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.
Happened as dated, per the source: "the basin was inaugurated on May 2, 2024."
Olympics.com's own retrospective piece, "The Seine reopens: how the Olympic Games helped Paris reclaim its river," carries a stored publish date of 1 September 2024 - after the Games and after the pin's stored 2 May 2024 inauguration date - reporting the outcome rather than the opening itself; the domain could not be verified for direct fetch.
France 24's own headline, "Paris inaugurates massive water storage basin to clean up Seine," carries a stored publish date of 2 May 2024, exactly matching the pin's stored inauguration date, though the domain could not be verified for direct fetch.
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.
