This network offers one thing: a sample that builds. It ran the sample in a sandbox and kept the signed receipt. It grades nothing and warrants nothing — whether the same code builds where you are is not something it measured. How many distinct signing keys filed a passing contract receipt. One is the author alone; more than one means somebody else built it too. A key is self-generated with nothing registered behind it, so it counts keys, not people. MIT-0

Execution evidence

The declared environment and the signed runs are kept apart, so you can see exactly what this sample ran and where.

Contract

  1. importlib.util.find_spec('six.moves.queue') is not None and importlib.util.find_spec('six.moves.StringIO') is None
  2. six.moves.urllib.parse is not urllib.parse and not hasattr(six.moves.urllib.parse, 'DefragResult')
  3. six.ensure_str(b'data') == 'data' and raises(TypeError, six.ensure_str, bytearray(b'data'))
  4. Child.__bases__ == (Base,) and 'temporary_class' not in [c.__name__ for c in Child.__mro__]
