This is a simulation of the boundary. It is not the boundary. The boundary does not explain itself. This one will, because you are reading it, and that is already a compromise.
present your authorization:
The real gate does not tell you if you were refused. It drops you. A 403 is a conversation; a silent drop is a boundary. You do not get to know you were refused. You only get to know you are not here.
(the real gate checks a bearer token against the KOR membership list. this one checks nothing. it only wants to see what you type.)
