 # 单测试环境数据库空库初始化
 
+排车单号使用`PCyyyyMMdd0001`，日期取`Asia/Shanghai`，全平台跨客户/仓库共用独立日流水。`ll_dispatch_daily_sequence`同步Lastleg源基线与海外空库基线；已有结构的定向新增入口为`lastleg-dispatch-daily-sequence.sql`，只建序列表，不改已有业务号、不回填历史、不重放空库初始化。源码和DDL须配套发布；文件存在不表示已执行或部署。流水在独立短事务分配，回滚或取消不复用，四位范围每日0001至9999，准确单量以主单统计为准。
+
 自有业务运营视图的结构在 Lastleg 源基线及海外统一空库基线新增四张附加表：`ll_fleet_owned_business_ownership/record/command/history`，分别保存原排车装车完成时的车辆归属证据、运营信息、命令与不可变历史；不新增排车主单或第二套运输状态。权限为 IAM `lastleg-permissions.sql` 中的自有业务 list/edit/upload，并同步国内统一空库基线。业务唯一规则见工作区 `docs/海外仓业务/自有业务首版开发契约.md`。本次仅准备源码基线，无 SQL 执行、存量回填或部署；旧已装车 TEST 数据不倒推历史归属，匹配版本按新原生样本验收。
 
 客户计费重独立确认新增 `fl_chargeable_weight_confirmation`，源表与国内空库基线同步；存量 TEST 使用 `migrations/cn/baiyue_firstleg/V8__chargeable_weight_confirmation.sql`，不回填费用确认。须随 Firstleg、Order、Lastleg、Admin 和 Client 匹配版本核对；本次未执行 SQL、未部署。
