Research direction

The issue identifies Mock.call_args and Mock.call_args_list as the affected behavior, but mentions no source file, test, or entry point. Start by locating the unittest.mock Mock implementation and existing call-tracking tests, then reproduce the parent-child Mock case described by the title. Done means the propagation behavior is corrected and covered by tests.
