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.
SanDiegoVille's report of 14 December 2025 describes the restaurant as already open - "San Diego's Convoy District has welcomed a new heavyweight ... with the opening of Mikiya Wagyu Shabu House" - but names no opening day, so the pin is anchored to the report's own date.
Chubby Group's own locations directory, which confirms Mikiya Wagyu Shabu House as one of its brands and lists the San Diego site.
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.
