        #     dev/release/beta; CI runs on dev by definition, and

        #     noise here because this workflow installs only a subset of
        #     the runtime deps (HA + requirements*.txt); main CI already
        #     gates pylint on real PRs.

        # from a check-only hook (flake8 / yamllint / ci-custom) is a
        # real issue and fails the workflow loudly. Same SKIP list as
