Report #87740

[architecture] Agent fails to connect related facts stored separately across different sessions or documents

Use a knowledge graph \(entity-centric memory\) alongside vector stores to enable multi-hop traversal of related entities, rather than relying solely on semantic similarity search.

Journey Context:
Vector DBs are great for semantic similarity but terrible for relational reasoning \(e.g., 'Who worked with the person who founded X?'\). Pure vector retrieval fails multi-hop queries because the embedding of A doesn't necessarily match the embedding of C, even if A relates to B and B relates to C. GraphRAG or entity-centric memory stores relationships as edges, allowing the agent to traverse nodes and synthesize answers across disconnected data points.
