The paper analyzes how communication network topology in multi-agent LLM diagnostic systems affects semantic drift. Using Bio_ClinicalBERT embeddings across Barabási-Albert, Watts-Strogatz, and Erdős-Rényi network models, it finds hub-centric architectures amplify hallucinations, causing 53.29% cosine similarity degradation. It proposes spectral monitoring with algebraic connectivity bounds for topological stability.

Quantifies how multi-agent LLM network topology degrades diagnostic accuracy — hub-centric designs amplify hallucinations rather than containing them. The spectral monitoring and algebraic connectivity bound method is directly applicable to multi-agent system design.
