 - `workbench.alert_events` 保存任务显式推送的事件，`workbench.alerts` 保存当前状态。分析结果、测点值和缺测状态不会自动变成告警。
 - 每个可选分区独立读取并返回 `ready`、`not_configured` 或 `degraded`，一个分区失败不会污染其他分区。
 
-预约任务演示数据由 `scripts/seed_workbench_work_orders.py` 直接写入 `workbench.work_orders`，与外围样板的 synthetic 测试数据相互独立。种子集 `workbench-demo-orders@1` 恢复前端原有的三张 mock 工单，分别覆盖派发、执行和复令状态；脚本会在同一事务中删除旧的“外围合成数据核查”投影并幂等写入新记录。当前固定演示日期为 2026-09-17。外围种子脚本仍可重复执行，并会恢复曾被软删除的固定演示工单和测试数据。
+原有三张独立演示工单已迁入 `peripheral_sample.work_orders`，仍由外围样板面板管理，并由同步器投影为 `external_work_order` 工况任务。旧表退役前的完整数据库备份由部署记录保存，不能重新运行历史 `011_workbench_work_orders.sql` 或旧种子脚本重建双份数据。
