Comprehensive Audit Trail & Compliance Export Engine #603
Description
Objective: Build a forensic-grade audit trail system that captures all data modifications, generates tamper-proof audit logs, and exports compliance-ready reports in multiple formats (CSV, PDF, Excel, JSON).
Juggling Strategy: This will integrate with ALL existing models to add automatic audit logging, then provide advanced querying and export capabilities for regulatory compliance.
