This annex provides a structured roadmap for introducing Constitutional Execution Infrastructure (CEI) into existing software platforms. The guidance is technology-neutral and intended to reduce migration risk through incremental adoption.
| Phase | Objective | Deliverables |
|---|---|---|
| Assessment | Understand the current environment. | Architecture inventory, governance gap analysis. |
| Preparation | Define governance policies and responsibilities. | Policy repository, authority model. |
| Pilot | Govern a limited workflow. | Runtime, ledger, replay proof-of-concept. |
| Expansion | Extend governance to additional services. | Integrated APIs, projections, monitoring. |
| Optimization | Improve performance and operational maturity. | Benchmark results, operational runbooks. |

Enterprise Rollout
| Indicator | Example Measure |
|---|---|
| Governed Coverage | Percentage of critical workflows under governance. |
| Replay Readiness | Successful reconstruction of historical decisions. |
| Policy Compliance | Reduction in unmanaged exceptions. |
| Operational Stability | No increase in service disruption during rollout. |
A phased migration enables organizations to introduce governance capabilities while preserving operational continuity and creating measurable evidence of progress.
