+**Onboarding Wizard**:
+- First-run wizard collects 5 fields: `job_role`, `industry`, `primary_use_case`, `tone_preference`, `language`. Plus `user_name` derived from profile `name`+`surname`.
+- All fields stored as encrypted core memory (backend `MemoryMiddleware`), not local electron-store.
+- `onboarding_completed_at` on the `users` table (nullable TIMESTAMPTZ) gates the flow — `null` = show wizard, non-null = skip.
+- `AppShell.tsx` gates: if `profile.onboardingCompletedAt == null` → render `<OnboardingFlow>` instead of the app.
+- `auth.status` tRPC procedure auto-seeds `language` and `user_name` into MemoryCore if missing (fire-and-forget `.catch(() => {})`).
+- Format prefs (timezone, dateFormat, timeFormat) are stored in electron-store (`FormatPrefs`), not core memory — they're device-specific.
+- `drizzle-executor.ts` wraps all query results through `formatRow()`/`formatRows()` using the user's FormatPrefs.
+- Settings > Profile section allows post-onboarding editing of all fields + format prefs.
+- **Gotcha — shadcn Button `outline` variant in dark mode**: The variant defines `dark:bg-input/30 dark:border-input dark:hover:bg-input/50` which overrides any custom `className` background. Fix: switch between `variant="default"` and `variant="outline"` instead of adding className overrides.
+- **Gotcha — locale codes vs human names**: `app.getLocale()` and `navigator.language` return codes like `en-US`. Use `Intl.DisplayNames(undefined, { type: 'language' })` to convert to "English". This must be done in both the main process (`locale-defaults.ts`) and renderer (`OnboardingFlow.tsx`).
+
+**i18n (Internationalization)**:
+- Uses `i18next` + `react-i18next` with bundled JSON translations (no lazy loading).
+- Config in `src/renderer/i18n.ts`. 5 languages: EN, IT, ES, FR, DE. `SUPPORTED_LANGUAGES` array exported for UI selectors.
+- Translation files: `src/renderer/locales/{en,it,es,fr,de}/translation.json`. Namespaces: `nav`, `auth`, `tasks`, `settings`, `common`, `errors`, `home`, `timeline`, `projects`, `agents`.
+- **`common.*` namespace** holds shared labels (`save`, `cancel`, `delete`, `edit`, `add`, `rename`, `saving`, `deleting`, `creating`, `renameDescription`, `deleteTitle`). Before adding a new key, check if `common.*` already has it.
+- Pluralization uses i18next `_one`/`_other` suffixes (e.g. `tasksDueToday_one`, `tasksDueToday_other`).
+- `LanguageSync` component in `src/renderer/index.tsx` reads persisted `uiLanguage` from electron-store via tRPC on startup and syncs to i18next.
+- Language selector lives in `GeneralSection.tsx` (Settings > General). On change it: (1) calls `i18n.changeLanguage()`, (2) persists to electron-store via `setUiLanguage` mutation, (3) writes to backend core memory so AI responds in the same language.
+- `getUiLanguage()` exported from `src/main/store.ts` — used by `orchestrator.ts` to append language hint to daily brief prompt.
+- Static data arrays that need translation use `labelKey` pattern (not `label`): store a translation key, call `t(labelKey)` at render time. Used in `NAV_ITEMS`, `COLUMNS`, `SECTIONS`, `SUGGESTION_CHIPS`.
+- When adding new translated text: add the key to **all 5** JSON files. Keep `common.*` keys consistent across all languages.

 **Google OAuth (adiuvAI side)**:
 - `adiuvai://` is NOT accepted by Google as a redirect URI — Google only accepts `http://localhost` or `https://`. The API backend exposes `GET /auth/oauth/google/web-callback` which receives the Google redirect and immediately bounces to `adiuvai://oauth/callback?...`. The redirect URI registered in Google Cloud Console points to the backend, not the Electron app.
 - `app.requestSingleInstanceLock()` is required for the `second-instance` event to fire on Windows/Linux. If it returns `false`, call `app.quit()` immediately (another instance is already running).
@@ -182,6 +208,17 @@ FastAPI app (app/main.py)
 - **CORS includes `app://`**: Electron uses custom `app://` protocol, not http/https
 - **Vector search on encrypted data is not semantic**: Backend derives deterministic 32-dim floats from blob SHA-256 for storage/search — a known trade-off
 
+**Onboarding (API side)**:
+- `PUT /auth/me/memory` — updates core memory k/v pairs and optionally marks onboarding complete (`mark_onboarded: true` sets `users.onboarding_completed_at`).
+- `POST /auth/me/onboarding/reset` — nullifies `onboarding_completed_at` so the wizard re-runs.
+- `POST /auth/onboarding/normalize` — LLM-normalizes free-text onboarding inputs via `gpt-4o-mini`; returns inputs unchanged on error.
+- `get_current_user()` in `auth.py` middleware now decrypts core memory blocks and includes them in `UserProfile.memory` dict.
+- `users.onboarding_completed_at` is a nullable TIMESTAMPTZ column — returned as epoch ms (int) in UserProfile schema.
+
+**i18n (API side)**:
+- `_language_instruction()` in `app/core/deep_agent.py` reads the user's `language` from `MemoryCore` and appends a system prompt directive ("Always respond in {language}") to all 4 `run_*` functions.
+- The Electron client writes the user's chosen language to backend core memory on language change, so the API picks it up on the next agent call.
+
 **Google OAuth (api side)**:
 - OAuth routes live in `app/api/routes/auth.py`: `GET /auth/oauth/{provider}/authorize`, `POST /auth/oauth/{provider}/callback`, `GET /auth/oauth/{provider}/web-callback` (bounces to deep link, excluded from OpenAPI schema).
 - Provider abstraction in `app/auth/oauth_providers.py` — `GoogleOAuthProvider` uses `httpx` directly (no `authlib`). PKCE S256 is implemented manually via `generate_pkce_pair()`.
