3 piece(s) of evidence not counted — why
  • A1: GitHub organization has not verified this domain (is_verified != true)
  • A3: fewer than 1095 days until expiry; not the long prepaid term typical of corporate registrations
  • A4: DV certificate carries no organization name (most modern tech companies use DV; this is expected)
