Overview

NEXUS is the world's first enterprise-grade AI agent orchestration platform that treats compliance as a feature, not an afterthought. Built for regulated industries that need AI agents but cannot afford compliance breaches.

Breakthrough: Defense-in-Depth Compliance

BASTION - The world's first kernel-level AI compliance enforcement. While competitors check compliance in Python/JavaScript (application layer), BASTION makes violations mathematically impossible by blocking syscalls at the Linux kernel level using seccomp-BPF.

BASTION-SC - The world's first smart contract DeFi protocol with full 4-layer compliance integration. Extends compliance from Python and kernel to blockchain, with immutable audit trails on IPFS and Arweave.

Infrastructure & Determinism

NEXUS enforces a "Lab-in-a-Box" philosophy using strict Infrastructure-as-Code principles.

The Hermetic Stack

We utilize Nix Flakes to guarantee bit-perfect reproducibility across all development and CI environments. This eliminates "it works on my machine" issues by pinning the entire dependency graph, from the system glibc to the Python interpreter.

• Base: nixos-unstable (Pinned via flake.lock)
• Runtime: Python 3.13 + uv for ultra-fast package resolution
• Compute: CUDA-ready environment with ray distributed backend
• Orchestration: temporal + mlflow + postgres defined in docker-compose.yml

Developer Experience (DevX)

The environment bootstraps instantly via nix develop, providing a shell with all tools pre-configured:

# 1. Enter the hermetic environment
nix develop

# 2. Spin up the infrastructure
just infra-up

# 3. Run the compliance suite
just test-sentinel

No manual installation of CUDA, Postgres, or Python is required. Everything is declarative.

The 6 Pillars

Quick Start

Installation

# Clone repository
git clone https://github.com/kernelcore/neutron.git
cd neutron

# Install dependencies
pip install -e .

# Run tests
python scripts/run_all_tests.py

Basic Usage

from neutron.orchestration import AgentSwarm, Task, ConsensusStrategy
from neutron.reasoning import ExplanationType

# Create multi-agent swarm
swarm = AgentSwarm(agents=[agent_a, agent_b, agent_c])

# Execute with automatic explanation
result = await swarm.execute(
    Task(type="loan_decision", input={"credit_score": 750}),
    generate_explanation=True,
    explanation_type=ExplanationType.CHAIN_OF_THOUGHT
)

# View transparent explanation
print(result.explanation.to_human_readable())

Compliance Validation

from neutron.compliance import validate_with_gdpr, validate_ai_act_compliance
from neutron.compliance.sentinel import AgentOutput

# Create AI output
output = AgentOutput(
    content="Loan approved",
    metadata={
        "use_case": "credit_scoring",
        "ai_disclosure": True,
        "human_oversight_enabled": True,
        # ... compliance metadata
    }
)

# Validate compliance automatically
gdpr_results = validate_with_gdpr(output)
ai_act_results = validate_ai_act_compliance(output)

# All frameworks validated ✓

Kernel-Level Enforcement (BASTION)

from neutron.compliance.auditors.lgpd_kernel import (
    lgpd_art7_consent_policy,
    grant_lgpd_consent,
    revoke_lgpd_consent
)

# Grant LGPD consent for customer
grant_lgpd_consent("customer_123")

# Access personal data under kernel enforcement
with lgpd_art7_consent_policy.enforce():
    # Syscalls 'open' and 'read' are now protected by Linux kernel
    # Without CAP_CONSENT_TOKEN → kernel returns EACCES
    # Physically impossible to bypass - enforced at syscall level
    data = read_customer_data("customer_123")

# Revoke consent - now ANY attempt to access data is blocked by kernel
revoke_lgpd_consent("customer_123")

# Result: Compliance violations mathematically impossible 🛡️

Compliance

NEXUS is the only platform with built-in compliance for all three major frameworks across 4 enforcement layers:

Framework	Coverage	Articles	Tests	Enforcement
LGPD (Brazil)	✅ Complete	Art. 7, 16, 18, 20, 46	135+	All 4 Layers 🚀
GDPR (EU)	✅ Complete	Art. 15, 17, 22	45+	Application
EU AI Act	✅ Complete	Art. 5, 13, 14 + Risk	60+	Application

Automatic Validation: Every build validates all three frameworks

Breakthrough: LGPD compliance enforced at 4 layers:

1. Application: Python validation (SENTINEL)
2. Kernel: seccomp-BPF syscall filtering (BASTION)
3. Smart Contracts: Solidity modifiers (BASTION-SC) ← World's First DeFi Integration
4. Decentralized Audit: IPFS + Arweave permanent logs ← 200+ year permanence

Result: Compliance violations mathematically impossible at every layer
