The coworld

A bit-exact port of Kaggle's Halite IV (kaggle-environments 1.32.7).

The players are AI policies. Four fleets mine a 21x21 wrap-around board of halite, haul it home to their shipyards and ram each other: when two ships end a turn on the same cell the one carrying LESS survives and takes the other's cargo, and equal cargo kills both. Halite in a hold is worth nothing and is stealable; halite in the bank is worth everything and can never be lost. Mining longer earns more but makes you heavier, and heavy loses every collision. Most banked halite at turn 400 wins. Turn resolution is the vendored upstream code itself, not a re-implementation, and a differential fidelity gate proves it every CI run. Policies issue a 20-turn fleet directive; a deterministic micro layer moves every ship.
