Much appreciated! I got back up under there with the camera again and went through all four possible avenues - the fill port, drain port, the tiny secondary port on the bottom driver side of the tc housing, and the low-range port - but was never able to spot anything that would let me definitively identify if full-time or part-time, at least inasmuch as I can tell.

So this is not a definitive answer to your question…but the part time kits come with a new decal that is supposed to go over the original Emergency Drive decal in the glove box to describe the new operation. People probably don’t always apply this…but if it’s there…I’d say it’s pretty certain it’s been changed.
See attached image.
No dice; mine still has the original full-time decal. In fact, I looked everywhere for any sort of indication that something had been modified, including around the tc housing. Absolutely nothing.
So with all that said, I bought four quarts of new, clean TCL-1. So once it comes in this week, at the very least I'll use it to do the torque bias test, see if this thing is full-time or part-time, then I can change the fluid out if I find it is in fact part-time. If for some reason it's still full-time though, I wouldn't be surprised if the clutch cones were burned up by this point, as it's been driven between the PO and myself at least 10k miles with the front hubs unlocked (in e-drive per the dash light - no remaining vacuum hoses going to the tc intact in the engine bay).
Here's some potentially pertinent info in the meantime: Back when I first bought this in 2022, and mentioned early in this thread here
, there were either a new or old Quadratrac belt and control diaphragm lying in the bed of the truck deteriorating from the elements for who knows how many years. Clearly someone was going to do some work on the tc at one point, or had done some work but stopped, I'm not sure. But there were no parts indicative of a part-time kit. Whoever bought those parts came before the PO, as PO really didn't know anything meaningful about the truck or its history, and seemed to be flipping it after finding out how much work needed to be done on it. Perhaps they were going to replace the belt because the current one is slack, and the diaphragm is broken?
Either way, I did confirm that the belt has at some point been slapping around the inside of the tc; see photos below. I just don't know if the belt that's in there is the old one or the new one in that set of parts I found.
EDIT: I recalled also being told at one point there was a split somewhere in the tc housing, but I couldn't find anything for the life of me. Uploaded a video
to the shared Dropbox folder just going over it all.
