name: COSMOPlat IoT event and streaming surface
summary: >-
  COSMOPlat's event surface is MQTT publish/subscribe on the IoT development platform,
  plus a rule engine that can forward matched data to an HTTP API or a message queue.
  There are no HTTP callback webhooks with a published registration API, and no
  provider-published AsyncAPI document.
surfaces:
- kind: mqtt-subscribe
  name: Tenant telemetry subscription
  host: iot-mqtt.cosmoplat.com
  port: 11883
  tls: not documented
  auth: MQTT username = 企业ID (enterprise ID), password = 企业密钥 (enterprise secret),
    both issued in 企业中心 on the IoT platform
  topics:
  - 'tgwl/telemetry/{enterpriseId}/#'
  - 'tgwl/telemetry/{enterpriseId}/{productIdentifier}'
  docs: https://www.cosmoplat.com/help/detail/304/1064
  prerequisite: The transport component (传输组件) must be activated by the platform system
    administrator before a tenant can subscribe.
- kind: mqtt-publish
  name: Device telemetry ingest
  host: iot.cosmoplat.com
  port: 1883
  tls: not documented
  topics:
  - v1/devices/me/telemetry
  docs: https://www.cosmoplat.com/help/detail/304/1064
- kind: rule-engine-forwarding
  name: Rule chain data forwarding
  description: >-
    The platform overview states the rule engine can be configured to push matched data
    to an API or to an MQ message queue. The rule-chain CRUD operations are published in
    the API reference, but the forwarding target configuration schema is not.

gaps:
- id: no-tls-mqtt-port
  detail: Only plaintext MQTT ports (1883 device, 11883 tenant) are documented. No
    MQTTS/8883 port or TLS guidance is published.
- id: no-published-asyncapi
  detail: COSMOPlat publishes the broker hosts, topics and an example payload in prose
    but serves no AsyncAPI document. Publishing one at a stable URL would make this
    surface machine-discoverable.
- id: no-per-product-payload-schema
  detail: Telemetry payload keys are thing-model telemetry point identifiers configured
    per product; no schema is published per product.
