MemoryLogOutput extended LogOutput but was never wired as a Logger output (storage happens in the printer); DeletionNotifier/WatchStateNotifier's forServer/forItem filtered streams and WatchStateEvent.mediaType had no production consumers (tests now filter .stream directly); context.hiddenLibraries/profileSettings and toPlexUrl had zero call sites; MonoTokens.splashFactory was never read; OptimizedMediaImage's enableTranscoding/cacheKey chains, FocusableMediaCard.width/height/forceGridMode, TvBrowseRail's constant-zero gap functions, and media_image_helper's scaleFactor were never varied by any caller. The sha1 LRU stays (rebuild-hot artwork URLs); TvRailTrailing.none and the mono-theme copyWith stay live (lerp delegates to copyWith). Also carries the MusicPlayContext.id argument drops in the music screens and remaining sweep test updates.
Deduplicates the hand-rolled coalescing/caching maps, the Plex client cast,
the missing-serverId event guard and the progress-failure backoff, and drops
the MusicPlaybackService availability gate, which could never fail in
production.
Plex API returns Directory entries without type field, causing
TypeError crash in fromJson. Made fields nullable and migrated
callers to use mediaType enum and displayTitle getter instead
of raw string access.
