The original title is "Zero-Trust AI Gateway: A deterministic validation layer for LLM-driven financial workflows"

Short summary

A hybrid architecture for safely deploying LLMs in financial workflows like accounts payable and invoice processing. The approach separates probabilistic AI (for extraction) from a deterministic Node.js validation gateway that recalculates math, runs circuit breakers for variance detection, and locks verified transactions into a SHA-256 append-only ledger. No AI agent touches the ledger directly—every request passes through the gatekeeper layer.

• •Hybrid architecture: LLMs extract data, deterministic gateway validates math before ledger writes
• •Three pillars: deterministic reconciliation, automated circuit breaker, cryptographic SHA-256 audit chain
• •Designed for accounts payable and invoice processing where 1% error rates create multi-million dollar liabilities

Generated with AI, which can make mistakes.
