  Manage subnet membership — create a subnet, show a pairing code to invite a machine, or join
  an existing one. Use when the user wants to pair machines, set up a subnet, or reach agents
  across machines. Cross-machine /sptc:send and live agents depend on it.

Pairs machines into a private network so agents reach each other across nodes.
