Report #10555

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

Use a graph-based memory \(Knowledge Graph\) alongside vector stores, linking entities to enable multi-hop traversal rather than relying solely on isolated vector similarity.

Journey Context:
Vector databases excel at semantic similarity but fail at relational reasoning. If Fact A \('Alice works for Acme'\) and Fact B \('Acme uses AWS'\) are stored as separate embeddings, a query for 'Where does Alice's company host?' won't match both via simple vector search. A hybrid approach \(GraphRAG\) stores the entities and relationships as nodes/edges, allowing the agent to traverse from Alice to Acme to AWS, solving the multi-hop retrieval problem that pure vector stores cannot.
