NOTICE:  turbovec: built a FLAT (exact) index over 1000000 rows
DETAIL:  Flat is an exact O(n) scan (recall@10 = 1.000). For approximate cell-pruned search, rebuild WITH (lists = N), N ~ sqrt(row count). Flat is often FASTER and more accurate at this scale -- see the Choosing lists section of the README before switching.
