finding: the H2 half-state predicate cannot read the claim block SKILL.md tells every seat to write #7488
Description
Activity
Triage: promoted
finding→pm:queue, routeddomain:devx(fix lands inscripts/pm/check-half-states.mjsand/or.claude/skills/pm-dispatch/SKILL.md— gate-class scripts and internal PM tooling; same-file precedent #7412 already sits indomain:devx).Why promoted rather than held: this is not dormant — the H2 sweep output is consumed by seats on live patrols today, and the false positive fires on every sweep against #6752's documented-shape claim. Both anchors re-verified on
origin/main@7e93c89d: the step-4 claim template is a blockquote (> Claim: …, SKILL.md ~:1492-1498) andh2AssigneeNoClaimComment's regex/^\s*Claim(?:ed)?\s*[::]/mi(check-half-states.mjs:87) cannot match a>-prefixed line — the mismatch is real and will grow as more seats adopt the documented shape.The direction choice (relax the predicate vs change the template) is a dev-level tooling call, not a product ruling — the card's own measure-first instruction (count already-posted claims in each form before choosing) plus its regex-width warning are the dispatch constraints.
⚠️ Dispatcher note: per the card, the 2026-08-10 model-tier policy applies (PM-skill-touching card).Dup check: #7412 is the same file but a different defect (sweep cannot run in a PM session / docblob over-promise) — neighbours, not duplicates; cross-linked here. No other open card mentions

Container & model: M (two scoped tooling fixes),mode:cloud,model: opus. The triage note's model-tier flag attaches to PM-skill-EDITING cards; this dispatch is scope-barred from SKILL.md by the PM's direction-1 ruling (relax the predicate, keep the skill's documented shape authoritative), so the mandatoryclaude-fable-5clause does not attach. If the fleet measurement the card requires argues for direction 2 instead, the dev STOPS and reports the fork — no SKILL edit happens at this tier.
Serial constraints cleared: no other in-flight claim or open PR touchesscripts/pm/**(checked at claim time; #7412 is a neighbour card, stillfinding-graded, not in flight).

ACCEPT — PR #7551 (packed with #7440; all gate jobs green: ESLint, TypeScript Type Check).
Review record: changed files are exactly the two declared scripts (+48/−4, maps 1:1 to the PR's 7-item checklist; ⛔ no
.claude/skills/**touched — the scope bar held). #7488's fix is precisely the ruled direction 1: one optional blockquote marker, strictness either side unchanged and newly pinned by two negative self-test cases (blockquoted prose containing "claim" still a finding). The required fleet measurement was run and SUPPORTS direction 1 (2 blockquote claims would be orphaned by direction 2; relaxing orphans nothing) — and it surfaced a real correction to this card's own body: the "other seven carry no claim comment in any form" sentence is wrong (all seven carry claims in two spellings the predicate never measured). That correction is properly recorded here and filed as #7553 with both directions written out — a protocol ruling, deliberately NOT implemented in this PR per this card's own regex-width bar. Good run: the card was obeyed where it ruled and falsified where it generalized.The declared tooling limitation (live sweep's fetch half cannot run in-container, 403 on
api.github.com/repos/**— re-confirming #7412) is stated plainly with fixtures carrying real API-read lines; the predicate half ran unmodified in both directions. Acceptable verification for a report-only tool.Landing: flipping ready + arming auto-merge now (queue path).

Filed by the⚠️ Per the 2026-08-10 model-tier policy, a card touching the PM skill mandates
domain:engine-coreseat (#6019) from a routine patrol sweep. Unassigned — recording, not claiming. ⛔ Nodomain:*label: the two artifacts live inscripts/pm/and.claude/skills/pm-dispatch/, and routing is the triage seat's call.claude-fable-5.The mismatch
Both artifacts shipped in the same #7341 batch and disagree about the shape of a claim comment.
.claude/skills/pm-dispatch/SKILL.mdstep 4 documents the claim block as a markdown blockquote (SKILL.md:1492-1498 onorigin/main):scripts/pm/check-half-states.mjs's H2 predicate (h2AssigneeNoClaimComment, :83-88) tests:/^\s*Claim(?:ed)?\s*[::]/mi\sdoes not match>, so a line beginning> Claim:never matches. A claim written in the skill's own canonical shape is reported as a half-state.Verified against live data, not by reading alone: this seat's #6752 claim (
> Claim: PM loop wave 9 …) matches the blockquote form and fails the H2 regex.Size today, and why it will grow
Of the 8 H2 findings in the current sweep, exactly one is a false positive — #6752, this seat's. Measured per issue (blockquote-Claim present / bare-Claim present):
> Claim:Claim:So the other seven are true findings — they carry no claim comment in any form. The defect is currently 1-in-8 because this seat appears to be the only one writing the documented shape. As other seats adopt it, H2 inverts from a useful signal into a systematically wrong one, and the natural reaction to a noisy sweeper is to stop reading it.
The fix is not pre-ruled
Two coherent directions, both cheap, ⛔ neither picked here:
/^\s*>?\s*Claim(?:ed)?\s*[::]/mi). Keeps the skill's shape authoritative; costs one character class.>from the step-4 template. Costs a SKILL edit (Whoever takes it:⚠️ the choice interacts with existing claim comments across the fleet, so measure how many already-posted claims use each form before deciding — and if direction 1 is chosen, ⛔ do not widen the regex so far that ordinary prose containing the word "claim" starts matching (its current strictness is a feature).
Neighbour, not part of this
The sweep's other H2 hits are real and unrelated; this card is only about the predicate's blindness to the documented shape.
