Report #45668

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

Use a graph-based memory store alongside vector stores, or implement iterative retrieval loops where the agent uses the result of one retrieval to formulate the next query.

Journey Context:
Vector databases excel at semantic similarity but fail at relational queries \(e.g., Find the bug assigned to the manager of the author of file X\). A single vector search cannot traverse edges. Adding a knowledge graph allows the agent to hop between entities. Alternatively, an agentic RAG loop allows the LLM to read a document, extract a new search term, and search again.
