tactorque op• Data kinds: matrix × matrix × scalar × scalar × table × scalar → table
• Call: import fullseye as fs; fs.ledger.torsion_stick_field(X, Y, a: 'float', Mz: 'float', kern: 'dict', G: 'float') -> 'dict' (to call the implementation directly, import tactorque; tactorque.torsion_stick_field(X, Y, a: 'float', Mz: 'float', kern: 'dict', G: 'float') -> 'dict'; from the registry, opsdrive.get("torsion_stick_field"))

無滑りねじり(Reissner–Sagoci、Johnson 1985 §3.9 相当、式番号は未確認 → 畳み込みで数値検証)の表面変位場: トラクション
q_θ = 3M_z r/(4πa³√(a²−r²)) を :func:tacslip.cerruti_kernel の核で畳んだ `ux・uy [m] と、閉形式 beta` = 3M_z/(16Ga³)、
円内の剛体回転 `ux_cf = −βy・uy_cf = βx(r < a)、トラクション qx・qy`。畳み込みが円内で一様な u_θ/r = β を返すことで β の式を
独立実装で検証する(−0.5 %、一様性 0.14 %、実測)。これは無滑りの場: 平頭押し込み子なら全滑りの 8/(3π) 倍まで厳密だが、Hertz 接触では
縁から必ず滑る —— Hertz 接触の部分滑りの場は :func:cuttouch.torsion_partial_slip の `field=True`(モジュール docstring 参照)。
Raises ValueError: G ≤ 0、a ≤ 0、X と Y の形が違う、核の格子が合わない。
