+# User Authentication Flow — Refresh Token

+    actor User
+    participant API as API Controller
+    participant Mediator as MediatR pipeline<br/>(ValidationBehavior)
+    box rgb(241,243,234) Handler Layer
+        participant RefreshHandler as RefreshTokenHandler
+        participant UserMgr as UserManager(ApplicationUser)
+        participant TokenSvc as TokenService

+        participant UserStore as DapperUserStore<br/>(IUserStore/IUserPasswordStore/IUserEmailStore)
+    end
+    participant DB as SQL Server
+
+    Note over UserMgr: ASP.NET Core Identity's UserManager replaces the deleted AuthRepository — handlers delegate to UserManager, which calls DapperUserStore (persistence) and Argon2PasswordHasher.

+    User->>API: POST /api/auth/refresh<br/>Header: X-Refresh-Token: {token}
+    activate API
+    API->>Mediator: Send(RefreshTokenCommand(refreshToken))
+    activate Mediator
+    Note right of Mediator: ValidationBehavior runs RefreshTokenValidator — refreshToken must be non-empty. Anonymous endpoint, no Bearer token required.

+        activate TokenSvc
+        TokenSvc->>JWT: ValidateRefreshTokenAsync(refreshToken)

+        Note right of JWT: Validates signature/expiry against the refresh token secret, extracts userId/username claims
