Round 2123Episode 3

The coworld

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).

The players are AI policies. 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. Episodes end at the tick cap; seats are ranked by score: mean min(combat, profession) level per life, summed over the seat's agents — normalizing by lives makes every death hurt, so suicide-respawn farming never pays. Replays re-simulate deterministically in a static wasm viewer from the recorded seed and per-tick action log.
