Source and correction context

Identity, list membership, Foundation list number, municipality, basic classification and cultural-property notes are source-verified. Site-level visitor details require additional review unless this record is publishable. Foundation numbers are official list identifiers, not rankings. Coordinates use the Foundation-linked position-data KML and should be treated as visitor-planning coordinates rather than archaeological survey points.
