# Step 10 Reliability Round 2

## Coverage

- Reviewed and patched:
  - `iphone/Werkout_ios/BridgeModule+Watch.swift`
  - `iphone/Werkout_ios/BridgeModule+WorkoutActions.swift`
  - `iphone/Werkout_ios/CurrentWorkoutInfo.swift`
  - `iphone/Werkout_watch Watch App/WatchDelegate.swift`
  - `iphone/Werkout_ios/UserStore.swift`
- Validation:
  - `./scripts/smoke/smoke_all.sh`
  - iOS/tvOS analyzer passes

## Fixes

1. Main-thread state safety for watch session callbacks
   - Wrapped `didReceiveMessageData` action handling and `activationDidCompleteWith` state transitions on main.
   - Prevents shared bridge state (`@Published` workout/watch properties + queued message mutations) from being changed off-main.

2. Removed dead closure path that could retain `BridgeModule`
   - Removed unused `CurrentWorkoutInfo.complete` closure and its assignment in `BridgeModule+WorkoutActions.start(workout:)`.
   - Reduces lifecycle risk and removes dead behavior.

3. HealthKit authorization crash hardening on watch launch
   - Replaced force-unwrapped quantity types with guarded optional binding in `WatchDelegate`.
   - Logs and exits cleanly if required HealthKit quantity types are unavailable.

4. Cross-target notification compile stability
   - Updated `UserStore.logout` to post `Notification.Name("CreatedNewWorkout")` directly.
   - Avoids reliance on an iOS-only extension file when `UserStore` is compiled in tvOS target.

## Validation

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