Turn the physical-host sketch into an operator runbook covering
cluster identity, interface and bearer setup, link validation,
failure/rejoin testing, diagnostic capture and cleanup.
Explain the cluster-domain-socket analogy and identify a future
`pyroute2` TIPC codec as the path from manual `tipc(8)` commands to
the same netlink management stack planned for WireGuard.
Authorize `host_a_srv` by its stable import name so direct script
execution does not expose only `__main__` while host B requests the
callable's actual `NamespacePath`.

`gpt-5.6-sol` (`openai`))
