[architecture] Storing memories as isolated chunks in a vector DB, losing entity relationships required for multi-hop reasoning

Complement vector storage with a Knowledge Graph \(GraphRAG\) or entity-centric memory index to traverse relationships \(e.g., A -> works\_for -> B -> acquired\_by -> C\).

Journey Context:
Vector DBs excel at 'find things like X' but fail at 'find the relationship between X and Y'. If an agent needs to answer 'Does the CEO of the company that acquired my startup use our product?', vector search will likely fail because the answer spans multiple disconnected documents/memories. A graph structure allows the agent to traverse known nodes \(Startup -> Acquirer -> CEO -> Product Usage\), making multi-hop deduction reliable and explainable.
