ball op• Data kinds: table × table → table
• Call: import fullseye as fs; fs.ledger.bounce(v, omega, normal, bp: 'dict', ip: 'dict') -> 'dict' (to call the implementation directly, import ballistics; ballistics.bounce(v, omega, normal, bp: 'dict', ip: 'dict') -> 'dict'; from the registry, opsdrive.get("bounce"))

剛体球が平面に当たる瞬間の速度・角速度の更新(クーロン摩擦、Cross 2002 / Garwin 1969 の 2 領域)。
接触点の滑り速度 s = v_t − r(ω × n)_t。必要な接線力積が μJ_n 以下なら滑りが止まって転がりに移る(grip)、
超えるなら滑ったまま(slip、接線力積 = μJ_n)。法線は v_n' = −e v_n(e は定数か |v_n| の関数)。返り値
`{"v", "omega", "regime" ("grip"|"slip"|"none"), "J_n", "J_t", "slip_speed", "e"}`。
`v·n ≥ 0(離れていく)なら何もしない(regime "none")。定理: 接触点まわりの角運動量は保存(:func:contact_angular_momentum`)。
