- 业务 ORM 数据支持 MySQL 后端(asyncmy),新增 PortableJSON/
BeijingDateTime 可移植列类型、迁移脚本与切库脚本
- 修复 GET /api/scheduled-tasks/runs/{id} 的 _load_run 无限递归
(误调用自身,应委托 service.get_run)导致的 RecursionError 500
- 定时任务名按用户唯一:create/update/admin_update 主动校验,
冲突抛 DuplicateTaskNameError,路由转 409 而非裸 IntegrityError 500
- 补充回归测试 test_scheduled_task_run_lookup / _name_uniqueness
