We revisit Brownian Sachdev-Ye-Kitaev model and argue that it has emergent energy conservation overlooked in the literature before. We solve this model in the double-scaled regime and demonstrate hyperfast scrambling, exponential decay of correlation functions, bounded spectrum and unexpected factorization of higher-point functions. We comment on how these results are related to de Sitter holography.

Out-of-time-ordered Correlators in de Sitter Revisited
The de Sitter OTOC grows at the maximal Lyapunov rate 2π/β at tree level and at twice that rate in a massive-graviton-regulated double-scaling limit, with the growth traced to large diffeomorphisms in the graviton propagator.
