Report #4795

[architecture] Agent fails to connect related facts stored separately in memory across different sessions or documents

Augment vector memory with a Knowledge Graph \(GraphRAG\). Store entities and relationships as nodes/edges, allowing the agent to traverse multi-hop paths rather than relying solely on semantic similarity search.

Journey Context:
Vector stores excel at finding topically similar documents but fail at relational queries \(e.g., 'Which of my friends worked at the same company as my brother?'\). Pure vector retrieval requires the answer to be co-located in a single chunk. Adding a graph layer allows the agent to hop between entities, bridging the gap between disconnected but related memories.
