# Credential Interoperability **Domain:** Trust Infrastructure / Certification / Identity **Doc Type:** Concept Node **Maturity:** Developed **Concept Hub:** [[wiki/War With Empire|War With Empire]] ## Definition **Credential interoperability is the portable validity of an institution's attestation across organizational or jurisdictional boundaries.** It asks when one system will recognize another system's authority to certify a proposition about a person, product, process, model, or organization. ## Scope Professional qualifications, product conformity assessments, identity credentials, and AI safety attestations belong to different legal regimes. They share a higher-order structure without becoming interchangeable objects: each depends on rules governing whose proof another system will accept. ## War With Empire Context [[articles/war with empire/The True Enemy of Both China and the United States|The True Enemy of Both China and the United States]] uses credential interoperability to compare recognition across human qualifications and machine certification while preserving their legal differences. The concept exposes recognition as a governance layer above the underlying measurement. ## Key Insight **A credential becomes power when its issuer can make a proposition portable across boundaries.** ## See Also [[wiki/Certification State|Certification State]], [[wiki/Legibility for Participation|Legibility for Participation]], [[wiki/Delegated Verification|Delegated Verification]], [[wiki/Exit-Capable Interoperability|Exit-Capable Interoperability]]
