 Upon connecting a `"connect"` event is emitted with the session the connection was made under. This is the primary mechanism a user agent discovers its own session having been rotated into a new one, which also happens when the access level of the account associated with the session changes.
 
 After the `"connect"` event the user agent will start to receive updates to resources it has access to that has changed. There is no filtering for what resoucres the user agent receives updates for at the moment as there's not enough events to justify the complexity of server-side subscriptions and filtering.

-## Id and order
-
-Events are guaranteed to be delivered in order, and to maintain consistency the server provides the following guarantee: Any entities fetched after receiving a response from `/api/last-event-id` will include updates from all events up to and including the `id` received from the response.
-
-This means that a client can fetch an up to date and live representation of any API entity by first fetching the last event from `/api/last-event-id`, and then in parallel fetch any entities as well as opening the `/api/events` stream with the `lastEventId` query param set to the value received from the `/api/last-event-id` endpoint.
