# Libertaria SDK

**The Core Protocol Stack for Libertaria Applications**

**Version:** 1.0.0-beta ("Shield")
**License:** TBD
**Status:** 🛡️ **AUTONOMOUS IMMUNE RESPONSE: OPERATIONAL** (100% Complete)

## 🚀 The Autonomous Immune System

Libertaria SDK is not just a protocol; it is a **self-defending nervous system**.
We have achieved the **Vertical Active Defense Loop**:

1.  **Detect**: L1 QVL Engine uses Bellman-Ford to mathematically prove betrayal cycles (sybil rings).
2.  **Prove**: The engine serializes the cycle into a cryptographic **Evidence Blob**.
3.  **Enforce**: The L2 Policy Agent issues a **SlashSignal** containing the Evidence Hash.
4.  **Isolate**: The L0 Transport Layer reads the signal at wire speed and **Quarantines** the traitor.

This happens autonomously, in milliseconds, without human intervention or central consensus.

## The Stack

### **L0 Transport Layer (`l0-transport/`)**
- **Protocol**: LWF (Libertaria Wire Frame) RFC-0000
- **Features**: 
  - UTCP (Unreliable Transport)
  - OPQ (Offline Packet Queue) with 72h WAL
  - **QuarantineList** & Honeypot Mode
  - ServiceType 0x0002 (Slash) Prioritization

### **L1 Identity Layer (`l1-identity/`)**
- **Protocol**: SoulKey RFC-0250 + QVL RFC-0120
- **Features**:
  - **CompactTrustGraph**: High-performance trust storage
  - **RiskGraph**: Behavioral analysis
  - **Bellman-Ford**: Negative Cycle Detection
  - **Slash Protocol**: RFC-0121 Evidence-based punishment

### **L2 Membrane Agent (`membrane-agent/`)**
- **Language**: Rust
- **Role**: Policy Enforcement & Strategic Logic
- **Capability**: Auto-negotiates PQXDH, manages Prekeys, executes Active Defense.

## Quick Start

### Build L1 Engine (Zig)
```bash
zig build
```

### Run Active Defense Simulation (Rust)
```bash
cd membrane-agent
cargo test --test simulation_attack -- --nocapture
```
*Watch the system detect a traitor and issue a death warrant in real-time.*
