### 2.9 `app/alerts` — алерты
-- **Детекторы** превращают события runtime/pipeline/хоста в `AlertEvent(kind, service, payload)`; пороги — `config/alerts.yaml`.
-- **Дедупликация**: ключ `kind + service`; открытый алерт с тем же ключом → `count += 1`, исходные сообщения
- редактируются (не чаще раза в 10 мин), новые не шлются.
-- **Рассылка** всем активным участникам (кроме 🛡 — только администраторам) с учётом лимита Telegram (~30 msg/s,
- очередь отправки); `alert_deliveries` хранит `chat_id`/`message_id` — чтобы обновлять счётчик и отвечать «✅ восстановлено».
-- **Восстановление**: детектор сообщает, что условие прошло → `resolved_at`, ответ на исходные сообщения.
-- **Список**: активные + история 7 дней, пагинация.
+- **Детекторы** (`detectors.py`) — чистые функции «наблюдение за раунд + история снапшотов → условия, которые
+ выполняются сейчас»: 💥 краш (выход ≠ 0), 🧠 OOM, 🔁 ≥ 3 рестарта за 10 мин, 🩺 unhealthy, 🔥 CPU > 80 % или
+ RAM > 90 % на протяжении минуты, 💾 < 10 % свободного места на разделе тома бота, 🔌 Docker API недоступен > 5 мин.
+ Пороги — `config/alerts.yaml`. Монитор (`monitor.py`) вызывается после каждого раунда снапшотов (15 с).
+- **По состоянию, а не по событиям**: сервис сверяет условия с открытыми алертами — новое открывает алерт, пропавшее
+ закрывает. Пропущенное событие не теряет алерт, а бесконечный рестарт остаётся одним алертом.
+- **Дедупликация** (`service.py`): ключ `kind + service`. Условие, вернувшееся в течение 10 мин после закрытия, снова
+ открывает тот же алерт с `count += 1`: исходные сообщения редактируются, новые не шлются.
+- **Разовые события** (🛡 атака через агента; 📦 CD и ⛔ отказ после деплоя — после #11/#13) открываются сразу
+ закрытыми; повтор в окне 10 мин — тоже счётчик.
+- **Рассылка** (`broadcast.py`) — всем активным участникам, 🛡 — только администраторам; ~25 сообщений/с,
+ `RetryAfter` пережидается, заблокировавший бота участник пропускается. `alert_deliveries` хранит
+ `chat_id`/`message_id`, чтобы обновлять счётчик и отвечать «✅ восстановлено» на исходное сообщение.
+- **Сообщение**: тип, сервис, время, хвост лога (30 строк), кнопки «📜 Логи», «🩺 Статус», «📋 Список алертов».
+ Кнопки открывают экран новым сообщением, чтобы не затирать алерт.
+- **Список**: активные сверху, затем история за 7 дней, по 10 на страницу; 🛡 в общий список не попадает.
+- **Если Docker недоступен**, оцениваются только 🔌 и 💾: алерты контейнеров не закрываются вслепую.
