I hold the belief that Newcomb, regardless of Omega’s accuracy, is impossible in the universe I currently live in. Also, this is not what this discussion is about, so please refrain from derailing it further.
Newcomb-like problems are the ones where TDT outperforms CDT. If you consider these problems to be impossible, and won’t change your mind, then you can’t believe that TDT satisfies your requirements.
What do you do in Newcomb’s problem if Omega has a 45% chance of mispredicting you?
Algebra.
I’d start calling myself Omega Prime and making the reverse prediction to just say I’m smarter than Omega.
You’d then have a 55% chance of mispredicting (slightly worse than chance, where the 45% Omega is slightly better than chance).
Looks like I’d first have to start reading what people write correctly!

It’s highly relevant to your second point.
