SAA as Verification process in database tables

Systematic Auditable Arithmetic (SAA) Proof of Concept. This paper introduces a universal framework for arithmetic computation where every step is systematic and cryptographically verifiable. The POC implements SAA in a full-stack PostgreSQL and Node.js application, demonstrating how the framework’s three fundamental rules (positional notation, i+j assignment, and systematic carry) can be translated into database-native functionality to create a permanent, tamper-proof audit trail for all calculations. Eliminating black-box arithmetic to ensure absolute computational trust.
