+# Android Companion App
+
+The Android companion app lives in a separate repository at `/home/bvandeusen/Nextcloud/Projects/fabled_app`.
+
+## Stack
+
+- Flutter + Dart
+- Riverpod (state management)
+- GoRouter (navigation)
+- Dio (HTTP client)
+- PersistCookieJar (session persistence)
+- SSE streaming via `fetch` + `ReadableStream` bridge
+
+## Architecture
+
+```
+lib/
+  app.dart                          # GoRouter + _Shell + _QuickCaptureBar
+  core/constants.dart               # Routes.*
+  data/
+    models/                         # note.dart, task.dart, project.dart
+    api/                            # notes_api.dart, tasks_api.dart, projects_api.dart
+    repositories/                   # notes, tasks, projects repositories
+  providers/
+    api_client_provider.dart        # all API + repository providers
+    notes_provider.dart             # NotesNotifier
+    tasks_provider.dart             # TasksNotifier
+    projects_provider.dart          # ProjectsNotifier
+  screens/
+    notes/note_edit_screen.dart     # chip tag input + ProjectSelector
+    tasks/task_edit_screen.dart     # ProjectSelector
+    projects/project_list_screen.dart
+  widgets/
+    project_selector.dart           # reusable DropdownButtonFormField
+```
+
+## Navigation
+
+4-tab shell (Notes · Tasks · Projects · Chat):
+- Phone: bottom `NavigationBar`
+- Tablet/landscape: `NavigationRail`
+
+Quick Capture bar persists across all tabs. Settings accessible from top-right icon.
+
+## Feature Status
+
+| Feature | Status | Notes |
+|---------|--------|-------|
+| Notes CRUD | ✅ | Tags chip input; project selector in editor |
+| Tasks CRUD | ✅ | Project selector in editor |
+| Projects list | ✅ | Active/archived sections; long-press status change; create dialog |
+| Chat + SSE | ✅ | Full streaming |
+| Quick Capture | ✅ | Offline queue with retry |
+| Tags | ✅ | Chip input in NoteEditScreen; typed as `List<String>` |
+| Project assignment | ✅ | `ProjectSelector` dropdown in Note + Task editors |
+| Milestones | ❌ deferred | Too granular for mobile; web UI handles it |
+| Push notifications | ❌ incompatible | Backend uses browser VAPID; Flutter needs FCM/APNs — separate implementation required |
+| CalDAV settings | ❌ intentional | Server-side config only; not exposed in mobile app |
+
+## API Compatibility Notes
+
+- `GET /api/projects/:id` returns a flat JSON object (not `{project: ...}` wrapper); includes `summary` field.
+- `POST /api/projects` returns the project dict directly (201).
+- `PATCH /api/projects/:id` returns the updated project dict.
+- Task body field is `body` (not `description`) — the app maps `description` → `body` on serialize.
+
+## Self-Update
+
+The app supports self-update via the Forgejo release API (`update_provider.dart`). It checks the latest release tag and prompts the user to download and install a new APK when one is available.
+
+## CI
+
+Builds are triggered from the Forgejo Actions pipeline in the `fabled_app` repository. The APK is attached to the release as a downloadable artifact.

+## LLM Chat — Internal Pipeline
+
+### Intent Routing
+
+Before the main model runs, a lightweight intent classifier (`services/intent.py`) runs concurrently with `build_context()`. It makes a fast non-streaming call (~400ms) using a smaller dedicated model (`OLLAMA_INTENT_MODEL`, default `qwen2.5:7b`) to determine if the message requires a tool call.
+
+**Skip heuristic** — Intent classification is skipped entirely for short messages (≤10 words) with no action/object keywords, saving 400–800ms on conversational replies.
+
+**Prior-work fast-path** — Phrases like "research you did", "note you made", "using your research" skip the LLM call entirely and route to null (chat), preventing `search_web` from firing when the user references existing notes.
+
+If a tool is detected, the intent's one-sentence `ack` field is streamed as the first chunk (becoming time-to-first-token), then the tool executes, then the main model generates a follow-up response with the tool result.
+
+### Tool Loop
+
+Multi-round tool loop (max 5 rounds). All tool implementations are in `services/tools.py` with `execute_tool()` as the dispatcher.
+
+**Duplicate protection on create_note / create_task:**
+1. Exact title match (case-insensitive) → hard block, redirect to `update_note`
+2. Fuzzy title match (SequenceMatcher ≥ 82%; punctuation stripped before candidate search) → hard block
+3. Semantic content similarity (`semantic_search_notes` threshold 0.90, body ≥ 200 chars) → soft block with `requires_confirmation: true`
+
+**Project resolution** (`_resolve_project`): 4-step lookup — (1) exact DB match, (2) `query in title` substring, (3) `title in query` reverse substring, (4) SequenceMatcher ≥ 0.55.
+
+### Model Status
+
+Three states returned by `GET /api/chat/status`:
+- `not_found` — model not installed; orange indicator in header
+- `cold` — installed but not loaded in VRAM; yellow pulsing indicator (first request will be slow)
+- `loaded` — hot in VRAM; green indicator
+
+After `warmModel()` is called, a 5s polling loop runs for up to 60s until the indicator turns green.
+
+### Context Window
+
+`OLLAMA_NUM_CTX` (default 16384) controls the context window for all generation calls. Intent classification always uses `num_ctx=4096` to reduce VRAM pressure. History summarisation kicks in at 30 messages, keeps 8 recent, summary max 400 tokens.
+
+### Image Search
+
+`search_images` tool (SearXNG `categories=images`) fetches images server-side, stores on disk (SHA-256 dedup, 5 MB cap), and serves from `/api/images/<id>` — the user's browser never contacts the original image host. Requires `SEARXNG_URL`.
+
+### Web Research Pipeline
+
+Triggered by "research X and make a note" or the Research button in ChatView:
+1. Intent model generates 5 focused sub-queries as a JSON array
+2. All 5 SearXNG queries run in parallel (200ms stagger)
+3. Up to 15 unique URLs fetched in parallel
+4. Up to 12 sources passed to synthesis LLM (`num_ctx=16384`, `num_predict=8192`)
+5. Note created with `tags=["research"]`
+
+SearXNG tip: add the app server IP to `botdetection.ip_lists.pass_ip` in SearXNG `settings.yml` to bypass the rate limiter for backend requests.
+
+## Roadmap
+
+- Calendar/timeline view for tasks with due dates
+- Email integration (read/send via IMAP/SMTP tools in chat)
+- Session invalidation on user deletion
+- Flutter push notifications (requires FCM/APNs — separate from web VAPID)
+- Flutter milestone support in project view
+
