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.
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.
`core/streaming/prepare.py:94-97` creates /app/Stream lazily via
`os.makedirs(stream_folder, exist_ok=True)` on first playback. Under
standard Docker this works because the container's `root` writes /app
without restriction. Under rootless Docker / Podman the in-container
soulsync UID maps to a host UID that can't write to /app, so the
mkdir silently fails and the streaming "Play" flow errors out with
no obvious user-facing cause.
Same root cause + same fix shape as the May 2026 /app/Staging restart-
loop fix — pre-bake the directory at image build time (when the layer
is owned by root), and thread it through every entrypoint.sh spot that
touches the canonical app-dir list.
Not added to VOLUME — /app/Stream is a transient single-file cache
(cleared on every new playback), no persistence value.
Touched lines:
- Dockerfile: mkdir + chown line that pre-bakes runtime dirs.
- entrypoint.sh: the recursive chown gated on UID change, the always-runs
mkdir + chown, and the writability audit loop.
No code change. Streaming tests pass unchanged (they use tmp_path, not
/app/Stream).
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.
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.

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.
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.
t2tunes uses HTTP 400 for transient Amazon-side failures instead of 5xx.
The first API call in a fresh session hit this every time, so album and
artist searches always failed while the track search (called 0.5 s later)
got through.
- _get_json: retry up to 3 times (1 s, 2 s backoff) on t2tunes-specific
400 "Failed to search" responses
- All search_raw calls switched from types="track,album" to types="track"
— t2tunes album-type queries are currently broken server-side; albums
and artists are now derived from track result metadata instead
- search_albums: drop is_album filter, extract album fields from track hits
- get_album_tracks: fall back to stream index (1-based) when t2tunes tags
omit trackNumber, preventing every track landing as track 01
If history.back() navigated away from artist-detail entirely (e.g. to
library), _artistDetailGoingBack stayed true. The next forward artist
navigation would then pop the label stack instead of pushing, causing
the back-button label to show plain Back instead of the correct page.
Guard the pop with currentPage === artist-detail; clear the flag
unconditionally in the else branch.
PR #644 removed the back-button label logic as collateral when removing
the full originStack. The label is independent of the stack — restore it
without restoring the old click-handler navigation (browser history handles
that now).
- _artistDetailLabelStack: module-level stack of {type:'page',pageId} or
{type:'artist',name} entries, pushed on forward navigation, popped on back
- _artistDetailGoingBack flag: set by the back button click handler so
navigateToArtistDetail knows to pop instead of push when called by the
React route on browser-history navigation
- Backfill currentArtistName from the API response so URL-driven entries
(which pass '' for name) have real names on state before the next similar-
artist navigation pushes them onto the stack
- No-history fallback navigates to the recorded origin page
URL-driven routing (PR #644) no longer passes the display name as a query
param to the artist-detail endpoint. The source-only detail builder fell back
to artist_id when artist_name was empty, surfacing the raw MBID as the page
title for MusicBrainz artists.
Two fixes in build_source_only_artist_detail:
- Drop the artist_id fallback in resolved_name so an MBID can never become
the display name
- Add a musicbrainz elif branch (matching the Spotify/Deezer/iTunes pattern)
that calls MusicBrainzSearchClient.get_artist() to resolve the real name
and genres from the MBID when no name is provided
- avoid calling buildArtistDetailPath when a similar artist has no usable id
- render a disabled bubble instead so empty MusicBrainz IDs do not crash the panel
- no need for a separate effect since we can use the existing one
- no need to cancel the similar artists query upon entering, since the
unregister callback already does it
- replace click-driven artist-detail hops with semantic links
- keep SPA transitions via shell bridge interception for /artist-detail/:source/:id
- drop legacy page helper wrappers and dead bridge plumbing
- expose a shell-bridge cancel primitive for similar-artists loading
- stop stale similar-artists streams from the artist-detail route lifecycle
- keep the legacy loader abort-only and make abort logs page-agnostic
- update bridge and route tests for the new cleanup path
- add a canonical TanStack route for artist-detail and keep the legacy page as the renderer target
- expose page-level artist-detail navigation on the shell bridge for legacy callers
- remove artist-detail-specific routing, origin stack, and back-label logic from the shared shell helpers
- add canonical /artist-detail/:source/:id TanStack route
- hand the legacy page off through the shell bridge
- remove artist-detail branching from generic shell helpers
Include cover-art-archive in the get_release call so _render_release_as_album
can check whether the representative release actually has front art before
building the URL. Prefer release-scope when confirmed present; fall back to
release-group scope otherwise. Prevents storing a release-group URL that CAA
reports as having no art.
- watchlist_scanner: fall back to album.image_url when album object has no
images list (affects MusicBrainz CAA URLs, iTunes, Deezer — all use
image_url on the Album dataclass, not the Spotify-style images array)
- Pulse Downloads nav icon while active downloads are in progress, same
pattern as watchlist scan animation
Add MusicBrainz watchlist artist ID storage, badges, linked-provider editing, and per-artist preferred source support.
Backfill watchlist MusicBrainz matches from already-enriched library artists so existing MusicBrainz worker matches appear in watchlist cards and settings.
Extend bulk watchlist add, liked artist matching, artist map source picking, and service status labels to recognize MusicBrainz, with regression tests for watchlist ID persistence and backfill.
Register MusicBrainz as a first-class metadata source alongside Deezer, iTunes, Spotify, Discogs, and Hydrabase. Expose the shared client through metadata services, add the settings option, and expand the MusicBrainz search adapter with source-compatible artist, album, track, and detail methods.
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.
Manual matches can be created from sync history as mirrored while wishlist and download flows later see the same track as wishlist or a provider source. 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.
Add coverage for mirrored-source matches being honored by wishlist cleanup and download batches, including the internal wishlist force-download path.
Ensure the Amazon enrichment worker verifies its required columns before querying pending work or progress, preventing upgraded installs from spamming no-such-column errors when amazon_match_status is missing.
Add regression coverage for legacy databases without Amazon enrichment columns.
Use the first available album, EP, or single artwork when an artist portrait is missing or fails to load, keeping artist detail pages visually populated across library and source-only artists.
Refresh the PR description for the artist detail deep-link branch.
Preserve source metadata for seasonal and cached discover album modals so artist links use real provider IDs instead of falling back to library/name routes.
Treat source-only artist detail discographies as clickable missing releases and skip library-only ownership/enhancement checks.
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
