NEXUS OS v3.0

Enterprise-Grade Multi-Agent Governance Platform
_{Built for production A2A systems with cutting-edge trust, budget, and compliance}

---

Overview

NEXUS OS v3.0 is a production-hardened multi-agent operating system designed for enterprise-level A2A (Agent-to-Agent) deployments. It provides comprehensive governance, trust scoring, token budget management, and audit trails for autonomous agent swarms.

Key Features

• Trust Scoring v2.1 — Lane-scoped Bayesian reputation with non-compensatory harm detection
• TokenGuard — Token budget gates with 429 responses and hard-stop enforcement
• GMR Engine v3.0 — Intelligent model selection with dual-pool (FAST/PREMIUM) routing
• VAP Proof Chain — SHA-256 immutable audit trail with L1+L2 cryptographic verification
• 5-Track Memory — EVENT, TRUST, CAPABILITY, FAILURE_PATTERN, GOVERNANCE tracks
• Execution Paths — HOT/WARM/COLD path routing with SLA enforcement
• Hermes Router — Intent classification and model selection pipeline

Installation

# Clone the repository
git clone https://github.com/specimba/nexusalpha.git
cd nexus-os

# Install dependencies (Python 3.10+)
pip install -e .

# Run diagnostics
python scripts/diagnostic.py

---

Quick Start

from nexus_os.monitoring.token_guard import TokenGuard
from nexus_os.engine.hermes import HermesRouter
from nexus_os.monitoring.trust_scorer import TrustScorer

# Initialize components
token_guard = TokenGuard(budgets={'agent-1': 100000})
router = HermesRouter()
scorer = TrustScorer()

# Check budget
if token_guard.check('agent-1', 5000):
    # Route request through GMR
    result = router.route('agent-1', 'Write authentication function', {})
    print(f"Selected model: {result.selected_model}")

Components

GMR Engine (Genius Model Rotator)

Budget-aware model selection:

Budget	Pool	Example Models
0-100k	FAST	osman-coder (tier-40)
100k-200k	MID	Devstral (tier-70)
200k+	PREMIUM	Devstral 2 123B (tier-86)

Trust Scorer v2.1

Lane-scoped parameters:

Lane	Rcrit	qmin
research	0.7	0.3
audit	0.3	0.7
compliance	0.2	0.7
implementation	0.4	0.4
orchestration	0.4	0.5
general	0.6	0.1

TokenGuard

Budget enforcement:

• Budget OK — Process request, track usage
• Budget Exceeded — Return 429 with X-Token-Remaining header
• Hard Stop — Block at Governor level
