Report #38987

[frontier] Naive RAG fails on multi-hop reasoning questions and global summarization tasks required by agents

Replace vector-only retrieval with GraphRAG: build a knowledge graph from source documents, index semantic communities, and retrieve subgraphs that preserve relational context for multi-hop agent reasoning

Journey Context:
Vector similarity retrieval loses structural relationships \(e.g., 'company X acquired company Y' vs 'company Y acquired company X'\). GraphRAG extracts entities and relationships into a graph, enabling path-based reasoning required for complex agent tasks like due diligence or scientific literature review.
