# Identity Persistence Strategy

## Strategy

- DAL repository boundaries coordinate identity aggregate persistence operations.
- Dependency health checks are defined inside DAL boundaries.
- Storage and cache dependencies are modeled in DAL-owned contracts.
- gRPC translation stays at adapter interfaces and does not include persistence implementation.

## Constraints

- Identity persistence concerns do not leak to non-Thalos repositories.
- Service layer consumes DAL boundaries without owning persistence details.
- This stage defines contracts and ports only; no datastore implementation is introduced.
