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.
