How we verify

The entries above show the sources and confidence scores recorded in our fact ledger.
Source tiers are internal classifications, not guarantees of accuracy or independence.
Several sources may repeat the same underlying account; a source count alone does not establish independent corroboration. We show the
street address only for non-residential public landmarks (museums, commercial and civic buildings,
publicly documented filming-location sites); the exact addresses of private residences and any
personal information are structurally barred from publication. Last reviewed June 2026.
