nx_bigint.nx

nx_bigint.nx -- KAT GATE for the multi-precision integer primitives (nx_syscalls import chain). 2026-07-09: the bi_* primitives moved to nx_bigint_lib.nx (importable, zero-imports) -- this twin and bigint.nx were code-identical and BOTH carried main(), making the primitives unimportable into any main-bearing binary. This file keeps the ORIGINAL smoke battery as the standing gate on the nx_syscalls chain; bigint.nx gates the syscalls.nx chain. Consumers import nx_bigint_lib.nx (transitively via this file still works). expect_exit: 0 license_tier: ORIGINAL
