QA — open-gen-ui-advanced

Scope

Manual QA for the advanced Open Generative UI demo. Builds on open-gen-ui by adding openGenerativeUI.sandboxFunctions (evaluateExpression, notifyHost) that the agent-authored iframe can invoke via Websandbox.connection.remote.<name>(...).

Happy path

• Navigate to /demos/open-gen-ui-advanced.
• Composer shows three sandbox-function suggestion pills.
• Click "Calculator (calls evaluateExpression)" — a calculator mounts in a sandboxed iframe. Press a few digits and = — the display shows the evaluated result.
• Click "Ping the host (calls notifyHost)" — a card mounts with a "Say hi to the host" button. Clicking it shows a host-returned confirmation with a receivedAt timestamp.

Regression

• Check the browser console for [open-gen-ui/advanced] log lines proving the sandbox -> host round trip fired.

Known gaps

• Same Strands backend as the minimal variant.
