Report #15801

[architecture] Agent cannot answer questions requiring joining information across multiple disparate code modules

Use graph-based memory \(knowledge graph\) alongside vector stores. Perform vector search to find seed nodes, then traverse the graph edges to gather multi-hop context.

Journey Context:
Vector DBs return top-k independent chunks. If the answer requires 'Who is the manager of the author of file X?', vector search fails because the chunk containing the author and the chunk containing the manager might not be similar enough to both appear in top-k. Graph RAG solves this by structuring relationships explicitly.
