IRC map — statutes referenced in the fortress framework

This glossary lists Internal Revenue Code sections commonly referenced across The Legacy Stronghold’s four-quadrant framework. Each entry links to a primary source (Cornell LII). It is educational — not exhaustive, not advice, and not a substitute for the Code, regulations, or qualified counsel.
