finding(settings): permissions.deny omits mcp__github__update_pull_request — an MCP content write (title/body/draft) the charter now declares closed, and the seat's ready-flip fallback names the same tool #18218
Filed by the domain:skills execution seat (session session_01DAcomhvR9kKizeYgg89Vo8) from the os-dev report 5667412043 on #18205 (PR #18216), 2026-09-14T16:45Z. Bare finding — grading is the skills lane's own, deferred until PR #18216 lands (the declared side lives in it).
The gap
.claude/settings.jsonpermissions.deny (lock 1, PR #180727ef05f9973) lists 14 mcp__github__* tools and omits mcp__github__update_pull_request, which edits a PR's title and body (content) and flips its draft state through MCP — i.e. a user-to-server write under the bound account's name. PR #18216 declares at SKILL.md :98 「内容写只走 REST 代理,⛔ 无 MCP 写」 and names the tool explicitly in the ACCEPT refusal at :602; the deny list does not enforce that for the dev container.
The tension to grade
The charter also keeps MCP update_pull_request as the SEAT's fallback for the ready flip (SKILL.md :621 「MCP 兜底显式带 draft: true」; rest-channel.md :53 「备用通道 MCP update_pull_request」). Adding it to permissions.deny closes the dev-side content-write gap and removes the seat-side fallback in the same stroke; the CCR route POST …/pulls/{n}/ccr/ready_for_review is the REST-only path the seats already use. Class (b) candidate: declared (:98) vs enforced (deny list) — with the fallback line to reconcile in the same PR if the deny is added.
Not this card
#18205 / PR #18216 (the declaration), #18181 (os-dev.md :287 label write), the propagation gap (a deny entry reaches only sessions cloned after it lands — #18205 (c)).
Triage (stand-in routing for the VACANT triage seat #6015, noted on #7623; grade by the lane's self-triage): lands in domain:skills (.claude/settings.json + SKILL.md :622 + references/rest-channel.md :53); rationale: class (b) — SKILL.md :98 declares 「内容写只走 REST 代理,⛔ 无 MCP 写」 and :602 names update_pull_request in the ACCEPT refusal, while permissions.deny on b3b43b6 (14 entries) omits mcp__github__update_pull_request, and the seat-side fallback still names the tool (SKILL.md :622 「MCP 兜底显式带 draft: true」, rest-channel :53). finding dropped; pm:queue · Task · priority:p3 — a gate strengthening (one deny entry) plus two lines that route the fallback to the CCR routes the seats already use (POST …/pulls/{n}/ccr/ready_for_review, PUT …/ccr/auto_merge); ⛔ not the propagation gap (#18205 (c), landed as the harness reading). Clause-②: no. Dedupe: #18130 (the CCR route family as a facts card; rest-channel :48 / :51 already carry the two routes) is the neighbour, not a twin (control ready_for_review lit on it). Landing: rules layer (settings + SKILL.md) ⇒ four-piece and an authorized approval; build tier per --tier (SKILL.md ⇒ the contract-review tier); serial on the SKILL.md chain behind #17374 (second half) → #17497 → #18181.

ACCEPT — skills seat, session session_01HZfg2AwVX191qCizp88gQr, 2026-09-15T07:18Z. Report 5676241066 on PR #18276 (head 79ee821e) reviewed by the checklist: files changed = the claim's surface exactly (settings.json +1 · SKILL.md :622 · rest-channel :53, one line each in place); Fixes #18218 alone beside a closing keyword; skip-changeset read back; mcp_calls 0 — every write through the REST proxy or label-write.mjs; gates 17 / 17 / 0 / 0 by --ran; the seat's re-run on a detached worktree of the head all exit 0 (record 5676329091 on the PR names each). Spot readings: the deny entry sits at :55 after create_pull_request and the JSON parses; both touched lines 117 B; 812/812, 82/82; frame md5 unchanged; the --tier MANDATORY tier honoured, no exit. Deviations (8) answered one by one in the record; the two gate-name slips were the dispatch's (owned). Out-of-scope findings routed: platform-readings :43 / :46 / :47 / :338 + the second-footer reading → #18280 (behind the fold); the deny-roster gate → #18281; enable_pr_auto_merge in the deny → #18282 (the maintainer's decision, A recommended). Governed rules layer ⇒ four-piece done: record 5676329091, 速读终稿 5676329589, needs-user-decision on the PR, reviews requested from os-zhuang and hotlong at 2026-09-15T07:16Z; the card stays pm:dispatched until the landing.
Landed — skills seat, session session_01HZfg2AwVX191qCizp88gQr, 2026-09-15T15:16Z. PR #18276 (head 79ee821e) merged by the queue as 53dd5aaaafbe877a1cc72aef26511bd15c927ecf (single-parent squash per git rev-list --parents) at 2026-09-15T15:14Z — the merged_at instant, carried identically by the merged and removed_from_merge_queue timeline events. Readings at 2026-09-15T15:16Z: git log origin/main carries (#18276); the queue ref refs/heads/gh-readonly-queue/main/pr-18276-* is gone from origin; the removed_from_merge_queue event is on the timeline. Governed landing by ruling C: authorized APPROVED review 5211697198 by os-zhuang at 2026-09-15T14:54Z on that head; record 5676329091 PASS, 速读终稿 5676329589, ACCEPT 5676330010 on this card, ruling-C provenance 5682476754 on the PR; the approver flipped the PR ready and enqueued it, the seat cleared needs-user-decision and read the enqueue. Now on origin/main: .claude/settings.json denies mcp__github__update_pull_request beside the other MCP content-write tools (lock 1 complete for the PR title/body channel), SKILL.md :622 and rest-channel :53 name it. Residue (pm:dispatched, assignee) stripped through label-write.mjs and read back; PR #18285 (#18281) now takes origin/main through update-branch for its deny-roster gate, and #18280 is dispatchable once the region claim is placed.
