Paid agent-facing brief on Decision procedure for an agent evaluating a real-world-asset (RWA) issuer's x402 payment rai

Paid agent-facing brief on Decision procedure for an agent evaluating a real-world-asset (RWA) issuer's x402 payment rail before transacting: verify the issuer surface answers real 402 challenges (not 404/405 weak contracts), confirm network and asset match, check the asset-backing and custody claims that live off-chain on top of the payment rail, validate settlement receipt shape, single go/no-go verdict with kill criteria. Blunt decision procedure, not marketing.
