Glossary

This glossary is built from the lessons, not before them. A term only earns a page here after a lesson has made it real — so every entry tells you the lesson it first appeared in, and links back to it.

If you landed here first: don’t read this top to bottom. Start at 0.1 and let each term arrive in context. Come back when you want a quick definition or a reminder of where a concept was introduced.

Term pages are added as each level is authored. Level 0 and Level 1 terms are live; higher-level terms fill in as you climb.
