      # Doc-sync gates (doc-sync-enforcement RFC). doc-typecheck compiles the
      # fenced ts blocks against the root project-reference graph. The cordis
      # catalog freshness check, type-equiv check, and markdown wrap/link checks
      # only read source. Same `doc-sync` script the pre-push hook runs
