Legend
A plateau. No one said it is all downhill from here.I can only suggest going back and, for example, reading threads started by @pemerton . Sure they didn't use the term apex but they denied that anything else increased agency, what else does that mean?
That handling the situation differently has nothing to do with agency because it is an outlier.
Possibly that agency is more about you deciding your action than you being able to narrate the outcome.
That is not a novel concept and @pemerton agreed not too far back that deciding where to go in a dungeon is agency (albeit in his view rather limited), even if you have nothing to go on.
