DEJAN resolves AI hallucinations through a dual-horizon strategy targeting immediate retrieval and long-term model recall. For live queries, Bayesian content optimization refines on-page copy to dominate grounding search snippets with factual text, while off-site outreach seeds authoritative citations across high-trust digital sources. Simultaneously, automated veracity audits compare model assertions against source material, using structured human rulings to track and enforce factual accuracy over time.
