Importance
The generalized R_0 crossing is the master activation threshold governing all four hierarchy levels. Core spine result -- nontrivial equilibrium iff cycle product > 1.
Novelty
Completely new framework adapting epidemiological R_0 to economic adoption thresholds via next-generation matrix. Cross-level amplification enabling sub-threshold activation is novel.
Quality
Excellent: clear NGM formulation, activation threshold theorem, cross-level amplification, calibration table, and five testable predictions. Longest article (7214 chars).
