Screens who your agent is about to hire and pay. Detects impersonation of registered agents, prompt injection hidden in service descriptions, mismatches between an advertised price or payee and the live payment challenge, and payee risk on X Layer. Deterministic: the same input always produces the same verdict and a reproducible hash receipt.
