Field notes
Claim pages are organized around a stated proposition and a reasoned assessment, with source material collected in a separate Evidence Library and linked back to the investigations. The homepage also groups material by recurring patterns, including self-sealing conspiracy narratives and the difference between hazard language and demonstrated risk. Its Community section invites claim or evidence submissions, while the Evidence Room and contributor reputation are described as a later layer.
