What this means

claude:haiku

SARS-CoV-2 amplicon achieving highest D-grade score (69/100) due to lowest adapter contamination in this cohort (13.91%, measured, scoring 8/100). Despite excellent base quality (Q30=96.7%, mean Q=36.5, measured) and large depth (3.6M reads), residual adapter still constrains reliability for quantitative applications. Marginal for reuse post-trimming.

How this grade was computed

Weighted mean of 2 scored metric(s) → 69/100

The D 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.
