The first entry is always the pin's source. Overall confidence is a weighted average of how firmly each reference supports the start and end times used above; a reference counts half as much for every 180 days older than the newest.
Given as a target, not a fixed date, per the pin description: "…would be the tallest dam in the world. Estimated date.…"
Al Jazeera's own reporting describes the Rogun Dam as still under active construction and quotes Tajik officials calling it a matter of 'life or death,' but states no specific completion date, consistent with the pin's own 'estimated date' framing for September 2029.
Webuild's own press release documents ongoing construction progress on the Rogun Dam - reaching roughly 1,110 metres in elevation en route to its planned 335-metre height - but gives no specific completion date, leaving the pin's estimated September 2029 target unconfirmed by this source.[1]
Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most.
