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

current noise is governed by two competing factors: the average occupancy distribution and particle-number fluctuations. With energy fully relaxed, shot noise is strongly suppressed, reflecting the stacking of electrons into lower energy states due to dissipation. This process quenches the partition noise from partially occupied levels, and finally isolates the residual noise protected by strong U(1) symmetry.

C2weakest assumption

The mapping of the dissipative chiral transport system onto a quantum circuit fully captures the open-system dynamics and allows the noise to be decomposed exactly into occupancy and fluctuation contributions without additional uncontrolled approximations.

C3one line summary

Dissipation in chiral transport quenches partition noise by relaxing electrons to lower states, leaving only U(1)-protected residual noise, while selective heating reveals competing contributions and an inversion scheme reconstructs the occupancy distribution from noise cumulants.
