REAL PLATINUM-ROAD VALIDATION: ACTUAL CODE VERIFICATION
======================================================

This script validates that the platinum-road deliverables are actually implemented
as real working code with numerical outputs, not just documentation claims.

Verifies:
1. Core functions exist and execute without errors
2. Numerical outputs are reasonable and finite
3. Data export files are created with actual content
4. Mathematical properties are satisfied (gauge invariance, classical limits, etc.)
