If ssh-keyscan returns no host key, the setup status was still written with an empty transport_ssh_server_fingerprint. Superhubs then rendered an empty known_hosts entry for the host and the rsync pull later failed with "Host key verification failed". Gate the status update on a non-empty fingerprint and retry on subsequent runs.
