+ * ============================================================================
+ * TRUE ITN v18.0 — NEURAL DYNAMICS PRO
+ * ============================================================================
+ * Профессионально оптимизированная инвертируемая нейронная архитектура
+ *
+ * Ключевые особенности:
+ * • INN (Invertible Neural Network) драйвер с attention и памятью
+ * • Динамические веса, генерируемые на лету из состояния
+ * • 4 независимых ротора с фазовой модуляцией и резонансом
+ * • 16-head attention с адаптивной интерференцией
+ * • Полная обратимость с верификацией команд
+ *
+ * Оптимизации производительности:
+ * • LUT для sin/cos с линейной интерполяцией (5-10x быстрее)
+ * • TypedArray pooling для zero GC аллокаций
+ * • Early-exit для интерференции (пропуск слабых сигналов)
+ * • O(1) lookup таблицы для алфавита и роторов
+ * • Адаптивная сложность на основе confidence
