# build-node โ€” cyb for ubuntu and windows, built on the cybernode.
#
# The cyb workspace reaches into ~21 sibling repos GitHub never sees, so
# CI cannot build it. deimos (the quietest cybernode: 8 cores, 62G) can:
# this script rsyncs the workspace there, builds linux natively and
# windows via cargo-xwin (MSVC cross, SDK auto-fetched), and brings both
# artifacts home.

# Node prerequisites (bootstrapped once): rustup stable +
# x86_64-pc-windows-msvc target, clang/lld, cargo-xwin, and the bevy apt
# set (alsa, udev, x11, wayland, xkbcommon).
#
# Builds run under nice: the node's day job (bostrom) keeps its cores.
