 **Important**: The command is `player_get_queue` (returns `QueueStatus` with `hasNext`/`hasPrevious`). There is no `player_get_queue_status` command.

+**Location**: `src/lib/player/html5Adapter.ts`, `src/lib/player/index.ts`, report commands in
+`src-tauri/src/commands/player/timers.rs`
+
+Video on desktop (Linux WebKitGTK) — and, per current interim behavior, Android — is rendered by an
+HTML5 `<video>`/HLS element **inside the webview**. libmpv is initialized audio-only (`vo=null`,
+`video=false`), so the native backend cannot render or observe this element. The `<video>` is therefore
+the real player, living outside Rust's reach.
+
+To keep the `PlayerController` the single source of truth (matching the audio path), the HTML5 element
+is treated as **a dumb output device that reports back into Rust**, rather than an independent state
+authority:

+
+    Video -->|DOM events| Adapter --> Cmds --> Controller --> Emitter --> Events --> Store
+```
+
+**Key points:**
+- The adapter re-emits the *same* `PlayerStatusEvent`s (`StateChanged`, `PositionUpdate`, `MediaLoaded`)
+  the native backends emit, so `playerEvents.ts` needs **no** HTML5-specific branch — HTML5 is just
+  another event source feeding the existing pipeline.
+- Position reports are throttled (~250ms) to match the MPV cadence and avoid flooding IPC from the
+  60fps RAF loop.
+- **Boundary rule**: UI components never touch the report commands or `videoElement` state directly.
+  Playback *control* goes through the unified facade `src/lib/player/index.ts` (`playerController`);
+  HTML5 *state reporting* goes through `html5Adapter.ts`. This restores the documented invariant
+  ("frontend only displays state and invokes commands") for the video path.

@@ -13,6 +13,7 @@ JellyTau uses a client-server architecture: business logic lives in a comprehens
 - **Business Logic in Rust**: Core logic — playback, repository, sync, downloads, connectivity — lives in Rust for performance, reliability, and type safety.
 - **Presentation in Svelte**: The frontend (~20.5k non-test lines) owns UI, layout, navigation, and interaction state and invokes Rust commands. It is intentionally UI-heavy, **not** a thin wrapper. Largest pieces: components + routes (~14.6k lines), stores (~3.4k), api/services/utils (~2.4k); `VideoPlayer.svelte` alone is ~1.6k lines.
 - **Events + Polling hybrid**: Rust emits events the frontend listens to, and the UI also polls status on short intervals in a few hot spots (e.g. queue status in `library/+layout.svelte`, playback progress in `VideoPlayer.svelte`).
+- **Unified player boundary**: UI components control playback only through the frontend facade `src/lib/player/index.ts` (`playerController`), never by calling `commands.player*` directly. Webview-rendered HTML5 video reports its state back into Rust via `src/lib/player/html5Adapter.ts` and the `player_report_*` commands, so the `PlayerController` stays the single source of truth in both native (MPV/ExoPlayer) and HTML5 modes (see [05-platform-backends.md](05-platform-backends.md)).
 - **Handle-Based Resources**: UUID handles for stateful Rust objects.
 - **Cache-First**: Parallel queries with intelligent fallback.
 - **Single source of truth for reachability**: Server reachability is derived from the outcome of *real repository traffic*, not a side-channel poller. The `OnlineRepository` reports each server result to the `ConnectivityMonitor` (classified via `RepoError`), which applies a time-window debounce before declaring the server offline and recovers instantly on the first success. The standalone `/System/Info/Public` probe runs *only while offline*, as a recovery detector for idle sessions.

+//! Tauri commands for the offline "browse & queue" feature.
+//!
+//! Two backend pieces support browsing the full server catalog while offline
+//! and queueing downloads that fire on reconnect:
+//!
+//! - [`sync_full_catalog`] walks every library while online and persists all
+//!   items to the offline cache so the whole catalog is browsable (greyed out)
+//!   offline. It reuses [`HybridRepository::cache_items_from_server`], which in
+//!   turn reuses `OfflineRepository::save_to_cache` (sets `synced_at`, which is
+//!   what `get_items` branch 3 serves offline).
+//! - [`resume_queued_downloads`] resolves and pumps the `pending` download rows
+//!   that were queued offline (they have `stream_url IS NULL`), mirroring the
+//!   heal-and-pump pattern in `player_preload_upcoming`.
