 8. **WebUI Render Debouncing**: Added debouncing to `renderInnerStatePanel` (50ms), `renderTaskPanel` (100ms), `renderScreenSessions` (100ms)
 9. **CSS Containment**: Added `contain` property to terminal container, session tabs, ralph panel, task panel, and modal content for paint isolation
 10. **GPU-Accelerated Animations**: Added `will-change` for animated elements, use transform-based transitions
+11. **Input Batching**: Batch rapid keystrokes at 60fps, immediate flush for control chars
+12. **Incremental DOM Updates**: Reuse existing DOM elements in Ralph todo list, ~80% fewer DOM ops

 ### High Priority
 
-| Optimization | File | Description | Expected Impact |
-|-------------|------|-------------|-----------------|
-| Virtual scrolling for todo lists | `app.js` | Render only visible todos for long lists | 10x improvement for 100+ todos |
-| Incremental DOM updates | `app.js` | Use DOM diffing instead of innerHTML | Reduces reflows by 50% |
-| Web Worker for JSON parsing | `app.js` | Offload SSE message parsing to worker | Smoother UI during high throughput |
-| Request coalescing | `app.js` | Batch rapid API calls (resize, input) | Fewer network requests |
