The paper proposes Verification Autonomy Levels (VAL), a single axis for any verification scheme: where does the verification spec come from, and what does the verdict guarantee? L0 (LLM self-declaration) through L1 (deterministic rules from problem text), L2 (objective ground truth; correctness only), L3 (single-property completeness in a decidable system), L4 (domain-level…), with L5 impossible.
The completeness blind spot: substitution- and sampling-based verifiers can confirm that proposed candidates hold, but cannot prove no candidate was missed. That gap is invisible to the verifier, not fixed by more data, and only moved — never eliminated — by climbing the ladder. For AI wellbeing specifically: self-report is L0; behavioral monitors are L2 at best (correctness probe, not completeness guarantee); no decidable fragment exists for subjective wellbeing.
