It never executes payment and exposes no PROCESSOR transition, redemption or reporting action.

Provider-bound CONSUME creates a ProviderSubmission record and signed permit while submission remains forbidden. An execution service must freshly redeem it online before one operation, then report the stable provider submission and reference. The caller report or webhook is only a hint; configured Stripe API or canonical x402 chain verification must independently confirm a terminal outcome before autonomous COMMIT or RELEASE. Offline verification never grants, and provider adoption is not claimed.",
