Lifted Payments Payment Statement Audit Model

A processor-neutral, machine-readable model for normalizing monthly merchant payment-processing statements without storing cardholder data. Package 1.1.1 preserves the schema 1.1.0 record contract and hardens the validator and publication gate. The release includes a JSON Schema Draft 2020-12 contract, Decimal-safe Python validator, CSV template, synthetic example, exact field definitions, two registered valid vectors, fourteen deliberately invalid vectors, a reproducible validation report, exact dependency pins, SHA-256 inventory, public threat model, and fail-closed publication gate. The frozen candidate passed 53 adversarial tests and every one of 11 publication checks; an independent hostile review found no remaining issues. Version 1.1.1 rejects pathological numeric tokens, hostile Decimal contexts, unknown-field path leakage, malformed or non-object metadata, missing or unregistered corpus vectors, traversal and symlink paths, canonical-path aliases, candidate-validator failures, stale reports, checksum drift, and common credential signatures across every declared source asset. This model is a normalization and comparison aid, not an accounting opinion, legal advice, interchange-qualification determination, price quote, 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.
