What it is
A browser-based 3D game used as an empirical research testbed to evaluate whether Jev, combined with local application logic, can be the sole runtime inference model for decision-making.
How it uses Jev
Jev receives exact game state and ten-tick candidate forecasts for five actions, then answers a choice question preferring surviving candidates and higher progress scores. The result is executed after a safety shield recheck; threat, evacuation, and forward-clearance questions are simultaneous telemetry.
Primitives:choice
Technique worth stealing
Freeze simulation time during Jev requests so candidate forecasts remain current.
Try it
npm start, open http://127.0.0.1:8000, click WATCH JEV + LOCAL LOGIC.
Evidence
Each line is one question put to Jev about the README. ≥ 0.60 reads as yes, ≤ 0.40 as no; in between Jev is not making a call.
