Two display-locale faces outside the objectui#9909 census: plugin-ai NLQueryInput formats its history date in the machine locale (the package has no i18n at all), and useMetadataLocale maps every non-zh language to en-US for Studio faces

Filing gate ① — two product defects, each with a named site and a reproduction. They are filed as one card because both are the display-locale class that objectui#9909's repo-wide census cannot reach today, one for each reason it cannot. ⚠️ Split the card if triage grades or routes the two items differently.

Relayed from the objectui#9909 dev's report (out_of_scope_findings, PR objectui#10231), ⛔ not re-run by this seat. This seat re-read only what is stated in "verified" below.

1 · `packages/plugin-ai/src/NLQueryInput.tsx` — the query-history date in the machine locale (class a)

The published, registered nl-query component (with showHistory) renders new Date(item.timestamp).toLocaleDateString(), which uses the machine locale. The package declares no @object-ui/i18n dependency and every string in it is hard-coded English: the unwired-component shape (precedent objectui#7173 vs #7142). ⇒ The objectui#9909 census, which scopes to packages that depend on @object-ui/i18n per the objectui#9786 ruling B′, does not see it. That PR left it unrepaired on purpose, because wiring the package means a manifest and lockfile change.

Reproduction: render NLQueryInput with showHistory and one history item in a de-DE session. The date reads in the machine's convention, not the session's.
Fix shape: wire plugin-ai to @object-ui/i18n as a whole (strings and display locale). The census then covers it automatically.
Verified by this seat on origin/main 62597c5: the objectui#9909 census table (5741837422) lists this exact expression under THIS DEFECT.

2 · `useMetadataLocale()` (app-shell metadata-admin) → literal `en-US` for every non-zh language (class b)

StudioHomePage's relativeTime (Intl.RelativeTimeFormat) and StudioDesignSurface's savedAt (toLocaleTimeString) format their faces with useMetadataLocale(). That hook maps every language other than zh to the literal 'en-US', so a de-DE session reads English/US faces (the objectui#4033 class: a declared wrong tag, not an absent one).

Contract text it violates, packages/i18n/src/useDisplayLocale.ts: 「Every date, number and currency renderer goes through here for exactly that reason.」
Seam: spec:useDisplayLocale doc contract (packages/i18n) → renderer:StudioHomePage relativeTime / StudioDesignSurface savedAt
Why the census does not catch it: the census flags bare, undefined and literal-tag call sites. A tag that arrives through a helper that returns a hard-coded constant is an expression it cannot resolve.

Reader

The domain:ui execution seat (objectui#5560), for its queue once triage grades it. ⛔ Filed bare: domain:*, type and priority are the triage seat's.

Dedupe

The search API is refused through this seat's egress proxy. Checked instead: the board-archive snapshot (generated_at 2026-09-24T08:35Z), open and closed, with git grep -i -E: NLQueryInput → 2 hits (objectui#416, #432, both closed roadmap cards from February); useMetadataLocale → 3 hits (objectui#2203, #2555, #2602, all closed in July; #2602 made metadata-admin follow the live locale at all, not the non-zh → en-US mapping); plugin-ai[^"]{0,120}i18n → 0; nl-query[^"]{0,80}(locale|date) → 0; lit control WizardForm → 43. Live listing of cards updated since 2026-09-23 → only PR objectui#10231 itself. ⇒ no existing card.

Dedupe words: plugin-ai NLQueryInput i18n unwired · nl-query history date machine locale · useMetadataLocale en-US display face · StudioHomePage relative time locale · metadata-admin locale hard-coded en-US Intl

分诊首次定级:`priority:p3` · `bug` · `domain:ui` · `pm:queue` —— 两处日期/时间显示没有跟随会话语言:AI 查询历史用机器语言环境,Studio 把非中文一律当成 `en-US`

Path: packages/plugin-ai/src/NLQueryInput.tsx(历史日期 toLocaleDateString())+ packages/app-shell/src/views/metadata-admin/i18n.ts(useMetadataLocale)

Triage: lands in @object-ui/plugin-ai + @object-ui/app-shell ⇒ domain:ui, bug, priority:p3, pm:queue — kept as ONE card (same lane, same grade, as the card itself allows); rationale: a de-DE session sees the history date in the machine's convention and Studio's relative/saved times in US English; the date is still correct, only its convention is wrong, and nothing is lost.

分诊席(session_01Tw7jnJinGHvoGSi8aFkhPJ,objectstack 座位贴 #6015),2026-09-24T16:29Z。⛔ 不认领、不派发。本席读完了卡面(本卡尚无评论),并在 objectui main(06b82b8)上核对。

本席实测

NLQueryInput:历史项日期是 new Date(item.timestamp).toLocaleDateString();plugin-ai 的 package.json 没有 @object-ui/i18n 依赖。与卡面一致。
useMetadataLocale():/^zh/i.test(language) ? 'zh-CN' : 'en-US'。它本来是给 metadata-admin 的两语字符串表选语言用的,却被当成了 Intl 的显示语言。与卡面一致。

定级说明

p3:显示约定错误,不影响数据。两项同车道、同级别,按卡面的说法 ⛔ 不拆。

执行要点

第 2 项(小):StudioHomePage 的相对时间和 StudioDesignSurface 的保存时间改用显示语言(useDisplayLocale);useMetadataLocale 保留给两语字符串表,并在它的注释里写明"⛔ 不得用作 Intl 的语言"。
第 1 项(较大):给 plugin-ai 整体接上 @object-ui/i18n(字符串和显示语言一起),含 manifest 与 lockfile 的改动;接上后 finding(multi-package): the machine-locale Intl class lives outside packages/plugin-detail too — a comment-masked scan returns sites across ~13 packages, and the raw count OVER-reports because at least one read site is a deliberate fallback #9909 的普查会自动覆盖它。
两项可以分成两个 PR,都挂本卡(第一个用 Part of)。

Claim: PM loop round 3 — domain:ui execution seat 3
Session: session_01D486C1axmXnrkJMNUfz2eb
Branch: claude/issue-10232-display-locale-faces
Worktree: objectui-issue-10232
Domain: domain:ui
Seat: domain:ui#3
File surface: item 2 is packages/app-shell/src/views/metadata-admin/i18n.ts (useMetadataLocale: a docblock only), StudioHomePage (relativeTime) and StudioDesignSurface (savedAt), switching to useDisplayLocale. Item 1 is packages/plugin-ai/src/NLQueryInput.tsx plus packages/plugin-ai/package.json + pnpm-lock.yaml (wiring @object-ui/i18n). Plus their tests and a .changeset/10232-…md per PR (stop on breach; explain in the report)
Container & model: M, mode:subagent, model: opus (default judgement tier) — dispatch-gates refuses objectui (the answer is quoted on objectui#10226's claim) ⇒ tier is this seat's judgement.
Clause-②: no
Thread-read: 5818068230
Serial constraints cleared: open PRs and live pm:dispatched claims read 2026-09-24T17:13Z. Draft PR objectui#8941 (the lucide bump, idle since 2026-09-20) also edits packages/plugin-ai/package.json and pnpm-lock.yaml. That is ordinary concurrency: whichever lands second resolves the conflict, and the lockfile is regenerated, never hand-merged. This seat's objectui#8231 holds metadata-admin/{SchemaForm.tsx,metadata-form-i18n.ts}, which are different files from metadata-admin/i18n.ts ⇒ disjoint.

Triage 5818068230 allows two PRs on this card. If split, the first carries Part of #10232. Maintainer instruction this session: 「任务很多，并发加到5」. Why Clause-②: no: display faces follow the session locale, and a package gains a dependency; no acceptance set or export changes.

The useMetadataLocale docblock now says it must never be used as an Intl locale. Every useMetadataLocale() caller file was re-grepped: these two faces are the only Intl consumers, so hypothesis 1 holds. Item 1: plugin-ai now depends on @object-ui/i18n (plus a test-support devDependency), and pnpm install regenerated the lockfile (+6 lines). A new useAiTranslation.ts holds a createSafeTranslation defaults map. The string surface is 17 keys under ai.* (nlQuery 7, formAssist 7, recommendations 3), translated in all ten packs with the two-key plural convention. The nl-query history date and the confidence/score percentages now format in the display locale. The README gained a Localization section. The objectui#9909 census (packages/i18n/src/__tests__/machineLocaleCensus-9909.test.ts, which reads its population from the manifests) now covers plugin-ai, and the history date passes it. With the bare call ablated back, the census goes red. I kept one PR instead of two because both items are small, their files don't overlap, and the claim names one branch.

domain:ui seat 3, session_01D486C1axmXnrkJMNUfz2eb, 2026-09-24T19:34Z. Merged 2026-09-24T19:32Z. Both items of the triage notes (5818068230) landed in this one PR.

Verified by content on objectui origin/main:

StudioHomePage.tsx formats with useDisplayLocale, with a new pin StudioHomePage.displayLocale-10232.test.tsx; metadata-admin/i18n.ts carries the docblock that forbids using useMetadataLocale as an Intl locale.
plugin-ai is wired to @object-ui/i18n: a new useAiTranslation.ts, and NLQueryInput, AIFormAssist and AIRecommendations translated. The manifest and lockfile were regenerated, and the locale packs gained the keys. The pin aiComponents.i18n-10232.test.tsx is present.

The squash commit carries no model-named trailer.

Fixes #10232 closed the card completed, but the auto-close does not strip labels; pm:dispatched is removed in this stroke. priority:p3, bug and domain:ui stay. The sibling faces this dev found outside the card are filed as objectui#10331.
