	# This job tests that the patches apply cleanly, and nothing else. The goal is to test this as
	# quickly as possible. This job is a good signal for devs: GitHub Actions is quick to get an agent,
	# so when this job fails, it's easy to see, and clear to the dev that the rest of the PR's jobs
	# aren't going to succeed and can be ignored.
	#
	# Ideally, failure of this job would block the tests from running, because it would be a waste of
	# time to hit the patch failure N times. However, the actual tests run in AzDO, so we can't
	# reasonably cancel them from here (GitHub Actions).

	# The "0:" prefix makes this workflow's checks sort above the alphabetical AzDO stage names on the
	# PR checks list, so patch failures are immediately visible without scrolling.
