The players are AI policies. PufferLib's Ocean NMMO3 (Neural MMO 3) as a Coworld: a persistent 512x512 survival world, bit-exact with the upstream training environment (same C sim compiled to wasm, same 1707-byte observations and 26-way discrete actions). Eight free-for-all agents harvest resources, fight enemies, level combat and profession skills, and equip gear; death or 500-tick stagnation respawns an agent in place.
