 - Added auth API tests driving a minimal multitenant-ready surface.
 - Implemented `loginWithPassword`, `logout`, and stubs in `src/api/auth.ts` to satisfy tests.
 - Refactored `useAuth` to add households and activeHousehold state, plus `loginWithPassword` and `logout`. Tests added and passing.
-- Added router tests and implemented feature-flagged nested routes and new public routes. Placeholders for onboarding/invitations added.
+- Added router tests and implemented slug-only nested routes and new public routes. Placeholders for onboarding/invitations added.
  - Implemented `useHousehold.ts`, Authorization provider in API client, minimal `HouseholdSwitcher.vue`, and mounted it. Replaced header injection test with path-scoped assertion.
 - Implemented JWT login/register in `auth.ts` and wired token to client provider. `useAuth` updated with households fetching. `currentUser` refactored to token-only refresh plus households load.
 - Router guard updated to handle public/multitenant routing and redirects.

  - Backend updated OpenAPI and codegen has been run:
    - Many endpoints are now path-scoped with `{householdSlug}` (recipes, meals, shopping, invitations (create), whoami).
    - Auth endpoints (login/register/refresh/logout) are fully typed; `refresh` returns only `{ accessToken, tokenType }`.
-   - Completed migration to typed path parameters; header injection removed; only small raw fetch helpers remain for endpoints not yet in OpenAPI (persons, parse, members list).
