What subscription do you have?
Pro

Linux 6.17.0-19-generic x86_64 unknown
What terminal emulator and version are you using (if applicable)?
wezterm 20240203-110809-5046fc22
What issue are you seeing?
When I run codex in my project, it creates a .codex file marked as read-only in the root.
Codex itself then reports that the repo is dirty.
It also cannot update files in my .ai directory in the repo itself without going out of sandbox (not sure if related)
What steps can reproduce the bug?
Run codex
run ls -al .codex from another shell in the same directory
What is the expected behavior?
There is no file

Search in github is not really good, that issue did not surface when I searched for ".codex"...
