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: "…opened to worshippers in December 2024. Estimated date.…"
Wikipedia's[1] "Reopening of Notre-Dame de Paris" article confirms the cathedral "reopened on 7 December 2024 following completion of the restoration work," but the retrieved content does not address the pin's separate claim about exterior/flying-buttress work continuing toward a 2030 completion, so it only weakly supports this estimated pin.
Architectural Record reports that while Notre-Dame reopened to the public in December 2024, full restoration of the exterior (scaffolding, flying buttresses, sacristy) will not be complete until 2028 at the earliest, consistent with the pin's later 'restoration complete' event being distinct from the 2024 reopening.
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.
