Kotlin 侧（MethodChannel photolive/uploads + EventChannel photolive/uploads/events）：
- UploadPlugin：registerTask 入队 WorkManager OneTimeWorkRequest（unique
work=upload-task-{taskId}，expedited + OutOfQuotaPolicy 回退、CONNECTED
约束、指数退避 10s 起）、cancelTask / queryTask / ackEvents
- UploadWorker（CoroutineWorker）：dataSync 前台服务 + 进度通知，
OkHttp PUT（ETag 捕获、64KB 分片进度），结局分类：2xx→completed、
403→needsRenew、4xx→failed{HTTP_4XX}、网络/5xx→Result.retry（上限
5 次后 failed{NETWORK|SERVER_ERROR}）、缺文件→failed{SOURCE_MISSING}
- UploadEventBus：终态事件单调 seq + 未 ack 缓存重放（上限 200），
重注册/取消作废旧缓存——进程重启/切后台恢复不丢完成信号
- Manifest：FOREGROUND_SERVICE(_DATA_SYNC)/POST_NOTIFICATIONS 权限 +
SystemForegroundService tools:node=merge 补 dataSync 类型（已验证
合并产物）
Dart 侧：Transport 接口（init/complete/renew 留引擎，仅 PUT 委托）——
DartHttpTransport（Task 6 逻辑抽出，403→renew 异常归一）+ NativeTransport
（registerTask→事件流终态/进度映射、终态 ack、取消联动）；引擎传输选择：
Android 缺省原生，dart-define FORCE_DART_TRANSPORT=true 强制 Dart 路径；
失败分类与 dio 路径语义对齐（401 短退避/429 网络桶/SOURCE_MISSING 不
自动重试等）
测试：gradle testDebugUnitTest 29 例（executor MockWebServer 分类×10、
协议解析×11、事件总线×8）；flutter test 219 全绿（新增 NativeTransport
事件映射/取消/ack/并发路由、引擎×Transport 委托与 needsRenew 重注册、
传输选择矩阵）；flutter analyze 0；debug apk 构建通过
