Slot: Quality Flag Column (quality_flag_column)

Name of any per-value QA flag column. CF ancillary_variables analogue; the flag vocabulary lives in the Uncertainty microschema.

Tier: optional

Why this slot matters

Without knowing where the per-value QA flags live, consumers cannot filter or down-weight values the producer already marked as suspect, so known-bad measurements flow silently into analyses.

In plain terms

A quality flag column is like a traffic light next to each number — good, suspect, or bad — recorded by the data producer. This slot names that column; what the flag codes mean is described in the Uncertainty microschema.
