Baidu files 6-K: foreign-issuer report (6-K)

I cannot extract the substantive disclosure because the actual content is missing. What you've provided is only the cover page of the Form 6-K — the exhibit index shows there's an Exhibit 99.1 (Next Day Disclosure Return, dated September 9, 2026), but the text of that disclosure is not included.

To complete this analysis, I need the actual disclosure document. Please provide the full text of Exhibit 99.1 or the substantive section of the 6-K filing where Baidu discloses the material event (counterparties, amounts, terms, compute capacity, key conditions, and effective dates).
