By name: mpp-charge description: Model provider-side charge verification through the MPP settlement family. runx: category: payments
MPP Charge
Compose provider-side charge pricing, challenge emission, credential verification, receipt sealing, and modeled forwarding for the multi-party payment protocol settlement family.
This graph profile records registry and harness shape only. It does not perform live settlement, read rail credentials, or enable runtime forwarding.
Quality Profile
- Purpose: show how MPP provider-side credential verification fits the governed charge graph.
- Audience: operators, registry tooling, and future MPP adapter implementers.
- Artifact contract:
charge_price_packet,charge_challenge_packet,charge_verification_packet,charge_seal, andforwarded_result. - Evidence bar: success requires priced bounds, challenge idempotency, MPP-family proof ref, receipt ref, and modeled forward gate.
- Strategic bar: keep MPP credential material behind references.
- Stop conditions: stop before modeled forwarding when verification lacks a sealed receipt ref.
Inputs
