litellm ships its own Rust extension (litellm-rust python-bridge ->
litellm.rust_bridge._native, built via maturin/PyO3). Releases before
1.93.0 publish no cp314 wheel, so on Python 3.14 uv falls back to the
sdist and the build fails:
error: the configured Python interpreter version (3.14) is newer
than PyO3's maximum supported version (3.13)
1.93.0 adds cp314 wheels and a PyO3 that builds on 3.14. Raising the
floor fixes the failure at its source, so the interpreter no longer has
to be constrained.
That lets us drop the UV_PYTHON=3.13 workaround added in #2801: the
_set_uvx_python_compat() helper and its call sites are removed from the
claude-code, codex, cursor, and cursor-cli daemons, along with the tests
that pinned that behaviour. Dropping the pin costs nothing — litellm
publishes no macOS wheels at all, so macOS builds from the sdist on every
version regardless, while Linux now gets a real cp314 wheel instead of a
source build.
Also strengthen the build-api-python-versions CI matrix. It previously
ran only `uv build`, which just packages the source and passes even when
the dependency set cannot install or import on the target interpreter --
it would not have caught this. It now installs into a fresh venv,
byte-compiles, and runs an import smoke test on each version.
Verified on CPython 3.14.4 with UV_PYTHON unset: litellm 1.93.0 installs,
the Rust bridge builds, and hindsight_api plus the engine import cleanly.
