RESEARCH RELEASE 0.2 / 20 OCTOBER 2026
Optical benchmark first. Alpha 1 hardware on hold. No physical coupling, apparatus performance or propulsion result is established. The next milestone is a qualified measurement of known photon momentum.
The decision
Continue optical benchmark design. Characterize a graphene stack before putting it on the balance. Hold A1-Y hardware until a microscopic coupling and a defensible comparison with existing limits are reviewed.
The evidence
The published graphene efficiencies describe optical scattering. A derived full state difference must include all orders. Existing gravity constraints need a model-specific mapping. Instrument uncertainty requires measured stability and controls; a simulated error budget cannot qualify hardware.
