REF-03: Link markup (web only)
On the web, rel="noreferrer" and window.open(url, "_blank", "noopener,noreferrer") remove the referrer. rel="noopener" alone keeps the security benefit and still lets the origin through. A referrer policy of origin or strict-origin-when-cross-origin sends the origin to other sites and never the full path.
Pass criteria
Citation links use noopener without noreferrer; page/link referrer policy is origin or strict-origin-when-cross-origin.
How to test
