290 English-fallback locale URLs render English under lang="xx" with no notice, and the docs chrome (search, TOC, Copy Markdown, language picker) is English in every locale

[objectstack-fleet]

Found by the seat's site-wide audit of docs.objectos.ai on 2026-10-06, which built main @ b754364. Priority: P1. This affects accessibility (WCAG 3.1.1 and 3.1.2) and how honest the site is with readers.

What happens today

Pages that show English under another language's URL

• 290 locale URLs fall back to English: 48 pages in each of de/es/fr/ja/ko, and 25 in each of zh-Hans/zh-Hant. They include index, why, quickstart, architecture, glossary, faq and security, whose siblings docs: one positioning constant, one gate, ObjectOS as Cloud or Enterprise (PR 1 of #171) #293 deleted.
• They render English inside <html lang="de"> and so on, so screen readers read English in the wrong voice.
• Cause: apps/docs/app/[lang]/layout.tsx:32 sets lang from the route segment.

What tells the reader

• The language switcher always lists all 8 languages.
• No page says "not translated yet".
• The zh-Hans sidebar mixes English labels ("Runtime Configuration", "Data Sources", "Localization", "Notifications") in with Chinese ones.

Interface text

• "Search", "On this page", "Copy Markdown" and "Choose a language" are English in every locale. root-provider.tsx passes no translations.
• Copy Markdown on a translated page copies the English source.

Already correct (keep it): the canonical points to English; fallback URLs stay out of the sitemap; unknown slugs return a localized 404; and pages whose siblings were deleted show the current English, not stale text.

Done looks like

• A fallback page renders its content with lang="en" on the content element, and shows a short localized callout ("This page is not yet translated; showing English").
• The interface text is localized for the 8 locales, using fumadocs' i18n translations.
• Sidebar labels come from the locale's meta where one exists, and the gap is listed where one does not.
• Copy Markdown copies the page being shown.
• Measured on the built site:
  • every fallback URL carries lang="en" on its content and the callout;
  • no translated page carries the callout;
  • axe html-lang-valid and valid-lang are clean on one fallback page and one translated page per locale.
• Screenshots of one fallback page and one translated page in zh-Hans and de, at 1440 and 390.

Surface

• apps/docs/app/[lang]/** layout and page components, root-provider.tsx, lib/i18n.ts (or its equivalent), and the meta/sidebar label files.
• ⛔ No content translation in this card. Translations follow the translation pipeline (The ownership check is inert on main until TRANSLATION_BOT_LOGIN is set #68 / 91 translation fidelity findings on main that the freshness gate passes as current #75).

Order

After the P0 and P1 instruction-fix cards.

Claim: PM loop, repo:objectos seat
Session: session_01FeA1nwBz1ohH65dvffUGKr
Account: hotlong (the seat's linked user, as GET /user answers it; always the card's assignee)
Branch: claude/pm-dispatch-objectos-ju9td1, the session's one designated push branch. #299 is the next PR on it. This card's work is therefore staged: built and verified in its own worktree on a local branch cut from origin/main, then rebased and pushed after #299 lands. Queue change: #298 now goes before #167, because #167 and #299 both edit English frontmatter (titles and descriptions sit on adjacent lines), while #298's surface is disjoint from #299's.
Worktree: objectos-issue-298
Domain: n/a (single-lane repo)
Seat: repo:objectos (objectstack-ai/objectstack#9831)
File surface:

• apps/docs/app/[lang]/** layout and page components;
• apps/docs/app/[lang]/root-provider.tsx;
• apps/docs/lib/i18n.ts or its equivalent;
• the meta/sidebar label files (content/docs/**/meta.*.json), labels only.
  No content translation, and no footer or legal-page metadata (those are Docs metadata: the index share card prints a 511-character description over its title, /privacy and /terms ship no metadata, and an internal MDX note leaks into llms-full.txt and Copy Markdown #299's).
  Stop on breach and explain in the report.
  Container & model: M, mode:subagent, model: default.
  Clause-②: no
  Thread-read: none
  Serial constraints cleared: no. Pushes on this repo are serial on the one branch; the queue is on Author SEO titles for the 42 English pages whose title tag is a single word #167 6010721523, as amended here.

ACCEPT: PR #306 on head 0e5d34852a09c40196ce187f511ee360fa3e0ac7 · 2026-10-06T10:33Z. Landing it now: no governed path is touched, it changes 470 lines (under 5,000), and its checks are green.

Path surface (get_files): 14 files, +446/−24. All of them are app code:

• app/[lang]/docs/[[...slug]]/page.tsx, app/[lang]/docs/layout.tsx, app/[lang]/layout.tsx, root-provider.tsx, components/ai/page-actions.tsx
• the new lib/ui-text.ts, plus lib/ui-text/{de,es,fr,ja,ko,zh-Hans}.json (hand-written) and zh-Hant.json (generated by gen-zh-hant, and covered by its --check)
• scripts/gen-zh-hant.mjs

No content/docs/** file changes, which is why the path-filtered Translations workflow did not run.

Checks on 0e5d348: CI build and Node floor succeeded; Deploy docs was skipped. mergeable_state is clean on base 601bb37.

What it does, as measured by the dev and reviewed by the seat:

• Fallback pages (a locale URL whose page has no source file in that locale):
  • The title, description, body and every TOC entry carry lang="en".
  • A notice in the route's locale sits above the H1. In zh-Hans it reads 「本页尚未翻译，以下显示英文原文。」.
  • Detection reuses translatedLocales() and canonicalLocale(), so it is exact.
  • On the built site, an oracle scan found 323/323 fallback pages and 230/230 translated pages correct, with 0 findings. Inverting the oracle produced 553 findings, so the scan does detect errors.
• Interface text: fumadocs' Translations keys and this app's own controls are localized in all 8 locales. That includes the Privacy and Terms sidebar labels that docs: a short /docs description, legal-page metadata, share cards that fit, no MDX comments in llms bodies #304 added. I checked the screenshots for zh-Hans: 搜索, 本页内容, 复制 Markdown.
• Copy Markdown: it copies the page being shown. A translation copies its own locale's Markdown, inlined at build time (open question A). English pages and fallbacks copy the English .mdx.
• axe: 0 violations on 15 of 15 pages, and valid-lang passes on every fallback page.

Gaps carried, not fixed here:

• fumadocs' hard-coded English accessible names.
• English page-tree names with no lang.
• No zh-Hant 404 copy.
• Open-in-ChatGPT/Claude points at the English .mdx.

These are filed as #305. The sidebar labels that are the titles of untranslated pages belong to the translation pipeline (#68 / #75).
