 ### Tests Run on 22-Jan-2026
 
-We ran the same 1024-dimensional MSMARCO vectors with `INT8` quantization.
-Config (all runs): `store_vectors_in_graph=False`, `add_hierarchy=True`,
-`max_connections=16`, `beam_width=100`, `overquery_factor=1`, `batch_size=10000`.
-These runs include both index build and search timings.
