The README opens with

Let an agent make a bounded choice without handing it control. Jev recommends. Your harness still checks permissions and executes.

Without Jev With Jev --- --- Your harness follows its existing path to choose a capability. The harness can ask jevroute to choose from a bounded set it supplies. Your harness owns permissions, approvals, and execution. Your harness still owns permissions, approvals, and execution. Execution results stay in the host's normal workflow. The host can attach the result to the decision with jevrecordexecution and replay cases offline.
