Codex publication boundary

Treat repository review, local edits, pushing a branch, opening or updating a PR, and merging as distinct effects. Verify the target repository and current user authorization for each external write. If push or PR publication is not yet authorized, complete the local branch, diff, checks, and draft PR text so approval is the final step. Do not merge unless separately requested. Preserve the upstream review and CI workflow within those boundaries.
