PRESPECIFIED RESEARCH PROTOCOL Application of Isomorphic Triangulation to the Study of Algorithmic Bias in Recidivism Risk Assessments: The COMPAS Case

Frozen research protocol (pre-registration) for the empirical evaluation of Isomorphic Triangulation (IT) applied to the COMPAS algorithmic bias case (ProPublica/Northpointe/Chouldechova). Defines the immutable experimental setup: independent units of analysis ($S_1, S_2, S_3$), the operational V/R/C/T/F model, the rupture test, the exploratory Isomorphic Correspondence Index ($ICI \\pm U$), and explicit falsification criteria prior to corpus coding
