    // Process Managed Space atoms with PQC
    let atom = Atom::new(0x12345678, [0x42; 28]);
    
    // Generate PQC signature
    let signature = ghost_node.generate_signature(
        &atom, 
        Some(PqcAlgorithm::Dilithium { variant: DilithiumVariant::Dilithium2 })
    ).await?;
    
    // Verify PQC signature
    let verified = ghost_node.verify_signature(&atom, &signature).await?;
