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 source gives the year but no day - "Sally Schmitt opened The French Laundry in 1978 and designed her menus around local, seasonal ingredients" - so the pin sits on that year's last day, as a year-only date does.
The MICHELIN Guide's own entry, which states "a Three Stars: Exceptional cuisine restaurant in the 2026 MICHELIN Guide USA" and the $$$$ price band.
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.
