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: workers "discovered structural steel columns buckling" on the morning of July 7, 2026.
The Real Deal's own headline, "Engineers blame lack of steel reinforcement on Pfizer HQ structural failure," published 17 July 2026, ten days after the pin's stored 7 July 2026 date, is consistent with a follow-up engineering investigation into the earlier incident, though the article text itself could not be retrieved (403 error).
CNN's own headline and URL, "July 7, 2026 - Manhattan high-rise at risk of partial collapse," date this live-news coverage to the pin's exact stored 7 July 2026 date, though the article body itself was blocked (451 error, unavailable for legal reasons) and could not be quoted 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.
