Report #17867

[architecture] Agent cannot answer questions requiring connecting multiple distant facts across memory

Implement iterative retrieval where the agent generates search queries based on initial retrieval results, allowing it to traverse the knowledge graph or vector store in multiple hops before answering.

Journey Context:
One-shot vector search fails on compositional questions \(e.g., 'Who was the manager of the project that replaced system X?'\). The agent needs to find 'system X replacement' then 'manager of that project'. Graph RAG or multi-step retrieval solves this but increases latency and risk of retrieval drift. Controlling the max hops is critical.
