Four decision-quality tools built on Jev (TypeSafe System One), one shared kernel — Jev answers structured questions; deterministic code keeps the final say. Jev is a decision model that answers typed questions (score / choice / noul) over a state. Each app in this suite takes one real-world "did it actually happen as required?" problem, feeds Jev sanitized evidence, and keeps the thresholds, vetoes, and routing in plain Java.
