# Reusable workflow: verify the linux-aarch64-musl prebuilt
# installs + loads on Alpine aarch64. Same shape as the x86_64
# musl lane — source-builds Rakudo inside the container via
# rakubrew on a `ubuntu-22.04-arm` host pulling the native aarch64
# alpine image.
#
# Rakudo source-build (~10-20 min on first run) is split from the
# test phase so a test failure doesn't bust the cache. See the
# x86_64 lane comment for the sequencing rationale.
