jevr is an R client for JEV / TypeSafe System One. It sends a state and a set of typed questions to a model and returns structured answers that can be used directly in R.

JEV is designed for structured decisions rather than conversational chat. The package supports multiple questions in one evaluation, probabilities, confidence, usage, and provider metadata.
