When >50% of files are flagged as orphans (likely a DB path mismatch),
findings are marked as warnings with mass_orphan flag. Fixing these
requires typing "witness me" to confirm — prevents nuking an entire
library from a false-positive orphan scan.
_sanitize_context_values passed empty strings through _sanitize_filename
which converts '' to '_' (empty-name fallback). Template $album ($year)
became Album (_) instead of Album () which the cleanup regex couldn't
match. Now preserves empty strings so the existing () cleanup works.
- Add _fix_path_mismatch handler so fixing Library Reorganize dry-run
findings actually moves files (was returning 400 with no handler)
- Add path_mismatch to fixable_types and _execute_fix handler map
- Add recent_releases and wishlist_tracks as year sources in
_load_album_years to cover more playlist-synced tracks missing years
- Add sys and json imports needed by new code
- Add single_album_redundant to fixable_types in bulk_fix_findings so
Fix All actually includes these findings (Fix Selected worked, Fix All
silently returned 0)
- Expand version keyword regex from 9 to 25 terms (remastered, deluxe,
unplugged, etc.) to reduce false positives in Single/Album Dedup
- Add word boundary anchors to prevent substring matches (e.g. "live"
inside "Alive", "edit" inside "Meditate")
- Cast similarity thresholds to float for config type safety
The SQL HAVING clause filtered on local track count instead of expected
track count, excluding albums with fewer than 3 local tracks from the
scan entirely. Now fetches all Spotify-matched albums and filters by
expected track count in the loop.
- Frontend was concatenating Track and Artist inputs into a single
query string, causing Spotify to return mixed results matching
either word in any field. Now sends track and artist as separate
params; backend builds field-filtered query (track:X artist:Y).
- Result limit was silently capped at 10 in spotify_client.search_tracks
via min(limit, 10). Raised to respect requested limit up to
Spotify's API max of 50.
- iTunes fallback endpoint updated with same field-specific params.
- Legacy ?query= param still supported for backward compatibility.
Fixes#194
EPs are no longer classified as singles — removing EP tracks would
break the release and conflict with album completeness checks.
Only actual singles (album_type='single' or unknown type with <=2
tracks) are flagged as redundant when the same song exists on an album.
Tracks on different albums (e.g., same song on a studio album and a
compilation) are no longer flagged as duplicates by default, keeping
albums complete. Setting is enabled by default and configurable via
the job settings UI.
Playlist-synced tracks often have no year in file tags or the DB albums
table. Now checks discovery_pool release_date as a second DB source,
then batch-lookups remaining missing years from the user's active
metadata source (Spotify/iTunes/Deezer) capped at 50 API calls.
Multiple code paths built wishlist album data as a bare string instead
of a dict with images/album_type/total_tracks, causing wishlist entries
to lose album name and artwork. Fixed in: Beatport fallback conversion,
sync normalization, _ensure_spotify_track_format, and wishlist service
track reconstruction. Now uses track name as album fallback and always
includes required album dict keys.
New dropdown in Soulseek settings lets users filter out slow peers at
search time (Any/1/2/3/4/5/10 Mbps). Passes minimumPeerUploadSpeed
to slskd API in bytes/sec.
Also fixes quality scoring tiers which were using wrong units — old
thresholds (5000, 1000, 500) treated bytes/sec values as kbps,
making speed scoring effectively meaningless. Now uses correct
bytes/sec thresholds based on real peer data.
Deep scan passed skip_existing_tracks=True which skipped calling
insert_or_update_media_track entirely for known tracks, so stale
file paths were never refreshed from the media server. Now always
calls insert_or_update (which safely uses UPDATE for existing tracks,
preserving enrichment data) so file paths stay in sync.
Normalization was stripping parenthetical content before comparison,
so 'title' and 'title (xxx remix)' both became 'title' and always
matched at 1.0 regardless of the user's threshold setting.
_get_source() hardcoded 'itunes' as fallback, so seasonal content was
stored with source='itunes' but API endpoints queried source='deezer' —
resulting in empty discover page seasons. Now reads the configured
fallback source from metadata_service.
Dead file Fix button now adds the track to wishlist for re-download
instead of just removing the DB entry. Builds full wishlist-compatible
track data from DB (artist, album, artwork, IDs) so the download
pipeline can process it like any other wishlist item.
- Add null guard for soulseek_client in test-connection endpoint (#190)
- Fix single_album_dedup query: use al.record_type and al.track_count
(al.album_type and al.total_tracks don't exist on main albums table)
- Fix library reorganize missing year: pre-load album years from DB as
fallback when file tags lack the date field (common with playlist syncs)
- Fix enrichment progress never updating: remove `continue` that skipped
progress_callback for successful tracks in enrich_chart_tracks
- Split chart/extract into two-step flow: extract raw tracks, then enrich
via polling endpoint with live progress overlay updates
- Move Beatport enrichment cache to persistent metadata cache system
- Fix metadata cache detail modal for Beatport (URL entity_ids with slashes)
- Add per-source Clear dropdown (Spotify/iTunes/Deezer/Beatport) to cache browser
- Remove debug logging from enrichment progress tracking
When the maintenance worker flags an incomplete album, users can now
click "Auto-Fill" to automatically locate missing tracks in the library,
move/copy them into the album folder, and apply full metadata enhancement
(MusicBrainz, Deezer, cover art, etc.). Singles are moved; tracks from
multi-track albums are copied. Quality gate prevents filling FLAC albums
with lossy files. Tracks not found in library are added to wishlist with
album context for auto-download.
Both clients have their own Track class separate from iTunes. The
album preference commit added album_type/total_tracks to from_*_track()
constructors but not to the class definitions, crashing all Deezer and
Spotify discovery searches.
Scans library for tracks on singles/EPs that also exist on a full album,
letting users clean up fragmented libraries. Includes version-tag safety
(live, acoustic, remix etc. won't cross-match) and verifies the album
version still exists before removing a single.
Add album_type and total_tracks fields to Track dataclass, populate from
Spotify/iTunes/Deezer API responses, and apply a small tiebreaker bonus
(+0.02 for albums, +0.01 for EPs) in all matching loops so album versions
win when confidence scores are otherwise equal.
Deezer search results (cached without release_date, track_position, isrc)
were being served by get_track_details as cache hits, preventing the actual
/track/{id} API call that returns complete data. This caused $year template
variable to remain empty even with the discovery worker fix in place.
trigger_library_scan and is_library_scanning were no-ops assuming
Navidrome auto-detects new files. Navidrome supports startScan and
getScanStatus via the Subsonic API, so use them like Plex and Jellyfin.
- DB path update uses suffix matching when exact match fails, so server
paths (/mnt/musicBackup/...) are found and updated after local moves
- Escape LIKE wildcards in artist/album names to prevent false matches
- Move album-level sidecars (cover.jpg, folder.jpg, etc.) alongside audio
- Post-pass sweep moves all remaining sidecars from emptied directories
- Multi-disc albums place album art in album root, not disc subfolders
Use config_manager for transfer path (same source as playback) instead of
separate DB read that silently falls back to ./Transfer under contention.
Abort scan if transfer folder doesn't exist to prevent mass false findings.
- personalized_playlists._get_active_source() now returns 'deezer' when
configured instead of always falling back to 'itunes'
- Add deezer_track_id to _build_track_dict() for discovery pool tracks
- Include album_deezer_id and artist_deezer_id in get_discovery_recent_albums()
response — fixes "No deezer album ID available" error when clicking cards
- Skip Spotify library section entirely when Spotify is not authenticated
Per-job and per-status filtering — respects active toolbar filters so
users can clear e.g. only track number findings or only dismissed items.
Confirmation uses the app's styled modal instead of browser confirm().
Previously only 502/503/504 triggered instance rotation. A 500 from one
instance (e.g. triton.squid.wtf choking on a specific query) would stop
the search entirely instead of trying the next instance.
Users can now choose between iTunes/Apple Music and Deezer as their free
metadata source in Settings. Spotify always takes priority when authenticated;
the fallback handles all lookups when it's not.
Core changes:
- DeezerClient: full metadata interface (search, albums, artists, tracks)
matching iTunesClient's API surface with identical dataclass return types
- SpotifyClient: configurable _fallback property switches between iTunes/Deezer
based on live config reads (no restart needed)
- MetadataService, web_server, watchlist_scanner, api/search, repair_worker,
seasonal_discovery, personalized_playlists: all direct iTunesClient imports
replaced with fallback-aware helpers
Database:
- deezer_artist_id on watchlist_artists and similar_artists tables
- deezer_track_id/album_id/artist_id on discovery_pool and discovery_cache
- Full CRUD for Deezer IDs: add, read, update, backfill, metadata enrichment
- Watchlist duplicate detection by artist name prevents re-adding across sources
- SimilarArtist dataclass and all query/insert methods handle Deezer columns
Bug fixes found during review:
- Similar artist backfill was writing Deezer IDs into iTunes columns
- Discover hero was storing resolved Deezer IDs in wrong column
- Status cache not invalidating on settings save (source name lag)
- Watchlist add allowing duplicates when switching metadata sources
Add minimum 60% title similarity gate to match_recording() — prevents
artist bonus + MB score from pushing unrelated titles past the confidence
threshold (e.g. "Sweet Surrender" matching "Answers" by same artist).
New MBID Mismatch Detector repair job reads embedded MusicBrainz recording
IDs from audio files, verifies them against the MusicBrainz API, and flags
tracks where the MBID points to a different song. Fix action strips the bad
MBID tag so media servers like Navidrome fall back to correct file tags.
New download mode alongside Soulseek, YouTube, Tidal, and Qobuz. Uses
community-run REST API instances (no auth required) that serve Tidal CDN
FLAC streams. Features quality fallback chain (hires→lossless→high→low),
automatic instance rotation on failure, and full hybrid mode support.
Also fixes 6 missing streaming source checks for HiFi and Qobuz in the
frontend that were blocking playback with "format not supported" errors.
Scrapes Spotify's embed endpoint to extract track data from any public
playlist or album URL. Full discovery flow with Deezer parity: parse →
card → discovery modal → live progress → sync → download missing.
- New scraper: core/spotify_public_scraper.py (embed endpoint parsing)
- 12 API endpoints mirroring Deezer's discovery/sync/download flow
- WebSocket live discovery updates via spotify_public_discovery_states
- Green-branded tab, cards, and input styling (#1DB954)
- Album vs playlist detection with distinct card icons (💿/🎵)
- Download persistence: card click reopens download modal after close
- Card phase reset on cancel/completion (closeDownloadMissingModal)
- Backend download linking for spotify_public_ and deezer_ prefixes
- Completion handlers (V2 + no-missing-tracks) for both platforms
- Source URLs stored on mirrored playlists for future auto-refresh
Southern hemisphere users now see correct seasons (e.g. March = Autumn,
December = Summer). Holidays (Halloween, Christmas, Valentine's) stay
calendar-fixed regardless of hemisphere.
- Hemisphere dropdown in Discovery Pool Settings
- GET/POST /api/discovery/hemisphere endpoints
- Season detection offsets months by 6 for southern hemisphere
- Stored in metadata table, defaults to northern
Repair jobs were making Spotify API calls without checking the global
rate limit ban, causing them to churn through every item getting rejected
one by one during a ban. Now all Spotify calls in repair jobs check
context.is_spotify_rate_limited() first and skip/fallback gracefully.
- Add is_spotify_rate_limited() helper to JobContext (base.py)
- Guard calls in track_number_repair, album_completeness,
missing_cover_art, and metadata_gap_filler
- Jobs fall through to iTunes/MusicBrainz fallbacks when rate-limited
- All 9 repair jobs now emit report_progress() for real-time card updates
(phase, log lines, per-item activity) via WebSocket repair:progress events
- Enrich finding details with album/artist thumb URLs across all repair jobs
(dead_file, duplicate, metadata_gap, album_completeness, missing_cover_art,
acoustid_scanner, track_number_repair, fake_lossless, orphan_file)
- Track number repair: return match_score from fuzzy matching, add suffix-based
DB lookup for album/artist art (handles cross-environment path mismatches)
- Fix Plex/Jellyfin relative thumb URLs in findings endpoint via fix_artist_image_url
- Labeled media cards in finding detail panels (album title + artist name under images)
- Dashboard tooltip shows current job name + per-job progress instead of stale stats
- Add whisoul.png to modal header with subtitle text and gradient background
- Responsive: smaller logo on mobile, hide subtitle
- Share _resolve_file_path in repair_worker for cross-environment path compat
- Use path resolution in orphan and duplicate file deletion
- Guard directory cleanup against removing the transfer folder itself
- Restore correct button label text on fix error recovery
- Add findings dashboard with summary stats and per-job clickable filter chips
- Redesign findings cards with expandable detail panels and per-type renderers
- Redesign history tab with status dots, stat pills, and full timestamps
- Fix dead file cleaner false positives by using suffix-based path resolution
- Fix orphan file detector false positives by matching via path suffixes
- Add help text modal for each repair job card
- Enlarge maintenance modal (1100px wide, 90vh tall)
Allow multiple users to share a single SoulSync instance with isolated personal data. Each profile gets its own watchlist, wishlist, discovery pool, similar artists, and bubble snapshots — while sharing the same music library, database, and service credentials.
- Netflix-style profile picker on startup when multiple profiles exist
- Optional PIN protection per profile; admin PIN required when >1 profiles
- Admin-only profile management (create, edit, rename, delete)
- Profile avatar images via URL with colored-initial fallback
- Zero-downtime SQLite migration — all existing data maps to auto-created
admin profile
- Single-user installs see no changes — profile system is invisible until
a second profile is created
- WebSocket count emitters scoped to profile rooms (watchlist/wishlist)
- Background scanners (watchlist, wishlist, discovery) iterate all profiles
Incremental database updates now detect when artists or albums have been removed from your media server (Plex, Jellyfin, or Navidrome) and automatically clean them up from SoulSync's database. Previously, deleted content would persist as ghost entries until you ran a full refresh. Removal counts are reported in the scan results. Includes safety checks to prevent accidental mass deletion if the server is unreachable or returns incomplete data.
Adds Tidal as a third download source alongside Soulseek and YouTube. Uses the tidalapi library with device-flow authentication to search and download tracks in configurable quality (Low/High/Lossless/HiRes) with automatic fallback. Integrates into the download orchestrator for all modes (Tidal Only, Hybrid with fallback chain), the transfer monitor, post-processing pipeline, and file finder. Frontend includes download settings with quality selector, device auth flow, and dynamic sidebar/dashboard labels that reflect the active download source. No breaking changes for existing users.
Filled all missing Hydrabase fallthrough gates across 6 endpoints (artist album tracks, iTunes album, discover album, Spotify track, both similar artists), added track_number/disc_number to Track dataclass, fixed get_album_tracks to send soul_id instead of text query, mapped soul_id field from Hydrabase responses across all search methods, updated 7 frontend call sites to pass album name/artist params, and fixed M3U export defaulting to enabled when users never turned it on.
Fix short artist names (e.g. "ano") getting buried by wildcard matches. Re-ranks Spotify and iTunes results so exact name matches appear first, without changing what's returned.
SoulSync was importing from all Navidrome libraries regardless of user access restrictions. Added a "Music Library" dropdown in Navidrome settings that lets users scope imports to a specific music folder. Uses the Subsonic musicFolderId parameter on artist, album, and search API calls. Selecting "All Libraries" reverts to the previous behavior.
AcoustID sometimes returns featuring info in square brackets like [W/ Barnes Blvd.] instead of parentheses. The normalizer only stripped parenthetical featuring tags, so these tracks failed verification and got quarantined despite being correct. Now strips [W/ ...], [with ...], [feat. ...], and [ft. ...] bracket patterns too.
Store album artists in the Spotify track data structure (handles both dict and object album forms) so downstream processing has access to album-level artist metadata. Also update missing-track processing to fall back to source_info['watchlist_artist_name'] when artist_name is absent, ensuring artist context is preserved for legacy/watchlist-sourced entries.
Raise the default Jellyfin API timeout for bulk operations from 30s to 120s to better handle slow servers and large database syncs. Updated core/jellyfin_client.py to set bulk_timeout to 120, webui/index.html to show 120s in the settings input, and webui/static/script.js to use 120 as the fallback when loading settings. Aligns UI and client behavior to reduce timeout errors during heavy syncs.
Add a configurable API timeout for Jellyfin bulk requests and improve fetch retry behavior. UI: adds an "API Timeout (seconds)" field (15–300s, default 30) in webui/index.html and persists it via webui/static/script.js (load/save). Client: jellyfin_client.py now reads api_timeout from config_manager, uses it as the bulk timeout and computes a sensible non-bulk timeout (max(5, bulk_timeout//6)). Fetch loops for tracks and albums were hardened: reducing batch size now resets consecutive failure counters, log messages were clarified, and the stopping/retry thresholds were adjusted to avoid premature aborts at minimum batch sizes.
Introduce a generic score_track_match(...) in core/matching_engine.py and make calculate_match_confidence(...) delegate to it. The new scorer is source-agnostic, consolidates artist/title/duration logic (core-title fast path, cleaned similarity, weighted 60/30/10 scoring) and improves artist matching.
In web_server.py add cache-validation (_validate_discovery_cache_artist) and a reusable _discovery_score_candidates(...) helper that calls the new scorer. Propagate per-match confidence through discovery flows (Tidal, YouTube, ListenBrainz, Beatport), increase Spotify/iTunes search limits, add an extended high-limit search strategy, tighten per-source thresholds, and save match confidence to the discovery cache. Overall this centralizes and standardizes matching logic and improves accuracy/validation for cached discovery results.
Expand track title normalization and refine album grouping logic.
- core/acoustid_verification.py: Broadened the parenthetical-suffix regex to strip year-based remasters and additional variants (e.g. "2025 Remaster", "single edit", "album edit") while still removing common extras like (Live), (Deluxe), (Radio Edit), and featuring tags.
- web_server.py: Restrict the smart album grouping to only run for singles/auto-detected albums; explicit album downloads now preserve the original Spotify album name to avoid mangling names (e.g. reworked/remastered vs deluxe). Added explicit logging for both smart grouping and skipped grouping paths. The verification post-processing worker now checks an is_album_download flag in context and skips re-grouping when true, with fallback logging on errors.
These changes prevent unintended renaming of explicit album downloads and improve normalization of common title suffixes.
- matching_engine.py: Add 'single edit' and 'album edit' tokens and clarify radio edit comment so edit/cut variants are recognized as different cuts rather than being silently normalized away.
- database/music_database.py: Fix SQL param ordering by appending server_source to params; add a pre-step to strip "(with ...)" / "[with ...]" only when used inside brackets (so titles like "Stay With Me" are preserved); stop removing edit/version tokens in the generic cleanup and document that radio/single/album edits are treated as distinct by the similarity scorer to avoid incorrect matches.
- web_server.py: Increase DB match confidence threshold from 0.70 to 0.80 and update the runtime check accordingly.
These changes prevent edit/cut variants from being conflated with original recordings, improve title normalization for "with" featuring syntax in brackets, and fix a params ordering bug and a too-low match threshold.
Use UUID nonces to correlate requests/responses and robustly handle interleaved stats/heartbeat messages from the Hydrabase server. Adds _extract_stats and _extract_results helpers, records last_peer_count and timestamp, and loops on recv() with timeouts to drain non-result messages until the matching response (or a results message without a nonce) arrives. Mirrors the same nonce/send-and-drain logic in HydrabaseWorker, adds necessary imports (time, uuid), and improves logging and timeout handling to avoid returning stale or misattributed data.
Improve Hydrabase response handling and add discography/album track helpers. core/hydrabase_client.py: extract peer counts from stats.connectedPeers, handle new "response" key and stats-only or unexpected response shapes (return empty instead of wrapping), and add search_discography() and get_album_tracks() to map Hydrabase results into Album/Track objects. web_server.py: avoid redundant Hydrabase round-trips by passing precomputed hydrabase_counts into the background comparison worker; prefer Hydrabase for artist discography and album track import when active (with Spotify fallback); and route album-context searches to Hydrabase when configured. These changes reduce duplicate network calls and improve robustness against varied Hydrabase payloads.
Add Hydrabase support as an optional/dev metadata source and comparison tool.
- Add core/hydrabase_client.py: synchronous Hydrabase WebSocket client that normalizes results to Track/Artist/Album types and exposes raw access.
- Update config/settings.py: add hydrabase settings (url, api_key, auto_connect) and getter.
- Update web_server.py: integrate HydrabaseClient, initialize client alongside the existing HydrabaseWorker, add auto-reconnect using saved config, persist credentials on connect/disconnect, add endpoints for status and stored comparisons, background comparison runner (Hydrabase vs Spotify vs iTunes), and adapt multiple search endpoints to optionally use Hydrabase as the primary metadata source with fallbacks.
- Update web UI (webui/index.html, webui/static/script.js, webui/static/style.css): add network stats and source comparison UI, pre-fill saved credentials, show peer count, load/display comparisons, update disconnect behavior to disable dev mode, and add Hydrabase badge styling.
Behavioral notes: when dev mode + Hydrabase are active, searches can be served from Hydrabase and comparisons to Spotify/iTunes are run in background; when Hydrabase fails the code falls back to Spotify/iTunes. Saved Hydrabase credentials are persisted for auto-reconnect; disconnect disables dev mode and auto_connect.
Files touched: config/settings.py, core/hydrabase_client.py, web_server.py, webui/index.html, webui/static/script.js, webui/static/style.css.
Increase Spotify client rate limit and reduce API contention during watchlist scans. Changes:
- core/spotify_client.py: Bumped MIN_API_INTERVAL from 0.2s to 0.35s (~171 calls/min) to stay safely under Spotify's ~180/min limit.
- web_server.py: In start_watchlist_scan and automatic scan flow, pause spotify_enrichment_worker and itunes_enrichment_worker before scanning (tracking with _enrichment_was_running/_itunes_enrichment_was_running) and resume them in finally blocks; added console prints for pause/resume. This prevents enrichment workers from contending for API quota during long scans.
- webui/static/script.js: Improved enrichment status tooltip logic to prioritize explicit currentType and then fall back to completion-based inference with explicit branches for artists, albums, and tracks for clearer progress text.
These changes aim to avoid API rate violations and make scan progress display more predictable.
When clearing the wishlist or changing the discovery lookback period, reset watchlist_artists.last_scan_timestamp to NULL so subsequent scans can re-discover older releases that were previously filtered by an earlier scan timestamp. clear_wishlist now deletes wishlist_tracks, updates last_scan_timestamp for all watchlist artists, and logs the number of tracks cleared and artists reset. set_discovery_lookback_period also resets last_scan_timestamp and reports how many artists were reset. Minor whitespace cleanups in watchlist_scanner and web_server included.
Add a release_date field to the Track dataclass for both iTunes and Spotify clients (iTunes: parsed from releaseDate, Spotify: from album.release_date). Propagate release_date into enhanced search results in web_server and into the client-side script so album objects include release_date when available. Also broaden playlistId matching in the missing-tracks process to include 'enhanced_search_track_'. Removed SQLite SHM/WAL files from the repo (cleanup of DB temporary files). These changes enable showing and using track release dates across the app.
Add duplicate-artist detection/merge and handle ratingKey (ID) migrations for artists and albums. Introduces MusicDatabase.merge_duplicate_artists that picks a canonical artist (most enrichment data), merges enrichment fields, migrates albums/tracks, and removes duplicates; DatabaseUpdateWorker now runs this merge during updates (even when no new content) and after orphan cleanup. insert_or_update_artist/album now detect same-name/title + server_source collisions (ratingKey changes), inserting a new record while preserving enrichment and migrating references, with safe deletion of old rows. Also deduplicate artist listing queries so results show a single canonical row per name+server_source while aggregating album/track counts across duplicates. Logging improved to report merge/migration outcomes.
Introduce deferred album repair scanning and robust tracklist resolution plus UI/presentation tweaks.
- core/repair_worker.py: Add lazy MusicBrainz and AudioDB client accessors, per-batch folder queues, and register_folder/process_batch to defer folder scans until a batch completes. Implement cascading tracklist resolution (_resolve_album_tracklist) using Spotify/iTunes IDs, Spotify track→album lookup, album search, MusicBrainz release lookup, and AudioDB→MusicBrainz fallback. Add helpers to read Spotify track IDs, MusicBrainz album IDs, album/artist tags from files, MB/AudioDB fetchers, placeholder-ID filtering, and rename associated .lrc files when renaming audio files. Cache/locking and background-threaded scanning included. Improves resilience to missing/placeholder IDs and avoids circular imports.
- web_server.py: Register album folders for repair in post-processing and trigger repair_worker.process_batch when batches complete (multiple completion paths) so scans run after downloads finish.
- webui/static/script.js: Reduce unnecessary background work by skipping many fetches when the tab is hidden, and refresh dashboard-specific data on visibility change to ensure UI updates after OAuth or tab switch.
- webui/static/style.css: Replace glassmorphic backdrop-filters with opaque dark gradients for sidebar and main content to improve GPU rendering and visual consistency.
Overall: Adds reliable post-download album repair scanning using multiple metadata sources and reduces unnecessary client polling and heavy CSS effects for better performance and robustness.
Add full-featured SpotifyWorker and iTunesWorker background workers to enrich artists, albums, and tracks with external metadata using batch cascading searches, fuzzy name matching, ID validation, and DB backfills. Update RepairWorker to re-read the transfer path from the database each scan, resolve host paths when running in Docker, and trigger immediate rescans when the transfer path changes; remove the static config_manager dependency. Also include supporting changes to the database layer and web UI/server (stats, controls, and styles) to integrate the new workers and reflect updated worker status.
Add _get_playlist_items_page to call the new playlists/{id}/items endpoint (Feb 2026 API migration) and fall back to spotipy.playlist_items (old /tracks) on 403/404. Update _get_playlist_tracks and web_server.get_playlist_tracks to use the new helper to avoid 403 errors for Development Mode apps while preserving compatibility with Extended Quota Mode.
Introduce a RepairWorker to scan the transfer folder and automatically detect/repair broken album track numbers (e.g. the "all tracks = 01" bug). The worker uses mutagen to read/write tags, fuzzy-matches titles against an album tracklist (Spotify/iTunes via a SpotifyClient), updates filenames and the tracks DB file_path when renamed, and caches album tracklists. It also adds DB schema support (repair_status, repair_last_checked, and an index).
Integrates the worker into the web server: initializes and starts the worker, and exposes /api/repair/status, /api/repair/pause and /api/repair/resume endpoints. Adds UI elements (button, tooltip), client-side JS to poll and control the worker, CSS for visuals/animations, and a new image asset (whisoul.png).
