How we did this
This sample page was built for launch preparation. The published story carries its method note here: the records requested, the people interviewed, and what we could not confirm. Lampline asks the people a story criticizes for comment and says what they said, or that they did not respond. Any use of AI tools in reporting or production is disclosed here.
