How could a simulated environment represent review actions and their permitted transitions?

A simulated environment could expose actions such as `open_review`, `request_evidence`, `submit_assessment` and `record_authorised_decision`. Each action can specify permitted roles, required inputs and the states from which it is valid.

The underlying records might include `review_id`, `status`, `assigned_role`, `evidence_bundle_id` and `decision_id`. A transition table can require an assessment before decision recording and prohibit further assessment edits after the decision has been finalised.

Structured errors matter. A response such as `missing_required_evidence` should identify the unmet precondition, while `role_not_permitted` should explain that the action requires a different authority. These responses create meaningful recovery tasks for the agent.

The environment can return a transition receipt containing the action identifier, resulting state and affected record links. Developers can use that receipt to reconcile an agent's claimed progress with actual system state.

MirrorFirm could scope these behaviours into generated environment state and tool contracts. The buyer should identify which transitions need simulation and which external systems remain represented by fixed responses, so the integration boundary is explicit.
