+/// Notification Service Extension for Nextcloud push-v2.
+///
+/// Architecture: Nextcloud pushes an E2E-encrypted notification to the
+/// MarianumConnect proxy, which forwards it via FCM to this device as an
+/// `alert` push with `mutable-content: 1`. That flag makes iOS spin up this
+/// extension *before* showing the notification, giving us ~30 s (wall clock,
+/// shared with the CPU budget) to decrypt the payload and replace the
+/// placeholder alert with the real content.
+///
+/// The FCM proxy places the two relevant fields at the top level of the APNs
+/// payload (mirrored into `request.content.userInfo`):
+///   - `subject`   base64( RSA-encrypted subject JSON ) — encrypted with THIS
+///                 device's public key, so we decrypt with our private key.
+///   - `signature` base64( SHA-512-with-RSA over the *encrypted* subject bytes )
+///                 — signed by the per-user server key we stored at registration.
+///
+/// Key material lives in the shared (App Group) keychain, written by the Dart
+/// side via flutter_secure_storage with
+/// `IOSOptions(groupId: kPushKeychainGroup, accessibility: first_unlock)`:
+///   - `push_device_private_key_pem`   crypton PKCS#8-in-"RSA PRIVATE KEY" PEM
+///   - `push_server_public_key_pem`    SPKI "PUBLIC KEY" PEM (from NC)

+/// failure, malformed JSON, timeout) we deliver the untouched placeholder
+/// content. We never crash and never deliver empty content.

+   │  verifiziert Signatur → entschlüsselt subject → setzt Titel/Body/Category
+   ▼
+iOS zeigt die fertige Notification
+```
+
+- **Verschlüsselung:** OAEP-SHA1 (NC-32-Default) mit Fallback PKCS#1 v1.5.
+- **Signatur:** `SHA512withRSA` über die **base64-dekodierten (verschlüsselten)**
+  subject-Bytes, geprüft mit dem per-User-Server-Public-Key aus der Registrierung.
+- **Dart-Referenz:** `lib/push/` — insb. `push_decryptor.dart` (Krypto-Spiegel),
+  `push_secure_storage.dart` (Keychain-Optionen), `push_keypair.dart` (Keyformat),
+  `push_registration_store.dart` (was group-scoped gespeichert wird),
+  `push_registration.dart` (`_persistNativeAuthContext`).
+- **Backend-Referenz:** MarianumConnect-Service `marMobileApi`, Endpunkte
+  `push-proxy/notifications` (NC→Proxy) und `PUT/DELETE me/push-device`.
+- **Talk-Actions (Antworten / Als gelesen markieren):** werden **nativ** im
+  `AppDelegate` per `URLSession` an die Talk-OCS-API geschickt, weil bei einer
+  Notification-Action nicht garantiert ist, dass die Flutter-Engine läuft.

+
+---
+
+## 3. Xcode-Checkliste (auf dem Mac)
+
+> **Stand 2026-07-07:** Abschnitte 3.1–3.2 (Target anlegen, Dateien zuordnen) sind
+> bereits **programmatisch** erledigt (via `xcodeproj`-Gem). Der unsignierte Build
+> aller Targets läuft durch (`flutter build ios --no-codesign`), die
+> `NotificationServiceExtension.appex` wird korrekt in `Runner.app/PlugIns/`
+> eingebettet. **Offen bleiben nur noch Signing/Capabilities (3.3–3.4, 3.6)** —
+> die brauchen den Apple-Developer-Account und einen signierten Build/Archive.
+> Die 3.1/3.2-Anleitung unten bleibt als Referenz stehen (falls das Target mal neu
+> aufgesetzt werden muss).
+
+### 3.1 Target anlegen
+1. `ios/Runner.xcworkspace` in Xcode öffnen (nicht `.xcodeproj`).
+2. **File → New → Target… → iOS → Notification Service Extension**.
+3. **Product Name exakt: `NotificationServiceExtension`** (der
+   `NSExtensionPrincipalClass` in der Info.plist ist
+   `$(PRODUCT_MODULE_NAME).NotificationService` — bei abweichendem Namen zerbricht
+   das). Language: Swift. „Embed in Application": Runner.
+4. Beim Dialog „Activate scheme?" → Activate.
+5. **Bundle Identifier:** `eu.mhsl.marianum.mobile.client.NotificationServiceExtension`
+   (Muster wie bei den bestehenden Extensions).
+6. **Deployment Target = 15.0** (identisch zum Runner; im `post_install` des
+   Podfiles wird ohnehin alles auf 15.0 gezwungen).
+
+### 3.2 Generierte Dateien durch die vorhandenen ersetzen
+- Xcode legt eine eigene `NotificationService.swift` und `Info.plist` im
+  Target-Ordner an. **Beide aus dem Projekt entfernen** („Move to Trash" für die
+  frisch generierten) und stattdessen die bereits vorhandenen Dateien hinzufügen:
+  - `NotificationService.swift`, `PEM.swift` → **Target Membership: nur NSE**.
+  - `Info.plist` → in den **Build Settings** des NSE-Targets als
+    `INFOPLIST_FILE = NotificationServiceExtension/Info.plist` setzen (bzw. die
+    vorhandene Datei als Info.plist des Targets referenzieren).
+  - `NotificationServiceExtension.entitlements` → in Build Settings
+    `CODE_SIGN_ENTITLEMENTS = NotificationServiceExtension/NotificationServiceExtension.entitlements`.
+
+### 3.3 Capabilities (in **beiden** Targets: Runner **und** NSE)
+- **App Groups:** `group.eu.mhsl.marianum.mobile.client.widget` aktivieren.
+  (Beim Runner ist die Group bereits vorhanden; beim NSE neu hinzufügen.)
+- **Keychain Sharing:** Keychain-Group `group.eu.mhsl.marianum.mobile.client.widget`
+  hinzufügen. Die Entitlement-Dateien enthalten das schon als
+  `keychain-access-groups`; über die Capabilities-UI stellst du sicher, dass das
+  Provisioning-Profil es abdeckt.
+- Prüfen, dass die Capabilities-UI **keine** doppelten/abweichenden Einträge
+  erzeugt hat (Xcode schreibt gern in die `.entitlements`; danach Abschnitt 4
+  gegenchecken).
+
+### 3.4 Signing
+- Beide Targets: **Team** = dasselbe wie Runner. Automatic Signing an, oder die
+  passenden Profile wählen. Der App-Identifier-Prefix (Team-ID) muss identisch
+  sein, sonst greift die Keychain-Group nicht.
+
+### 3.5 Pods / Podfile
+- Die NSE ist **komplett selbst-enthalten** (`Foundation`, `Security`,
+  `UserNotifications` — alles System-Frameworks). **Kein** Pod-Target nötig.
+- Prüfen, ob irgendein Flutter-Plugin explizit ein NSE-Target im Podfile verlangt
+  (aktuell **nein** — `firebase_messaging` braucht keins). Falls doch mal nötig:
+  im Podfile analog zur `Share Extension` einen `target
+  'NotificationServiceExtension' do inherit! :search_paths end`-Block ergänzen,
+  danach `pod install`.
+- Nach dem Anlegen einmal `cd ios && pod install` laufen lassen (aktualisiert die
+  Workspace-Referenzen).
+
+### 3.6 aps-environment (Production!)
+- `ios/Runner/Runner.entitlements` hat aktuell `aps-environment = development`.
+  **Für TestFlight/Release muss `production` aktiv sein.** Das wurde hier bewusst
+  **nicht** hart umgestellt, um den Debug-Flow nicht zu brechen.
+- Empfehlung: über die **Capabilities → Push Notifications** und die
+  Build-Konfiguration steuern (Xcode setzt beim Archive automatisch `production`,
+  wenn das Profil ein Distribution-Profil ist). Beim Archive-Export kontrollieren,
+  dass in der finalen `.ipa` `aps-environment = production` steht (siehe 5.2).
+
+---
+
+## 4. Ermittelte Keychain-Details (verbindlich)
+
+Die Dart-Seite schreibt mit
+`IOSOptions(groupId: 'MY55VF3KPG.eu.mhsl.marianum.mobile.client.push', accessibility: first_unlock)`.
+
+> **Wichtig (Stand 2026-07-07):** Als Keychain-Access-Group wird **nicht** mehr die
+> App-Group (`group.*`) genutzt, sondern eine **team-prefixed** Group
+> (`$(AppIdentifierPrefix)eu.mhsl.marianum.mobile.client.push`). Grund: Die
+> Xcode-verwalteten Provisioning-Profile gewähren als `keychain-access-groups`
+> nur `<TeamID>.*` — eine `group.*`-App-Group fällt da **nicht** drunter, was
+> Automatic Signing mit „doesn't match the entitlements file's value for the
+> keychain-access-groups entitlement" abbricht. Runner und NSE teilen die Group,
+> weil sie mit demselben Team (`MY55VF3KPG`) signieren. Der `MY55VF3KPG.`-Prefix
+> ist der stabile AppIdentifierPrefix und in Dart/Swift hart hinterlegt.
+
+Aus dem Quellcode von **`flutter_secure_storage_darwin` 0.3.2** (gepinnt in
+`pubspec.lock`) ergibt sich die exakte Ablage im Keychain:
+
+| Keychain-Attribut | Wert |
+|-------------------|------|
+| `kSecClass` | `kSecClassGenericPassword` |
+| `kSecAttrAccount` | der Dart-**Key**, **wortwörtlich** (kein Hash, kein Prefix) |
+| `kSecAttrService` | **nicht gesetzt** (die `IOSOptions` setzen kein `accountName`) |
+| `kSecAttrAccessGroup` | `MY55VF3KPG.eu.mhsl.marianum.mobile.client.push` (team-prefixed) |
+| `kSecAttrAccessible` | `kSecAttrAccessibleAfterFirstUnlock` (aus `first_unlock`) |
+| Wert (`kSecValueData`) | **rohe UTF-8-Bytes** des Strings (PEM/Passwort im Klartext) |
+
+**Deshalb** fragt die Swift-Seite (`keychainString(...)` in NSE **und**
+AppDelegate) exakt so ab: `GenericPassword` + `kSecAttrAccount = <key>` +
+`kSecAttrAccessGroup` + `kSecMatchLimit=One` + `kSecReturnData=true`, **ohne**
+`kSecAttrService`. (Ein gesetztes `kSecAttrService` würde nicht matchen.)
+
+### Konkrete Einträge (Account-Namen)
+
+| Account (`kSecAttrAccount`) | Inhalt | Geschrieben von | Genutzt von |
+|-----------------------------|--------|-----------------|-------------|
+| `push_device_private_key_pem` | Device-**Private**-Key, PEM | `push_keypair.dart` | **NSE** (entschlüsseln) |
+| `push_device_public_key_pem` | Device-Public-Key, SPKI-PEM | `push_keypair.dart` | — (nur Registrierung) |
+| `push_server_public_key_pem` | **Server**-Public-Key (per User), SPKI-PEM | `push_registration_store.dart` | **NSE** (Signatur prüfen) |
+| `push_device_identifier` | NC Device-Identifier | `push_registration_store.dart` | Dart |
+| `push_registered_fcm_token` | FCM-Token der Registrierung | `push_registration_store.dart` | Dart |
+| `nextcloud_app_password` | NC App-Password | `account_data.dart` | **AppDelegate** (Basic-Auth) |
+| `nextcloud_username` | NC Username | `push_registration_store.dart` (**neu**) | **AppDelegate** (Basic-Auth) |
+| `nextcloud_base_url` | z.B. `https://cloud.marianum-fulda.de` | `push_registration_store.dart` (**neu**) | **AppDelegate** (OCS-URL) |
+
+> `username` und `password` (Realpasswort) liegen in AccountDatas **Default**-Storage
+> **ohne** `groupId` → nur im primären Access-Group der App, **für die NSE
+> unsichtbar**. Deshalb werden `nextcloud_username` + `nextcloud_base_url` bei
+> jeder `register()`-Runde zusätzlich **group-scoped** geschrieben. Das
+> App-Password lag schon immer group-scoped.
+
+### Schlüsselformate (kritisch für das PEM-Parsing)
+
+`crypton` (2.2.1) erzeugt die Keys:
+- **Private Key:** Label `-----BEGIN RSA PRIVATE KEY-----`, der DER-Body ist aber
+  **PKCS#8** `PrivateKeyInfo` (SEQ{ INTEGER version, SEQ algId, OCTET STRING
+  pkcs1 }) — **nicht** rohes PKCS#1! `SecKeyCreateWithData` will bei RSA aber
+  **rohes PKCS#1**. `PEM.pkcs1PrivateKey(fromPkcs8:)` strippt den PKCS#8-Wrapper
+  (extrahiert den OCTET-STRING-Inhalt).
+- **Public Key** (Device **und** der von NC gelieferte Server-Key): Label
+  `-----BEGIN PUBLIC KEY-----`, DER = **SPKI** `SubjectPublicKeyInfo`.
+  `PEM.pkcs1PublicKey(fromSpki:)` extrahiert den BIT-STRING-Inhalt und wirft das
+  führende `0x00`-Byte (unused bits) weg → PKCS#1 `RSAPublicKey`.
+
+---
+
+## 5. Verifikation auf dem Mac
+
+### 5.1 Build
+- `flutter clean && flutter pub get`
+- `cd ios && pod install`
+- In Xcode: **beide** Targets bauen. NSE-Target-Scheme separat bauen, um Swift-
+  Fehler früh zu sehen.
+- Auf echtem Gerät installieren (Push funktioniert **nicht** im Simulator).
+
+### 5.2 aps-environment im Archive prüfen
+- Product → Archive → Distribute (oder `.ipa` exportieren) → `.ipa` entpacken →
+  `codesign -d --entitlements :- Payload/Runner.app` → muss
+  `aps-environment = production` zeigen.
+
+### 5.3 Testbenachrichtigung (schneller Smoke-Test, ohne NC-Krypto)
+- In den App-Einstellungen → Benachrichtigungen → **Testbenachrichtigung**
+  (Backend `POST me/push-device/test`). Erwartung: Alert „Testbenachrichtigung /
+  Push-Benachrichtigungen funktionieren! 🎉". Testet Registrierung + FCM +
+  Rendering — die NSE ist hier **nicht** beteiligt (Connect-Push, kein
+  `mutable-content`).
+
+### 5.4 Echte Talk-Nachricht (End-to-End inkl. NSE)
+- Gerät sperren. Von einem Zweitaccount eine Talk-Nachricht schicken.
+- **Erwartung:** Banner mit **echtem Absender + Nachrichtentext** (nicht der
+  Platzhalter „Neue Benachrichtigung / Tippen zum Öffnen"). Long-press →
+  Actions „Antworten" + „Als gelesen markieren".
+- „Antworten" → Text senden → Nachricht erscheint im Chat (nativ via URLSession),
+  Chat wird als gelesen markiert.
+- Alternativ auf der NC-Instanz: `occ notification:test-push --talk <user> -v`.
+
+### 5.5 Woran erkenne ich, ob die NSE lief?
+- **NSE lief & OK:** echter Absender/Text im Banner.
+- **NSE lief nicht / Fehler:** Platzhalter-Text bleibt stehen. Das ist der
+  bewusste Fallback (nie leer, nie Crash).
+- **Logs:** Über die macOS-**Console.app** das Gerät wählen und nach `[NSE]` bzw.
+  `[Talk action]` filtern (`NSLog`-Ausgaben). Oder in Xcode: Debug → Attach to
+  Process → `NotificationServiceExtension`.
+
+---
+
+## 6. Bekannte Fehlerbilder + Fixes
+
+| Symptom | Wahrscheinliche Ursache | Fix |
+|---------|-------------------------|-----|
+| NSE greift gar nicht (immer Platzhalter, auch bei Talk) | `mutable-content` fehlt / Signing des NSE-Targets kaputt / Bundle-ID falsch | Backend-`FcmMessageFactory` setzt `mutable-content:1` (prüfen). NSE-Target-Signing + Provisioning prüfen. Bundle-ID = `…client.NotificationServiceExtension`. |
+| Banner zeigt Platzhalter trotz Talk | PEM-Parsing/Padding schlägt fehl | Console.app nach `[NSE] SecKeyCreateWithData failed` / `could not decrypt`. Prüfen, dass Private-Key wirklich als PKCS#8-in-„RSA PRIVATE KEY" ankommt (crypton). OAEP↔PKCS1-Fallback ist schon drin. |
+| `[NSE] no device private key in keychain` | Keychain-Group greift nicht | In **beiden** Targets Keychain Sharing + App Group aktiv? Team-ID identisch? Access-Group-String exakt `group.eu.mhsl.marianum.mobile.client.widget`? |
+| Signatur schlägt immer fehl | Falscher/kein Server-Public-Key | `push_server_public_key_pem` vorhanden? (wird bei `register()` gesetzt). Notfalls: ohne Server-Key überspringt die NSE die Prüfung — bleibt sie hängen, ist der Key da aber falsch geparst. |
+| Reply-Action tut nichts | Credentials fehlen / Delegate-Konflikt (s.u.) | Console.app nach `[Talk action]`. `nextcloud_username`/`_app_password`/`_base_url` im Keychain? App einmal neu einloggen (schreibt sie via `register()`). |
+| Reply wird **doppelt** gesendet | AppDelegate **und** ein Plugin behandeln dieselbe Action | Der AppDelegate returnt bei TALK_REPLY/TALK_MARK_READ **ohne** `super`-Aufruf, das Plugin sieht die Action also nicht. Falls doch doppelt: prüfen, ob `flutter_local_notifications` auf iOS separat als Delegate registriert ist. |
+
+### ⚠️ Delegate-Ownership (wichtigster Verifikationspunkt)
+
+`FlutterAppDelegate` konformiert (über `FlutterAppLifeCycleProvider`) zu
+`UNUserNotificationCenterDelegate` und **leitet** `userNotificationCenter(...)` an
+die registrierten Plugins weiter (firebase_messaging,
+flutter_local_notifications). Der `AppDelegate` setzt sich in
+`didFinishLaunching` als `UNUserNotificationCenter.current().delegate = self`,
+**überschreibt** die beiden Delegate-Methoden und ruft für alles **außer** den
+zwei Talk-Actions `super` auf — dadurch bleibt das Plugin-Forwarding intakt. Das
+ist der fragilste Teil und **muss auf dem Gerät verifiziert werden**:
+- Normale Push-Taps müssen weiterhin ins richtige Chat/Ziel navigieren
+  (läuft über `super` → Plugins).
+- Foreground-Darstellung von FCM darf nicht kaputtgehen (`willPresent` wird hier
+  bewusst **nicht** überschrieben, läuft komplett über `super`/Plugins).
+- Sollte ein Plugin den Delegate **nach** `didFinishLaunching` erneut übernehmen
+  (und damit unsere Talk-Actions abfangen), das Setzen von
+  `UNUserNotificationCenter.current().delegate = self` an einen späteren Punkt
+  verschieben (z. B. nach dem ersten Dart-Frame). Ohne Gerät nicht abschließend
+  testbar.
+
+> **Compile-Hinweis:** `override` an den beiden `userNotificationCenter`-Methoden
+> ist korrekt, weil die Methoden über das von `FlutterAppDelegate` adoptierte
+> Protokoll `FlutterAppLifeCycleProvider : UNUserNotificationCenterDelegate`
+> sichtbar sind (verifiziert im Flutter-3.44-Engine-Header). `super.userNotification…`
+> ist daher aufrufbar.
+
+---
+
+## 7. Offene TODOs / bewusste Einschränkungen
+
+1. **Delete-Handling auf iOS (best effort).** Delete-Pushes kommen als silent
+   `background`-Pushes (`content-available`, **kein** `mutable-content`) → die NSE
+   läuft dafür **nicht**. Das Wegräumen erledigt der Flutter-Background-Handler
+   (`PushMessageHandler`) bzw. ein Sweep beim App-Öffnen. Erreicht doch mal ein
+   Delete-Subject die NSE, **kann** sie die Notification **nicht** unterdrücken
+   (eine NSE muss immer *irgendeinen* Content liefern) — sie lässt den Platzhalter
+   stehen und loggt. Kein Fix möglich, dokumentierte iOS-Limitierung.
+2. **Rich-Detail via OCS (spätere Erweiterung).** v1 lädt **nichts** nach. Optional
+   könnte die NSE bei Talk `GET …/ocs/v2.php/apps/notifications/api/v2/notifications/{nid}`
+   mit dem App-Password abrufen, um Avatar/Rich-Subject anzuzeigen (Timeout < 25 s,
+   innerhalb des NSE-Budgets). Nicht implementiert.
+3. **`aps-environment = production`** ist noch nicht hart gesetzt (Abschnitt 3.6) —
+   vor dem Release erledigen und im Archive gegenchecken (5.2).
+4. **Keychain-Access-Group-Schreibweise (gelöst 2026-07-07).** Die Entitlements
+   listen `$(AppIdentifierPrefix)eu.mhsl.marianum.mobile.client.push` als
+   `keychain-access-groups` (team-prefixed, **keine** App-Group). Damit greift das
+   `<TeamID>.*` der Xcode-Profile und Automatic Signing läuft ohne Portal-Änderung
+   durch (verifiziert: `flutter build ios --release` signiert Runner **und** NSE
+   mit `MY55VF3KPG.eu.mhsl.marianum.mobile.client.push`). Der frühere App-Group-
+   Ansatz (`group.*`) scheiterte an genau diesem Profil-Matching. Falls der
+   Keychain-Zugriff zur Laufzeit doch scheitert (Status `-34018` /
+   `errSecMissingEntitlement`), prüfen, dass Dart (`push_secure_storage.dart`) und
+   Swift (`AppDelegate.swift`, `NotificationService.swift`) **exakt denselben**
+   vollqualifizierten Group-String verwenden.
