Probability Weights from Ring Contraction

Born's rule is not assumed. Probability weights emerge from the contraction of a sixteen-by-sixteen path-integral ring generated by the kernel's phase step. The amplification factor A-EGT equals 402.12, derived from ring geometry: 256 coherent pairings times the pi-over-two surviving lobe. Weights shift as rho evolves because the magnitude factor 1+2rho is position-dependent. The one open link is why the Bohmian shift specifically receives the amplification.
