### AI Sessions MCP Report: React Native Authentication Flow (Last 30 Days)

#### Session Overview
- **Total Sessions Found:** 12
- **Time Range:** May 1-30, 2024
- **Primary Tools Used:** Claude Code (7 sessions), OpenAI Codex (5 sessions)
- **Topics Covered:** JWT token handling, Firebase integration, error boundary implementation

#### Key Insights
1. **JWT Token Refresh Logic:** 6 sessions focused on optimizing token refresh timings to avoid 401 errors. The most stable implementation used a 15-minute buffer before expiration.
2. **Firebase Auth State Persistence:** Sessions #4 and #8 revealed a race condition where `onAuthStateChanged` fired before the app was fully initialized. The solution was to wrap the auth listener in a `useEffect` with a dependency array.
3. **Error Boundaries:** Sessions #3 and #11 documented a common crash when the auth token expired mid-navigation. The fix involved adding a global error boundary with a retry mechanism.

#### Reusable Code
```javascript
// Token refresh utility (from Session #7)
const refreshToken = async (expiredToken) => {
  try {
    const response = await fetch('/api/refresh-token', {
      method: 'POST',
      headers: { 'Authorization': `Bearer ${expiredToken}` }
    });
    const { newToken } = await response.json();
    return newToken;
  } catch (error) {
    console.error('Token refresh failed:', error);
    throw error;
  }
};

// Firebase auth setup with race condition fix (from Session #4)
useEffect(() => {
  const unsubscribe = auth.onAuthStateChanged(async (user) => {
    if (user) {
      await initializeApp(user); // Wait for app to be ready
    }
  });
  return () => unsubscribe();
}, []);
```

#### Action Items
1. **Document the JWT refresh logic** in the team’s internal wiki (from Session #7).
2. **Implement the race condition fix** in the staging branch by EOD (from Session #4).
3. **Add error boundary tests** to the CI pipeline (from Session #11).
4. **Schedule a team retro** to review all 12 sessions and identify patterns for the next sprint.
