The article calls the origin details sketchy and presents a drilling accident and deliberate ignition as the received story. Its image caption and introductory timing are not fully consistent, so this dossier does not promote one repeated starting year to a verified archival date. A Turkmen gas-sector review reports reduced combustion in June 2025 and refers to satellite comparison. That later report concerns changing fuel supply, not proof of how the original opening formed.",
