Governance-First Predictive Modelling for 'Gazepoint' Research // Provides governance-first infrastructure for leakage-resistant predictive modelling and validation using 'Gazepoint'-derived research data. Supports explicit task and role declarations, feature-provenance manifests, group-aware holdout splitting and repeated resampling, fold-local preprocessing, governed model engines, discrimination and calibration metrics, bootstrap uncertainty, external-validation reports, model cards, and reproducibility reports. Intended only for explicitly observed, non-sensitive outcomes and declared scientific purposes. Use is prohibited for person identification, biometric authentication, health or protected-attribute inference, and direct or indirect inference of emotion, stress, personality, deception, cognition, comprehension, intent, or other mental states.
