Per-file routing of the 9-file utils/componentHelpers grab-bag, each driven by
its verified consumer set:
- contextMenu{Actions,Helpers} → features/contextMenu/utils (sole consumer)
- queuePanelHelpers → features/queue/utils (sole consumer)
- nowPlayingHelpers → features/nowPlaying/utils; isRealArtistImage split out to
cover/ (consumed by cover/artistHero, a lower layer)
- appUpdaterHelpers(+test) + listReorder(+test) → lib/util (config/ + lib/hooks
consume them; pure)
- playlistDetailHelpers → lib/format (consumed by 3 features; pure)
- appShellHelpers → app/ (app-shell consumers only)
- userMgmtHelpers left in place: consumed by the a11y-HELD SongInfoModal, so a
move would rewrite a do-not-touch file (same block as licensesData).
Pure moves; tests pass unmodified.
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.
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.
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.
