ES-112 — Deployment and Transition¶
You are here¶
ES-111 confirmed that the approved operational scope can be supported, monitored, limited, stopped, and reviewed.
ES-112 performs the controlled deployment and transition.
Deployment is not merely copying files, publishing a build, or pushing a button. Deployment changes the state of the system, the environment, and the people who interact with it. Transition is the human and operational handoff that makes deployment understandable, supportable, observable, and reversible.
Why this stage exists¶
Teams often treat deployment as a technical action only.
That creates predictable failure:
- release limits are not enforced;
- wrong users gain access;
- sample data rules are ignored;
- disabled features become active;
- rollback is not credible;
- users are not told the limits;
- support owners are not ready;
- deployment evidence is missing;
- post-deployment checks are skipped.
ES-112 prevents those failures by making deployment and transition controlled engineering activities.
The engineering question¶
Can the approved scope be deployed and transitioned without expanding risk, losing evidence, confusing users, or weakening operational controls?
What you will produce¶
ES-112 produces deployment and transition artifacts under:
docs/deployment/
Required artifacts:
deployment_overview.md
deployment_scope.md
deployment_plan.md
environment_readiness_check.md
deployment_execution_record.md
transition_communication.md
access_and_data_transition_record.md
rollback_validation_record.md
post_deployment_check.md
deployment_readiness_summary.md
Templates should be copied from:
template-library/deployment/
Completed reference examples, when available, should be reviewed under:
examples/lmu-coicp/deployment/
What good looks like¶
Good ES-112 evidence shows what was deployed, where it was deployed, who may access it, what data is allowed, which features are enabled or disabled, what checks were performed, what users and support roles were told, how rollback or stop was validated, what post-deployment checks showed, and whether ES-113 can begin.
A deployment without transition is not complete.
A deployment without evidence is not reviewable.
Deployment must preserve scope¶
Deployment must not expand beyond approved release and operational boundaries.
If ES-110 approved internal engineering review only, deployment must not quietly become a pilot. If AI functionality was disabled, deployment must not enable it. If only sample data was approved, deployment must not accept real operational data.
Deployment is not a loophole.
Relationship to ES-111¶
ES-111 defines operational readiness.
ES-112 executes deployment and transition within that approved boundary.
Do not expand scope during deployment. If scope must change, return to ES-110 and ES-111.
Relationship to ES-113¶
ES-113 should not have to guess what was deployed, who has access, what data is allowed, what features are disabled, what monitoring exists, what rollback path is credible, or what users were told.
ES-112 provides the deployment evidence needed for operations and monitoring to begin responsibly.
Lifecycle chain¶
ES-112 continues the ETIS lifecycle chain:
Question

Evidence

Decision

Repository Artifact

Next Stage
For ES-112, the question is whether approved scope can be deployed and transitioned safely. The evidence is the deployment and transition package. The decision is whether operations and monitoring can begin. The repository artifact is stored under docs/deployment/. The next stage is ES-113.
AI may help draft deployment checklists, review transition messages, identify deployment risks, compare scope against release conditions, and summarize deployment evidence. AI must not execute deployment decisions or approve scope changes.
Do not treat a successful technical deployment as a successful transition. Users, support, monitoring, access, data, and stop conditions must also be ready.
Deployment is where controlled engineering evidence becomes controlled operational exposure.
