## Risk Register

| Risk | Mitigation |
| ---- | ---------- |
| Cursor drift | Do not replace source text |
| Slow typing | Render only dirty lines |
| Unstable scrolling | Preserve native scroll origin |

## Definition of Done

- [x] Unit tests cover new render plan cases.
- [x] Sample documents cover real writing shapes.
- [ ] Visual review in the app.
- [ ] 5 MB benchmark remains acceptable.
