#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let config = ForensicConfig::nis2_compliant();
    let mut auditor = BlackBoxAuditor::new(config).await?;
    
    auditor.start_immutable_logging().await?;
    auditor.enable_quantum_signatures().await?;
    
    auditor.run().await?;
    Ok(())
}
```
