// services/api/test/public.e2e-spec.ts —— Task 22/23 公开读端点 e2e（先写后实现）。
|
||||
// 真实 app + MySQL（Prisma 直种）+ 真实 MinIO（storage.put 真 JPEG：banner 与
|
||||
// thumb/browse 变体对象）。公开端点匿名访问（契约 security: []）：全程不带
|
||||
// Authorization 头——若误挂 SessionGuard 会以 401 暴露，测试即失败。
|
||||
// Task 22 覆盖（getPublicAlbum）：
|
||||
// · locale 解析：en/zh-CN 精确命中；缺省 → defaultLocale；翻译缺失 → 回退
|
||||
// defaultLocale（需求 4.7）；非法 locale（'fr'）→ 静默回退（Task 5 决策，
|
||||
// 不报 400）；
|
||||
// · 可见性：offline / publicEnabled=false / 幽灵 token → 404 ALBUM_NOT_PUBLIC；
|
||||
// · categories：按请求 locale 解析名称、sortOrder 升序；分类缺 resolved 语言
|
||||
// 条目时按 defaultLocale 回退；
|
||||
// · banner：album_assets(kind=banner) + 真实对象 → 签名 URL 可取回真实字节、
|
||||
// expiresAt 晚于现在；无资产行 → null；
|
||||
// · viewCount P1a 占位 null；startAt/endAt ISO + timezone 原样返回。
