The Evidence Path

Adaptive and corrective control

6 of 12 · Control · 8 named systems

Adaptive RAG systems route retrieval effort, grade returned evidence, and escalate only when the current evidence state is insufficient.

Adaptive and corrective control: architecture comparisonEach lane reads from input to output.
