Get a listing of all BI Publisher seeded account (roles) and a list of all permissions meanings?

I would like to get a listing of seeded BI Publisher accounts (roles) and a listing of all permissions associated with the roles. I would also like to understand what each permission does.

The reason for the ask is someone with both BI Author and BI consumer role had the ability to delete a folder within out structure which caused adverse issues for the other team members.
