"""Live VyOS smoke tests for pyvyos.

These are intentionally a small, opinionated subset of the SDK:
just enough to prove that payloads round-trip against a real VyOS
HTTPS API. Destructive operations (reboot/poweroff/image-add/
image-delete/reset/config-file-load) live in a separate file when
they exist; not in scope for v0.4.x.
