Cluster
A group of droughts with similar depth that form a structural neighborhood inside the table.
Why It Matters
Clusters reveal local concentration and can signal compression or fragmentation phases.
How Stepzero Uses It
Depth neighborhoods are monitored to detect converging pressure bands.
Example
Several droughts within a narrow depth range may form a top-table cluster.
