source: Webhook management operations and event-type enumerations read from the first-party specs openapi/dolby-millicast-api-openapi.yml
  and openapi/dolby-optiview-live-openapi.yml, plus the Millicast REST APIs & Webhooks changelog https://optiview.dolby.com/docs/millicast/changelog/changelog-rest-apis/
  and the sample receiver github.com/millicast/samples-millicast-webhooks.

note: 'Dolby OptiView publishes NO AsyncAPI document for any product - there is none in the docs site,
  none in the public github.com/THEOplayer/documentation source repo, and no /asyncapi.yaml on any host.
  It does ship a real, contract-declared webhook surface on two of its products, captured here as a webhook
  catalogue. Nothing in this file was authored on Dolby''s behalf: every event name below is an enum value
  in a Dolby-published OpenAPI document.'

  security:
    signing: true
    detail: Each webhook carries a base64 signing secret returned on the WebhookModel; refreshSecret on
      update rotates it.

  security:
    signing: true
    detail: A per-webhook signing secret is retrievable at GET /webhooks/{id}/secret.
  delivery_logs: true

    delivery observability in the surface.
gaps:
- No AsyncAPI or CloudEvents document published for either surface.
- No retry or backoff policy documented for webhook delivery on either product.
- No webhook surface at all on Dolby OptiView Ads, the Ad Engine, the Director API or Advanced Analytics.
