I doubt that you would install this application without even reading the README, so I don't understand how citing literally the second paragraph of the README helps.
> it's critical to know whether it's vibe coded
Strictly speaking, the only way to be sure that something is not vibe-coded is to either have a proof that the code were published before vibe-coding tools were available or to hand code it yourself.
Also, if you think that knowing if something is vibe-coded is so important, it is unwise to attack people who honestly tell you that something is vibe-coded.
