Collapse Index (CI) & Structural Retention Index (SRI): Advanced diagnostic frameworks for bounded, lightweight evaluation of AI model instability beyond accuracy, revealing hidden brittleness in production systems!

Public validation of SRI (Structural Retention) and CI (Collapse Index) metrics on AG News dataset: 90.4% accuracy, 9.2% flip rate, revealing model brittleness beyond standard benchmarks with AUC 0.874!

Public validation of Collapse Index (CI) on SST-2 dataset: 42.8% flip rate, AUC 0.698. Reveals model brittleness beyond 90%+ accuracy under perturbations!
