 Der Matrix-Stack ist im Selfhost-Compose direkt enthalten. Er umfasst Synapse, eine eigene PostgreSQL-Datenbank für Synapse, Redis, `.well-known/matrix`, coturn, LiveKit, den LiveKit-JWT-Service und Element Web. Das einfache Selfhost-Setup nutzt nur `DOMAIN`: Synapse läuft unter `https://DOMAIN/_matrix`, Matrix-Well-Known unter `https://DOMAIN/.well-known/matrix`, LiveKit unter `https://DOMAIN/livekit/sfu`, der JWT-Service unter `https://DOMAIN/livekit/jwt` und Element Web unter `https://DOMAIN/element`.
 
 Das Backend führt beim Containerstart standardmäßig `npm run migrate` aus. Setze `FEDEO_RUN_MIGRATIONS=false`, wenn du Migrationen bewusst manuell ausführen möchtest.

+# FEDEO Geräte-Agent
+
+Der FEDEO Geräte-Agent läuft lokal auf macOS, Linux oder Raspberry Pi OS. Er holt instanzweite Scan-Aufträge von FEDEO ab, führt sie auf einem lokal angeschlossenen Scanner aus und lädt das Ergebnis wieder in FEDEO hoch.
+
+Der Agent ist nicht an einen Mandanten gebunden. Jeder Auftrag enthält seinen Tenant selbst.
+
+## Voraussetzungen
+
+### macOS
+
+```bash
+brew install node sane-backends
+scanimage -L
+```
+
+Drucken nutzt später das macOS-Drucksystem/CUPS:
+
+```bash
+lpstat -p
+```
+
+### Linux und Raspberry Pi OS
+
+```bash
+sudo apt update
+sudo apt install -y nodejs npm sane-utils cups
+scanimage -L
+lpstat -p
+```
+
+## Konfiguration
+
+```bash
+cp .env.example .env
+nano .env
+```
+
+Wichtige Werte:
+
+```env
+FEDEO_URL=https://deine-fedeo-instanz
+FEDEO_AGENT_TOKEN=fedeo_agent_...
+FEDEO_SCANNER_NAME=
+FEDEO_POLL_SECONDS=5
+```
+
+Wenn `FEDEO_SCANNER_NAME` leer bleibt, verwendet `scanimage` den Standard-Scanner.
+
+## Entwicklung
+
+```bash
+npm install
+npm run dev
+```
+
+## OpenCV-Nachbearbeitung
+
+Für automatischen Zuschnitt, leichte Entzerrung, Rotation und Kontrastkorrektur kann die OpenCV-Pipeline aktiviert werden.
+
+```bash
+npm run setup:opencv
+```
+
+Konfiguration:
+
+```env
+FEDEO_SCAN_POSTPROCESS=true
+FEDEO_SCAN_POSTPROCESS_PROFILE=receipt
+FEDEO_SCAN_POSTPROCESS_PYTHON=/pfad/zum/agent/.venv-opencv/bin/python
+FEDEO_SCAN_POSTPROCESS_STRICT=false
+```
+
+Wenn `FEDEO_SCAN_POSTPROCESS_PYTHON` leer bleibt, verwendet der Agent automatisch `.venv-opencv/bin/python`, sofern diese Umgebung existiert. Falls OpenCV nicht installiert ist und `FEDEO_SCAN_POSTPROCESS_STRICT=false` gesetzt ist, lädt der Agent den Rohscan hoch, statt den Auftrag komplett fehlschlagen zu lassen.
+
+Profile:
+
+- `receipt`: Bons und schmale Belege werden bevorzugt hochkant zugeschnitten und kontrastiert.
+- `document`: allgemeine Dokumente mit Farberhalt und moderater Verbesserung.
+- `raw`: Zuschnitt/Entzerrung ohne starke Kontrastkorrektur.
+
+## Container-Betrieb
+
+Auf Linux und Raspberry Pi OS kann der Agent komplett im Container laufen. Dadurch bleiben Node.js, Python, OpenCV und SANE im Image. Auf dem Host werden dann nur Docker und Zugriff auf den USB-Scanner benötigt.
+
+```bash
+cp .env.example .env
+nano .env
+docker compose -f docker-compose.example.yml up --build
+```
+
+Wenn FEDEO lokal auf dem Docker-Host läuft, verwende im Container nicht `localhost`, sondern:
+
+```env
+FEDEO_URL=http://host.docker.internal:3100
+```
+
+Scanner im Container prüfen:
+
+```bash
+docker compose -f docker-compose.example.yml run --rm fedeo-device-agent scanimage -L
+```
+
+Wenn der Scanner nicht sichtbar ist, hilft je nach Gerät/Host manchmal `privileged: true` im Compose-Beispiel. Auf macOS ist Docker dafür nur eingeschränkt geeignet, weil Docker Desktop USB-Scanner normalerweise nicht direkt an Linux-Container durchreichen kann. Für macOS bleibt deshalb der native Agent oder später eine signierte App der bessere Weg.
+
+## Build
+
+```bash
+npm run build
+npm start
+```
+
+## FEDEO-Endpunkte
+
+Der Agent nutzt:
+
+- `POST /instance-agent/heartbeat`
+- `GET /instance-agent/scan-jobs/next`
+- `POST /instance-agent/scan-jobs/:id/status`
+- `POST /instance-agent/scan-jobs/:id/upload`
+
+## macOS Autostart
+
+Die Vorlage liegt unter `system/macos/com.fedeo.device-agent.plist`. Nach Anpassung der Pfade kann sie als LaunchAgent installiert werden:
+
+```bash
+mkdir -p ~/Library/LaunchAgents
+cp system/macos/com.fedeo.device-agent.plist ~/Library/LaunchAgents/
+launchctl load ~/Library/LaunchAgents/com.fedeo.device-agent.plist
+```
+
+## Linux Autostart
+
+Die Vorlage liegt unter `system/linux/fedeo-device-agent.service`.

+# Kommunikationslösung auf Basis des Matrix-Standards
+
+Dieser Entwurf beschreibt eine FEDEO-Kommunikationslösung für Chat, Anrufe und Videokonferenzen auf Basis des Matrix-Standards. Ziel ist eine souverän betreibbare Lösung, die Mandantenfähigkeit, Datenschutz, Rechteverwaltung und die bestehenden FEDEO-Workflows berücksichtigt.
+
+## Zielbild
+
+FEDEO erhält einen integrierten Kommunikationsbereich, der interne Zusammenarbeit und externe Kommunikation abdeckt:
+
+- Chat in Einzel-, Gruppen-, Projekt-, Vorgangs- und Kundenräumen
+- Audioanrufe aus Direktchats, Gruppenräumen und Kontakten
+- Videokonferenzen mit Bildschirmfreigabe und Einladungslinks
+- Ende-zu-Ende-verschlüsselte private Kommunikation
+- revisionsfähige Verknüpfung von relevanten Kommunikationsereignissen mit FEDEO-Objekten
+- optional föderierte Kommunikation mit externen Matrix-Organisationen
+
+Matrix wird dabei nicht als isolierter Messenger betrieben, sondern als Kommunikationsschicht neben dem bestehenden FEDEO-Backend.
+
+## Empfohlene Architektur
+
+```text
+Nutzerinnen und Nutzer
+  |
+  | FEDEO Web, Mobile App, optional Element Desktop/Mobile
+  v
+FEDEO Frontend
+  |
+  | FEDEO API, SSO, Rechte, Objektkontext
+  v
+FEDEO Backend
+  |
+  | Provisionierung, Webhooks, Audit-Metadaten
+  v
+Matrix Homeserver
+  |
+  +-- PostgreSQL für Matrix-Daten
+  +-- Redis für Worker und Caches
+  +-- Medien-Repository für Anhänge
+  +-- TURN/STUN für direkte Medienverbindungen
+  +-- MatrixRTC / LiveKit SFU für Gruppenanrufe und Videokonferenzen
+```
+
+### Kernkomponenten
+
+| Komponente | Empfehlung | Aufgabe |
+| --- | --- | --- |
+| Matrix Homeserver | Synapse | Standardnaher, bewährter Homeserver mit guter Betriebsdokumentation |
+| Matrix Client im FEDEO Web | Matrix JS SDK oder eingebetteter Element-Web-Ausschnitt | Chat, Raumliste, Nachrichten, Reaktionen, Anhänge |
+| Mobile Integration | Matrix SDK über FEDEO Mobile oder Deep Link zu Element X | Pushfähige mobile Kommunikation |
+| Identität | OIDC/SSO über FEDEO Auth, perspektivisch Matrix Authentication Service | Einheitlicher Login und zentrale Nutzerverwaltung |
+| Audio/Video | MatrixRTC mit Element Call und LiveKit SFU | Moderne Anrufe und Videokonferenzen |
+| NAT Traversal | coturn | STUN/TURN für stabile Medienverbindungen |
+| Reverse Proxy | bestehender Traefik-Ansatz | TLS, Routing, `.well-known/matrix/*` |
+| Administration | FEDEO Admin-Oberfläche plus Synapse Admin API | Nutzer, Räume, Richtlinien, Sperren |
+
+## Betriebsmodell
+
+Für FEDEO ist ein eigener Matrix-Homeserver pro Installation oder pro großer Betreiberinstanz sinnvoll. Der Matrix-Server sollte nicht öffentlich als offener Registrierungsserver betrieben werden. Nutzer werden ausschließlich durch FEDEO angelegt, aktualisiert und deaktiviert.
+
+Empfohlene Domains:
+
+- `app.example.com`: FEDEO Oberfläche
+- `matrix.example.com`: Matrix Client-Server und Federation API
+- `call.example.com`: Element Call / MatrixRTC
+- `livekit.example.com`: LiveKit SFU
+- `turn.example.com`: TURN/STUN
+
+Die öffentliche Matrix-Serverkennung kann trotzdem `example.com` lauten. Dafür werden `.well-known/matrix/client` und `.well-known/matrix/server` über Traefik ausgeliefert.
+
+## Mandantenmodell
+
+Matrix selbst ist raumbasiert, FEDEO ist mandantenbasiert. Deshalb sollte FEDEO die Mandantenlogik explizit auf Matrix-Räume und Spaces abbilden.
+
+### Räume und Spaces
+
+- Pro FEDEO-Mandant wird ein Matrix Space angelegt.
+- Projekte, Vorgänge, Helpdesk-Konversationen, interne Teams und Kundenkontakte werden als Räume im Mandanten-Space geführt.
+- Direkträume werden nutzerbezogen angelegt, aber über FEDEO mandantengebunden sichtbar gemacht.
+- Externe Räume erhalten einen klaren Status, zum Beispiel `intern`, `extern`, `kunde`, `lieferant`.
+
+### Raumalias-Konvention
+
+Beispiele:
+
+- `#tenant-<mandant>-team:example.com`
+- `#tenant-<mandant>-project-<projekt>:example.com`
+- `#tenant-<mandant>-ticket-<ticket>:example.com`
+- `#tenant-<mandant>-customer-<kunde>:example.com`
+
+Interne technische IDs sollten nicht als sichtbarer Anzeigename genutzt werden. Nutzerinnen und Nutzer sehen sprechende Namen wie `Projekt: Website Relaunch` oder `Kunde: Muster GmbH`.
+
+## Rechte und Rollen
+
+FEDEO bleibt führend für Berechtigungen. Matrix übernimmt die technische Durchsetzung im Raum.
+
+| FEDEO-Rolle | Matrix-Abbildung |
+| --- | --- |
+| Mandantenadmin | Space-Admin und Raumadmin |
+| Teamleitung | Moderatorin oder Moderator in Team- und Projekträumen |
+| Mitarbeitende | Mitglied mit Schreibrechten |
+| Externe Kontakte | Eingeschränkte Mitgliedschaft in ausgewählten Räumen |
+| Automationen | Application-Service- oder Bot-Nutzer mit minimalen Rechten |
+
+Änderungen an Rollen, Teams oder Mandantenzugehörigkeiten lösen im FEDEO-Backend eine Synchronisation mit Matrix aus. Beim Entzug eines Zugriffs wird die Person aus den betroffenen Räumen entfernt. Bei Ende-zu-Ende-verschlüsselten Räumen muss zusätzlich berücksichtigt werden, dass bereits erhaltene Nachrichten auf Geräten verbleiben können.
+
+## Chat
+
+Der Chat wird als erste Ausbaustufe umgesetzt.
+
+### Funktionen
+
+- Direktnachrichten
+- Gruppenräume
+- Mandanten-, Team-, Projekt- und Vorgangsräume
+- Datei- und Bildanhänge
+- Erwähnungen, Reaktionen und Lesestatus
+- Suche in nicht verschlüsselten Räumen über den Homeserver
+- lokale Suche in verschlüsselten Räumen über Client-Indizes
+- Verknüpfung von Nachrichten mit FEDEO-Objekten
+
+### Integration in FEDEO
+
+FEDEO sollte keine vollständige Kopie aller Nachrichten in der eigenen Datenbank speichern. Stattdessen speichert FEDEO nur Referenzen:
+
+- Matrix Raum-ID
+- Matrix Event-ID
+- FEDEO Objekt-Typ und Objekt-ID
+- Zeitstempel
+- beteiligter FEDEO-Nutzer
+- optionale Vorschau, falls Datenschutzrichtlinie dies erlaubt
+
+So bleibt Matrix das Kommunikationssystem, während FEDEO nachvollziehen kann, welche Kommunikation zu welchem Objekt gehört.
+
+## Audioanrufe
+
+Einzelanrufe können direkt über Matrix-VoIP in Direktchats gestartet werden. Der FEDEO-Client zeigt dafür in Kontakt-, Kunden-, Mitarbeitenden- und Chatansichten einen Anruf-Button.
+
+### Anforderungen
+
+- WebRTC-Unterstützung im Browser
+- STUN/TURN über coturn
+- Geräteauswahl für Mikrofon und Lautsprecher
+- Anrufbenachrichtigung im Web und mobil
+- Statusanzeige `verfügbar`, `beschäftigt`, `im Anruf`, `abwesend`
+
+Für klassische Telefonie kann später ein SIP-Gateway ergänzt werden. Das sollte jedoch getrennt von der ersten Matrix-Einführung betrachtet werden, damit Chat und WebRTC-Kommunikation nicht durch Telefoniekomplexität ausgebremst werden.
+
+## Videokonferenzen
+
+Für Gruppenanrufe und Videokonferenzen wird MatrixRTC mit Element Call und LiveKit empfohlen. Matrix übernimmt dabei Raumzustand, Identität, Berechtigungen und Signalisierung; LiveKit übernimmt als SFU die effiziente Medienverteilung.
+
+### Funktionen
+
+- Videokonferenzen aus Matrix-Räumen
+- spontane Besprechungen aus Projekten, Vorgängen oder Kundenakten
+- Bildschirmfreigabe
+- Einladungslink für externe Gäste
+- Wartebereich für externe Gäste
+- Moderationsrechte für Stummschalten, Entfernen und Raumverwaltung
+- optionale Aufzeichnung erst in einer späteren, gesondert freizugebenden Ausbaustufe
+
+### Konfiguration
+
+Clients finden den MatrixRTC-Dienst über `.well-known/matrix/client`. Dort wird der LiveKit-JWT-Dienst als `org.matrix.msc4143.rtc_foci` angekündigt. Diese Datei muss öffentlich lesbar sein, als JSON ausgeliefert werden und CORS für Webclients erlauben.
+
+Beispiel:
+
+```json
+{
+  "m.homeserver": {
+    "base_url": "https://matrix.example.com"
+  },
+  "org.matrix.msc4143.rtc_foci": [
+    {
+      "type": "livekit",
+      "livekit_service_url": "https://call.example.com/livekit/jwt"
+    }
+  ]
+}
+```
+
+## Authentifizierung und Nutzerverwaltung
+
+FEDEO sollte Identität und Lebenszyklus der Nutzer zentral steuern.
+
+### Empfohlener Ablauf
+
+1. Nutzer wird in FEDEO angelegt.
+2. FEDEO erzeugt oder aktualisiert den Matrix-Nutzer.
+3. FEDEO weist den Nutzer den passenden Spaces und Räumen zu.
+4. Login erfolgt über FEDEO SSO/OIDC.
+5. Deaktivierung in FEDEO deaktiviert auch den Matrix-Zugang und entfernt Raumzugriffe.
+
+Die Matrix User-ID sollte stabil und nicht personenbezogen änderungsanfällig sein:
+
+```text
+@u_<fedeo_user_id>:example.com
+```
+
+Der Anzeigename kann weiterhin den echten Namen enthalten und bei Änderungen synchronisiert werden.
+
+## Datenschutz und Compliance
+
+Matrix erlaubt starke Datenschutzkonzepte, erfordert aber klare Betriebsregeln.
+
+### Empfehlungen
+
+- Ende-zu-Ende-Verschlüsselung für Direktnachrichten und vertrauliche Projekträume aktivieren.
+- Nicht verschlüsselte Räume nur dort nutzen, wo serverseitige Suche, Archivierung oder Compliance-Funktionen ausdrücklich benötigt werden.
+- Medienaufbewahrung mandantenweit konfigurierbar machen.
+- Externe Gäste optisch klar kennzeichnen.
+- Federation standardmäßig deaktivieren oder auf erlaubte Domains beschränken.
+- Aufzeichnungen von Videokonferenzen nur mit expliziter Einwilligung und sichtbarem Status erlauben.
+- Administrative Zugriffe protokollieren.
+- Klare Löschfristen für Räume, Anhänge und Audit-Referenzen definieren.
+
+## Federation
+
+Matrix kann mit anderen Homeservern föderieren. Für FEDEO sollte Federation als kontrollierbare Option umgesetzt werden.
+
+### Betriebsmodi
+
+| Modus | Beschreibung | Empfehlung |
+| --- | --- | --- |
+| geschlossen | Keine Federation, nur interne Nutzer und explizite Gäste | Standard für kleine Installationen |
+| allowlist | Federation nur mit freigegebenen Domains | Empfehlung für B2B-Kommunikation |
+| offen | Federation mit beliebigen Matrix-Servern | Nur für bewusst öffentliche Communities |
+
+Für steuer-, kunden- und projektnahe Kommunikation ist `allowlist` der beste Zielmodus.
+
+## Brücken zu anderen Systemen
+
+Matrix unterstützt Brücken zu anderen Kommunikationsdiensten. Für FEDEO sind Brücken nützlich, sollten aber nicht zur ersten Produktstufe gehören.
+
+Mögliche spätere Erweiterungen:
+
+- E-Mail-Brücke für Helpdesk- oder Kundenkommunikation
+- Slack- oder Teams-Brücke für externe Projektpartner
+- WhatsApp- oder SMS-Brücke nur nach gesonderter Datenschutzprüfung
+- SIP-Brücke für Telefonie
+
+Brücken müssen pro Mandant aktivierbar sein und brauchen klare Hinweise, welche Daten an externe Dienste fließen.
+
+## FEDEO-Produktoberfläche
+
+Die Kommunikation sollte in FEDEO an zwei Stellen sichtbar sein.
+
+### Globaler Kommunikationsbereich
+
+- Raumliste
+- Direktnachrichten
+- Suche
+- Anrufe
+- laufende Besprechungen
+- Benachrichtigungen
+
+### Objektbezogene Kommunikation
+
+In Projekten, Kunden, Vorgängen, Helpdesk-Tickets und Dokumenten erscheint ein Kommunikations-Tab:
+
+- zugeordneter Raum
+- relevante Nachrichtenreferenzen
+- Start von Chat, Anruf oder Besprechung
+- Teilnehmerverwaltung entsprechend FEDEO-Rechten
+
+So bleibt Kommunikation dort, wo die Arbeit stattfindet.
+
+## Backend-Integration
+
+Das FEDEO-Backend erhält ein Kommunikationsmodul mit folgenden Aufgaben:
+
+- Matrix-Nutzer provisionieren
+- Spaces und Räume anlegen
+- Raum-Mitgliedschaften synchronisieren
+- Matrix-Event-Webhooks empfangen
+- FEDEO-Objekte mit Matrix-Räumen verknüpfen
+- Benachrichtigungseinstellungen verwalten
+- Admin-Aktionen auditieren
+
+Technisch kann dies über Matrix Admin API, Client-Server API und Application Services erfolgen. Für Automationen empfiehlt sich ein eigener Application Service, weil er reservierte Nutzer- und Raum-Namensräume sauber verwalten kann.
+
+## Deployment-Erweiterung
+
+Der bestehende Docker-/Traefik-Ansatz kann um folgende Dienste erweitert werden:
+
+- `matrix-synapse`
+- `matrix-db` oder gemeinsame PostgreSQL-Instanz mit getrennter Datenbank
+- `redis`
+- `coturn`
+- `element-web` optional als Fallback-Client
+- `element-call`
+- `livekit`
+- `matrix-rtc-jwt-service`
+
+Für produktive Installationen sollte Matrix eine eigene PostgreSQL-Datenbank erhalten. Medien sollten in S3-kompatiblen Speicher ausgelagert werden, damit große Anhänge und Konferenzartefakte nicht den Applikationsserver füllen.
+
+## Monitoring
+
+Wichtige Kennzahlen:
+
+- aktive Nutzerinnen und Nutzer
+- Anzahl Räume pro Mandant
+- Nachrichtenrate
+- Medien-Speicherverbrauch
+- Zustellverzögerung
+- fehlgeschlagene Anrufe
+- LiveKit Paketverlust, Latenz und Teilnehmerzahl
+- TURN-Nutzung
+- Federation-Fehler
+
+Logs von FEDEO, Synapse, LiveKit, coturn und Traefik sollten über eine gemeinsame Korrelation, zum Beispiel Request-ID oder Nutzer-ID, untersuchbar sein.
+
+## Risiken und Gegenmaßnahmen
+
+| Risiko | Gegenmaßnahme |
+| --- | --- |
+| Komplexität durch zwei Systeme | FEDEO bleibt führend für Nutzer, Rechte und Objektbezug |
+| Datenschutz bei externen Räumen | Externe Kennzeichnung, Federation-Allowlist, Mandantenrichtlinien |
+| E2EE erschwert Suche und Archivierung | Raumtyp bewusst wählen, lokale Suche, Metadatenreferenzen statt Vollkopie |
+| Medienverbindungen scheitern in Firmennetzen | coturn sauber betreiben, UDP und TCP/TLS-Fallback anbieten |
+| Betriebskosten durch Video | LiveKit skalierbar betreiben, Limits pro Mandant definieren |
+| Gästezugriff wird unübersichtlich | Einladungslinks mit Ablaufdatum, Wartebereich, Moderationsrechte |
+
+## Umsetzung in Phasen
+
+### Phase 1: Fundament und Chat
+
+- Synapse mit PostgreSQL, Redis, Traefik und `.well-known` betreiben
+- FEDEO-Nutzer zu Matrix synchronisieren
+- Mandanten-Spaces und erste Teamräume anlegen
+- Chat im FEDEO-Frontend integrieren
+- Benachrichtigungen und Raumreferenzen speichern
+
+### Phase 2: Objektbezogene Kommunikation
+
+- Räume automatisch für Projekte, Vorgänge und Kunden anlegen
+- Kommunikations-Tab in FEDEO-Objekten ergänzen
+- Rechteänderungen aus FEDEO nach Matrix synchronisieren
+- externe Gäste einladen und kennzeichnen
+
+### Phase 3: Audio und Video
+
+- coturn bereitstellen
+- MatrixRTC, Element Call und LiveKit integrieren
+- Anruf- und Videobuttons in Chat, Kontakten und Projekten ergänzen
+- Gäste-Links und Wartebereich umsetzen
+
+### Phase 4: Compliance und Skalierung
+
+- Aufbewahrungsrichtlinien pro Mandant
+- Monitoring und Admin-Dashboards
+- Federation-Allowlist
+- optionale Brücken
+- optionale Aufzeichnung mit Einwilligungsworkflow
+
+## Offene Entscheidungen
+
+- Soll Federation initial deaktiviert oder direkt mit Allowlist ausgeliefert werden?
+- Welche Räume müssen serverseitig durchsuchbar sein und bleiben deshalb unverschlüsselt?
+- Sollen externe Gäste Matrix-Konten erhalten oder nur temporäre Konferenzzugänge?
+- Wird Element als sichtbarer Fallback-Client angeboten oder soll alles primär in FEDEO stattfinden?
+- Welche Mandantenlimits gelten für Speicher, Teilnehmerzahl und Videodauer?

+# Telekom-Telefonie in FEDEO
+
+FEDEO kann den lokalen Asterisk-Stack als Übergang zur externen Telefonie nutzen. Die Telekom-Anbindung wird mandantenbezogen in FEDEO unter **Firmeneinstellungen -> Integrationen -> Telefonie-Trunk** gepflegt.
+
+## Zugangsdaten
+
+Für Telekom-SIP ist der Registrar normalerweise `tel.t-online.de`. Die SIP-ID ist in der Regel die Rufnummer mit Vorwahl ohne Leerzeichen und Sonderzeichen, zum Beispiel `0301234567`.
+
+Wenn dein Anschluss statt einer separaten SIP-ID die klassischen Zugangsdaten nutzt, kann der Authentifizierungsnutzer aus Anschlusskennung, Zugangsnummer, Mitbenutzernummer und `@t-online.de` gebildet werden:
+
+```env
+TELEPHONY_TELEKOM_AUTH_USER=<anschlusskennung><zugangsnummer>#<mitbenutzernummer>@t-online.de
+```
+
+## FEDEO Einstellungen
+
+Öffne **Firmeneinstellungen -> Integrationen** und fülle den Bereich **Telefonie-Trunk** aus:
+
+- `SIP-ID / Rufnummer`: Rufnummer mit Vorwahl ohne Leerzeichen und Sonderzeichen
+- `Kennwort`: persönliches Kennwort oder SIP-Kennwort
+- `Auth-User`: optional, falls dein Anschluss nicht direkt mit der SIP-ID authentifiziert
+- `Absendernummer`: optional, meist identisch zur SIP-ID
+- `Eingehende Nebenstelle`: lokale FEDEO/Asterisk-Nebenstelle, z. B. `1001`
+- `Ausgehender Prefix`: standardmäßig `0`
+- `Öffentliche Signaling-Adresse`: öffentliche IP oder DNS-Name, unter dem Asterisk von Telekom erreichbar ist
+- `Öffentliche Medien-Adresse`: öffentliche RTP-Adresse, leer nutzt die Signaling-Adresse
+- `Lokale Netze`: interne Netze, für die Asterisk keine öffentliche Adresse einsetzen soll
+
+Das Kennwort wird nicht wieder an das Frontend zurückgegeben. In der Oberfläche siehst du nur, ob ein Kennwort gespeichert ist.
+
+Nach dem Speichern muss die Konfiguration mit **In Asterisk anwenden** in die Asterisk-Include-Dateien geschrieben werden. FEDEO lädt danach PJSIP und den Dialplan über AMI neu und fordert die Telekom-Registration an. Den Laufzeitstatus findest du unter **Kommunikation -> Telefonie Setup** im Bereich **Externe Telefonie**.
+
+Wenn du die öffentliche Signaling- oder Medien-Adresse änderst, muss Asterisk anschließend neu gestartet werden, weil PJSIP-Transporte diese Werte nicht vollständig im laufenden Betrieb neu laden.
+
+## `.env` Fallback
+
+Die `.env`-Werte bleiben nur als lokaler Fallback für den Asterisk-Teststack erhalten, falls keine mandantenbezogene Konfiguration gepflegt ist.
+
+```env
+TELEPHONY_ENABLED=true
+TELEPHONY_EXTERNAL_PROVIDER=telekom
+TELEPHONY_EXTERNAL_ENABLED=true
+
+TELEPHONY_TELEKOM_ENABLED=true
+TELEPHONY_TELEKOM_REGISTRAR=tel.t-online.de
+TELEPHONY_TELEKOM_SIP_USER=<rufnummer_mit_vorwahl_ohne_sonderzeichen>
+TELEPHONY_TELEKOM_AUTH_USER=
+TELEPHONY_TELEKOM_PASSWORD=<persönliches_kennwort_oder_sip_kennwort>
+TELEPHONY_TELEKOM_CALLER_ID=<rufnummer_mit_vorwahl_ohne_sonderzeichen>
+TELEPHONY_TELEKOM_INBOUND_EXTENSION=1001
+TELEPHONY_TELEKOM_OUTBOUND_PREFIX=0
+TELEPHONY_ASTERISK_GENERATED_DIR=/var/lib/fedeo/asterisk/generated
+TELEPHONY_ASTERISK_AMI_HOST=asterisk-dev
+TELEPHONY_ASTERISK_AMI_PORT=5038
+TELEPHONY_ASTERISK_AMI_USER=fedeo
+TELEPHONY_ASTERISK_AMI_PASSWORD=fedeo-ami-dev
+```
+
+Wenn das Backend lokal auf dem Host läuft, muss es AMI über `127.0.0.1:5038` erreichen. Der Entwicklungsstack mappt dafür `TELEPHONY_DEV_AMI_PORT` auf den Asterisk-Container.
+
+Wenn `TELEPHONY_TELEKOM_AUTH_USER` leer bleibt, verwendet Asterisk automatisch `TELEPHONY_TELEKOM_SIP_USER` als Authentifizierungsnutzer.
+
+## Start
+
+```bash
+docker compose --profile telephony-dev up -d asterisk-dev
+```
+
+Beim Start erzeugt der Container die Dateien `pjsip.telekom.conf` und `extensions.telekom.conf` in einem Docker-Volume. Ausgehende Anrufe mit Prefix `0` und internationale Ziele mit `+` werden über den Telekom-Trunk geroutet. Eingehende Anrufe landen standardmäßig auf Nebenstelle `1001`.
+
+## FreePBX als Diagnose-PBX
+
+Für Provider-Tests kann zusätzlich das optionale Profil `freepbx-dev` gestartet werden. FreePBX ist hier nicht als dauerhafte FEDEO-Abhängigkeit gedacht, sondern als Referenzoberfläche, um Trunk-, NAT-, CLIP- und Routing-Parameter gegen einen Provider wie Easybell zu prüfen.
+
+```bash
+docker compose --profile freepbx-dev up -d freepbx-dev-db freepbx-dev
+```
+
+Beim ersten Start muss FreePBX einmal gegen die lokale MariaDB installiert werden:
+

+  bash -lc 'php install -n --dbuser=freepbxuser --dbpass="$(cat /run/secrets/freepbx_user_password)" --dbhost=freepbx-dev-db'
+```
+
+Danach ist die Oberfläche lokal unter `http://localhost:18080` erreichbar. Beim ersten Öffnen zeigt FreePBX die Ersteinrichtung für den Web-Admin-Benutzer. Diese Zugangsdaten gelten nur für die FreePBX-Diagnoseoberfläche und sind unabhängig von FEDEO.
+
+Die Standardports sind bewusst konfliktarm gesetzt:
+
+- Web: `18080` / `18443`
+- SIP UDP: `15060`
+- RTP UDP: `18000-18100`
+
+Das verwendete FreePBX-Image ist aktuell nur für `linux/amd64` veröffentlicht. Auf Apple-Silicon-Hosts nutzt Docker Desktop deshalb über `FREEPBX_DEV_PLATFORM=linux/amd64` Emulation; für Diagnosezwecke ist das ausreichend, aber nicht als Produktionssetup gedacht.
+
+Für einen möglichst realistischen Easybell-Test kann der FEDEO-Asterisk kurz gestoppt und FreePBX auf dem üblichen SIP-Port gestartet werden:
+
+```bash
+docker compose --profile telephony-dev stop asterisk-dev
+FREEPBX_DEV_SIP_PORT=5060 docker compose --profile freepbx-dev up -d freepbx-dev
+```
+
+In FreePBX sollte der RTP-Bereich unter **Settings -> Asterisk SIP Settings** ebenfalls auf `18000-18100` gesetzt werden, damit er zur Compose-Portfreigabe passt. Wenn der Trunk dort erfolgreich registriert und ein Testanruf möglich ist, können die funktionierenden PJSIP- und NAT-Werte nach FEDEO übernommen werden.

+# Telekom-Telefonie in FEDEO
+
+FEDEO kann den lokalen Asterisk-Stack als Übergang zur externen Telefonie nutzen. Die Telekom-Anbindung wird mandantenbezogen in FEDEO unter **Firmeneinstellungen -> Integrationen -> Telefonie-Trunk** gepflegt.
+
+## Zugangsdaten
+
+Für Telekom-SIP ist der Registrar normalerweise `tel.t-online.de`. Die SIP-ID ist in der Regel die Rufnummer mit Vorwahl ohne Leerzeichen und Sonderzeichen, zum Beispiel `0301234567`.
+
+Wenn dein Anschluss statt einer separaten SIP-ID die klassischen Zugangsdaten nutzt, kann der Authentifizierungsnutzer aus Anschlusskennung, Zugangsnummer, Mitbenutzernummer und `@t-online.de` gebildet werden:
+
+```env
+TELEPHONY_TELEKOM_AUTH_USER=<anschlusskennung><zugangsnummer>#<mitbenutzernummer>@t-online.de
+```
+
+## FEDEO Einstellungen
+
+Öffne **Firmeneinstellungen -> Integrationen** und fülle den Bereich **Telefonie-Trunk** aus:
+
+- `SIP-ID / Rufnummer`: Rufnummer mit Vorwahl ohne Leerzeichen und Sonderzeichen
+- `Kennwort`: persönliches Kennwort oder SIP-Kennwort
+- `Auth-User`: optional, falls dein Anschluss nicht direkt mit der SIP-ID authentifiziert
+- `Absendernummer`: optional, meist identisch zur SIP-ID
+- `Eingehende Nebenstelle`: lokale FEDEO/Asterisk-Nebenstelle, z. B. `1001`
+- `Ausgehender Prefix`: standardmäßig `0`
+- `Öffentliche Signaling-Adresse`: öffentliche IP oder DNS-Name, unter dem Asterisk von Telekom erreichbar ist
+- `Öffentliche Medien-Adresse`: öffentliche RTP-Adresse, leer nutzt die Signaling-Adresse
+- `Lokale Netze`: interne Netze, für die Asterisk keine öffentliche Adresse einsetzen soll
+
+Das Kennwort wird nicht wieder an das Frontend zurückgegeben. In der Oberfläche siehst du nur, ob ein Kennwort gespeichert ist.
+
+Nach dem Speichern muss die Konfiguration mit **In Asterisk anwenden** in die Asterisk-Include-Dateien geschrieben werden. FEDEO lädt danach PJSIP und den Dialplan über AMI neu und fordert die Telekom-Registration an. Den Laufzeitstatus findest du unter **Kommunikation -> Telefonie Setup** im Bereich **Externe Telefonie**.
+
+Wenn du die öffentliche Signaling- oder Medien-Adresse änderst, muss Asterisk anschließend neu gestartet werden, weil PJSIP-Transporte diese Werte nicht vollständig im laufenden Betrieb neu laden.
+
+## `.env` Fallback
+
+Die `.env`-Werte bleiben nur als lokaler Fallback für den Asterisk-Teststack erhalten, falls keine mandantenbezogene Konfiguration gepflegt ist.
+
+```env
+TELEPHONY_ENABLED=true
+TELEPHONY_EXTERNAL_PROVIDER=telekom
+TELEPHONY_EXTERNAL_ENABLED=true
+
+TELEPHONY_TELEKOM_ENABLED=true
+TELEPHONY_TELEKOM_REGISTRAR=tel.t-online.de
+TELEPHONY_TELEKOM_SIP_USER=<rufnummer_mit_vorwahl_ohne_sonderzeichen>
+TELEPHONY_TELEKOM_AUTH_USER=
+TELEPHONY_TELEKOM_PASSWORD=<persönliches_kennwort_oder_sip_kennwort>
+TELEPHONY_TELEKOM_CALLER_ID=<rufnummer_mit_vorwahl_ohne_sonderzeichen>
+TELEPHONY_TELEKOM_INBOUND_EXTENSION=1001
+TELEPHONY_TELEKOM_OUTBOUND_PREFIX=0
+TELEPHONY_ASTERISK_GENERATED_DIR=/var/lib/fedeo/asterisk/generated
+TELEPHONY_ASTERISK_AMI_HOST=asterisk-dev
+TELEPHONY_ASTERISK_AMI_PORT=5038
+TELEPHONY_ASTERISK_AMI_USER=fedeo
+TELEPHONY_ASTERISK_AMI_PASSWORD=fedeo-ami-dev
+```
+
+Wenn das Backend lokal auf dem Host läuft, muss es AMI über `127.0.0.1:5038` erreichen. Der Entwicklungsstack mappt dafür `TELEPHONY_DEV_AMI_PORT` auf den Asterisk-Container.
+
+Wenn `TELEPHONY_TELEKOM_AUTH_USER` leer bleibt, verwendet Asterisk automatisch `TELEPHONY_TELEKOM_SIP_USER` als Authentifizierungsnutzer.
+
+## Start
+
+```bash
+docker compose --profile telephony-dev up -d asterisk-dev
+```
+
+Beim Start erzeugt der Container die Dateien `pjsip.telekom.conf`, `extensions.telekom.conf` und `pjsip.webrtc.conf` in einem Docker-Volume. Ausgehende Anrufe mit Prefix `0` und internationale Ziele mit `+` werden über den Trunk geroutet. Eingehende Anrufe landen standardmäßig auf Nebenstelle `1001`; die konfigurierte Rufnummer wird zusätzlich als DID direkt geroutet.
+
+Wenn Asterisk auf einem VPS oder hinter NAT läuft, sollten `TELEPHONY_ASTERISK_EXTERNAL_SIGNALING_ADDRESS` und `TELEPHONY_ASTERISK_EXTERNAL_MEDIA_ADDRESS` auf die öffentliche Asterisk-Adresse gesetzt werden. FEDEO schreibt daraus die WebRTC-Media-Adresse, damit Browser-Clients den RTP/ICE-Pfad sauber aushandeln.

+# Zentraler Push-Server für FEDEO
+
+Dieser Entwurf beschreibt einen zentral betriebenen FEDEO-Push-Server, über den selbst gehostete FEDEO-Instanzen Push Notifications zustellen können. Ziel ist, dass Selfhost-Betreiber keine eigenen Apple-, Google- oder Web-Push-Zugangsdaten verwalten müssen und FEDEO trotzdem mandantenfähig, datensparsam und zuverlässig benachrichtigen kann.
+
+## Zielbild
+
+FEDEO erhält einen zentralen Zustelldienst unter einer FEDEO-kontrollierten Domain, zum Beispiel `https://push.fedeo.cloud`. Jede selbst gehostete Instanz registriert sich dort einmalig als Push-Client. Danach sendet die Instanz nur noch neutrale Zustellaufträge an den zentralen Server. Der zentrale Server übernimmt:
+
+- Verwaltung öffentlicher Push-Konfigurationen für Web, iOS und Android
+- Annahme signierter Zustellaufträge von Selfhost-Instanzen
+- Zustellung über Web Push, APNs und FCM
+- Retry, Rate Limits, Fehlerklassifizierung und Deaktivierung ungültiger Geräte
+- technische Zustellmetriken ohne fachliche Inhaltsdaten
+
+Die fachliche Entscheidung, wer welche Benachrichtigung erhält, bleibt in der jeweiligen FEDEO-Instanz. Der zentrale Server ist nur Transport- und Zustellkomponente.
+
+## Grundprinzipien
+
+- **Datenminimierung:** Der zentrale Server speichert keine FEDEO-Nutzerdaten, keine Mandantendaten und möglichst keine lesbaren Nachrichtentexte.
+- **Instanzhoheit:** Selfhost-Instanzen behalten Nutzerverwaltung, Benachrichtigungseinstellungen und Eventlogik.
+- **Zentrale Provider-Schlüssel:** APNs-, FCM- und VAPID-Schlüssel liegen ausschließlich im zentralen Push-Server.
+- **Signierte Aufträge:** Jede Instanz authentifiziert sich per rotierbarem Instanzschlüssel.
+- **Mandantentrennung:** Instanzen und deren Geräte werden strikt getrennt, auch wenn sie denselben zentralen Dienst nutzen.
+- **Ausfallsicherheit:** Der lokale FEDEO-Betrieb darf nicht blockieren, wenn der Push-Server temporär nicht erreichbar ist.
+
+## Architektur
+
+```text
+FEDEO Web / Mobile App
+  |
+  | registriert Gerät bei lokaler Selfhost-Instanz
+  v
+Selfhost-FEDEO-Instanz

+  +--> Firebase Cloud Messaging
+```
+
+### Komponenten
+
+| Komponente | Aufgabe |
+| --- | --- |
+| Selfhost-FEDEO-Backend | entscheidet Empfänger, erzeugt Notification Items, übermittelt Push-Aufträge |
+| Zentrale Push API | registriert Instanzen und Geräte, nimmt Push-Aufträge an |
+| Push Worker | sendet an Web Push, APNs und FCM, verarbeitet Provider-Fehler |
+| Geräte-Registry | speichert technische Push Tokens oder Web-Push-Subscriptions |
+| Zustelljournal | speichert technische Statuswerte, keine fachliche Historie |
+| Admin-Konsole | zeigt Instanzstatus, Fehlerquoten, Rate Limits und Schlüsselrotation |
+
+## Rollenverteilung
+
+### Lokale FEDEO-Instanz
+
+Die Selfhost-Instanz bleibt führend für:
+
+- Nutzer und Mandanten
+- Benachrichtigungseinstellungen
+- Event-Typen und Kanäle
+- fachliche Nachrichtentexte
+- In-App-Benachrichtigungen
+- lokale Audit- und Lesestatusdaten
+
+Sie speichert weiterhin `notifications_items` und entscheidet, ob für ein Ereignis der Kanal `push` aktiv ist. Statt selbst über `web-push` zu senden, ruft sie den zentralen Push-Server auf.
+
+### Zentraler Push-Server
+
+Der zentrale Server ist zuständig für:
+
+- öffentliche Push-Konfiguration für Clients
+- Entgegennahme von Geräte-Registrierungen
+- Mapping von lokalen Geräte-IDs auf Provider Tokens
+- Zustellung an externe Push-Netze
+- technische Fehlerbehandlung
+- Missbrauchsschutz, Quotas und Sperren
+
+Er kennt keine FEDEO-Berechtigungen. Wenn eine lokale Instanz einen gültig signierten Push-Auftrag sendet, wird dieser technisch zugestellt.
+
+## Datenschutzmodell
+
+Für die erste Ausbaustufe sollte der Push-Server Push-Inhalte nur transitär verarbeiten und nicht dauerhaft speichern. Dauerhaft gespeichert werden:
+
+- Instanz-ID
+- Geräte-ID
+- Plattform: `web`, `ios`, `android`
+- Provider-Endpunkt oder Provider-Token, verschlüsselt gespeichert
+- Zeitpunkte: erstellt, zuletzt gesehen, deaktiviert
+- Zustellstatus pro Auftrag: angenommen, gesendet, fehlgeschlagen
+- technische Fehlercodes
+
+Nicht dauerhaft gespeichert werden:
+
+- Name, E-Mail oder lokale Nutzer-ID
+- Mandantenname
+- fachliche Objekt-IDs, sofern nicht zwingend notwendig
+- vollständige Nachrichtentexte
+
+Für Benachrichtigungen mit sensiblen Inhalten empfiehlt sich ein Payload-Modell mit generischem Text:
+
+```json
+{
+  "title": "Neue FEDEO-Benachrichtigung",
+  "body": "Öffne FEDEO, um die Details anzusehen.",
+  "data": {
+    "notificationId": "lokale-notification-id",
+    "instanceBaseUrl": "https://app.example.com"
+  }
+}
+```
+
+Die lokale App lädt Details anschließend authentifiziert von der Selfhost-Instanz.
+
+## Instanzregistrierung
+
+Jede Selfhost-Instanz erhält beim Setup eine zentrale Instanzidentität.
+
+### Ablauf
+
+1. Betreiber öffnet in FEDEO den Bereich `Administration > Push Notifications`.
+2. FEDEO erzeugt eine lokale Instanz-ID, falls noch keine existiert.
+3. Betreiber meldet die Instanz am zentralen Push-Portal an oder nutzt einen geführten Aktivierungscode.
+4. Der zentrale Server erzeugt einen Client-Schlüssel.
+5. Die Selfhost-Instanz speichert `FEDEO_PUSH_INSTANCE_ID` und `FEDEO_PUSH_CLIENT_SECRET`.
+6. Die Instanz ruft regelmäßig einen Healthcheck auf.
+
+### Benötigte Umgebungsvariablen
+
+```env
+FEDEO_PUSH_MODE=central
+FEDEO_PUSH_GATEWAY_URL=https://push.fedeo.cloud
+FEDEO_PUSH_INSTANCE_ID=inst_...
+FEDEO_PUSH_CLIENT_SECRET=...
+FEDEO_PUSH_PAYLOAD_MODE=minimal
+```
+
+`FEDEO_PUSH_MODE=local` bleibt für Entwickler und Betreiber möglich, die eigene VAPID-Schlüssel nutzen möchten.
+
+## Geräte-Registrierung
+
+Die lokale FEDEO-Instanz sollte weiterhin der erste Ansprechpartner für den Client bleiben. Dadurch kann sie Authentifizierung und Mandantenzuordnung prüfen.
+
+### Web Push
+
+1. FEDEO Web fragt lokal `/api/notifications/push/config` ab.
+2. Die lokale Instanz liefert bei `central` die öffentliche VAPID-Konfiguration des zentralen Servers.
+3. Der Browser erzeugt eine Web-Push-Subscription.
+4. FEDEO Web sendet die Subscription an die lokale Instanz.
+5. Die lokale Instanz registriert die Subscription beim zentralen Push-Server.
+6. Der zentrale Server gibt eine `centralDeviceId` zurück.
+7. Die lokale Instanz speichert diese ID in `notification_push_subscriptions.meta`.
+
+### Mobile Push
+
+Für iOS und Android registriert die FEDEO-App das Gerät über die native Push-Schicht und sendet den Provider Token an die lokale Instanz. Die lokale Instanz leitet ihn an den zentralen Push-Server weiter. Der zentrale Server speichert den Token verschlüsselt und liefert eine `centralDeviceId` zurück.
+
+## API-Entwurf
+
+Alle Instanz-API-Aufrufe nutzen HTTPS und eine HMAC-Signatur oder kurze JWTs mit rotierbarem Secret.
+
+### `GET /v1/public-config`
+
+Liefert öffentliche Push-Parameter.
+
+```json
+{
+  "webPushPublicKey": "...",
+  "iosBundleId": "cloud.fedeo.app",
+  "androidSenderId": "..."

+
+Antwort:
+
+```json
+{
+  "accepted": 1,
+  "rejected": 0,
+  "deliveryJobId": "job_abc"
+}
+```
+
+### `GET /v1/push/{deliveryJobId}`
+
+Liefert technische Zustellinformationen für Debugging und Support.
+
+```json
+{
+  "status": "completed",
+  "sent": 1,
+  "failed": 0,
+  "disabledDevices": []
+}
+```
+
+## Lokale Backend-Anpassung
+
+Der bestehende `NotificationService` kann um einen Provider ergänzt werden:
+
+```text
+NotificationService
+  |
+  +-- InAppDeliveryProvider
+  +-- EmailDeliveryProvider
+  +-- LocalWebPushDeliveryProvider
+  +-- CentralPushDeliveryProvider
+```
+
+`CentralPushDeliveryProvider` nutzt die lokalen Einträge aus `notification_push_subscriptions`, sucht aktive Geräte mit `centralDeviceId` und sendet Zustellaufträge an den zentralen Push-Server. Ohne `centralDeviceId` versucht er eine Nachregistrierung oder markiert den lokalen Eintrag als fehlerhaft.
+
+Für Kompatibilität sollte die lokale Tabelle erweitert oder die vorhandene `meta`-Spalte genutzt werden:
+
+```json
+{
+  "centralDeviceId": "dev_789",
+  "platform": "web",
+  "registeredVia": "central",
+  "lastGatewaySyncAt": "2026-05-22T10:00:00Z"
+}
+```
+
+## Zustellverhalten
+
+### Idempotenz
+
+Jede lokale Instanz sendet pro Notification Item und Gerät einen stabilen `idempotencyKey`. Der zentrale Server verarbeitet denselben Key innerhalb eines konfigurierbaren Fensters nur einmal.
+
+### Retry
+
+Der zentrale Server unterscheidet:
+
+- temporäre Fehler: Netzwerk, Provider-Timeout, Rate Limit
+- dauerhafte Fehler: ungültiges Token, abgelaufene Web-Push-Subscription
+- Konfigurationsfehler: gesperrte Instanz, ungültige Signatur, Quota überschritten
+
+Temporäre Fehler werden mit exponentiellem Backoff wiederholt. Dauerhafte Gerätefehler deaktivieren das zentrale Gerät und werden an die lokale Instanz zurückgemeldet.
+
+### Rückmeldung an lokale Instanzen
+
+Für die erste Ausbaustufe reicht Pull-basiertes Debugging über `GET /v1/push/{deliveryJobId}`. Später kann ein Webhook ergänzt werden:
+
+```text
+POST <selfhost-base-url>/api/notifications/push/gateway-callback
+```
+
+Damit kann die lokale Instanz ungültige Geräte automatisch deaktivieren.
+
+## Sicherheit
+
+### Authentifizierung
+
+Empfohlen ist ein HMAC-Schema:
+
+```text
+X-Fedeo-Instance-Id: inst_123
+X-Fedeo-Timestamp: 2026-05-22T10:00:00Z
+X-Fedeo-Signature: hmac-sha256(...)
+```
+
+Signiert werden Methode, Pfad, Timestamp, Body-Hash und Instanz-ID. Requests mit zu altem Timestamp werden abgelehnt.
+
+### Secret-Rotation
+
+Der zentrale Server sollte pro Instanz zwei aktive Secrets unterstützen:
+
+- `currentSecret`
+- `nextSecret`
+
+Die Selfhost-Instanz kann dadurch ohne Ausfall rotieren. Nach erfolgreichem Wechsel wird das alte Secret deaktiviert.
+
+### Missbrauchsschutz
+
+- Rate Limit pro Instanz
+- Tageskontingent pro Instanz
+- Maximalgröße für Payloads
+- Blocklist für kompromittierte Instanzen
+- Audit-Log für Admin-Aktionen
+- strikte Validierung von Links, damit Pushes nicht zu fremden Domains leiten
+
+## Betriebsmodell
+
+### Deployment
+
+Der zentrale Push-Server sollte als eigener Dienst betrieben werden:
+
+- `push-api`: HTTP API für Instanzen und Admin-Konsole
+- `push-worker`: Queue-Verarbeitung und Provider-Zustellung
+- `postgres`: Instanzen, Geräte, Jobs, Audit
+- `redis`: Queue, Rate Limits, kurzlebige Idempotenzdaten
+- `traefik` oder anderer Reverse Proxy mit TLS
+
+### Monitoring
+
+Wichtige Metriken:
+
+- angenommene Push-Aufträge pro Instanz
+- Zustellquote pro Plattform
+- Provider-Latenz
+- Fehlerrate nach Fehlerklasse
+- deaktivierte Geräte
+- Queue-Länge und Retry-Alter
+- Signaturfehler und Rate-Limit-Treffer
+
+### Verfügbarkeit
+
+Wenn der zentrale Push-Server nicht erreichbar ist, markiert die lokale Instanz Push-Zustellungen als temporär fehlgeschlagen und versucht sie später erneut. In-App-Benachrichtigungen bleiben davon unberührt.
+
+## Migrationspfad
+
+### Phase 1: Web Push Gateway
+
+- zentrale VAPID-Schlüssel bereitstellen
+- Selfhost-Instanzen gegen Push-Server authentifizieren
+- Web-Push-Subscriptions zentral registrieren
+- bestehendes lokales Web-Push-Sending optional durch Gateway ersetzen
+- minimale Payloads verwenden
+
+### Phase 2: Mobile Push
+
+- iOS und Android Tokens registrieren
+- APNs und FCM im zentralen Worker anbinden
+- Deep Links zur passenden Selfhost-Instanz öffnen
+- Token-Rotation und App-Neuinstallation robust behandeln
+
+### Phase 3: Rückmeldungen und Admin
+
+- Zustellcallbacks an Selfhost-Instanzen
+- Admin-Konsole für Instanzen, Sperren, Quotas und Fehleranalyse
+- Secret-Rotation per Oberfläche
+- Export technischer Logs für Supportfälle
+
+### Phase 4: Erweiterte Kanäle
+
+- mandantenweite Push-Richtlinien
+- gebündelte Pushes
+- stille Pushes für Synchronisation
+- optional Webhook-Zustellung für Integrationen
+
+## Offene Entscheidungen
+
+- Sollen Push-Inhalte standardmäßig immer minimal sein oder darf eine Instanz explizit lesbare Titel und Texte erlauben?
+- Wird die Instanzregistrierung über ein zentrales FEDEO-Konto oder über offline erzeugte Aktivierungscodes erfolgen?
+- Soll der zentrale Push-Server Bestandteil eines größeren FEDEO-Cloud-Portals werden?
+- Wie lange sollen technische Zustelllogs maximal aufbewahrt werden?
+- Welche Quotas gelten für kostenlose, lizenzierte und interne Instanzen?
+
+## Empfehlung für den ersten Schnitt
+
+Für den ersten produktionsnahen Stand sollte FEDEO nur Web Push über den zentralen Server abwickeln. Das passt direkt zum vorhandenen Benachrichtigungssystem und reduziert den Betreiberaufwand für Selfhost-Instanzen deutlich. Die lokale Instanz bleibt fachlich führend, der zentrale Server sieht nur technische Geräte und minimale Zustellaufträge.
+
+Die wichtigste Architekturentscheidung ist dabei, den zentralen Server nicht als Benachrichtigungslogik zu bauen, sondern als schlanken Push-Transport. Dadurch bleibt Selfhosting souverän, während FEDEO trotzdem die komplizierten Provider-Schlüssel und mobilen Push-Integrationen zentral beherrschen kann.
