Восстановлено из транскрипта сессии после потери рабочего дерева на сервере сборки. Что внутри: - четыре новых модуля прошивки (приём, сборка исходящего, меню Messages); - правки существующих файлов в виде скриптов, с порядком применения; - инструменты стенда: снятие экрана рации по USB, дамп кадров, эталонная сборка пакета; - NOTES.md: что проверено в эфире, что не доделано, где грабли. Работало в эфире в августе 2026: данные ходят в обе стороны в режиме хотспота, рация принимает SMS и показывает на экране. Отправка собрана и сверена с эталоном сервера побайтово, но в эфире не проверялась. Claude-Session: https://claude.ai/code/session_01GJtvG5WwqYNe1b7s9LLtgy

Drawing counters on the screen turned out to be unreliable: the notification is
|

overwritten by the normal screen redraw, so a screenshot usually shows nothing even
|
|
when reception is happening. Instead the counters are mirrored into the tail of the
|
|
raw audio buffer, which the CPS protocol can read out at any moment (area 7).
