6e5ea1d490 fix(downloads): wait for post-processing result
Do not mark a monitored transfer as successful as soon as slskd reports completion. The monitor now only submits the post-processing worker; that worker reports the real success or failure after finding, verifying, and importing the file. If post-processing cannot be scheduled, mark the task failed and release the batch slot. Add a regression test for the premature success path.

735dd73865 fix(repair): rewire Unknown Artist Fixer deferred imports (#646)
The "Fix Unknown Artists" repair job crashed on every run with:

    ImportError: cannot import name '_build_path_from_template' from
    'core.repair_jobs.library_reorganize'

Commit ca5c9316 ("Rewrite Library Reorganize job to delegate to per-
album planner") moved the private path-builder + quality-string
helpers out of `core.repair_jobs.library_reorganize` and into the
import pipeline. `unknown_artist_fixer.py:163` still imported them
from the old module — its scan() defers the imports to avoid pulling
web_server's Flask boot into the test harness, so the broken target
only surfaces at runtime when the user actually runs the job. The
tool was completely unrunnable.

Re-wired the deferred imports:

    core.repair_jobs.library_reorganize._build_path_from_template
        -> core.imports.paths.get_file_path_from_template_raw
    core.repair_jobs.library_reorganize._get_audio_quality
        -> core.imports.file_ops.get_audio_quality_string

Both replacements have identical signatures + return shapes (verified
by inspecting library_reorganize's pre-refactor implementations vs
the import-pipeline equivalents):

    get_file_path_from_template_raw(template: str, context: dict)
        -> tuple[folder: str, filename_base: str]
    get_audio_quality_string(file_path: str) -> str

No call-site changes needed beyond the import target.

2 new regression tests in `tests/test_unknown_artist_fixer.py`:

    test_deferred_path_imports_resolve — runs the same import
    statements scan() runs, so the NEXT refactor that moves these
    helpers fails CI rather than reaching the user.

    test_deferred_path_helper_shape_matches_fixer_usage — pins the
    `(folder, filename_base)` 2-tuple contract the fixer's unpack
    relies on. Catches return-shape drift even when the import
    target stays valid.

Audited every consumer of `core.repair_jobs.library_reorganize` —
only one stale import (this file). The test suite covers the only
production caller.

5 fixer tests pass (3 existing + 2 new regression guards).

79ad4d885d fix(quarantine): drop already-quarantined sources from candidate picker (#652)
When a file failed AcoustID verification and got quarantined, the next
auto-wishlist cycle would search for the same track, the deterministic
quality picker would re-select the same (uploader, filename) source,
re-download it, and re-quarantine it. Users woke up to hundreds of
duplicate .quarantined entries from a single bad upload — same source
URL repeatedly, byte-for-byte identical files.

Root cause: `SoulseekClient.filter_results_by_quality_preference` ranks
candidates by quality + bitrate density only. Quarantine history wasn't
consulted, so a high-bitrate FLAC upload with a wrong-track AcoustID
fingerprint kept winning the picker against every other candidate.

Fix shape:

- New helper `core/imports/quarantine.py::get_quarantined_source_keys`
  reads every quarantine sidecar's `context.original_search_result`
  and returns the set of `(username, filename)` tuples for O(1)
  membership checks. Sidecars missing the context field (legacy thin
  sidecars written pre-Feb 2026, or orphaned files) and corrupt JSON
  are skipped silently — defensive against transient FS / encoding
  issues.

- `SoulseekClient._drop_quarantined_sources` runs the membership
  filter against incoming TrackResults, drops matches, logs a single
  INFO line with the skip count. Called first inside
  `filter_results_by_quality_preference` so all four callers
  (search-and-download, master worker, validation, orchestrator)
  benefit transparently.

- Approving or deleting a quarantine entry removes its sidecar, so
  the dedup key disappears from the set on the next search — gives
  the user a way to opt back in to a previously-quarantined source
  without restarting the app.

7 helper tests cover: missing dir, empty dir, well-formed sidecars
collected as tuples, legacy sidecars skipped, empty source fields
skipped (so empty-string keys can't accidentally drop unrelated
results), corrupt JSON tolerated, duplicate quarantines collapse.

5 integration tests pin: clean candidates pass, known-bad candidates
drop, missing quarantine dir returns input unchanged, filesystem
errors swallowed (defensive), full `filter_results_by_quality_preference`
runs the dedup BEFORE the quality picker — so a high-quality
quarantined source can't win on bitrate.

692 existing download + import tests still green. Cosmetic surface
of the fix is invisible — same UX as today when no quarantine entries
exist; loop only kicks in once a sidecar has been written.

Out of scope: bulk-select / multi-delete UI for the quarantine tab —
S-Bryce mentioned this as a separate pain point in the issue, but
it's its own UX work, not a one-commit drive-by.

987409508b fix(metadata): surface MusicBrainz 'Other' release-groups in discography (#650)
S-Bryce reported that for some artists (Vocaloid producers, JP indie
acts, niche Western indie) the artist detail page was missing whole
release-groups visible on musicbrainz.org. Downloaded tracks from
those release-groups appeared in artist track counts but were not
bound to any visible album / single card — orphan "ghost" tracks the
user couldn't browse to.

Two duplicated bugs fed each other:

1. `core/musicbrainz_search.py` browsed MB release-groups with
   `release_types=['album', 'ep', 'single']`. MB's primary-type
   vocabulary is {Album, Single, EP, Broadcast, Other} — music
   videos, one-off web releases, and broadcast singles use Other.
   Pre-fix the filter dropped them at the API layer.

2. Three sites duplicated the same "raw primary-type → internal
   album_type" mapping with slightly different vocabularies and all
   silently defaulted unknown values (including 'Other') to 'album':

       core/musicbrainz_search.py  `_map_release_type`
       core/metadata/types.py      inline `{single:single, ep:ep}.get(...)`
       core/metadata/cache.py      Deezer-specific record_type guard

Letting Other through the filter without a real mapper would have
placed music videos in the Albums view alongside LPs — visually
misleading.

Fix shape:

- New `core/metadata/release_type.py` — single canonical mapper
  consumed by every provider's raw→Album projection. Knows the full
  MB vocabulary including 'other' and 'broadcast'; routes both into
  the singles bucket since they're functionally single-track
  releases. Compilation secondary-type override preserved (MB's
  canonical Greatest-Hits pattern is `primary=Album,
  secondary=[Compilation]`).

- `core/musicbrainz_search.py` `_map_release_type` becomes a thin
  alias for the new helper so the six internal call sites stay
  intact. API filter gains 'other'.

- `core/metadata/types.py` Album projection drops its inline mini-
  mapper and calls the canonical helper. Now also handles the
  compilation secondary-type override it was previously missing.

- The Deezer-specific cache.py guard stays as-is — Deezer's
  record_type vocabulary is closed (album|single|ep), not affected
  by this issue.

Verified end-to-end against MB for S-Bryce's artist (`46196b9c-affa-
4616-b53b-e967c8bd70e0`, inabakumori): pre-fix returned 22 release-
groups; post-fix returns 27, with the 5 extra all landing in the
Singles section with album_type='single' as intended.

23 new unit tests pin the mapper contract (case-insensitive primary
types, compilation secondary override, Other/Broadcast → single,
unknown → album default preserved, defensive empty/None inputs).
2 new tests in test_musicbrainz_search pin the API filter inclusion
of 'other' and the round-trip into the Singles bucket. All 516
existing metadata tests still green — refactor leaves historical
behaviour for {album, ep, single, compilation} unchanged.

54e4ba843f fix(soulseek): suppress connection-error log spam when slskd unreachable (#649)
When slskd_url is configured but the host is unreachable (slskd not
running, wrong port, host.docker.internal not resolving), the frontend's
/api/downloads/status polling fanned out to every download plugin
including Soulseek. soulseek_client._make_request hit a DNS / connect
failure on each poll and logged it at ERROR. Result: one
"Cannot connect to host host.docker.internal:5030" log line every
~2-3 seconds for the entire duration of any download — visible spam
even when the user wasn't using Soulseek at all.

Caught aiohttp.ClientConnectorError explicitly in both _make_request
and _make_direct_request. First failure emits one WARNING with
actionable context (start slskd, or clear soulseek.slskd_url if you
don't use Soulseek). Subsequent failures demote to DEBUG. The
_last_unreachable_logged flag resets on any successful (200/201/204)
response so a later outage warns again — suppression is per-outage,
not per-process-lifetime. Same shape as the existing _last_401_logged
suppression for auth failures.

The architectural gap (status polling fans out to soulseek even when
the user has soulseek disabled in their active download sources) is
intentionally left for a follow-up. The plugin-iteration code lives
in core/download_engine/engine.py and core/download_orchestrator.py;
threading a "skip-when-not-active" gate through every caller is a
bigger refactor than this user-facing log cleanup warrants. The
WARNING-once message tells the user what to do in the meantime.

5 new pinning tests cover the suppression contract: connection error
returns None (not raises), first failure WARNs + sets flag, repeats
stay quiet, successful response resets the flag, _make_direct_request
follows the same pattern, and non-connection exceptions still log at
ERROR so real bugs aren't hidden behind the new suppression.

daf9a527d9 feat(fix-popup): include MusicBrainz in the auto-search cascade
The Fix Track Match modal's auto-search was hardcoded to query only
Spotify -> Deezer -> iTunes, ignoring MusicBrainz entirely — even for
users with MB set as their primary metadata source. MB-niche recordings
(canonical entries with diacritics, fringe / non-mainstream tracks that
the commercial catalogues don't carry) had no chance.

Wiring:

- New `MusicBrainzSearchClient.search_tracks_with_artist(track, artist,
  limit)` for surfaces that already have title + artist split. Uses MB's
  bare-query mode (strict=False) — diacritic-folded, alias/sortname
  indexed — same recall rationale as the earlier MBID-paste endpoint.

- New route `GET /api/musicbrainz/search_tracks` mirrors the existing
  /api/{spotify,itunes,deezer}/search_tracks endpoints exactly: accepts
  `track`+`artist` (or legacy `query`) + `limit`, returns
  `{tracks: [{id, name, artists, album, duration_ms, image_url, source}]}`.
  Applies the same `core.metadata.relevance.rerank_tracks` pass Deezer /
  iTunes use, which is critical because MB's free-text scoring weighs
  title-text matches heavily and would otherwise rank cover / tribute
  recordings above the canonical version.

- `_search_tracks_text` gains a `min_score` parameter. The cascade path
  passes 20 (vs the enhanced-search-tab default of 80) so MB recordings
  whose title doesn't literally contain the artist name still enter the
  candidate pool — without that, "Army of Me" + "Bjork" only surfaces
  the HIRS Collective cover (score 100) and drops Björk's canonical
  recording (score 28). The rerank pass then surfaces Björk by artist
  match. Verified against real MB API: pre-fix returned only the cover;
  post-fix top 5 are all Björk.

- Fix popup `allSources` array (wishlist-tools.js) gets MB appended.
  The existing `activeIdx` reorder logic moves MB to the front when
  it's the active primary; otherwise MB sits last (1 req/sec rate
  limit makes it the slowest source).

7 new unit tests on the adapter: bare-query mode is used, missing
artist falls back to None (drops AND-clause), empty inputs short-circuit,
low-score candidates are kept for rerank to handle, default strict +
default min_score behaviour preserved for the existing search-tab path,
client errors are swallowed so the cascade falls through to the next
source.

Discogs intentionally absent — Discogs has no track-level search API
(see core/discogs_client.py:575 — returns []). Adding a Flask endpoint
that always returns empty would be a permanent no-op.

97f35de44e test(amazon): update search_albums test for derived-from-tracks behavior
Commit 478bcc5d (`fix(amazon): search albums/artists and track numbers
for t2tunes`) switched `search_albums` to query `types=track` and derive
Album objects from the album metadata on each track hit — Amazon's
album-type query is broken upstream. The matching test was left asserting
the old "filter out track hits → return []" behavior and has been failing
in CI ever since.

Rewritten to assert the current intended behavior: track hits yield
distinct albums by album ASIN, with the artist credit + name preserved.
No code change.

036faff8b1 feat(fix-popup): paste MusicBrainz URL/MBID to match directly
Power-user escape hatch on the Discovery Fix Track Match modal — when
fuzzy auto-search ranks the wrong recording among many same-title
versions (10 remasters, live cuts, alt sessions), paste the MusicBrainz
recording URL or bare UUID into the new field and resolve straight to
that record.

Layout:

- Shape adapter `get_recording_flat(mbid)` lives in
  `core/musicbrainz_search.py` next to existing `get_track_details`.
  Returns the flat Fix-popup track shape (artists as `string[]`,
  album as string, single `image_url`) — distinct from the
  Spotify-shaped nested dict `get_track_details` returns.

- New route `GET /api/musicbrainz/recording/<mbid>` is a thin wrapper:
  validates MBID format with an anchored UUID regex, calls the adapter,
  returns 400 / 404 / 200 with no inline shape massaging.

- Frontend `parseMusicBrainzMbid()` lives in `shared-helpers.js` —
  pure URL/UUID parser, reusable from other surfaces (failed-MB cache,
  manual match) without duplication.

- Fix modal HTML gets one new input row + button; existing search row
  and result render pipeline are untouched. New `lookupDiscoveryFixByMbid()`
  fetches the endpoint and feeds the single result through the existing
  `renderDiscoveryFixResults` -> confirm-dialog -> match pipeline, so MB-
  paste matches go through the exact same selection flow as auto-search
  results.

- Enter-key bound on the MBID input via a separate handler ref so its
  lifecycle matches the search-input handlers without conflating the
  two submit targets.

7 unit tests cover the adapter: happy path, empty/None MBID, MB returns
None, recording-without-release (empty album), multi-artist credits,
includes-list contract, and client-error swallow.

Out of scope: the Fix popup's fuzzy cascade is still hardcoded to
spotify/deezer/itunes regardless of which primary source the user has
configured. Adding MB to that cascade (when MB is the active primary)
is a separate concern.

43ed30b4d2 fix(musicbrainz): user-facing search recall + album-detail 404
Two bugs surfacing on the Fix popup and enhanced-search MB tab:

1. Strict Lucene phrase queries (`recording:"X" AND artist:"Y"`) killed
   recall on user-facing manual search — diacritics ("Bjork" vs canonical
   "Björk"), bracketed suffixes like "(Live)", and any AND-clause
   mismatch returned zero results. Added `strict: bool = True` param to
   `search_release` / `search_recording`; when False, sends a bare query
   joining title + artist so MB hits alias/sortname indexes with
   diacritic folding. `/api/musicbrainz/search` (Fix popup) and
   `core/library/service_search.py` (service tabs) now pass strict=False.
   Enrichment workers stay on strict mode — precision matters there
   because they auto-accept the top hit above a confidence threshold.

2. Every MB album click was silently 404-ing — `_render_release_as_album`
   passed `cover-art-archive` as an MB `inc` param, but it's not a valid
   include for the /release resource (MB rejects with 400). The CAA flags
   come back on every release response by default, so dropping the bad
   include preserves the image-scope picker logic intact.

Carry MusicBrainz IDs through similar-artist discovery, recommended artists, artist map serialization, and personalized playlist selection. Update DB migrations and lookup filters so similar_artist_musicbrainz_id is preserved on older schemas and used for source requirements and library exclusion.

Normalize MusicBrainz album adapter output for import context and add regression coverage for registry mapping, typed album conversion, and similar-artist filtering. Verified by user with 120 focused tests passing.

Add a shared track-level lookup that falls back from exact source/id to source_track_id and title/artist, then use it for wishlist adds, cleanup, and download analysis so mapped tracks are not re-added or redownloaded.

3a4017ea2b feat: artist-detail deep linking — /artist-detail/:source/:id
Artist detail pages previously always pushed /artist-detail to the URL,
so refreshing the page or sharing a link would drop users on a broken
empty page with no artist loaded.

URL format is now /artist-detail/:source/:id (e.g.
/artist-detail/spotify/4tZwfgrHOc3mvqsCAfo4LT or
/artist-detail/library/42). The source segment lets the backend
synthesize a response from the right metadata client without a DB hit.

Changes:

Client routing (legacy shell + TanStack bridge)
- buildArtistDetailPath / _getDeepLinkArtistDetail added to init.js;
  parse both new :source/:id and legacy bare :id formats so old
  bookmarks still work
- navigateToPage passes artistId + artistSource through to the router
  bridge, which builds the dynamic href instead of hardcoding route.path
- resolveShellPageFromPath / resolveLegacyShellPageFromPath use a prefix
  match so /artist-detail/* resolves to artist-detail page-id
- globals.d.ts typed for artistId / artistSource options
- activateLegacyPath and syncActivePageFromLocation (popstate) both
  restore artist from URL using skipRouteChange:true to avoid a
  re-navigation loop back to /artist-detail
- loadInitialData restores artist from URL on page load (router not yet
  mounted at DOMContentLoaded so legacy path runs unconditionally)
- Same-artist guard in navigateToArtistDetail prevents double-fetch
  when the router fires activateLegacyPath after the initial navigation

Server
- artist_source_detail.build_source_only_artist_detail now resolves
  artist name from the source API when none is supplied, so deep-link
  restores with an empty name string still render correctly

Tests
- test_spa_deep_linking: /artist-detail/42 and /artist-detail/spotify/ID
  both serve index.html
- bridge.test.ts: source-aware URL building and library fallback
- route-manifest.test.ts: prefix path resolution
- artist_source_detail: name resolved from source when input is empty

076cf9e516 Improve Soulseek album source selection
Add a conservative Soulseek album preflight scorer so album downloads choose a coherent slskd folder before per-track enqueue. The scorer compares album title, artist, year, track count, tracklist coverage, peer quality, and penalizes unexpected deluxe/remix/live-style folders.

Preserve hybrid source priority by only running Soulseek album preflight when Soulseek is the selected source or first in the hybrid order. If Soulseek is only a fallback behind another source, the normal hybrid flow is left alone.

Reuse the richest wishlist album context across tracks in the same album group so release date, artwork, album type, and album artist stay consistent for path generation. Also preserve peer-quality tie breakers when attempting equal-confidence candidates.

Tests cover correct-folder selection over larger wrong editions, Soulseek primary vs fallback hybrid behavior, shared wishlist album context, and peer-quality candidate ordering.

121651da2c Add amazon_id column to artists table for full source parity

source now looks up Amazon artists by slug before falling back to name match,
same as every other source. artist_source_detail already stamps artist_info
[source_id_field] = artist_id so the amazon_id is set on source-only payloads.

assertion back to strict equality (SOURCE_ONLY_ARTIST_SOURCES == SOURCE_ID_
FIELD.keys() holds again now that amazon has a column).

265fe5233e Fix Amazon artist detail: library upgrade lookup and artist images
Library upgrade: find_library_artist_for_source returned None immediately for
Amazon because SOURCE_ID_FIELD has no 'amazon' entry (no DB column for Amazon
artist IDs). The name-based fallback was unreachable. Fix: only skip the column
query when column is None, not the whole function — name lookup now runs for
any source when artist_name + active_server are provided.

Artist images: add AmazonClient._get_artist_image_from_albums so the standard
_get_artist_image_from_source path in metadata/artist_image.py can call it as
a fallback (same hook iTunes/Deezer/Discogs expose). Searches by unslugified
artist name, matches primary artist, fetches album cover from album_metadata.

Test: updated test_source_only_set_matches_mapping_keys → _contains_all_mapped_
sources to assert subset (not equality) — SOURCE_ONLY_ARTIST_SOURCES intentionally
includes sources without a DB column that rely on name-only lookup.

51e00d4ebf Fix Amazon Music search quality: images, dedup, explicit stripping, album/artist clicks
- All search_raw calls switched from single-type to types="track,album" — T2Tunes only
  returns results when both types are requested together
- _fetch_album_metas: parallel fetch (up to 5 workers) of album cover art via
  album_metadata(asin) — T2Tunes search results carry no image URLs
- search_tracks: populates image_url, release_date, total_tracks from album meta
- search_artists: strips feat. credits via _primary_artist() so "Artist feat. X" and
  "Artist ft. Y" collapse to one "Artist" entry; uses album cover as artist image
  stand-in (same approach as iTunes — T2Tunes has no artist images)
- search_albums: name-based dedup (display_name + artist key) instead of ASIN-based;
  populates image_url, release_date, total_tracks from album meta (cap 10 ASIN fetches)
- _strip_edition(): strips [Explicit]/(Explicit) from track/album names — explicit is
  the default version; Clean/Edited/Censored labels kept as-is so they stay distinct
- get_album(): applies _strip_edition to name and _primary_artist to artist so
  MusicBrainz preflight matching doesn't fail on "[Explicit]" album names
- get_album_tracks(): populates track_number and disc_number from T2TunesStreamInfo
  instead of hardcoding None — fixes track ordering in multi-track album downloads

14a99f47ab fix(tests): use asyncio.run() instead of get_event_loop() in amazon test helper
get_event_loop() raises RuntimeError on Python 3.11+ Linux when no loop
exists. asyncio.run() creates its own loop per call — no deprecation warning,

ff27effdae Amazon download client: write final size==transferred before returning file path
The download monitor blocks post-processing with a bytes-incomplete guard:
if size > 0 and transferred < size: continue

_stream_to_file throttles engine updates to every 0.5s. The last tick before
the file finishes typically leaves transferred slightly below the Content-Length
size in the engine record. Other streaming clients (YouTube, Tidal, HiFi, etc.)
use their own download threads and don't track bytes at all, so size stays 0
and the guard is always skipped. Amazon was the only client hitting it.

Fix: just before returning the file path from _download_sync, write a final
engine record update setting size == transferred == out_path.stat().st_size
(the decrypted output size). The bytes-incomplete guard then sees
transferred == size and falls through to trigger post-processing normally.

b4403ed393 Amazon download client: fix engine API calls in status methods
`get_all_downloads` was calling `engine.get_all_records()` — a method that
doesn't exist on DownloadEngine. Same story for `cancel_record` and
`clear_completed`. The engine exposes `iter_records_for_source`, `get_record`,
`update_record`, and `remove_record` — matching what every other streaming
client (Deezer, HiFi, Qobuz, SoundCloud, Tidal, YouTube) already uses.

With `get_all_downloads` silently returning `[]` on every call (the missing
method raised, `except Exception: return []` swallowed it), the download monitor
never saw Amazon records as complete — tasks stayed stuck at 0% even after the
file had fully downloaded.

Changes:
- `get_all_downloads` → `iter_records_for_source('amazon')`
- `get_download_status` → `get_record('amazon', id)`, no try/except
- `cancel_download` → `get_record` check + `update_record` (Cancelled) +
  optional `remove_record` — same pattern as deezer/hifi/etc
- `clear_all_completed_downloads` → iterate + `remove_record` for terminal
  states; returns True on no-engine (nothing to clear = success)
- `_record_to_status` drops the `download_id` argument; reads `rec['id']`
  instead (worker stores `'id'` in every record — `iter_records_for_source`
  returns the full record dict)

Tests updated to match: `iter_records_for_source` mock replaces
`get_all_records`, cancel test verifies `update_record`+`remove_record`,
clear test verifies only terminal-state records are removed, graceful-error
test replaced with no-records boundary test (exception propagation is handled
at the engine aggregator layer, not per-plugin).

ebda0b8613 fix(amazon): _record_to_status read 'filename' not 'original_filename'
The engine worker stores the encoded filename under the key 'filename'
(see worker.py dispatch). _record_to_status was reading 'original_filename',
which always returns "" — so every DownloadStatus emitted by
get_all_downloads/get_download_status had an empty filename string.

The download monitor builds lookup keys as
_make_context_key(download.username, download.filename). With filename=""
the key was always "amazon::" which never matched the task's
"amazon::B0B1234||Artist - Title" key. Monitor never detected Amazon
download completions, so tasks sat stuck at Downloading 0% forever even
though the files had actually downloaded.

Also fixes tests that had the same wrong key.

9fb63ff86d fix(amazon): add set_engine/set_shutdown_check so _engine gets wired
AmazonDownloadClient was missing set_engine() and set_shutdown_check().
The download engine auto-wires plugins by calling set_engine(self) at
registration time if the method exists (engine.py:136). Without it,
_engine stayed None forever, causing every download() call to raise
RuntimeError("_engine is not set") — silently failing and marking all
tracks not found.

All other streaming clients (Deezer, Qobuz, Tidal, HiFi, SoundCloud)
expose set_engine(); Amazon now matches the pattern.

Tests added: set_engine wires _engine, set_shutdown_check wires callback,
set_engine unblocks download dispatch (the exact live failure mode).

791e3630ff fix(amazon): wire amazon into all streaming-source guards
`validation.py` had amazon absent from `_streaming_sources`, causing
Amazon TrackResult objects (bitrate=None, size=0) to fall through to
the Soulseek P2P code path and get rejected by
`filter_results_by_quality_preference`. Every album track was marked
not found.

Fix: add 'amazon' to every streaming-source guard tuple/set that was
previously missing it:
- core/downloads/validation.py — primary bug fix (quality-filter bypass)
- core/downloads/status.py — _STREAMING_SOURCE_NAMES frozenset
- core/downloads/task_worker.py — hybrid fallback client map
- core/imports/side_effects.py — || filename→stream-id extraction
- web_server.py — is_streaming_source, transfer list display,
  candidate source label, _try_source_reuse, _store_batch_source
- tests/test_download_plugin_conformance.py — registry count + parametrize

Also updates the 2.5.3 What's New entry to drop the stale
"not yet wired" disclaimer.

d861a40277 Personalized pipeline: refresh snapshot on first-run too
Reproduced: selecting Fresh Tape (or any kind never generated before)
and running the pipeline silently skipped — UI showed
"No tracks in Fresh Tape — skipping sync" with no clue why.

Root cause: ensure_playlist auto-creates the playlist row on first
access with `track_count=0` and `last_generated_at=NULL`, but
`is_stale=0` by default (the column default — fresh rows aren't
"stale", they're "never generated"). Pipeline only refreshed when
`is_stale=True` OR `refresh_first=True`, so first-run rows fell
through both branches → read the empty snapshot → skip.

Fix: pipeline now also refreshes when `existing.last_generated_at is
None`. Same control flow, one extra condition:

    if refresh_first OR is_stale OR last_generated_at is None:
        refresh
    else:
        read existing snapshot

This is the right signal: "has the generator ever run for this row"
is exactly what `last_generated_at` tracks (the column is set in
`_persist_snapshot` after every successful refresh).

Stubs in test_handlers_personalized_pipeline.py updated to expose
`last_generated_at` on their SimpleNamespace returns so the new
attribute read doesn't AttributeError. Fresh stubs get a non-None
timestamp so they're treated as already-generated; the new test
`test_never_generated_snapshot_triggers_first_refresh` pins the
first-run-forces-refresh behavior with `last_generated_at=None`.

877d0e7d81 Personalized pipeline: auto-refresh stale snapshots after watchlist scan
Snapshots now track when their source data changes. Watchlist scan
emits stale flags on the playlists whose underlying pool just got
refreshed; the next pipeline run sees the flag and regenerates the
snapshot before syncing, so the server playlist never lags the source.

Schema:
- new `is_stale INTEGER NOT NULL DEFAULT 0` column on
  `personalized_playlists`, plus an idempotent ADD COLUMN migration
  in `ensure_personalized_schema` for installs created before this PR.
- `PlaylistRecord.is_stale: bool = False` exposed on the dataclass so
  callers can branch on freshness without re-querying.

Manager:
- new `mark_kinds_stale(kinds, profile_id=None)` flips the flag in
  bulk for a list of kinds (used by upstream data refreshers).
- `_persist_snapshot` clears `is_stale = 0` on successful refresh.
- SELECT statements + `_row_to_record` updated to read the column
  (with tuple-form length guard for safety).

Pipeline:
- `_build_payloads_for_kinds` now branches: refresh_first=True OR
  `existing.is_stale` -> refresh_playlist, else read existing
  snapshot. So the auto-refresh kicks in without needing the user to
  toggle the refresh-each-run option.

Watchlist scanner emits stale flags at three sites:
- after `update_discovery_pool_timestamp` -> marks pool-fed kinds
  stale: hidden_gems, discovery_shuffle, popular_picks, time_machine,
  genre_playlist, daily_mix.
- after release_radar `save_curated_playlist` -> marks `fresh_tape`.
- after discovery_weekly `save_curated_playlist` -> marks `archives`.

All three calls go through a module-level `_mark_personalized_kinds_stale`
helper that builds a PersonalizedPlaylistManager with `deps=None` (only
DB access is needed for the flag update — no generator dispatch). Each
call is wrapped in try/except so a flag failure can never abort the
scan itself.

Tests:
- new `TestStaleFlag` class in `test_personalized_manager.py` (6
  tests): default-false, single-kind flip, multi-kind, profile
  scoping, refresh-clears, empty-list noop.
- two new pipeline tests pin the auto-refresh dispatch:
  `test_stale_snapshot_auto_refreshes_even_without_refresh_first`
  and `test_non_stale_snapshot_skips_refresh`.
- existing stub-manager `SimpleNamespace` returns gained
  `is_stale=False` so the new attribute read doesn't AttributeError.

Full suite: 3391 pass.

User-facing WHATS_NEW entry added under 2.5.2 (above the prior
pipeline auto-sync entry) describing the auto-refresh behavior.

e1f0810df5 Personalized pipeline: UI multi-select picker for kinds + variants
The action was registered + the block declared, but the automation
builder's per-action config renderer didn't have a case for
`personalized_pipeline` so users only saw the bare card with the
generic delay-minutes input — no way to select which playlists to
sync. This commit adds the multi-select picker.

Backend:
- `core/personalized/api.list_kinds(manager=...)` now optionally
  takes a manager and includes the resolved variant list per kind
  (calls each spec's variant_resolver(deps) when present). Singleton
  kinds get an empty `variants` list. Variant-bearing kinds
  (time_machine / genre_playlist / daily_mix / seasonal_mix) get
  their full enumerated set.
- `web_server.py` `/api/personalized/kinds` route now passes a built
  manager so the variants list lands in the response.

Frontend:
- `webui/static/stats-automations.js` `_renderBlockConfigFields`
  gains a `personalized_pipeline` branch that renders a scrollable
  multi-select picker:
  - Singletons (Hidden Gems, Discovery Shuffle, Popular Picks,
    Fresh Tape, The Archives) = one checkbox row per kind
  - Variant kinds = a section header + one checkbox row per variant
    (e.g. Time Machine: 1960s/1970s/.../2020s; Seasonal: halloween/
    christmas/valentines/summer/spring/autumn)
  - Pre-checks rows that match the existing `kinds` config on edit
- New `_autoLoadPersonalizedKinds(slotKey)` fetches `/api/personalized/kinds`
  (cached after first load), renders the picker DOM, and pre-checks
  saved selections via `data-kind` / `data-variant` attributes on
  the checkboxes.
- `_renderBuilderCanvas` calls the loader for any `cfg-*-kinds-picker`
  it finds in the freshly-rendered slots.
- The save-time `_collectActionConfig` walks the picker's checked
  inputs (matched by `data-kind` attribute) and emits
  `{kinds: [{kind, variant?}, ...], refresh_first, skip_wishlist}`
  in the same shape the handler expects.

Tests:
- `tests/automation/test_automation_blocks.py::_FIELD_TYPES` adds
  'personalized_playlist_select' so the block-shape regression test
  accepts the new field type. (Test was failing because it whitelists
  every field type used across all blocks.)
- 189 automation + personalized API tests pass; full suite intact.

cc44254bf9 Personalized playlist pipeline: auto-sync discover-page playlists
Follow-up to the personalized-playlists standardization PR. New
`personalized_pipeline` automation action syncs selected discover-
page playlists (Hidden Gems / Discovery Shuffle / Time Machine /
Genre / Daily Mix / Fresh Tape / The Archives / Seasonal Mix) to
the active media server + queues missing tracks for download.

Same pattern as the existing mirrored `playlist_pipeline` but two
phases instead of four — no REFRESH (no external source to re-pull)
and no DISCOVER (manager-backed snapshots are already metadata-
matched). Pipeline shape:

    SNAPSHOT → SYNC → WISHLIST

Where SNAPSHOT either reads the persisted track list from
`PersonalizedPlaylistManager` (default) or refreshes it first when
`refresh_first=true` (cron use case: regenerate Hidden Gems nightly
and sync the fresh set).

Shared helper extraction:

PHASE 3 (SYNC loop) + PHASE 4 (WISHLIST tail) lifted out of mirrored
`playlist_pipeline` into `core/automation/handlers/_pipeline_shared.py`
as `run_sync_and_wishlist(deps, automation_id, playlists, sync_one_fn,
sync_id_for_fn, ...)`. Both pipelines call it. Mirrored injects
`auto_sync_playlist` as the per-playlist sync function; personalized
injects a thin wrapper that launches `_run_sync_task` directly with
a pre-built tracks_json. Same sync-state polling / progress emission
/ status counting / wishlist trigger logic — 0 duplication.

Files added:
- core/automation/handlers/_pipeline_shared.py
- core/automation/handlers/personalized_pipeline.py
- tests/automation/test_handlers_personalized_pipeline.py

Files changed:
- core/automation/handlers/playlist_pipeline.py: PHASE 3+4 replaced
  with shared helper call (~100 lines deleted, 1 helper invocation
  added; behavior identical).
- core/automation/deps.py: new `build_personalized_manager` field
  (lazy builder so the pipeline gets a fresh PersonalizedPlaylistManager
  per run).
- core/automation/handlers/__init__.py + registration.py: register
  `personalized_pipeline` action with the shared `pipeline_running`
  guard so it can't overlap mirrored.
- core/automation/blocks.py: new `personalized_pipeline` block
  declaration with config_fields (kinds multi-select, refresh_first,
  skip_wishlist).
- web_server.py: thread `_build_personalized_manager` into
  AutomationDeps construction.
- All 5 automation test fixtures: `_build_deps` adds
  `build_personalized_manager=lambda: None` stub.
- tests/automation/test_handler_registration.py:
  EXPECTED_ACTION_NAMES + EXPECTED_GUARDED_ACTIONS gain
  `personalized_pipeline`.

Trigger schema:

    {
      "_automation_id": "...",
      "kinds": [
        {"kind": "hidden_gems"},
        {"kind": "time_machine", "variant": "1980s"},
        {"kind": "seasonal_mix", "variant": "halloween"}
      ],
      "refresh_first": false,
      "skip_wishlist": false
    }

Tests (14 new, 178 automation total):
- _track_to_sync_shape: basic shape, source ID fallback chain,
  no-id returns empty string
- empty config / non-list kinds / empty kinds list all return
  error + clear pipeline_running flag
- _build_payloads_for_kinds: skips invalid entries, skips kinds
  with no tracks, refresh_first vs ensure dispatch, payload shape
  + sync_id format, manager exception swallowed continues
- _sync_personalized_playlist: launches background thread + returns
  status='started'
- happy path: stubbed sync_states drives helper to completion, flag
  cleaned up

Full suite: 3383 passed.

Note: the trigger UI block declares config_fields but the frontend
doesn't yet render the `personalized_playlist_select` multi-select
type — usable today via API; polished UI ships in a follow-up
frontend PR.

cc0828e9ff Personalized playlists (4/N): staleness post-filter (exclude_recent_days)
Adds the first quality feature on top of the manager: when
`config.exclude_recent_days > 0`, the manager drops any track from
the generator's output whose primary id was served by this kind
for this profile in the last N days.

Lives at the manager layer, not in each generator, so:
- generators stay focused on selection logic
- staleness behavior stays uniform across every kind
- enabling/disabling per playlist is just a config patch

Implementation:
- New `PersonalizedPlaylistManager._apply_quality_filters` runs after
  generator returns, before `_persist_snapshot`.
- Reads recent ids via existing `recent_track_ids` accessor.
- Tracks without a primary id pass through unchanged (nothing to
  dedupe on -- happens for sourceless tracks during edge cases).
- Returns a new list (never mutates input).

Default `exclude_recent_days = 0` preserves pre-overhaul behavior.
Per-playlist override via `PUT /api/personalized/playlist/<kind>/config`
with `{"exclude_recent_days": N}`. Recommended values:
- Discovery Shuffle: 1-3 days (high churn desired)
- Hidden Gems: 7-14 days (avoid same gems weekly)
- Time Machine / Genre: 30+ days (slow rotation OK, stable view preferred)

4 new boundary tests:
- Zero days = no filter (default behavior preserved)
- Positive days drops tracks served in window
- Filter preserves new tracks alongside dropped ones
- Tracks without primary id pass through unchanged

3369 tests pass total.

Note: listening-history cross-ref + seeded shuffle are deferred to
a future PR. Each requires deeper integration -- listening history
needs a play-events table the discovery pool can query against;
seeded shuffle needs the legacy generators to accept a seed param
without breaking their existing diversity / popularity logic.

9f383acbfb Personalized playlists (3/N): standardized API endpoints
Wraps the manager + generator dispatch behind one HTTP surface so
the UI can drop the patchwork `/api/discover/personalized/*` calls
in favor of a single REST shape. Legacy endpoints stay alive for
backward compat during the UI migration window.

New endpoints:
- GET    /api/personalized/kinds                                — list every registered kind + metadata
- GET    /api/personalized/playlists                            — list every persisted playlist for the active profile
- GET    /api/personalized/playlist/<kind>                       — fetch singleton + tracks
- GET    /api/personalized/playlist/<kind>/<variant>             — fetch variant + tracks
- POST   /api/personalized/playlist/<kind>/refresh               — regenerate singleton
- POST   /api/personalized/playlist/<kind>/<variant>/refresh     — regenerate variant
- PUT    /api/personalized/playlist/<kind>/config                — patch singleton config
- PUT    /api/personalized/playlist/<kind>/<variant>/config      — patch variant config

Per-call manager construction wires the deps each generator needs:
- database (MusicDatabase singleton)
- service (PersonalizedPlaylistsService for legacy generator calls)
- seasonal_service (SeasonalDiscoveryService for seasonal_mix)
- get_current_profile_id (active profile accessor)
- get_active_discovery_source (source dispatcher)

API handlers themselves live as pure functions in
`core/personalized/api.py` so they're testable without Flask. The
Flask layer in `web_server.py` is a thin parse-body / call-handler /
jsonify wrapper.

11 new boundary tests (122 personalized total):
- list_kinds enumerates registry, exposes default config + tags
- list_playlists returns empty list when none exist, serializes
  PlaylistRecord shape correctly
- get_playlist_with_tracks auto-creates on first access, returns
  persisted tracks, raises ValueError on unknown kind
- refresh_playlist runs generator and returns track snapshot,
  forwards config_overrides to the generator
- update_config patches stored config

3365 tests pass total. Manager construction triggers generator
registration via `from core.personalized import generators` import
side-effect.

53284ee7c8 Personalized playlists (2/N): all 8 generators wired through manager
Adds the per-kind generator modules and registers them with the
PlaylistKindRegistry so the manager's `refresh_playlist` can dispatch
to any of them.

Generators (each in its own module under
`core/personalized/generators/`):

Singletons (variant=''):
- hidden_gems       -> wraps service.get_hidden_gems
- discovery_shuffle -> wraps service.get_discovery_shuffle
- popular_picks    -> wraps service.get_popular_picks

Variant-bearing kinds:
- time_machine      -> variant = decade label ('1980s', '1990s', ...).
                       Variant resolver returns 7 standard decades.
                       Generator parses '1980s' -> 1980 + delegates
                       to service.get_decade_playlist.
- genre_playlist    -> variant = URL-safe genre key
                       ('electronic_dance', 'hip_hop_rap', ...).
                       Resolver normalizes parent-genre keys from
                       service.GENRE_MAPPING; free-form keywords
                       pass through to service.get_genre_playlist.
- daily_mix         -> variant = top-genre rank ('1' / '2' / '3' / '4').
                       Generator looks up user's Nth-ranked library
                       genre and returns discovery picks within it.
                       Library half (was a stub returning []) is
                       intentionally dropped: tracks table has no
                       source IDs, so library rows can't sync. Fixed
                       the stub to return [] cleanly without the
                       misleading log warning.
- fresh_tape        -> Spotify Release Radar. Reads curated track
                       IDs from discovery_curated_playlists (tries
                       'release_radar_<source>' first, falls back to
                       'release_radar') and hydrates against the
                       discovery pool.
- archives          -> Spotify Discover Weekly. Same hydration path
                       as fresh_tape but uses 'discovery_weekly'.
- seasonal_mix      -> variant = season key ('halloween' / 'christmas'
                       / 'valentines' / 'summer' / 'spring' / 'autumn').
                       Reads curated IDs via SeasonalDiscoveryService
                       then hydrates from seasonal_tracks (which
                       carries full track_data_json).

Each module:
- Defines `generate(deps, variant, config) -> List[Track]`.
- Defines `SPEC = PlaylistKindSpec(...)` and registers it on import
  (idempotent — re-import safe via `if registry.get(...) is None`).
- For variant-bearing kinds, also defines `variant_resolver(deps)`.

Shared helpers in `_common.py`:
- `get_service(deps)` pulls the legacy
  `PersonalizedPlaylistsService` instance (deps.service or
  deps['service']).
- `coerce_tracks(rows)` runs each dict through `Track.from_dict`,
  tolerates None / non-list inputs.

Tests (50 new, total 85 across personalized subsystem):
- Singletons: registration + display name + dispatch + limit
  forwarding + empty/None tolerance + missing-deps error +
  dict-form deps acceptance (16 tests).
- Variants: variant_resolver listing + label parsing + invalid
  variant errors + parent-key normalization + free-form passthrough
  (13 tests).
- Curated/hybrid: daily_mix rank-to-genre resolution + rank-out-of-
  range empty + invalid-variant error; fresh_tape & archives
  hydration order + missing-id skip + source-specific-then-fallback
  key dispatch + limit + missing-database-dep error; seasonal_mix
  curated-id hydration order + missing-id skip + JSON round-trip +
  empty-curated empty + limit + missing-service error (21 tests).

3304+ tests pass. No regression on existing 62 personalized tests.

79224ed294 Personalized playlists (1/N): unified storage + manager foundation
Begins the standardization of the personalized-playlist subsystem.
Pre-existing state was a patchwork: Group A (Fresh Tape / Archives /
Seasonal Mix) lived in `discovery_curated_playlists` and
`curated_seasonal_playlists` with inconsistent shapes; Group B
(Hidden Gems / Discovery Shuffle / Time Machine / Popular Picks /
Genre / Daily Mixes) was computed on-demand by
`PersonalizedPlaylistsService` with no persistence -- every call
reran the generator with `ORDER BY RANDOM()` so results rotated.

Post-overhaul (this PR) every personalized playlist lands in one
unified storage layer with stable identity, persistent track lists,
explicit refresh, and per-playlist user-tweakable config.

Foundation in this commit (no behavior change yet):

- `database/personalized_schema.py`: 3 tables created idempotently
  at app startup (wired into `MusicDatabase._initialize_database`).
  - `personalized_playlists`: one row per (profile, kind, variant)
    with config_json, track_count, last_generated_at,
    last_synced_at, last_generation_source, last_generation_error.
    Variant '' (empty string) for singletons; non-empty for
    time_machine / seasonal_mix / genre_playlist / daily_mix.
  - `personalized_playlist_tracks`: current snapshot per playlist.
    Atomically replaced on refresh.
  - `personalized_track_history`: append-only log powering the
    `exclude_recent_days` config knob.

- `core/personalized/types.py`: `Track`, `PlaylistConfig`,
  `PlaylistRecord` dataclasses. `PlaylistConfig.merged()` for
  partial-update PATCH semantics; `Track.from_dict()` accepts the
  legacy generator output shape unchanged.

- `core/personalized/specs.py`: `PlaylistKindSpec` (kind,
  name_template, default_config, generator, variant_resolver) and a
  module-level registry. Generators register at import time;
  manager dispatches by kind.

- `core/personalized/manager.py`: `PersonalizedPlaylistManager` --
  the only thing that touches the new tables. Owns:
  - ensure_playlist (auto-create row from kind defaults)
  - get_playlist / list_playlists
  - refresh_playlist (atomic snapshot replace; generator exception
    preserves previous good snapshot + records error on row)
  - get_playlist_tracks
  - update_config (deep-merge with stored config, including extra dict)
  - recent_track_ids (staleness lookup for generators)

35 boundary tests in `tests/test_personalized_manager.py` pin every
shape: config round-trip / merge semantics / extra deep-merge /
defaults; Track.from_dict tolerance + primary_id fallback chain;
registry dedup / display_name with+without variant; manager
ensure_playlist auto-create + idempotency, variant separation,
required-variant enforcement, unknown-kind error; refresh persists
+ replaces atomically + survives generator exception with previous
snapshot intact + records source from first track + round-trips
nested track_data_json; update_config patch semantics; list_playlists
profile scoping; staleness history scoped to (profile, kind, days).

3304 tests pass total. Generators ship in subsequent commits on this
branch -- each kind migrated one at a time with its own per-kind
boundary tests.

d3768610d7 Extract automation handlers (kettui-bar): engine-boundary tests
Per-handler boundary tests pin each handler's body in isolation.
Adding engine-boundary tests that pin the REGISTRATION layer:
- every expected action name registered, no drops, no extras
- guarded actions register a guard, unguarded ones don't
- every registered handler is callable
- every guard returns a bool
- all four progress callbacks registered in the right slots
- progress_init / progress_finish / record_history / on_library_scan_completed
  are invocable through the engine's stored callable shape (not just
  the bare extracted function)
- finish callback respects _manages_own_progress flag at the engine
  boundary too
- library_scan_completed wiring registers a callback on the scan
  manager and that callback fires engine.emit when invoked
- every handler returns a `{'status': ...}` dict on a minimal config
  trigger -- proves no handler raises into the engine, even when its
  guard / short-circuit / error path is the one taken

Uses a minimal _RecordingEngine that captures registrations + a
_RecordingScanMgr that captures completion callbacks. No real
AutomationEngine, no real Flask app, no real DB. The kettui standard
for refactor PRs: don't ship "behavior preserved" claim that's only
validated at the function boundary -- exercise the engine seam too.

EXPECTED_ACTION_NAMES + EXPECTED_GUARDED_ACTIONS frozen sets at the
top: any future drift (rename / drop / add a handler / change which
ones are guarded) fails this test immediately so refactor PRs can't
quietly mutate the registration shape.

13 new tests, 164 automation tests pass total.

e140da117a Extract automation handlers (4/3 — finish): progress callbacks + scan-completion emitter
Cleans up the four remaining inline callbacks at the bottom of
`web_server._register_automation_handlers` so the function is now
purely deps-construction + register_all + a logger.info line.

Lifted:
- `_progress_init`, `_progress_finish`, `_record_automation_history`,
  and `_on_library_scan_completed` -> core/automation/handlers/progress_callbacks.py

Each is a top-level function that takes deps as a parameter; the
engine sees thin lambdas through `register_progress_callbacks` /
`register_library_scan_completed_emitter` (called from `register_all`).

Two new deps fields:
- `init_automation_progress` (delegates into the live progress tracker)
- `record_progress_history` (delegates into _auto_progress.record_history)

12 new boundary tests in tests/automation/test_progress_callbacks.py
pin every shape:
- progress_init forwards to init_automation_progress
- progress_finish skips when handler manages its own progress
  (prevents double-emit of finished status)
- progress_finish: completed -> finished/Complete/success;
  error -> error/Error/error; msg falls through error -> reason ->
  status -> 'done'
- record_history threads the live db into the recorder
- on_library_scan_completed: no engine = noop, server type taken
  from web_scan_manager._current_server_type, defaults to 'unknown'
- register_library_scan_completed_emitter: no scan manager = noop,
  registered callback emits the right event when invoked

3256 tests pass, no regression.

Final state of `_register_automation_handlers`:
- Was: 1530 lines, 21 nested closures + 4 progress callbacks
- Now: ~50 lines, builds AutomationDeps and calls register_all

web_server.py: 34,220 -> 34,187 lines (-33 net, -1,406 across the
whole branch).

017553193f Extract automation handlers (3/3): maintenance + misc, finishing the lift
Final commit of the automation-handler refactor. With this commit
every closure that used to live in
`web_server._register_automation_handlers` is now a top-level
function in `core/automation/handlers/`.

Handlers extracted in this commit:

- start_database_update + deep_scan_library
    -> core/automation/handlers/database_update.py
    Both share the db_update_state monitoring pattern (poll until
    status flips, stall detection emits warning at 10 min, 2-hour
    outer timeout). Lifted into a shared `_run_with_progress` helper
    inside the module so the per-handler bodies stay tiny.

- run_duplicate_cleaner -> core/automation/handlers/duplicate_cleaner.py
- start_quality_scan    -> core/automation/handlers/quality_scanner.py

- clear_quarantine, cleanup_wishlist, update_discovery_pool,
  backup_database, refresh_beatport_cache
    -> core/automation/handlers/maintenance.py
    Grouped because each body is short (~20-50 lines) and they share
    no state — splitting into per-handler files would just add import
    noise.

- clean_search_history, clean_completed_downloads, full_cleanup
    -> core/automation/handlers/download_cleanup.py
    Grouped because all three reach the download orchestrator,
    tasks_lock, and download_batches/download_tasks accessors. The
    full_cleanup multi-step orchestration shares phase-detection
    logic with clean_completed_downloads.

- run_script         -> core/automation/handlers/run_script.py
- search_and_download -> core/automation/handlers/search_and_download.py

`AutomationDeps` grew with the new dependency surface:
- get_db_update_state + db_update_lock + db_update_executor +
  run_db_update_task + run_deep_scan_task
- get_duplicate_cleaner_state + duplicate_cleaner_lock +
  duplicate_cleaner_executor + run_duplicate_cleaner
- get_quality_scanner_state + quality_scanner_lock +
  quality_scanner_executor + run_quality_scanner
- download_orchestrator + run_async + tasks_lock +
  get_download_batches + get_download_tasks +
  sweep_empty_download_directories + get_staging_path
- docker_resolve_path + get_current_profile_id +
  get_watchlist_scanner + get_app + get_beatport_data_cache
- set_db_update_automation_id (writes the legacy global so the live
  DB-update progress callbacks still living in web_server.py keep
  emitting against the active automation card)

`web_server._register_automation_handlers` is now ~50 lines: build
deps once, call register_all. The 667-line block of remaining
closure definitions and engine register calls is gone.

The final orphan was the `_db_update_automation_id` module global —
the DB-update progress callbacks at line ~14080 still read it
directly, so the extracted database_update handler propagates the
automation id through `deps.set_db_update_automation_id` (a closure
in web_server that writes the global). When the legacy callbacks
get extracted in a future PR the setter goes away.

Tests:
- tests/automation/test_handlers_maintenance.py adds 21 boundary
  tests covering every newly-extracted handler shape: guard
  short-circuits (already-running returns skipped), deps wiring
  (set_db_update_automation_id called with the right id),
  exception swallow contract, status returns, path-traversal
  blocked in run_script, source-mode skip in clean_search_history,
  active-batch skip in clean_completed_downloads, etc.
- 3244 tests pass (was 3223 — 21 new), no regression.

web_server.py: 35,593 -> 34,220 lines (-1,373 net across 3 commits).
Issue #1 from the extraction punch list is now COMPLETE.

cde237c7e7 Extract automation handlers (2/N): playlist lifecycle group
Continues the lift from `web_server._register_automation_handlers`.
This commit extracts the four playlist-lifecycle closures:

- `refresh_mirrored`   -> core/automation/handlers/refresh_mirrored.py
- `sync_playlist`      -> core/automation/handlers/sync_playlist.py
- `discover_playlist`  -> core/automation/handlers/discover_playlist.py
- `playlist_pipeline`  -> core/automation/handlers/playlist_pipeline.py

The pipeline composes refresh + sync + discover, so all four ship
together. The pipeline imports the other three handler modules
directly (cross-handler call) instead of going through the engine,
preserving the "single trigger from the user's perspective" UX.

`AutomationDeps` grew to cover the new dependency surface:
- run_playlist_discovery_worker, run_sync_task, load_sync_status_file
  (pre-existing background-task entry points)
- get_deezer_client, parse_youtube_playlist (per-source clients)
- get_sync_states (live mutable accessor for the sync UI's state dict)

`web_server._register_automation_handlers` now wires those plus the
existing infrastructure into a single `AutomationDeps` and calls
`register_all`. The 669-line block of closure definitions and engine
register calls (lines 959-1627 pre-edit) is gone -- the file shed
743 lines net on this commit.

`tests/automation/test_handlers_playlist.py` adds 17 new boundary
tests:
- discover_playlist: no_id error, specific_id starts worker, all=True
  enumerates, no playlists in db
- refresh_mirrored: error path, source filter (file/beatport excluded),
  Spotify happy path with auto-discovered marker, per-playlist
  exception captured into errors counter
- sync_playlist: no_id, not_found, no_tracks, no-discovered-tracks
  skip, discovered-track happy path, unchanged-since-last-sync skip
- playlist_pipeline: no_playlist clears running flag, no-refreshable
  clears running flag, exception clears running flag

3223 tests pass. web_server.py: 35,593 -> 34,850 lines (743 removed).

ea7d5c65bb Extract automation handlers (1/N): infrastructure + 3 simple handlers
Begins the lift of `web_server._register_automation_handlers` (1530
lines, 20 nested closures) into `core/automation/handlers/`. Each
extracted handler is a top-level function that accepts
`(config, deps)` instead of reaching for module-level globals --
makes them unit-testable in isolation.

Infrastructure:
- `core/automation/deps.py`: `AutomationDeps` (dependency-injection
  bundle of clients + callables) and `AutomationState` (mutable flags
  shared across handler invocations, with thread-safe accessors).
- `core/automation/handlers/__init__.py` + `registration.py`: one-stop
  `register_all(deps)` that wires every extracted handler to the
  engine.

First batch of handlers extracted:
- `process_wishlist` -> `core/automation/handlers/process_wishlist.py`
- `scan_watchlist`   -> `core/automation/handlers/scan_watchlist.py`
- `scan_library`     -> `core/automation/handlers/scan_library.py`

`web_server._register_automation_handlers` now builds the deps once
and calls `register_all(deps)` for the extracted batch. Remaining
17 closures still live below; subsequent commits in this branch
finish the lift.

14 boundary tests in `tests/automation/test_handlers_simple.py` pin
every shape: success path, exception swallow contract, fresh-vs-stale
state detection (scan_watchlist's id() trick), guard short-circuits,
state cleanup on exceptions, AutomationState concurrent-safe accessors.
All 101 automation tests pass; no regression.

b42cafa150 AcoustID + quarantine modal: three bug fixes (closes #607, closes #608)
Issue #607 (AfonsoG6) -- two AcoustID problems:

1. Live recordings false-quarantining as "Version mismatch: expected
   '... (Live at Venue)' (live) but file is '...' (original)" because
   MusicBrainz often stores the recording entity with a bare title --
   the venue / live annotation lives on the release entity, not the
   recording. The audio fingerprint correctly identifies the live
   recording, but the title-text comparison flagged it as wrong.

   New pure helper `core/matching/version_mismatch.py:is_acceptable_version_mismatch`
   accepts the mismatch only when:
     - One-sided AND involves 'live': exactly one side is 'live' and
       the other is bare 'original'. Two-sided mismatches stay strict.
     - Fingerprint score >= 0.85 (stricter than the existing 0.80
       minimum -- escape valve only fires when AcoustID is more
       confident than its own threshold).
     - Bare title similarity >= 0.70.
     - Artist similarity >= 0.60.

   Other version markers (instrumental, remix, acoustic, demo, etc)
   stay strict -- those have distinct fingerprints AND MB always
   annotates them in the recording title. The existing
   test_acoustid_version_mismatch.py suite passes unchanged.

2. Audio-mismatch failure message reported "identified as '' by ''
   (artist=100%)" when AcoustID returned multiple recordings -- prior
   code mixed `recordings[0]`'s strings (which can be empty) with
   `best_rec`'s scores. Now uses `matched_title` / `matched_artist`
   consistently in both the high-confidence-skip path and the final
   fail message.

Issue #608 (AfonsoG6) -- quarantine modal:

3. Approve / Delete buttons silently no-op'd when the filename
   contained an apostrophe -- the unescaped quote broke the inline JS
   in the onclick handler. Now wraps the id via
   `escapeHtml(JSON.stringify(id))`, which round-trips quotes /
   backslashes / unicode / newlines safely through the HTML attribute
   to JS string boundary.

4. Bonus UX: quarantine entry expanded view now shows source uploader
   (username) and original soulseek filename when the sidecar carries
   that context -- helps trace which uploader the bad file came from.
   Backend exposes `source_username` + `source_filename` fields from
   `sidecar.context.original_search_result`. Degrades to '' on legacy
   thin sidecars.

Tests:
- 23 new boundary tests in tests/matching/test_version_mismatch.py
  pin every shape: equal versions trivial, one-sided live both
  directions, threshold floors (each just below default -> reject),
  two-sided strict, non-live one-sided strict (covers exact
  test_instrumental_returned_for_vocal_request_fails scenario),
  custom-threshold overrides.
- 4 existing test_acoustid_version_mismatch.py tests pass unchanged.
- 507 AcoustID / matching / imports tests pass.

b05ba5d498 Reorganize: optional embedded-tag mode (closes #592)
Adds an opt-in alternative metadata source for reorganize. The
existing API path (query Spotify / iTunes / Deezer / Discogs /
Hydrabase for the canonical tracklist) stays the default and is
unchanged. The new tag mode reads each file's embedded tags as the
source of truth instead -- useful for well-enriched libraries where
API drift can produce inconsistent renames, and avoids API calls
entirely.

- New pure helper `core/library/reorganize_tag_source.py` adapts the
  output of `read_embedded_tags` (the same mutagen path the audit-
  trail modal uses) to the `api_album` / `api_track` shapes that
  `_build_post_process_context` already consumes. Handles ID3-style
  "5/12" track + disc shapes, multi-value Artists tags, year
  normalization across 5 date formats, releasetype canonical tokens,
  multi-artist string splits across 9 separators.
- `plan_album_reorganize` accepts `metadata_source: 'api' | 'tags'`
  (default 'api') and `resolve_file_path_fn`. Tag mode branches into
  a new `_plan_from_tags` that reads each track's file and produces
  per-item `api_album` + `api_track` instead of a shared one.
- `_run_post_process_for_track` accepts a per-item `api_album`
  override so each file's own album metadata flows through post-
  process (not a single shared dict).
- `total_discs` in tag mode honors the `totaldiscs` tag and the
  trailing `/N` of an ID3 `discnumber = "1/2"`. Partial-album
  reorganize still routes into the correct `Disc N/` subfolder when
  the tag knows the total even if not all discs are present locally.
- Bare `discnumber = "1"` no longer poisons `total_discs` -- it
  carries no total signal.
- `reorganize_album` surfaces a tag-mode-specific error when no
  files are readable, instead of the API-mode "run enrichment first"
  message which would mislead in tag mode.
- `QueueItem.metadata_source` field, `enqueue` / `enqueue_many`
  pass-through, runner injects `item.metadata_source` into
  `reorganize_album`.
- `web_server.py` endpoints accept `mode` body param. Falls back to
  the `library.reorganize_metadata_source` config setting, then to
  'api'. Strict allowlist (api / tags) -- anything else falls back.
- Frontend: per-album modal + reorganize-all modal both grow a new
  "Metadata Mode" dropdown above the source picker. Tag mode hides
  the source picker (irrelevant). Choice persisted in localStorage.
  Both preview + execute fetches send `mode` in body.

Tests:
- 49 boundary tests on the pure helper pin every shape: ID3 "5/12",
  multi-artist split, year normalization, releasetype validation,
  total_discs precedence, defensive paths.
- 6 planner-level integration tests pin the wiring: tag-mode with
  good tags, partial-disc with totaldiscs tag, file missing,
  some-match-some-fail, defensive resolve_file_path_fn=None,
  API-mode regression guard.
- All 3171 tests pass; 52 existing reorganize tests unchanged.

2f284efa57 Retag now re-embeds LYRICS tag instead of leaving it empty
Discord report (netti93). The download flow runs `enhance_file_metadata`
(clears all tags) then `generate_lrc_file` (writes .lrc sidecar AND
embeds USLT). The retag flow only ran the first half — `enhance_file_metadata`
cleared USLT and there was no follow-up to restore it.

Two coordinated fixes (no new setting per kettui scope discipline —
user described it as "might even be an idea," consistency was the
load-bearing ask).

Fix 1 — retag calls generate_lrc_file after enhance

`core/library/retag.py:execute_retag` now invokes
`deps.generate_lrc_file` right after the `enhance_file_metadata`
call, mirroring the download pipeline. New `generate_lrc_file`
field on `RetagDeps`, defaults to None for backward compat with
any test caller that builds RetagDeps without it. Web_server's
`_build_retag_deps()` factory wires in the real
`core.metadata.lyrics.generate_lrc_file`.

Placement matters — runs BEFORE `safe_move_file` so the helper
sees the audio file at its current path with its existing sidecar
(which retag hasn't moved yet). After the embed, the audio file
gets moved with USLT now present; the sidecar move step that
follows is unaffected.

Fix 2 — create_lrc_file re-embeds from existing sidecar

`core/lyrics_client.py:create_lrc_file` used to early-return True
when an .lrc / .txt sidecar already existed (skipping the LRClib
fetch). For the retag case the sidecar is already there, so the
shortcut hit and USLT was never re-written. Now the helper reads
the existing sidecar and calls `_embed_lyrics` with its content
before returning. Empty / unreadable sidecars short-circuit
silently — defensive, no crash. Download flow unaffected because
no sidecar exists at fetch time.

7 boundary tests pin: existing .lrc triggers re-embed, existing
.txt triggers re-embed, empty sidecar skips embed, unreadable
sidecar swallows error, no sidecar falls through to LRClib (download
path regression guard), RetagDeps.generate_lrc_file field accepted,
field optional for backward compat.

Full suite: 3120 passed.

30f017d1f0 Stop writing TRCK as "6/0" when album total_tracks is unknown
Discord report (netti93): downloaded album tracks were tagged with
TRCK = "6/0" instead of "6/13" when source data was incomplete. The
retag tool wrote correct "6/13" because core/tag_writer.py already
handled the case.

Trace: core/metadata/enrichment.py:105 formatted unconditionally as
f"{track_number}/{total_tracks}" and many album-dict construction
sites pass total_tracks: 0 (per types.py, 0 means "unknown" — not a
real count). That 0 propagated straight to disk.

Fix at the consumer boundary so every album-dict constructor stays
unchanged. Lifted to pure helper
core/metadata/track_number_format.py:format_track_number_tag that
drops the /N suffix when total is 0 / None / negative — emits just
"6" instead. Matches retag's behavior + ID3 spec convention (TRCK
can be "N" or "N/M"). MP4 trkn tuple gets the same treatment via
format_track_number_tuple returning (6, 0) per spec's "unknown
total" marker.

Wired into all three format-write sites in enrichment.py: ID3 (TRCK),
Vorbis (tracknumber), MP4 (trkn). When source data has correct
total_tracks (album downloads via the metadata-source pipeline,
retag flow), behavior unchanged — still writes "6/13".

16 boundary tests pin every shape: known total / zero total / none
total / none track / zero track / negative inputs / string coercion
/ unparseable strings / floats truncate.

Full suite: 3113 passed.

9cc09118bf AcoustID scanner: multi-candidate match + duration guard + multi-value retag
Closes #587. Three coordinated fixes per codex's diagnosis. AcoustID
verification gate left intact — these fixes target the upstream
scanner false-positive surface plus a separate retag-path gap.

Bug 1 — scanner used recordings[0] as authoritative

`core/repair_jobs/acoustid_scanner.py:_scan_file` only checked the
top fingerprint match's metadata. AcoustID often returns multiple
recordings per fingerprint (sample collisions, multi-MB-record
cases) and the wrong-credited recording can outrank the right-
credited one. Foxxify case 2 (Nana / Nana): top match credited the
wrong artist while a lower-ranked candidate matched the user's
expected metadata exactly.

Lifted the verifier's all-candidates check to a shared pure helper
`core/matching/acoustid_candidates.py:find_matching_recording`. Both
verifier and scanner can now ask "given these candidates, does ANY
of them match expected (title, artist)?" with the same contract.
Scanner suppresses the finding when any candidate matches.

Bug 2 — no duration check guards against fingerprint hash collisions

Foxxify case 3: 17-minute mashup edit fingerprinted to a 5-minute
late-70s Japanese hiphop track (different songs, fingerprint hash
collision on a sampled section). Scanner had no signal to detect
this and would have recommended retagging the 17-min file as the
5-min track.

`duration_mismatches_strongly` in the same helper module flags drifts
beyond max(60s, 35%). Scanner now skips findings when the candidate's
duration disagrees strongly with the file's expected duration. Loaded
duration via the existing tracks SQL (added `t.duration` to the
SELECT). Returns False when either side is unknown — no behavior
change for older rows without duration data.

Bug 3 — scanner retag bypassed multi-value ARTISTS tag setting

`core/repair_worker.py:_fix_wrong_song` called `write_tags_to_file`
with single-string artist updates. The writer only wrote TPE1
(single string) and never read the user's
`metadata_enhancement.tags.write_multi_artist` config. Multi-value
ARTISTS tags got stripped on every retag, contradicting the
post-download enrichment pipeline's behavior.

Per codex's pick (option B over routing through enhance_file_metadata),
extended `write_tags_to_file` with an optional `artists_list`
parameter. Each format-specific writer respects the config flag the
same way enrichment.py does:
- ID3: TPE1 stays as joined display string + TXXX:Artists multi-value
- Vorbis/Opus/FLAC: `artist` display string + `artists` multi-value key
- MP4: \xa9ART as list when on, single string when off

Scanner retag derives the per-artist list by splitting AcoustID's
credit through the existing `split_artist_credit` helper (same
separators the matching layer already uses).

Backward compatible: callers that don't pass `artists_list` get the
exact same single-string write as before. No regression for the
write_artist_image button or any other tag_writer caller.

15 tests on the candidate helper + duration guard.
13 tests on the tag_writer multi-value path (write/skip/single/
no-list cases for FLAC + the config-gate helper).
4 new scanner regression tests pinning lower-ranked candidate
suppression, no-suppression when no candidate matches, duration
mismatch skip, no-skip when duration matches.

Existing scanner tests updated for the new 11-column SQL select
(added duration column to fake schema + test row tuples).

Full suite: 3097 passed. Ruff clean.

0aa18b0180 Cross-script artist aliases: include canonical name + non-strict fallback
Closes #586. Follow-up to #442 — Cyrillic / kanji canonical names
weren't bridging cross-script comparisons. Reporter case: "Dmitry
Yablonsky" tracks quarantined as audio mismatch with file identified
as "Русская филармония, Дмитрий Яблонский" (4% artist sim) even
though the Cyrillic spelling is just the Russian transliteration.

Codex diagnosed three layered bugs in the alias resolution chain.
This fixes all three.

Bug 1 — fetch_artist_aliases ignores canonical name + sort-name

`core/musicbrainz_service.py:fetch_artist_aliases` only read
`data['aliases']`. For artists where MB's canonical `name` IS the
cross-script form (and the Latin spelling lives only in aliases —
or vice versa), the missing direction never made it into the
returned list. Fix: include both `data['name']` and `data['sort-name']`
alongside the explicit alias entries (deduped, also pulls each
alias entry's sort-name when present).

Bug 2 — lookup_artist_aliases ran search in strict mode only

Strict mode queries `artist:"..."` only and skips MB's alias and
sortname indexes. Cross-script searches found nothing under strict
because the user's Latin input never matches a Cyrillic canonical
name in the artist index. Fix: lifted the search-and-score logic
to a private helper `_search_and_score_artists(name, strict=)` and
fall back to non-strict when strict returns empty OR all results
fail the trust gate. Non-strict (bare query) hits all indexes.

Bug 3 — trust gate weighted local similarity 70%

Combined score = local_sim * 0.7 + mb_score/100 * 0.3. Cross-script
pairs have local sim ~0 → combined ~0.30 → below the 0.85 threshold
→ cached as empty even when MB's own confidence was 100. Fix: added
an MB-only escape — when MB score is >= 95 AND the result is
unambiguous (top result's MB score leads the runner-up by >= 5),
accept regardless of local similarity. The existing combined-score
path stays intact for same-script matches (#442 Hiroyuki Sawano
case still passes via that path).

12 new tests pin every layer:
- fetch_artist_aliases canonical-name inclusion + dedup against
  alias entries + missing-canonical handling + exception path
- strict-then-non-strict fallback (empty-strict + low-strict-score)
- trust gate MB-only escape + low-confidence rejection + ambiguity
  rejection (two artists same MB score) + same-script regression
- end-to-end reporter scenario with the real `artist_names_match`
  helper proving the bridge works for "Русская филармония, Дмитрий
  Яблонский" vs expected "Dmitry Yablonsky"

Existing alias tests in `test_artist_alias_service.py` updated to
reflect: canonical name now appears in `fetch_artist_aliases`
output, lookup makes 2 search calls (strict + non-strict fallback)
on first cache miss instead of 1.

e7ecaca3fd Fix MTV Unplugged & live-album false-quarantine pipeline
Closes #589. Tracks from MTV Unplugged / Live At / unplugged albums
consistently failed AcoustID verification with "Version mismatch:
expected (live) but file is (original)". Two upstream bugs fed into
the false positive — the AcoustID gate itself was correctly catching
the wrong file Tidal had selected. Codex diagnosed all three layers,
this fixes the two upstream causes and leaves the verifier alone.

Bug 1 — album-scoped library check false-misses owned albums

`core/downloads/master.py:184` scored "Shy Away (MTV Unplugged Live)"
(source title from playlist) vs "Shy Away" (local DB stored title)
with raw string similarity. Massive length asymmetry → ~0.3 → below
the 0.7 threshold → marked missing. Combined with the
`allow_duplicates and batch_is_album` short-circuit that disables
the global fallback for album downloads, the user's already-owned
album re-triggered every track for download. Explains the screenshot
showing "0 found / 7 missing" on an album the user manually placed.

New pure helper `core/matching/album_context_title.py:strip_redundant_album_suffix`
strips trailing parenthetical / bracket / dash suffixes whose tokens
are fully subsumed by the album context — at least one version
marker (live / unplugged / acoustic / session / concert / tour)
overlapping with the album, and every other token is either a
known marker, a year, a tolerated noise word, or a word from the
album title. Album-context-implied "live" added when the album
mentions unplugged / concert / tour / session.

Wired into the album-confirmed scope ONLY (not global matching).
Compares both raw and normalized source titles per album track and
takes the max similarity, so the helper returning the input
unchanged (when album doesn't imply version context) preserves
the pre-fix behavior.

Bug 2 — Tidal qualifier filter only ran on fallback searches

`core/tidal_download_client.py:345` set `is_fallback = attempt_idx > 0`
and only filtered when `is_fallback and required_qualifiers`. Primary
search returned all results unfiltered, so a query for "Shy Away
(MTV Unplugged Live)" could accept the studio cut if Tidal happened
to rank it first. Now the qualifier filter applies to BOTH primary
and fallback search attempts — log message updated to indicate
which path triggered.

Bug 3 — qualifier check ignored album.name

The legacy `_track_name_contains_qualifiers` only inspected the
track name. For concert / unplugged releases the live signal
typically lives in the album title, not the track title. New
`_track_matches_qualifiers` accepts a track object and inspects
both `track.name` AND `track.album.name`. Legacy helper preserved
to keep its existing test contract.

AcoustID version-mismatch gate at core/acoustid_verification.py
left intact — it correctly catches genuinely-wrong files that slip
through upstream filters. The In My Feelings (Instrumental) test
that pins this behavior continues to pass.

19 tests on the album-context helper covering MTV Unplugged
variants, dash/parens/brackets suffix shapes, year tolerance,
plural-form markers, the implied-live set, anti-regression cases
(instrumental/remix on a studio album must NOT be stripped),
empty/none defensive paths.

13 tests on the Tidal qualifier helper covering legacy
track-name-only behavior preserved, qualifier in track name alone,
qualifier in album name alone (the MTV Unplugged scenario),
multi-qualifier requirements, no-qualifiers always passes,
defensive against missing track.album, word-boundary avoiding
substring false-matches, _extract_qualifiers picking up live +
unplugged from the user's exact reporter query.

c9d4b02a02 Fix Deezer contributors tagging silently dropping for cache-polluted tracks
Closes #588. Contributing-artist tagging worked for some tracks but
silently dropped them for others — most reproducibly when the album
had been fetched before the per-track post-process ran.

Trace: get_track_details cache check used `track_position in cached`
as the "full payload" sentinel. Both `/track/<id>` AND
`/album/<id>/tracks` set track_position. Only `/track/<id>` sets the
`contributors` array. When album-tracks data hit the cache first,
get_track_details returned the partial record →
_build_enhanced_track found no contributors → metadata-source
contributors-upgrade silently fell back to single-artist.

Reporter's case (Andrea Botez - Sacrifice): the album fetch logged
"Retrieved 4 tracks for album 673558211" before the post-process,
which cached all 4 tracks as partial records. The contributors-
upgrade then hit the partial cache and the upgrade log line never
fired because len(upgraded) was never > 1.

Lifted cache-validity to a pure helper `_is_full_track_payload` that
requires BOTH `track_position` AND `contributors` key presence. Empty
list `[]` is valid — single-artist tracks fetched via `/track/<id>`
carry it explicitly. Partial cache hits fall through to a fresh
`/track/<id>` fetch, which writes the full payload back to cache.

11 boundary tests pin every shape: full payload, single-artist with
empty contributors list, partial album-tracks shape, search-result
shape, none/non-dict, and the cache-hit/cache-miss/api-failure paths
on get_track_details (including the exact reporter-scenario
regression).

083355ec8c Persist Find & Add selections as permanent server-playlist match overrides
Closes #585. When a Spotify source track had a versioned suffix not
present in the local file ("Iron Man - 2012 - Remaster" vs "Iron Man"),
the auto-matcher missed the pair. User could click Find & Add to pick
the right local file — that worked, file got added to the Plex
playlist — but the source track stayed in Missing while the added
file appeared in Extra, because the matcher kept no record of the
user-confirmed pairing. On the next sync the source track re-tried
to download.

Fix: every Find & Add selection now writes a (spotify_track_id →
server_track_id) override into sync_match_cache at confidence=1.0.
The matching algorithm runs an override pass BEFORE the existing
exact and fuzzy passes, so any user-confirmed pair short-circuits
straight to "matched" without going through title normalization.
Covers every mismatch class — dash-suffix remasters, covers /
karaoke, alt masters, cross-language titles, typo'd local files.

- core/sync/match_overrides.py (new) — pure helpers
  resolve_match_overrides + record_manual_match. 18 boundary tests
  pin: cache hits, cache misses falling through to normal matching,
  stale-cache (server track removed) handled gracefully, str/int
  id coercion, partial cache hits, defensive against non-dict
  inputs and DB exceptions.
- web_server.py — get_server_playlist_tracks runs the override
  pre-pass before exact/fuzzy matching. server_playlist_add_track
  accepts source_track_id + source_title + source_artist and
  persists the override after every successful add (Plex / Jellyfin
  / Navidrome). source_track_id added to source_tracks payload so
  the frontend has it.
- webui/static/pages-extra.js — _serverSelectTrack sends
  source_track_id + source_title + source_artist when adding a
  track from a mirrored playlist context.
- Sync match cache schema unchanged — already had UNIQUE
  (spotify_track_id, server_source) which fits the override
  semantics perfectly. Manual overrides distinguished from
  auto-discovered matches by confidence=1.0.

f4cff78f13 Quarantine management — list, approve, delete, recover
Closes #584. Quarantined files used to sit in ss_quarantine/ with a
thin sidecar — no UI, no recovery, no way to see what got dropped.
This adds the management surface the user needs without going to the
filesystem.

UI: new "Quarantine" button on the downloads page header opens a
modal with every quarantined file (filename, expected track/artist,
reason, when, size). Three actions per row:

- Approve (one-click): restores the file, re-runs the post-process
  pipeline with ONLY the failing check skipped, lands in the library
  with full tags + lyrics + scan
- Recover (legacy fallback): moves to Staging for thin-sidecar
  entries that lack the embedded context Approve needs
- Delete: permanent removal of file + sidecar

Per-check bypass: context['_skip_quarantine_check'] = 'integrity' /
'acoustid' / 'bit_depth'. Skips ONLY the named check — other quality
gates stay live. No blanket bypass-all flag.

Sidecar expansion: move_to_quarantine now persists the full
json-serializable context via serialize_quarantine_context (drops
non-JSON-safe values, walks nested dicts/lists/sets, str-coerces
unknown objects) plus the trigger name. Existing thin sidecars are
detected and routed to Recover instead of Approve.

Pure helpers in core/imports/quarantine.py: list_quarantine_entries
/ delete_quarantine_entry / approve_quarantine_entry /
recover_to_staging / serialize_quarantine_context. 27 tests pin
every shape: orphan files / orphan sidecars / corrupt sidecars /
collision-safe filename restoration / full-context vs thin-sidecar
dispatch / json round-trip safety.

Four new endpoints in web_server.py — thin glue around the helpers:
GET /api/quarantine/list, DELETE /api/quarantine/<id>,
POST /api/quarantine/<id>/approve, POST /api/quarantine/<id>/recover.

Download modal status differentiates "🛡️ Quarantined" from
" Failed" so recoverable files are visible at a glance — checked
against the error_message text, no schema change needed.

Pipeline changes are three minimal per-check conditionals at the
existing quarantine sites in core/imports/pipeline.py. Each
move_to_quarantine call now passes its trigger name so the sidecar
records which check fired.

177bd85355 Configurable duration tolerance for downloaded-file integrity check
Previously hardcoded at 3s (5s for tracks >10min) — files drifting
past that got quarantined with no user override. Live recordings,
alternate masterings, and some legitimate uploads routinely drift
further.

New setting `post_processing.duration_tolerance_seconds`. Default 0
means "use auto-scaled defaults" (unchanged behavior for users who
don't touch it). Positive value overrides the per-track defaults.
Capped at 60s — past that the check is effectively off.

Logic lifted to pure helper `resolve_duration_tolerance` in
file_integrity.py. Coerces every plausible input (None / empty /
zero / negative / unparseable / above-cap / numeric string / float)
to either a float override or None for auto. 12 tests pin every
shape.

Wired into `core/imports/pipeline.py` at the integrity-check call
site — runs for ALL matched downloads (Soulseek / Tidal / Qobuz /
HiFi / YouTube / Deezer-direct) since they all share that pipeline.

0769fcd5cc Fix Soulseek downloads losing collab artist tags
Soulseek matched-download contexts populate `original_search_result`
with `artist` (singular string) and no `artists` list — the full
multi-artist array lives on `track_info` (the matched Spotify track
object). `extract_source_metadata` only read `original_search.artists`,
so the Soulseek path always fell through to the single-artist branch
and TPE1 ended up with the primary artist only. Deezer-direct
downloads were unaffected because their context populates
`original_search.artists` as a proper list.

Lifted artist resolution into a pure helper
`core/metadata/artist_resolution.py:resolve_track_artists` that walks
`original_search.artists` → `track_info.artists` → `artist_dict.name`
fallback chain. Normalizes mixed list-item shapes (Spotify-style
dicts, bare strings, anything else stringified) and drops empty
entries.

13 new tests pin the resolution order, fallback chain, mixed-shape
normalization, whitespace stripping, and empty/none handling. The
existing `_artists_list` no-fall-through test in
`test_multi_artist_tag_settings.py` was updated to reflect the new
contract (always populated; multi-value write still gated on
`len > 1`) plus a new regression test for the Soulseek shape.

Composes with the existing Deezer per-track upgrade (still fires when
single-artist + track_id available) and feat_in_title /
artist_separator settings (still drive the joined ARTIST string
downstream).

8a11a660af Extract manual import route handlers
Move the remaining manual import endpoint logic out of web_server.py and into core.imports.routes behind ImportRouteRuntime. The Flask endpoints now stay as thin compatibility wrappers for album/track search, album match/process, single-file import processing, and batched singles processing.

Keep legacy test patch points intact by re-exporting build_album_import_match_payload from web_server and routing singles_process through an injected process_single_import_file callable. This preserves existing route-level monkeypatch behavior while keeping the extracted helper testable.

Add focused helper coverage for Hydrabase enqueueing, search limit clamping, album match payload forwarding, album import side effects, single-file worker outcomes, malformed manual matches, and singles aggregation/injected-worker behavior.

89246a7304 Write artist.jpg to artist folder so Navidrome shows real photos
Closes #572 (rhwc).

Navidrome has no API for setting an artist image — it reads
`artist.jpg` (or `folder.jpg`) from the artist folder during
library scans. SoulSync's `update_artist_poster` for Navidrome
was a no-op, so users only ever saw album-art-derived thumbnails
as the artist photo.

- new "Write Artist Image" button on artist detail page
- POST /api/artist/<id>/write-image-to-disk derives the artist
  folder from any track's resolved file_path (reuses
  _resolve_library_file_path so docker mount translation +
  library.music_paths probes from #558 apply), fetches the photo
  from the configured metadata source priority chain, downloads
  with content-type validation, writes atomically via
  `<filename>.tmp + os.replace`
- when active server is Navidrome, triggers a library scan
  immediately so the file is picked up
- respects existing artist.jpg (frontend prompts before
  overwriting) so user-supplied photos aren't clobbered
- works for plex / jellyfin too as a fallback layer — both
  servers also read artist.jpg from disk

26 tests pin the pure helpers in core/library/artist_image.py:
folder derivation (trailing sep / empty / non-string), URL
picking (missing attr / whitespace / non-string), download
(non-image content-type / 404 / timeout / empty body), atomic
write (replace / temp-cleanup-on-failure / overwrite guard /

- post-processing step infers observable changes from source-vs-
  final state (format conversion, file rename via tag template,

56ae10693b Album Completeness: surface diagnostic when resolver can't find album folder
GitHub issue #558: clicking Auto-Fill / Fix Selected on the Album
Completeness findings page returned a flat "Could not determine album
folder from existing tracks" error with no diagnostic. Reporter is on
Navidrome on Docker — the path resolver in
`core/library/path_resolver.py` couldn't find any of the album's tracks
on disk because Navidrome's Subsonic API doesn't expose filesystem
library paths the way Plex's API does (probed in #476). Default
settings → `library.music_paths` empty → no base directories to probe →
silent None. User had no signal about what to configure.

Not a regression of #476 — that fix targeted Plex auto-discovery and
worked correctly for it. Navidrome was never covered because the
protocol gives the resolver nothing to probe.

Fix scoped to the diagnostic surface, not auto-magic discovery:

- Added `resolve_library_file_path_with_diagnostic` returning
  `(resolved, ResolveAttempt)`. ResolveAttempt records what the resolver
  tried — `raw_path_existed`, `base_dirs_tried`, `had_config_manager`,
  `had_plex_client`. Pure data, no rendering opinions.
- Legacy `resolve_library_file_path` becomes a thin wrapper that
  drops the attempt; every existing call site is unchanged.
- `RepairWorker._fix_incomplete_album` now uses the diagnostic helper
  and renders a multi-part error via `_build_unresolvable_album_folder_error`:
  names the active media server, shows one sample DB-recorded path,
  lists every base directory the resolver actually probed, and points
  the user at Settings → Library → Music Paths as the actionable fix.
- Distinguishes empty-base-dirs vs tried-and-failed cases so the user
  knows whether to add a mount or fix the existing one.
- No auto-probing of common Docker conventions (`/music`, `/media`, etc).
  Speculative — could resolve to wrong dirs on the suffix-walk if a
  conventional path happens to contain a partial collision. User stays
  in control.

12 new tests:
- 7 in `tests/library/test_path_resolver.py`: tuple-shape contract,
  raw-path-existed short-circuit, base-dirs listed even on walk
  failure, had-flags reflect caller inputs, no-base-dirs returns
  None with empty attempt, legacy `resolve_library_file_path`
  delegates correctly across happy / suffix-walk / failure paths.
- 8 in `tests/test_repair_worker_unresolvable_folder_error.py`:
  active server name in error, sample DB path verbatim, base dirs
  listed, empty-base-dirs phrased differently, Settings hint always
  present, defensive against None attempt / missing sample / missing
  config_manager.

698ecc99f0 Import history: Clear History button now sweeps stuck 'processing' rows
Reported: Clear History button on the Import page left zombie rows
behind. Every survivor showed "⧗ Processing" status from 2-9 days ago.

Trace: `_record_in_progress` inserts a `status='processing'` row up-front
so the UI can render the in-flight import while it runs; `_finalize_result`
updates it to `completed`/`failed` when the import finishes. When the
worker is killed mid-import (server restart, crash), the row never gets
finalized — stays at `processing` forever. The clear-history endpoint's
SQL `DELETE ... WHERE status IN (...)` listed every terminal status but
omitted `processing`, so zombies survived every click.

Fix: add `processing` to the delete list, but guard against nuking
genuinely-live imports by intersecting against the worker's
`_snapshot_active()` map — any folder hash currently registered in
`_active_imports` is excluded from the delete via an `AND folder_hash
NOT IN (...)` clause. `pending_review` deliberately left out so user
still has to approve/reject those explicitly.

One endpoint touched (`/api/auto-import/clear-completed` in
web_server.py). No worker changes — guard reuses the existing
`_snapshot_active()` method that the UI poller already calls.

5 new tests in `tests/imports/test_auto_import_clear_completed_endpoint.py`:
- Zombie `processing` rows swept, live `processing` row preserved

3af2d34cee Auto-import: fall through to other metadata sources when primary returns no match
Discord report: 16 Bandcamp indie albums sat in staging because
auto-import couldn't identify them, but the manual search bar at the
bottom of the Import Music tab found the same albums fine. Trace:
`_search_metadata_source` only queried `get_primary_source()` — single
source, no fallback. Meanwhile `search_import_albums` (manual search bar)
already iterated `get_source_priority(get_primary_source())` and broke
on the first source with results. Asymmetric behavior, same album: manual
worked, auto-import didn't.

Fix: lift `_search_metadata_source` to use the same source-chain pattern.
Try primary first; if it returns nothing OR scores below the 0.4
threshold, fall through to the next source in priority order. First
source producing a strong-enough match wins. Result dict carries the
`source` that actually matched (not the primary name) so downstream
`_match_tracks` calls the right client. Defensive per-source try/except
so a rate-limited or auth-failed source doesn't abort the chain.
Unconfigured sources (client=None) silently skipped.

Cin-shape lift: scoring math extracted to pure `_score_album_search_result`
helper so the weight tweaks (album 50% / artist 20% / track-count 30%)
are pinned at the function boundary, independent of the orchestrator
(per-source iteration, exception containment, threshold check). Weight
constants exposed at module level (`_ALBUM_NAME_WEIGHT`,
`_ARTIST_NAME_WEIGHT`, `_TRACK_COUNT_WEIGHT`) — greppable, bumpable in
one place. Pre-extraction these were magic numbers inline.

27 new tests:
- 9 integration tests in `test_auto_import_multi_source_fallback.py`:
  primary-success path unchanged (no fallback fires, only primary client
  called), primary-empty falls through, primary-weak-score falls through,
  first fallback success stops the chain (no wasted API calls on
  remaining sources), all-sources-fail returns None, per-source
  exception contained, unconfigured-source skipped, result `source`
  field reflects winning source, `identification_confidence` from
  winning source.
- 18 helper tests in `test_album_search_scoring.py`: weights sum to
  1.0, album weight dominant (invariant pin), perfect-match returns 1.0,
  per-component contribution (album / artist / track-count), Bandcamp
  vs streaming track-count mismatch (7-files vs 4-tracks case still
  scores ~0.87 above threshold), zero-track-count and zero-file
  guards, huge-mismatch non-negative guard, list-of-strings artist
  shape, missing `.name` / `.artists` / `None` total_tracks edge cases.

Backwards compatible: single-source users see no change — chain just
has one entry. Existing test `test_search_metadata_source_extracts_artist_id_from_dict_artist`
needed one extra patch line for `get_source_priority`.

d5de724f9b Multi-artist Deezer upgrade + double-append guard hardening
Two follow-ups to the multi-artist tag settings PR:

1. Deezer contributors upgrade — closes the "known limitation"
   flagged in the prior commit. Deezer's `/search` endpoint only
   returns the primary artist for each track; the full contributors
   array (feat., remix collaborators, producers credited as artists)
   lives on `/track/<id>` and gets parsed by `_build_enhanced_track`.
   Without the upgrade Deezer-sourced tracks never got multi-artist
   tags even with the right settings on.

   Fix in `core/metadata/source.py`: when source==deezer AND the
   search response had a single artist AND a track_id is available,
   fetch full track details via `get_deezer_client().get_track_details`
   and replace `all_artists` with the upgraded list.

   - One extra API call per affected Deezer track
   - Skipped when search already returned multiple (no-op fast path)
   - Skipped for non-Deezer sources (Spotify/Tidal/iTunes search
     responses already include all artists)
   - Skipped when no track_id is available
   - Defensive try/except: on /track/<id> failure (network error,
     deezer client unavailable), fall through to the search-result
     list — never lose the data we already had

2. Double-append guard hardened with a word-boundary regex.
   Prior commit checked for `"feat." not in title.lower() and "(ft."
   not in title.lower()` — too narrow. Source platforms produce
   wildly different feat-marker conventions: "(feat. X)", "(Feat X)",
   "(FEAT X)", "(Featuring X)", "[feat. X]", "ft. X" (no parens),
   "FT. X", etc. Any of these as the SOURCE title would cause a
   double-append: `"Track (Feat X) (feat. Y)"`.

   Replaced with `re.search(r'\b(?:feat|feat\.|featuring|ft|ft\.)\b',
   title, IGNORECASE)`. Word-boundary regex catches every common
   variant. Substring matches like "Aftermath" containing `ft`
   correctly fall through to the append path (pinned by a regression
   test).

16 new tests (29 total in the file):
- 9 parametrized variants of the double-append guard
- 1 substring guard ("Aftermath")
- 6 Deezer upgrade scenarios (fires when expected, doesn't fire
  for non-Deezer / multi-artist search / no track_id, defensive
  fall-through on failure, no false-positive when /track/<id>
  confirms single artist)

c11a5b7eab Multi-artist tag settings: implement artist_separator + feat_in_title + populate _artists_list
Three settings on Settings → Metadata → Tags were partially or
completely unimplemented. Reporter (Netti93) traced each one.

(1) `write_multi_artist` only "worked" because of a never-populated
    `_artists_list` field. `core/metadata/source.py` built
    `metadata["artist"]` as a hardcoded ", "-joined string but never
    assigned `metadata["_artists_list"]`. `core/metadata/enrichment.py`
    line 107 reads that field and gates the multi-value tag write
    on `len(_artists_list) > 1` — always saw an empty list, silently
    no-op'd the write.

(2) `artist_separator` (default ", ") was referenced in the UI +
    settings.js save path but ZERO Python code read the value. Every
    multi-artist track ended up with hardcoded ", " regardless of
    what the user picked.

(3) `feat_in_title` (when true: pull featured artists into the title
    as " (feat. X, Y)" and leave only primary in the ARTIST tag —
    Picard convention) had no implementation at all.

Fix in source.py:

* Populate `_artists_list` from the search response's artists array
* Read `feat_in_title` and `artist_separator` configs
* When `feat_in_title=True` and >1 artist: ARTIST = primary only,
  append "(feat. X, Y)" to title with double-append guard
* Else: ARTIST = artists joined with `artist_separator`
* Single-artist case unaffected by either setting

Double-append guard uses a word-boundary regex catching all common
"feat" variants source platforms produce — `feat`, `feat.`,
`featuring`, `ft`, `ft.` — case-insensitive. Substring matches
(e.g. "Aftermath" containing "ft") correctly fall through to the
append path.

Fix in enrichment.py ID3 branch:

* TPE1 stays as the display string (with separator or primary-only
  per the user's settings)
* Multi-value list goes to a separate `TXXX:Artists` frame (Picard
  convention) when `write_multi_artist` is on
* Pre-fix the ID3 path wrote TPE1 twice — single-string then list
  — and the second `add` overwrote the first, clobbering both the
  configured separator AND the feat_in_title semantics. Vorbis path
  was already correct (separate "artist" + "artists" keys).

Known limitation (flagged in WHATS_NEW): Deezer's `/search` endpoint
only returns the primary artist. The full contributors array lives
on `/track/<id>`. Enrichment uses search-result data so Deezer-
sourced tracks may still get only the primary artist until a follow-
up commit wires the per-track contributors fetch into the enrichment
flow. Spotify, Tidal, and iTunes search responses include all
artists so they work now.

23 new tests in `tests/metadata/test_multi_artist_tag_settings.py`:

* `_artists_list` populated for multi/single/no-artist cases
* `artist_separator` drives ARTIST string (default ", " + custom
  ";" + custom "; " + " & ")
* Single-artist case unaffected by either setting
* `feat_in_title=True` pulls featured to title, leaves primary in
  ARTIST
* `feat_in_title` no-op for single artist
* Double-append guard recognizes 9 source-title variants ("(feat.
  X)", "(Feat. X)", "(FEAT X)", "(feat X)", "(Featuring X)",
  "[feat. X]", "ft. X", "(ft X)", "FT. X")
* Substring guard test pins "Aftermath" doesn't false-positive
* Combined-settings precedence: feat_in_title wins ARTIST string
  but `_artists_list` carries everyone for multi-value tag

fc573a5f19 AudioDB worker: stop infinite loop on direct-ID lookup failure (#553)
Track enrichment was stuck in a constant retry loop. Logs showed
nothing but `Read timed out. (read timeout=10)` from
`lookup_track_by_id` repeating against the same track ID. AudioDB
itself was being hammered nonstop with no progress.

Cause: when an entity already has `audiodb_id` populated (from a
manual match or earlier scan) but `audiodb_match_status` is still
NULL — an inconsistent state some import paths can leave behind —
the worker tries a direct ID lookup. If that lookup fails (returns
None on timeout, which AudioDB's `track.php` endpoint hits
frequently because it's slow), the prior code logged "preserving
manual match" and returned WITHOUT marking status. Row stayed NULL
→ queue's NULL-status filter picked it up next tick → tried direct
lookup → timed out → returned → infinite loop.

The "preserve manual match" intent was correct: don't fall through
to the name-search path because that could overwrite a manually-set
`audiodb_id` with a wrong guess. Bug was the missing `_mark_status`
call before the early return.

Fix:

* `_process_item` direct-lookup-failure branch now calls
  `_mark_status(item_type, item_id, 'error')` before returning. The
  existing `audiodb_id` is preserved (column not touched). Queue's
  NULL-status filter no longer re-picks the row.

* `_get_next_item` retry-cutoff queue priorities (4/5/6) extended
  from `audiodb_match_status = 'not_found'` to
  `audiodb_match_status IN ('not_found', 'error')`. Same `retry_days`
  window. Transient AudioDB outages still recover automatically;
  permanently-broken IDs eventually get re-attempted once a month
  rather than staying errored forever.

5 new tests in `tests/test_audiodb_worker_stuck_track.py` use a real
SQLite DB (not mocks) so the SQL queries are actually exercised:

  - lookup-returns-None marks status='error' (no infinite loop)
  - lookup-raises-exception marks status='error' (defensive)
  - lookup-success preserves the existing match-success path
  - error-status row past retry-cutoff gets picked up again
  - error-status row within cutoff stays skipped (loop prevention
    works)

Only triggers for entities in the inconsistent `audiodb_id` set +
`match_status` NULL state. Happy path and already-matched /
already-not-found rows unchanged. Full pytest 2698 passed.

Closes #553.

4fb9f38798 Your Albums: selectable wishlist modal + Tidal album resolution
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)

7a23d60f28 AcoustID scanner: file-tag fallback for legacy compilation tracks
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.

f4c433c151 Tidal: rewire favorite albums + artists to V2 user-collection endpoints
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.

6fe85f2f37 Server playlist sync: append mode (preserve user-added tracks)
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).

WHATS_NEW entry under new '2.6.0' block (hidden by
`_getLatestWhatsNewVersion` until next release bump).

f28f9808db Tidal: surface Favorite Tracks as virtual playlist (issue #502)
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.

b5b6673216 Reorganize: hint at Unknown Artist Fixer for placeholder-metadata rows
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.

d944a166f8 Reorganize: move orphan-format siblings alongside the canonical
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.

812db1fbbf AcoustID scanner: prefer track_artist for compilation albums
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)

df304eb016 AcoustID scanner: handle multi-value artist credits
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)

- `TestSplitArtistCredit` — parametrised across 12 credit-string
  formats (comma, ampersand, semicolon, slash, plus, feat./ft./

  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

  threshold still respected

`tests/test_acoustid_scanner.py` (+3):

8a4c0dc92a Deezer cover-art download: fallback to original URL on CDN refusal
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)

80cf16339c Deezer cover art: upgrade CDN URL to 1900×1900 (was embedding 1000×1000)
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

- 560/560 metadata + imports tests pass (no regression)

bc34d39ce9 Tighten alias-lookup trust + add ambiguity gate + diagnostic log
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).

# Tests added (5)

- `test_moderate_confidence_match_now_skipped_strict_threshold`
- `test_ambiguous_results_skipped`

  emits INFO log
- `test_no_log_when_direct_match_succeeds` — happy path quiet
- `test_no_log_when_alias_doesnt_help` — failed path also quiet

# 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 —

  threshold easily

11397307b2 Alias resolution polish: lazy-fire on direct-match failure + worker backfill
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.
- `TestAliasProviderCallable` (3): iterable passed directly,

  direct sim.

7066233c37 Wire alias-aware artist match into AcoustID verifier — fixes #442
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
  falls back, aliases don't mask genuine mismatches

- Performance: alias lookup fires ONCE per verification regardless
  of recording count

15244f24cf Live MB lookup for un-enriched artists with cache
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)
- Ruff clean

48d848bb74 MB worker populates artists.aliases on enrichment
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

235ada7e0f Add pure artist-name comparison helper with alias awareness
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.

c02d51d60d Plex: trigger_library_scan + is_library_scanning use auto-detected section — fixes #535
# 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

- 13 new tests pass
- 84/84 media_server tests pass (no regression in the existing
  Plex / Jellyfin / Navidrome suite)
- 2458 full suite passes (+13 from baseline)
- Ruff clean
