צדיק גוזר והקב”ה מקיים
That’s a cop out and leads to a whole lot of other issues if taken literally. You’re essentially saying that anything a tzaddik says or does is automatically accepted in Shomayim and becomes reality. It’s very similar to what I’ve seen Chabadskers say in regards to Rav Schneerson ZT”L’s writings and speeches that they hold it’s impossible for him to have made a mistake on even a letter and therefore one can learn up his words as if they were, le’havdil, Torahs Moshe. Even a Gemara isn’t given to the same interpretation that Chabad lends to לקוטי אגרות. We understand that people are human, and errors arise, especially in the long process of recording, transcribing, editing, and publishing that takes place before a sefer is read.
