pegfail op• Data kinds: table × signal × signal × signal × signal × signal → table
• Call: import fullseye as fs; fs.ledger.wrist_load_from_deflection(kp, q_slide, q_hinge, q_hinge_rest, tip_xyz, axis, lg: 'float | None' = None, peg_mass: 'float' = 0.04, com_from_tip: 'float | None' = None, gravity: 'float' = 9.81) -> 'dict' (to call the implementation directly, import pegfail; pegfail.wrist_load_from_deflection(kp, q_slide, q_hinge, q_hinge_rest, tip_xyz, axis, lg: 'float | None' = None, peg_mass: 'float' = 0.04, com_from_tip: 'float | None' = None, gravity: 'float' = 9.81) -> 'dict'; from the registry, opsdrive.get("wrist_load_from_deflection"))

手首ばねのたわみから、支持(+ 重力)がペグに加える荷重を先端まわりで(numpy だけ): F⃗ = −k_t q_slide − m g ẑ、
M⃗_tip = −k_r (q_hinge − rest) + (p_hinge − p_tip) × F⃗_spring + (p_com − p_tip) × F⃗_g。
`q_slide = (wx, wy, wz) [m] (搬送台に対する手首の並進、搬送台は回らないので世界軸)、q_hinge` = (wrx, wry, wrz) [rad]、
`q_hinge_rest = ばねの静止角(把持の傾き)、lg = 先端からヒンジまで(None → ペグ長)、com_from_tip` = 重心の先端からの
距離(None → 既定のペグ 0.03 kg @ L/2 + 頭 0.01 kg @ L + 3 mm の重心)。ヒンジ 3 軸のトルクはヒンジの軸が世界軸に揃う
小角(手首の回りは 5° 以下)の近似で世界ベクトルとして足す。返り: `F(3,)、M_tip(3,)、F_spring、M_hinge`。
Raises `ValueError`: 形が違う、軸がゼロ。
