What this means
claude:haiku

Short-read amplicon sequencing on MiSeq targeting freshwater metagenome with high quality (92.8% Q20, 89.2% Q30). This environmental community profiling enables microbial diversity assessment, biogeographic inference, and identification of rare taxa in freshwater ecosystems; compact 617 Mb dataset suits downstream analytics.

How this grade was computed
Weighted mean of 2 scored metric(s) → 97/100

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.
