# Demo 3: Full-Stack Production Architecture

## Purpose

This demo shows a **production-ready** implementation of Agent Lightning + Tractatus integration with:
- Complete observability (metrics, logging, tracing)
- Error handling and recovery
- Scaling considerations
- Deployment architecture
- Monitoring dashboards

## Features

### 1. Governance Features
- ✓ Real-time boundary enforcement
- ✓ Stakeholder deliberation workflows
- ✓ Constraint validation
- ✓ Audit trail (all decisions logged)
- ✓ Emergency stop mechanisms

### 2. Performance Features
- ✓ RL-based optimization
- ✓ Continuous learning
- ✓ Multi-agent coordination
- ✓ Horizontal scaling
- ✓ Load balancing

### 3. Observability Features
- ✓ Metrics: Performance, governance, system health
- ✓ Tracing: Request flows, decision paths
- ✓ Logging: Structured, searchable
- ✓ Dashboards: Real-time monitoring

### 4. Production Features
- ✓ Error recovery
- ✓ Circuit breakers
- ✓ Rate limiting
- ✓ Health checks
- ✓ Graceful degradation

## Use Cases

This architecture supports:
1. **High-throughput AI applications** (e.g., content moderation at scale)
2. **Safety-critical systems** (e.g., healthcare, finance)
3. **Multi-stakeholder platforms** (e.g., social media, marketplaces)
4. **Regulated industries** (e.g., legal, government)

## Running the Demo

### Prerequisites
```bash
# Docker & Docker Compose (for observability stack)
docker --version
docker-compose --version

# Python environment
python3 -m venv venv
source venv/bin/activate
pip install -r requirements.txt
```

### Start Observability Stack
```bash
# Start Prometheus, Grafana, Jaeger
docker-compose up -d
```

### Run System
```bash
python main.py
```

### Access Dashboards
- **Grafana**: http://localhost:3000 (admin/admin)
- **Prometheus**: http://localhost:9090
- **Jaeger**: http://localhost:16686
