Auditability Beyond Computation: A Formal Model of Structural Drift and Semantic Stability

This paper introduces a formal model of auditability for systems under structural and semantic drift. Based on classical complexity results (e.g., Håstad’s Switching Lemma for AC⁰ circuits), we define concepts like Drift, Reentry, Audit Lemmas, and SnapScore. 

We present SnapOS: a semantic audit architecture that monitors epistemic coherence, structural degradation, and traceable meaning within formal and computational systems.

Applications include interpretable AI, proof verification, and resilient reasoning frameworks. 

Includes: full LaTeX source, audit licensing model (AuditCore License 1.0), and SnapOperator definitions.

Note: This preprint is also governed by the included AuditCore License 1.0, which specifies structural reuse restrictions, commercial licensing conditions (3.8% clause), and semantic audit requirements. See Appendix A of the PDF for full terms.

This preprint forms part of the foundational framework for the forthcoming SnapDrift Trilogy, which will be published in print (via KDP, GRIN, or traditional publisher).
