   Thanks for digging into this! I added this test to exercise the tie-breaking logic. But now I think it wasn't a good idea -- HNSW is known to exhibit very poor performance when vectors are duplicated. And this test takes it to an extreme! It's not really a scenario we support well.
   
   Maybe we could just remove this test. It wasn't critical, and I could always follow-up with a better way to test tie-breaking.
