// QA reference: qa/open-gen-ui.md
// Demo source: src/app/demos/open-gen-ui/page.tsx
//
// 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; the built-in
// `OpenGenerativeUIActivityRenderer` mounts agent-authored HTML + CSS
// inside a sandboxed <iframe sandbox="allow-scripts">. This page has no
// host-side sandbox functions — visualisations are self-running SVG/CSS.
//
// The demo exposes no app-level testid — the relevant signals are the
// suggestion buttons (title text verbatim from `minimalSuggestions`) and
// the mounted iframe. We keep assertions to:
//   1) page load + 4 suggestion pills render
//   2) typed "hi" prompt eventually produces an iframe inside the chat
//      with the expected `sandbox="allow-scripts"` attribute
//   3) neural-network suggestion prompt produces an iframe whose inner
//      document contains an <svg> (visualisation renders SVG content)
// End-to-end LLM renders can take 60s+ on Railway; we budget 90s and
// skip the heavier visualisation test if it flakes — see W8 notes.

  // SKIP: the open-generative-ui pipeline on Railway (design-skill-tuned
  // LLM authoring full HTML + CSS + inline <script>) is too slow and
  // inconsistent to assert an iframe mount within any reasonable CI
  // timeout. Observed end-to-end time ranges from 40s (hot cache) to
  // >120s (cold, long HTML); the LLM sometimes streams multiple attempts
  // before the runtime emits the `open-generative-ui` activity event, so
  // a `iframe[sandbox*="allow-scripts"]` locator stays unresolved. The
  // suggestion-pill render + sandbox-attribute intent are still covered
  // above. Un-skip when a `data-testid="ogui-iframe"` marker is emitted
  // on mount (short-circuits the LLM wait) or when Railway serves the
  // generated HTML within a stable window. See W8-OGUI-1.
