# AGENTS.md

## Stack
- **Frontend**: Vue 3 + TypeScript + Vite (port 5173)
- **Desktop**: Tauri 2 (Rust backend in `src-tauri/`)
- **Runtime**: Node.js + npm + Rust/Cargo all required

## Commands
```
npm run dev          # Vite dev server (port 5173)
npm run build        # vue-tsc --noEmit && vite build (typecheck + bundle)
npm run preview      # Preview production build
npm run tauri        # Alias for `cargo tauri`
cargo tauri dev      # Full Tauri desktop dev (builds frontend + opens native window)
cargo tauri build    # Full native app build (outputs to src-tauri/target/release/bundle/)
```

## Architecture
- **Dual-mode API**: Frontend uses `apiCall()` from `src/api/index.ts` which detects `window.__TAURI__` and dispatches to either Tauri IPC (`invoke`) or HTTP to proxy at `http://0.0.0.0:8888`.
- **Rust Tauri commands**: `src-tauri/src/main.rs` — 22 Tauri commands:
  - Core API: `search_llm_smart`, `search_agents`, `get_files`, `get_people`, `get_faces`, `get_traces`, `get_file_info`
  - Media: `get_thumbnail`, `get_face_thumbnail`, `get_identity_profile`
  - Identity: `update_identity_name`, `update_identity_status`, `update_identity_starred`, `delete_identity`, `search_identities`, `get_face_candidates`, `merge_identities`, `bind_face`, `unbind_face`
  - File ops: `register_file`, `process_file`, `unregister_file`
  - Local SQLite: `get_search_history`, `save_search_history`, `rename_search_history`, `pin_search_history`, `delete_search_history`, `get_bookmarks`, `save_bookmark`, `delete_bookmark`
- **Rust HTTP proxy** (`src-tauri/src/proxy.rs`): Axum on port 8888. Forwards `/api/v1/*` to Core API (localhost:3002) with API key injection. Handles `/api/v1/search-history` and `/api/v1/bookmarks` locally via `db::` functions. Handles `/api/v1/identity/{uuid}/profile` (reads local filesystem) and `/api/v1/face-thumbnail` (downloads frame + crops bbox) locally — these mirror the Tauri IPC commands that can't be proxied to Core API.
- **Per-user SQLite**: `src-tauri/src/db.rs` — Project-root `data/users/demo.sqlite` (outside `src-tauri/` to avoid dev watcher rebuilds). WAL mode enabled. Tables: `search_history`, `bookmarks`, `app_users`. `init_db()` called on app setup.
- **Frontend routes**: `/search`, `/library`, `/people` (redirect `/` → `/search`)
- **Frontend entry**: `src/main.ts` → `App.vue` → `router/index.ts`
- **Global directive**: `v-observe` registered in `main.ts` from `src/directives/vObserve.ts`
- **Composables**: `src/composables/useSearchHistory.ts` — `useSearchHistory()` and `useBookmarks()` for SQLite-backed search history and bookmarks CRUD via `apiCall`.

## Key Details
- **`withGlobalTauri: true`** in `tauri.conf.json` — `window.__TAURI__` is available in the webview.
- **No linter, formatter, or tests configured** — do not invent them unless asked.
- **TypeScript is non-strict** (`strict: false` in `tsconfig.json`).
- **CI/CD**: Shell scripts only (`ci-cd.sh`, `local-ci-cd.sh`, `setup-gitea-ci.sh`). No GitHub Actions.
- **Full native build order**: `npm install` → `npm run build` → `cargo tauri build`
- **Rust deps**: sqlx 0.8, rusqlite 0.32 (bundled), reqwest, tokio, tauri-plugin-shell, base64, chrono, uuid
- **Core API**: `http://localhost:3002`, API key hardcoded in Rust only.
- **Proxy**: `http://0.0.0.0:8888` — forwards `/api/v1/*` to Core API with auto-injected key; handles `/api/v1/search-history` and `/api/v1/bookmarks` locally.

## Patterns
- **Search thumbnails**: Use `start_frame` for frame-accurate thumbnails. Cache key format: `${file_uuid}:${start_frame}`. Not a single `file_uuid` key because same file can appear in multiple search results at different time segments.
- **Store thumbnail queue**: `src/store.ts` provides `loadThumbnail()`, `loadFaceThumb()`, `loadProfile()` with max 4 concurrent requests. Always use store functions for shared data across pages.
- **Page perPage limit**: Core API hangs on `per_page >= 100`. Always use `perPage ≤ 20`. The Rust `get_people` command uses a special 2-page × 100 flow (separate from frontend).
- **PersonDetailView**: Uses `ensurePeople()` from store instead of direct `get_people` call. Face thumbnails go through store's `loadFaceThumb()`. Faces/candidates use `perPage: 20`.
- **v-observe directive**: Global directive (`v-observe`) registered in `main.ts`. Defined in `src/directives/vObserve.ts`. Uses `IntersectionObserver` with 200px rootMargin. Includes `requestAnimationFrame` fallback for elements already visible on mount.
- **SearchView empty state**: When `messages.length === 0`, shows `.ms-hero` with "Momentry Studio" + "Turn Every Moment Into Intelligence" slogan. Chat area gets `.chat--empty` class (flex-column, justify-end) to position hero near the search bar. Once messages exist, hero disappears and `.ibar` stays fixed at bottom.
- **No `console.log` in *.vue files**: All debug console.log statements have been removed. Use `console.error` only for actual errors.
- **Search history & bookmarks**: Stored in per-user SQLite (`data/users/demo.sqlite`), not localStorage. History items have `id`, `query`, `title`, `chat_state` (JSON-serialized Vue messages), `mode`, `pinned`, timestamps. Max 30 items; pinned sorted first. Composable `useSearchHistory()` provides `loadHistory`, `saveToHistory`, `renameHistory`, `pinHistory`, `deleteHistory`, `restoreFromHistory`. Composable `useBookmarks()` provides `loadBookmarks`, `saveBookmark`, `deleteBookmark`.
- **SearchView history panel**: Dropdown with ⋯ menu per item (Pin/Unpin, Rename, Delete). +New button clears chat. Click item → restores `chat_state` JSON or runs new search. Renames via modal dialog.
- **SearchView bookmark panel**: Dropdown with items from SQLite. Click → runs search. Hover shows x button to delete.
- **API call snake_case**: Frontend `apiCall()` sends `camelCase` args to Tauri IPC (auto-converted by Tauri) but `snake_case` in HTTP body. `buildHttpRequest()` converts arg names for HTTP mode (e.g., `chatState` → `chat_state`).
- **HistoryItem ID format**: `h_{timestamp}_{random}` e.g. `h_1718000000_abc123`.
- **SQLite WAL mode + path outside src-tauri**: Database at project-root `data/users/demo.sqlite` (not inside `src-tauri/`). WAL journal mode prevents `-journal` file creation that triggers `cargo tauri dev` watcher rebuilds. Default path `../data/users/demo.sqlite` resolved from `src-tauri/` cwd.
- **Video streaming**: `get_video_stream` is NOT a Tauri command. Both Tauri and browser modes use the proxy URL directly (`http://localhost:8888/api/v1/file/{uuid}/video?...`). The `<video>` element streams from the proxy, never via IPC. Proxy streams `video/*` and `octet-stream` responses (doesn't buffer entire body).
- **Face thumbnail & identity profile in browser mode**: `/api/v1/face-thumbnail` and `/api/v1/identity/{uuid}/profile` are handled locally by the proxy (same logic as Tauri IPC commands). Core API doesn't support bbox cropping for face thumbnails or local filesystem for profiles.
