// services/api/test/likes-realtime.e2e-spec.ts —— P2 Task 7 点赞与实时 e2e。
// 与 public-ov.e2e-spec 同模式：进程内起 cn + ov 两个真实入口，业务动作全走
// cn API（建相册/上传 complete/直驱发布事务），OutboxSender（生产实现）指向
// ov 入口真实 URL——点赞与 WS 广播作用在与生产链路同源的数据上。ov 入口按
// main-ov 同形装配 ContractWsAdapter（WS 与 HTTP 同端口 /v1/realtime）。
//
// 覆盖（任务验收 A09/A10/A21 部分）：
//   ① A09 点赞批次：连点 3 批累计 1+2+3（total/countVersion 单调）、同 batchId
//      重试幂等不加计（batchAccepted=true、like_batches 行数不增）、outbox_
//      stat_events 逐批落权威快照；delta 0/21、sessionId/batchId 65 字符 →
//      400；幽灵 token → 404 ALBUM_NOT_PUBLIC；幽灵照片 → 404 PHOTO_NOT_PUBLIC；
//   ② 基础限速：LIKE_SESSION_WINDOW_DELTA 压小（惰性 env）→ 窗口超额 429
//      RATE_LIMITED（代码语义验证；窗口本身 24h，不做时间旅行）；
//   ③ WS 协议：ping→pong 回显 ts；幽灵 token subscribe → error 帧
//      （ALBUM_NOT_PUBLIC）且连接保持（后续 ping 仍应答）；
//   ④ A10 房间隔离：两相册两客户端各自订阅（先以一次本册点赞证明双方订阅
//      均生效——非空转通过），跨册点赞只达本册房间，另一房间零消息；
//   ⑤ A21 合并广播：合并窗内两批同照片 → 恰一条 likes.burst（delta 求和、
//      originBatchIds 双元素、total 权威、burstId 存在），窗外无第二条；
//   ⑥ photo.hidden 实时：cn 隐藏 → 高优先级同步 → ov 应用后相册房间收到
//      photo.hidden（entityVersion 与副本行一致）；隐藏后点赞 → 404。
//
// —— 登记偏差（过期批次重放，不可 e2e）——
// 24h 窗口外重放已清理 batchId 的「再次加计」边界在 likes.service.ts 头注
// 分析（无永久幂等账本下的理论边界，由 sessionId/IP 滑窗上限钳制）；窗口
// 时间不可旅行，e2e 无法覆盖，随 Task 8 清理调度落地时以单元语义评审。
//
// —— 不在本 spec 的语义（对应实现位）——
//   · 传输层心跳踢除（HEARTBEAT_MS=20s 周期 ping/terminate）：真实 20s 等待
//     不值 e2e 时长，realtime.gateway.afterInit 直读契约常量（类型锁定见
//     contracts __tests__/realtime.test.ts）；P5 压测域验证。
//   · stats.updated：Task 8 浏览计数接线后由该任务测试。
