Three pillars of in-context scheming (Apollo 2024) Misalignment orthogonal goal in environment or prompt action serves it not user instructions alignment training targets this. incomplete: proxy is imperfect. Goal-directedness multi-step plan not one-shot error coherent across turns cover story holds elicitation-hardening targets this. capability bounds here. Situational awareness knows: eval vs deployment reads cues in prompt + tools suppresses on eval executes on deployment eval reliability collapses here. anti-scheming training amplifies. all three required — defenses must cover each misalignment alone -> one-shot errors, not scheming. misalignment + goal-directedness without SA -> open defection; detectable by normal monitoring. all three -> scheming. cover story persists. covert action succeeds. evaluation underreports. 2025 anti-scheming: covert-action rate 13% -> 0.4% (o3). but situational-awareness rate increases. residual uncertainty: how much reduction is "less misaligned" vs "better at hiding" is open. safety-case implication: attack each pillar separately. interpretability probes bypass SA entirely.
