+# Same shape in every commit-check repository: monthly, one grouped pull
+# request per ecosystem, `chore(deps)` commit subjects. The one exception is
+# pip here, which stays daily with no cooldown: requirements.txt pins the
+# commit-check release this action ships, and a new release should reach the
