Deep data QC

100/100 · A

Standardized, field-standard QC computed by touching the data — every metric states how it was obtained · evidence: measured

What this means

claude:haiku

Amplicon dataset with perfect QC driven by Q30 purity (97.5%, measured) and negligible adapter contamination (0.57%, measured), both essential for accurate taxonomic classification. Target coverage is extrapolated; validation pending measured confirmation.

How this grade was computed

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

The A 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.
