Playback reporting (position sync / resume-on-another-device): - player_configure_jellyfin now builds a PlaybackReporter sharing the player controller's Arc, so Start/Progress/Stopped actually reach Jellyfin on every auth path (login/restore/reauth); previously they never did. - The PlaybackReporterWrapper now shares the same Arc the controller and MPV progress loop report through, instead of a dead parallel Option. - Android position callbacks now emit throttled progress reports (30s/item), mirroring the MPV backend. Duration flash on pause: - resolveDuration() prefers the live store duration for the already-loaded track over the runTimeTicks estimate, so pausing no longer clobbers the slider's max to 0 when runTimeTicks is missing. Video leaking into audio mini player: - isVideoItem() also checks the backend PlayerMediaItem mediaType discriminator, so a video started via player_play_item (no Jellyfin `type`, mediaType "video") no longer surfaces in the audio mini player. Middle-truncation of long media names: - New truncateMiddle util applied to track/episode/card/mini-player titles so distinguishing tails (episode numbers, suffixes) stay visible. Adds regression tests for the duration and mini-player fixes. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
