Quick Start

use aimds_core::{Config, PromptInput};
use aimds_response::ResponseSystem;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Initialize response system
    let config = Config::default();
    let responder = ResponseSystem::new(config).await?;

    // Mitigate detected threat
    let input = PromptInput::new("Malicious input", None);
    let analysis = analyzer.analyze(&input, None).await?;

    let result = responder.mitigate(&input, &analysis).await?;

    println!("Mitigation applied: {:?}", result.action);
    println!("Effectiveness: {:.2}", result.effectiveness_score);
    println!("Latency: {}ms", result.latency_ms);
    println!("Can rollback: {}", result.can_rollback);

    Ok(())
}

Mitigation Strategies

Available Strategy Types

1. Block: Completely deny the request
2. Rate Limit: Throttle request frequency
3. Sanitize: Remove malicious content
4. Quarantine: Isolate for manual review
5. Alert: Notify security team
6. Log: Record for analysis
7. Transform: Modify request safely

Strategy Selection

use aimds_response::{AdaptiveMitigator, MitigationStrategy};

let mitigator = AdaptiveMitigator::new();

// Automatic strategy selection based on threat
let strategy = mitigator.select_strategy(&threat_analysis).await?;

match strategy {
    MitigationStrategy::Block => {
        // High-severity threat, block immediately
    }
    MitigationStrategy::RateLimit { limit, window } => {
        // Moderate threat, throttle
    }
    MitigationStrategy::Sanitize => {
        // Low threat, clean input
    }
    _ => {}
}

Effectiveness Tracking

// Apply mitigation and track effectiveness
let result = responder.mitigate(&input, &analysis).await?;

// Meta-learning updates strategy effectiveness
println!("Success rate: {:.2}%",
    mitigator.get_strategy_effectiveness(&result.action) * 100.0);

// Adaptive selection uses historical effectiveness

Meta-Learning

25-Level Recursive Optimization

Uses the strange-loop crate for deep meta-learning:

use aimds_response::MetaLearning;

let meta = MetaLearning::new();

// Learn from mitigation outcomes
meta.learn_from_incident(&incident).await?;

// Extract patterns across multiple incidents
let patterns = meta.extract_patterns(&incidents).await?;

// Optimize strategy selection
meta.optimize_strategies(&patterns).await?;

println!("Optimization level: {}/25", meta.current_level());

Pattern Learning

// Learn from successful mitigations
for incident in successful_incidents {
    meta.learn_from_incident(&incident).await?;
}

// Extract common patterns
let patterns = meta.extract_patterns(&all_incidents).await?;

for pattern in patterns {
    println!("Pattern: {:?}", pattern.pattern_type);
    println!("Effectiveness: {:.2}", pattern.effectiveness);
    println!("Frequency: {}", pattern.occurrences);
}

Rollback Management

Automatic Rollback

use aimds_response::RollbackManager;

let rollback = RollbackManager::new();

// Apply mitigation with rollback capability
let action = responder.mitigate(&input, &analysis).await?;
rollback.push(action.clone()).await?;

// If mitigation fails, rollback
if mitigation_failed {
    rollback.rollback_last().await?;
}

// Rollback multiple actions
rollback.rollback_all().await?;

Rollback History

// Query rollback history
let history = rollback.get_history().await?;

for (idx, action) in history.iter().enumerate() {
    println!("Action {}: {:?} at {}",
        idx, action.action_type, action.timestamp);
}

// Selective rollback
rollback.rollback_action(&specific_action_id).await?;

Audit Logging

Comprehensive Audit Trail

use aimds_response::AuditLogger;

let audit = AuditLogger::new();

// Log mitigation start
audit.log_mitigation_start(&input, &analysis).await?;

// Log mitigation completion
audit.log_mitigation_complete(&result).await?;

// Query audit logs
let logs = audit.query_logs(
    Some(start_time),
    Some(end_time),
    Some(ThreatSeverity::High)
).await?;

// Export to JSON
let json = audit.export_json().await?;

Statistics

// Get audit statistics
let stats = audit.get_statistics().await?;

println!("Total mitigations: {}", stats.total_mitigations);
println!("Success rate: {:.2}%", stats.success_rate * 100.0);
println!("Average latency: {}ms", stats.avg_latency_ms);

// Per-strategy statistics
for (strategy, effectiveness) in stats.strategy_effectiveness {
    println!("{:?}: {:.2}%", strategy, effectiveness * 100.0);
}

Usage Examples

Full Response Pipeline

use aimds_response::ResponseSystem;
use aimds_core::{Config, PromptInput};

let responder = ResponseSystem::new(Config::default()).await?;

// Mitigate threat
let input = PromptInput::new("Malicious content", None);
let analysis = analyzer.analyze(&input, None).await?;

let result = responder.mitigate(&input, &analysis).await?;

println!("Action: {:?}", result.action);
println!("Effectiveness: {:.2}", result.effectiveness_score);

// Rollback if needed
if result.should_rollback() {
    responder.rollback_last().await?;
}

Context-Aware Mitigation

use aimds_response::{MitigationContext, ResponseSystem};

let context = MitigationContext::builder()
    .request_id("req_123")
    .user_id("user_456")
    .session_id("sess_789")
    .threat_severity(ThreatSeverity::High)
    .metadata(serde_json::json!({
        "ip": "192.168.1.1",
        "user_agent": "Mozilla/5.0"
    }))
    .build();

let result = responder.mitigate_with_context(&input, &analysis, &context).await?;

Meta-Learning Integration

// Initialize with meta-learning
let mut responder = ResponseSystem::new(config).await?;

// Process incidents and learn
for incident in incidents {
    let result = responder.mitigate(&incident.input, &incident.analysis).await?;

    // Meta-learning automatically updates strategy effectiveness
    responder.learn_from_result(&result).await?;
}

// Strategies adapt based on historical effectiveness

Use Cases

API Gateway Protection

Adaptive threat response for LLM APIs:

// Detect and respond to threats
let detection = detector.detect(&input).await?;
let analysis = analyzer.analyze(&input, Some(&detection)).await?;

if analysis.is_threat() {
    let result = responder.mitigate(&input, &analysis).await?;

    match result.action {
        MitigationAction::Block => return Err("Request blocked"),
        MitigationAction::RateLimit { .. } => apply_rate_limit(&input),
        _ => {}
    }
}

Multi-Agent Security

Coordinated response across agent swarms:

// Coordinate mitigation across agents
for agent in swarm.agents() {
    let analysis = analyzer.analyze(&agent.current_action(), None).await?;

    if analysis.is_threat() {
        let result = responder.mitigate(&agent.current_action(), &analysis).await?;
        swarm.apply_mitigation(agent.id, result).await?;
    }
}

Incident Response

Automated incident handling with rollback:

// Apply mitigation
let result = responder.mitigate(&input, &analysis).await?;

// Monitor effectiveness
tokio::time::sleep(Duration::from_secs(60)).await;

if !result.was_effective() {
    // Rollback and try different strategy
    responder.rollback_last().await?;

    let new_result = responder.mitigate_with_strategy(
        &input,
        &analysis,
        MitigationStrategy::Quarantine
    ).await?;
}
