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

The proposed topology-preserving augmentation achieves near-perfect Cyclic Adjacency Preservation (CAP) across common geometric transformations and improves annotation consistency in polygon-based segmentation.

C2weakest assumption

That repairing adjacency relations in index space while preserving vertex order is sufficient to maintain semantic validity of the ring-type polygon under all relevant transformations without introducing new artifacts.

C3one line summary

A lightweight augmentation technique repairs adjacency relations in index space for ring-type polygons to preserve topology under geometric transforms while keeping original vertex order.
