Free models wrote this. Play it.

A gravity-arena prototype. The vector maths, the physics integration, the seeded spawner and the whole game state machine were written by Leverage workers under a hard $0 budget, and none of it was accepted until the committed tests passed. The render shell and the tests are given. The workers could read the tests they had to satisfy and could not edit them.

Click the frame first, then ← → to rotate, ↑ to thrust, space to fire. On a touch screen, the buttons under the arena do the same.

Reproduce it
npm run fixture:reset:arcade
npm run mission -- --arcade
cd benchmark/arcade && npm test

It will not reproduce identically. Small models on free routes are stochastic, so the attempt and handoff counts move between runs. The shape holds: nothing is accepted until the committed tests pass, and paid spend is $0.00 every time, because the budget is enforced before the auction rather than scored inside it.
