Characterize the ordering of harms from different skill-bank perturbations

Characterize the relative severity of harmful skill rewrites and meaning-preserving rewrites across perturbation axes beyond the ordering predicted by the minimal linear-Gaussian construction.

Background

The minimal linear-Gaussian construction predicts that a harmful rewrite, modeled as reversing the surface-form channel, causes greater degradation than a meaning-preserving rewrite. The authors explicitly state that this ordering was not tested empirically and that finer orderings among the perturbation axes remain unresolved.
