      # build setting pick one at build time, so it validates the debug/ and
      # release/ artifact slots together (and `--download skip` refuses an
      # incomplete slot). Please don't "optimise" this down to one flavor.

      # from the Release tarballs, then debug/ is dropped and refilled from the
      # Debug tarballs while release/ is left alone. hermes-engine is fetched
      # from Maven by the command itself.
