tacdome op• Data kinds: signal × scalar → signal
• Call: import fullseye as fs; fs.ledger.largedef_radius_ratio(d, p: 'float', method: 'str' = 'quadrature') (to call the implementation directly, import tacdome; tacdome.largedef_radius_ratio(d, p: 'float', method: 'str' = 'quadrature'); from the registry, opsdrive.get("largedef_radius_ratio"))
Contact-radius ratio a/a_L under large deformation (Eq. 4) = (1/p)·B_d(1/p, 3/2)·d^{−1/p}/√(1 − d) = ∫₀¹ √((1 − d·uᵖ)/(1 − d)) du.

method="quadrature"(既定): 右の積分を 1 に寄せた複合 Gauss–Legendre で。"beta": 原文の形どおり不完全ベータの連分数で(別の経路、照合用)。p = ∞(平頭)は非圧縮の半径の伸び 1/√(1 − d)。d → 0 で 1 + d·p/(2(p+1))。p = 1・2 の閉形式は (2/(3d))(1 − (1 − d)^{3/2})/√(1 − d) と [√(1−d)/2 + atan2(√d, √(1−d))/(2√d)]/√(1 − d)。Raises ValueError: d が [0, 1) の外、p が範囲外、method の綴り違い。
