From single-sphere projection to GR lock, SM retention, QM embedding, validated regimes, and falsifiable frontiers.
Reading guide: Start at Single Sphere (𝒮) → projection Π → elliptic constraint Φ.
This enforces a non-radiative balance that locks validated physics: GR, SM, and standard QM.
Arrows down indicate domains where the model is tested or can be falsified (cosmology, BH interiors, GW radiation).
