PYRANA's CORTEX agent layer includes a RetrievalAgent, LearningAgent, and AmbientAgent that coordinate via a message bus to provide proactive, continuously improving knowledge retrieval.

CORTEX agents operate as a coordinated layer above the storage backends. The RetrievalAgent handles query execution and reranking, the LearningAgent maintains Q-value feedback loops, and the AmbientAgent proactively detects knowledge gaps.
