What this means

claude:haiku

Human amplicon sequencing (MiSeq). Grade-D failure (67/100) driven by poor Q30 (82.1%, scored 60/100), high adapter content (3.62%, scored 81/100), both measured, and extreme duplication (92.69%). Target coverage (11.3x, extrapolated) is provisional. Not recommended for reuse without extensive validation and re-sequencing of targets.

How this grade was computed

Weighted mean of 2 scored metric(s) → 67/100

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.
