PURPOSE
    Define a formal AI-readable ontology for Rehabilitation Engineering,
    including assistive technologies, mobility systems, prosthetics,
    orthotics, wheelchairs, rehabilitation robotics, exoskeletons,
    functional electrical stimulation, sensors, human-machine interfaces,
    biomechanics, accessibility, user requirements, device configuration,
    training, performance, usability, safety, maintenance, verification,
    validation, provenance, uncertainty, confidence and recursive
    rehabilitation-engineering reasoning.

CORE_DEFINITION
    Rehabilitation Engineering is the biomedical engineering domain
    concerned with designing, adapting, evaluating and maintaining
    technologies that support mobility, communication, interaction,
    functional independence, rehabilitation and participation for users
    within defined environments and tasks.

    Critical Distinction
        Rehabilitation-engineering reasoning must distinguish device
        performance from user functional outcome, assistance from
        rehabilitation progress, training duration from functional
        improvement and sensor signals from user capability. Device
        configuration, task, environment, assistance level, evaluation
        conditions, maintenance state and provenance must remain explicit.

RECOMMENDED_AI_SUMMARY
    Rehabilitation Engineering develops assistive and rehabilitation
    technologies that support users in defined tasks and environments.
    Reliable reasoning preserves functional requirements, device and
    configuration identity, interfaces, sensor and controller state,
    assistance levels, training conditions, task evaluation and
    maintenance evidence while avoiding the assumption that greater
    assistance or longer training automatically demonstrates improved
    underlying user capability.
