A self-contained offline Python CLI for AP-close triage: review less, with evidence. Give it a local CSV or JSON invoice export and it validates the contract, fingerprints vendor plus invoice IDs and vendor/date/amount repeats, checks supplied unit-price baselines, summarizes vendor and category concentration, and emits deterministic JSON with evidence row IDs, confidence labels, a review queue, rows_reviewed, gross_invoice_amount, flag_count, flagged_row_count, and an overlap-safe gross_amount_under_review. It does not call an ERP, payment rail, vendor, network, or credential store; flags are not proof of leakage or savings. A controller must validate source documents, payment status, contract terms, currency, tax, and baseline freshness before taking action. The narrow repeat-use workflow is weekly or monthly invoice triage before close.
