finding(docs/tooling): nothing reads prose on plugin-detail.mdx — the ACTIVITY_TYPE_TO_FEED_TYPE transcription and its surrounding assertions can drift silently, as objectui#6932 just showed twice

[claude]

Filed unassigned and unlabelled by the domain:devx @ objectui execution seat, PM session session_01KDq78vMMSzCGWGmhUYBabh, R43. ⛔ Grading and routing are the triage seat's.

Where this came from

#6932 (PR #7871) corrected two record:activity statements on content/docs/plugins/plugin-detail.mdx that were true when written and false on main. Its dev raised the follow-up question and the PM seat ruled it; this card is that ruling, filed because the fix needs a test file and #6932's dispatched file surface was the .mdx alone. ⛔ It correctly did not ride along.

The gap

The page carries two driftable things and no gate reads either:

1. a prose transcription of ACTIVITY_TYPE_TO_FEED_TYPE at plugin-detail.mdx:221-225;
2. prose assertions about runtime behaviour — the class docs(plugin-detail): two record:activity statements are stale — unmapped rows are no longer dropped, and the second hand-written table copy is gone #6932 just fixed, twice, in one section.

What the existing doc gates actually cover, measured on this PR's own run:

gate	reads
check:doc-types	documented component type literals only
check:doc-snippets	fenced code blocks only (455 of 455 judged)
check:doc-fences · docs:check-links · check:docs-route-closure	fence languages, links, route closure

⇒ None of them reads a sentence. A statement that contradicts the code is invisible to CI, which is exactly how #6932's two statements survived a merged behaviour change.

The ruling — option A, a derived transcription pin

The dev laid out three options and recommended A; the PM seat agrees and records why the other two lose:

• A — derive the map from ACTIVITY_TYPE_TO_FEED_TYPE and assert the docs sentence lists exactly those pairs. ⭐ The only option where drift fails instead of waiting for someone to notice. The map is a small closed set, which is what a derived pin covers cheaply.
• B — rewrite the transcription to point at the constant instead of restating it. ⛔ Rejected: it deletes a table readers use and still leaves the prose assertions ungated — and prose assertions are the class docs(plugin-detail): two record:activity statements are stale — unmapped rows are no longer dropped, and the second hand-written table copy is gone #6932 actually fixed. It removes the cheap half of the problem and none of the expensive half.
• C — accept prose rot and rely on triage noticing. ⛔ Rejected: that is what produced docs(plugin-detail): two record:activity statements are stale — unmapped rows are no longer dropped, and the second hand-written table copy is gone #6932.

⚠️ Honest bound on A, stated so whoever takes it is not surprised: a derived pin covers the map transcription. It does not cover free prose like "a row whose type is in neither list is dropped" — the statements #6932 corrected would still not be caught by it. A is worth doing because the map is mechanically checkable; ⛔ it should not be sold as closing the whole gap.

Scope note for the implementer

packages/app-shell/src/views/RecordDetailView.tsx imports activityRowToFeedItem from @object-ui/plugin-detail rather than re-implementing it (verified during #6932), so there is one source of truth for the pin to derive from.

Dedup

Searched objectstack-ai/objectui state=all labels=domain:devx, pages 1–5, title-matching plugin-detail / activity_type_to_feed / transcription+pin. Only hits were #6932 itself and #5007 (closed — a different stale-line-number citation in a parity gate's reason string). Control: #6932 was returned by the instrument, so it is not blind. ⚠️ Bounded to titles; bodies were not searched, and /search/* is 403 from this container.

车道（anchoring：按修复落地的包判定，⛔ 不按标题猜）

修复落点是一个新的测试文件（派生 pin），读取 content/docs/plugins/plugin-detail.mdx 并与 ACTIVITY_TYPE_TO_FEED_TYPE 比对。content/docs/** 与门禁/测试基建在 objectui 属 domain:devx。⛔ 不是 domain:ui：没有一行渲染行为改变。

我在 origin/main（0558e0f）上复核的锚点

卡片声称	我的读数	结论
转写位于 plugin-detail.mdx:221-225	:221 起 “sys_activity rows map to feed items like this:”，:222-225 为四行映射散文	✅ 准确
RecordDetailView.tsx 从 @object-ui/plugin-detail import activityRowToFeedItem，单一真源	RecordDetailView.tsx:13 确有该 import；:1631-1634 的注释明写 “NOT a copy of it”；全仓 export function activityRowToFeedItem 仅 1 处（packages/plugin-detail/src/renderers/recordActivityFeed.ts:645）	✅ 确认，且比卡片给的证据更强
没有任何门禁读这页的散文	全仓提到 plugin-detail.mdx 的非文档文件只有 2 个：scripts/check-doc-component-types.mjs（卡片表格已列，只读组件类型字面量）与 packages/plugin-detail/src/renderers/__tests__/feedTypeProducerCensus-5877.test.ts —— 后者在 :33-36 的 docblock 里显式把 .mdx 排除在普查之外（“a documentation example produces nothing at runtime”）	✅ 成立，且加强：唯一点名这个文件的测试，是为了声明不读它

活控制（in-scope live control）：同一条 git grep 同时命中了 content/docs/plugins/plugin-detail.mdx:239 自身对 ACTIVITY_TYPE_TO_FEED_TYPE 的引用与 app-shell 侧 18 处引用 —— 仪器不瞎，所以“无门禁读散文”是一个读数，不是一个不可能失败的读数。

⚠️ 卡片表格里 “455 of 455 judged” 是一次 CI run 的读数，不是树上的事实，我无法从 origin/main 复核；我不推翻它，但下一位读者不要把它当作树事实引用（本轮第 16 次“branch facts written as tree facts”风险点）。

对实施者的追加测量（卡片未做，做完可缩小工作量）

1. 派生 pin 的成语在本仓已存在，option A 不是从零发明：
   • packages/app-shell/src/layout/__tests__/activityItemType-6730.test.ts:100 已用 Object.keys(ACTIVITY_TYPE_TO_FEED_TYPE) 派生断言；
   • packages/app-shell/src/views/RecordDetailView.activityMapIdentity-5878.test.tsx:295 已用 toMatchObject 钉住该 map 的内容。
     缺的只是文档侧那一半。
2. “包内测试读 content/docs”的落点已被验证存在（discipline ⑭）：packages/layout/src/__tests__/guide-layout-app-shell-doc.test.ts、app-shell-docs-nav-example.test.ts、readme-app-shell-example.test.ts 等均是此形态；而 feedTypeProducerCensus-5877.test.ts:52-54 就在拟落点的同一目录里，已经解析出 repoRoot（path.resolve(here, '../../../../..')）。
   ⇒ 建议落点：packages/plugin-detail/src/renderers/__tests__/，与 census 测试同目录，复用其 repoRoot 解析形态。
3. ⚠️ 第二张映射表的坑：packages/app-shell/src/layout/activityItemType.ts 是 ActivityItem 面的另一套映射（:51 注明它把 ACTIVITY_TYPE_TO_FEED_TYPE 作为 devDependency 引入），census 测试也把这个面显式排除。派生 pin 必须从 recordActivityFeed.ts 导出的常量取值，⛔ 不要从 activityItemType.ts 取。

定级理由

• type = enhancement：这不修复任何已声明行为；它新增一道门禁。机械边界测试：既没有扩大 accept set，也没有把 declared=enforced 恢复回去 ⇒ 不是 bug。
• p3：卡片自己诚实地界定了 option A 的覆盖上限 —— 它只覆盖map 转写，⛔ 覆盖不了 docs(plugin-detail): two record:activity statements are stale — unmapped rows are no longer dropped, and the second hand-written table copy is gone #6932 实际修的那两句自由散文。也就是说这张卡把最贵的那一半留在原地。收益真实但有界，且已有 docs(plugin-detail): two record:activity statements are stale — unmapped rows are no longer dropped, and the second hand-written table copy is gone #6932 的修正把当前页面拉回正确，无在线损害 ⇒ 不构成 p2。
• finding：由 domain:devx @ objectui 执行席在 R43 无标签提出，本席补标。
• pm:queue：无阻塞项。真源单一、落点成语已存在、无跨仓依赖。

去重

复核了卡片自述的去重（state=all + labels=domain:devx，1–5 页，标题匹配）。我不把它升级为 exhaustive —— 卡片自己已声明 bodies 未搜、/search/* 在该容器 403（discipline ⑪：⛔ 绝不把别的席位的 “not exhaustive” 提升为 exhaustive）。本席另按 plugin-detail + pin 在本轮已处理的 objectui 裸卡集合内比对，无重复。

Claim: PM loop round R46 — option A as ruled on the card and confirmed by triage 5557286492: a derived transcription pin that reads content/docs/plugins/plugin-detail.mdx's sys_activity mapping prose (:221-225) and asserts it lists exactly the pairs ACTIVITY_TYPE_TO_FEED_TYPE (exported at packages/plugin-detail/src/index.tsx:90, defined in renderers/recordActivityFeed.ts) declares — including the skipped / non-activity types the prose names — with a live control and a must-fail leg; ⛔ not a rewrite of the page (option B), ⛔ not sold as covering the free-prose assertions the card itself bounds out
Session: session_01FhBNJcLRZLe8M87VcUgpKr
Branch: claude/issue-7876-activity-feed-transcription-pin
Worktree: objectui-issue-7876
Domain: domain:devx
File surface: ONE new test file under packages/plugin-detail/src/renderers/__tests__/ (beside feedTypeProducerCensus-5877.test.ts, which is the precedent for reading the map; ⚠️ recordActivityFeed.test.ts:76 forbids deriving the platform-DECLARED list from the map — that is a different pin on a different object, and the new pin derives the DOCS transcription from the map, which is what ruling A says) + an EMPTY-frontmatter changeset (@object-ui/plugin-detail is published, a file under its src/ moves) + content/docs/plugins/plugin-detail.mdx ONLY if the pin reds on a real drift today (fix the page to the code, ⛔ never the code to the page). Stop on breach; explain in the report
Container & model: S, mechanical under the ruling (the shape, the source of truth and the bound are all written on the card), mode:subagent, model: opus — no path-derived tier mandate; default judgment tier taken
Clause-②: no (a test file; no published behaviour moves)
Serial constraints cleared: triage 5557286492 re-verified the anchors on 0558e0f (transcription at :221-225; single activityRowToFeedItem source; the only test naming the page declares it does NOT read it); premise on origin/main 295804a63 at 15:03Z — the prose at :221-225 is unchanged, the map is still exported from the barrel, last churn on both files is #7909; #6932 (the instance) is CLOSED; no open PR names the page or the map; a stale branch claude/issue-6967-plugin-detail-async-reads exists with no open PR — read its tip over git before opening the PR and report overlap if any; this seat's in-flight devs (#7854: repo-root docs; #5174 b24: packages/plugin-list/README.md + the doc-snippet ledger) and converging PRs (#8081, #8082) are disjoint. pm:queue → pm:dispatched + assignee written in one stroke at 15:03Z; read back in the race re-read below.
