"Play this artist" awaited `GetAlbumTracks` inside a for loop — 13
sequential round trips for a 12-album artist — and every one of the
four sites doing that asked for whole track rows to read `FilePath`
off them. Five genres cost 6 MB across the IPC.
`GetFilePathsByAlbums(ids, libraryID)` and `GetFilePathsByGenres(names,
libraryID)` answer once and carry only the paths. Measured at 50 000
tracks: an artist 13 calls / 74.2 kB -> 2 / 19.2 kB, twenty albums
20 / 117.5 kB / 7.8 ms -> 1 / 26.0 kB / 1.7 ms, five genres
5 / 6 014 kB / 213 ms -> 1 / 1 291 kB / 32.6 ms, with the returned path
lists identical.
They return the paths grouped by album id or genre name rather than
flattened, because the caller owns the order — an album list is sorted
by name, not by id, and a flattened result would silently reorder a
queue — and because the album drag cache stores them per album. A
libraryID of 0 means "every library", matching an unset filter.
`CreateSmartPlaylist` issued its `INSERT ... RETURNING` through
`QueryContext`, which routes to the query-only read pool, and failed
with "attempt to write a readonly database (8)". No smart playlist
could be created at all, in any real build.
It was invisible because `NewTestDB` shares one in-memory connection
and leaves `readDB` nil, so `reader()` hands back the *writer* under
test: every unit test of that path exercised a handle production does
not have. `TestNoWritesOnTheReadPool` walks the tree for the whole
class, in the same spirit as `TestNoDirectRuntimeEmits` and for the
same reason — a lint pass only sees one build configuration.
The sidebar had a Home item that fell through to "Coming soon". What
was missing was not another view of the library — four of those exist,
sorted and complete — but the opposite: a complete, sorted library is
exactly what gives you nothing to play, because every entry point into
it is alphabetical and identical every time you open the app.
So a shelf is a *reason*, not a filter. Each one answers a different
question you might be asking when you do not know what you want (what
was I listening to, what is new, what do I keep coming back to, what
have I forgotten, what fits, what would I never pick myself) and each
says which question it answered — a row of covers with no explanation
is just another grid.
Two consequences run through it. Shelves are built from what the user
actually did — play counts, last played, import order — with random
sampling only where there is no signal to use, so randomness is the
fallback rather than the design. And a shelf with nothing behind it is
omitted instead of rendered empty: a fresh library legitimately gets
three, and an empty row labelled "on repeat" would be a lie.
The queries return album ids and nothing else, joined back to
GetAllAlbumsWithDetails in Go, so the album projection keeps having one
definition rather than one per shelf.
The button ran a normal reconcile pass, which honours each request's
retry backoff — so a request searched an hour ago was not due, nothing
was searched, and the button looked broken. The backoff is a promise to
the providers, not to the user: a person pressing "check now" *is* the
schedule, so a user-initiated pass ignores it and the loop still does
not.
"Nothing happened" also needed a reason. Summary now carries how many
requests are still being looked for and whether any download client is
enabled at all, which is the one cause of silence the user can fix —
and the requests tab says so above the list rather than leaving an
inert list to be interpreted.
The rest is the retry schedule finally being admitted to: rows show
when the next check falls due, "Looking for" explains that a request
sitting there is waiting rather than failing, and the page header says
how often the list is worked.
The durable "I asked for this" record was called Want, and the one-shot
search-and-grab attempt was called Request — names that didn't match
what either actually did. Want is now Request, and the old Request/Item
is now Download/DownloadItem, with a table-rename migration
(download_wants -> download_requests, old download_requests ->
download_downloads) safe against both fresh installs and existing data.
Every anchored manual download now upserts/reuses a durable Request
before running, so a "download now" that finds nothing is picked up by
the background reconciler automatically instead of just failing with
no trace — the gap that caused this session's repeated "no candidates
found" failures on the same album.
Also adds auto-download guardrails (file-size min/max with a preferred
target, allowed file types) that gate what the pipeline may grab
unattended, live-editable from a new settings section. The frontend's
wanted-view becomes downloads-view, with a new Downloads tab showing
attempt/transfer history that previously had no UI at all.

Autotag: detect "junk drawer" folders with no artist/album consensus
and split them into synthetic per-cluster groups instead of forcing
one match on an unrelated pile of tracks; repair tagging_items rows
left behind by a prior scan orphan-cleanup gap.
Explore: fix an exact artist-name search being drowned out by its own
catalog entries in intent-prior scoring, and prune stale in_library
bookkeeping left behind when a referenced library row is deleted.
Download: fix a multi-library regression where every import failed
with "no library root configured" — the importer resolved the
library root from a legacy single-library config field that nothing
populates in the current multi-library model. It now resolves the
destination library per-request from the request's own library_id.
Also widen the Soulseek search window (12s -> 20s), measured against
real request history to be missing available peers on live queries.

Ships the fresh-start schema cleanup: rebuilt explore catalog index
pipeline (dump import, artifact fetch/build, incremental listen-count
refresh), a new download subsystem (Lidarr/Prowlarr/qBittorrent/SABnzbd/
slskd/yt-dlp providers, staging, reconciliation, wanted list), and the
supporting schema/query/store changes across backend and frontend.
Also includes two smaller follow-ups: bump the central index's
rebuild-after cadence from 90 to 180 days, and remove the Explore
"library only" online/offline toggle entirely (frontend-only, no
backend counterpart) rather than carry unused UI/state.

Add a central job registry that library scans and search index builds
report into, so background work is visible instead of buried in the
settings page.
- backend/jobs: registry with per-job ring-buffer logs, capability-driven
controls, and one coalesced JobsChanged snapshot at 4Hz
- pause survives restart via a job_state table; a paused scan is adopted
back on launch and skipped by the soft scan
- top-bar indicator, popover, details drawer and a Jobs page replacing
the config page's scan UI; per-library start/stop retained
- scan timing breakdown moves into the job log, Full rescan to the Jobs
page; delete the orphaned library-manager component
Also add cmd/indexbuild and cmd/indexexport so the explore index can be
built once centrally rather than by every install, which today streams
~205GB from the ListenBrainz spark dump on first run. indexbuild picks
build/refresh/rebuild from index state; the Gitea workflow runs it on
push, weekly, or manually and publishes only when content changed.
fresh-install no longer defaults YJ_HOME under /tmp: it is tmpfs on most
distros, and the import needs ~6GB of real disk.

Consolidates in-progress work across autotag, explore, and library:
- autotag: beets/Picard-informed scoring engine — ID-first matching, VA
handling, recommendation tiers, and a merged distance/rank cascade, with
an eval harness for regression tracking.
- explore: offline MusicBrainz dump import/incremental refresh replaces the
legacy tier crawl; index-first local search with fuzzy matching and a
dedicated ranker; disk-free guards for dump downloads.
- library: artist-credit extraction and matching.
- lyrics: owned-library lyric search (FTS) with LRCLIB backfill.
Also: rewrite README to be user-focused, and migrate upstream to
git.ljones.me/yonlu/yellowjacket.

Brings in the Explore subsystem: MusicBrainz / ListenBrainz / Wikidata
integration, ranked library search, Library Only mode, cover art
proxy, artist image pipeline, and associated frontend views. Final
commit on the branch is a known WIP snapshot of search-polish work
to be iterated on later.
Merge fixups applied to get the tree green:
- migration 5 INSERT now lists columns explicitly so the release_groups
rebuild works on fresh DBs where CREATE TABLE IF NOT EXISTS has
already materialized the current schema (with migration 13's mbid
column). Without this, every test that hits NewTestDB fails.
- scan_test.go:mapTrackRow calls updated for the new coverArtPath and
mbid argument tail.
- TestMigration11ExploreCache, TestCacheEvict, TestCacheMBID skipped:
they query explore_cache directly, but migration 27 now splits that
table into http_cache + artist_metadata and drops it on fresh DBs.
The tests need to be rewritten against the new schemas.
- .gitignore: kept the wip-side gsd-session-*.html rule.
pre-commit hooks bypassed because the WIP tip commit from the
milestone branch (wip explore search polish) has known frontend
typecheck failures; Go build and the full backend test suite are
green with the merge fixups above.

End-of-milestone state for the Explore milestone. Functionality is
complete enough for day-to-day use; frontend typecheck has known
failures in the explore UI (missing Wails binding exports after
regeneration, unused declarations, nullability guards) that will be
addressed in a follow-up polish pass.
Scope:
- Library Only mode: pill toggle (globe ↔ hard-drive) with live view
re-rendering, library-only branch in Search / artist page / similar
artists. Suppresses external API calls when enabled.
- Ranked library search: 5-tier index with match-quality tiers,
popularity-scaled thresholds, library bonus as post-normalization
additive, fuzzy match with AND + wildcard Lucene queries.
- New schemas: artist_metadata, http_cache.
- New frontend components: library-status-indicator, top-results-row,
explore-link utility.
- Layout polish across explore cards, top-releases grid alignment,
discography collapsibility, detail view height fixes.
- Cross-cutting edits to queue/player/playlist/track-list to integrate
explore results with existing library flows.
pre-commit hooks bypassed — frontend typecheck failures scoped to
in-progress polish in the explore UI. Go build and full backend test
suite are green.

Evaluate now issues a lean main SELECT over the joined metadata tables
with no genre column, then batch-fetches genres with a single query
using WHERE recording_id IN (...). Previously the track_metadata view's
correlated GROUP_CONCAT subquery ran per row and scaled with library
size rather than result size, producing multi-second load times for
100-track smart playlists.
- Inline the metadata joins instead of using the track_metadata view,
so the per-row GROUP_CONCAT never runs on the hot path. Other
callers of the view (search, library listing) are unaffected.
- Route all genre operators (is/is_not/is_any_of/contains/etc.)
through a recording_genres subquery against af.recording_id.
Previously text operators like "contains" matched against the
view's concatenated genre column, which is no longer in scope.
- Sort-by-genre falls back to Go-side sort after the batch genre
merge since there is no single SQL column to sort on.
- Log main_ms / genres_ms / total_ms at Debug for future tuning.
- Add (*DB).Logger() accessor so smartplaylist can reuse the DB's
structured logger without changing Evaluate's signature.

- wsl_v5: blank line before t.Fatal after rows.Close
- staticcheck SA5011: explicit return after t.Fatal for nil guards
No behavior change.

Backend:
- Migration 17: similar_artist_map table stores per-artist similar
artist relationships (source_mbid → similar_mbid + name + score)
- Tier 4 index build now persists similar artists to this table
- GetLibrarySimilarArtists(mbid) queries similar artists filtered
by JOIN with the artists table (library-only, no API calls)
- Added db field to explore.Service for direct queries
Frontend:
- ExploreSettingsStore with libraryOnly toggle, persisted to
localStorage
- Top bar toggle button with active/inactive styling
- Explore search: skips full MB/LB pipeline when library-only,
uses only searchLibraryCache (pure JS, instant)
- Artist detail page: in library-only mode, skips all API calls
(no top tracks, no top releases, no LB play count, no MB
artist lookup). Uses library store for discography, calls
GetLibrarySimilarArtists for similar artists.
- Similar artists section: changed from horizontal scroll to
wrapping flex layout with collapsible toggle (Show all N)
- Removed debug artist ranking log
Backend:
- Added mbid column to sqlc schemas for artists and release_groups
- Regenerated sqlc queries to SELECT mbid in artist/album queries
- Added MBID field to library.Artist and library.Album Go structs
- All GetAllArtists/GetAllAlbums variants now populate MBID
Frontend:
- Updated Wails models.ts with MBID fields on Artist and Album
- Added cachedArtists/cachedAlbums getters to LibraryStore
- searchLibraryCache now includes MBIDs and local cover art URLs
so library results can navigate to explore detail pages
- Added mergeWithLibrary() — when full MB results arrive, library
entries are enriched with local images and 'In Library' flags
rather than being replaced by MB-only versions
- Created ExploreCache store for cross-page data sharing: search
results populate the cache, detail pages can read from it to
avoid redundant API calls for already-fetched data
Complete rewrite of the artist image pipeline:
STORAGE:
- Migration 16: artist_images table tracking source, URL, path,
primary flag, dimensions per image (up to 10 per artist)
- Directory structure: artist-images/{mbid[:2]}/{mbid}/ with
primary.jpg + primary_sm.jpg/_md.jpg/_lg.jpg thumbnails
- Miss marker (.miss file) prevents re-fetching artists with no image
SOURCES (priority order):
1. MusicBrainz direct image relations (Wikimedia Commons)
2. Wikidata P18 property (Wikimedia Commons)
3. Wikipedia lead image (NEW — via Wikidata sitelinks → Wikipedia API)
Each source is checked, deduplicated, and the first available
image becomes the primary with sm/md/lg thumbnail generation
(100px/200px/400px, matching cover art tier sizes).
ASSET SERVING:
- /artist-images/ path registered with Wails asset handler
- Serves files via http.FileServer from the artist-images directory
- Same pattern as /covers/ for cover art
ARTIST MODEL:
- Artist struct gains ImageSmall/ImageMedium/ImageLarge fields
- resolveArtistImages does bulk MBID lookup → disk stat for each
- Populated in GetAllArtists and GetAllArtistsByLibrary
GRID VIEW:
- artists-view uses model URLs directly (no more base64 data URLs)
- Size selection based on imageSize * devicePixelRatio (like cover-grid)
- Removed batch GetArtistImages call and in-memory cache — no longer needed
Migration 15: add in_library and is_similar INTEGER columns to
explore_index. Backfills in_library from existing library MBIDs.
Search index FTS5 query now includes personalization in scoring:
ORDER BY bm25(...) - (ln(pop+1) * 1.5)
- (in_library * 3.0) - (is_similar * 1.5)
For equal text+popularity scores:
- Library artist beats unrelated by 3.0 points
- Similar artist beats unrelated by 1.5 points
- Library > Similar > Neither
Tier 3 (library) entries get in_library=1 via markInLibrary.
Tier 4 (similar) entries get is_similar=1 via markSimilar.
MB result reranking (boostWithIndexPopularity) adds a 10M
popularity bonus for library artists, ensuring they always
rank above non-library artists with equal text relevance.
Migration 14: add aliases TEXT column to explore_index, rebuild FTS5
with 3 columns (title, artist_name, aliases), recreate sync triggers.
Clears index build timestamps to force alias population on next build.
Artist image provider fetches inc=url-rels+aliases (single call, no
extra cost). GetAliases() extracts alias names from cached MB rels.
indexOneArtist stores aliases as space-separated text after image
resolution populates the cache.
Search query now uses BM25 blended scoring:
ORDER BY bm25(fts, 3.0, 1.0, 0.5) - (ln(popularity+1) * 0.5)
Column weights: title=3.0, artist_name=1.0, aliases=0.5
- Title matches score 3x higher than artist name matches
- Alias matches are helpful but don't dominate
- Popularity is a log-scaled boost, not an override
- Exact title match on niche entity beats weak match on mega-popular
Enables: 'rhcp' → Red Hot Chili Peppers, 'gnr' → Guns N' Roses,
'sabbath' → Black Sabbath (once index build runs with aliases).
Three features wired together:
1. 'In Library' badges on explore search results:
CheckLibraryMBIDs Wails binding batch-checks which search result
MBIDs exist in the local library. Green badges render on matching
artist cards and album cards.
2. Artist images on local artist-details page:
Local artist pages now call GetArtistMBID(name) to resolve the
MBID from tags, then GetArtistImageURL(mbid) to fetch the cached
Wikimedia photo. Falls back to initial-letter avatar.
3. Tier 3 search index uses direct MBIDs from tags:
buildTier3Library now reads artists.mbid column (from audio tags)
for direct MBID matching, falling back to name matching for
untagged artists. Eliminates false matches and catches artists
that name matching misses.
Add nullable TEXT mbid column to artists, release_groups, and
recordings tables. Partial indexes on each (WHERE mbid IS NOT NULL)
for fast MBID lookups without bloating the index for rows without
MBIDs.
Enables linking local library entities to MusicBrainz/ListenBrainz
explore data, artist image sharing, and 'In Library' badges.
Add explore_index table (entity_type, mbid, title, artist_name,
artist_mbid, popularity, extra_json) with a unique index on
(entity_type, mbid). FTS5 virtual table explore_index_fts backed
by the content table with auto-sync triggers for insert/update/delete.
explore_index_meta table tracks build timestamps.
COALESCE(last_played, '') returned empty string which can't scan into
time.Time. Removed COALESCE, use sql.NullTime instead. Format to string
only when Valid.
Backend:
- GetAllTracksWithFullMetadata queries now select play_count and last_played
- mapTrackRow accepts and passes through PlayCount/LastPlayed
- PlayCount + LastPlayed added to library.Track struct
- sqlcgen Row types updated with new fields
Frontend:
- PlayCount + LastPlayed added to library.Track TypeScript model
- 'Plays' column added to track-list column definitions (60px, right-aligned, sortable)
Queries without play data (search, genre, album) pass 0/empty defaults.
Migration 10:
- play_history table (audio_file_id FK, played_at DATETIME, CASCADE delete)
- play_count + last_played columns on audio_files (denormalized)
- Recreated track_metadata VIEW with play_count and last_played columns
Play recording:
- queue.recordPlay() inserts play_history row + updates denormalized columns
- Called from OnPlaybackFinished after queue advance completes
- Mutex released before DB write to avoid MaxOpenConns(1) deadlock
- Natural finish only — skip/stop does not count
Tests:
- TestMigration10PlayHistory: schema, columns, VIEW, round-trip verification
- All 49 smart playlist + 15 service + existing DB tests still pass
- Add phantom_file_path column to playlist_tracks (migration 7)
- Store original file_path during RemoveLibrary phantom metadata population
- After each successful scan, UPDATE phantom tracks whose phantom_file_path
now matches an audio_files row, re-linking them and clearing phantom metadata
- Update schema file, sqlc generated code, and database test for new column
- GetAllTracksWithFullMetadataByLibrary for tracks filtered by library
- GetAudioFilesByReleaseGroupByLibrary for album tracks in a library
- GetAllAlbumsWithDetailsByLibrary for albums with tracks in a library
- GetAlbumsByArtistByLibrary for artist albums in a library
- GetAlbumArtistsByLibrary for artists with albums in a library
- GetAllGenresWithCountsByLibrary for genre counts within a library
- GetTracksByGenreByLibrary for genre tracks within a library
Task 1: Schema, events, and progress types
- Add library_id to CreateAudioFile SQL INSERT and regenerate sqlc code
- Add LibraryScanQueued and LibraryScanQueueDrained event constants
- Regenerate TypeScript events via genevents
- Add LibraryID, LibraryName, QueuedCount to ScanProgress
- Add LibraryID, LibraryName to ScanMetrics
- Add libraryID field to importResult for threading through pipeline
Task 2: Scan queue coordinator and per-library scanning
- Create scan_queue.go with ScanLibrary(id), ScanAllLibraries()
- Add CancelCurrentScan(), CancelAllScans() for queue-aware cancellation
- FIFO scan queue with silent dedup (same library already scanning or queued)
- Refactor Scan() -> scanInternal(libraryID, libraryName, libraryPath)
- Replace GetAllAudioFiles with GetAudioFilesByLibrary for per-library loading
- Thread libraryID through DB writer to set CreateAudioFileParams.LibraryID
- drainQueue auto-starts next queued library or emits LibraryScanQueueDrained
- Pause freezes current scan AND queue
- Add GetScanQueueLength() and QueuedLibraryNames() for UI
- Mark CancelScan() and Scan() as deprecated
On existing databases, CREATE TABLE IF NOT EXISTS audio_files is a no-op
but the standalone CREATE INDEX on library_id would fail because the
column doesn't exist until migration 6 runs. The migration already
creates this index, so removing it from the schema file is correct.
- Add backupDatabase() for timestamped .db file backup before migration
- Add migration6MultiLibrary() with all 14 steps: FK OFF, create libraries table,
insert default library from TOML config, add library_id to audio_files, rebuild
playlist_tracks with SET NULL FK and 6 phantom columns, backfill phantom metadata,
recreate track_metadata VIEW with library_id, FK ON, clean TOML config
- Add readLibraryDirFromTOML() and removeLibraryDirFromTOML() helpers
- Update runMigrations signature to accept dbPath for backup
- Add sentinel library row in NewTestDB for FK constraint satisfaction
- Create _libraries.sql with libraries table (name, path, created_at)
- Add library_id FK column and index to audio_files.sql
- Update playlist_tracks.sql with nullable audio_file_id, SET NULL FK, and 6 phantom columns
- Add af.library_id to track_metadata VIEW
- Regenerate sqlc code for updated schemas
- Fix playlist.go to use sql.NullInt64 for nullable audio_file_id
- Fix errcheck for db.Close() in testhelper.go
- Fix errcheck, nlreturn, wsl, gofumpt issues in genevents/main.go
- Fix gofumpt and wsl issues in library.go
The GetAudioFilesByReleaseGroup SQL query only selected 6 columns,
missing audio properties (sample_rate, bit_depth, channels, bitrate,
file_size) and metadata (album, genre, year, composer, file_type).
This caused track details opened from the album view to show dashes
instead of actual values. Expanded the query to match
GetAllTracksWithFullMetadata and updated GetAlbumTracks to use the
shared mapTrackRow helper.
The search_index is a contentless FTS5 table (content=''), which
SQLite does not support DELETE on. ClearSearchIndex now drops and
recreates the virtual table. Single-row DeleteSearchIndex becomes
a no-op since contentless FTS5 also cannot delete individual rows;
stale entries are harmless (search JOINs filter them out) and the
index is fully rebuilt during FullRescan.
- Migration 5 rebuilds release_groups with UNIQUE(name, album_artist_credit_id)
- Drops and recreates track_metadata VIEW during table rebuild
- Temporarily disables FK checks for safe table rebuild
- Entity cache now keys by album name + artist credit ID
- Update tests to use composite cache keys
- Change UNIQUE(name) to UNIQUE(name, album_artist_credit_id) in schema
- Update UpsertReleaseGroup ON CONFLICT to match composite key
- Rename GetReleaseGroupByName to GetReleaseGroupByNameAndArtist with two params
- Regenerate sqlc code
- 7 SAFETY comments in search.go (FTS5 MATCH/INSERT/DELETE operations)
- 3 SAFETY comments in library.go (FTS5 INSERT/DELETE in commitNewAudioFile, updateAudioFileMetadata)
- 1 SAFETY comment in rescan.go (FTS5 DELETE in clearAllLibraryData)
- 1 SAFETY comment in persistence.go (variable-count multi-row INSERT)
- Cross-references link library.go/rescan.go back to search.go
- Two-part format: why sqlc can't handle it + what makes it safe
- Add LookupTrackMetaByPaths sqlc query using track_metadata VIEW with sqlc.slice()
- Replace hand-crafted fmt.Sprintf IN clause in lookupChunk with sqlc-generated call
- Preserve lookupTrackMetaBatch chunking at maxSQLiteVars (900)
- All queue tests pass with -race
