Lifted Payments Payment Statement Audit Model

A processor-neutral, machine-readable model for normalizing monthly merchant payment-processing statements without storing cardholder data. The release includes a JSON Schema Draft 2020-12 contract, a Decimal-safe Python validator, a CSV template, a synthetic example, exact field definitions, registered valid and deliberately invalid test vectors, a reproducible validation report, exact dependency pins, a SHA-256 inventory, a public threat model, and a fail-closed publication gate. The model and gate are normalization, integrity, and declared-provenance aids. They are not an accounting opinion, legal review, interchange-pricing guarantee, malware sandbox, qualification determination, price quote, digital signature, or guarantee of savings. Automated screening cannot prove arbitrary notes contain no confidential information; human review remains required before public release. No real merchant or cardholder data is included.
