      # tests/test_reference.py pins the README's published figures as golden
      # values against the bundled sample. The point of running it here is that
      # main once carried a suite that could not even be collected -- the tests
      # imported a package that did not exist on the branch -- while the README
      # claimed the numbers those tests were supposed to guard.
