This document registers three specific, quantitative, falsifiable predictions derived from the conserved-whole force-partition framework (Lynch, 2026) in advance of data release by the Nancy Grace Roman Space Telescope. The framework proposes that gravity and electromagnetism are two complementary expressions of a single conserved force-budget, partitioned differently at every scale. Three predictions are registered: (1) dark energy equation of state w = −1.000 exactly with no time evolution; (2
