Pass the controller's first-node gate on one reading after the witness window

The controller runs on one machine, so three readings over two minutes guarded no
other machine and held every walk behind it. Judge each module by its own rule:
one reading for the controller and the tool runner once the node-engine's witness
window has ended, one for mesh-delivery, three for the node-engine and the
resolver with the first two minutes after the send (novox/hq ADR 0351). The
gate's verdict names the rule it applied.
