 如果确认要清理所有开发 / 测试酒店的旧任务，可去掉上述 SQL 中所有 `hotel_id = @hotel_id` 条件。不要在生产环境执行这种全量清理。

+
+当联调时已明确某个旧 `workflow_reservation_task` 是 V4 Debug EML 误走历史 V2/V3 profile 产生的残留，可按旧 task ID 定点清理。该脚本仍只适用于开发 / 测试环境，不清理 SourceMessage、V4 order task、V4 cards、来源通知、目录、账号权限或酒店配置。
+
+执行前应先从当次排查记录中确认旧 `workflow_reservation_task.id`，只把该 ID 填入 `@legacy_task_id`。Debug run ID、SourceMessage ID 只作为人工核对线索，不写入清理条件，避免误清理来源消息或 V4 数据。

+```sql
+-- 必填：替换为当次排查确认的旧 workflow_reservation_task.id。
+-- 保持 NULL 时下方 SQL 不会命中任何旧任务。
