Timer-App unter Versionsverwaltung stellen
Stand der laufenden Anwendung von 192.168.1.5:/opt/timer-app (systemd-Dienst timer-app, Port 3003). Zeiterfassung mit Kostenberechnung: Node/Express, SQLite, Anmeldung ausschliesslich ueber Authentik (OIDC, PKCE, RP-Logout) - der frueher vorhandene Passwort-Login ist entfernt. Nicht im Repo, bewusst: - backend/.env und die .env-Sicherung: enthalten Session-Secret und die Authentik-Zugangsdaten. Vorlage ist backend/.env.example. - data/: die Datenbank mit den echten Zeiterfassungen. - node_modules/. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
