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

stochastic baseline fluctuations arising from finite-memory readout dynamics constitute an intrinsic source of the count-rate-dependent timing jitter in SNSPD systems

C2weakest assumption

The recovery response shape is deterministic and memory is strictly finite; any unmodeled nonlinear or history-dependent detector dynamics would invalidate the quantitative mapping from photon statistics to baseline variance.

C3one line summary

Stochastic baseline fluctuations from finite-memory readout dynamics form an intrinsic source of count-rate-dependent timing jitter in SNSPDs, with a framework that predicts nonmonotonic scaling under pulsed excitation.
