process_check.sh ran `systemctl is-active <entity-name>`, but a service's name is a logical label, not its unit/container name — matrix is matrix-synapse.service + element-web/mautrix-* containers, authentik is authentik-server/-worker containers. So every multi-component or docker service reported "inactive" while up (authentik, matrix, photos, house, arr-stack, …). Resolve in order: exact systemd unit, a unit with the name as prefix (matrix -> matrix-synapse.service), or a running docker container whose name contains it. checkdefaults passes a declared probe_unit/systemd_unit/container attribute when set, for precision.
