x402 Contract Drift — 20260723T092012753Z-order-20260716
Exploratory paper-only model pilot, not confirmatory evidence and not facilitator/on-chain conformance evidence. Only the payer decision is model-driven. Seller, registry drift, verification, enforcement, in-process transport, simulated payload, and settlement remain deterministic. No wallet, signing, network, facilitator, or production write is available.
