QUALITY_TUKEY
=============

Python object: ``phenotypic.schema._quality_tukey.QUALITY_TUKEY``

Measurement info for the replicate-agreement Tukey-fence QC check.

Documents the per-check extra columns behind the Tukey-fence agreement
check, which flags colonies whose measurement falls outside Q1 - k*IQR or
Q3 + k*IQR relative to their replicates or detection runs. Members beyond
the fences are robust outliers that frequently reflect contamination, edge
artifacts, or segmentation errors rather than real biology, so these
columns drive curation decisions downstream of the QC pipeline.
