Classification Evaluation & Provenance Integrity
Evaluation integrity notice: Classification evaluation metrics were re-keyed during Phase 4 audit against ground-truth labels independently from rule outputs, resolving potential circularity in extraction diagnostics.
Target resolution measures exact statutory section/subsection matching against the human gold set. Classification performance evaluates change type assignment over matched amendments. Independent human inter-annotator agreement is tracked separately as pending research validation.
