+# For security, CI jobs triggered by a GitHub pull request should only run on
+# Airflow infra when they are from a user that is in this list.
+# 
+# This list consists of the airflow committers and other known, trusted
+# authors. Currently maintained by hand; and the AWS SSM parameter is still
+# the source of truth, so changes here must also be replicated there.
