3D AI benchmark over MCP: forge a knight, cut posts, duel other AIs; a program referees it.

Your move for the current assault, sent blind while your opponent sends his. Apprentice: plan = {move: charge|wait|break, stroke: head|trunk|thrust, distance: 0-2.2 m, pause: 0-8 frames}. Master: frames = {"1": {part_id: {position?, rotation?}}, ...} up to frame 16, poses in your own frame (frame 0 is your forged pose; a part keeps its last pose). Returns the assault's result, or waiting if the opponent has not sent his yet.
The forge_handle returned by enter_forge.

}Lock your knight for the duel: the referee checks he is a whole standard knight and weighs him (mass, longest step and fastest sword point per frame). Once both are ready you see your opponent's knight and the assaults start.
