+
+## Project Overview
+
+LinkSyncExtension is a Firefox browser extension that synchronizes bookmarks with LinkSyncServer. It provides a popup UI for managing bookmarks, collections, and queries, with a background script handling automatic synchronization.
+
+## Architecture
+
+```

+├── manifest.json          # Firefox extension manifest v2

+
+## Communication Pattern
+
+```
+popup.js/options.js ──browser.runtime.sendMessage──> background.js
+background.js ────────────────────────────────────> API (LinkSyncServer)
+background.js ──browser.bookmarks.*───────────────> Firefox bookmarks
+content.js ─────browser.runtime.onMessage─────────> popup.js
+```
+
+All API calls go through `utils/api.js`. The popup sends messages to the background script, which handles the actual API communication. This keeps the API token in the background context.
+
+## Key Modules
+
+### utils/api.js
+- `API.init()` - loads settings from storage
+- `API.request(method, path, body)` - core request with retries (3x), timeout (10s), rate limit handling
+- `API.login(username, password)` - authenticates and stores token
+- `API.testConnection()` - hits /health endpoint
+- CRUD methods for links, collections, queries, sync
+
+### utils/sync.js
+- `SyncEngine.runSync()` - main sync entry point
+- Three modes: bi-directional, browser-authoritative, server-authoritative
+- `SyncEngine.detectConflicts()` - finds title mismatches between browser and server
+- Uses `browser.bookmarks.getTree()` for local bookmarks
+
+### utils/query-engine.js
+- `QueryEngine.tokenize(expression)` - lexer
+- `QueryEngine.parse(expression)` - recursive descent parser
+- `QueryEngine.validate(expression)` - returns {valid, ast} or {valid, error}
+- Supports: TERM, TERM_SET, FIELD (url/tag/title/description/path/id), AND, OR, XOR, parentheses
+
+### background.js
+- Listens for `browser.runtime.onMessage` from popup/options
+- Handles bookmark change events (`onCreated`, `onChanged`, `onRemoved`)
+- Auto-sync timer (5 min interval when enabled)
+- Message types: SYNC_NOW, GET_SETTINGS, SAVE_SETTINGS, TEST_CONNECTION, LOGIN, GET_BOOKMARKS, CREATE_BOOKMARK, UPDATE_BOOKMARK, DELETE_BOOKMARK, GET_COLLECTIONS, EXECUTE_QUERY, PARSE_QUERY
+
+### popup.js
+- Tabbed interface: Bookmarks, Collections, Query
+- Settings modal (server URL, API key, sync mode, deletions, auto-sync)
+- Toast notifications (success/error/info, auto-dismiss after 3s)
+- Bookmark form with auto-fill from current tab
+- Search filter for bookmarks
+- Query builder with parse/execute buttons
+
+## Storage Keys
+
+| Key | Type | Description |
+|-----|------|-------------|
+| `linksync_server_url` | string | Server base URL |
+| `linksync_api_key` | string | JWT bearer token |
+| `linksync_sync_mode` | string | bi-directional / browser-authoritative / server-authoritative |
+| `linksync_deletions` | boolean | Enable deletions during sync |
+| `linksync_auto_sync` | boolean | Enable 5-minute auto-sync |
+| `linksync_last_sync` | string | ISO timestamp of last sync |
+| `linksync_syncing` | boolean | Currently syncing flag |
+| `linksync_pending` | boolean | Has pending local changes |
+
+## Testing
+
+Browser extensions require manual testing in Firefox:
+
+1. Open `about:debugging` in Firefox
+2. Click "This Firefox" → "Load Temporary Add-on"
+3. Select `manifest.json` from the project folder
+4. Click the extension icon to open the popup
+5. Right-click the icon → "Options" for settings page
+
+See `tests/README.md` for the full manual testing checklist.
+
+## Development Notes
+
+- Manifest v2 for Firefox compatibility
+- Background page (not service worker) for Firefox support
+- All API calls use Bearer token auth (matching server's JWT implementation)
+- Content script runs on all pages to extract metadata
+- No external dependencies - pure browser APIs

 ```
 
+### How `build: .` Works
+
+In `docker-compose.yml`, the `web` service uses `build: .` instead of `image:`. This is a key distinction:
+
+| Key | Behavior |
+|-----|----------|
+| `image: postgres:15-alpine` | Pulls a pre-built image from Docker Hub |
+| `build: .` | Builds a custom image from a `Dockerfile` in the current directory (`.`) |
+
+**The build process works like this:**
+
+```
+docker-compose up --build
+        │
+        ▼
+  Reads docker-compose.yml
+        │
+        ▼
+  Finds build: . → looks for Dockerfile in current directory
+        │
+        ▼
+  Executes each instruction in the Dockerfile:
+    1. FROM python:3.12-slim       ← Base image
+    2. RUN apt-get install curl    ← Install system deps
+    3. COPY requirements.txt .     ← Copy dependency list
+    4. RUN pip install -r ...      ← Install Python packages
+    5. COPY . .                    ← Copy all project files
+    6. EXPOSE 5000                 ← Declare port
+    7. CMD ["uvicorn", ...]        ← Set startup command
+        │
+        ▼
+  Tags the built image as linksyncserver-web (auto-generated name)
+        │
+        ▼
+  Starts the container from the built image
+```
+
+**Why build instead of pull?**
+
+- You're running your own application code, not a third-party image
+- Every code change requires a rebuild to take effect
+- The `Dockerfile` defines exactly how your app is packaged
+
+**Rebuilding after code changes:**
+
+```bash
+# Rebuild and restart (picks up all code changes)
+docker-compose up -d --build
+
+# Rebuild without cache (forces fresh pip install)
+docker-compose build --no-cache && docker-compose up -d
+
+# Just restart without rebuilding (uses existing image)
+docker-compose restart
+```
+
+**The `--build` flag:** Forces Docker Compose to rebuild images before starting containers. Without it, Compose reuses any previously built image, meaning your code changes won't be reflected.

+## Deployment
+
+### Deploy Script
+
+The project includes `deploy.ps1` (Windows) and `deploy.sh` (Linux/macOS) to prepare a clean deployment package. These scripts copy only production files, exclude development artifacts (`tests/`, `__pycache__/`, `.git/`, etc.), and create a starter `.env` file.
+
+#### Usage
+
+```powershell
+# Windows
+.\deploy.ps1 C:\deploy\linksync
+```
+
+```bash
+# Linux/macOS
+chmod +x deploy.sh
+./deploy.sh /opt/deploy/linksync
+```

+
+#### Full Deployment Workflow
+
+```bash
+# 1. Clone the repository to a temporary location
+git clone <repo-url> /tmp/linksync-src
+cd /tmp/linksync-src
+
+# 2. Run the deploy script to prepare the package
+./deploy.sh /opt/linksync
+
+# 3. Configure production secrets
+cd /opt/linksync
+nano .env
+# Set these values:
+#   DATABASE_URL=postgresql://user:pass@db:5432/linksync
+#   SECRET_KEY=<generate with: openssl rand -base64 32>
+#   ADMIN_PASSWORD=<strong password>
+
+# 4. Build and start
+docker-compose up -d --build
+
+# 5. Verify
+curl http://localhost:5000/health
+
+# 6. Clean up the source clone
+rm -rf /tmp/linksync-src
+```
+
+#### Updating an Existing Deployment
+
+```bash
+# On the server, pull latest code and redeploy
+cd /tmp/linksync-src && git pull
+./deploy.sh /opt/linksync
+cd /opt/linksync
+docker-compose up -d --build
