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

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
1677 passed locally.

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

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.
10 new regression tests cover the populate / clear / partial-config
paths plus the actual two-instance-sync scenario from the bug report.
Full pytest 1555 passed (the one pre-existing flake in
test_tidal_auth_instructions.py is order-dependent and unrelated).
- keep existing /api/image-proxy URLs from being wrapped again
- reuse the shared metadata package instead of duplicating URL logic in web_server.py
- add regression coverage for proxy passthrough and internal URL normalization
- Prefer real Spotify IDs when importing Spotify contexts
- Skip numeric fallback IDs so Deezer values do not leak into spotify_* columns
- Add regressions for import context and SoulSync library writes
- Keep the route test asserting the Spotify album link
- Keep the primary metadata provider snapshot generic and move Spotify auth/rate-limit details into a separate status object.
- Update the websocket fixture and dashboard/settings consumers to read the two buckets independently.
Followup to the enrichment-bubble registry consolidation. The
dashboard polling + click handlers all hit
/api/enrichment/<service>/{status,pause,resume} now, so the 30
hand-rolled per-service routes in web_server.py have zero callers
and can come out:
/api/musicbrainz/{status,pause,resume}
/api/audiodb/{status,pause,resume}
/api/discogs/{status,pause,resume}
/api/deezer/{status,pause,resume}
/api/spotify-enrichment/{status,pause,resume}
/api/itunes-enrichment/{status,pause,resume}
/api/lastfm-enrichment/{status,pause,resume}
/api/genius-enrichment/{status,pause,resume}
/api/tidal-enrichment/{status,pause,resume}
/api/qobuz-enrichment/{status,pause,resume}
Worker init blocks stay (they still construct the workers + persist
pause state). Section comment headers are preserved with a one-line
note pointing readers at the new generic blueprint.
Test fixtures in tests/conftest.py and
tests/metadata/test_enrichment_events.py also updated to use the
new URL paths so they reflect production reality. They were
synthetic stubs that never depended on the production routes —
purely cosmetic alignment.

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
suite 1541 passed; ruff clean.
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.
The fixture used the wrong env var name (SOULSYNC_DB_PATH) when trying
to redirect ConfigManager at a tmp directory. ConfigManager actually
reads DATABASE_PATH (config/settings.py:49), so the test ConfigManager
loaded — and then saved — at the user's real database/music_library.db.
The retry stub in test_lock_errors_during_retries_log_at_debug_not_error
calls the real _save_to_database after its mocked failures, which then
clobbered the encrypted app_config row with the test fixture's stub
payload {"plex": {"base_url": "http://example.test"}}.
Three layers of fix so this can't happen again:
- Use the correct env var (DATABASE_PATH).
- Pin mgr.database_path / mgr.config_path on the instance after
construction, so the test fixture's tmp paths win even if
ConfigManager's resolution logic changes.
- Assert the resolved database_path is rooted under tmp_path before
returning the fixture, so the test refuses to run if it would touch
a non-tmp DB.
When users bind the same host music directory into both SoulSync
(e.g. /app/Transfer) and a media server like Plex (e.g.
/media/Music), both scans add a track row pointing at the same
physical file via different mount paths. The detector previously
flagged those as duplicate groups even though there's only one
file on disk.
New _is_same_physical_file helper filters pairs where:
- The trailing 3 path segments match (filename + album + artist
folder), so they're the same release on disk.
- The leading mount roots actually differ.
- Durations agree within 1s when both rows carry duration data.
Adds 10 regression tests covering the reported scenario plus
edge cases (Windows separators, case differences, missing
durations, sibling-album false-positive guard).
Pin the new save-retry contract so future changes can't silently
re-introduce the spam reported in #434:
- Happy-path saves emit zero ERROR logs.
- Transient locks during retries log at DEBUG, not ERROR.
- Six attempts run before giving up, with the documented backoff
schedule (0.2 + 0.5 + 1.0 + 2.0 + 4.0s).
- Genuine exhaustion logs a single ERROR and writes config.json.
- sqlite3.OperationalError("database is locked") routes to DEBUG;
any other OperationalError still logs ERROR.
- _connect_db() actually applies WAL + busy_timeout + synchronous=NORMAL.
Also moves `import time` from inside _save_config to the module
top so the tests can monkeypatch sleep cleanly.
- normalize album.total_tracks before comparing it in wishlist classification
- avoid mixed-type comparisons when provider payloads serialize track counts as strings

- keep album.image_url and album.images populated so the wishlist UI can render the cover consistently
- add a regression test covering provider payloads with image_url on both the track and artist
- search metadata providers in source-priority order for each generated query instead of caching one client for the whole scan
- keep the quality-scanner worker provider-neutral and preserve the no-provider error path
- update the quality-scanner tests and remove the obsolete web_server spotify_client injection
- Switch the download lifecycle over to the neutral wishlist track helper name

- add neutral wishlist payload helpers while keeping legacy Spotify aliases
- route wishlist removal and classification through generic track data
- keep API and service compatibility for existing callers
Final lift in the web_server.py extraction effort. Pulls two route
handlers + one background worker out of `web_server.py` into new
focused packages:
- `core/streaming/prepare.py` — 258-line stream-prep worker that
downloads a track to the local Stream/ folder for the browser audio
player.
- `core/playlists/explorer.py` — 305-line route handler for
`POST /api/playlist-explorer/build-tree` that streams an NDJSON
discography tree from a mirrored playlist.
What `prepare_stream_task` does:
1. Reset stream state to 'loading' with the new track info.
2. Clear any prior file from Stream/ (only one stream lives there).
3. Spin up a fresh asyncio event loop and `soulseek_client.download()`.
4. Poll progress every 1.5s. Queue timeout 15s; overall 60s.
5. On succeeded + bytes-match: find the file with retry, move into
Stream/, signal slskd completion, mark state 'ready' with file_path.
6. On error/timeout/cancel: state goes to 'error' or 'stopped'.
7. Finally: tear down the event loop cleanly.
What `playlist_explorer_build_tree` does:
1. Validate request, load playlist + tracks from DB.
2. Pick active metadata source (Spotify if authed, else fallback).
3. Group tracks by artist using discovered matched_data when the
provider matches the active source.
4. Stream NDJSON: meta line → one artist line per group → complete line.
5. Per artist: cache check → resolve discography → tag releases with
`in_playlist` flag based on title-similarity match → filter by mode
(`albums` = only matches; `discographies` = full disco).
6. Mark playlist as explored on completion.
Strict 1:1 byte parity:
Both functions exposed their dependencies through proxy patterns
established in earlier lifts (PR4–PR8). For prepare_stream_task,
`stream_state` is a deps property; for the explorer, Flask `request` /
`jsonify` / `Response` are injected via deps so the lifted body keeps
its native syntax. Both lifts verified ZERO diff against the original
after `deps.X` → global X normalization.
258 lines orig = 258 lines lifted (prepare_stream_task).
305 lines orig = 305 lines lifted (explorer).
Bonus cleanup: web_server.py's module-level `import shutil` and
`import glob` were now unused (only `_prepare_stream_task` used them
at module scope; every other reference is via inline `import shutil`
in respective function bodies). Removed both module-level imports —
ruff caught the F811 redefinitions and confirmed they're truly
redundant.
Dependencies for `PrepareStreamDeps` (11 fields):
config_manager, soulseek_client, stream_lock, project_root,
docker_resolve_path, find_streaming_download_in_all_downloads,
find_downloaded_file, extract_filename, cleanup_empty_directories,
plus 2 stream_state property delegates.
Dependencies for `PlaylistExplorerDeps` (9 fields):
Flask request/Response/jsonify, spotify_client, get_database,
get_active_discovery_source, get_metadata_fallback_client,
get_metadata_fallback_source, get_metadata_cache.
Tests: 6 new under tests/streaming/test_prepare.py (state init,
Stream/ folder creation + clearing, download-init failure, completed
+ moved + ready state, partial-bytes incomplete-warning path) plus 9
new under tests/playlists/test_explorer.py (5 validation early-exit
paths, streaming response shape with meta/complete lines, mark-
explored side effect, discovered-artist grouping using matched_data,

End of the web_server.py extraction effort. Started at ~45,000 lines
across PR4–PR8 + this commit; finished around 35,000 lines with the
heavy worker + route logic now living in domain-cohesive packages
under core/. The remaining bulk in web_server.py is route handlers,
service initialization, and the deferred 1530-line
`_register_automation_handlers` (startup-only, marginal lift value).
Pulls the 284-line artist quality enhancement helper out of
`web_server.py` into a new `core/artists/` package. Flask route handler
split: route + request parsing stay in web_server.py, the body lifts to
a pure function returning `(payload_dict, http_status_code)`.
What `enhance_artist_quality` does:
1. Validate request: track_ids must be non-empty, artist must exist.
2. Build a `track_lookup` from `database.get_artist_full_detail` so each
selected track resolves with its album context.
3. Per track:
- Read current quality tier from the file extension.
- Build `matched_track_data` for the wishlist entry, in priority
order:
- Spotify direct lookup via stored `spotify_track_id` (preferred).
Uses raw API data when available; otherwise rebuilds the payload
and pulls album images via a follow-up `get_album` call.
- Spotify search fallback using matching_engine queries with
artist+title similarity scoring (album-type bonus for albums,
smaller bonus for EPs). Stops at first >= 0.9 confidence match.
- iTunes/fallback source search with the same scoring shape.
- Add to wishlist via `wishlist_service.add_spotify_track_to_wishlist`
with `source_type='enhance'` and a `source_context` carrying the
original file path, format tier, bitrate, original_tier, and
artist_name.
- Tally `enhanced_count` / `failed_count` / per-track failure reasons.
4. Return `{success, enhanced_count, failed_count, failed_tracks}` 200.
Dependencies injected via `ArtistQualityDeps` (7 fields) — spotify_client,
matching_engine, get_database, get_wishlist_service,
get_current_profile_id, get_quality_tier_from_extension,
get_metadata_fallback_client.
Diff vs original after `deps.X` → global X normalization is **1 line of
cosmetic drift** — the success return now uses an explicit `(payload, 200)`
tuple to keep all returns shape-consistent for the wrapper. Flask treats
`jsonify(x)` and `(jsonify(x), 200)` identically. 284 lines orig = 285
lines lifted, body otherwise byte-identical.
Tests: 10 new under tests/artists/test_quality.py covering input
validation (empty track_ids, artist not found), Spotify direct lookup
via raw_data, Spotify direct lookup with enhanced format requiring
album image rebuild, Spotify search fallback, iTunes/fallback source
match path, track-not-found and no-file-path failure modes, complete
no-match failure, and source_context payload assertions (enhance flag,
file path, format tier, bitrate, source_type).
Full suite: 1340 passing (was 1330). Ruff clean.
