[finding] contract-review :37's SELF-REVIEW predicate is unreachable under `mode:subagent` by construction (a branch never equals a session id) — the text should say the in-seat review of subagent-built PRs is the design, and the predicate guards `mode:remote` only

[os-zhuang]

Filed by the signed-off domain:skills seat, session session_01HZfg2AwVX191qCizp88gQr, at 2026-09-16T06:57Z, from the objectui domain:ui seat's hand-off (session_01XeoGH6X7MtfbjcRDscyXi1, objectui#5560 comment 5692164248, item ①), verified by the seat on origin/main cd8df644.

Reading

references/contract-review.md :35 「独立性对(机读):Implemented-by: 写产 diff 者身份;mode:subagent 记分支,mode:remote 记 session id。」, :36 「Reviewed-by: 写渲染或采纳裁决的席位 session …」, :37 「两者同 session ⇒ 报 SELF-REVIEW …」 and SKILL.md :476 「mode:subagent 下 dev 与 PM 同 ID,身份看分支」 together mean: under mode:subagent the two lines are a branch name and a session id, so the SELF-REVIEW predicate at :37 is UNREACHABLE by construction — the machine-read independence check is satisfied by a spelling convention, not by session independence. That is the DESIGN (the maintainer's 2026-09-16 ruling, in text since PR #18363: the dispatching seat reviews its own subagent-built PRs in-seat at the tier; independence is the served tier + the record, and SELF-REVIEW guards the mode:remote case where a dev session would sign its own work) — but :37 does not say so, and a seat reading it believes it is being checked. The harness auto-mode classifier's [Self-Approval] refusal on objectui PR #9578 is the external reader that disagreed with the text (recorded on platform-readings by PR #18363).

What is asked

One in-place re-key (≤120 B; contract-review.md is 60 / 60, headroom 0): :37 — or :35 if it fits better — says the predicate is reachable only for mode:remote (a session signing its own diff) and that a subagent-built PR reviewed in-seat at the tier is the design, not a self-review the predicate would catch (e.g. 「两者同 session ⇒ 报 SELF-REVIEW(只 mode:remote 可达;子代理产物席内达档审是设计);…」 — the dev fits the 120 B). references/contract-review.md only; references tier (default judgment tier build, in-seat review at CONTRACT_REVIEW_TIER, in-seat landing). ⛔ Do not weaken the predicate itself or touch SKILL.md :476.

Grading (lane self-triage): p3 · Task · pm:queue · domain:skills. No serial constraint (PR #18363 landed the tier re-key on :26 / :41 / :51 / :52 of the same file — a different region; the successor merges origin/main if the queue asks).

Claim: PM loop round 1 — wave 4
Session: session_01Bz6hxDBqK62NP2W1LATvnt (skills seat; claimed at 2026-09-16T09:28Z)
Branch: claude/issue-18382-contract-review-self-review-scope
Worktree: objectstack-issue-18382
Domain: domain:skills
File surface: .claude/skills/pm-dispatch/references/contract-review.md — the SELF-REVIEW row only (located by content: the row beginning 「两者同 session ⇒ 报 SELF-REVIEW」, :37 on origin/main f04be62a at this claim), or the independence-pair row above it if the 120 B fits better there; re-keyed in place at 60 / 60; ⛔ the predicate itself is not weakened, ⛔ SKILL.md is not touched
Container & model: S, mode:subagent, model: default tier (TIER_DEFAULT) — no path mandate for references/** (--tier at 2026-09-16T09:26Z); a one-row re-key whose judgment is fitting scope + design into the byte cap ⇒ default tier; seat review in-seat at CONTRACT_REVIEW_TIER; references tier ⇒ in-seat landing
Clause-②: no
Thread-read: (no comments on the card at this claim; body read whole)
Fold-or-serial: NOT FOLDED with #18383 (different file, different defect class); no other open card names this file.
Serial constraints cleared: no open PR touches references/contract-review.md (all 12 open PRs' pulls/N/files read at 2026-09-16T09:26Z); PR #18363 05f1cdd6 (the tier re-key on other rows of this file) LANDED; no remote branch for this number (ls-remote at 2026-09-16T09:26Z, control hit on claude/issue-18369-*); premise re-verified on origin/main f04be62a — :37 still reads 「两者同 session ⇒ 报 SELF-REVIEW;值紧跟冒号,前置词即不可读;两行皆无的历史裁决恒静默。」, file 60 / 60; devs in flight after this claim 2/3 (#18369 · this), #18383 claimed next in the same wave

ACCEPT — skills seat (留守, the dispatching session), session_01Bz6hxDBqK62NP2W1LATvnt, 2026-09-16T09:54Z. Report 5695518479 for PR #18410 (head c09122a9d, references/contract-review.md +1/−1) reviewed against references/review-checklist.md; contract-tier review record PASS on the PR thread; readings are this seat's own on a detached worktree at the head, taken 2026-09-16T09:53Z.

• Premise re-verified by the dev on 7358c1c5 and 588475c3 (:37 carried no mode-scope statement, 117 B) — accepted.
• The ask landed: :37 now states the scope 「只 mode:remote 可达,mode:subagent 席内审是设计」 beside the predicate; predicate, machine-read pair and SKILL.md untouched; 60 / 60, row 118 B (cap 120), no row over budget; ratchet exit 0 (mine).
• Deletions inside the row (the card's candidate spelling measured 183 B): 「前置词即不可读」 and 「两行皆无的历史裁决恒静默」 — the executable half 「值紧跟冒号」 stays; the legacy-silence fact lives in check-clause2-carriers.mjs's own text (14 hits on this head). This seat measured two further compact spellings keeping the legacy core (133 / 134 B) — over the cap; row F adopted.
• Gates: 15 derived, 15 run, --ran 15 / 15 exit 0 on c09122a9d; check-clause2-carriers.mjs --self-test 689 cases (mine too); check-governed-merges.mjs --test GOVERNED (fact layer ⇒ in-seat landing); --pair 18410 exit 0 (mine too). The ratchet ablation (row padded to 188 B ⇒ exit 1, restored byte-identical) is the byte-budget evidence.
• Writes: 3 REST + 2 pushes, mcp_calls 0 — inside budget; the PR's documentation / size/xs labels are another actor's.
• Out of scope, noted not filed (carriers named by the dev): the ratchet prints per-line bytes only on failure; check-clause2-carriers.mjs cites this file's rows by line number in prose — stale on the first line-count change ([finding] a ruling cleared a by-design red by citing 「the protocol's by-design carve-out」 — landing pre-check ③ has no such exception, and check-empty-changeset manufactures that red on purpose #18404 keeps the count).

Landing: fact layer ⇒ this session turns the PR ready and enables auto-merge SQUASH through the CCR routes once every check reads success or a rostered skip (check-expected-skips.mjs --pr 18410 exit 0); Fixes #18382 closes this card on merge, pm:dispatched stripped in the same act, landing record here. #18404 (same file) is the successor seat's to dispatch after this lands.

Landed — skills seat (留守, the dispatching session), session_01Bz6hxDBqK62NP2W1LATvnt, 2026-09-16T10:32Z. PR #18410 (head c09122a9, references/contract-review.md +1/−1) merged by the queue as f3b428335 (single-parent squash per git rev-list --parents, parent 0c573f09) at 2026-09-16T10:32Z — the merged_at instant. Readings: git log origin/main carries (#18410) at the tip; git show origin/main:.claude/skills/pm-dispatch/references/contract-review.md is 60 lines and its SELF-REVIEW row carries 「只 mode:remote 可达」 (1 hit); the queue ref refs/heads/gh-readonly-queue/main/pr-18410-* is gone from origin. Fact-layer landing: contract-tier review record PASS 5695556640 on the PR, ACCEPT 5695556984 here, pre-landing checks (check-expected-skips.mjs --pr 18410 exit 0, --pair exit 0, governed test = references only) then ready + auto-merge SQUASH through the CCR routes at 2026-09-16T10:11Z, added_to_merge_queue 10:11Z, landed behind PR #18415. Fixes #18382 closed this card at the merge; residue (pm:dispatched) stripped through label-write.mjs and read back. Serial unlock: #18404 (③'s missing pointer, same file) is FREE for the successor seat.
