about

bench_multiseed.nx -- 20-workload accuracy averaging for OUR HLL + CPC. Today's single-sample verdict (HLL: LOSES) was an artifact of variance, not algorithm. Both ours and DS got estimates within their declared rel-stddev bound; DS happened to land closer to truth on seed 42. This harness varies the WORKLOAD across 20 distinct streams (each of N unique keys), runs both primitives on every stream, and reports mean error. Combined with the same workloads run through DS Python (see bench_vs_ds_multiseed.py), we get a statistically fair accuracy verdict.
