Have you tried framing the hypothesis as a question in the dispatch prompt rather than a statement? Something like -- possible cause: X, please verify before proceeding -- instead of stating it as fact. Might break the assumption inheritance without changing the overall structure.

After a month of obliterating work with 4.5, I spent about 5 days absolutely shocked at how dumb 4.6 felt, like not just a bit worse but 50% at best. Idk if it's the specific problems I work on but GP captured it well - 4.5 listened and explored better, 4.6 seems to assume (the wrong thing) constantly, I would be correcting it 3-4 times in a row sometimes. Rage quit a few times in the first day of using it, thank god I found out how to dial it back.
