EXTENSIONS

Run one argv vector, push bytes atomically, and wait for SSH host keys on any host, under an explicit strict or trust-on-first-use host-key policy. One generic model with no host in its definition; every method takes its target as arguments and stores data keyed by host.

Reach inside a systemd-nspawn machine over SSH+nsenter: snapshot state, run an argv, read/write files atomically (with backup), and restart/inspect units — a reusable container transport.

General-purpose NATS transport for swamp — exec, upload, wait for agent connection. Pairs with swamp-nats-agent (https://github.com/retr0h/swamp-nats-agent).
