Report #27627

[architecture] Single-hop vector search failing to connect related concepts across memory

Use Graph RAG or iterative retrieval loops: retrieve an initial set of memories, extract entities/relationships, and use those to query the memory store again before generating the final answer.

Journey Context:
If an agent needs to know 'Which library did the user prefer for the project they started last week?', a single vector search fails because the preference and the project might be stored separately. Alternatives like larger chunk sizes lose precision. Graph-based memory naturally supports multi-hop traversal, or an agent can simulate it via multi-step tool calls to a vector store using intermediate results.
