The word "VSNET" (solution for 11/10) appears in solutions.lua but not words.lua. We are convinced that this is the only possible solution to this puzzle and have included a screenshot of our guess attempts. We are not allowed to enter "VSNET" which we believe to be because it is not in the words list.

There are other words that are in the solution list that aren't in the words list. "ENDIF" and "DICKE" are the other ones we've found.
