skills(pm): land the ruled REST-channel prescriptions and closed-inclusive dedup (ceiling 87 → 93)

[os-justin]

Fixes #13900
Fixes #13965

Two maintainer-ruled cards, one governed-face PR (director batch 22, 2026-09-01, maintainer 「同意」), because the raised ceiling is meant to be spent once: 「提额预算一次用足」. Each card keeps its own closure criterion and its own commit.

What landed

Commit af0a8e5 — the #13900 half. On .claude/skills/pm-dispatch/references/rest-channel.md's list-cards row, the two prescriptions in the faithful form the previous dev flight measured: both refusals (⛔ do not follow the issues-list Link: rel="next"; ⛔ an enumeration whose total was never cross-checked is not a reading), the &page=N-until-a-short-page termination condition, the open_issues_count cross-check with the open-PR subtraction, the cause-unknown boundary, and the note that a keyword positive control is structurally blind to this class. Paid in place per ruling C: the red-window restatement is retired, and the pointer the ruling permits is folded into the 不可迁移 heading at zero line cost, so the red-window rule now has exactly one home. Ceiling row raised 87 → 93 in scripts/pm/check-skill-line-ratchet.mjs, with both rulings quoted verbatim beside it.

Commit b7c2e84 — the #13965 half. The dedup prescription itself now states that dedup must include closed cards, with the recency rationale (a card is at its most duplicable right after it closes) and both measured directions from 2026-08-31. Open-scoped dedup becomes an exception that has to be declared rather than the default. The state and label listing reads keep state=open untouched — 批 13 is not reopened, and the prescription says why: that convention governs state reads, and dedup is not a state read.

The rulings this PR executes — verbatim, untranslated

Ruling on #13900 (comment 5494348033, 2026-09-01T13:02:13Z), the legitimacy of the ceiling raise:

B 获授权:rest-channel.md 天花板 87 → ≤93 行,提额 PR 引用本裁决评论(棘轮自己的合法出口);两条处方按 dev 已测的忠实版落(两个拒绝 + &page=N 短页终止条件 + open_issues_count 减开放 PR 交叉核对 + 成因未知边界 + 关键词对照结构性盲区注记)

C 同批:退役 L58 对红窗常设规则的复述 —— 内容归属裁定:红窗规则由 platform-readings.md 配额段独家持有,rest-channel.md 只留指路

#13965 的查重处方修订同一 PR 落地(同批裁决,见该卡)—— 提额预算一次用足

D(23 字节残句)维持排除;⛔ 「已修」不得写成「已解释」—— 成因未知句必须保留。

Ruling on #13965 (comment 5494345834, 2026-09-01T13:02:02Z):

采第三形:把「查重必须含 closed(带时近说明)」写进查重处方本身 —— 零新增配额、零新机制;开域查重从默认降为需要说明的例外

(a) 近期闭卡补扫 / (b) state=all 时近界均不加

批 #13 不重开:状态读的 state=open 约定维持原样

Both excluded options stayed excluded: D (the 23-byte fragment) is not in this diff, and the cause-unknown sentence is present — the landed text says the prescription removes the dependency on the header, and makes no claim about whether the truncation is GitHub's own cursor or the egress proxy rewriting Link. Nothing here reads 「已修」 as 「已解释」.

Line budget — measured with the gate's own wrapLine, pinned at the landed count

	lines
rest-channel.md before	87
retired (red-window restatement + its adjacent blank)	−2
added — the two enumeration-completeness prescriptions	+5
added — the closed-inclusive dedup obligation	+3
landed	93
authorized ceiling	≤93

Net growth +6, exactly the authorized budget, spent once across both cards. The ceiling is pinned at 93 = the landed count, headroom 0, same convention as every neighbouring row — not at the authorization's upper bound. Every added line was produced by the gate's own wrapLine, so the file is at its canonical packing and no line exceeds the 120-byte budget. No re-wrap funding was used or attempted (筹行 is banned, and the file measures zero reclaimable lines in any case); the ruled raise plus the ruled retirement is the whole funding. The heading pointer cost zero lines: it fits inside the existing heading at 116 bytes.

Nothing else in the ceilings map moved — the diff touches exactly the rest-channel.md row and its comment.

Gates

Union derived by node scripts/pm/dispatch-gates.mjs --repo objectstack-ai/objectstack --commands after the final commit, at head ce400df — 20 families, 18 matched by path and 2 by change KIND (this diff edits a gate script). Every exit code captured by redirect before any pipe.

Green (exit 0): check:pm-skill-ratchet · check:pm-skill-id-lint · check:agent-test-spelling · check:bash32-floor · check:cli-command-ids · check:cross-package-test-inputs · check:doc-authoring · pnpm --filter @objectstack/lint run check:doc-formula-expressions · check:entry-guard · check:parse-guard · check:pm-governed-merges · check:pnpm-filter-targets · check:skill-frame-sync · check:watch-hint-literal · check:pm-dispatch-gates · scripts/check-ci-filter-parity.mjs · scripts/check-cross-package-test-inputs.mjs · scripts/check-shard-attestation.mjs · scripts/pm/bare-root-worklist.mjs --self-test · plus check:nul-bytes (not derived; any edit owes it) and the repo-wide pnpm lint, both exit 0 at this head.

NOT MEASURED: node scripts/check-test-completeness.mjs exits 3 with no argument — it needs a saved turbo run test log, which the local family invocation has none of. Its own words: "Nothing was measured … ⛔ It is NOT a finding." It runs in CI.

The ratchet's own verdict line at this head, quoted rather than inferred from an exit code:

✓ check-skill-line-ratchet: .claude/skills/pm-dispatch/references/rest-channel.md is 93 lines (ceiling 93; headroom 0).

origin/main was merged into the branch before this run (it had moved two commits, neither touching either file), so the union above was derived and run on the tree that is at ce400df, not on a stale one.

Governed face

.claude/** — draft PR, human merge by GOVERNED_APPROVERS, no auto-merge, not queued. skip-changeset applies: the diff is .claude/** plus scripts/pm/** and publishes nothing from any package. The published skills/ directory is untouched, so the published-skill line and token readings are not owed here.
