I don't understand what anything you're saying has to do with what I said. My claim is that "groking the code" is not a binary, and you can balance between full vibe mode without ever reading it and requiring that you understand every single line, with the corollary that it's at least plausible that being on the far end of the spectrum where you never read it isn't safe to assume is the global optimum, and your rebuttal seems to be "well it's not the global minimum".
