111 of 122 top-level src/utils/ files move into 16 topic folders (audio,
cache, cover, share, server, playback, playlist, deviceSync, waveform,
mix, format, export, changelog, ui, perf, componentHelpers). True
singletons with no cluster stay at the utils/ root.
Pure file-move: a path-aware codemod rewrote 539 relative-import
specifiers across 275 files; no logic touched. The hot-path coverage
gate list (.github/frontend-hot-path-files.txt) is updated to the new
paths for the 11 gated utils files — a mechanical consequence of the
move, not a CI change. tsc is green.
Four-cut cluster opening the Playlists refactor. 1039 → 763 LOC
(−276).
playlistsSmart — full smart-playlist module: SMART_PREFIX /
LIMIT_MAX / YEAR_MIN / YEAR_MAX constants, GenreMode / YearMode /
SmartFilters / PendingSmartPlaylist / NdSmartRuleNode types,
defaultSmartFilters seed, clampYear / isSmartPlaylistName /
displayPlaylistName / asRecord helpers, parseSmartRulesToFilters
(the Navidrome JSON rule walker), and buildSmartRulesPayload (the
reverse — page-state → Navidrome JSON). The payload builder
becomes parameterized on the filters object so it lives outside
the component.
PlaylistCoverImages — two tiny CachedImage wrappers
(PlaylistSmartCoverCell for the 200 px collage cells,
PlaylistCardMainCover for the 256 px main card cover).
useSmartCoverCollage — replaces the inline useEffect that builds
the 2×2 cover collage for each smart playlist (pulls playlist
tracks, filters to active library scope, collects up to four
unique cover-art ids). Returns the per-playlist id map and
re-fetches on playlist list change or library filter version bump.
usePlaylistsLibraryScopeCounts — replaces the inline useEffect
that recomputes per-playlist song count + total duration under
the current library scope. Chunked into batches of four parallel
fetches.
Playlists drops the inline definitions; pure code move otherwise.
