K07 · evidence-bundled critical-infrastructure assurance
Supplier and product due diligence
Direct answer
Supplier and product due diligence provides bounded component or provenance evidence and must be combined with authenticity, installed-state, vulnerability, custody, and recovery evidence.
Authority and evidence boundary. K07 publishes knowledge architecture, bounded reference records, procurement structures, local validation tools, signed synthetic fixtures, and point-in-time source review. It does not certify a facility, award a contract, authorize an operation, prove truth, establish deployment, or claim current operation.

Inventory, signature, attestation, supplier status, vulnerability status, and installed configuration remain separate evidence properties. This record does not certify a product or prove that a deployed asset matches its declared bill of materials.
