An event carries what a consumer needs so it never has to invalidate.
- `library-store` answers `TrackPlayCountChanged` by patching one
track, replacing the tracks array (consumers key memoized caches on
its identity) while sharing every unchanged Track — instead of
discarding four collections and refetching 25 MB per song.
- `playlist-store` answers `PlaylistTracksChanged` by refetching the
one playlist the event names, plus the summaries, since `UpdatedAt`
is a sort key. 2 668 kB and 172 ms for one heart, against 2.0 kB. It
falls back to a full invalidate only where a patch cannot be shown
to be equivalent: no id, a cold cache, an unknown id, or a fetch
already in flight. And a store with no subscriber fetches nothing —
the singleton's constructor used to put every track of every
playlist on the path to first paint for a view the user might never
open.
- `library-store` guards every fetch with a cache generation and holds
the request itself instead of deriving a promise from subscriber
notifications, which fixes the library-filter race and the
never-settling waiter together: they are the same bug seen from
either end.
- `explore-cache`'s two art caches are bounded, sharing one exported
cap constant — the artist photo's data URL is held by both, so
capping either alone frees nothing at all and reads as a fix that
did not work.
- `search-store` deliberately does *not* coalesce its notify: deferring
makes a subscriber that unsubscribes synchronously after a `setTerm`
miss the notification entirely, which is a semantic change rather
than an optimisation, and this is the store on the keystroke path.
- `selection-controller` retains its keys across a refetch rather than
clearing them, since they are file paths and those survive one, and
`getSelectedKeysOrdered()` gains an early exit. It stays a walk of
the list: an index goes stale on any re-sort, re-filter or refetch
while a file path survives all three, and 3 ms does not buy a
silently mis-ordered queue insert.
There was no app-level notification surface: two components had grown
private toasts and the other 84 catch blocks ended at console.error,
so a user with a moved file, a locked database or an offline network
saw a button that did nothing. Where errors did surface, eight sites
printed the raw Go string.
Four levels, chosen by the call site from one rule — a failure is only
worth interrupting for if the user can do something about it that they
are not already doing: Blocking (data at risk), Persistent (something
asked for that did not happen, worth retrying), Transient (a small
action whose state visibly reverted anyway), Inline (rendered in the
panel that failed).
Three things about it are load-bearing. Coalescing lives in the store,
keyed by (level, region, key) within a window, so 200 unplayable files
are one message with a count and no future caller has to remember that.
An inline notification carries a *region*, because "inline" says not
global, not where. And the bottom band belongs to the player, so the
app-level stack sits under the header — the player's own floating
notice grows upward by however many lines it needs.
`utils/describe-error.ts` maps the causes a user can act on to copy;
`explainError` repeats a backend message when it is one of our own
sentinels rather than a Go wrapping chain, since mapping "a library
with that name already exists" to something generic is a regression.
`confirmAction()` is a wa-dialog, so destructive actions inherit the
focus trap and Escape the hand-rolled overlays do not have.
`index.ts` caches primary views and hides them with a class so
scrollTop survives navigation. Nothing else was told: `disconnectedCallback`
never fires for one, so everything written to clean up there never
cleans up. The worst case was not a leak — pressing `s` on Settings
skipped two albums out of the Autotag queue, and `a` on that same live
handler rewrites tags on disk.
- `utils/view-lifecycle.ts` is the missing half: `viewActivated` /
`viewDeactivated`, with `listenWhileActive`, `intervalWhileActive`
and `whileActive` torn down on the way out, and an off-screen view
that does not render. `registerViewAware` gives a shared reactive
controller the same treatment, because a controller cannot know
whether its host is a cached view — `ContextMenuController` bound
three document listeners in `hostConnected`, which for a cached host
is "forever".
- `services/shortcut-scope.ts` publishes the ambient scope. Resolving
scope from focus alone was not enough: this app is driven with the
mouse, focus sits on `<body>`, and a focus-only rule would have made
the panel keys work only after a click landed inside the panel.
- Global bindings yield to a focused control that owns the key —
button, select, slider, checkbox, menu, grid row, or anything inside
an open dialog — so the unmodified single-key bindings stop stealing
Space and the arrows.
- `utils/roving-grid.ts` gives a card grid one tab stop moved with the
arrows, since a card per tab stop makes a library-length tab
sequence.
Muting does not change the volume level, and VolumeChanged carried
nothing but that level — so pressing M silenced playback and left the
indicator showing the volume it still had. The UI had nothing to react
to.
Mute rides on its own event rather than widening the volume payload,
since the two are genuinely independent: a muted player at 40% is a
different state from a player at 0%, and only one of them comes back
when you unmute. The icon crosses out and dims, and the popup gains an
explicit Mute/Unmute so the keyboard shortcut is not the only way in.
MuteToggle also now takes the speaker lock (it was mutating the effects
chain from outside it) and refuses politely rather than dereferencing a
nil streamer when nothing has been loaded yet.
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.

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.

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
The HTTP endpoint approach still crashed due to Wails asset server
issues. Replaced with a pure frontend solution: searchLibraryCache()
does a substring match against the libraryStore's cached artists and
albums arrays. This is pure JS — zero Go calls, zero RPC, zero
network — guaranteed instant.
Results appear immediately as the user types. The full MB+LB search
pipeline still runs via Wails RPC and replaces the library matches
with richer results when done.
Added cachedArtists/cachedAlbums getters to LibraryStore for
synchronous read-only access to the already-loaded data.
Removed the /api/search-local HTTP handler from the backend.
- LibraryStore now listens for TrackMetadataChanged and invalidates all caches
- Track Details context menu item visible for any right-clicked track in all 4 views
- Removed selectionCount === 1 gate from track-list, queue-panel, cover-grid, playlist-details
- Replace wa-icon shadow DOM with inline SVG in queue-panel (xmark)
and album-dropdown (fav icons) to eliminate per-item shadow roots
- Memoize getBeforeEntries/getAfterEntries in cover-grid to prevent
.slice() creating new array refs that trigger virtualizer relayout
- Remove transition: scale and border-radius from album cards to
avoid per-frame repaints and anti-aliased path clipping
- Add queueMicrotask batching to player-store and favorites-store
notify() to coalesce rapid-fire updates into single renders
- Queue store now uses queueMicrotask batching (matching library store pattern)
- Library store adds changeGeneration counter incremented only on actual data changes
- LibraryController checks changeGeneration before requestUpdate, skipping loading-only transitions
- Reduces unnecessary component re-renders during data loading cycles
- New playlist-details component with header (back button, playlist icon, title, track count)
- Full track list with all interactions: select, play, context menu, drag, phantom handling
- Drop target support for adding tracks from other views
- Search filtering for tracks within the detail view
- Navigation routing in index.ts for playlist-details view
- Added playlist-details to SEARCHABLE_VIEWS in search-store
- Create keyboard-shortcut-service.ts singleton with keydown listener
- Shadow DOM active element resolution for scope detection
- Text input suppression (only Escape passes through)
- Scope resolution: text-input > panel-specific > global
- Action dispatch to player/queue stores and Wails bindings
- Create shortcuts-store.ts with Wails persistence and event sync
- Create shortcuts-controller.ts for Lit component integration
- Export store and controller from store/index.ts
- Replace hardcoded Ctrl+F handler in index.ts with service
- Initialize service via import in frontend/index.ts
- Library store notify() coalesces multiple calls per microtask tick into one subscriber notification
- Search input debounces store propagation by 150ms while keeping instant visual feedback
- Empty search input clears immediately for responsive UX
- Remove eagerFetch() call from LibraryStore constructor
- Add deferEagerFetch() that waits for DOMContentLoaded event
- App shell renders before backend data roundtrips begin
- All 4 data types (tracks, albums, artists, genres) still loaded eagerly
- invalidate() still calls eagerFetch() directly for post-scan refresh
- Add pinDefault state, getter, setter to favorites-store
- Add pinDefault getter and setPinDefault to favorites-controller
- Update sortedEntries in playlist-view to pin default playlist to top
- Add Pin to Top toggle in config page Favorites section
- Add Wails bindings for GetPinDefaultPlaylist/SetPinDefaultPlaylist
- React to PinDefault in FavoritesConfigChanged event payload
album artist gets populated with artist as fallback (frontend also uses
this as display name fallback for albums). added scroll position
persistence when switching main views. also added frontend cache for
faster switching.
