Report #71381

[frontier] Naive RAG returns disconnected chunks that fail on queries requiring global reasoning across documents

Replace vector-only retrieval with GraphRAG: build a knowledge graph \(entities and relationships\) from source documents, use community detection to generate hierarchical summaries, and retrieve via both specific entity paths and global community summaries for synthesis queries.

Journey Context:
Embedding similarity fails on questions requiring implicit relationship tracing \(e.g., 'how does entity X indirectly influence Y across 50 reports?'\). GraphRAG explicitly models relationships and uses LLM-generated summaries of graph communities to answer global questions that span disconnected text chunks. The tradeoff is higher index build cost, but retrieval quality for complex reasoning tasks is significantly higher.
