create_outputs and scanning declare expected with a default of None but dereference it unconditionally (expected.get(...)), so calling either without it raises AttributeError, although the parameter is documented optional. Guard the expected-value checks with `if expected is not None:`. The self-test, which always passes expected, is unaffected.

if expected is not None:. The self-test, which always passesexpected, is unaffected; a standalone call withexpected=Nonenow returns its result instead of raising.If the harness coupling is intentional, I am happy to close this or turn it into a docs note instead.
