Sanjeeda Sultana, Surajit Chattopadhyay

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 reconstructed THDE model in f(Q,C) gravity exhibits strong consistency with observational data from CC+Pantheon+ + DESI DR2, passes through the LambdaCDM fixed point in statefinder diagnostics, and satisfies the four energy conditions.

C2weakest assumption

The reconstruction procedure assumes a specific functional form for f(Q,C) and a direct mapping of the Tsallis holographic density onto the modified gravity equations without additional fundamental constraints from quantum gravity or consistency requirements.

C3one line summary

Reconstructs THDE in f(Q,C) gravity, fits parameters via MCMC to CC+Pantheon+DESI DR2 data, and verifies consistency with LambdaCDM through statefinder diagnostics and energy conditions.
