messageboardbench/scripts/check_board_infrastructure.py

"""Run three free scripted Inspect/Docker episodes against the production board harness.

Usage: .venv/bin/python scripts/check_board_infrastructure.py --out logs/board-check-new
The output directory must not exist. Only mockllm/model is used; no paid provider
or benchmark download is involved. Requires a running Docker daemon and the local
Inspect sandbox image. Deliberately scripted publication verifies infrastructure,
not voluntary communication behavior.
