Rich Output Protocol

Assistant output can carry a small set of delivery/render directives:

MEDIA: for attachment delivery
[[audio_as_voice]] for audio presentation hints
[[reply_to_current]] / [[reply_to:<id>]] for reply metadata
[embed ...] for Control UI rich rendering

These directives are separate. MEDIA: and reply/voice tags remain delivery metadata; [embed ...] is the web-only rich render path.

`[embed ...]`

[embed ...] is the only agent-facing rich render syntax for the Control UI.

Self-closing example:

[embed ref="cv_123" title="Status" /]

Rules:

[view ...] is no longer valid for new output.
Embed shortcodes render in the assistant message surface only.
Only URL-backed embeds are rendered. Use ref="..." or url="...".
Block-form inline HTML embed shortcodes are not rendered.
The web UI strips the shortcode from visible text and renders the embed inline.
MEDIA: is not an embed alias and should not be used for rich embed rendering.

Stored Rendering Shape

The normalized/stored assistant content block is a structured canvas item:

{
  "type": "canvas",
  "preview": {
    "kind": "canvas",
    "surface": "assistant_message",
    "render": "url",
    "viewId": "cv_123",
    "url": "/__openclaw__/canvas/documents/cv_123/index.html",
    "title": "Status",
    "preferredHeight": 320
  }
}

Stored/rendered rich blocks use this canvas shape directly. present_view is not recognized.
