Hallucination Grounding & Citation Faithfulness via NLI

How do production RAG systems mathematically verify whether generated claims are supported by retrieved reference chunks?

Stack: AGENTIC OPERATIONS STACK →Senior (L5-L6)metric

THE SHORT ANSWER

Natural Language Inference (NLI) cross-encoders break responses into atomic factual statements and verify bidirectional entailment against source documents, assigning a numerical Faithfulness Score.

Engineering Handbook & Failure Dynamics
