Class: MobilityAidsItem

Mobility aids and assistive devices: wheelchairs, crutches, walking frames, hearing aids, orthotics, daily living aids. COICOP 06.1.3 (other medical products) and 06.2 (outpatient services, durable medical equipment). Open Eligibility "Assistive Technology" top-level category:

https://company.auntbertha.com/openeligibility/

Assessment: MobilityAssessmentEnum (structured safety and hygiene). A single enum captures structural soundness, functional state, and body-contact hygiene (used hearing aids, orthotics) — replacing the former separate boolean structural_integrity + functional_status slots that generated the problematic annotation-based approach. assessment_result required regardless of usage — new mobility aids can have manufacturing defects.

    - Due to a limitation in LinkML, the designates_type annotation was removed because
