\subsection{Limitations}
 \Ours{} has two main limitations. First, in scenarios with very low or no overlap, the topology repair heuristic may erroneously connect geometrically unrelated structures, introducing local artifacts (see Figure~\ref{fig:fig_com_depth}). Second, our method is mainly  designed for small-scale, static scenes and does not generalize to dynamic scenes or large-scale unbounded scenes. These limitations motivate future research directions.
