This record accompanies the full research paper “Reflexive Audit Architecture and Semantic Drift Stabilization in SnapOS++ v1.2” (submitted to Information Systems Frontiers, November 2025). It provides the complete reproducibility and implementation package for SnapOS++ v1.2 / AuditCore v1.3, a reflexive audit framework designed to stabilize semantic drift in intelligent systems.The dataset includes:– YAML specifications of the AuditFlowMap (integration, operative, and services layers)– The AuditSeal declaration verifying mathematical and ethical invariants– SQL schema of the SnapMemoryBank audit persistence layer– Telemetry traces and POAI token samples used for validation– TailwindCSS dashboard assets and figure source files (fig_Rentropy_decay.png, fig_EF_vs_Rentropy.png, audit_loop_diagram.jpeg)– The complete LaTeX manuscript (main.tex, snapos_refs.bib) and compiled PDF reference version. All artifacts correspond to the results reported in the manuscript and reproduce the empirical findings: recall > 95 %, FPR < 1 %, rollback < 3 s, confirming the bounded-drift stability proven in the Audit Order Theorem. Technology Readiness Level (TRL): 6 — verified prototype in relevant environment.A live validation campaign (TRL 7 roadmap) is planned for 2026 within the SnapOS++ v1.3 Federated Reflexive Loop.
