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 saved date is an estimated tracking or capacity-trajectory marker, not a verified exact opening day. Construction status follows the cited dated physical scope; no completion is inferred from elapsed targets.
Construction research 2026-10-24: Epoch’s[1] 2026-03-12 observation documents remaining physical construction/installation for this named buildout. In Progress does not complete earlier operating buildings or future capacity. Power and accelerator counts remain Epoch estimates, not an operator-certified rating. Modeled 2025-dollar capital costs include compute hardware and are not a source-native construction budget.

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. A picture that shows something else, or shows it badly, is looked at too, and moved down or replaced.
