Machine Economy Index (MEI) and Legal Rail Readiness Score (LRRS): Methodology Documentation

Methodology documentation for the Machine Economy Index (MEI) and its legal component, the Legal Rail Readiness Score (LRRS), methodology version 1.3 (20 October 2026). The record contains the conceptual and mathematical specification of the index framework, inclusion criteria, normalization bounds methodology, legal-coverage scoring rules, and versioning protocol. The MEI tracks machine-economy activity across payments, physical infrastructure, and legal readiness, plus a macro demand component, combined with a geometric mean. The LRRS measures GDP-weighted legal coverage across 48 jurisdictions and five categories. The public methodology overview is available at https://machineeconomy.ai/methodology.
