cluster-stats-sizes-sum-to-input
IN premise
The `cluster_sizes` list in the stats dict returned by `cluster_beliefs` always sums to the total number of input beliefs, enforcing that every belief is assigned to exactly one cluster.
Summary
Every belief that goes into the clustering process comes out assigned to exactly one cluster — none are lost and none are double-counted. This means the cluster sizes always add up to the total input count, so you can trust the clustering as a complete partition of the belief set.
