Fast mode shows up even if admin disabled it

What version of the Codex App are you using (From “About Codex” dialog)?

Version 26.422.20832 (2025)

What subscription do you have?

Enterprise

What platform is your computer?

Darwin arm64

What issue are you seeing?

Even after setting below policy through cloud-managed requirements.toml, I am able to toggle /fast from Codex app. I don't know if codex is working in "fast" mode or "standard" mode and where the bug is.

[features]
fast_mode = false

What steps can reproduce the bug?

1. Add the above policy following https://developers.openai.com/codex/enterprise/admin-setup#step-3-configure-codex-local-requirements
2. Restart codex-cli. You won't see a way to toggle /fast anymore.
3. Restart Codex app. /fast mode can still be toggled and the session doesn't show any errors during prompts.
4. VSCode extension has a similar experience as Codex app

What is the expected behavior?

As an admin, we want to disable fast mode for our engineers and be 100% sure that it is indeed disabled. I don't know if it is a UI bug or backend bug or both.

Additional information

At the very least, please tell if there is a way to verify if the fast mode of using token is disabled and it won't work. If there is some other way to correctly disable it, let us know that too.
