Settlement proof
Settlement evidence, receipt and policy chain in one audit view.
This page turns the Agentic Workflow Demo into a reviewer-ready proof artifact: the x402 receipt, policy decisions, Arc settlement evidence when configured and validation evidence are tied to the same workflow and agent job IDs.

Transaction memo
Business context attached to the payment.
Arc memos make the transaction reconcilable beyond a raw hash: invoice, agent, customer and batch references stay attached to the proof envelope and can be indexed by downstream systems.

Policy pass is not final settlement.
The job can execute after policy approval, but final proof stays review-held until the request hash, single-use nonce, memo reference, receipt digest and validation evidence match the same job envelope.

Policy pass is not final fulfillment
Kestrel separates policy approval from execution evidence. If a job clears policy but the provider receipt or validator artifact does not arrive, the envelope moves into a bounded review state instead of silently becoming a successful settlement.
Policy pass is only a precondition.If execution, receipt or validation evidence is missing, the proof remains review-held and settlement finalization is blocked.

The job may run, but it is not final until fulfillment evidence arrives.Allow execution to startexecution_failedExecution failedIf the provider or tool execution fails after policy approval, the job is isolated for review.Keep funds and reputation unchangedreceipt_missingReceipt missingA missing provider receipt prevents the job from being treated as fulfilled.Hold settlement proofvalidation_missingValidation missingA missing validation artifact prevents reputation from being updated from that run.Block trust updatedispute_openedDispute openedDispute state gives the operator a clear path to retry, refund or manually resolve.Open operator reviewArtifacts
