Hi @hn-yu, thanks for filling this bug. I just tried your prompt on my sandbox git project that I use to test codex and did not encounter any issues with
gpt-5.1-codex-max:<img width="1258" height="1010" alt="Image" src="https://github.com/user-attachments/assets/86528685-090b-43b6-befc-28f17fb9f4be" />
