- Document all completed optimizations with implementation details
- List remaining low-priority optimizations

-## Optimization Roadmap
+## Optimization Status
 
-Future optimizations are documented in `.claude/optimization-todos.md`. Key areas:
+Most critical optimizations have been implemented. See `.claude/optimization-todos.md` for details.
 
+**Completed:**
+| Area | Implementation |
+|------|----------------|
+| Buffer management | `BufferAccumulator` with auto-trimming |
+| Pre-compiled regex | Module-level patterns with lastIndex resets |
+| Event listener cleanup | `cleanupTrackerListeners()` in session.ts |
+| Event debouncing | 50ms debounce in `inner-loop-tracker.ts` |
+| State update debouncing | 500ms batching in `server.ts` |
+| Regex pre-checks | String.includes() before pattern.test() |
+| Frontend render debouncing | 50-100ms for panels, tabs |
+| CSS containment | `contain` property on terminal, panels, modals |
+| Input batching | 60fps keystroke coalescing |
+| Incremental DOM updates | Session tabs and Ralph todos |
+
+**Remaining:**
 | Priority | Area | Files |
 |----------|------|-------|
-| High | Buffer management | `session.ts`, `respawn-controller.ts` |
-| High | Pre-compiled regex | `session.ts`, `inner-loop-tracker.ts` |
-| Medium | Event listener cleanup | `session.ts`, `respawn-controller.ts` |
