Abstract

This paper formalizes a Φ-split extension of the Compression-Resonance Thermodynamic Index (CRTI) to diagnose structural overcompression in complex adaptive systems. Feedback permeability is decomposed into external and internal channels and transformed via a sigmoid saturation function. A logarithmic compression ratio (T_adj) provides mathematical robustness under low-permeability conditions. The framework is empirically falsifiable and designed as an early-warning model for systemic fragility.

Discussions

• When structural complexity outpaces feedback permeability, systems do not fail from chaos … they fail from overcompression. I formalized a Φ-split, sigmoid-transformed CRTI model as a falsifiable ea [bsky, 2 points, 0 comments]
