-| `srv_records_present`         | At least one SRV record is published for this service.                                            | CRITICAL            |
-| `srv_null_target`             | Detects SRV records with target `.`, signaling the service is intentionally not available.        | WARNING             |
-| `srv_target_not_cname`        | RFC 2782: SRV targets must resolve directly to A/AAAA, not through a CNAME.                       | WARNING             |
-| `srv_targets_resolve`         | Every SRV target resolves to at least one A/AAAA address.                                         | CRITICAL            |
-| `srv_port_valid`              | SRV records advertise a non-zero port that clients can actually connect to.                       | CRITICAL            |
-| `srv_priority_weight_sanity`  | Priority/weight values follow RFC 2782 conventions (failover present, weights meaningful).        | WARNING             |
-| `srv_tcp_reachable`           | Every TCP SRV `target:port` accepts a TCP connection.                                             | CRITICAL            |
-| `srv_udp_reachable`           | UDP SRV targets do not return ICMP port-unreachable.                                              | WARNING             |
-| `srv_redundancy`              | At least two distinct SRV targets exist (avoids single point of failure).                         | INFO                |
