packages/@react-native-windows/tester/src/js/utils/RNTesterList.windows.js:494
- This registers an RNTester example whose
NativeCxxModuleExampleCxxprovider does not exist on Windows (repository-wide native-code search finds only the nullable JS spec). The example still renders all controls, but every optional module call returnsundefined, so it is nonfunctional. Omit this entry until the native implementation is registered.

packages/@office-iss/react-native-win32-tester/src/js/utils/RNTesterList.win32.js:387
- This registers an RNTester example whose
NativeCxxModuleExampleCxxprovider does not exist in the Win32 native code (only the nullable JS spec is present). Its controls therefore execute against a null module and cannot produce results. Omit this entry until the native implementation is registered.

- This disables C4715 for every translation unit in
Microsoft.ReactNative, allowing future non-void functions with missing returns (undefined behavior) to compile despiteTreatWarningAsError.vnext/Shared/Shared.vcxitemsscopes this warning to individual upstream files (for example lines 480 and 484–488); identify the new offender and suppress it only on thatClCompileitem.
vnext/ReactCommon/TEMP_UntilReactCommonUpdate/react/nativemodule/defaults/DefaultTurboModules.cpp:8 - This file is copied over
node_modules/react-native/ReactCommonbyReactCommon.vcxproj, but unlike every otherTEMP_UntilReactCommonUpdatepatch it has no entry invnext/overrides.json(see the existing entries at lines 59–226). The override upgrader therefore cannot validate or rebase this divergent copy on the next RN integration. Register it as a patch againstpackages/react-native/ReactCommon/react/nativemodule/defaults/DefaultTurboModules.cppwith the target base hash.
