-ts-remove-unused's behavior heavily depends on your `tsconfig.json`. TypeScript's compiler internally holds the list of project files by parsing relevant rules such as `include` and `exclude`. ts-remove-unused scans through this list and searches for references to determine if an export/file is "unused". You may need to maintain/update your `tsconfig` (or you can create another one for `--project`) so that the set of covered files are right.
