+Android Architektur (Kotlin + Jetpack Compose) — Vorschlag
+
+Packages/Module Struktur:
+- app/ (Android-App module)
+  - src/main/java/de/harheimertc/
+    - ui/
+      - navigation/ (NavGraph, Routes)
+      - screens/ (HomeScreen, TermineScreen, SpielplanScreen, GalleryScreen, ContactScreen, AuthScreens, CMS Screens)

+    - domain/ (UseCases, Business-Logic)
+    - util/ (Extensions, DateUtils, ImageUtils)
+    - auth/ (AuthManager, Passkeys helper)
+
+Wichtige Dateien:
+- `MainActivity.kt` — Hosts Compose NavHost
+- `AppTheme.kt` — Compose Material3 Theme mit Token-Mapping
+- `NetworkModule` (Hilt) — Retrofit + OkHttp + Auth Interceptor
+- `Repository` Layer — entkoppelt UI von Netz
+- `Room` Entities — für Caching von Termine/News/Galerie
+
+Auth-Strategie:
+- AuthRepository verwaltet Login/Logout, `checkAuth()` (mirroring `/api/auth/status`).
+- Token/Cookie-Speicherung: `EncryptedSharedPreferences` für Tokens oder `CookieJar` mit OKHttp-Client.
+- Passkeys: `Fido2Client` wrapper + Bridge zu Server-API (Formate prüfen).
+
+Build / Module Tipps:
+- Start mit Single Module `app/` und später evtl. `:data`, `:domain` Trennung.
+- Verwende Gradle Kotlin DSL (build.gradle.kts).
+
+Diese Architekturdatei wurde generiert; ich kann nun ein initiales Gradle-Kotlin-Scaffold erzeugen. Soll ich das direkt in `android-app/` ablegen? (Ja/Nein)

+Android App — Kotlin (Jetpack Compose) Plan und Abhakliste
+
+Kurz: Ziel ist eine native Android-App mit Kotlin + Jetpack Compose, die die Web-UI 1:1 abbildet (Farben, Typografie, Funktionalitäten). Diese Datei enthält Architekturentscheidungen, empfohlene Bibliotheken und eine detaillierte Abhakliste (schrittweise).
+
+1) Zusammenfassung der Entscheidungen
+- Plattform: Native Android
+- Sprache: Kotlin
+- UI-Toolkit: Jetpack Compose (Compose Material3)
+- Architektur: MVVM mit `ViewModel` + Kotlin Coroutines + Flow
+- DI: Hilt
+- HTTP-Client: Ktor Client oder Retrofit + OkHttp (empfohlen: Retrofit für breite Community-Docs)
+- Bild-Loading: Coil
+- Lokale DB / Caching: Room + DataStore (Preferences)
+- Background/Sync: WorkManager
+- Auth: kurzlebiges JWT-Access-Token plus rotierendes, widerrufbares Refresh-Token pro Android-Gerätesitzung; Speicherung in `EncryptedSharedPreferences`/Android Keystore; Unterstützung für Passkeys (Android Passkeys / WebAuthn Interop über FIDO2 APIs)
+- Auth-Sicherheitsentscheidung: kein statischer App-Key bzw. kein in der APK hinterlegtes Client-Secret. Native Apps können ein gemeinsames Secret nicht vertraulich halten. Optional später: Refresh-Sitzung an ein pro Installation im Android Keystore erzeugtes Schlüsselpaar binden.
+- Rich-Text: WebView-basierte Anzeige; Editoren: ggf. hybride Lösung (Server-side HTML editor + WebView) oder `RichEditor`-Libs
+- Crash-Reporting & Monitoring: Firebase Crashlytics oder Sentry
+
+2) Design & Farben
+- Material Theme (Material3) mit Farben aus `tailwind.config.js` (Primary + Accent).
+- Fonts: Inter & Montserrat via Google Fonts (Download/Bundle oder Play-Services-Download at runtime).
+- Mapping: Tailwind-Token → `colors.xml` / Compose `Color` tokens.
+
+3) Empfohlene Abhängigkeiten (erste Implementierung)
+- androidx.compose.* (ui, material3, navigation)
+- androidx.lifecycle:lifecycle-viewmodel-ktx
+- com.google.dagger:hilt-android
+- retrofit2 + converter-moshi / kotlinx-serialization
+- io.coil-kt:coil-compose
+- androidx.room:room-runtime + room-ktx
+- androidx.work:work-runtime-ktx
+- androidx.datastore:datastore-preferences
+- com.google.android.gms:play-services-auth (für passkeys falls nötig)
+- io.sentry:sentry-android (optional)
+

+- Release-Zertifikat erzeugen und Digital Asset Links für native Android-Passkeys veröffentlichen.
+- Die noch fehlenden öffentlichen Routen aus `10a` und die Newsletter-Screens aus `10b` nativ portieren.
+- Saisonwahl für Mannschaftsübersicht/-details wie in der Web-UI ergänzen.
+- Weitere offene Punkte nach Priorität abarbeiten; die API-/Bearer-Basis für die portierten geschützten Android-Screens ist abgeschlossen.
+
+7) Umsetzungsprotokoll
+- 2026-05-27: Webnahe Startseite mit öffentlichen Live-Daten umgesetzt; Hilt/Moshi-App-Verdrahtung ergänzt.
+- 2026-05-27: `Termine` und `Spielplan` als native Screens umgesetzt; Spielplan unterstützt Saison, Wettbewerb, Mannschaft, Ergebnis und zweizeilige Gruppeninformation.
+- 2026-05-27: `Mitgliedschaft` mit Antrag/PDF-Abruf sowie Passwort-`Login`/`Logout` umgesetzt; offene Auth-Härtung separat ausgewiesen.
+- 2026-05-27: Tokens verschlüsselt persistiert; Session-Wiederherstellung sowie Logout per Bearer-Token in den Auth-Endpunkten ermöglicht.
+- 2026-05-27: Registrierung und Passwort-Reset an die vorhandenen Auth-Endpunkte angebunden.
+- 2026-05-27: Product-Flavors `local`, `instantTest` und `production` eingerichtet; lokale Basis-URL ist per Gradle-Parameter überschreibbar.
+- 2026-05-27: Gradle-Heap/Worker für Flavor-Builds festgelegt, nachdem paralleles D8/KSP mit dem 512-MiB-Standardheap nicht ausreichend Speicher hatte.
+- 2026-05-27: Lokales Testsetup gegen Emulator geprüft; bei IPv6-gebundenem Nuxt-Dev-Server wird die von Nuxt ausgegebene Network-URL per `LOCAL_API_BASE_URL` verwendet.
+- 2026-05-27: Adaptive Navigation umgesetzt; Tablet-Layouts ab `600dp` zeigen Header und Hauptmenue dauerhaft, Smartphone-Layouts behalten die vorhandene Navigation.
+- 2026-05-27: Platzhalterlogo in der Android-Navigation durch das vorhandene Harheimer-TC-Weblogo als skalierte lokale PNG-Ressource ersetzt.
+- 2026-05-27: Web-Navigation und `pages/` vollständig inventarisiert; Tablet-Haupt-/Subnavigation für die öffentlichen Bereiche strukturell angeglichen und alle fehlenden Screens einzeln in die Portierungsliste aufgenommen.
+- 2026-05-27: Tablet-Header auf Web-Verhalten angepasst (Bereichswechsel öffnet Startseite und Submenü) und die native ActionBar zugunsten des App-Headers entfernt.
+- 2026-05-27: Navigation mit Live-Mannschaftslinks, öffentlicher Galerie-Sichtbarkeit und rollenabhängigem `Intern` ergänzt; Mannschaftsübersicht/-detail sowie Training, Trainer und Anfänger nativ portiert.
+- 2026-05-27: Mannschaftsdetail um die Web-Untertabs `Matches` und `Tabelle` erweitert; Tabellenzeilen werden aus `/api/spielplan/table` geladen und die eigene Mannschaft hervorgehoben.
+- 2026-05-27: Tabellenraster in den Mannschaftsdetails mit gemeinsamen Spaltenbreiten für Tablet und Smartphone ausgerichtet; die Zustandswiederherstellung dynamischer Mannschaftslinks korrigiert.
+- 2026-05-27: Die verbleibenden öffentlichen Screens aus Punkt 10 portiert: Verein/CMS-Inhalte, Vorstand, Satzung/PDF, Links, Vereinsmeisterschaften mit Personenbild-Dialog, Spielsysteme und TT-Regeln.
+- 2026-05-27: Architektur für dauerhaftes Android-Login festgelegt: kein eingebetteter App-Key, sondern kurzlebige Access-Tokens und rotierende, widerrufbare Refresh-Tokens pro Gerätesitzung; optionale spätere Gerätebindung per Keystore-Schlüsselpaar.
+- 2026-05-27: Dauerhaftes Android-Login umgesetzt: Android-Logins erhalten 15-Minuten-Access-Tokens und rotierende Refresh-Tokens; Token-Hashes, Wiederverwendungswiderruf, Logout-/Reset-/Deaktivierungswiderruf sowie verschlüsselte App-Speicherung und automatischer OkHttp-Refresh sind implementiert.
+- 2026-05-27: Native Profilseite des Mitgliederbereichs umgesetzt; `/api/profile` akzeptiert nun Bearer-Tokens, die App kann Profil-/Sichtbarkeitsdaten bearbeiten und Passwortänderungen auslösen.
+- 2026-05-27: Login leitet in der Android-App nun direkt zur Mitgliederbereich-Übersicht weiter; `/mitgliederbereich` ist nativ mit Kacheln und Geburtstagsliste umgesetzt, `/api/birthdays` akzeptiert Bearer-Tokens.
+- 2026-05-28: 10d und 10e abgeschlossen: Mitgliederliste, interne News, API-Doku sowie alle CMS-Routen sind nativ angebunden; relevante Mitglieder-/News-/CMS-Endpunkte akzeptieren Bearer-Tokens.
+- 2026-05-28: 10a und 10b abgeschlossen: Impressum, Newsletter-An-/Abmeldung und Newsletter-Statusseiten sind nativ umgesetzt; Legacy-/Doppelrouten im Android-NavGraph auf native Screens abgebildet. Abgleich `pages/` gegen Android-Routen ergab keine verbleibenden Platzhalter-Webseiten. `/anlagen` wurde anschließend als ungenutzte und inhaltlich falsche Seite in Web und Android entfernt.
+- 2026-05-28: Android-Passkeys umgesetzt: Login nutzt Android Credential Manager mit den bestehenden WebAuthn-Optionen, das native Profil kann Passkeys erstellen/entfernen, und die Backend-Passkey-Endpunkte akzeptieren Bearer-Tokens sowie erzeugen beim Android-Passkey-Login rotierende Refresh-Sitzungen. Für Produktion fehlt noch die Domain-App-Verknüpfung per Digital Asset Links mit Release-Zertifikat.
+- 2026-05-28: Punkte 15 und 16 umgesetzt: Gemeinsame `RichText`-Komponente rendert HTML-Inhalte nativ in CMS-/News-Screens; Formularvalidierung wurde mit Inline-Feldfehlern für Kontakt, Auth, Newsletter, Profil und Mitgliedschaft ergänzt.
+- 2026-05-28: Rich-Text-Editor nativ umgesetzt: `/cms/inhalte` kann Über-uns, Geschichte, TT-Regeln und Satzung mit Android-Toolbar bearbeiten; gespeichert wird weiterhin HTML in `seiten.*` über `PUT /api/config`, kompatibel zur Web-/Quill-Ausgabe.
+- 2026-05-28: Punkt 14 umgesetzt: Android-Galerie nutzt den strukturierten `/api/galerie/list`-Response, lädt Bilder über Coil aus `/api/media/galerie/:id`, und Admin/Vorstand kann Bilder nativ auswählen, lokal auf JPEG/2000px/85% komprimieren und per Multipart an `/api/galerie/upload` senden.
+- 2026-05-28: Punkt 18 umgesetzt: `strings.xml` für Deutsch und Englisch ergänzt, App-Label und neue Galerie-Upload-UI auf Ressourcen umgestellt; i18n-Check weist die bestehenden älteren Compose-Harttexte als spätere Nachmigration aus.
+- 2026-05-28: Punkt 11 abgeschlossen: Android sendet Bearer-Tokens zentral per OkHttp-Interceptor; die portierten geschützten Backend-Endpunkte akzeptieren Cookie- oder Bearer-Authentifizierung. Die Web-UI bleibt absichtlich bei HttpOnly-Cookie-Sessions und muss nicht auf Bearer umgestellt werden.
+- 2026-05-28: Caching-Teil von Punkt 17 und MVP-D umgesetzt: OkHttp cached öffentliche GET-Antworten und nutzt gecachte Antworten offline, Coil nutzt denselben authentifizierten Client plus Memory-/Diskcache. Geschützte Daten werden bewusst nicht unverschlüsselt im HTTP-Diskcache persistiert.
+- 2026-05-28: Testbasis für Punkt 20 begonnen: JVM-Unit-Tests für E-Mail- und ISO-Datum-Validierung ergänzt; `:app:testLocalDebugUnitTest` läuft mit `compileSdk 35` grün.
+- 2026-05-28: Punkte 17, 19, 21 und 23 weiter umgesetzt: geschützte Mitglieder-/CMS-Daten werden verschlüsselt in Keystore-gestützten Preferences gecacht und bei Ladefehlern genutzt; Galerie-Accessibility und Thumbnail-Decoding verbessert; Sentry-Android 8.42.0 über optionalen `SENTRY_DSN`-Gradle-Parameter integriert.
+- 2026-05-29: Play-Store-Listing-Vorbereitung ergänzt: eigenständige Web-Datenschutzseite (`/datenschutz`) sowie Asset-/Anonymisierungs-Skripte und Anleitung in `android-app/PLAYSTORE_ASSETS.md` hinzugefügt.
+
+8) Android-Testumgebungen
+- Lokal im Emulator: `./gradlew :app:installLocalDebug` verwendet `http://10.0.2.2:3100/` und die App-ID `de.harheimertc.local`.
+- Lokal, wenn `10.0.2.2` nicht erreichbar ist: `./gradlew :app:installLocalDebug -PLOCAL_API_BASE_URL=http://<NUXT-NETWORK-HOST>:3100/`; die passende URL steht in der `npm run dev`-Ausgabe (hier `http://torstens:3100/`).
+- Test-Instanz: `./gradlew :app:installInstantTestDebug` verwendet `https://harheimertc.tsschulz.de/` und die App-ID `de.harheimertc.test`.
+- Produktion: `./gradlew :app:installProductionDebug` verwendet `https://harheimertc.de/` und die App-ID `de.harheimertc`.
+- Nur APKs erzeugen: `./gradlew :app:assembleLocalDebug :app:assembleInstantTestDebug :app:assembleProductionDebug`.
+
+8a) Aktueller Teststatus & Troubleshooting (Stand: 2026-05-28)
+
+- **Status:** `:app:assembleAndroidTest` läuft durch; `:app:connectedAndroidTest` ist derzeit instabil und schlägt bei Instrumentation-Läufen fehl.
+- **Beobachtete Probleme:**
+    - Kompilationsfehler in `LoginScreenTest.kt` wegen `HiltTestActivity` (Unresolved reference). Workaround: `createAndroidComposeRule<ComponentActivity>()` + `setContent{}` verwenden, damit `assembleAndroidTest` durchläuft.
+    - Laufzeit-/Device-Probleme bei `connectedAndroidTest`: `com.android.ddmlib.SyncException: Remote object doesn't exist!` und `DELETE_FAILED_INTERNAL_ERROR` beim Deinstallieren von Test-APKs.
+    - `AndroidTestLogcatPlugin` wirft `FileNotFoundException` für erwartete Log-/Crash-Dateien, weil Gradle/UTP manche Device-Artefakte nicht zuverlässig pulled.
+    - Einzelne Instrumentation-Tests (z. B. `CmsActivateResendTest`, `GalleryScreenTest`) zeigen Assertion-Fehlschläge — diese sollten isoliert reproduziert werden.
+- **Kurzfristige Empfehlungen (nicht ausführen):**
+    - Emulator neu starten und sicherstellen, dass keine veralteten Test-APKs installiert sind.
+    - Manuell: `adb uninstall` der Test-Pakete, dann frisches `adb install -r` des Test-APKs und gezielter Einzeltest via:
+
+        `adb shell am instrument -w -e class <test-class>#<testMethod> de.harheimertc.test/androidx.test.runner.AndroidJUnitRunner`
+
+        parallel `adb logcat -v time > /tmp/harheimertc_live_logcat.txt` laufen lassen, um vollständige Logs zu speichern.
+    - Falls UTP/ddmlib `SyncException` weiter auftritt: Gradle-Parallelität reduzieren, Test-Plugins (z. B. `AndroidTestLogcatPlugin`) temporär deaktivieren oder Tests in kleinere Gruppen splitten.
+- **Offene Test‑To‑Dos:**
+    - Reproduzierbaren Einzeltest-Run mit vollständigem `logcat` erfassen (derzeit vom Nutzer pausiert).
+    - Flaky Tests isolieren und Hilt/KSP-Setup prüfen, damit `HiltTestActivity`-Importe nicht mehr fehlschlagen.
+    - Langfristig: Tests aufteilen, flaky tests markieren und CI-Job für androidTests gegen UTP-Transient-Fehler härten.
+
+9) Dauerhaftes Android-Login: Architektur und Umsetzung
+- Stand der Umsetzung: Android-Logins erhalten ein ca. 15 Minuten gültiges JWT und eine serverseitig prüfbare Refresh-Sitzung; Access-Tokens mit Sitzungs-ID werden bei widerrufener Gerätesitzung abgelehnt. Web-Logins verwenden weiterhin das bisherige Cookie-JWT, bis ein browserseitiger Refresh-Flow ergänzt ist.
+- Ziel: Ein Benutzer bleibt auf einem bekannten Gerät angemeldet, ohne dass ein langfristig gültiges Bearer-JWT oder ein extrahierbares App-Secret verwendet wird.
+- Token-Modell:
+     - Access-Token: JWT mit kurzer Laufzeit, Zielwert ca. 15 Minuten; wird für normale API-Requests als Bearer-Token verwendet.
+     - Refresh-Token: kryptografisch zufälliges, undurchsichtiges Token mit längerer Laufzeit, Zielwert z. B. 90 Tage mit Erneuerung bei aktiver Nutzung.
+     - Server speichert ausschließlich den Hash des Refresh-Tokens zusammen mit `sessionId`, `userId`, `createdAt`, `lastUsedAt`, `expiresAt`, `revokedAt` und optional Gerätebezeichnung.
+- Backend-Arbeitspaket:
+     - Login-Antwort um `accessToken`, `refreshToken`, `sessionId` und Ablaufmetadaten erweitern; bestehendes `token` nur befristet kompatibel halten.
+     - `POST /api/auth/refresh` implementieren: gültiges Refresh-Token konsumieren, rotieren und ein neues Token-Paar zurückgeben.
+     - Token-Wiederverwendung erkennen: Wird ein rotiertes Refresh-Token erneut präsentiert, die betroffene Token-Familie bzw. Gerätesitzung widerrufen.
+     - `POST /api/auth/logout` auf Widerruf der Gerätesitzung erweitern; optional Endpunkte zum Anzeigen und Widerrufen eigener Geräte-Sitzungen vorsehen.
+     - Kontodeaktivierung und Passwortänderung müssen sämtliche Refresh-Sitzungen des Benutzers widerrufen.
+     - Rate-Limits und Audit-Events für Login, Refresh-Erfolg/-Fehlschlag, Wiederverwendung und Widerruf ergänzen.
+- Android-Arbeitspaket:
+     - `AuthRepository` auf Access-Token, Refresh-Token und Session-ID erweitern; Speicherung weiter über Keystore-geschützte Preferences.
+     - `ApiService`/DTOs um Refresh-Request und Token-Paar-Antwort ergänzen.
+     - Einen OkHttp-`Authenticator` einsetzen, der auf `401` einmalig ein Access-Token erneuert, parallele Refreshes synchronisiert und den ursprünglichen Request wiederholt.
+     - Beim App-Start zunächst Access-Token prüfen und bei Ablauf transparent mit dem Refresh-Token erneuern; nur bei fehlgeschlagenem Refresh zum Login zurückkehren.
+     - Beim Logout lokale Tokens auch bei Netzwerkfehler entfernen; serverseitiger Widerruf erfolgt best effort bzw. bei nächster Konnektivität.
+- Sicherheitsregeln:
+     - Kein gemeinsamer App-Key und kein statisches Client-Secret in Sourcecode, `BuildConfig` oder APK.
+     - Refresh-Tokens nie im Klartext serverseitig speichern oder protokollieren.
+     - Nur HTTPS für Test-/Produktionsumgebungen; Token-Werte nicht in Logging-Interceptors ausgeben.
+     - Optional nach MVP: App erzeugt pro Installation ein Keystore-Schlüsselpaar; Backend bindet Refresh-Sitzungen an den öffentlichen Schlüssel und prüft signierte Refresh-Anfragen.

+
+**CMS-Verbesserungsplan (Analyse → Umsetzung)**
+
+Ziel: Alle `cms/*`-Screens von rudimentärem Status zu vollständigen, getesteten Admin-Tools weiterentwickeln. Fokus: Datenintegrität, Berechtigungen, bessere UI/UX, Offline-Verhalten und Tests.
+
+Kurzüberblick (3 Phasen):
+- Phase A — Analyse (1-2 Tage): Inventar aller CMS-Endpunkte, fehlende CRUD-Workflows identifizieren, Prioritäten setzen (News, Benutzer, Kontaktanfragen, Newsletter, Config). Ergebnis: Aufgabenliste mit Aufwandsschätzung.
+- Phase B — Implementierung MVP (1-2 Wochen): Kernfunktionen pro Bereich implementieren (News CRUD mit RichText-Vorschau, Benutzerliste + Rollen-Edit, Kontaktanfragen Detail & Antwort-Workflow, Newsletter-Gruppen-Management, Config-Editor inklusive Satzung-PDF-Feld). Unit- / Integrationstests für ViewModels.
+- Phase C — Harden, UX & Tests (1 Woche): Validierung, Fehlermeldungen, Offline-Caching (verschlüsselt für geschützte Daten), Compose-UI-Tests, Accessibility-, Performance-Feinschliff.
+
+Detaillierte Aufgaben (priorisiert):
+- A1: Audit `CmsViewModel`-State vs. Backend-Responses — fehlen Felder/Fehlerfälle? (bereits teilweise umgesetzt)
+- A2: Prüfen, ob API-Fehler (4xx/5xx) sauber an `FormMessages`/UI gemeldet werden — Standardisiere Fehlermeldungen.
+- A3: Prüfen, ob `NativeRichTextEditor` HTML speichert, das Web-Editor-kompatibel bleibt (Quill/HTML). Schreibe Roundtrip-Tests.
+- B1: News-Management
+    - B1.1: News-CRUD: Create/Update/Delete mit Vorschau (RichText-Preview) und Validierung (Titel Pflicht, Inhalt Mindestlänge)
+    - B1.2: Bulk-Aktionen: Sichtbar/Unsichtbar/ExpiresAt setzen
+    - B1.3: Unit-Tests für `NewsViewModel` + `CmsViewModel`-Integrationspfad

+    - B4.2: Gruppenverwaltung (CRUD) + Subscribe/Unsubscribe-Preview
+- B5: Config / Seiten (Inhalte)
+    - B5.1: Sichern/Zurücksetzen von Seiteninhalten mit Undo-Hinweis
+    - B5.2: Satzung: PDF-Upload-Feld und native PDF-Viewer-Integration (falls serverseitig gespeichert)
+    - B5.6: Android-Startseite weiter ausbauen: Nutzer sollen Elemente und Reihenfolge der Startseite selbst zusammenstellen koennen; Detailkonzept und Feinschliff folgen spaeter
+- B6: Diagnostics / Passwort-Reset-Diagnose
+    - B6.1: Detail-View mit exportierbaren Logs (bei Bedarf)
+- C1: Offline-/Caching-Strategie
+    - C1.1: Verschlüsseltes lokales Caching für CMS-Daten (EncryptedSharedPreferences/Room)
+    - C1.2: Sync-Strategie: lokale Änderungen buffernd senden, Konflikt-UI
+- C2: Tests & CI
+    - C2.1: ViewModel-Unit-Tests für alle CMS-Flows
+    - C2.2: Compose-UI-Tests für kritische Pfade (News erstellen, Benutzerrolle ändern, Config speichern)
+    - C2.3: androidTest Hilt-Stubs erweitern (falls nötig)
+
+Minor UX-Verbesserungen (parallel möglich):
+- konsistente Buttons/Labels (`Speichern` vs `Inhalt speichern`), Ladezustand-UI, einzeilige Success-/Error-Banner, Inline-Validierungen.
+
+Deliverables & Milestones:
+- M1 (nach Analyse): Priorisierte Aufgabenliste + Schätzung (mehrere PRs)
+- M2 (nach MVP-Implementierung): News + Benutzer + ContactRequests + Config Editor + Tests (smoke)

+- Hardening + Tests: 3–5 Arbeitstage
+
+Wenn du willst, trage ich die einzelnen Subtickets in unserem lokalen Issue-Tracker (oder als separate TODOs) ein und beginne mit A1/A2.
+
+**TODO (zum Abhaken) — CMS-Implementierung**
+
+- [x] A1: Audit `CmsViewModel` vs Backend-Responses (Fehleraggregation implementiert)
+- [x] A2: Standardisiere API-Fehlerdarstellung in UI (`FormMessages` / globale Errors)
+- [x] A3: Roundtrip-Tests `NativeRichTextEditor` ↔ Backend-HTML (Kompatibilität / Quill)
+- [x] B1: News-Management

+     - [x] B2.1: Rollen-Edit (Inline oder Detail-Dialog)
+     - [x] B2.2: Aktiv/Inaktiv Toggle, Resend-Invite
+     - [x] B2.3: Tests für Pagination/Leere Listen
+
+- [x] B3: Kontaktanfragen
+    - [x] B3.1: Detailansicht + Antwort-Option
+    - [x] B3.2: Status-Filter + Archiv
+
+- [ ] B4: Newsletter
+    - [x] B4.1: Entwurf → Senden Flow mit Preview
+    - [x] B4.2: Gruppenverwaltung (CRUD)
+
+ - [x] B5: Config / Seiten
+        - Web‑Status: Die Web‑UI bietet bereits umfassende CMS‑UIs für `cms/startseite`, `cms/vereinsmeisterschaften`, `cms/sportbetrieb` und `cms/einstellungen` (Drag&Drop, CSV‑Import/Export, Tabbed‑UIs, ImageUpload, native‑like Modals). `cms/startseite` speichert `homepage.sections` via `PUT /api/config`, `vereinsmeisterschaften` arbeitet mit CSV‑Export/Import, `sportbetrieb` kapselt Termine/Mannschaften/Spielpläne in Tabs, `einstellungen` ist ein umfangreicher Config‑Editor.
+        - Android‑Status: Implementiert — die Android‑App enthält native CMS‑Screens (`CmsStartseiteScreen`, `CmsVereinsmeisterschaftenScreen`, `CmsSportbetriebScreen`, `CmsEinstellungenScreen`) mit Save/Load‑Flows via `CmsViewModel`.
+        - Umsetzung (B5.x):
+            - [x] B5.1: `cms/startseite` (Startseiten‑Layout) — Reorderable/Visibility + Save → `PUT /api/config` (via `CmsViewModel`).
+            - [x] B5.2: `cms/vereinsmeisterschaften` — CSV‑Parser/CSV‑Save integration and modal CRUD (native UI present).
+            - [x] B5.3: `cms/sportbetrieb` — Tabbed UI reusing `Termine`, `Mannschaften`, `Spielplan` components.
+            - [x] B5.4: `cms/einstellungen` — Tabbed config editor with Vereinsdaten/Training/Trainer/Mitgliedschaft and save.
+            - [x] B5.5: Roundtrip & Tests — basic ViewModel unit tests and roundtrip checks exist; Compose UI smoke tests remain for hardening.
+            - [x] B5.6: Startseite weiter ausgebaut — zusaetzliche Elemente (`training`, `links`, `vereinsmeisterschaften`) sind konfigurierbar; Android kann Reihenfolge/Sichtbarkeit lokal speichern und Web nutzt Marker (`cookie`, `eingeloggt`) mit marker-spezifischer Persistenz: `eingeloggt` wird als individuelles User-Setting serverseitig gespeichert, `cookie` wird ausschliesslich im Browser-Cookie gehalten. Neu umgesetzt: konfigurierbare Startseiten-Widgets vom Typ `spielplan_team` (Saison + Mannschaft beim Hinzufuegen waehlbar, spaeter jederzeit aenderbar, mehrfach pro Startseite moeglich, persistiert ueber `key` + `config`).
+
+ - [x] B6: Diagnostics / Passwort-Reset-Diagnose (Export/Detail)
+        - Web‑Status: `cms/passwort-reset-diagnose` zeigt vollständige Diagnose‑UI mit Suche, Maskierung, Filter (nur Auffälligkeiten) und listbaren Reset‑Versuchen; Backend: `/api/cms/password-reset-diagnostics` liefert `matchingUsers`, `attempts`, `retentionHours`.
+        - Android‑Status: umgesetzt — native Diagnose‑UI mit Suche (`email`/Name), Filter `Nur Auffälligkeiten`, `matchingUsers`‑Liste mit Schnellfilter, detaillierter Schrittansicht je Versuch (Zeit/Schritt/Status/Grund), Refresh und Share‑Export der maskierten Logs.
+        - Konkrete Android‑ToDos (B6.x):
+            - [x] B6.1: Implementieren Suche + Filter UI, Rendering der `attempts` mit Zeitstempeln, Status‑Badges und Details.
+            - [x] B6.2: Logs exportieren / share (falls API Export unterstützt) und Datenschutz: E‑Mail Maskierung beibehalten.
+
+- [x] C1: Offline-/Caching-Strategie (verschlüsselt für geschützte CMS-Daten)
+    - Umgesetzt: EncryptedSharedPreferences-basierter Offline-Cache mit Zeitstempel/TTL pro Cache-Key (CMS standard 24h, Reset-Diagnose 6h).
+    - Umgesetzt: Fallback auf verschlüsselte Cache-Daten bei Ladefehlern nur innerhalb der TTL, um veraltete geschützte CMS-Daten zu begrenzen.
+    - Umgesetzt: Gezielte Cache-Invalidierung bei schreibenden CMS-Operationen (Konfiguration, Benutzerverwaltung, Kontaktanfragen, Newsletter, interne News), damit Offline-Daten nach Änderungen konsistent bleiben.
+    - Umgesetzt: Passwort-Reset-Diagnose-Cache wird nur für den Standardfilter (ohne Suchbegriff) verwendet, um falsche Treffer bei gefilterten Diagnosen zu vermeiden.
+- [x] C2: Tests & CI
+    - [x] C2.1: ViewModel-Unit-Tests für CMS-Flows (`CmsViewModel.load()` / `saveConfig()`)
+        - Status: `:app:testLocalDebugUnitTest` läuft grün; `CmsViewModelTest` wurde auf aktuelle Repository-Signaturen und vollständige `load()`-Abhängigkeiten (inkl. `vereinsmeisterschaften`) aktualisiert.
+    - [x] C2.2: Compose-UI-Tests für kritische Flows
+        - Status: neuer Instrumentation-Test für `CmsPasswordResetDiagnosticsScreen` ergänzt (`diagnosticsScreen_showsFilterAndAttemptDetails`) und gezielt per `connectedLocalDebugAndroidTest` erfolgreich ausgeführt.
+    - [x] C2.3: androidTest Hilt-Stubs erweitern (falls nötig)
+        - Status: androidTest-ApiService-Stubs und Hilt-Testmodul auf neue `passwordResetDiagnostics(email, failedOnly)`-Signatur erweitert; `:app:assembleLocalDebugAndroidTest` läuft grün.
+
+Markiere die Items, wenn erledigt — ich kann die einzelnen Punkte jetzt in Branches/PRs umsetzen.

+ANDROID App - 1:1 Portierung der Web-UI (TODO)
+
+Ziel: Die Web-UI des Projekts 1:1 in eine native (oder cross-platform) Android-App überführen, inklusive Farben, Designsystem und aller Funktionalitäten.
+
+1) Analyse Codebasis & Assets
+- Analysiere `package.json`, `nuxt.config.js`, `tailwind.config.js` und zentrale Server-/API-Endpunkte.
+- Liste alle verwendeten Farben, CSS-Variablen, Tailwind-Konfigurationen.
+- Sammle alle statischen Assets: Bilder, Icons, SVGs, Fonts, PDF-Dokumente.
+- Identifiziere dynamische Komponenten: Formulare, Rich-Text-Editor, Uploads, Kalender, Navigation.
+
+2) Projektziele und Scope
+- Entscheide: Native Android (Kotlin/Jetpack Compose) oder Cross-Platform (React Native, Flutter, Kotlin Multiplatform).

+Repo API Endpoints — Übersicht
+
+Hinweis: Viele Frontend-Requests verwenden relative Pfade (`/api/...`) und Nuxt's `NUXT_PUBLIC_BASE_URL`.
+
+Öffentliche/Frontend-Endpunkte (häufig genutzt):
+- GET /api/config
+- GET /api/news-public
+- GET /api/news
+- GET /api/termine
+- GET /api/spielplaene
+- GET /api/spielplan
+- GET /api/mannschaften
+- GET /api/galerie
+- GET /api/media/galerie/{id}
+- GET /api/personen/{filename}?width=...&height=...
+- POST /api/contact
+- POST /api/news (CMS)
+
+Galerie / Media:
+- POST /api/galerie/upload
+- GET /api/galerie/list
+- GET /api/galerie/[id]
+- DELETE /api/galerie/[id]
+
+Authentifizierung:
+- POST /api/auth/login
+- POST /api/auth/logout
+- POST /api/auth/register
+- POST /api/auth/reset-password
+- GET  /api/auth/status
+- POST /api/auth/passkeys/authentication-options  (Passkeys start: server returns WebAuthn options)
+- POST /api/auth/passkeys/login  (Passkeys finish: credential verification)
+
+CMS / geschützte Endpunkte (erfordern Auth):
+- GET /api/cms/* (z.B. /api/cms/users/list, /api/cms/contact-requests)
+- POST /api/cms/save-csv
+- POST /api/cms/upload-spielplan-pdf
+- POST /api/cms/satzung-upload
+- POST /api/members, DELETE /api/members, POST /api/members/bulk
+- POST /api/membership/update-status
+- POST /api/termine-manage, DELETE /api/termine-manage, GET /api/termine-manage
+
+Weitere (Datei-Uploads, Personen):
+- POST /api/personen/upload
+- GET /api/app/version
+- Various CMS-specific routes under /api/cms
+
+Auth-Anforderungen & Hinweise:
+- Frontend nutzt `$fetch('/api/...')` (Nuxt) — serverseitig vermutlich Session-Cookie oder JWT.
+- `stores/auth.js` verwendet `/api/auth/status` to check login state and `passkeyLogin()` which calls `/api/auth/passkeys/*`.
+- Passkeys-Flow verwendet `@simplewebauthn/browser` on web; Android port should support FIDO2 / Passkeys (Google Passkeys API) or provide password fallback.
+- CMS- und Manage-Endpunkte require authentication and role checks (admin/vorstand etc.).
+
+Empfehlung für Android-Client:
+- Nutze Retrofit/OkHttp mit anpassbarem Auth-Interceptor (Cookie-jar or token storage). Prüfe, ob Server bevorzugt Cookies (then use CookieJar) or JWT Authorization header.
+- Implementiere Passkeys via Android FIDO2 / Passkeys APIs as optional fast-login path; for servers expecting WebAuthn payloads adapt encoding accordingly.

+# Google Play: Zugang für die App-Prüfung
+
+In der Play Console unter **Richtlinien und Programme → App-Inhalte → App-Zugriff / Anmeldedaten** angeben, dass einige Funktionen eine Anmeldung erfordern. Eine neue Anleitung mit Titel `Harheimer TC review account` anlegen.
+
+## Konto auf dem Backend der eingereichten App einrichten
+
+Nach Deployment dieser Änderungen im Projektverzeichnis des entsprechenden Servers ausführen:
+
+```bash
+node scripts/setup-playstore-review.js
+```
+
+Das Skript liest die dortige `.env` einschließlich `ENCRYPTION_KEY`, sichert die bisherige Benutzerdatei und erstellt ein aktives, ausgeblendetes Mitgliedskonto. Standardadresse: `playstore-review@harheimertc.invalid`. Dies ist bewusst kein echtes Postfach. Das zufällig erzeugte Passwort wird einmal ausgegeben und muss sicher abgelegt werden. Bei erneutem Aufruf bleibt es unverändert. Optional können `PLAYSTORE_REVIEW_EMAIL` und `PLAYSTORE_REVIEW_PASSWORD` gesetzt werden; ein explizites Passwort aktualisiert das bestehende Review-Konto. Kein reguläres Konto wird umgewandelt.
+
+In der Play Console die ausgegebene E-Mail-Adresse und das Passwort eintragen. Zusätzliche Anweisungen auf Englisch:
+
+> Open the app and go to Login. Sign in with the email address and password provided above. This account is already activated and provides access to the member features. No registration, email verification, one-time code or approval is required. Please stay signed in while testing forms. Outgoing emails triggered by this account are suppressed by the server. When a form asks for an email address, use the review account email provided above, including when testing while signed out.
+
+Die Zugangsdaten dauerhaft gültig halten. Das Konto ist ein Mitglied, kein CMS-Administrator.
+
+## Versandsperre
+
+Alle SMTP-Versandstellen verwenden dieselbe serverseitige Sperre:
+
+- Für authentifizierte Konten mit `accountType: playstore_review` oder der konfigurierten `PLAYSTORE_REVIEW_EMAIL` wird kein SMTP-Versand ausgeführt, auch bei abweichender Formularadresse.
+- Mails an die Review-Adresse sowie Kontaktmails mit dieser Antwortadresse werden auch ohne Anmeldung unterdrückt. Registrierung und Mitgliedsanträge prüfen zusätzlich die Formularadresse. Gemischte Empfängerlisten mit einem Review-Konto werden vollständig unterdrückt.
+- `MAIL_DELIVERY_DISABLED=true` unterdrückt sämtliche SMTP-Mails einer Installation. Die PM2-Testkonfiguration setzt dies standardmäßig; Produktion bleibt ohne diese Einstellung aktiv. Nach Konfigurationsänderungen den Backend-Prozess mit aktualisierter Umgebung neu starten.
+- `DEBUG=true` allein verhindert keinen Mailversand.
+
+Die Versandsperre ist keine isolierte Demo-Datenbank: Formulare können weiterhin Daten speichern und Push-Benachrichtigungen auslösen. Ohne Anmeldung und mit einer fremden Formularadresse lässt sich eine Anfrage keinem Review-Konto zuordnen. Für vollständig mailfreie Tests daher eine separate Testinstanz mit `MAIL_DELIVERY_DISABLED=true` verwenden und sicherstellen, dass der eingereichte App-Build dieses Backend nutzt.
