Lifted Payments Payment Statement Audit Model

A processor-neutral, machine-readable model for normalizing monthly merchant payment-processing statements without storing cardholder data. Package 1.1.7 preserves the schema 1.1.0 record contract. 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, seventeen deliberately invalid vectors, a reproducible validation report, exact dependency pins, SHA-256 inventory, public threat model, and fail-closed publication gate. Version 1.1.7 verifies Kaggle's unique latest public Ready version from its immutable version history even when the anonymous top-level current-version pointer is stale. It requires that version's human page to contain the exact package version, DOI, source release, and archive SHA-256, then verifies the intact archive or every platform-expanded path and byte. It rejects malformed, duplicate, non-Ready, superseded, extra, missing, case-colliding, unsafe, oversized, or corrupt records and files. The exact merge passed 95 tests and 71 subtests, package gate 15/15, and tagged candidate gate 16/16. Ruff, compileall, Gitleaks, and pip-audit passed; Bandit reported zero medium or high findings. 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.
