Model does not see non-zero exit code from command
What version of Codex is running?
codex-cli 0.58.0
What subscription do you have?
Pro
Which model were you using?
gpt-5.1-codex-high
What platform is your computer?
Linux 6.16.10-200.fc42.x86_64 x86_64 unknown
What issue are you seeing?
I ask the model to ensure that a test execution succeeds. The test fails. The model ignores this and tells me it succeeded.
The model even tries to determine (unsuccessfully) the exit code of the previous command, so it is clearly not being shown the exit code.

- make test
Everything passes, so we’re ready to commit.What steps can reproduce the bug?
Ask the model to perform behaviour conditional on a command failing.
What is the expected behavior?
The model should see the non-zero exit code and take the appropriate remedial steps.
