After open source models are restricted, the first step is model approval.

开源模型一旦开始受限，最先冒出来的不是“还能不能下载”，而是“谁还能用”。这一步看起来像流程，落到工程里其实是控制面：同一套模型文件、同一批提示词、同一组回归脚本，原来默认能跑，后来要先确认审批、镜像、权限和回退路径，才算真正进入工作流。

这种变化很容易被低估，因为它不会立刻让系统停机。 The model is still there, the interface is still there, a certain account may still be able to pull an image, and the first round of verification may still be passed.真正开始乱的是第二层：一部分人拿到的是旧版本，一部分人拿到的是量化版，还有一部分人根本过不了权限。 When troubleshooting, everyone was still talking about the same model name, but they were holding different objects.

At this time, it is very dangerous to continue to treat model access as “temporarily giving a token”. Temporary authorization is best at creating illusions: being able to run today does not mean that you will recognize the same path tomorrow, and today’s return results do not mean that it can be repeated tomorrow. After the model is restricted, the first thing that becomes expensive is not the token, nor the computing power itself, but the judgment cost. Every time you locate a problem, you must first ask which version you got, which image it came from, whether the approval chain has changed, and whether the rollback point has been retained.

So what really needs to be done first is not a more beautiful download page, but model approval.审批不是文书活，它决定谁能进入生产基线，谁只能留在试验区，谁的结果可以被拿去做回归，谁的输出只能算一次性参考。 After closing this layer of boundaries, the model begins to look like a maintainable dependency; without this layer of boundaries, the so-called “usable” is just a lucky hit.

最实用的做法也不复杂：把模型版本固定成明确基线，把镜像和来源写进记录，把审批结果和回退路径放进同一套留痕里。 In this way, the limitation comes, and the loss is the entrance width, not the workflow itself. What really needs to be protected is never that “everyone can touch it”, but that after touching it, you can return to the same line.
