```

### Flow Steps:
1. **Live State Monitoring**: Continuous Cloudflare API polling
2. **Invariant Validation**: Check against desired state + security policies
3. **Anomaly Detection**: Identify configuration drift or violations
4. **Drift Analysis**: Determine root cause and severity
5. **Auto Remediation**: Apply fixes via Safe MCP server
6. **Ops Notification**: Alert human operators if needed
7. **State Update**: Apply Terraform changes if remediation successful
8. **Re-validation**: Confirm invariants are restored

## 🎯 Key Operational Principles

### Separation of Concerns
- **MCP = Intent**: What should happen
- **Terraform = State**: What the desired state is
- **GitOps = Change**: How changes propagate
- **Layer0 = Security**: Whether actions are safe

### Deterministic Operations
- Same inputs → same outputs
- No ambient dependencies
- Explicit environment configuration
- Version-controlled everything

### Continuous Verification
- Real-time state validation
- Automated remediation
- Comprehensive audit trails
- Security classification at every step

These flows represent a **production-grade operational model** where each component has clear responsibilities and the system self-corrects when deviations occur.
