Rust: PlayerMediaItem and MergedMediaItem gain image_id (dual-carry),
populated from primary_image_tag at every construction/conversion site.
Regenerated bindings.
Frontend: all catalog + player + merged readers now use imageId. The
NowPlayingItem->MediaItem bridge (player.ts) properly maps the remote
session's Jellyfin fields (Type, runTimeTicks, primaryImageTag) onto the
neutral kind/durationMs/imageId. Types that are genuinely out of scope
(Person, NowPlayingItem, PlayItemRequest) keep primaryImageTag.
Rust 456, frontend 644, check clean.
The catalog surface now speaks milliseconds, the app's neutral time unit.
Ticks no longer reach library/home components.
Rust:
- UserData gains playback_position_ms (dual-carry), populated from ticks
at the offline mapping seam via domain::ticks_to_ms.
Frontend:
- formatDuration(duration.ts) and the two local copies now take ms, not
ticks; all callers pass item.durationMs.
- Progress bars (EpisodeRow, EpisodeFocusView, MediaCard, LibraryListView)
compute playbackPositionMs / durationMs — unit-consistent, no tick math.
- PlaylistDetailView totalDuration sums durationMs.
- duration.test.ts + TrackList.test.ts fixtures updated to ms.
Deferred: player/session/reporting tick math (Queue, SessionCard,
RemoteControls, playbackReporting, playerEvents) — those cross the
storage/Jellyfin command boundary in ticks and need command-signature
changes (phase 3b). Display {item.type} badge -> kind label (phase 4).
Rust 456, frontend 644, check + check:boundary clean.
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.
- music landing: diverse per-genre album sliders (online counts /
offline wide-probe fallback) and home-screen library shortcuts
- add ArtistLinks component and shared navigation/genreDiversity utils
- player/playback-mode refinements across Rust and frontend
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).
The offline/online switch was janky because two independent systems decided
"online" and never communicated:
- ConnectivityMonitor owned is_server_reachable (drove the UI banner) but
learned reachability only from a standalone /System/Info/Public ping loop
and from auth/login calls.
- HybridRepository served all real data by racing cache-vs-server but never
read or wrote reachability.
So the banner reflected a side-channel poller, not the system the user actually
experienced: a successful ping could read "online" while authenticated data
calls 401'd or timed out, and three different timeout regimes (5s ping / 30s
data / 100ms cache race) flapped against each other.
Unify into a single source of truth:
- Extract a cheap, cloneable ConnectivityReporter that owns all reachability
transitions and event emission.
- OnlineRepository reports the outcome of every server request to the reporter,
classified via RepoError: Ok/Authentication/NotFound/Server => reachable
(the server answered), Network => offline candidate, Database/Offline =>
ignored (not a server signal).
- Time-window debounce (OFFLINE_CONFIRM_WINDOW = 5s): flip offline only after
sustained network failure; recover instantly on the first success.
- Demote the ping loop to an offline-only recovery probe (no online polling;
real traffic is the signal when online).
- Frontend: navigator.onLine is now advisory (triggers a recheck instead of
forcing offline); removed the dead markReachable/markUnreachable store methods.
Docs updated (README, 07-connectivity, 03-data-flow, 02-svelte-frontend) to
describe the new model and fix pre-existing drift (HTTP client is 30s timeout +
5s ping, not the documented 10s/base_url).
Tests: 12 connectivity tests (debounce, instant recovery, RepoError
classification through report_outcome). Full suite: 398 Rust + 384 frontend
passing, svelte-check clean.

- online.rs: on Linux, advertise only WebView-decodable codecs (h264 video;
aac/mp3/opus/vorbis/flac audio) in PlaybackInfo so Jellyfin transcodes
HEVC/AV1/VP9/etc. to h264 HLS for the WebKitGTK <video> element.
- player: on Linux, don't load video into MPV (no embedded window — it would
start a redundant decode the frontend immediately stops). Add
PlayerController::set_current_item to keep queue/UI/remote-transfer state in
sync without loading the item into the playback backend.
- Add #[specta::specta] to all 201 #[tauri::command] functions.
- Derive specta::Type on all IPC DTOs (repository/types, settings, player/storage/
download command DTOs, player enums, jellyfin SessionInfo/NowPlayingItem/PlayState,
ThumbnailCacheStats, DownloadInfo, CacheConfig, etc.).
- Replace tauri::generate_handler! with a tauri_specta::Builder + collect_commands!
in lib.rs (exports bindings.ts in debug builds).
Two contract changes required by specta constraints (frontend migration follows):
- specta caps command arity at 10 args: download_item_and_start / download_item /
download_video now take a single request struct (params bundled, body unchanged
via destructuring).
- specta can't parse split serde rename_all: SessionInfo/NowPlayingItem/PlayState
switched to rename_all = "PascalCase" (Jellyfin deserialization preserved; these
now serialize PascalCase to the frontend).
cargo check --lib is clean (0 errors). Frontend migration to bindings.ts is the next step.
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.
