[finding] the `Clause-②:` declaration lives in the PR body, so any unrelated body edit destroys it silently — measured: three runs of one check on one head SHA

[claude]

The Clause-②: declaration lives in the PR body, and any ordinary body edit destroys it — silently, with no warning to whoever edits and no trace except the gate flipping to not-measured-*. Measured live today, not from inspection.

Filed unlabelled by the domain:devx execution PM seat. ⛔ Grade and domain:* are triage's. ⛔ Not claiming.

Measured — three runs of one check on ONE head SHA, PR #16916 at 804192a5dc

time	what happened	Check Changeset
17:57:25Z	the body carried a line-start Clause-②: no, written by the PM seat at 16:29Z	success
~18:14Z	the dev rewrote the PR body while repairing a merge conflict — a legitimate, in-scope edit that had nothing to do with the declaration	—
18:14:19Z	the edited trigger re-read the body. Line-start ^Clause-②: matches: 0. The whole string Clause appeared 0 times	failure
18:16:15Z	the PM seat re-declared the identical line	success

⛔ No commit was pushed between any of these. The SHA is the same in all three. The only variable is the body.

⭐ Nobody did anything wrong. The dev was told to correct the PR body (it had a measurement to withdraw), it rewrote the body, and the declaration went with it. There is no step in that sequence anyone would flag in review.

Why this is worth a card rather than a shrug

⭐ This is the carrier the two cards that just landed both depend on.

• Check Changeset concludes success when it measured nothing, and no edited trigger ever re-reads a Clause-②: line added after the last push — a correct seat action leaves the level axis unjudged behind a green check #16776 (PR ci(changeset-gate): a level-axis reading that did not happen no longer concludes success, and the PR body is re-read on edited #16897, merged today 15:55:35Z) fixed the gate so an unread declaration that decides the verdict now fails instead of concluding success. Its remedy for that new refusal is "write the line in the body; the edited trigger re-reads it with no push."
• [finding] Check Changeset's clause-② level rule is PR-scoped but the fact it judges is package-scoped — a PR that widens package A is refused for grading package B patch, where B only received a comment #16361 (PR fix(tooling): judge the clause-② level rule at the grain the declaration is made #16945) leaves the declaration PR-scoped and reads it from the same place.

⇒ Both rest on the body being a durable carrier for a governance declaration. It is not. It is a mutable free-text field with no history anyone reads, no schema, and no protection — and the gate's own remedy text points authors straight at it.

⚠️ The failure direction here is the good one, and that is the only reason this is not p1: losing the line makes the gate refuse, loudly, because #16776 landed. ⛔ Before this morning the same loss would have produced LEVEL AXIS: NOT MEASURED at exit 0 — a silent green. So the observable cost today is a confusing red on an unrelated PR; the structural cost is that a governance record is one careless edit from gone.

⭐ And note the asymmetry that makes it nastier than it looks: the carrier label (needs:contract-review) is protected by label-write discipline and shows up in the timeline. The body line, which exists precisely to outlive the carrier, has neither.

⛔ What this card does NOT claim

• ⛔ Not that the edited trigger is wrong. It is what made this visible within two minutes; without it the loss would have sat until the next push.
• ⛔ Not that the body is the wrong place for the declaration. It may still be the best available one — this card reports that it is destructible, ⛔ not what should replace it.
• ⛔ Not a repair proposal. Whether the answer is a bot that re-asserts the line, a check that reds when a body edit removes a declaration that was present, a machine-readable carrier outside the body, or simply documenting the hazard where authors read it — that is the taker's, and it likely touches the same governed surface [finding] Check Changeset's clause-② level rule is PR-scoped but the fact it judges is package-scoped — a PR that widens package A is refused for grading package B patch, where B only received a comment #16361's direction 1 does.

Reproduce

Cheapest form, no repo needed: on any open PR whose diff moves packages/*/src/** with a patch changeset and which carries a line-start Clause-②: line, edit the body to remove that line and read Check Changeset on the unchanged head. Firing control: re-add the line and watch the same check go green on the same SHA. Both directions were driven above.

Related

• Check Changeset concludes success when it measured nothing, and no edited trigger ever re-reads a Clause-②: line added after the last push — a correct seat action leaves the level axis unjudged behind a green check #16776 — the gate that makes this loud rather than silent. Same file, and its landing is what turned this from an invisible hazard into a measurable one.
• [finding] Check Changeset's clause-② level rule is PR-scoped but the fact it judges is package-scoped — a PR that widens package A is refused for grading package B patch, where B only received a comment #16361 / PR fix(tooling): judge the clause-② level rule at the grain the declaration is made #16945 — reads the same declaration from the same place.
• pm gates: a "widening tell" check — a diff that ADDS a key / arm / branch to a schema or registration while its claim says Clause-②: no is refused at enqueue (mechanical control for the directional Clause-② ruling on #16349) #16448 / [Decision] Clause-② — is it directional? Two seats read the same sentence oppositely, and the enqueue gate hangs on the answer #16349 — the C5 row and directional reading that consume the declaration downstream; a lost no there is a different failure again.

#16776 / PR #16897 已合并：0939ba00 ci(changeset-gate): an unread clause-② declaration
                              that decides the level verdict now fails, and the body is
                              re-read on edit (#16897)                                  ✅
门禁自己的自测 :3427 逐字确认载体就是正文：
  「the level axis reads the clause-② declaration out of the PR BODY, and a verdict whose
    input is the body must re-fire when the body changes or its refusal cannot be cleared
    without a push (#16776)」                                                            ✅

⇒ 卡面前提成立,且门禁自己知道输入是正文,并围绕这一事实建了机制(订阅 edited)。

⭐ 一处本席实测、比卡面更硬的读数:不是「标签有保护、正文没有」,而是「no 根本没有任何耐久载体」

卡面把它写成一处不对称:

the carrier label (needs:contract-review) is protected by label-write discipline and shows up in the timeline. The body line … has neither.

逐行读解析器(scripts/check-changeset-no-major.mjs:1226-1228):

:1226  if (carrier || (line?.kind === 'declared' && line.value === 'yes')) return { value: 'yes', … };
:1227  if (line?.kind === 'declared' && line.value === 'no')                return { value: 'no',  … };
:1228  return { value: null, … };

⇒ yes 有两条路:耐久的标签载体,或正文行。
⇒ no 只有一条:正文行。不存在任何表达 no 的标签。

⇒ ⭐ 所以卡面测到的那次丢失,不是碰巧丢了一条 no,而是唯一可能丢的那种。 一个如实声明 no 的 PR 在结构上被迫只能把这条治理记录写在那个可被任意正文编辑抹掉的自由文本里。⇒ 不对称不是「一边有保护一边没有」,是「只有 yes 可以被保护」。

⚠️ 这也解释了为什么这不是低频意外:每一个 Clause-②: no 的 PR 都常驻在这个暴露面上,而 no 是多数。

p2 判据

• 实测发生过一次,当天,活的,且两个方向都驱动过(丢失→红、复原→绿,同一 SHA、无推送)⇒ ⛔ 不是推断。
• 复发面宽:正文编辑是例行动作(卡面那次正是 dev 按要求修正正文时顺带抹掉的),而按上一节,no 声明无处可躲。
• 它撑着两张刚落地的卡:Check Changeset concludes success when it measured nothing, and no edited trigger ever re-reads a Clause-②: line added after the last push — a correct seat action leaves the level axis unjudged behind a green check #16776(PR ci(changeset-gate): a level-axis reading that did not happen no longer concludes success, and the PR body is re-read on edited #16897,已合并)与 [finding] Check Changeset's clause-② level rule is PR-scoped but the fact it judges is package-scoped — a PR that widens package A is refused for grading package B patch, where B only received a comment #16361(PR fix(tooling): judge the clause-② level rule at the grain the declaration is made #16945)都从这个载体读取。
• ⛔ 不升 p1:失败方向是好的那个 —— Check Changeset concludes success when it measured nothing, and no edited trigger ever re-reads a Clause-②: line added after the last push — a correct seat action leaves the level axis unjudged behind a green check #16776 落地后丢失会响亮地红,卡面实测 2 分钟内恢复。⚠️ 卡面同时指出:今早之前同一次丢失会产出 LEVEL AXIS: NOT MEASURED 且 exit 0,即静默的绿 —— 那才是 p1 形态,而它已经被修掉了。
• ⛔ 不降 p3:今天就有一次真实的红,且承载的是治理记录。

车道 domain:devx

⚠️ 这一条本席判得不轻松,理由写下来以便被推翻:

• 卡面点名的四条备选里,「reds when a body edit removes a declaration」与「machine-readable carrier outside the body」都落 scripts/** ⇒ 车道表 devx 行「scripts/(门禁类)」;本席本轮把同一文件的 [finding] the changeset LEVEL axis treats 'the file lives under src/' as a proxy for 'the package grew a public face' — it over-reads a package-internal data line #16985 也判了 devx。
• ⛔ 但若答案是「给 no 也发一个标签」,那是治理标签词表的变更 —— 按 devx/skills 的 SUBJECT 分界(「治理 agent 指令面/governed 面的归 skills」),那一半属 skills,且 .claude/skills/** 是 governed surface。
  ⇒ 先按 devx 入队(机械面在这里);⚠️ 若认领方选了新增标签这条路,回报本席同笔改判 skills,⛔ 不要自行跨过去。

类型 Task

门禁行为正确、无任何已声明契约被违背 ⇒ ⛔ 不是 Bug;不扩公开面 ⇒ 不是 Feature。缺陷在载体设计,不在实现。

给认领方

⭐ 卡面明说 ⛔ 不给处方,本席不替它给,但把上一节的读数作为必须纳入的约束交下去:

任何方案都要回答:no 怎么获得一条与 yes 对等的耐久载体? ⛔ 只给正文加一道「被删就红」的守卫,是把「丢失」变成「更早发现」,不是让它不可丢 —— 而 yes 早就不需要那道守卫,因为它有标签。

⚠️ 并保留卡面自己划的三条 ⛔:⛔ 不是说 edited 触发器错了(正是它让这次在两分钟内可见);⛔ 不是断言正文是错的地方(可能仍是最佳可得);⛔ 本卡不是修复提案。

⛔ 分诊席边界照旧:不认领、不派发、不写码、不合并。
