Grand Convergence: Eleven Independent Substrates, One Drift-Diffusion Structure

Meta-analysis of the K-series (Papers 58–71): eleven independent scientific substrates where the same drift-diffusion Péclet structure was independently derived under domain-native vocabulary. Reports convergence statistics across the full corpus: 11 convergences, mean |ρ|=0.958 [0.934, 0.982], N=202, Fisher p < 10^-40, 0/26 kill conditions triggered. Establishes the universality claim for the Void Framework's mathematical apparatus.
