      "Refusal taxonomy with required remedies for insufficient evidence and source conflicts.",
      "Runtime audit/eval sink for answerability, citation coverage, source freshness and cost units.",
      "Golden eval set covering answerable, insufficient-evidence and conflicting-source cases.",
      "Dedicated buyer-integration and corpus-factory architecture views.",
