 2026-10-20 用户追加整页白底修正：整页主要列表外层workbench-table及整页详情workbench-panel显式增加is-page-surface，由公共样式移除最外圈border/radius/shadow。内部指标、图表、并列卡片、子表格线、弹框和日历左右独立面板保留；本批不改padding、脚本或承载。layoutAcceptance.test.ts仅将旧页头分隔线颜色期望改为当前workbench-border，托盘先于预约及字段列数等布局断言保留。
 
 本次整页面层收口：40个Vue文件仅新增class modifier，逐文件内容对照与差异检查通过；layoutAcceptance.test.ts定向6项通过。文件已固定，公共样式及全量门禁由总控收口，人工视觉仍待截图确认。

+### 2026-10-21 附件预览与尾程列表核对
+
+| 页面/文件 | 操作与既有承载 | 结构问题与修复 | 验收 |
+|---|---|---|---|
+| DispatchEvidenceFiles | DispatchWorkflowDialog内附件预览居中二级弹框 | 原预览挂载在父弹框DOM内；显式append-to-body，隔离父级布局与滚动容器 | 定向回归通过；待人工1920×1080、100%截图确认 |
+| LastMileOrdersView | 尾程订单筛选区 | 用户要求隐藏仓储转运与退货两段长汇总；本批确认两段模板及专用样式未恢复，保留行数据仍使用的统计响应 | 定向回归通过；待人工截图确认 |
+
+本批未修改SmartDispatchDialog及其候选分页、入库计划、换标与退货出库业务逻辑。源码复查这些入口的既有承载与表单/表格布局，未凭推测批量改宽度或删除必要横向滚动。
+
+公共缺口复核：此前AppDialog后代选择器可能连带命中二级弹框；当前公共写者已将header/body/footer改为直接子级选择器，代码层已收口，本域未修改公共样式；真实嵌套预览仍待人工截图确认。
