How we fact-check

Each claim is logged with a status: confirmed, disputed, unverified, or myth. Unverified claims never appear as facts.

Source ranking

1. Primary sources: letters, diaries, documents, exhibition catalogs.
2. Museum and archive records, catalogues raisonnés.
3. Academic books and peer-reviewed articles.
4. Quality encyclopedias and art publications.
5. Blogs and Wikipedia: used only to find better sources, never as proof.

A key or disputed fact needs at least one source from the first three levels. When sources disagree, we show both and explain which we trust more.
