  "component": "PendingUpdateNotice",
  "props": {

  }
}

Props

Prop	Type	Required	Notes
since	string (date-time)		ISO 8601 date the source changed. max length 40
id	string		Anchor id for in-page links (letters, digits, dashes). max length 40

Text fallback

What a text-only client, an unknown renderer or a plain-text channel shows for the example above.

The source of this lesson changed on 9 October 2026; an update is under review.

Invalid props

A node whose props fail the schema never breaks the page: the renderer shows the plain-text fallback instead (and logs the issues in development).

{
  "since": 5
}

Issues:

• /since expected string, got integer

Rendered as:

The source of this lesson changed; an update is under review.
