finding(skills): the seat's claim-time serial check reads open PRs' file lists only, so a sibling card already claimed and pushed but not yet opened as a PR is invisible to it — one git ls-remote --heads origin | grep <file stem> would have shown #18314's branch before #18844 was claimed

Ruled: 5780497628 · letter B · 2026-09-22T16:53Z — batch #214 item 1, maintainer 「开始处理决策卡」; state pm:queue — the one-word SKILL.md deletion (B), ⛔ no runbook line (A / C not taken)

Filed by the domain:skills execution seat (session_01BTeBejoPUvRHN8WdAJC6oF, seat post #7623) at 2026-09-18T08:00Z, on its own miss (the double dispatch of #18844 beside #18314; the triage half is filed bare for the triage round). This lane's finding is self-triaged (lanes/skills.md); grading follows in the first comment.

Dedupe words: claim pre-check ls-remote file stem · serial constraints open PR files only · claimed branch no PR invisible · shadow scan at claim time · 18844 18314 double dispatch seat half.

Class (b) — the claim's own field says 「Serial constraints cleared」 on a reading that cannot see the case

The seat's Claim: template (every claim this shift, e.g. 5726072431) clears serial constraints by reading every open PR's file list for the target file. A sibling card that is pm:dispatched with a pushed branch and no PR yet — the state #18314 was in from 05:50Z to 06:56Z — matches no open PR, so the check reads FREE and the claim proceeds. Measured on the instance: at the 06:21Z scan there were 22 open PRs and none touched scripts/check-single-claim-paths.mjs; git ls-remote --heads origin at the same instant would have listed claude/issue-18314-single-claim-paths-proxy… (pushed 05:5xZ). AGENTS.md rule 2's own pre-check (git ls-remote --heads origin | grep -E 'issue-<n>(-|$)') is keyed by card NUMBER, which cannot find a sibling under another number; the file's STEM is the key that would.

Done when (⛔ a proposal, measure)

The seat's claim pre-check adds one read: git ls-remote --heads origin | grep -i '<file stem>' for each target file (stem = the basename without extension), and a hit on another card's branch is a shadow ⇒ SKILL.md :367 applies (Blocked-by:, no dispatch) or the two seats converge on one entry. Where the spelling lives is the taker's measurement: the claim template is seat practice (the seat post's Notes), the rule may belong on references/dispatch-runbook.md beside the serial-queue lines — governed fact layer, 241 / 241, paid in-file.
Counterfactual named in the row: a branch pushed under a non-protocol name (copilot/fix-…) still carries the stem in most spellings; a branch named by number only does not — the check catches the common case, the Claim: comment on the sibling card is the other reading.

Ruling: batch #214 item 1 · letter B · maintainer 「开始处理决策卡」 · 2026-09-22T16:52Z

Director seat, summon #27, session_0129ZpnaBcYZZ51rCvQiXg6C. Batch #214 was presented in chat at 2026-09-22T15:14Z with this card as its only item and B as the seat's recommendation (restated at 2026-09-22T16:13Z and 2026-09-22T16:31Z). The maintainer's word at this stamp names no letter and says to process the decision cards — read as the batch's single recommendation, B, the way 「19674 反正要升级,建议一步该到位」 was read as A on #19674 (5774631464). Recorded verbatim; one word from the maintainer reverses it while the card sits in pm:queue.

What is ruled — complete here, ⛔ no further decision card

Letter B. .claude/skills/pm-dispatch/SKILL.md :266 on main (815 lines) — 「派发前在飞检查:读本车道 pm:dispatched 卡认领评论申报的文件面,本地求交、不另发查询。」 — loses the word 「本车道」, so the claim-time in-flight read covers every lane's pm:dispatched claims: the declared file surfaces, exact, measured by the dev (5774791660) to fire on both founding instances ([finding] scripts/check-single-claim-paths.mjs cannot be run from an agent container — it 401s because node's fetch ignores HTTPS_PROXY, while three sibling scripts already carry the re-exec fix #18314 / [finding] scripts/check-single-claim-paths.mjs reads GitHub through node's global fetch with no proxy re-exec, so with real PR context it exits 1 on GitHub API 401 inside an agent container — the gate can be read only in CI, while its sibling post-stamped already re-execs with --use-env-proxy #18844 and finding(spec): AssembledPackageBodySchema declares callable and custom branches an inert-JSON artifact cannot hold, and every schema embedding it loses its JSON Schema #17518). Nothing else in the sentence moves; 「本地求交、不另发查询」 stays.
⛔ Not A: no stem-scan line in dispatch-runbook.md — it fires 0 / 2 on the instances that motivated the card, would spend a headroom-0 line for 29 % recall, and would have a seat write 「Serial constraints cleared」 on a probe that cannot see the case (Prime Directive chore: version packages #10, the card's own defect class). ⛔ Not C: a line stating a read and its limit closes nothing.
Re-grading. The lane's first-touch grading 5727063626 (no SKILL.md edit) is superseded for this one-word deletion; the card's Done-when (the stem scan) is retired by the measurement in 5774791660, the finding stands.
Landing. Tier S (.claude/**) at CONTRACT_REVIEW_TIER (fable), Clause-②: no, skip-changeset, one PR Fixes this card; check:pm-skill-ratchet and check:skill-line-ratchet are unmoved by a deletion inside one line (815 stays 815). Serial: behind Retire the in-seat clause-② contract review — the rule, its gate label, and the 9k-line checker's gate role #19061 step ③ (PR pm: retire the needs:contract-review label from the tree (ruling B step ③) #19737, draft, touches SKILL.md), and ordered against PM protocol: SKILL.md 819 → ≈300 lines of principle (red lines · state model · entry · index), the dispatch / review / landing detail relocated into per-phase references, and core-rules.md retired as a duplicate (maintainer direct dispatch, batch #213 item 4) #19716 (the split) and protocol(pm): cloud seats write as objectstack-fleet[bot] — export OS_FLEET_SESSION at 开轮 and name the relay in the channel text #19739 by the skills lane's own in-flight read — a one-word edit survives the split as relocation. The empty probe branch claude/issue-18964-claim-time-branch-stem-scan (0 commits at 4fba5036f) is reused or deleted by the taker.
Not measured by this ruling: the per-claim cost of reading other lanes' claims — 「本地求交」 stays local. If a lane finds the read too slow, that is a new card with numbers, ⛔ not a reason to restore the word silently.

State: needs-user-decision → pm:queue; domain:skills / priority:p3 kept; Ruled: line on the body in the same act. The dedupe words on the card stand.

Governed: .claude/** ⇒ Tier S — record + green ⇒ the seat lands it through the queue.
Clause-②: no
Thread-read: 5780497628
Ruling-ref: 5780497628 — batch #214 item 1, letter B (the maintainer's 「开始处理决策卡」 of the previous date); the card came back from the decision box to pm:queue on that ruling and was held behind PR #19737 on SKILL.md, which landed at 05:06 UTC of this date.
Serial constraints cleared: all 16 open objectstack PRs' file lists read in this act — none touches this claim's files; the fleet's pm:dispatched claims read across lanes (17 objectstack + 5 objectui, per ruling B on #18964): #18682's and #14512's claims name SKILL.md / check-clause2-carriers.mjs only in their own serial-check prose, their surfaces are packages/** (branches claude/issue-18682-predicate-relationship-traversal, claude/issue-14512-emitter-packages-only); #19777 (the director's, pm:blocked, unclaimed) will sit on references/dispatch-runbook.md / .claude/** — this claim is earlier and arbitrates; git ls-remote --heads origin read for the three card numbers: only #18964's empty probe branch exists (the step-③ branch was deleted at its merge).

Dispatch basis: a ruled execution card (B) whose only edit is one word on a line PR #19737 left in place at :266; the seat measured the line on 628e55dfa in this act. 北极星「优先级」第 3 条 read fresh in this act (objectstack non-epic p0 0 · p1 28; objectui p0 0 · p1 8): applied by this seat as label-based (seat post #7623 r15) — this card carries no tooling label; batch 3 on the maintainer's 「后续并发降到3」. Premise re-read on origin/main by the dev before editing: the sentence and its line are measured, not recalled; premise_still_valid: false is a first-class outcome.

ACCEPT — domain:skills seat 1 (session_01Wnstp2kTth7sGXfr8fXypc, seat post #7623), 2026-09-23T05:59Z — PR #19792 at head 8ead063f350d1c1ff3e22408d92370523dfbeab1 (round 0).

Checklist, read against GitHub and the fetched head on a review worktree, not the report: draft, base main, first line Fixes #18964, Clause-②: no on the claim; one single-parent commit on 2cf9db7c4; one file, +1 / −1 — .claude/skills/pm-dispatch/SKILL.md :266 loses the word 「本车道」 exactly as ruling 5780497628 (letter B) says, nothing else on the line or in the file moves (old sentence 0 hits, new sentence at :266; 815 / 819 lines, the widest-row pin untouched); references/core-rules.md correctly untouched (its 「本车道」 at :18 is the mutex-reading twin of SKILL.md :80, a different rule). A / C not taken, as ruled; the empty probe branch left for the seat to reap. Gates re-run by the seat at the head: check:pm-skill-ratchet, check:pm-skill-id-lint, check:skill-frame-sync, check:skill-frame-freshness, check:doc-authoring, check:pm-governed-prose — all 0; check-governed-merges.mjs --pr 19792 exit 3 GOVERNED Tier S (.claude/** ×1, 2 lines). The dev's 21-family derivation reconciled --ran 21 / 21 / 0. CI at this head: 26 latest-per-name check runs — 15 success, 11 skipped, 0 in progress, 0 other (the seat's read after the check-suite completion of this date); check-expected-skips.mjs --pr 19792 0 (every skipped run in the roster). Record: 5789722320 (PASS, rendered in-seat at the served tier). Report 5789694799 parses; mcp_calls 0; three REST writes through the fleet-write relay plus two pushes; no body PATCH by the dev.

Deviations recorded, none blocking: the dispatch's gate spellings (check:skill-line-ratchet, check:skill-id-lint) are check:pm-skill-ratchet / check:pm-skill-id-lint in package.json — the seat's spelling error, the right gates ran; the core-rules probe read one hit of a different sentence and the dev read it correctly; the harness asked for a model-named trailer and the dev kept the repository's model-free pair per AGENTS.md.

Landing: Tier S — the seat readies the PR and arms auto-merge (SQUASH) through the CCR routes in this act; at MERGED the card closes by Fixes, the seat takes pm:dispatched and the assignee off, confirms :266 on origin/main by content and reaps the probe branch.
