我在这套机制里做的事情只有三件：决定什么时候切换（执行卡死了就切到 NotebookLM）、判断任务报告的结论是否可信（模型没有眼睛，视觉判断必须由我来做）以及维护问题树（决定下一个最重要的子问题是什么）。其他所有事情，都在这个机器对机器的闭环里自动完成。
This fragmentation hurts portability. Code that performs well on one runtime may behave differently (or poorly) on another, even though it's using "standard" APIs. The complexity burden on runtime implementers is substantial, and the subtle behavioral differences create friction for developers trying to write cross-runtime code, particularly those maintaining frameworks that must be able to run efficiently across many runtime environments.
