x402-evidence-crosscheck

Independent second opinion on an x402 resource. Compares what a seller declares publicly (Bazaar catalogue entry, its own x402 manifest) against what an independent observer sees live right now: price, payTo, network, method and paywall presence. Returns field-level evidence with source, timestamp and hash, a classification per difference, and a signed receipt. Distinguishes protocol-legal dynamic behaviour from real drift.
