How it is measured
Early detection requires a retained source artefact: an API or catalogue listing, maker code, or a direct maker statement. The clock starts when Signal Forge records that evidence, never at an earlier publication date. Posts, rumours and forecasts remain in the timeline and do not count as detection; a later release does not validate an earlier forecast. Lead time counts complete days before release. Only models detected at least one full day early enter the median. Prices and context windows use the latest source values.
