# Home shell flow
|

|

After successful auth, `HomeComponent` renders a thin shell layout:
|
||||
|
||||
1. The header (`shell-header`) shows the page title and signed-in
|
||||
identity.
|
||||
2. When `shouldShowAdminNav({isAuthenticated, role})` returns `true`
|
||||
(see `frontend/src/app/features/home/home.shell.ts`) the admin nav
|
||||
link (`data-testid="nav-admin"`) is rendered.
|
||||
3. Child routes (e.g. `/admin` → `AdminUsersComponent`) render into the
|
||||
shell's `<router-outlet>`.
|
||||
4. `AdminUsersComponent` calls `AdminService.listUsers()` on init;
|
||||
loading, error, and the rendered list are exposed as Angular signals.
