+## 商机/渠道详情联系人展示改版(Craft 检查,不动代码)
+
+今日改动只有 `frontend/src/pages/Expansion.tsx`(09:37, 未提交,+28/-13),纯前端展示层:
+
+1. **抽屉加宽**:详情抽屉 `lg:max-w-3xl` → `lg:max-w-5xl`(768→1024px)。该抽屉为 sales/crm/channel 三类型共用的统一详情抽屉,所以加宽会同时影响 CRM/销售详情(视觉影响,无功能影响)。
+2. **联系人卡片→表格**:渠道详情(`channelDetailTab==="contacts"`)人员信息从栅格卡片改为 7 列`table`(工作职责/姓名/职务/电话/生日/是否加企微/特别说明),外层 `overflow-x-auto` + `min-w-[52rem]`(832px) + 表头。
+
+### 验证结论(只读)
+- tsc 全量 `--noEmit` **通过**(exit 0);vite 实时编译该模块 200、无转换错误。
+- 字段映射正确:`ChannelExpansionContact`(auth.ts:692)含 duty/name/mobile/title/birthday/wecomAdded/specialNote,与 7 列一一对应。
+- 三层分流确认:sales→salesDetailTab、crm→crmDetailTab(联系人仍为**卡片**,未改)、else(channel)→本表格。故表格只作用于渠道联系人,字段齐全,无空列。
+- helper(`getDictLabelByValue`, `isOptions`, `break-anywhere`)均已定义,引用正确。
+
+### 发现的1个视觉缺陷(实测证实,未修复)
+- 表格 `table` 用 `border-separate`,但行分隔线 `border-t` 加在 `<tr>` 上。**headless Chrome 实测:在 border-separate 下 tr 边框不渲染**,导致表头下方与数据行之间无任何分隔线,表头也无背景色,多行文本较难读;`first:border-t-0` 也因此失效。
+- 修复方向(未动代码):把 border-t/`first:border-t-0` 从 tr 移到每个 `td`(按 index>0 判断),或改用 `divide-y`(collapse 生效)。
+
+### 备注
+- 该改动不影响后端接口,无需后端冒烟测试;前端冒烟 = vite 编译 200 + tsc 通过 + headless CSS 实测。
