    rehabilitation systems, tissue engineering, diagnostics, therapeutic
    systems, requirements, design controls, verification, validation,
    biocompatibility, usability, risk, safety, provenance, uncertainty,
    confidence and recursive biomedical-engineering reasoning.

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

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

RECOMMENDED_AI_SUMMARY
    Biomedical Engineering applies engineering principles to biological
    systems and healthcare technologies through devices, biomaterials,
    sensors, imaging, biomechanics and rehabilitation systems. Reliable
    reasoning preserves intended use, device and software versions,
    biological context, calibration, requirements, verification,
    validation and risk evidence while avoiding unsupported conversion of
    engineering measurements or biosignal patterns into clinical
