If you have a steadfast character and the story ends up as failure, you know they were not standing on the right spot. Its pretty easy to do for the change character. For change, if it is success and they changed, they must’ve started on problem, and jumped to solution in the end. So the MC will be on the Objective Problem element in build characters and the Obstacle will be on Solution.
In that case, the Obstacle was a friend trying to help the misguided MC see the light and change course, so the Obstacle was on the solution element all along. The main was on the problem and changed in the end. But if the change results in Failure, then the MC was on Solution all along, the Obstacle was on Problem, was a true foe, and the MC jumped FROM solution to Problem, causing the story to end in failure. Steadfast stories are bit more complex, because the terms “focus” and “direction” don’t carry any intrinsic positive or negative feel to them like problem and solution do.
In fact, it is the judgment of Good or Bad that determines which of the two elements the MC and OC are on in a steadfast story. Focus is seen as the symptom, direction is seen as the treatment. If you have a steadfast Main character who ends up still having their angst (bad) did they stick it out on the treatment or on the symptom? In fact, they are stuck with the symptom. So, they would reside on the focus element. But if the character remains steadfast, and they are over their personal angst. then they are stuck on the treatment, which means they still have the resources.
