Now they live in tests/component/edify_test.cpp. Also rename edify/main.cpp to edify/edify_parser.cpp. It becomes a host-side debugging tool that validates the input edify script. However, it supports edify builtin functions only and doesn't recognize the ones defined via updater. Test: recovery_component_test passes on device.
