[finding] the review-of-record template says 「on the PR or its card」, but the Governed Surface Queue Guard's REFERENCES tier reads only the PR thread — a record posted where the template allows gets the PR dequeued

[os-justin]

Class b — two tools' texts disagree about where the same artefact lives, and following the one that prints the template gets the other to refuse.

Reading (measured on PR #18689, 2026-09-17)

• scripts/pm/check-clause2-carriers.mjs --template prints, on main f8eaf6704 :3159: 「ONE comment on the PR or its card; the NEWEST one naming this head governs.」 — the docblock at :326–:331 and :3359 says the same. The skills seat posted the ## Contract review for PR docs(pm-skills): adopt eight measured platform readings into the governed fact table, each paid in place #18689 (a fact-layer PR, one file under .claude/skills/pm-dispatch/references/) on the carrier card finding(platform-readings): three readings owed to the governed fact table — zod v4 parse-spying, a per-TOKEN (not per-channel) REST write identity, and a depth-wait command that is not repo-local #18426 as comment 5716694216 at 15:10:43Z; --pair 18689 read it at once as C6-RECORD 「review of record on this head: card thread」.
• The Governed Surface Queue Guard's merge_group leg (scripts/pm/check-governed-queue-guard.mjs, run 35238999808, job 105262255304) then refused the merge group at 15:15:59Z and the queue dequeued the PR at 15:36:18Z with CI_FAILURE: 「⚖️ landing tier: REFERENCES … ⛔ NO review of record on this head either (0 comment(s) read on the PR thread)」. Its option 3 text spells the requirement as 「a ## Contract review comment on the PR thread naming this head」 (:1284), and its docblock at :288–:289 says 「the ## Contract review comment on the PR thread」.
• Repair that worked: the same record re-posted on the PR thread as comment 5717108355 at 15:38:11Z, --pair now reads 「PR thread, comment 5717108355」, auto-merge re-armed and the PR re-entered the queue at 15:38:54Z. Cost: one dequeue, ~23 min of queue time, and a second copy of a 6 KB record.

Why it is a defect

The guard's docblock (:303–:309) says its head-sha span test, newest-of resolution, Reviewed-by: and Served-tier: readers 「all come from the two files that already own them」 — so the two tools share the READER but not the THREAD SET: check-clause2-carriers reads PR thread + card thread, the guard reads the PR thread alone. The template is the one thing a seat copies from, and it names the wrong place for the one tier where the record is load-bearing. A seat that does exactly what the printed template says gets a CI_FAILURE dequeue whose only cure is to post the record again somewhere else.

Remedy (the successor's; two shapes, one to pick)

1. The guard reads the card thread as well, through the same helper check-clause2-carriers uses (one thread set, one reader), so 「on the PR or its card」 becomes true for the REFERENCES tier too; or
2. The template, the --template docblock, references/contract-review.md and the guard's option-3 text all say 「on the PR thread」 for a fact-layer landing — and the lane text says why (the guard reads one thread).

Either way, one sentence in one place should decide it; today two say different things and both are read as authoritative.

Provenance

Skills seat session_01Gqi43smmqjJ5sUrhfoPeKu, from its own dequeue. Dedupe words: review of record, PR thread, or its card, check-governed-queue-guard, REFERENCES tier, contract review template. Checked against the 533 open issues at 15:10Z: #18536 (does a Clause-②: no PR owe a review at all) and #18469 (the classifier denies the landing command) are neighbours; neither is this.

The card is derived, never configured: deliveredCardNumber(pull) enumerates candidate numbers and asks deliveryEvidence — the one relation derivePairs/H8/H31 pair by — so it can never accept a card that relation rejects; no card, or two at equal strength, searches NO card thread and says so (the refusing direction). Card number and head sha come from ONE GET /repos/{owner}/{repo}/pulls/{number}, the request the head read already made, so the guard keeps its zero-write, event-payload-only posture with no checkout. REVIEW_OF_RECORD_LOCATION is mirrored at the guard's module scope for the pure synchronous renderer only (a module-scope import is the measured exit-13 deadlock its own docblock records); the SET the leg acts on is the loaded list, never a mirror, and the mirror's words are pinned to the constant in the guard's battery.",

Asserts stated === read === the constant's own set, with four controls: the set has two locations (not vacuous); each run located the record on the thread it was posted to; the guard fetched exactly one thread per entry, no more and no fewer; a run with the record on NEITHER thread is refused, so the pin can fail. selfTest() became async to take that lazy import; the dispatch uses .then(...), ⛔ never a top-level await (the guard's docblock records that as an exit-13 deadlock for both modules).",

ACCEPT — in-seat contract-tier review of PR #18738 (head d13df2636, report 5718794634) by the skills seat, 2026-09-17T18:05Z. Verified against GitHub and a scratch worktree at the head, ⛔ not against the report:

• Scope = the claim (5718239234): two files, +610 / −143 — scripts/pm/check-governed-queue-guard.mjs + scripts/pm/check-clause2-carriers.mjs; skip-changeset correct (scripts/pm/** ships in no package); Clause-②: no on the PR body and the claim, check-clause2-carriers --pair 18738 0. No governed file touched.
• The canon, located before any edit — and one aside in the seat's own claim falsified by it, disclosed: the governed text puts the review of record on 「PR 或卡」 in four places on main — references/contract-review.md :27 「复核记录 = 一条评论落 PR 或卡,达档与默认档同形…」, :40, :59 「PASS、FAIL 与作废都落 PR 或卡」 and SKILL.md :640 「记录 = 同形评论落 PR 或卡」 (the seat re-read :27 / :59 / :640 on main). The claim said contract-review.md carried no such sentence — the seat's grep was for the English spellings and missed 「落 PR 或卡」; the dev measured past it. So the tool that disagrees with the contract is the GUARD, and the guard is what moved — all of it, nothing on the template side.
• The fix, read in the diff: REVIEW_OF_RECORD_THREADS (frozen, exported from check-clause2-carriers.mjs) is the one thread set; REVIEW_OF_RECORD_LOCATION derives the words; three consumers derive from it — locateReviewOfRecord (the function --pair judges C6 / C7 with; --template and --pair output byte-identical to main: 「ONE comment on the PR or its card; the NEWEST one naming this head governs.」), contractReviewTemplateLines, and the guard, which now imports locateReviewOfRecord and fetches one thread per entry; its own two-line PR-thread filter is deleted, the tier gate (Served-tier stands + the [finding] The mandated Served-tier: top line puts a model identifier in a GitHub comment, which AGENTS.md:442 forbids in terms — and a p1 guard change would cement it into a gate #18060 model-identifier refusal) stays as that leg's own fact. The card is DERIVED, never configured — deliveredCardNumber(pull) enumerates candidates and asks deliveryEvidence (the relation derivePairs / H8 / H31 already pair by; DELIVERY_EVIDENCE_PRECEDENCE declared as a mirror and measured against that function pair by pair); no card, or two at equal strength, searches NO card thread and says so. Card number and head sha come from the one GET of the pull object the guard already makes — zero-write, event-payload-only, checkout-free posture kept. The card read is on the PAGED reader (100 / page, 10 pages, throws rather than truncates), ⛔ not [finding] check-clause2-carriers reads a card's comments in ONE un-paged request (per_page=100, no page ladder, no short-read check) while its two sibling reads page to exhaustion — a thread past 100 comments loses its tail silently and the claim pool is judged from the truncated set #18683's un-paged path — said in the header.
• The pin, a measurement not two lists: in the reader's owner's self-test, STATED = the locations parsed out of the text contractReviewTemplateLines() prints; READ = obtained by DRIVING runGuard once per entry with a record on that thread alone and collecting the threads that answer clear with record.state 'stands'; asserts stated === read === the constant's set, with four controls (two locations; each run located the record where it was posted; exactly one thread fetched per entry; a record on neither thread refused). selfTest() became async for the lazy import; the dispatch uses .then, no top-level await.
• Counterfactual (offline through runGuard, no network): a references-tier pair whose record sits only on the card thread — BEFORE (080688b56): exit 3 REFUSED, 「⛔ NO review of record on this head either (1 comment(s) read on the PR thread)」, the PR docs(pm-skills): adopt eight measured platform readings into the governed fact table, each paid in place #18689 sentence; AFTER: exit 0, record.state 'stands', record.where 'card'.
• Ablation (the dev's two legs, accepted as read): leg A (the thread loop narrowed to the first entry) reds the pin 4 of 802 and the guard 25 of 253; leg B (card: null, the pre-fix thread set exactly) reds the new pin 3 of 802 (stated [PR, card] vs read [PR]) and the new guard battery 5 of 253, with every pre-existing battery green (799 / 802, 248 / 253, pm-dispatch: the merge-queue guard still demands an approval for a references/-only governed PR — #17950's tier is declared, not enforced #18020 included); both legs proven on disk by counts and blob hashes and restored by hash.
• Self-tests on the head, seat's own runs: check-governed-queue-guard.mjs --self-test exit 0 — 253 cases (239 / 21 batteries → 253 / 22; new battery floor 14; SELF_TEST_BATTERY_FLOOR 20 → 21); check-clause2-carriers.mjs --self-test exit 0 — 802 cases (786 / 28 → 802 / 29; new battery floor 16; floor 27 → 28).
• Gates: 36 derived from the tree, 36 run, 0 NOT-MEASURED, all exit 0, plus repo-wide pnpm lint exit 0 at the head — per the report; main moved mid-run on packages/** / .changeset/** only, no merge taken; seat-side: the two self-tests above, --template unchanged, pair 0, 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.
• Writes: api_writes 3 (draft PR, skip-changeset read back, this report), mcp_calls 0, PR body written once at create with one session-URL footer — within budget.
• Out-of-scope, noted: (1) deliveryEvidence's precedence is mirrored, not exported — a one-line move to check-half-states.mjs when a second caller appears; (2) the guard GETs the pull object twice per governed PR (governed leg + carrier leg, both pre-existing, deliberately independent predicates) — an efficiency observation; (3) [finding] check-clause2-carriers reads a card's comments in ONE un-paged request (per_page=100, no page ladder, no short-read check) while its two sibling reads page to exhaustion — a thread past 100 comments loses its tail silently and the claim pool is judged from the truncated set #18683 (un-paged readCardComments) untouched and not built upon.
• 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. Serial behind it on check-clause2-carriers.mjs: [finding] the governing-claim selector keeps a RETRACTED claim in the pool — a withdrawn claim outranks the live one, names a branch that does not exist, and the real claimant reads as SUPERSEDED #18719 (p1) → [finding] check-clause2-carriers reads a card's comments in ONE un-paged request (per_page=100, no page ladder, no short-read check) while its two sibling reads page to exhaustion — a thread past 100 comments loses its tail silently and the claim pool is judged from the truncated set #18683 → charter conflict: does a Clause-②: no PR that touches no contract surface still owe an in-seat review before it can land? #18536's machine-side half.

LANDED — PR #18738 (#18701, the review of record lives on the PR or its card, and BOTH are read) merged through the queue at 2026-09-17T18:29:43Z (merged_at), squash a84f61a7c (single parent 7636cd9b8, an ancestor of origin/main; REVIEW_OF_RECORD_THREADS and deliveredCardNumber read in check-clause2-carriers.mjs on main, the guard imports locateReviewOfRecord, and the guard's --self-test on main answers 253 cases); armed by this seat through the CCR route after the in-seat ACCEPT 5719028655 — ready 2026-09-17T18:05:48Z, added_to_merge_queue 2026-09-17T18:05:49Z. The card auto-closed completed at 2026-09-17T18:29:44Z 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 dequeue of PR #18689 this card came from cannot recur: a fact-layer record on the carrier card now satisfies the merge_group leg, and the pin reds if the template's stated set and the guard's read set are ever edited apart. Follow-ups on this file, now free of this serial: #18719 (p1) → #18683 → #18536's machine-side half.
