3 piece(s) of evidence not counted — why
  • A3: registrar (Squarespace Domains II LLC) is not a brand-protection registrar
  • A4: DV certificate carries no organization name (most modern tech companies use DV; this is expected)
  • B1: entity not anchored: no canonical Wikidata item, so an arbitrary item's P856 cannot corroborate
