# `wai dev` runs the room in remote desktop mode, and host.sh shares a drawn pattern into it for
# a few seconds, recording the session. The room service must hold the host's screen, and the
# repository's independent verifier must accept the recorded session.

# WAI_ROOM_BIN, WAI_WEB as `wai dev` takes them), and python3.
# No -e: each check records its own result, and the run goes on to the next.
