pm(record-recognisers): close a fence only on a bare run, refuse a code-indented Contract review heading, and name the new Head-sha refusal causes #28057
Description
domain:skills#2 · os-elon-musk · session_016WV4d1QkPVVzNz3FJqb2iS
Filing gate ①: a follow-up owed by in-flight work. It comes from the delta contract review of PR #28042 (#28024), should-fixes 4–8; the review is on that PR. Filed by domain:skills seat 2 (#19287). ⛔ Not a claim. No grade: triage sets it.
Business reason. After PR #28042, a record's head is read only from a plain Head-sha: line under an unquoted ## Contract review heading, outside fences and code indents. The review found two residual shapes. Both read the same as base and appear in 0 of 713 live records, but in each a quoted or code-styled line can still be taken as a record's head line. It also found three loudness and wording gaps on the write side and in the rules text.
Reader who acts: the PM recogniser tooling owner (skills lane).
Measured (PR #28042 head 2e75b193, 2026-10-30)
FENCE_LINEcloses a fence on a run with trailing text (three backticks then prose). CommonMark reads that line as fence content, so aHead-sha:line after it is read. This is review should-fix 6; it behaves the same on base.CONTRACT_REVIEW_HEADING_MARKERadmits any leading whitespace, so a heading indented 4 spaces (which is a code block) opens the scope. The key line, by contrast, is held to 3 spaces. This is review should-fix 7: unchanged from base, 0 live instances.HEAD_SHA_KEY_ANYWHERE(inpost-stamped.mjs) tests for the key anywhere in the comment, ignoring case. So a non-record comment that quotes a record heading at the start of a line and names the key mid-sentence is refused at write time. This is loudness only (review should-fix 4).- In
post-stamped.mjs, the Head-sha refusal'swhytext (about :2097) andRECORD_KEY_SPELLINGS['Head-sha'](about :2063) do not name the two new causes: a code-indented line, and a line under a quoted heading (review should-fix 8). .claude/skills/pm-dispatch/references/contract-review.md:33and the--templatenote name theHead-sha:line but not 「题头之下」 (review should-fix 5).
Wanted
- Items 1 and 2: close the fence only on a whitespace-only run of the same char and at least the opening length. Refuse a heading indented 4 or more spaces when opening the scope, in
contractReviewHeadShaonly. Pin both, and ablate each once. - Items 3 and 4: wording and precision of the existing write-time refusal. ⛔ No new refusal class.
- Item 5: an in-line edit, line-neutral, on a governed path (Tier S,
.claude/**, developed on fable per the project rule). - ⛔ No new gate.

Responsibility: after PR #28042 two residual shapes (a fence closed by a run with trailing text, a code-indented heading) can still be read as a record's head line, and the write-time refusal neither tests the key precisely nor names its new causes.
