# Macro Tests Layout - if/: If normalization cases (assign, print, return, chains/guards) - loopform/: Loop normalization (carrier tail align, two-vars) - collections/: Array/Map macro examples - types/: Type checks (is/as) - strings/: String macros (upper_string) - identity/: Identity macro - test_runner/: Macro test runner behavior (filters, args, return policy) Each file is a thin include to the original sample kept at the root for now. Once stabilized, originals can be removed and bodies moved here.
