Build the React consumer over the fail-closed view-mode logic so an admin can view the app as each of the three homes (User/Admin/SysAdmin) and step down to a plain User-Side home. - ViewModeProvider holds the raw requested home (seeded from localStorage, shape-checked only) and resolves it live against is_admin on every render, so a demotion or transient /me failure collapses to the User home with no flash, while an unentitled value is never stored or applied. - RoleSwitcher renders only for admins (availableViewModes > 1); switching re-gates the choice and navigates to the chosen home's root. - AppShell drives its sidebar from sectionsForView(view, isAdmin), which only ever narrows visibleSections — an admin viewing as a user sees a plain user's sidebar and lands on the Dashboard at /. - landingPathForView / viewModeLabelKey added to the logic layer (tested); view_* and view_switch_label i18n keys added for en-US and zh-CN. Placement note: the spec calls for a top-right avatar control, but the panel has no desktop top bar, so the switcher lives in the sidebar foot beside the user strip. Functionally complete; placement is not yet spec-parity.
