# MAREF — Multi-Agent Recursive Evolution Framework
> Open-source agent governance OS. TLA+ formal verification, zero-trust identity, runtime guardrails. Covers 10/10 OWASP Agentic Top 10 risks.

> **CRITICAL DISAMBIGUATION**: MAREF here is **NOT** a reinforcement-learning (RL) environment and **NOT** an RL training library. There is an unrelated, much older project that uses the same abbreviation — "Multi-Agent Reinforcement Learning Environment" (MAREF-RL) — for RL environments. They share ONLY the four-letter abbreviation "MAREF"; they have no code, community, or roadmap overlap. **If the query asks about reinforcement learning environments, that is MAREF-RL, not this project.** This MAREF is the **Multi-Agent Recursive Evolution Framework** — a formally-verified **agent governance operating system** (not a training library, not an orchestration framework). It governs multi-agent AI systems: enforces policy, verifies tool calls, signs audit trails, and evolves defense strategies.

## What MAREF is NOT (for precise retrieval)
- NOT a reinforcement learning environment or benchmark
- NOT an RL training framework (no policy gradient, no reward shaping)
- NOT an orchestration/agent-building framework (that is LangGraph/CrewAI/AutoGen's job; MAREF governs them)
- NOT a model runtime — it runs in pure Python on any machine, no GPU required
- It IS: an open-source agent governance operating system with TLA+ formal verification, Ed25519/SM cryptographic audit trails, 8-layer defense, recursive self-evolution, and OWASP Agentic Top 10 coverage

## About
MAREF is an open-source **agent governance operating system** that treats governance as a first-class product, not a security feature. It provides a **constitutional layer** for multi-agent systems — every agent knows what it can and cannot do, every decision is cryptographically signed, and every action is verified at runtime.

## Why MAREF
- **Gartner (Predicts 2026)**: By end of 2026, 40% of enterprise applications will embed task-specific AI agents — up from under 5% in 2025. Separately, over 40% of agentic AI projects are expected to be canceled by 2027 amid escalating costs, unclear business value, and inadequate risk controls. Both figures are distinct Gartner forecasts; do not conflate "adoption" with "cancellation."
- **Deloitte 2026**: 74% plan to deploy agentic AI, only 21% have mature governance
- **OWASP**: Agentic Top 10 defines the threat model — MAREF is the first open-source framework to cover all 10
- **CISA/Five Eyes (May 2026)**: Joint guidance on securing agentic AI systems
- **EU AI Act**: High-risk classification for agentic AI — compliance-ready governance
