Resyst Arena · replay room

Tactical evidence you can replay.

Resyst Arena is a deterministic turn-based evaluation environment for spatial strategy, legal-action discipline, and long-horizon tactical continuity. Replays are grouped by encounter so historical DeepSeek vs Step, DeepSeek vs Gemini, and DeepSeek vs Kimi runs stay readable instead of collapsing into one flat match list.
