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.
The Denver Gazette[3] of Monday 11 May 2026 says Theo Adley "opened his second restaurant Heretík ... at 1441 26th St. on Friday", which is 8 May. Westword[4] had announced on 1 May that it would open on Wednesday (6 May); the report written after the event is taken over the announcement.
The restaurant's own website, linked from its New York Times entry. It confirms the restaurant is operating but does not date the opening.[1]
Written the Monday after the opening; says Heretík opened "on Friday" (8 May) at 1441 26th St. and describes it as counter service.[1]
The pre-opening announcement, which gave Wednesday (6 May) as the day. The Denver Gazette[3] reports it opened on the Friday instead, so this is kept as the announced schedule, not the date.
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.
