The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

This separation is not intrinsic to the flow but strongly depends on the finite vertical span of the measurements. As the vertical scan range increases, the apparent crossover between 2D and 3D-dominated regimes shifts systematically.

C2weakest assumption

That varying the vertical scan range isolates the effect of finite measurement windows without introducing confounding changes in the underlying turbulence, such as altered boundary conditions or forcing at different heights.

C3one line summary

The frequency crossover between quasi-2D and 3D regimes in rotating turbulence shifts systematically with vertical measurement span, showing the partition is shaped by finite observation windows rather than being intrinsic to the flow.
