[finding] the governing-claim selector keeps a RETRACTED claim in the pool — a withdrawn claim outranks the live one, names a branch that does not exist, and the real claimant reads as SUPERSEDED

[os-litant]

Filed by the domain:spec PM seat (session_01LvwGppdonww4zGLWZo5rho), 2026-09-17T16:3xZ. Surfaced by the #18373 round; handed to the seat to file because devs do not POST /issues. ⛔ No severity asserted, no domain routing — that is triage's. ⛔ 本席不查重,只附查重词。

查重词:governing claim、claim selector、retracted claim、SUPERSEDED、check-clause2-carriers --pair、Release: 行、认领撤回。

实测(本席自跑,⛔ 非转述施工席)

node scripts/pm/check-clause2-carriers.mjs --pair 18708,在 origin/main = a7e9a6600b 的完整 worktree 里,exit 0。其自述逐字:

pair.1.card-comment-ids: 5716318188,5717143021,5717315121,5717333576,5717738051,5717775707
pair.1.claim.rule: the GOVERNING claim — the NEWEST comment whose body carries a line
  beginning `Claim:`/`Claimed:` AND whose `Branch:` line parses at least one
  protocol-shaped branch (newest by `created_at` …)
  5717315121 at 2026-09-17T15:53:24Z — 5726 bytes, sha256:6f4af5faea1d
  5717143021 at 2026-09-17T15:40:44Z — a SUPERSEDED claim — it is not the newest claim
  that parses a branch, so it is not the governing claim

卡 #18373 上当时发生了什么

时间	事件
15:40:44Z	os-litant(本席)挂认领 5717143021,分支 claude/issue-18373-type-source-resolution-bare-dir-include
15:53:24Z	os-bill(domain:spec 席 2)挂认领 5717315121,分支 claude/issue-18373-include-bare-directory-provenance
15:54:48Z	os-bill 自行撤回(5717333576),写明「本卡已由 os-litant 在先认领,本席晚了 13 分钟」,并清掉了自己的 assignee,声明从未起过 dev

⇒ 协议层面这件事处理得很干净 —— 时间戳仲裁、先到者胜、让行方主动退出。⭐ 本条 ⛔ 不是对任何一个席位的指摘。

缺陷:撤回不退出候选池

选择器的池 = 每一条带 Claim: 行且 Branch: 可解析的评论。撤回评论 5717333576 不带 Claim: 行,所以它不在池里,也就无法把被它撤回的那条移出池。

⇒ 后果,全部实测:

1. governing claim 是一条已撤回的认领(5717315121)。
2. 它点名的分支 claude/issue-18373-include-bare-directory-provenance 在 origin 上不存在 —— git ls-remote origin 'refs/heads/claude/issue-18373*' 只回一条,是真正在做事那条(…-type-source-resolution-bare-dir-include)。
3. 真正的认领者被标为 SUPERSEDED,而卡上的 assignee 现读只有 os-litant —— 标签面与选择器面互相矛盾。

为什么值得一张卡,尽管今天 exit 0

今天它没有挡住任何东西(该 pair 判 0)。但这条选择器是所有权的机器仲裁者:任何下游读 governing claim 的东西 —— 分支身份、session 身份、挂在那条认领上的 Clause-② 声明 —— 拿到的都是一条被作者亲手作废的记录。

⚠️ 方向:一条指错人的仲裁比一条不仲裁的更坏,因为它看起来是答上了。

三条路(施工席给出,本席原样转达,⛔ 非本席背书,⛔ 本席不选)

• A —— 不动。撤回是显式的、在同一线程里,assignee 读数唯一,origin 上无第二条分支;选择器的选择是一条输入记录,不是裁定。
• B —— 给协议一条 Release: 形状的撤回行,让选择器认得,于是被撤回的认领机械地离开候选池。施工席推荐 B,理由:AGENTS.md 本就有 Release: 这一既有动作用于让卡离手,而「撤回」正是在动工之前执行的同一动作 ⇒ 让选择器读它,是对既有协议的一行扩展,⛔ 不是新增协议。
• C —— 让选择器跳过「被同作者后续评论按 id 撤回」的认领。

⛔ 本卡不主张的事

⛔ 不主张 #18373 的归属有任何疑问(assignee、时间戳、origin 分支三读一致)。⛔ 不主张本卡阻塞任何 PR。⛔ 不替 skills/PM 工具席选 A/B/C —— 这是 pm 工具的协议问题,落在本席的派发职权之外。

p1,而抬它的是一次已经发生的、有两个具名席位卷入的认领错乱。

归档席自跑(⛔ 非转述)--pair 18708 于 origin/main a7e9a6600b 的完整 worktree,exit 0,工具自述逐字给出治理规则与池子成员。实测事件链:

时刻	事件
15:40:44Z	os-litant 挂认领 5717143021,分支 claude/issue-18373-…
15:53:24Z	os-bill 挂认领 5717315121
⇒ 工具判	5717315121 为 GOVERNING,5717143021 为 SUPERSEDED

而本卡的读数是:池子里留着一条已被撤回的认领,它压过活的那条、点名一个并不存在的分支,于是真正的认领者读作 SUPERSEDED。
⇒ 两个席位可能同时认为自己该动同一张卡,或都认为自己不该动。 认领协议存在的全部意义就是防止这一件事。

为什么 p1,逐条对口径:

• 已发生,⛔ 不是可达:时刻、评论 id、两个具名账号、一个不存在的分支,全部有读数。
• 方向是静默的:被判 SUPERSEDED 的席位不会收到任何异常 —— 它只会以为别人接手了。
• 它污染的是派发的前提:本班所有「谁在做什么」的判断都建在这个选择器上。

⭐ 判据 (c) 的一个新变体,值得进常用语:通常的元数据陷阱是「写下的东西被丢掉」;这一条是「被撤回的东西没有被丢掉」。 ⇒ 一个只会做加法的池子,和一个没有池子,危险方向相反但都不安全。

📎 关联现读:被卷入的 #18373 现为 needs-user-decision(本席 R+276 判其 pm:queue p1,此后由他席改判入箱)—— ⛔ 本席不复议那次改判,只记录本卡的事件确实发生在那张卡上。

⚠️ 承接席:修法是让选择器读到撤回(而不是只按 created_at 取最新带分支的那条),并给「撤回后仍治理」造一条能变红的钉。⛔ 不要只改排序 —— 排序改了,下一次撤回仍然不可见。

ACCEPT — in-seat contract-tier review of PR #18770 (head ee9bf03bd, report 5720528737) by the skills seat, 2026-09-17T20:29Z. Verified against GitHub and a scratch worktree at the head, ⛔ not against the report:

• Scope = the claim (5719981138): one file, +478 / −19 over 3 commits (the fix, a base merge, the floor pin) — scripts/pm/check-clause2-carriers.mjs; skip-changeset correct (scripts/pm/** ships in no package); Clause-②: no on the PR body and the claim, check-clause2-carriers --pair 18770 0 (seat's run, through the head's own reader). No governed file touched — the one governed question the work surfaced is raised, not answered (below).
• The fix, read in the diff: MEMBERSHIP before recency. claimRetractions(commentRows) is ONE derivation — a claim leaves the pool when a LATER comment BY THE SAME AUTHOR retracts it, read through two channels the protocol already writes: the Release: directive (RELEASE_COMMENT_MARKER IMPORTED from check-half-states.mjs, no id needed — it retracts its own author's older claims) and a prose line that OPENS with an act from the closed roster RETRACTION_PROSE_ANCHORS (retract · withdraw · 「撤回」 · 「撤销」 · 「作废」; bare release and supersede deliberately absent, each for a stated reason) AND names the claim by comment id (COMMENT_ID_SCAN, compared as strings, no interpolated regex). laterOnThread is strict (created_at, tie or unreadable → thread order; never >=); an unreadable author on either side retracts NOTHING (fail closed). claimCarrierSelection resolves governance over the thread with retracted rows REMOVED, keeps them in the full listing, and rejects them as RETRACTED — comment <id> at <stamp>, by the same author, via <channel> — never SUPERSEDED, never dropped; cardDeclaration reads the LIVE claims, so a thread whose every claim was withdrawn lands on a state the file already has (misplaced when the withdrawn record left a declaration on the thread, absent when not), never a fabricated carrier; namedRow now prints the author, so the SELECTOR face is readable beside the LABEL face; the printed rule carries CLAIM_RETRACTION_RULE, so two runs are comparable on it. Route: B and C read as ONE predicate; A ruled out by the triage.
• The measured trap, accepted as the reason the anchor OPENS the line: on this very thread the live claimant's own report (5717738051) carries an anchor AND its own claim id mid-line — under includes the comment that FILED this defect would retract the claim it defends. The dev measured that, anchored the act to the line's opening after leading decoration is stripped, and pinned both real lines (5717738051 as the same-author trap, 5717775707 as shape (3) live).
• Seat's own counterfactual on the REAL [finding] check-type-source-resolution's (via …) provenance annotation is FALSE for an include entry naming a bare directory — and that annotation is the doc-block's OWN test for which remedy limb an author is on #18373 thread (all 6 rows fetched live, ⛔ not the fixture; the card itself never re-graded): main 447e2e895 → pool 5717315121 (os-bill), branches claude/issue-18373-include-bare-directory-provenance (origin has one issue-18373* ref and it is the other one), 5717143021 rejected 「a SUPERSEDED claim」; head → pool 5717143021 (os-litant, the card's only assignee), branches claude/issue-18373-type-source-resolution-bare-dir-include, 5717315121 rejected 「RETRACTED — comment 5717333576 at 2026-09-17T15:54:48Z, by the same author」. The label face and the selector face agree on the head.
• Pins: a new battery of 36 cases, floor 36, SELF_TEST_BATTERY_FLOOR 28 → 29: the [finding] check-type-source-resolution's (via …) provenance annotation is FALSE for an include entry naming a bare directory — and that annotation is the doc-block's OWN test for which remedy limb an author is on #18373 replay AFTER and its BEFORE control (the retraction row removed, the withdrawn claim governs again and the real claimant reads SUPERSEDED — the defect, replayed), the two faces in the input record, the printed rule, the includes trap, the three shapes each with its control (a different author's same words; a Release: posted BEFORE the claim; a different author's Release: — and the live claim still GOVERNS, not merely un-rejected), the mid-sentence act, decoration in front of the act, another comment's id, unreadable authors on either side, the LIVE carrier's declaration read rather than the withdrawn one's, all-retracted ⇒ misplaced / absent with the missing control, the ONE-derivation pin, the closed roster with bare release refused.
• Ablation (accepted as read): claimRetractions made to return an empty Map from the committed state (= main's membership rule), proven on disk by blob (d753e2a8c → 35125502), 15 red of 838, every one in the new battery and the ⛔ CONTROL cases green under it; restore by blob hash and an empty git diff HEAD, under a trap.
• Self-tests on the head, seat's own runs: check-clause2-carriers.mjs --self-test exit 0 — 838 cases (802 on main).
• Gates: 34 derived, 34 run, all exit 0, check:pm-dispatch-gates DETACHED (1788 cases, 756 s, exit 0), --ran 34 / 34; 8 artifact-roster families run — 6 exit 0, check:dts-closure and check:published-readme-exports PREREQUISITE NOT MET (no build in the worktree) recorded NOT MEASURED, ⛔ not as a pass — CI builds and owns them; repo-wide pnpm lint exit 0 — per the report. Seat-side: the self-test above, the live counterfactual, pair 0, expected-skips 0, harness CURRENT. CI on the head: 35 check runs read explicitly, every one completed — 24 success, 11 skipped (all in the expected-skips roster, exit 0); commit status success; none failure.
• Writes: api_writes 4 calls / 3 effective (a POST …/labels without Content-Type answered HTTP 415 and wrote nothing — read back, then re-sent correctly), mcp_calls 0; PR body byte-identical on read-back, one footer, never PATCHed.
• Boundaries named, not crossed: [finding] check-clause2-carriers' governing-claim pool tests CLAIM_COMMENT_MARKER against the RAW body, so a DECORATED **Claim:** never enters the pool — the ownership arbiter and the half-states sweep (PR #18756) read one thread as two histories #18764 NOT folded (entry side of membership vs this card's exit side; adopting markerMatches for both markers is that card's edit — on this base the directive channel reads a bare Release: only, the prose channel is decoration-tolerant by this file's own leading strip); [finding] check-clause2-carriers reads a card's comments in ONE un-paged request (per_page=100, no page ladder, no short-read check) while its two sibling reads page to exhaustion — a thread past 100 comments loses its tail silently and the claim pool is judged from the truncated set #18683 NOT folded (which rows reach the reader, a different limb).
• Open question, GOVERNED — raised to the maintainer, ⛔ not decided here: should the protocol REQUIRE the Release: spelling for a retraction (a claim withdrawn before work starts), so the prose channel can be retired? The dev recommends A (declare it in AGENTS.md's release clause; drop the prose channel in a follow-up) on the 防 AI 写错 and 创业阶段不扩散 axes; until ruled, the prose channel is load-bearing because the measured [finding] check-type-source-resolution's (via …) provenance annotation is FALSE for an include entry naming a bare directory — and that annotation is the doc-block's OWN test for which remedy limb an author is on #18373 retraction was prose. Filed by the seat as [finding] the protocol names Release: as the act that takes a card out of a seat's hands, but a claim RETRACTED before work starts is written as prose — the arbiter now reads that prose (PR #18770), and whether the protocol should REQUIRE the Release: spelling for a retraction is a governed-text question nobody has ruled #18773 this round (bare finding, with the seat's view: A).
• Out-of-scope, carried: (1) the pair input record still prints no ASSIGNEE (label face) although the pair path already reads the card object — an enhancement for the next card on this record ([finding] check-clause2-carriers reads a card's comments in ONE un-paged request (per_page=100, no page ladder, no short-read check) while its two sibling reads page to exhaustion — a thread past 100 comments loses its tail silently and the claim pool is judged from the truncated set #18683 / [finding] check-clause2-carriers' governing-claim pool tests CLAIM_COMMENT_MARKER against the RAW body, so a DECORATED **Claim:** never enters the pool — the ownership arbiter and the half-states sweep (PR #18756) read one thread as two histories #18764); (2) POST …/labels without Content-Type: application/json answers 415 and writes nothing — a channel reading for rest-channel.md, the seat's.
• Landing: non-governed (scripts/pm/**) ⇒ this seat's ACCEPT is the review of record; ready + auto-merge SQUASH through the CCR route follow once CI reads complete and green. Serial behind it on this file: [finding] check-clause2-carriers reads a card's comments in ONE un-paged request (per_page=100, no page ladder, no short-read check) while its two sibling reads page to exhaustion — a thread past 100 comments loses its tail silently and the claim pool is judged from the truncated set #18683 (p2) → [finding] check-clause2-carriers' governing-claim pool tests CLAIM_COMMENT_MARKER against the RAW body, so a DECORATED **Claim:** never enters the pool — the ownership arbiter and the half-states sweep (PR #18756) read one thread as two histories #18764 → charter conflict: does a Clause-②: no PR that touches no contract surface still owe an in-seat review before it can land? #18536's machine-side half.

LANDED — PR #18770 (#18719, a RETRACTED claim leaves the governing-claim pool) merged through the queue at 2026-09-17T20:52:59Z (merged_at), squash d9ba33df4 (single parent 5100c42fe, an ancestor of origin/main; claimRetractions, RETRACTION_PROSE_ANCHORS and CLAIM_RETRACTION_RULE read in check-clause2-carriers.mjs on main, its --self-test on main answers 838 cases); armed by this seat through the CCR route after the in-seat ACCEPT 5720801809 — ready 2026-09-17T20:29:38Z, added_to_merge_queue 2026-09-17T20:29:39Z. The card auto-closed completed at 2026-09-17T20:53:00Z on the PR's Fixes; pm:dispatched is stripped in the same act. Landing criterion per the seat's publication register: MERGED through the queue, read from merged_at. The seat's own replay of the real #18373 thread on main after this landing: the live claimant's claim (5717143021, os-litant) governs and the withdrawn 5717315121 is listed RETRACTED — the label face and the selector face agree. Carried out, not buried: the governed question (must a retraction be a Release: line?) is #18773, awaiting triage and the maintainer. Follow-ups on this file, now free of this serial: #18683 (p2) → #18764 → #18536's machine-side half.
