Did you miss the part where information is acquired and processed before will is formed and determined by neuronal interactions within the system, which do not involve will?
Did you miss the part where the system which acquires and processes the information is itself operating on a series of instructions, will unto a requirement?
You want to find something that isn't a "will" driving these things, but you won't, because like in set theory,
it's wills all the way down.
Don't act obtuse: The order of events from input to experience has been thoroughly explained and
the steps in the middle there, all of them from input to experience, are "wills" in this framework.
Most wills' requirements as such are "null" so their freedom value is "trivially free".
The physical "will" of the rock, for example, lacks any requirement to do as it does, pushing a kinetic wave from one end to the other. It is a "trivial will". Most people would probably call that "unwilled" but I don't get to make that distinction except when I clarify that "unwilled really means 'trivially willed'", and using that language would just complicate the discussion with points at which folks like yourself could kick mud into the water around it. So I call them "trivially willed" rather than "unwilled".
The physical "will" of the dwarf, however, has a requirement. That requirement will either be met or it won't. This will is not "trivially free" but is in fact "observably not free" because the "door" of "open that door" is "locked". If the door was not locked, the will would be "free". As the door must have always been locked, this particular will must have always been destined to be unfree.
But in the deterministic universe the same as this other one except for the difference of "the door doesn't get locked, and so also the difference of all events unfolding thereafter", the will is free and
this particular will must have always been destined to be free, within this second deterministic universe.
Now that you are at the point where you are acknowledging at least the presence of a "will" in some respect, though, we can get on maybe to discussing the calculus of "freedom" and the utility of calculating it on provisional terms?
I think we both agree in fact that "the agent" does not decide the freedom of their wills. The provisional freedom is based on contingents which are not necessarily real and cannot be assured to be so. At best they can
assume. It will be the case that either it was free or it wasn't, though. Everyone here in fact agrees (I think) that an individual cannot
decide to be free with respect to some given will: they either always will have been free or always won't have been. But understanding whether and why is valuable insofar as it tells us whether "don't bother".
It is also useful in determining "this will ought not be free, as this will being free makes all these other wills including all of mine, including the will 'to live', 'not free'; let us gin up a will that is very likely to be free which is 'stop that guy before he can murder anyone else'". It allows us to calculate contingents which make for more effective, more free, wills.
You, for example are "not free" with respect to wishing freedom to not exist. I'm pretty sure that as long as contingents exist in the universe ("Event A is contingent upon Event B"), freedom is going to be there, real and calculable and observable.
Until you recognize that "the agent may hold a will" "the will may or may not be 'free'
as determined by causal necessity", we will continue having this discussion.
Once you are ready to accept "the definition of 'free' is a description which applies to a 'will' exactly when that 'will' contains a requirement that SHALL be met" we can get to discussing more interesting things about the game theory around "will" and "freedom", like opposed action or justice or discussing why some wills "cannot be accepted in any way to be allowed to remain 'apparently free'" or why this particular (and admittedly counter-intuitive) definition of "free" is correct, and completely sufficient for its role in discussing ethics in "hard math" terms.
