nx_supplement_check.nx

nx_supplement_check.nx -- C5.2 milestone: argv-aware CLI tool. The standalone "lab analyst's tool" that closes the bits-up usability arc. Takes a peak file path on the command line, runs the full supplement-adulterant detection pipeline, emits JSON to stdout, and returns banned-count as exit status so shell scripts can branch on it. USAGE: nx_supplement_check <peak-file> EXAMPLES: $ cat > /tmp/sample.txt <<EOF # LC-MS peak list 280.18 10000 742.3 102.13 8000 45.2 EOF $ qemu-riscv64-static nx_supplement_check.elf /tmp/sample.txt {"sample_id":"argv-supplied","method":"LC-ESI+-MS",...,"recommendation":"REJECT"} $ echo $? 2 # number of BANNED ingredients detected EXIT CODE CONVENTION: 0 no banned, no restricted, all peaks identified (ACCEPT) 1 bad arguments / file missing / parse error N number of banned ingredients (REJECT or REVIEW recommended) This makes shell pipelines natural: nx_supplement_check $peaks_file && echo "lot OK" || echo "REJECT"
