The `clean-branches` recipe runs under `set -euo pipefail`. The default-branch detection assigned from `git symbolic-ref refs/remotes/origin/HEAD`, which fails (quietly) in the Actions checkout where origin/HEAD isn't configured. Under pipefail+errexit that failing pipeline aborted the whole recipe *before* the intended fallback (`git remote show origin` -> `main`) could run, so the scheduled job always exited non-zero. Guard the assignment with `|| true` so the fallback chain runs. Also fix the remote-branch filter `grep -E '^origin/.\+'` (matched a literal `+`, so it silently matched nothing) to `'^origin/.+'`.
