Say the node's facts in its haves alone, and enrol through the seat alone

The CONTROL stream the facts, the enrolment and the overlay rekey were published into was the controller's, which ended
by its unassignment (issue 1126) and whose stream is removed after group B's delivery: a publish there would fail every
facts event before its haves are written. The facts go into the haves as they did after the report, the enrolment goes
through mesh-enrolment alone, and overlay take is refused because no seat takes a rekey now.
