Not exactly. We figured out that Ralph is a changed, Universe MC ; and Vanellope a steadfast, Mind IC. However we were wrong about the Psychology OS and the Physics RS, it's the contrary.
The OS goal / concern is Learning, and the OS / MC problem Reduction. It kind of goes with what we were thinking, only we were looking at it the wrong way. The Narrative Argument is, as it stands : "Stop letting people pigeonhole you, and you can show them how to beat the game." So it still fits with the "you are more than your label" theme, but on the element level : being reduced to your role in the game creates problem both in the OS and for Ralph. Only when the characters will be able to Learn otherwise (Learn how to beat the game) will the inequity be solved ; otherwise it will remain something unconceivable for everyone.
At least that's my take on it with what has been published.
