1// nx_gate.nx -- canonical gate I/O. ONE definition of the gate stdout helpers (gw/gn/gwb), replacing the ~23 ad-hoc
2// copies scattered across runtime gates. Imports the CANONICAL syscall surface (nx_syscalls.nx), not the syscalls.nx
3// alias -- part of retiring alias-juggling. A gate imports this and writes results; it never re-rolls gw/gn again.
4// license_tier: ORIGINAL
