Chargeback Evidence Bundle Composer

Scope & reliance: 🔒 All inputs are processed locally in your browser. No data is transmitted. Do not enter real personal data: use synthetic or anonymised inputs only. This composes an evidence bundle prepared for a payment-network dispute or adjudication review, mirroring the network guidance that a mandate plus a verifiable payment token together form the evidence record. It is verify-only: nothing here initiates, contests, routes, or settles a chargeback, and producing this bundle does not itself decide or guarantee any dispute outcome. Mandate and payment-protocol evidence steps cite the existing verifier kernels that cover their domain (AP2 mandate-chain validation: art-01; AP2 payment-receipt verification: art-62; x402 payload decode/lint: art-26; A2A x402 extension mandate validation: art-31; x402 batch settlement reconciliation: art-61); this composer does not re-derive their logic, only records evidence of their outputs.
