[frontier] How to replace naive vector similarity with structured reasoning over domain knowledge?

Use Knowledge Graphs \(entities/relations\) as the primary retrieval layer; agents navigate via graph traversal \(BFS/DFS\) to find multi-hop relationships, using LLM to generate Cypher/GQL queries.

Journey Context:
Vector RAG fails on 'compare X and Y' or 'find the common supplier' queries requiring joins across documents. GraphRAG indexes documents into entity graphs enabling structured traversal. Tradeoff: indexing cost and schema rigidity vs. reasoning power. This is becoming the default for 'deep research' agents replacing simple chunk-similarity.
