+# ⛔⛔⛔ ЛЕГАСИ (2026-08-16) — СТАРЫЙ IoT (k8s-деплой). НЕ ПРИНИМАТЬ ВО ВНИМАНИЕ.
+# Актуальное: HISTORY/2026-08-16-session-log.md
+
+# Создано: 2026-04-12
+# EMQX MQTT-брокер для IoT-сервиса (namespace: sless).
+#
+# Архитектура:
+#   IoT Device → MQTT CONNECT → EMQX (HTTP auth → iot-operator:9090/internal/mqtt/auth)
+#   EMQX → MQTT PUBLISH → iot-mqtt-bridge (paho subscriber) → shared-SQS queue iot-telemetry
+#   SQS → iot-sqs-consumer → Postgres
+#
+# EMQX 5.x конфиг через emqx.conf (HOCON формат), монтируется как ConfigMap volume.
+#
+# Порты:
+#   1883 — MQTT (plaintext)
+#   8083 — MQTT over WebSocket
+#   18083 — EMQX Dashboard (admin/public по умолчанию — менять в prod!)
+#
+# Применение: kubectl apply -f deployments/k8s/emqx.yaml
