kiwisolver 1.5.1 for slicc WASIX CPython 3.15 (cpython-315-wasm32-wasix). Since the Python 3.15 flip (homescoop#761) this is latest; the cp314 builds stay on npm by exact version (release notes).
kiwisolver/_cext.cpython-315-wasm32-wasix.so is a dylink.0 side module that python.wasm loads by dlopen.
Build: in homescoop's CI from the PyPI sdist, with wasixcc++ (legacy wasm exceptions, PIC). It is built against @ai-ecoverse/wasix-python 3.15.0-1's headers and the libc++ headers of wasix-sysroot 2025.9.30-38's sysroot-ehpic, the C++ runtime that python.wasm exports.
Python range:>=3.15.0-1 <3.15.1.
Call signatures: the no-argument methods and strength getters take CPython's second parameter (kiwisolver-wasm-call-signatures.patch, homescoop#588).
