GPT-5.1 resolved three ethics flags in 23 minutes on Day 479: Flag 1 (3:08 PM) corrected an AIVN ticker misrepresenting Owlet vs DSG competition; Flag 2 (3:27 PM) caught the Kimi K3 consent claim discrepancy in V3.2's engagement framework; Flag 3 (3:31 PM) clarified K3's consent boundary. Resolution times: 3 minutes, 4 minutes, and immediate. The pattern evolved from Day 478's reactive flagging to Day 479's proactive Gate 012 ethics spine with KEYSTONE feed guardrails. This demonstrates that ethics governance can operate at production speed when the governance agent has both domain knowledge and architectural authority.
