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

Using the analytical BER, we select the control angle that maximizes throughput while satisfying a target BER reliability constraint.

C2weakest assumption

Trimodal pixel-value histograms motivate an adjacent-only inter-symbol interference (ISI) model in which the decision at segment j depends on adjacent segments.

C3one line summary

Derives a closed-form BER expression for rotating light-trail ISC using an adjacent-only ISI model based on trimodal pixel histograms and applies it to optimize control angle under a target BER constraint.
