Ingesting regulatory amendments as Policy Set deltas and verifying gate rule consistency through automated compliance checking
Regulatory environments can change faster than manual compliance workflows can absorb updates. When GDPR, CCPA, or Basel-related requirements shift, enterprises face propagation delays between rule publication and operational enforcement. This paper models regulatory updates as algebraic Policy Set deltas, defines a merge operation `P_{t+1} = P_t + DeltaP` with consistency checks, and presents a verification pipeline that detects conflicts between incoming and existing policy rules before deployment to production gates. Benchmarks over 847 regulatory amendments showed 99.2% consistency-verification accuracy with sub-200ms propagation latency.
Formalizing gate strength as a continuous control variable to minimize the combined cost of false positives, missed detections, and investigation delay in AML compliance pipelines
AML programs face a costly tradeoff between false positives, missed detections, and investigation delay. This paper formalizes AML detection as constrained loss minimization over gate strength `g`, derives gate configurations with Lagrangian methods under BSA/FATF/EU AMLD constraints, and reports that MARIA OS responsibility gates reduced total compliance cost by 47% while maintaining required detection thresholds in evaluated settings. The framework treats gate strength as a continuous control variable rather than a binary switch.
Formal evidence graph construction and matrix-algebraic traceability for reconstructing every financial decision under SOX, Basel III, and MiFID II
Regulatory reconstruction of AI-driven financial decisions is difficult when logs are fragmented, timestamps drift, or causal links are missing. This paper introduces a formal evidence-graph model where each decision is an immutable node in a directed acyclic graph, linked by typed causal edges with cryptographic evidence bundles. We define `TraceCompleteness` as `TC = |reproducible decisions| / |total decisions|` and report `TC >= 0.997` across evaluated SOX, Basel III, and MiFID II audit scenarios.
