- Cards reclassified from album to single/EP (via lazy track count)
now physically move from albums-grid to singles-grid
- Singles section auto-shows when cards move into it
- Add collectors edition to album title variation patterns — fixes
"Damn" not matching "DAMN. COLLECTORS EDITION." in library
- Both base-title-to-edition and edition-to-base variations now include
collectors edition alongside deluxe/platinum/special
- Fetch real track count from source during completion check when
total_tracks is 0 (Discogs masters) — one API call per album, runs
during existing per-album ownership check phase
- Reclassify album cards to single/EP when track count reveals 1-3/4-6
tracks — updates type label and data attribute in place
- Add collectors edition to album title variation patterns for matching
"Damn" against "DAMN. COLLECTORS EDITION." in library
- Hide 0/0 fraction when expected_tracks is 0, show proper count when
fetched
- New core/discogs_worker.py — background worker enriching artists and
albums with Discogs metadata following AudioDBWorker pattern exactly
- Artist enrichment: discogs_id, bio, members, URLs, image backfill,
genre backfill, summary backfill from bio
- Album enrichment: discogs_id, genres, styles (400+ taxonomy), label,
catalog number, country, community rating, image backfill
- DB migration: discogs columns on artists (id, match_status, bio,
members, urls) and albums (id, match_status, genres, styles, label,
catno, country, rating, rating_count)
- Worker initialization with pause/resume persistence
- Status/pause/resume API endpoints
- Integrated into enrichment status system, rate monitor, auto-pause
during downloads/scans, WebSocket status emission
- Add bit_depth, sample_rate, bitrate columns to track_downloads table
- Read audio info from file via Mutagen when recording provenance
- Source Info popover shows "Audio: 24-bit · 96.0kHz · 2304kbps"
- These values are captured from the original file before transcoding,
so users can see the original specs even after Blasphemy Mode converts
FLAC to lossy format
- Update provenance file_path when Blasphemy Mode deletes the original
FLAC and replaces it with a lossy copy — provenance now points to
the transcoded file instead of the deleted original
- New update_provenance_file_path() database method
- Non-blocking: wrapped in try/except, never interrupts transcode flow
- Downsample (hi-res → CD quality) is unaffected — replaces in-place
with same filename, provenance stays valid
- Was only backfilling the active provider — artists added via Deezer
never got Spotify/iTunes IDs, and vice versa
- Now backfills iTunes (always), Deezer (always), and Spotify (if
authenticated) at the start of every scan
- Added _match_to_deezer() and update_watchlist_deezer_id() for
Deezer cross-provider matching
- Generalized backfill with provider→attribute/function maps
- New discovery_artist_blacklist table with NOCASE name matching
- Filter blacklisted artists from all 6 discovery pool queries, hero
endpoint, and recent releases via SQL subquery and Python set check
- Name-based filtering means one block covers all sources (Spotify/iTunes/Deezer)
- Hover any discovery track row → ✕ button to quick-block that artist
- 🚫 button on Discover hero opens management modal with search-to-add
(powered by enhanced search) and list of blocked artists with unblock
- CRUD API: GET/POST/DELETE /api/discover/artist-blacklist
- Updated changelogs
New track_downloads table records every download with full source data:
service type (soulseek/youtube/tidal/etc), username, remote filename,
file size, and audio quality. Recorded at all 3 post-processing
completion points.
Source Info button (ℹ) on each track in the enhanced library view shows
a popover with download provenance: service, username, original filename,
size, quality, download date. Includes "Blacklist This Source" button
that stores the real username+filename (not guessed local filenames).
Removed broken "Delete & Blacklist" option from Smart Delete since it
had no access to real source data. Blacklisting now done exclusively
from the Source Info popover where actual provenance data exists.
Added blacklist CRUD API endpoints (GET/POST/DELETE /api/library/blacklist).
Track delete in the enhanced library now shows three options:
- Remove from Library: DB record only (existing behavior)
- Delete File Too: DB + os.remove() the file from disk
- Delete & Blacklist: DB + file removal + add source to blacklist
New download_blacklist table stores rejected sources (username + filename)
with CRUD methods. Blacklist will be checked by the download pipeline
and the upcoming track redownload modal.
Smart delete modal styled with the same glass/dark theme as other
SoulSync modals, with color-coded destructive options.
New "Server Playlists" tab (default on Sync page) lets users compare
mirrored playlists against their media server and fix match issues.
- Dual-column comparison: source tracks (left) vs server tracks (right)
- Smart matching: exact title first, then fuzzy artist+title (≥75%)
- Find & Add: search library to fill missing slots at correct position
- Swap: replace matched tracks with different versions
- Remove: delete tracks from server playlists with confirmation
- Title similarity percentage badge on each match
- Disambiguation modal when multiple mirrored playlists share a name
- Album art on source tracks, server tracks, and search results
- Cross-column click-to-scroll highlighting
- Filter buttons (All/Matched/Missing/Extra) with live counts
- Escape key and backdrop click to close modals
- Mobile responsive (stacked columns under 768px)
- Works with Plex, Jellyfin, and Navidrome
Sync operations now store per-track data (name, artist, match status,
confidence, download status) in a new track_results column on
sync_history. Also fixed missing config_manager import in
add_to_wishlist that crashed the duplicate tracks toggle.
Same song from different albums was blocked from entering the
wishlist by a name+artist dedup check. Added toggle in Settings →
Library → File Organization: "Allow duplicate tracks across albums"
(on by default). When enabled, the dedup is skipped — different
album versions of the same song can coexist in the wishlist for
complete discography downloads. The UNIQUE constraint on track ID
still prevents the exact same track from being added twice.
mirror_playlist() was deleting all tracks and re-inserting them,
which wiped the extra_data containing discovery results. Now saves
the {source_track_id: extra_data} map before deleting and restores
it on re-insert for tracks that don't bring their own extra_data.
This prevents discovery loss when playlists auto-refresh on tab load.
"Believe" was falsely matching "Believe In Me" because SequenceMatcher
gives high scores when the search string is fully contained in the
match. Added a length ratio penalty: when cleaned titles differ in
length by more than 30%, the similarity score is multiplied by the
ratio (min/max length). This crushes prefix/suffix false positives
while leaving exact matches and cleaned variants (remastered, deluxe)
unaffected.
Apple Music returns censored titles like "B*****t Faucet" for
"Bullshit Faucet". The string similarity function now detects
asterisk patterns and matches by comparing non-censored words
exactly and censored words by prefix/suffix characters.
Only fires when * is present in one string — zero impact on
normal comparisons. Prevents daily re-downloads of explicit
tracks that exist in the library under their uncensored names.
When artist-specific track search fails, falls back to album-aware
matching: finds the album by title (any artist), then checks if the
track exists on it. Fixes daily re-downloads of collaborative albums
filed under a different artist (e.g., "Spiral Staircases" tagged
under "The Alchemist" but scanned from "Larry June's" watchlist).
- check_track_exists: new album parameter, album-aware fallback with
0.8 album title threshold + 0.7 track title threshold
- Watchlist scanner: passes album_data.get('name') to track checks
- Download modal: passes batch_album_context to fallback track search
- Wishlist callers (4 spots): extract and pass track album name
- Backwards compatible: album=None default, no change for callers
without album context (singles, playlists)
Completion accuracy:
- Exact match only: "Complete" requires owned_tracks >= expected_tracks,
no more 90% rounding that hid missing tracks
- Deduplicate track counting: DISTINCT (title, track_number) prevents
duplicate album entries from inflating owned count (e.g., 3 "GNX"
entries with 12+1+2 rows counted as 12 unique tracks, not 15)
- MAX(track_count) instead of SUM for stored count — uses largest
album entry rather than summing duplicates
- file_path IS NOT NULL filter ensures only real files are counted
- Frontend uses real numbers instead of overriding missing=0 when
backend says "completed"
Multi-artist albums:
- Title-only fallback search when artist-specific search fails
- Finds "Anger Management" filed under "The Alchemist" when checking
from Rico Nasty's page
- Same confidence scoring prevents false matches
New "Scan Lookback" dropdown in the watchlist artist config modal.
Each artist can override the global lookback period (7d to entire
discography). Default is "Use Global Setting" (NULL in DB).
- Database: lookback_days INTEGER DEFAULT NULL on watchlist_artists,
auto-migrated on startup
- Scanner: checks per-artist lookback_days first, falls back to
global discovery_lookback_period if NULL
- Backend: GET/POST /api/watchlist/artist/<id>/config includes
lookback_days. Changing lookback clears last_scan_timestamp to
force a rescan with the new window
- Frontend: dropdown with 8 options in artist config modal
- Fully backwards compatible — existing artists unchanged
Watchlist cards: removed spring-bounce transitions, staggered
animations, and multi-layer hover shadows. Added CSS containment
and will-change for smoother scrolling.
Recent releases: backfill missing album cover art on page load
via metadata source lookup. Persists found covers to database.
Two bugs preventing Deezer artist images in the watchlist:
1. web_server.py: The image fetch called get_artist() which doesn't
exist on DeezerClient. Replaced with direct Deezer API call for
picture_xl — simple and reliable.
2. music_database.py: update_watchlist_artist_image() only matched
spotify_artist_id and itunes_artist_id in the WHERE clause.
Deezer artists use deezer_artist_id, so the UPDATE matched zero
rows and the image was never saved. Added deezer_artist_id to
the WHERE clause.
New algorithm: pick first track alphabetically from artist's library, search
both Deezer and iTunes APIs for 'artist track' to find the exact artist,
verify name matches, then use max(deezer_id, itunes_id) as the canonical
differentiator. Deterministic across instances — any SoulSync with the same
artist and at least one matching track will produce the same soul_id.
Fallback chain: canonical API ID → first album title → name only.
Migration clears all artist soul_ids on first v2.1 startup for regeneration.
- Stats page: database storage donut chart with per-table breakdown and total size
- Discover page: 5 new sections mined from metadata cache (zero API calls):
Undiscovered Albums, New In Your Genres, From Your Labels, Deep Cuts, Genre Explorer
- Genre Deep Dive modal: artists (clickable → artist page), popular tracks,
albums with download flow, related genre pills, in-library badges
- All cache queries filtered by active metadata source (Spotify/iTunes/Deezer)
- Stale cache entries (404) gracefully fall back to name+artist resolution
- Album cards show "In Library" badge, artist avatars scaled by prominence
Full stats dashboard that polls Plex/Jellyfin/Navidrome for play
history and presents it with Chart.js visualizations:
Backend:
- ListeningStatsWorker polls active server every 30 min
- listening_history DB table with dedup, play_count/last_played on tracks
- get_play_history() and get_track_play_counts() for all 3 servers
- Pre-computed cache for all time ranges (7d/30d/12m/all) rebuilt each sync
- Single cached endpoint serves all stats data instantly
- Stats query methods: top artists/albums/tracks, timeline, genres, health
Frontend:
- New Stats nav page with glassmorphic container matching dashboard style
- Overview cards (plays, time, artists, albums, tracks) with accent hover
- Listening timeline bar chart (Chart.js)
- Genre breakdown doughnut chart with legend
- Top artists visual bubbles with profile pictures + ranked list
- Top albums and tracks ranked lists with album art
- Library health: format breakdown bar, unplayed count, enrichment coverage
- Recently played timeline with relative timestamps
- Time range pills with instant switching via cache
- Sync Now button with spinner, last synced timestamp
- Clickable artist names navigate to library artist detail
- Last.fm global listeners shown alongside personal play counts
- SoulID badges on matched artists
- Empty state when no data synced yet
- Mobile responsive layout
DB migrations: listening_history table, play_count/last_played columns,
all with idempotent CREATE IF NOT EXISTS / PRAGMA checks.
- Add get_artist_top_tracks to Last.fm client (up to 100 tracks)
- Include lastfm_listeners, lastfm_playcount, lastfm_tags, lastfm_bio,
and soul_id in artist detail API response
- New endpoint: /api/artist/<id>/lastfm-top-tracks for lazy loading
- Hero layout: image (160px) | center (name, badges, genres, bio,
listener/play stats, progress bars) | right card (scrollable top
100 tracks from Last.fm)
- Badges 36px with hover lift, bio in subtle card with Read More
toggle, Last.fm tags merged with existing genres
- Numbers formatted: 1234567 → 1.2M
- Graceful degradation: sections hidden when Last.fm data unavailable
SoulID worker generates deterministic soul IDs for all library entities:
- Artists: hash(name + debut_year) — searches iTunes + Deezer APIs,
verifies correct artist by matching discography against local DB
albums via MusicMatchingEngine, pools years from both sources and
picks the earliest. Falls back to hash(name) if no match found.
- Albums: hash(artist + album)
- Tracks: song ID hash(artist + track) + album ID hash(artist + album + track)
Dashboard button with trans2.png logo, rainbow spinner, hover tooltip.
Worker orb with rainbow effect. SoulSync badge on library artist cards.
DB migration adds soul_id columns with indexes to artists/albums/tracks.
Migration version flag auto-resets artist soul IDs when algorithm changes.
DB migration adds 11 columns to profiles table for per-profile Spotify
credentials, Tidal tokens, and media server library selection. All
encrypted, all default NULL (fall back to global config).
API endpoints follow existing ListenBrainz per-profile pattern:
- GET/POST/DELETE /api/profiles/me/spotify
- GET/POST /api/profiles/me/server-library
Foundation only — no frontend UI or client initialization changes yet.
Preflight: hash track IDs before syncing and compare against last sync.
Skip only if exact same tracks were already synced and all matched.
Replaces the old count-based smart-skip which could miss track swaps.
Sync history: update existing entry for same playlist_id instead of
creating duplicates. Re-syncing the same playlist now refreshes the
existing row with new timestamps and stats.
If album info is missing, not a dict, or named "Unknown Album",
it gets repaired using the track name as fallback instead of
storing junk display data.
INSERT OR REPLACE on existing tracks was deleting the entire row and
reinserting only 9 columns, nuking spotify_track_id, deezer_id, isrc,
bpm, musicbrainz IDs, and ~15 other enrichment columns every scan.
Now uses UPDATE for existing tracks (preserves all enrichment) and
INSERT only for new tracks. Also ensures file_path gets updated from
the media server on each scan, fixing stale paths for users whose
files were moved/reorganized.
- New sync_history DB table tracks last 100 syncs with full cached context
- Records history for all sync types: Spotify, Tidal, Deezer, YouTube,
Beatport, ListenBrainz, Mirrored playlists, and Download Missing flows
- Sync History button on sync page with modal showing entries, source
filter tabs, stats badges, and pagination
- Re-sync button: server syncs expand card inline with live progress bar,
matched/failed counts, and cancel button; download syncs open download modal
- Re-syncs update the original entry (moves to top) instead of creating duplicates
- Delete button (x) on each entry with smooth remove animation
- Fix mirrored playlist source detection (youtube_mirrored_ matched youtube_)
- Fix broken server import thumbnails with URL validation
- Switch user automations to 2-column grid layout (matches system automations)
- Add duplicate button on non-system cards with POST /api/automations/<id>/duplicate
- Add search/filter bar (text search + trigger/action dropdowns) shown at 6+ automations
- Add Inspiration section with 8 starter templates that pre-fill the builder
- Add folder-style automation grouping with group_name DB column, dropdown
popover for assignment, collapsible group sections, and builder group input
- 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
Both NOT NULL and profile v2 migrations now include album_deezer_id and
artist_deezer_id columns, use safe shared-column data copy instead of
SELECT *, and add album_deezer_id to UNIQUE constraints.
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
New library_history table logs every completed download and every new
track imported from Plex/Jellyfin/Navidrome. A "History" button next
to "Recent Activity" on the dashboard opens a modal with Downloads and
Server Imports tabs, album art thumbnails, quality/source badges, and
pagination.
- Watchlist nullable migration now preserves profile_id column and composite
UNIQUE constraints when rebuilding the table
- Profile support migration always repairs missing profile_id columns on all
tables, even if the migration metadata key already exists (handles tables
rebuilt by other migrations)
- Confirm dialog z-index raised to 100000 to appear above profile picker
overlay (99999), fixing invisible delete confirmation
The migration to make spotify_artist_id nullable was using fragile string
matching against CREATE TABLE SQL, which silently failed for some databases.
Now uses PRAGMA table_info to reliably detect the NOT NULL flag.
Automatically mirrors every parsed playlist (Spotify, Tidal, YouTube, Beatport) to a local database so they're always accessible — even if a service subscription lapses or the browser closes.
- New "Mirrored" tab on the Sync page with source-branded cards showing discovery/download status
- Auto-mirrors on successful parse (upsert — re-parsing updates the existing mirror, no duplicates)
- Click any mirrored playlist to browse its full track list, then run it through the discovery pipeline
- Cards dynamically reflect live state: Discovering → Discovered → Downloading → Downloaded
- Download modal rehydrates after page refresh — click a "Downloading..." card to resume viewing progress
- All phase transitions (start, complete, cancel, error, modal close) keep card and backend state in sync
- Profile-scoped via profile_id, consistent with other features
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.
- 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.
Add support for cycling hero/featured similar artists by introducing a last_featured timestamp and using it to prefer least-recently-featured artists. Changes include:
- DB migration: add _add_similar_artists_last_featured_column and call it during migrations to add a last_featured TIMESTAMP column (non-fatal on error).
- Query changes: get_top_similar_artists now excludes watchlist artists via a LEFT JOIN and wa.id IS NULL and orders results by last_featured (nulls first), then by last_featured asc, occurrence_count desc, and similarity_rank asc. The query aliasing was also added for clarity.
- New helper: mark_artists_featured updates similar_artists.last_featured = CURRENT_TIMESTAMP for shown artists.
- Web server: increase fetch limit to 50, remove random shuffle and instead take the top 10 (already ordered by cycling logic), and call mark_artists_featured to rotate featured artists.
These changes aim to provide deterministic, least-recently-shown cycling of hero artists while keeping watchlist artists out of recommendations.
Prefer an album's stored track count when owned_tracks meets or exceeds it (avoids marking a complete standard edition as incomplete when an external source reports a larger deluxe count). Add more robust edition-detection regexes and generic catch-alls (parenthesized/bracketed text containing "edition") in music_database.py and web_server.py, and include silver/gold/platinum edition variants. Also tidy related regex handling and comments to improve matching for varied edition naming (e.g. "MMXI Special Edition").
Introduce a new Retag tool to track and re-tag previously downloaded albums/singles. Changes include:
- Database: add migration hook and create retag_groups and retag_tracks tables, indexes, and many helper methods (add/find/update/delete groups & tracks, stats, trimming).
- Backend (web_server): capture completed album/single downloads into the retag tables, implement retag execution logic (_execute_retag) to fetch album metadata, match tracks, update tags, move files, download cover art, and update DB. Add thread-safe globals, executor, and REST endpoints for stats, listing groups, group tracks, album search, execute, status, and delete.
- Frontend (webui): add Retag Tool card, modals, search UI, JS to list groups/tracks, search albums, start retag operations, poll status, and update UI; include help content. Add CSS for modals and components.
The migration is invoked during DB init to ensure existing installations create the new tables. The tool caps stored groups (default 100) and avoids duplicate track entries.
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 per-track selection checkboxes, select-all control and a selection count to download modals (missing/YouTube/Tidal/artist-album). Implement JS helpers (toggleAllTrackSelections, updateTrackSelectionCount) to manage checkbox state, row dimming, button disabling, and to filter/stamp selected tracks with _original_index before sending to the backend. Update start/add-to-wishlist flows to use only selectedTracks and disable controls once analysis starts. Backend _run_full_missing_tracks_process now reads _original_index to preserve original table indices in analysis results. CSS updates (mobile.css and style.css) add styling for checkbox columns, responsive hiding logic for headers/columns, selection visuals (.track-deselected), and small layout/width tweaks.
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.
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.
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).
