I like this idea -- The paradox goes away if, say, Dumbledore
polyjuiced himself (or is powerful enough not to *need* PP) as Harry.
My only problem is, why would he bother polyjuicing himself?  He had
no way of knowing at that point that Harry would go back in time --
Unless he saw that Buckbeak escaped and surmised that Harry needs to
go back in time to save him.  But then, how did he know if was
Future!Harry and not Present!Harry who saved Buckbeak?  Of course it
occurs to me that Dumbledore himself might have time-travelled back,
and that it's Future!Dumbledore who accompanies Fudge and MacNair to
Hagrid's hut (Hence his ironic "How Extraordinary"!)

I think I need a pencil and paper to figure this out...

Yes, it's hard for a *lot* of us, because if the future is
predetermined, then these's no Free Will, and all the lip service
Jo and Dumbledore give to "the choices we make" is invalidated.
