# Shared-Basis Stability Analysis

This folder builds figures for the claim that subgroup size is more stable
than internal profile only after both branches are projected onto the same
support-oriented basis.

The shared metric used here is:

- `support3_score = mean(key_set_score, row_count_score, column_score)`

Outputs:
