about

nx_mmap_probe.nx -- pins the sovereign large-immediate/mmap bug: sovereign-built nxasm bails pre-pass0 on 2.36MB inputs while the gcc-built one reads fine. Probes sys_mmap at small/2.4MB/16MiB (the NXASM_BUF constant). Run VIA nx_sov_build_run; trust its run-exit= line ONLY (bash $? lies). exit 0 = all mmaps good (bug elsewhere: read loop) ; 1/2/3 = which size failed. license_tier: ORIGINAL
