mss-relay (cmd/mss-relay): TCP-релей с двухступенчатым MSS для РФ-плеча mtg. Слушает с нормальным MSS (клиентский ClientHello доезжает целиком), на время первого ответа сервера ставит TCP_MAXSEG=92 (анти-DPI для ТСПУ), потом возвращает полный размер - приём telemt client_mss_bulk, но на уровне релея. Цель - убрать второй порт и iptables-клейм, свести mtg-плечо к одному порту как :443 у telemt. ВАЖНО: на живом тесте (pr7, 27.08) сотовый Android по dd НЕ подключился без постоянного клейма - ему мелкий MSS нужен весь сеанс, а не только на рукопожатие. iPhone/Windows/ee при этом работали. Бинарь готов и оттестирован, но в проде пока socat+клейм: релей ждёт решения (двойной шейпинг с MTG_DD_SHAPE или отдельный порт под ee). 4 теста на порядок переключения MSS и прозрачность данных. proxy_stats: RejectReason-счётчики (initial_bytes/secured_handshake/client_hello/ replay/welcome) в /stats. Раньше в статистике были только успешные подключения - клиент с обрезанным рукопожатием (Windows FakeTLS) был невидим, ловили tcpdump'ом. Теперь отказы видны в JSON, watchdog сможет алертить по росту.

Summary
dd) handshakes before FakeTLS parsing;ee) clients.Validation
httpbin-backed tests (mtglib/TestHTTPSRequest,network/TestRealHTTPRequest).The production binary built from this branch is deployed to the mtg nodes behind
pr5–pr8relays. DD response shaping remains disabled in production because Android connectivity is faster and stable without the experimental fragmentation layer.
