    WebhookEventEnvelope:
      title: WebhookEventEnvelope
      type: object
      description: |
        Common wrapper present on every outbound webhook event. The `data` field
        is polymorphic; its schema depends on the value of `type`.
      required:
        - id
        - type
      properties:
        id:
          type: string
          description: |
            Globally unique event identifier. Uses the TypeID format with the
            prefix `whe_` followed by a UUIDv7-derived suffix
            (e.g. `whe_01j8e4k2abc123def456`). Use this field to deduplicate
            deliveries if your endpoint receives the same event more than once.
          example: whe_01j8e4k2abc123def456
        type:
          type: string
          description: |
            Dot-notation event type string. Use this field to route the event to
            the appropriate handler in your integration.
          example: contract.assignment.updated
          enum:
            - contract.producer_status.updated
            - contract.assignment.updated
            - contract.assignment.deleted
            - contract.assignment_change.updated
            - contract.assignment_change.deleted

            - contract.deleted
            - contract.responsible_party.updated
