Proof Language - AI-Verified Programming Language

🎯 What is Proof Language?

Proof is a next-generation programming language that combines natural language intent, mathematical verification, and automated deployment to create trustworthy, verifiable software systems.

The Vision:

Human Intent (자연어)
    ↓
Intent Parser (자연어 이해)
    ↓
Proof Code (검증 가능한 형태)
    ↓
Z3 SMT Solver (수학적 증명)
    ↓
Code Generator (FreeLang)
    ↓
Multi-Language Binary (C/Python/Go/Rust)
    ↓
Blue-Green Deployment (무중단 배포)
    ↓
Immutable Recording (Gogs 증명 체인)
