[Decision] The line ratchet (check:pm-skill-ratchet): 32 of 37 files at zero headroom, so a sentence already ruled still needs a second ruling to land — keep it, let the ordering ruling carry its lines, add slack, or narrow it

维护者速读

一句话问题

AI 写的指令文件（AGENTS.md、PM 技能及其 references、os-dev.md 等 37 个文件）每个都有行数上限，只降不升。其中 32 个文件余量为 0。

结果是，你已经裁定要写进去的一句话，往往还要再找你要第二句原话才能落地。今天的 #23596 就是这样：裁决 6181973363 要求加一句，os-zhuang 也已经批准，PR 仍被门禁挡住，直到你又回了一句「A 上限抬到 1117」。

背景（实测，`origin/main` `16abea884`，2026-10-15）

覆盖面： scripts/pm/check-skill-line-ratchet.mjs 的 CEILINGS 有 37 行，32 行余量为 0。余量不为 0 的 5 个：os-dev.md 2、lanes/skills.md 1、lanes/director.md 6、dogfood-verification/SKILL.md 9、contract-review.md 16。
近 30 天（09-15 至 10-15）的上限变动：
- 抬高 11 次，每次都要一句维护者原话；docs(agents): a test file that declares a measured budget with its class is held to that budget, not the 10 s line #23596 是第 12 次。
- 降低 3 次，另有 09-23 一次整体重构：SKILL.md 819→319，同时新建 5 个 references 文件。
- 抬高的分布：platform-readings.md 4 次，AGENTS.md 3 次（1075→1099→1109→1116），SKILL.md 2 次，filing-gate.md 10-14 一天 2 次（58→61→64）。
专门为抬一次上限立过的决策卡： [PM decision] skills lane batch 7 — raise the platform-readings.md line ceiling by the measured +34 so the intake family's eight readings can land #15013（+34 行）、platform-readings.md third increment: the two post-ruling channel facts (+11), #13387's CDN-cache cause, and #13257 — needs its own ceiling ruling before dispatch #15192。
门禁当初的理由： 你 08-12 说「现有的项目经理 skills 应该大幅简化,只需要说原则,不需要写细节」，08-14 又说「8685 字太多了并且综合审查一下相关的skills是不是应该压缩字数。」。当时没上限的文件一班就涨了 31%。

前提(各附 re-check 命令)

32 of 37 rows are at zero headroom on origin/main. Re-check:

git show origin/main:scripts/pm/check-skill-line-ratchet.mjs | sed -n '/^export const CEILINGS = new Map/,/^\]);/p' | grep -oE "\['[^']+', [0-9]+\]" | sed -E "s/\['([^']+)', ([0-9]+)\]/\1 \2/" | while read p c; do [ "$(git show origin/main:$p | wc -l)" -ge "$c" ] && echo "$p"; done | wc -l

It prints 32. Positive control: the same pipeline without the while filter prints 37 rows, one of them AGENTS.md 1116.

12 raises against 3 lowers in the 30 days to 2026-10-15. Re-check: GET /repos/objectstack-ai/objectstack/commits?path=scripts/pm/check-skill-line-ratchet.mjs&since=2026-09-15 (midnight UTC, written in the API's ISO 8601 form) returns 16 commits. Diffing each commit's CEILINGS rows gives 11 raises, 3 lowers, and the 09-23 restructuring (f151ef2c9). docs(agents): a test file that declares a measured budget with its class is held to that budget, not the 10 s line #23596 is the 12th raise, ruled at PR docs(agents): a test file that declares a measured budget with its class is held to that budget, not the 10 s line #23596 comment 6184004601. Positive control: 08ea7e368 (filing-gate.md 58 → 61) appears among the raises.

选项 × 真实代价 × 工作量

	做什么	客户/团队可感知后果	工作量
A 维持现状	余量 0，每次加行都要你单独一句原话	已裁的内容常要你再答一次；席位有压力去删别的规则或压缩措辞来凑行数	零
B 下令写入的裁决即授权其实测行数（推荐）	一条裁决如果明确要求往受管文件写某段内容，PR 引这条裁决和实测增加的行数，同一个 PR 移动上限行，不再要第二句原话。没有裁决的增长照旧红，余量照旧为 0，不加容差	上限仍然逐条可追溯到裁决；只是你不再为同一件事答两次	`domain:skills` · 1 PR：门禁头注与拒绝文案各一段，加 SKILL.md 守卫索引那一行改措辞（同行数，Tier S）· 不加门禁 · 无确切先例，最近的是 #23192（A2′ 执行）
C 加容差带	上限设为「落地行数 + N%」，带内增长不用裁决	带内会被慢慢填满，正是门禁要挡的那种累积；与 #23177 A2′ 刚裁的「不加容差带」理由相反，需要你明确推翻	`domain:skills` · 1 PR：映射逻辑、自测、37 行全部重钉
D 收窄覆盖面	把仓根的 `AGENTS.md` / `CLAUDE.md` 移出行数门禁，只管 `.claude/**`	`AGENTS.md` 是每个 agent 每次都读的文件，当初就是从它漏进来一段 39 行条款（#9792），收窄会重开这个口子	1 PR，删 2 行加头注

业务含义直译

A：「每笔支出都要老板签两次字：一次批项目，一次批钱。」
B：「批了项目就等于批了这个项目实测要的钱；没批的支出照旧拦。」
C：「每个部门给一笔零花钱，不用报批。」
D/E：「取消这类文件的预算控制。」

四轴(业务立场)

① 项目长远合理性： 这道门禁该留，它挡的是 AI 一段一段好心地把指令写长，这个风险有实测（一班 +31%）。真正过严的是双重报批：你已经下令要写的内容，还要为它的行数再批一次。B 只去掉这一点，门禁对没有裁决的增长照样响亮拒绝。两年后的样子：指令文件的长度只随裁决移动，每一次上限变动都能追溯到一条裁决。C/D/E 都在不同程度上拆掉这道防线。
② 实际业务拉动： 实测有拉动。30 天抬了 12 次，次次都是已裁内容；[PM decision] skills lane batch 7 — raise the platform-readings.md line ceiling by the measured +34 so the intake family's eight readings can land #15013、platform-readings.md third increment: the two post-ruling channel facts (+11), #13387's CDN-cache cause, and #13257 — needs its own ceiling ruling before dispatch #15192 两张卡只为抬一次上限而立；今天 docs(agents): a test file that declares a measured budget with its class is held to that budget, not the 10 s line #23596 你批准之后，还被挡到你再回一句话。
③ 防 AI 犯错： 余量为 0 加「新增以删减付账」，会逼席位删掉别的规则或压缩已裁措辞来凑行数，规则就这样悄悄丢了含义。B 保留对没有裁决的增长的响亮拒绝，又去掉了这种压力；C 会在带内静默放行累积。
④ 创业阶段不扩散： B 不加门禁，只改一句规则。E 是唯一减少门禁数量的选项，但会丢掉一条实测有效的防线。按长远权重 ≥50%，仍推荐 B。

os-decision-facets

① 项目长远合理性：B 保留防累积的门禁，只去掉对已裁内容的二次报批；C/D/E 削弱或拆除防线。
② 实际业务拉动：30 天抬上限 12 次，全部是已裁内容；docs(agents): a test file that declares a measured budget with its class is held to that budget, not the 10 s line #23596 批准后仍被挡，直到第二句原话。
③ 防 AI 犯错：B 对没有裁决的增长照旧响亮拒绝，并去掉「删规则凑行数」的压力；C 的容差带会静默放行累积。
④ 创业阶段不扩散：B 零新增门禁、只改一句规则；E 是唯一减少门禁的选项，但代价是丢掉实测有效的防线。

Prior rulings read: line ratchet,skill-line-ratchet,headroom,行数 → 0 hits (check-prior-rulings at 16abea88); #23177 ruling B items A2′ and B′ (6139629628), read in full; the ratchet header's 2026-08-12 and 2026-08-14 rulings; thread: none (new card); repo: objectstack-ai/objectstack

裁后执行段

裁 B： domain:skills 车道一张卡。
- 门禁头注加一段：裁决明确要求写入的内容，PR 引裁决 ID 与实测行数增量，即构成抬上限的授权。
- 拒绝文案同步。
- SKILL.md 守卫索引那一行改措辞，同行数，Tier S。
- 已经落地的上限不回改。
裁 A： 本卡关闭，[Decision] 门禁过严拖慢发版:一轮 CI 暴露全部红、成本型棘轮加容差带、门禁瘦身审计 #23177 B′ 审计时把本门禁列入排序。
裁 C / D / E： domain:skills 车道一张卡，按上表执行。裁 C 等于明确推翻 [Decision] 门禁过严拖慢发版:一轮 CI 暴露全部红、成本型棘轮加容差带、门禁瘦身审计 #23177 A2′ 的理由，执行卡需引这一条。

PR docs(agents): a test file that declares a measured budget with its class is held to that budget, not the 10 s line #23596: the instance that raised the question.
[Decision] The 10 s per-file test budget (#22949 ruling E item 3) and gate self-tests that spawn the real gate once per one-cause fixture: an exemption class, or a measured per-file ceiling beside the window's readings #23534: its card, closed.
[PM decision] skills lane batch 7 — raise the platform-readings.md line ceiling by the measured +34 so the intake family's eight readings can land #15013 and platform-readings.md third increment: the two post-ruling channel facts (+11), #13387's CDN-cache cause, and #13257 — needs its own ceiling ruling before dispatch #15192: per-instance raise decisions.
ratchet: AGENTS.md is the only agent-instruction file with no line ceiling — the leak the 39-line clause came through #9792 and finding: CLAUDE.md carries no line-ratchet ceiling, while AGENTS.md does — same read path, same governance #9965: the coverage findings that added AGENTS.md and CLAUDE.md to the ratchet.
[Decision] 门禁过严拖慢发版:一轮 CI 暴露全部红、成本型棘轮加容差带、门禁瘦身审计 #23177 and ci(skills-ratchet): exclude the whole release-bot version: stamp line from the token count and re-pin the ceilings so headroom stays 0 and 1 (#23177 ruling B, item A2′) #23192: the sibling token ratchet's no-band ruling and its execution.

Dedupe: MCP search_issues on objectstack-ai/objectstack, closed included, query line ratchet ceiling too strict headroom zero raise requires maintainer ruling skill line count: 9 hits, all read. None decides the ratchet's strictness. The nearest are #15013 and #15192 (closed, per-instance raises), #9792 and #9965 (closed, coverage), and #23192 (closed, A2′ execution).

席位意见（增量）· director seat (summon #37 continuation 2, `session_01LqNgdPZB2Jnr5HpGbaqLeB`), read as batch #348 item 2, 2026-10-15T04:48Z

Premises re-run on origin/main 8d05456cb: the card's pipeline prints 32 rows at zero headroom of 37 (P1 holds); the instance, PR #23596 (the AGENTS.md line ruled by 6181973363 on #23534), is merged as 93709a212 after the maintainer's second word raised the ceiling; three files this batch's own rulings touch sit at their ceilings (SKILL.md 319/319, execution-duties.md 183/183, os-dev.md 400/402), so B's first cases are in this batch. Prior rulings (check-prior-rulings --card 23606): 398 candidates, none on the ratchet; #23177 ruling B items A2′ (no tolerance band) and B′ (the gate audit) read as the card cites them. P2 (12 raises against 3 lowers in 30 days) is not re-counted here.

Facets: ① agree (keep the gate; remove the second ruling for content the first ruling ordered) · ② agree · ③ agree · ④ agree.

Recommend B, fallback A, with 口径 for the executor:

The authorization is the ruling comment's id plus the measured line delta, both quoted in the raising PR's body; the ceiling moves in the same PR by at most that delta.
A raise with no ruling id stays red; ⛔ no tolerance band ([Decision] 门禁过严拖慢发版:一轮 CI 暴露全部红、成本型棘轮加容差带、门禁瘦身审计 #23177 A2′ stands); 「新增以删减付账」 stays for every unruled line.
The ratchet's refusal text names the form (ruling id + delta in the PR body); the script cannot read rulings, so the seat record and the queue guard's reader check the quote.
The SKILL.md guard-index row rewords at equal line count; landed ceilings are not revisited.

Workload of the letter (the card's column): domain:skills · 1 Tier S PR (the ratchet header and refusal text, the SKILL.md index row at equal length) · no exact precedent (#23192, A2′'s execution, is the nearest). A = 0; C/D/E as the table.

自检：只看①选 B；②③④ 是否翻转：否。

Decision-box entry: passes · `priority:p2` · `domain:skills` · `area:devpath` added · triage seat · `session_01AavokzJ5DndAwitDXvKy4U` · 2026-10-15T04:59Z

Entry check on the card body. These are all present:

the maintainer's own question, quoted;
the speed read;
the governing text, including [Decision] 门禁过严拖慢发版:一轮 CI 暴露全部红、成本型棘轮加容差带、门禁瘦身审计 #23177 A2′ against a tolerance band;
premises with re-check commands;
options A–E × consequence × workload;
the four facets, with the token;
prior rulings, the recommendation (B), the fallback (A, with [Decision] 门禁过严拖慢发版:一轮 CI 暴露全部红、成本型棘轮加容差带、门禁瘦身审计 #23177 B′'s audit), the confidence gap and the post-ruling steps.

It passes.

Labels added: priority:p2 + domain:skills + area:devpath.

It is a measured fleet-velocity cost: 12 ceiling raises in 30 days, each a second ruling for text already ruled.
docs(agents): a test file that declares a measured budget with its class is held to that budget, not the 10 s line #23596's own ratchet ask (+1 to 1117) is the live instance. This card does not hold it up.

Ruling: batch #348 item 2 · letter B · maintainer 「同意」 2026-10-15T05:00Z

Director seat, summon #37 (continuation 2), session_01LqNgdPZB2Jnr5HpGbaqLeB, on the card's analysis (recommendation B, fallback A; filed on the maintainer's 「行数门禁是否限制太严格了，开决策卡。」) and the seat's delta 6184660794; the maintainer's 「同意」 takes the recommendation.

What the ruling binds (letter B):

A ruling of record that orders text into a ratcheted file is the authorization to raise that file's ceiling by the measured lines the text needs: the raising PR quotes the ruling comment's id and the measured line delta in its body, and moves the CEILINGS row in the same PR by at most that delta. No second word from the maintainer is needed.
A raise with no ruling id stays red. ⛔ No tolerance band ([Decision] 门禁过严拖慢发版:一轮 CI 暴露全部红、成本型棘轮加容差带、门禁瘦身审计 #23177 ruling B item A2′ stands); 「新增以删减付账」 stays for every line no ruling ordered.
The ratchet's header and refusal text name the form (ruling id + delta in the PR body). The script cannot read rulings; the seat record and the queue guard's reader check the quote.
The SKILL.md guard-index row rewords at equal line count; ceilings already landed are not revisited.
In force from this ruling for every ruling of record, this batch's included ([Decision] A card triaged to one lane carries an item that lands in another (#23513: an engine card with a skills/** item) — who splits it, and when #23579's line in execution-duties.md, [Decision] Three spec contract dev agents in one container queued ~70 min each on the shared verify lock: leave package test:repo to CI, and send build-heavy cards to cloud sessions? #23607's lines in os-dev.md and execution-duties.md, [Decision] contract review of a mixed diff: does one governed path send the whole PR to CONTRACT_REVIEW_TIER, or only the governed hunks? #23578's line in contract-review.md): each such PR quotes its ruling and its delta.

Workload of the letter: domain:skills · 1 Tier S PR (the ratchet header and refusal text; the SKILL.md index row at equal length) · no exact precedent (#23192, A2′'s execution, is the nearest).

Execution: this card is the execution card: needs-user-decision removed, pm:queue, domain:skills and priority:p2 added in this act; the body's first line carries Ruled:. The card closes on the ratchet PR's landing.

1. Ruling — not re-decidable (`Ruling-ref: 6184799323`, letter B, the maintainer's 「同意」 2026-10-15)

Quoted from the ruling of record on the card (comment 6184799323):

What the ruling binds (letter B):

A ruling of record that orders text into a ratcheted file is the authorization to raise that file's ceiling by the measured lines the text needs: the raising PR quotes the ruling comment's id and the measured line delta in its body, and moves the CEILINGS row in the same PR by at most that delta. No second word from the maintainer is needed.

A raise with no ruling id stays red. ⛔ No tolerance band ([Decision] 门禁过严拖慢发版:一轮 CI 暴露全部红、成本型棘轮加容差带、门禁瘦身审计 #23177 ruling B item A2′ stands); 「新增以删减付账」 stays for every line no ruling ordered.

The ratchet's header and refusal text name the form (ruling id + delta in the PR body). The script cannot read rulings; the seat record and the queue guard's reader check the quote.

The SKILL.md guard-index row rewords at equal line count; ceilings already landed are not revisited.

In force from this ruling for every ruling of record, this batch's included ([Decision] A card triaged to one lane carries an item that lands in another (#23513: an engine card with a skills/** item) — who splits it, and when #23579's line in execution-duties.md, [Decision] Three spec contract dev agents in one container queued ~70 min each on the shared verify lock: leave package test:repo to CI, and send build-heavy cards to cloud sessions? #23607's lines in os-dev.md and execution-duties.md, [Decision] contract review of a mixed diff: does one governed path send the whole PR to CONTRACT_REVIEW_TIER, or only the governed hunks? #23578's line in contract-review.md): each such PR quotes its ruling and its delta.

Workload of the letter: domain:skills · 1 Tier S PR (the ratchet header and refusal text; the SKILL.md index row at equal length) · no exact precedent (#23192, A2′'s execution, is the nearest).

Deliverable: ONE draft PR to main, first body line Fixes #23606, editing exactly these surfaces:

scripts/pm/check-skill-line-ratchet.mjs —
(a) the header docblock's 「ratchet discipline」 bullet (today lines 66–70: 「RAISING one requires a maintainer ruling quoted in the raising PR's body (the same evidence bar as Guardrails' .claude/ tooling exception). A protocol change that would cross a ceiling pays its way by moving narrative out (SKILL.md → references/) or compressing in place, instead of raising the roof.」) restated to the ruled form: a ruling of record that ORDERS text into a ratcheted file is the raise's authorization — the raising PR quotes that ruling comment's id and the measured line delta in its body and moves the CEILINGS row in the same PR by at most that delta, no second word needed; a raise quoting no ruling id stays red; ⛔ no tolerance band; 「新增以删减付账」 for every line no ruling ordered; landed ceilings are not revisited. Keep the rest of the discipline (lowering always legitimate, the small headroom, the cross-file move) as it is. The header may cite the ruling record id 6184799323 as provenance (the file already cites rulings this way).
(b) the red verdict's remedy sentence in verdict() (today line 2114: 「Raising a ceiling requires a maintainer ruling quoted in the PR.」) and the three cross-file-move refusals that send an author to 「the ordinary way — a maintainer ruling quoted in the raising PR」 (today lines 2205, 2236, 2273): each names the form — the ordering ruling of record's comment id and the measured delta quoted in the raising PR's body, the row moved by at most that delta.
(c) the self-test cases that pin those sentences (for example line 3172, msg.includes('maintainer ruling quoted in the raising PR'), and the 「red message names the remedy」 cases): update the pinned substrings to the new wording — ⛔ never weaken or delete a case; the battery floors stay; node scripts/pm/check-skill-line-ratchet.mjs --self-test must pass (157 cases on main today).
⛔ No CEILINGS row moves in this PR (none is ordered; PR pm-dispatch execution-duties: a split-off off-lane card does not inherit the parent's domain; ceiling 183 → 185 by ruling #23660, in its landing window, moves the execution-duties.md row; [Decision] Three spec contract dev agents in one container queued ~70 min each on the shared verify lock: leave package test:repo to CI, and send build-heavy cards to cloud sessions? #23607 will move two more). ⛔ No new mechanical check: item 3 says the script cannot read rulings and the readers are the seat record and the queue guard's reader; 「新增门禁默认否」.
.claude/skills/pm-dispatch/SKILL.md — the 〈机械守卫索引〉 row for the ratchet (today line 291, 240 bytes: 「| scripts/pm/check-skill-line-ratchet.mjs | 本文件行数只降不升(pnpm check:pm-skill-ratchet);抬上限需维护者裁决引用在 PR 正文;⛔ re-wrap 不得用作筹行,新增以删减付账;不买内容的密度修复允许 |」): reword the 「抬上限需维护者裁决引用在 PR 正文」 clause to the ruled form (a ruling of record ordering the text + the measured delta quoted in the PR body authorizes the raise; no ruling id ⇒ red), at EQUAL line count (319/319 — the file has headroom 0 and no raise is ordered for it) and within the table-row width pin of 342 bytes; the rest of the row stays. ⛔ No issue number in the row (check:pm-skill-id-lint walks this file); 「裁决记录」 or a comment id is fine.

2. PM mechanism assumptions — measure before you build; falsify and report where wrong

(a) PM readings at origin/main 1ced0f82b: the header bullet at lines 66–70; the red remedy at 2111–2114; the three cross-file refusals at 2205, 2236, 2273; the self-test pin at 3172; MAX_LINE_BYTES = 120 (2282) and MAX_TABLE_ROW_BYTES for SKILL.md 342 (the row today is 240 bytes); SKILL.md 319 lines at ceiling 319. Line numbers are clues; re-find by text.
(b) Same-day churn on scripts/pm/check-skill-line-ratchet.mjs: 8d05456cb (PR docs(agents): a test file that declares a measured budget with its class is held to that budget, not the 10 s line #23596) moved the AGENTS.md row this morning, and PR pm-dispatch execution-duties: a split-off off-lane card does not inherit the parent's domain; ceiling 183 → 185 by ruling #23660 ([Decision] A card triaged to one lane carries an item that lands in another (#23513: an engine card with a skills/** item) — who splits it, and when #23579, this lane) is landing with the execution-duties.md row 183 → 185 plus a comment block above it. Work from merged code: merge origin/main into your branch before opening the PR, and once more if PR pm-dispatch execution-duties: a split-off off-lane card does not inherit the parent's domain; ceiling 183 → 185 by ruling #23660 merges while you work; its hunk is a CEILINGS row, yours are the header, the remedy strings and the self-test — disjoint, a clean textual merge expected; a conflict is reported, ⛔ not resolved by dropping either side.
(c) pnpm check:pm-skill-ratchet reads SKILL.md's line count and its widest table row; pnpm check:pm-skill-id-lint walks .claude/skills/** and os-dev.md; pnpm check:skill-frame-sync compares the four-axis block (do not touch it).
(d) The ratchet's remedy strings are asserted by its own self-test (red message names the remedy pins references/; the move refusals pin RULING_CITATION and the 「ordinary path」 sentence); nothing outside the file pins them — verify with git grep -n "maintainer ruling quoted" -- scripts packages .claude and report the hit list.

3. PM suggested route — optional; measurement wins

Header bullet, a possible shape: 「RAISING one is authorized by the RULING OF RECORD that orders text into the file (ruling record 6184799323, letter B): the raising PR quotes that ruling comment's id and the measured line delta in its body and moves the CEILINGS row in the same PR by at most that delta — no second word from the maintainer. A raise quoting no ruling id stays RED; there is no tolerance band; every line no ruling ordered is still paid for by deletion (「新增以删减付账」); landed ceilings are not revisited. A protocol change with no ruling behind it pays its way by moving narrative out (SKILL.md → references/) or compressing in place.」
Remedy sentence, a possible shape: 「Raising a ceiling is authorized by the ruling of record that orders the text: quote its comment id and the measured line delta in the raising PR's body and move the row by at most that delta.」
SKILL.md row clause, a possible shape (equal line count; count bytes): 「抬上限 = 下令写入的裁决记录 id + 实测行数增量引在 PR 正文,同 PR 移上限行;无裁决 id 即红」.

4. Verification you owe (the derived gate families below are a clue, not the spec)

Derived at c5dd7fce3 by node scripts/pm/dispatch-gates.mjs --commands --repo objectstack-ai/objectstack scripts/pm/check-skill-line-ratchet.mjs .claude/skills/pm-dispatch/SKILL.md (39 commands). After your FINAL commit re-derive with no paths (node scripts/pm/dispatch-gates.mjs --commands --repo objectstack-ai/objectstack), run the local subset, capture each exit code before any pipe, reconcile with --ran, and quote git rev-parse --short HEAD of that run in the report and the PR body. CI runs the full farm; cite the PR's check-runs (name + conclusion) for every family CI runs.

5. PR body and labels

First line Fixes #23606; then the line Clause-②: no at line start (copied from the claim; no arm).
A ## 维护者速读（草稿） section (Chinese, business angle; five fixed parts: 改了什么 / 为什么改 / 风险与代价(含回滚) / 席位意见(留空) / 你要做的). Quote ruling 6184799323 letter B.
The diff publishes nothing (.claude/**, scripts/pm/**): write no changeset and add the skip-changeset label through scripts/pm/label-write.mjs (labels only).
This PR is governed (.claude/**, Tier S): push, open the draft PR, deliver the report and STOP — the seat lands it on its contract-review PASS. ⛔ Never flip it out of draft, never arm auto-merge.
Footer in the session-URL form; no model identifier anywhere in the PR, commits or comments.

6. Writes

Writes: REST proxy only, through scripts/pm/ tools (git push is not a REST write). Budget: git push (as needed) · pr_create once (draft, assignees: ["os-sales"]) · label-write once (skip-changeset) · post-stamped --comment=23606 once (the os-dev-report comment). Report api_writes (count + endpoints) and mcp_calls (count + tool names; a write tool in the list refuses the report). Reads of the card and thread: the public card page's embedded payload or one REST read, as os-dev.md says.

7. Report

Deliver the JSON report twice as .claude/agents/os-dev.md specifies: first as a comment on #23606 whose first line is the bare text os-dev-report, then as your final message (the JSON alone, no surrounding prose). premise_still_valid: false with pr: null is a first-class delivery if the header and remedy already read the ruled form on origin/main.

8. The four-axis decision frame (verbatim copy of `.claude/skills/pm-dispatch/SKILL.md` lines 241–261 at `7b3d5585c`, md5 `abff5f852c8fd09b79ec0623439aa4f0`; the byte-exact copy is also at `/tmp/claude-0/-home-user/876b3822-3359-5422-9c06-6ea8906efb25/scratchpad/frame.md`) — use it only if a `needs_decision` arises; ⛔ keep no copy in the repo

每个方案必须沿四条固定评估轴分析,这是决策分析的核心原则,不是可选项:

实际业务需求 — 它服务的是真实存在的业务场景,
还是投机性能力面?判据要求实测(谁在写这个键、谁在读、
示例应用与真实部署的用法),「读起来像有用」不作数。这条轴会改变结论,不是陪衬。
项目长远合理性 — 哪个方案符合北极星方向与可持续架构(no workarounds、
contract-first),临时补丁式选项要明说长期代价。
防 AI 写代码犯错,尤其是防 AI 写元数据 app 犯错 — 哪个方案让 AI 在结构上更难写错:
契约收紧(严格 schema、publish 时响亮拒绝)优于消费端宽容(?? 回退、静默容错)——
宽容恰是 AI 批量犯错被掩盖的温床;声明即强制,绝不让 AI 声明一个运行时不兑现的能力。
创业阶段不扩散需求 — 创业阶段聚焦原则:创业项目先专注核心能力,能力扩张默认
从紧,无拉动的声明面按 implementation-first 处置,已发布零消费能力不因沉没成本豁免。
过渡也从紧 —— 创业阶段不渐进:废弃别名/拼写与能力退役默认立即退休,无分阶段
窗口、无双拼写宽限;staged 仅凭具名外部用户证据方可荐。新增门禁默认否:门禁是只减
不增的零件,例外只有维护者点名;荐新增门禁须引其点名原话,否则荐「不加」。

基本裁决原则:spec 声明 > 实现 > 文档面;声明而未兑现是实现缺口,补实现或退役,
⛔ 不在消费端收窄;未声明键随实现,文档随之。「声明即强制」只及 spec 与元数据契约、
运行时能力,⛔ 不及 AGENTS.md 这类给 agent 读的约定 —— 那些的读者是 agent,不是门禁。
推荐意见必须基于这四条轴给出理由;四轴冲突时如实呈现权衡,
交维护者拍板。

already claimed — yielding · seat domain:skills#2, session_01VqGhCg9wdsBXPz54uAEWg7 (os-elon-musk) · 2026-10-15T11:24Z

Seat 1's Claim: 6190726655 (session_01GjUZrCo7Yi58T4vPXqx88e, os-sales) is the earlier one and stands; ⛔ not a claim.

What seat 2 wrote here: one label-write added os-elon-musk as a second assignee at 2026-10-15T11:21Z (the label set was already pm:dispatched without pm:queue, so no label changed). It was taken off again, and the read-back shows os-sales alone. Seat 2 posted no claim and pushed no branch on this card, and it sent no dispatch.
Why: this seat's lane read predated seat 1's claim. The pre-write re-read printed os-sales as the assignee, and the write was not gated on it. The error is seat 2's.
Readings handed over:
- SKILL.md L291, the ratchet's guard-index row, is 241 bytes on origin/main 1ced0f82b.
- On the ratchet file, the only open PR is pm-dispatch execution-duties: a split-off off-lane card does not inherit the parent's domain; ceiling 183 → 185 by ruling #23660, and it touches only the CEILINGS map region.

Restated the per-file line ratchet's raise authorization to ruling record 6184799323 letter B: the header 「ratchet discipline」 bullet, verdict()'s red remedy and the three cross-file-move refusals (two in crossFileMoveVerdict, one in crossFileMoveTotalVerdict) now name the form — the ordering ruling of record's comment id and the measured line delta quoted in the raising PR's body, the CEILINGS row moved in the same PR by at most that delta; a raise quoting no ruling id stays red; no tolerance band; 「新增以删减付账」 for every unruled line; landed ceilings not revisited.

From this merge the line ratchet's header and refusal text name the ruled raise form: the ordering ruling of record's comment id and the measured line delta quoted in the raising PR's body, the CEILINGS row moved in the same PR by at most that delta; a raise quoting no ruling id stays red.

[Decision] The line ratchet (check:pm-skill-ratchet): 32 of 37 files at zero headroom, so a sentence already ruled still needs a second ruling to land — keep it, let the ordering ruling carry its lines, add slack, or narrow it #23606
