What I want to do is get the system back to just using the packages from stable rather than testing.
I have never tried the following, so it is better to test it in a virtual machine or inside a container. I would try to set priority of bookworm release high enough to allow downgrade. See apt_preferences(5) for details concerning pinning. However downgrade of libc makes "apt upgrade" really risky.
Do not forget to remove configuration with excessive priority afterwards.
