Constitutional Execution Infrastructure

Chapter 16 — Reference Architecture

This chapter combines every major CEI component into a single executable platform for governed execution.

Architecture is the structure of responsibility between components.

Architectural Layers

Execution Flow

1. Receive request
2. Authenticate identity
3. Resolve authority
4. Collect evidence
5. Load policy
6. Evaluate admissibility
7. Make constitutional decision
8. Execute if permitted
9. Write immutable event
10. Update projections
11. Enable replay

Conclusion

The CEI reference architecture integrates governance, execution, immutable evidence, replay, and projections into a unified constitutional execution platform.
