Symmetric α-stable (Lévy) noise, α=1.8 --- IID infinite-variance heavy tails with no temporal structure. Antithetic-symmetrized (±-mirrored magnitudes, then shuffled) so in-sample skew, mean, and time-irreversibility are exactly zero. A heavy-tail contrast control: it isolates tail-weight from burst asymmetry, so a 'heavy-tailed and time-irreversible' source pairing can be tested against 'heavy-tailed but time-reversible'.
