"""Test script for RobustMotorCADSolver - Step 1: Connection and variable probing.

This script tests:
1. Motor-CAD connection (open_new_instance=True + set_visible=True)
2. Model loading
3. Variable probing (get common variable names)
4. Parameter write-back verification
5. Single magnetic calculation
6. Result export and parsing

All source is ASCII only.
