[architecture] Agent fails to connect related facts across different memory chunks

Store memories as a knowledge graph \(entities and relations\) alongside vector embeddings, or use an iterative retrieval loop where the agent uses the output of one retrieval as the query for the next.

Journey Context:
Vector similarity is strictly local—it finds chunks similar to the query. It cannot traverse relationships. Pure vector RAG fails at multi-hop reasoning. Graph RAG allows traversal but requires an extraction step. An iterative retrieval loop is a lighter-weight alternative that works with existing vector stores, though it increases latency per hop.
