Summary\nAdd a lightweight, file-based Codex review setup for pull requests in policyengine-us-data.\n\nGoal\nUse repository files to steer Codex PR review toward:\n- obvious bugs and regressions\n- staged PR boundary checks\n- test coverage gaps\n- explicit severity and confidence classification\n\nScope\nThis is documentation and review-instruction setup only. It should not change production code, test behavior, or CI behavior.\n\nNotes\nThis is expected to be experimental. We may need to bolster, modify, or remove parts of it depending on token usage, review quality, and how Codex behaves in practice.
