- Handle loading, unauthenticated, permission-denied, and unavailable states truthfully in metric-card-lean (Peak Lean Angle KPI) rather than falling back to '--' and 'No IMU roll data'
- Reset metrics state to null on auth change and in onStatusChange loading/error branches to prevent stale metrics retention
- Add race condition guard in AppCloudData.loadData to discard in-flight results if firebaseAuth.currentUser changed during asynchronous fetch
- Prioritize Disconnected and Connecting states over sample example messages in real club mode in founder-chat.tsx
- Clear chat messages on channel switch in founder-chat.tsx to eliminate cross-channel message bleed, and fix invalid py-0.2 Tailwind classes to py-0.5
- Add regression tests in account-metrics-truthfulness.test.tsx and founder-routes-chat.test.tsx
