puck op• Data kinds: signal × signal × scalar × scalar → table
• Call: import fullseye as fs; fs.ledger.puck_wall_bounce(v, normal, e: 'float', kt: 'float' = 1.0) -> 'dict' (to call the implementation directly, import puck; puck.puck_wall_bounce(v, normal, e: 'float', kt: 'float' = 1.0) -> 'dict'; from the registry, opsdrive.get("puck_wall_bounce"))
Collision with a wall: normal component vₙ' = −e vₙ, tangential component vₜ' = kₜ vₜ (e = normal coefficient of restitution, kₜ = tangential retention ratio = tangential coefficient of restitution).

回転は持たない(壁の摩擦で入る回転は接線の減りに畳んである。Cross 2022 のディスク衝突は「滑りか把持か」で接線の反発係数を書く —— その 2 領域は入れていない)。返り値 {"v", "vn_in", "vn_out", "vt_in", "vt_out", "energy_ratio"}。法線だけの衝突なら energy_ratio = e²(門)。v·n ≥ 0(離れていく)なら何もしない。
