CORE_DEFINITION
    Biomedical Engineering is the engineering discipline that applies
    engineering, physical, computational and biological principles to
    understand biological systems and to design technologies, devices,
    materials and systems for healthcare, diagnosis, monitoring,
    rehabilitation and therapy.

    Critical Distinction
        Biomedical-engineering reasoning must distinguish medical devices
        from medical treatments, biosignals from diagnoses, sensor readings
        from physiological truth and verification from validation. Device
        version, intended use, biological context, calibration, measurement
        conditions, test methods, safety evidence and provenance must
        remain explicit.

RECOMMENDED_AI_SUMMARY
    Biomedical Engineering applies engineering principles to biological
    systems and healthcare technologies, including medical devices,
    biomaterials, sensors, imaging, biomechanics and rehabilitation.
    Reliable reasoning preserves intended use, device and software version,
    biological context, measurement calibration, engineering requirements,
    verification, validation and risk evidence while avoiding unsupported
    conversion of biosignals or engineering measurements into clinical
    diagnoses or conclusions.
