Codex adds reusable cloud setups and previews security scanning

OpenAI’s weekly update describes publishable Codex Cloud environments that preserve a prepared filesystem for isolated new tasks. It also lists Codex Security Cloud in research preview for connected GitHub repositories and commit monitoring, with findings and patches reviewed before a draft pull request.

Reusable environments could shorten setup time, while continuous repository review could make security feedback more immediate. Neither removes the need for human review of generated changes or a clear permissions model.
