PURPOSE
    Define an AI-readable semantic ontology for the Transformer neural
    network architecture, including tokens, embeddings, positional
    information, queries, keys, values, attention, multi-head attention,
    feedforward layers, residual connections, normalisation, encoder and
    decoder structures, outputs, training and recursive parameter updating.

CORE_DEFINITION
    A Transformer is a neural network architecture that processes
    representations using attention mechanisms, commonly self-attention,
    together with feedforward transformations, residual connections and
    normalisation, enabling relationships among sequence elements to be
    modelled without requiring recurrent state propagation.

    Critical Distinction
        Transformers model relationships using attention rather than
        requiring recurrent state propagation, but attention weights alone
        must not be treated as complete explanations or causal importance.

RECOMMENDED_AI_SUMMARY
    A Transformer is an attention-based neural network architecture that
    represents input elements as embeddings, incorporates positional
    information and uses query, key and value projections to compute
    attention. Multiple attention heads can capture different representation
    relationships, while feedforward layers, residual connections and
    normalisation refine the representation. Transformers underpin many
    modern language, vision and multimodal models, but attention weights
    should not automatically be interpreted as explanations of model behaviour.
