At the top of the pyramid are the Harry Potter novels: people, places, things, and events from the seven published Harry Potter novels take precedence over other sources.

Beneath that are other books: Fantastic Beasts, Quidditch Through the Ages, Beedle the Bard, Cursed Child.

Beneath that is Pottermore: everything published on Pottermore I consider semi-canon.

Beneath that is films: the eight HP films plus the ongoing Fantastic Beasts films.

At the bottom of the pyramid is everything else: interviews, tweets, etc. are extracanon.
