Widget panel

Use show_widget with presentation.target: "node_panel" to create a hosted widget document and present it on an eligible connected Mac. This is the normal agent path.

The Canvas tool is limited to direct panel control:

• present: show the panel, optionally with a hosted document path or local app scheme.
• hide: hide the panel.
• navigate: navigate the visible panel to a hosted document path or local app scheme.

Do not invent local file paths or arbitrary external URLs. Hosted documents use the capability-scoped /__openclaw__/canvas/documents/... route returned by show_widget. A2UI content renders on session boards and loads renderer assets from /__openclaw__/a2ui.

If plugins.entries.canvas.config.host.enabled is false, hosted widget documents, A2UI renderer assets, and node-panel presentation are disabled together.
