+# This workflow is intended to follow testing as performed manually
+# by an actual developer. This includes using make and relying on docker
+# or podman CLI to build images.
+# The intent is to verify that developers can run these tests locally,
+# with no, or at worst minimal, modifications.
+# As such, all changes, that would lead to divergence with recommended
+# developer practice, must be justified in comments.
+# Divergence:
+# SOURCE_BRANCH variable value is set for each execution of make,
+# since the actions/checkout execution switches to a single commit.
