+# Localization
+
+English UI copy stays beside the component that renders it:
+
+```tsx
+const t = useTranslate()
+t('viewer.camera.topView', 'Top view')
+```
+
+The in-code text is the fallback and source of truth. Scene data, exports,
+catalog content, MCP/agent text, and developer errors are not translated.
+
+## Add or adapt a language
+
+1. Run `bun run i18n:extract` after adding or changing `t()` calls.
+2. Add a catalog in `packages/editor/src/i18n/catalogs/<locale>.json`, or run
+   `bun run i18n:translate -- <locale>` for an existing bundled locale.
+3. Review every translation in context. The AI command only prepares a diff;
+   it never runs in the app or CI.
+4. Add the locale to `packages/editor/src/i18n/locales.ts` when it should ship
+   with the editor.
+5. Run `bun run i18n:check`.
+
+Each translation records the hash of its English source. Changing the English
+message makes the translation stale until a person updates or approves it.
+`i18n:check` also rejects missing keys and changed placeholders.
+
+To adapt a bundled pack without forking, register an override after it:
+
+```ts
+import { registerMessages, setLocale } from '@pascal-app/core/i18n'
+import { registerBundledLocales } from '@pascal-app/editor/locales'
+
+registerBundledLocales()
+registerMessages('fr', 'viewer', {
+  'camera.topView': 'Vue en plan',
+})
+setLocale('fr')
+```
+
+Later registrations win. Regional fallback is automatic (`pt-BR` → `pt` →
+the English literal). An embedding host can set the locale before mount, pass
+`<Editor locale="fr" />`, or use `?lang=fr` in the standalone app and iframe.
+Calling `setLocale` later switches the mounted UI.
+
+Community packs use the same `registerMessages(locale, namespace, messages)`
+contract. Keep namespaces with their owner: `core.*`, `viewer.*`, `editor.*`,
+`node.<kind>.*`, or `plugin.<id>.*`.
+
+## AI-assisted fill
+
+`bun run i18n:translate -- fr` refreshes only missing or stale entries. Set:
+
+- `I18N_PROVIDER=openai`, `OPENAI_API_KEY`, and `I18N_MODEL`; or
+- `I18N_PROVIDER=anthropic`, `ANTHROPIC_API_KEY`, and `I18N_MODEL`.
+
+`OPENAI_BASE_URL` and `ANTHROPIC_BASE_URL` are optional. The command sends the
+English copy, source context, and `i18n/glossary.json` to the selected provider,
+validates placeholders, and writes JSON only. API keys are never required by
+`i18n:check` and must not be committed. Human review remains mandatory,
+especially for architecture/CAD terminology and short controls.

 # Localization
 
-English UI copy stays beside the component that renders it:
+> The localization API is experimental and unreleased. Its signatures may
+> change before the first i18n-capable package release.
+
+Pascal uses Lingui 6 for ICU MessageFormat, React updates, extraction, and
+catalog compilation. A thin Pascal registry keeps the ownership contract that
+an embeddable editor needs: namespaced host and plugin packs, ordered
+overrides, locale fallback, isolated request/editor scopes, and locale-aware
+number formatting.
+
+Published packages use Lingui’s plain runtime call form, not macros:
 
 ```tsx
-const t = useTranslate()
-t('viewer.camera.topView', 'Top view')
+const i18n = usePascalI18n()
+
+i18n._({
+  id: 'viewer.camera.topView',
+  message: 'Top view',
+})
 ```
 
-The in-code text is the fallback and source of truth. Scene data, exports,
-catalog content, MCP/agent text, and developer errors are not translated.
+Hosts therefore need no Lingui compiler plugin or extra transform. English UI
+copy stays beside the component that renders it and is also compiled into the
+bundled English catalog. Scene data, exports, catalog content, MCP/agent text,
+and developer errors are not translated.
+
+## Catalogs
 
-## Add or adapt a language
+The source and translated catalogs are PO files under
+`packages/editor/src/i18n/locales/<locale>/messages.po`. Compiled TypeScript
+catalogs next to them are what the browser loads; PO files and the ICU compiler
+are not part of the normal rendering path.
 
-1. Run `bun run i18n:extract` after adding or changing `t()` calls.
-2. Add a catalog in `packages/editor/src/i18n/catalogs/<locale>.json`, or run
-   `bun run i18n:translate -- <locale>` for an existing bundled locale.
-3. Review every translation in context. The AI command only prepares a diff;
-   it never runs in the app or CI.
-4. Add the locale to `packages/editor/src/i18n/locales.ts` when it should ship
-   with the editor.
-5. Run `bun run i18n:check`.
+After adding or changing a runtime message:
 
-Each translation records the hash of its English source. Changing the English
-message makes the translation stale until a person updates or approves it.
-`i18n:check` also rejects missing keys and changed placeholders.
+1. Run `bun run i18n:extract`. Lingui updates the PO catalogs and compiled
+   modules.
+2. Translate every new entry in each bundled locale.
+3. Keep the `Source-Hash` comment in sync and mark a reviewed entry
+   `Review: human` without the `fuzzy` flag.
+4. Review the copy in context, then run `bun run i18n:check`.
 
-To adapt a bundled pack without forking, register an override after it:
+`i18n:check` needs no API key. It fails for extraction/compiled-catalog drift,
+missing or stale translations, unreviewed entries, malformed ICU, changed
+placeholders or tags, invalid target-locale plural branches, and glossary
+violations. It only warns when a new literal bypasses Lingui on the converted
+viewer/build-panel surfaces.
+
+`bun run i18n:compile` runs Lingui’s strict compiler directly when only the
+generated runtime catalogs need refreshing.
+
+To bundle another language, add its locale to `lingui.config.ts` and
+`packages/editor/src/i18n/locales.ts`, extract, translate, compile, and add it
+to the locale-pack test.
+
+## Hosts, plugins, and overrides
+
+Keep namespaces with their owner: `core.*`, `viewer.*`, `editor.*`,
+`node.<kind>.*`, or `plugin.<id>.*`. Raw community and host packs use ICU
+strings and are compiled atomically through the lazy authoring path:
 
 ```ts
 import { registerMessages, setLocale } from '@pascal-app/core/i18n'
 import { registerBundledLocales } from '@pascal-app/editor/locales'
 
 registerBundledLocales()
-registerMessages('fr', 'viewer', {
+
+await registerMessages('fr', 'viewer', {
   'camera.topView': 'Vue en plan',
 })
+await registerMessages('en', 'viewer', {
+  'camera.topView': 'Plan view',
+})
+
 setLocale('fr')
 ```
 
-Later registrations win. Regional fallback is automatic (`pt-BR` → `pt` →
-the English literal). An embedding host can set the locale before mount, pass
-`<Editor locale="fr" />`, or use `?lang=fr` in the standalone app and iframe.
-Calling `setLocale` later switches the mounted UI.
+Later registrations win, including English overrides. Regional fallback is
+automatic (`pt-BR` → `pt` → the English literal), while Simplified Chinese
+script tags can use the `zh-CN` pack without crossing into Traditional Chinese.
+
+Pack authors that already compile with Lingui may call the synchronous
+`registerCompiledMessages(locale, namespace, messages)` instead. Raw
+`registerMessages` is intentionally asynchronous because it loads the ICU
+compiler only for that authoring/host path.
 
-Community packs use the same `registerMessages(locale, namespace, messages)`
-contract. Keep namespaces with their owner: `core.*`, `viewer.*`, `editor.*`,
-`node.<kind>.*`, or `plugin.<id>.*`.
+For server rendering, create one isolated scope per request and render the same
+scope on the client:
+
+```tsx
+const i18n = createI18n({ locale: requestedLocale })
+
+return <PascalI18nProvider i18n={i18n}>{children}</PascalI18nProvider>
+```
+
+The standalone app resolves `?lang=` in its request proxy, so localized text
+and numbers are present in the server response and match hydration.
+`<Editor locale="fr" />` creates the same kind of isolated scope for embeds.
+Unscoped editors follow the default `setLocale`; scoped hosts switch at runtime
+with `i18n.setLocale(...)`.
 
 ## AI-assisted fill
 
-`bun run i18n:translate -- fr` refreshes only missing or stale entries. Set:
+`bun run i18n:translate -- fr` sends only missing or source-stale PO entries
+through the Vercel AI SDK. Configure one provider and model:
 
 - `I18N_PROVIDER=openai`, `OPENAI_API_KEY`, and `I18N_MODEL`; or
 - `I18N_PROVIDER=anthropic`, `ANTHROPIC_API_KEY`, and `I18N_MODEL`.
 
-`OPENAI_BASE_URL` and `ANTHROPIC_BASE_URL` are optional. The command sends the
-English copy, source context, and `i18n/glossary.json` to the selected provider,
-validates placeholders, and writes JSON only. API keys are never required by
-`i18n:check` and must not be committed. Human review remains mandatory,
-especially for architecture/CAD terminology and short controls.
+`OPENAI_BASE_URL` and `ANTHROPIC_BASE_URL` are optional. The structured-output
+request includes the English ICU source, source locations, and
+`i18n/glossary.json`. Every returned ID, ICU message, placeholder, tag, plural
+branch, and applicable glossary term is validated before any PO file is
+written.
+
+AI output is always marked `fuzzy`, `Review: required`, and records provider,
+model, and review notes. It never becomes a shipping translation until a human
+reviews it, removes `fuzzy`, and changes the review marker to `human`.
+Translation never runs in the app or ordinary CI, and API keys must not be
+committed.
