Report #81625

[architecture] Agent fails to answer questions requiring connecting multiple disparate facts across sessions

Store memories as a knowledge graph \(entities \+ relations\) alongside vector embeddings, enabling multi-hop traversal rather than just single-hop semantic similarity.

Journey Context:
Vector DBs are great for single-hop 'find similar text', but terrible for 'find the manager of the person who worked on Project X'. Graph RAG or structured memory allows the agent to traverse relationships step-by-step. Tradeoff: KGs are harder to maintain and require reliable entity extraction, but they prevent the LLM from hallucinating connections that aren't explicitly structured in the data.
