Indoor referring retrieval favors category names: R@10 rises from 0.626 to 0.911 on ScanRefer, while geometry wins only on paraphrases
Under a fixed prompt budget, matching a query to object category names places the target in context more often than pairwise geometry scoring, lifting R@10 on ScanRefer from 0.626 to 0.911, though geometry overtakes it when the query omits the target category word.
