Yep, too overly specific or weird on some stuff, like for example on installing packages via terminal, I just went with suggesting it because I haven't fully red and understood your query, my bad :)
As for auditing tools, I can't think of any because there is a lot of ways how to check logs and it is messy ngl. If I'll be honest with you how I kinda survived linux is by automating backup of important files through nas and if I f*cked up my system, instead of fiddling the logs to find what went wrong, I'll just nuke it.
I hope they would include addon sideloading as well
