+## 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.

 ## 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.
-
-Vor kritischen Updates sollte ein Backup der persistenten Daten erstellt werden:
+Vollständige Release-Updates einschließlich Compose-Datei werden mit dem Host-Skript vorbereitet und ausgeführt:
 
 ```bash
-cd /opt/fedeo
-tar -czf "backup-$(date +%Y%m%d-%H%M%S).tar.gz" .env postgres minio
+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
 ```
 
-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
-cd /opt/fedeo
-curl -fsSL https://git.federspiel.tech/flfeders/FEDEO/raw/branch/dev/docker-compose.selfhost.yml -o /opt/fedeo/docker-compose.yml

-docker compose --env-file /opt/fedeo/.env -f /opt/fedeo/docker-compose.yml up -d
-```
+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
-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.
+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:
 
-- `./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_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.

+## Scannerhintergrund und OCR
+
+Hintergrundbereinigung und OCR sind standardmäßig aktiv und lassen sich in **Administration → Scanner** als Vorgabe oder im einzelnen Scan-Dialog einstellen:

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)).

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.
