contents <p>This paper addresses a fundamental accountability gap in generative AI systems:<br>while generated content leaves an auditable trace, the <em>refusal</em> to generate harmful or illegal content remains externally unverifiable.</p> <p>Current AI logging architectures are output-centric. They allow platforms to demonstrate what was generated, but not to prove—cryptographically and to third parties—that prohibited content was <em>not</em> generated. As a result, platforms can only assert that safeguards existed or that requests were internally blocked, without providing verifiable evidence.</p> <p>This structural weakness was exposed by the January 2026 Grok incident, in which a large-scale generative AI system produced non-consensual intimate imagery while the provider claimed that moderation systems were in place. External parties could verify neither the existence of refusal events nor the completeness or integrity of disclosed logs.</p> <p>To address this gap, the paper proposes <strong>CAP-SRP (Content/Creative AI Profile – Safe Refusal Provenance)</strong>, a cryptographic logging protocol that treats <em>non-generation</em> as a first-class, provable event. CAP-SRP enforces a completeness invariant whereby every generation attempt must have exactly one recorded outcome (generation, refusal, or escalation), linked via cryptographic hash chains and periodically anchored to external timestamping services.</p> <p>This design enables independent verification that:</p> <ul> <li> <p>all generation attempts were recorded,</p> </li> <li> <p>each attempt has a corresponding outcome,</p> </li> <li> <p>logs have not been truncated or forked, and</p> </li> <li> <p>refusal events were not fabricated after the fact.</p> </li> </ul> <p>The paper positions CAP-SRP as a concrete technical implementation of EU AI Act Article 12’s logging requirements, shifting AI governance from trust-based assertions to verification-based accountability.
