Opening a series dumped the viewer at the top of season 1, and its Play
button played nothing at all: it resolved `$libraryItems[0]` — the first
*season* by SortName — and navigated to `/player/<seasonId>`, which the
player route bounced straight back to `/library/<seasonId>`.
The backend could already answer "where is this viewer in this show":
`repository_get_next_up_episodes` has accepted a `series_id` since it was
written and no caller had ever passed one.
Backend (DR-101, DR-106)
- `repository/series_progress.rs`: `pick_current_episode` — in progress,
else Next Up, else first unwatched, else the premiere. The third rung is
the offline path, where Next Up is always empty. `sort_series_order` puts
specials (season 0) after the numbered seasons.
- `repository_get_series_episodes` takes over the season fan-out and the
flat-series fallback, which were domain knowledge living in the frontend.
- `clear_watch_history` maps to Jellyfin's mark-unplayed (recursive over a
container, also zeroes resume). Offline it refuses rather than diverging
state the next sync would undo.
Frontend (DR-102, DR-103, DR-104, DR-107)
- Seasons collapse; only the current one is expanded, and the current
episode is badged and scrolled into view.
- Hero button reads `Resume S2E4` / `Play S1E1` and opens that episode's
focus view, where Play commits (ux-flows §5B.5).
- Seasons are no longer a destination: `/library/<seasonId>` redirects to
`/library/<seriesId>#season-N`, and every inbound link follows.
- The "More Episodes" strip spans the whole series, so a season finale
offers the next premiere instead of dead-ending (§5B.2).
- Clear-history buttons on the series hero and each season header.
Routes (DR-105)
- `/library/tv` and `/library/movies` absorb their all-titles and genres
pages as `?view=` tabs; the four legacy routes redirect. 6 video routes
become 2, and `/library/shows/genres` stops being the odd one out.
Logic extracted to `seriesNavigation.ts`, `episodeStrip.ts` and
`libraryView.ts` so it is unit-tested rather than buried in components.
Spec: docs/specs/series-current-episode-navigation.md
An episode handed off to the audio-only path for background playback is a
MediaType::Audio item, so autoplay's video-only checks stopped
recognising it as an episode: playback simply ended at the episode
boundary instead of continuing to the next one.
- Carry episode identity (item_type, series_id) through the
background-audio handoff so the backend queue item still knows it's an
episode; is_episode_item now trusts item_type over the media_type
heuristic, and the sleep timer's episode counter follows.
- The frontend normally performs the advance by navigating to
/player/<id>, which is unavailable while the WebView is suspended.
advance_to_next_episode_audio_only drives it entirely in the backend:
fetch the next episode, build its audio-only stream URL, and load it
into the native audio player, preserving episode identity so the
following boundary advances too.
- Android's autoplay dispatch routes background-audio episodes to that
backend advance and keeps the countdown path for the foreground.
- get_audio_only_stream_url_for_video joins the MediaRepository trait
(online delegates to the existing builder, offline errors) so the
controller can reach it without a frontend round-trip.
TRACES: UR-040, UR-023 | DR-052 | JA-032
Establish src-tauri/src/domain/ as the single source of truth for the
media model, with all Jellyfin translation isolated in from_jellyfin.rs.
Adds MediaKind enum and neutral duration_ms/image_id fields to MediaItem
as additive, defaulted dual-carry alongside the legacy Jellyfin-named
fields, so nothing breaks while the frontend migrates off them.
- domain/media.rs: canonical MediaKind (closed enum, replaces stringly
item_type), Default = Other so unknown/defaulted items are inert.
- domain/from_jellyfin.rs: total, panic-free item_type -> MediaKind
classification (all audited types + person subroles) and ticks->ms.
- MediaItem gains kind/duration_ms/image_id, populated at both mapping
seams (online to_media_item, offline cached_item_to_media_item) and
the synthesized-album/person sites.
- Regenerated bindings.ts: frontend now HAS the neutral model available.
Phase 1 of docs/specs/frontend-domain-model.md. No frontend behaviour
change yet; wire shape is a superset of before.
Rust 456 tests, frontend 644 tests, check + check:boundary all green.
Replace the flat download list with a Downloaded browse surface that
reuses the online grids/cards/detail pages, filtered to on-device media,
plus a demoted Transfers tab. Add repository browse commands
(getDownloadedLibraries/Items, disk usage) with offline/hybrid
implementations, a downloadedCatalog service, formatBytes helper, and
per-item/device disk-usage labels on cards and grids. Regenerated
bindings.
Also carries the inseparable UR-052 offline-filter hunks in
offline.rs/hybrid.rs.
TRACES: UR-055 | DR-081, DR-082, DR-083, DR-084; UR-056 | DR-085
Hand video playback off to a native audio-only stream when the app is
backgrounded or locked, with no on-device video decode (UR-040). Adds
player_enter/exit_background_audio commands, an audio-only stream URL
for video items across the repository layer, and the frontend handoff
state machine wired into VideoPlayer. Includes accompanying
repository/offline/player refactoring and regenerates the traceability
matrix.
Library screens:
- Add dedicated music, TV, and movie landing pages (hero banner +
horizontal carousels) backed by new music/tv/movies stores.
- Route tvshows libraries to /library/tv; surface rediscover ("haven't
listened to in a while") albums via a new repository method across
online/offline/hybrid repos plus the repository_get_rediscover_albums
command.
- Add an A-Z jump bar for long alphabetically-sorted lists, with grid
index anchors in LibraryGrid/LibraryListView/TrackList.
- Filter the "Podcasts" folder out of music library queries.
Downloads:
- Add a backend queue pump: enqueue_download / enqueue_video_downloads
persist the resolved stream URL + target dir on each row (migration
017), and the pump starts up to max_concurrent and drains the rest
automatically as slots free, instead of the frontend silently dropping
items past the concurrency limit. Album/series/season buttons now
enqueue rather than calling start_download directly.
Other fixes:
- Hybrid search now returns instant cache results and pushes the merged
cache+server union via a request-id-tagged search-event, so superseded
queries can't clobber fresher results.
- URL-encode SearchTerm / genres / item types in online repo requests.
- Android: pause on audio-becoming-noisy (headphone/BT disconnect).
Workstream A — poison-tolerant locking:
- Add utils/lock.rs with MutexSafe/RwLockSafe extension traits that recover a
poisoned std::sync lock instead of panicking, plus unit tests.
- Replace all 153 .lock().unwrap() and 4 .read()/.write().unwrap() production
sites with _safe variants across 14 files, eliminating the player
crash-cascade class. Tokio async mutexes are unchanged.
Workstream B — graceful backend init:
- create_player_backend no longer panics when MPV/ExoPlayer fail to initialize;
it falls back to NullBackend and emits a backend-init-failed event so the UI
can show "playback unavailable" instead of the app crashing. Fatal DB-setup
panics are kept.
Workstream F — doc reconciliation:
- Rewrite software-architecture.md's inaccurate "thin UI / ~800 lines" claims to
reflect reality (~20.5k non-test frontend) and document the events+polling
hybrid plus the new locking/backend-init behavior.
