What is Janus

Overview

Janus is a governance core for systems where humans, software, and AI participate in decision processes.

Janus does not execute business logic. It governs how system evolution is evaluated, recorded, and reconstructed.

The problem

Most systems record what happened. Very few systems record what should have happened but did not.

This becomes critical in AI-assisted environments, where omissions and missing validations can create risk.

The Janus approach

Janus evaluates governance conditions rather than application logic. Key ideas include the evidence model (E+ / E−), governance events, human authority, the audit writer boundary, and deterministic rebuild.

activity → evaluation → governance event → audit log → rebuildable state

Governance flow

The governance flow shows the conceptual boundary: governance sits above execution and ensures evidence, auditability, and rebuildable state.
