+## 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.

 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.

 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.
 
-## Docker Compose mit optionalem S3 und Matrix
+## Docker Compose mit optionalem S3
 
 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.

 ## Updates
 
-Script-installierte Instanzen liegen standardmassig unter `/opt/fedeo`. Ein Update besteht daraus, die Selfhost-Dateien zu erneuern, die vorgebauten Images zu ziehen und den Compose-Stack neu zu starten.
+Vollständige Release-Updates einschließlich Compose-Datei werden mit dem Host-Skript vorbereitet und ausgeführt:
-
-Vor kritischen Updates sollte ein Backup der persistenten Daten erstellt werden:
 
 ```bash
-cd /opt/fedeo
+sudo python3 /opt/fedeo/scripts/selfhost-update.py check
-tar -czf "backup-$(date +%Y%m%d-%H%M%S).tar.gz" .env postgres minio
+sudo python3 /opt/fedeo/scripts/selfhost-update.py apply --version 3.1.0
+sudo python3 /opt/fedeo/scripts/selfhost-update.py status
 ```
 
-Danach die aktuellen Selfhost-Dateien laden und den Stack aktualisieren:
+`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.
 
-```bash
+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.

-Der Backend-Container wendet Datenbankmigrationen beim Start automatisch an, solange `FEDEO_RUN_MIGRATIONS` nicht deaktiviert wurde. Falls Migrationen manuell erzwungen werden sollen:
+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.
 
-```bash
+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).
-docker compose --env-file /opt/fedeo/.env -f /opt/fedeo/docker-compose.yml run --rm backend npm run migrate
-docker compose --env-file /opt/fedeo/.env -f /opt/fedeo/docker-compose.yml up -d
-```
-
-Anschliessend den Zustand prüfen:
-
-```bash
-docker compose --env-file /opt/fedeo/.env -f /opt/fedeo/docker-compose.yml ps
-curl -I https://app.example.com
-curl https://app.example.com/backend/health
-```
-
-Die Selfhost-Compose-Datei nutzt vorgebaute Images. Dadurch braucht der Server keinen Repository-Checkout und keine lokalen Build-Kontexte.
 
 ## Backup-Empfehlung
 
 Regelmassig sichern:
 
-- `./postgres`
+- PostgreSQL mit einem konsistenten Datenbankbackup, beispielsweise `pg_dump`
 - `./minio` falls MinIO lokal genutzt wird
-- `./matrix/postgres` falls Matrix lokal betrieben wird
-- `./matrix/synapse` falls Matrix lokal betrieben wird
 - `./traefik/letsencrypt/acme.json`
 - deine `.env`
 - deine dokumentierten Secret-Werte aus der `.env` oder deinem Secret-Management

+## 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.

+## 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_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.
