	# The success job is here to consolidate the total success/failure state of
	# all other jobs. This job is then included in the GitHub branch protection
	# rule which prevents merges unless all other jobs are passing. This makes
	# it easier to manage the list of jobs via this yml file and to prevent
	# accidentally adding new jobs without also updating the branch protections.
