FYI, you probably shouldn’t change the default priority of the proposed pocket in such a generic way, not anymore since the 24.04 release at least. It is already configured like backports (Pin-Priority: 100), which never install automatically but can be installed by temporarily changing the target release with -t switch of apt; any proposed packages that are already installed will be upgraded nonetheless, just like backports.
That should probably be a more targeted command to only get the linux-image-7.0.0-26-generic package installed. That way there can be no accidental upgrade to even newer proposed versions of linux-generic; eventually the latter (still tracking main) will just overtake the then aged out version from proposed.
