The four-part AI citability standard — abbreviated EAV-E — that determines whether a brand claim is citable by AI systems without triggering hallucination-avoidance behavior. Entity: a named, disambiguated entity. Attribute: a specific, defined property. Value: a verifiable, concrete claim. Evidence: traceable, cross-referenceable proof. A statement like ‘We improve customer outcomes’ fails EAV-E. ‘Company X reduces deployment time to 24 hours, validated by 150 client implementations documented in their 2025 case study library’ passes it. Corroboration campaigns built on content that fails EAV-E will underperform regardless of source tier quality, because the AI’s hallucination-avoidance behavior suppresses citation of imprecisely stated claims. EAV-E compliance is the pre-condition for citation engineering to work as specified.
