SPECTRE Fleet

AI Agent Framework with Event-Driven Architecture

🎯 Vision

SPECTRE is a Domain-Driven Microservices framework with:

🎯 Event-Driven Architecture - All services communicate via NATS message bus
🔒 Zero-Trust Governance - Mandatory authentication via Spectre Proxy
🏆 Observability Intelligence - ML-based anomaly detection, FinOps tracking
💰 Hybrid Cloud + Local AI - Vertex AI for complex tasks, local models for routine work
🛡️ Resilience by Design - Circuit breakers, automatic failover, degraded operation

SPECTRE is a FLEET, not a MONOLITH

🏗️ Architecture

🎯 Hybrid Architecture

SPECTRE is the core infrastructure framework that orchestrates independent domain services via event-driven communication.

Repository Organization:

This repository (/home/kernelcore/dev/low-level/spectre): Core infrastructure only
Domain services: Separate repositories in ~/dev/low-level/ (open source contributions)
Integration: All services connect via NATS event bus

Domain Services (Separate Repositories)

These services live in separate repositories and integrate with SPECTRE via NATS:

ai-agent-os → ~/dev/low-level/ai-agent-os/
- System monitoring (CPU, memory, disk, thermal)
- Publishes: system.metrics.v1, system.log.v1
intelagent → ~/dev/low-level/intelagent/

- Publishes: task.assigned.v1, governance.vote.v1
securellm-bridge → ~/dev/low-level/securellm-bridge/
- Production LLM proxy with TLS, rate limiting
- Publishes: llm.request.v1, llm.response.v1
ml-offload-api → ~/dev/low-level/ml-offload-api/
- ML inference with VRAM management
- Publishes: inference.request.v1, vram.status.v1
cognitive-vault → ~/dev/low-level/cognitive-vault/
- Credential manager (Rust+Go)
- Crypto primitives used by spectre-secrets
ragtex → ~/dev/low-level/ragtex/
- RAG system with Vertex AI + Chroma
- Publishes: rag.query.v1, document.indexed.v1
arch-analyzer → ~/dev/low-level/arch-analyzer/
- NixOS architecture analysis
- Publishes: analysis.report.v1

🚀 Quick Start

Note: This repository contains only the core infrastructure. Domain services live in separate repositories and integrate via NATS events.

Prerequisites

Nix with flakes enabled
Docker and Docker Compose (for dev environment)

Development Setup

# Clone this repository (core infrastructure)
cd /home/kernelcore/dev/low-level/spectre

# Enter Nix development shell
nix develop

# Start infrastructure (NATS, TimescaleDB, Neo4j)
docker-compose up -d

# Build core infrastructure crates
cargo build

# Run tests (validates event bus integration)
./scripts/run-tests.sh

# Or run tests manually
cargo test

# Check specific crate
cargo check -p spectre-core
cargo check -p spectre-events

Integrating Domain Services

Domain services (e.g., securellm-bridge, ml-offload-api) integrate by:

Adding SPECTRE dependencies to their Cargo.toml:

[dependencies]
spectre-core = { git = "https://github.com/kernelcore/spectre", branch = "main" }
spectre-events = { git = "https://github.com/kernelcore/spectre", branch = "main" }

Connecting to NATS and publishing/subscribing to events:

use spectre_events::EventBus;

let bus = EventBus::connect("nats://localhost:4222").await?;
bus.subscribe("llm.request.v1").await?;

See INTEGRATION.md for detailed integration guide (created below)

Publishing an Event

use spectre_events::{EventBus, Event, EventType};
use spectre_core::ServiceId;

#[tokio::main]
async fn main() -> spectre_core::Result<()> {
    // Connect to NATS
    let bus = EventBus::connect("nats://localhost:4222").await?;

    // Create event
    let event = Event::new(
        EventType::SystemMetrics,
        ServiceId::new("agent-os"),
        serde_json::json!({
            "cpu_percent": 45.2,
            "memory_mb": 2048,
            "disk_gb": 128
        }),
    );

    // Publish
    bus.publish(&event).await?;

    println!("Event published: {}", event.event_id);
    Ok(())
}

Subscribing to Events

use spectre_events::{EventBus, EventHandler, Subscriber, Event};

struct MyHandler;

#[async_trait::async_trait]
impl EventHandler for MyHandler {
    async fn handle(&self, event: Event) -> spectre_core::Result<()> {
        println!("Received event: {:?}", event);
        Ok(())
    }
}

#[tokio::main]
async fn main() -> spectre_core::Result<()> {
    let bus = EventBus::connect("nats://localhost:4222").await?;
    let nats_sub = bus.subscribe("system.metrics.v1").await?;

    let mut subscriber = Subscriber::new(nats_sub, "system.metrics.v1");

    // This blocks and listens for events
    subscriber.listen(MyHandler).await?;

    Ok(())
}
