State Transition Protocol
A state transition protocol is the agreed plan for moving a system from how it works now to how it will work next: the order of the steps, who owns each decision, how the new arrangement is verified as actually working, and how to get back if it doesn't. In most workplaces the same thing is called a change management plan, a cutover plan, or a runbook.

In plain language
A safe change needs more than a target state. The protocol says what happens in what order, who owns each decision, how the new state is verified, and how to return if the transition fails.
Why it matters
Ambiguous transitions create partial changes, split assumptions, and unsafe recovery. An explicit protocol makes the change observable and reversible.
Example
A database cutover specifies readiness checks, the migration sequence, owner signoffs, traffic switching, success measures, and the conditions for rolling back.
Common misconception
A state transition protocol is not merely a deployment checklist. It includes authority, verification, failure handling, and evidence that the new state is real.
