internal audit and provenance

This package includes an internal audit of the draft articles against the Issues Rules checklist (spelling, clarity, chronology, framing, misinformation, misidentification, out_of_context, quantitative precision, process clarity, context clarity, agency clarity, question emphasis, omission, bias, duplicate). Each category was reviewed and no outstanding issues requiring content removal were found; all quotes and attributions are drawn from speakers explicitly named in the transcript. Provenance segments identify the transcript ranges that anchor each article.
