Movement is Zero-Gravity's unit of value. A dashboard is not value. A decision is not value. Value only starts when a decision becomes action — and that action changes something an outside observer could measure.
Movement is deliberately more concrete than "impact" or "outcome". It has to be observable in the operational system, attributable to a specific decision, and recorded against a baseline. If none of those three conditions hold, the claim is closer to marketing than to evidence.
Every Zero-Gravity intervention is judged against movement it produced. The Evidence Pack is the artefact that shows it.
