feat(api): batch hide with per-item results and owner transfer
P4a Task 2(A16/A17):
- POST /albums/{albumId}/photos/hide-batch:逐项结果(部分成功)——
不存在/他册 → ok:false PHOTO_NOT_FOUND;非 published(unpublished/
deleted)→ ok:false PHOTO_NOT_PUBLIC;已 hidden → ok:true 幂等 no-op
(同值不产生第二次事件/审计/版本,P1 语义);published → 逐照片事务
(条件更新 + outbox photo.hidden 高优先级 + audit photo.hide)。
results 与请求同序;权限同管理照片列表(仅创建者或管理员,404 防枚举);
单批 1..200(DTO 层 400)。
- POST /admin/albums/{albumId}/transfer:admin-only owner 移交——事务内
条件更新 ownerId+entityVersion+1(乐观重试)+ 成员互换(目标 upsert 为
owner,原 owner 按 keepAsCollaborator 降级 collaborator 或删行)+
outbox album.updated(标准载荷,版本推进)+ audit album.transfer
{from,to,kept}。目标校验同成员邀请资格谓词(active/未锁定/未停用);
自交接 400;photos.uploaderId 不动(A17 历史上传人不变)。
- e2e(batch-ops.e2e-spec,双入口 harness):8 用例覆盖逐项结果/幂等/
入参权限矩阵/ov 传播(真实发布链→隐藏→photos_ov=hidden+公开列表剔除)/
keep 两分支/目标校验/交接后权限(新 owner 管理、旧 owner 保留协作者
可上传)。
