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

when acoustic wave flux drops below ∼5×10^6 erg cm^{-2} s^{-1}, mass-dependent thermal velocities dominate the fractionation process, producing counterintuitive patterns where Fe exceeds Ca in FIP bias, while high-FIP Ar shows fractionation. We demonstrate that any source of chromospheric turbulence will act to suppress fractionation.

C2weakest assumption

The assumption that the specific nanoflare-like impulsive heating events in the HYDRAD simulations and the chosen acoustic flux values accurately represent real chromospheric dynamics, and that the ponderomotive force calculations in FIPpy capture all relevant fractionation physics without additional unmodeled effects.

C3one line summary

Chromospheric dynamics and turbulence regulate the solar FIP effect, with acoustic flux below ~5e6 erg cm^-2 s^-1 causing mass-dependent fractionation patterns and turbulence suppressing bias.
