polish op• Data kinds: scalar → any
• Call: import fullseye as fs; fs.ledger.polish_scene_mjcf(radius: 'float' = 0.008, k_z: 'float' = 500.0, k_xy: 'float' = 20000.0, mass: 'float' = 0.2, friction: 'float' = 0.3, thickness: 'float' = 0.004, timestep: 'float' = 0.0005) -> 'str' (to call the implementation directly, import polish; polish.polish_scene_mjcf(radius: 'float' = 0.008, k_z: 'float' = 500.0, k_xy: 'float' = 20000.0, mass: 'float' = 0.2, friction: 'float' = 0.3, thickness: 'float' = 0.004, timestep: 'float' = 0.0005) -> 'str'; from the registry, opsdrive.get("polish_scene_mjcf"))

平らな板(z = 0 の平面)の上で、円柱の工具(半径 `radius、厚さ thickness、質量 mass`)を x・y・z の 3 本の直動の
関節で動かす MJCF。z は位置サーボ(ゲイン `k_z [N/m] = 手首の押し付けのばね)、x・y は硬いサーボ k_xy`。重力あり。
ばねの閉形式: 工具の底が板に載っている時の法線力 N = m g + k_z (q_surface − q_cmd)(q_surface = 底が z = 0 に来る関節値)。
接触は硬めに(solref の時定数 = 4 × timestep、solimp 0.99)して、めり込みを ばねの縮みより十分小さくする(既定の柔らかい接触では
質量 0.05 kg・5 N で 0.7 mm めり込み、手首のばねと直列になって力が 6 % 小さく出た —— 実測)。摩擦の錐は角錐(pyramidal)。
楕円の錐 + impratio = 10 では、硬い手首(20 kN/m)で 0.1〜0.36 mm めり込んで力が 17 % 小さく出た(摩擦 0 でも同じ、実測)。
Raises ValueError: 数の検査。
