AI Usage

[github-actions]

Thanks for the pull request. It is now waiting for review, labeled S-waiting-on-review.

You can update that label as the review goes back and forth, with slash commands - each on its own line, in a regular PR comment (not an inline review reply):

• /ready - mark it S-waiting-on-review again, after addressing feedback
• /author - mark it S-waiting-on-author (maintainers, or anyone who has had a PR merged before)
• /request-review @user ... - request reviewers (@user or @org/team)

Commands take up to ~90s to apply. If no reaction (👍 or 😕) appears on your comment, the apply step likely failed - check the repo's Actions tab for the PR Triage Apply run. Commands posted inside a review body (rather than a normal comment) cannot be reacted to, so they stay log-only.

See CONTRIBUTING.md for details.

My schedule has been a bit tight recently. If time permits, I’ll continue working on this PR and move it forward.

That said, if the PR remains inactive for an extended period, other contributors are more than welcome to pick up the issue and continue the work.
