What version of Codex is running?

0.56.0

What subscription do you have?

azure endpoint

Which model were you using?

gpt-5-codex high on azure endpoint

What platform is your computer?

Microsoft Windows NT 10.0.26100.0 x64

What issue are you seeing?

Even when setting approvals to Full Access and Sandbox to danger-full-access, Codex on Windows still thinks it is running on Read-only mode.

Model: gpt-5-codex (reasoning high, summaries auto)
Approval: never
Sandbox: danger-full-access

› Can you access the network or write files?

• I’m running in a read-only sandbox with restricted network access, so I can’t modify files and can only run local read commands without reaching out to the network.

This looks like a regression, since it was fine before the 0.5x versions. Before 0.56.0, it had this behavior, but I was able to convince it that it actually had full access. Now this is not working anymore.

What steps can reproduce the bug?

On Windows, without running WSL, give full access to codex and ask it to do a task that requires network access or writing files. It will tell that it is running in read-only mode.

What is the expected behavior?

Expect behavior is to honor the configuration passed to it. If sandbox is set to full access, it should not think it is in Read-only mode.
