## Session Log (2026-01-21)
### Completed This Session:
1. **Regex lastIndex Fix** (#2): Moved lastIndex resets to BEFORE .test() calls in inner-loop-tracker.ts
2. **Event Listener Cleanup** (#4): Added `cleanupTrackerListeners()` in session.ts to properly remove TaskTracker and InnerLoopTracker listeners
3. **Event Debouncing** (#4): Added 50ms debouncing for todoUpdate/loopUpdate events in InnerLoopTracker
4. **Regex Pre-checks** (#6): Added fast pre-checks (string.includes) before expensive regex execution
5. **Promise Race Condition Fix**: Added `_promptResolved` flag in session.ts to prevent double resolution
6. **State Update Debouncing** (#10): Added `broadcastSessionStateDebounced()` in server.ts batching at 500ms intervals
7. **withTimeout Utility**: Added exported utility for async operation protection with configurable timeouts
