-## Database Migration Status
-
-**Current Status**: The application is undergoing a migration from Dexie (IndexedDB) to SQLite using absurd-sql. This migration is in **Phase 2** with a well-defined migration fence in place.
-
-### Migration Progress
-- ✅ **SQLite Database Service**: Fully implemented with absurd-sql
-- ✅ **Platform Service Layer**: Unified database interface across platforms
-- ✅ **Settings Migration**: Core user settings transferred
-- ✅ **Account Migration**: Identity and key management
-- 🔄 **Contact Migration**: User contact data (via import interface)
-- 📋 **Code Cleanup**: Remove unused Dexie imports
-
-### Migration Fence
-The migration is controlled by a **migration fence** that separates legacy Dexie code from the new SQLite implementation. See [Migration Fence Definition](doc/migration-fence-definition.md) for complete details.
-
-**Key Points**:
-- Legacy Dexie database is disabled by default
-- All database operations go through `PlatformServiceMixin`
-- Migration tools provide controlled access to both databases
-- Clear separation between legacy and new code
