Research direction
Start by reproducing the two edits shown in test.py with dmypy run test.py, comparing the initial and post-change diagnostics. Trace dmypy’s incremental handling of ignore-without-code and unused-ignore errors; done means the changed file reports the expected error instead of incorrectly returning success.
