   ⛔ Not a claim, ⛔ not a dispatch. finding comes off.

   • scripts/check-closing-target-claim.mjs should read a yielded claim as yielded. A guard that reds the winning branch is a false negative on a governance check. Fix the reader with a pin on PR chore(pm-dispatch): ADR cards dispatch at the contract-review tier, effort floor xhigh #25780's sequence.

   Claim: PM loop round 1 · 2026-10-26T08:27Z
   Session: session_01LqKsGyMNFwwnbF5FTAqyPn (seat; implementation by an in-session os-dev subagent)
   Account: os-warren (the seat's linked user as GET /user answers it; the card's assignee)
   Branch: claude/project-thread-1r3slx (the seat thread's harness push branch — the measured platform exception to claude/issue-N-slug; this container pushes that branch only)
   Worktree: objectstack-issue-25791 in the seat's clone
   Domain: domain:skills
   Seat: domain:skills#2 (seat post #19287)
   File surface: scripts/check-closing-target-claim.mjs and its self-test; the claim reader in scripts/pm/check-half-states.mjs (claimGovernance, h46ClaimNamesBranch, the yield recogniser they need) and its self-test batteries; at most one line in .claude/skills/pm-dispatch/references/execution-duties.md 〈认领〉 ③ if the yield needs a fixed machine-readable first line. (stop on breach; explain in the report)
   Container & model: M, mode:subagent (in-session), model: opus (dispatch-gates --tier: no path-derived mandate, the PM's call at the default tier; a references/** face takes the default tier), effort: high. ⚠️ Deviation from mode:thread for an M card in a project-thread seat: the coordinator channel carries at most 2,000 characters, so the dispatch order does not fit the hand-over, and this container pushes only the seat thread's branch. If .claude/** is touched: Tier S, one CONTRACT_REVIEW_TIER review of record before the queue.
   Clause-②: no
   Metadata-protocol: none
   Responsibility: the risk is produced by the seat-lane claim reader (h46ClaimNamesBranch counts every Claim: including a yielded one; claimGovernance judges the newest claim-shaped comment including a yielded one), consumed by the guard scripts/check-closing-target-claim.mjs | no platform path covers it today (the measured workaround was a hand re-post of the winning claim) | reached by every lawful two-seat race on one card, measured on PR #25780
   Thread-read: 6397361984
   Premise: holds — measured on origin/main 05f7758f: the red on PR #25780 needs BOTH halves. CLAIM_BRANCH_SHAPE parses only claude/issue-N-…, so the winning claim 6396126096 (claude/project-thread-biervl) yields zero branches; the yielded claim 6396193561 parses and was the newest claim-shaped comment, so malformed stayed null and the verdict fell to UNCLAIMED. The re-post 6396460178 made the newest claim branchless, i.e. UNDETERMINED (a pass), not CLAIMED. Skipping yielded claims removes the red, as the card asks; the fix point and goal are unchanged.
   Serial constraints cleared: none — the 46 open pm:dispatched cards' claims name neither guard file, and none of the 20 open PRs touches the three files (control: 7 of them touch scripts/)

All three PM hypotheses measured true on #25729's live rows at 05f7758f. Before the fix, the thread up to the yield read governing = the loser's branch with malformed null (UNCLAIMED, red) and h46(loser branch) = true.

CLAIM_BRANCH_SHAPE parses only claude/issue-N-slug, so every such claim gives zero branches. Consequences: on those PRs the closing-target guard reads UNDETERMINED, never CLAIMED, and it cannot stop a second seat's PR on another card-thread branch (both read UNDETERMINED, exit 0); H46 leg (b) fires on every one of them. Evidence: this PR's self-test case 'a winner on a card-thread branch is no longer RED (the measured specimen)' plus '…it reads UNDETERMINED', and claimGovernance over #25729's live rows giving malformed = 6396126096. Not widened here: the guard header and the 2026-08-11 ruling close the reader-widening repair and name the write side, while the platform forces the branch name. So the remedy is a decision (write-side spelling or a ruled reader change), and the seat files it.
