开发 / 测试环境 V4 旧任务数据清理说明

1. 使用边界

本说明只适用于开发 / 测试环境，用于 M002 V4 主线停止双写旧 workflow_reservation_task 后，清理历史 smoke、fixture 或调试过程中遗留的旧任务数据。

项目当前决策：

V4 后新业务主线只写 V4 模型：workflow_reservation_v4_order_task、workflow_reservation_v4_task_card、workflow_reservation_v4_source_notification。
开发阶段不维护 V2/V3 旧任务兼容，测试数据可重建。
本清理策略不代表生产迁移方案；生产数据迁移必须在上线前单独设计、评审和演练。

2. 不清理的数据

以下数据不要通过本脚本清理：

platform_source_message_inbox
workflow_reservation_v4_order_task
workflow_reservation_v4_task_card
workflow_reservation_v4_source_notification
workflow_reservation_catalog_account
workflow_reservation_catalog_code
用户、角色、权限、菜单和酒店配置表
platform_superagent_dispatch_run
SourceMessage 原始链路和 SuperAgent dispatch 运行记录

3. 清理范围

清理目标为旧任务主模型和直接依赖旧 task 的开发测试数据：

workflow_reservation_opera_operation_attempt
workflow_reservation_opera_operation
workflow_reservation_audit_log 中 task_id 指向旧任务的审计行
workflow_reservation_invoice_generation.task_id 指向旧任务时置空，不删除生成记录
workflow_reservation_task_card
workflow_reservation_task
workflow_reservation_order.created_from_task_id 指向旧任务时置空，不删除订单

workflow_reservation_invoice_generation 可能带可选 task_id。第一版只解除旧 task 引用，不默认删除催款单生成记录；如某次测试明确需要删除旧任务关联的催款单记录，应另行确认后按测试数据范围处理。

4. 执行前检查

先确认当前环境是开发或测试环境，并备份数据库或保留可重建脚本。

SELECT COUNT(*) AS legacy_task_count
FROM workflow_reservation_task;

SELECT hotel_id, task_status, COUNT(*) AS task_count
FROM workflow_reservation_task
GROUP BY hotel_id, task_status
ORDER BY hotel_id, task_status;

如只清理单酒店测试数据，先设置酒店 ID：

SET @hotel_id = 'HOTEL-TEST';

5. 清理 SQL

START TRANSACTION;

CREATE TEMPORARY TABLE tmp_dev_legacy_reservation_task_ids (
    id BIGINT PRIMARY KEY
);

INSERT INTO tmp_dev_legacy_reservation_task_ids (id)
SELECT id
FROM workflow_reservation_task
WHERE hotel_id = @hotel_id;

DELETE attempt
FROM workflow_reservation_opera_operation_attempt attempt
JOIN tmp_dev_legacy_reservation_task_ids legacy_task
  ON legacy_task.id = attempt.task_id
WHERE attempt.hotel_id = @hotel_id;

DELETE operation_row
FROM workflow_reservation_opera_operation operation_row
JOIN tmp_dev_legacy_reservation_task_ids legacy_task
  ON legacy_task.id = operation_row.task_id
WHERE operation_row.hotel_id = @hotel_id;

DELETE audit_row
FROM workflow_reservation_audit_log audit_row
JOIN tmp_dev_legacy_reservation_task_ids legacy_task
  ON legacy_task.id = audit_row.task_id
WHERE audit_row.hotel_id = @hotel_id;

UPDATE workflow_reservation_invoice_generation invoice_row
JOIN tmp_dev_legacy_reservation_task_ids legacy_task
  ON legacy_task.id = invoice_row.task_id
SET invoice_row.task_id = NULL,
    invoice_row.updated_at = UTC_TIMESTAMP(6)
WHERE invoice_row.hotel_id = @hotel_id;

DELETE card
FROM workflow_reservation_task_card card
JOIN tmp_dev_legacy_reservation_task_ids legacy_task
  ON legacy_task.id = card.task_id
WHERE card.hotel_id = @hotel_id;

UPDATE workflow_reservation_order order_row
JOIN tmp_dev_legacy_reservation_task_ids legacy_task
  ON legacy_task.id = order_row.created_from_task_id
SET order_row.created_from_task_id = NULL,
    order_row.updated_at = UTC_TIMESTAMP(6)
WHERE order_row.hotel_id = @hotel_id;

DELETE task
FROM workflow_reservation_task task
JOIN tmp_dev_legacy_reservation_task_ids legacy_task
  ON legacy_task.id = task.id
WHERE task.hotel_id = @hotel_id;

DROP TEMPORARY TABLE tmp_dev_legacy_reservation_task_ids;

COMMIT;

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。

6. 执行后验证

单酒店清理时使用以下验证 SQL：

SELECT COUNT(*) AS legacy_task_count
FROM workflow_reservation_task
WHERE hotel_id = @hotel_id;

SELECT COUNT(*) AS legacy_task_card_count
FROM workflow_reservation_task_card
WHERE hotel_id = @hotel_id;

SELECT COUNT(*) AS legacy_opera_operation_count
FROM workflow_reservation_opera_operation
WHERE hotel_id = @hotel_id;

SELECT COUNT(*) AS legacy_opera_attempt_count
FROM workflow_reservation_opera_operation_attempt
WHERE hotel_id = @hotel_id;

SELECT COUNT(*) AS legacy_invoice_task_link_count
FROM workflow_reservation_invoice_generation
WHERE hotel_id = @hotel_id
  AND task_id IS NOT NULL;

如果执行的是全量开发 / 测试酒店清理，验证时同步去掉 hotel_id = @hotel_id 条件，确认全库旧任务及直接依赖已清空或解绑：

SELECT COUNT(*) AS legacy_task_count
FROM workflow_reservation_task;

SELECT COUNT(*) AS legacy_task_card_count
FROM workflow_reservation_task_card;

SELECT COUNT(*) AS legacy_opera_operation_count
FROM workflow_reservation_opera_operation;

SELECT COUNT(*) AS legacy_opera_attempt_count
FROM workflow_reservation_opera_operation_attempt;

SELECT COUNT(*) AS legacy_invoice_task_link_count
FROM workflow_reservation_invoice_generation
WHERE task_id IS NOT NULL;

订单列表验证口径：

GET /api/reservation/orders 中新 V4 订单的 open_work_item_count 只看 V4 未完成订单任务。
清理后，新 V4 订单不应再返回旧 next_processable_task_id。
platform_source_message_inbox、V4 order task、V4 cards、V4 source notification、目录、用户权限和酒店配置应保持不变。
