The source text is a homepage and informational content from what is now called Coefficient Giving (formerly Open Philanthropy). While it confirms the organization exists and was previously named Open Philanthropy, it contains no information about Holden Karnofsky, his position as Co-CEO, or the dates of his employment. The source does not address any of the specific personnel record claims. This is a case of wrong source relevance — the source discusses the organization itself but not the specific personnel claim being verified.
