QUALITY_CHECK
=============

Python object: ``phenotypic.schema._quality_check.QUALITY_CHECK``

Generic QC output columns emitted by every QualityCheck subclass.

The category convention used elsewhere in the codebase would produce
column names ``QC_Flag``, ``QC_Metric``, ``QC_Status`` — but the
actual emitted columns include each subclass's ``name`` between the
category and the label (``QC_Count_Flag``, ``QC_SE_Flag``). This
enum overrides ``append_rst_to_doc`` to substitute the subclass's
``name`` into the RST column header, so each concrete subclass's
docstring documents its real emitted columns.

     - :bdg-ref-secondary:`Quality <measurement-classification>`
   * - ``QC_Metric``
     - Headline metric in the check's own units; the bad direction is set by the check's _HIGHER_IS_BAD flag. Drives Status.
     - :bdg-ref-secondary:`Quality <measurement-classification>`
   * - ``QC_Status``
     - Categorical: pass \| warn \| fail.
