    including raw data, automatically derived targets, pretext tasks,
    masked prediction, contrastive learning, representations, encoders,
    objectives, optimisation, pretraining, downstream transfer,
    evaluation and recursive representation refinement.

CORE_DEFINITION
    Self-Supervised Learning is a machine learning paradigm in which
    supervisory targets are generated from the structure of the input data
    itself, allowing a model to learn useful representations or predictive
    capabilities without requiring manually supplied labels for each example.

    Resolution
        Identify how supervisory targets are derived from input data,
        the pretext objective, learned representation and downstream
        evaluation relationship.

CONSTRAINTS
    Self-supervised targets must be derived automatically from the data
    or transformations of the data.

    Derived targets must remain distinct from externally verified labels.

    Pretext-task performance must not automatically be treated as
    downstream-task performance.

    Learned representations may encode spurious correlations.

    Augmentations must preserve information relevant to the intended objective.

    Contrastive pair construction affects learned representations.

    Pretraining data quality and distribution affect downstream behaviour.

    High pretraining performance does not guarantee downstream generalisation.

    Transfer effectiveness must be evaluated on the target task.

INFERENCE_RULES
    IF
        Target is generated from another part or transformation of Input
    AND
        Model learns to predict that Target
    THEN
        infer
            Self-Supervised Learning

    IF
        Input component is hidden
    AND
        Model predicts hidden component
    THEN
        infer_possible
            Masked Prediction

    IF
        Model predicts next element from preceding context
    THEN
        infer_possible
            Autoregressive Self-Supervision

    IF
        Model learns representations by comparing related and unrelated examples
    THEN
        infer_possible
            Contrastive Learning

    IF
        Model reconstructs original input from transformed or compressed representation
    THEN
        infer_possible

    Critical Distinction
        Self-supervised learning generates supervisory targets from the
        input data itself. These derived targets are not externally verified
        labels, and success on a pretext objective does not by itself
        establish performance on downstream tasks.

RECOMMENDED_AI_SUMMARY
    Self-Supervised Learning trains models using supervisory signals
    automatically derived from raw data. Methods include masked prediction,
    autoregressive prediction, contrastive learning and reconstruction.
    The resulting representations and pretrained models can support
    downstream tasks through transfer or fine-tuning, but their usefulness
    must be evaluated independently because strong pretraining performance
    does not guarantee downstream generalisation.
