Personnel: Rosie Campbell at OpenAI (Head of Safety Policy)

Note: The source text is a generic OpenAI website homepage with no personnel directory, staff listings, or biographical information. It contains only product announcements, news articles, research summaries, and business case studies. There is no mention of Rosie Campbell, her role as Head of Safety Policy, her employment dates, or any other personnel details. The source material is simply not relevant to verifying personnel records. This is an 'unverifiable' case because the source does not address the claim at all, rather than contradicting it.
