The frontend moves left the subsystem docs pointing at pre-campaign locations.
Update the src/CLAUDE.md key-files table + prose and the test/README.md examples
to current homes: playerStore/playAlbum -> features/playback, Track model +
songToTrack -> lib/media, sidebar -> features/sidebar, QueuePanel ->
features/queue, CachedImage/TooltipPortal/CustomSelect -> ui/, toast -> utils/ui,
subsonic/i18n -> lib, App.tsx split into app/{MainApp,AppShell,RequireAuth}.
Docs only; no code touched.
songToTrack (the canonical Subsonic-song -> Track mapper) and the pure
server-scope helpers (activeServerProfileId, stampTrackServerId/s,
isMultiServerQueue, profileIdFromQueueRef) operate only on the lib/media model +
authStore + server-key utils -- no playback-store read. Move them to lib/media so
the ~58 app-wide consumers (cover, context menus, sharing, lucky-mix, library
browse, pages, hooks) depend on lib, not on the playback feature.
trackServerScope is split: the store-reading queue helpers (queueItemRefAt,
filterQueueRefs*, activeServerQueueTrackIds) stay in
features/playback/utils/playback/trackServerScope and build on the pure lib half.
With Track/QueueItemRef (prior commit), songToTrack and shuffleArray now in lib,
the media-domain model is fully out of features/playback. The remaining
playerStoreTypes imports are PlayerState only (the store shape). tsc 0, lint 0,
full suite 2353/2353, build OK.
Track is the app's normalized song model and QueueItemRef its thin queue
identity -- consumed app-wide (queue, cover, context menus, sharing, lucky-mix,
library browse), not a playback-internal detail. They lived in
features/playback/store/playerStoreTypes, forcing ~115 core/feature files to
reach into the playback feature for the central media type.
Move the two interfaces to lib/media/trackTypes; playerStoreTypes keeps
PlayerState and now imports them from lib. 115 importers repointed (mixed
'PlayerState, Track' lines split so PlayerState stays). Pure type move (erased at
runtime). tsc 0, lint 0.
utils/library is the local-index query/browse/sync engine -- feature-free shared
infra consumed by the album, search, genre, artist and offline features. With
its last feature edges removed (queue resolver, shuffleArray, albumBrowseCatalogChunk,
genreBrowsePlayback all relocated earlier this branch), the whole directory is
pure infra and belongs under lib/.
Whole-directory move (58 files, 76 consumers rewritten) via resolver-based
rewrite: cross-cluster relatives absolutized to @/, intra-cluster siblings kept
relative. utils/library is gone; lib/library imports zero @/features. Three
stale doc comments in the album/search/artist barrels repointed.
tsc 0, lint 0, full suite 2353/2353, production build OK.
genreBrowsePlayback is a "play X" queue builder -- it turns a genre seed into a
Track[] for the player, the genre analogue of playArtistShuffled which already
lives in features/playback/utils/playback. Consumed only by the 3 genre pages,
by no utils/library sibling, so the whole-file move is clean (no split). Its
Track/songToTrack edges become intra-feature; its remaining utils/library
siblings (advancedSearchLocal, albumBrowseSort, genreCatalogCountsCache,
genreAlbumBrowse, libraryReady) are plain infra deps.
utils/library now has ZERO @/features importers (source AND tests) -- the bulk
is ready to relocate to lib/library. tsc 0, lint 0, genre suite green.
shuffleArray is a pure generic Fisher-Yates over T[], misfiled in
features/playback. Move to lib/util (next to dedupeById): fixes the existing
core->feature edges (utils/componentHelpers/*) and drops one of
genreBrowsePlayback's playback deps.
albumBrowseCatalogChunk is the feature-layer orchestrator that picks the offline
branch on top of the pure lib catalog loaders; its sole consumer lives in
features/album and its offline dep is a legal feature->feature edge there. Its
.test.ts stays in utils/library -- that test exercises fetchLocalAlbumCatalogChunk
from albumBrowseLoad (misnamed), which is not moving.
utils/library now has a single remaining feature importer: genreBrowsePlayback
(songToTrack + type Track), blocked on the Track domain model living in
features/playback. tsc 0, lint 0, targeted suites green.
The queue-resolver family (queueTrackResolver, queueRestore, queueItemRef,
queueTrackView) runtime-imports usePlayerStore / playerStoreTypes — it is the
playback engine's thin-state queue subsystem, not shared library infra. It sat
in utils/library only because it queries the local index. Co-locate into
features/playback/store so those edges become intra-feature; its remaining deps
(advancedSearchLocal, libraryReady, serverLookup, serverIndexKey, authStore) are
plain core/infra (feature -> infra, no inversion).
Removes 4 of the 6 store/utils -> feature runtime inversions that blocked the
utils/library -> lib move. 8 files moved, 46 consumers rewritten. tsc 0, lint 0,
targeted suites green.
Relocate the playback/queue/transport/audio-output engine out of the type-first
store/ + utils/playback/ + utils/audio/ dirs into a cohesive src/features/playback/,
structure-preserving:
store/<x> -> features/playback/store/<x>
store/audioListenerSetup/<x> -> features/playback/store/audioListenerSetup/<x>
utils/playback/<x> -> features/playback/utils/playback/<x>
utils/audio/<x> -> features/playback/utils/audio/<x>
184 files moved (107 source + 77 tests), 365 consumers rewritten. Pure move — no
behavior change, no state-split (the playerStore state-split stays a separate M5
question). Enabled by this session's decouple seams (artist/offline/orbit/auth →
core registries), so the engine carries no inbound core->feature inversion: store/
now holds only the 50 cross-cutting global stores (auth family, the seams, library
index, UI/settings stores).
KEPT OUT of the move (would re-create global->engine edges): the 3 pure config
helpers utils/audio/{loudnessPreAnalysisSlider,hiResCrossfadeResample} +
utils/playback/autodjOverlapCap (authStore + settings UI read them — they stay in
utils/). Ambiguous view-state stores (eqStore, queueToolbarStore,
playerBarLayoutStore) stay global (no engine imports).
Consumers use DEEP paths (@/features/playback/...), no barrel — matches the lib/
approach and avoids barrel-mock-collapse across the 140 usePlayerStore consumers.
Two tolerated type-only core->feature edges remain (localPlaybackStore->QueueItemRef,
localPlaybackMigration->HotCacheEntry, both erased).
tsc 0, lint 0, full suite 319/2353 green, iron-rule clean (no runtime store->feature
import). Behavior-touching only via the prerequisite bridge seam (already QA-flagged);
the move itself is pure.
The last core→engine inversions blocking the playback-core move live in the
authStore settings/profile family: authServerProfileActions reads
usePlayerStore.queueServerId + calls clearQueueServerForPlayback (on server
delete), and authAudioSettingsActions calls
usePlayerStore.updateReplayGainForCurrentTrack from ~8 ReplayGain/normalization
setters. Both are re-exported through the authStore barrel, so a global store
would depend on the (soon-to-move) engine.
Add core seam store/playbackEngineBridge.ts: a registry exposing getQueueServerId
/ clearQueueServerForPlayback / updateReplayGainForCurrentTrack with no-op/null
defaults. The engine registers its impls via store/playbackEngineBridgeRegister.ts
(side-effect-imported by MainApp at boot). authStore actions now call the neutral
delegators instead of importing the engine.
Default is safe: the only callers are user-triggered settings/profile actions that
fire long after boot (engine already registered); at boot there's no current track
or queue binding, so the no-op would be correct anyway. authStore.servers.test
imports the register module so removeServer's queue-clear runs through the real
engine wiring.
Prepares the playback-core move (Engine → features/playback): with this + keeping
the 3 config-helper utils in utils/ + tolerating 2 type-only edges, the engine has
no inbound core→feature inversions left. tsc 0, lint 0, suite 319/2353 green.
Behavior-touching (server-delete queue clear, settings→gain refresh) → Frank QA.
Add core seam store/orbitRuntime.ts: a registry (registerOrbitRuntime) exposing a
neutral session snapshot {role,phase,state} + an async bulkGuard, plus pure
derivations mirrored from the feature (isInOrbitSession, isOrbitPlaybackSyncActive,
estimateLivePosition). Default (unregistered) = neutral snapshot + bulkGuard allow
— bit-identical to today's no-session behavior, and a session can only start via
the topbar which loads the @/features/orbit barrel (→ registers) first.
features/orbit/utils/orbitBulkGuard registers the runtime at module init
(store-backed getSnapshot + the existing confirm-modal orbitBulkGuard as the gate).
The orbit feature keeps its own copies of the pure helpers for UI (incl. the
arg-form isOrbitPlaybackSyncActive(role,phase) used by two settings/player-bar
components), so nothing UI-facing changes.
Repointed the 9 audio-core sites (playbackRateStore, previewStore,
playbackReportSession, nextAction, resumeAction, playTrackAction,
queueMutationActions, playAlbum) from @/features/orbit to @/store/orbitRuntime;
state reads (useOrbitStore.getState().role/.state) become orbitSnapshot().
Migrated 6 audio-core test mocks to @/store/orbitRuntime via importOriginal-spread
(keeps registerOrbitRuntime callable). enqueueShareSearchPayload stays on the orbit
barrel (share util, not audio core) — its test mock unchanged.
Decouple Step 3 — last seam. The audio ENGINE is now free of @/features/* runtime
imports (only type-only edges + the non-engine composerBrowseSessionStore browse
store remain). Unblocks the playback-core move + utils/library→lib.
tsc 0, lint 0, full suite 319/2353 green.
NEEDS Frank's live-session QA before relying on it (host+guest bulk-replace modal,
guest catch-up, rate/preview/scrobble suppression).
Add core seam store/mediaResolver.ts: a registry (registerMediaResolver) with
delegating resolveAlbum/resolveArtist/resolvePlaylist + the pure auth wrappers
resolveMediaServerId/resolveAlbumForActiveServer/resolveAlbumForServer and the
ResolvedAlbum type. Default (unregistered) = network-only safety net (no
library-index/offline branch — those stay in the feature).
features/offline/utils/offlineMediaResolve keeps the offline-aware policy impls
and registers them at module init (registerMediaResolver). The call runs at boot:
AppShell eagerly imports the @/features/offline barrel, whose export * evaluates
offlineMediaResolve. The 3 thin wrappers + ResolvedAlbum move to the core seam and
are re-exported from offlineMediaResolve so the offline barrel still surfaces them
for the ~25 UI consumers (unchanged).
Repointed the 5 audio-core call sites (fetchTracksForSource, playAlbum,
playArtistShuffled, playByOpaqueId, luckyMixHelpers) from @/features/offline to
@/store/mediaResolver. Migrated playAlbum.test's mock to the new module via
importOriginal-spread (keeps registerMediaResolver callable when the offline
barrel loads transitively — partial-mock-collapse otherwise).
Decouple Step 2b. The audio core's only remaining @/features/offline reference is
now the type-only localPlaybackMigration import (erased). Runtime offline edge gone;
orbit seam (Step 3) remains.
tsc 0, lint 0, full suite 319/2353 green.
Pull findLocalPlaybackUrl/findLocalPlaybackEntry/hasLocalPersistentPlaybackBytes
+ the entry/index-key membership helpers (entryBelongsToServer,
indexKeyBelongsToServer, findFavoriteAutoEntry, hasLocal{Library,FavoriteAuto}Bytes)
out of features/offline/utils/offlineLibraryHelpers into a new core module
store/localPlaybackResolve.ts. The substrate depends only on authStore +
localPlaybackStore + serverIndexKey utils (no useOfflineStore), so the audio
core can resolve on-disk bytes without inverting into @/features/offline.
Repointed the audio-core consumers (crossfadePreload, playbackUrlRouting,
resolvePlaybackUrl, playTrackAction, promoteStreamCache, hotCachePrefetch,
hotCacheStore) + offline-internal callers + favorites hook; moved the two
barrel vi.mocks onto the new leaf module. offlineLibraryHelpers re-imports the
two primitives it still needs internally.
Decouple Step 2a. Removes the local-bytes offline edge from the audio core;
the resolve* media-resolution family (Step 2b) + orbit seam (Step 3) remain.
tsc 0, lint 0, full suite 319/2353 green.
First step of decoupling the audio core from feature imports. coerceOpenArtist
Refs is a pure Subsonic-response normalizer (one-object-vs-array quirk) that was
mis-membered in features/artist but consumed by the audio core (songToTrack,
trackArtistRefs) and others. Relocate it beside its SubsonicOpenArtistRef type in
lib/api/; drop the artist-barrel re-export; repoint the 4 barrel consumers.
Removes the @/features/artist runtime edge from the audio core (utils/playback)
entirely. tsc 0, lint 0/0, suite 319/2353 green.
(composerBrowseSessionStore's ALL_SENTINEL import from @/features/artist remains
— that's a non-audio global browse store, separate from this decouple.)
The shortcut contract (shortcutActions.ts + shortcutTypes.ts) is NOT a
pure-frontend file: src-tauri/src/cli/parse.rs include_str!s
'/../src/config/shortcutActions.ts' at compile time, so moving it to
lib/shortcuts/ (slice 7ad19671) broke the Rust build (couldn't read the file ->
dev build won't start). Revert the contract back to src/config/ — it has a
build-time backend path contract and belongs where Rust anchors it, not in lib/.
No Rust file touched (fix = restore the frontend path the backend expects).
cargo check green (13s), tsc 0, lint 0/0, frontend suite 319/2353 green.
Lesson: grep src-tauri for include_str!/include_bytes! '../src/...' before
moving ANY frontend file — Rust can pin a TS file by path.
Extract the queue UI (QueuePanel + queuePanel/* components + useQueue* hooks)
into features/queue/ with a barrel. This is the chosen playback/queue boundary:
queue = the QueuePanel UI that CONSUMES the playback store; queue STATE and the
audio engine stay in store/ (playback-core, moved separately). Verified
one-way: no playback-core file imports the queue UI back (only doc comments
mention it).
Excluded as NOT queue-UI: useIdlePlayQueuePull (AppShell) and
usePlayQueueSyncLedState (ConnectionIndicator) are queue-SYNC orchestration,
not panel UI — left in hooks/ to move with playback.
Pure move. One test fix: QueuePanel.test.tsx reads its subject via a hardcoded
readFileSync('src/components/QueuePanel.tsx') path (architecture-pin grep for
forbidden HTML5 DnD) — repointed to the new location (the move tool can't
rewrite non-import string paths). tsc 0, lint 0/0, suite 319/2353 green.
Continue M4 lib/ de-flattening with domain-agnostic infra:
- lib/hooks/: 9 pure generic hooks (useDebouncedValue, useIsMobile,
useLongPressAction, useRangeSelection, useResizeClientHeight,
useWindowVisibility, useSystemPrefersDark, useVirtualizerScrollMargin,
useRemeasureGridVirtualizer) — all PURE (only react/zustand/tanstack deps).
- lib/dnd/DragDropContext.tsx: the generic mouse-event DnD engine (WebKitGTK
HTML5-DnD workaround, ~24 importers, self-contained) — empties src/contexts/.
- lib/shortcuts/: shortcutActions + shortcutTypes (the action-id + binding
contract; registry/dispatch/bindings stay app-level and import the contract,
app->lib direction).
useWindowFullscreenState deliberately NOT moved — kept in hooks/ as app-shell
per the handoff iron-rule list (overrides its pure-helper appearance).
Pure move via deep @/lib/* specifiers. tsc 0, lint 0/0, full suite 319 files /
2353 tests green.
Move domain-agnostic, feature-free helpers out of the flat utils/ and store/
roots into src/lib/ (plan M4, §3 lib/ layer):
- lib/format/: formatBytes, formatClockTime, formatDuration, formatHumanDuration,
relativeTime (pure format/date/byte/clock helpers)
- lib/i18n.ts: i18next bootstrap (global app infra)
- lib/util/: sanitizeHtml, platform, dedupeById, safeStorage (pure helpers +
the zustand storage adapter)
playbackScheduleFormat stays in utils/format (runtime usePlayerStore dep =
audio-core coupling, not generic). formatClockTime keeps a type-only
@/store/authStoreTypes import (erased, no runtime inversion — accepted per the
deviceSync precedent).
Pure move via deep @/lib/* specifiers (no barrel → no mock-collapse surface).
tsc 0, lint 0/0, full suite 319 files / 2353 tests green.
Tooling note: lib_move.py regex extended to also rewrite side-effect imports
(import './i18n') and vi.importActual paths — both were silent gaps.
Move the 5 subsonic api modules that M3 had co-located into features
(subsonicAlbumInfo/Artists/Playlists/Radio/Statistics) into src/lib/api/, the
feature-free infra layer, and drop their feature-barrel re-exports. Consumers
now import these protocol calls directly from @/lib/api/subsonic*; the feature
barrels export only domain UI/hooks/state.
This is the consistent api placement (plan §10.3, revised: ALL subsonic protocol
clients are feature-free infra, not per-feature) and it kills the documented
api-induced feature<->feature cycles: offline->artist/playlist (getArtist/
getPlaylist*), album->artist (getArtistInfo), deviceSync/nowPlaying/orbit->*.
Remaining artist<->album refs are UI-only (OpenArtistRefInline/coerceOpenArtist
Refs) and offline->playlist is store-level (usePlaylistStore) — both deeper,
tracked for M5, not api placement.
Pure move: import specifiers + vi.mock/spy targets repointed; no behaviour
change. tsc 0, lint 0/0, full suite 319 files / 2353 tests green.
Tooling note: barrel-imported and dynamic-import api symbols were split out of
@/features/* to @/lib/api/* (tsc-driven); 12 vi.mock barrels retargeted to the
deep lib module (mock-collapse sweep), AlbumHeader's UI mock left untouched.
Move the Subsonic + Navidrome protocol clients and the library IPC facade
(subsonic*, navidrome*, library.ts + tests) from src/api/ into src/lib/api/,
the feature-free infra layer (plan M4, decision §10.3: shared client core → lib/).
Pure move: deep-path import specifiers @/api/* -> @/lib/api/* across ~150
consumers; no behaviour change. Domain REST (lyrics/events) and cover/analysis
infra stay in src/api/ pending their own M4 placement.
tsc 0, lint 0/0, full suite 319 files / 2353 tests green.
The album barrel reaches genreBrowsePlayback.test's transitive graph through the
artist↔album edge (songToTrack → @/features/artist → @/features/album →
useGenreAlbumBrowse), which needs GENRE_ALBUM_FIRST_PAGE from the partially
mocked ./genreAlbumBrowse. Spread importOriginal so it stays real.
The move tool rewrote single-module mocks (e.g. vi.mock('@/utils/orbitBulkGuard'))
into feature-BARREL mocks (vi.mock('@/features/orbit', ...)). A partial barrel
factory shadows every other barrel export to undefined — and src/test/helpers/
storeReset.ts reads useOrbitStore.getState() at module load, so 6 test files
(playerStore.misc/events/queue/playbackActions, ContextMenu, QueuePanel) crashed
at collection (0 tests run, mis-read as flaky teardown). Retarget each collapsed
mock to its deep submodule so the barrel re-exports the stub while siblings
(useOrbitStore, offlineActionPolicy, usePlaylistStore) stay real.
The offline move collapsed a single-module mock into a `@/features/offline`
barrel mock, which shadowed the real `useOfflineBrowseContext` the test relied
on. Mock the reload-token submodule directly so the barrel re-exports the stub
while the sibling context hook stays live.
The M0 pilot mis-membered the waveform data pipeline into features/waveform,
creating a core->feature inversion: ~12 audio-core files in store/ imported
refreshWaveformForTrack / fetchWaveformBins / bumpWaveformRefreshGen from the
feature barrel. These are playback coordination (write waveformBins into
playerStore on track change, last-write-wins gen guard), not seekbar rendering.
Move waveformRefresh + waveformRefreshGen (+ tests) to src/store/ and
waveformParse (+ test) to src/utils/waveform/ (beside waveformSilence). The
feature now holds only the seekbar UI (WaveformSeek/SeekbarPreview + their
hooks/render utils); its barrel exports UI only. Core consumers import the
pipeline directly from @/store/*. Restores the no-core->feature-inversion rule.
Theme infra (fixedThemes, theme utils), music-network presetIcon, audio-device
probe, library-index sync, and the auth*SettingsActions slices stay in the
core/global layer (consumed via @/ alias) to avoid inverting core->feature.
