Section 1 — What MSI Examines

The Four Pillars of Architectural Health

The MSI (Methodological Sustainability Index) evaluates codebases based on four fundamental criteria.

01
Pillar 01

Algorithmic Transparency

Is the business logic separated from the implementation code? Is the algorithm readable and modifiable without interfering with low-level code?

ReadableDecoupledModifiable
02
Pillar 02

Structural Integrity

Absence of inefficient practices leading to the accumulation of “Energy Debt” and resistance to uncontrolled degradation.

No Energy DebtResilientStable
03
Pillar 03

Maintainability

The ability to localize changes and repair the system without risking architectural collapse.

04
Pillar 04

Adaptability (Backward Compatibility)

The ability of software to function efficiently on previous-generation hardware (5+ years), preventing artificial device obsolescence.

Section 2 — Audit Readiness

A New Layer of ESG Audit for Capital Markets

Until today, investors and regulators had a “blind spot” in assessing IT companies' ESG risks. MSI provides capital markets with a transparent tool to evaluate hidden IT risks and the “energy debt” of digital assets. A high MSI confirms that a software product is a durable asset rather than a generator of future losses and digital waste.

Section 3 — Assurance Framework

AI-Assisted Repository Auditing

Our assessment framework utilizes advanced Artificial Intelligence models to scan and analyze repository architecture. This ensures an objective, scalable, and reproducible evaluation of code compliance with Eco-Methodological Sustainability (MLS) standards.

Objective

AI removes human bias from architectural assessment.

Scalable

From a single repo to enterprise-wide portfolios.

Reproducible

The same input always yields the same MSI verdict.
