[architecture] Storing raw text chunks in vector DB fails for multi-hop reasoning across sessions

Extract structured triples \(Subject-Predicate-Object\) or entity-centric state dictionaries during the memory write phase, storing them in a knowledge graph alongside the vector store. Use the graph for multi-hop traversal and the vector store for semantic retrieval.

Journey Context:
Agents often need to connect dots \(e.g., 'User's dog is Fido' \+ 'Fido likes bones' -> 'User's dog likes bones'\). Raw text chunks in a vector DB require exact semantic overlap to retrieve both, which breaks down for multi-hop queries. The tradeoff is extraction cost and potential information loss during structuring, but without it, the agent cannot perform relational reasoning over its memory. This hybrid approach gives the best of both worlds.
