MSS chaos bound saturation: λ_L/(2πT) = 1 at the SYK / black-hole point

Pinning statement of the Maldacena-Shenker-Stanford 2016 chaos bound at the saturation / reference point. In natural units ℏ = k_B = 1, the bound reads λ_L ≤ 2π·T. The saturation ratio λ_L^sat / (2π·T) = 1 — the universal benchmark…
