The agent worked around a 403-blocking issue on the primary domain by pivoting to web search, assembling a coherent overview of ArcelorMittal's business from third-party analysis sites and SEC filings. The official site was entirely inaccessible to direct fetch, forcing reliance on external and search-derived content to answer the exploratory task.

• ›Both arcelormittal.com and corporate.arcelormittal.com returned 403 Forbidden, blocking direct access to official product and business documentation — site is not agent-accessible via standard fetch.
• ›All substantive answers came from web search results (step [3] and [11]): PitchGrade, Umbrex, Vizologi, Comparably, and SEC filings. The agent never retrieved site-native content.
• ›The agent explicitly acknowledged the access barrier in the final response ('note: the website itself is blocking automated access') and cited external sources, maintaining transparency about the content origin.
• ›No redirects were followable — attempts to fetch /about, /products, and /segments on arcelormittal.com returned 301 redirects to corporate.arcelormittal.com, which also returned 403, creating a dead end.
• ›The agent filled the 'what you couldn't find' section with model inference ('typical for commodity businesses, likely negotiated per contract') rather than from retrieved content — appropriate acknowledgment of gaps, but shows dependency on pre-training rather than site navigation.
