## Description

* Determining whether vulnerabilities faithfully reproduce the original attack vector and impact
 * Evaluating proposed security fixes and remediation strategies
 * Reviewing test suites that verify both:
 + Normal application functionality remains intact
 + The original exploit no longer succeeds
 * Identifying incomplete fixes and alternative exploitation paths
 * Reviewing Docker environments for correct software versions, services, networking, and configuration
 * Detecting potential regressions or new vulnerabilities introduced by a fix
 * Providing recommendations for improving vulnerability reproductions, fixes, and verification logic
