 - Runtime-wired the permission repository adapter and routed permission initialization lookup/creation plus super-admin listing through the domain port, retaining legacy fallback; full Auth tests pass in `5b61adf`.
 - Added an application role-permission reader and infrastructure adapter over the existing Redis/Postgres cache-aside path, then routed standard-user permission reads through it; full Auth tests pass in `24722cb`.
 - 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`.
 - 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.
