matplotlib (unpinned, in CIBW_TEST_REQUIRES) pulls in pillow with no version constraint; pip reached past our registry's published riscv64 pillow wheel to a newer sdist-only release, which fails to build with RequiredDependencyException: jpeg (no libjpeg-devel in the image). Same pattern as the existing cryptography/rfc3161-client entry on this same line, and as gotcha 291.
tests/test_cli_describe_api.py imports httpx, which huggingface-hub 1.x pulls in and 2.x replaced with httpx2. Upstream's uv.lock tests against huggingface-hub 1.32.0, so match it.
The suite downloads kernels-community/relu and kernels-test-untrusted/ci-test-kernel from the Hub, which publish x86_64/aarch64 (and CUDA-only) builds only, and kernelizes on "cuda"; upstream runs it on GPU runners only, so these fail with "Cannot find a build variant for this system" on riscv64. On cp314t, kernels.variants also drops every arch kernel on free-threaded Python <3.15, which the variant-resolution tests' hard-coded x86_64/aarch64 systems don't account for (arch-independent: upstream's test CI never runs a free-threaded interpreter), so those are deselected on that leg only.
Both manylinux_riscv64 legs (cp38-abi3 and cp314t) failed the CLI-without-torch check with AttributeError: module 'torch' has no attribute 'version'. pytest exercises torch heavily enough that it writes files into its own installed site-packages/torch tree; pip's RECORD-based uninstall only removes what it itself installed, leaving that tree behind as an empty-but-importable namespace package instead of a clean ModuleNotFoundError. Force the directory gone before re-importing kernels, matching the clean removal uv's uninstall gives upstream's own CI.
_publish-wheel.yml now requires a matrix input (main's "publish: Validate effective wheel targets"), but this PR branch forked before that landed and kernels has never been merged to main, so build-kernels.yml never picked up the matching one-line update every already-published package's workflow got. The merge ref combines the new required-input _publish-wheel.yml with this branch's old build-kernels.yml, so any run has failed startup with "Input matrix is required, but not provided". Pass it the same way the mass-update commit did for every other package's publish job.

kernels0.18.0Compiles the
kernels._rustPyO3 extension (kernel metadata, locking, digest and signing logic from thekernels-commoncrate, with rustls/aws-lc). Upstream publishes 28 Linux wheels and no riscv64 one.Mirrors upstream's
publish_kernels.ymllinuxjob and the test steps of itstest_kernels.yaml, in the same shape as the existingkernels-dataport.Differs from upstream
