# Builds what is pushed, not the working tree: the build host pulls master of
# svc-core and contracts under ~/dev/yukart/; the signal layouts are compiled in
# from contracts' signals.json, so a registry change needs a redeploy. Native like
# orin-status, on the preferred build host (check-glibc.sh gates it either way).
