🔧 Integration Points

Sentinel Client

  • Supports Claude (Anthropic), GPT (OpenAI), Gemini (Google), DeepSeek
  • Automatic retry logic with exponential backoff
  • Health monitoring with circuit breaker pattern
  • Metrics tracking via DVA.LITE

Human Review Queue

  • Automatic enqueueing for low-GI answers
  • Email and Slack notifications
  • Approval workflow with ECHO cache integration
  • Priority-based routing

Security Logging

  • Critical event detection
  • Automatic alerting
  • Audit trail for all security events
  • Integration with notification system

DVA.LITE Integration

  • Buffered metric publishing
  • Automatic batching and flushing
  • Support for GI scores, consensus, drift, validation, and security events
  • Graceful degradation if DVA.LITE unavailable

🚀 Next Steps

1. Environment Configuration

Create .env file with: 

# API Keys
OPENAI_API_KEY=sk-...
ANTHROPIC_API_KEY=sk-ant-...
GOOGLE_API_KEY=...
DEEPSEEK_API_KEY=sk-...

# Database
DATABASE_URL=postgresql://user:pass@localhost:5432/mobius_echo
ECHO_ADMIN_KEY=$(openssl rand -base64 32)

# Monitoring
DVA_LITE_URL=https://dva.lite.mobius.systems
DVA_LITE_API_KEY=...

# Notifications
SMTP_HOST=smtp.sendgrid.net
SMTP_PORT=587
SMTP_USER=apikey
SMTP_PASS=...
SMTP_FROM=noreply@mobius.systems
SECURITY_ALERT_EMAILS=security@mobius.systems
SLACK_WEBHOOK_URL=https://hooks.slack.com/...

# Application
APP_URL=https://api.mobius.systems
NODE_ENV=production
PORT=3000

2. Database Setup

# Run migrations
psql $DATABASE_URL -f infra/db/migrations/001_create_echo_layer.sql

# Verify extensions
psql $DATABASE_URL -c "SELECT * FROM pg_extension WHERE extname IN ('uuid-ossp', 'vector');"

3. Install Dependencies

npm install @anthropic-ai/sdk openai @google/generative-ai nodemailer pg @types/pg

4. Test Integration

# Run health check
curl http://localhost:3000/health

# Check sentinel health
curl -H "X-Admin-Key: $ECHO_ADMIN_KEY" http://localhost:3000/health/detailed

# Get Prometheus metrics
curl -H "X-Admin-Key: $ECHO_ADMIN_KEY" http://localhost:3000/metrics

🔒 Safety Guarantees

  1. Zero-Drift: Models never modify their own weights
  2. Hallucination-Proof: All facts require multi-source verification
  3. Constitutional Governance: GI thresholds enforce alignment
  4. Human Sovereignty: Low-GI answers require human approval
  5. Immutable Audit: Civic Ledger provides cryptographic provenance

📈 Monitoring

  • Health Endpoints: /health, /health/detailed, /metrics
  • DVA.LITE: Automatic telemetry for all operations
  • Security Events: Critical alerts via email/Slack
  • Sentinel Health: Circuit breaker prevents cascade failures
