# Reusable single-build workflow for the Linux JAX wheel flow.
#
# This workflow is called once per release matrix cell from
# test_linux_jax_wheels_partial.yml
#
# Built shape:
#   - One build/ci_build invocation for one python_version and jax_ref
#     matrix cell.
#   - Uploads the resulting wheels to the multi-arch release bucket.
#   - Runs the JAX test subset against the published multi-arch index.
