What this means

claude:haiku

Good-quality amplicon metagenomics with adequate Q30 (84.9%, weight-1 metric, scored 74/100) and minimal adapter contamination (1.75%), grading B. High duplication (81.1%) is amplicon-expected. Solid for microbial profiling, though Q30 is borderline for rare-taxa taxonomy; reuse conditional on lenient thresholds.

How this grade was computed

Weighted mean of 2 scored metric(s) → 81/100

The B grade is a transparent weighted average. Each metric below scored from 0–100% against the published amplicon thresholds, weighted by its importance; nothing is hidden or subjective.
