Toward ABS-1.1: A Specification for Constraint-Induced Structural Integrity Metrics and the Tourniquet Effect Hypothesis

ABS-1.1 extends the Attractor Behavior Scoring framework (ABS v1.0) by adding eight metrics targeting both positive constraint-induced structural gain and structural integrity under adversarial pressure. It introduces the Constraint Gain Module (Delta-Retention, Structure Drift, False Order Risk, Framework Overfit) and Structural Integrity Module (Structural Validity, Conflict Density Tolerance, Pollution Resistance, Latent Structure Retention). Pilot evidence from four-round closed-loop experiments (EXP-050) supports the Tourniquet Effect hypothesis: constrained outputs maintain structural integrity under pressure better than unconstrained outputs.
