 ## Unreleased

+### Diagnose unknown declared return types
+

+- Added focused negative-fixture coverage and release-validator coverage for the invalid declaration.

 ### Diagnose empty typed returns

 - `claro typecheck` now reports a beginner-facing error when a function or method declares `RETURNS TYPE` but uses `RETURN` without a value.
