Переведены в AtomicBoolean и AtomicInteger. +2. Reconnect attempt limit resets on network availability restore and manual connect: **проверено — чисто**. `reconnectAttempt.set(0)` в `onNetworkRestored()` и `connect()`. +3. `connect()` awaits `gateway.ready`, UI shows connecting state properly: **проверено — чисто**. `gatewayClient.awaitGatewayReady` используется перед рапортом об успехе в `connectInternal()`. +4. `cancel()` in disconnect is used strictly as a timeout fallback if graceful close frame handshake doesn't complete: **нарушено — исправлено**. Был прямой вызов `close()` и сразу `cancel()`. Добавлен таймаут (ожидание через `closeLatch.await`) в fallback-корутине. +5. `gatewayReadyDeferred` race is fixed atomically: **проверено — чисто**. Локальная копия читается внутри `synchronized` под общим локом. +6. Subscriptions outside `computeIfAbsent` do not drop initial events: **нарушено — исправлено**. Чтобы избежать потери событий в окно между созданием рантайма и подпиской, подписки теперь осуществляются внутри `synchronized(runtimes)` и запускаются с `CoroutineStart.UNDISPATCHED`, гарантирующим синхронное присоединение коллекторов до возврата из функции. +7. Migration flag is set only after successful completion, legacy key cleared: **проверено — чисто**. Флаг устанавливается внутри `edit { ... }` в конце успешного обхода. +8. `ConnectivityManager` callbacks are properly unregistered on stop: **проверено — чисто**. Отписываются в `stop()`. +9.

Служба никогда не остаётся висеть бесконечно. +- **Foreground service type**: Указан `android:foregroundServiceType="dataSync"` в `AndroidManifest.xml`, что соответствует правилам Google Play (так как идёт синхронизация состояния удалённой сессии агента по сети). +- **Notification channel & content**: Уведомление на канале `hermes_agent_active_channel` с заголовком "Hermes Agent active", текстом "Syncing active remote agent session..." и `PendingIntent` для возврата в приложение. +- **Permissions**: В манифест добавлены `FOREGROUND_SERVICE`, `FOREGROUND_SERVICE_DATA_SYNC`, `POST_NOTIFICATIONS`. +- **README.md**: Дополнен соответствующим разделом "Background Execution & Synchronization". + +--- + +## Вердикт оркестратора + +### 1.
