Annotator Input Parity Check
Problem
A model built to replicate human labels is fed a different evidence base than the one the annotators used. The mismatch masquerades as a modeling or construct problem: recall collapses on the label subset whose evidence lives only in the annotators' source, audits produce increasingly sophisticated theory ("invisible" positives, construct splits, per-domain reliability gates), and successive model generations inherit the wrong input because each review critiques the lineage from inside the frozen input assumption.
