Report #8974

[architecture] Agent fails to answer questions requiring multi-hop reasoning because vector search only retrieves local chunks, not connected facts

Implement iterative retrieval \(e.g., ReAct pattern for search\) or graph traversal \(GraphRAG\), where the result of the first search informs the query of the second search.

Journey Context:
A user asks 'Who was the lead architect of the project that replaced the old database?'. A single vector search might find 'We replaced the old database with Neo4j' but miss 'Alice is the lead architect of Neo4j'. Naive RAG fails here. The agent needs to either traverse a knowledge graph or perform multi-step retrieval: find the replacement project, then search for its architect. The tradeoff is increased latency and LLM calls, but it is the only way to solve complex, distributed knowledge queries.
