## Role in the architecture
- Zero-trust between services with mTLS.
- RBAC and scopes enforced at API edge.
- Least-privilege DB roles and secret management.

## Considerations
- Throughput vs. latency trade-offs.
- Failure domains and retry/backoff strategies.
- Data model ownership and boundaries.
