  "rationale": "Filler in an evidence field converts a question a reviewer would have skipped into one they now have to resolve, and \"N/A\" beside a field they expected content in reads as a refusal rather than an absence. It comes from forms that mark every field required, so the submitter types something to get past validation and inherits a finding.",
