nx_probiome_test.nx -- smoke for nx_probiome (R6, cross-kingdom beneficial-microbe engine, v2 widened to organisms in general). Proves: - a data-driven catalog spanning FOUR host kingdoms AND four microbe domains (bacteria / yeasts / molds / mycorrhizal fungi); - the "One Health" keystone (B. subtilis benefits 3 kingdoms); - a GENERATIVE recommender that is SAFE-BY-CONSTRUCTION; - TWO genus-level liar-kill pairs: Bacillus subtilis vs B. cereus (toxin) and Aspergillus oryzae (koji) vs A. flavus (aflatoxin); - LIAR-KILLS: pathogen, toxigenic bacterium, toxigenic mold, AMR opportunist, host mismatch, unknown (fail-closed) all REFUSED; - the recommender never returns an AMR additive or an aflatoxin mold even when it nominally fits the target. Exit code = failed assertion number; 0 = all pass.
