note: miniconda3 (installed from the *.pkg distribution) did not work, so I built this with miniforge3 for Mac OSX AMD64 (installed via the shell script) instead.

I think the issue was that pip did not recognize the miniconda environment as an arm64 platform, and thus did not pull the scipy arm64 wheels, and so fell back onto a build from *.tar.gz which failed due to missing BLAS. Installing openblas from conda also did not work, but changing the installation to miniforge did work.
