-### 3.10 Player Page Navigation Guard
+### 3.10 Sleep Timer Architecture
+
+**Location**: `src-tauri/src/player/sleep_timer.rs`, `src-tauri/src/player/mod.rs`
+
+**TRACES**: UR-026 | DR-029
+
+The sleep timer supports three modes for stopping playback:
+
+```rust
+#[serde(tag = "kind", rename_all = "camelCase")]
+pub enum SleepTimerMode {
+    Off,
+    Time { end_time: i64 },      // Unix timestamp in milliseconds
+    EndOfTrack,                    // Stop after current track/episode
+    Episodes { remaining: u32 },   // Stop after N more episodes
+}
+```
+
+**Timer Modes:**
+
+| Mode | Trigger | How It Stops |
+|------|---------|-------------|
+| Time | User selects 15/30/45/60 min via roller UI | Background timer thread stops backend when `remaining_seconds == 0`; also checked at track boundaries in `on_playback_ended()` |
+| EndOfTrack | User clicks "End of current track" | Checked in `on_playback_ended()`, returns `AutoplayDecision::Stop` |
+| Episodes | User selects 1-10 episodes | `decrement_episode()` in `on_playback_ended()`, stops when counter reaches 0 |
+
+**Time-Based Timer Flow:**
+
+```mermaid
+sequenceDiagram
+    participant UI as SleepTimerModal
+    participant Store as sleepTimer store
+    participant Rust as PlayerController
+    participant Thread as Timer Thread
+    participant Backend as PlayerBackend
+
+    UI->>Store: setTimeTimer(30)
+    Store->>Rust: invoke("player_set_sleep_timer", {mode})
+    Rust->>Rust: Set SleepTimerMode::Time { end_time }
+    Rust->>UI: Emit SleepTimerChanged event
+
+    loop Every 1 second
+        Thread->>Thread: update_remaining_seconds()
+        Thread->>UI: Emit SleepTimerChanged (countdown)
+        alt remaining_seconds == 0
+            Thread->>Backend: stop()
+            Thread->>UI: Emit SleepTimerChanged (Off)
+        end
+    end
+```
+
+**Frontend Components:**
+
+- **ScrollPicker** (`src/lib/components/common/ScrollPicker.svelte`): Reusable scroll-wheel picker using CSS `scroll-snap-type: y mandatory`. Configurable items, visible count, and item height. Used by SleepTimerModal for time selection.
+- **SleepTimerModal** (`src/lib/components/player/SleepTimerModal.svelte`): Modal with three sections — time picker (roller), end of track button, episode counter. Time section uses ScrollPicker with 15/30/45/60 min options. Accepts optional `mediaType` prop to override queue-based detection (used by VideoPlayer since video playback clears the audio queue).
+- **SleepTimerIndicator** (`src/lib/components/player/SleepTimerIndicator.svelte`): Compact indicator showing active timer status with countdown.
+- **Sleep buttons**: Clock icon buttons on AudioPlayer header, Controls bar, MiniPlayer, and VideoPlayer control bar. Shows clock icon when inactive, SleepTimerIndicator when active.
+
+**Key Design Decisions:**
+
+1. **All logic in Rust**: Frontend only displays state and invokes commands
+2. **Background timer thread**: Handles time-based countdown independently of track boundaries
+3. **Dual stop mechanism for Time mode**: Timer thread stops mid-track; `on_playback_ended()` catches edge case at track boundary
+4. **Event-driven UI updates**: Timer thread emits `SleepTimerChanged` every second for countdown display
+
+### 3.11 Auto-Play Episode Limit
+
+**Location**: `src-tauri/src/player/mod.rs`, `src-tauri/src/player/autoplay.rs`, `src-tauri/src/settings.rs`
+
+**TRACES**: UR-023 | DR-049
+
+Limits how many episodes auto-play consecutively before requiring manual intervention.
+
+**Settings:**
+
+```rust
+// In AutoplaySettings (runtime, in PlayerController)
+pub struct AutoplaySettings {
+    pub enabled: bool,
+    pub countdown_seconds: u32,
+    pub max_episodes: u32,  // 0 = unlimited
+}
+
+// In VideoSettings (persisted, settings page)
+pub struct VideoSettings {
+    pub auto_play_next_episode: bool,
+    pub auto_play_countdown_seconds: u32,
+    pub auto_play_max_episodes: u32,  // 0 = unlimited
+}
+```
+
+**Session-Based Counter:**
+
+The `autoplay_episode_count` field in `PlayerController` tracks consecutive auto-played episodes:
+
+- **Incremented**: In `on_playback_ended()` when auto-playing next episode
+- **Reset**: On any manual user action (`play_item()`, `play_queue()`, `next()`, `previous()`)
+- **Limit check**: When `max_episodes > 0` and `count >= max_episodes`, the popup shows with `auto_advance: false` — user must manually click "Play Now" to continue
+
+```mermaid
+flowchart TB
+    PlaybackEnded["on_playback_ended()"] --> CheckEpisode{"Is video<br/>episode?"}
+    CheckEpisode -->|"No"| AudioFlow["Audio queue logic"]
+    CheckEpisode -->|"Yes"| FetchNext["Fetch next episode"]
+    FetchNext --> IncrementCount["increment_autoplay_count()"]
+    IncrementCount --> CheckLimit{"max_episodes > 0<br/>AND count >= max?"}
+    CheckLimit -->|"No"| ShowPopup["ShowNextEpisodePopup<br/>auto_advance: true"]
+    CheckLimit -->|"Yes"| ShowPopupManual["ShowNextEpisodePopup<br/>auto_advance: false"]
+    ShowPopupManual --> UserClick["User clicks 'Play Now'"]
+    UserClick --> PlayItem["play_item() → resets counter"]
+```
+
+**Settings Sync:**
+
+`VideoSettings` (settings page) and `AutoplaySettings` (PlayerController runtime) are synced via `player_set_video_settings`, which updates both the `VideoSettingsWrapper` state and calls `controller.set_autoplay_settings()`.
+
+**Database**: Migration 016 adds `autoplay_max_episodes INTEGER DEFAULT 0` to `user_player_settings`.
+
+**Settings UI**: Button grid with options: Unlimited, 1, 2, 3, 5, 10 episodes. Visible only when auto-play is enabled.
