### 2025-12-05: Data Safety Mitigations Added
Added safety mitigations for Automerge format conversion (commit f8092d8 on feature/google-export):
**Pre-conversion backups:**
- Before any format migration, raw document backed up to R2
- Location: `pre-conversion-backups/{roomId}/{timestamp}_{formatType}.json`
**Conversion threshold guards:**
- 10% loss threshold: Conversion aborts if too many records would be lost
- 5% shape loss warning: Emits warning if shapes are lost
**Unknown format handling:**
- Unknown formats backed up before creating empty document
- Raw document keys logged for investigation
**Also fixed:**
- Keyboard shortcuts dialog error (tldraw i18n objects)
- Google Workspace integration now first in Settings > Integrations
