"""
The two answers a person now gives, in the real application, in both engines.

An invitee answers an invitation on the home page (harness/invitation_probe.py);
a group owner answers a node that asked to host the group, and sees who was
invited and has not answered (harness/group_hosts_probe.py). The hub side is
`test_invitations_and_hosts.py`; this is where it meets the interface.
