Sounds like it's hillclimbing all the way down!
Cool framing. I'm excited for the parallel construction of ___ as pathfinding through weight space.

1) Pretraining creates a bias _towards_ "correct answers" with each inference step
2) A longer walk is more likely to land in the correct region, given it's easier to verify you have the correct answer than to create it
3) RL selects the subset of walks that lands in the correct region and tilts the distribution in favor of such walks
4) By 2, that trains towards longer walks
...Is that correct?

Reasoning (i.e. bubbling those remembered words up into your mental context, and then using a special "reacting to words" bridging reflex on them) is how you leverage memories-of-words into useful behavior.
An especially useful version of this is planning, where you chain through "mere words" until you end up at words that declare to yourself what you're about to do; and then you rely on your bridging reflex to react in a way that's constrained by the plan you generated.
