 /**
  * 国际出港计重-运单详情 ViewModel（5.5寸手机版专属页面）
  *
- * 只读展示计重记录列表传入的运单信息，无接口请求。
- * 注：设计稿中的「通道号」字段在 /IntExpCheckIn/checked/pageQuery 出参中不存在（后端缺口，
- * 见接口问题清单），布局侧空值兜底显示 "-"。
+ * 先展示计重记录列表传入的运单信息；/IntExpCheckIn/checked/pageQuery 出参中
+ * 航班日期/航班号/航程/业务类型/备注恒为空（Bug #622），再按 11 位运单号调
+ * /IntExpCheckIn/queryWbByNo 补齐这些字段（只补空值，不覆盖列表已有数据）。
