+"""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.
