docker-compose.smoke.yml

# CI overlay for the compose smoke: the same stack, with a stand-in for the
# Modal data plane in place of the real one.
#
#   scripts/compose-smoke.sh
#
# The stand-in answers the control plane's sandbox endpoints and then plays the
# sandbox, dialing back over the compose network. Nothing here reaches a cloud,
# so the smoke runs on a fork's pull request with no secrets.
