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

The long-wavelength limit provides a direct response test of the spin stiffness implied by thermal local-spin-density-approximation (LSDA) parametrizations, showing low-temperature consistency while exposing a resolved warm-dense residual in current LSDA parametrizations.

C2weakest assumption

The variational diagrammatic Monte Carlo simulations converge sufficiently to capture the true spin XC kernel without uncontrolled systematic biases in the warm-dense regime at metallic densities.

C3one line summary

Computes the finite-temperature static spin XC kernel K_xc(q;T) for the unpolarized uniform electron gas across quantum-degenerate to classical regimes.
