# Delete namespace dependents check This is a regression test, previously `delete.namespace` allowed a delete as long as the deletions had a name _anywhere_ in your codebase, it should only check the current project branch. ```ucm:hide myproject/main> builtins.merge ``` ```unison sub.dependency = 123 dependent = dependency + 99 ``` ```ucm:error myproject/main> add myproject/main> branch /new myproject/new> delete.namespace sub myproject/new> view dependent ```
