I... get the impression you read my first paragraph, and ignored the rest. Yes, I acknowledged later on that this is not how it works, and in the final paragraph acknolwedged this is not how it works even in the Alexander raid.
And while you said you'd said your last on the matter, there was one thing you mentioned that I had to address:

If this were to be observed outside of time, then the WoL would appear to enter the loop at its earliest apparent point, and exit the loop at its latest apparent point. But Mide is different: She exists entirely within the causal loop. If one were to observe the past and the future from Mide's perspective, they would come to the conclusion that they are one and the same: A chain of events with no beginning nor end. This is the Bootstrap Paradox.
No, Mide's treatment is NO DIFFERENT than the WoL's with the exception that, in the end, she is transported to the past and lives out her life there. Her life follows a single timeline. She' is born, she grows up, she has time travel shenanigans with Alexander, she travels to the past, grows old, and dies. The WoL is born, grows up, has time travel shenanigans with Alexander, then in the future presumably grows old and dies, though that future is not yet written.
Mide does not go through the loop over and over. She goes through it once. An observer outside of time watching her would not see her go around the loop over and over. If they were to follow her life, they'd see her loop one time, and that's all. Just like someone watching a roller coaster will see the car go through the loop one time.
This is true for all of the actors in this scenario. Discworld has an example of the "endless loop" that you postulate in the book "Pyramids":
In that book Dios, the high priest of the Egypt-analogue kingdom, has been high priest for as long as he or anyone else can remember. At the end of the book he's sent back in time, where he helps to found the kingdom and immediately becomes its high priest. He was never born, never dies, and has always been and always will be an old man acting as high priest over and over for the first eight hundred years of his kingdom's history. From his personal perspective it would be an endless eternity - or would, if, as a mercy, his limited memory prevented him from realizing his fate.
THIS would be a case where an observer outside of time could truly say the cart is going around the loop endlessly. Mide's case is different. Only a segment of her life is spent in the loop, goes through it once, and that's it. A segment of her life exists before the loop, and after - it just happens that the segment that occurs after takes place chronologically in the past. To her, though, and to an outside observer watching her life from start to finish, though, it's a single, unbroken path.
BOTH of these examples are Bootstrap Paradoxes, in that actors in the loop take actions that lead to them going to the past and setting things up so that they will take those actions, but you can hopefully see how they're different: in one the actor has no existence outside of the loop and rides around it over and over, in the other the actor has an existence before entering the loop, and an existence after leaving it.
