about

nx_fio.nx -- canonical sovereign file operations: unlink (delete) + existence check. Importable (no main). Retires Remove-Item / rm. rename is already canonical (sys_renameat in nx_syscalls). unlinkat x86_64=263 is passed DIRECTLY (the fsync-74 / fstatat-262 / unlinkat-263 precedent: a raw x86_64 number not in the rv64->x86 swap table passes through untranslated). AT_FDCWD=-100, flags=0. Returns 0 on success, -errno on failure. license_tier: ORIGINAL
