+# PyPI's scikit-learn-intelex wheel is Apache-2.0 and links only against the daal
+# (oneDAL) shared libraries at runtime (Requires-Dist: daal==<same version>) - no dpctl, no
+# direct SYCL/MKL linkage (readelf -d on the real wheel's _onedal_py_host/_daal4py .so files
+# shows no libsycl/libmkl NEEDED entries). setup.py's own arch_dir fallback
+# (`plt_dict.get(machine, machine)`) and optional dpcpp/no_dist switches (NO_DPC/NO_DIST) are
+# already CPU-generic; upstream's own docs (doc/building-from-source.rst) state it can be
+# "built from source to provide accelerated routines for other platforms such as ARM and
+# RISCV". This builds oneDAL from source once per version (same recipe as build-daal.yml)
+# and reuses it across the interpreter matrix to compile the daal4py/_onedal_py_host
+# extensions, instead of waiting on Intel's x86_64-only wheel.
+# Based on: https://github.com/uxlfoundation/scikit-learn-intelex (no upstream CI builds
+# this wheel; ci.yml's sklearn_lnx job runs an equivalent `python setup.py install` for tests
+# only, against an oneDAL nightly build artifact).
