Cross-agent verification handshake — no proof, no transaction. MIT licensed, 4,244 tests.
56 deterministic fact-checkers in one server (IBAN, VAT, VIN, GTIN/barcodes, national & tax IDs, crypto addresses, phone, dates, holidays) — verify the structured facts an agent emits against checksums and curated data.
