   - What RN does: `AboutDataSettings.tsx:61-66,226-244` keeps toggles in `useState` with categories (`sync`, `render`) that exist nowhere; the "Debug" tab is `implemented: false` (`SettingsScreen.tsx:111`); code uses raw `console.warn`.
   - Fix hint: persist `debugMode`/`debugCategories`, add `src/lib/debug.ts` mirroring WEB's category API, route the `[push]`, `[settings-store]`, `[updates-store]` warnings through it, and drop the dead Debug tab or implement a log viewer.
 
-- [ ] **Settings panes are hard-coded English (no i18n)** — `P2` — `partial`
+- [x] **Settings panes are hard-coded English (no i18n)** — fixed in 22697fd — `P2` — `partial` — all panes I own use t(); RN-only keys harvested into locales/rn/en.json (npm run i18n:harvest); Calendar/Contacts/ContentSenders/Filter/Vacation/Files/Folder panes belong to other agents
   - What WEB does: every settings component uses `useTranslations` with keys in `locales/*/common.json`.
   - What RN does: only `LanguageSettings.tsx` and `FilterSettings.tsx` call `t()`; the other 24 settings components plus `settings-section.tsx` have literal English strings (grep count 0 for `t(` in each). `SettingsScreen.tsx:184-187` translates group/tab labels only, and the "Experimental"/"Not implemented"/"Unavailable" badges (`:297,270-273`) are literal.
   - Fix hint: the vendored catalog already contains `settings.*` keys for almost every label (WEB keys); wrap each label/description in `t('settings.<tab>.<key>', 'fallback')`.

+- [x] **Settings tabs shown regardless of server capability / admin policy** — fixed in 3ffcef2 — `P3` — `partial` — Sieve/Vacation gating via useHasSieve/useHasVacation (filters agent's commit)
   - What WEB does: hides Vacation/Filters when Sieve is absent, Templates/Keywords/Sidebar apps/Plugins/Themes/Debug behind admin feature flags, Security behind Stalwart features (`components/settings/settings-app.tsx:724-766`); settings can be `locked`/hidden per policy (`appearance-settings.tsx:89-119`).
   - What RN does: hides only calendar/contacts/files by capability and updates by platform (`RN: SettingsScreen.tsx:142-179`); Vacation and Filters render even without Sieve; `SettingItem` has a `locked` prop (`settings-section.tsx:68-86`) that nothing sets. Admin policy is N/A (no webmail server), but Sieve gating is not.
   - Fix hint: gate `vacation`/`filters` on `CAPABILITIES.SIEVE` in the session like WEB's `supportsSieve`/`supportsVacation`.

   - What RN does: `RN: locales/en/common.json` last synced 2026-07-22 has 2336 keys; 640 WEB keys are absent; RN en carries 17 keys WEB lacks (hand-added `email_composer.*`) which the 14 other RN locales do not have (de/fr/ja each miss the same 16 keys), and 19 keys RN code calls (`email_composer.schedule_*`, `email_list.no_*_folder`) exist in no catalog, so the inline fallback always shows in every language.
   - Fix hint: make `sync-locales.mjs` merge instead of overwrite (keep RN-only keys under a separate `locales/rn/<lang>.json` overlay), add a key-parity test like WEB's translation coverage test, and run it in CI.

   - What WEB does: next-intl ICU messages (`{count, plural, ...}`, `{name}` args).
   - What RN does: plain nested lookup returning the raw string (`RN: src/i18n/index.ts:54-71`); any WEB string with `{placeholder}` renders literally, and plurals are hand-rolled English (`OfflineBanner.tsx:22`, `AboutDataSettings.tsx:96,176,190`, `LayoutSettings.tsx:148-149`).
   - Fix hint: add `t(key, fallback, params)` with `{name}` substitution and a minimal ICU plural (`intl-messageformat` is small and works on Hermes), then replace the hand-rolled plurals.

   - What WEB does: preview uses tokens (`components/settings/appearance-settings.tsx:21-64`).
   - What RN does: `AppearanceSettings.tsx:63` paints read subjects `rgba(250,250,250,0.8)` and `:193` preview text `rgba(161,161,170,0.7)` regardless of theme, so the preview is near-invisible on light.

   - What RN does: `RN: app.config.js:33` sets `userInterfaceStyle: 'dark'`, which prebuild writes as `UIUserInterfaceStyle = Dark` in Info.plist, so `useColorScheme()` (`src/theme/colors.ts:16`, `App.tsx:220`) always returns `dark` and "System" behaves like "Dark". On Android without `expo-system-ui` (not in `package.json`) the key is ignored with a prebuild warning, so Android is probably fine. Splash background is also dark-only (`:38`).
   - Fix hint: set `userInterfaceStyle: 'automatic'` and give the splash a light variant (`splash.dark`).

   - Fix hint: minimal viable subset = map WEB's built-in theme token sets (`builtin-themes.ts` light/dark `colors`) onto `ThemePalette` and let `useColors()` pick `activeThemeId`; remove the upload button. Otherwise hide the tab.

   - What WEB does: apps render in the navigation rail (`components/layout/navigation-rail.tsx:391` filters `showOnMobile`), inline iframe or new tab, `keepAppsLoaded`, drag reorder, plus operator-pinned apps merged from policy (`lib/sidebar-apps.ts:103-112`, commit 4fe5701b).
