  Amazon Nova publishes NO AsyncAPI document and NO HTTP webhooks. It does have a real, documented
  asynchronous event surface, and it is delivered over Amazon EventBridge rather than by callback:
  Amazon Bedrock emits job state-change events to the default event bus with source `aws.bedrock`,
  and a consumer writes a rule to route them to Lambda, SNS, SQS or an HTTP API destination. This
  is the cloud-native equivalent of a webhook subscription, recorded honestly as what it is — the
  subscriber owns the rule, and Amazon does not POST to a caller-supplied URL.

events:
- detail_type: Batch Inference Job State Change
  source: aws.bedrock
  description: >-
    Status change on a batch inference job — the offline, high-volume path for Amazon Nova
    understanding models.
  correlates_with: GetModelInvocationJob
  resources: 'arn:aws:bedrock:<region>:<account>:model-invocation-job/<id>'
- detail_type: Model Customization Job State Change
  source: aws.bedrock
  description: >-
    Status change on a fine-tuning / customization job. Amazon Nova Pro, Lite, Micro and Canvas
    support customization.
  correlates_with: GetModelCustomizationJob

gaps:
- >-
  StartAsyncInvoke — the operation Amazon Nova Reel video generation runs on — has NO documented
  EventBridge event. A caller must poll GetAsyncInvoke, which is exactly the polling the
  EventBridge page says events exist to avoid.
- >-
  Synchronous inference (InvokeModel, Converse) emits no events, which is expected for a
  request/response surface.
