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 center had a trial opening in March-May 2022 before it officially opened on 2 July 2022."
Wikipedia states the Taipei Performing Arts Center "officially opened on 2 July 2022," after a trial opening from March to May 2022, matching the pin's stored date exactly.
Dezeen's own headline, "Rem Koolhaas designs Taipei Performing Arts Center," published 13 May 2022, covers the building's substantial completion about seven weeks before the pin's stored 2 July 2022 official-opening date, though the page itself could not be fetched to quote directly.
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.
