1// nx_world_class_test.nx -- prove every named blocker is gone.
2//
3// One smoke that exercises arith / classical / tactics / rewriter /
4// emitter end-to-end via v2 kernel. Per user 2026-05-15: "no losses".
5//
6// Each test gets an assertion number; main() returns it on first
7// failure (per nx_smoke_lib.sh convention). Returns 0 only when all
8// pass.
