Compression
A phase where multiple high-rank droughts converge in depth, tightening the top of the table and increasing structural tension.

Glossary term
Compression is the tightening of top-table tension as high-rank droughts cluster together.
Why It Matters
Compression elevates competition among top droughts and often precedes sharp table transitions.
How Stepzero Uses It
Stepzero tracks top-band depth spread to detect compression and quantify rising structural tension.
Example
If top-five droughts sit within a narrow depth band, the table is in compression.
