Research direction

Start with the assertion at src/unix/core.c:303 and try to reproduce the crash on Debian 12 with uvloop 0.24 and Python 3.13.0. The report does not provide a reproducer, debug-mode result, or comparison with vanilla asyncio, so the failure conditions and a verifiable fix remain to be established.

Written by the indexing model from the issue text.
