Uncertainty-aware control flow for Effect: Jev's Choice, Noul and Score answers become typed patterns with an explicit Uncertain branch, plus routable procedures, recording, replay, caching and call budgets.
Craft Type-Safe Uncertainty-aware semantic pattern matching, control flow, and smart procedures for Effect DecisionModel and Jev
How it uses Jev
Type-safe patterns, policies and routable procedures over Effect's Decision and DecisionModel — where maybe is a branch you handle, not a rounding error. Provider-neutral: runs on TypeSafe's Jev, or any other DecisionModel .
