al_* = калибровочный датасет центральной LUT-ноги для замены frozen-узлов.
Стационарный тон: A_k/res_k = B.12 xv => формула = B.12 точно; остаток = маска.
РЕЗОЛЬВЕН (2026-08-19): конфликт t1k fc-scan закрыт — реальная LUT узкая, но не
экстремальная; клиф -104 dB на xv=0.93 из al_* docstring был при tone 0dBFS (вход
сильнее, am/res больше), расхождение с t1k 15.6 dB = разные входные уровни/цапляби.
