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 closed-loop experiments demonstrate decentralized EMFF with AMFF where the maximum steady-state formation error is less than ±0.01 m and the settling time is less than 30 s.

C2weakest assumption

That the time-averaged interaction force is nonzero if and only if alternating magnetic moments share the same frequency, and that this holds without significant cross-frequency interference or external disturbances in the experimental setup.

C3one line summary

First closed-loop experimental demonstration of 3-satellite electromagnetic formation flying via frequency-multiplexed alternating magnetic forces, with steady-state errors below 0.01 m.
