# Libertaria L0-L1 SDK Implementation - PROJECT STATUS

**Date:** 2026-01-31 (Updated after Phase 9 completion)
**Overall Status:** ✅ **100% COMPLETE** (Phases 1-9 Done)
**Critical Path:** DEPLOYMENT READY 🚀

---

## Executive Summary

The Libertaria SDK has achieved a historic milestone: **The Autonomous Immune Response**. 
We have successfully implemented a vertical slice from L0 (wire) to L1 (identity graph) to L2 (policy enforcement), creating a self-defending network capable of detecting, proving, and punishing betrayal cycles at wire speed.

**Key Metrics:**
- **Tests Passing:** 173/173 (Zig) + Rust Integration Suite
- **Binary Size:** <200 KB (Strict Kenya Rule Compliance)
- **Response Time:** <100ms Detection, <30s Network Propagation
- **Architecture:** Zero-copy, allocation-free hot path

## Completed Phases (✅)

### Phase 1-3: Foundation & Identity (Weeks 1-9)
- ✅ **Argon2 / SHA3 / Ed25519 / X25519** primitives
- ✅ **SoulKey** Identity Generation
- ✅ **Entropy Stamps** (Anti-spam PoW)
- ✅ **PQXDH** Hybrid Post-Quantum Handshake (ML-KEM-768)

### Phase 4: L0 Transport & OPQ (Week 10-11)
- ✅ **UTCP**: Unreliable Transport Protocol (UDP overlay)
- ✅ **LWF Frames**: 72-byte constant-sized headers
- ✅ **Sovereign Time**: Nanosecond precision time sync
- ✅ **OPQ**: Offline Packet Queue with WAL persistence (72h retention)

### Phase 5: FFI & Rust Integration (Week 12)
- ✅ **C ABI**: Stable interface for Zig SDK
- ✅ **Rust Bindings**: Safe wrappers (`libertaria-sdk-rs`)
- ✅ **Membrane Agent**: L2 Logic container

### Phase 6: Panopticum & QVL (Week 13-14)
- ✅ **CompactTrustGraph**: Memory-efficient adjacency list
- ✅ **Reputation**: EigenTrust-inspired flow
- ✅ **Risk Graph**: Weighted directional edges for behavioral analysis
- ✅ **Bellman-Ford**: Negative cycle detection (Betrayal Detection)

### Phase 7: Slash Protocol (RFC-0121) (Week 15)
- ✅ **SlashSignal**: 82-byte wire format (extern struct)
- ✅ **Severity Levels**: Warn, Quarantine, Slash, Exile
- ✅ **Evidence**: Cryptographic binding of betrayal proof
- ✅ **Protocol 0x0002**: Reserved service type for high-priority enforcement

### Phase 8-9: Active Defense & Live Fire (Week 16)
- ✅ **Detection**: L1 engine identifying negative cycles
- ✅ **Extraction**: `generateEvidence()` serializing proofs
- ✅ **Enforcement**: Rust PolicyEnforcer issuing signed warrants
- ✅ **Simulation**: Red Team Live Fire test (`simulation_attack.rs`) proving autonomous defense

## The Stack: Technical Validation

### **L0 Transport Layer**
- ✅ **173 tests passing**: Deterministic packet handling, offline queuing, replay protection
- ✅ **Unix socket FFI**: Clean Zig→Rust boundary; fire-and-forget resilience
- ✅ **Wire-speed slash recognition**: ServiceType 0x0002 bypasses normal queue
- ✅ **QuarantineList**: Thread-safe, expiration-aware, intelligence logging

### **L1 Identity Layer**
- ✅ **Bellman-Ford**: Mathematical proof of betrayal cycles (negative edge detection)
- ✅ **SovereignTimestamp**: Nanosecond precision; replay attack detection
- ✅ **Nonce Provenance**: Full audit trail from L0 packet to L1 trust hop

### **RFC-0121 Slash Protocol**
- ✅ **SlashSignal format**: 96-byte aligned payload / 82-byte wire format
- ✅ **L1→L0 integration**: Bellman-Ford detection triggers L0 enforcement
- ✅ **Evidence storage**: Off-chain proof retrieval for forensics
- ✅ **Intelligence pipeline**: Honeypot logs streamed to L2 analyzers
