+  JellyTau
+</h1>
 
 A cross-platform Jellyfin client built with Tauri, SvelteKit, and TypeScript.
 
-## Recommended IDE Setup
+Business logic lives in a Rust backend; a UI-rich Svelte frontend handles
+presentation and talks to it over Tauri's IPC. Targets Linux (libmpv) and
+Android (ExoPlayer).
 
-[VS Code](https://code.visualstudio.com/) + [Svelte](https://marketplace.visualstudio.com/items?itemName=svelte.svelte-vscode) + [Tauri](https://marketplace.visualstudio.com/items?itemName=tauri-apps.tauri-vscode) + [rust-analyzer](https://marketplace.visualstudio.com/items?itemName=rust-lang.rust-analyzer).
+## Getting Started
 
----
+This project uses [bun](https://bun.sh) as its package manager.

-### Linux Keyring Integration Workaround
+## License
 
-**Issue**: The `keyring-rs` crate (v3.x) has issues with retrieving credentials from the Linux Secret Service API, despite successfully saving them.
+MIT
-
-**Symptoms**:
-- Credentials are saved to the system keyring successfully (verified with `secret-tool search`)
-- Retrieval via the `keyring-rs` library fails with `NoEntry` error
-- Session restoration fails on app restart even though credentials exist
-
-**Root Cause**:
-The `keyring-rs` library's Linux backend doesn't correctly retrieve entries from the Secret Service that it previously stored. This appears to be a bug in how the library interfaces with the Secret Service D-Bus API.
-
-**Current Workaround**:
-We bypass the `keyring-rs` library on Linux and use direct system calls to `secret-tool`:
-- **Save**: `secret-tool store --label <label> service <service> username <username>`
-- **Retrieve**: `secret-tool lookup service <service> username <username>`
-- **Delete**: `secret-tool clear service <service> username <username>`
-
-**Implementation**:
-See [src-tauri/src/credentials.rs](src-tauri/src/credentials.rs):
-- Lines 165-209: `save_to_keyring()` - Uses `secret-tool store` on Linux
-- Lines 214-248: `get_from_keyring()` - Uses `secret-tool lookup` on Linux
-- Lines 254-286: `delete_from_keyring()` - Uses `secret-tool clear` on Linux
-
-**Future Fix**:
-- Monitor `keyring-rs` for bug fixes in future versions
-- Consider alternative secure storage libraries
-- Test if newer versions of `keyring-rs` (v4.x+) resolve the issue
-- Once fixed, remove the Linux-specific workaround and use the cross-platform `keyring-rs` API
-
-**Impact**:
-- Low - The workaround is functionally equivalent to proper keyring integration
-- Credentials are stored securely in the system keyring
-- Session restoration works correctly
-- Only affects Linux; macOS and Windows use the standard `keyring-rs` implementation
-
-**Dependencies**:
-- Requires `secret-tool` to be installed on Linux systems (part of `libsecret-tools` package)
-- Already available on most Linux distributions by default

-### Platform Playback Backend Parity (Linux vs Android)
-
-**Issue**: The Linux (MPV) and Android (ExoPlayer) playback backends have diverged in feature implementation and architecture patterns.
-
-**Symptoms**:
-- Audio settings (crossfade, gapless playback, volume normalization) work on Linux but not on Android
-- Position update frequency differs between platforms (Linux: 250ms polling, Android: on-demand callbacks)
-- Thread safety models differ (Linux: `Arc<Mutex<>>`, Android: global `OnceLock` statics)
-
-**Root Cause**:
-The `PlayerBackend` trait defines optional audio settings methods with default empty implementations. The Linux `MpvBackend` overrides these with full MPV property commands, but `ExoPlayerBackend` uses the defaults.
-
-**Affected Files**:
-- [src-tauri/src/player/backend.rs:95-103](src-tauri/src/player/backend.rs) - Trait with default empty implementations
-- [src-tauri/src/player/mpv/mod.rs](src-tauri/src/player/mpv/mod.rs) - Full audio settings support
-- [src-tauri/src/player/android/mod.rs](src-tauri/src/player/android/mod.rs) - Missing audio settings implementation
-
-**Feature Parity Matrix**:
-
-| Feature | Linux (MPV) | Android (ExoPlayer) | Status |
-|---------|-------------|---------------------|--------|
-| Basic playback | ✅ | ✅ | Parity |
-| Volume control | ✅ | ✅ | Parity |
-| Seek | ✅ | ✅ | Parity |
-| Crossfade | ✅ | ❌ | Gap |
-| Gapless playback | ✅ | ❌ | Gap |
-| Volume normalization | ✅ | ❌ | Gap |
-| Position updates | 250ms | On-demand | Inconsistent |
-
-**Future Fix**:
-1. Implement `set_audio_settings()` in `ExoPlayerBackend`
-2. Add Kotlin-side ExoPlayer configuration for crossfade (using `ConcatenatingMediaSource` or `DefaultMediaSourceFactory`)
-3. Implement gapless via ExoPlayer's built-in gapless support
-4. Add volume normalization via ExoPlayer's `LoudnessEnhancer` or audio processor
-5. Standardize position update frequency across platforms
-
-**Impact**:
-- Medium - Android users lack audio enhancement features advertised in requirements
-- User experience differs between platforms
-- UR-031 (Crossfade), UR-032 (Gapless), UR-033 (Normalization) only work on Linux
-
-**Traces To**: IR-004, UR-031, UR-032, UR-033, DR-034, DR-035, DR-036

-### Frontend Playback Code Duplication
-
-**Issue**: Playback control handlers and state derivations are duplicated between `AudioPlayer.svelte` and `MiniPlayer.svelte`.
-
-**Symptoms**:
-- Identical try-catch wrapped handler functions in both components (~44 lines duplicated)
-- Same `$derived` state merging logic for local/remote playback in both components
-- Position conversion (ticks ↔ seconds) scattered across multiple files
-
-**Affected Files**:
-- [src/lib/components/player/AudioPlayer.svelte:69-140](src/lib/components/player/AudioPlayer.svelte) - Duplicate handlers
-- [src/lib/components/player/MiniPlayer.svelte:74-122](src/lib/components/player/MiniPlayer.svelte) - Duplicate handlers
-- [src/lib/services/playbackControl.ts:88](src/lib/services/playbackControl.ts) - Position conversion
-- [src/lib/stores/playbackMode.ts](src/lib/stores/playbackMode.ts) - Position conversion
-- [src/lib/services/playbackReporting.ts](src/lib/services/playbackReporting.ts) - Position conversion
-
-**Duplicated Code**:
-```typescript
-// These handlers are identical in both AudioPlayer and MiniPlayer:
-handlePlayPause(), handleNext(), handlePrevious(),
-handleToggleShuffle(), handleCycleRepeat(), handleVolumeChange()
-
-// These derived states use identical logic:
-displayMedia, displayIsPlaying, displayPosition, displayDuration
-```
-
-**Future Fix**:
-1. Create `src/lib/utils/playbackUnits.ts`:
-   ```typescript
-   export const TICKS_PER_SECOND = 10_000_000;
-   export const secondsToTicks = (s: number) => Math.floor(s * TICKS_PER_SECOND);
-   export const ticksToSeconds = (t: number) => t / TICKS_PER_SECOND;
-   ```
-
-2. Create `src/lib/composables/useMergedPlaybackState.svelte.ts`:
-   - Export `displayMedia`, `displayIsPlaying`, `displayPosition`, `displayDuration`
-   - Single source of truth for merged local/remote state
-
-3. Simplify handler wrappers using a utility:
-   ```typescript
-   export const withErrorHandler = (fn: () => Promise<void>, context: string) =>
-     async () => { try { await fn(); } catch (e) { console.error(`${context}:`, e); } };
-   ```
-
-**Impact**:
-- Low - Code works correctly but violates DRY principle
-- Maintenance burden when logic needs to change
-- Risk of handlers diverging over time
-
-**Traces To**: DR-009

+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

+
+**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.

-The connectivity monitor tracks server reachability with adaptive polling:
+The connectivity monitor is the **single source of truth** for server reachability. Its primary signal is the outcome of *real repository traffic* — every server request the user actually makes. A standalone `/System/Info/Public` probe is kept only as an offline recovery detector.
+
+### Source of truth: repository traffic
+
+`OnlineRepository` reports the result of each server request to the monitor, classified via `RepoError`:
+
+| Repository outcome | Meaning | Effect on reachability |
+|--------------------|---------|------------------------|
+| `Ok(_)` | Server answered successfully | Mark **reachable** (instant recovery) |
+| `Err(Authentication)` | Server answered with 401/403 | Mark **reachable** (server is up; request was rejected) |
+| `Err(NotFound)` | Server answered with 404 | Mark **reachable** (server is up) |
+| `Err(Server)` | Server answered with 5xx / bad body | Mark **reachable** (server is up) |
+| `Err(Network)` | Connection failure / timeout / DNS | **Candidate for offline** (see debounce) |
+| `Err(Database)` | Local cache error only | No effect (not a server signal) |
+
+This classification fixes the previous bug where a successful `/System/Info/Public` ping reported "online" even while the user's authenticated data calls were failing — and vice versa.
+
+### Time-window debounce (offline) + instant recovery (online)
+
+To stop the banner from flapping on a single dropped request, the transition to **offline** is debounced over a time window:
+
+- On the **first** `Network` failure, the monitor records `first_failure_at`.
+- It flips `is_server_reachable = false` only once `Network` failures have persisted continuously for `OFFLINE_CONFIRM_WINDOW` (5s) with no intervening success.
+- **Any** success (or server-answered error) clears `first_failure_at` and immediately marks reachable.
+
+Recovery is therefore instant and asymmetric: one good response brings the app back online, but a brief blip never trips the banner.

 - **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)).

The standalone `/System/Info/Public` probe runs *only while offline*, as a recovery detector for idle sessions.
 - **Poison-tolerant locking**: Shared `std::sync` state is accessed via the `MutexSafe`/`RwLockSafe` helpers in `utils/lock.rs`, which recover a poisoned lock instead of cascading a panic across the player.
 - **Graceful backend init**: If a native player backend (MPV/ExoPlayer) fails to initialize, the app falls back to a no-op backend and emits a `backend-init-failed` event rather than crashing.

+## 5. Technical Debt
+
+### Linux Keyring Integration Workaround
+
+**Issue**: The `keyring-rs` crate (v3.x) has issues with retrieving credentials from the Linux Secret Service API, despite successfully saving them.
+
+**Symptoms**:
+- Credentials are saved to the system keyring successfully (verified with `secret-tool search`)
+- Retrieval via the `keyring-rs` library fails with `NoEntry` error
+- Session restoration fails on app restart even though credentials exist
+
+**Root Cause**:
+The `keyring-rs` library's Linux backend doesn't correctly retrieve entries from the Secret Service that it previously stored. This appears to be a bug in how the library interfaces with the Secret Service D-Bus API.
+
+**Current Workaround**:
+We bypass the `keyring-rs` library on Linux and use direct system calls to `secret-tool`:
+- **Save**: `secret-tool store --label <label> service <service> username <username>`
+- **Retrieve**: `secret-tool lookup service <service> username <username>`
+- **Delete**: `secret-tool clear service <service> username <username>`
+
+**Implementation**:
+See [src-tauri/src/credentials.rs](../src-tauri/src/credentials.rs) for the
+Linux-specific `secret-tool` save/get/delete paths.
+
+**Future Fix**:
+- Monitor `keyring-rs` for bug fixes in future versions
+- Consider alternative secure storage libraries
+- Test if newer versions of `keyring-rs` (v4.x+) resolve the issue
+- Once fixed, remove the Linux-specific workaround and use the cross-platform `keyring-rs` API
+
+**Impact**:
+- Low - The workaround is functionally equivalent to proper keyring integration
+- Credentials are stored securely in the system keyring
+- Session restoration works correctly
+- Only affects Linux; macOS and Windows use the standard `keyring-rs` implementation
+
+**Dependencies**:
+- Requires `secret-tool` to be installed on Linux systems (part of `libsecret-tools` package)
+- Already available on most Linux distributions by default

+### Platform Playback Backend Parity (Linux vs Android)
+
+**Issue**: The Linux (MPV) and Android (ExoPlayer) playback backends have diverged in feature implementation and architecture patterns.
+
+**Symptoms**:
+- Audio settings (crossfade, gapless playback, volume normalization) work on Linux but not on Android
+- Position update frequency differs between platforms (Linux: 250ms polling, Android: on-demand callbacks)
+- Thread safety models differ (Linux: `Arc<Mutex<>>`, Android: global `OnceLock` statics)
+
+**Root Cause**:
+The `PlayerBackend` trait defines optional audio settings methods with default empty implementations. The Linux `MpvBackend` overrides these with full MPV property commands, but `ExoPlayerBackend` uses the defaults.
+
+**Affected Files**:
+- [src-tauri/src/player/backend.rs](../src-tauri/src/player/backend.rs) - Trait with default empty implementations
+- [src-tauri/src/player/mpv_backend.rs](../src-tauri/src/player/mpv_backend.rs) - Full audio settings support
+- [src-tauri/src/player/android/mod.rs](../src-tauri/src/player/android/mod.rs) - Missing audio settings implementation
+
+**Feature Parity Matrix**:
+
+| Feature | Linux (MPV) | Android (ExoPlayer) | Status |
+|---------|-------------|---------------------|--------|
+| Basic playback | ✅ | ✅ | Parity |
+| Volume control | ✅ | ✅ | Parity |
+| Seek | ✅ | ✅ | Parity |
+| Crossfade | ✅ | ❌ | Gap |
+| Gapless playback | ✅ | ❌ | Gap |
+| Volume normalization | ✅ | ❌ | Gap |
+| Position updates | 250ms | On-demand | Inconsistent |
+
+**Future Fix**:
+1. Implement `set_audio_settings()` in `ExoPlayerBackend`
+2. Add Kotlin-side ExoPlayer configuration for crossfade (using `ConcatenatingMediaSource` or `DefaultMediaSourceFactory`)
+3. Implement gapless via ExoPlayer's built-in gapless support
+4. Add volume normalization via ExoPlayer's `LoudnessEnhancer` or audio processor
+5. Standardize position update frequency across platforms
+
+**Impact**:
+- Medium - Android users lack audio enhancement features advertised in requirements
+- User experience differs between platforms
+- UR-031 (Crossfade), UR-032 (Gapless), UR-033 (Normalization) only work on Linux
+
+**Traces To**: IR-004, UR-031, UR-032, UR-033, DR-034, DR-035, DR-036
+
+---
+
+### Frontend Playback Code Duplication
+
+**Issue**: Playback control handlers and state derivations are duplicated between `AudioPlayer.svelte` and `MiniPlayer.svelte`.
+
+**Symptoms**:
+- Identical try-catch wrapped handler functions in both components (~44 lines duplicated)
+- Same `$derived` state merging logic for local/remote playback in both components
+- Position conversion (ticks ↔ seconds) scattered across multiple files
+
+**Affected Files**:
+- [src/lib/components/player/AudioPlayer.svelte](../src/lib/components/player/AudioPlayer.svelte) - Duplicate handlers
+- [src/lib/components/player/MiniPlayer.svelte](../src/lib/components/player/MiniPlayer.svelte) - Duplicate handlers
+- [src/lib/services/playbackControl.ts](../src/lib/services/playbackControl.ts) - Position conversion
+- [src/lib/stores/playbackMode.ts](../src/lib/stores/playbackMode.ts) - Position conversion
+- [src/lib/services/playbackReporting.ts](../src/lib/services/playbackReporting.ts) - Position conversion
+
+**Duplicated Code**:
+```typescript
+// These handlers are identical in both AudioPlayer and MiniPlayer:
+handlePlayPause(), handleNext(), handlePrevious(),
+handleToggleShuffle(), handleCycleRepeat(), handleVolumeChange()
+
+// These derived states use identical logic:
+displayMedia, displayIsPlaying, displayPosition, displayDuration
+```
+
+**Future Fix**:
+1. Create `src/lib/utils/playbackUnits.ts`:
+   ```typescript
+   export const TICKS_PER_SECOND = 10_000_000;
+   export const secondsToTicks = (s: number) => Math.floor(s * TICKS_PER_SECOND);
+   export const ticksToSeconds = (t: number) => t / TICKS_PER_SECOND;
+   ```
+
+2. Create `src/lib/composables/useMergedPlaybackState.svelte.ts`:
+   - Export `displayMedia`, `displayIsPlaying`, `displayPosition`, `displayDuration`
+   - Single source of truth for merged local/remote state
+
+3. Simplify handler wrappers using a utility:
+   ```typescript
+   export const withErrorHandler = (fn: () => Promise<void>, context: string) =>
+     async () => { try { await fn(); } catch (e) { console.error(`${context}:`, e); } };
+   ```
+
+**Impact**:
+- Low - Code works correctly but violates DRY principle
+- Maintenance burden when logic needs to change
+- Risk of handlers diverging over time
+
+**Traces To**: DR-009
