If yes, reuse it. -- How is NFO currently generated? Wrap existing logic, don't duplicate. -- Where are images downloaded? Use existing service. -- What WebSocket message format is already in use? Follow the pattern. -- Are there any existing background task patterns? Align with them. - -**Deliverables:** - -- Architecture document with diagrams -- List of existing methods to reuse -- List of new methods to create -- Refactoring tasks (if any) -- Database migration plan -- API specification - -**Estimated Time:** 2-3 hours - -**Note:** Do not proceed to implementation until this planning phase is complete and reviewed.

-#### Success Criteria - -- [ ] Users can add series and see them immediately in UI -- [ ] Loading status is clearly visible with progress indicators -- [ ] Real-time updates via WebSocket work correctly -- [ ] Application startup checks and loads missing data automatically -- [ ] Background loading doesn't impact UI responsiveness -- [ ] Errors are handled gracefully without stopping other loads -- [ ] All unit and integration tests pass -- [ ] Documentation is complete and accurate -- [ ] Code follows project standards and best practices - -#### Files to Create/Modify - -**Create:** - -- `src/server/services/background_loader_service.py` -- `migrations/add_loading_status.py` -- `tests/unit/test_background_loader_service.py` -- `tests/integration/test_async_series_loading.py` -

-#### Notes - -- Use `asyncio.Queue` for task management -- Implement exponential backoff for retry logic -- Consider rate limiting to avoid overwhelming TMDB API -- Log all background operations for debugging -- Ensure thread-safety for shared data structures -- Handle network errors and timeouts gracefully -- Consider implementing priority queue for user-initiated loads vs startup loads -- Add monitoring/metrics for background task performance - -#### Dependencies - -- Requires WebSocket service to be fully functional -- Requires series service with episode/NFO/image loading capabilities -- May need database schema migration - -#### Estimated Effort -
