- Only trigger background refresh if cache is incomplete (less than max records)
- Only update cache if background fetch returns records (don't overwrite on failure)
- Prevents test failures when background fetch fails to connect to Sonarr/Radarr
- Fixes integration test 'includes imported and failed records, excludes grabbed'
- Fix history pagination: use retriever's built-in maxPages parameter instead of broken date-based cursor
- Fix status panel: correct API endpoint from /api/dashboard/status to /api/status
- Background fetch now properly fetches up to 1000 records (10 pages * 100 records)
- Status panel will now display details instead of 'Loading Status...'
- Stage 1: Fetch 100 records immediately for fast display
- Stage 2+: Background fetch up to 1000 records in batches of 100
- Date-based cursor pagination to avoid race conditions
- Deduplication by record ID to prevent duplicates
- SSE push to clients when history cache is updated
- Shared background fetch state for concurrent user requests
- Remove instanceConfig parameter from all retriever methods (getTags, getQueue, getHistory)
- Retriever instances now use this.url, this.apiKey, this.id instead of passed parameter
- Convert ArrRetrieverRegistry from class with convenience functions to pure singleton object
- Export singleton instance directly instead of class + convenience functions
- Update poller.js and historyFetcher.js to call methods on singleton directly
- All 261 tests pass with zero behavior changes
- Create ArrRetriever abstract base class defining pluggable interface
- Implement PollingSonarrRetriever and PollingRadarrRetriever with HTTP polling
- Add ArrRetrieverRegistry for managing retriever instances
- Refactor poller.js to use retriever registry instead of direct Axios calls
- Update historyFetcher.js to use retriever registry
- Preserve all cache keys, TTLs, timing logs, SSE broadcasts, error handling
- Enable future webhook listeners without touching poller logic
- Add includeEpisode:true to Sonarr queue and history API requests
in both the poller and historyFetcher
- Add extractEpisode() / gatherEpisodes() helpers in dashboard.js
and history.js to build a sorted, deduplicated episodes array
covering all records matching a download title (handles multi-
episode packs and series packs)
- Replace episodeInfo: sonarrMatch with episodes: gatherEpisodes()
across all 8 assignment sites in dashboard.js
- Add episodes field to /api/history/recent response items
- Frontend: formatEpisodeInfo() renders S01E05 for single episodes
or 'Multiple episodes' with hover tooltip listing all for packs
- CSS: .episode-info and .multi-episode tooltip styles
- ARCHITECTURE.md: update polling table and download/history schemas
