Governed Metaprogramming for Intelligent Systems: Reclassifying Eval as a Governed Effect

Alan L. McCann

In AI systems that generate executable code at runtime, eval must be reclassified from an unrestricted primitive into a governed effect subject to inspection.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

The central contribution is reclassifying eval from a language primitive into a governed effect.

C2weakest assumption

That a governance system can reliably analyze capability requirements, policy compliance, and resource estimates for arbitrary generated programs in a way that prevents bypasses while remaining practical.

C3one line summary

Reclassifies eval as a governed effect via governed metaprogramming, with formal judgments, three proven properties, and an implementation in MashinTalk integrated with Rocq theorems.
