNumericMajor's lookup misses and NO
recovered was= could change their verdict — their severity is `facet`.
A commit anchor would have resolved 0 of those 62, by construction
rather than by heuristic failure.
They need no git at all. Their ack identity IS cloneGroupHash (the
sorted member canonIds), classifyCloneGroupIdioms runs over every clone
group in the current tree regardless of newness, and `was` is 0 by
construction at both kinds' push_back sites — so today's tree answers
all three fields. Measured on the real ledger: 231 of 288 clone rows
reconstructed, including 47 of the 62 (3 carrying a named idiom, 44
reconstructing to CloneIdiom::None, which is the verdict that leaves the
finding at full severity rather than an absent answer). The 57 it cannot
reach are a floor, not a claim the groups are gone.
AckRecord::hasProvenance becomes a tri-state AckProvenance
{None, Measured, Reconstructed}; hasProvenance() stays as a derived
predicate so no existing call site changed meaning. `prov=recon` is
omitted for Measured — the same OMIT-when-default rule cid=/by= follow —
so a ledger of live-written rows is byte-identical to one written
without the axis, and qackconcurrencycheck arm 7's round trip over the
real ledger moves no byte until a backfill actually runs. A
reconstruction is a CACHE, not a dated record: every --quality-ack
re-derives the rows whose group it can still find. One it CANNOT find is
left intact and counted UNVERIFIED, never cleared — an earlier draft
withdrew those, and arm 7's transplant probe caught it deleting all 231
rows when the ledger was read beside a different tree. `facts` is what
the run FOUND; scoping, a size cap or a degraded parse all produce a
miss, and deleting derived data on the strength of a floor is the guess
the honesty contract forbids, made irreversibly.
The backfill runs BEFORE the live fold, so a measurement overwrites a
reconstruction by ordering rather than by a check. Clone facts ride a
defaulted cloneIdiomsOut out-param on computeDelta, taken before either
reporting lambda so the newness/test-script/fan-in filters cannot hide
the rows the pass exists to reach — no second clone pass. Re-scoring
goes only through rescoreAckRecord; there is no second copy of the
materiality rule. AckBackfill carries a `measured` count so the stderr
disclosure sums to the ledger: a report whose claim is that its floors
are honest must not print counts that visibly do not add up.
The numeric rows stay honestly unreachable and AckRecord's doc comment
now says so per kind, with the measured cost of the separate lane that
could reach them (320 rows blame to 86 distinct commits at b939ef4,
~13 min) and why the LAST write, not the first appearance, is the commit
to re-diff: the `was` must match the row's current ackNow. A re-measured
was is MEASURED and must not reuse prov=recon.
qackconcurrencycheck arm 9 (extending the qack family, no new gate
file): reconstruction, disclosure, idempotence, measured-beats-
reconstructed, the honest refusal to invent a numeric row's was=, and
the non-deletion of an unverifiable row. Arm 9f covers the class the
write-path ENSURES does NOT — that promise re-scores an in-memory record
and never touches renderAckRecords/readAckRecords, so serialisation and
parsing are invisible to it, which is exactly where prov=, the tri-state
and the omit rule live. A hand-written fixture ledger carries the shapes
the binary never emits (permuted token order, an unknown prov= value, a
half pair, a ':' inside p=) and is read and rewritten by the shipping
binary, including proving from the bytes that no row carries both a
measurement and a reconstruction. Proven RED against the pre-backfill
binary: 7 of arm 9's assertions fail there.
Full suite clean (gates=662 pass=659 skip=3 fail=0, tree_writes=0),
--quality-delta vs c0cc08b gating=0, determinism and xmllint hold.

lane/bench-pin-populations (5fea9f1) added a --ref flag to bench/slice/run_slicerecall.py and quotes it twice in docs/EVALS.md's --slice-guards corpus note. deckcheck scans that prose and, finding no --ref in `ripwire --help=all`, reported both lines as fabricated flags. It is red at the lane tip itself; deckcheck was not in the lane's gate list, and the train's doc gates caught it. --ref belongs to the harness, not to ripwire, so it takes an allowlist row next to the same harness's --repo and --cap rows, with its reason.

…ssing row Arm 9f's half-pair check (row 4444..., now= with no was=) is a negative test: it greps the rewritten row for a provenance token run and passes when nothing matches. It piped rt_row into grep -q, so a rewrite that dropped the row entirely left grep nothing to match and the arm printed PASS. Its four sibling sub-arms already fail on a missing row through their case fall-through; this one did not. The row is now read once and required to be present before its lack of provenance counts. Red-first by mutation (the row deleted from the rewritten fixture ledger): the previous gate rc=0 with this arm PASS, this gate rc=1 with it FAIL. Unmutated: rc=0, 31 PASS. Found by the train 17 pre-PR review checklist (pipeline whose failure is swallowed). Gate logic only; no ledger bytes or output change. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
…sh-eyes lane/readability-withdraw-ordering (47725a7) withdrew --readability's ordering claim in the help, README, COMMANDS and EVALS section 8, but skills/ripwire-fresh-eyes/SKILL.md still told agents the row order "ranks by how hard the text is to read" and to "read the ORDER of the rows". That is the claim that was withdrawn, restated one file over, and it is the surface an agent actually follows. The paragraph now describes the order the way the help does (Halstead volume, token entropy and length, largest first), keeps both earlier caveats, and adds the withdrawal with its figure (8 of 10 token-count deciles, so a size proxy) and a pointer to docs/EVALS.md section 8. Found by the train 17 pre-PR review checklist (a changed claim grepped across README/docs/skills). skilltruthcheck, skilldescbudgetcheck, skillinstallcheck, skillscanreadcheck, deckcheck, readmedriftcheck, docanchorcheck, docdriftcheck and textdocscheck pass.

Inline comments:
In `@bench/shotgun/README.md`:
- Line 18: Resolve the selected REF or --ref to a commit SHA once, then use that
SHA for the history walk, recorded reference, detached worktree, and candidate
mining so every measurement uses the same immutable revision. Keep the original
ref only for descriptive output.
In `@docs/COMMANDS.md`:
- Line 1840: Remove the stale “LEAST readable first” wording and align the
descriptions with the largest-first ordering. In docs/COMMANDS.md:1840-1840,
update the ordering description; also update its example heading at Line 1846
and output comment at Line 1850. In src/cli.h:1381-1381, update the stale label
and its example output comment at Line 1850 to match the current largest-first
behavior.
In `@docs/EVALS.md`:
- Around line 8632-8634: Update the historical rerun instructions for the
recorded 7-commit, 38-instance measurement to explicitly pass --ref=b156027;
checking out b156027 alone no longer selects the intended mining population
because the harness defaults to v0.6.2.
In `@src/quality.h`:
- Around line 6395-6430: Update ackProvenanceTokens to emit facet= and p= only
when their values are nonempty and scopeSpecIsSpellable, omitting unspellable
values so whitespace or newlines cannot corrupt the ledger’s token or record
boundaries.
- Around line 6098-6107: Update takeAckUintPrefix to reject values above
UINT32_MAX and tokens without a leading digit, restoring the original reason on
rejection so malformed input remains visible; only narrow validated values.
Apply the same range and leading-digit validation in splitAckLocator, using a
fixed-width parse so oversized line numbers consistently fall back to the whole
token across platforms.
In `@src/verbs_quality.h`:
- Around line 1236-1242: Update the unresolved-count wording in the stderr
message emitted by the backfill reporting block to describe
`backfilled.unresolved` as a floor because the group was not found, without
claiming the member set does not clone here.
In `@test/qackconcurrencycheck.sh`:
- Around line 547-554: Update the case statement checking NUMROW in the re-ack
test so an empty value fails instead of passing as an honest refusal. Preserve
the existing failure for rows containing prov= and the pass for present rows
without reconstructed provenance.
- Around line 403-407: Remove the `prov=recon`-only PASS case from the `BFROW`
check in arm 9 of `test/qackconcurrencycheck.sh`; require
`facet=threshold-ladder` for a reconstructed row to pass, and report failure
with the row when `prov=recon` is present without that facet.
In `@test/ripwirepubliccheck.sh`:
- Line 1295: Update the `PIN_SIGNAL` regex to remove global case-insensitive
matching so lowercase `head` and ordinary `Ref` or `pin` text do not count as
pins; explicitly allow intended case variants only where needed, while keeping
`HEAD` and tag shapes case-sensitive.
- Line 1287: In the arm 9 scanner, check the Python heredoc’s exit status before
treating empty output as success, and report a nonzero exit as a failed
history-walk sweep. In the tracked-file scan, report an unreadable in-scope file
instead of silently skipping it.

lane/readability-withdraw-ordering (47725a7) withdrew the claim that --readability's order is a readability order: held to narrow token-count bands, the later-fix association disappears in 8 of 10 deciles, so the order is a size proxy (docs/EVALS.md section 8). It changed the one-line help summary, but the same help entry, and the legends the verb emits, still called the order "least readable first": - src/cli.h --help=all body: now "LARGEST Halstead volume/token-count/ length first (a size proxy, not a readability order)", the wording the --biggest-first lane already uses, so the two merge without a new disagreement. - src/readability.h full legend: the order is P ascending, which puts the largest volume, token count and length first, stated as a size proxy with the withdrawal. "the least-readable extreme" of the sigmoid becomes "its low end". - src/compactlegend.h compact legend (the default): "largest Halstead volume first (a size proxy)". - src/ensemble.h / src/qualitypanel.h: rank 0 is "the lowest posnett=, the largest body", not "least readable". - Comments in cli.h, readability.h and verbs_quality.h say the same. Prose only: the <readability> root, the schema, every attribute and the legend keys are unchanged. Pins moved, re-anchored here with the reason recorded: - compactlegendcheck: ripwire.readability/v1 320 -> 350 (measured 332; +24 B), per the table's measured+10 rule. - printf_parity.manifest: help_all only (UPDATE_GOLDEN_EXPECT=help_all). - docs/captures/COMMANDS_showcase_2026-09-14.md, corrected in place: the --readability sample's legend line is the new binary's; its caption matches the recorder (test/showcase_capture.py). The --quality-panel and --ensemble totals move +19 B and +42 B (18135 -> 18154, 10936 -> 10978). --legend-dict: dictv=2d9cec7852fd809b -> 7c89394f1b3da99d, 68632 -> 68656 B, 704 entries. - docs/COMMANDS.md regenerated from the binary. readabilitycheck (G) follows the new saturation wording. New arm (G2) fails if either legend still says "least readable first" or stops calling the order a size proxy. It reads both legends into variables first, so an empty run fails too. Red on a 0d6f049 binary ((G) and (G2) FAIL, rc=1), green here. Found by the independent train review (F1); CodeRabbit named the same text on docs/COMMANDS.md and src/cli.h.

… defect Arm 9 of test/qackconcurrencycheck.sh had two sub-arms that printed PASS on exactly the defect they exist to catch: - The reconstruction check accepted a row carrying prov=recon with no facet= as "the idiom verdict is None here". The fixture is a copy of arm 8's tree, and arm 8 asserts facet=threshold-ladder on it, so None is not a valid answer: that branch could only hide a reconstruction that lost the idiom. It now fails. - The legacy-numeric-row check is a negative test (no prov= on the row). A re-ack that deleted the row left NUMROW empty, and the fall-through printed "the honest refusal". An empty row now fails, as arm 9f's half-pair check already does. Red-first by mutation, on the same binary: - facet= stripped from the reconstructed row: the previous sub-arm PASS, this one FAIL. - the complexity row deleted before NUMROW is read: previous gate rc=0 with that sub-arm PASS, this gate rc=1 with it FAIL. Unmutated: rc=0. Raised by CodeRabbit on PR #329 (test/qackconcurrencycheck.sh 403-407 and 547-554); both verified before the change. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
…readable locator The ack ledger is committed and hand-edited, so its tokens are external input. Two ways a row came back different from what it said: - Integers. takeAckUintPrefix narrowed strtoull's result to 32 bits, and splitAckLocator used strtoul. strtoull accepts a leading '-' and negates, and unsigned long is 64 bits on LP64 but 32 on Windows. On this machine a hand-written now=4294967296 read back as now=0, now=-1 as now=4294967295, and the same happened to a p= line number. Both now go through parseAckLedgerUint32, which takes 1-10 ASCII digits that fit 32 bits and nothing else, checked with VALIDATE in the refusing condition. A value it rejects keeps the existing degrade: now=/was= stay visible in the reason, and a p= token stays whole as the path. No value is fabricated. - Locators. ackProvenanceTokens wrote p= and facet= verbatim into a whitespace-delimited line. A finding on "my dir/a b.py" was written as p=my dir/a b.py:1 and read back as path "my", line 0, with the rest pushed into the reason, and the next ack committed that. A value that cannot be spelled as one token is now omitted, under the same closed set by= already uses (scopeSpecIsSpellable). An absent locator is the honest degrade; nothing decides anything from p=. Rows this binary already writes are unchanged: arms 6 and 7 still read the committed ledger back byte-identically. qackconcurrencycheck arm 10 pins both halves. (10a) four hand-written out-of-range or negative values stay visible. (10b) a live finding on a path with a space keeps now=/was= and its reason and round-trips through a second ack. Red on a 0d6f049 binary (all five checks FAIL, rc=1), green here (rc=0, 37 PASS). Raised by CodeRabbit on PR #329 (src/quality.h 6098-6134 and 6395-6430); both reproduced through the binary before the change. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
…n a piped head
Two ways arm 9 (unpinned git-history walks in measurement scripts)
reported a clean sweep it had not made:
- The scanner's exit status was never read. A python exception left
$TMP/arm9 empty and the arm printed PASS. The status is now checked,
and a nonzero exit fails the arm. A tracked in-scope file that cannot
be opened is now reported instead of silently skipped.
- PIN_SIGNAL was compiled with re.IGNORECASE, so the \bHEAD\b meant for
a pinned HEAD also matched the `| head -n 50` a recipe pipes into, and
`git log --format=%H | head -n 50` read as pinned. The pattern is now
case-sensitive and lists each accepted spelling (HEAD, --ref, ref/REF,
PIN, a hex sha in either case, a vN.N tag). No tracked hit moved: arm
9 is green on this tree.
Red-first by mutation, same binary:
- scanner pointed at a missing input: previous arm PASS, this arm FAIL
("the history-walk scanner exited 1").
- an unpinned `git log --format=%H | head -n 50` added to a tracked
bench script: previous gate rc=0 with arm 9 PASS, this gate rc=1
naming the line.
Raised by CodeRabbit on PR #329 (test/ripwirepubliccheck.sh 1287 and
1295); both verified before the change.

bench/shotgun/README.md resolved REF three times (the walk, the record, the checkout), and run_slicerecall.py recorded ref_sha but mined by the ref's name. With the default v0.6.2 tag these agree. With a caller's moving branch, the population walked could differ from the sha recorded. Both now resolve once: - the shotgun recipe keeps the given name in REF_NAME for its message and walks, records and checks out the resolved sha; - the slice harness mines ref_sha. The git log lines themselves are byte-identical, so ripwirepubliccheck arm 9's content-keyed allowlist is untouched. Checked: at v0.6.2 the slice mine returns the same 41 candidates by name and by sha, and the shotgun walk returns the same 2,930 non-merge commits EVALS.md records.

…f=b156027 The --slice-guards registration freezes its corpus by checking out b156027. Since lane/bench-pin-populations, run_slicerecall.py walks --ref, default v0.6.2, whatever the checkout. So that checkout alone now mines a later, different population. The note now says to pass --ref=b156027 as well. The recorded 7-commit / 38-instance figures are unchanged.

Merges four signed lanes, in order:
bench/shotgun takes REF, so both history walks start from a fixed point. cc_vs_history.py's
quintile table no longer depends on hash order. ripwirepubliccheck arm 9 flags any unpinned
history walk in a measurement script. EVALS.md publishes the pinned Shotgun Surgery re-run and
keeps the earlier figures, labelled as unpinned or retracted.
and EVALS section 8 withdraw the claim that its order predicts later fixes. The longer help body still
says "LEAST readable first"; that wording is corrected in the pending --biggest-first rename lane. Held to narrow token-count
bands, the association disappears in 8 of 10 deciles, so the order is a size proxy.
now=/was=/facet=/p=, so a later run can re-score them; an ENSURES re-score self-check was added.
the current tree (prov=recon) and leaves 57 legacy rows byte-identical.
Fixes made while building the train:
(red-first by mutation).
No merge conflicts. Generated docs re-derived from the merged binary; none changed. Local suite:
647/662 pass, 0 regressions. The sanitizer-built gates cannot run on the local machine, so CI's
asan job is their proof. quality-delta against main: gating=0.
