+### Core Services WebSocket Integration (October 2025)
+
+Completed comprehensive integration of WebSocket broadcasting with all core services (DownloadService, AnimeService, ProgressService) to provide real-time updates to connected clients.
+
+#### DownloadService WebSocket Integration
+
+**File**: `src/server/services/download_service.py`
+
+The download service broadcasts real-time updates for all queue and download operations:
+
+**Download Progress Broadcasting**:
+
+-   `download_progress` - Real-time progress updates during download
+    -   Includes: download_id, serie_name, season, episode, progress data (percent, speed, ETA)
+    -   Sent via ProgressService which broadcasts to `download_progress` room
+    -   Progress callback created for each download item with metadata tracking
+
+**Download Completion/Failure Broadcasting**:
+
+-   `download_complete` - Successful download completion
+    -   Includes: download_id, serie_name, season, episode, downloaded_mb
+    -   Broadcast to `downloads` room
+-   `download_failed` - Download failure notification
+    -   Includes: download_id, serie_name, season, episode, error, retry_count
+    -   Broadcast to `downloads` room
+
+**Queue Operations Broadcasting**:
+All queue operations broadcast `queue_status` messages with current queue state:
+
+-   `items_added` - Items added to queue
+    -   Data: added_ids, queue_status (complete queue state)
+-   `items_removed` - Items removed/cancelled
+    -   Data: removed_ids, queue_status
+-   `queue_reordered` - Queue order changed
+    -   Data: item_id, new_position, queue_status
+-   `items_retried` - Failed items retried
+    -   Data: retried_ids, queue_status
+-   `completed_cleared` - Completed items cleared
+    -   Data: cleared_count, queue_status
+
+**Queue Control Broadcasting**:
+
+-   `queue_started` - Queue processor started
+    -   Data: is_running=True, queue_status
+-   `queue_stopped` - Queue processor stopped
+    -   Data: is_running=False, queue_status
+-   `queue_paused` - Queue processing paused
+    -   Data: is_paused=True, queue_status
+-   `queue_resumed` - Queue processing resumed
+    -   Data: is_paused=False, queue_status
+
+**Broadcast Callback Setup**:
+The download service broadcast callback is registered during dependency injection in `src/server/utils/dependencies.py`:
+
+-   Maps update types to WebSocket service methods
+-   Routes download_progress, download_complete, download_failed to appropriate rooms
+-   All queue operations broadcast complete queue status for client synchronization
+
+#### AnimeService WebSocket Integration
+
+**File**: `src/server/services/anime_service.py`
+
+The anime service integrates with ProgressService for library scan operations:
+
+**Scan Progress Broadcasting**:
+
+-   Scan operations use ProgressService for progress tracking
+-   Progress updates broadcast to `scan_progress` room
+-   Lifecycle events:
+    -   `started` - Scan initialization
+    -   `in_progress` - Ongoing scan with current/total file counts
+    -   `completed` - Successful scan completion
+    -   `failed` - Scan failure with error message
+
+**Scan Implementation**:
+
+-   `rescan()` method wraps SeriesApp.ReScan with progress tracking
+-   Progress callback executed in threadpool updates ProgressService
+-   ProgressService automatically broadcasts to WebSocket clients
+-   Cache invalidation on successful scan completion
+
+#### ProgressService WebSocket Integration
+
+**File**: `src/server/services/progress_service.py`
+
+Central service for tracking and broadcasting all progress operations:
+
+**Progress Types**:
+
+-   `DOWNLOAD` - File download progress
+-   `SCAN` - Library scan progress
+-   `QUEUE` - Queue operation progress
+-   `SYSTEM` - System-level operations
+-   `ERROR` - Error notifications
+
+**Progress Lifecycle**:
+
+1. `start_progress()` - Initialize progress operation
+    - Broadcasts to room: `{progress_type}_progress`
+2. `update_progress()` - Update progress values
+    - Calculates percentage automatically
+    - Broadcasts only on significant changes (>1% or forced)
+3. `complete_progress()` - Mark operation complete
+    - Sets progress to 100%
+    - Moves to history
+    - Broadcasts completion
+4. `fail_progress()` - Mark operation failed
+    - Captures error message
+    - Moves to history
+    - Broadcasts failure
+
+**Broadcast Callback**:
+
+-   Callback registered during application startup in `src/server/fastapi_app.py`
+-   Links ProgressService to WebSocketService.manager.broadcast_to_room
+-   All progress updates automatically broadcast to appropriate rooms
+
+#### WebSocket Room Structure
+
+Clients subscribe to specific rooms to receive targeted updates:
+
+**Room Types**:
+
+-   `downloads` - All download-related events (complete, failed, queue status)
+-   `download_progress` - Real-time download progress updates
+-   `scan_progress` - Library scan progress updates
+-   `queue_progress` - Queue operation progress (future use)
+-   `system_progress` - System-level progress (future use)
+
+**Room Subscription**:
+Clients join rooms by sending WebSocket messages:
+
+```json
+{
+    "action": "join",
+    "room": "download_progress"
+}
+```
+
+#### Message Format
+
+All WebSocket messages follow a consistent structure:
+
+```json
+{
+  "type": "download_progress" | "download_complete" | "queue_status" | etc.,
+  "timestamp": "2025-10-17T12:34:56.789Z",
+  "data": {
+    // Message-specific data
+  }
+}
+```
+
+**Example: Download Progress**
+
+```json
+{
+    "type": "download_progress",
+    "timestamp": "2025-10-17T12:34:56.789Z",
+    "data": {
+        "download_id": "abc123",
+        "serie_name": "Attack on Titan",
+        "season": 1,
+        "episode": 5,
+        "progress": {
+            "percent": 45.2,
+            "downloaded_mb": 226.0,
+            "total_mb": 500.0,
+            "speed_mbps": 2.5,
+            "eta_seconds": 120
+        }
+    }
+}
+```
+
+**Example: Queue Status**
+
+```json
+{
+  "type": "queue_status",
+  "timestamp": "2025-10-17T12:34:56.789Z",
+  "data": {
+    "action": "items_added",
+    "added_ids": ["item1", "item2"],
+    "queue_status": {
+      "is_running": true,
+      "is_paused": false,
+      "active_downloads": [...],
+      "pending_queue": [...],
+      "completed_downloads": [...],
+      "failed_downloads": [...]
+    }
+  }
+}
+```
+
+#### Integration Testing
+
+**File**: `tests/integration/test_websocket_integration.py`
+
+Comprehensive integration tests verify WebSocket broadcasting:
+
+**Test Coverage**:
+
+-   Download progress broadcasts during active downloads
+-   Queue operation broadcasts (add, remove, reorder, clear, retry)
+-   Queue control broadcasts (start, stop, pause, resume)
+-   Scan progress broadcasts (start, update, complete, fail)
+-   Progress lifecycle broadcasts for all operation types
+-   End-to-end flow with multiple services broadcasting
+
+**Test Strategy**:
+
+-   Mock broadcast callbacks to capture emitted messages
+-   Verify message types, data structure, and content
+-   Test both successful and failure scenarios
+-   Verify proper room routing for different message types
+
+#### Architecture Benefits
+
+**Decoupling**:
+
+-   Services use generic broadcast callbacks without WebSocket dependencies
+-   ProgressService provides abstraction layer for progress tracking
+-   Easy to swap WebSocket implementation or add additional broadcast targets
+
+**Consistency**:
+
+-   All services follow same broadcast patterns
+-   Standardized message formats across application
+-   Unified progress tracking via ProgressService
+
+**Real-time UX**:
+
+-   Instant feedback on all long-running operations
+-   Live queue status updates
+-   Progress bars update smoothly without polling
+-   Error notifications delivered immediately
+
+**Scalability**:
+
+-   Room-based messaging enables targeted updates
+-   Multiple concurrent operations supported
+-   Easy to add new progress types and message formats
+
+#### Production Considerations
+
+**Single-Process Deployment** (Current):
+
+-   In-memory connection registry in WebSocketService
+-   Works perfectly for single-worker deployments
+-   No additional infrastructure required
+
+**Multi-Process/Multi-Host Deployment** (Future):
+
+-   Move connection registry to Redis or similar shared store
+-   Implement pub/sub for cross-process message broadcasting
+-   Add connection persistence for recovery after restarts
+-   Consider using sticky sessions or connection migration
+
+**Performance**:
+
+-   Progress updates throttled to >1% changes to reduce message volume
+-   Broadcast operations are fire-and-forget (non-blocking)
+-   Failed connections automatically cleaned up
+-   Message serialization cached where possible
+
+**Monitoring**:
+
+-   Structured logging for all broadcast operations
+-   WebSocket status available at `/ws/status` endpoint
+-   Connection count and room membership tracking
+-   Error tracking for failed broadcasts
