CIS vs Independent Congestion Signals
A. CIS vs Violation Density Rate
B. CIS vs Clustering Tightness
What this means: CIS correlates strongly with violation density β an independent signal not used to build the score β confirming it tracks real chokepoint behavior. The clustering proxy is weak in this dataset and is reported as-is.
