Yet interoperability does not guarantee factual accuracy or operational use. Collection tools may disagree about components and dependency paths. A valid document may describe source code but not the released binary, the approved architecture but not the running deployment, or direct permissions but not transitive authority.
This is why CIO sponsorship matters. Evidence arrives from product engineering, cloud platforms, suppliers, identity teams, AI governance and managed-service providers on different schedules. The CIO can establish the contract across those boundaries: which subjects need evidence, which identifiers are authoritative, how quickly records must refresh, which signatures are trusted and which differences require a decision.
Procurement should use the same contract. Suppliers should state which profiles they support, how evidence is generated, how often it changes, what is withheld and how vulnerability and lifecycle updates are communicated. A material change to a component, cryptographic dependency, model, service or remote-access path should trigger notice, not wait for an annual review.
