Report #62298

[architecture] Single-pass vector retrieval misses multi-hop relational facts

Implement iterative retrieval \(e.g., ReAct-style memory retrieval\). Retrieve initial facts, extract entities, use entities to query a graph or vector DB for the next hop, and synthesize.

Journey Context:
If a fact is 'User A lives in City B, City B has policy C', a query about 'Does policy C apply to User A?' will fail in flat vector search because the embedding for User A and Policy C might be distant. Graph-based memory or multi-hop RAG is required for transitive reasoning across disconnected nodes.
