 - Added an application identity store and infrastructure adapter over the existing identity cache/persistence composition, then routed identity reads/writes through pure domain mappings; full Auth tests pass in `113faef`.
 - Extracted identity request normalization/validation into `application/identity`, preserving Persian-digit conversion and existing validation behavior while leaving protobuf mutation at the interface boundary; full Auth tests pass in `2d5ab3d`.
 - Added identity ownership/person-verification application contracts and infrastructure adapters, runtime-wired both real and configured fake-provider paths, and preserved existing error mapping; full Auth tests and vet pass in `75c2e0d`. A006 is complete.

+### `A007` — explicit Auth composition
+
+- Replaced the eleven-argument positional constructor with a typed `Dependencies` graph assembled in `cmd/serve.go`, making OTP, JWT/session, permission, and identity infrastructure wiring explicit at bootstrap.
+- The legacy two-argument constructor remains only as an A008 compatibility shim; full Auth tests and vet pass in `7d7871b`. A007 is complete.
 - A006 remains in progress: permission repository wiring and identity application orchestration still need extraction.
 - A005 remains in progress: JWT validation, session checks, refresh-token flow, and broader authentication orchestration still need application ports and adapters.
