Report #39726

[frontier] Why does my agent lose track of complex relationships across documents?

Implement GraphRAG \(Microsoft\): build a knowledge graph from source documents using LLM-extracted entities and relationships, then use graph traversal \+ vector similarity for retrieval.

Journey Context:
Flat vector search misses multi-hop relationships \(e.g., 'Alice's brother's company'\). GraphRAG constructs community summaries and entity graphs. Tradeoff: significantly higher index construction cost \(entity extraction is expensive\) and storage requirements, but enables reasoning over connected data that vector DBs cannot surface.
