Given that the Ace Combat X's official website has stories on particular branches, we can consider them to be canon unless Project Aces states otherwise. For uniformity it would be good to have event pages for the missions that are not depicted in the website.

IMHO the canonical status can just be a small note/header for the related missions. Players should not feel their choices in the game to be invalidated by what was depicted in Ace Combat X's official website.
