Release 3.8.2.3: cheaper poll I/O, batched macOS sysproxy, no Connect Clone.

Trust corebin cache without Stat; batch networksetup; ActiveProxyURI instead of Config.Clone.

 Некоторые AV (Bkav, Microsoft Wacapew/Wacatac, Ikarus Trojan.WinGo.Agent, Google, Trapmine) часто помечают **любые** неподписанные Go-бинарники с сетью и сменой системного прокси.
 
+В 3.8.2:
+- при неожиданном падении ядра снимается системный прокси и sentinel;
+- логи ядра и проверка туннеля (Probe) в UI; connect-on-launch и автопереподключение;
+- подписка удаляет устаревшие ноды прошлой синхронизации; «Лучший» без soft-ok UDP;
+- трей (Windows), CI workflows, REQUIRE_CODESIGN для релиза; Android gated Naive/AWG + sync версии;
+- 3.8.2+2: иконка в macOS Dock — буква N цвета морской волны при подключении, исходная при отключении;
+- 3.8.2+3: poll без os.Stat ядер + кэш host; Darwin sysproxy batch; Connect без Config.Clone.
+
+В 3.8.1:
+- меньше нагрузка в простое: лёгкий опрос интерфейса без полного клонирования конфига, кэш путей к ядрам, лог с лимитом размера;
+- список серверов в UI не пересобирается без изменений; интервал опроса 4 с;
+- быстрее и точнее пинг (учитывается протокол профиля; лёгкий разбор AWG Endpoint);
+- AWG-прокси копирует трафик через буферный pool; PingAll и установка cores используют несколько ядер CPU;
+- 3.8.1+1: первая сборка линейки 3.8.1.
+
 В 3.8.0:
 - единый GUI-контроллер `apphost` для Windows и macOS (без дублирования логики);
 - безопасный lifecycle Connect/Disconnect (ожидание Stop, mutex Windows sysproxy);

 Without these env vars, packmac uses **ad-hoc** signing (`-`) — fine for local/dev.
 
+For a **release gate** (fail if unsigned):
+
+```bash
+export REQUIRE_CODESIGN=1
+export NAVIS_CODESIGN_IDENTITY="Developer ID Application: Example Ltd (TEAMID)"
+./scripts/build-macos-arm64.sh

+In-app macOS updates **do not** re-sign with ad-hoc `-` (that would strip Developer ID). They only re-sign when `NAVIS_CODESIGN_IDENTITY` is set to a real identity.
 ## Windows
 
 Sign `Navis.exe` with Authenticode (EV or standard code signing cert):
