Research direction

Start by tracing the Python copy2 entry point and compare its metadata behavior on Windows and macOS. The issue names no files, tests, or expected metadata details, so first establish the affected metadata and platform-specific behavior; done means copy2 consistently preserves the intended metadata on both systems.
