Across all background workers (Spotify/Tidal/Deezer/Qobuz/iTunes/
Discogs/Genius/AudioDB/MusicBrainz/Last.fm/SoulID + the metadata-update
worker) and the repair-job scanners. All converted to
`logger.debug("...: %s", e)`.
Two `_e` renames in genius_worker and soulid_worker where outer scope
was already binding `e`. Two finally-block sites in repair_jobs/
library_reorganize.py left silent (conn.close on shutdown path).
Refs #369
- collapse old multi-line debug bursts into single structured rows
- remove leftover DEBUG-style prefixes from message text
- keep the app log readable without losing useful trace detail
- Add interruptible stop events to background workers so shutdown
wakes out of long sleeps instead of waiting on fixed delays.
- Stop scan managers, repair worker, executors, and cleanup helpers
deterministically so process exit does not leave background threads
alive.
- Add startup warnings for stale SQLite WAL/SHM sidecars so unclean
shutdowns are easier to spot before init/migration errors cascade.
- Prevent forced kills from leaving SQLite sidecars behind, which
made rollbacks to older branches fail with malformed database
errors.
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.
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)

DB migration adds soul_id columns with indexes to artists/albums/tracks.
Migration version flag auto-resets artist soul IDs when algorithm changes.
