[frontier] Naive RAG retrieves outdated facts and fails to reason about how knowledge evolves over time or track entity changes

Adopt GraphRAG with temporal versioning, storing entities as time-series nodes with bitemporal edges and using temporal Cypher queries to retrieve facts valid at specific timepoints

Journey Context:
Standard vector RAG treats knowledge as static. Leading implementations now use knowledge graphs with temporal edges \(valid\_from, valid\_to timestamps\) and bitemporal modeling \(assertion time vs valid time\). When retrieving context, agents issue time-bounded queries to get the state of the world as it existed at a specific moment, enabling reasoning about entity evolution, retracted facts, and temporal causality. This is critical for financial or medical agents where facts change and reasoning across time is required. Microsoft GraphRAG is being extended with temporal extensions.
