Well, my conclusion is that you are conclusion is not correct.
Use that big searchbox you recommend and you will see that most of the breakages about pamac is as I have described and they are not about breakage of the system because someone has used pamac to install an application.
Well stay in your belief that you are right. I have said what I have said and I stand by it.
Pamac is a GUI frontend for libpamac. Libpamac is a “wrapper” around pacman/libalpm with some extended functionality to optionally manage AUR, flatpaks and snaps.
If anything of this is unclear to you, use your favorite search engine to find out more about the subject,
If you are trying to belittle what I have said by this, this is quite a futile attempt.
