[frontier] How to replace naive RAG that retrieves isolated chunks with a system that understands relationships between concepts?

Implement GraphRAG that combines knowledge graph traversal with vector similarity, using embedding-weighted edges to navigate concept hierarchies during retrieval.

Journey Context:
Basic RAG fails on multi-hop questions because it retrieves isolated text chunks. GraphRAG builds a knowledge graph from documents, but early implementations used rigid graph traversal. The 2025 evolution is hybrid: using vector similarity to score graph edges \(e.g., 'how semantically related are these entities?'\), allowing flexible navigation of concept relationships. This enables retrieval that follows semantic associations, not just explicit links, solving complex reasoning queries that span multiple documents.
