# Developer and operator tools These files are not required by the running RustProxy proxy process. - `checks/` - compiler-independent source/release/documentation contracts and UI checks. - `dev/` - local mock services and diagnostic traffic/compression helpers. - `audit/` - explicit operator audit/probe tools. - `legacy/` - retained compatibility/release-test helpers; not the supported production workflow. Production packages do not need this tree unless a packaging/test workflow intentionally ships it.
