Checks

  • Use footnote references when footnotes change legal, financial, or scientific meaning.
  • Store footnote references with extracted answers that cite affected text.
  • Review symbol-heavy documents manually the first time you add a new document family.
  • Keep standard citations too; footnote links complement citations rather than replacing them.
