A Gomoku harness narrows 225 moves to about 40 candidates before Jev chooses.

VacekvVita describes a Gomoku harness that detects wins, blocks, forks and broken fours locally, ranks candidate moves into tactical tiers, and gives Jev a board threat summary. Short continuations and the previous move pair help its constrained choice API select a move. The post demonstrates an approach for game-agent builders; it does not report a win rate.
