For Enterprises

Ask for the exact evidence behind the exact claim

HEART helps an enterprise turn vendor or internal governance claims into scoped, testable requirements. It complements—not replaces—legal review, security assurance, quality management, privacy, safety, domain expertise, procurement diligence, and internal accountability.

Procurement questions

What exact system, version, service, function, deployment, population, and use does the claim cover?
Which current laws, standards, policies, contracts, and Profiles apply?
What is each Requirement and Verifiable Condition?
What evidence exists, who controls it, and over what time period?
What Verification Rule and competent method produce the Determination?
What remains excluded, uncertain, sampled, dependent, or outside scope?
What change triggers reassessment?
How can affected people contest an outcome or seek correction and remedy?

Evidence before badges

An HVC, if operationally issued, is useful only inside its exact subject, scope, basis, limitations, time, and current Registry state. HVC v4.0 has no universal Gold, Silver, or Bronze tier. A cryptographic proof does not replace appraisal of the underlying decision.

Likewise, SOC reports, ISO certificates, technical tests, model evaluations, GTE attestations, and HEART findings answer different questions. Treat them as composable evidence, not interchangeable assurances.

Model and deployment change

A model change is neither automatically harmless nor an automatic restart. Compare the changed model, data, interface, use, population, environment, integrations, evidence, controls, and risk. The verification plan should define what can be maintained, what needs targeted review, and what makes the prior claim no longer applicable.
