traffic op• Data kinds: none → signal (an op determined by its arguments alone — it takes no image or data input)
• Call: import fullseye as fs; fs.ledger.lateral_wobble(n: 'int', dt: 'float', *, theta: 'float', sigma: 'float', seed: 'Optional[int]', x0: 'Optional[float]' = None) -> 'np.ndarray' (to call the implementation directly, import drivetraffic; drivetraffic.lateral_wobble(n: 'int', dt: 'float', *, theta: 'float', sigma: 'float', seed: 'Optional[int]', x0: 'Optional[float]' = None) -> 'np.ndarray'; from the registry, opsdrive.get("lateral_wobble"))
Exact discretization of the Ornstein–Uhlenbeck process dX = −θ X dt + σ dW (a sequence of length n, step dt).

x_{k+1} = x_k e^{−θ dt} + σ sqrt((1 − e^{−2θ dt}) / (2θ)) ξ_k, ξ_k ~ N(0, 1) 独立
遷移分布が厳密なので dt に依らず定常分散 σ²/(2θ)、自己相関 corr(x_k, x_{k+j}) = e^{−θ j dt}(門は長い系列の標本で、許容幅は AR(1) の標本誤差から決める)。x0 = None なら定常分布 N(0, σ²/(2θ)) から引く(最初から定常)。seed は np.random.default_rng(seed)(None も可だが非決定的)。
Raises ValueError: n < 1、dt ≤ 0、θ ≤ 0、σ < 0。
