Report #5317

[architecture] Agent fails to answer questions requiring connecting multiple distinct memories \(multi-hop reasoning\)

Use graph-based memory \(Knowledge Graph\) alongside vector stores. Store entities and relationships as nodes/edges, and use the vector store only for semantic node indexing, traversing the graph for multi-hop queries.

Journey Context:
Vector stores are fundamentally single-hop semantic matches. If the answer requires 'Who is the manager of the person who wrote the backend?', vector search fails because the combined fact doesn't exist as a single chunk. Graph databases natively support multi-hop traversal. The hybrid approach uses vectors to find the entry node and graphs to traverse relationships.
