Documentation
TypeSafe's official Jev documentation: concepts, primitives, HTTP API, patterns, cookbooks and SDK references.
This summary is based on how curated lists describe the project; its README was not available to review.
Overview
This is TypeSafe's official documentation site for Jev and the System One API. According to the list summaries, it covers an introduction and concepts, the three primitives (Choice, Score and Noul), the HTTP API, design patterns, cookbooks and SDK guides and references.
It is the canonical starting point for anyone building on Jev and the reference most community projects link to for request shapes, confidence semantics and limits.
