## Execution: Validating Generated YAML

    """Load YAML into OrcFxAPI and check for errors."""
    model = OrcFxAPI.Model()
    try:

        error_msg = str(e)
        errors = [error_msg]

        # Diagnose common YAML gotchas
        if "Change not allowed" in error_msg:
            errors.append("Likely dormant property issue — check mode-setting property order")
        if "not a valid" in error_msg and "name" in error_msg.lower():
