PROMPT FPS

Structured state, not pixels. A bridge in the vendored Chocolate Doom fork exposes health, armor, ammo, damage, coordinates, kills, line-of-sight monsters and visible pickups to JavaScript, and the browser converts that into the same bounded tactical schema for both players. Jev never touches engine internals: a local controller executes each chosen macro as movement, turning, firing, weapon or use inputs.

A failed or low-confidence call is visibly marked FALLBACK and never silently becomes simulated Jev. Offline mode permanently displays OFFLINE SIMULATED POLICY - NOT JEV. So a comparison can always be traced back to whether a real decision or a deterministic policy produced it.

It is transmitted once to the local Node/Vite server, kept only in process memory, never logged or persisted, and removed on disconnect or page close. You can instead start the server with TYPESAFE_API_KEY in its environment. The README is explicit that a VITE_-prefixed variable must never be used, since that would ship the key to the browser.

Only Freedoom 0.13.0 ships. A legally owned commercial IWAD may be used during local development, but no commercial WAD, texture, sprite, map, logo, music or sound is included. The vendored Chocolate Doom fork is GPL-2.0-or-later with its notices under licenses/, while the project itself ships no license file, so reuse terms for the surrounding code are unclear.

Run `npm install` then `npm run dev`, open http://127.0.0.1:5173/compare, click Connect Jev and paste a TypeSafe API key, then start both players. You can also start the server with TYPESAFE_API_KEY in its environment; never use a VITE_ key variable.

Chocolate Doom is GPL-2.0-or-later and its fork source is included; Freedoom content is BSD-licensed and credited in licenses/. No commercial Doom WAD, texture, sprite, map, logo, music or sound is included, though a legally owned commercial IWAD may be used during local development.

Yes. There is an explicitly labeled deterministic offline policy, and offline mode permanently displays 'OFFLINE SIMULATED POLICY - NOT JEV' on screen. The repo also ships `npm test`, `npm run build`, `npm run smoke` to boot two WASM engines, and `npm run video` for capture.
