- Datenmodell: users/{uid}, households/{id} mit memberUids, plants/locations als Subcollections
- StreamProvider liefern Live-Daten, Repositories kapseln Schreibzugriffe
- Login-Screen mit Registrierung (legt Haushalt automatisch an), Logout in Einstellungen
- Router-Redirect bei Login/Logout, firestore.rules mit Haushalts-Prinzip
- Tests auf firebase_auth_mocks + fake_cloud_firestore umgestellt
- Verifiziert: analyze/test grün, Android-Debug-Build erfolgreich
