micropip requires the full PEP 427 wheel filename (name-version-py-abi-plat.whl) — writing the file as bincio.whl caused InvalidWheelFilename. The wheel URL from /api/wheel/version now provides the basename; it flows through fetchWheelBase64 → extractFile → WebView where the file is written with the correct name and _wheel_path is set as a Pyodide global before PY_INSTALL_WHEEL runs.
