AUDIT-036 — Slider/button fixes (direct Liquid Glass cause)
scheduleFlush() now runs Task { @MainActor } instead of bare Task. The
pendingSaves dictionary is now only ever read/written on the main
thread. Before this fix, a UserDefaults write could race with a slider
didSet, causing values to snap back or write the wrong value — which
is exactly why buttons were switching state unexpectedly.
AUDIT-034 — 60fps idle Canvas (direct Liquid Glass cause)
TimelineView now uses isRenderingActive ? settings.effectiveFPS : 2.0.
When paused or not visible, the Canvas drops from 60fps to 2fps. This
stops the continuous GPU wakeups that were fighting Liquid Glass
gesture tracking, which is why sliders needed multiple attempts.
AUDIT-001 — FFT real-time heap allocation
processFFT no longer allocates any heap memory. The Hann window is
computed once in init(). All four scratch buffers (fftWindow,
fftWindowed, fftRealp/fftImagp, fftMagnitudes) are pre-allocated and
reused every render callback — zero allocations on the real-time audio
thread.
AUDIT-002 — WatchOfflineStore data race
taskToSongId and pendingSongs now protected by a dedicated serial
storeQueue. URLSession delegate reads and main thread writes are
serialised.
AUDIT-019 — URLSession per AsyncCoverArt render
CompanionAPIService() no longer instantiated per render. Companion
cover art URLs now built directly from
CompanionSettings.shared.baseURL — no URLSession created.
AUDIT-020 — Synchronous disk read on main thread
CachedImageLoader now uses memoryOnlyImage (sync, no I/O) for the
first check, then cachedImageAsync (disk read on ioQueue) for the
second. Main thread never blocks on disk I/O.
AUDIT-033 — Lost star/unstar actions offline
Star/unstar now routes through OptimisticActionQueue — actions survive
Tailscale reconnection and are retried automatically.
AUDIT-035 — OptimisticActionQueue flush race
flush() Task is now @MainActor — pendingActions only ever touched on
main thread, no more race between rapid taps and in-flight flushes.
AUDIT-038 — O(n²) deduplication
deduplicateAlbums now O(n) using a frequency dictionary. For 843
albums: ~7.1M string comparisons/second during playback → ~1,700.
AUDIT-026, AUDIT-015 — Duplicate setResourceValue removed, cacheSize
now uses totalSize directly
Companion (main.py):
• NAVIDROME_TAGS whitelist — the single source of truth for what tags
survive
• enforce_tag_whitelist() — whitelist enforcer, replaces blacklist
approach
• All 5 write points updated: apply_tags, apply_tags_dict,
upload-track, upload-tracks, restructure_all
• preserve_composer and preserve_lyrics flags on both upload
endpoints (default False)
• /library/clean-tags now uses whitelist enforcer
iOS:
• UploadMetadata — preserveComposer and preserveLyrics fields
• buildMultipartBody — sends both flags as form fields
• BatchUploadView — two toggles, both off by default, wired end-to-end
• MultiAlbumEditorSheet — full rewrite matching
BatchAlbumEditorSheet: MusicBrainz search, swipe to exclude/include
tracks, Reset button, cover art widget with red glow
Active tab — all unignored issues, swipe left → “Ignore” (grey)
• Ignored tab — all ignored issues shown dimmed, swipe left →
“Restore” (pink) to bring them back
• Fix buttons hidden on ignored issues
• Ignored IDs persisted in @AppStorage so they survive app restarts
• Tab labels show live counts: Active (1) | Ignored (31)
iOS — 6 fixes across 5 files:
Models.swift — Song, Album, AlbumWithSongs all now have albumArtist:
String?. CompanionSong.toSong() passes albumArtist.
CompanionAlbum.toAlbum() passes albumArtist to the new field.
TrackEditorView.swift — Album Artist field now initialises from
song.albumArtist ?? song.artist instead of just song.artist.
fetchCompanionDetails no longer requires companion: prefix — it
fetches for all songs using the album name, decodes properly using
CompanionLibraryResponse, and matches by relative_path.
BatchAlbumEditorSheet.swift — initialises from album.albumArtist ??
album.artist.
MultiAlbumEditorSheet.swift — pre-fills from first.albumArtist ??
first.artist.
AlbumDetailView.swift — buildAlbumWithSongs now passes albumArtist
from the companion songs.
Companion — 2 fixes:
apply_tags — now does full FLAC cleanup (removes all Picard legacy
variants) before writing, same as apply_tags_dict already did.
edit-metadata endpoint — no longer calls restructure_file. File
renaming only happens via /bulk-fix. This was the root cause of the
500 errors on compilation tracks with disc numbers.
