 ## Текущая задача
+[+] **Android: автопередача рации по уровню сигнала** — 08.10.2026:
+    режим VAD/уровень, два порога dBFS, живой измеритель из общего radio_audio и prefetch 600мс.
+    Вкладка рации временно держит микрофон для измерения при выключенной автоматике; уход со вкладки/пауза освобождает этот захват.
+    Оба детектора используют прежнее окно foreground/screen/background; PTT имеет приоритет, RX-защита остаётся общей.
+    Настройки сохраняются одним DataStore edit и передаются одним заданием uasync с подтверждением до старта capture.
+    Кнопка панели показывает выбранный режим и сохранённое включение; JNI принимает явный OFF/VAD/LEVEL.
+    Для уровня на кнопке — значок эквалайзера; удержание VAD/уровня открывает мини-блок режима, измерителя и порогов прямо у кнопки.
+    Выбор режима — две кнопки VAD/уровень с областью нажатия от 48 dp, без вложенного выпадающего меню; выбор записывается в лог radio.
+    Добавлены русские/английские строки и диагностика. assembleDebug (arm64-v8a/x86_64), 21 JVM-тест — PASS.
+    На физическом устройстве новый режим пока не проверен.
+
 [+] **ChatGUI: автопередача рации по уровню сигнала** — 08.10.2026:
     выбор VAD/уровень, RMS 20мс после AEC до компрессоров, два порога dBFS (-35/-45 по умолчанию),
     подтверждение 40мс и общая задержка отключения. Измеритель работает при включённой рации даже без автоматики.
