No birth date, nationality, employer, office, publication, award, investment, software contribution, or organizational role is asserted here without a resolved record. The cited searches are authoritative discovery sources, not evidence that every returned item belongs to John Graham-Cumming. Future expansion should cite the specific institutional record that supports each added fact and preserve uncertainty where identifiers conflict.
