调研方向

Start by reading BPO issue 20518 and the uploaded patch 33997, then investigate the reported multiple-inheritance behavior in CPython's extension modules. The payload does not identify a test or define the expected base value, so completion requires clarifying the intended behavior before validating a fix.
