finding(scripts): check-lint-coverage's ratchet banner says in the present tense that the closing-keyword shape "still stands" in two named gates — one half was already false, the other goes false when objectui#9898 lands #9906

   Worktree: objectui-issue-9906
   Domain: domain:devx
   File surface: scripts/, .changeset/ (stop on breach; explain in the report)
   Container & model: objectui carries no scripts/pm/dispatch-gates.mjs, so there is no tier output to quote and this seat invents none; mode:subagent, model inherited from this seat.
   Clause-②: no
   Thread-read: 5732662796
   Serial constraints cleared: measured at 18:2xZ over all 15 open PRs (1941 filenames, 1902 distinct paths; control .github/workflows/ci.yml -> [9584] fired) — scripts/check-lint-coverage.mjs, scripts/check-type-check-coverage.mjs, scripts/check-action-forward-parity.mjs and scripts/check-spec-symbol-derivation.mjs are each absent from that index. Merged predecessor objectui#9898 (15:18:23Z) is the card's own sequencing precondition and it is met.

   Premise re-run by this seat, with the ruler triage ordered

   The grading comment above says its own probe measured the wrong thing — it counted ${prefix}/${entry.name} template literals as closing keywords — and then says, correctly, ⛔ do not use that ruler; re-run with the CLOSING_TRIGGER the pins share. Done, on main = f5e2fcb4a:

   /\b(?:close[sd]?|fix(?:e[sd])?|resolve[sd]?)\s+(?:[A-Za-z0-9-]+\/[A-Za-z0-9-]+|objectui|objectstack)?#(?:\$\{|\d)/i
   

   file the banner names in the present tense	hits
   scripts/check-action-forward-parity.mjs	0
   scripts/check-type-check-coverage.mjs	1 — at the source comment reading the fix objectstack#4074 applied in `types`, a noun, ⛔ not an emitter

   ⇒ both halves of the sentence are false today, which is what the card predicted would happen once objectui#9898 landed. It landed.

   ⭐ For completeness, the file the banner calls the landed precedent, scripts/check-spec-symbol-derivation.mjs: 1 hit, inside a template literal that builds an emitted message — (and close #${CLAIM_DEBT_ISSUE} once the ledger is empty). That one is an emitter surface carrying a bare #${…} anchor, consistent with the banner calling it the precedent.

   ⚠️ A correction the card needs before anyone starts

   The card says the trigger is "the CLOSING_TRIGGER regex the four landed pins in this family share byte-for-byte." Measured across scripts/__tests__ on main = f5e2fcb4a, the literal is declared in five files, and all five declarations are byte-identical (one distinct literal, md5 equal):

   • check-action-forward-parity-closing-keyword.test.ts
   • check-lint-coverage-closing-keyword.test.ts
   • check-type-check-coverage-closing-keyword.test.ts
   • spec-symbol-ledger-anchor-liveness-9537.test.ts
   • spec-symbol-ledger-plugin-detail-7265.test.ts

   The finding is unaffected — the ruler is the same ruler either way. ⚠️ But this seat published a wrong count of its own one round ago and the lesson was 「before publishing a COUNT, grep for it」, so it is stated rather than smoothed.

   ⛔ Five byte-identical copies of one regex is a separate observation and is ⛔ NOT this card. It is not in the declared surface, and the 2026-09-18T03:58Z ruling's standing direction is no further gate development. ⛔ Do not widen into it; if it deserves a card, this seat files it after the round.

   What the delivery owes, from triage's own words

   ⛔ Not a delete — the banner is explaining a deliberate trade-off (why the anchor is spelled objectui#). Either restate it as a point-in-time reading with its timestamp, or as something that cannot rot (point at the pin rather than recite two files' state). And:

   ⭐ 而这个文件自己已经有一条 pin(scripts/__tests__/check-lint-coverage-closing-keyword.test.ts,横幅逐字说它「reads this module's text rather than trusting this comment」)⇒ 交付要让那条 pin 也覆盖这句主张,否则同一句话下次还会腐烂。

   ⭐ That pin already reads the banner region — staleEntryRatchet() slices the gate source from the ratchet banner to the report banner — so covering this sentence is an extension of what it does, ⛔ not a new gate.

Both halves of the banner's present-tense claim are false, as the card predicted once objectui#9898 landed. Took triage's SECOND route (cannot-rot) rather than the timestamped reading: the banner keeps the trade-off it exists to explain and keeps the scope record as history, and no longer answers from there which other gates carry the shape; the precedent moves to the pin, which already records it by the names of the things. The gate's own pin is extended, not replaced: within the rule-2 region no gate may be cited but this one and its pin, in any of three spellings (source file, pin file, package script key) with the directory prefix optional. No tree is scanned and none may be - the 2026-09-18 ruling forbids it, and this is deliberately the weaker rule.

ABLATIONS from the COMMITTED state (HEAD blob fa7d4f9c1), each mutation proved on disk by occurrence counts both directions plus git hash-object differing from the HEAD blob, each restored under a trap and the restore proved by the blob returning to fa7d4f9c1 with `git diff HEAD` empty: baseline 6 passed; A (removed sentence verbatim) 2 failed|4 passed; B (bare filename, no scripts/ prefix) 2 failed|4 passed; C (package script key, no filename) 2 failed|4 passed; D (scanned slice collapsed) 2 failed|4 passed with the slice guard's own message 'the ratchet slice no longer reaches the banner it is scanning'. NOTE: a first ablation attempt ran BEFORE committing and its `git checkout HEAD --` restore wiped the uncommitted repair; that reading was discarded, the repair re-applied and committed, and every number above is from the re-run.

   Landed — PR objectui#9937, merged 2026-09-18T20:02:19Z, squash d6a84446f

   Card released: pm:dispatched removed, assignee cleared, read back MATCHES (priority:p3, tooling, domain:devx, no assignee). Closed completed by the PR's Fixes line. Two patch rounds, both this seat's review.

   Landing probe on main = d6a84446f

   Each token names what must be PRESENT or what must be ABSENT — ⛔ never a word that appears in both outcomes.

   token	expectation	result
   the non-rotting wording (Such a sentence does not stay true; it only waits.)	present	OK
   the removed present-tense tree claim	absent	OK
   the false clause, in any of its spellings, across gate and pin	absent	OK
   the scope record kept as history, citing objectui#9595	present	OK
   any other gate named anywhere in the rule-2 region	absent	OK
   the pin's foreignGateCitations extension	present	OK
   the corrected reading in the pin's header	present	OK
   any tree scan added to the pin (readdirSync, glob)	absent — the 03:58Z ruling bars it	OK

   Control, with its reason: the shared CLOSING_TRIGGER in this pin is unchanged. The round re-measured the tree with that ruler and left the ruler alone, so a ruler that had moved would mean the artifact rewrote the instrument it had just cited.

   Errata 62b, tested by ancestry: M^ = 0c789a402, compare M^…head = diverged (ahead 4, behind 4) ⇒ FIRED.

   ⛔ Two patch rounds, one clause, three homes — the round's real finding

   The repair's own new prose asserted that the sentence it was removing "was false in one half the day it was written." Measured at ff29450a9 (the commit that wrote it, merged 2026-09-16T15:29:06Z): check-action-forward-parity.mjs 2 emitter hits, check-type-check-coverage.mjs 3. ⇒ both halves were TRUE that day. The sentence rotted ~35h later in two steps — objectui#9755 at 02:20:13Z killed the first half, objectui#9898 at 15:18:23Z the second, ⛔ neither of them this pull request.

   ⭐⭐⭐ A repair reproduced the defect it was removing, inside a banner whose entire subject is 「⛔ do not assert a tree reading here」.

   And it took two rounds because the clause had three homes:

   1. the banner — caught by this seat's first review;
   2. the changeset — caught by the os-dev seat, ⛔ not by me, and it would have published verbatim into the CHANGELOG;
   3. the pin's own assertion failure message — caught by this seat's second review, 154 lines from a header that already recorded 「a first draft got it backwards」.

   ⇒ ⭐⭐⭐ A correction can land in the narrative and miss the emitter. ⛔ When a defect is a STRING, review the string across the whole diff, ⛔ not the site you noticed it at.
   ⚠️ And this seat's probe for it fired on two legitimate hits — a pre-existing docblock line, and the header sentence that records the miss. ⇒ the standing rule again: name the thing that must be ABSENT, ⛔ not a word that appears in both outcomes.

   ⭐ What the delivery chose, and why it is the right shape

   Triage offered two routes: a point-in-time reading carrying its timestamp, or a restatement that cannot rot. The dev took the second, on root AGENTS.md commandment #9 — point at the instrument that re-derives a figure and ⛔ never write down its answer, because a figure that is still correct is the dangerous case. Its own false clause then proved the argument by being committed rather than argued.

   All three things triage said not to lose survive: the trade-off the banner exists to explain, untouched; the scope record, kept as history; the precedent, moved to the pin beside the code that reads it. The pin asserts 「the banner does not make the claim」 rather than 「the claim is true」 — the only version that needs no population and scans no tree.

   ⚠️ CI: red on a failure that was ⛔ not this pull request's

   Test (shard 1/4) hit the timeout-minutes: 20 ceiling at 20m16s and was reported cancelled. Stood down publicly (comment 5735054506) rather than silently, and the one re-run this case allows was spent. It came back 1167s — a 33-second margin.

   ⭐⭐ Same job, same commit, same code: 1216s then 1167s. A 49-second swing straddling the ceiling ⇒ whether a pull request goes red here is decided by noise, ⛔ not by its diff. 🧑 That is objectui#9584's subject, and it is now measured rather than predicted.

   ⛔ Turned back, ⛔ not widened into

   Five byte-identical CLOSING_TRIGGER declarations under scripts/__tests__ — the card says four. ⛔ Not consolidated: outside the surface, and the 2026-09-18T03:58Z ruling bars new gate development. Also untouched: the sibling gates themselves, and this gate's leading docblock citation of its sibling (judged a standing architectural relation, ⛔ not a rotting reading, and recorded in the pin's header as the scan's declared boundary).

   ⛔ No dwell figure is published for this round, for the same reason as R78: the enqueue's added_to_merge_queue event is unreadable here, so the clock that would anchor a dwell cannot be read. ⭐ A figure whose source you could not read is not a figure.
