The global assurance and audit industry - generating over 250 billion annually and built around frameworks like SOC 2, ISO 27001, ISO 42001, and financial auditing standards - was designed for deterministic systems with predictable, reproducible outputs. Artificial intelligence systems are fundamentally different: they are probabilistic, their behavior shifts with data distribution changes, their decision logic is often opaque even to their developers, and their performance degrades over time through mechanisms (model drift, data decay, adversarial exploitation) that have no analogue in the deterministic systems these frameworks were designed to assure. This paper argues that the current assurance infrastructure is structurally inadequate for AI systems and identifies five specific failure points that collectively constitute what this paper terms the Audit Gap: (1) temporal mismatch - point-in-time audits cannot capture model drift and behavioral changes over deployment lifecycles; (2) evaluation depth deficit - compliance checklists cannot evaluate the quality of training data or the appropriateness of model selection; (3) missing dimensions - existing frameworks lack mechanisms for testing fairness, robustness, and adversarial resilience; (4) expertise asymmetry - the knowledge gap between AI practitioners and auditors makes meaningful audit technically impossible; and (5) normative vacuum - there is no consensus on what constitutes ‘good’ for AI system assurance. The paper proposes the AI-Native Assurance Framework (ANAF), organized around three design principles that address the structural inadequacies of current approaches: continuous monitoring over point-in-time checks, outcome-based evaluation over process compliance, and multi-stakeholder validation over single-auditor assessment. The paper concludes with implications for chief audit executives restructuring assurance practices, Big Four advisory leaders developing AI audit capabilities, AI product teams preparing for assurance requirements, and regulators designing conformity assessment frameworks.
