nx_xlate_mt_gate.nx

nx_xlate_mt_gate.nx -- MEASURES the data-driven RU<->EN engine on a HELD-OUT test set. NO fake green: loads knowledge/xlate/{xlate_lex.tsv, xlate_morph_ru.tsv, xlate_testset.tsv}, builds the engine, translates every held-out sentence, and reports unigram PRECISION + RECALL (clipped, per-mille integer, no float) and EXACT-match count -- then re-scores the SAME set through the OLD 16-word nx_ruen_translate stub to prove the leap. verdict GREEN iff the new engine's unigram precision >= 300 per-mille AND strictly beats the old stub.
