  # This job exists for our branch protection rule.
  # We want to require status checks to pass before merging, but the set of
  # checks that run for any given PR is dynamic based on the files changed.
  # When creating a branch protection rule, you have to specify a static list
  # of checks.
  # So since this job always runs, we can specify it in the branch protection rule.
