Implement Room schemas and DataStore preferences with proper async patterns in Android. Use when the primary task is storage schema, DAO, migration, or preference isolation; defer auth-token/security storage, any CoroutineWorker/WorkManager task, Hilt graph wiring, and cache-policy design.

Android Persistence Standards
Priority: P0 (CRITICAL)
1. Configure Room Database
- Return
Flow<List<T>>for queries, usesuspendfor Write/Insert. - Keep
@Entitydata classes simple. Map to Domain models in Repository. - Use
@Transactionfor multi-table queries (Relations).
See DAO templates for Room DAO patterns.
2. Migrate to DataStore
- Replace
SharedPreferenceswithProtoDataStore(type-safe) orPreferencesDataStore. - Inject singleton DataStore instance via Hilt.
See DAO templates for DataStore migration patterns.
Anti-Patterns
- No IO on Main Thread: Room handles dispatchers, but verify Flow collected off-main.
- No @Entity in UI Layer: Map to Domain or UI models in Repository.

Infer the requesting operator's technical fluency from message content (never ask directly) and adapt register — business, hybrid, or technical — across SDLC workflow output. Use when starting sdlc, brainstorm-feature, plan-feature, verify-work, publish-notes, or session-report, or whenever a request's phrasing signals a non-technical or cross-stack operator.
