Research direction
Start with the pyclbr.readmodule_ex entry point and reproduce traversal of an import of main, observing the ValueError involving main.spec. Review the linked python/cpython#24623 pull request for the proposed resolution and verify that the issue no longer occurs without changing unrelated module-traversal behavior.
