Pre-Trade Guard — before you pay an x402 listing, screen the payTo you are about to pay: its Verdict Index catalog history (first seen, payTo rotations, listings added or removed across the snapshots held), an OFAC SDN exact-match check, and the wallet's Base age and activity, combined into PROCEED, CAUTION, or ABORT with itemized reasons. Use this when an agent is about to pay a payTo it has never paid before.
