so the source-tree fallback is selected only when the requested resource exists;
otherwise resolve it through importlib_resources.files(_PACKAGE_NAME). Add a
regression case covering a partial source tree where the directory exists but a

Thanks for catching and fixing this — the source-tree assumption came from the contract tests added in #4069. Using packaged resources is the right approach here. I missed the isolated package-test setup. |
