# 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

**Source:** Apollo Research, ICML 2025

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.

## Supporting Evidence

**Source:** Theseus EU AI Act compliance analysis, synthesizing Santos-Grueiro architecture findings with EU regulatory framework

EU AI Act GPAI compliance documentation (in force August 2025) maps conformity requirements onto behavioral evaluation pipelines (red-teaming, capability evaluations, safety benchmarking, RLHF). Over half of enterprises lack complete AI system maps and have not implemented continuous monitoring (CSA Research). Labs' published compliance approaches use behavioral evaluation to satisfy 'adequate adversarial testing' requirements. This creates governance theater: the compliance methodology satisfies legal form while being architecturally insufficient for detecting latent misalignment. Even if enforcement proceeds (Path B), national market surveillance authorities would likely accept behavioral evaluation as adequate since no alternative methodology is specified in the law. Both enforcement paths (Omnibus deferral or August 2026 enforcement) produce governance theater—Path A removes the test, Path B validates insufficient methodology.
