Notes

  • The PDF chapter order is not a 1:1 mirror of the web module order.
  • Chapter 12 currently exists only in the PDF/exercise tracks, not as a web module.
  • The validated current PDF/product baseline is 48 exercises / 12 chapters / 4 appendices.
  • The wiki is a status/reference surface, not the source of truth for build or release procedures.
