Field notes
The homepage uses a watchlist structure rather than a conventional article feed, with active and completed states plus filters for three technical fields. Individual records attach a latest source and classify the development as a milestone, discussion, rumor, or paper. The featured Hodge Conjecture record is unusually explicit about separating a social-media user's assumption from what reporting confirms, giving the site a visible editorial rule for handling breakthrough claims.
