Analytic declared rule at C=1: favored joint relation cos^2(delta); complementary relation sin^2(delta); E = cos(2 delta); canonical CHSH angles give S = 2*sqrt(2) = 2.828427124746. Local marginals remain 50/50.

Frostyverse physical proposal: daughter structures remain physically related through a coherent FrostGrid disturbance relayed across the connected FrostLine/FrostCell network between them. This relationship is not assumed to survive indefinitely; the provisional coherence parameter C represents progressive loss/muddling of that shared relation, but no distance-to-C law is derived yet.

Monte Carlo approaches the supplied analytic value as samples increase and may fluctuate above or below it. Browser output includes an approximate 1-sigma sampling uncertainty for CHSH.

CLAIM BOUNDARY: this is a rule-consequence audit, not an independent lower-level derivation of the shared relation or product compatibility rule from raw FrostGrid geometry.
