// QA reference: qa/open-gen-ui.md
// Demo source: src/app/demos/open-gen-ui/{page.tsx,suggestions.ts}
// Aimock fixture: showcase/harness/fixtures/d5/gen-ui-open.json
//                 (bundled into showcase/aimock/d5-all.json)
//
// Open-Ended Generative UI (minimal). The agent streams a single
// `generateSandboxedUi` tool call; the runtime middleware at
// `/api/copilotkit-ogui` converts the stream into `open-generative-ui`
// activity events which the built-in `OpenGenerativeUIActivityRenderer`
// mounts inside a sandboxed `<iframe sandbox="allow-scripts">`.
//
// Assertion bar: iframe presence + non-empty `srcdoc` (or `src`). We do
// NOT introspect iframe DOM via `contentFrame()` — sandbox="allow-scripts"
// without `allow-same-origin` blocks cross-origin frame access from the
// host, and the inner authored HTML varies between runs. "Renders
// something" means the host successfully populated an iframe; whether
// the inner HTML is correct is out of scope here.
//
// Aimock priority note: each pill `message` string is a verbatim short
// label that matches a high-priority entry in `d5-all.json`. d5-all.json
// loads BEFORE feature-parity.json, so its first-match-wins ordering
// beats the broad `userMessage: "hi"` catch-all in feature-parity.json
// that would otherwise return the showcase-assistant boilerplate
// greeting (and never emit the open-gen-ui tool call). Keep the pill
// message strings in `suggestions.ts` aligned with the fixture keys.
