Overall it looks good to me, I just left a couple of comments/questions in https://review.openstack.org/#/c/147645/17/contrib/heat_mistral/heat_mistral/tests/test_workflow.py <https://review.openstack.org/#/c/147645/17/contrib/heat_mistral/heat_mistral/tests/test_workflow.py> Could you please take a look?

Either we need to do in Heat itself to restore those references accounting for stack name etc.. Or we need to provide some facility in Mistral itself.
