`tmp` foder in .codex

What version of Codex CLI is running?

codex-cli 0.99.0

What subscription do you have?

Plus

Which model were you using?

gpt-5.3-codex

What platform is your computer?

WSL

What terminal emulator and version are you using (if applicable)?

WSL

What issue are you seeing?

I have set these values in config.toml.

[sandbox_workspace_write]
exclude_tmpdir_env_var = false  # Allow $TMPDIR
exclude_slash_tmp = false       # Allow /tmp

But codex cli still creates tmp folder in my .codex folder. It is very problematic on Windows + WSL environment because some cloud backup tools doesn't recognize the files created by WSL.

Please don't say "Setup your backup tool". As describe above, I have set enough settings so the codex can create files in tmp folder.

Thanks

What steps can reproduce the bug?

1. Setup config.toml
2. Launch codex
3. path (may be wrong) is not created but arg0 is still created in .codex/tmp folder (files: .lock, apply_patch, applypatch, codex-linux-sandbox)

What is the expected behavior?

Use the /tmp or $TMPDIR instead.
