 `Home.razor` + `Home.razor.cs` now act as a small gateway that switches between loading, anonymous auth, and workspace views.
 Authenticated application state and behavior were moved into `Components/Pages/Workspace.razor`, while reusable concern UI remains under `Components/Pages/HomeControls/`.
 
+## Why does the workspace header sometimes show "Loading user..." briefly?
+
+`Workspace` initializes authenticated session data after the first render (`OnAfterRenderAsync`). During that first render pass, the header now intentionally shows a null-safe fallback label instead of dereferencing user fields before `/api/me` has been loaded.
+
 ## Why is auth form state kept in `AuthSection` instead of `Home`?
 
 Auth inputs, validation, and submit workflows are transient UI concerns, so they now live in `AuthSection`. `Home` keeps shared session/workspace state and cross-control refresh/orchestration only.

 - Legacy TypeScript frontend/runtime artifacts: removed
 - Home was simplified to a minimal gateway (`Loading` / `Anonymous` / `Workspace`) in a single `Home.razor.cs` class.
 - The authenticated workspace shell/state/behavior was moved to `Components/Pages/Workspace.razor`.
+- Workspace header user identity rendering is now null-safe during first render (`Loading user...` fallback until `/api/me` loads).
 - Concern controls now own their local form state and mutation workflows; the workspace host handles shared cross-control state refresh.
 - Skill create/edit flow is now owned by `CharacterPanel` (where characters and their skills are presented together).
