Report #24248

[architecture] Agent fails to answer questions requiring connecting multiple distant memories

Use graph-based memory \(Knowledge Graph\) alongside vector stores, or implement iterative retrieval loops where the agent uses one retrieved fact to query the next.

Journey Context:
Vector DBs are great for single-hop semantic search but fail at relational queries \(e.g., 'Who introduced me to the person who built the project I'm working on?'\). Graph databases handle transitive relationships natively. Combining vectors for semantic matching and graphs for traversal yields robust multi-hop reasoning, preventing the agent from hallucinating connections it cannot retrieve.
