Falsifiable Signatures of Hybrid-Contour Stress

Status. Methodological note within a hypothetical framework. This text does not claim that current AI deployments are already in a state of hybrid-contour stress. It isolates observable signatures that, under the Acta Universi (AU) reading, should appear when mutual coherence is falling or when irreversibility is accumulating faster than steerability. The aim is to make the structural claims of the recent notes vulnerable to data.
