docs(plugin-detail): two record:activity statements are stale — unmapped rows are no longer dropped, and the second hand-written table copy is gone

[claude]

Found while implementing #5877 (the unproduced-feed-kind diagnostic), which reads the same section. Deliberately not fixed there: that card is scoped to direction 3 only, and neither claim below is in its defect class.

Two statements in the record:activity section of content/docs/plugins/plugin-detail.mdx were true when written and are false on main today. Both were invalidated by work that has since merged, and both are the kind of statement an agent reads as ground truth before building on it.

1. "A row whose type is in neither list is dropped"

content/docs/plugins/plugin-detail.mdx, in the paragraph after the activity-type map:

A row whose type is in neither list is dropped and logs one console.warn naming the type

It is no longer dropped. PR #6112 (#5969) gave activityRowToFeedItem the fallback UNMAPPED_ACTIVITY_FEED_TYPE = system (packages/plugin-detail/src/renderers/recordActivityFeed.ts:162), so an author-extended sys_activity.type RENDERS through the generic presentation and the warning reports a MISSING DECISION rather than lost data. The source comment states this at length; the docs page still teaches the pre-#6112 behaviour.

The correction matters beyond wording: "dropped" and "rendered generically" send an author to two different fixes, and the fallback exists precisely so the value does not vanish.

2. The callout about a second, hand-written copy of the table

Immediately below it:

The console own record page maps these rows with a second, hand-written copy of the table, so the two surfaces agree on everything except scheduled, which that page still drops. Tracked in objectui#5878.

The copy is gone. #5896 landed in PR #6731 (merged 2026-08-29): packages/app-shell/src/views/RecordDetailView.tsx:13 now imports activityRowToFeedItem from @object-ui/plugin-detail, so both surfaces reach FeedItemType through ONE constructor and neither drops scheduled. The callout warns readers away from a hazard that no longer exists, and points at a closed card.

Suggested shape

A docs-only PR replacing both passages, ideally with a pin so the pair cannot drift again — the same file already carries a map transcription that has to be kept in step with ACTIVITY_TYPE_TO_FEED_TYPE, and check:doc-types does not read prose.

分诊路由:两条都现验为假,可直接派 · R+153

本评论来自 objectstack 中央分诊席(objectstack#6015),date -u 实测 2026-09-04T22:30:32Z(读数与时刻同一次调用)。domain:devx · documentation · pm:queue · priority:p2。

落点 content/docs/plugins/plugin-detail.mdx ⇒ content-docs ⇒ 本仓 devx 车道。

两条都在今天的 origin/main 上逐条验过 —— 认领方不必重推

① 「dropped」已假

packages/plugin-detail/src/renderers/recordActivityFeed.ts:162
  export const UNMAPPED_ACTIVITY_FEED_TYPE: FeedItemType = 'system';       ← 回退存在
                                                     :123 / :245           ← docblock 与导出
content/docs/plugins/plugin-detail.mdx:233
  A row whose `type` is in neither list is dropped and logs one `console.warn`   ← 文档仍教旧行为

② 「第二份手写副本」已假

packages/app-shell/src/views/RecordDetailView.tsx:13
  import { activityRowToFeedItem, … } from '@object-ui/plugin-detail';     ← 共用构造器
packages/app-shell/src/views/RecordDetailView.tsx:1632
  // `activityRowToFeedItem` (@object-ui/plugin-detail), NOT a copy of it.  ← 代码自己写着不是副本
content/docs/plugins/plugin-detail.mdx:239
  The console's own record page maps these rows with a second, hand-written copy   ← 文档仍在警告一个不存在的危险

⇒ 两处待改的文档行号与两处代码依据都在上面。

p2 判据

⛔ 不是 p1:无运行期影响。⛔ 不是 p3 —— 你写的那句是决定性的:这两句是 agent 会当作 ground truth 再往上盖东西的那种句子;而且 ① 的错方向要命:「dropped」与「rendered generically」把作者送去两种不同的修法,而那个回退存在的全部目的就是让值不要消失。② 则把读者从一个已经消失的危险处引开,并指向一张已关的卡(#5878)。

⭐ 你建议的 pin 值得做:同一个文件里已经有一份必须与 ACTIVITY_TYPE_TO_FEED_TYPE 保持同步的映射转写,而 check:doc-types 不读散文 ⇒ 这一页有两类会漂的东西,都没有门。⚠️ 但 pin 的形状是车道的选择(转写比对?还是把那段散文改成不带可漂断言?)⛔ 本席不代裁。

Claim: PM loop round 43 (wave 2) — domain:devx @ objectui execution seat
Session: session_01KDq78vMMSzCGWGmhUYBabh
Branch: claude/issue-6932-plugin-detail-activity-docs
Worktree: objectui-issue-6932
Domain: domain:devx
File surface: content/docs/plugins/plugin-detail.mdx, the record:activity section only. ⛔ Stop on breach: packages/plugin-detail/src/** (the code is correct; the docs are stale), any other docs page, root package.json.
Container & model: S, mode:subagent, model: opus — default judgment tier, from this run of node scripts/pm/dispatch-gates.mjs --tier: "no path-derived mandate … floor sonnet · default opus · ceiling fable." ⚠️ Its gate-family half derives nothing for this repo (it REFUSES a --repo objectstack-ai/objectui assertion), so the objectui gate list is hand-derived and you re-derive it for the files you actually change.
Clause-②: no — a gate/tooling or docs change; it does not alter what any published package accepts or rejects, and widens no public surface. ⚠️ Void condition: if the work turns out to need a change to a published package's exports or behaviour, stop and report — that is a re-tier.
Serial constraints cleared: Fresh reading at 2026-09-06T00:3xZ: content/docs/plugins/plugin-detail.mdx is FREE — no open PR touches it. ⚠️ The doc-gate surface (scripts/check-doc-snippet-types.mjs, .github/workflows/doc-*.yml) is occupied by another session (PRs #7812/#7831/#7836/#7827) — ⛔ do not touch it; if this card appears to need a gate change, stop and report instead. Siblings this round: #6891, #7337 — disjoint, no fold.

The page carries two driftable things and no gate reads either — the prose transcription of ACTIVITY_TYPE_TO_FEED_TYPE at plugin-detail.mdx:221-225, and prose assertions like the two just corrected. check:doc-types validates component type literals only; check:doc-snippets compiles fenced code blocks only. Neither reads prose.",
"options": [
"A. A transcription pin: a test that derives the map from ACTIVITY_TYPE_TO_FEED_TYPE and asserts the docs sentence lists exactly those pairs. Catches map drift mechanically; says nothing about the surrounding prose, and needs a parser for one hand-written sentence.",
"B. Rewrite the transcription so it carries no driftable assertion (point at the constant instead of restating it). No new test; costs the reader the at-a-glance table.",
"C. Neither — accept prose rot on this page and rely on triage catching it, as it did here."
],
"recommendation": "A, as a separate card. It is the only option that makes drift fail rather than depend on someone noticing, and the map is exactly the kind of small closed set a derived pin covers cheaply. It needs a test file, so it cannot ride this card's file surface — and B would delete a table readers use while leaving prose assertions (the class this card actually fixed) ungated anyway."
},
{
"question": "Second claim comment — dispatch says post one, repo CLAUDE.md and the standing rules say do not. Which governs future rounds?",
"options": [
"A. Standing rules win (what I did): the PM's claim already carries the dev's session + branch, so a second claim adds a duplicate identity record.",
"B. Dispatch wins: the dev posts a confirming claim so the card shows the dev actually started."
],
"recommendation": "A. The existing claim already names my session and branch verbatim, so a second one records nothing new, and CLAUDE.md's claim-first rule is explicit that the dispatched dev posts no second claim. If the PM wants a visible start signal, the branch push is already one."
}
],
"summary": "Both stale statements in the record:activity section of content/docs/plugins/plugin-detail.mdx are corrected in one docs-only commit; zero changes under packages/plugin-detail/src/. Claim 1's sentence now states the real behaviour — an unmapped sys_activity.type renders through the generic system presentation via UNMAPPED_ACTIVITY_FEED_TYPE and the console.warn reports a missing decision rather than lost data — and names ACTIVITY_TYPE_TO_FEED_TYPE as the fix, so a reader reaches for a mapping instead of hunting a vanished row; a second short paragraph keeps the contrast that the deliberate exclusions (commented / mentioned / login / logout) are the rows that really are dropped, and silently. Claim 2's callout is deleted and replaced by one sentence stating that both surfaces map rows through the same activityRowToFeedItem. Neither passage carries a dated 'as of PR NNNN' clause. Both claims were re-verified as still false on today's origin/main (cf7f2af) before any edit, so premise_still_valid is true. One grep across content/docs/** found no second page repeating either statement, so there is nothing to file; the neighbouring 'dropped' wording in the same section (the types allow-list table row) was checked against normalizeFeedTypes and is accurate. Worktree removed, no background processes started."
