Nature Communications, Published online: 31 May 2026; doi:10.1038/s41467-026-73939-8 Understanding the structural origins of stability in disordered solids is essential for predicting mechanical failure and manipulating their properties, yet the inherent disorder complicates this analysis. This study identifies stabilizing bonds as critical structural features that govern stability across a spectrum from marginal to ultra-stable disordered solids, providing a unified framework for understanding
