What issue are you seeing?

While working on a project, I found that I had added .codex/config.toml (alongside rules and other items), and it confusingly wasn't working. It took a few reads of the config documentation to realize this was because the project wasn't a trusted project. (As an aside: I believe I observed .codex/rules were being used still, which I'm not sure is inconsistent with the project trust)

While I may have been prompted for it initially on the project, there was no entry in my ~/.codex/config.toml for the directory.

This would have been far less confusing if there was a warning on start when there was no trust setting (untrusted or trusted) for the directory when there was a configuration there that would otherwise not be respected.

What steps can reproduce the bug?

• Add .codex/config.toml to project directory
• Start project w/o trust setting

I wasn't sure why I was not getting a prompt re: trust.

What is the expected behavior?
