summary: |
  Pryon has a real streaming surface but no asynchronous event surface. There are no
  outbound webhooks, no event bus, no message broker and no AsyncAPI document — nothing to
  subscribe to. What Pryon does publish is in-request streaming: two WebSocket operations and
  three server-sent-event operations that stream the tokens and events of a single
  conversational turn back to the caller that opened it. This artifact records that surface
  honestly rather than dressing it up as an event-driven API.

  note: The Q1 2026 release made real-time streaming for Symphony orchestration workflows
    production-ready, and the App Builder chatbot streams responses in real time.
gaps:
- No AsyncAPI document is published for the WebSocket or SSE surfaces.
- No outbound webhooks — a Pryon consumer cannot register a callback URL for ingestion,
  sync, feedback or approval events. Ingestion and sync progress are polled through the
  Content and Analytics APIs instead.
- Because there is no event surface, the asyncapi scoring family is not applicable here;
  no AsyncAPI or Webhooks pointer is wired in apis.yml.
