Adversarial Agentic Validation: A Multi-Agent Framework for Autonomous Code Verification

The marginal cost of producing source code has fallen by orders of magnitude; the marginal cost of verifying it has not. Contemporary generative development, colloquially "vibe coding", decouples authorship from comprehension and saturates human review capacity. We propose Adversarial Agentic Validation (AAV), a verification architecture organised around four interlocking pillars: (i) Asymmetric adversarial pairs, (ii) Invariant-driven fuzzing, (iii) Immutable audit trails, and (iv) Deterministic AST barriers. We formalise the workflow, bound its epistemic claim, and discuss the practical friction points of implementing autonomous code verification in production infrastructures.
