// services/api/test/watermark.e2e-spec.ts —— P4a Task 3 水印版本化 + 历史重生成
// 全链路 e2e。ONE spec 串完整业务流（cn API → worker 重生成（直驱，BullMQ 消费
// 由 worker/test/watermark.e2e-spec.ts 覆盖）→ cn/ov 公开侧服务 → ov 副本传播）。
// 进程内起两个真实入口（cn + ov，同 public-ov.e2e-spec 模式：OutboxSender 指向
// ov 真实 URL，ov 读到的数据与生产链路同源）。覆盖（任务验收）：
//   ① POST watermark-jobs（enabled）：202 {jobId, configVersion}；GET 状态形状
//      （current=最新配置缺省填齐 / jobs 创建时间倒序 / pending+total）；
//   ② 新照片发布即套用最新版（POST 后、任务 done 前发布 → watermark 变体对象
//      已产且与 browse 字节不同——契约 WatermarkJobCreated 语义）；
//   ③ 历史重生成（3 张）：直驱 processJob → done（progress=total=3, failed=0）
//      → cn 公开列表 browse 现签 URL 取回**水印字节**（≠ browse 变体对象）；
//   ④ A20：原图 objectKey 与字节全程零触碰；
//   ⑤ ov 传播：drainSender 后 albums_ov.watermarkEnabled/ConfigVersion 就位；
//      ov 公开列表 browse URL = 模式键 variants/{photoId}/{v}/watermark.jpg，
//      取回字节与 cn 水印对象一致；
//   ⑥ 失败注入：删 1 张原图 → 新版本任务 done 且 failed=1；失败张 cn 保留旧版
//      水印（行未覆盖）、ov 模式键 = 旧图拷贝（同字节——失败照片保留旧图）；
//      恢复原图后 re-POST → failed=0 全量收敛；
//   ⑦ 关闭版重生成：done 后 cn/ov 公开列表回落 browse 键；水印行删除、对象
//      保留（历史可溯）；
//   ⑧ 空相册：POST 即建即 done（无照片可重生成），有效位当场推进并同步 ov；
//   ⑨ 权限：协作者 POST/GET → 403；圈外人 → 404；admin → 202/200；
//   ⑩ 校验：enabled=true 缺 text.content → 400；opacity/scalePercent/fontSize
//      越界、position 非法 → 400。
