Qubes policies packges or scripts - how to reinstall/regenerate?

Hi!

It looks like I almost lost all of the default policies scripts in dom0 (in /etc and /srv).

Is there a way to reinstall them (which packages?) or a script to regenerate them?

Thanks a lot for your help!

(For the meantime, I’m using my own policies, but it’s not really efficient to discover missing policies when you need it…)
