   Unblocked — pm:blocked → pm:queue, skills seat session_01Gqi43smmqjJ5sUrhfoPeKu, 2026-09-17T15:47Z. The card's own Blocked-by: #17931 is discharged: #17931 closed completed at 2026-09-17T08:06:24Z on PR #18525, squash b0eb9a59c on main, and the fourth member exists there now — packages/spec/src/automation/approval.test.ts :352 「ApprovalNodeConfigSchema — onEmptyApprovers: 'fallback' + fallbackApprovers」 read on origin/main f8eaf6704. The two carriers this card names still enumerate three (skills/objectstack-automation/SKILL.md, 961 lines, and docs/qa/platform-checklist/areas/approvals.json), so the premise 「3 of 4 once it lands」 is now the present tense. Enters the total order as p3 Task; skills/** is a governed surface, so the line budget and the tier are set at dispatch and the landing is the maintainer's.

   ACCEPT — in-seat contract-tier review of PR #18795 (head 2b1d5784e, report 5721375720) by the skills seat, 2026-09-17T21:40Z. Verified against GitHub and a scratch worktree at the head, ⛔ not against the report. Governed: skills/** ⇒ this ACCEPT is the first half of the four-piece; the maintainer's approval is the landing.

   • Scope = the claim (5721118247), one premise of the CLAIM corrected: two files, +9 / −8 in one commit — skills/objectstack-automation/SKILL.md (:728, the one enumerating row) and docs/qa/platform-checklist/areas/approvals.json (the approvals.approver-resolution-matrix item); skip-changeset decided by the repo's own Require a changeset step (pr-automation.yml :757–:780 names skills/ and docs/ as releases-nothing; 0 of 83 package.json files[] name either path, positive control 70 name dist); Clause-②: no on the PR body and the claim, check-clause2-carriers --pair 18795 0 (seat's run); check-governed-merges --test exit 3 (skills/** ×1 — one hit governs the whole PR). The seat's claim said the JSON carrier might hold no enumeration (its grep found 3 hits); the file holds 15, and the item's steps :1207, fork clause :1236 + verify :1238 and sources :1256 / :1257 DO enumerate the three members (revision 1, 2026-08-30, older than the card) — the card's premise holds for both carriers, the claim's aside did not, said here.
   • The member's meaning, read from the schema, ⛔ not the card: approval.zod.ts :884 onEmptyApprovers: z.enum(['admin_rescue', 'fail', 'auto_approve', 'fallback']).default('admin_rescue'); :906–:907 fallbackApprovers: z.array(ApprovalNodeApproverSchema).min(1).optional() 「Approvers the request opens on when onEmptyApprovers is 'fallback'」; :897–:898 required iff 'fallback' and refused otherwise, both arms enforced by checkFallbackApproversPairing (:728–:767); approval.test.ts :352; the runtime fork approval-service.ts :2782–:2836 (a fallback that resolves to nobody degrades to admin_rescue, with its own warn). The seat re-read :884 / :897–:898 / :906–:907 / test :352 on the head.
   • Carrier 1, read in the diff: :728 gains ONE parenthetical in the row's own register — 「fallback (request opens on the sibling fallbackApprovers instead — same shape as approvers, required by this policy and refused under any other; a fallback that itself resolves to nobody degrades to admin_rescue)」 — before the row's closing sentence; no other line (:635 names the key, :653 / :693 pick 'fail' — not enumerations). Token ratchet: 12511 → 12567 / 12768 (headroom 257 → 201; seat's run on the head), no ceiling raised, no ruling spent; 961 → 961 lines.
   • Carrier 2, read in the diff: steps :1207 gain the 'fallback' fork leg (opens on the fallback slate, pending_approvers holds the fallback's resolved ids, the 「opening on the declared fallbackApprovers」 warn; a fallback resolving to nobody degrades to admin_rescue with the 「resolved to nobody either」 warn — both fragments verbatim from approval-service.ts :2807 / :2821); the fork clause :1236 and its verify :1238 gain the fallback policy and the pending_approvers assertion; sources :1256 / :1257 now cite admin_rescue|fail|auto_approve|fallback and fallbackApprovers with checkFallbackApproversPairing; revision 1 → 2 with one history row (ref #18527), per the checklist's own register (README.md :287, validator :2170). The escalation variants at :825 untouched. check-platform-checklist on the head: OK — 15 areas, 264 items (seat's run). Reverse check accepted as read: reverting the revision alone reds the validator (「must equal the last history entry's revision」), restored by blob hash.
   • Gates: 24 derived, 24 run, 0 NOT-MEASURED, all exit 0 (incl. check-skills-token-ratchet + self-test, check:doc-formula-expressions after building @objectstack/lint under the verify lock, check:skill-docs 「in sync」, check:platform-checklist, check:skill-frame-sync, check:pm-governed-merges); beyond the set: pnpm lint exit 0, check-published-list-mirrors / check-platform-checklist-watchdog / check-changeset-fixed exit 0; control-byte scan clean; JSON parses — per the report. Seat-side: ratchet, validator, governed exit 3, pair 0, schema lines, 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 items (draft PR; skip-changeset read back beside the labeler's size/s and another actor's documentation, left alone; this report), mcp_calls 0; PR body written once at create, one session-URL footer, byte-identical on read-back.
   • Deviations, disclosed: main moved d9ba33df4 → e5705a8ea between the claim and the worktree — every reading re-taken on e5705a8ea (ratchet baseline unchanged); the dispatch asked for a four-line 速读 and the os-dev definition prescribes five sections — the definition won, and the seat's 终稿 below is the record.
   • Out-of-scope, noted: :728 is now 700 characters on one line (it was already the file's widest at 512); table rows are single lines by construction and no gate reads line width. Nothing to file.
   • Landing (governed): four-piece — this ACCEPT on the card, the seat's ## 维护者速读(终稿) on the PR, needs-user-decision, review requested from os-zhuang + hotlong; after an authorized APPROVED the seat strips needs-user-decision and os-zhuang enqueues (ruling C). Hot-file queue behind it on either file: none.
