 - Injected the verifier into IAM and refresh-token flows through runtime composition, retaining fallback for compatibility; full Auth tests pass in `6c5b8cc`.
 - Extracted active/expiry session policy into `application/auth` with focused tests; integration into IAM/session retrieval remains for the next checkpoint (`424741c`).
 - Added a domain-session `SessionStore` contract, infrastructure adapter over the legacy cache/persistence composition, and runtime wiring for IAM retrieval; full Auth tests pass in `d744ffc`. The adapter deliberately preserves existing Redis-expiry semantics without activating stricter status checks during the refactor.
+- Routed login and refresh-session persistence through the same application boundary with legacy fallback retained; full Auth tests and vet pass in `c15bcff`.
 - A005 remains in progress: JWT validation, session checks, refresh-token flow, and broader authentication orchestration still need application ports and adapters.
