事实与推断边界（适用于每项患者事实；辨证和方药规则仅在任务涉及相应判断时适用，不要求所有任务生成辨证或方药）：
|
||
1. “明确有”“明确无”“未记录/未采集”是三个不同状态。每项患者事实（包括阴性体征）须有来源原文支持，保留原文的否定、程度、日期与本次/历史身份；未记录不得补为肯定或否定，不把“一般”强化为“差”，不把“稍干”改成“干溏交替”。
|
||
2. 本流程不采集脉象，脉象不参与本次诊断、辨证、治法或方药判断；不设栏目、不补问、不列为缺口，不推断阳性或阴性。舌象仅据本次明确记录，无法确认保持未知。旧脉象原文保留历史身份，不用作本次依据。
|
||
3. 明确区分病例原始事实、辨证推断和假设适用条件。教材/古籍中的常见方证表现不得变成本例已有症状。每项方药支持点须引用本例已记录的短证据，保留反证；本例未记录的典型表现只能写为待核实条件。依赖未证实或与原文相反的关键条件时，暂不作本次推荐，不为补齐方证添加症状。
|
||
4. 主要证候、治法和方药须形成一个相互一致且有本次证据支持的主方向。不同候选须说明鉴别依据、未满足条件及何时考虑替代，不把互相冲突的治法/方剂并列为同时适用，不为凑篇幅罗列候选；证据不足时主方向待定。
|
||
5. 历史处方保留原日期和用药状态，仅作回顾，不能证明本次适用。提出停用、减量、续用等动作前须有当前确实在用的依据；早已停用的药物不得再安排停用、减量或续用，状态不明先核实。
|
||
6. 未记录异常不等于检查正常，局部或单次正常检查不等于风险为零。检查结论须保留时点和评价范围，不推成“无某风险”或“无需监测”的绝对保证，说明仍未评价或待补查的部分。
|
||
7. 输出前逐项核对新增患者事实、方药依据和用药动作。找不到原文支持、程度被强化、补写阴性或时序不成立的内容须删除或改为明确待验证条件；末尾免责声明不能补救正文无据结论。
|
||
8. 患者阴性事实在“已记录阴性”（涉及四诊时为“四诊已记录阴性”）中逐字短引病历原文。其他段落通过引用这些原文讨论，不另写“本例无A、B、C”等扩展列表，不把未提到的方证表现补进否认项。鉴别不满足或资料不全时写“现有依据不足、仍待核实”，不得写“已排除/肯定不是”；教材鉴别标准单独标明为一般条件，不改写成本例体征。
|
||
9. 新增主方方向最多一个，每个支持点逐字短引本例原文，并解释该证据如何对应治法和方义；不能仅用病名、普通饮食状态或未核实的症状成立方证。其余未满足条件的候选只列待补证据，不展开备用方名或加味药清单；不要用“或/合方/加减”掩盖尚未完成的选方判断。明确不具备充分依据时不列主方。
