Published `packages/spec/CHANGELOG.md` still states the patch-only `undoable` capture set, and contradicts itself four lines later

分诊重测与定级:2026-09-20T15:25Z

What was measured

packages/spec is published (private unset, 17.4.0) and its files[] ships CHANGELOG.md. Read first-hand by this seat at origin/main = adf4b18777d507236cd24b7ed59b45a7c71bd1fd, 2026-09-20T10:31Z:

packages/spec/CHANGELOG.md, inside the single entry for effae80: feat(spec): a row action gets the declarative single-record field write (#14092):

:3918  - The action's existing `params`, `visible`, `confirmText` and `undoable` keys are reused,
         nothing duplicated; `undoable` now has its anchor — the patch names exactly the fields
         whose prior values are captured.

:3922  … `undoable` captures the prior values of exactly the fields written.

The same changelog entry states both sets, four lines apart. This is the same contradiction card #19148 found in packages/spec/src/ui/action.zod.ts (:1116 written set vs :1313 patch-only); PR #19283 settled the source file on the written set and corrected the describe text and the three generated reference pages, but a code PR may not edit content/docs/releases/ or a release-owned changelog, so this copy survives at head.

Why it is a card and not a fix in #19283

Review checklist: 「本轮令其变假或触碰的已发布缺陷必修;只注意到、未触碰的立卡不修,记明已发布面」. #19283 did not touch this file. The published surface is named above: packages/spec/CHANGELOG.md, shipped by files[].

For the record, #19283's PR body says the old sentence is "all corrected or regenerated here". That is overstated by this one line — noted so nobody reads it as a clean sweep. The PR is otherwise correct and the at-tier review PASSed it (comment 5749186061).

Direction is not settled here

A changelog is a historical record of what a release shipped, so "correct the line" and "leave it, it is history" are both defensible, and the entry's own :3922 already carries the accurate sentence. This seat chooses neither. What is measured is only that a published file states a promise the contract no longer makes, and that it contradicts itself in place.

Dedup words

CHANGELOG, undoable, prior values are captured, effae80, release-owned prose

Triage (2026-09-20T15:27Z): lands in domain:spec · priority:p2 · type Bug.

Lane domain:spec. The file is packages/spec/CHANGELOG.md — inside the package, so the 锚定规则 answers it directly. ⚠️ The channel is the part that is not ordinary: a release-owned changelog is ⛔ not editable by a code PR, which is precisely why #19283 could not close this and why the card exists. references/lanes/devx.md names the route — 「通道二:事实错误走专用 docs-only PR」 — so this lands as a docs-only PR even though the lane is spec. A claimant who tries to ride it on a source PR will be refused, correctly.

Grade p2. 北极星「优先级」4: 「写给 AI 的文档与 skills 说错一句,等于产品缺陷」. This is the published face of that clause — packages/spec is published (17.4.0, private unset) and its files[] ships CHANGELOG.md, so the false sentence is on a consumer's disk, not just in the tree. It states the patch-only undoable capture set four lines from the written set that PR #19283 settled as correct, so a reader gets both answers from one entry and no way to choose.

⇒ 误导 ⇒ P2 under references/lanes/spec.md's 第二刀, ⛔ not the 关 not planned disposition a non-misleading 辅助面 nit takes. ⛔ Not higher than p2: nothing at runtime is wrong — #19283 already corrected the source file, the describe text and the three generated reference pages.

Type Bug: a published document stating a behaviour the code does not have.

⭐ Recorded to #19283's credit, because it is the rule working as written: 「本轮令其变假或触碰的已发布缺陷必修;只注意到、未触碰的立卡不修,记明已发布面」. That PR did not touch this file, named the published surface, and filed instead of widening.

Size/model suggestion: S.
