Structural Vulnerability in Hierarchical Networks: A Dependency-, Redundancy-, and Level-Aware Framework and Its Empirical Limits

Classical node-importance measures (degree, betweenness, closeness, eigenvector, PageRank, k-core) are defined solely as functions of the adjacency structure of a graph and, by construction, contain no term for hierarchical level, dependency direction, or the horizontal-versus-ve...
