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

With these strategies, our proposed method successfully ranks the 1st place in the challenge.

C2weakest assumption

That the performance gain is primarily attributable to the three listed changes rather than differences in training schedule, optimizer settings, or undisclosed data filtering that were not ablated.

C3one line summary

X-Restormer++ wins the UG2+ all-weather image restoration challenge by combining adaptive scaling, a gradient-guided edge-aware loss, and expanded training data on top of the X-Restormer baseline.
