The Model
A reference model for keeping state change authoritative when people, applications and AI agents can all propose what should happen next.
An enterprise system usually has no shortage of information. It has reports, documents, queues, search indexes, dashboards, event streams and, increasingly, models that can combine all of them into a plausible recommendation. The difficult question arrives one step later: who is allowed to turn that recommendation into a change of state?
The Governed State Contract model answers plainly. Consumers may propose actions. The system responsible for the affected state decides whether to execute them.
That distinction is easy to lose in a UI-first architecture. A screen gathers data, applies a little validation and sends a representation to a generic endpoint. Another consumer—a mobile app, integration or agent—then has to reproduce those rules or find a way around them. The apparent convenience is purchased by distributing the meaning of the business process across callers.
Reasoning and authority are different jobs
The model separates work that is often bundled together. Analytical context is broad, read-oriented and useful for judgement. It may include a graph of relationships, a vector search result, a risk score or a history assembled from several systems. Operational authority is narrower and more demanding: it knows the current state, the applicable policy, the permissions, the invariants and the consequences of a proposed change.
An agent can use broad context to suggest that an issue is ready to close. A user interface can present the same suggestion to a human. Neither suggestion is the closure itself. The issue-management authority re-reads the current issue, checks the relevant conditions and either accepts the request or explains why it cannot.
The architecture in one line
Consumers observe context and propose intent.
Operational authorities validate, decide and execute.
Audit and events record what happened and refresh context.
The model is not an argument for putting all intelligence in one place. Intelligence and context can be distributed where they are useful. It is an argument for keeping the authority to change important state in the capability that can verify the decision at the moment it is made.
The rest of this reference explains the model’s moving parts: operational authority , analytical context , governed actions and the contracts through which consumers encounter them.
