+# Authentication Domain
+
+Handles user authentication (login and registration) against the configured server endpoint. Provides the login, register, and user-bar UI components.

+## Service overview
+
+`AuthenticationService` resolves the API base URL from `ServerDirectoryFacade`, then makes POST requests for login and registration. It does not hold session state itself; after a successful login the calling component stores `currentUserId` in localStorage and dispatches `UsersActions.setCurrentUser` into the NgRx store.

+
+## Login flow
+
+```mermaid

+    participant User
+    participant Login as LoginComponent
+    participant Auth as AuthenticationService
+    participant SD as ServerDirectoryFacade
+    participant API as Server API
+    participant Store as NgRx Store
+
+    User->>Login: Submit credentials
+    Login->>Auth: login(username, password)
+    Auth->>SD: getApiBaseUrl()
+    SD-->>Auth: https://server/api
+    Auth->>API: POST /api/auth/login
+    API-->>Auth: { userId, displayName }
+    Auth-->>Login: success
+    Login->>Store: UsersActions.setCurrentUser
+    Login->>Login: localStorage.setItem(currentUserId)
+```
+
+## Registration flow
+
+Registration follows the same pattern but posts to `/api/auth/register` with an additional `displayName` field. On success the user is treated as logged in and the same store dispatch happens.
+
+## User bar
+
+`UserBarComponent` reads the current user from the NgRx store. When logged in it shows the user's display name; when not logged in it shows links to the login and register views.
