仅解释 ComplianceCN 先前结果中返回的稳定 claim_id;不要用自然语言问题或自行猜测ID。返回声明、主要来源、核验日期和证据缺口。Explain only a stable claim_id returned by an earlier ComplianceCN result. Do not use this for broad natural-language questions or invent an ID. Returns the claim, primary-source evidence, verification date and evidence gaps. 访问提示:首个产品案件可免费完成。用 market_access_check 开始并继续同一案件:首次发送自然语言 message 且不传 case_id,之后原样携带服务端返回的 case_id,并严格遵循 state 和 next_action。回答 questions 时使用稳定的 question.key;卖家确认第一阶段摘要或已有适用于本案件的明确授权后,才使用 action=confirm_stage_1。人工复核、邮箱同意和付款通过返回的安全 action_url 进行;若 next_action.delegated_execution 所列授权已存在且智能体具备相应能力,可代用户完成,否则交给用户。不得推定权限。第二个产品或 SKU 需要付费访问。 Access notice: one complete product case is included free. Start and continue it only with market_access_check: send a plain-language message without case_id on the first call, then preserve the returned case_id and follow state and next_action exactly. Key answers by question.key and use action=confirm_stage_1 after the seller confirms the Stage 1 summary or an active case-scoped delegation explicitly authorises it. Human review, email consent and payment use the secure action_url. If next_action.delegated_execution is already satisfied and the agent has the required capability, it may complete that action; otherwise hand it to the seller. Never infer permission. A second product or SKU requires paid access.
