The websocket-client strips the outer {type, data, ...} wrapper before
emitting to handlers, so handlers receive the inner series data object
directly (e.g. {key, name, missing_episodes}) — not {type, data: {...}}.
The series_updated handler was checking data.data which always failed,
causing every update to fall back to a full loadSeries() call instead of
calling updateSingleSeries() directly. This prevented the missing
episodes count from updating in real-time after a download completed.
Fix: check data.key directly and pass data (not data.data) to
updateSingleSeries().
- Implement sync_single_series_after_scan to persist scanned series to database
- Enhanced _broadcast_series_updated to include full NFO metadata (nfo_created_at, nfo_updated_at, tmdb_id, tvdb_id)
- Add immediate episode scanning in add_series endpoint when background loader isn't running
- Implement updateSingleSeries in frontend to handle series_updated WebSocket events
- Add SERIES_UPDATED event constant to WebSocket event definitions
- Update background loader to use sync_single_series_after_scan method
- Simplified background loader initialization in FastAPI app
- Add comprehensive tests for series update WebSocket payload and episode counting logic
- Import reorganization: move get_background_loader_service to dependencies module
- Add SERIES_LOADING_UPDATE WebSocket event
- Update series cards to display loading indicators
- Add real-time status updates via WebSocket
- Include progress tracking (episodes, NFO, logo, images)
- Add CSS styling for loading states
- Implement updateSeriesLoadingStatus function
- Extended AnimeSummary model with NFO fields (has_nfo, nfo_created_at, nfo_updated_at, tmdb_id, tvdb_id)
- Updated list_anime endpoint to fetch and return NFO data from database
- Added NFO status badges to series cards (green=exists, gray=missing)
- Created nfo-manager.js module with createNFO, refreshNFO, viewNFO operations
- Added NFO action buttons to series cards (Create/View/Refresh)
- Integrated WebSocket handlers for real-time NFO events (creating, completed, failed)
- Added CSS styles for NFO badges and action buttons
- All 34 NFO API tests passing, all 32 anime endpoint tests passing
- Documented in docs/task6_status.md (90% complete, NFO status page deferred)
