Latency Table Compares Flat Dense, Hierarchical Baseline, and Adaptive (Heuristic) Per Dataset

The paper's headline latency table reports mean latency per query in milliseconds for exactly three retrieval systems under the CPU-only protocol: Flat dense, Hierarchical baseline, and Adaptive (heuristic). Rows are indexed by dataset, so each dataset gets one timing per system. The three-column choice mirrors the headline strict-parity retrieval table (flat dense vs. fixed-depth hierarchical baseline vs. adaptive depth gating), so compute cost is reported for the same systems whose retrieval quality is compared, not for an unrelated set of comparators.
