 **排序规则：**
 - 新操作添加时：若新增队列存在非零优先级，则触发排序
-- 运行时修改 `Priority`：会在下一次调度器更新时自动触发重排（即时生效，通常为下一帧）
+- 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
 - 排序使用 `List.Sort()` 进行原地排序；频繁修改优先级会带来额外排序开销，建议按需使用
