+# The golangci-lint version lives in hack/golangci-lint.version, which Dependabot
+# cannot parse. This bumps it and opens a PR.
+#
+# Events caused by GITHUB_TOKEN start no workflows. AUTOMATION_SSH_KEY is an optional
+# repository secret holding the private half of a deploy key with write access; the
+# branch is pushed over SSH with it, so pushes to an open PR run ci.yaml. Opening the PR
+# is still a GITHUB_TOKEN event, so a new PR gets its checks from a dispatched run on
+# its branch, as workflow_dispatch is the exception to that rule.
