|
||||
```
|
||||
|
||||
### Flow Steps:
|
||||
1. **User Query Input**: Receive command/query from user/agent
|
||||
2. **Layer0 Classification**: Pre-execution security assessment
|
||||
3. **Routing Decision**: Determine allow/block/redirect action
|
||||
4. **Shadow Evaluation**: ML-based threat assessment
|
||||
5. **Oracle Answer**: Security decision support via MCP
|
||||
6. **Preboot Logging**: Security event recording
|
||||
7. **Execution/Block**: Allow safe operations, block dangerous ones
|
||||
8. **Audit Trail**: Comprehensive security event tracking

|
||||
|
||||
### 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.
