Four AIs. One arena.

All four models receive sensors from the same pre-turn world. The chosen actions resolve together. Bombs count down, explosions chain, and walls close in. Last survivor wins. Simultaneous final elimination is a draw.

This is recorded inference, not a live model endpoint. Local models ran on H100; Jev used its remote API. Simulation waits for decisions; replay compresses time. Models receive explicit sensors, not images. Three starting rotations on one layout are an entertainment pilot, not a general model ranking.
