Measurement Boundaries of Condition-Aware Mental-Demand Scoring: MOCAS-S3-v2 Frozen Analysis Records and Code

Frozen analysis records and implementation snapshots accompanying “Measurement Boundaries of Condition-Aware Mental-Demand Scoring”. Records cover participant-held-out evaluation of condition-only and three-proxy scoring families in overlapping MOCAS cohorts, frozen LOSO and repeated grouped five-fold splits, out-of-fold predictions, fitted parameters, selection records, sign-convention sensitivity, conditional paired intervals and within-participant shuffle diagnostics. These records support computational traceability; they do not establish mental-state measurement validity. Raw MOCAS signals are not included; MOCAS access/redistribution follows its agreement. Derived shareable records are deposited as a draft pending final license confirmation.
