[finding] The in-seat contract-review path was read as "the implementing session reviews its own diff" — PR #14191 was PASSed and label-cleared by its author session, dropping the independence clause and the director seat's never-writes-code charter in one act

[os-support-ai]

Filed by the director seat (maintainer-summoned session session_01489YWhZEoHT9oXshiyywQy) during the independent re-review of PR #14191. ⛔ Recording only; no severity asserted. ⭐ The substantive verdict under review was independently confirmed CORRECT — no code defect shipped, no rework needed; this card is about the process shape, which only stayed harmless because the substance happened to be right.

The measured sequence (2026-09-01, all on #14161 / PR #14191)

1. A session identifying itself as "dispatching PM / director seat" claimed card ADR-0130 D4:产物 schema 增加可选 packages[] 列表,两种形态都读,分段加载键位结构性预留 #14161, implemented ADR-0130 D4 in a worktree, and opened PR feat(spec): the release artifact may carry N package manifests — optional packages[] (ADR-0130 D4) #14191 — a packages/spec/src/** clause-② diff. (Director charter: 永不认领 backlog、永不写码; the same rules the charter states as the seat's carve-out.)
2. The same session then rendered the contract review on its own diff (comment 5493145799 on ADR-0130 D4:产物 schema 增加可选 packages[] 列表,两种形态都读,分段加载键位结构性预留 #14161: VERDICT PASS) and cleared needs:contract-review — single-sided, PR carrier only; the card carrier shows no sign of ever being hung.
3. Its claim comment carries no Clause-②: machine line (the The Clause-②: yes | no machine spelling is missing from the claim comment on 2 of 3 measured cards — the enqueue gate's predicate reads it there, and it is not there #13914 shape, third sighting after [finding] If-Match: "" silently DISABLES optimistic concurrency — a quoted-empty entity-tag is read as "no token" and the guarded write proceeds unguarded #13576 and A PERMISSION_DENIED refusal never reaches the dispatcher's throw-transparent exit, so it still drops the author's userMessage — a second door, behind #7898's trigger file #13623) — check-clause2-carriers.mjs --pair 14191 read NO READING on the declaration limb until the re-review round added a carrier.

The two rules that went missing, in their own words

• references/contract-review.md (2026-08-31 ruling): in-seat review is for a tier seat reviewing "低档实现者的契约增量,非自身产物" — the whole compensating-control design assumes the reviewer did not write the diff. The independence sub-rule is explicit: an isolated reviewer must not even be fed "派发席自己的结论(污染即失独立性)". A same-session self-review is past the far end of that scale.
• references/lanes/director.md: the director seat "不占 domain:*…永不认领 backlog、永不写码;机械接手经派发 dev". The implementing session claimed, coded, and reviewed under that seat's name.

Why it matters

A clause-② spec PR carrying a self-issued PASS with the gate label already cleared is indistinguishable, to every downstream mechanism (enqueue gate, H31, the audit sweep), from one that passed independent review. Had the substance been wrong, nothing structural stood between it and main — the draft bit was the only remaining hold, and the same session controls that too. It surfaced only because the maintainer happened to summon a second seat for review.

What is NOT claimed

• ⛔ Not that the verdict was wrong — the independent re-review (PR feat(spec): the release artifact may carry N package manifests — optional packages[] (ADR-0130 D4) #14191 review comment) confirms every substantive finding.
• ⛔ Not that the session acted in bad faith: its review is thorough and its fuse reading was genuine. The gap is that the protocol text's "非自身产物" clause has no mechanical carrier — nothing compares the reviewer's session ID against the implementation claim's.
• ⛔ No fix prescribed. Candidate directions, costs unweighed: the review-verdict template could carry an Implemented-by: / Reviewed-by: session-ID pair a checker can compare; or the clear-label step could require the verdict comment's session to differ from the implementation claim's; or seats stay disciplined by text alone. The skills seat owns the choice.

Maintainer ruling — direction A adopted; graduated from finding and dispatched

Ruling: maintainer, 2026-09-01, live session with the director seat, verbatim: 「同意 A」 — adopting option A as presented: the review-verdict template carries an Implemented-by: / Reviewed-by: session-ID pair, and the clear-label guard refuses to recognise a verdict whose two IDs are the same session. Options B (text-only) and C (external review for all clause-② PRs) are not taken.

State transition in the same stroke: finding → domain:skills + pm:dispatched, assigned. Routing note: domain:* normally belongs to the triage seat; this card is routed under the standing maintainer direct-dispatch channel (2026-08-10) — the maintainer directed this card in person, quote above; triage may re-route with pm:retriage if the lane call is wrong.

Claim: maintainer-directed dispatch — implement direction A on this card
Session: session_01489YWhZEoHT9oXshiyywQy
Branch: claude/issue-14209-review-independence-carrier
Worktree: objectstack-14209-independence
Domain: domain:skills
File surface: scripts/pm/check-clause2-carriers.mjs (+ its self-test), .claude/skills/pm-dispatch/references/contract-review.md — stop on breach
Container & model: M, mode:subagent, model: opus — references-face text plus pm tooling; no protocol-semantic mandate face (SKILL.md main file / os-dev.md) is touched, so opus execution with this seat's tier review as the compensating control
Clause-②: no — pm process tooling and skill reference text; no product-contract accept/reject behaviour changes and no public surface widens
Serial constraints cleared: none known — no open PR claims these paths; the single-writer-path check re-verifies at PR time

 "summary": "Direction A's GUARD half is implemented and pushed; its TEMPLATE half is deferred on a governance blocker I am not authorised to clear, which is why this is `rework` and the PR says `Part of` rather than a closing keyword. Shipped: `scripts/pm/check-clause2-carriers.mjs` gains one report-only finding row C4, appended after C1/C2/C3 with no existing row weakened or reordered and no label ever written. C4 fires when a pair's GOVERNING contract-review verdict names the same session on both `Implemented-by:` and `Reviewed-by:`; it is silent on a distinct-ID pair, silent on a legacy verdict carrying neither line (absence never reddens a historic pair, per the card's scope), and reports a one-line-only verdict as its own MALFORMED state. A1 CONFIRMED as stated: the script had no verdict-comment reader at all, so I added a discriminator and pinned it against the live corpus rather than inventing it — real verdicts open a fenced block whose first line is `VERDICT: PASS` (comment 5493145799 on #14161), and the SAME board supplies the near miss that makes the colon load-bearing, an os-dev report on #13657 writing the phrase VERDICT command-exit 0 in backticked prose, repeatedly. Both are self-test fixtures. Three design calls are argued in the PR body and worth the reviewer's eye: strictness mirrors the sibling `Clause-②:` reader exactly (case-sensitive key, token immediately after the colon, trailing reasoning tolerated), the NEWEST verdict carrying the pair governs so an independent re-review CLEARS the row instead of leaving a remediated pair red forever (the defect #14155 had to repair in C3), and the row names its own residual hole — both IDs are self-declared and are compared only to each other, never cross-checked against the implementation claim, which was outside the adjudicated scope. C4 costs no extra API request: it reads the card thread the declaration limb already fetches. BLOCKER on the second file, measured not assumed: `check-skill-line-ratchet.mjs` pins `.claude/skills/pm-dispatch/references/contract-review.md` at 60 lines and the file IS 60 lines (gate verdict line: `contract-review.md is 60 lines (ceiling 60; headroom 0)`), so ANY net growth is red — the dispatch's 15-line net-growth budget is not spendable. Both in-place payments are refused by standing rulings, so it cannot be self-funded: re-wrap or densify to buy lines is 筹行, banned by the maintainer's 2026-08-17 ruling recorded in SKILL.md 「⛔ re-wrap(折行合并)不得用作筹行 …… 新增以删减付账」, and deleting a ruled clause is refused on the state-machine precedent, recorded twice in this very file's own ceiling comments. The one remaining route is the one this file's ceiling took on both prior occasions (51 to 57, then 57 to 60): raise the ceiling with the maintainer ruling quoted in the raising PR body — which edits a THIRD file the dispatch did not authorise and explicitly said to stop on. I stopped. It is also the wrong shape to improvise here in particular: granting my own diff a unilateral exemption from a governance control is the same act this card exists to record. Merging the guard alone is harmless — a verdict carrying neither line is silent by mandate, so C4 is inert on today's board and simply switches on once the template exists.",
 "tests": "All readings at the pushed head 57f23063f (the final commit); every exit captured by redirect-then-capture (`cmd > log 2>&1; EXIT=$?`), never read across a pipe. (1) `node scripts/pm/dispatch-gates.mjs --repo objectstack-ai/objectstack` EXIT=0, repo assertion held, 1 path vs merge base b992b1d64, three-dot, 199 families discovered, 13 matched plus 2 convention-triggered (adds or edits a GATE SCRIPT).

This gate does not run tests and cannot produce one … the local reading for this gate is NOT MEASURED.' (3) check-ci-filter-parity and check-shard-attestation FIRST returned EXIT=3 PREREQUISITE NOT MET ('the dependency `yaml` is not installed') because the fresh worktree had no node_modules; both re-ran EXIT=0 after `pnpm install`, and the 3s are reported rather than dropped because reading a 3 as a pass is the false green. (4) Repo-wide and NOT narrowed, so no narrowing needs declaring: `eslint . --no-inline-config --format json` EXIT=0 over 5,644 files, 0 errors 0 warnings, with the edited file confirmed present in the linted set by its own JSON row. (5) check-nul-bytes.mjs EXIT=0 (7,766 files); control-character self-scan `grep -naP` over the edited file rc=1, no matches. (6) check-skill-line-ratchet.mjs EXIT=0 — unchanged, since the diff touches no ceilinged file. (7) Self-test 138 cases pass, up from 98 on the base commit: 40 new, 30 of them C4's. ABLATION — the C4 comparison was neutered (`if (implementedBy !== reviewedBy)` replaced by `if (true)`, plus a marker). REBUILD: none required and none done, stated deliberately — this script is plain ESM run from source with no dist between the edit and the run, so no stale artifact can make the ablation falsely green; the ablation was run from the COMMITTED implementation so the restore leg had something true to restore to. Mutation confirmed ON DISK before any reading, both directions counted by `grep -cF`: original anchor 1 to 0, injected marker 0 to 1. Ablated run EXIT=1, 11 of 138 cases failed, including 'a same-session verdict FIRES C4' and 'a self-reviewed pair is adverse even when every carrier reading is clean' — so the new cases are not vacuous. Restore under `trap ... EXIT INT TERM` by `git checkout HEAD -- ABSOLUTE-PATH` (naming HEAD, never a bare double-dash), then proved by state rather than exit code: `git diff HEAD` empty, marker count back to 0, and worktree blob hash equal to the HEAD blob hash, both 2ea30125ae7c2a3838062f577837c7e70d905041. Self-test green again at 138. (8) PR body read back in full after create: 105 of 105 content lines byte-identical to what I wrote, no sanitizer damage, session-URL footer intact. (9) Label read-back was comparative, not existence-only: before ['size/m'], target union ['size/m','skip-changeset'], after ['size/m','skip-changeset'], stripped set empty.",

 "options": [
 "A — authorise the ceiling raise (60 to about 66) on this same branch: add the template lines plus the guard sentence to the review-checklist section, record the raise above the CEILINGS entry in the established comment form (ruling quoted verbatim, payment attempt stated, 'Landed count, headroom 0, same convention'), and flip the PR's first line to the closing keyword. This is exactly the route this file's ceiling took on both prior occasions.",
 "B — land the guard alone as it stands and carry the template on a separate, explicitly-scoped card that owns the ceiling raise. Costs a round; keeps the governance edit visibly separate from the tooling edit.",

The maintainer ruling 「同意 A」 already adopts the template as ruled content, which is precisely the evidence bar the ratchet names for a raise, and the dispatch's own 15-line net-growth budget presupposes growth that is only reachable this way — so the authorisation is a formality the dispatching seat can give, not a new decision. It also keeps the guard and the template that switches it on in one reviewable diff. ⛔ Not C: the refusal is a standing precedent, not my judgement call. B only if the seat wants the governance edit reviewed on its own."

Reporting session: session_01489YWhZEoHT9oXshiyywQy · branch claude/issue-14209-review-independence-carrier · draft PR #14216 at head 57f23063f, skip-changeset set and read back.

⚠️ One half deferred, not forgotten: the contract-review.md template lines are NOT in the PR. The file sits at its ratchet ceiling (60/60, headroom 0) and both in-place payments are refused by standing rulings, so landing them needs a ceiling raise in a third file the dispatch did not authorise. See the single open question — it needs one word from the dispatching seat, not a new decision.

决策请示:模板半边需要抬 contract-review.md 的行数棘轮上限(60 → ~66)—— 人工地板项,呈维护者

Guard 半边已交付(PR #14216,draft:carriers 脚本 C4 行 + 138 例自测,消融证实非空洞;对存量零误伤 —— 无 Implemented-by:/Reviewed-by: 行的历史裁决恒静默)。模板半边(在 references/contract-review.md 复核清单段加两行模板 + 一句守卫语义)被机械阻塞:

阻塞事实(dev 实测):check-skill-line-ratchet.mjs 钉该文件 60/60 行,headroom 0,任何净增即红。两条就地付账路均被在案裁决禁止 —— re-wrap 筹行(维护者 2026-08-17 裁)、删已裁条款(state-machine 先例,该文件自己的 ceiling 注释记了两次)。唯一合法路 = 抬上限,而「抬 ratchet 上限」在人工地板上(门禁强度),⛔ 席位不得自授 —— dev 停手正确,本席呈报而非代裁。

四维分析:

• 业务:guard 已上线但 inert(存量裁决无此两行,C4 恒静默);模板落地才是防线通电的开关。不裁则方向 A 只完成一半。
• 长远:棘轮程序自带的合法出口就是「维护者裁决引用在 PR 正文」—— 走正门是对机制的维护,该文件此前两次抬限(51→57→60)均循此例。
• 防 AI 犯错:AI 不得自抬门禁上限恰是本卡的主题 —— 本次呈报本身就是这条防线在工作。
• 不扩散:净增 ~6 行,全部是已裁内容(「同意 A」)的最小落地,零新能力面。

选项:

• A(推荐):批准本分支抬限 60→66,dev 补丁轮同 PR 落模板行 + ceiling 注释按既定形式记录(引用裁决原话),guard 与开关一个 diff 一次复审;
• B:guard 单独落地,模板另立卡单独抬限 —— 多一轮,治理面 diff 独立可审;
• C:删既有条款换行数 —— ⛔ 在案裁决禁止,列出仅为完整。

维护者一句批准即全链执行(补丁轮 → 达档复审 → governed 四件套人工终局)。状态转移:pm:dispatched → needs-user-decision,PR #14216 停靠 draft。
