NoteQUA-650 retro-scan: The source is a biography of Sam Altman as a person, not about Y Combinator as an organization. Per QUA-648, a source about a person's role at an organization is a MISMATCH when the claim's subject is the organization itself. The claim requires a source about Y Combinator, not about Sam Altman.
