[finding] the `skip-changeset` label suppresses the DELIBERATE-CORRECTION refusal whose own text says 「no label and no diff shape makes that safe」 — declared contract against enforced behaviour

[os-warren]

Filed by the domain:spec execution seat (#6017), session_01KB5PFtxuy1x3dcR5gxudx6, 2026-09-16T05:2xZ, from an os-dev round's out_of_scope_findings. ⛔ Not claimed, ⛔ not dispatched. Grading is triage's. ⛔ This seat did not run a dedupe search (per 「立卡者不查重,只附查重词」).

Measured by the #17396 round (report 5692289800) and independently re-measured by this seat on origin/main before filing.

The declared contract

scripts/check-empty-changeset.mjs:600-606, verbatim:

For the DELIBERATE CORRECTION class there is no second command to run … no label and no diff shape makes that safe. Correcting a pending release note is a decision about a release rather than a refactor — say so on the PR, naming the note and what changed under it, and get it confirmed. That is the existing human path; this gate stays red either way, and staying red is what puts the decision in front of a person instead of routing around it.

The enforced behaviour

.github/workflows/pr-automation.yml:850-854 — the step 「Reject an empty-frontmatter changeset added by this PR」 runs that script, and its only guard is:

if: >-
  steps.labels.outputs.skip != 'true'
  && steps.labels_settled.outputs.skip != 'true'

⇒ the skip-changeset label suppresses the entire step, foreign-changeset refusal included. A label does make it go away.

The controlled zero

⛔ Not a bare zero. Control leg: skip-changeset occurs 22 times in scripts/check-empty-changeset.mjs and steps.labels.outputs.skip occurs 13 times in pr-automation.yml ⇒ a label/exemption mechanism is discoverable by this search where one exists. Zero leg: FOREIGN_ALLOW|FOREIGN_EXEMPT|FOREIGN_CONFIRM|confirmLabel returns 0; scanForeign() (:443-473) takes a git diff and nothing else — no label, env var, allowlist or marker parameter of any kind.

Why the workflow's own defence does not cover this rule

The workflow records the open cell only for the EMPTY-changeset rule, and argues it is 「empty of motive anyway: an author who already has the label gains nothing by adding the file」. For the FOREIGN rule the motive is not empty. PR #18198 has been blocked on this refusal for over a day; the label is one write away, and nothing mechanical stops it.

⚠️ Applying it there would also be a false declaration — that PR ships .changeset/scheduled-work-deployment-switch.md declaring real package bumps — which is why the #17396 round measured the route and ⛔ did not take it.

Carrier

Whoever confirms PR #18198's deliberate correction is the first person standing in front of that incentive.

Dedupe words

skip-changeset label · check-empty-changeset foreign rule · #17712 refusal · pr-automation label exemption · 「no label makes that safe」

判据 (b):已声明契约被量为假,而且两侧都能逐字读到。

前提现读复核(2026-09-17T14:43:00Z,读 origin/main):.github/workflows/pr-automation.yml 上 steps.labels_settled.outputs.skip != 'true' 仍在 5 处 step 上,含该 DELIBERATE-CORRECTION 步。⇒ 仍活着。

契约(check-empty-changeset.mjs:600–606):「… no label and no diff shape makes that safe … this gate stays red either way, and staying red is what puts the decision in front of a person instead of routing around it.」
实行:唯一守卫就是一个标签。⇒ 门禁自述「无法被标签绕过」,而它恰恰只被一个标签守着。

为什么 p2,⛔ 不是 p1。 削弱本身是量到的、活的;但没有量到任何一次真的用 skip-changeset 绕过了一次 deliberate correction。⇒ 有实测盲区、无实测事故链 ⇒ p2。
⭐ 给一个可检验的升级条件,⛔ 不留模糊:若谁找出一个已合入的 PR,它带 skip-changeset 且其 changeset 属 DELIBERATE-CORRECTION 类,本卡即升 p1 —— 那时它就不再是盲区,是事故。

✅ 不触人类底线:把这一步从 skip-changeset 的豁免名单里拿掉是加强既有门禁,⛔ 非削弱、⛔ 非新增 ⇒ 不升维护者。
⚠️ 承接席注意:另外 4 处同守卫的 step 不在本卡范围内 —— 它们各自的脚本是否也自述「不可绕过」要逐条读,⛔ 不要顺手一起改。

L1 job-level: changeset-check carries if: !contains(github.event.pull_request.labels.*.name,'skip-changeset') and no needs:, so a payload label skips all 15 steps. L2 step-level: the step that hosts the refusal is guarded by both live label reads. L3, named by nobody so far and the one that fires FIRST on this card's own class: the job contains zero status functions, so every step inherits the implicit success(); on a PR that only corrects a foreign changeset, 'Require a changeset (or the skip-changeset label)' fails first and the refusal step is SKIPPED, so the two-class remedy text never prints — and that failing step's own message prescribes applying skip-changeset, marked PREFERRED. The clause measured false is 'this gate stays red either way', not the 'no label makes that safe' sentence, which is a normative claim about the author's act. No remedy exists inside the declared file surface: the checker has ZERO live label reads (all 22 occurrences are comments, report prose or self-test regexes over the workflow YAML), and the checker's OWN consumer battery pins the suppression in place (chunks.length === 5 plus unguarded/halfGuarded === 0 require every failable step to honour both label reads; strayScans === 0 forbids hosting the real scan in label-immune lint.yml). Fix surface is .github/workflows/pr-automation.yml, outside the fence: stopped per 'Stop on breach and explain'.

The remaining 29 of the 31 are NOT MEASURED, reason: this branch has zero commits against origin/main, so those commands grade the tree rather than a change — dispatch-gates itself refused the no-path derivation with 'this branch changes nothing against origin/main (merge base 625db0e85) — nothing to derive'. No verify-lock slot taken: nothing built or tested.",

LEG 2 empirical CI on PR #18765 (head aefbf59275282b9f277832d9f98fd67f058fc238, unchanged across all readings): runs 35265359525 (19:31Z) and 35266458091 (19:42Z) both show step 11 'Require a changeset (or the skip-changeset label)' = failure and step 12 'Reject an empty-frontmatter changeset added by this PR' = SKIPPED, i.e. the refusal never ran even with no label present; hotlong applied skip-changeset at 2026-09-18T05:38:18Z (timeline event) and run 35311587778 three seconds later reports job Check Changeset conclusion=skipped, all 15 steps gone. CONTROL for the step-order leg: PR #18889 run 35313361879, step 11 success gives step 12 success — so the skip on #18765 is attributable to the failure, not to the step. SECOND CONTROL for the label leg: run 35313016106, the settling read found a label and steps 11-15 all skipped. LEG 3 local positive control, no repo mutation, ran the SHIPPED export against real temp git repos: scanForeign() on a base commit carrying .changeset/client-get-session-envelope-and-refresh-read.md and a head that rewrites it returns [{file, status M}] gives REFUSED by the checker; negative leg, a PR adding its own changeset, returns [] gives not refused.

Exactly one hit: PR #18765, non-draft, modifying .changeset/client-get-session-envelope-and-refresh-read.md. My reading: NOT material by volume, and the one hit is the intended target — that PR's own body already declares itself the DELIBERATE CORRECTION class and quotes the gate's 'stays red either way' text. Two facts that shrink it further: Check Changeset is NOT one of the seven registered required contexts (scripts/check-required-contexts.mjs lists Lint & Repo Gates, TypeScript Type Check, Test Core, Dogfood Regression Gate, Build Core, Temporal Conformance (live PG + MySQL), Governed Surface Queue Guard), so the red flags rather than blocks the queue; and the triage seat's own p1 escalation condition is NOT met — of the 300 most recently updated closed PRs (window back to 2026-09-15T04:51:44Z), 193 were merged carrying skip-changeset and 0 of those modified or deleted a foreign changeset.

      "options": [
        "A — un-exempt step inside changeset-check. Measurably insufficient: L1 still skips the job, L3 still eats the step. Also needs a rule-selection CLI mode on the checker (the CLI always runs both scans today) and a carve-out in the consumer battery.",
        "B — a NEW job in pr-automation.yml with no label read, running the foreign rule only. Closes L1 and L2, and L3 for free since it is alone in its job. Costs: a second copy of the #6129 merge-base derivation, a new advisory check-run context, registration in the workflow-roster gates, and +19 gate families (50 commands vs 31, measured).",
        "C — drop the job-level payload short-circuit so the step-level guards become authoritative, then run the foreign rule in a step that honours neither label read and carries a status-function condition so a failing sibling step cannot skip it. Closes all three layers with no duplicated merge-base machinery. Costs: one runner per labelled PR (12 of 25 open PRs carry the label today), which is the #5580 cost argument the short-circuit exists for; plus the checker's rule-selection mode and the consumer battery moving from 5 failable steps to 6 with a documented carve-out."

      "recommendation": "C. It is the only route that closes all three measured layers, and it makes the checker's existing consumer battery TRUE rather than partly decorative: that battery already asserts every failable step honours both label reads, as if step-level guards were the authority, while the job-level payload read silently overrides them. B is the fallback if the runner cost is judged unacceptable. A should be recorded as measured-insufficient so nobody re-derives it."

维护者速读

这道门禁有一条拒绝规则:当一个 PR 去改别人的、还没发布的 changeset 说明时,拒了它,并且规则自己的文字写着「没有任何标签、任何 diff 形状能让这件事变安全」。卡面说 skip-changeset 这个标签把这条拒绝压住了 —— 这句是真的,而且比卡面写的更糟:压制有三层,没有一层在卡面点的那个文件里。

派去的 dev 没写一行代码就停了,这是对的:真正要改的是 .github/workflows/pr-automation.yml,在我给它划的围栏之外,它按「越界就停手」停了手并交回了完整证据。

⚠️ 中间出了一件我必须让你先看到的事:PR #18765 恰好就是这条规则要拦的那一类,它在 06:04 合进了 main,而拒绝从未打印。标签是 hotlong 在 05:38 亲手打上去的 —— 比我认领这张卡早 12 分钟。而门禁自己的文字说,这一类的正确做法是「在 PR 上说明、点名那条说明和改了什么、然后取得确认」。

所以问题不是技术选型,而是:打上 skip-changeset 这个动作,算不算那个「确认」?

• 如果算 —— 那把压制关掉,就是拆掉一个人刚刚用过的确认通道,补救就欠一个替代的确认动作。
• 如果不算 —— 那 fix(changeset): date the pending client entry's closing register — all three 'not addressed here' clauses had been answered #18765 的标签是误用,它的确认应当以文字形式补记。

两个问题都需要你拍板:①走哪条路(A / B / C),②那个确认动作是什么(A / B / C)。我的推荐是 ① C,② A,理由在下面。

---

四棱分析

实际业务需求 —— 拉动是实测的,而且刚刚发生。不是投机面:#18765 是本仓真实的一次「改别人待发布说明」的 PR,作者(os-support-ai)在正文里自己声明了这一类并引了门禁的原话,审批账户 hotlong 对它动了手,然后它合进了 main。⇒ 这条规则守的是真实场景,且守空了一次。⛔ 但同样实测的是:今天的爆炸半径是 0 —— 我 06:12Z 重量:23 个开放 PR,11 个带 skip-changeset,0 个碰别人的 changeset。⇒ 修它不会立刻红任何人。

项目长远合理性 —— 现状是 declared ≠ enforced 的教科书形态,而且是最坏的那种:声明写在门禁打给作者看的拒绝文字里,而同一道门禁的另一个步骤印的处方是「打 skip-changeset 标签」并标注为 PREFERRED。⇒ 门禁一边告诉作者「没有标签能让这安全」,一边推荐那个标签。这不是补丁能盖的,是结构矛盾。⛔ 另一条长远读数:dev 量到那个 checker 自己的消费者自测把压制钉死了(断言每个可失败步骤都读两个标签),所以自测今天在替一个错误行为守门 —— 补救必须同 PR 动它,否则 lint.yml 里那份无豁免的自测会红。

防 AI 写代码犯错(尤其元数据) —— 本轴权重最高,方向明确指向收紧。这是 AI 作者会批量踩的坑的纯形态:一个 agent 想让 CI 变绿,门禁印给它的处方就是打那个标签,打了之后另一条规则静默消失。⇒ 宽容端(标签豁免)恰是批量犯错被掩盖的温床;声明即强制的一侧是把拒绝变成真的拒绝。⛔ 反方向唯一的合理关切不是「别收紧」,而是「收紧后人怎么表达刻意修正」—— 那正是问题②,所以它必须与①一起答,不能分开答。

创业阶段不扩散需求 —— 本轴反对路线 B,支持 C。 B 要新开一个 job、复制一份 #6129 的 merge-base 推导、新增一个 advisory check-run context、在 workflow-roster 门禁里登记,并把门禁族从 31 涨到 50(dev 实测)。⇒ 那是为一条已有规则铺第二套机械。C 不复制任何机械,代价是每个带标签的 PR 多跑一个 runner(今天 11/23)。⛔ 按不扩散原则,C 的代价是算力、B 的代价是面积,创业阶段宁付算力不付面积。

四棱结论:同向指向 C(问题①)。 分歧只在问题②,所以它单独呈报。

Governing text

• scripts/check-empty-changeset.mjs:602-604,逐字(我 06:10Z 自读):「…no label and no diff shape makes that safe. Correcting a pending release note is a decision about a release rather than a refactor -- say so on the PR, naming the note and what changed under it, and get it confirmed. That is the existing human path;」
• scripts/check-empty-changeset.mjs:535:「The remedy for the DELIBERATE-CORRECTION class (fix(scripts): the foreign-changeset refusal prescribes restoring a release note the same PR made false — name the second class (ruling D on #17712) #18160, ruling D on finding: random changeset filenames collide silently across parallel agents — a round overwrote a sibling PR's minor changeset and every gate stayed green #17712).」
• ⭐ 注意 governing text 自己规定的人工通道是「在 PR 上写明 + 取得确认」,不是打标签。问题②正是问这两者今天是否被当成了同一件事。

证据 —— 哪些是我自核的

dev 的报告我逐条对 GitHub 核过,⛔ 不采信自述。我自核并命中的:

断言	我的读数(06:10Z–06:12Z)
L3:changeset-check 内零状态函数	✅ pr-automation.yml 第 243–1033 行 always()/failure()/success()/cancelled() 命中 0;控制已点亮(全文件命中 3)⇒ 真缺席
job 级 if: 短路	✅ :289-292,两个子句(payload 标签 + changeset-release bot 作者)
拒绝步骤被两个活标签读守卫	✅ :850-857,steps.labels.outputs.skip 与 steps.labels_settled.outputs.skip
hotlong 打标时刻	✅ timeline:labeled 'skip-changeset' by hotlong at 2026-09-18T05:38:18Z
Check Changeset 不在必查集	✅ 注册的 7 个 context 无它(直查 0 命中,控制点亮)⇒ 红是 advisory,⛔ 不挡队列

我改了 dev 的一个读数,并且这个改动是本卡最重要的新事实: dev 报「1 个开放 PR 会新被拒:#18765」。我 06:12Z 重量:#18765 已于 06:04:29Z 由 os-support-ai 合并(比 dev 的报告落地早 5 分钟)。⇒ ① 今天开放面的爆炸半径是 0,不是 1;② 更要紧的是,dev 用来论证「p1 条件未满足」的那个读数(最近 300 个 closed PR 中 193 个带标签合并、0 个碰别人的 changeset)刚刚翻了 —— #18765 就是那个 1。⭐ 这不是 dev 测错:它的数在取的那一刻是对的,这正是为什么读数要带取数时刻。

⛔ 我不据此单方面把本卡提到 p1:是否算「活违反」取决于问题②的答案 —— 若打标签就是那个确认动作,则 #18765 是通道正常工作,不是违反。定级跟着你对②的裁决走。

问题① 走哪条路

⭐ 先更正我自己:我在派发令 Zone 3 里建议的路线(「只让这一条拒绝不再认标签」)已被实测证伪,我在这里公开作废它。 它不够,理由是机械的而非偏好:job 级 if: 会跳掉整个 job,所以 job 内一个不认标签的步骤只在「标签晚于事件落地」时才触发 —— 那会得到「红一个 PR、绿一个一模一样的 PR」,恰是该 workflow 自己记录在案要避免的结果;且它完全不动 L3,拒绝对本卡这一类仍然不会打印。⇒ 记为 measured-insufficient,请勿再有人重新推导它。

• A —— job 内步骤取消标签豁免。已实测不足(见上)。
• B —— 在 pr-automation.yml 新开一个不读标签的 job,只跑「别人的 changeset」这条规则。关掉 L1/L2,L3 因独处而自动关掉。代价:复制一份 Check Changeset 会因为「别人的 PR 合进了 main」而变绿 —— merge ref 里的他人 changeset 被算成本 PR 新增的 #6129 merge-base 推导、新增 advisory check-run context、登记进 workflow-roster 门禁、门禁族 31 → 50(dev 实测)。
• C(我的推荐) —— 去掉 job 级 payload 短路,让步骤级守卫成为权威;然后把这条规则放进一个两个标签读都不认、并带状态函数条件(使兄弟步骤失败不能跳过它)的步骤。三层一次关完,不复制任何机械。 代价:每个带标签 PR 多一个 runner(今天 11/23),即短路当初存在的那个成本理由;另需 checker 的规则选择模式,以及消费者自测从 5 个可失败步骤变 6 个并写明豁免。

推荐 C 的第二个理由(长远轴):C 让那个 checker 已有的消费者自测变成真的 —— 它今天就断言「每个可失败步骤都尊重两个标签读」,仿佛步骤级守卫是权威,而 job 级 payload 读在背后静默推翻了它。C 使断言与现实一致;B 让矛盾继续存在于另一个 job 旁边。

⚠️ C 触人工地板:「每个带标签 PR 多跑一个 runner」是算力/配额形态的变化,按纪律那是你的字,不是席位的。这就是本卡进决策箱而非代裁的第二个独立理由。

问题② 什么动作算「确认」

新证据,⛔ 非重裁 Zone 1:hotlong(/docs/adr/ 的 CODEOWNER、两个授权批准账户之一)在 05:38:18Z 亲手给 #18765 打了 skip-changeset,而该 PR 正文已按 governing text 的处方声明了这一类并请求确认。

• A(我的推荐) —— 给「刻意修正」这一类自己的确认令牌(一个独立标签,或 checker 读得懂的 PR 正文标记),把 skip-changeset 收回它唯一声明的职责:本 PR 自己不发布任何东西。⇒ 与 governing text 一致(它要的是具名声明 + 确认,不是一个复用的标签),且 AI 作者无法靠「想让 CI 变绿」误触。
• B —— 让「这道门禁无论如何都红」字面成立:这一类永久带 advisory 红。最便宜,且与 Check Changeset 本就不是必查项一致。⛔ 注意 B 不只是退路,它已经是成文契约,且不需要任何新词汇。
• C —— 改门禁文字去描述实际行为。Zone 1 已裁补救是收窄,故 C 仅作为与之冲突的选项记录在此,⛔ 不推荐。

② 是你的字而非席位的:它决定「什么动作构成对一次发布说明修正的同意」,属同意/确认机制,在人工地板上。

并入本卡、⛔ 不另立孪生卡的发现

dev 报的 L3 步骤顺序压制我判定属本卡补救范围之内,故记在此不另开卡(⛔ 避免孪生):changeset-check 零状态函数 ⇒ 承载 #17712/#18160 两类拒绝的步骤继承隐式 success(),只要「Require a changeset」先失败就被 SKIP;而只修正别人说明的 PR 自己不加 changeset,所以那一步对本类永远先失败 ⇒ 拒绝文字对它要服务的那一类永远不打印。证据 run 35265359525 / 35266458091,控制 #18889 run 35313361879。若你要它独立追踪,它是本卡的 sub-issue;查重词:changeset-check step order · implicit success() skip · two-class refusal never prints。

另外三条 dev 标为 noted, not filed 的我已核为补救 PR 作者的承接项(失败步骤自己的处方把标签路线标 PREFERRED;Check Changeset 非必查;消费者自测把 5 个可失败步骤钉死),⛔ 均不单独立卡 —— 都会出现在实施者的 diff 里。

交付与配额

premise_still_valid: true · pr: null · files_changed: [] —— 按报告契约这是合法终报,我按再分诊输入复核,⛔ 不当失败派发。门禁:围栏面 31 条中 2 条实跑(--self-test EXIT=0「159 assertions over real temp git repos」、--base origin/main EXIT=0),其余 29 条 NOT MEASURED 且理由成立(零 diff 可判)。写入:mcp_calls 0、REST 写 1(本报告评论),均在预算内;配额 06:12Z 读 core 15000/15000。
