Separate original findings from commentary

Inputs: [CLAIM], [SOURCE LIST], [PRIMARY DOCUMENTS]. Map each statement to original data or primary document, secondary interpretation and repetition. Note where a primary source cannot be accessed. Output: A source lineage table and revised claim wording. Check: Repeated summaries are not counted as independent confirmation. If essential information is missing, identify it rather than filling the gap with a guess. Identify when multiple secondary accounts repeat one original source rather than independently corroborating it.
