 Traditional development accumulates technical debt. Every feature adds complexity. The codebase becomes harder to work with over time.
 
-Compounding engineering inverts this:
-- Document patterns as you discover them
-- Codify learnings so they're reusable
+Compound engineering inverts this. 80% is in planning and review, 20% is in execution:
+- Plan thoroughly before writing code
+- Review to catch issues and capture learnings
+- Codify knowledge so it's reusable
 - Keep quality high so future changes are easy
-- Prefer duplication over premature abstraction
