What this means

claude:haiku

Amplicon with marginal quality (C grade, 79/100) due to sub-threshold Q30 (83.8%, scored 69/100) and extreme duplication (91.27%, inherent to PCR amplicon). Low coverage (5.9x, extrapolated) and elevated n-content (0.121%) compound constraints. Reuse acceptable only for high-redundancy applications; quantitative work not recommended.

How this grade was computed

Weighted mean of 2 scored metric(s) → 79/100

The C 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.
