Report #11303

[architecture] Agent fails to connect related facts across different memories

Implement iterative retrieval \(multi-hop\): use the initial retrieval results to generate a secondary search query, traversing the memory store multiple times before synthesizing the answer, or use a Knowledge Graph instead of a flat vector store.

Journey Context:
Single-hop vector search fails for compositional questions \(e.g., 'Who was the manager of the project that failed yesterday?'\). The agent needs to find 'failed project' then use that to find 'manager'. Without multi-hop, the agent either hallucinates or fails. Graph-based memory \(like GraphRAG\) or iterative vector queries are required to resolve multi-hop dependencies, as embedding vectors flatten relationships and lose relational topology.
