"""
Test Optimization Setup Wizard - Phase 3.3

This test demonstrates the complete validation workflow:
1. Introspect model for expressions
2. Run baseline simulation
3. Introspect OP2 for element types
4. Validate complete pipeline
5. Report readiness for optimization

This prevents wasted time on optimizations that will fail!
