filter_kv_indices_for_cp_rank built rank_page_indices = kv_indices[range_mask] and then ran np.isin(kv_indices, rank_page_indices) — provably identical to range_mask itself (a value is in the filtered subset iff it passes the same range test), at the cost of an extra sort per chunk send under SGLANG_DISAGGREGATION_ALL_CP_RANKS_TRANSFER=1. Apply the range mask directly: 30.5 -> 8.1 us per 1024-page chunk. Differential test pins equivalence against a verbatim copy of the old logic. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
