Codex Cloud not able to create automatic PRs

The useful threshold probably is not “can it auto-open a PR?” It is “what proof exists before a PR gets opened?” The safer path is usually: changes made, verifier passed, blocker state is clean, and the run leaves a receipt that explains why it thinks the branch is ready. If any of those are missing, I would rather see a draft-ready state than an automatic PR. That keeps the automation useful without turning PR creation into another blind loop.
