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

We propose Reversible Residual Normalization (RRN), a novel framework that performs spatially-aware invertible transformations to address distribution shift in both spatial and temporal dimensions.

C2weakest assumption

That integrating graph convolutional operations inside invertible residual blocks will produce adaptive normalization that respects the underlying graph structure without introducing irreversible information loss or unstable gradients.

C3one line summary

Reversible Residual Normalization (RRN) introduces spatially-aware invertible residual blocks that combine center normalization with spectral-constrained graph convolutions to mitigate spatio-temporal distribution shifts in graph forecasting.
