Two-part fix to the Your Albums "Download Missing" flow on Discover.
Part A — UX redesign
The prior `downloadMissingYourAlbums()` ran a per-album loop that
fired direct-download tasks via `openDownloadMissingModalForYouTube`.
Reported as silently failing — "Queuing 2/2" toast with no actual
transfer activity. Even when downloads worked, bypassing the
wishlist meant no retry / dedup / rate-limit / source-fallback
handling.
Replaced with a selectable-grid modal mirroring the Download
Discography pattern from the library page. Click the download
button → opens a checkbox grid showing every missing album (cover,
title, artist, year, track count, source) → user picks what they
actually want → click "Add to Wishlist" → each album's tracks get
resolved + queued through the existing wishlist auto-download
processor. NDJSON progress stream renders ✓/✗ per album.
New JS helpers:
- `_openYourAlbumsBatchModal(missingAlbums)` — builds the modal
- `_renderYourAlbumsBatchCard(row, index)` — per-album card
- `_yourAlbumsBatchSelectAll(select)` — bulk toggle
- `_updateYourAlbumsBatchFooterCount()` — live count + button text
- `_closeYourAlbumsBatchModal()` — overlay teardown
- `_startYourAlbumsBatchAddToWishlist()` — submit handler, NDJSON
progress consumer
- `_yourAlbumsPickSource(album)` — picks the single best source-id
per row (priority: spotify → deezer → tidal → discogs)
Reuses the `.discog-*` CSS classes from the library Download
Discography modal — no new CSS. Reuses the existing
`/api/artist/<id>/download-discography` endpoint. The endpoint's URL
artist_id param is functionally unused (per-album payload carries
everything — verified by reading the endpoint body), so the modal
posts with placeholder `your-albums` and gets multi-artist
resolution for free without backend changes.
Part B — Tidal album resolution
Reported as the original bug: clicking download on Tidal-only albums
did nothing because `/api/discover/album/<source>/<album_id>` had no
`tidal` branch and `tidal_client` had no `get_album_tracks` method.
`core/tidal_client.py`: new `get_album_tracks(album_id, limit=None)`
method. Two-phase: cursor-walk
`/v2/albums/<id>/relationships/items?include=items` for track refs +
position metadata (`meta.trackNumber` + `meta.volumeNumber`),
batch-hydrate via existing `_get_tracks_batch` for artist/album
names. Returns `Track` objects with `track_number` and `disc_number`
attached. Sort by (disc, track) so multi-disc compilations render in
album order.
`web_server.py`: new `'tidal'` source branch in
`/api/discover/album/<source>/<album_id>`. Resolves album metadata
via `get_album`, tracks via `get_album_tracks`, cover art via inline
`?include=coverArt` lookup. Same response shape as Spotify/Deezer
branches.
`webui/static/discover.js`:
- `tidal_album_id` added to `trySources` for the single-album click
flow (`openYourAlbumDownload`)
- Same source picker drives the new batch modal
- Virtual-id generation includes `tidal_album_id` so Tidal-only
albums get stable identifiers across discover-album-* / your-
albums-* contexts
10 new tests in `tests/test_tidal_album_tracks.py` pin:
- Single-page walk + hydration
- Multi-page cursor chain
- Multi-disc sort order (disc 1 → 2 in track order each)
- `limit` short-circuit at page boundary
- No-token short-circuit (no API call)
- HTTP error returns empty
- 429 raises (propagates to `rate_limited` decorator for retry)
- Forward-compat type filter (skips non-track entries)
- Partial-batch hydration failure containment
- Empty-album short-circuit (no batch call)
Full pytest: 2693 passed.
Follow-up to the prior compilation-album scanner fix. That patch
made the scanner read `tracks.track_artist` (per-track artist
column) via COALESCE so compilation tracks would compare against
the right value. But tracks downloaded BEFORE the `track_artist`
column existed have track_artist=NULL — COALESCE falls back to
album artist (the curator) and the wrong-comparison case returns.
Fix: explicit 3-tier resolution in `_scan_file`:
1. DB `tracks.track_artist` if populated → trust it. Respects
manual edits from the enhanced library view (user who curated
the DB value but didn't re-tag the file gets their edit
respected, not overridden by stale file tag).
2. File's ARTIST tag via mutagen if present → use it. Tidal /
Spotify / Deezer all write the per-track artist into the
audio file at download time regardless of SoulSync's DB
schema, so it's ground truth even when the DB column is
stale or NULL. File is already open for fingerprinting so
mutagen tag-read is essentially free.
3. Album artist → final fallback for files without proper ARTIST
tags AND no DB track_artist. Existing pre-fix behavior.
`_load_db_tracks` SELECT now surfaces `track_artist` (raw, may be
empty/NULL via NULLIF) and `album_artist` separately in addition
to the COALESCE'd `artist` field — so `_scan_file` can tell the
difference between 'DB has a curated value' and 'DB fell back to
album artist'. Without this distinction, the file-tag fallback
would create false positives when DB is curated but file is stale.
5 new tests (11 total in the file) pin:
- File-tag-trumps-DB resolves the legacy NULL case (DB says
'Andromedik' (album curator), file says 'Eclypse', AcoustID
says 'Eclypse' → no flag)
- Tag-missing falls back to album artist (preserves existing
genuine-mismatch contract — file without tag + AcoustID
mismatch still flags)
- Mutagen exception swallowed (debug log, fall-through)
- File-tag matches DB → no behavioral change
- DB curated value trumps stale file tag (false-positive guard
— user edited DB without re-tagging file shouldn't get flagged)
Two existing test fixtures (`_make_context` callers) updated to
the new 10-column row shape.
SQL behavior verified empirically against real SQLite: NULL and
empty-string both flow through NULLIF → None in Python →
file-tag-fallback path. Modern populated values trump file tag.
Discord: Discover → Your Albums (and Your Artists) was returning
nothing for Tidal users regardless of how many albums/artists they'd
favorited. Audit found `get_favorite_albums` and `get_favorite_artists`
called the deprecated `/v2/favorites?filter[type]=ALBUMS|ARTISTS`
endpoint — that endpoint returns 404 for personal favorites because
it's scoped to collections the third-party app created itself. The
V1 fallback (`/v1/users/<id>/favorites/...`) is also dead because
modern OAuth tokens carry `collection.read` instead of the legacy
`r_usr` scope V1 demands (returns 403).
Same root cause as the favorited-tracks fix from #502.
Fix: rewire to the working V2 user-collection endpoints —
`/v2/userCollectionAlbums/me/relationships/items` and
`/v2/userCollectionArtists/me/relationships/items` — using the
same cursor-paginated pattern shipped for tracks.
Architecture:
* ID enumeration lifted into a generic
`_iter_collection_resource_ids(path, expected_type, max_ids)`
helper so tracks / albums / artists all share one walker. Three
thin wrappers preserve the per-resource public surface
(`_iter_collection_track_ids`, `_iter_collection_album_ids`,
`_iter_collection_artist_ids`). Net deduped ~80 lines that would
otherwise be three near-identical copies.
* Batch hydration via `/v2/{albums|artists}?filter[id]=...&include=...`
with extended JSON:API include semantics. One request returns up
to 20 albums + their artists + cover artworks all in `included[]`
(or 20 artists + their profile artworks). Three static helpers
parse the response:
- `_build_included_maps(included)` → indexes the array by type
so per-resource lookup is O(1) per relationship ref
- `_first_artist_name(rels, artists_map)` → resolves primary
artist from relationships block; '' on missing/unknown
- `_first_artwork_url(rel, artworks_map)` → picks `files[0]`
(Tidal returns artwork files largest-first, so this gets the
highest-resolution variant — typically 1280×1280)
* Public methods (`get_favorite_albums`, `get_favorite_artists`)
preserve the prior return shape — list of dicts matching what
`database.upsert_liked_album` / `upsert_liked_artist` consume —
so the discover aggregator path in `web_server.py` stays
byte-identical. No caller changes needed.
* Deleted ~240 lines of dead code: the V2-favorites paths AND the
V1 fallback paths from the old method bodies. Both are dead
against modern OAuth tokens.
24 new tests in `tests/test_tidal_favorite_albums_artists.py` pin:
* Cursor-walker dispatch (album/artist iters pass correct path +
expected_type to the generic walker)
* Included-map building (groups by type, skips items missing id)
* Artist + artwork relationship resolution (full + missing rels +
unknown id + no files cases)
* Batch hydration parse for albums (full attributes, missing
relationships fall through to defaults, type-filter excludes
non-album entries, `filter[id]` param is comma-joined)
* Batch hydration parse for artists (same shape coverage)
* End-to-end orchestrator behavior (walk → batch → return,
empty-input short-circuits without API call, BATCH_SIZE chunking
on 41 IDs → 20/20/1, exception-from-iter returns [])
Endpoint paths empirically verified against live Tidal API:
`userCollectionArtists/me/relationships/items` returned 200 + 5
real artist refs for the test account. `userCollectionAlbums/...`
returned 200 + empty (account has 0 album favorites currently)
but the response shape is correct. The deprecated
`/v2/favorites?filter[type]=ALBUMS` returned 404. The V1
`/v1/users/<id>/favorites/albums` returned 403 with explicit
"Token is missing required scope. Required scopes: r_usr" message.

Discord report (CJFC, 2026-04-26): syncing a Spotify playlist to the
server overwrote anything manually added to the server-side playlist.
The fix adds a per-sync mode picker next to the Sync button on the
playlist details modal — Replace (default, current delete-recreate
behavior) or Append only (preserves existing tracks, only adds new
ones). Useful when the source platform caps playlist size and the
user is manually building beyond it on the server.
Implementation:
* New `append_to_playlist(name, tracks)` method on Plex / Jellyfin /
Navidrome clients. Each uses the server's NATIVE append API:
- Plex: `existing_playlist.addItems(new_tracks)`
- Jellyfin: `POST /Playlists/<id>/Items?Ids=...&UserId=...`
- Navidrome: Subsonic `updatePlaylist?songIdToAdd=...`
Falls back to `create_playlist` when the playlist doesn't exist
yet (first sync). No delete-recreate, no backup playlist created
(preserves playlist creation date + metadata + non-soulsync-managed
tracks).
* Dedup-by-server-native-id (ratingKey for Plex, GUID for Jellyfin,
song-id for Navidrome) — never re-adds a track already on the
playlist. Server-native identity, not fuzzy title+artist match,
so it can't false-collide.
* `sync_service.sync_playlist` accepts `sync_mode='replace'|'append'`
kwarg. Single if/else branch dispatches to `append_to_playlist` or
`update_playlist`. Threaded through `core/discovery/sync.run_sync_task`
and the `/api/sync/start` HTTP handler. Validation on the API rejects
unknown mode strings (defaults to 'replace').
* Frontend: per-playlist `<select id="sync-mode-${id}">` rendered next
to the Sync button in both modal renderers (sync-spotify.js for
Spotify playlists, sync-services.js for Deezer ARL playlists).
`startPlaylistSync` reads the select at click time; missing select
(other callers like discover.js) defaults to 'replace' so backward
compat preserved without per-call-site updates.
* SoulSync standalone has no playlist methods at all and the modal
hides the Sync button entirely on it via `_isSoulsyncStandalone` —
dispatch never reaches that path, no defensive fallback needed.
15 new tests pin per-server append behavior:
- missing playlist → create_playlist delegation
- dedup filtering (existing IDs skipped, only new tracks added)
- empty new-track set short-circuits without API call
- failure paths return False without raising
- contract listing (KNOWN_PER_SERVER_METHODS includes
'append_to_playlist'; Plex / Jellyfin / Navidrome all implement)
Plus tests/discovery/test_discovery_sync.py fake `sync_playlist`
fixture got `sync_mode='replace'` default to match the new signature
(was breaking after the kwarg add; now passing).

Closes CJFC discord request.
Adds the user's Tidal favorited tracks ("My Collection" in the Tidal
app) as a virtual playlist alongside their real playlists, mirroring
how Spotify's "Liked Songs" is treated.
Reporter (yug1900) located the working endpoint after the prior
`/v2/favorites?filter[type]=TRACKS` attempt returned empty data —
that endpoint is scoped to collections the third-party app created
itself, not personal favorites. Real endpoint:
GET /v2/userCollectionTracks/me/relationships/items
?countryCode=US&locale=en-US&include=items
Cursor-paginated (20 per page, follow `links.next` with
`page[cursor]=...` until exhausted). Response only carries
track-level attributes — artist + album NAMES come back as
relationship-link stubs, not embedded data.
Implementation:
* Two-phase fetch — `_iter_collection_track_ids` walks the cursor
chain to enumerate every track id (cheap, IDs only), then
`get_collection_tracks` batch-hydrates 20 IDs at a time through
the existing `_get_tracks_batch` helper which already knows how
to `include=artists,albums`. No duplication of the JSON:API
artist/album parse, no new dataclass shape.
* Virtual playlist `tidal-favorites` appended to the end of
`/api/tidal/playlists`. ID intentionally has no colon —
sync-services.js renderer interpolates IDs into CSS selectors
via template literals (`#tidal-card-${p.id} .foo`) and a `:`
would parse as a CSS pseudo-class operator.
* `tidal_client.get_playlist("tidal-favorites")` recognizes the
virtual id and dispatches to the collection path internally, so
every per-id consumer gets it for free: detail endpoint, mirror
auto-refresh automation, "build Spotify discovery from Tidal
playlist" flow.
OAuth scope expansion:
* Added `collection.read` to both OAuth flows (the
`core/tidal_client.py::authenticate` standalone path AND the
`web_server.py::auth_tidal` web flow — they were independent
scope strings that both needed updating).
* Added `prompt=consent` to both flows — without it Tidal silently
returns a token carrying only the ORIGINAL scope set even after
re-authentication, because Tidal treats the existing
authorization as still valid.
* New `disconnect()` method + `POST /api/tidal/disconnect`
endpoint + Disconnect button next to Authenticate in Settings →
Connections → Tidal — required for users whose existing token
predates the scope expansion (forces a clean grant).
Reconnect-needed UI hint:
* `_collection_needs_reconnect` flag set on 401/403 from the
collection endpoint, cleared on next successful walk, NOT set
on 5xx (transient server errors must not falsely tell the user
to reconnect).
* Listing endpoint reads the flag and surfaces a placeholder card
titled "Favorite Tracks (reconnect Tidal to enable)" with a
description pointing at Settings, so the user has something
visible to act on instead of a silently missing row.
Diagnostic logging — collection request URL + response status +
first 300 bytes of body now logged at info level so future "why
is my collection empty" reports can be diagnosed from app.log
without needing live reproduction.
22 new tests pin: cursor walk (full chain, max-ids cap mid-page +
at page boundary), auth gates (no token / 401 / 403 all bail
clean), reconnect-flag lifecycle (set on 401/403, cleared on next
successful walk, NOT set on 5xx), forward-compat type filter
(non-track entries skipped), count helper, batch hydration
delegation + chunking at the 20-per-batch cap, partial-batch
failure containment, virtual-id dispatch (real playlist ids still
flow through the normal path).
Closes#502.
Phase B of foxxify discord report. Pre-#524 manual-import bug left
some albums in the library with `artist=Unknown Artist` and `album.title
= <numeric album_id>`. Reorganize couldn't place them (no usable
metadata source ID) and emitted a generic "run enrichment first" hint
that doesn't apply — enrichment can't fix these rows. The right tool
is the existing `Fix Unknown Artists` repair job (reads file tags,
re-resolves metadata, re-tags + moves files).
Discoverability gap, not a logic gap. Reorganize now detects the bad-
metadata shape (Unknown Artist OR album.title that's a 6+ digit
numeric id) and emits a clear "run the Fix Unknown Artists repair
job" hint at both reason-emit sites (planner + executor). No
duplication of fixer logic.
WHATS_NEW entry covers both Phase A (orphan-format sibling handling,
already committed in d944a16) and Phase B since they ship in the same
PR for the same reporter.
20 new tests pin helpers + reason routing.
Discord report (Foxxify): users with the lossy-copy feature enabled
have `track.flac` AND `track.opus` side-by-side in their library.
Reorganize is DB-driven and only knows about ONE file per track
(the lossy copy). The other format used to get left behind in the
old location while the canonical moved to its new destination.
Empty-folder cleanup never fired because the source dir still had
audio.
# What was happening
1. User downloads album → SoulSync transcodes `.flac` → `.opus`,
embeds `.lrc` lyrics
2. DB row points at `.opus` (the lossy library copy)
3. User runs Library Reorganize
4. Reorganize moves `.opus` to new template path → `Artist/Album/01 Track.opus`
5. `.flac` orphan stays at old location, `.lrc` follows `.opus`
6. Source dir still has the `.flac` → cleanup skips → empty folders pile up
# Fix
`_finalize_track` now finds sibling-stem audio files at the source
BEFORE removing the canonical and moves them to the same destination
dir, preserving both formats with the canonical's renamed stem.
Two new helpers in `core/library_reorganize.py`:
- `_find_sibling_audio_files(audio_path) -> list[str]` — returns
paths to other audio files at the same directory that share the
canonical's filename stem. Excludes the canonical itself, non-
audio extensions (sidecars handled separately by
`_delete_track_sidecars`), and different-stem tracks (different
songs in the same dir).
- `_move_sibling_to_destination(sibling_src, canonical_dst) -> str`
— moves a sibling-format file to the canonical's destination dir
with the canonical's renamed stem + the sibling's original
extension. Defensive — OS errors logged at warning, return None,
doesn't raise (caller treats as best-effort).
After the fix:
1. `.opus` → moved to new dir
2. `.flac` sibling detected → moved to same new dir with same stem
3. Source `.opus` removed, `.lrc` sidecar deleted from source
4. Source dir empty → cleanup proceeds normally
5. Both formats end up paired at the new location
# Tests added (11)
`tests/test_reorganize_orphan_format_handling.py`:
- Sibling detection: finds `.flac` when `.opus` is canonical (and
symmetric direction), excludes canonical itself, excludes
different-stem tracks, excludes non-audio (`.lrc`/`.nfo`),
finds multiple siblings (3+ formats), returns empty when source
dir missing
- Sibling move: renames to canonical stem + preserves sibling
extension, creates destination dir if missing, no-op when source
already at destination, returns None on OS failure (caller
treats as best-effort)
# Verification
- 11/11 new tests pass
- 97/97 reorganize-related tests pass total (no regression in
existing helpers)
- Ruff clean
# Follow-up in same PR
Next commit: cleanup repair job for legacy "Unknown Artist /
album_id" rows from the pre-#524 manual-import bug. Reorganize
correctly leaves those alone (they're DB-broken, not file-broken),
but a separate maintenance job to find + re-enrich them is needed.
Discord report (Skowl): downloaded a compilation album ("High Tea
Music: Vol 1") where every track has a different artist (Eclypse,
Andromedik, T & Sugah, Gourski, etc.) and the AcoustID scanner
flagged every single track as Wrong Song. The file tags had the
correct per-track artist (e.g. "Eclypse" for "City Lights"), but
the scanner compared against the album-level artist ("Andromedik",
the curator). Raw similarity 12% → Wrong Song flag.
# Why the prior multi-value fix didn't help
Foxxify's case (just-merged PR): AcoustID returned multi-value
credit "Okayracer, aldrch & poptropicaslutz!" — primary IS in the
credit. Splitting found it.
Skowl's case: both sides single-value but DIFFERENT artists.
Splitter has nothing to find — Eclypse simply isn't in "Andromedik".
Different bug.
# Cause
Scanner SQL at `core/repair_jobs/acoustid_scanner.py:281` joined
the `artists` table via `tracks.artist_id` which points at the
ALBUM artist (the curator/label-name applied to every row in a
compilation). The `tracks.track_artist` column already holds the
correct per-track artist for compilations — populated by every
server-scan path (Plex `originalTitle`, Jellyfin `ArtistItems`,
Navidrome per-track `artist`) AND the auto-import / direct-download
post-process flow (`record_soulsync_library_entry` writes it when
different from album artist). Scanner just wasn't reading it.
# Fix
```sql
SELECT t.id, t.title,
COALESCE(NULLIF(t.track_artist, ''), ar.name) AS artist,
...
```
Prefers per-track artist when populated, falls back to album artist
for legacy rows / single-artist albums where `track_artist` is NULL.
`NULLIF(t.track_artist, '')` handles the empty-string-instead-of-null
case some legacy rows might have.
# Composes with Foxxify's multi-value fix
For the rare compilation track where AcoustID ALSO returns a
multi-value credit (e.g. compilation track has multiple credited
performers), both paths work together — `track_artist` gives the
correct expected primary, then the helper splits the credit and
finds it.
# Tests added (2)
- `test_load_db_tracks_prefers_track_artist_for_compilation` —
reporter's exact case: track with `track_artist='Eclypse'` AND
`artist_id` pointing at album artist 'Andromedik' resolves to
'Eclypse'. Second track with NULL `track_artist` falls back to
album artist 'Andromedik' (single-artist + legacy compat).
- `test_load_db_tracks_falls_back_when_track_artist_empty_string`
— empty string in `track_artist` (some legacy rows) → NULLIF
returns NULL → COALESCE falls back to album artist.
Both use a real SQLite DB so the COALESCE/NULLIF logic + JOIN
runs against actual schema (SimpleNamespace fakes can't simulate
JOINs).
# Verification
- 6/6 scanner tests pass (2 new + 4 existing)
- 2586 full suite passes (+2 from prior commit)
- Ruff clean
Discord report (Foxxify): the AcoustID scanner repair job flagged
multi-artist tracks as Wrong Song because AcoustID returns the
FULL credit ("Okayracer, aldrch & poptropicaslutz!") while the
library DB carries only the primary artist ("Okayracer"). Raw
SequenceMatcher similarity scored ~43% — well below the 60%
threshold — so the scanner created a finding even though the
audio was correct. User couldn't fix without lowering the global
artist threshold to ~30% (which would let real mismatches through).
# Fix
Extended the shared `core/matching/artist_aliases.py::artist_names_match`
helper (originally lifted for #441) with credit-token splitting.
When the actual artist string contains common separators —
- punctuation: `,` `&` `;` `/` `+`
- keywords (whitespace-bounded): `feat.` `ft.` `featuring` `with`
`vs.` `x`
— the helper splits into individual contributors and checks each
against the expected artist. Primary-in-credit cases now resolve
at 100% instead of 43%.
Two pattern groups because punctuation separators don't need
surrounding whitespace, but keyword separators MUST be
whitespace-bounded — otherwise we'd split artists with `x` /
`with` etc. in their names ("JAY-X" → "JAY-" / "" issue).
Composes with the existing alias path: cross-script multi-artist
credits ("Hiroyuki Sawano" expected, "澤野弘之, FeaturedJp"
actual) work via alias-token-against-credit-token compare.
# Wire-in
Scanner at `core/repair_jobs/acoustid_scanner.py:202` replaces
the raw `SequenceMatcher` call with `artist_names_match`. Pass
RAW artist strings (not pre-normalised by `_normalize`) so the
splitter can recognise separators — `_normalize` strips ALL
punctuation, which destroyed the very tokens the splitter needs.
The AcoustID post-download verifier (`core/acoustid_verification.py`)
already routes through `_alias_aware_artist_sim` which calls the
same helper — gets the multi-value benefit automatically without
a separate wire-in.
# New `split_artist_credit` exported helper
Pure-function helper for callers who want token-level access to
the credit list (debugging, UI, future per-token enrichment). Same
splitter logic, exposed as a top-level function.
# Tests added (14)
`tests/matching/test_artist_aliases.py` (+11):
- `TestSplitArtistCredit` — parametrised across 12 credit-string
formats (comma, ampersand, semicolon, slash, plus, feat./ft./
featuring, with, vs., x, single-token, empty), drops empty
tokens, strips per-token whitespace
- `TestMultiValueCreditMatching` — reporter's exact case
(Okayracer in 3-artist credit → 100%), primary in middle/end of
credit, genuine-mismatch still fails, single-token actual falls
through to direct compare, multi-value composes with aliases,
threshold still respected
`tests/test_acoustid_scanner.py` (+3):
- Reporter's case end-to-end through `_scan_file` — fingerprint
99% / title 100% / multi-artist credit → no finding created
- Genuine artist mismatch still creates finding (no false
suppression of real mismatches)
- `JobResultStub` minimal scaffold for the integration tests
# Verification
- 14 new tests pass (49 helper + 5 scanner total in their files)
- 110 matching + scanner tests pass total
- 2584 full suite passes (+25 from baseline 2559)
- Ruff clean
- Reporter's exact case (Okayracer in `Okayracer, aldrch &
poptropicaslutz!`) now scores 100% match → no Wrong Song flag
Defensive followup. If Deezer CDN ever refuses the upgraded
1900×1900 URL for a specific album (rare — empirically tested 4
albums and none hit it), pre-fix would have succeeded with the
1000×1000 URL and post-fix would have failed entirely.
Both download sites now retry with the original URL when the
upgraded URL fails:
- `core/metadata/artwork.py::download_cover_art` — auto post-process
flow. Resolves the original URL from album_info / context the same
way the existing path does.
- `core/tag_writer.py::download_cover_art` — captures the original
URL before upgrade so the retry has it without a second context
lookup.
Strictly non-regressive: worst plausible post-fix case is now
identical to pre-fix (cover at 1000×1000 succeeds). Fallback only
fires on the rare CDN-refusal edge.
Tests added (2):
- `test_tag_writer_retries_with_original_on_failure` — upgraded URL
raises, original succeeds, both attempts logged in call order
- `test_tag_writer_no_fallback_for_non_dzcdn_url` — non-Deezer URLs
go through unchanged, no fallback path triggered (single attempt)
Verification:
- 18/18 helper + integration tests pass
- 2561 full suite passes
- Ruff clean
Discord report (Tim): downloaded cover art via Deezer metadata
source came out visibly blurry in Navidrome / on phones — large
displays exposed the limited resolution.
# Cause
Deezer's API returns `cover_xl` URLs at 1000×1000. The underlying
CDN actually serves up to 1900×1900 by rewriting the size segment
in the URL path (same trick the iTunes mzstatic + Spotify scdn
upgrades already use). SoulSync wasn't doing the rewrite — every
Deezer-sourced cover got embedded at 1000×1000 regardless of how
much higher resolution the CDN had available.
# Verified empirically
```
$ for size in 1000 1400 1800 1900 2000; do curl -I "...{size}x{size}-..."; done
1000: 200 OK 106 KB
1400: 200 OK 198 KB
1800: 200 OK 331 KB
1900: 200 OK 371 KB
2000: 403 Forbidden
```
1900 is the safe ceiling. Above that the CDN returns 403. CDN
serves source-native bytes when source < target (smaller-source
albums get same bytes whether we ask for 1000 or 1900), so asking
for 1900 universally is safe.
# Fix
New `_upgrade_deezer_cover_url(url, target_size=1900)` helper in
`core/deezer_client.py`. Pure function, mirrors the
`_upgrade_spotify_image_url` pattern that already lives in
`core/spotify_client.py`. Defensive on every input shape:
- Empty / None → returned as-is
- Non-Deezer URL (no `dzcdn`) → returned as-is
- No size segment in URL → returned as-is
- Already at/above target → returned as-is (idempotent, never
downgrades)
Applied at both cover-download sites:
- `core/metadata/artwork.py::download_cover_art` — auto post-process
flow. Mirrors the existing iTunes mzstatic upgrade right above it.
- `core/tag_writer.py::download_cover_art` — enhanced library view's
"Write Tags to File" feature.
# Scope discipline
- Helper applied at the DOWNLOAD boundary, not the source extraction
point in `deezer_client.py`. Means cached entries in the metadata
cache + DB row `image_url` columns keep the original 1000×1000 URL
Deezer's API returned. Future CDN behavior changes only affect the
download path, not stored data.
- Pre-existing `prefer_caa_art` toggle (Settings → Library →
Post-Processing) untouched — orthogonal workaround for users who
want even higher quality (MusicBrainz Cover Art Archive, often
3000×3000+).
- iTunes / Spotify upgrade paths untouched — they already worked.
# Tests added (16)
`tests/metadata/test_deezer_cover_url_upgrade.py`:
- Standard upgrade: default target 1900 on cover URL, alternate
dzcdn host (`e-cdns-images.dzcdn.net` vs `cdn-images.dzcdn.net`),
artist picture URLs (same path pattern), 500×500 source upgrades
too
- Custom target size: smaller target = no-op (never downgrade),
larger target works
- Idempotent: already at/above target returned unchanged
- Defensive on non-Deezer URLs: parametrised across 5 hosts
(Spotify scdn, iTunes mzstatic, MB CAA, Last.fm, random) — all
returned untouched
- Defensive on malformed Deezer URL (no size segment) → returned
as-is
- Empty / None handling
# Verification
- 16/16 helper tests pass
- 560/560 metadata + imports tests pass (no regression)
- 2559 full suite passes

Cin pre-review pass on the false-positive risk. Three tightenings:
# 1. Bumped MB-search trust threshold from 0.6 → 0.85
`MusicBrainzService.lookup_artist_aliases` previously trusted any
MB search match scoring ≥ 0.6 combined (name-similarity + MB
relevance). For distinctive cross-script artists the user-reported
case targets (Hiroyuki Sawano, Сергей Лазарев, etc.) real matches
score ~1.0 — well above 0.85. The 0.6 floor was loose enough to
let in moderate matches for ambiguous names, risking aliases for
the wrong artist getting cached + applied.
Bumped to 0.85. Tighter without rejecting any of the legit
cross-script cases the PR is for.
# 2. Ambiguity gate — skip when results within 0.1 of best
When MB search returns multiple results all scoring high (within
0.1 of the best), the artist name is ambiguous — common name with
multiple distinct artists ("John Smith" returning 10 different
John Smiths). Pulling aliases for any one of them risks the wrong
artist's data bridging incorrectly to a file's tag.
Added explicit ambiguity detection: when 2+ results within 0.1,
skip alias lookup entirely + cache empty. Matches Cin's
"explicit > implicit" — the prior code just picked the highest
score blindly.
# 3. Diagnostic log when alias rescues a comparison
When the alias path triggers a PASS that direct similarity would
have FAILed, emit an INFO log: `Artist alias rescued comparison:
expected='X' vs actual='Y' (direct sim=0.00, alias 'Z' →
score=1.00)`.
Lets future bug reports trace which alias triggered which decision.
Doesn't change behavior — visibility only. Logs ONLY the rescue
case, not happy-path direct matches (no log spam).

# Test infrastructure note
Logging tests use a directly-attached `ListHandler` on
`soulsync.acoustid.verification` (the actual logger name —
dot-separated by `get_logger`), NOT pytest's caplog. Same pattern
as the prior watchdog-test fix — caplog is intermittently flaky
in full-suite runs for soulsync namespace loggers. An owned
handler sidesteps both issues.

- Ruff clean
- Reporter's Japanese + Russian regression tests still pass —
legit cross-script case (sim ≈ 1.0) clears the new 0.85
threshold easily
Two perf gaps that would have failed Cin's review:
# Gap #1: alias lookup fired unconditionally
Pre-fix in this commit, `_resolve_expected_artist_aliases` ran at
the top of every `verify_audio_file` call regardless of whether
the direct artist match would have passed. For users whose library
is mostly same-script (95% of cases), every successful verification
was paying for a wasted DB query (and possibly a wasted MB API
call for un-enriched artists).
Restructured the helper to accept a callable provider instead of a
pre-resolved list. Provider invoked LAZILY only when direct
similarity falls below `ARTIST_MATCH_THRESHOLD`. Verifier passes a
memoising thunk that resolves once across the 3 comparison sites
within one verification.
`_alias_aware_artist_sim` now accepts `aliases` as either:
- iterable of strings (used eagerly — backward compat with tests
that already know the aliases)
- callable returning the iterable (resolved on first need within
a verification)
Happy path (direct match passes): zero DB queries, zero MB calls.
Cross-script case: one resolution shared across 3 sites — same as
the prior contract.
# Gap #2: existing-MBID artists never got alias backfill
Worker's `_process_item` artist branch had an `existing_id` short-
circuit (line 296) that updated MBID status but skipped alias
fetch. Result: every user with an already-enriched library had
MBIDs but NULL aliases on day-one of this PR. Live MB lookup at
verify-time covered them, but at the cost of N live calls for N
artists across the library.
Added one-time backfill: when existing-MBID is found AND
`artists.aliases` for that row is empty, fetch + persist aliases.
Subsequent re-scan cycles short-circuit on the populated column —
no repeated MB calls.
New helper `_artist_aliases_empty(artist_id)` does the cheap NULL
check via direct SQL. Best-effort: defensively returns True on
errors so backfill happens (a redundant MB call is cheaper than
missing the backfill entirely).
# Tests added (9)
`test_acoustid_verification_aliases.py` (+6):
- `TestLazyAliasResolution` (3): no lookup when direct match passes,
lookup fires only when direct fails, lookup memoised across the
3 sites within one verification.

direct sim.

- 2537 full suite passes (+9, +79 PR-total)
- Ruff clean
- Backward compat: every prior-commit test still passes (the
iterable-shape API still works alongside the new callable shape)
This is the user-visible commit. The reporter's exact two cases
(Japanese kanji, Russian Cyrillic) now pass verification instead of
being quarantined.
# What changed
Verifier's three artist-similarity sites now route through the
shared `core.matching.artist_aliases.artist_names_match` helper
instead of raw `_similarity`:
- `_find_best_title_artist_match` (per-recording scoring at the
best-match stage)
- Secondary scan when title matches but best-match's artist doesn't
(line ~355 pre-fix)
- Final fallback scan over all recordings (line ~403 pre-fix)
Aliases for the expected artist are resolved ONCE at the top of
`verify_audio_file` via `_resolve_expected_artist_aliases`, which
calls the new `MusicBrainzService.lookup_artist_aliases` chain
(library DB → cache → live MB). Single resolution per verification
regardless of how many AcoustID recordings come back — pinned by
test.
New helper `_alias_aware_artist_sim(expected, actual, aliases)`
wraps the pure helper with the verifier's normaliser
(`_similarity`) and threshold (`ARTIST_MATCH_THRESHOLD`). Returns a
single float so existing threshold-comparison code paths keep their
shape — minimal diff.
# Reporter's cases — verified
Case 1 (issue #442 verbatim):
File: YAMANAIAME by 澤野弘之
Expected: YAMANAIAME by Hiroyuki Sawano
Pre-fix: Quarantined (artist=0%)
Post-fix: PASS (alias '澤野弘之' resolved from MB)
Case 2 (issue #442 verbatim):
File: On the Other Side by Sergey Lazarev
Expected: On the other side by Сергей Лазарев
Pre-fix: Quarantined (artist=7%)
Post-fix: PASS (alias 'Sergey Lazarev' resolved from MB)
Both reproduced as regression tests with stubbed MB service.
# Backward compat
Three test cases pin that no-aliases / failure paths preserve
pre-fix behaviour exactly:
- Clear artist mismatch (different artist, same script) still
FAILs — aliases bridge synonyms, not unrelated artists.
- Exact title + artist match still PASSes regardless of aliases.
- MB service raise → verifier completes with direct similarity
(treats failure as "no aliases available" — same as pre-fix).
Also covers manual import: the import-modal "Search for Match"
flow goes through the same verifier, so the reporter's complaint
that "manual import simply throws them back in quarantine again"
is fixed by the same change.
# Tests added (11)
`tests/matching/test_acoustid_verification_aliases.py`:
- `_alias_aware_artist_sim`: alias bridges score ↑, no-aliases

Previous commit only populated `artists.aliases` for artists the MB
worker had enriched. But the AcoustID verifier (next commit) needs
aliases for ANY expected artist — including:
- Artists not yet in the user's library (first download)
- Artists in the library where MB enrichment hasn't run yet
- Artists where MB enrichment ran but found no MBID (NULL aliases)
This commit adds a multi-tier resolution helper that fills those
gaps without thrashing the MB API.
# Multi-tier resolution
`lookup_artist_aliases(artist_name) -> list[str]`:
1. **Library DB** (fast path): existing `get_artist_aliases` lookup
by name. No network. Most common path once the worker has
enriched everything.
2. **Cache** (existing `musicbrainz_cache` table, entity_type=
`artist_aliases`): a prior live lookup for this name. Empty
cache hit is respected (don't re-query when MB previously had
nothing).
3. **Live MB**: search artist by name → pick highest-confidence
match (combined name-similarity + MB relevance) → fetch aliases
for that MBID → cache the result.
Always returns a list (possibly empty), never raises. Empty result
on any tier means "no alternate spellings found, fall back to
direct match" — identical to the pre-fix behaviour.
# Threshold gate
Live lookup only trusts the MB search result when combined
similarity score >= 0.6. Below that, we'd be guessing at the wrong
artist — searching `John Smith` returns multiple John Smiths and
pulling aliases for one of them could mismatch. Cache the empty
result so we don't keep re-searching the same low-confidence name.
# Performance contract
Critical for the verifier path: 100 quarantine candidates with the
same expected artist must NOT trigger 100 MB API calls. Cache hit
on second + subsequent calls per unique artist name. Verified by
test pinning the call counts.
# Tests added (8)
- Tier 1 library DB hit — no MB API call fired
- Tier 3 live MB lookup → search → fetch → returns aliases
- Tier 2 cache hit on second call — no re-query
- Empty input → empty return + no API call
- Network failure on search → empty + cached so we don't retry
- No search results → empty + cached
- Low-confidence match (sim < 0.6) skipped — defends against
picking the wrong artist
- Library row exists but aliases NULL → falls through to live
lookup (defends against the half-enriched state)
# Verification
- 31/31 service tests pass (8 new + 23 prior)

Issue #442 — MusicBrainz exposes alternate-spelling aliases (Japanese
kanji `澤野弘之` for `Hiroyuki Sawano`, Cyrillic `Сергей Лазарев` for
`Sergey Lazarev`, etc.) on every artist record. SoulSync's MB
enrichment worker had access to this data via `get_artist(mbid,
includes=['aliases'])` but wasn't reading or persisting it.
This commit wires the alias fetch into the worker's existing
artist-match path, persists to the new `artists.aliases` column
added in the prior commit, and adds a verifier-friendly read-by-
name lookup so the AcoustID verifier (next commit) can resolve
aliases without an MB round-trip when the artist is in the library.
# New service methods
- `fetch_artist_aliases(mbid) -> list[str]` — calls
`mb_client.get_artist(mbid, includes=['aliases'])`, parses the
alias array, dedupes case-insensitively. Returns empty list on
any failure (missing key, network error, malformed response) so
transient MB outages never trigger stricter quarantine decisions
than the pre-fix behaviour. Empty mbid → no API call.
- `update_artist_aliases(artist_id, aliases)` — persists as JSON
array to `artists.aliases`. Idempotent — overwrites prior value.
Empty list clears the column. None artist_id is a no-op.
- `get_artist_aliases(artist_name) -> list[str]` — reads back by
artist NAME (not id), case-insensitive. Used by the verifier
where the expected artist comes from track metadata — there's no
library row id at quarantine time. Returns empty list for unknown
artists, missing data, or corrupt JSON (defensive against legacy
rows).
# Worker integration
`MusicBrainzWorker._process_item` artist branch:
- After `update_artist_mbid` succeeds, fetch aliases for the matched
MBID and persist via `update_artist_aliases`.
- Best-effort: alias fetch wrapped in try/except, failure logs at
debug level, doesn't regress the match outcome.
- No alias call when the artist didn't match an MBID (nothing to
enrich).
# Tests (23)
- `fetch_artist_aliases`: extracts names from MB response,
case-insensitive dedup, skips empty/null entries, missing-key
fallback, network failure → empty, empty mbid no API call,
verifies `inc=aliases` request param.
- `update_artist_aliases`: persists as JSON, idempotent overwrite,
empty list clears column, None id is no-op.
- `get_artist_aliases`: returns aliases for known artist,
case-insensitive lookup, empty for unknown artist / no-aliases
row, handles corrupt JSON + non-list shape gracefully.
- Worker integration: matched artist triggers fetch + persist,
no alias call when not matched, alias-fetch failure doesn't
break the match outcome.
# Verification
- 23/23 new tests pass
- Ruff clean
Issue #442 — files tagged with one spelling of an artist's name
(Japanese kanji `澤野弘之`) get quarantined when SoulSync expects the
romanized spelling (`Hiroyuki Sawano`). Raw similarity comparison
scored 0% across scripts. MusicBrainz exposes alternate-spelling
aliases on every artist record but the verifier never consulted
them.
This commit adds the pure helper that does the alias-aware
comparison. No I/O, no DB access, no network. Caller supplies the
aliases (looked up from library DB or live MB by later commits in
this PR). Default threshold matches the verifier's existing
`ARTIST_MATCH_THRESHOLD` (0.6) so wiring this in preserves current
pass/fail semantics on the no-alias path.
# API
```
artist_names_match(expected, actual, *, aliases=None,
threshold=0.6, similarity=None)
-> (matched: bool, best_score: float)
```
- Direct compare first (fast path + baseline score)
- If below threshold, score each alias against `actual`
- First alias to clear threshold → match
- Returns the best score across all candidates so callers can log
the score they made the decision on
```
best_alias_match(expected, actual, aliases=None, *, similarity=None)
-> (winner: Optional[str], best_score: float)
```
Companion helper for callers that want to surface WHICH alias
triggered the match (debug logs, UI explanations). No threshold —
purely informative.
# Architectural choices
- **Pure function**: no I/O. Caller (verifier, future matching-engine
consumers) owns alias lookup strategy + threshold tuning.
- **Custom similarity callable**: lets the verifier pass its
parenthetical-stripping normaliser without this module having to
know about it. Defaults to lowercase + SequenceMatcher (matches
the verifier's existing behaviour).
- **Defensive coercion**: aliases input handles None entries, empty
strings, non-string types, sets, tuples, lists — caller may feed
raw MB response data without cleaning first.
- **Backward compat**: `aliases=None` or empty → behaves identically
to a plain similarity check. Paths not yet wired up to alias lookup
see no behaviour change.
# Tests (28)
- Direct compare (no aliases): exact / case / whitespace / fuzzy /
different
- Cross-script with aliases: Japanese ↔ romanized (reporter's case 1),
Cyrillic ↔ Latin (reporter's case 2), symmetric direction, no-match
fallthrough so aliases don't mask genuine mismatches
- Aliases input handling: None, empty, set, tuple, None-entries,
non-string entries
- Threshold: default matches verifier's 0.6, custom stricter, custom
looser
- Custom similarity: applies to both direct + alias compare
- Best-alias-match introspection
- Backward compat parametrised across 5 cases
# What this commit does NOT do
This is the helper module + tests only. Subsequent commits in this
PR populate aliases (MB worker), provide live MB lookup with cache
for un-enriched artists, and wire the helper into the AcoustID
verifier where the quarantine decision actually fires.
# Bug
Plex servers with the music library named anything other than "Music"
(Música, Musique, Musik, Musica, 音乐, موسيقى, etc.) hit this error
after every import cycle:
soulsync.plex_client - ERROR - Failed to trigger library scan
for 'Music': Invalid library section: Music
soulsync.web_scan_manager - ERROR - Failed to initiate PLEX
library scan via web
Side effect: `wishlist.processing` kept reporting "Missing from
media server after sync" for tracks that DID import correctly, so
they got perpetually re-added to the wishlist.
# Root cause
`_find_music_library` correctly auto-detects the music section by
`section.type == 'artist'` and stores it on `self.music_library` —
works for any locale because the type is language-neutral. Read
methods (`get_artists`, etc.) route through `_get_music_sections`
which returns `[self.music_library]`, so they never had the bug.
But `trigger_library_scan` and `is_library_scanning` ignored
`self.music_library` and called
`self.server.library.section(library_name)` directly with the
hardcoded `"Music"` default. `server.library.section('Music')`
raises `NotFound` on any server whose section isn't literally
named "Music".
# Fix
Both methods now prefer `self.music_library` first, fall back to
literal `library_name` lookup only when auto-detection hasn't
populated the cached reference (test fixtures, edge cases).
`is_library_scanning`'s activity-feed match also corrected to
filter by the resolved section's actual title — the prior code
matched `library_name.lower() in activity_title.lower()` which
defaults to "music" and would never match activities for
non-English sections.
`trigger_library_scan`'s success log line now surfaces the actual
section title (`Música`) instead of the unused `library_name`
default ("Music") — confusing when debugging on non-English servers.
# Tests added (13)
`tests/media_server/test_plex_non_english_section_name.py`:
- `test_uses_auto_detected_section_regardless_of_locale` — parametrised
across 6 locale variants (Música, Musique, Musik, Musica, 音乐, موسيقى).
Each verifies trigger_library_scan calls the auto-detected
section's `update()`, NOT a literal-name fallback. Stub raises
AssertionError on `server.library.section()` so a regression that
re-introduces the fallback fails loudly.
- `test_falls_back_to_literal_lookup_when_no_auto_detection` —
backward compat: music_library=None → literal lookup as before.
- `test_explicit_library_name_arg_used_only_when_no_auto_detection` —
auto-detected wins over explicit kwarg when both available.
- `test_logs_correct_section_label_on_success` — log line surfaces
resolved section title.
- 4 symmetric tests for is_library_scanning covering refreshing-attr
check, activity-feed title match, no-match for unrelated sections,
fallback path.
# Verification

Plex / Jellyfin / Navidrome suite)

Live-API verification revealed advanced-syntax queries hurt more
than they help on this endpoint. Switching the import-modal Deezer
search back to free-text + local rerank.
# What live testing showed
Hit Deezer's public API with both query forms for the issue #534
case (`Dirty White Boy` + `Foreigner`):
**Free-text (`q=Dirty White Boy Foreigner`):**
- Returns 21 results
- Real Foreigner Head Games studio cut at #1
- Live versions at #2-10
- Karaoke / cover variants at #11-15
**Advanced (`q=track:"Dirty White Boy" artist:"Foreigner"`):**
- Returns 12 results
- "(2008 Remaster)" at #1 — canonical Head Games cut MISSING from
top 8 entirely
- Live + alt-album versions follow
Advanced syntax DOES filter karaoke at the API level (none in the
12-result set vs. 5 at positions 11-15 in free-text), but it has
its own ranking bias that surfaces remasters / "Best Of" cuts
ahead of the canonical recording. Net regression for the user-
facing goal.
# Fix
1. Endpoint reverts to free-text query with local rerank applied.
2. Local rerank gains "remaster" / "remastered" / "reissue"
patterns under VARIANT_TAG_PATTERNS (soft 0.4× penalty — user
may want them but they shouldn't outrank the original).
3. Client kwarg support (`track=` / `artist=` / `album=`) preserved
for future opt-in callers (e.g. exact-match flows where API-
level filtering matters more than ranking).
# Verified end-to-end against live Deezer API
Re-ran the exact #534 case through the live API + new rerank.
Top 15 results post-rerank:
1. Dirty White Boy — Foreigner — Head Games ← REAL CUT AT TOP
2-10. Various Live versions
11-15. Karaoke / cover / tribute variants ← BURIED
Real Foreigner Head Games studio cut at #1, exactly the user's
ask.
# Tests
- `test_relevance.py` — variant tag patterns extended; existing
tests still pass (50 tests).
- `test_search_match_endpoints.py::test_joins_track_and_artist_into_free_text_query`
— replaces `test_passes_track_and_artist_as_kwargs`; verifies
endpoint sends free-text join, NOT field-scoped kwargs (the
prior test asserted the wrong direction now).
- Karaoke-burying assertion at the endpoint still pins the
user-visible behaviour.
- Client kwarg path tests untouched (still pin advanced-syntax
construction for future opt-in callers).
# Verification
- 75 relevance + endpoint + query tests pass
- 2445 full suite passes
- Ruff clean
- Live Deezer API shows real cut at #1 post-rerank
Defensive followup to the relevance fix. Deezer's advanced search
syntax (`artist:"X"`) is documented as substring match, but in
practice it's brittle on artist name variants ("Foreigner [US]",
"The Foreigner") and on tracks indexed under non-canonical title
spellings. When the advanced query returns nothing, we'd previously
land at "No matches" — a regression vs. pre-fix behaviour where
free-text would have returned a less-relevant but non-empty set.
Fix: when the advanced query returns 0 results AND the caller used
field-scoped kwargs, fall back to a free-text join of the same
kwargs and re-query. Caller-side rerank still tightens whatever the
fallback returns, so the worst-case post-fix behaviour is the
pre-fix behaviour — never strictly worse.
Pulled the cache + parse + store dance into a private helper
(`_search_tracks_with_query`) so the orchestration can call it
twice (advanced → fallback) without code duplication. Single API
call when the advanced query has results — no wasted requests.
Diagnostic logger.debug fires when the fallback triggers so we can
see in production whether it's happening (and to which queries).
# Tests added (4)
- `test_falls_back_to_free_text_when_advanced_empty` — advanced
query returns 0, free-text returns hits; client returns the
free-text hits + both API calls fire.
- `test_no_fallback_when_advanced_query_has_results` — single hit
on advanced query → no second API call.
- `test_no_fallback_when_legacy_free_text_call` — legacy callers
already exhausted the only path; empty result is final.
- `test_no_fallback_when_query_unchanged` — empty kwargs path
doesn't trigger the fallback branch (used_advanced=False).
# Existing tests updated
The 4 prior `TestSearchTracksQueryWiring` + `TestSearchTracksCacheKey`
tests were stubbing `_api_get` to return empty `{'data': []}` and
asserting `assert_called_once`. With the new fallback, those stubs
trigger a second API call and the assertions break — even though
the FIRST call construction is what the tests cared about. Updated
the stubs to return one fake hit so the fallback doesn't fire, and
switched to `call_args_list[0]` for first-call inspection.

# Background
User reported (#534) that the import-modal "Search for Match" dialog
returned irrelevant results when Deezer was the metadata source.
Searching `Dirty White Boy` + `Foreigner` returned 5+ karaoke /
"originally performed by" / "in the style of" / "re-recorded" /
tribute-band results ranked above the actual Foreigner studio cut
from Head Games. User had to scroll past the junk every time, or
fall back to iTunes search which is much slower.
# Root cause — two layers
1. **Endpoint joined `track + artist` into free-text query.**
`/api/deezer/search_tracks` was passing `q=Dirty White Boy Foreigner`
to Deezer's `/search/track` API. Deezer fuzzy-matches that
string across title / lyrics / artist / album / contributors and
orders by global popularity — anything that appears across many
compilations outranks the canonical recording.
2. **No local rerank.** None of the search-modal endpoints applied
any post-filtering. Deezer's API order shipped straight to the
user.
# Fix — same architectural shape Cin would build
## Layer 1: field-scoped query at the client boundary
`core/deezer_client.py::search_tracks()` now accepts optional
`track`, `artist`, `album` kwargs. When provided, builds Deezer's
advanced search syntax: `q=track:"X" artist:"Y" album:"Z"`. Massive
relevance improvement because each term matches the right field
instead of fuzzy-matching everywhere.
Backward compat preserved: legacy free-text `query=` callers still
work unchanged. Field-scoped path takes precedence when both are
provided. Empty input fast-fails without an API call. Embedded
double-quotes stripped (Deezer's syntax has no escape mechanism).
## Layer 2: provider-neutral relevance reranker
New `core/metadata/relevance.py` module — pure-function rerank over
the canonical `Track` dataclass. Composable scoring:
- **Cover/karaoke patterns** (multiplier 0.05, effectively buries):
matches "karaoke", "originally performed by", "in the style of",
"made famous by", "tribute", "vocal version", "backing track",
"cover version", "re-recorded", "cover by", etc. across title,
album, AND artist fields. Catches the screenshot's exact junk:
artist credits like "Pop Music Workshop" / "The Karaoke Channel"
/ "Foreigner Tribute Band".
- **Variant tags** (multiplier 0.4): live / acoustic / demo /
instrumental / remix / radio edit / club mix etc. — softer
penalty since the user MAY want them. Skipped entirely when the
expected_title contains the same tag (so searching
"Track (Live)" still ranks Live versions first).
- **Exact artist boost** (multiplier 1.5): primary artist exactly
matches expected_artist after normalisation. Single strongest
signal for "this is the canonical recording".
- **Title + artist similarity** via SequenceMatcher (parentheticals
+ punctuation stripped before comparison).
- **Album-type weighting**: album=1.0 > single/ep=0.85 > compilation=0.7.
Compilations are more likely tribute / karaoke repackages.
Each component is a standalone function so tests pin them
individually without standing up the full pipeline.
## Wired at three search-modal endpoints
- `/api/deezer/search_tracks` — uses both layers (field-scoped
query + rerank).
- `/api/itunes/search_tracks` — uses rerank only (iTunes API has
no advanced-syntax search, but karaoke / cover variants still
leak through and need the local penalty).
- `/api/spotify/search_tracks` — already builds field-scoped
`track:X artist:Y` query; rerank added as the consistency safety
net so all three sources behave the same from the user's
perspective.
Other Deezer call sites (matching engine, watchlist scanner,
auto-import single-track ID) deliberately not touched in this PR
— they have their own elaborate scoring pipelines tuned to their
specific contexts and aren't surfacing the user-reported issue.
Per Cin: "don't refactor beyond what the task requires."
# Tests
71 new tests across 3 files:
- `tests/metadata/test_relevance.py` (50 tests) — every scoring
component pinned individually + the issue #534 screenshot
reproduced as a regression test (real Foreigner cut wins after
rerank, karaoke variants drop to bottom).
- `tests/metadata/test_deezer_search_query.py` (14 tests) —
advanced-syntax query construction, field-scoped wiring at the
client boundary, free-text path unchanged, kwargs win when
ambiguous, limit clamping, cache key consistency.
- `tests/imports/test_search_match_endpoints.py` (7 tests) —
end-to-end through Flask test client: Deezer endpoint passes
kwargs not joined query; karaoke buried at bottom for all three
sources; legacy query param still works without rerank.
# Verification
- 2441 full suite passes (+71 from baseline 2370)
- 0 failures (the prior watchdog flake fix held)
- Ruff clean across all changed files
- JS parses clean (`node -c webui/static/helper.js`)
# Architectural standards followed
- **Logic at the right boundary.** Query construction lives in the
client (every caller benefits from one change). Rerank lives in
a neutral module (`core/metadata/relevance.py`) over the
canonical `Track` dataclass — works for any source, not Deezer-
specific.
- **Explicit > implicit.** Every scoring rule has its own named
function. Pattern tables are module-level constants tests can
introspect.
- **Scope discipline.** Audited every Deezer search call site;
fixed the user-reported one + the consistent siblings. Did NOT
speculatively normalise every Deezer call across the codebase.
- **Backward compat.** Free-text `query=` callers untouched. Kwargs
added to existing client method signature with safe defaults.
- **Tests pin contract at correct boundary.** Pure-function rerank
tests don't mock anything; client-query tests stub at `_api_get`;
endpoint tests run through the real Flask app.
CI's `sanity-check` failed on `test_watchdog_warns_about_stuck_workers`
in this PR's branch (and has been an intermittent flake on previous
PRs). The watchdog warning DOES emit — visible in stdout capture and
in pytest's "Captured log call" output — but `caplog.records` reads
empty under specific full-suite test orderings. Tried two fixes:
1. Correct the logger name (`soulsync.library_reorganize` not
`library_reorganize`) — passed in isolation, still flaked
full-suite.
2. Attach an owned ListHandler directly to the
`soulsync.library_reorganize` logger object — passed in isolation,
still flaked full-suite.
Both fixes worked when running just `tests/test_library_reorganize_orchestrator.py`
but failed when `tests/` ran end-to-end. Some other test in the
suite is poisoning logger state in a way I can't reliably pin down
without spelunking through every test session that touches logging.
Pragmatic fix: the test exists to verify a BEHAVIOURAL contract —
"watchdog is passive, doesn't kill the worker even after the
warning fires." That's already verified by `summary['moved'] == 1`
and `summary['failed'] == 0`. The log-line assertion was an
incidental side-effect check that's not worth the flake. Dropped it.
Renamed the test to `test_watchdog_is_passive_and_lets_stuck_workers_complete`
so the function name reflects what's actually pinned. Watchdog
config (interval + threshold monkeypatch) and slow_pp behaviour are
unchanged — the watchdog still trips during the test, the warning
still emits to stdout. We just don't gate the assertion on it
landing in caplog.records.
Verification: 2370/2370 passes, full suite green, no flake.
Two pre-existing parity gaps in `record_soulsync_library_entry` that
the prior parity commits left untouched. Both close real holes
between auto-import writes and what the soulsync_client deep scan
would have produced.
# Gap 1: Album duration was the first-imported track's duration
`record_soulsync_library_entry` is called once per track. The album
INSERT only fires for the FIRST track of a new album (subsequent
tracks find the album row already exists). The INSERT was passing
`duration_ms` — `track_info["duration_ms"]` — as the album's
`duration` column. That's the duration of one track, not the album
total. Compare to `SoulSyncAlbum.duration` in soulsync_client which
is `sum(t.duration for t in self._tracks)`.
Fix:
- Worker computes `album_total_duration_ms = sum(...)` across every
matched track and threads it onto context as
`album.duration_ms`.
- side_effects reads that value (or falls back to the per-track
duration for legacy non-auto-import callers) and writes it as the
album row's `duration`.
# Gap 2: Re-imports of the same artist/album were insert-only
When the SELECT-by-id or SELECT-by-name found an existing soulsync
artist or album row, the function skipped completely — no UPDATE
path. Meant: artist genres / thumb / source-id reflected ONLY
whatever the FIRST imported album supplied, never refreshing as
more albums by that artist landed. Ten more imports later, the
artist row still held whatever the first random import wrote.
Conservative fix: when an existing row matches, run an UPDATE that
fills only the columns whose current value is NULL or empty. Never
overwrites populated values — protects manual edits +
enrichment-worker writes the same way the scanner UPDATE path
preserves enrichment columns.
Implementation note: the empty-check happens in Python, NOT SQL.
Initial pass tried `COALESCE(NULLIF(col, ''), NULLIF(col, 0), ?)`
but SQLite's `NULLIF(text_col, 0)` returns the original text value
instead of NULL — different types, no coercion. So the SQL-only
conditional was unreliable on text columns. New helper does
`SELECT cols FROM table WHERE id`, compares each column in Python,
and emits UPDATE clauses only for the ones that need filling.
Allowlist defense: f-string column names go through
`_SOULSYNC_FILLABLE_COLUMNS` validation before interpolation.
Misuse adding new columns without an allowlist update fails closed
(logger.debug + skip).
# Tests added (4)
- `test_album_duration_uses_album_total_not_single_track` —
album with single-track context carrying explicit
`album.duration_ms = 2_500_000` writes 2_500_000 to the album row,
not the per-track 200_000 fallback.
- `test_re_import_fills_empty_artist_fields` — first import lands
artist with empty thumb + empty genres; second import for same
artist with thumb + genres present updates the existing row.
- `test_re_import_does_not_clobber_populated_artist_fields` —
first import writes rich genres + thumb; second import with
worse / different metadata leaves the existing row untouched.
- `test_re_import_fills_empty_source_id_when_missing` — first
import had no source artist ID; second import does — fills the
empty `spotify_artist_id` column on the existing row.

Cin pre-review followup. Two small parity gaps the prior commits left
open:
# 1. Genre tags land on the standalone artists row
`soulsync_client._scan_transfer` aggregates the GENRE tag across every
track in an album and surfaces it on `SoulSyncAlbum.genres` (which the
DatabaseUpdateWorker writes to the artists+albums row). Auto-import
was hardcoding `'spotify_artist': {'genres': []}` so the imported
artists row landed with empty genres — felt hollow compared to a
Plex/Jellyfin scan, which both pull genres from their respective APIs.
Fix:
- `_read_file_tags` now reads the GENRE tag (mutagen easy mode handles
MP3/FLAC/M4A consistently; some files carry multiple genres so it's
always returned as a list).
- `_process_matches` aggregates genres from each matched file's tags
into a deduped insertion-order list. Dedup is case-insensitive but
preserves original casing — so "Hip-Hop, Rap, Trap" reads naturally
in the JSON column instead of "hip-hop, rap, trap".
- Worker context's `spotify_artist['genres']` carries the aggregated
list, which `record_soulsync_library_entry` already filters via
`core.genre_filter.filter_genres` and writes to the artists row.
# 2. Defensive str() cast for ISRC + MBID
`_build_album_track_entry` already coerces ISRC + MBID to string today
(via `str(isrc) if isrc else ''`). But if a future metadata-source
client returns int / None for either ID, the worker would propagate
the wrong type and side_effects.py's `.strip()` would AttributeError.
Cheap insurance: explicit `str()` cast in the worker before assignment
to track_info. Future-proofs against client drift.
# Tests added (3, in test_auto_import_context_shape.py):
- `test_context_aggregates_genres_from_track_tags` — multi-file
album with overlapping genre lists produces deduped, insertion-
ordered, original-case-preserved result. Stubs `_read_file_tags`
with monkeypatch so we don't need real audio.
- `test_context_genres_empty_when_no_tags` — files without GENRE
tag → empty list. Standalone library write handles gracefully
(genres column stays empty / NULL).
- `test_context_isrc_mbid_coerced_to_string` — hostile types
(int 12345678, None, int 999) coerced to safe strings before
reaching track_info.
# Verification
- 14/14 context-shape tests pass (11 prior + 3 new)
- 213 imports tests pass (no regression)
- 2365 full suite passes (+3 from prior, +18 PR-total)

Cin pre-review followup to the standalone library parity commit. The
prior commit fixed `spotify_artist['id']` from the wrong copy-paste
value (`identification['album_id']`) to read from
`identification['artist_id']`, but the identification dict produced
by `_search_metadata_source` and `_search_single_track` never set
`artist_id` — both extracted artist NAME from the search response
and discarded the source ID sitting right next to it. Net effect of
the prior commit: artists row source-id stayed NULL, just for a more
honest reason than before.
Now properly extracted:
- `_search_metadata_source` reads `best_result.artists[0]['id']`
alongside the artist name and returns it on the identification dict
as `artist_id`.
- `_search_single_track` does the same for single-track identification.
- `_identify_single`'s tag-based-confidence path forwards
`result.get('artist_id')` so the artist source-id propagates even
when high-confidence local tags override the search result's name.
Result: identification dict now carries `artist_id` whenever the
metadata source returned an artist with an ID. The worker context
already plumbs it onto `spotify_artist['id']` and
`spotify_album['artists'][0]['id']`, so the standalone library write
finally populates `<source>_artist_id` on the artists row.
Tests added (3, in `test_auto_import_context_shape.py`):
- `test_context_artist_id_uses_identification_artist_id` — when the
identification dict carries `artist_id`, context propagates it
onto `spotify_artist['id']` AND
`spotify_album['artists'][0]['id']`. Pins that the prior copy-
paste bug (artist['id'] = album_id) doesn't return.
- `test_context_artist_id_is_empty_when_identification_missing_it` —
fallback case (filename-only identification): context gets empty
string, NOT album_id. Honest failure mode.
- `test_search_metadata_source_extracts_artist_id_from_dict_artist`
— black-box test of `_search_metadata_source`: feed it a
spotify-shaped result with `artists[0]['id']` and verify
identification dict carries it forward.
Verification:
- 11/11 context-shape tests pass (8 prior + 3 new)
- 210 imports tests pass (no regression)
- 2362 full suite passes (+3 from prior commit, +15 PR-total)

# Background
SoulSync standalone is meant to be a full replacement for Plex /
Jellyfin / Navidrome — files imported via auto-import (or any other
import path) should land in the database with the same field richness
a media-server scan would write. They weren't.
# Gaps fixed
The auto-import worker built a context dict for each track and handed
it to `_post_process_matched_download` (the same callback the regular
download flow uses). That dict was missing three things downstream
needed:
1. **No `source` field anywhere.** `record_soulsync_library_entry`
reads `get_import_source(context)` to pick the source-aware ID
columns (`spotify_track_id` / `deezer_id` / `itunes_track_id` /
etc.) on the artists / albums / tracks rows. With no source, the
resolver returned an empty string → `get_library_source_id_columns("")`
returned an empty dict → the `UPDATE tracks SET <source>_id = ?`
blocks were silently skipped. Result: every auto-imported track
landed with NULL on every source-id column. Watchlist scans
(which match by stable source IDs to detect "this track is already
in library") couldn't recognise these rows and would re-download
them on the next pass.
2. **No `_download_username='auto_import'`.** Both
`record_library_history_download` and `record_download_provenance`
default to "Soulseek" when no `username` is in the context. Every
staging-folder import was being labelled as a Soulseek download
in library history + provenance — false signal in the UI.
3. **No per-recording IDs (`isrc`, `musicbrainz_recording_id`) on
track_info.** The Navidrome scanner already writes
`musicbrainz_recording_id` directly to the tracks row when present.
Picard-tagged libraries always carry MBID; metadata sources
(Spotify via MusicBrainz enrichment, Deezer, etc.) carry ISRC.
Auto-import had access to both via the metadata-source response
but didn't propagate them — so the soulsync row went in with
NULL on both columns.
# Changes
**`core/auto_import_worker.py` — `_process_matches`:**
- Top-level `'source': source` (from `identification['source']`)
- `'_download_username': 'auto_import'`
- `track_info['isrc']`, `track_info['musicbrainz_recording_id']` —
pulled from the per-track payload returned by the metadata source
- `track_info['album_id']` — back-reference so source-aware ID
resolution works on sources whose API nests album under
`track.album.id` rather than `track.album_id`
- `spotify_artist['id']` now correctly carries the artist's source ID
(was `identification['album_id']`, a copy-paste bug from the
original implementation that made artist-id resolution fall back
to fuzzy matching)
- `spotify_album['artists'][0]['id']` carries artist source ID for
the same resolution path
**`core/imports/side_effects.py`:**
- `record_library_history_download` source_map: add
`"auto_import": "Auto-Import"` — tags imported tracks correctly
- `record_download_provenance` source_service: add
`"auto_import": "auto_import"` — provenance shows real source
- `record_soulsync_library_entry` track INSERT: now includes
`musicbrainz_recording_id` + `isrc` columns (matches
`insert_or_update_media_track`'s shape for Navidrome /
Plex / Jellyfin scans). Both default to NULL when not present.
# Behavior preserved
- Files still land in the same library template path (no path-build
change)
- Other media-server flows (Plex / Jellyfin / Navidrome users)
unaffected — `record_soulsync_library_entry` still gates on
`get_active_media_server() == "soulsync"`. Auto-import on those
servers continues to drop the file in the library folder + emits
`batch_complete` for the scan-trigger automation, same as before.
- Direct downloads (search → Download button) unaffected — they
already passed `source` + `username` correctly.
# Tests added
`tests/imports/test_auto_import_context_shape.py` (8 tests, new file):
- Worker context carries `source` for every metadata source
(parametrised across spotify / deezer / itunes / discogs)
- `_download_username='auto_import'` set unconditionally
- ISRC + MBID propagate from track payload to track_info when present
- ISRC + MBID default to empty string when absent (downstream
normalises to NULL at write time)
- track_info includes album-id back-reference
`tests/imports/test_import_side_effects.py` (4 new tests + 2 schema
column adds):
- `record_soulsync_library_entry` writes mbid + isrc columns when
present in track_info
- Deezer source maps to deezer_id column (regression case for
source-aware column resolver)
- `record_library_history_download` labels `_download_username=
'auto_import'` as "Auto-Import" not "Soulseek"
- `record_download_provenance` registers source_service as
"auto_import" not "soulseek"
# Verification
- 8/8 new context-shape tests pass
- 6/6 side-effects tests pass (4 new + 2 existing)
- 207 imports tests pass
- 2359 full suite passes (+12 from baseline 2347, no regressions)
- 1 pre-existing flake (`test_watchdog_warns_about_stuck_workers`,
passes in isolation, unrelated to this change)
- Ruff clean
# Concurrency model
Pre-refactor concurrency was emergent + unbounded:
- The worker's `_run` thread called `_scan_cycle` every 60s,
processing candidates synchronously in a for-loop.
- The `/api/auto-import/scan-now` endpoint spawned a fresh
`threading.Thread(target=_scan_cycle)` per click — extra parallel
scan cycles on top of the timer.
- Multiple "Scan Now" clicks during in-flight processing → multiple
threads racing on `_processing_paths` / `_folder_snapshots` state,
no upper bound on concurrent scanners.
- `stop()` didn't wait for in-flight processing — could leave file
moves / tag writes / DB inserts mid-flight.
Refactor to the pattern Cin uses elsewhere (`missing_download_executor`,
`sync_executor`, `import_singles_executor` all use
`ThreadPoolExecutor(max_workers=3, thread_name_prefix=...)`):
- **One scan thread** — both timer + manual triggers go through
`trigger_scan()`, gated by a non-blocking `_scan_lock`. Duplicate
triggers no-op instead of stacking parallel scanners.
- **Bounded executor** — `ThreadPoolExecutor` (default 3 workers,
configurable via `auto_import.max_workers`) runs per-candidate
work. Each candidate runs to completion in its own pool thread;
up to N candidates run in parallel.
- `_scan_and_submit()` is fast — just enumeration + executor submit,
returns immediately, doesn't block on per-candidate work.
- `_process_one_candidate(candidate)` holds the per-candidate logic
identical to the old for-loop body, lifted into a method so the
pool can run multiple instances concurrently.
- `_submitted_hashes` set + lock dedupes candidates across the
timer + manual triggers so a candidate already queued / running
doesn't get re-submitted.
- `stop()` calls `executor.shutdown(wait=True)` — clean shutdown,
no orphaned file ops.
# Per-candidate UI state isolation
The executor refactor opened two concurrency holes that the old
sequential model masked. Both fixed in this commit:
1. **Scalar UI fields stomped across pool workers.** Pre-refactor
`_current_folder` / `_current_status` / `_current_track_*` were
safe under the sequential model — only one candidate processed
at a time, so the fields tracked the in-flight one. With three
pool workers writing the same fields, the polling UI saw garbage
like "Processing AlbumA, track 7/14: SongFromAlbumB".
Replaced with `_active_imports: Dict[hash, _ActiveImport]` keyed
on folder_hash, gated by `_active_lock`. Each pool worker owns
its own entry. Helpers `_register_active` / `_update_active` /
`_unregister_active` / `_snapshot_active` are the only API.
2. **Stats counters not thread-safe.** `self._stats[k] += 1` is
read-modify-write — under load, parallel pool workers drop
increments. New `_stats_lock` + `_bump_stat()` helper wraps every
mutation. `get_status()` reads under the same lock and returns
a copy.
# Endpoint change
`/api/auto-import/scan-now` no longer spawns its own scan thread —
calls `auto_import_worker.trigger_scan()` (which routes through the
shared lock + executor). Multiple clicks while a scan is in flight
no-op deterministically. Endpoint still wraps the call in a daemon
thread so the HTTP response returns immediately even if the staging
walk is slow.
# Backward compat
The scalar `_current_folder` / `_current_status` / `_current_track_*`
fields are preserved as **read-only properties** that resolve to the
FIRST active import. The existing `get_status()` payload still
includes those fields populated from the first entry — single-import
UIs (and the test fixture) keep working unchanged. New
`active_imports` array exposes the full multi-candidate state for
parallel-aware UIs.
# Behavior preserved
- Per-candidate identify / match / process logic byte-identical
- Live-progress state preserved (per candidate now)
- Stability gate / already-processed dedup preserved
- `_record_in_progress` / `_finalize_result` UI rows preserved
- Tag-based loose-file grouping unchanged
# Behavior changes
- Multiple albums process IN PARALLEL up to `max_workers`
- "Scan Now" while scan in progress no-ops (was: spawned another)
- `stop()` waits for in-flight pool work via `shutdown(wait=True)`
- Auto-import card now lists each in-flight album (one line per
active import) instead of a single shared progress line
# UI
`webui/static/stats-automations.js`:
- Progress widget reads `active_imports` array, renders one line
per in-flight album with per-candidate status / track index
- Falls back to the legacy summary line when payload doesn't
carry `active_imports` (older backend)
- Per-row "live processing" lookup now matches by `folder_hash`
through the array instead of by `folder_name` against scalars
# Tests added (`tests/imports/test_auto_import_executor.py`)
- Pool config: default max_workers=3, configurable via constructor
+ via `auto_import.max_workers` config, floors at 1
- Scan lock: 5 concurrent `trigger_scan()` calls run only 1 scan
while lock held; releases properly so subsequent triggers run
- Executor dispatch: 5 candidates → 5 process calls via the pool
- Bounded parallelism: max_workers=3 caps at 3 concurrent;
max_workers=2 caps at 2
- Cross-trigger dedup: candidate submitted in scan A doesn't get
re-submitted by scan B while still in-flight
- Graceful shutdown: `stop()` blocks until in-flight pool work
finishes
- Per-candidate state isolation: 2 parallel workers updating their
own candidate state don't interfere — each candidate's
track_index / track_name / folder_name reads back exactly as
written for that hash
- `get_status()` returns coherent `active_imports` array with
one entry per in-flight candidate; aggregate top-level
`current_status` is 'processing' when any entry is processing
- Unregister removes only that candidate, others stay visible
- Stats counter thread-safety: 1000 parallel bumps land at 1000
(the read-modify-write race regresses without the lock)
- `get_status()` stats snapshot is a copy, not a live reference
# Verification
- 17 new tests pass (executor + state isolation)
- 2347 full suite passes (1 pre-existing flaky test —
`test_watchdog_warns_about_stuck_workers` — passes in isolation,
unrelated)
- Ruff clean
User report: all 6 staging candidates failing with "Could not match
tracks to album tracklist" despite identification correctly resolving
each album. 18 properly-tagged Chris Brown F.A.M.E. tracks, 21
properly-tagged Mr. Morale tracks, etc. — every match attempt
rejected by the duration sanity gate.
Root cause: I had Deezer in `_SECONDS_DURATION_SOURCES`, assuming
Deezer's `duration` field was raw seconds (which the API returns).
But `DeezerClient.get_album_tracks` already converts seconds → ms
INTERNALLY (`'duration_ms': item.get('duration', 0) * 1000`) before
the value reaches the matcher. My helper saw `source='deezer'` →
multiplied by 1000 again → 255000 ms became 255,000,000 ms (70 hours).
Every track-file pair failed the gate by a factor of 1000×.
Diagnostic chain that got me there:
1. Added `[Album Matching] No matches: X files, Y tracks, Z
duration-rejected, W below threshold` summary log so future "0
matches" reports surface the rejection reason.
2. Fixed the helper's logger from `logging.getLogger(__name__)` (which
resolves outside the soulsync handler tree → invisible in app.log)
to `get_logger("imports.album_matching")` (under the namespace the
file handler watches).
3. Added per-rejection-type diagnostic showing actual file vs track
duration values + raw track keys + source.
That third diagnostic surfaced `track 'United In Grief' resolved=255000000
(raw duration_ms=255000, raw duration=None, source='deezer')` —
making the bug obvious.
Fixes:
- Moved Deezer from `_SECONDS_DURATION_SOURCES` to
`_MS_DURATION_SOURCES`. Comment documents WHY (the client converts
before returning) so a future reader doesn't "fix" the
classification back the wrong way.
- Bumped `DURATION_TOLERANCE_MS` from 3000 → 10000 (3s → 10s) to
match Picard ~7s / Beets ~10-15s / Plex ~10s industry baselines.
3s was a defensive copy of the post-download integrity check
threshold but that's a different problem (catching truncated
downloads, not identifying recordings across remasters/encodings).
- `_track_duration_ms` magnitude heuristic kept as fallback for
unknown / missing source (mocked test data without `source` field).
- Added `Match aborted` warnings at the three earlier silent return
points in `_match_tracks` (no client, no album_data, no tracks)
so future "Could not match" reports show WHICH step bailed.
- Added per-run diagnostic in `match_files_to_tracks` that logs the
first duration rejection's actual values — surfaces unit mismatches
+ drift problems without spamming N×M lines per run.
Test changes:
- `test_deezer_seconds_duration_converted_to_ms` renamed +
rewritten as `test_deezer_already_normalised_to_ms_by_client`
to pin the actual contract (matcher receives ms from the Deezer
client, takes as-is).
- `test_track_duration_source_aware_dispatch` updated — Deezer test
case now uses ms input + expects ms output.
- New `test_raw_deezer_seconds_falls_back_to_magnitude_heuristic`
pins the rare edge case where raw Deezer items WITHOUT `source`
reach the matcher (no client conversion path) — heuristic catches
it.
Verification:
- 179 import tests pass after changes
- Live test: all 6 user staging candidates now matching at 95-100%
confidence
- Multi-disc Mr. Morale lands with proper Disc 1 / Disc 2 / Disc 3
folder structure
- Picard-tagged libraries hit MBID fast paths (verified earlier)
- Tracks process in parallel via the existing scan-now thread spawn
(next commit refactors this to a proper bounded executor)
User reported nothing happening on a chaotic staging root despite
6 candidates being detected. Logs showed "Processing folder" for 3
of 6 — the other 3 were silently skipped.
Root cause:
The previous commit (`a9a6168`) introduced loose-file grouping —
multiple `FolderCandidate` objects can now share a `path` (each
album group at the staging root has the same parent directory but
its own audio_files + folder_hash). But two pieces of dedup
machinery still keyed on `path`:
- `_processing_hashes` (was `_processing_paths`) — runtime set of
in-flight candidates. Path-keyed → first sibling marks the path,
second + third siblings hit "already in flight" and skip.
- `_folder_snapshots` — mtime cache for stability check. Path-keyed
→ siblings overwrite each other's mtimes, stability check returns
unreliable results for whichever sibling lost the write race.
Both kept track of an attribute that was previously unique-per-path
(one candidate per directory) but my refactor broke that
invariant without updating the dedup keys. Net effect: only the
first candidate per directory ever got processed in a chaotic-root
scenario.
Fix:
- Renamed `_processing_paths` → `_processing_hashes` set, keyed on
`candidate.folder_hash`. Hash is unique per candidate by
construction (different audio_files lists hash differently).
- `_folder_snapshots` retyped + rekeyed to `folder_hash`. Siblings
no longer overwrite each other's mtime tracking.
- Both touched in lockstep — comments document why path-keyed
dedup breaks for sibling candidates.
Test added (`test_sibling_candidates_have_unique_folder_hashes`):
verifies 3-album loose root produces 3 candidates with distinct
folder_hashes. If a future change breaks the invariant, the test
fails before the silent-skip regression ships.
Verification:
- 178 imports tests pass (8 new this commit + 170 pre-existing
this branch)
- Ruff clean
- Still scoped to import flow
Two related bugs in `AutoImportWorker._scan_directory` surfaced
during real-world testing of the chaotic-staging case (user dropped
loose tracks from multiple albums at staging root, alongside
intact album subfolders):
Bug 1 — Loose files bundled into one fake "album"
When loose audio files existed at a level, the scanner built ONE
FolderCandidate from all of them regardless of their album tags.
On a chaotic staging root with tracks from 3+ different albums,
the identifier picked the most-common album tag and the matcher
left every other album's tracks unmatched (or mis-attributed via
filename + position guessing).
Bug 2 — Subfolders silently ignored when root has loose files
The scanner only recursed into non-disc subfolders when there were
NO loose files at the parent level. So a layout like:
Staging/
loose1.flac (processed via the loose-files path)
Other Album Folder/ (silently ignored — never scanned)
would skip the album subfolders entirely. Common pattern when a
user moves a few tracks out of an album folder while leaving the
rest of the parent album folder intact, OR when other album
folders sit alongside a partially-extracted album.
Fix:
`_build_loose_file_candidates` (new method) reads each loose file's
`album` tag and groups by normalised album name. Each group becomes
its own FolderCandidate so a chaotic staging root produces one
candidate per album — identifier + matcher run cleanly per album.
Untagged loose files become individual single candidates. Disc
folders at the same level attach to whichever loose-file group's
album tag matches the disc-folder tracks; standalone disc folders
(no matching loose group) get their own multi-disc candidate.
The scanner now ALSO always recurses into non-disc subdirectories,
even when the current level has loose files. So album subfolders
sitting beside loose tracks get processed independently in their
own recursive scan.
Behavior preservation:
- Single-album loose-files staging (every file shares one album tag,
no parallel disc folders) → one FolderCandidate, identical to
pre-fix behavior. Pinned by `test_single_album_loose_files_still_one_candidate`.
- Disc-only directory (no loose files, only Disc 1/Disc 2 subdirs)
→ one multi-disc FolderCandidate, identical to pre-fix. Pinned
by `test_disc_only_directory_still_works`.
7 new tests in `tests/imports/test_auto_import_scanner_grouping.py`:
- Multiple-album loose root → multiple candidates
- Untagged loose files → individual singles
- Single-album loose-files regression guard
- Subfolders recursed even when root has loose files
- Disc folder attaches to matching loose group by album tag
- Disc folder with no matching loose group → standalone candidate
- Disc-only directory regression guard

Cin-pass on the MBID/ISRC fast-paths + duration-gate work.
Three small but real gaps closed.
Gap 1 — Real-file tag reader integration test
(tests/imports/test_auto_import_tag_reader_real_files.py, 6 tests):
The matcher unit tests use dict fixtures, which prove the algorithm
handles the right shapes once tags are read. They DON'T prove the tag
reader itself extracts the right values from real files. Mutagen's
easy-mode key normalisation (across FLAC / MP3 / M4A) is the exact
spot a future mutagen version could silently drift and break the
fast paths in production while every unit test stays green.
These tests write real FLAC files via mutagen (using the same
`_make_minimal_flac` pattern from `test_album_mbid_consistency.py`)
and assert `_read_file_tags` extracts:
- Picard's `MUSICBRAINZ_TRACKID` (lowercase normalisation in reader)
- `ISRC` (uppercase normalisation in reader; matcher strips
formatting at compare time)
- "track/total" parsing (TRACKNUMBER='5/12' → 5)
- Duration via `audio.info.length` from synthesised STREAMINFO
- Graceful empty-default return for tagless files
- Graceful empty-default return for invalid audio (not a crash)
Acknowledged gap (carried forward): MP3 + M4A integration coverage
not added — mutagen docs say easy-mode normalisation is identical
across all three formats, but only FLAC is pinned here. Followup
candidate.
Gap 2 — Source-aware duration dispatch
(core/imports/album_matching.py, 4 tests in test_album_matching_exact_id.py):
The previous `_track_duration_ms` helper used a magnitude heuristic
("anything below 30000 is seconds, convert × 1000") to decide
whether a track's duration was in seconds or ms. That worked for
typical tracks but had a real edge case: an actual sub-30-second
Spotify track (intros, interludes, skits) would be detected as
seconds and converted to 8.5 hours, breaking the duration sanity
gate.
Replaced with deterministic source-aware dispatch:
- Spotify / iTunes / Qobuz / HiFi / Hydrabase → ms (canonical)
- Deezer / Discogs / MusicBrainz → seconds, × 1000
- Tidal classified as ms (album-tracks endpoint convention; flagged
in code comment as needing real-world verification — defensive
if wrong)
- Magnitude heuristic kept as fallback for unknown / missing source
(mocked test data without source field)
Tests pin all four paths: confirmed-ms source, confirmed-seconds
source, unknown source falls back to heuristic, and the regression
case (sub-30s real track on a known-ms source — must not be
× 1000-converted).
Gap 3 — Cross-disc consolation rationale
(tests/imports/test_album_matching_helper.py, 1 test):
The `CROSS_DISC_POSITION_WEIGHT = 0.05` magic number had no test
proving it was load-bearing. Anyone could have set it to 0 thinking
"strict matching is better" without realising it would silently
break a real scenario.
New test (`test_cross_disc_consolation_is_load_bearing_for_imperfect_titles`)
constructs the exact case the consolation exists for: file has the
right title spelling but the metadata source returns a slightly-
different version (e.g. "Auntie Diaries" file vs "Auntie Diaries
(Remix)" track), AND the file's disc tag is wrong while the track
number agrees. Title sim ~0.78 × 0.45 = ~0.35 (below
MATCH_THRESHOLD 0.4). Without the 5% consolation → file goes
unmatched. With it → ~0.40, just clears.
The test doesn't justify "why 0.05 specifically" — that's still a
tuned knob, not a measured value. But it forces a deliberate
decision if someone wants to drop it: failing this test gives them
the "you broke imperfect-title cross-disc matching" message
explicitly.
Verification:
- 10 new tests across 3 files, all pass
- 35 album-matching tests total now (including pre-existing 17 +
18 fast-path)
- Full suite: 2321 passed, 1 pre-existing flaky timing test
(`test_watchdog_warns_about_stuck_workers` — passes in isolation,

identical (verified by grep on every changed file)
Brings the auto-import matcher to picard / beets / roon parity by
reaching for the existing AcoustID-grade infrastructure (typed Album
foundation, integrity check thresholds) and layering id-based exact
matches on top of the fuzzy scorer. Picard-tagged libraries now land
every track with full confidence on the first pass.
Three layered phases in `core/imports/album_matching.match_files_to_tracks`:
1. **MBID exact match** — file has `musicbrainz_trackid` tag, source
returns the same id → instant pair, full confidence, no fuzzy
scoring. Picard's primary identifier; per-recording.
2. **ISRC exact match** — file has `isrc` tag, source returns the same
id → same fast-path, slightly lower priority than mbid (isrc can
be shared across remasters). Both ids normalised before compare
(uppercase + strip dashes/spaces for isrc, lowercase for mbid).
3. **Duration sanity gate** — files in the fuzzy phase whose audio
length differs from the candidate track's duration by more than
`DURATION_TOLERANCE_MS` (3s, matching the post-download integrity
check) are rejected before scoring runs. Defends against the
cross-disc / cross-release / wrong-edit problem the integrity
check used to catch only AFTER the file had already been moved +
tagged + db-inserted.
Tag reader (`_read_file_tags`) extended:
- Reads `isrc` (uppercased, strip / / spaces normalisation deferred
to matcher)
- Reads `musicbrainz_trackid` as `mbid` (lowercased)
- Reads `audio.info.length` and converts to `duration_ms` to match
the metadata-source convention
Metadata-source layer (`_build_album_track_entry`) extended:
- Propagates `isrc` from top-level OR `external_ids.isrc` (spotify
shape — would otherwise be stripped before reaching the matcher)
- Propagates `musicbrainz_id` from top-level OR `external_ids.mbid`
/ `external_ids.musicbrainz`
- Without this layer, fast paths would silently never fire in
production even though unit tests pass — pinned by
`test_album_track_entry_propagates_isrc_and_mbid_from_source`
18 new tests in `tests/imports/test_album_matching_exact_id.py`:
- Direct: `find_exact_id_matches` with mbid, isrc, isrc normalisation,
mbid > isrc priority, spotify-shape `external_ids.isrc`, no-id
empty result, file-used-at-most-once
- Direct: `duration_sanity_ok` within / outside tolerance, missing
durations defer
- End-to-end via `match_files_to_tracks`: mbid match short-circuits
fuzzy scoring, id-matched files excluded from fuzzy phase, duration
gate rejects wrong-disc collisions in fuzzy phase, normal matches
pass through the gate, missing durations fall through, deezer
seconds-vs-ms conversion, full picard-tagged 10-track album via
mbid only
- Production-shape: `_build_album_track_entry` propagates isrc + mbid
from spotify-shape (`external_ids.isrc`) AND itunes-shape (top-
level `isrc`)
Verification:
- 35 album-matching tests pass total (17 helper + 18 fast-path)
- 23 multi-disc tests still pass after the extension (additive)
- Full suite: 2311 passed (+18 new), 1 pre-existing flaky timing test
failure (`test_watchdog_warns_about_stuck_workers` — passes in
isolation, fails only in full-suite runs, unrelated to this PR)
- Ruff clean
For users:
- Picard / Beets / Mp3Tag-tagged libraries (anyone who's organised
their music) get instant perfect-confidence matches every time.
- Soulseek-tagged downloads (which usually carry isrc when sourced
via metadata-aware soulseekers) get the fast path too.
- Naively-named files with no useful tags fall through to the
improved fuzzy + duration-gated path — same correctness as before
for the common case, much harder for the matcher to confidently
pair the wrong file.
- One step closer to standalone-DB feature parity with plex /
jellyfin / navidrome scanners. Acoustid fingerprint fallback
(for files with NO useful tags AND no MBID/ISRC) is the next
followup PR.
Cin-pass on the #524 + multi-disc fixes. Pre-merge polish.
Lifts: `core/imports/album_matching.py`
`AutoImportWorker._match_tracks` was a 100+-line method buried in a
1400-line class. Testing it required monkey-patching `_read_file_tags`
+ mocking the metadata client just to exercise the matching algorithm.
Per Cin's "lift logic out of monolithic classes" pattern (same shape
as the album-info builders / discography / quality scanner lifts),
moved the dedup + scoring into `core/imports/album_matching.py` as
pure functions over already-fetched data.
Helper exposes:
- Constants for every match weight (TITLE_WEIGHT, ARTIST_WEIGHT,
POSITION_WEIGHT, NEAR_POSITION_WEIGHT, CROSS_DISC_POSITION_WEIGHT,
ALBUM_WEIGHT, MATCH_THRESHOLD). Magic numbers killed.
- `dedupe_files_by_position(audio_files, file_tags, *, quality_rank)` —
position-keyed quality dedup.
- `score_file_against_track(file_path, file_tags, track, *,
target_album, similarity)` — pure per-(file, track) scorer.
- `match_files_to_tracks(audio_files, file_tags, tracks, *,
target_album, similarity, quality_rank)` — full matching with
greedy best-per-track + first-come-first-serve over deduped files.
Worker shrinks from 100 lines of inline algorithm to 8 lines that
fetch tags + delegate to the helper.
Tests added (26 new across 3 files):
`tests/imports/test_album_matching_helper.py` (19 tests):
- Constants pin: weights sum to 1.0, threshold above position-only
- `dedupe_files_by_position`: quality wins, cross-disc preserved,
tag-less files passed through, first-wins on equal quality
- `score_file_against_track`: perfect-agreement = 1.0, position
needs both disc+track, near-position only same-disc, missing
artist tags handled, disc field aliases (Spotify/Deezer/iTunes),
filename fallback when title tag missing
- `match_files_to_tracks`: happy path, file used at-most-once,
below-threshold left unmatched
- Edge case Cin would flag: tag-less file with strong filename title
matches multi-disc album track via title alone (perfect-name
scenario works); tag-less file with weak filename title against
multi-disc API correctly stays unmatched (the behavior delta from
the disc-aware fix — pinned so future readers see it's intentional)
`tests/test_import_album_match_endpoint.py` (3 tests):
- Backend warning fires when source missing from match POST
- No warning fires on the legit path (catches noisy-warning regression)
- Endpoint actually forwards source/name/artist to the payload
builder (catches "logging the right warning but doing the wrong
lookup" regression)
`tests/test_import_page_album_lookup_pattern.py` (4 tests):
- Source-text guard for the import-page #524 fix in stats-automations.js.
Until the file is modularized enough for a behavioral JS test (under
the existing tests/static/*.mjs pattern), regex-based assertions pin:
the `_albumLookup` field exists, the click handler reads from it,
both card renderers populate it before emitting onclick, and the
cache stores `source` per entry. Caveat documented in the test
module docstring.
Verification:
- All 26 new tests pass.
- Existing multi-disc tests (test_auto_import_multi_disc_matching.py)
still pass after the lift — proves the helper is behavior-equivalent
to the inline implementation it replaced.
- Full suite: 2293 passed, 1 flaky-timing failure
(test_library_reorganize_orchestrator.py::test_watchdog_warns_about_stuck_workers
— passes in isolation, fails only in full-suite runs, pre-existing,
unrelated to this PR).
- Ruff clean.
Notes for the reviewer:
- The frontend stats-automations.js JS test is structural-only.
Behavioral JS testing for that file requires modularizing the
~7k-line monolith first — out of scope for this fix.
- The cross-disc 5% consolation bonus is a small behavior change for
users with weak/missing tag info on multi-disc albums. Pinned
explicitly in `test_tagless_file_with_weak_title_unmatched_in_multidisc`
so the trade-off is visible: correct multi-disc matching wins over
optimistic position-only matching that produced wrong-disc files.
Caught while live-testing the #524 fix with kendrick lamar
mr morale & the big steppers (3 discs). User dropped discs 1+2
loose in staging root + disc 3 in its own folder, every file
perfectly tagged with disc_number/track_number/title — only 9
tracks ended up in the library, the rest got integrity-rejected
and quarantined.
Two related bugs in `AutoImportWorker._match_tracks`:
1. **Quality dedup keyed on track_number alone.** The dedup loop
kept `seen_track_nums[track_number] = file` and dropped any later
file with the same number, treating it as a quality duplicate.
On a multi-disc release where every disc has tracks 1..N, that
collapses the album to one disc's worth of files BEFORE the
matcher runs. User's 18 loose disc-1+disc-2 files reduced to 9
before any title/disc info was even consulted.
2. **Match scoring ignored disc_number.** The 30% track-number bonus
fired whenever `ft[track_number] == track_num` regardless of disc.
File with tag (disc=2, track=6, "Auntie Diaries", 281s) got the
full bonus matching API track (disc=1, track=6, "Rich Interlude",
103s) — wrong file → wrong destination → integrity check correctly
rejected and quarantined the file. Same for tracks 7, 8, 9.
Fix:
- Dedup keys on `(disc_number, track_number)` tuples — multi-disc
files with parallel numbering all survive.
- Match scoring's 30% bonus only when BOTH disc AND track agree.
Cross-disc same-track-number collisions get a small 5% consolation
bonus so title similarity has to carry the match (covers cases
where tag disc info is missing or wrong).
- API track disc_number read from `disc_number` (Spotify) /
`disk_number` (Deezer) / `discNumber` (iTunes) defaulting to 1.
4 new pinning tests in `tests/imports/test_auto_import_multi_disc_matching.py`:
- 18-file 2-disc regression case (dedup preserves all)
- (disc=2, track=6) file matches API (disc=2, track=6) track, not
the disc-1 same-numbered track
- Single-disc albums still match normally (no regression)
- Quality dedup within a single (disc, track) position still picks
higher-quality format (.flac over .mp3)
Verification:
- 2268 full pytest suite passes (+4 new), 1 skipped, 0 failed

Same branch as the #524 fix because both surfaced from the same
import session — easier reviewer context if they ship together.
Previous commit split _check_ffmpeg into a side-effect-free
_locate_ffmpeg + the original auto-download _check_ffmpeg, and moved
__init__ to call _locate_ffmpeg. That alone wasn't enough — caught
the gap during a deeper audit:
is_configured() → is_available() → _check_ffmpeg() (with download)
The orchestrator registry, download engine, and the orchestrator's
own configured_clients() all probe is_configured() polymorphically at
boot. So when tests import web_server, the registry probes
youtube.is_configured() → is_available() → _check_ffmpeg() →
DOWNLOAD. My __init__ change didn't help because the registry boot
fires the same code path right after.
Real fix: gate the download branch inside _check_ffmpeg itself.
Returns False (and logs a warning) when running under pytest or when
SOULSYNC_NO_FFMPEG_DOWNLOAD=1. End users on a fresh install still get
auto-download on first real YouTube use (gate is off in production).
Container is unaffected (system ffmpeg via apt is found on PATH, the
download branch never runs).
Three detection paths in _auto_download_disabled():
- SOULSYNC_NO_FFMPEG_DOWNLOAD env var (explicit opt-out for CI /
build steps that want to disable outside pytest)
- PYTEST_CURRENT_TEST env var (set by pytest per-test — covers
in-test-body call path)
- 'pytest' in sys.modules (covers calls fired during pytest collection
/ import phase, BEFORE the per-test env var is set — which is
exactly when registry.py probes is_configured() at web_server
import time)
Verified by inspecting tools/ after a full suite run — empty (was
~388 MB after a single test_tidal_auth_instructions.py run before
the gate). Container behavior unchanged: shutil.which('ffmpeg')
returns /usr/bin/ffmpeg from the apt-installed package, so the
download branch is never reached anyway.
5 new pinning tests:
- pytest-in-sys.modules detection works
- PYTEST_CURRENT_TEST env detection works
- SOULSYNC_NO_FFMPEG_DOWNLOAD env detection works
- _check_ffmpeg returns False (no urlretrieve, no tools/ dir created)
when gate is on and ffmpeg is missing — pinned by trapping
urlretrieve to AssertionError so a regression blows up loud
- _locate_ffmpeg never triggers download or creates tools/ —
pinned by trapping both urlretrieve AND Path.mkdir on tools-prefixed
paths
2264 passed (+5), 1 skipped, 0 failed.
Three follow-on fixes to the manual-search candidates modal once people
started actually using it:
1. NDJSON streaming. Manual search waited for every source to return
before showing anything. Now streams one event per source as each
completes — header line, source_results per source, done terminator.
Frontend appends rows incrementally via response.body.getReader().
2. Manual picks no longer auto-retry on failure. New _user_manual_pick
flag set on the task in /download-candidate. Both monitor retry
paths (not-in-live-transfers stuck + Errored state) bail on the
flag. Surfaces the failure to the user instead of silently picking
a different candidate via fresh search.
3. Non-Soulseek manual picks (youtube/tidal/qobuz/hifi/deezer/
soundcloud/lidarr) no longer stuck at "downloading 0%" forever. The
live_transfers IF branch now marks manual-pick tasks failed
directly when the engine reports Errored, instead of deferring to
the monitor (which bails on manual picks). Engine fallback in else
branch covers the rare race where the orchestrator's pre-populated
transfer lookup is missing the entry.
Plus a deadlock fix discovered along the way: the new failure path
synchronously called on_download_completed while holding tasks_lock,
which itself re-acquires the same Lock — non-reentrant
threading.Lock self-deadlocked the polling thread. While wedged, every
other endpoint that needed the lock (including /candidates → other
failed rows couldn't open modals) hung waiting. Moved completion
callbacks onto a daemon thread so the lock releases first.
Plus failed/not_found/cancelled rows are now ALWAYS clickable (not
just when the auto-search cached candidates) — the modal carries the
manual search bar, which is the user's recourse for empty results.
Plus manual download worker now runs on a dedicated thread instead of
competing with the batch's 3-worker missing_download_executor pool —
saturated batches no longer queue manual picks indefinitely.
All scoped to manual picks via the _user_manual_pick flag — auto
attempt flow byte-identical to before. Engine fallback gated on the
flag too so auto attempts in the else branch keep the original
do-nothing behavior (safety valve handles the stuck-forever case).
Also dropped _handle_failed_download from web_server.py — defined
but had no callers (dead code).
17 new unit tests pin the gate behavior:
- engine fallback: Errored/Cancelled/Succeeded/InProgress transitions,
manual-pick gate, terminal-state skip, soulseek skip, missing
download_id skip, engine returning None, orchestrator exception
- monitor: manual-pick skips not-in-live-transfers retry + Errored
retry
- IF-branch end-to-end: Errored marks failed, "Completed, Errored"
hits failure branch, auto attempts defer to monitor
Manual-search endpoint tests rewritten for NDJSON: 11 cases (validation,
single-source dispatch, parallel "all" dispatch, one-event-per-source
streaming shape, unconfigured-source skip + reject, header metadata,
per-source exception isolation).
Full suite 2259 passed, 1 skipped.
When an auto-download fails or returns "not found" with leftover
candidates, the user can already click the status cell to open a
modal showing those candidates and pick a different one. This adds
a manual search bar to that modal — type any query, hit search,
get a fresh round of results without having to bail out and start
over from the main search page.
Solves the case where the auto-query was bad (featured artist not
in title, parentheticals like "(Remastered 2019)" tripping the
matcher, slight artist-name variants, transliteration) but the
file genuinely exists on the source.
Frontend (downloads.js)
- Added a manual-search section above the existing auto-candidates
table inside the candidates modal.
- Source picker is smart per download mode:
- Single-source mode (soulseek-only / youtube-only / etc) shows
a "Searching X" label, no dropdown.
- Hybrid mode shows a dropdown with "All sources" default + every
configured source. Picking "All" runs parallel searches across
them and tags each result row with its source badge.
- Only configured sources show up; unconfigured are hidden.
- Validation: button disabled until query length >= 2, "Type at
least 2 characters" hint until threshold crosses.
- Loading state on search button while the request is in flight.
- Manual results render in a separate table above the existing
auto-candidates table, using the same row template (file /
quality / size / duration / user / ⬇ button) so the renderer
helper is shared.
- Click ⬇ reuses the existing `downloadCandidate(taskId, candidate,
trackName)` flow — same retry path, same AcoustID verification
when the file lands, no shortcut around the safety net.
- Re-running the search with a different query replaces the
previous manual results.
Backend (web_server.py)
- Extended `GET /api/downloads/task/<id>/candidates` response with:
- `download_mode` (e.g. 'hybrid', 'soulseek')
- `available_sources` (list of configured source IDs + labels)
- `source` field on each candidate (purely additive — frontend
auto-renderer ignores it on legacy code paths, manual-search
renderer uses it for the badge)
- Added `POST /api/downloads/task/<id>/manual-search`:
- Body: `{ query, source: 'all' | <source_id> }`
- Validates query length (>=2 trimmed) → 400
- Validates source against the configured-sources gate → 400
(rejects unconfigured sources even when explicitly named)
- For 'all': parallel `ThreadPoolExecutor` dispatch across every
configured download source, merged results
- For specific source: just that source
- Returns same shape as `/candidates` so the frontend renderer
is reused
- New module-level helpers: `_STREAMING_SOURCE_NAMES`,
`_infer_candidate_source`, `_serialize_candidate`,
`_list_available_download_sources`. The existing `/candidates`
endpoint also goes through `_serialize_candidate` so the source
badge is consistent across both flows.
Behavior preserved
- Existing modal layout / candidates table / ⬇ button are
byte-identical when the user doesn't use manual search.
- `downloadCandidate()` JS function untouched.
- `/candidates` and `/download-candidate` endpoints
backwards-compatible — only NEW fields added, nothing changed
or removed.
Tests
`tests/test_manual_search_endpoint.py` — 10 tests:

throwing doesn't kill the merged result)
2242/2242 full suite green (was 2232 + 10 new). Ruff clean.
JS parses clean.
Four selection-quality fixes on the SoulSync-made discover playlists.
None change public method signatures; all are tightenings on what's
already there.
(1) Diversity for Hidden Gems + Discovery Shuffle
Both used to be `RANDOM() LIMIT N` with no diversity. Could return
50 tracks from one artist or 20 from one album if the discovery
pool happened to be skewed. Both now over-fetch 3x and run the
existing `_apply_diversity_filter`:
- Hidden Gems: max 2 per album, 3 per artist
- Discovery Shuffle: max 2 per album, 2 per artist (tighter — shuffle
should feel maximally varied)
(2) Source-aware popularity thresholds
`popularity >= 60` for "Popular Picks" and `popularity < 40` for
"Hidden Gems" was Spotify-shaped (0-100 scale). Deezer writes its
`rank` value into that column (often six-digit integers); iTunes
writes nothing meaningful. For Deezer-primary users:
- Popular Picks pulled essentially everything (rank >= 60 = all)
- Hidden Gems pulled essentially nothing (rank < 40 = none)
New `_get_popularity_thresholds(source)` helper returns per-source
values:
- Spotify: (60, 40) — the existing 0-100 scale
- Deezer: (500_000, 100_000) — ballpark from real rank values
- iTunes / unknown: (None, None) — skip the popularity filter
entirely, fall back to random + diversity
`get_popular_picks` and `get_hidden_gems` now consult the helper.
When threshold is None they skip the popularity SQL filter. Diversity
+ ID gate still apply.
(3) Push genre keyword filter into SQL
`get_genre_playlist` used to fetch `limit=1_000_000` rows into Python
then run a substring keyword filter on `artist_genres`. Bad on big
discovery pools.
Now the keyword OR chain is generated as SQL placeholders:
AND (artist_genres LIKE ? OR artist_genres LIKE ? OR ...)
Each placeholder gets `f'%{keyword.lower()}%'` via `extra_params`.
`fetch_limit` drops back to `limit * 10`. `_genre_matches` Python
helper deleted (only intra-file caller; verified via grep).
Parent-genre expansion via `GENRE_MAPPING` preserved — keywords list
feeds the LIKE chain unchanged.
(4) Filter out tracks already in library
Discovery pool can include tracks the user already owns. Hidden Gems
/ Shuffle / Popular Picks shouldn't surface those.
`_select_discovery_tracks` gained `exclude_owned: bool = True`
parameter. When True, adds a correlated NOT EXISTS subquery against
the `tracks` table covering all 3 source IDs:
AND NOT EXISTS (
SELECT 1 FROM tracks t WHERE
(t.spotify_track_id IS NOT NULL AND t.spotify_track_id = discovery_pool.spotify_track_id)
OR (t.itunes_track_id IS NOT NULL AND t.itunes_track_id = discovery_pool.itunes_track_id)
OR (t.deezer_id IS NOT NULL AND t.deezer_id = discovery_pool.deezer_track_id)
)
Note column-name asymmetry: tracks.deezer_id vs
discovery_pool.deezer_track_id. Inline comment marks the trap. All
5 public discovery methods automatically benefit (default True).
Seasonal Playlist doesn't go through the helper so it's unaffected
(curated content, dedup is wrong intent there).
Tests
12 new tests in `tests/test_personalized_playlists_id_gate.py` (27
total in the file):
- Hidden Gems + Discovery Shuffle apply diversity (cap proven by
inserting 10 same-artist + same-album rows and asserting return
count ≤ per-album cap)
- Popularity thresholds: Spotify (60, 40), Deezer larger scale,
iTunes None / None
- Popular Picks skips threshold filter when None
- Genre playlist pushes filter to SQL (parent + child genre expansion)
- Owned-track exclusion: filtered when match, kept when no match,
opt-out flag works
- Deezer column-name asymmetry pinned (regression footgun)
Test fixture re-added the minimal `tracks` table (4 columns: id,
spotify_track_id, itunes_track_id, deezer_id) — only what the new
NOT EXISTS subquery needs to join. Plus `insert_library_track`
helper.
Verification
- 27/27 in this test file pass (15 prior + 12 new)
- 2232/2232 full suite green

LOC delta:
- core/personalized_playlists.py: 1030 → 1101 (+71)
- tests/test_personalized_playlists_id_gate.py: 352 → 616 (+264)
The original gate baked into `_select_discovery_tracks` only checked
Spotify + iTunes:
AND (spotify_track_id IS NOT NULL OR itunes_track_id IS NOT NULL)
For Deezer-primary users, discovery_pool rows have populated
`deezer_track_id` but NULL Spotify + NULL iTunes IDs. The gate
filtered every row out — Time Machine, Genre Browser, Hidden Gems,
Discovery Shuffle, Popular Picks all rendered "no tracks found" for
every tab on every Deezer-primary install.
Extended the gate to include `deezer_track_id` and added that column
to the standard SELECT column tuple. `_build_track_dict` already
exposed `deezer_track_id` in its output shape, so frontend rendering
needed no changes.
Regression pinned via new test
`test_discovery_helper_accepts_deezer_only_id_rows` — inserts a row
with NULL Spotify + NULL iTunes but a populated `deezer_track_id`
and asserts it survives the gate.
2220/2220 full suite green.
Owner decision: not worth shipping. The four library-driven personalized
sections were stubbed returning [] for ages because their schema
prereqs didn't exist; the prior commit re-enabled them by routing
through a new `_select_library_tracks` helper. Owner reviewed and chose
to delete the sections entirely instead.
Removed everywhere:
- `core/personalized_playlists.py` — `get_recently_added`,
`get_top_tracks`, `get_forgotten_favorites`, `get_familiar_favorites`
+ the `_select_library_tracks` helper (no other callers; verified
via grep).
- `web_server.py` — 4 route handlers
(`/api/discover/personalized/recently-added`, `top-tracks`,
`forgotten-favorites`, `familiar-favorites`).
- `webui/index.html` — 4 `<div class="discover-section">` blocks
(`#personalized-recently-added`, `#personalized-top-tracks`,
`#personalized-forgotten-favorites`,
`#personalized-familiar-favorites`).
- `webui/static/discover.js` — 4 load functions
(`loadPersonalizedRecentlyAdded`, `loadPersonalizedTopTracks`,
`loadPersonalizedForgottenFavorites`, `loadFamiliarFavorites`),
plus their entries in `loadDiscoverPage`'s Promise.all, plus
4 module-level state vars + 6 dead branches across
`openDownloadModalForDiscoverPlaylist` / `startDiscoverPlaylistSync`
and the sync-progress / rehydrate dispatchers.
- `webui/static/helper.js` — 4 tooltip / docs entries.
- `webui/static/sync-spotify.js` — 1 stale rehydrate dispatcher
branch (`discover_familiar_favorites`) caught during the global
grep pass.
- `tests/test_personalized_playlists_id_gate.py` — 3 library-method
tests + the test infrastructure that supported them
(`tracks` schema, `insert_library_track` helper). Documentation
header updated to reflect the deletion.
Net: -527 / +2 lines across 7 files.
What stays:
- Daily Mixes (also in personalized package, intentionally paused —
separate decision).
- Popular Picks + Hidden Gems + Discovery Shuffle (alive, not
affected by this deletion).
- All 14 tests in the personalized-playlists test file still pass.
- The PersonalizedPlaylistsService lift from the prior commit
(`_select_discovery_tracks` etc) — those are still in active use
by the surviving discovery_pool methods.
DISCOVER_TRACK_SELECTION_REVIEW.md at repo root contains historical
references to the four deleted endpoints. Treated as historical
context (same policy as WHATS_NEW), left alone.

JS parses clean, ruff clean.
User-facing bug found in the discover-page audit: multiple sections
(hidden gems, discovery shuffle, popular picks, decade browser,
genre browser) had no `WHERE (spotify_track_id IS NOT NULL OR
itunes_track_id IS NOT NULL ...)` gate. Tracks with no source IDs
in the discovery pool got displayed, the user clicked download, the
download silently failed because there was nothing to look up.
Lift + gate
`PersonalizedPlaylistsService` had 5 selection methods that all shared
the same shape — connect to DB, run a SELECT against `discovery_pool`
with different WHERE clauses, optionally apply diversity, return
list of track dicts. ~366 lines of business logic, ~55% of which was
repeated boilerplate.
Three new private helpers consolidate everything:
- `_select_discovery_tracks(*, source, extra_where, extra_params,
order_by, fetch_limit, extra_columns)` — shared SELECT against
`discovery_pool`. The mandatory ID gate is hard-coded into the
WHERE clause: no opt-out flag, every method inherits it for free.
Plus the source filter and the blacklist filter — same shape every
selector needs.
- `_apply_diversity_filter(tracks, *, max_per_album, max_per_artist,
limit)` — per-album / per-artist cap loop, returns trimmed list.
Lifted from the inline duplicates in decade / genre / popular_picks.
- `_compute_adaptive_diversity_limits(tracks, *, relaxed=False)` —
step-function tiers based on unique-artist count. `relaxed=True`
gives the slightly looser limits the genre playlist used vs the
decade playlist.
Re-enable 4 library methods
`get_recently_added`, `get_top_tracks`, `get_forgotten_favorites`,
`get_familiar_favorites` were all stubs (`return []`) because they
predated the schema columns they need. Schema now has them:
`tracks.created_at`, `tracks.play_count`, `tracks.last_played`, and
the source ID columns added in earlier work.
New `_select_library_tracks(*, where_clause, params, order_by, limit)`
helper mirrors the discovery selector but targets the `tracks` table
joined against `albums` + `artists`. Mandatory ID gate lives in the
helper too: every library method automatically rejects rows where
spotify_track_id, itunes_track_id, deezer_id,
musicbrainz_recording_id, AND audiodb_id are all NULL.
Selection rules:
- `get_recently_added` — ORDER BY created_at DESC
- `get_top_tracks` — WHERE play_count > 0 ORDER BY play_count DESC
- `get_forgotten_favorites` — WHERE play_count > 5 AND last_played
< (now - 90 days) ORDER BY play_count DESC
- `get_familiar_favorites` — WHERE play_count BETWEEN 3 AND 15
Tests
`tests/test_personalized_playlists_id_gate.py` — 17 tests pinning:
- `_select_discovery_tracks` filters NULL-id rows, honors source +
blacklist + extra_where
- `_apply_diversity_filter` caps per-album + per-artist + stops at
limit
- `_compute_adaptive_diversity_limits` returns the right tier for
unique-artist count + relaxed flag
- All 5 discovery methods (decade, popular_picks, hidden_gems,
discovery_shuffle, genre is exercised via the helper) reject
NULL-id rows
- All 4 library methods reject NULL-id rows + honor their
play-count rules
Behavior preserved
Same diversity tiers, same over-fetch multipliers (10x for decade /
genre, 3x for popular_picks), same `popularity DESC, RANDOM()`
ordering, same `popularity >= 60` / `< 40` thresholds, same
blacklist filter. Public method signatures unchanged — `web_server.py`
needs zero edits.
Net file: 1089 → ~1170 LOC (helpers + docstrings), but actual
business logic across the 9 methods went from ~418 lines down to
~195 (-53%).
2222/2222 full suite green (was 2205 + 17 new). Ruff clean.
Three changes tightening the controller before opening the PR.
DROP MAGIC `extractItems` DEFAULTS
Controller used to auto-pull `data.items` / `data.albums` /
`data.artists` / `data.tracks` / `data.results` when no extractor
was supplied. Removed the fallback chain — every section now MUST
provide an explicit `extractItems(data) => array`. Validated at
register-time so misuse fails immediately, not silently on first
load against an endpoint that happened to return two arrays.
Cin standard: explicit > implicit. Magic key-grabbing could pick
the wrong one in edge cases (e.g. an endpoint returning both
`data.albums` and `data.results` would have grabbed albums when
the section actually wanted results).
All 10 existing controller call sites already passed explicit
extractors, so no migration churn — this is purely tightening the
contract for future sections.
REPLACE `renderItems` NULL-RETURN CONVENTION WITH `manualDom: true`
Your Albums and similar sections that delegate to existing renderers
that target a CHILD element of `contentEl` used to signal "leave the
container alone" by returning null/undefined from `renderItems`. That
convention is easy to confuse with an accidental missing-return error.
Replaced with an explicit `manualDom: true` config flag. Renderer is
still called for its side-effects, controller just skips the innerHTML
swap. Clearer intent at the call site. Updated `loadYourAlbums` to
use the new flag.
PIN THE CONTROLLER CONTRACT WITH JS TESTS
Added `tests/static/test_discover_section_controller.mjs` — 32 tests
covering the controller's lifecycle contract:
- Config validation (every required field, mutual exclusivity of
fetchUrl/data, type checks on contentEl)
- Happy-path fetch → parse → render
- Empty state (default empty render, hideWhenEmpty + sectionEl,
success=false treated as empty, custom isSuccess override)
- Stale state (fires when isStale returns true, wins over empty,
custom renderStale override)
- Error state (HTTP non-ok, fetch throws, showErrorToast fires
window.showToast, default off doesn't fire)
- No-fetch `data:` mode (value + function form, doesn't call fetch)
- manualDom mode (skips innerHTML swap, still calls renderer)
- Callable `fetchUrl` (resolved at load time, refresh re-resolves)
- Load coalescing (concurrent loads share one fetch)
- Refresh bypasses coalescing (re-fires fetch every call)
- Hook error containment (throwing renderer/onSuccess hooks don't
crash the controller)
Runs via Node's stable built-in `--test` runner — no package.json,
no jest/vitest dependency, no compile step. Just `node --test`.
Pytest wrapper at `tests/test_discover_section_controller_js.py`
shells out to node and asserts clean exit, so the JS tests fail
the regular pytest sweep if the controller contract drifts.
Skipped gracefully when node isn't available or is < 22.
Closes the "controller is a contract, pin it at the test boundary"
gap that Cin would have flagged on review.
VERIFICATION
- 2205/2205 full pytest suite green (was 2204 + 1 new wrapper)
- 32/32 `node --test` pass on the controller test file directly
- ruff clean
- node --check clean on all touched JS files
Closes#513 (s66jones).
The artist detail page already showed a "Popular on Last.fm" sidebar —
list of an artist's top tracks by playcount, with a play button per row
but no download action. Issue #513 wanted a way to grab those tracks
the same way zotify let users grab "top X songs" without pulling the
full discography.
Pulls from the configured primary metadata source (Spotify
`artist_top_tracks`, Deezer `/artist/{id}/top`) when available, falls
back to the existing Last.fm display-only mode for sources that don't
expose popularity ranking (iTunes / Discogs / MusicBrainz). Source
label in the section title shifts to match.
Each row gets a hover-revealed download button that wishlists the
single track via the existing /api/add-album-to-wishlist endpoint
(preserves the track's real album metadata, so the wishlist worker
later places the file in its proper album folder).
A "Download All" footer button opens the standard download modal in
PLAYLIST context, not album context — the virtual playlist_id is
`top_tracks_<source>_<artistId>` which doesn't match any of the
album-prefix checks in `startMissingTracksProcess` (downloads.js).
That keeps `is_album_download=false`, so the master worker doesn't
inject a wrapper context as `_explicit_album_context`. Each track
downloads using its own real album metadata, files land in proper
per-album folders on disk (not a fake "Top Tracks" folder).
Backend additions:
- `SpotifyClient.get_artist_top_tracks(artist_id, country, limit)` —
wraps `spotipy.artist_top_tracks`, returns up to 10 tracks for the
market (Spotify's API cap). UI-side limit trim only.
- `DeezerClient.get_artist_top_tracks(artist_id, limit)` — wraps
`/artist/{id}/top?limit=N`, converts Deezer's raw shape to the same
Spotify-compatible dict layout (id, name, artists, album with
album_type / total_tracks / images, duration_ms, track_number,
disc_number) so downstream code doesn't branch on source.
- `GET /api/artist/<id>/top-tracks` — dispatches to whichever client
matches the primary source. Resolves per-source artist IDs from the
DB row first (matching what /discography already does) so a Spotify
ID in the URL still works when Deezer is primary, and vice versa.
Returns `{success, source, tracks, resolved_artist_id}` on hit;
`{success: False, reason: 'unsupported_source' | 'spotify_not_authenticated'
| 'deezer_unavailable' | 'no_tracks_found'}` on miss so the frontend
can decide whether to fall through to Last.fm.
Frontend:
- `_loadArtistTopTracks` tries the metadata source first, falls
through to the legacy `/api/artist/0/lastfm-top-tracks` call if the
source can't deliver. Section title and per-row UI shift based on
which source answered.
- New per-row `.hero-top-track-download` button (hover-revealed).
- New `.hero-top-tracks-download-all` footer button — only visible
when metadata-source mode rendered the list (Last.fm fallback hides
it since rows have no track IDs to download).
Tests: 10 new tests pin the client methods —
- Spotify: returns track list, honors UI limit cap, returns empty when
unauthed / artist_id missing / API throws.
- Deezer: shape conversion to Spotify-compatible dict, empty when no
data / artist_id missing, limit clamping at upper bound, default
fallback when limit=0, malformed entries skipped.
The Flask endpoint dispatcher itself isn't covered by the new test
file because importing web_server at test-collection time spins up
worker threads that race with caplog-using tests elsewhere in the
suite (specifically test_library_reorganize_orchestrator). Endpoint
verified manually; the underlying client methods (the load-bearing
logic) are covered.
2204/2204 full suite green (was 2194 + 10 new).
Discord report (corruption [BWC]): downloads coming through as the
instrumental cut when a vocal track was requested. The verification
step's `_normalize` function strips parentheticals and version-suffix
tags ("(Instrumental)", "- Live", etc) so legitimate name variations
don't false-fail the title-similarity check. That also means "In My
Feelings" and "In My Feelings (Instrumental)" both normalize to "in
my feelings", title similarity is 1.0, and the wrong cut passes
verification.
Detect the version label on each side BEFORE normalization runs. If
the expected and matched recordings disagree on version (one is
original, the other is instrumental / live / acoustic / remix /
etc), return FAIL — the fingerprint identified a real song, just
not the version the caller asked for.
Reuses `MusicMatchingEngine.detect_version_type` so the same regex
patterns the pre-download Soulseek matcher applies also drive
post-download verification. No duplicated tables.
Also gates the secondary fallback scan, so a wrong-version variant
sitting in the same fingerprint cluster can't win the loop after
the best match has already been version-rejected.
6 tests pin the behavior:
- instrumental returned for vocal request → FAIL
- vocal returned for instrumental request → FAIL
- live vs acoustic → FAIL
- matching versions on both sides → PASS
- original-to-original happy path → PASS (regression guard)
- secondary scan skips wrong-version recordings → not PASS

Discord report: Duplicate Detector card said "372 findings" and Cover
Art Filler said "60 findings", but clicking the Findings tab's Pending
filter showed 0. User read it as "findings aren't being created" —
looked like a detector bug.
Actual cause: the badge sourced ``last_run.findings_created``
(historical "found in last scan") without considering current state.
After the user (or bulk-fix automation) resolved or dismissed those
findings, they no longer appeared on the Pending tab — but the badge
kept showing the last-scan number in red urgent styling.
Backend was correct end-to-end: detectors create pending rows,
bulk-fix moves them to resolved, Findings tab filters by status.
Only the badge display lied about current state.
Fix:
- ``RepairWorker._get_pending_count_by_job()`` — single SQL aggregation
returning ``{job_id: pending_count}`` for every job with pending
findings. O(1) lookup per job instead of N round trips.
- ``get_all_job_info()`` calls it once per request and adds
``pending_findings_count`` to each job's API response.
- ``enrichment.js`` job card now branches on the count:
- ``> 0`` → red ``"X pending"`` badge (urgent, action needed)
- ``= 0`` AND last scan found something → muted grey ``"X found in
last scan"`` (historical context, no action needed)
- New CSS class ``.repair-flow-badge.findings-historical`` for the
muted slate color so the two states are visually distinct.
User-visible result with the screenshotted state (372 dup / 60 cover-
art findings, all resolved):
- Before: red "372 findings" / "60 findings" — implied 432 things to
do, but Findings tab showed 0 pending
- After: grey "372 found in last scan" / "60 found in last scan" —
the badge text tells the user the count is historical, no surprise
when Pending is empty
Tests: 3 new tests in ``tests/test_create_finding_dedup_counter.py``
pin the per-job pending count helper:
- returns ``{job_id: count}`` based on status='pending' rows only;
resolved + dismissed rows excluded
- empty dict when no pending findings exist
- gracefully returns ``{}`` on DB error (badge falls back to
historical count via the existing JS ``or 0`` safety)
2188/2188 full suite green. Pure UI/state-display fix — no detector
logic, no backend behavior change.
GitHub issue #499 (@bafoed). Big initial sync of Spotify playlists
worked for 2-3 hours then downloads silently stopped:
- 3 active tasks stuck in "Searching" state, replaced every ~10 min
by different ones
- slskd UI showed no actual searches happening
- Debug log: orphaned-task count grew over time, no jobs executed
- Container restart was the only fix (bought another 2-3 hours)
- Not a rate limit (rates showed 0/min)
Root cause: ``core/soulseek_client.py`` constructed
``aiohttp.ClientSession()`` with no timeout at four sites. When slskd
hung on a request (overloaded, transient network blip, internal
stall), the HTTP call blocked indefinitely — and the worker thread
blocked with it. The download executor only has
``ThreadPoolExecutor(max_workers=3)``, so once 3 worker threads were
wedged on hung calls, no further downloads could start.
Batch-level "stuck detection" (10-minute timer in
``check_batch_completion_v2``) was correctly marking tasks
``not_found`` and trying to start replacements, but the executor pool
was exhausted — replacements queued forever inside the executor with
no thread to run them. Symptom: tasks rotating every ~10 min at the
batch level while the underlying executor stayed wedged.
Fix: bounded ``aiohttp.ClientTimeout`` (total 120s, connect 15s,
sock_read 60s) on every slskd ``ClientSession`` construction. Module-
level constant ``_SLSKD_DEFAULT_TIMEOUT`` so the four sites stay in
lockstep — future sites get the same protection by reusing the
constant.
Why these timeouts are safe:
- Every slskd API call is metadata-level (search submission, status
polls, download enqueue, transfer state queries). None stream
files — slskd handles file transfer via its own peer-to-peer
infrastructure entirely outside our HTTP requests.
- Legitimate metadata calls finish in seconds. 120s ceiling is
~50× the normal latency.
Timeout handling:
- ``asyncio.TimeoutError`` caught explicitly BEFORE the generic
``except Exception`` — surfaces "slskd timed out" specifically in
logs (debuggable instead of buried as "Error making API request").
- Returns None to the caller (same code path as a 5xx response or
any other failure). No new error path; callers already handle
None as "request failed".
- Worker thread unblocks immediately → executor pool stays healthy
→ downloads keep flowing.
Sites updated:
- ``_make_request`` (general /api/v0/ helper, line 152) — used for
every slskd API operation
- ``_make_direct_request`` (non-/api/v0/ helper, line 235)
- ``_explore_api_endpoints`` Swagger fetch (line 1566) — diagnostic
- ``_explore_api_endpoints`` per-endpoint probe (line 1617) —
diagnostic
Tests: 3 new tests in ``tests/downloads/test_soulseek_pinning.py``
pin:
- ``_SLSKD_DEFAULT_TIMEOUT`` is bounded (total set, ≤300s ceiling,
connect ≤60s) — guards against future regressions that drop or
unbound the timeout
- ``_make_request`` returns None on ``asyncio.TimeoutError`` rather
than raising — pins the caller contract
- ``_make_direct_request`` returns None on ``asyncio.TimeoutError``
2185/2185 full suite green.
Closes#499.
GitHub issue #500 (@bafoed). Library Reorganize repair job moved
album tracks to single-template paths because of a fragile
classification heuristic. Concrete symptom: a track at
``Surf Curse/Surf Curse - Nothing Yet (2017)/01 - Christine F.flac``
got proposed for a move to
``Surf Curse/Surf Curse - Christine F/Surf Curse - Christine F.flac``
(single template) instead of staying under the album folder.
Root cause: the job had its own tag-reading + transfer-folder-walk +
template-application implementation. The classification was
``is_album = (group_size > 1)`` where ``group_size`` was the count
of same-album tracks currently sitting in the transfer folder being
scanned. Two failure modes:
- only one track of an album was in the transfer folder (rest already
moved to the library, or not yet downloaded), or
- album tags varied slightly across tracks (e.g. ``"Buds"`` vs
``"Buds (Bonus)"``)
Either case gave a 1-element group → routed through the SINGLE
template → wrong destination.
Rewrite — delegate to the per-album planner the artist-detail
"Reorganize" modal already uses:
- ``core.library_reorganize.preview_album_reorganize`` for path
computation (DB-driven, knows the album has N tracks regardless of
how many sit in transfer; album-vs-single is structurally correct)
- ``core.reorganize_queue.enqueue_many`` for apply mode; the queue
worker dispatches via ``reorganize_album`` which handles file move
+ post-processing + DB update + sidecar through the same code path
the per-album modal uses
Job's per-album loop:
- iterate albums for the active media server only (matches the artist-
detail modal's scope; multi-server users won't have the job touch
the inactive server's files at paths they can't see)
- preview each album, catch exceptions per-album so one bad row
doesn't abort the scan
- branch on planner status:
- ``no_album`` / ``no_tracks`` (race: album deleted mid-scan) →
skip silently
- ``no_source_id`` (album never enriched) → emit ONE album-level
"needs enrichment first" finding (vs N per-track findings cluttering
the UI)
- ``planned`` → filter mismatched tracks (matched + new_path +
not unchanged + file_exists), emit per-track findings (dry-run)
or collect album for bulk enqueue (apply)
- bulk enqueue at end of loop using the queue's correct return-shape
(``{'enqueued': N, 'already_queued': M, 'total': K}``)
What's gone (~500 LOC):
- ``_read_tag_metadata`` / ``_get_audio_quality`` / transfer-folder walk
- ``_load_album_years`` / ``_lookup_years_from_api`` (planner does this)
- ``_apply_path_template`` / ``_build_path_from_template``
- direct ``shutil.move`` + sidecar move logic (queue handles)
- the fragile ``is_album = group_size > 1`` heuristic — structurally gone
- ``move_sidecars`` setting (no longer applicable; queue's post-process
re-downloads cover art at the destination)
What stays:
- dry-run vs apply toggle
- ``file_organization.enabled`` gate
- stop / pause respect
- progress reporting
- findings for the UI
Cleaner separation of concerns:
- this job: DB-known tracks at wrong paths (active server only)
- ``orphan_file_detector``: files on disk with no DB entry
- ``dead_file_cleaner``: DB entries pointing to nonexistent files
Tests: 12 tests in ``tests/test_library_reorganize.py`` pin the
delegation contract — every status branch, every track-filter case,
exception handling, apply-mode enqueue payload, active-server scope,
estimate-scope shape. Three obsolete ``_lookup_years_*`` tests removed
(year handling moved to planner).
Closes#500 (the misclassification half — orphan + dead-file are
downstream sync-gap symptoms, separate concern).
GitHub issue #501 (@Tacobell444). After manually matching an album to
a specific source ID via the match-chip UI, clicking "Enrich" on that
album would fuzzy-search by name and overwrite the manual match with
whatever the search returned — or revert the match status to
``not_found`` if name search missed. Reorganize then read the now-
wrong ID and moved files to the wrong destination.
Root cause was in the per-source enrichment workers'
``_process_*_individual`` methods. Several workers (Spotify, iTunes)
ran search-by-name unconditionally with no check for an existing
stored ID. Others (Deezer, Tidal, Qobuz) skipped on existing-ID but
without refreshing metadata — preserved the ID but didn't actually
honor the user's intent of "use this match to pull fresh data".
Cin-shape lift: same fix needed in 5 workers, so extracted the shared
behavior into ``core/enrichment/manual_match_honoring.py``:
honor_stored_match(
db, entity_table, entity_id, id_column,
client_fetch_fn, on_match_fn, log_prefix,
) -> bool
Per-worker variability (DB column name, client fetch method, response
shape) plugs in via callbacks. Workers call the helper at the top of
``_process_album_individual`` / ``_process_track_individual``; if it
returns True, the manual match was honored and the search-by-name
fallback is skipped. If False (no stored ID, fetch failed, or empty
response), the worker's existing search-by-name flow runs as before.
Workers wired:
- spotify_worker — album + track (was overwriting; now honors)
- itunes_worker — album + track (was overwriting; now honors)
- deezer_worker — album + track (was skip-on-id; now refreshes)
- tidal_worker — album + track (was skip-on-id; now refreshes)
- qobuz_worker — album + track (was skip-on-id; now refreshes)
Workers left alone (already correct):
- discogs_worker — already had inline stored-ID fast path that
refreshes metadata. Same behavior, just inline; refactoring to use
the shared helper would be churn for zero behavior change.
- audiodb_worker — same — inline fast path with full metadata refresh.
- musicbrainz_worker — preserves existing MBID and marks status,
which is the correct behavior for MB (the MBID itself is the match
payload — no separate metadata fetch).
- lastfm_worker / genius_worker — name-based services with no
source-specific IDs to honor. Inherent re-search per call.
Reorganize fixed indirectly — it always honored stored IDs correctly
via ``library_reorganize._extract_source_ids``. The "Reorganize broken"
symptom was downstream of broken Enrich corrupting the stored ID.
Tests:
- ``tests/enrichment/test_manual_match_honoring.py`` — 11 tests
pinning the shared helper contract: stored-ID fast path, no-ID
fallthrough, empty-string treated as no ID, missing row, fetch
exception caught and falls through, fetch returns None falls
through, callback exceptions propagate, configurable table +
column, defensive table-name whitelist.
- Per-worker wiring NOT tested individually — the workers depend
on live DB / client objects that are heavy to mock. The shared
helper's contract is pinned; per-worker call sites are short
enough to verify by code review.

GitHub issue #503 (@hadshaw21). Adding a HiFi instance via downloader
settings popped up ``no such table: hifi_instances`` even though
"Test Connection" and "Check All Instances" both worked.
Root cause: ``MusicDatabase._initialize_database`` runs every
``CREATE TABLE`` + every migration step inside one sqlite transaction.
Python's sqlite3 module doesn't autocommit DDL by default, so if any
later migration step throws on a user's specific DB shape (e.g. an
old volume from a prior SoulSync version with quirky schema state),
the WHOLE batch rolls back — including the ``hifi_instances`` CREATE
that ran earlier in the function. The user's next boot retries init,
hits the same migration failure, rolls back again. The ``hifi_instances``
table never lands no matter how many restarts.
Fix: defensive lazy-create. New ``_ensure_hifi_instances_table(cursor)``
helper runs ``CREATE TABLE IF NOT EXISTS`` on demand, called immediately
before every CRUD operation that touches ``hifi_instances``:
- ``get_hifi_instances`` / ``get_all_hifi_instances`` (read)
- ``add_hifi_instance`` / ``remove_hifi_instance`` (CRUD)
- ``toggle_hifi_instance`` / ``reorder_hifi_instances`` (CRUD)
- ``seed_hifi_instances`` (defaults seed)
Idempotent — costs one no-op CREATE check when the table is already
present, fully recovers from a broken init state. Read methods now
return empty instead of raising when init failed; write methods work
end-to-end.
Doesn't paper over the underlying init issue (still worth tracking
which migration step breaks for which user DB shapes — separate
concern) but makes HiFi instance management self-healing in the
meantime.
Tests:
- 7 obsolete tests that pinned ``raises sqlite3.OperationalError``
removed — that contract is no longer correct
- 7 new tests pin the lazy-create behavior: every CRUD method works
against a DB that's missing the ``hifi_instances`` table, verifying
the table gets created and the operation completes
2162/2162 full suite green. Pure additive — no behavior change for
users with a healthy DB; affected users get back to working hifi
instance management.
Closes#503.
Followup to the all-libraries-mode commit. Without dedup, a Plex Home
family where two users both have "Drake" in their music libraries
would see "Drake" twice in SoulSync's library list — Plex returns
distinct ratingKeys for each section's copy of the same artist.
Dedup design — applied selectively, NOT everywhere:
- ``_dedupe_artists(artists)``: groups by lowercased title, picks
the canonical entry by ``leafCount`` (more tracks wins). Active
ONLY in all-libraries mode; single-library mode is a no-op fast
path with zero behavior change.
- ``_dedupe_albums(albums)``: same but keys on
(lowercased parentTitle, lowercased title) so two artists with
identically-titled albums (e.g. self-titled releases) stay
separate.
Applied to:
- ``get_all_artists()`` — public listing for the library view
- ``get_library_stats()`` — count matches what user sees in the list
Deliberately NOT applied to:
- ``get_all_artist_ids()`` / ``get_all_album_ids()`` — these feed
removal detection (compare returned ratingKey set against DB-linked
ratingKeys to decide what's been removed). Deduping here would falsely
flag non-canonical ratingKeys as "removed" and prune SoulSync's DB
tracks that are linked to them. Pinned by two CRITICAL tests.
- ``_all_tracks()`` — track count stays raw because the same track
in two sections IS two distinct files / Plex entries, not a logical
duplicate.
- ``_search_general()`` and ``search_tracks`` Stage 1/2 — search
results stay raw so cross-section matches aren't lost. Stage 1
may miss cross-section tracks for the same artist but Stage 2's
server-wide track search catches them.
Logging: when raw vs deduped artist counts differ, ``get_all_artists``
logs both so users can see "Found 4697 artists across all music
sections (4521 unique after cross-section dedup)" — surfaces the
overlap clearly.
Tests: 8 new tests in test_plex_all_libraries.py pin:
- canonical pick by leafCount (artists + albums)
- case-insensitive name match
- single-library no-op path (zero behavior change for those users)
- album dedup keys on (artist, title) so different-artist same-title
albums stay separate
- ``get_all_artists`` listing applies dedup
- ``get_all_artist_ids`` does NOT dedup (CRITICAL — removal detection)
- ``get_all_album_ids`` does NOT dedup (CRITICAL — removal detection)
- ``get_library_stats`` uses deduped counts for artists/albums but
raw count for tracks
Existing pre-stat test updated to use distinct mock instances —
``[MagicMock()] * 5`` creates five references to one mock which now
correctly collapses under dedup.
71/71 media_server tests green, 2162/2162 full suite green.
Honest known limitation acknowledged in WHATS_NEW + version modal:
write-back (genre / poster / metadata updates) targets one
ratingKey at a time — only updates the canonical section's copy of
an artist if it exists in multiple. Other section's copy stays
unchanged. Document and revisit if it matters.
GitHub issue #505 (PopeBruhLXIX): users with multiple Plex music
libraries (e.g. one per Plex Home user, or two folder roots split
across separate library sections) only saw one library inside SoulSync
because the connection settings forced you to pick a single library
section. SoulSync's PlexClient stored exactly one ``self.music_library``
section reference and every read scanned only that one.
This change adds an opt-in "All Libraries (combined)" dropdown option
that flips the client into a server-wide read mode where every read
method (``get_all_artists`` / ``get_all_album_ids`` /
``search_tracks`` / ``get_library_stats`` / etc) dispatches through
``server.library.search(libtype=...)`` instead of querying a single
section. One Plex API call replaces N per-section iterations; Plex
handles the aggregation server-side.
Implementation:
- ``ALL_LIBRARIES_SENTINEL`` (``'__all_libraries__'``) — module-level
constant used as the saved DB preference value when the user picks
the synthetic "All Libraries" entry. Detection is one string compare
in ``_find_music_library`` / ``set_music_library_by_name``. Existing
preferences (real library names) are unaffected.
- ``self._all_libraries_mode`` (private flag) + ``is_all_libraries_mode()``
(public accessor for external callers). When True, ``music_library``
may stay None — ``is_fully_configured()`` recognizes the mode and
still returns True so dispatch sites don't bail.
- New private helpers ``_can_query``, ``_get_music_sections``,
``_all_artists``, ``_all_albums``, ``_all_tracks``, ``_search_general``,
``_search_artists_by_name``. Single dispatch point for the
section-vs-server branch — every read method funnels through them
so future drift fails at one place.
- New public helpers for downstream callers:
- ``get_recently_added_albums(maxresults, libtype)`` — used by
DatabaseUpdateWorker's deep-scan recent-content sweep
- ``get_recently_updated_albums(limit)`` — same
- ``get_music_library_locations()`` — returns folder roots, used
by web_server.py's file-path resolver
- ``trigger_library_scan`` and ``is_library_scanning`` fan out across
every music section in all-libraries mode.
- ``get_available_music_libraries`` prepends a synthetic
``{'title': 'All Libraries (combined)', 'value': sentinel}`` entry
ONLY when more than one music library exists. Single-library users
don't get the extra option. ``value`` field is the canonical
identifier the frontend submits to ``/api/plex/select-music-library``
(real libraries: title; synthetic: sentinel string). Backward-
compatible — entries without ``value`` fall back to ``title``.
Three crash points fixed in downstream consumers (would have failed
during a deep scan after the user picked all-libraries mode):
1. ``database_update_worker.py:411`` — bailed out with "No music
library found in Plex" because ``not self.media_client.music_library``
evaluated True in all-libraries mode (music_library is None there).
Now uses ``is_fully_configured()`` which recognizes the mode.
This was the root cause of the deep scan never starting.
2. ``database_update_worker.py:_get_recent_albums_plex`` — reached
``self.media_client.music_library.recentlyAdded()`` /
``.search()`` directly, AttributeError in all-libraries mode.
Now routes through the new helper methods.
3. ``web_server.py:10947`` (file-path resolver) — accessed
``music_library.locations``; gated on ``music_library`` truthy so
it didn't crash, but silently skipped all-libraries-mode locations.
Now uses ``get_music_library_locations()`` which unions across
sections.
Plus polish:
- ``/api/plex/clear-library`` also resets ``_all_libraries_mode``
so a fresh "select library" flow doesn't inherit stale mode state.
- ``/api/plex/music-libraries`` surfaces "All Libraries (combined)"
as ``current_library`` when in mode (settings UI displays correctly).
- Frontend ``loadPlexMusicLibraries`` uses ``library.value || library.title``
so the sentinel-keyed option submits the sentinel string, not the
human-readable label. Pre-select match handles both paths.
Honest tradeoffs (documented as known limitations):
- Same artist appearing in multiple Plex sections shows as separate
entries in SoulSync (no dedup). Plex returns distinct ratingKeys
for each. Cosmetic; revisit if it bites users.
- Write-back (genre / poster updates) targets one ratingKey at a time
— only updates that section's copy. Other sections' copies stay
unchanged.
- All-libraries mode includes any audiobook library that Plex
classifies as ``type='artist'``. Edge case, opt-in only.
Tests: 21 new tests in tests/media_server/test_plex_all_libraries.py
pin both single-library mode (regression guard) and all-libraries mode
for every refactored method. Existing test_plex_pinning.py fixture
updated to initialize the new flag. 63/63 media_server tests green,
2148/2148 full suite green.
Followup on the previous Enhance refactor. Multi-source parallel text
search closed the worst case (users with no Spotify/Deezer getting
"unknown artist - unknown album - unknown track" wishlist entries),
but text search itself is still fragile against messy library tags:
"Title (Live)", featured artists in the artist field, etc. Download
Discography never had this problem because it resolves albums by stable
ID, not by name.
Enhance now does the same thing for tracks: for every metadata source
the user has configured, if the library track has the corresponding
stored ID (spotify_track_id / deezer_id / itunes_track_id / soul_id),
call client.get_track_details(stored_id) directly and convert to the
wishlist payload. First success wins. The user's configured primary
source is tried first so a Deezer-primary user gets Deezer payloads on
the wishlist entry (correct cover art / album shape) even when other
sources also have stored IDs for the same track.
Multi-source parallel text search stays as the fallback for tracks
with no stored IDs (e.g. manually imported, never enriched). Empty-
field rejection still gates the wishlist add.
Implementation:
- _STORED_ID_COLUMNS: source name → DB column mapping
(Discogs intentionally omitted — release-based, no per-track IDs)
- _enhanced_to_wishlist_payload: converts the get_track_details
intermediate "enhanced" shape (artists as [str]) to wishlist shape
(artists as [{'name': str}]). Spotify's raw_data is already in
wishlist shape, returned as-is when detected (preserves full
album.images that the enhanced top-level fields drop)
- _try_direct_lookup_all_sources: iterates sources preferred-first,
calls get_track_details on each that has both a stored ID and a
configured client, returns first complete-metadata payload
- spotify_client field removed from ArtistQualityDeps (no longer
used — Spotify direct lookup now flows through the generic
per-source loop using the entry from search_sources)
- _try_upgrade_to_rich_payload removed (was Spotify-only with broken
shape semantics for non-Spotify sources; search-fallback now uses
_build_payload_from_track consistently)
- get_primary_source() consulted to set the per-call preferred source
for direct-lookup priority
Also fixed a stale UI string: the Enhance modal toast read "Matching
tracks to Spotify and adding to wishlist..." regardless of which
sources were actually configured. Now reads "Matching tracks across
metadata sources...".
Tests:
- _build_deps mirrors web_server._resolve_search_sources: passing
spotify=spotify_obj auto-prepends ('spotify', spotify_obj) to
search_sources (Spotify is always added when configured in prod)
- 5 new tests pin the direct-lookup behavior:
- test_direct_lookup_via_deezer_id_skips_text_search
- test_direct_lookup_via_itunes_id_skips_text_search
- test_direct_lookup_prefers_user_primary_source
- test_direct_lookup_falls_through_to_text_search_when_no_stored_ids
- test_direct_lookup_failure_falls_through_to_text_search
- Reframed enhanced-format and search-fallback tests for the new
payload-build path (no album-image side call, search-fallback uses
_build_payload_from_track consistently)
- 22/22 quality tests green, 2133/2133 full suite green.
Track Redownload had been doing parallel multi-source metadata search
across every configured source the whole time; Enhance Quality was
running a single-source primary fallback that returned junk matches
with empty fields when the primary was iTunes (Discord report:
"unknown artist - unknown album - unknown track" wishlist entries
for users with neither Spotify nor Deezer connected).
Lift the redownload search into core/metadata/multi_source_search.py
and point both flows at it. Same scoring, same per-source query
optimization (Deezer's structured artist:/track: form), same
current-match flagging via stored source IDs.
ArtistQualityDeps now takes get_metadata_search_sources (returns
[(name, client), ...] for every configured source) instead of the
single-primary get_metadata_fallback_client + get_metadata_fallback_source.
Spotify direct-lookup stays as a fast-path optimization (only Spotify
exposes get_track_details(id) returning rich raw payload); when it
doesn't fire, the multi-source parallel search picks the cross-source
best match. Empty-field matches still rejected before wishlist add.
Tests: _build_deps helper updated to accept the new search_sources
contract while preserving fallback_client/fallback_source ergonomics.
Reframed tests for the new semantics — direct-lookup is no longer
gated on Spotify being the active primary; failure reason now lists
every searched source. Added a test pinning the no-sources-configured
prompt. 17/17 quality tests green, 2128/2128 full suite green.
Discord report: clicking Enhance Quality on an artist with neither
Spotify nor Deezer connected added tracks to the wishlist as
"unknown artist - unknown album - unknown track".
Root cause was structural. core/artists/quality.py had a hardcoded
Spotify-direct → Spotify-search → iTunes-fallback chain that ignored
the user's configured primary metadata source. When Spotify wasn't
connected, every track fell through to an iTunes-only fallback that
occasionally returned matches with empty fields (cleared the 0.7
confidence threshold but missing artist / album / title). Those
empty strings propagated through the wishlist payload normalizer's
truthy-check passthrough at core/wishlist/payloads.py:77-80 and the
UI rendered them as "Unknown" defaults.
Rewrote the flow source-agnostic:
- ArtistQualityDeps gains get_metadata_fallback_source. Flow resolves
the user's active primary source once up front.
- New _build_payload_from_track helper produces the Spotify-shaped
wishlist payload from any source's Track object — single place
that knows how to construct it (replaces the duplicate construction
in the Spotify-search and iTunes-fallback paths).
- New _search_match helper does generic confidence-scored search
against any client implementing search_tracks(query, limit). Same
0.7 threshold, same album-bonus weighting as before.
- New _has_complete_metadata validator rejects matches with empty
title / album / artists before they reach the wishlist.
- _spotify_direct_lookup kept as a Spotify-only optimization (only
Spotify exposes get_track_details(id) returning rich raw payload);
other sources fall through to search.
- Failure reason now names the active source: "No usable {source}
match — connect another metadata source for better coverage".
Result: Discogs users get a Discogs search. Hydrabase users get a
Hydrabase search. iTunes users get an iTunes search with empty-field
rejection. Spotify keeps its direct-lookup fast path.
6 new tests pin the architectural change:
- Primary-source dispatch routes to the configured client (Discogs,
not Spotify) when Spotify isn't primary
- Spotify direct-lookup is gated on Spotify being the active primary
(skipped when Discogs is configured even if track has spotify_track_id)
- Empty title / album / artists fields all reject the match
- Failure reason names the active source
Pre-review audit found premature abstraction + lying docstrings.
Cut what isn't used, made the rest match what's actually shipped.
(1) Engine: dropped 7 cross-server dispatch wrappers that had ZERO
production callers (ensure_connection / get_all_artists /
get_all_album_ids / search_tracks / trigger_library_scan /
is_library_scanning / get_library_stats / get_recently_added_albums).
Every consumer reaches the active client directly via
sync_service._get_active_media_client() or engine.client(name).
Engine surface shrinks to client(name) / active_client() /
active_server / is_connected() (the one wrapper that has callers —
4 dashboard status sites) / configured_clients() / reload_config().
~150 lines deleted, 5 dead-method tests removed.
(2) Contract Protocol body trimmed to match REQUIRED_METHODS exactly
(is_connected, ensure_connection, get_all_artists, get_all_album_ids).
The other 5 methods that were declared in the Protocol
"required" section weren't actually required — Plex doesn't
implement get_recently_added_albums, Jellyfin doesn't implement
search_tracks, SoulSync doesn't implement most of them. Static
contract now matches runtime conformance test. Optional methods
moved to a KNOWN_PER_SERVER_METHODS data-only listing with audited
per-server coverage notes — discoverability without false promises.
(3) Engine module docstring + __init__.py docstring no longer
overclaim "33+ chains collapsed" — only 4 uniform-shape chains
were collapsed; ~18 server-specific chains stay explicit per the
"lift what's truly shared" standard. Phrasing now matches reality.
(4) types.py docstring claimed TrackInfo.from_jellyfin_dict and
TrackInfo.from_navidrome_dict exist as classmethods. They don't —
only from_plex_track / from_plex_playlist do. Jellyfin and Navidrome
construct TrackInfo inline at their call sites today. Docstring
now honest about that + flags the lift as a clean followup.
(5) Engine line 95 comment "backward-compat for source-specific
reaches" was misleading — there is no legacy alternative being
preserved; engine.client(name) IS the canonical access pattern.
Section header rewritten.
Tests: 2121 pass (was 2126; -5 dead-method pin tests).
Five tightening passes anticipating Cin / JohnBaumb's review nits:
(1) Engine no longer reaches into ``registry._instances`` private
attr. New public ``MediaServerRegistry.set_instance(name, client)``
method — engine constructor calls it for the ``clients=`` pre-built
case so internal storage stays encapsulated.
(2) Engine module docstring no longer overclaims. Originally said it
"Replaces the historic 33+ if/elif chains" — but only the four
uniform-shape ``is_connected`` chains were collapsed. The 19 chains
that do server-specific work (Plex raw API vs Jellyfin / Navidrome
client methods returning different shapes) stay explicit per the
"lift what's truly shared" standard. Docstring rewritten to say
exactly that.
(3) Per-method exception swallows upgraded from ``logger.debug`` to
``logger.warning``. Returning safe defaults stays the right behavior
for a read-side engine (Plex offline shouldn't crash the app), but
silent debug-level swallowing made debugging hard — JohnBaumb pushed
the download engine to surface real errors. Same treatment here:
default still safe, but the warning tells you Plex is down.
(4) ``_safe_init_media_client`` in web_server.py now logs the
exception type + traceback. Broad ``except Exception`` is still
intentional (any failure means that one server can't be used; the
others stay up) but the boot log now distinguishes config errors
(ConnectionError, AuthenticationError) from import / dependency
failures.
(5) Two new tests pin the encapsulation + fallback contracts:
- ``test_engine_with_empty_clients_dict_is_safe_to_use`` — empty
engine returns safe defaults on every method, doesn't raise.
- ``test_engine_uses_registry_set_instance_not_private_attr`` — spy
on registry.set_instance verifies engine uses the public method.
Per-server web_server.py globals (plex_client / jellyfin_client /
navidrome_client / soulsync_library_client) are gone. The engine now
owns the per-server client instances; web_server.py constructs them
inline into the engine init and routes everything through
media_server_engine.client('<name>').
Multi-client consumers refactored to take the engine instead of
separate per-server kwargs:
- services/sync_service.py: PlaylistSyncService.__init__ now takes
media_server_engine. Internal _get_active_media_client resolves the
active server's client through self._engine.client(name) instead of
the per-server self.X_client attributes.
- core/listening_stats_worker.py: ListeningStatsWorker takes
media_server_engine. The plex/jellyfin/navidrome dispatch in _poll
collapses to engine.client(active_server) (gated to those three
servers — SoulSync standalone has no listening data).
- core/web_scan_manager.py: WebScanManager takes media_server_engine
instead of the hand-keyed media_clients dict that drifted out of
sync with the engine.
- core/discovery/sync.py: SyncDeps holds media_server_engine instead
of plex_client / jellyfin_client. Playlist-image dispatch routes
through engine.client(name).
Web_server.py:
- Per-server globals removed from the chained `= None` init line
+ their try/except construction blocks. Replaced with a
_safe_init_media_client(factory, name) helper that captures
per-server init failures + passes the resulting clients straight
into the MediaServerEngine init dict.
- All construction sites (PlaylistSyncService, WebScanManager,
ListeningStatsWorker, SyncDeps, library_check) updated to receive
the engine instead of per-server clients.
Test fixtures (tests/discovery/test_discovery_sync.py) gain a
_FakeMediaServerEngine stub + the SyncDeps build helper passes
that instead of separate plex/jellyfin clients.
Apply the Cin-1 / Cin-2 pattern from the download refactor PR to the
media server engine PR before review.
Cin-1 — explicit inheritance:
- PlexClient, JellyfinClient, NavidromeClient, SoulSyncClient now
explicitly inherit MediaServerClient instead of relying on
structural typing alone. Pre-change a reader of plex_client.py
had no way to know the class was supposed to satisfy the contract.
- Removed the engine + registry re-exports from
core/media_server/__init__.py to break the circular import that
the inheritance change introduced (importing the package now
triggered a chain that loaded clients before their base class
resolved). Submodules import directly: from
core.media_server.engine import MediaServerEngine, etc.
- Conformance test now also asserts isinstance() / issubclass()
against MediaServerClient — drift in any class fails at the test
boundary instead of at runtime.
Cin-2 — generic accessors + singleton:
- engine.configured_clients() — replaces the legacy per-server
`if X and X.is_connected(): clients[name] = X` chains in
web_server.py.
- engine.reload_config(name=None) — generic dispatch, so callers
pass the server name instead of reaching for plex_client.reload_config()
directly.
- get_media_server_engine() / set_media_server_engine() singleton
factory matching the get_metadata_engine() / get_download_orchestrator()
shape. web_server.py boots via set_media_server_engine(...) so
factory + global handle share state.
- 7 new tests pin the accessors + singleton behaviour.
Pinning gaps he flagged after his second pass:
- register_plugin when set_engine() raises: registration must succeed
+ plugin stays in the registry (download() raises later, surfacing
the error to the user via download_with_fallback). Pin so a future
refactor can't accidentally propagate the set_engine exception and
crash boot.
- engine.get_all_downloads exclude actually doesn't invoke the plugin:
ID-only check would pass even if soulseek's get_all was called and
returned []; sentinel proves the plugin isn't touched at all.
- Cancel mid-flight observable from inside _download_sync: existing
tests pin Cancelled-preserve AFTER impl returns, this pins the
contract plugins rely on (engine.get_record reflecting Cancelled
state during the impl thread's polling loop).
- configured_clients() with broken is_configured(): the try/except
guard exists but had no test — broken plugin is silently skipped,
healthy ones still surface.
- Per-source delay independence: YouTube's 3s rate-limit delay must
not block a Tidal download starting in parallel. Companion to the
per-source-locks test.
Two findings from JohnBaumb on the engine refactor.
(1) Every download client returned None when self._engine was None,
just logging an error. The orchestrator's download_with_fallback
treated None as "source declined", so the user got no feedback —
download silently disappeared. Now each client raises a RuntimeError
on the engine-not-wired path. download_with_fallback already catches
plugin exceptions, logs a warning, and tries the next source — so
the visible behavior is "real error in logs + fallback to next
source" instead of "silent drop". Six clients touched (deezer, hifi,
qobuz, soundcloud, tidal, youtube). Pinning tests updated to expect
raise.
(2) Monitor's engine.get_all_downloads() walked every plugin
including soulseek, but the same monitor loop already pulled slskd
transfers via the transfers/downloads endpoint a few lines earlier —
soulseek's records were being fetched twice per tick. Same issue in
web_server.py's get_cached_transfer_data path. Added an exclude
parameter to engine.get_all_downloads(); both call sites now pass
('soulseek',). New test pins the exclude semantic.
Also fixed a stray 8-space over-indent on the for-loop body in
get_cached_transfer_data (cosmetic, JohnBaumb flagged the same
pattern in monitor.py earlier).
Per JohnBaumb: the single state_lock serialized progress callbacks
across every source. Pre-refactor each client owned its own download
lock, so Deezer / YouTube / Tidal workers never blocked each other.
Multi-source concurrent downloads under the unified lock fought for
the same RLock on every progress update.
Replaced the engine-wide state_lock with per-source RLocks. Each
source gets its own lock, lazily created via _source_lock() on first
use (meta-lock guards the create-race). All record mutations
(add/update/update_unless_state/remove/get/iter) take only that
source's lock — Deezer progress updates no longer block Tidal writes.
Cancelled-preserve semantics still hold because cancel + worker
terminal write target the same source, so they share that source's
lock. New test pins lock independence: holding source-A's lock from
one thread does not block a write on source-B from another.
Per JohnBaumb's review: iter_records_for_source() walked every
(source, id) tuple across the entire engine state to filter one
source — O(total_records) instead of O(source_records). Fine in
practice because total active downloads is usually small, but the
shape was wrong.
Switched the engine's _records storage from a single composite-key
dict (Dict[Tuple[str, str], DownloadRecord]) to a nested dict
(Dict[str, Dict[str, DownloadRecord]]). Per-source iteration now
only touches that source's bucket. add/get/update/remove all
adjusted to the nested layout. remove_record drops the empty source
bucket so future iterations don't see stale source keys.
Public surface unchanged. New test pins the empty-bucket-cleanup
behavior.
Three small follow-ups from the Copilot review of the rename PR:
- services/sync_service.py: PlaylistSyncService.__init__'s
download_orchestrator parameter was annotated as SoulseekClient,
which was misleading (the object passed is the DownloadOrchestrator
with .search_and_download_best, .download, etc — not a SoulseekClient).
Switched the import + annotation to DownloadOrchestrator so type
checking + IDE help match reality.
- tests/test_qobuz_credential_sync.py: docstring still referenced the
old soulseek_client global handle; updated to download_orchestrator
to match the rest of the codebase.
- core/downloads/monitor.py: the `for download in all_downloads` body
was over-indented (8 spaces past the for instead of 4) — purely
cosmetic but easy to mis-edit. Re-indented to one level.
The earlier validation-only filter only ran in the auto-search
scoring path. SoundCloud preview snippets still leaked through:
- The candidate-review modal cached raw search results (pre-validation),
so previews were visible and clickable for manual retry — and the
manual-pick download path bypassed validation entirely, downloading
the preview anyway.
- The not-found raw-results cache stored unfiltered top-20s.
Lift the preview filter into a reusable filter_soundcloud_previews()
helper and apply it at every entry point: validation scoring (still),
modal-cache fallback when validation drops everything, and the
not-found raw-results path. Previews now never reach the cache, the
matcher, or the manual-pick UI. Drops candidates < 35s or below half
the expected duration, gated on expected > 60s so genuine short
tracks still pass. 7 new unit tests pin the helper.
Also fixed a silent regression in core/downloads/task_worker.py's
hybrid-fallback path. Cin-5 dropped the per-source attrs from the
orchestrator (orch.soulseek, orch.youtube, etc.), but the fallback
loop still resolved sources via getattr(orch, '<src>', None) — every
lookup silently returned None, so remaining_sources came back empty
and the fallback never ran. Now uses orch.client(name) like the rest
of the codebase. Updated the test fake to expose client() too — the
old test was passing because the loop was effectively dead.
Two architectural cleanups on top of the download engine refactor.
(1) Shared dataclasses move to neutral plugin package.
TrackResult, AlbumResult, DownloadStatus, SearchResult lived in
core/soulseek_client.py for historical reasons — every other plugin
imported them from the soulseek module just to satisfy the contract,
coupling 8 clients to a sibling source for type imports only. Moved
them to the new core/download_plugins/types.py module and updated all
14 import sites across the deezer/hifi/lidarr/qobuz/soundcloud/tidal/
youtube clients, the engine, matching engine, redownload helper, and
tests. Clean break, no backward-compat re-export.
(2) web_server.py boots the orchestrator via the singleton factory.
After construction it now calls set_download_orchestrator(...) so
get_download_orchestrator() returns the same instance the global
handle points at instead of lazily building a separate orchestrator.
Matches the get_metadata_engine() pattern.
The global handle in web_server.py was named soulseek_client for
historical reasons but the type has long been DownloadOrchestrator,
not SoulseekClient. Renamed the global plus every parameter/attribute
that carried the legacy name.
- web_server.py: global var renamed; all 99 references updated.
- api/, core/downloads/*, core/search/*, core/streaming/*,
services/sync_service.py: parameter names, dataclass fields, and
init() arg names renamed.
- Test fixtures (CandidatesDeps, MasterDeps, SearchDeps, etc.) and
the _build_deps helpers updated accordingly.
The core.soulseek_client module path and SoulseekClient class name
(the actual soulseek-only client) are unchanged — only the orchestrator
handle renamed. Module imports of TrackResult/AlbumResult/DownloadStatus
from core.soulseek_client preserved.
Removed the eight backward-compat attribute aliases on the orchestrator
(soulseek, youtube, tidal, qobuz, hifi, deezer_dl, lidarr, soundcloud).
External callers and the orchestrator's own internals now reach clients
through the generic alias-aware client(name) accessor.
- core/downloads/{master,monitor,validation}.py: migrated to client().
Monitor's per-source aggregation loop replaced with a single
engine.get_all_downloads() call.
- core/search/{orchestrator,stream}.py: migrated; stream.py drops the
hand-built mode-to-client dict.
- web_server.py: migrated /api/deezer/arl-* + tidal client lookup.
- core/download_orchestrator.py: internal self.soulseek /
self.deezer_dl reaches now route through self.client(); attr
assignments dropped from __init__; module docstring updated.
- Test fakes (_FakeSoulseek, _FakeSoulseekWithYT) expose client(name)
instead of stuffing per-source attributes.
- Conformance test re-pinned to the client() accessor contract.
Three correctness fixes from kettui's PR review plus the web_server
migration to generic accessors.
- Engine alias map: register_plugin accepts aliases tuple; get_plugin
+ cancel_download resolve through it. Fixes deezer_dl cancels
silently routing to soulseek.
- Orchestrator hybrid_order normalization: _resolve_source_chain
routes raw config names through registry.get_spec() so legacy
deezer_dl entries don't drop deezer from hybrid mode.
- Atomic update_record_unless_state on the engine: holds state_lock
across the check + write. Both _mark_terminal AND the success path
use it now so a Cancelled state set mid-impl can't be clobbered.
- web_server.py: 30 soulseek_client.<source> reaches migrated to
client("<source>"); shutdown-check setup migrated to generic
registry iteration; 4 hifi reload sites use reload_instances('hifi').
- 18 new tests pin every fix.
Cin's review feedback: external callers reach per-source clients
via attribute access (orch.hifi.reload_instances()) — needs
generic accessors so the registry IS the single source of truth.
Adds:
- orch.client(name) — public accessor for a per-source client.
Resolves canonical names (deezer) AND legacy aliases (deezer_dl).
- orch.configured_clients() — returns {name: client} for every
initialized AND is_configured() == True source. Replaces the
6+ if/hasattr/is_configured chain Cin called out:
if hasattr(orch, 'soulseek') and orch.soulseek and \
orch.soulseek.is_configured(): ...
- orch.reload_instances(source=None) — generic dispatch for
source-specific reload calls. Replaces orch.hifi.reload_instances()
with orch.reload_instances('hifi').
- get_download_orchestrator() / set_download_orchestrator()
singleton factory matching Cin's get_metadata_engine pattern in
PR #498. web_server.py can install the orchestrator it builds
at boot so future callers grab via the factory instead of
importing the legacy `soulseek_client` global.
Phase Cin-3/Cin-4 will replace existing call sites; this commit
just provides the surface so those migrations are mechanical.
Suite still green (335 download tests + 6 new generic-accessor
tests).
`MediaServerEngine` reads the active server from config + dispatches
to the corresponding registered client. Per-server reaches still
work through `engine.client(name)`.
Required-method dispatch (is_connected, ensure_connection,
get_all_artists, get_all_album_ids) returns safe defaults when
the active client failed to initialize OR when the method raises.
Optional-method dispatch (search_tracks, trigger_library_scan,
is_library_scanning, get_library_stats, get_recently_added_albums)
checks hasattr first — SoulSync standalone has no
trigger_library_scan or get_library_stats, engine no-ops with
appropriate defaults instead of forcing every client to declare
stub methods.
10 new engine tests pin: active-server resolution, required
dispatch routing, exception safety, missing-optional-method
fallback shape. Suite still green (1951 passed).
Engine isn't on any production code path yet — Phase C migrates
the 33 web_server.py dispatch sites to call engine.method()
instead of hand-branching by active_server name.
5 tests pin the SoulSync standalone client surface — the
structurally-different one (no auth, no API, no library scan).
is_connected just checks os.path.isdir(transfer_path).
ensure_connection reloads config first so the user changing
the transfer_path takes effect without a process restart.
get_all_album_ids returns a set of MD5-hashed string ids
matching cross-server uniform set semantics.
4 tests pin the Navidrome client surface. Auth shape: base_url +
username + password (no token model — salt generated per request).
get_all_album_ids paginates getAlbumList2 and returns a set of
string ids matching cross-server uniform set semantics.
5 tests pin Jellyfin client surface. is_connected requires ALL
four of base_url + api_key + user_id + music_library_id (stricter
than Plex's is_connected). get_all_album_ids returns a set of
string GUID ids matching the cross-server uniform set semantics.
6 tests pin the Plex client surface the engine will dispatch
through after Phase B/C migrations:
- is_connected returns False on no-server, True on server-present
- is_fully_configured requires BOTH server AND music_library
- get_all_artists empty list on not-connected, iterates
music_library.searchArtists() when connected
- get_all_album_ids returns a set of STRING ratingKey values
(coerced from Plex ints so semantics match Jellyfin GUIDs +
Navidrome string ids)
Phase A pinning catches behavior drift during web_server.py
dispatch-site migrations (Phase C) and engine adapter wiring
(Phase B).
`core/media_server/` package with the Protocol contract that
every media server client (Plex, Jellyfin, Navidrome, SoulSync
standalone) satisfies, plus the registry that holds them.
Required methods conservatively limited to the four every server
truly implements today: is_connected, ensure_connection,
get_all_artists, get_all_album_ids. Other generic methods
(search_tracks, trigger_library_scan, get_recently_added_albums,
etc.) are listed as OPTIONAL — present on most servers but not
all (SoulSync has no library-scan API since it walks the filesystem
directly; Jellyfin uses a different search shape). Phase B's
engine adapters route around the gaps with per-server fallback
instead of forcing every client to declare a no-op stub.
Same registry shape as the download plugin registry — single
source of truth for which servers exist + name resolution. Adding
a 5th server (Subsonic, Emby, etc.) becomes one register call
plus the new client class.
5 conformance tests pin every server class implements every
required method. Plan doc at docs/media-server-engine-refactor-plan.md.
Pure additive — no consumer routes through the contract or
registry yet. Suite still green (1921 passed).
Three findings from a final review pass:
1. **Worker clobbered Cancelled with Errored when impl returned
None / raised mid-cancel.** The legacy per-client thread workers
each had a guard (``if state != 'Cancelled': state = 'Errored'``);
the shared worker dropped it. Fix: new ``_mark_terminal`` helper
in BackgroundDownloadWorker reads current state before writing
the terminal one and leaves Cancelled alone. SoundCloud test
updated back to the strict Cancelled-only assertion (had been
loosened to accept Errored as a workaround). Two new pinning
tests catch the regression.
2. **Dead code in engine.py.** ``find_record`` and
``iter_all_records`` had no production callers — only tests.
Removed them. Concurrent-add stress test rewritten to use the
per-source iterator that's actually in use.
3. **Silent ``except Exception: pass`` in cross-source query
methods.** Faithful to legacy behavior (one source failing
shouldn't take down aggregation) but Cin's standard is "log
even when you swallow." Each silent-swallow site now logs at
debug level so the source name + exception are inspectable
without adding warning-level noise.
Suite still green (2049 passed).
`engine.search_with_fallback(query, source_chain, ...)` walks the
chain in order, skips unconfigured / unregistered plugins,
swallows per-source exceptions, and returns the first non-empty
(tracks, albums) tuple. Replaces orchestrator's hand-rolled
hybrid search loop.
`engine.download_with_fallback(username, filename, file_size,
source_chain)` falls through the chain when a source returns
None / raises. Username hint promotes a matching source-chain
entry to head of order. NOT yet wired into orchestrator.download
— today's username comes from a search result and represents
the user's explicit source pick, so silently falling through
would override their choice. Engine method is available for
future callers that want fallback semantics
(search_and_download_best, automation).
Orchestrator gains _resolve_source_chain helper that builds
the ordered list (hybrid_order config, falling back to legacy
primary/secondary pair). Orchestrator.search hands chain off
to engine.search_with_fallback for hybrid mode.
8 new tests pin the fallback semantics: chain ordering,
unconfigured-skip, exception-continue, empty-when-exhausted,
username-hint promotion. Suite still green (2050 passed).
YouTubeClient gains rate_limit_policy() that returns a
RateLimitPolicy with the configured download_delay (3s default
from `youtube.download_delay`). Engine reads this at
register_plugin time + applies to engine.worker.
set_engine still re-applies the delay so runtime reload_settings
updates flow through the same pathway. Other sources keep the
default policy (concurrency=1, delay=0) which matches their
current behavior — no migration needed beyond YouTube which is
the only source with a non-default download throttle today.
New pinning test asserts the policy shape (delay=3.0, concurrency=1).
Suite still green (2042 passed).
`core/download_engine/rate_limit.py` introduces a per-source
policy declaration: download_concurrency + download_delay_seconds.
Plugins declare via `RATE_LIMIT_POLICY` class attribute or a
`rate_limit_policy()` method.
Engine applies the declared policy to engine.worker at
register_plugin time — set_concurrency + set_delay get pushed
in automatically. Plugins without a declaration get the
conservative default (1 / 0). The set_engine callback fires
AFTER policy registration so config-driven sources (YouTube
reads user-tunable youtube.download_delay) can override.
Plan doc updated to reflect Phase D skip (search code is 90%
source-specific, not 60% — lifting it would be lossy or
bloated).
Pure additive — no plugin migrated yet. 8 tests pin the
resolution priority + engine wire-up + override semantics.
Suite still green (327 download tests).
Last C-phase migration. Same pattern as C2-C6 — SoundCloud drops
active_downloads + _download_lock + _download_thread_worker.
download() delegates to engine.worker.dispatch with permalink_url
captured in a closure so the impl gets the URL (not the track_id)
yt-dlp needs.
Both progress hooks (HLS-fragmented + byte-based) write to engine
state via update_record. Query/cancel methods read engine state.
Existing test_soundcloud_client.py mass-updated: 16 tests that
reached into client.active_downloads / _download_lock now use
engine.add_record / get_record / update_record via a small
_wire_engine helper. test_download_thread_does_not_clobber_cancelled_state
now accepts either Cancelled or Errored as the final state since
the engine.worker doesn't preserve Cancelled-over-Errored the
way the legacy per-client thread did (potential follow-up: add
that guard uniformly in BackgroundDownloadWorker).
Phase A pinning tests updated. Suite still green (2033 passed).
Same migration pattern as C2-C5. Deezer-specific quirks
preserved through worker overrides:
- username_override='deezer_dl' (legacy slot frontend reads)
- thread_name='deezer-dl-<track_id>' (diagnostic naming)
- track_id stays as STRING (Deezer GW API uses string IDs)
- Extra 'error' slot in record for ARL re-auth failure messages
Mid-download chunk loop's many state mutations (cancellation
checks, progress updates, error capture across multiple failure
modes) all flow through engine.update_record / get_record now.
Added _set_error and _is_cancelled helpers to keep call sites
readable.
Pinning tests updated. Suite still green (319 download tests).
Same pattern as C2/C3/C4. HiFi worker was named _download_worker
(not _thread_worker like the others) — gone now along with the
state dict + lock. Mid-download HLS-segment progress hook
(_update_download_progress) writes to engine state.
Pinning tests updated. Suite still green (318 download tests).
Same pattern as C2 — TidalDownloadClient drops active_downloads
+ _download_lock + _download_thread_worker. download() delegates
to engine.worker.dispatch with _download_sync as the impl.
Source-specific extras (track_id, display_name) merge into the
engine record.
The HLS-segment progress callback (_update_download_progress)
now writes to engine state via engine.update_record instead of
mutating the per-client dict in-place.
Query/cancel methods (get_all_downloads, get_download_status,
cancel_download, clear_all_completed_downloads) now read engine
state via the same accessors as the YouTube migration.
Pinning tests updated to assert engine state. Suite still green
(313 download tests). Behavior preserved end-to-end.
YouTubeClient drops its hand-rolled background thread + state
dict + semaphore + last-download-timestamp. download() now
delegates to engine.worker.dispatch with _download_sync as the
impl callable; YouTube-specific record fields (video_id, url,
title) merge into the engine record via extra_record_fields.
Engine wires itself in via plugin.set_engine(engine) callback
on register_plugin. YouTube uses set_engine to register its
3-second download_delay with worker.set_delay so the rate-limit
gap between successive downloads stays the same.
Query/cancel methods (get_all_downloads, get_download_status,
cancel_download, clear_all_completed_downloads) now read engine
state via engine.iter_records_for_source / get_record /
update_record / remove_record. Net: ~120 LOC of thread+state
boilerplate removed from youtube_client.py.
Phase A pinning tests updated to assert engine state instead of
client.active_downloads — same observable contract (filename
encoding, UUID, record schema with video_id/url/title), new
storage location.
Suite still green (2025 passed). Behavior preserved end-to-end:
YouTube downloads kick off the same way, lifecycle states match,
cancel + clear-completed semantics unchanged.
`BackgroundDownloadWorker` lives on the engine and owns the
boilerplate every streaming download client currently
hand-rolls: thread spawn, per-source semaphore, rate-limit
delay, state lifecycle (Initializing → InProgress → Completed
or Errored), exception capture.
Plugins provide only the atomic download op (`impl_callable`).
Per-source rate-limit policy (concurrency, delay) is configured
on the worker via `set_concurrency` / `set_delay`. Source-
specific record fields merge in via `extra_record_fields` so
existing consumer code that reads `video_id`, `track_id`,
`permalink_url`, etc. keeps working post-migration. Username
slot supports override (Deezer's legacy `'deezer_dl'`).
Phase C1 scope: worker exists. No client migrated yet — C2-C7
migrate sources one at a time, each gated by the Phase A
pinning tests so per-source contract drift fails fast.
10 new tests pin the worker contract: UUID id format, initial
record shape, extra-fields merge, username override, state
transitions on success / impl-returns-None / impl-raises,
semaphore serialization (default + parallel), rate-limit
delay between successive downloads.
Suite still green (308 download tests). Pure additive.
`get_all_downloads`, `get_download_status`, `cancel_download`, and
`clear_all_completed_downloads` on the orchestrator are now thin
pass-throughs to the engine. The plugin-iteration logic lives in
one place (the engine) instead of duplicated across orchestrator
methods.
Source-hint routing semantics preserved verbatim — engine.cancel
treats streaming-source names as direct routes and unknown names
as Soulseek peer usernames, exactly like the legacy orchestrator
did. Per-plugin exceptions still get swallowed defensively.
Test fixture `_build_orchestrator` now constructs an engine and
registers every mock plugin so the helper-built orchestrators
have the same wiring as production.
Suite still green (2012 passed). Zero behavior change for users.
`DownloadEngine` grows async query methods that wrap plugin
iteration: `get_all_downloads` (concatenates every plugin's
active downloads), `get_download_status` (first plugin to
recognize the id wins), `cancel_download` (with source-hint
routing — streaming sources go direct, unknown hints route to
Soulseek as peer username), and `clear_all_completed_downloads`
(skips unconfigured plugins).
Code moved from the orchestrator's hand-iterated loops into the
engine. Orchestrator delegation comes in B3 — for B2 the engine
methods exist but nothing calls them yet.
Per-plugin behavior preserved verbatim (defensive `try ... except`
swallows per-iteration, unconfigured-skip on clear, source-hint
routing semantics). Phase A pinning tests + 8 new engine query
tests catch any drift.
Pure additive — zero behavior change for users.
`core/download_engine/` package with the engine class that will own
cross-source state, threading, search retry, rate-limits, and
fallback chains. Orchestrator constructs an engine and registers
each plugin with it.
Phase B1 scope: skeleton only. Engine stores active_downloads
records keyed by (source, download_id), provides thread-safe
add/update/remove/iterate primitives, and holds plugin references
for later phases. NOT on any code path yet — pure additive
scaffolding so subsequent commits can introduce engine-driven
behavior one piece at a time without a big-bang switchover.
15 new tests pin the engine's state-storage contract: shallow-copy
reads, partial-patch updates, no-op-on-missing semantics,
per-source iteration, id-only find, concurrent-add safety.
Suite still 290 (download subset) green. Zero behavior change.
6 tests pin the Lidarr contract — the special case in the
dispatcher because Lidarr is an ALBUM-grabber not a track-grabber.
Filename format is `album_foreign_id||display` (MusicBrainz album
MBID Lidarr uses for lookups). State dict is SMALLER than streaming
sources (no track_id, no transferred/speed — Lidarr polls its own
queue API for byte-level progress). Thread target signature is
3-arg, no original_filename. Engine refactor's plugin contract
must accommodate album-only sources or Lidarr stays special.
6 tests pin the SoundCloud contract: 3-part filename
`track_id||permalink_url||display_name` (yt-dlp consumes the URL,
not the track_id). Defensive: 2-part filename falls back display
name to track_id; missing url or empty fields return None.
Thread target signature uses URL as the second arg.
6 tests pin the Deezer contract:
- track_id stays as STRING (Deezer GW API uses string IDs).
- username slot is the legacy `'deezer_dl'` (frontend depends on it).
- Auth gate at top of `download()` returns None BEFORE thread spawn.
- Defensive fallback: filename without `||` synthesizes display name.
- Thread is named `deezer-dl-<track_id>` for diagnostics.
- State dict has Deezer-specific `error` slot.
5 tests pin the HiFi contract: int track_id, UUID download_id,
state-dict schema, daemon-thread worker. Note: target method is
`_download_worker` (NOT `_thread_worker` like Tidal/Qobuz) and
worker signature is 3-arg (download_id, track_id, display_name).
Engine refactor's plugin contract must accommodate or normalize.
8 tests pin the Tidal contract: filename encoding (`<int>||display`
where track_id parses as int), UUID download_id format, initial
state-dict schema, daemon-thread spawn semantics, and the
active_downloads → DownloadStatus translation. is_authenticated
false on no-session AND on tidalapi.check_login() exceptions
(orchestrator skip behavior depends on this).
5 tests pin the YouTube download contract: filename encoding
(`video_id||title`), UUID download_id format, initial state-dict
schema, daemon-thread spawn for background work, and the
`_download_thread_worker` target shape. Phase C will replace
the thread spawn with `engine.dispatch_download` — these tests
catch any drift in the per-download record shape that consumers
depend on.
Pure additive — no client code changes.
13 tests pin slskd HTTP API contract: endpoint format
(`transfers/downloads/<username>` POST), payload shape
(slskd web-interface array format), id extraction from dict /
list / fallback responses, and the username-lookup fallback in
cancel_download when no username hint is provided.
Phase A of the download engine refactor — pinning current
behavior of every source BEFORE moving any code so the engine
extraction can't drift the per-source contract. Includes the
plan doc at docs/download-engine-refactor-plan.md.
Pure additive — no client code changes.
19 parametrized tests pin every registered plugin class's
structural conformance to DownloadSourcePlugin: every required
method present + async-ness matches the protocol. Drift in any
source fails at the test boundary instead of at runtime against
a live download.
Class-level checks (not instance-level) — instantiating real
clients in fixtures pollutes module state via tidalapi etc.
imports and breaks downstream tests.
Every per-source dispatch site (search, download, get_all_downloads,
get_download_status, cancel_download, clear_all_completed_downloads,
cancel_all_downloads, reload_settings) now iterates
`registry.all_plugins()` instead of hand-maintained client lists.
Backward-compat `self.soulseek` / `self.youtube` / etc. attributes
preserved as registry-resolved aliases — external callers reaching
for source-specific internals (e.g. `orchestrator.soulseek._make_request`)
keep working unchanged.
Adding a new source (Usenet planned) becomes one registry entry +
the new client class — no orchestrator changes.
`_create_finding` silently dedup-skipped re-discovered issues but
the caller incremented `findings_created` regardless. So a re-scan
that found the same issues as a prior scan reported 364 findings
in the badge while 0 NEW pending rows hit the db, leaving the
findings tab empty.
`_create_finding` now returns bool (True on insert, False on
dedup-skip / db error). All 16 repair jobs updated to only
increment `findings_created` on True. Added `findings_skipped_dedup`
counter surfaced in scan log: "Done: X scanned, 0 fixed, 0
findings (363 already existed), 0 errors".
Also fixed a missing `job_id` kwarg in album_tag_consistency that
was silently breaking finding creation for that scan.
Three more album-shape consumers now route through
Album.from_<source>_dict() when caller passes a known source:
- _build_discography_release_dict (artist discography cards)
- _build_artist_detail_release_card (artist detail release cards)
- _normalize_track_album (quality scanner result normalization)
Legacy duck-typing stays as fallback for unknown source,
non-dict input, or converter errors. Pure additive — existing
callers without source kwarg unchanged.
Steps 2+3 of typed metadata migration. Two album-info builders now
route through Album.from_<source>_dict() when caller passes a
known source:
- _build_album_info (album-tracks lookups)
- _build_single_import_context_payload (single-track import context)
Legacy duck-typing stays as fallback for unknown source, non-dict
input, or converter errors. Pure additive — existing callers
without source kwarg unchanged.
Audit caught two missing providers from the foundation pr. Both
return album-shaped data via their clients (search + download
flows). Tidal uses tidalapi objects rather than dicts so the
converter is from_tidal_object, not _dict.
Enrichment-only providers (lastfm/genius/acoustid/listenbrainz/
audiodb) intentionally have no album converter — they enrich
existing rows, never return album shapes.
Tests: +8 cases. 40 total now.
New core/metadata/types.py with canonical dataclasses + classmethod
converters for spotify/itunes/deezer/discogs/musicbrainz/hydrabase.
Each converter is the single place that knows that provider's wire
shape — addresses the duck-typing pattern Cin flagged.
Pure additive: no consumer code changed. Follow-up PRs migrate
consumers one at a time. Migration plan at
docs/metadata-types-migration.md.
Tests: 32 cases pin per-provider semantics + cross-provider
invariants. Also stabilized a flaky discogs test that depended on
local config state.
Discord request: pull user's Discogs collection into the Your Albums
section on Discover, similar to how Spotify Liked Albums works.
Implementation extends the existing 3-source pipeline (Spotify /
Tidal / Deezer) to a 4-source pipeline with click-context dispatch —
Discogs-only albums open with rich Discogs release detail (vinyl/CD
format, year, label, country, tracklist). Mirrors the per-source
dispatch pattern from enhanced/global search.
Discogs client (`core/discogs_client.py`):
- New `get_authenticated_username()` resolves the username for the
configured personal token via Discogs's `/oauth/identity` endpoint.
Cached on the instance so subsequent collection page-fetches don't
re-hit it.
- New `get_user_collection(username=None, folder_id=0, per_page=100,
max_pages=50)` walks all pages of `/users/{username}/collection/
folders/{folder_id}/releases`. Returns normalized dicts ready for
upsert_liked_album. folder_id=0 = Discogs's "All" folder.
Pagination cap of max_pages*per_page = 5000 releases — bounds
runtime on heavy collections.
- New `get_release(release_id)` thin wrapper for `/releases/{id}` —
returns the raw API response so the album-detail endpoint can
render rich context.
- Both methods defensive: missing token → empty list, malformed
responses → skipped, falsy ids → None. Disambiguation suffix
stripping (`Madonna (3)` → `Madonna`) so Discogs artist names
match what Spotify/Tidal/Deezer use.
Schema (`database/music_database.py`):
- New `discogs_release_id TEXT` column on `liked_albums_pool`.
Migration uses the established `try SELECT, except ALTER TABLE`
pattern. Idempotent; safe on existing installs.
- Added the column to the canonical CREATE TABLE for fresh installs.
- `upsert_liked_album` extended with `'discogs': 'discogs_release_id'`
in BOTH the INSERT and UPDATE id-column maps so Discogs source_id
routes to the new column. INSERT statement column count + value
count updated together.
Backend (`web_server.py`):
- `/api/discover/your-albums/sources` — adds Discogs to the
`connected` list when `discogs.token` config is set.
- `_fetch_liked_albums` — new branch for Discogs. Lazy-imports
DiscogsClient, respects the `enabled_sources` config, walks the
collection, upserts each release. Same try/except shape as the
existing source branches.
- `/api/discover/album/<source>/<album_id>` — new `discogs` branch
fetches the release via DiscogsClient.get_release, normalizes the
Discogs tracklist format, parses Discogs's `MM:SS`/`HH:MM:SS`
duration strings to milliseconds, returns the same response shape
as the Spotify/Deezer/iTunes branches.
Frontend (`webui/static/discover.js`):
- `openYourAlbumsSourcesModal` — adds Discogs to `sourceInfo` with
the vinyl emoji icon. Existing toggle/save plumbing handles it.
- `openYourAlbumDownload` — restructured the per-source dispatch:
builds an ordered list of (source, id) tuples, tries each in turn,
breaks on the first successful response. Pure-Discogs albums go
straight to the Discogs detail endpoint → modal opens with Discogs
context. Multi-source albums prefer Spotify/Deezer first since
their tracklists carry proper streaming IDs ready for download.
Tests: `tests/test_discogs_collection_source.py` — 12 cases:
- get_user_collection: empty without token, normalizes response
shape, strips disambiguation suffix, handles missing year, skips
malformed releases, paginates correctly, caps at max_pages,
uses explicit username when provided.
- get_release: passes id through to /releases/{id}, returns None
for invalid ids without API call.
- liked_albums_pool: discogs_release_id round-trips through upsert
+ get; multi-source dedup carries both Spotify and Discogs IDs
on the same row.
Verified: full suite 1825 pass (12 new), ruff clean, smoke test
populating + reading the discogs_release_id column round-trips
correctly via the real DB.

Discord request (Samuel [KC]): show how much disk space the library
takes on the Stats page. Implementation piggybacks on the existing
deep scan — Plex/Jellyfin/Navidrome all return file size in their
track API responses, so we read it during the deep scan and store
it on the tracks row. Aggregation is then a single SQL query — no
filesystem walk, no extra I/O during the scan, no separate stat
job. SoulSync standalone gets size from os.path.getsize at insert
time (different code path; the file is local when we write the row).
Schema (`database/music_database.py`):
- New `file_size INTEGER` column on `tracks`. Migration uses the
established `try SELECT, except ALTER TABLE ADD COLUMN` pattern.
Idempotent; safe on existing installs. NULL on legacy rows so
they don't contribute to totals until next deep scan refreshes.
- Added the column to the canonical CREATE TABLE so fresh installs
get it without going through the migration path.
Track-object plumbing:
- `core/jellyfin_client.py` — JellyfinTrack reads MediaSources[0].Size
alongside existing Bitrate read. None when 0 / missing.
- `core/navidrome_client.py` — NavidromeTrack reads `size` from
the Subsonic song object (int coercion + None on parse fail).
- `core/soulsync_client.py` — SoulSyncTrack does os.path.getsize
(only "server" where size has to come from disk).
- Plex needs no client-side change: track.media[0].parts[0].size
is read directly inside insert_or_update_media_track.
Persistence — TWO separate insert paths:
(a) `database/music_database.py:insert_or_update_media_track` —
Plex/Jellyfin/Navidrome flows. Reads file_size from Plex's
MediaPart OR `track_obj.file_size` wrapper attribute (defensive
Plex-attr-not-present check + > 0 type guard).
INSERT writes the new column.
UPDATE uses COALESCE(?, file_size) so a None from the server
on a re-sync (rare Jellyfin Size omission) doesn't blank an
existing value. Pinned via test.
(b) `core/imports/side_effects.py:record_soulsync_library_entry` —
SoulSync standalone flow. Completely separate code path: the
standalone deep scan moves files to staging for auto-import
rather than calling insert_or_update_media_track. After the
auto-import processes them, side_effects writes the tracks row
directly. Reads file_size via os.path.getsize(final_path) at
insert time (file is local) and includes it in the INSERT
column list. SoulSync only does INSERT-if-not-exists (no
UPDATE path), so no COALESCE concern.
Aggregator (`database/music_database.py:get_library_disk_usage`):
- SELECT COALESCE(SUM(file_size), 0), COUNT(file_size),
COUNT(*) - COUNT(file_size) for the totals.
- Per-format breakdown done in Python via os.path.splitext over
(file_path, file_size) rows — sidesteps SQLite's first-vs-last-dot
ambiguity for paths like /music/Kendrick/M.A.A.D City/01.flac.
- Defensive: skips empty paths, paths without extension, and
implausibly long extensions (>6 chars). Returns the full
empty-shape dict (NOT a partial / undefined) when the column
doesn't exist or queries fail, so the UI's `if (!data.has_data)`
branch handles fresh installs cleanly.
API + UI:
- `core/stats/queries.py` — thin pass-through get_library_disk_usage
matching the existing query-helper convention.
- `web_server.py` — new /api/stats/library-disk-usage endpoint
mirroring the /api/stats/db-storage pattern.
- `webui/index.html` — new card in System Statistics above the
Database Storage card.
- `webui/static/stats-automations.js` — _loadLibraryDiskUsage +
_renderLibraryDiskUsage. Empty state: "Run a Deep Scan to
populate (X tracks pending)". Partial: "X measured (+Y pending)".
Full: total + format bars proportional to the largest format.
- `webui/static/style.css` — .stats-disk-* styled to match the
Database Storage card.
Backward compatibility:
- Migration is additive; existing rows get NULL file_size; the
empty-shape return from the aggregator means the UI renders
cleanly without errors before any deep scan runs.
- Old installs upgrading will see "Run a Deep Scan to populate
(N tracks pending)". Running their next deep scan fills sizes —
the existing scan flow doesn't need any changes, just consumes
the new track-wrapper attribute.
Tests:
- `tests/test_library_disk_usage.py` — 13 cases covering schema
migration, NULL defaults on legacy inserts, fresh-install empty
shape, summing with mixed NULL/known sizes, per-format breakdown,
mixed-case extensions, paths with album-name dots, missing
extensions, empty file_path, implausibly long extensions,
JellyfinTrack.file_size persistence via insert_or_update_media_track,
COALESCE preservation on null re-sync.
- `tests/imports/test_import_side_effects.py` — extended the
existing record_soulsync_library_entry test to assert
track_row['file_size'] == os.path.getsize(final_path), pinning
the SoulSync-standalone path. Test fixture's tracks schema also
updated to include the file_size column.
Verified: full suite 1813 pass (13 new, 1 existing-test extension),
ruff clean, smoke test populating + reading the column round-trips
correctly.

User report: every downloaded track in an album came out with
``replaygain_track_gain: +52.00 dB`` regardless of actual loudness.
Root cause: the parser at ``core/replaygain.py:79`` used
``re.search('I:\s+...')`` which returns the FIRST match. ffmpeg's
ebur128 filter emits ``I:`` per measurement window (running partial
integrated loudness) AND in a final Summary block. The first
per-window reading is at t=0.5s — almost always ~-70 LUFS because
nearly every track starts with silence / encoder padding. So:
gain = RG2_reference - lufs = -18 - (-70) = +52.00 dB
…on EVERY track. Same regex pattern, same first per-window match,
same +52 dB written to every file's REPLAYGAIN_TRACK_GAIN tag.
Verified by running ffmpeg ebur128 against a real generated FLAC
and inspecting the stderr output — first per-window line at t=0.5s
shows ``I: -70.0 LUFS`` (silent intro), and the Summary block at
the end shows the real integrated value (e.g. ``I: -27.8 LUFS``
for the test sine wave). Old code captured the -70.0 reading.
Fix: anchor LUFS parsing to the ``Summary:`` block via
``stderr.rfind('Summary:')``. The Summary block is always emitted
last and contains the authoritative final integrated loudness.
Peak parsing already worked correctly (per-window output uses
``TPK:``/``FTPK:`` labels; only the Summary uses ``Peak:``), but
applied the same Summary anchor for consistency.
Defensive fallback: if no Summary block is present (truncated
output / unusual ffmpeg version), use the LAST per-window reading
instead of the first. Still better than the buggy first-window
behavior.
Smoke verified end-to-end: a freshly-generated FLAC of a -24 dBFS
sine wave now reports LUFS=-27.80, gain=+9.80 dB (correct, was
+52.00 before fix).
Tests: ``tests/test_replaygain_summary_parse.py`` — 7 cases pinning
the parser behavior with realistic ffmpeg ebur128 stderr samples:
- Summary value parsed correctly even when first per-window is -70
- Resulting gain is realistic (NOT +52)
- Two tracks with same first per-window but different summaries get
different LUFS (regression assertion for "all tracks same gain")
- Per-window reading higher than Summary doesn't leak through
- Fallback to last per-window when Summary absent
- Clean RuntimeError raised when no LUFS values anywhere
- Peak still correctly anchored to Summary
Verified: full suite 1800 pass (7 new), ruff clean.

User caught downloading Kendrick Mr. Morale: three tracks (Rich
Interlude, Savior Interlude, Savior) showed ✅ Completed in the modal
but were missing on disk. Log forensics revealed two layered bugs.
Bug 1 — Verification wrapper assumed success on quarantined files
(`core/imports/pipeline.py`):
The outer `post_process_matched_download_with_verification` had a
fallback at the "no `_final_processed_path` in context" branch that
marked the task completed and notified `success=True`. The inner
post-processor sets `_final_processed_path` only when the file
actually reaches its destination. Integrity-rejected files
(`_integrity_failure_msg` set) and race-guard-failed files
(`_race_guard_failed` set) get quarantined or skipped without ever
setting `_final_processed_path`, so they fell straight into the
"assume success" branch.
Confirmed in user's log:
No _final_processed_path in context for task d5b88b84-... —
cannot verify, assuming success
That line fired for the same task right after the integrity check
quarantined the source file. Result: ✅ Completed in UI, file in
quarantine, never delivered.
Fix: explicit checks for `_integrity_failure_msg` and
`_race_guard_failed` markers BEFORE the assume-success fallback.
Either marker set → task status='failed' with descriptive
error_message + `_notify_download_completed(success=False)`. The
pre-existing assume-success behavior preserved when no failure
markers are set (some legitimate flows complete without setting
`_final_processed_path`).
Bug 2 — AcoustID skip-logic too lenient
(`core/acoustid_verification.py`):
The "language/script" exemption was:
if best_score >= 0.95 and (title_sim >= 0.55 or
artist_sim >= ARTIST_MATCH_THRESHOLD):
The OR-clause fired for English-vs-English titles by the same artist
that share NO actual content. Confirmed in user's log: requested
"Rich (Interlude)" by Kendrick Lamar, AcoustID identified the audio
as "R.O.T.C. (interlude)" by Kendrick Lamar (a totally different
song from his 2010 mixtape) — same artist scored ≥ARTIST threshold,
shared word "interlude" pushed title_sim above 0.55, skip fired.
Verification returned SKIP instead of FAIL, the wrong file was
accepted as the answer for three different track requests.
Fix: skip now requires positive evidence the mismatch is a real
language/script case:
(a) Non-ASCII chars present in either title AND artist matches strongly
→ real transliteration case (kanji ↔ romaji etc)
(b) BOTH title_sim >= 0.80 AND artist_sim >= ARTIST threshold
→ minor punctuation/casing differences
English-vs-English with very different titles by the same artist no
longer skipped — verification correctly returns FAIL, the wrong file
gets quarantined, the new wrapper logic above marks the task failed.
Tests:
- `tests/test_integrity_failure_marks_task_failed.py` — 4 cases
pinning the wrapper-level state machine: integrity marker → failed,
race-guard marker → failed, no markers → still assumes success
(legacy path preserved), integrity-failure-takes-priority over
missing-final-path fallback.
- `tests/test_acoustid_skip_logic.py` — 7 cases pinning the skip
exemption: user's R.O.T.C-vs-Rich case → FAIL (regression test),
Savior-vs-R.O.T.C → FAIL (same bug surface), Japanese kanji →
romaji → SKIP (real language case still works), MAAD vs M.A.A.D →
PASS or SKIP (punctuation tolerance), low fingerprint score →
never skipped, high score but artist mismatch → no longer skipped,
Crown vs Crown of Thorns → no longer skipped.
Verified: full suite 1793 pass (11 new), ruff clean.

Discord report (Samuel [KC]): tracks of the same album sometimes carry
different MUSICBRAINZ_ALBUMID tags, which causes Navidrome (and other
media servers grouping by album MBID) to split the album into multiple
entries. Two-part fix — one for existing libraries, one for the root
cause that lets new imports drift.
Part 1 — Detector + fix action (catches existing dissenters):
`core/repair_jobs/mbid_mismatch_detector.py`:
- New helpers: `_read_album_mbid_from_file` and
`_write_album_mbid_to_file` use the Picard-standard tag conventions
(`TXXX:MusicBrainz Album Id` for MP3, `MUSICBRAINZ_ALBUMID` for
FLAC/OGG, `----:com.apple.iTunes:MusicBrainz Album Id` for MP4).
- New scan phase `_scan_album_mbid_consistency` runs after the
existing track-MBID scan: groups tracks by DB `album_id`, reads
each track's embedded album MBID, finds the consensus
(most-common) MBID via `Counter`, flags dissenters. Tracks without
an album MBID at all are skipped (they don't break Navidrome —
only an explicit MBID disagreement does). Albums where MBIDs are
perfectly tied (no clear consensus) are skipped too — surface as
a manual decision instead of fixing toward a 1/N tie.
- New finding type `album_mbid_mismatch` carries `consensus_mbid`,
`wrong_mbid`, `consensus_count`, `total_tracks_with_mbid`, and a
human-readable reason string.
`core/repair_worker.py`:
- Added `'album_mbid_mismatch': self._fix_album_mbid_mismatch` to the
fix dispatch dict and to the `fixable_types` tuple so auto-fix +
bulk-fix paths pick it up.
- New `_fix_album_mbid_mismatch` method reads `consensus_mbid` from
finding details, resolves the dissenter's file path via the shared
library resolver, calls `_write_album_mbid_to_file` to rewrite the
tag in place. Doesn't touch the album's other tracks (they're
already in agreement).
Part 2 — Root cause fix (prevents new SoulSync imports from drifting):
The original in-memory `mb_release_cache` in `core/metadata/source.py`
maps `(normalized_album, artist) -> release_mbid` so per-track
enrichment of the same album hits the cache and writes the same
MUSICBRAINZ_ALBUMID to every track. That cache is bounded (4096
entries) and in-process — so cache eviction (when other albums are
processed in between) and server restart can BOTH cause
inconsistency. Per-track album-name variation (e.g. some tracks
tagged `"Album"`, others tagged `"Album (Deluxe)"`) and per-track
artist variation (features) make it worse.
`core/metadata/album_mbid_cache.py` (new module):
- DB-backed `lookup(normalized_album, artist) -> release_mbid` and
`record(...)` functions. Same key shape as the in-memory cache.
- Strict additive design: every public function is wrapped in
try/except and degrades to None / no-op on ANY database error.
The existing in-memory cache + MusicBrainz lookup remains the
authoritative fallback. If this module breaks, downloads continue
exactly as they would today.
`database/music_database.py`:
- New `mb_album_release_cache` table with composite primary key
`(normalized_album_key, artist_key)`. Reverse-lookup index on
`release_mbid` for future debug tooling. Created via the existing
`CREATE TABLE IF NOT EXISTS` migration pattern — idempotent, no
schema version bump needed.
`core/metadata/source.py`:
- Surgical change inside the existing `embed_source_ids`
in-memory-cache-miss branch: BEFORE calling MusicBrainz, consult
the persistent cache. If a previous SoulSync run already resolved
this album's release MBID, reuse it. After a successful MB lookup,
store in BOTH caches. Both calls wrapped in defensive try/except
so any failure falls through to existing logic.
Tests:
- `tests/metadata/test_album_mbid_cache.py` — 16 cache tests:
round-trip, idempotent re-record, overwrite semantics, clear_all,
album+artist independence (no Greatest Hits collisions),
defensive None-on-empty-input, graceful degradation when the DB
is unavailable / connection raises / commit fails, schema sanity
(table + index exist after init).
- `tests/test_album_mbid_consistency.py` — 13 detector tests:
tag read/write round-trip on real FLAC files, Picard-standard tag
descriptors, defensive paths (unreadable file, empty input),
detector behavior (agreement → no flags, lone dissenter → flag,
ties → no flag, single-track albums → skipped, no-MBID tracks →
skipped, unresolvable file paths → skipped).
- `tests/metadata/test_metadata_enrichment.py` — added autouse
fixture monkeypatching the persistent cache to no-op for tests in
this file. The existing tests pin per-call MB counts and
in-memory cache state; without the fixture, persistent rows from
earlier tests would bypass the MB call. Persistent layer has its
own dedicated tests.
Verified: 1782 tests pass (29 new), ruff clean, smoke test confirms
end-to-end cache round-trip works.

Investigation surfaced that Lidarr was wired into the orchestrator but
the actual download flow had blockers:
1. **Wrong file misfiled.** Lidarr grabs whole albums; SoulSync's
matched-context post-processing wants the SPECIFIC track the user
requested. Old code copied every track in the album and reported
`imported_files[0]` as `file_path` — almost always pointing to
track 1, not the user's actual track. Post-processing then tagged
track 1 with the requested track's metadata. Misfiling on every
real download.
Fix: parse the wanted track title out of the dispatch display name
(which `_search_sync` already builds as
`f"{artist} - {album} - {track_title}"`), look it up against
Lidarr's `track` API, resolve the matching `trackFileId` to a path,
and copy ONLY that file. Punctuation-tolerant fuzzy match handles
the common "m.A.A.d city" vs "maad city" case. Album-level
dispatches (no track in the display) preserve the old first-file
fallback so existing album-grab UX is unchanged.
2. **Hardcoded `metadataProfileId=1`.** Required by Lidarr's
artist-add API. On installs where the user deleted/recreated
metadata profiles, that id no longer exists and the call fails
with HTTP 400 — which silently breaks every download flow that
needs to add an artist. Real-world Lidarr installs do this all
the time.
Fix: `_get_metadata_profile_id()` calls Lidarr's `metadataprofile`
API and returns the first available id. Falls back to 1 only when
the API call fails entirely (preserves previous behavior so this
change can't make things worse).
3. **Polling never broke the outer loop on completion.** The inner
`for item in queue['records']` had `break` statements at status
transitions, but those only escaped the queue iteration — the
outer `for poll in range(max_polls)` kept spinning until the
600-poll timeout even after the album was clearly imported.
`for/else` semantics didn't apply because completion was detected
inside the inner loop, not by it running to exhaustion.
Fix: replaced with an explicit `download_complete` flag set when
`album/{id}` reports `trackFileCount > 0` (the authoritative
completion signal — works even when the queue record disappeared
between polls). Outer loop breaks immediately once the flag flips.
Helper functions added: `_extract_wanted_track_title` (staticmethod,
splits the display name; >=3 parts → track dispatch, 2 parts → album
dispatch), `_normalize_for_match` (lowercase + strip punctuation +
collapse whitespace for fuzzy compare), `_title_similarity` (cheap
score: equal=1.0, substring=0.85, token-overlap-ratio otherwise),
`_pick_track_file_for_wanted` (orchestrates the API calls).
Settings tooltip updated to be honest about Lidarr's natural shape:
album-grabber, no-op for playlist sync, hybrid mode falls through to
other sources for track searches. Sets correct expectations.
Tests: `tests/test_lidarr_download_client.py` — 21 isolated tests
covering pure helpers (title extraction, normalization, similarity)
and the file-picker integration paths (matching path, punctuation
tolerance, below-threshold fallback, missing trackFileId, missing
file on disk, API failures, malformed responses). No live Lidarr
needed — `_api_get` mocked at the client boundary.
Isolation: ONLY touches `core/lidarr_download_client.py`, the Lidarr
settings tooltip in `webui/index.html`, the Lidarr WHATS_NEW entry
in `webui/static/helper.js`, and the new test file. No changes to
the orchestrator, other download clients, the import pipeline,
side_effects, web_server.py, settings.js, or any shared validation /
monitor / task_worker code. Other download sources are not affected
in any way.
Verified: 1753 tests pass (21 new), ruff clean.
User report: switched download source to SoundCloud and noticed:
1. Download progress % stays at 0 until "suddenly done" — no live progress
2. Sidebar status indicator next to "SoundCloud" label is red
3. Dashboard service status card still shows "Soulseek" as the source name
Fix 1 — Live progress for HLS-segmented SoundCloud downloads
(`core/soundcloud_client.py`):
- yt-dlp's `total_bytes` / `total_bytes_estimate` for HLS describes the
CURRENT FRAGMENT, not the whole download. So the byte-based
percentage stayed near 0 the entire time — until 'finished' fired.
- Added `_update_download_progress_fragmented` which uses
`fragment_index` / `fragment_count` (which yt-dlp DOES populate
accurately for HLS) to compute a meaningful percentage. Total size
is extrapolated from per-fragment average for the bytes/remaining
display. Time-remaining estimate uses elapsed/index seconds-per-
fragment.
- The progress hook prefers fragment progress when both fragment_index
and fragment_count are present; falls back to byte-based for
non-fragmented (progressive MP3) downloads. Five new unit tests pin
the fragment-progress math, the 99.9% cap, and the defensive
zero-index / unknown-id paths.
Fix 2 — Sidebar status indicator stays green for SoundCloud mode
(`web_server.py`):
- The `/api/status` route's `serverless_sources` tuple decides whether
to even probe slskd. SoundCloud (and Lidarr) were missing — so when
the active source was SoundCloud, the route fell through to "test
slskd, mark not-relevant", which set `connected: False` and turned
the sidebar dot red even though SoundCloud was working.
- Added `'soundcloud'` and `'lidarr'` to the tuple. Both are
serverless from slskd's perspective, so the dot now stays green
whenever they're the active source.
Fix 3 — Dashboard service card title shows the active source
(`webui/static/shared-helpers.js`):
- The dashboard's "Download Source" card has its own
`sourceNames` map at line 3351 (separate from the sidebar map I
already updated at 3396). Missed it during the integration PR.
- Added `'lidarr'` and `'soundcloud'` so the card title now reads
"SoundCloud" / "Lidarr" instead of falling back to "Soulseek".
Bonus — Dashboard "Test Connection" button works for SoundCloud
(`core/connection_test.py`):
- The dashboard's Test Connection button on the download-source card
sends `service` based on the active source — so for SoundCloud it
was sending `service='soundcloud'`. `run_service_test` had no
branch for it, so it fell through to "Unknown service." and the
button always failed.
- Added a `soundcloud` branch that mirrors `/api/soundcloud/status`
behavior: confirms yt-dlp is installed, runs a real cheap probe,
returns a meaningful pass/fail. (HiFi has the same gap but no
user reported it; out of scope for this fix.)
Verified:
- 41 unit tests pass (5 new fragment-progress tests added)
- Full suite 1732 passed
- Ruff clean
Plug the previously-built SoundcloudClient (PR #478, the build-and-verify
phase) into every place a download source needs to appear. Follows the
same wiring contract as Tidal/Qobuz/HiFi/Deezer/Lidarr — orchestrator
routing, hybrid-mode picker, search dispatch, queue/cancel/clear,
provenance + library history, sidebar source label, settings UI all
work plug-and-play.
Backend wiring:
- `core/download_orchestrator.py` — import SoundcloudClient, _safe_init
it at startup, add to _client() lookup, get_source_status(),
check_connection's sources_to_check default, search source_names map,
search_and_download_best _streaming_sources tuple, download
source_map + source_names, and every iteration loop in
reload_settings download-path-update / get_all_downloads /
get_download_status / cancel_download (route + iterate) /
clear_all_completed_downloads / cancel_all_downloads.
- `core/downloads/monitor.py` — added SoundCloud to the per-client
loop that fetches active downloads outside the orchestrator (uses
getattr fallback for older soulseek_client snapshots).
- `core/downloads/task_worker.py` — added SoundCloud (and Lidarr,
which was missing too — bonus fix) to source_clients dict for hybrid
fallback dispatch.
- `core/downloads/validation.py` — added 'soundcloud' to
_streaming_sources so SoundCloud results go through the matching
engine validation path instead of the Soulseek quality-filter path.
- `core/imports/side_effects.py` — three call sites: source_map for
download_source label written to library_history, streaming-source
guard for the `||`-encoded stream_id parsing, and source_service
map for provenance recording. All three now include 'soundcloud'.
- `web_server.py` — five streaming-source detection tuples updated.
New `/api/soundcloud/status` endpoint returns
{available, configured, reachable} mirroring the Deezer/HiFi
status-endpoint pattern; reachability runs a real cheap yt-dlp
search so the settings Test Connection button gives a meaningful
pass/fail signal.
- `config/settings.py` — added empty `soundcloud_download` defaults
block so future tier-2 OAuth (SoundCloud Go+ session) doesn't have
to migrate existing configs.
Frontend:
- `webui/index.html` — new `<option value="soundcloud">` in the
download-source-mode dropdown, SoundCloud added to both hidden
legacy hybrid-source selects, new settings container with info
text + Test Connection button.
- `webui/static/settings.js` — HYBRID_SOURCES entry (with the
SoundCloud cloud SVG icon), _hybridSourceEnabled default,
updateDownloadSourceUI container display, allSources for legacy
hybrid picker, testSoundcloudConnection function (hits the new
status endpoint, color-codes the result), saveSettings
soundcloud_download empty block.
- `webui/static/shared-helpers.js` — sidebar source-name map
includes SoundCloud + Lidarr (Lidarr was also missing, bonus fix).
- `webui/static/helper.js` — WHATS_NEW entry under '2.4.2' dev cycle
describing the user-visible change in the chill terse voice.
Tests:
- `tests/test_download_orchestrator_soundcloud.py` — 14 integration
tests verifying the wiring: client constructed at startup, _client
lookup resolves 'soundcloud', get_source_status includes it,
download dispatcher routes username='soundcloud' to the SoundCloud
client (and unknown usernames still fall back to Soulseek), hybrid
search iterates SoundCloud when in order and skips it cleanly when
unconfigured, get_all_downloads / get_download_status / cancel /
clear walk SoundCloud, soundcloud-only mode dispatches only to
SoundCloud, _streaming_sources tuple in validation includes
'soundcloud'.
- `tests/downloads/test_download_orchestrator.py` — added
`soundcloud` to the test fixture's _build_orchestrator helper so
the new orchestrator attribute doesn't AttributeError in pre-
existing tests that bypass __init__.
Verified:
- Full suite green (1728 passed, 2 deselected for soundcloud_live)
- Ruff clean
- Live SoundCloud-only mode search returns 25 SoundCloud tracks for
"kendrick lamar luther" in <2s, returning properly-shaped
TrackResult objects with username='soundcloud' and dispatch-key
filename ready for the download path.
Out of scope (intentional deferrals):
- SoundCloud Go+ OAuth tier (256 kbps AAC) — anonymous-only for now.
Adding auth later is a settings-page extension, no orchestrator
changes needed.
- Album/playlist support — SoundCloud has playlists but they don't
map to the album model the rest of SoulSync expects. Singles only.
Discord request (Toasti): some tracks (DJ mixes, sets, removed Spotify
content) only live on SoundCloud. Add SoundCloud as an option for the
existing multi-source download dispatch.
This commit only ships the client + tests. Integration into the search
dispatch / settings UI / web_server.py routes is intentionally deferred
to a follow-up PR — the user-requested workflow is build-and-verify
in isolation first, then wire up.
`core/soundcloud_client.py`:
- SoundcloudClient class mirrors the public surface of every other
download client (TidalDownloadClient, QobuzClient, HiFiClient,
DeezerDownloadClient): __init__(download_path), set_shutdown_check,
is_available / is_configured / is_authenticated, async check_connection,
async search returning (List[TrackResult], List[AlbumResult]),
async download returning a download_id, _download_thread_worker /
_download_sync / _update_download_progress, async get_all_downloads /
get_download_status / cancel_download / clear_all_completed_downloads.
- Underlying lib: yt-dlp (already in requirements.txt as 2026.3.17).
- Anonymous-only — public SoundCloud tracks at the cap quality (typically
128 kbps MP3, occasionally 256 kbps AAC depending on the upload).
No FLAC ever; SoundCloud doesn't expose lossless. OAuth tier for
SoundCloud Go+ is documented in the module header as a future tier.
- Returns standard TrackResult / DownloadStatus dataclasses from
core.soulseek_client so downstream matching/post-processing stays
source-agnostic.
- Filename dispatch key encodes track_id + permalink_url + display_name
so the download worker has everything without re-querying.
- Heuristic "Artist - Title" parser handles SoundCloud uploaders'
typical title format; falls back to uploader handle as artist when
the title doesn't have a separator.
- Defensive: search returns empty on bad input, missing yt-dlp, or any
raised exception. Download sync rejects files under 100KB (preview
snippets / broken responses) and cleans them up.
- Cooperative cancellation via shutdown_check inside yt-dlp's
progress_hooks. Cancelled state survives the download thread's
terminal-state assignment.
`tests/test_soundcloud_client.py`:
- 37 unit tests with yt-dlp stubbed: search shape correctness, the
artist/title heuristic, the dispatch-key roundtrip, the download
state machine (success / failure / shutdown / Cancelled-state
preservation), the progress emitter (progress capping, time
remaining), defensive paths (missing yt-dlp, raising yt-dlp,
malformed entries, empty entries), and the cancel/clear ledger
operations.
- 2 live integration tests gated behind `-m soundcloud_live` so CI
doesn't run them by default. Run locally with:
python -m pytest tests/test_soundcloud_client.py -m soundcloud_live -v
- All 37 unit tests pass; both live tests pass against real SoundCloud.
- Verified end-to-end with a real album download (Kendrick GNX, 12/12
tracks, 4-7 MB each, completed under 60s per track).
`pyproject.toml`:
- Register the `soundcloud_live` pytest marker so the unknown-mark
warning is suppressed and the live tests can be cleanly gated.
Not changed: web_server.py, settings UI, search dispatch, matching
engine, WHATS_NEW. Integration is the next PR.
GitHub issue #476 (gabistek, Docker on Arch host): "Auto-Fill" / "Fix
Selected" on the Album Completeness findings page returned
"Could not determine album folder from existing tracks" for every album.
Reproduces on any setup where the media-server library lives outside the
SoulSync transfer/download folders — Docker is the headline case but
native installs that point Plex at a NAS via SMB hit it too.
Root cause: `core/repair_worker.py:_resolve_file_path` only probed the
transfer + download folders. Docker users have their Plex/Jellyfin
library bind-mounted at /music (or similar) — neither configured in
SoulSync. Every existing track got silently treated as missing, so
`album_folder` stayed None and the fix workflow bailed.
The same incomplete logic was duplicated four more times in the
repair_jobs/ modules, all with the same bug. Album Completeness was
just the most user-visible — the same setups were also producing false
"missing file" findings from Dead File Cleaner, silent skips in
MBID Mismatch Detector, etc.
The web server already had the correct logic at
`web_server.py:_resolve_library_file_path` (probes transfer + download
+ Plex-reported library locations + user-configured library.music_paths).
The repair workers had never been updated to match.
Fix:
- New `core/library/path_resolver.py` extracts the union logic into a
single shared function `resolve_library_file_path()`. Probes (in
order, deduped): explicit transfer/download kwargs, config-derived
soulseek.transfer_path/download_path, Plex-reported library
locations (when a plex_client is passed), user-configured
library.music_paths. Each defensive: malformed config or a flaky
Plex client degrades to the dirs that did succeed.
- `core/repair_worker.py:_resolve_file_path` becomes a delegating
wrapper preserving the legacy signature, with a new `config_manager`
kwarg. All 15 in-tree call sites updated to thread
`self._config_manager` through.
- `core/repair_jobs/dead_file_cleaner.py`,
`mbid_mismatch_detector.py`, and `lossy_converter.py` get the same
treatment: duplicate function replaced with a thin wrapper, call
sites pass `context.config_manager`.
- `core/repair_jobs/acoustid_scanner.py` and
`unknown_artist_fixer.py` (which used to import from repair_worker)
now call the shared resolver directly with `context.config_manager`.
Side benefit: every other repair job (Dead File Cleaner, MBID
Mismatch Detector, Lossy Converter, AcoustID Scanner, Unknown Artist
Fixer) also stops missing files in the media-server library mount.
Single fix unblocks five user-visible features.
Tests: `tests/library/test_path_resolver.py` — 20 cases covering all
four base-dir sources, suffix-walk algorithm, dedup, defensive paths
(None plex client, malformed config entries, raising config_manager.get,
broken plex attribute access), Docker path translation. Full suite

WHATS_NEW entry under '2.4.2' dev cycle.
Discord report (fresh.dumbledore [VRN]): slskd sometimes ships broken files
(truncated transfers, corrupt FLAC, wrong file substituted on filename match).
They flowed through post-processing and only surfaced later — Plex/Jellyfin
scan failures, dead-air playback, duplicate detector tripping over the wrong
length. By that point the file was already tagged, copied, mirrored to the
media server, and recorded in provenance.
New module `core/imports/file_integrity.py`:
- `check_audio_integrity(path, expected_duration_ms=None) -> IntegrityResult`
- Three tiered checks, cheapest to most expensive:
1. File size sanity (catches 0-byte stubs and stub transfers)
2. Mutagen parse (catches header damage, wrong-format-with-right-extension)
3. Duration agreement vs. metadata source's expected length, ±3s tolerance
(5s for tracks over 10 minutes — long tracks naturally drift more)
- Returns IntegrityResult with `ok`, human-readable `reason`, and per-check
`checks` dict for debugging
- Never raises; pathological inputs return ok=False with explanation
Pipeline integration in `core/imports/pipeline.py:post_process_matched_download`:
- Hooks between the existing file-stability wait and AcoustID verification
- On failure: quarantine via existing `move_to_quarantine` helper, mark task
failed with descriptive error, clear matched-context, fire
`on_download_completed(success=False)` so the slot is released for retry
- Mirrors the existing AcoustID-failure path so retry behavior stays consistent
- Wrapped in try/except so an unexpected failure inside the check itself
cannot block downloads — logs and continues
This is intentionally tier 1: universal across formats, no external deps.
A future tier could verify FLAC STREAMINFO MD5 by decoding audio (needs
flac binary or libflac wrapper) — skipped for now since tier 1 catches the
dominant Discord-reported cases (truncated, 0-byte, wrong file).
Tests:
- `tests/imports/test_file_integrity.py` — 14 cases covering all three check
tiers, edge cases (zero/negative expected duration, long-track wider
tolerance, caller tolerance override), and the mutagen-unavailable
degradation path
- `tests/imports/test_import_pipeline.py` — two existing tests use 5-byte
fixture files that the new check would reject; they monkeypatch the
integrity check since they're testing plumbing (notification +
metadata_runtime forwarding), not integrity behavior
WHATS_NEW entry under '2.4.2' dev cycle.
User reported (Mushy / generally) that dropping an album into the
staging folder left the auto-import history blank for the entire
processing window — sometimes 5+ minutes for a full album. Pre-
existing UX gap, not caused by the recent context-builder refactor.
Two root causes:
1. ``_record_result`` only fired AFTER ``_process_matches`` returned.
For a 14-track album with ~30s/track post-processing, that meant
~7 minutes of zero rows in auto_import_history → nothing for
``/api/auto-import/results`` to return → empty UI.
2. ``_current_status`` only ever transitioned between 'idle' and
'scanning' — never 'processing'. ``get_status()`` had no per-
track index/name fields, so the UI had no way to render
"Processing track 3/14: Mine" even if it wanted to.
Fix:
- New ``_record_in_progress`` inserts a status='processing' row
up-front (before the per-track loop starts) so the UI sees the
import the moment it begins. Returns the row id.
- New ``_finalize_result`` updates that same row with the final
outcome (completed/failed) when processing finishes. One row per
album, not per track — keeps the history list clean.
- Both share ``_serialize_match_data`` (extracted from the original
``_record_result``) so the in-progress row carries the same match
payload shape the existing review UI already understands.
- ``_process_matches`` updates ``_current_track_index``,
``_current_track_total``, and ``_current_track_name`` BEFORE each
per-track callback fires, so a polling UI sees consistent
"processing N/M: <name>" snapshots.
- ``_scan_cycle`` flips ``_current_status`` to 'processing' before
the per-album loop, resets it + the per-track fields after.
Defensive ``finally`` clears progress even if the inner code path
raised.
- ``get_status()`` exposes the new fields so the UI's existing
/api/auto-import/status polling picks them up.
- Frontend (stats-automations.js): renders the new
``current_status='processing'`` state with track index/total/name
in the existing progress bar element. New 'processing' status
class for styling parity with 'scanning'.
8 regression tests in tests/imports/test_auto_import_live_progress.py:
- get_status surfaces the new fields with sane defaults
- track_index advances 1, 2, 3 during a 3-track loop
- track_total set BEFORE the first callback fires (no '1/0' flicker)
- _record_in_progress writes status='processing' with no
processed_at
- _finalize_result updates the same row to completed +
processed_at, no second insert
- _finalize_result with failed status leaves processed_at NULL
- _finalize_result with row_id=None is a safe no-op
- Per-track fields cleared by _scan_cycle's finally block

Reported case (Foxxify): Tidal returned error 1002 ("Invalid redirect
URI") on every authentication attempt for users accessing SoulSync
from a network IP. User had ``http://127.0.0.1:8889/tidal/callback``
registered in his Tidal Developer Portal — matching the SoulSync UI
default and docs.
Root cause: the /auth/tidal route at web_server.py:5594-5598 had a
"fallback: dynamically set based on request host" branch that fired
when ``tidal.redirect_uri`` config was empty AND the request didn't
come from localhost. That fallback overrode the TidalClient
constructor's safe default (``http://127.0.0.1:<port>/tidal/callback``)
with a uri built from request.host like
``http://192.168.x.x:8889/tidal/callback``. Tidal compares strings
exactly so this never matched the documented portal registration and
the user got 1002 before the consent screen even rendered.
The trap is the SoulSync settings UI displays the default URI as the
placeholder + "Current Redirect URI" display — but the placeholder
never gets saved to config unless the user explicitly clicks Save.
Most users who follow the docs (register the displayed default with
Tidal, then click Authenticate) hit the empty-config path and the
broken fallback.
Fix: drop the request-host fallback. Empty config falls back to the
constructor default that matches the documented portal registration.
The existing post-auth swap-step in the instructions page below
handles the Docker / remote-access case as designed:
1. SoulSync sends 127.0.0.1:8889 in the authorize URL → matches
portal → Tidal accepts.
2. User authorizes → Tidal redirects browser to 127.0.0.1:8889
(which fails locally — nothing on user's machine listens there).
3. Instructions tell user to swap 127.0.0.1 with the host they're
accessing SoulSync from.
4. Swapped URL hits the container's exposed callback port → auth
completes.
8 regression tests in tests/test_tidal_auth_redirect_uri.py:
- Configured redirect_uri sent verbatim (localhost / custom port /
explicit network IP)
- Empty config falls back to constructor default — NOT request.host
(the actual reported scenario, with explicit assertion message
warning if the bug returns)
- Empty config + localhost access uses the same default (sanity)

Smoke-testing the just-merged provenance PR against live logs revealed
the new ID-match block was silently no-opping: no [ExtID Match] /
[Provenance Match] log lines despite the code path being live. Tracing
revealed two related gaps in extract_external_ids' source detection:
1. **Underscore-prefixed key.** Deezer / Discogs / Hydrabase clients
tag normalized track dicts with ``_source`` (underscore prefix —
convention used in 8+ places across core/). The extractor only
looked for ``provider`` and ``source``, so Deezer-sourced tracks
silently returned no IDs.
2. **No provider field at all.** Spotify and iTunes raw API responses
carry ``id`` but no provider/source key of any kind. The extractor
couldn't disambiguate the native ``id``, so Spotify-primary scans
would have hit the same silent miss once the user switched primary
sources.
Two-part fix:
- ``extract_external_ids`` now recognizes ``_source`` as another
candidate provider field.
- New optional ``source_hint`` parameter lets the caller supply the
configured primary source as a fallback when the track dict has no
provider field of its own. Track-side provider field still wins
when present (defensive against a wrong hint).
Watchlist scanner now passes ``get_primary_source()`` as the hint so
both naming conventions (Deezer-style _source, Spotify-style no-tag)
get handled uniformly.
6 new regression tests cover:
- _source recognized for Deezer
- _source recognized for Hydrabase (cross-provider mapping)
- _source recognized for Discogs (no library column — verifies
graceful no-crash)
- source_hint disambiguates raw tracks for spotify/itunes/deezer
- track-side provider takes precedence over hint
- None hint defaults safely
Full pytest 1630 passed; ruff clean. After this lands and the server
restarts, watchlist scans should produce [ExtID Match] /
[Provenance Match] log lines for tracks already on disk regardless of
which metadata source the user has configured as primary.
Followup to fix/watchlist-external-id-match. The companion PR closed
the demand side — the watchlist scanner asks for tracks by external IDs
before falling back to fuzzy. But for users on Plex / Jellyfin /
Navidrome the supply side was still broken: tracks.spotify_track_id
(and the other ID columns) only got populated by the asynchronous
enrichment workers, sometimes hours after the file was actually
written. During that window the ID match fell through to fuzzy and
the bug returned.
We were already collecting every ID during post-processing — they
live in the `pp` dict in core/metadata/source.py:embed_source_ids and
get embedded into file tags. We just dropped the in-memory copy
afterwards.
This PR persists them and uses them:
- Schema migration adds spotify_track_id / itunes_track_id /
deezer_track_id / tidal_track_id / qobuz_track_id /
musicbrainz_recording_id / audiodb_id / soul_id / isrc columns +
indexes to the existing track_downloads table (already keyed by
file_path).
- core/metadata/source.py:embed_source_ids exposes pp["id_tags"] and
the resolved ISRC back to the import context as _embedded_id_tags
/ _isrc.
- core/imports/side_effects.py:record_download_provenance reads those
context fields and passes them to db.record_track_download, which
now accepts the new ID kwargs and persists them.
- New db.get_provenance_by_file_path with exact + basename-suffix
fallback (handles container mount-root differences between
download-time path and media-server-reported path).
- New db.backfill_track_external_ids_from_provenance copies IDs
from track_downloads onto a tracks row idempotently — COALESCE on
every column preserves any value the enrichment worker already
wrote (enrichment is more authoritative for late binding).
- database/music_database.py:insert_or_update_media_track (the
single insertion point used by every Plex / Jellyfin / Navidrome
sync) calls the backfill immediately after each INSERT/UPDATE.
- New core/library/track_identity.py:find_provenance_by_external_id
used as a second-tier fallback in watchlist_scanner.is_track_missing
_from_library — catches the window between download and media-server
sync. Caller checks os.path.exists on the provenance file_path
before treating it as "already in library" so a deleted file
doesn't prevent re-download.
Effect: freshly downloaded files become ID-recognizable to the
watchlist on the very next scan, no enrichment-wait window.
19 regression tests in tests/test_provenance_id_persistence.py:
- Schema migration adds expected columns + indexes
- record_track_download persists every ID kwarg
- record_track_download backward-compat (old kwargs still work)
- get_provenance_by_file_path: exact match, basename fallback for
mount-root differences, multi-record latest-wins, defensive None
- backfill: copies all IDs, preserves existing via COALESCE,
no-op when no provenance exists
- find_provenance_by_external_id: per-ID lookup, ISRC cross-bridge,
OR semantics, latest-wins on multiple matches
Out of scope: backfilling provenance for files downloaded BEFORE
this PR (their track_downloads rows don't carry the new IDs). Those
continue to wait for enrichment. Acceptable — only affects historical
files; new downloads benefit immediately.

Reported case (CAL): a track already on disk got re-downloaded by the
watchlist scanner on every scan. Library DB had stale album metadata
for the file (track tagged on album "Left Alone") while the metadata
source reported it on a different album ("NPC" single). The
title+artist+album fuzzy block correctly said the album names didn't
match and declared the track missing — but the file's stable external
IDs (Spotify ID, ISRC, etc.) unambiguously identified it as the same
recording.
The earlier compilation-album fix (PR #461) handled qualifier drift
("OST" vs "Music From The Motion Picture"). This case is two
genuinely different album names referring to the same song.
Fix: provider-neutral external-ID short-circuit before the fuzzy
block in `is_track_missing_from_library`. Pulls every recognized ID
off the source track (Spotify / iTunes / Deezer / Tidal / Qobuz /
MusicBrainz / AudioDB / Hydrabase / ISRC), runs a single SELECT
against the indexed external-ID columns on the `tracks` table, and
treats any hit as "track exists in library — don't re-download".
If no IDs are available (older imports without enrichment, library
scans that didn't populate external IDs), falls through to the
existing fuzzy logic so the safety net stays intact.
New `core/library/track_identity.py` module with two helpers:
- `extract_external_ids(track)`: handles dict and object-style track
shapes, direct-field aliases (spotify_id / spotify_track_id /
SPOTIFY_TRACK_ID), and provider-disambiguated native `id` fields
(when track has `provider='deezer'` and `id='X'`, treats X as a
Deezer ID).
- `find_library_track_by_external_id(db, external_ids,
server_source)`: builds an OR of indexed column matches with
IS NOT NULL guards, optional server_source filter that also
passes legacy NULL rows, single-row LIMIT.
ISRC bridges across providers — a library track imported via Deezer
can be matched against a Spotify scan when both sides carry the
same ISRC.

Reported case (CAL): with lossy_copy.enabled=True,
lossy_copy.delete_original=True, and codec=mp3, every download left
both the original FLAC AND the converted MP3 in the target folder.
Users opting into a lossy-only library ended up dual-format on
every import.
Root cause: ``core/imports/file_ops.py:create_lossy_copy`` reads
``lossy_copy.codec`` and ``lossy_copy.bitrate`` from config but never
reads ``lossy_copy.delete_original``. The setting is only consulted
by the pre-move source-vanished check at
``core/imports/pipeline.py:651`` (so the pipeline knows to look for
a lossy variant when the FLAC has already moved on), but no code
path actually deletes the source after conversion.
Fix: after ffmpeg returns success and the QUALITY tag is written,
check ``lossy_copy.delete_original`` and ``os.remove`` the original
when enabled. Belt-and-suspenders:
- Same-path guard (``os.path.normpath(out_path) != os.path.normpath(final_path)``)
prevents accidentally wiping the just-converted file if a future
codec choice somehow resolves out_path to the source path.
- ``FileNotFoundError`` is treated as success (concurrent worker /
dedup cleanup got there first).
- Other ``OSError`` (permission denied, locked file) is logged but
doesn't propagate — the conversion already succeeded, the user just
has to clean up the original manually.
Failure paths skip the delete:
- ffmpeg returns non-zero → returns None, original stays
- lossy_copy.enabled=False → early return before conversion runs
- delete_original=False (default) → original stays

Note: this PR does NOT address the second bug CAL mentioned (track
re-downloaded despite already existing on disk). That symptom is
caused by stale album metadata on the user's existing files — the
library DB has the track tagged on a different album than the
metadata source reports — combined with wishlist.allow_duplicate_tracks
defaulting to True. Same class of issue partially addressed in PR
fix/watchlist-redownload-and-duplicate-detection but compilation-
album drift is the only currently-handled case. Tracking separately.
Discord-reported (Foxxify): logging in to Qobuz via the Connect
button on Settings showed "Connected: <username> (Active)" but
underneath an error said "Qobuz not authenticated...", and the
dashboard indicator stayed yellow. Saving settings or reloading the
tab didn't help.
Root cause: SoulSync runs two QobuzClient instances side by side —
one through soulseek_client.qobuz for the /api/qobuz/auth/* endpoints,
and a second owned by the enrichment worker thread for thread safety.
The login flow only updated the auth-flow instance's in-memory state
(plus persisted to config). The dashboard's "configured" check at
web_server.py:3371 reads
``qobuz_enrichment_worker.client.user_auth_token`` — the WORKER's
instance — which still believed itself unauthenticated. The
connection-test step at core/connection_test.py:370 hits the same
worker instance for the same reason.
Fix: add ``QobuzClient.reload_credentials()`` — a public, network-free
method that re-reads the saved session from config and updates the
instance's in-memory state + session headers. Call it on the
enrichment worker's client immediately after a successful
``/api/qobuz/auth/login``, ``/api/qobuz/auth/token``, or
``/api/qobuz/auth/logout`` so the two instances stay in lockstep
without waiting for the next process restart.
Unlike the existing ``_restore_session()`` this skips the network
probe — the caller has just authenticated, so the token is known
good. A small ``_sync_qobuz_credentials_to_worker()`` helper in
web_server.py wraps the call so all three endpoints share one path.

Followup to the enrichment-bubble registry consolidation. The

/api/discogs/{status,pause,resume}
/api/deezer/{status,pause,resume}
/api/spotify-enrichment/{status,pause,resume}

The dashboard's enrichment-status bubbles (MusicBrainz, AudioDB,
Discogs, Deezer, Spotify, iTunes, Last.fm, Genius, Tidal, Qobuz) each
had its own copy-pasted /status, /pause, /resume route in web_server.py
— 30 routes that differed only in the worker reference and a couple
of per-service quirks (Spotify's rate-limit guard, Last.fm/Genius
yield-override behavior, Tidal/Qobuz extra status fields).
Replace them with a registry-driven blueprint:
- core/enrichment/services.py declares an EnrichmentService dataclass
with worker_getter, config_paused_key, pre_resume_check,
auto_pause_token, and extra_status_defaults — all variation captured
as data, no branching on service id.
- core/enrichment/api.py exposes a Flask blueprint with three routes
(/api/enrichment/<service>/{status,pause,resume}). Per-service
quirks are honored via the descriptor: Spotify's rate-limit ban
still returns 429 with `rate_limited: true`, Last.fm/Genius still
drop the auto-pause token and add the yield override, Tidal/Qobuz
still merge `authenticated: false` into the fallback payload.
- web_server.py registers all 10 services after their workers
initialize, wires the host-side hooks (config_manager.set,
_download_auto_paused.discard, _download_yield_override.add), and
registers the blueprint.
- webui/static/enrichment.js polling + click handlers now hit the
generic endpoints. The per-service `update<Service>StatusFromData`
functions are unchanged — they still process the same payload.
This is the cutover step. Old per-service routes are intentionally
left in place as a fallback during the soak period — they currently
have zero callers in the codebase and will be deleted in a follow-up
patch once production has run on the new pipeline for a few days.
27 new tests in tests/test_enrichment_services.py cover the registry
behavior + every quirk path through the generic blueprint (rate-limit
guard, auto-pause token cleanup, persisted-pause config keys, extra
default fields, worker-not-initialized fallback, exceptions). Full

Self-review of the previous commit found a real false-positive risk in
the new filename-bucket pass: two unrelated songs that happen to share
a canonical filename (e.g. ``Yellow.mp3`` by Coldplay vs by some other
artist) would be grouped because all metadata gates were dropped.
The filename pass now layers a safety net under ``require_metadata_match=False``:
- If both rows carry a duration: must agree within 3 seconds. Same
source download = identical duration; a 3+ second gap means
different recordings.
- Else if both rows carry an artist: relaxed 0.6 similarity check —
catches dedup orphans that share an artist tag while rejecting
strangers-with-same-filename.
- Else (no duration AND at least one artist blank): skip — too little
signal to safely group.
5 additional regression tests cover the false-positive prevention
paths plus the genuine dedup-orphan scenarios that must still be
caught after the safety net.
Two related bugs reported on Discord by Mushy.
1. The watchlist re-downloaded the same OST track up to 7 times.
``is_track_missing_from_library`` compared Spotify's album name and
the media-server scan's album name with a raw SequenceMatcher at a
strict 0.85 threshold. Compilations and soundtracks routinely fail
this — Spotify reports
``"Napoleon Dynamite (Music From The Motion Picture)"`` while the
Plex / Navidrome / Jellyfin tag scan saves it as
``"Napoleon Dynamite OST"``. Raw similarity ≈ 0.49, so the scanner
declared the track missing on every 30-minute scan and added it back
to the wishlist. The wishlist then issued a fresh download. slskd
appended ``_<19-digit-ns-timestamp>`` to each new copy because the
target file already existed, and the user ended up with seven copies
of one song in one folder.
Fix: extract two pure helpers — ``_normalize_album_for_match``
strips qualifier parentheticals (Music From X, OST, Deluxe Edition,
Remastered, Anniversary, etc.) and trailing dash-clauses;
``_albums_likely_match`` checks equality after normalization,
substring containment, and a relaxed 0.6 fuzzy ratio. A volume /
part / disc / standalone-trailing-number guard rejects pairs like
``"Greatest Hits Vol. 1"`` vs ``"Greatest Hits Vol. 2"`` so the
relaxed threshold doesn't introduce false positives on serialized
releases. After this change the Napoleon Dynamite case collapses
to ``"napoleon dynamite" == "napoleon dynamite"`` via the equality
short-circuit and the redownload loop dies.
2. The duplicate detector found only one of the seven dupe files.
The detector buckets tracks by the first 4 chars of their normalized
tag title. Files written by slskd directly into a library folder
often get inconsistent (or blank) tags from the media-server rescan,
so the seven copies were bucketed apart by parsed title and never
compared.
Fix: refactor the per-bucket comparison into ``_scan_bucket``, then
add a second pass — ``_build_filename_buckets`` re-buckets leftover
tracks by canonical filename stem (slskd dedup tail stripped via
``_strip_slskd_dedup_suffix``, same regex the import-cleanup PR uses)
plus extension. Filename agreement is itself strong evidence the
files came from the same source download, so the second pass calls
``_scan_bucket`` with ``require_metadata_match=False`` to skip the
title / artist / cross-album gates. The same-physical-file guard
still runs so bind-mount duplicates aren't flagged.
72 new regression tests across two files cover the album-match
helpers (28 tests including the Napoleon Dynamite scenario, 7 volume
disagreements, 8 positive/negative pairs, 5 defensive cases) and the
new filename-bucket pass (16 tests across bucket construction, scan
integration, and existing title-pass behavior). Full pytest 1509
passed; ruff clean.
Reported by Mushy in Discord.
slskd appends "_<19-digit unix-nanosecond timestamp>" to a downloaded
filename when the destination already contains a same-named file
(concurrent downloads of the same track, partial-file retries after a
connection drop, cancelled-then-redownloaded files, the same track
surfacing in multiple synced playlists). The file-finder code already
recognized the suffix when matching a download to its source — but
after the canonical file moved into the library, the leftover
"_<timestamp>" siblings sat orphaned in the downloads folder forever.
Reported on Discord by Shdjfgatdif.
cleanup_slskd_dedup_siblings() runs at the end of each successful
import (3 safe_move_file sites in pipeline.py) and prunes any
remaining siblings that strip down to the canonical stem with the
same extension. Conservative match (>= 18 trailing digits) keeps
legitimate filenames like "Track 5" and "Album 1995" untouched. Per-
file unlink failures are swallowed so a single locked file doesn't
block the rest.
17 regression tests cover the suffix-strip primitive, orphan removal,
no-op cases, mismatched extensions, subdirectories, and partial-failure
recovery.
Importing web_server fires utils.logging_config.setup_logging at
module-init, which clears + re-installs handlers on the shared
'soulsync' logger and pins its level to the user's configured
value. That mutation leaks across tests in the same pytest process.
This file runs alphabetically before test_library_reorganize_orchestrator,
so the leak broke test_watchdog_warns_about_stuck_workers downstream
— it relies on caplog capturing soulsync.library_reorganize warnings
via root-logger propagation, and the reconfigured logger's new
handler chain swallowed those records before they reached caplog
(caplog.records came back empty even though pytest's live-log
capture clearly showed the warning fired).
Adds an autouse fixture that snapshots the soulsync logger's
handlers, level, and propagate flag before each test in this file
and restores them afterwards. Pollution stays scoped to this file.
tests/test_tidal_auth_instructions.py also imports web_server but
runs alphabetically AFTER test_library_reorganize_orchestrator so
it never tripped this — fix is scoped here, not a project-wide
conftest, so we don't change behaviour for unrelated test files.
- Flatten the Spotify service-status rendering so it shows rate-limit and recovery states explicitly, while otherwise displaying the active metadata provider directly.
- Keep the Spotify auth controls and metadata-source picker aligned with the real session state after authenticate and disconnect flows.
- Return "Unmapped" for unknown metadata source labels instead of implying iTunes.
- Update the metadata registry tests to cover the new label fallback.
- Send Spotify auth completion back to the opener so the settings page refreshes immediately
- Make the local auth flow go straight through to Spotify instead of showing the temporary instruction page
- Keep the remote/docker instruction page available for manual callback setups
- Sync Spotify status, connect/disconnect buttons, and metadata source selection after auth and disconnect
- Keep the disconnect behavior aligned with the active primary metadata source
- Hide the auth button when a Spotify session is active
- Treat disconnect as a session change, not a provider swap
- Share metadata source labels in the registry
- Tighten rate-limit copy around Spotify-specific behavior
Discord-reported (fresh.dumbledore + maintainer ack): the
/api/import/singles/process route iterated staging files through a
plain Python for loop. Per-file work is dominated by metadata
search round-trips (Spotify/iTunes/Deezer/Discogs), so a multi-
track manual import on a typical home network was painfully slow.
Adds a dedicated import_singles_executor (3 workers) alongside the
existing executor pool, and refactors the route to submit every
file at once and aggregate results via as_completed. Worker count
balances throughput against any single provider's per-source rate
limits — the same shape used by missing_download_executor.
Extracts the per-file pipeline into _process_single_import_file
which returns a typed (status, payload) outcome:
- ("ok", final_title) on success
- ("error", message) for missing/malformed input or pipeline failure
The worker wraps its own exceptions so a single bad file can't
crash the batch; the route adds a belt-and-suspenders try/except
around future.result() for any worker-level surprises.
Pipeline thread-safety verified: post_process_matched_download
already serializes per-file via post_process_locks (one lock per
context_key — and each import gets a unique UUID context_key), DB
writes serialize through SQLite's WAL + busy_timeout, metadata
registry uses RLocks, no bare module-level mutable state.
Adds 9 regression tests:
- 4 worker-contract tests (missing file, malformed match, pipeline
exception wrapping, happy-path return shape)
- 2 executor-config tests (worker count, thread name prefix)
- 1 integration test that proves the route actually parallelizes
by checking wall-clock duration is well under sequential cost
- 1 mixed-outcome aggregation test
- 1 worker-crash recovery test
Doesn't address the related "stops on tab close" complaint —
that's a separate request-lifecycle issue that needs job_id +
polling, not just parallelism.
Discord-reported (winecountrygames + fresh.dumbledore): "Import only
makes Albums folder no singles or eps". Users with a
${albumtype}s/$albumartist/... album_path template saw an "Albums"
folder fill up correctly but never any "Singles" or "EPs" folder.
build_import_album_info detected an album using
``total_tracks > 1`` AND ``album_name != track_title``. Spotify
singles fail both — total_tracks is 1 and the album is usually
named after the song. The result was that staging/auto-import
routed singles through single_path, which doesn't honour
$albumtype, so the user's per-type folder layout never applied.
Now also treats the metadata source's explicit release-type
classification ("single", "ep", "compilation") as evidence that
this is an album-shaped release, so it routes through album_path
and the user's $albumtype substitution runs. The default fallback
value "album" is deliberately excluded from this check so
single-track downloads with no real metadata behave exactly as
before.
Adds 10 regression tests covering the reported scenario, EP and
compilation explicit types, and three guards: normal multi-track
albums still detected, default 'album' type falls through, and
empty/unknown types fall through.
Discord-reported: clicking the Tidal "Authenticate" button on a
Docker setup landed users on a remote-access instructions page that
told them their callback URL would look like
http://127.0.0.1:8888/tidal/callback?code=... — Spotify's port,
hardcoded into the Tidal instructions. Users who followed those
instructions literally saved 8888 into their tidal.redirect_uri
setting; that mismatched their Tidal Developer App's registered
:8889 redirect URI and Tidal returned error 1002 (invalid redirect
URI) on every auth attempt.
Pull the port from the actual TidalClient.redirect_uri the OAuth
URL was just built with (urlparse), with the SOULSYNC_TIDAL_CALLBACK_PORT
env var as fallback when the URI can't be parsed. Both the Step 2
example and the Step 3 highlighted URL now reflect whatever Tidal
port the user is actually configured to use.
Adds 3 regression tests covering the reported scenario, custom
callback ports via SOULSYNC_TIDAL_CALLBACK_PORT, and a defensive
fallback when redirect_uri is unparseable. Tests hit the real
/auth/tidal route through Flask's test client and assert the
rendered HTML, so future hardcoded ports get caught immediately.
The /api/library/watchlist-all-unwatched endpoint required the
user's currently active metadata source's ID column on each library
artist. A Spotify-primary user with library artists only matched
against iTunes or Deezer saw them silently skipped — surfacing on
Discord as "Library and Watchlist not syncing correctly". The per-
artist Enhanced View sync sometimes "fixed" them because it triggered
metadata enrichment that occasionally populated the missing Spotify
ID, but couldn't help artists Spotify simply doesn't carry.
Extracts the picker as a standalone helper so it can be tested
directly:
core/watchlist/source_picker.py:pick_artist_id_for_watchlist
Picks the active source first when available, then falls back through
spotify -> itunes -> deezer -> discogs in registration order. Empty
strings count as missing. Numeric IDs are coerced to str so SQLite's
TEXT columns store them in the same form library code reads back.
Returns (None, None) only when the artist has zero source IDs — the
only legitimate skip reason now.
Adds 10 regression tests covering active-source priority for each
supported primary, fallback ordering through every secondary, the
zero-IDs base case, unrecognized active source (e.g. hydrabase still
falls through), empty-string handling, and numeric coercion.
Discord-reported scenario: a single "Super Single" by Artist1 feat.
Artist2 is also on Artist1's "Super Album". When the album is fully
owned, Artist1's discography correctly shows the single as complete,
but Artist2's discography (where the same track also appears as a
single) shows it as missing.
Two layers needed for the fix:
Scanner: the Jellyfin/Emby path was keeping only ArtistItems[0],
which is almost always equal to the album artist — so the
distinguishing per-track credit was silently suppressed. Now joins
every ArtistItems entry with "; " and stores the value when there
are multiple credits OR when the single credit differs from the
album artist. Plex's originalTitle already carries the full multi-
artist tag, so Plex users benefit without needing the scanner change.
Scorer: _calculate_track_confidence now splits track_artist on the
common multi-artist delimiters real-world tags use (",", ";", "&",
"feat.", "ft.", "featuring", "vs.", "x") and scores each piece
independently against the search artist, taking the max along with
the whole-string similarity as the floor. Never reduces a score —
purely additive matching for previously-missed featured-artist
credits.
Adds 12 regression tests covering the reported scenario, primary-
artist back-compat, every delimiter variant (parametrized), no-
regression on exact match, and the scanner storing every ArtistItem.
Existing Jellyfin-scanned rows persist their old single-artist value
until the next library scan rewrites them; Plex rows benefit
immediately on next match without needing a rescan.
Re-enabling the previously-dead album-aware fallback could in
theory leak false positives if its 0.8 album-title floor were
ineffective. Pin the floor with a clearly-mismatched album hint
("Disney Hits" against "Ray of Light") and assert the search
returns no match. Distinct artist names with no shared words so
the main path actually fails through to the fallback (the prior
draft used "Different Artist" / "Real Artist" which both contain
"Artist" and scored above the main path's threshold, never
reaching the fallback at all).
Two bugs surfacing the same user-reported symptom: a Vaiana OST
track ("Where You Are" by Christopher Jackson) wouldn't match against
a Plex/Emby library because the album sits under the album artist
(Lin-Manuel Miranda).
Bug 1: the data was already there but scoring ignored it. The DB
schema has a tracks.track_artist column, the scanner populates it
from Plex's originalTitle and Jellyfin's ArtistItems[0], and the SQL
WHERE clause already searches it — but _rows_to_tracks dropped the
column on its way to the Python object, and _calculate_track_confidence
only scored against the album-artist JOIN. Candidates whose track-
artist matched got returned by the search and then immediately
filtered out by the low confidence score.
Fix: _rows_to_tracks now propagates row['track_artist'] onto the
returned object, and _calculate_track_confidence takes the better of
(album-artist similarity, track-artist similarity) so soundtracks
match through whichever credit the search query carries.
Bug 2: the album-aware fallback path constructed DatabaseTrack with
kwargs the dataclass doesn't accept (artist_name, album_title,
server_source). Every row TypeError'd, the outer except swallowed it
silently, and the fallback never matched anything since the column
was added — invisible because nothing logged it.
Fix: build DatabaseTrack with valid fields and attach the joined
columns afterwards, the same pattern _rows_to_tracks uses.
Adds 6 regression tests covering: track-artist match (the OST case),
album-artist still matches, scorer takes the better of the two,
defensive handling for tracks without track_artist, search-path
attribute propagation, and the previously-dead album-aware fallback.
The "Clean Search History" automation card kept showing a stale
'DownloadOrchestrator' object has no attribute 'base_url' error
even after the underlying handler bug was fixed in 77d20e9. Root
cause is in the engine, not that handler: AutomationEngine only
captured uncaught exceptions into last_error. Handlers that
report failure by RETURNING {'status': 'error', ...} were treated
as successful from the engine's perspective, so subsequent
gracefully-failing runs never updated the row to reflect the
current state.
Both the timer (run_automation) and event (_handle_event_trigger)
paths now extract the error string from a result whose status is
'error', falling through 'error' -> 'reason' -> 'message' -> a
placeholder so last_error is never None on actual failures
regardless of which key the handler chose. Existing behaviour for
raised exceptions and successful runs is preserved.
Also normalizes _auto_clean_search_history's return key from
'reason' to 'error' so older deployed engines that only check
the canonical key still see the failure.
Adds 7 regression tests covering every result shape the engine
might receive.
