Hygiene is a measurement, not a promise.

A requirement arrives in words and leaves as criteria. Checks run against the output, not against the intention. Figures are reported as ranges where a single number would overstate what is known.

Jurisdiction split

Separating records by the rules that apply where the person is, not where the file was built.

Honest residue

The portion we could not verify, reported as unverified rather than as clean.

Criteria translation

Finding the nearest countable equivalent when a requirement has no direct expression in the available fields.

The size of the audience is usually the answer to the real question.
