+# Standards
+
+- Keep the Rust code modular and readable.
+- Treat planning as the only user-input phase.
+- Treat execution as autonomous except for pause, resume, stop, and goal update.
+- Keep controller-owned machine state in TOON files.
+- Leave the codebase in a maintainable state after each completed step.
