So it almost seems like the codes itself is giving everyone a chance to show that they can actually have a chance at surviving if they are quintessential in their rank right? Almost like it is searching for beings that are truly perfect at their level or beyond perfect! Mayhaps a sentient relic that's trying to find a candidate worthy of wielding it or a training/filtering tool for the ones/planes of existence that formed it to help evolve the strongest possible entities instead of the obvious trash relative to Noah in the story?
