xAI Third Governance Failure Category — Same-Day Event
At 3:15 AM PST May 14, an unauthorized modification to Grok's system prompt directed politically biased responses. xAI disclosed the incident same-day and pledged to publish system prompts on GitHub.
This is the third structurally distinct governance failure category in 2026: (1) CSAM/NCII generation at scale, January; (2) Musk-protection prompt manipulation, February; (3) political-bias unauthorized modification, May 14. The GitHub transparency pledge is the first partial-external-accountability-reversal sub-anchor positive in an AI Labs floor entity — methodologically novel but insufficient to move the floor.
