+
+## Git und Commit-Nachrichten
+
+- Neue Projektdateien immer gezielt mit `git add` aufnehmen.
+- Nach einem abgeschlossenen Arbeitsschritt die eigenen Änderungen committen. Bereits vorhandene Änderungen anderer Aufgaben nicht mitcommitten oder zurücksetzen.
+- Jede selbst verfasste Commit-Nachricht muss Conventional Commits verwenden: `type(scope): Beschreibung`. Der Scope ist optional.
+- `fix:` für Fehlerkorrekturen (Patch), `feat:` für neue Funktionen (Minor), `perf:` für Leistungsverbesserungen (Patch).
+- `docs:`, `test:`, `refactor:`, `build:`, `ci:`, `chore:`, `style:` und `revert:` passend verwenden. Reine Wartungsänderungen lösen standardmäßig kein Release aus; Reverts können einen Patch auslösen.
+- Inkompatible Änderungen mit `!` im Betreff und einem Footer `BREAKING CHANGE: Beschreibung und Migrationshinweis` markieren (Major). Diese Kennzeichnung niemals weglassen, um einen Versionssprung zu vermeiden.
+- Beispiele: `fix(accounting): validate invoice totals`, `feat(stock): add inventory transfers`, `feat(api)!: replace legacy authentication`.
+- Auch selbst verfasste Squash- und Merge-Betreffzeilen entsprechend benennen. Die Release-Auswertung liest die ursprünglichen Commits und überspringt echte Merge-Commits.
+
+## Releases
+
+- `dev` ist der Entwicklungszweig. Ein Push auf `main` ist der vom Benutzer gewählte Release-Auslöser; der Gitea-Workflow prüft, baut und veröffentlicht automatisch.
+- Änderungen regulär auf dem aktuellen Entwicklungszweig committen. Erst bei einem ausdrücklichen Release-/Merge-/Push-Auftrag nach `main` übernehmen und pushen.
+- Versionsnummern werden aus den Git-Tags `vMAJOR.MINOR.PATCH` und den Commit-Nachrichten berechnet. Keine manuellen Release-Commits oder Änderungen an Paketversionen für Backend/Frontend erzeugen.
+- Vor Release-Arbeiten `docs/releases.md` lesen. Vorschau: `npm ci && npm run release:preview`. Prüfungen: `npm test && npm run commits:check`.
+- Veröffentlichte Versions-Tags und Images niemals überschreiben oder löschen. Einen fehlgeschlagenen Release anhand der dokumentierten Wiederaufnahme fortsetzen.
+- Mobile-App und Device-Agent behalten eigene Paketversionen; ihr Stand wird im Release-Manifest dokumentiert. App-Store-Veröffentlichungen haben einen eigenen Auslöser.

+# FEDEO Versionshistorie
+
+Die Release-Pipeline erzeugt die Versionshistorie automatisch aus Conventional Commits.
+
+- [Alle veröffentlichten Releases mit Änderungslisten](https://git.federspiel.tech/flfeders/FEDEO/releases)
+- Jeder Release enthält seine Änderungen zusätzlich als herunterladbare `CHANGELOG.md`.
+- `release-manifest.json` ordnet Version, Commit, Docker-Digests, Komponenten und Migrationen eindeutig zu.
+
+Die Versionshistorie vor Einführung der Releases bleibt in der Git-Historie erhalten. Die automatische Reihe beginnt mit `v3.0.0`; Ausgangspunkt ist der in `release.config.json` dokumentierte Commit.
+
+Die Pipeline schreibt keine automatischen Changelog-Commits zurück nach `main`. Dadurch bleiben Merge-Historie und Release-Auslöser eindeutig.

-TEST
+# FEDEO Hosting Guide
+
+Diese Anleitung beschreibt ein produktionsnahes Self-Hosting von FEDEO mit Docker Compose, Traefik, PostgreSQL und optionalem S3-kompatiblem Objektspeicher via MinIO.
+
+## Versionen und Releases
+
+Ein Push auf `main` veröffentlicht nach erfolgreichen Prüfungen und Builds automatisch die nächste FEDEO-Version. Die Versionsnummer und Release Notes entstehen aus Conventional Commits (`fix:`, `feat:`, Breaking Changes). `dev` bleibt der Entwicklungskanal.
+
+Für feste Selfhost-Versionen `FEDEO_VERSION` in `.env` auf eine veröffentlichte Version wie `3.0.0` setzen und die Betriebsdateien aus demselben Release verwenden. Ohne gesetzte Version bleibt der bisherige `dev`-Kanal aktiv. Die folgenden `raw/branch/dev`-Beispiele beschreiben diesen Entwicklungskanal.
+
+Release-Freigabe, Einrichtung der CI-Tokens, versionierte Installation, Updates und Wiederaufnahme sind unter [Versionierung und Releases](docs/releases.md) beschrieben. Die laufende Backend-Version liefert `/backend/version`; im Frontend steht sie unten in der Seitenleiste.
+
+## Architektur
+
+Der Stack besteht aus:
+
+- `frontend`: Nuxt-Frontend auf Port `3000`
+- `backend`: Node/Fastify-API auf Port `3100`
+- `db`: PostgreSQL
+- `traefik`: Reverse Proxy mit automatischen Let's-Encrypt-Zertifikaten
+- optional `minio`: S3-kompatibler Objektspeicher fur Dateiuploads
+
+Die Konfiguration erfolgt uber Umgebungsvariablen beziehungsweise eine `.env`-Datei im Deploy-Verzeichnis.
+
+## Voraussetzungen
+
+Vor dem Deployment sollten folgende Punkte erfullt sein:
+
+- Ein Linux-Server oder VPS mit offentlichen Ports `80` und `443`
+- Docker Engine inkl. Compose Plugin
+- Eine Domain, die auf den Server zeigt, z. B. `app.example.com`
+- Optional: SMTP-Zugang fur E-Mails
+- Optional: S3-Bucket oder MinIO fur Dateispeicher
+
+Empfohlen:
+
+- mindestens 2 vCPU
+- mindestens 4 GB RAM
+- SSD-Speicher fur PostgreSQL und Dateiuploads
+
+## DNS und Netzwerk
+
+Lege mindestens einen A- oder AAAA-Record an:
+
+- `app.example.com -> <SERVER-IP>`
+
+Traefik terminiert TLS direkt im Compose-Stack. Es ist kein zusatzlicher Reverse Proxy davor erforderlich.
+
+## Benotigte Backend-Umgebungsvariablen
+
+Das Backend erwartet mindestens diese Umgebungsvariablen:
+
+- `COOKIE_SECRET`
+- `JWT_SECRET`
+- `PORT`
+- `HOST`
+- `DATABASE_URL`
+- `S3_BUCKET`
+- `ENCRYPTION_KEY`
+- `MAILER_SMTP_HOST`
+- `MAILER_SMTP_PORT`
+- `MAILER_SMTP_SSL`
+- `MAILER_SMTP_USER`
+- `MAILER_SMTP_PASS`
+- `MAILER_FROM`
+- `S3_ENDPOINT`
+- `S3_REGION`
+- `S3_ACCESS_KEY`
+- `S3_SECRET_KEY`
+- `M2M_API_KEY`
+- `API_BASE_URL`
+- `GOCARDLESS_BASE_URL`
+- `GOCARDLESS_SECRET_ID`
+- `GOCARDLESS_SECRET_KEY`
+- `DOKUBOX_IMAP_HOST`
+- `DOKUBOX_IMAP_PORT`
+- `DOKUBOX_IMAP_SECURE`
+- `DOKUBOX_IMAP_USER`
+- `DOKUBOX_IMAP_PASSWORD`
+- `OPENAI_API_KEY`
+- `STIRLING_API_KEY`
+
+Minimal wichtige Werte fur den ersten Start:
+
+- `HOST=0.0.0.0`
+- `PORT=3100`
+- `DATABASE_URL=postgres://fedeo:<starkes-passwort>@db:5432/fedeo`
+- `API_BASE_URL=https://app.example.com/backend`
+
+Die Chat-Föderation verwendet ebenfalls `API_BASE_URL`; Gastlinks übernehmen deren Ursprung. Mit gültiger öffentlicher HTTPS-Adresse auf Port 443 und vorhandenem gültigem `ENCRYPTION_KEY` ist sie automatisch verfügbar. Zusätzliche URLs sind nur bei abweichender Infrastruktur nötig (`FEDEO_FEDERATION_URL`, `FEDEO_PUBLIC_URL`). `FEDEO_FEDERATION_ENABLED=false` schaltet sie ausdrücklich ab; der Standard ist `auto`. Der Updater übernimmt die passenden Compose-Einträge aus dem Release. Partner müssen anschließend weiterhin je Mandant freigegeben werden; siehe [Föderation einrichten](docs/chat-foederation-konzept.md#15-implementierter-stand-und-pilotbetrieb).
+
+Wenn du MinIO verwendest, setze zusatzlich:
+
+- `S3_ENDPOINT=http://minio:9000`
+- `S3_REGION=eu-central-1`
+- `S3_ACCESS_KEY=<MINIO_ROOT_USER>`
+- `S3_SECRET_KEY=<MINIO_ROOT_PASSWORD>`
+- `S3_BUCKET=fedeo`
+
+## Deploy-Struktur
+
+Deploye den Stack in einem eigenen Betriebsverzeichnis. Der Selfhost-Installer lädt dafür nur die benötigten Betriebsdateien und klont nicht das komplette Repository.
+
+Beispiel für die manuelle Vorbereitung:
+
+```bash
+mkdir -p /opt/fedeo/scripts
+curl -fsSL https://git.federspiel.tech/flfeders/FEDEO/raw/branch/dev/docker-compose.selfhost.yml -o /opt/fedeo/docker-compose.yml
+curl -fsSL https://git.federspiel.tech/flfeders/FEDEO/raw/branch/dev/.env.example -o /opt/fedeo/.env.example
+curl -fsSL https://git.federspiel.tech/flfeders/FEDEO/raw/branch/dev/scripts/selfhost-setup.sh -o /opt/fedeo/scripts/selfhost-setup.sh
+chmod +x /opt/fedeo/scripts/selfhost-setup.sh
+```
+
+Die Verzeichnisstruktur sollte dann mindestens so aussehen:
+
+```text
+/opt/fedeo/
+  docker-compose.yml
+  .env
+  scripts/
+  traefik/
+    letsencrypt/
+    logs/
+  postgres/
+  minio/
+```
+
+Danach:
+
+```bash
+mkdir -p /opt/fedeo/traefik/letsencrypt
+mkdir -p /opt/fedeo/traefik/logs
+mkdir -p /opt/fedeo/postgres
+mkdir -p /opt/fedeo/minio
+touch /opt/fedeo/traefik/letsencrypt/acme.json
+chmod 600 /opt/fedeo/traefik/letsencrypt/acme.json
+```
+
+Als Startpunkt kannst du die Beispielumgebung kopieren:
+
+```bash
+cp .env.example .env
+```
+
+Ersetze anschließend alle Platzhalter und passe mindestens `DOMAIN`, `CONTACT_EMAIL`, Datenbank-, Secret-, SMTP- und S3-Werte an. Seafile ist kein Teil des Standard-Stacks; wenn FEDEO später Seafile als File-Backend nutzen soll, zeigst du die Seafile-Variablen auf einen externen Seafile-Dienst.
+
+Alternativ kannst du die Konfiguration geführt erzeugen lassen:
+
+```bash
+bash scripts/selfhost-setup.sh
+```
+
+Auf einem frischen Server kannst du die Betriebsdateien und die Konfiguration direkt per One-Liner vorbereiten:
+
+```bash
+curl -fsSL https://git.federspiel.tech/flfeders/FEDEO/raw/branch/dev/scripts/selfhost-install.sh | bash
+```
+
+Der One-Liner von der Webseite nutzt den schnellen Standardpfad und startet den Stack direkt:
+
+```bash
+curl -fsSL https://git.federspiel.tech/flfeders/FEDEO/raw/branch/dev/scripts/selfhost-install.sh | bash -s -- --simple --start
+```
+
+Der Installer prüft Basispakete, installiert Docker auf Wunsch über das offizielle Docker-Installationsscript, lädt nur die Selfhost-Dateien nach `/opt/fedeo` und startet anschließend den geführten Setup-Assistenten.
+
+Für den schnellen Standardpfad:
+
+```bash
+bash scripts/selfhost-setup.sh --simple
+```
+
+Für mehr Rückfragen zu SMTP, API-Schlüsseln und optionalen Diensten:
+
+```bash
+bash scripts/selfhost-setup.sh --advanced
+```
+
+Der Assistent erklärt zuerst die Selfhost-Verzeichnisstruktur, schreibt anschließend `.env`, legt persistente Verzeichnisse inklusive `traefik/letsencrypt/acme.json` an und kann den Stack optional direkt starten.
+
+## Beispiel `.env`
+
+Diese Datei liegt neben der `docker-compose.yml`:
+
+```env

+FEDEO_BOOTSTRAP_TENANT_NAME=Mein Unternehmen
+FEDEO_BOOTSTRAP_TENANT_SHORT=MEIN
+```
+
+Die `FEDEO_BOOTSTRAP_*`-Werte sind für den ersten Start gedacht. Wenn `FEDEO_BOOTSTRAP_ADMIN_EMAIL` und `FEDEO_BOOTSTRAP_ADMIN_PASSWORD` gesetzt sind, legt das Backend idempotent einen Admin-Benutzer, einen ersten Mandanten, eine Administrator-Rolle und grundlegende Stammdaten an. Nach erfolgreichem Erstzugriff solltest du das Bootstrap-Passwort aus der `.env` entfernen oder ändern.

+Die Selfhost-Konfiguration wird im Betriebsverzeichnis als `docker-compose.yml` abgelegt. Sie startet MinIO standardmäßig mit. Wenn du stattdessen AWS S3, Hetzner Object Storage, Backblaze B2 S3 oder einen anderen externen S3-Dienst nutzen willst, kannst du die Services `minio` und `createbuckets` entfernen und nur die entsprechenden S3-Umgebungsvariablen auf den externen Anbieter zeigen lassen.
+
+Seafile wird bewusst nicht im Standard-Compose-Stack gestartet. FEDEO kann später gegen einen extern betriebenen Seafile-Dienst sprechen; dafür bleiben `SEAFILE_BASE_URL`, `SEAFILE_INTERNAL_URL`, `SEAFILE_ADMIN_EMAIL` und `SEAFILE_ADMIN_PASSWORD` als generische Anbindungswerte vorgesehen. `FEDEO_FILE_BACKEND=s3` bleibt der Standard, bis die Backend-Integration für Seafile vollständig umgesetzt ist.
+
+Das Backend führt beim Containerstart standardmäßig `npm run migrate` aus. Setze `FEDEO_RUN_MIGRATIONS=false`, wenn du Migrationen bewusst manuell ausführen möchtest.

+
+## Externe S3-Provider statt MinIO
+
+Wenn du keinen lokalen MinIO-Container betreiben willst:
+
+1. Entferne die Services `minio` und `createbuckets` aus der Compose-Datei.
+2. Entferne im Backend `depends_on` fur `minio` und `createbuckets`.
+3. Trage in `.env` die Zugangsdaten des externen S3-Dienstes ein.
+
+Beispiel fur die relevanten Werte:
+
+```env
+S3_ENDPOINT=https://s3.eu-central-1.amazonaws.com
+S3_REGION=eu-central-1
+S3_ACCESS_KEY=...
+S3_SECRET_KEY=...
+S3_BUCKET=fedeo
+```
+
+Hinweis: Das Backend nutzt `forcePathStyle: true`. Das funktioniert sauber mit MinIO und vielen S3-kompatiblen Providern. Bei reinem AWS S3 kann je nach Endpoint-Setup ein abweichendes Verhalten sinnvoll sein. Falls du AWS S3 einsetzen willst, sollte die S3-Initialisierung im Backend gegen den konkreten Zielprovider getestet werden.
+
+## Start des Stacks
+
+Im Deploy-Verzeichnis:
+
+```bash
+docker compose --env-file /opt/fedeo/.env -f /opt/fedeo/docker-compose.yml up -d
+```
+
+
+Danach Status prufen:
+
+```bash
+docker compose --env-file /opt/fedeo/.env -f /opt/fedeo/docker-compose.yml ps
+docker compose --env-file /opt/fedeo/.env -f /opt/fedeo/docker-compose.yml logs -f traefik
+docker compose --env-file /opt/fedeo/.env -f /opt/fedeo/docker-compose.yml logs -f backend
+```
+
+Wenn du Migrationen manuell ausführen möchtest:
+
+```bash
+docker compose --env-file /opt/fedeo/.env -f /opt/fedeo/docker-compose.yml run --rm backend npm run migrate
+```
+
+## Funktionsprufung
+
+Nach dem ersten Start sollten mindestens diese Checks erfolgreich sein:
+
+```bash
+curl -I https://app.example.com
+curl https://app.example.com/backend/health
+```
+
+Erwartung:
+
+- Frontend liefert `200` oder `302`
+- Backend liefert JSON wie `{"status":"ok"}`
+
+Wenn der Bootstrap aktiviert ist, kannst du dich danach mit `FEDEO_BOOTSTRAP_ADMIN_EMAIL` und `FEDEO_BOOTSTRAP_ADMIN_PASSWORD` anmelden. Die Mandantensperre wird über `locked` gesteuert; `hasActiveLicense` wird nicht mehr für den Selfhost-Zugriff ausgewertet.
+
+## Updates
+
+Vollständige Release-Updates einschließlich Compose-Datei werden mit dem Host-Skript vorbereitet und ausgeführt:
+
+```bash
+sudo python3 /opt/fedeo/scripts/selfhost-update.py check
+sudo python3 /opt/fedeo/scripts/selfhost-update.py apply --version 3.1.0
+sudo python3 /opt/fedeo/scripts/selfhost-update.py status
+```
+
+`3.1.0` durch den gewünschten veröffentlichten Release ersetzen. Das Skript benötigt Python ab 3.10 und Docker Compose ab 2.24. Es sichert die lokale Datenbank, MinIO, Konfiguration und Zertifikate vor dem Austausch, erhält `.env` und prüft die gestarteten Versionen. Während Backup und Aktualisierung gibt es eine Wartungsunterbrechung.
+
+Beim ersten Update die erzeugte Compose-Differenz prüfen, eigene Anpassungen in eine Override-Datei übertragen und den Austausch mit `--accept-compose-replacement` bestätigen. Bestehende Installationen müssen das Update-Skript zunächst aus einem passenden Release übernehmen.
+
+Unter **Administration → Systemstatus → FEDEO-Updates** können Systemadministratoren neue Releases prüfen und nach Bestätigung installieren. Dazu führt `fedeo-updater.service` die Aufträge unabhängig von Browser und Backend-Neustarts aus. Nach Bereitstellung der zugehörigen Dienstdateien installiert `sudo bash /opt/fedeo/scripts/selfhost-update-service-install.sh` den systemd-Dienst. Die aktuelle Selfhost-Compose-Datei bindet dessen lokales Socket-Verzeichnis im Backend ein. Bestehende Installationen benötigen einmalig die aktuellen Hostskripte und ein CLI-Update auf einen Release mit der Oberfläche. Einrichtung und Schritte stehen in der folgenden Anleitung.
+
+Voraussetzungen, unterstützte Konfigurationen und Wiederherstellung stehen in [Vollständige Selfhost-Updates](docs/selfhost-updates.md). Für ältere Releases steht der manuelle Ablauf in [Versionierung und Releases](docs/releases.md).
+
+## Backup-Empfehlung
+
+Regelmassig sichern:
+
+- PostgreSQL mit einem konsistenten Datenbankbackup, beispielsweise `pg_dump`
+- `./minio` falls MinIO lokal genutzt wird
+- `./traefik/letsencrypt/acme.json`
+- deine `.env`
+- deine dokumentierten Secret-Werte aus der `.env` oder deinem Secret-Management
+
+## Bekannte Betriebsbesonderheiten
+
+- Das Backend startet nur sauber, wenn alle Pflichtvariablen gesetzt sind.
+- Ohne korrekt gesetzte S3-Secrets funktionieren Dateiuploads und dateibasierte Funktionen nicht.
+- Fur die Frontend-PDF-Funktion wird eine gueltige `NUXT_PUBLIC_PDF_LICENSE` benotigt.
+- PostgreSQL ist im Projekt vorgesehen; andere SQL-Datenbanken sind in dieser Compose-Datei nicht berucksichtigt.
+
+## Optional: Nur mit bestehender externer Infrastruktur
+
+Wenn bereits vorhanden:
+
+- externer Reverse Proxy
+- externer PostgreSQL-Server
+- externer S3-Speicher
+- externe Zertifikatsverwaltung
+
+dann konnen `traefik`, `db` und `minio` aus dem Stack entfernt werden. In diesem Fall mussen die zugehorigen Hostnamen und Zugangsdaten in der `.env` beziehungsweise im Frontend-Environment auf die externe Infrastruktur zeigen.

+# 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.
+
+## Geführte Linux-Installation in FEDEO
+
+Unter **Administration → Scanner → Agent einrichten** führt ein Assistent durch die Einrichtung:
+
+1. Rechner benennen und den Agenten anlegen.
+2. Die vom Scanner-Rechner erreichbare FEDEO-Serveradresse prüfen. Ein Backend-Pfad wie `/backend` muss erhalten bleiben. Optional den Autostart bei der Linux-Anmeldung aktivieren.
+3. **Linux-Installation herunterladen**. Die Datei enthält die Software und die persönliche Konfiguration; ein Projekt-Checkout oder `npm install` ist nicht nötig.
+4. Auf dem Scanner-Rechner im Download-Ordner den angezeigten Befehl `bash fedeo-agent-<ID>.sh` ausführen, ohne vorangestelltes `sudo`. Fehlende Pakete werden auf Mint/Ubuntu/Debian über `sudo apt-get` installiert. Node.js muss mindestens Version 20 haben; bei einer älteren Distribution gegebenenfalls zuerst Node.js aktualisieren.
+5. Der Assistent wartet auf eine aktuelle Meldung des Agenten. Danach den erkannten Scanner und beispielsweise das Profil **ScanSnap iX1600: A4, Duplex, PDF, 300 dpi** wählen und abschließen.
+6. Optional **Testscan öffnen**. Der eingerichtete Agent ist vorausgewählt. Erst ein Klick auf **Scannen** startet den Einzug; das Ergebnis landet im Hauptordner des aktuellen Mandanten.
+
+Die Installationsdatei enthält einen Zugangstoken. Nach erfolgreicher Einrichtung löschen oder geschützt aufbewahren. Unter **Einrichtung öffnen** lässt sich ein bestehender Agent erneut installieren. Dafür den gespeicherten Token einfügen oder ausdrücklich einen neuen erzeugen; der bisherige Zugang wird dabei sofort ungültig.
+
+Die Installation ist je Agent getrennt:
+
+- Software: `~/.local/share/fedeo-device-agent/<ID>/`
+- Konfiguration mit Dateirechten `0600`: `~/.config/fedeo-device-agent/<ID>.env`
+- Arbeitsdateien: `~/.local/state/fedeo-device-agent/<ID>/`
+- Benutzerdienst: `fedeo-device-agent-<ID>.service`
+
+Die entsprechenden XDG-Verzeichnisse werden berücksichtigt. Der Autostart beginnt bei der Benutzeranmeldung. Ohne Autostart muss das gestartete Terminal geöffnet bleiben. Protokolle: `journalctl --user -u fedeo-device-agent-<ID>.service -f`. Eine erneute Installation ersetzt nur die Dateien dieses Agenten.
+
+### Scannerverwaltung meldet HTTP 500 nach einem Serverupdate
+
+Die älteren Scanner-SQL-Dateien `0051` bis `0053` waren nicht im Drizzle-Migrationsjournal eingetragen und wurden dadurch bei regulären Updates übersprungen. Die Vorwärtsmigration `0072_restore_instance_scan_agents` legt fehlende Tabellen und Spalten nachträglich an. Vorhandene Agenten, Tokens, Einstellungen und Scanaufträge bleiben erhalten.
+
+Zuerst einen Backend-Stand mit dieser Migration ausrollen. Bei aktiviertem `FEDEO_RUN_MIGRATIONS` wird sie beim Start automatisch ausgeführt. Bei bewusst deaktivierten Startmigrationen muss anschließend im aktualisierten Backend `npm run migrate` ausgeführt werden. Die alten Journal-Zeitstempel nachträglich einzufügen genügt bei bereits aktualisierten Datenbanken nicht.
+
+Der Datenbanktest läuft isoliert gegen ein temporäres PostgreSQL-Image und verwendet keine Anwendungskonfiguration:
+
+```bash
+cd backend
+FEDEO_TEST_POSTGRES_IMAGE=postgres:16-alpine node --import tsx tests/instanceAgentMigration.test.ts
+```
+
+## Voraussetzungen
+
+### macOS
+
+```bash
+brew install node sane-backends tesseract tesseract-lang
+scanimage -L
+```
+
+Für die Dateierstellung und Hintergrundbereinigung wird Python mit Pillow und OpenCV benötigt, beispielsweise über `npm run setup:opencv` (siehe unten). `tesseract --list-langs` muss für die Standardkonfiguration `deu` und `eng` enthalten.
+
+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 python3-pil python3-opencv tesseract-ocr tesseract-ocr-deu tesseract-ocr-eng
+scanimage -L
+```
+
+Node.js muss mindestens Version 20 haben (`node --version`). CUPS ist nur für die optionale Druckererkennung erforderlich.
+
+## ScanSnap iX1600 unter Linux per USB
+
+Der iX1600 wird vom SANE-Backend `fujitsu` per USB unterstützt. Die USB-ID ist `04c5:1632`; die WLAN-Schnittstelle wird von diesem Backend nicht unterstützt. Quellen: [SANE-Geräteliste](https://sane-project.gitlab.io/website/sane-mfgs.html), [Fujitsu-Backend](https://sane-project.gitlab.io/website/man/sane-fujitsu.5.html).
+
+1. Scanner einschalten und per USB anschließen. `lsusb -d 04c5:1632` und `scanimage -L` müssen ihn anzeigen. Den vollständigen Gerätenamen übernehmen, beispielsweise `fujitsu:ScanSnap iX1600:123456`.
+2. Den oben beschriebenen Einrichtungsassistenten verwenden. Für eine manuelle Installation kann alternativ die API `POST /api/instance-agents` als Administrator einen Agenten und dessen einmalig ausgegebenen Token erstellen.
+3. Im Verzeichnis `agents/fedeo-device-agent` die Abhängigkeiten installieren und konfigurieren:
+
+   ```bash
+   npm ci
+   cp .env.example .env
+   chmod 600 .env
+   nano .env
+   ```
+
+   ```env
+   FEDEO_URL=https://deine-fedeo-instanz
+   FEDEO_AGENT_TOKEN=fedeo_agent_DEIN_TOKEN
+   FEDEO_SCANNER_NAME="fujitsu:ScanSnap iX1600:DEINE_SERIENNUMMER"
+   FEDEO_SCAN_SOURCE="ADF Duplex"
+   FEDEO_SCAN_FORMAT=pdf
+   FEDEO_SCAN_RESOLUTION=300
+   FEDEO_SCAN_MODE=Color
+   FEDEO_SCAN_POSTPROCESS=false
+   FEDEO_SCAN_BACKGROUND_CLEANUP=true
+   FEDEO_SCAN_OCR=true
+   FEDEO_SCAN_OCR_LANGUAGE=deu+eng
+   FEDEO_SCAN_TIMEOUT_SECONDS=900
+   ```
+
+   `FEDEO_URL` ist die Basis-URL, unter der `/instance-agent/heartbeat` erreichbar ist, ohne zusätzliches `/api`.
+4. `npm run build` und `npm start` ausführen. In FEDEO muss der Agent als online erscheinen.
+5. In der Scannerverwaltung das erkannte Gerät wählen, **ScanSnap iX1600: A4, Duplex, PDF** anklicken und speichern.
+6. Papier einlegen. Unter **Dateien → Scan** den Agenten wählen und **Scannen** anklicken. Der gesamte Stapel landet als ein PDF im aktuellen Ordner. Für den ersten Test zwei Blätter mit markierten Vorder- und Rückseiten verwenden: Das PDF muss vier Seiten in dieser Reihenfolge enthalten.
+
+Der Agent liest im SANE-Batch-Modus bis zum leeren Einzug. Vorder- und Rückseiten werden in der vom Scanner gelieferten Reihenfolge gespeichert, einschließlich leerer Rückseiten. Es gibt keine automatische Leerseitenentfernung. „ADF Front“ scannt einen Stapel einseitig, „Flatbed“ eine einzelne Seite. Einzug-Scans benötigen PDF; PNG und TIFF sind für Einzelseiten verfügbar. Die Optionen entsprechen dem [scanimage-Handbuch](https://sane-project.gitlab.io/website/man/scanimage.1.html).
+
+**Papierformat:** Das iX1600-Profil verwendet A4 mit 210 × 297 mm, einschließlich der Fujitsu-Einstellungen für die Papiergröße. Für andere Größen die Einstellung anpassen; „Scanner-Vorgabe“ übernimmt den am Treiber eingestellten Scanbereich. Die SANE-Quellen und Optionen lassen sich ohne Scan mit `scanimage -d 'DEIN_GERAETENAME' --source 'ADF Duplex' --help` prüfen.
+
+**USB-Zugriff:** Wenn `lsusb` das Gerät sieht, `scanimage -L` jedoch nicht, zuerst Kabel, Stromversorgung, SANE-Version und Zugriffsrechte prüfen. Debian/Ubuntu/Mint liefern normalerweise passende udev-Regeln mit `libsane-common`. Andere Scanprogramme schließen. Einen dauerhaft laufenden Agenten unter einem Benutzer betreiben, der ebenfalls mit `scanimage -L` auf das Gerät zugreifen kann.
+
+**Lange Stapel und Fehler:** Das Scan-Zeitlimit beträgt standardmäßig 15 Minuten; die Dateierstellung hat ein eigenes gleich langes Limit. Der Agent hält seinen Online-Status währenddessen aktuell. Der Dialog kann im Hintergrund weiterlaufen; Schließen stoppt den Scan nicht. Verbindungsfehler beim Abfragen des Status lösen keinen neuen Scan aus. Bei Papierstau, unvollständigem Duplex-Scan oder Uploadfehler wird kein automatischer erneuter Papiereinzug gestartet. Die Rohseiten bzw. die fertige Datei bleiben im gemeldeten Arbeitsverzeichnis zur Wiederherstellung erhalten. Nach erfolgreichem Upload werden sie gelöscht. Das Upload-Limit beträgt 100 MiB pro PDF; gegebenenfalls den Stapel teilen oder die Auflösung reduzieren.
+
+## Konfiguration

+Nach Änderungen am Agenten oder am Linux-Installationsskript das im Frontend ausgelieferte Paket neu erstellen und mitcommitten:
+
+```bash
+npm run build:installer
+```
+
+`npm test` prüft mit `check:installer`, dass das Paket dem aktuellen Quellcode entspricht. Das Paket enthält keine Zugangsdaten; diese ergänzt erst der Browser beim Download. Die Installer-Tests verwenden temporäre Verzeichnisse und simulierte Systembefehle.
+
+## Scannerhintergrund und OCR
+
+Hintergrundbereinigung und OCR sind standardmäßig aktiv und lassen sich in **Administration → Scanner** als Vorgabe oder im einzelnen Scan-Dialog einstellen:
+
+- **Scannerhintergrund weiß machen:** Bei einem kleinen Bon oder Dokument werden sicher erkannte Flächen außerhalb des Papiers weiß. Seitengröße, Position und Inhalt des Papiers bleiben erhalten. Unsichere Papiergrenzen werden nicht verändert. Diese Verarbeitung ist unabhängig vom zusätzlichen Zuschnitt.
+- **Durchsuchbares PDF (OCR):** Der Agent erkennt nach der Bildverarbeitung Text mit Tesseract und bettet ihn direkt in das PDF ein, bevor er es hochlädt. Das gilt auch für normale Dateien ohne Eingangsbeleg. Deutsch und Englisch sind vorausgewählt; PNG und TIFF erhalten keine OCR-Textschicht. Die Darstellung bleibt das gescannte Bild, ergänzt um auswählbaren und durchsuchbaren Text ([Tesseract-Dokumentation](https://tesseract-ocr.github.io/tessdoc/Command-Line-Usage.html)).
+
+```env
+FEDEO_SCAN_BACKGROUND_CLEANUP=true
+FEDEO_SCAN_OCR=true
+FEDEO_SCAN_OCR_LANGUAGE=deu+eng
+```
+
+Nach einem Update von FEDEO bestehende Agenten über **Einrichtung öffnen** mit dem neuen Linux-Installer aktualisieren. Dieser installiert auch OpenCV, Tesseract und die Sprachpakete. Bei manueller Installation die oben genannten Pakete und die aktuelle Agent-Software installieren und den Dienst neu starten. Der Agent meldet die verfügbare Verarbeitung beim Start an FEDEO; fehlende Fähigkeiten werden vor dem Auftrag gemeldet. Zusätzlich prüft er die benötigten Pakete und die gewählte OCR-Sprache vor jedem Papiereinzug. Ein OCR-Fehler erzeugt keinen erfolgreichen Scan ohne Textschicht; die Rohseiten bleiben zur Wiederherstellung erhalten.
+
+Die OCR läuft innerhalb des Scan-Auftrags nach dem Einzug. Bei langen Stapeln kann dieser Schritt länger dauern; das Zeitlimit für die Dateierstellung wird ebenfalls über `FEDEO_SCAN_TIMEOUT_SECONDS` gesetzt. Leere Rückseiten und Seitenreihenfolge bleiben erhalten.
+
+## Zusätzliche 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, sonst `python3`. Pillow ist auch ohne Bildkorrektur für die Dateierstellung erforderlich. Falls die zusätzliche Korrektur fehlschlägt und `FEDEO_SCAN_POSTPROCESS_STRICT=false` gesetzt ist, werden die betroffenen Rohseiten weiterverarbeitet; die Warnung erscheint im Scan-Ergebnis. Fehlendes OpenCV kann nur bei ausgeschalteter Hintergrundbereinigung toleriert werden. Beim iX1600-Profil ist der zusätzliche Zuschnitt ausgeschaltet, damit der vollständige A4-Scan erhalten bleibt; Hintergrundbereinigung und OCR sind eingeschaltet.
+
+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, Tesseract einschließlich Deutsch/Englisch 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
+```
+
+## Tests
+
+```bash
+npm test
+npm run test:python
+```
+
+Die Tests benötigen Python 3 mit Pillow, NumPy und OpenCV. Für den OCR-Integrationstest sind Tesseract mit `deu`/`eng` und `pdftotext` aus Poppler erforderlich; ohne diese Programme wird er übersprungen. Bei Verwendung der virtuellen Umgebung zuerst `. .venv-opencv/bin/activate` ausführen. Die Tests simulieren `scanimage`, erstellen echte PDFs und prüfen Duplex-/Simplex-Stapel, Seitenreihenfolge, Auflösung, leeren Einzug, Papierstau, beschädigte Seiten, Dateinamen und OpenCV-Ausfälle. Bildtests prüfen die Hintergrundbereinigung bei geraden und schrägen Bons sowie den Erhalt von Text, farbigen Logos und vollständigen Seiten. Der OCR-Test liest die tatsächliche PDF-Textschicht einschließlich leerer Rückseiten aus. Ein Test mit angeschlossenem iX1600 bleibt zusätzlich erforderlich.
+
+Hardwareprüfung am 17.09.2026: ScanSnap iX1600 per USB unter Linux Mint 22.3 mit SANE 1.2.1. Zwei A4-Blätter wurden mit 300 dpi in Farbe beidseitig gescannt; das erzeugte PDF enthält vier A4-Seiten in der Reihenfolge Vorderseite/Rückseite. Alle vier Seiten wurden visuell geprüft. Der Test umfasste den lokalen Agenten bis zur PDF-Erstellung; der FEDEO-Upload wird separat mit einem simulierten Dateispeicher getestet.
+
+## 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`.

+# Projekt To-Do Liste
+
+## ✅ Erledigt
+- JWT-basierte Authentifizierung mit Cookie
+- Prefix für Auth-Tabellen (`auth_users`, `auth_roles`, …)
+- `/me` liefert User + Rechte (via `auth_get_user_permissions`)
+- Basis-Seed für Standardrollen + Rechte eingespielt
+- Auth Middleware im Frontend korrigiert (Login-Redirects)
+- Nuxt API Plugin unterstützt JWT im Header
+- Login-Seite an Nuxt UI Pro (v2) anpassen
+- `usePermission()` Composable im Frontend vorbereitet
+
+---
+
+## 🔄 Offene Punkte
+
+### Backend
+- [ ] `/me` erweitern: Rollen + deren Rechte strukturiert zurückgeben (`{ role: "manager", permissions: [...] }`)
+- [ ] Loading Flag im Auth-Flow berücksichtigen (damit `me` nicht doppelt feuert)
+- [ ] Gemeinsames Schema für Entities (Backend stellt per Endpoint bereit)
+- [ ] Soft Delete vereinheitlichen (`archived = true` statt DELETE)
+- [ ] Swagger-Doku verbessern (Schemas, Beispiele)
+
+### Frontend
+- [ ] Loading Flag in Middleware/Store einbauen
+- [ ] Einheitliches Laden des Schemas beim Start
+- [ ] Pinia-Store für Auth/User/Tenant konsolidieren
+- [ ] Composable `usePermission(key)` implementieren, um Rechte einfach im Template zu prüfen
+- [ ] Entity-Seiten schrittweise auf API-Routen umstellen
+- [ ] Page Guards für Routen einbauen (z. B. `/projects/create` nur bei `projects-create`)
