# Install zef into the active rakubrew Rakudo. Runs AFTER the
# Rakudo cache save (so zef doesn't end up in the cached payload)
# but BEFORE any `zef install`. Takes ~30s.
#
# Why install zef every run instead of caching it: zef lives in
# `versions/moar-*/install/share/perl6/site/`, the same dir that
# zef tracks "already installed" state in. Caching site/ makes
# `zef install .` short-circuit with "All candidates are currently
# installed" on cache hit — Build.rakumod doesn't run, the
# Notcurses-Native prebuilt isn't staged into ~/.local/share/, and
# dlopen fails at test time. Cleaner to keep site/ out of the
# cache entirely and pay 30s/run for a guaranteed-fresh zef state.
#
# Honours $RAKUBREW_HOME (default $HOME/.rakubrew) — matches the
# default used by build-rakudo.sh.

# not yet include shims (e.g., the `Add shims to PATH` step might
