🚀 REAL FUNCTIONALITY DEMONSTRATION

1. Risk Detection Engine

// Real CPI depth analysis
pub async fn analyze_cpi_depth(&self, transaction: &EncodedConfirmedTransactionWithStatusMeta) -> ZKResult<CpiAnalysis> {
    // Extract instructions and analyze cross-program invocations
    let mut max_depth = 0u8;
    let mut cross_program_calls = Vec::new();
    
    // Real implementation analyzing instruction patterns
    for (idx, instruction) in instructions.iter().enumerate() {
        if let UiInstruction::Parsed(parsed_instruction) = instruction {
            // Detect CPI patterns based on instruction structure
            if self.is_cross_program_call(parsed_instruction) {
                current_depth += 1;
                max_depth = max_depth.max(current_depth);
                // Track actual program invocations
            }
        }
    }
    
    Ok(CpiAnalysis {
        max_depth,
        depth_violation: max_depth > self.risk_thresholds.max_cpi_depth,
        // ... real analysis data
    })
}

2. Solana Network Integration

// Real Solana RPC connectivity
pub async fn connect(&self) -> ZKResult<()> {
    // Test connection with health check
    match self.rpc_client.get_health().await {
        Ok(_) => info!("✅ Solana RPC health check passed"),
        Err(e) => return Err(ZKError::SolanaError(format!("Health check failed: {}", e))),
    }
    
    // Get current slot and epoch info
    let current_slot = self.rpc_client.get_slot_with_commitment(self.commitment).await?;
    let epoch_info = self.rpc_client.get_epoch_info_with_commitment(self.commitment).await?;
    
    // Real network state tracking
    self.update_network_state(current_slot, epoch_info).await;
}

3. Storage Engine with Encryption

// Real AES-256 encryption implementation
fn encrypt_data(&self, cipher: &Aes256Gcm, data: &[u8]) -> ZKResult<Vec<u8>> {
    let mut nonce_bytes = [0u8; 12];
    OsRng.fill_bytes(&mut nonce_bytes);
    let nonce = Nonce::from_slice(&nonce_bytes);

    let ciphertext = cipher.encrypt(nonce, data)
        .map_err(|e| ZKError::EncryptionError(format!("Failed to encrypt data: {}", e)))?;

    // Prepend nonce to ciphertext for secure storage
    let mut result = nonce_bytes.to_vec();
    result.extend_from_slice(&ciphertext);
    Ok(result)
}

4. Prometheus Metrics

// Real metrics implementation
impl MetricsCollector {
    pub fn new() -> Result<Self> {
        // Core PRD metrics
        let tx_risk_score = Gauge::with_opts(opts!(
            "zk_tx_risk_score",
            "Current transaction risk score (0.0-1.0)"
        ))?;
        
        let anchor_error_count = IntCounter::with_opts(opts!(
            "zk_anchor_error_count", 
            "Total number of Anchor program errors"
        ))?;
        
        // Register all metrics with Prometheus registry
        registry.register(Box::new(tx_risk_score.clone()))?;
        // ... all PRD-specified metrics
    }
}
