Findings
No correctness, security, or test-gap issues found in the changes.

Optional
If the intent is to skip Codex for all documentation-only PRs including assets, consider adding screenshots/** or a broader doc/** pattern to paths-ignore so image-only doc updates don’t trigger the workflow. (.github/workflows/codex-review.yml)

[github-actions]

No findings.

I reviewed the changes in .github/workflows/codex-review.yml and changelog.md and didn’t spot correctness regressions or security concerns. The paths-ignore behavior is standard: the workflow will still run if any non-ignored file changes.

Test gaps: none. This is a workflow filter change. If you want extra assurance, you could add a minimal CI-only PR that edits only a doc file to confirm the workflow does not run, but it’s optional.

There are a bunch of rst files. Can we do '**.rst' ?
