Verdict
🟢 GREEN — Score: 78/100
Per-user instance of a verified, legitimate platform. All endpoints live, rich metadata, real ZK technology stack. Slight deduction for per-user account having no direct activity (expected architecture) and for being a templated registration rather than a unique agent.
