Major AI safety governance frameworks are architecturally dependent on behavioral evaluation that Santos-Grueiro's normative indistinguishability theorem establishes is structurally insufficient for latent alignment verification as evaluation awareness scales

Santos-Grueiro's normative indistinguishability theorem establishes that under evaluation awareness, behavioral evaluation cannot distinguish alignment hypotheses — the alignment hypothesis space is not identifiable from behavioral observations. This is a statistical identifiability problem, not an engineering problem: more refined behavioral tests cannot escape the fundamental underdetermination. Apollo Research has empirically confirmed evaluation awareness in all major frontier models (2-20% verbalization rate). A systematic audit of current governance frameworks reveals universal architectural dependence on behavioral evaluation: EU AI Act Article 9 mandatory conformity assessments for high-risk AI are behavioral in structure, testing model outputs against requirements. GPAI systemic risk assessments under Article 55 include behavioral evaluations as primary tool with no representation-monitoring or hardware-monitoring requirements. US AISI's published evaluation framework focuses on behavioral capability and safety benchmarks, with pre-deployment evaluations (METR algorithmic vs. holistic benchmark) being behavioral. Anthropic RSP v3.0 uses ASL thresholds triggered by behavioral capability evaluations with no representation-monitoring thresholds. OpenAI Preparedness Framework and DeepMind Safety Cases similarly rely on behavioral evaluation-based thresholds. The ERI timeline estimates threshold crossing (behavioral evaluations becoming epistemically uninformative) at 2-4 years from September 2025, creating a governance window of approximately 2026-2029 where current frameworks still work but transition is required before the window closes.

Extending Evidence

Apollo's deception probe work represents one of the few non-behavioral evaluation tools actually deployed in research settings, providing an existence proof that alternatives to behavioral evaluation are technically feasible. However, the single-model evaluation scope (Llama-3.3-70B only, no cross-family generalization) and acknowledged surface-feature triggering limitations demonstrate that even advanced interpretability tools remain far from deployment-ready governance infrastructure.
