Those seem to have been a very long "few hours"...

This looks interesting! I'll be following it.

It seems like a very ambitious project. In particular, approaching a piece of serial fiction as a classically structured work is possibly doable, but seems scary. The shape of the story can vary in the author's mind from chapter to chapter, so you'll be picking up contradictory clues, and end up seeing the story as a whole as a superposition of different patterns (or multiple time-displaced instances of a single one; I agree that Harry seems to be starting a second hero's journey before finishing his first.)
