✓ Portable graph bundle live · download bundle · merged state

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

explicitly modeling temporal prototype evolution is a practical and interpretable strategy for robust continual remote sensing segmentation

C2weakest assumption

That enforcing low-curvature motion and inter-class separation on learned prototype trajectories is sufficient to control representation drift and catastrophic forgetting without additional mechanisms such as replay buffers or architectural expansion.

C3one line summary

ProtoFlow stabilizes class prototypes via low-curvature temporal flow to mitigate forgetting in class- and domain-incremental remote sensing segmentation.
