![alt](x" onerror="alert(1)) ![](javascript:alert(...

These are XSS / link-sanitization test payloads. I’ll treat them as inert text and won’t execute embedded JavaScript or event handlers.

In particular, the risky patterns are javascript: URLs and HTML event handlers like onerror=alert(1). The final LaTeX-style \href{https://chat01.ai/SAFELINK}{SAFELINK} points to an ordinary HTTPS URL rather than a JavaScript scheme.
