Do not guess page content. Suggest the user verify the URL and try again. | | Page requires authentication (401/403) | Report that the page is behind authentication. Suggest the user provide the rendered HTML directly or a publicly accessible URL. | | JavaScript-rendered content (empty body in HTML) | Note that key content may be rendered client-side. Analyze the available HTML and flag that results may be incomplete. Suggest using a browser-rendered snapshot if available. |
