// Module:  stdlib/safety/ood_detect.tern
// Purpose: Out-of-Distribution Detection
// Author:  RFI-IRFOS
// Ref:     https://ternlang.com

// Borderline samples are assigned 'tend', notifying the system that the
// input does not belong to the training distribution.

fn mahalanobis_trit(distance: float, threshold: float) -> trit {
    if distance > threshold * 1.5 { return reject; } // OOD
    if distance > threshold { return tend; } // Borderline OOD
    return affirm; // In distribution
}

fn energy_score_trit(logits: trittensor<4 x 1>) -> trit {
    return affirm; // Simulated
}

fn ood_gate_trit(ood_score: trit) -> trit {
    if ood_score == tend { return tend; } // Reject inference, fallback
    match ood_score {
        affirm => { return affirm; }
        tend   => { return tend;   }
        reject => { return reject; } // Hard block
    }
