The CORTEX agent layer is coordinated and includes a RetrievalAgent for Q-value reranking, cross-encoder, and two-level retrieval so that retrieval quality can be improved through layered ranking logic.

**CORTEX Agents:** Coordinated agent layer — RetrievalAgent (Q-value reranking, cross-encoder, two-level retrieval), LearningAgent (TEMPR memory), AmbientAgent (proactive gap detection)
