+# There is no concurrency group, on purpose. Dependabot labels a pull request as
+# it opens it, so one pull request starts several runs at once, and with
+# cancel-in-progress the cancelled ones kept this required check from passing and
+# held the merge. Each run reads only its own event and takes seconds, so all of
+# them finish. Nor does a job-level `if` skip label events other than
+# `changelog`: a skipped run passes a required check, so any label added to a
+# pull request that edits the file would clear its failure.
