IMPORTANT: read `risk_level`, not `overall_risk_score`, to judge an agent. Scoring presumes risk, so an agent nobody has paid to verify scores 100 exactly like one assessed as dangerous. risk_level separates them: 'not_verified' means unassessed and is NOT a finding against the agent, while 'critical' means verified and genuinely high risk.
