The pass that answers *what does this node offer* takes a failed resolution to
mean it learned nothing about that node. So refusing an unanswerable
requirement there made the machine disappear — and every other machine was then
told, wrongly, that the two of them shared no private network.
A wrong answer about a machine nobody asked about, caused by a fault on a
third. The lab found it: one module needing a licence that had not been added
yet made two unrelated machines look disconnected.
The second pass still refuses it, where the question is actually being asked.
