- 店铺字典（迁移 0057）：大按钮点选 + 「新店」自定义自动登记；重命名可级联、 停用/备注；列表行内改、详情、筛选条共用同一个 picker - 新建强校验：订单编号/店铺/CK/礼包名/主页截图必填；贴 CK 即探针预览， 读不到绑定角色禁止提交；礼包用工作台配置的活动 SID 现拉（浏览器缓存 + 强制刷新） - 图片：绑定图停用、「绑定斗鱼号」下线（绑定关系改由探针读 bind_game_*）， 主页截图改为新建必填（弹窗内先传 OSS 再随表单落库） - 同买家多单软识别：按「绑定账号 + 绑定角色」整批一次查询，列表「同买家」列 + 详情分组，点单号直接切单 - uid 放开唯一性（迁移 0058）：同一份 CK 可服务多单，原 409 冲突改为提示 + 审计 - 列表体验：序号列、搜索扩到 11 个字段、CK 状态列截断、新建弹窗放大并去滚动条 - 验证：pytest 932 passed / 6 skipped；接口冒烟 56 项全绿；tsc+eslint+build 通过

"""Alembic 迁移链冒烟测试（在真实 MySQL 临时库上执行）。
|
||
|
||
覆盖三件事：
|
||
1. 链完整性：只有一个头版本、头与最新迁移一致、每个修订的
|
||
down_revision 都能回溯到根（无悬挂引用、无分叉链）。
|
||
2. 全部迁移脚本可编译：防止迁移文件被改坏后部署流程才暴露。
|
||
3. 空库整链执行：迁移脚本在真实 MySQL 临时库上执行 `upgrade head`，
|
||
随后校验表/列/索引与 Base.metadata 模型元数据对齐（模型要求的不允许缺失），
|
||
并确认迁移新增的复合查询索引确实落库。
