Metric: betweenness centrality, normalized 0–1, computed across the full corpus graph (n=1,959 words, 150 nodes, 1,201 edges, modularity 0.379). Top 4 degrees from InfraNodus top_influential_nodes; ranks 5–15 degrees computed across the edge set. health, woman, aha, and consumer together carry roughly half the bridging weight in the corpus — the four institutional and economic vocabularies the Reframe must hold.
