[frontier] How do I prevent my agent from losing track of complex relationships between entities across long conversations?

Replace flat vector RAG with GraphRAG: at indexing time, extract entities and relationships into a knowledge graph, and at query time, use the agent to traverse the graph \(not just retrieve chunks\) to answer multi-hop questions with provenance.

Journey Context:
Naive RAG retrieves semantically similar chunks, but agents need to reason about 'the company that acquired X, which was founded by Y'. Vector similarity fails on these structural queries. GraphRAG \(Microsoft Research, 2024-2025\) builds a knowledge graph during indexing, then uses community detection and graph traversal at query time. The frontier pattern is integrating GraphRAG as the agent's 'memory' layer: the agent generates Cypher or GQL queries to traverse the graph during its reasoning chain, rather than just retrieving text. This gives agents explicit relationship reasoning and source attribution \(which edge led to this fact\), solving the 'lost in the middle' and 'multi-hop' failure modes of RAG.
