## Summary - Pin `grpcio-tools==1.81.1` for Python 3.14 in `sdks/python/pyproject.toml` build-system requires so Windows installs a binary wheel instead of building from source. - Keeps `1.71.0` for Python 3.13; avoids `1.82.1` because it requires `protobuf>=7`, which conflicts with Beam's current `protobuf<7` bound. ## Root cause Windows Python 3.14 CI (unit tests, wordcount, and cp314 wheel builds) failed installing `grpcio-tools==1.71.0` from source with MSVC `D8016` (`/std:c++17` and `/std:c11` incompatible). `1.71.0` has no Windows cp314 wheels; `1.81.1` does (and matches container pins). ## Test plan - [ ] Confirm Windows Python 3.14 unit tests / wordcount install `grpcio-tools` from wheel (no source build / D8016) - [ ] Confirm `Build python cp314- wheels on auto for windows-latest` succeeds - [ ] Spot-check Python 3.13 / <=3.12 builds still use their existing pins -- This is an automated message from the Apache Git Service.
