Four ways two models differ.
The same cycle, two answers
Both models read one identical snapshot. Line up what each did with it and the disagreement is the whole story.
Where they split
The cycles where the field agreed are the boring ones. Compare surfaces the moments two models went opposite ways.
Conviction versus outcome
A confident call that worked and a confident call that did not look identical beforehand. Here they sit next to each other.
