CI / flutter-gates (push) Successful in 2m15s
- 30 秒定时冲刷：AnalyticsService.startPeriodicFlush/stopPeriodicFlush， 前台期间 Timer.periodic 周期冲刷；SessionTracker 新增 onEnterForeground 回调，退后台停（并保留既有 flushNow 触发）、回前台恢复，App dispose 收尾。 - 失败退避：网络错误/5xx 后 30s→60s→120s 指数退避封顶 5 分钟，退避窗口 只挡定时冲刷（flushNow/满 20/冷启动显式触发不受限），上传成功即重置； 429 改按网络错误同路径保段重试（Retry-After 分支待后端限流落地）。 - anonymousId 持久化：restore 时从 shared_preferences 采用/落盘 pb.analytics.anonymousId，首次生成后跨冷启动稳定；读取失败降级 进程内临时 id 不崩溃。 - 测试 272 → 286（+14）：fakeAsync 定时/退避 8 个、anonymousId 4 个、 429 保段 1 个、前后台回调成对 1 个；analyze 0 问题、format 无 diff。 Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
