+## Philosophy
+
+**Each unit of engineering work should make subsequent units easier—not harder.**
+
+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
+- Keep quality high so future changes are easy
+- Prefer duplication over premature abstraction
+
