train 16: honest --readability help, reuse-decline idiom disclosure, --slice def-use order - #322
Conversation
…e root states slicecheck (order): mix:x must emit 4,2,5 (def-use coverage desc, then line) with order="defuse" on the root, defined in both legend tiers and --help, and a flow run must keep the seed rows in that order. Red on origin/main 15a2085 (all six assertions): rows come out 2,4,5 in source order, unstated. PRE-REGISTERED (2026-09-22, written before any src/ change and before any number below was computed): Rule under test: R1 def-use coverage. A --slice=SYM:VAR row's score is the number of distinct sliceable locals with an occurrence on that line; rows emit score-descending, then line ascending, then binding line ascending (file is constant: one definition). Zero fitted parameters. Measurement: bench/slice/run_slice_linerecall.py from lane/research-arise-slice (LocBench V1 test, py single-function rows), plus one scratch arm that reads the EMITTED order: per (scored instance, inventory variable) whose v1 rows hold a gold line, Recall@{1,3,5,10,20} and MRR of the l= values in emission order against gold & rows, versus a uniform random permutation of the same rows (200 shuffles, seed 20260920, own RNG). Population: every inventory variable (unseeded); the gold-touched subset is reported beside it, never instead of it. Decision: ADOPT R1 ordering iff the new binary's emitted-order MRR beats the random control's MRR on the all-inventory population. Otherwise stop ranking: emit in source order, and state that order in the header as a presentation order, not a ranking. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
…ot says so (order="defuse") The seed rows came out in source order with nothing on the root naming it. Measured on the lane/research-arise-slice harness (LocBench V1 test, py single-function rows, 173 scored instances, 478 instance x variable pairs holding a gold line), source order pinpoints a gold line WORSE than a uniform shuffle of the same rows: MRR 0.525 vs 0.602, @1 0.198 vs 0.268. Rows now emit by def-use coverage (distinct sliceable-local NAMES with an occurrence on the line — unbound identifiers such as a called builtin do not count), descending, then line, then binding line, then fold index: a total order, zero fitted parameters. Emitted order after: MRR 0.628, @1 0.285, @3 0.743, @5 0.847 (random 0.602 / 0.268 / 0.676 / 0.827); @10/@20 tie the shuffle (0.937 vs 0.939, 0.983 vs 0.983). The pre-registered rule (first commit of this lane: adopt iff emitted-order MRR beats the random control) is met. In-sample, legitimately: nothing was fitted. The emitted order equals the harness's own R1 over the same rows on 478/478 pairs. The root carries order="defuse" in VAR mode (flow runs too: the seed rows keep this order, the flow rows keep their stated (d=, l=, v=) order); the full legend, the compact slice legend, the default compact layer's slice readings and --help define it. The inventory (<v>) order is unchanged. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
… what the new reading moved - The full legend's order="defuse" clause is cut to one line: sliceflowcheck (30b) holds the v1 legend to 4,608 B and the longer clause took it to 4,808 B. - sliceflowsenscheck's sentinel re-derives the SOURCE-order reaching rule from the tool's own rows; it walked them in emission order, which is no longer line order. It now sorts by line first. Every rd= value is still checked row by row, unchanged. - The new compact reading adds one dictionary entry: the showcase capture's recorded --legend-dict figure is corrected in place (dictv=fd7a59c7c536eb85 entries=704, 68,575 B on 705 lines), and docs/COMMANDS.md is regenerated from it and from the new --help. - printf_parity.manifest re-pins help_all: the --slice help entry moved on purpose.

…v0.6.2 figures --readability's --help text, README.md and docs/COMMANDS.md quoted "484 matched pairs ... 30.2%" for the construct-validity proxy. That number came from an unpinned `git log --all` walk over a clone whose branch set changes every time a lane is pushed, and does not reproduce (413/38.3% and 409/38.4% on reruns that touched nothing in src/readability.h). Pinned to the immutable v0.6.2 tag, the same instrument gives 412 function pairs, 154 right-direction (37.4%), and the inversion is mechanical: the sign of a function's token-count change predicts the lens's direction in 96.0% of pairs (388/404), with Halstead volume driving 91.1% of the wrong-direction pairs. Source: docs/research/readability-construct-validity.md §3a/§3c on lane/research-readability-validity @9aecbc96. The retracted 484/30.2% figure is kept visible as history in docs/EVALS.md §8 rather than silently replaced. docs/COMMANDS.md is regenerated via docs/docs_commands_build.py, never hand-edited. test/printf_parity.manifest's help_all entry is re-pinned (UPDATE_GOLDEN=1) to the new --help bytes; the verified diff moves exactly that one entry. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
…om shipped help The previous fix for the non-reproducing 484/30.2% figure landed shipped --help text that pointed a reader at `(lane/research-readability-validity @9aecbc96)` and carried an internal label, `MEASURED (t14-cleanup #8, revised)`. Neither resolves for a reader of a released binary, and the research lane may never merge — nothing that ships should depend on an unmerged branch to be understood. --help now states only what it needs to: the pinned v0.6.2 measurement (412 pairs, 96.0% token-count-sign agreement) and how to read a move, trimmed from a nine-line paragraph to six, with the secondary figures (37.4%, 91.1%, the retracted 484/30.2% history) left to docs/EVALS.md §8 where they already lived. README's matching parenthetical now points at EVALS §8 alone instead of the branch/commit. EVALS §8 itself keeps citing the research note's derivation, but by PR (#313, open) rather than by branch name and commit — the standard way to reference draft work that may not land. docs/COMMANDS.md regenerated via docs/docs_commands_build.py; test/printf_parity.manifest re-pinned (UPDATE_GOLDEN=1) — the verified diff moves exactly help_all.

… demotions, fix the idiom disclosure gap reportReusedClones (new-clone-of-reused-helper) already reuses reportNewClones's idiom demotion (CloneIdiomVerdict::demoted) and all-test-script skip (isTestScriptPath) as of 5a31662 — verified ancestor of this branch's own base, landed by an earlier session via train-13. That commit shipped without a dedicated behavioral gate for either demotion on THIS kind, so test/qualitykindscheck.sh's §3 NEW-CLONE-OF-REUSED-HELPER section gains three arms: - 3c: an idiom-shaped collision (the threshold-ladder pair test/cloneidiomcheck.sh already proves demotes `duplication`) containing a preexisting fan-in>=3 helper must demote to sev="minor", not gate — reusing the SAME CloneIdiomVerdict, never a second idiom test. - 3d: a clone group entirely composed of test scripts (a preexisting fan-in>=3 shell helper cloned by a new sibling gate script, both under test/*.sh) must be skipped outright — no row at all. - 3b strengthened into an explicit CONTROL: a genuine, non-idiom, non-test-script reuse-decline still carries gating="1" with no sev="minor"/idiom= — proving the demotions narrow the kind without blunting it. Proved red-first by temporarily reverting quality.h's `vd.demoted` (used `false` unconditionally, matching the described defect) and the allTestScript continue, rebuilding, and confirming both new arms failed (exit 2, gating="1") before restoring the real source. While wiring 3c, found a real gap the T13 fix left behind: quality.h's kFacetAttrs table (the single kind->attribute-name map every emitter — XML, JSON, MCP — reads through facetAttrName) had no entry for "new-clone-of-reused-helper", so a demoted row correctly carried sev="minor" but never printed idiom=, silently dropping the disclosure the legend promises ("the name is printed so the call can be overruled by reading"). Added the missing table row; no emitter branch changes since all three already call facetAttrName generically. Verified: qual*/clone*/legend*/mcp* gate families (71 gates) all pass; qschemetripcheck.sh confirms no kQSnapCacheScheme bump is needed (report-time demotion only, no Snapshot semantics changed); determinism and xmllint hold; --edit-check on facetAttrName/kFacetAttrs reports unchanged contracts. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
…tually spells it The top-level --help summary for --quality-delta listed the ten kinds ending in "reuse-decline", an informal name that never appears in emitted output: the kind= value (src/quality.h), the verb's own legend (src/verbs_quality.h) and docs/COMMANDS.md all say "new-clone-of-reused-helper". A reader of the catalog grepping for what they just saw in a report would not find it in --help. The emitted name wins; renamed the --help line only, never an emitted attribute value. Re-pinned test/printf_parity.manifest with UPDATE_GOLDEN=1 UPDATE_GOLDEN_EXPECT="help_all" — the gate confirmed exactly that one label moved (was red on help_all only before the re-pin, confirming the manifest's own byte-parity check catches this class of drift). Regenerated docs/COMMANDS.md via docs/docs_commands_build.py (never by hand); the diff is the same one-word substitution. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
… and close a pre-existing G4 comment bug MEDIUM (adversarial review rv-slice-defuse): the --help/COMMANDS.md comparative claim about order="defuse" had no in-tree measurement record, and src/slice.h's comment cited docs/research/slice-line-recall.md, which exists only on the unmerged lane/research-arise-slice. docs/EVALS.md now carries the pre-registration (quoted from 48a4f07) and the measured result: population corrected to "478 pairs whose rows hold a gold line" (not "all inventory", which the scratch arm's own label overstated), the before/after/control table at @1/@3/@5/@10/@20/MRR, the control's shuffle spread and paired-bootstrap CI, the per-pair split (182 better / 227 worse / 69 tied — the gain concentrated at @1/@3), and the Python-only, in-sample scope. Both the --help clause and the slice.h comment now point at that section instead of the absent doc, and the --help comparative clause is narrowed to what the table actually shows ("puts a gold line first more often than a random shuffle") rather than the unqualified "ranks above it" the per-pair split does not support. LOW: "distinct sliceable locals" in both legend tiers, --help and the compact "order" reading said locals (bindings) where the code counts distinct binding NAMES on one line (Go `v := v + 1` counts one, not two); reworded to "distinct local names" everywhere it appears. The compact "order" reading also implied every <s> row is reordered by this rule; scoped it to "seed s rows (no v=)" and stated that flow rows keep their own (d=,l=,v=) order, which the full legend already documents. Pre-existing G4 bug, fixed here rather than tracked (both on this lane and on origin/main 15a2085, not introduced by this lane): the --slice-flow full-tier legend's own XML comment mentioned "seed --at=" — a literal double-hyphen inside an XML comment, which xmllint rejects. Every well-formedness arm in slicecheck.sh/sliceflowcheck.sh/sliceflowsenscheck.sh before this commit only linted the DEFAULT (compact) tier, so nothing caught it. Reworded both the full-tier flow addendum and the (unreachable at runtime, but textually identical) compact-branch mirror in sliceLegendText to name the flag without its dashes, matching the house convention already documented throughout graphlegend.h and friends. Swept every other XML-comment -emitting call site in src/ for the same class (adjacent-string-literal join across all 49 <!-- --> sites) and found no other occurrence. Added slicecheck.sh arm (10d): --legend=full well-formedness for plain and --slice-flow=both, proven red against both this lane's pre-fix binary and the reviewer's own 15a2085 build. Re-derived: sliceflowcheck (30b) legend budget 4600/4608 (v1) and 1388/1400 (flow addendum, more headroom than before); printf_parity.manifest re-pins help_all (only label moved, UPDATE_GOLDEN_EXPECT confirmed); docs/COMMANDS.md regenerated; the showcase capture's --legend-dict figure corrected in place to the new dictv (entries unchanged at 704), the same in-place-correction shape c02f8f2 already used for this exact line.

…inary
All three lanes edited src/cli.h help text, so each lane's generated pins
were valid only for its own binary.
- test/printf_parity.manifest: UPDATE_GOLDEN=1 with UPDATE_GOLDEN_EXPECT=help_all;
moved={help_all}, 41 unchanged.
- docs/COMMANDS.md: docs_commands_build.py --bin build/ripwire. The textual
merge carried the slice lane's pre-fix-round dictv=fd7a59c7c536eb85; the
merged binary emits dictv=2d9cec7852fd809b entries=704.
- docs/captures/COMMANDS_showcase_2026-09-14.md: the --legend-dict block's
byte figure recorded 68,575 B, the c02f8f2 value; b19aee6 lengthened the
order= definition by exactly 57 B without re-deriving it. The merged
binary's --legend-dict is 68,632 B on 705 lines (dictv/entries unchanged).

…he default comparator Found by the train-16 full suite: portablebuildcheck #6/#6b failed on src/slice.h's new sliceDefUseRowOrder (std::sort + std::binary_search over vector<string_view>, and std::sort over vector<pair<uint32_t, string_view>>, all with the default comparator, which aborts the Linux G1 leg). The gate was already red at the lane tip b19aee6; the lane's signoff gate list did not include it. This is not a merge interaction. svLess is the same total order operator< defines (infra/sortutil.h), so the emitted row order is unchanged; slicecheck, sliceflowcheck, sliceflowsenscheck and mcpslicecheck pass on the fixed binary.

"Halstead volume drove 91.1% of the pairs where the lens ran opposite the commit's direction (154/412, 37.4%, ran the commit's own direction)" put the right-direction count directly after the opposite-direction clause, so 154/412 read as the population the 91.1% describes. It is the complement. Both counts are now named: 154 (37.4%) ran with the commit, 258 (62.6%) ran opposite, and the 91.1% is of those 258. EVALS section 8 names the 258 too, so the README no longer states a figure its own cited derivation does not. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

…lias Owner decision 2026-09-22: the ordering claim is withdrawn (the flag orders by Halstead volume/token count, not readability), so the NAME was the last thing overclaiming. --biggest-first promises almost nothing and delivers exactly that. - kBoolFlags row renamed to --biggest-first (same Config::readability member; the field itself is not renamed). --readability becomes a hand-written alias (deprecatedReadabilityFlag, same one-shot-per-run stderr shape as deprecatedOrderFlag's --stable/--most-important-last/ --no-auto-order): it still works, is dropped from --help, and prints "ripwire: --readability is deprecated -- use --biggest-first instead" to STDERR exactly once. stdout is byte-identical between the two spellings (proved for the default map, --json and --legend=compact; new gate arm H in test/readabilitycheck.sh, RED on the base binary, GREEN on this one). kHandWrittenFlagArms 22->23, kTotalFlagArms 212->213. - Coordinator-flagged defect in the base lane (readability-withdraw- ordering @ 47725a7): that lane rewrote the one-line --help summary to drop the ordering claim but left the detail body ("LEAST readable first") and the Config field comment asserting it, directly contradicting the same entry's own WITHDRAWN paragraph. Fixed here (src/cli.h ~194/~1383, src/verbs_quality.h dispatch comment, skills/ripwire-fresh-eyes/SKILL.md, the showcase caption) to say what the order IS -- largest Halstead volume/token-count/length first, a size proxy, never a readability order. caught-by: review (train 17 builder), site src/cli.h help block. - Renamed the FLAG only. Left untouched, and confirmed unchanged in the gates that pin them: the emitted XML root <readability>, schema="ripwire.readability/v1", compactlegend.h's rootTag/key/onTag/ onKey, every emitted attribute, and src/lintcatalog.h's unrelated cat="readability" (--lint rule category). --ensemble's and --quality-panel's own emitted legend wording ("readability lens/rank") is unchanged -- it describes the still-unrenamed XML tag, so leaving it is consistent rather than a skip. - README.md, docs/COMMANDS.md (regenerated from this binary), the COMMANDS_showcase_2026-09-14.md caption/heading (hand-edited in place, never re-recorded), present/deck5_ripwire_build.js, skills/ripwire- fresh-eyes/SKILL.md and test/showcase_capture.py updated to the new name; test/deckcheck_allowlist.txt and test/flagsurfacecheck.sh's/ test/helpbudgetcheck.sh's deprecated-alias exemption lists gained a --readability row mirroring --stable's. - CHANGELOG.md [Unreleased]: the rename; PR redhat-et#321's carried-forward entry on the construct-validity caveat's retracted proxy number (closed unmerged, superseded before it shipped); and train 16's three lanes (PR redhat-et#322, merged 2026-09-22, ships in the next release) -- that section was never written. - test/printf_parity.manifest: re-pinned help/help_all only (UPDATE_ GOLDEN=1; confirmed via diff that exactly those two rows moved, twice). Both rows hash the FULL --help/--help=all text, so they move on any wording change to this block regardless of a per-flag entry -- the base lane's own commit re-pinned the same two rows for its own addition to this entry, for the same reason. - Gates naming readability, plus readmedriftcheck/deckcheck/docscommands check/ripwirepubliccheck/dispatchordercheck/helpbudgetcheck/printffmt paritycheck/mcpcontractcheck/gatecountcheck and the mandatory source- grep sweep over this change's file list: green.
