Activation Threshold R0
Spectral radius of the next-generation matrix determines whether the hierarchy sustains activity.

Score Reasoning
- Importance
- Core spine result: R0 threshold determines whether the hierarchy activates at all. Central to Papers 4 and 6, governs cross-level amplification.
- Novelty
- Novel application of next-generation matrix from epidemiology to CES hierarchies. The cross-level amplification result (sub-threshold individually, super-threshold collectively) is a new theorem.
- Quality
- Well-structured article with LaTeX formulas, clear exposition of threshold condition, cross-level amplification, and connections to upstream reform. Good cross-links.
