agent skills path (spine, review-loop, pr-review, error-fix).
A draft plus local tests is not done. Pull-request done is signed commits on a branch in this repository, grok quality and logic then Codex quality and logic on this head with zero findings, CI green on this head, then ready. The authoring session does not sit those PR reviews. A human merges.
