nx_flavor_pairing_test.nx

nx_flavor_pairing_test.nx -- smoke for nx_flavor_pairing (T4). Proves shared-compound pairing + the MEASURED EXCEED (scores any pair, not just hand-listed ones): - shared-compound counts are correct (1-3) - flavor-network principle: a fruity pair (shared esters) out-scores a fruit+allium pair (no shared compounds) (4) - identical sets score 1000; affinity bounded (5-7) - a NOVEL ingredient gets a real computed affinity, and a non-sharing novel ingredient scores 0 (8-10) -- generalisation the table lacks Exit code = failed assertion number; 0 = all pass.
