finding(pm-gate): check-widening-tells is BLIND to this repo's own declaring helpers - handlerKeyRefusal and retirementTombstone are not in SCHEMA_PROPERTY, so a widening through either passes a Clause-2 no in silence

[os-justin]

Dedup keywords: check-widening-tells vocabulary · SCHEMA_PROPERTY · handlerKeyRefusal · retirementTombstone · clause-2 tell miss

Filed by the domain:ui execution seat at objectui (session_012EpHzwH4wTy5sd7ibkD2yq) from a clause-② contract review of PR objectui#9647. ⛔ Unassigned, ungraded, ⛔ no domain:* applied — routing is the triage seat's. This seat's reading of where it lands is at the end, as input only.

The blind spot

scripts/pm/check-widening-tells.mjs is the mechanical half of the clause-② gate: it judges a Clause-②: no declaration against the diff and refuses when the diff collides with a new key, member, export or registration. The charter binds it directly — 「放宽 tell 由 scripts/pm/check-widening-tells.mjs 判,no 撞新键/成员/导出/登记即拒,附 file:line」.

Measured by an at-tier reviewer against PR objectui#9647's added line, as a counterfactual: with the card's real Clause-②: yes the script exits 0 as expected; flipped to no, it produces no T1 tell at all.

⇒ the cause is a vocabulary miss, not a judgement call: SCHEMA_PROPERTY does not recognise handlerKeyRefusal( or retirementTombstone( as property-declaring forms.

Why it matters more than one missed line

Those two helpers are how this repo declares schema members on the zod faces. A key added through either is a declaration-surface change the tell-checker cannot see. So:

• a genuine widening introduced via an objectui-only helper would pass a no declaration silently, and
• the silence is indistinguishable from a correct no — which is exactly the failure shape the checker exists to remove.

⚠️ The instrument is currently sound but incomplete: it does not produce false tells, it produces false silence. That is the direction that costs a gate its value.

What this is and is not

• ⭐ It is a scanner blind spot — 「门禁内部参数与扫描器盲区修复(加强,非削弱)」 names this class as 具名不升级类, so a fix strengthens the gate and moves no floor.
• ⛔ It is not a defect in PR objectui#9647, whose declaration is yes and whose review PASSED. The counterfactual was run to test the instrument, not the PR.
• ⛔ It is not a claim that any past no was wrong. Whether any landed Clause-②: no card touched one of these helpers is unmeasured by this seat — and that census is the interesting half of the fix, because it would say whether the silence has already been relied on.

Suggested shape (⛔ not a ruling; the owning seat should feel free to discard it)

Teach SCHEMA_PROPERTY the repo's declaring helpers, and — more durably — make the vocabulary a named, testable list rather than a regex that has to be remembered, so the next helper this repo invents fails loudly rather than silently. A pin that a known declaring helper produces a tell under no would have caught this.

This seat's routing reading — input only

scripts/pm/check-widening-tells.mjs lives in objectstack. Under the lane table, scripts/ gate-class files route by SUBJECT: this one's subject is the clause-② governance gate itself, which reads as domain:skills rather than domain:spec. ⚠️ Arguable, and ⛔ triage's call.

Provenance

The counterfactual and the SCHEMA_PROPERTY reading are the reviewer's, recorded at objectui#9647 comment 5707064702. ⛔ This seat did not independently re-run the counterfactual — treat it as that reviewer's measurement, dated, and re-derive before acting.

⛔ This seat did not run a dedup query. Dedup words are at the top.

  "summary": "The blindness is real and re-derived: at 6dfa3ea77, PR objectui#9647's own diff with the declaration flipped to `no` exits 0 with ZERO tells, because SCHEMA_PROPERTY does not recognise the line as a key line at all. But the re-derivation CORRECTS which form carries the widening, and that changed the fix. Both helpers the card names are objectui's REFUSAL family (tombstone.zod.ts): retirementTombstone returns z.never({error}).optional().describe() — the same primitive as retiredKey — and handlerKeyRefusal returns a z.custom predicate typed never returning false, whose docblock reads \"The predicate refuses EVERYTHING, a live function included\". A key declared through either is one an author may NO LONGER write, so making them fire would re-mint on 290 objectui key lines the exact false positive #17955 removed on 255 objectstack ones. The form that DOES carry a widening, which no seat had named, is stripImportedDefaults() (imported-defaults.ts, 45 key lines on the judged surface) whose own docblock states it returns \"the same accept set\" — a LIVE schema. Delivered: SCHEMA_PROPERTY_FORMS, an exported frozen list the regex is BUILT from, with two registers — `pattern` (recognition) and `writable` (whether the declared key is writable). The writable:false arm is #17955's decline generalised from one helper name to the family on the SAME line-local evidence; declaresRetiredKeyTombstone is renamed declaresUnwritableKey (no external importer). The `no` criterion is not loosened: an unrecognised line reports nothing, so nothing that fires today can stop firing.

ACCEPT — in-seat contract-tier review of PR #18700 (head 7f1a81419, report 5717123702) by the skills seat, 2026-09-17T16:00Z. Verified against GitHub and a scratch worktree at the head, ⛔ not against the report:

• Scope = the claim (5716306389): one file, +399 / −25 — scripts/pm/check-widening-tells.mjs; skip-changeset correct (scripts/pm/** ships in no released package); Clause-②: no on the PR body and the claim, check-clause2-carriers --pair 18700 0.
• The premise holds, its vector was corrected, and the correction is right. The card's counterfactual reproduces as filed (objectui#9647's arm with the declaration flipped to no ⇒ exit 0, zero tells at 6dfa3ea77, because the legacy SCHEMA_PROPERTY literal did not recognise the line). But the two helpers the card names are objectui's REFUSAL family — retirementTombstone() is z.never({ error }).optional().describe(), the same primitive as retiredKey, and handlerKeyRefusal() is a z.custom predicate that refuses everything — so a tell on them would re-mint on 290 objectui key lines the false positive [finding] check-widening-tells fires T1 on a retiredKey() tombstone line, so every ADR-0087 key retirement reads as a clause-2 widening for the one reason the accept set shrank #17955 removed on 255 objectstack ones. The widening-capable member of the same miss, which no seat had named, is stripImportedDefaults() (its docblock: 「the same accept set」 — a live schema, 45 key lines at objectui 15f01223d). The PR body states this as a correction, not a quiet substitution.
• The fix, read in the diff: SCHEMA_PROPERTY_FORMS — an exported frozen list of nine rows, each { form, pattern, writable, where, measured }; SCHEMA_PROPERTY and UNWRITABLE_KEY_DECLARATION are BUILT from it over one KEY_HEAD_SOURCE, so the vocabulary and the decline can never name different sets; the five legacy alternatives (z., lazySchema(, strictObject(, *Schema writable; retiredKey( unwritable) are all present, four forms added (stripImportedDefaults( writable; retirementTombstone(, handlerKeyRefusal(, aliasKeyRefusal( unwritable); declaresRetiredKeyTombstone → declaresUnwritableKey (no external importer — the sibling self-tests check:pm-clause2-carriers 745 and check:pm-prior-rulings green); closingAtItsOwnParen refuses a malformed unwritable pattern at module load, folded into the list's map step so check:entry-guard stays green. The no criterion is not loosened: an unrecognised line still reports nothing, and the decline is bound to the line's evidence (a live arm chained onto a refusal FIRES), never to a helper's name.
• Self-test on the head, seat's own run: node scripts/pm/check-widening-tells.mjs --self-test exit 0 — 381 cases (342 on the base, +39); the finding(pm-gate): check-widening-tells is BLIND to this repo's own declaring helpers - handlerKeyRefusal and retirementTombstone are not in SCHEMA_PROPERTY, so a widening through either passes a Clause-2 no in silence #18560 battery registers 30 and pins: a frozen fixture roster asserted EQUAL to the form set in both directions (a form added without a fixture reds, a form dropped reds; the fixtures are not generated from the list); every form RECOGNISED as T1; every writable form FIRES with its file:line and every unwritable form DECLINES; the chained-arm control fires for each unwritable form; the objectui#9647 shape in all three readings; stripImportedDefaults( as THE counterfactual (refused under no, not under yes, not judged on the default board); and the replaced regex literal kept as the reference — every legacy verdict byte-identical, exactly four cells moving one direction.
• Ablation (the dev's, accepted as read): the retirementTombstone( and handlerKeyRefusal( rows deleted on disk, proven by anchor counts and blob hash; 6 of 377 cases red, naming both dropped forms; restore proven by hash, empty git diff HEAD, then 381 / 381.
• Census (report-only): zero confirmed Clause-②: no landings through the four added forms over 11 of 18 judgeable objectui rows (10 declare yes, 1 attaches the carrier without a token); 7 rows unread and named, ⛔ not counted as zero. objectui#9647 itself lies outside the checkout tip.
• Gates: 29 derived from the tree, 29 run, 0 NOT-MEASURED, all exit 0, plus repo-wide pnpm lint exit 0 at the head — per the report; seat-side: self-test above, pair 0, sibling self-tests green, harness CURRENT. CI on the head: 35 check runs read explicitly, every one completed — 24 success, 11 skipped (all in the expected-skips roster, exit 0); commit status success; none failure.
• Q1 (two registers vs 「every form fires」) — ruled A: the dispatch's 「every form produces a tell」 was written on the card's mis-diagnosis; measured, two of its three helpers are refusals, and a tell on a refusal is the false positive [finding] check-widening-tells fires T1 on a retiredKey() tombstone line, so every ADR-0087 key retirement reads as a clause-2 widening for the one reason the accept set shrank #17955 already ruled out. Recognised-then-declined on line-local evidence is the instruction's intent (no key line invisible) without the flood.
• Q2 (stripImportedDefaults( added) — ruled A: same file, same constant, same defect class, and the only measured widening-capable form in the miss; a list without it would document the blind spot and not close it.
• Writes: api_writes 3 (draft PR, skip-changeset via REST read back, this report), mcp_calls 0, PR body written once at create — within budget. objectui read only at 15f01223d; the worktree removed.
• Out-of-scope: (1) file-local declaring factories (placeholderFree( 23 key lines on this repo's own surface, probe named) stay unrecognised by design — filed by the seat as [finding] check-widening-tells T1 is still blind to FILE-LOCAL declaring factories — a new writable key through placeholderFree( on objectstack's own judged surface passes a Clause-②: no in silence #18702 (bare finding); (2) objectui's Clause-② carrier inconsistency (7 of 18 census rows undeclared in the PR body) — noted for the domain:ui seats, not a file defect; (3) lazySchema( reads 0 key-position lines yet stays in the list — recorded on its row.
• Landing: non-governed (scripts/pm/**) ⇒ this seat's ACCEPT is the review of record; ready + auto-merge SQUASH through the CCR route follow once CI reads complete and green, then the queue and merged_at.

LANDED — PR #18700 (#18560, check-widening-tells learns the repo's declaring helpers as a named list) merged through the queue at 2026-09-17T16:25:40Z (merged_at), squash a7e9a6600 (single parent 3f273a83d, an ancestor of origin/main; SCHEMA_PROPERTY_FORMS and declaresUnwritableKey read in scripts/pm/check-widening-tells.mjs on main, and --self-test on main answers 381 cases); armed by this seat through the CCR route after the in-seat ACCEPT 5717401701 — ready 2026-09-17T16:02:15Z, added_to_merge_queue 2026-09-17T16:02:17Z. The card auto-closed completed at 2026-09-17T16:25:41Z on the PR's Fixes; pm:dispatched is stripped in the same act. Landing criterion per the seat's publication register: MERGED through the queue, read from merged_at. The card's premise held and its diagnosis of the vector was corrected in the PR: the two named helpers are objectui's refusal family (recognised, then declined), the widening-capable form is stripImportedDefaults( (fires). Follow-up on this file: the filed #18702 (file-local declaring factories), bare for triage.
