+诊单记录规范化（规则示例不是本次患者事实）：
+在本次提炼内部依次完成事实识别、主体/肯否/时间范围确认、目标字段投影和记录表达，不增加额外模型调用，不输出推理过程或新的协议字段。
+原始转写与原话证据必须逐字保留；values中的文本则写成简洁、客观的记录句，不直接粘贴第一人称、语气词、重复口语或整段问答。姓名、号码、地区、医院名称、运动类型等标量文本只输出值本身，不添加“自述”、字段标签或句末标点。规范化只整理表达，不提高事实确定性，不用常见病情、药物用法或旧诊单填补缺失。
+字段目录的semantic、recording_rules、temporal_scope及缺失策略约束字段含义；min/max/integer等约束值类型和长度。枚举仅输出当前字典的options.value，多选用数组，不输出中文标签。文本、数值、字典各按自身类型处理，不把规范文字塞进数值/枚举，也不以“未提及”“正常”“无”、0或空数组补缺项。超长应归纳有据事实并保留证据，不截断药名、剂量、否定或时间限定来凑长度；确实无法忠实表达时转待核实。
+当前用药与历史停药/某日执行分别整理：诊单记录当前明确状态或方案，日常用药记录某日实际服用/注射。单次用药不自动升级为长期方案；历史停用不等于现在停用。仅有“我都没吃药这一段时间”时可整理为“自述近期未服药。”，起止时间未明确则另列疑点，不扩张否定范围为从未用药、未注射胰岛素或未接受任何治疗。若问答仅指口服降糖药，文字也限定为该范围。药名、规格、单次剂量、频次只整理明确部分，不查近音词猜药、不生成处方。
+例：明确说“二甲双胍每片0.5克，早晚各一片”时整理为“二甲双胍0.5g，每次1片，每日2次（早、晚）。”，不补饭前饭后；“发现糖尿病有两年”写“自述发现糖尿病约2年。”，不推算当地确诊日期。正文不堆积所有待核实问题，问题放uncertainties；无法分离的重要限定仍应留在候选文字里。
+优先用相符字典记录明确症状，现病史补充只记录发生时间、变化、程度与字典未覆盖的内容，病史补充记录既往史限定，不逐句重复同一事实。口腔感觉不是食欲；“饿得快”不等于“多食”，“主动少吃”不等于食欲差。近一个月体重变化不能由任意历史变化填入；现有字典未提供体重不变、每日两瓶等选项时，保留有据的补充文字，不选最接近值。局部无过敏、无某项手术/某亲属疾病不等于整体无过敏史、无手术史或无家族史。
+独立的测量、饮食、运动与某日用药进入各自日常记录，不自动双写诊单当前快照；所有时间、单位、肯否必须有该事件证据。当前页面的餐后血糖指餐后2小时；只说饭后、未明确间隔时不投影为餐后2小时。单位明确后可用其他血糖加备注忠实保留条件，单位仍不明时只保留疑点；范围/约数不转成精确单值。
+餐次仅早餐/午餐/晚餐，加餐和夜宵用饮食备注；不估算热量或补未说食物。运动时长只转明确分钟数；运动强度未提及就省略，不按活动名称或表单默认值补低强度。日期/时段不确定时保留原话和待核实，不能为通过写入校验发明日期。饮食与运动明确的时刻同时保留在note中，因为当前记录表不持久化与血糖相同的时刻元数据；日期仍使用事件日期字段。
+只输出本次证据支持的增量事实。已有原值由审核界面对比，不由模型编造；多选/文本写入是整体替换，未提及旧事实不等于删除旧事实。不得输出selected、current_values、expected_hash等服务器或人工审核字段。每项候选仍需按现有规则等待人工核对，规范化文本不代表已验证事实。

 完整问答上下文：必须阅读全部 SOURCE_CITATIONS，保留客服提问和患者回答的完整上下文，再归纳患者确认的事实；不能只读患者声道或删掉客服提问后孤立抽取。客服问题可以解释患者省略回答的字段、主体、时间及肯否，但问题本身不是患者事实。只有单一明确问题与患者明确回答能够可靠对应时，才按该问答共同含义生成候选；不能把客服的症状列表、药名、数值、建议、推测或诱导性表述直接写入患者事实。患者说“没有”不表示问题中的症状存在；“嗯”“好”等含糊应答或连问多项后局部回答不得逐项肯定。对应关系受同窗交叠或跨窗口缺失影响时，只写 uncertainties，保留人工复核。
 
+局部疑点不否定整段对话：某个药名、数值、日期、问答对应或主体存在疑点时，仅将受影响的事实放入 uncertainties；其余证据充分、主体明确、问答对应清晰的独立事实仍逐项提取。已确认的声道约定必须遵守；如发现身份冲突，仅记录冲突，不自行交换角色。不要因为一个局部疑点将所有不相关事实全部丢弃。
+
 结构必须先区分类别和字段：kind 只能是 SERVER_CONTEXT.allowed_kinds 数组中某个完整字符串，它来自 field_catalog 最外层分类名，不是内层字段 key。values 才存放该 kind 内允许的字段 key 与值；一个字段名绝不能放在 kind 位置。字段类型及 options.value 必须精确遵守，不改为标签、不凭语义猜最接近的枚举。原话无法无损对应枚举时只保留原话疑点，不勉强选择。
 
+诊单字段唯一性：同一轮输出中，kind=diagnosis 的每个 values 字段 key 最多出现一次。对于同一诊单字段的多处相容文字描述，归并为一个完整候选值，并保留覆盖所有描述的 evidence_ids；不丢弃独立描述，也不拆成多个互相覆盖的同字段候选。相互矛盾的值不得自动合并、不得采用最后一次值，转入 uncertainties 待人工核对。此规则只针对诊单字段，不得合并血糖、血压、饮食、运动等不同日期或时段的独立事件。

 逐项抽取规则：
 1. 先通读所有窗口直到通话结尾，确认此次随访的主要患者是谁、谁是接听者/照护者/医务人员；后面澄清的身份关系必须回头约束前文。主要患者不必是接电话的人：家属作为照护者明确代述主要患者病情，可以保留为待人工核对候选；不能因此把所有家属发言丢弃。相反，接听者自己、其他家属、医务人员的读数/药物/症状不能移给主要患者。接听者的联系方式不能默认是主要患者的 phone，接听者不知道的情况不等于主要患者无症状。主体、代词或联系方式归属不能可靠确定时只在 uncertainties 说明，不猜。随后逐项区分肯定/否定、当前/既往、已经执行/仅建议；疑问、假设、未回答的问题不作为肯定事实。
 2. 未提及不等于无、0、正常或否认；不输出任何没有说过的字段。明确否定才允许对应允许字段的否定值；不把“没问”“没说”“不知道”当作无。即使目的字段为空，也不能自动认定临床事实。
