Permutation-based null calibration correctly collapses scores to zero under Gaussian, Student-t, Laplace, and Gaussian mixture noise without requiring any distributional assumptions about the data-generating process

Summary

A specific statistical calibration check (permutation-based null calibration) gives the correct "nothing special is going on" result no matter what shape the background noise has — whether it's smooth, heavy-tailed, or lumpy. This means the system can rely on this test as a trustworthy baseline without first having to identify or assume the noise model, making it safe to apply broadly across different data sources.
