phantom_os 0.1.0

An asynchronous, distributed operating system framework with IIT-based ECS architecture
# PhantomOS

An asynchronous, distributed operating system framework with integrated information theory (IIT) based entity component system (ECS) architecture.

## Overview

PhantomOS is an experimental operating system built in Rust, designed around principles of emergence, resonance, and integrated information. It combines:

- **Distributed Event Bus** - Async message passing between system components
- **ECS Graph Architecture** - Entity-component system with graph-based topology
- **Field-Based Computing** - Resonant field synthesis for state management
- **Adaptive Control** - Self-tuning controllers based on feedback signals
- **Safety Kernel** - Runtime validation and safety enforcement

## Components

### Core Modules

| Module | Description |
|--------|-------------|
| `bus` | Event bus for local message passing |
| `dist_bus` | Distributed event bus for cluster communication |
| `kernel` | Main system bootstrap and lifecycle |
| `sensors` | Hardware abstraction for sensor input |
| `signal_engine` | Signal processing and system state synthesis |
| `control_engine` | PID-like control with actuator commands |
| `safety` | Runtime safety validation and alerting |

### ECS Modules

| Module | Description |
|--------|-------------|
| `ecs/graph` | Graph structure for entity relationships |
| `ecs/node` | Distributed ECS node implementation |
| `ecs_solver` | IIT-based Phi maximization approximation |

### Field & Adaptive Modules

| Module | Description |
|--------|-------------|
| `field/state` | Field state and system state structs |
| `field/engine` | Field synthesis from system state |
| `adaptive/controller` | Self-tuning adaptive controller |

### Scheduler Modules

| Module | Description |

| `scheduler/spectral` | Graph Laplacian computation |

## Quick Start

### Prerequisites

- Rust 1.70+ with Cargo
- Tokio runtime (included via dependencies)

### Build

```bash
cargo build --release
```

### Run

```bash
cargo run
```

### Check

```bash
cargo check
```

## Configuration

Key parameters in `src/main.rs`:

```rust
let bus = DistributedBus::new(2048);        // Event buffer size
let graph = ECSGraph::new(10_000);           // Graph node capacity
let aggregator = Aggregator::new(bus.clone(), 10_000);  // Mask size
```

## System State

The system maintains a `SystemState` with three core metrics:

- **Entropy** - Measure of disorder (0.0 - ∞)
- **Coherence** - Phase alignment (0.0 - 1.0)
- **Resonance** - Oscillatory coupling (0.0 - ∞)

## Events

### Local Events (`bus::Event`)
- `SensorFrame` - Raw sensor data
- `SystemState` - Processed state
- `ControlCommand` - Actuator outputs
- `SafetyAlert` - Safety violations

### Distributed Events (`dist_bus::DistributedEvent`)
- `SystemState` - Shared state across nodes
- `FieldState` - Synthesized field representation
- `Feedback` - Control feedback signals
- `EntityMigration` - Topology rebalancing
- `SafetyAlert` - Distributed safety alerts

## Safety Limits

Configurable in `src/safety/kernel.rs`:

```rust
const MAX_ENERGY: f64 = 10.0;      // Per-command limit
const MAX_AMPLITUDE: f64 = 1000.0;  // Field amplitude limit
```

## Architecture Decisions

1. **Async/Await** - All I/O and event handling is non-blocking
2. **Broadcast Channels** - Tokio broadcast for pub/sub event distribution
3. **Arc + Mutex** - Shared state management across tasks
4. **Graph Topology** - Entity relationships modeled as weighted graphs
5. **Spectral Methods** - Laplacian-based topology analysis
