Report #24426

[architecture] Agent fails to connect related facts across multiple documents

Implement multi-hop retrieval: first retrieve initial entities/facts, then use those results as new queries to traverse a knowledge graph or perform secondary vector searches, accumulating context over 2-3 hops before synthesis.

Journey Context:
Standard RAG is single-hop: query -> retrieve -> generate. This fails when the answer requires connecting 'Project Alpha's lead' with 'The lead's current timezone'. A single vector query won't bridge these. Multi-hop retrieval mimics human reasoning by chaining searches. The tradeoff is latency and error propagation: each hop adds time and risks retrieving off-topic data that derails the next hop. Limiting to 2-3 hops and using an LLM to guide the intermediate queries mitigates this while preserving the ability to synthesize across disparate data silos.
