Grade 5 titanium string → bone saddle → aluminium bridge shoe → annular bridge → 5052-H32 soundboard/body → restrained C655 roof response.

This viewer represents the approved prototype construction definition and its physical load paths. Gear teeth are engineering visualization geometry rather than manufacturing involute CAD. Rotor torque, bearing drag, governor calibration and final acoustic modal response remain prototype-measurement items before production release. Foundation engineering remains outside this model.
