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.

- Standardize on bun: remove package-lock.json, add packageManager field,
gitignore non-bun lockfiles, fix stray npm install in android:build:clean
- Remove stale build logs and empty dirs (src-tauri/plugins, docs/tickets)
- Move android-dev.sh into scripts/
- Consolidate root docs into docs/ (docker/builder under docs/build/);
move the architecture overview to docs/architecture/README.md
- Extract Requirements Specification from README into docs/requirements.md
and slim README down to a project intro + docs index
- Fix internal references to the moved files
Remove unused imports and a dead test helper, and strengthen tests that
held unused bindings/fields so the values are actually exercised:
- drop unused imports (HttpConfig, MediaType, std::io::Write)
- remove unused TestEventEmitter::clear helper
- replace meaningless size_of asserts with real empty-manager checks
- assert on MockTrack.name in sorting tests
Replace the remaining ~155 untyped invoke() calls across stores, services,
components, and routes with the generated commands.* wrappers from
$lib/api/bindings, so every IPC call is compile-time-checked against the
command signatures.
- Register repository_get_subtitle_url and repository_get_video_download_url
in specta_builder() and the invoke_handler; regenerate bindings.ts.
- Source duplicated wire types (AutoplaySettings, CacheConfig, Session,
ConnectivityStatus, audio/video settings, etc.) from bindings.
- Fix two bugs surfaced by the typed wrappers:
- VideoDownloadButton passed an un-awaited Promise as the stream URL.
- setAutoplaySettings omitted the required userId argument.
- Update unit tests asserting the old invoke(name, args) shape.
- Remove the five param-naming guard tests; the compiler and codegen now
enforce what they checked.
svelte-check: 0 errors. vitest: green. cargo test --lib: green.
- 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.
Casting: restore camelCase serialization on SessionInfo/NowPlayingItem/PlayState
(container rename_all = "camelCase" + per-field PascalCase serde aliases so Jellyfin
PascalCase still deserializes). Bindings and the existing frontend are camelCase
again — casting works with no frontend session changes.
Downloads: migrate DownloadButton.svelte and downloads.ts to the typed
commands.downloadItemAndStart / downloadItem / downloadVideo wrappers (request
objects), matching the bundled backend signatures.
Tooling:
- Enable tauri-specta ErrorHandlingMode::Throw so commands.* return Promise<T>
and throw (drop-in for invoke()).
- Disambiguate specta name collisions: player MediaItem/MediaSource ->
PlayerMediaItem/PlayerMediaSource, auth ServerInfo -> AuthServerInfo.
- Regenerate bindings.ts; svelte-check passes (0 errors).
The tauri-specta `.export(...)` call ran inside run() on every debug app start
and tried to write `../src/lib/api/bindings.ts`, a path that doesn't exist on a
device — `.expect()` panicked at startup, crashing the app instantly on Android.
Bindings are generated by the `export_typescript_bindings` test instead.
- Extract specta_builder() so run() and a #[test] share one command list.
- Add export_typescript_bindings test that writes src/lib/api/bindings.ts.
- Configure the TS exporter bigint behavior to Number (matches existing frontend).
- Commit the generated bindings.ts (typed commands.* wrappers + all DTO types).
- 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.
- Move commands/download.rs to commands/download/mod.rs.
- Extract pin/unpin/is_pinned into download/pinning.rs.
- Extract smart-cache stats/config + album recommendation commands into
download/smart_cache.rs.
- Re-exported via pub use so command names stay at commands::download::*;
invoke_handler unchanged, all tests pass.
- commands/player/timers.rs: sleep-timer + autoplay commands (8).
- commands/player/session.rs: media session get/dismiss commands (2).
- Make create_media_item and get_player_status pub(super) so the submodules can
reuse them. mod.rs shrinks from ~2720 to ~2229 lines; invoke_handler unchanged.
- Move commands/player.rs to commands/player/mod.rs (folder module).
- Extract the 5 self-contained remote-session control commands
(remote_play_on_session/send_command/session_seek/set_volume/toggle_mute)
into commands/player/remote.rs, re-exported via `pub use remote::*` so the
command names remain at commands::player::* and the invoke_handler is unchanged.
No behavior change; establishes the submodule split pattern for the oversized
command file.
Move the pure determine_video_seek_strategy function and its VideoSeekStrategy
enum (plus the 5 seek-strategy unit tests) out of the command layer into
player/seek.rs, where they belong and are testable without the Tauri State
harness. commands/player.rs now imports them from crate::player. No behavior
change.
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.
