Send something worth waiting for
Fold your note into a paper airplane and send it soaring across a real map. It arrives on real-world time — shaped by distance, your plane, and the wind.
Pace needs two or more snapshots. This launch has 1, so velocity and momentum read as unmeasured rather than zero.
A source that found nothing is a measurement. A source that has not run is a gap. Neither means the launch lacks the thing.
