  # The rerun extra supports more than one rerun minor; the default environment
  # resolves the newest of them. This job runs the rerun tests against the floor
  # of that window, so the older minor is supported in fact and not just on paper
  # (bencher calls rerun.experimental, which is where an alpha API moves).

  # build goes through save_result -> load_result -> render. Catches any divergence
  # between in-process and split rendering (unpicklable result types, render paths
  # that relied on live state). See bencher/render.py and test/test_render.py.
