PURPOSE
    Define a formal AI-readable ontology for Prosthetics, including
    prosthetic devices, users, anatomical interfaces, sockets, liners,
    suspension systems, joints, feet, hands, terminal devices, structural
    components, sensors, actuators, control systems, alignment, fit,
    biomechanics, loads, gait, comfort, function, materials, fabrication,
    adjustment, testing, maintenance, provenance, uncertainty, confidence
    and recursive prosthetics reasoning.

CORE_DEFINITION
    Prosthetics is the biomedical and rehabilitation engineering domain
    concerned with designing, fitting, controlling, evaluating and
    maintaining artificial devices that replace or support missing body
    structures or functions through engineered mechanical, material,
    sensory and control interfaces.

    Critical Distinction
        Prosthetics reasoning must distinguish socket fit from alignment,
        suspension from socket fit, device function from user functional
        outcome and sensor signals from validated user intent. Device
        version, prosthetic level, anatomical side, component configuration,
        alignment, calibration, interface conditions, testing and
        maintenance provenance must remain explicit.

RECOMMENDED_AI_SUMMARY
    Prosthetics applies biomedical, mechanical and control engineering to
    artificial devices that replace or support missing body structures or
    functions. Reliable reasoning preserves prosthetic level and side,
    socket and suspension configuration, alignment, component and sensor
    state, interface loading, control mapping, test evidence and
    maintenance history while distinguishing bench performance from
    demonstrated user functional outcomes.
