On the Formal Foundation of Boundary 4: A State-Space Proof That Non-Trivial Verification Gates Converge to Trivial Machines Under Volume Saturation

Counts differ because each database indexes a different set of publications. We treat OpenAlex as the canonical count; Google Scholar is not shown (no API, and crawling it violates its ToS).

This paper provides the formal foundation for Boundary 4 of the Instrumentum Vocale verification architecture: the requirement that the human decision at the verification gate must remain a genuine act of judgment. Using Heinz von Foerster’s distinction between trivial and non-trivial machines, the paper models the human verification gate as a state-space system whose output depends on both the input and an evolving internal state. It identifies three conditions under which such a gate degenerates into trivial operation: rate saturation, domain mismatch, and constant-output equilibrium. Article-05.pdf The paper proves that under these conditions the causal relationship between input and judgment collapses, so that the gate may remain procedurally present while becoming epistemically ineffective. It further derives measurable architectural requirements for preserving genuine human verification: volume control, routing by competence, and monitoring for state collapse. The analysis is particularly relevant to LLM-assisted institutional decision-making, where the volume of generated assertion-candidates may exceed human verification capacity by orders of magnitude, turning nominal human review into ritualised approval rather than substantive judgment.
