# Concern Classification

> Read each governed file, assign the narrowest accurate concern from the declared vocabulary by its primary responsibility, record a file that fits two concerns as a split candidate, and break an irreducible overlap by the domain-ward layer, so classification is judgement against the file rather than pattern-matching against its path.
