I'm trying to rewrite the following sentence into another form:
Client requires that the software run with high performance and be bug-free.
My rewrite looks like this:
Client has strong demand for high performance and ______ from the software.
I'm looking for the noun form of "be free from bugs" for the blank. I hope that the solution is general, because in the future I will try to rewrite "loyalty-free", "alcohol-free" etc. in a similar fashion.
