Importance: CES as the unique stable fixed point of multi-scale aggregation is a foundational result. Beta function vanishing (rho exactly marginal) and scaling dimensions classify all perturbations.
Novelty: Completely new framework: multi-scale aggregation operator, scaling dimensions for ANOVA modes, no relevant perturbations existence proof, line of fixed points parametrized by rho.
Quality: Outstanding exposition: clear scaling dimension table, rho as marginal parameter, line of fixed points, universality class discussion. Well-structured (6075 chars).
