Personnel: Aidan Gomez at Google Brain (Research Intern)

NoteThe source confirms all key fields of the record: (1) person is Aidan Gomez ✓, (2) org is Google Brain ✓, (3) role includes 'intern at Google Brain' in 2017 ✓, (4) startDate 2017 is confirmed ('In 2017, as a 20 year-old intern at Google Brain') ✓, (5) endDate 2017 is consistent with the source stating he was an intern in 2017 and later worked as a researcher at Google Brain as a PhD student (implying the internship ended in 2017) ✓. The source does not explicitly state an end date of 2017, but the narrative structure (intern in 2017, then PhD student researcher later) supports this inference. No contradictions detected.

NoteQUA-650 retro-scan: The source is a biography of Aidan Gomez as a person, not about Google Brain as an organization. While the source mentions Gomez's work at Google Brain, the primary subject is Aidan Gomez himself, not Google Brain. Per QUA-648, a person's biography is a mismatch when the claim subject is an organization.
