+
+为配合 `OperationSystem.MaxTimeSlice` 的时间切片预算，`AsyncOperationBase` 提供了内部属性 `IsBusy`（`internal`）用于任务在 `InternalUpdate()` 内主动让出本帧预算。
+
+- 推荐用法：在 `InternalUpdate()` 内部（或内部子步骤）在执行重逻辑前判断 `IsBusy`，若繁忙则 `return`，把工作拆到下一帧继续执行。
+- 同步等待特殊处理：当调用了 `WaitForAsyncComplete()` 进入同步等待阶段时，`IsBusy` 会强制返回 `false`，避免因时间切片判断导致同步等待无法推进。
+- 注意：`WaitForAsyncComplete()` 会阻塞主线程，应谨慎使用；同步等待阶段不受时间切片保护，可能带来卡顿。

+- 多包裹场景下，可根据游戏状态动态调整包裹优先级
+- 例如：进入战斗时提高战斗资源包的优先级，退出战斗时恢复默认优先级

-- 仅当存在非零优先级时触发排序
-- 使用 `List.Sort()` 进行原地排序
+- 新操作添加时：若新增队列存在非零优先级，则触发排序
+- 运行中修改 `Priority`：调度器会在每帧 `Update()` 的排序阶段检测 `IsDirty` 并触发重排；若在某个操作的 `InternalUpdate()` 内修改（本帧排序已完成），则新的优先级会延后一帧生效（可能与预期不符）
+- 若期望本帧生效：请尽量在任务入队前或本帧调度器 `Update()` 开始前设置 `Priority`，避免在 `InternalUpdate()` 内临时调整
