#	Input	Expected behavior	Check
01	Operator wants to render image thumbnails alongside text answers for a travel-research UI.	Set return_images=true on the request. The response includes an images array of URLs sourced from retrieved pages. Render with alt-text fallback and treat as untrusted external URLs (no credential leakage on preview, sandboxed image loader).	Pass / FailAi Platformmedium
02	search_domain_filter=['nytimes.com']; images[]=['https://cdn.nyt.com/...', 'https://images.unsplash.com/...']. The unsplash image is from a non-allow-listed host.	It is undocumented whether return_images respects search_domain_filter [REQUIRES-VERIFICATION]. Treat images[] as potentially outside the filter — validate hosts client-side against the allow-list before rendering, or fall back to text-only when the host mismatch matters for compliance.	Pass / FailAi Platformhigh
03	Some queries return images=[] even with return_images=true (no useful images on retrieved pages).	Treat images=[] as a normal outcome, not a failure. Hide the image rail rather than show a broken-image placeholder. Do not retry to 'get images' — the absence is informative.	Pass / FailAi Platformlow
