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.
Given as a target, not a fixed date, per the pin description: "…roduce ten times the power it consumes. Estimated date.…"
The Max Planck Institute (ipp.mpg.de) confirms ITER's revised schedule has "research activities on ITER will start in 2034," directly matching the pin's stored June 2034 estimated date, with full deuterium-tritium operation pushed to 2039.
Physics World independently corroborates the delay, reporting "full operation with deuterium and tritium... is now not expected until 2039," with activities beginning in 2034 as the pin's date reflects, alongside an "extra €5bn" cost.
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.
