# x402 Pay Negative Quote Drift Reserve

Emit a deterministic reservation packet for the x402 quote-drift fixture. The
reserved child authority stays a valid subset of the parent and reserves the
quoted `125` minor-unit spend, but the spend capability binding drifts upward to
`175`. Native authority admission must reject the binding before rail
fulfillment can expose mock credential or rail material.
