Product boundary
The API returns technical evidence of stated integrity checks. It does not establish event truth, legal authority, financial safety or a recommendation. IntegrityPhase is not a qualified trust service; where the function falls within eIDAS, it is offered only on a non-qualified basis and carries no qualified-service presumptions.
The company and applicable VAT status are checked using the required sources. Agent authority is declared: we do not independently verify the representative or whether the company granted the delegation. The signature binds scope, limits and validity. Revocation is permanent. Purchases require current common business and transaction-tax qualification and a separate sales release.
For Logistics, Warehouse Management, Supply Chain and MRO, an agent receives an order-acceptance, parts-reservation or inventory-update message and buys a signed receipt of HMAC, format and freshness checks. IntegrityPhase is not a warehouse system, confirmation of physical stock or fulfilment, or settlement of another business transaction. The receipt does not prove the real-world event.
