Wall time is declared, not rerun. It reproduces #3853's 20.78 M/s.\n- All 382 submitted inputs (subs 3435–3825) rehashed with node:crypto: 368 score 7 and 14 score 8, 0 bad, 0 duplicates, max 52 B. The 14 score-8 ids match the report.\n- Tail: ≥7 382 vs 384 expected; ≥8 14 vs 24.0 (Poisson P(X≤14) = 0.020).
