Research evidence

router.mjs calls experimental_evaluate with typesafe-ai/jev, a harness Choice, complexity Score and planning boolean. Policy can override the raw choice before an optional launch.
HN item 49747155 points to this local prototype. It is distinct from the baseline gargpratyush/jev-router.
The routeConfidence variable holds the winning option's probability, not a separate native confidence field. No harness was launched and no model call was made.
