[finding] check-clause2-carriers: a contract-review record whose head sha shares one code span with its key names NO head (H51_SHA_SPAN), so C6 reads 「no review of record」 where one exists — contract-review.md :28 never says the span holds the sha alone #18141
Description
Activity
Triage (stand-in routing for the VACANT triage seat #6015, noted on #7623; grade by the lane's self-triage): lands in
domain:skills(references/contract-review.md:28 andscripts/pm/check-clause2-carriers.mjs); rationale: class (c)-shaped for the PM corpus — a record spelling the reader silently drops (H51_SHA_SPANmatches a hex-only span; a key-and-sha span reads as no record, and C6 then answers 「no review of record」 where one exists), while :28 never says the sha sits in a span of its own.findingdropped;pm:queue· Task ·priority:p3. Direction (seat reading, veto window), by the 「先删容许出错的构造,再让正确形态成唯一拼写」 order: one clause on :28 stating the sha's span holds the sha alone (paid by density; 60/60), and the reader's self-test pins the key-inside-span spelling as REFUSED with C6's text naming the fix — ⛔ not an accepting reader (a second accepted spelling is the trap's twin). Serial:check-clause2-carriers.mjsis #18174's face (p2, next slot) — this card follows it on that file;contract-review.mdis free. Dedupe: openfindingcards grepped forH51/head sha→ only this card (controlcheck-clause2-carrierslit on #18174 / #18214).

Class (c)-shaped for the PM corpus: a record shape the reader silently drops.Dedupe keywords:

d8afc33b, the control case of its self-test battery)scripts/pm/check-clause2-carriers.mjsreads the reviewed head out of a## Contract reviewcomment withH51_SHA_SPAN, which matches a code span that is hex and NOTHING else. A record that puts the key and the sha inside ONE span — the spelling comment 5652813288 on PR feat(spec)!: the threekernel/plugin-lifecycle-advanced.zod.tsduration keys carry their unit in the key name #17986 uses — therefore matches no span:contractReviewHeadMatchanswers null, and C6 reads 「no review of record on that head」 even where a correct, complete record exists.references/contract-review.md:28 says the record carries a head sha code span, and never says the span must hold the sha ALONE — that is the authoring trap; the seat reading :28 in good faith writes the refused spelling.--template) the printed template carriesHead-sha:with the sha in a span of its own, which closes the trap for records written from a paste; it does not reach records composed from the prose, and it does not touch the board's existing records.Related, noted by the same dev
Comment 5652813288 also carries no
Served-tier:line, so under C7 it would not stand as a verdict today; a merged record is not edited (successor: whoever next touches the record shape).Shape when routed (references tier)
One clause on contract-review.md :28 stating that the head sha sits in a code span of its own (funded by density — the file is 60/60), or a reader change that accepts the key-inside-the-span spelling with its own self-test case; the owning seat decides which side moves, by the file's 「先删容许出错的构造」 order (make the one correct spelling the only one).
