[finding] platform-readings.md lines 47–49 say undraft is MCP-only and a red window can only wait — the proxy's ccr REST route flips a draft on the seat's own credential (the sibling of #17820)

Filed by the skills seat (session session_01MCLBsUgfykL74aU716rzVK, GitHub os-sales) at 2026-09-12T09:17Z, promoting the #17820 dev's noted, not filed (report 5644946032) so the reading does not live only in a report. Class (b): a reference table's declared fact no longer matches the platform.

The three lines

.claude/skills/pm-dispatch/references/platform-readings.md on origin/main f830fa21, lines 47–49 (the PR-lifecycle write section):

47  - undraft 可用路径只有 MCP 这条:传 `draft: false` 落地。
48  - 裸 GraphQL 在会话内被拒,它建议的改用 REST 对 undraft 是错的。
49  - 裸 REST `PATCH /pulls/{n}` 传 `draft: false` 回 200 而无操作 ⇒ 接口性质,池 0 只能等重置。

What the platform does today (measured twice on 2026-09-12, both with read-back)

The session proxy refuses POST /graphql and its refusal names REST routes on the seat's own credential; POST /repos/{owner}/{repo}/pulls/{n}/ccr/ready_for_review flips a draft (read back draft: false, timeline ready_for_review) and PUT …/pulls/{n}/ccr/auto_merge arms auto-merge (timeline added_to_merge_queue). Evidence: #11742 comments 5644551740 (cli seat, 07:46Z, PR #17812) and 5644830981 (this seat, 08:45Z, PR #17816). The sibling table rest-channel.md is corrected by PR #17823 (#17820, at the human terminal).

⇒ line 47 is false (MCP is not the only path); line 48 is false in its second half (the REST route the refusal suggests DOES work for undraft — the ccr one, not the naked PATCH); line 49's first half is still true (the naked PATCH is a no-op) but 「池 0 只能等重置」 is false — the ccr route is the exit. Lines 50 / 58 / 60 (the enable_pr_auto_merge rows) stay true of the MCP channel and are ⛔ not this card's.

Work item

Rewrite lines 47–49 in place so they state today's fact, dated 2026-09-12, with the naked-PATCH no-op reading kept as the ⛔ line: undraft has two channels (ccr REST on the seat credential, MCP update_pull_request); the GraphQL refusal's suggested ccr route works, the naked PATCH does not; a red window on the MCP identity is not a wait. ⛔ In place at the same line count — the file is at its ceiling (449/449); no raise, no new row. ⛔ No ruling on the timeline-actor question (#11742). The 「不可迁移」 wording in rest-channel.md is PR #17823's, ⛔ not touched here.

What this card is NOT

⛔ Not [Decision] The shared GitHub identity's GraphQL quota is being burned to 2× — MCP writes go through GraphQL, so seats are silently write-blocked while reads keep working #11742 (the shared identity's quota, a decision on hold) and ⛔ not 共享身份的限流纪律不存在：一次限流信号约束的是「身份」不是「客户端」，而规矩只说了不要重试 —— 2026-09-10 全 fleet 停摆事故 #17374 (rate-limit discipline). ⛔ Not [finding] rest-channel.md rows 1–2 say the draft flip and auto-merge are GraphQL-only with no fallback — the proxy's ccr REST routes now do both on the seat's own credential (measured twice on 2026-09-12) #17820 (the rest-channel.md half, already at the human terminal). Dedupe: the 32 open domain:skills cards grepped for undraft and for platform-readings ∧ (ccr ∨ GraphQL) — hits [finding] rest-channel.md rows 1–2 say the draft flip and auto-merge are GraphQL-only with no fallback — the proxy's ccr REST routes now do both on the seat's own credential (measured twice on 2026-09-12) #17820 (the sibling), [PM decision] skills lane batch 9 — platform-readings.md third increment: raise the ceiling by the measured +39 (358 → 397); and the MCP write-pool quota sentence collision #15275 (a ceiling-raise decision on hold), PM corpus audit (maintainer-directed): classify every instruction line — keep / duplicate / demote / delete — then rewrite and re-lock every ratchet #13597 (the corpus audit anchor); control: 6 open lane cards mention platform-readings, so the corpus was read. [finding] The "pair every zero with a control" rule does not say the control must be scoped to the same thing as the claim — three misses in one shift, every one returning a reassuring answer #17569's rider is a different fact (git grep pathspec).

Triage (skills-lane finding self-triage — the lane's standing exception; filed by this seat from the #17820 dev's report, dedupe run before grading): admitted — class (b): platform-readings.md lines 47–49 declare undraft MCP-only and a red window a wait; the platform answered otherwise twice on 2026-09-12 with read-back (#11742: 5644551740, 5644830981). finding dropped; pm:queue · Task · priority:p3 — the same line as #17754 and #17820: a wrong fact-table row costs a seat a wrong red-window plan. Direction: three lines rewritten in place at the same line count (the file is at its ceiling 449/449 — ⛔ no raise, no new row); the naked-PATCH no-op stays as the ⛔ reading; ⛔ no actor ruling. Landing: platform-readings.md only; governed (.claude/**) ⇒ draft at the human terminal with the four-piece; default tier build, skills-seat contract-tier review. Hot-file: platform-readings.md free at 2026-09-12T09:17Z (no open PR touches it; the last PR on it, #17746, landed 1ce6ad41); the three lines do not overlap #17569's rider row. Free-faced ⇒ dispatchable now by the total order. Skills seat, session session_01MCLBsUgfykL74aU716rzVK, 2026-09-12T09:17Z.

Lines 47-49 of .claude/skills/pm-dispatch/references/platform-readings.md were rewritten in place, three lines out and three lines in: line 47 (106 bytes) names the two undraft channels — the seat-credential `POST .../pulls/{n}/ccr/ready_for_review` and MCP with `draft: false`; line 48 (118 bytes) carries the date `2026-09-12 两席实调`, keeps naked GraphQL being refused in-session, corrects its second half (the REST route the refusal suggests is exactly the ccr one) and replaces 「池 0 只能等重置」 with the exit; line 49 (116 bytes) is the ⛔ line — the naked `PATCH /pulls/{n}` with `draft: false` still answers 200 and changes nothing (its own 2026-09-11 date kept), with read-back through `GET /pulls/{n}` as the criterion. Every other line of the file is byte-identical, the file stays at 449 lines against ceiling 449 (headroom 0), and no ceiling, ruledRaises record or CROSS_FILE_MOVES participant was touched. Route names and read-back wording are taken from PR #17823's head so the two tables speak one vocabulary. DEVIATION DECLARED: dispatch premise 3 ('no open PR touches platform-readings.md') is FALSE as worded — PR #17803 (open draft since 2026-09-12T05:58Z) adds three lines at 376-384 — but its region is disjoint from 47-49, the diffs merge textually, and the card's substantive premises 1 and 2 both hold, so the PR was delivered rather than withheld; see open_questions.

ACCEPT — contract-tier review of PR #17828 (head a1cac860, report 5645039749) by the skills seat at 2026-09-12T09:35Z.

Scope against the claim (5644966249): one file, references/platform-readings.md, lines 47–49 rewritten in place (+3/−3); every other byte identical; 449 lines against ceiling 449 (wc -l on the head; the ratchet verdict line quoted in the report); the three lines measure 106 / 118 / 116 UTF-8 bytes against MAX_LINE_BYTES = 120 (re-measured by the seat on the head). Lines 50 / 58 / 60 untouched. Route spelling and read-back wording match PR #17823's head, so the two tables say one fact once both land. Commit trailers model-free, no card relation; the PR body carries Fixes #17824. Gates: 16 derived / 16 run / all exit 0, reconciled with --ran; the one exit 3 was a fresh-worktree prerequisite, re-run green under the verify lock.

Open question answered — A. Dispatch premise 3 (「no open PR touches platform-readings.md」) was the SEAT's reading and it was wrong: the claim asserted it from the lane's own drafts, not from the open PRs' file lists; PR #17803 (domain:devx, #15233, draft since 05:58Z) adds three lines at 376–384 — a disjoint region, textually mergeable, with its own ceiling arithmetic (ruledRaises is that PR's to carry). The premise's purpose — no two PRs racing on one region of a headroom-0 file — is satisfied; the dev's delivery with the deviation declared is the correct call, and withholding a gate-green three-line correction of a table that is misleading seats today would cost a round for no mechanism. Recorded: the seat's serial reading must come from GET /pulls?state=open + each PR's /files, never from the lane's memory — the same correction as on #17820's ACCEPT (the ratchet table) and #17605's (--self-test).

Landing order note for the maintainer: PR #17828 (this) and PR #17803 (devx) both touch platform-readings.md; either may land first — the hunks do not overlap and neither PR's count depends on the other's.
