A nested altChunk DOCX adds its records past its 256-entry list to the outer
total. file.strictReport's params doc lists source_part, the snake_case codes
and the totals. The human line says "300 characters cannot be drawn (first 256
listed)" when a list is cut. README gains the picture stderr line and the
possible source_part values.
