Research direction
The report identifies ZipFile opened in append mode and labels the problem as Windows-specific, but names no source file, reproducer, or test. Start by reproducing the invalid archive, then locate the standard-library ZipFile implementation and relevant tests; done means an append-mode archive is accepted as a valid ZIP.
