Evidence and scope
Documented records the linked documentation or source. JevHunt has not independently run or benchmarked this project.
The comparison is fair by construction. Jev is called via `typesafe-sdk`, and Claude is called via [`system-one-adapter`], a drop-in replacement for the same `system_one()` API backed by Claude's structured outputs. Every model gets identical questions and is scored by identical code.
