-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).
