[Bug] Codex Mac Desktop app does not load user level config.toml

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

Version 26.527.30818 (3370)

What subscription do you have?

Business

What platform is your computer?

Darwin 25.4.0 arm64 arm

What issue are you seeing?

Codex desktop app is not loading ~/.codex/config.toml. I have developer instructions in there which are not being followed. Note that this works in CLI.

What steps can reproduce the bug?

1. Install codex version as stated
2. Go to Settings > Profile > Configuration > "Global Config / User Config" > Open config.toml
3. Edit the file to add some developer instructions. For example, I added

developer_instructions = """
Follow the developer instructions here absolutely. If you want to deviate from it, tell the user that you found this instruction and ask for permission to go outside of the instructions below.

1. When setting environment variables for a single command, use the explicit `env VAR=value command ...` form instead of leading assignment syntax like `VAR=value command ...`. This keeps Codex exec policy prefix rules matchable.
2. When creating git commits use the 50/72 rule. 50 lines for the title and 72 lines for the description. Commits use square brackets for the area changed. Use linux style commit messages which are imperative in style. The description should be precise, short and gives rough context in one or two paragraphs.
"""

1. Open a new chat (in a project, or in a worktree, or whatever). Ask What's my git commit style.
2. If not in a project, codex starts searching for some style. It doesn't seem to load config.toml

1. If in a project, it tries to "guess" the commit style by looking at previous logs

What is the expected behavior?

When I invoke codex from CLI and ask the same question, I get crisp correct answer based on my configuration.
