Something about the new python build is odd. From the build logs:

inflating: python-sdk/lib/logging/handlers.py  

However if I look at the current main and the sdk there, that file sits in

python-sdk/lib/python3.14/logging/handlers.py

That's also why the tests fail, see https://github.com/influxdata/datafusion-udf-wasm/blob/main/CONTRIBUTING.md#python-fails-to-start--no-module-named-encodings

Looking at https://github.com/influxdata/cpython-wasi-build/commits/main/ I think we've messed up the branching a bit here: you've forked that project from

https://github.com/brettcannon/cpython-wasi-build/commits/main/

which is the dev branch for Python 3.15, but you should have forked it from

https://github.com/brettcannon/cpython-wasi-build/commits/release/3.14

So my suggestion is to:

1. create a clean fork from the 3.14 branch and also name our branch release/3.14 to avoid that confusion
2. delete all releases
3. trigger a new release build
4. try again here
