Proves structure -> taste prediction + the MEASURED EXCEED (generalises to molecules outside any ingredient table): - 6 grounded reference molecules classify correctly (1-6) - sweetness POTENCY is read from structure (7-8) - a NOVEL molecule (in no table) is classified from structure (9-10) - a structurally inert molecule -> NONE (11) Exit code = failed assertion number; 0 = all pass.
