# Android Persistence Standards
## **Priority: P0**
## Implementation Guidelines
### Room
- **Async**: Return `Flow<List<T>>` for queries, use `suspend` for Write/Insert.
- **Entities**: Keep simple `@Entity` data classes. Map to Domain models in Repository.
- **Transactions**: Use `@Transaction` for multi-table queries (Relations).
### DataStore
- **Usage**: Replace `SharedPreferences` with `ProtoDataStore` (Type-safe) or `PreferencesDataStore`.
- **Scope**: Inject singleton instance via Hilt.
## Anti-Patterns
- **No IO on Main Thread**: Room handles dispatchers, but verify Flow is collected off-main.
- **No @Entity in UI Layer**: Map to Domain or UI models in Repository.
