// Issue #1753 crossed three runtime boundaries: report authentication, host to
// provider-node linking, and canonical presentation. Keep those boundaries in
// one regression test so two valid agents from independent sites cannot be
// mistaken for an auth failure or collapsed merely because both PVE machines
// report the same native short hostname.
