+# i18n migration tracking
+
+Working doc for the incremental UI-string translation effort. The i18n **mechanism**
+is done; this tracks moving the app's remaining hardcoded strings into the translation
+files, one batch at a time. Tick boxes as views are converted.
+
+- **Engine:** hand-rolled, zero-dependency. `src/lib/i18n/index.svelte.ts`
+- **Baseline dictionary:** `src/lib/i18n/en.json` (English is the source-of-truth key set
+  **and** the fallback for any missing key)
+- **Selector:** Settings → Language (`section === "language"`)
+- **Scope decision:** display language is separate from the transcription `whisper_language`
+  setting — don't conflate them.
+
+## How to convert a string (the pattern)
+
+1. Add a key to `en.json`. Naming: `<area>.<subarea>.<name>`, dotted, grouped by view —
+   e.g. `nav.recording`, `settings.transcription.title`, `meetings.empty`.
+2. Replace the literal in markup with `{t("key")}` (import `t` from `../i18n/index.svelte`).
+3. Dynamic bits use placeholders: `t("meetings.count", { n })` against
+   `"meetings.count": "{n} meetings"`. Handle plurals with a caller-side ternary for now
+   (`n === 1 ? t("...one") : t("...many")`) — the engine is intentionally simple.
+4. Attributes translate the same way: `title={t("...")}`, `aria-label={t("...")}`,
+   `placeholder={t("...")}`.
+5. `npm run check` must stay at 0 errors/warnings.
+
+> When adding a **new language** (not covered by this doc's batches): copy `en.json` to
+> `<code>.json`, translate it, and register it in `DICTS` + `LOCALES` in
+> `index.svelte.ts`. That one file is the whole job.
+
+## Done
+
+- [x] i18n engine + `en.json` baseline + Settings language selector (branch
+      `feature_chore_bug_007`)
+- [x] `Settings.svelte` — nav labels (`nav.*`), the Language section
+      (`settings.language.*`), and the Transcription Language section
+      (`settings.transcription.*`)
+
+Current key count in `en.json`: **18** (`nav.*`, `settings.language.*`,
+`settings.transcription.*`).
+
+## Outstanding — suggested batches
+
+Ordered roughly by user-visibility ÷ effort. Sizes are rough (line count / labeled
+attributes) to help portion the work, not exact string counts. A file isn't "done" until
+its visible text **and** its `title`/`aria-label`/`placeholder` attributes are keyed.
+
+### Batch A — app shell (high visibility, medium size)
+- [ ] `src/App.svelte` (~846 lines, ~21 labeled attrs) — top nav, window/tray strings,
+      dialog prompts, empty states. Prefix `app.*`.
+
+### Batch B — meetings list (small, high traffic)
+- [ ] `src/lib/views/MeetingsList.svelte` (~373 lines, ~9 attrs) — list headers, empty
+      state, search/filter placeholders, date/tag labels. Prefix `meetings.*`.
+
+### Batch C — transcript & notes (large surface)
+- [ ] `src/lib/views/TranscriptNotes.svelte` (~869 lines, ~40 attrs) — export button
+      labels, editor toolbar tooltips, reprocess controls, pane toggles, empty states.
+      Prefix `transcript.*` / `notes.*`. (Timestamps + the Obsidian/Bundle button labels
+      live here.)
+
+### Batch D — summary panel (medium)
+- [ ] `src/lib/views/SummaryPanel.svelte` (~1335 lines, ~14 attrs) — summary/action-item
+      UI, participants, recording playback labels, LLM status copy. Prefix `summary.*`.
+
+### Batch E — Settings, remaining sections (largest; split further as needed)
+The file is big — do it section by section, one sub-batch each:
+- [ ] Recording (`section === "recording"`) — prefix `settings.recording.*`
+- [ ] Hardware (`section === "hardware"`, excluding the already-done Transcription Language)
+- [ ] Storage (incl. the Export/Import copy) — `settings.storage.*`
+- [ ] Calendar — `settings.calendar.*`
+- [ ] Sync — `settings.sync.*`
+- [ ] AI — `settings.ai.*`
+- [ ] MCP server — `settings.mcp.*`
+- [ ] Privacy — `settings.privacy.*`
+- [ ] About — `settings.about.*`
+
+### Batch F — components
+- [ ] `ConsentNotice.svelte` (~72 lines) — **legal/consent copy; translate carefully**
+- [ ] `HostedAiBanner.svelte` (~93 lines) — third-party-egress disclosure copy
+- [ ] `ImportMeeting.svelte` (~229 lines, ~5 attrs) — import dialog
+- [ ] `ThemeToggle.svelte` (~72 lines) — one aria-label
+- [ ] `TagChip.svelte`, `LevelMeter.svelte`, `Splitter.svelte` — check for any stray
+      user-facing strings (likely minimal)
+
+## Not translated (intentional)
+
+- Backend / Rust error messages surfaced via `WaError` — out of scope for the frontend
+  `t()`; revisit only if we localize command errors.
+- Provider/proper names (Ollama, Anthropic, OpenAI, Obsidian, WebDAV, WhispAssist),
+  model ids, ISO language codes.
+- Console/`tracing` logs.
