"""`scripts/booth` — the surface every fleet session actually calls.

It had no tests at all, which the 2026-09-22 bug-hunt panel found the hard way:
its guard-strength table returned UNVERIFIED for every CLI claim because nothing
in the suite executes the script. Two of that round's findings live in here.

These run the real script under the real system `python3` with no venv, which
also makes them a live check on INV-1 (stdlib-only): a third-party import in
`marks.py` fails here the same way it fails on a fleet host.
