      # Keep every explanation out of the run block below: it is a folded scalar, so YAML
      # joins its lines into one command and a '#' would comment out everything after it.
      # --max-public-candidates tracks the measured PublicCandidate count with no slack
      # (docs/dead-code-scanner.md). Lower it whenever triage removes a candidate, and
      # raise it only together with the reason the new candidate has to stay.
