# Step 9 Memory/Lifecycle Round 1

## Coverage

- Audited lifecycle cleanup and resource teardown in:
  - `iphone/Werkout_ios/subview/PlayerUIView.swift`
  - `iphone/Werkout_ios/Views/WorkoutDetail/WorkoutDetailView.swift`
  - `iphone/Werkout_ios/Views/WorkoutDetail/ExerciseListView.swift`
  - `iphone/Werkout_ios/Views/ExternalWorkoutDetailView.swift`
  - `iphone/Werkout_ios/subview/AllExerciseView.swift`
  - `iphone/Werkout_ios/Views/CreateWorkout/CreateExerciseActionsView.swift`
  - `iphone/Werkout_ios/AudioEngine.swift`
  - `WekoutThotViewer/WekoutThotViewer/ContentView.swift`
- Validation:
  - `./scripts/smoke/smoke_all.sh`

## Fixes

1. Player view teardown safety
   - `PlayerView` now pauses previous players when swapping and performs explicit teardown in `dismantleUIView`.

2. Workout detail closure retention risk
   - Clears `BridgeModule.shared.completedWorkout` on `WorkoutDetailView` disappear.

3. Player pause on dismiss across views
   - Added `onDisappear` player pause in workout detail exercise list, create-exercise preview, all-exercise preview, external display, and tvOS content view.

4. External display player reuse
   - Added URL tracking + replay path to avoid reallocating AVPlayer when URL is unchanged.

5. Audio playback resource churn
   - Stops existing players before replacement and logs failures via `RuntimeReporter` instead of `print`.

## Validation

- Smoke suite passed:
  - token scan
  - SharedCore tests
  - iOS/watchOS/tvOS builds
