+| `xmpp.srv_s2s`             | Verifies that server-to-server SRV records (_xmpp-server / _xmpps-server) are published and resolvable.           | CRITICAL            |

+| `xmpp.sasl_mechanisms`     | Reviews the c2s SASL mechanisms offer (presence of SCRAM, absence of password-equivalent PLAIN-only).             | CRITICAL            |
+| `xmpp.s2s_dialback`        | Verifies that s2s endpoints advertise dialback or SASL EXTERNAL after TLS (federation auth).                      | CRITICAL            |
+| `xmpp.ipv6_reachable`      | Flags deployments that are only reachable over IPv4.                                                              | INFO                |
