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 single parametric model outperformed the best discrete non-parametric case, reducing the total relative force estimation error for the reference signal by nearly 38%.

C2weakest assumption

That a parametric model fitted to only 15 discrete load levels will accurately capture the continuous nonlinear dependence on load amplitude and generalize to arbitrary input waveforms without overfitting or missing unmodeled dynamics.

C3one line summary

A parametric data-driven model built with p-AAA reduces relative force estimation error by nearly 38% versus the best non-parametric model while generalizing across load amplitudes and input waveforms.
