nx_ferment_invent_test.nx -- smoke for nx_ferment_invent (R5). Proves generative fermentation design that is SAFE BY CONSTRUCTION: - invents a viable yogurt: safe, warm, sets within target (1-5) - the invented recipe RE-VALIDATES safe under R0 (6) - REFUSES a too-cold anaerobic batch (never acidifies in time) (7) - REFUSES an under-salted vegetable ferment (botulism risk) (8) - invents a viable kraut once salt is adequate (9) Exit code = failed assertion number; 0 = all pass.
