Unified Event-Sourced CQRS Architecture for Continuous Compliance Monitoring and Automated Regulatory Reporting

Abstract	Compliance audits in distributed systems have historically been reactive, relying on periodic sampling and manual correlation of disparate logs. This paper presents a unified event-sourced Command Query Responsibility Segregation (CQRS) architecture that streams both command-side state transitions and query-side access events into a dedicated compliance engine for real-time evaluation. A canonical event model, standardized event-to-rule mapping, and deterministic replay semantics are specified to transform auditability into a continuous capability. The architecture integrates immutable event storage, low latency streaming computation, and declarative policy evaluation to enable automated regulatory reporting and verifiable evidence generation. Design considerations, subsystem interactions, evaluation metrics, and operational constraints are detailed, drawing on recent advances in event-driven compliance monitoring and distributed system observability.
Keywords	Event sourcing, CQRS, compliance auditing, streaming policy evaluation, regulatory reporting, immutable logs, provenance, deterministic replay, data governance.
