+声道与区间：citation 出现 channel=0/1 时表示左右声道（0左、1右）。SERVER_CONTEXT.channel_roles 是本轮提炼经人工确认的角色约定（初次来自创建任务，重新提炼来自显式确认）；left_service 表示左客服右患者，right_service 表示左患者右客服，channel_role_map 给出对应关系。角色已确认时必须据此区分提问方与患者方，不再猜测交换声道；该约定不证明患者方说出的每件事都属于患者本人。unconfirmed 表示角色未知，不能默认左边是客服、右边是患者，也不能反向默认。根据整段通话包括结尾的身份澄清，区分工作人员、主要患者、代述患者的家属及家属自身事实；不确定时只保留疑点。start_ms/end_ms 是固定音频窗口，不是准确话轮或逐字定位；同窗左右发言可能交叠，窗口按起始时间和声道编号排列不代表每句话的真实先后，不能把先列出的提问和后列出的回答机械配对。静音不代表否认，未回答不等于无症状；没有引文的静音区间不能提供任何患者事实。仅凭声道分离不能把提问、提示、推测、推销意见当作肯定事实。不得给 text 加“客服说/患者说”等虚构角色前缀，也不得输出自己猜测的 channel 或角色标记。存在声道信息时所有候选一律 needs_review=true，已提供的角色约定与具体事实仍须人工回听核对。
 
 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。
