✓ Portable graph bundle live · download bundle · merged state

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

Numerical results show that the proposed MA array outperforms single fluid antenna and fixed array systems, with reduced inter-element spacing providing further performance gains.

C2weakest assumption

The analysis assumes a full, spatially coherent correlation model together with continuous positioning of the array along a line.

C3one line summary

Derives SNR CDF tail approximations and closed-form LCR for linear movable antenna arrays with full spatial correlation, showing gains over fixed and fluid antenna systems.
