# SONA Integration Guide

Integration of `@ruvector/sona` package (v0.1.5) into the V3 Neural Module.

## Overview

The SONA (Self-Optimizing Neural Architecture) integration provides runtime-adaptive learning capabilities with sub-millisecond performance:

- **Learning Performance**: <0.05ms per trajectory (target)
- **Adaptation Performance**: <0.1ms per context
- **Memory Efficient**: LoRA-based (1-16 rank)
- **Platform Support**: WASM + Node.js (NAPI bindings)

## Installation

The package is already installed as a dependency:

```bash
npm install @ruvector/sona@0.1.5
```

## Quick Start

```typescript
import {
  createSONALearningEngine,
  type Trajectory,
  type Context,
} from '@claude-flow/neural';
import { getModeConfig } from '@claude-flow/neural';

// Create SONA engine with balanced mode
const modeConfig = getModeConfig('balanced');
const sona = createSONALearningEngine('balanced', modeConfig);

// Learn from a trajectory
const trajectory: Trajectory = {
  trajectoryId: 'traj-001',
  context: 'Implement authentication',
  domain: 'code',
  steps: [
    {
      stepId: 'step-1',
      timestamp: Date.now(),
      action: 'analyze requirements',
      stateBefore: new Float32Array(768).fill(0.1),
      stateAfter: new Float32Array(768).fill(0.2),
      reward: 0.8,
    },
    // ... more steps
  ],
  qualityScore: 0.88,
  isComplete: true,
  startTime: Date.now(),
};

await sona.learn(trajectory);
console.log(`Learning time: ${sona.getLearningTime()}ms`);

// Adapt to new context
const context: Context = {
  domain: 'code',
  queryEmbedding: new Float32Array(768).fill(0.15),
};

const adapted = await sona.adapt(context);
console.log(`Confidence: ${adapted.confidence}`);
console.log(`Suggested route: ${adapted.suggestedRoute}`);
```

## API Reference

### `SONALearningEngine`

## Examples

See `/examples/sona-usage.ts` for comprehensive examples:

1. **Basic Learning**: Learn from trajectories
2. **Context Adaptation**: Adapt behavior to new contexts
3. **Pattern Discovery**: Discover and cluster patterns
4. **Performance Monitoring**: Benchmark learning performance

Run examples:

```bash
cd v3/@claude-flow/neural
npx tsx examples/sona-usage.ts
```

## Integration with V3 Neural Module

The SONA integration works seamlessly with other V3 neural components:

```typescript
import { createNeuralLearningSystem } from '@claude-flow/neural';

const system = createNeuralLearningSystem('balanced');
await system.initialize();

// SONA is used internally by the neural system
const taskId = system.beginTask('Implement feature X', 'code');

// Record steps...
system.recordStep(
  taskId,
  'analyze requirements',
  0.8,
  queryEmbedding
);

// Complete and trigger SONA learning
await system.completeTask(taskId, 0.9);
```

## Platform Support

SONA uses native bindings for optimal performance:

- **Linux**: x64, ARM64 (GNU, MUSL)
- **macOS**: x64, ARM64 (Universal binary)
- **Windows**: x64, ARM64 (MSVC)

Runtime selection is automatic based on platform.

## Advanced Usage

### Custom Configuration

```typescript
import { SonaEngine, type JsSonaConfig } from '@ruvector/sona';

const customConfig: JsSonaConfig = {
  hiddenDim: 512,
  embeddingDim: 512,
  microLoraRank: 2,
  baseLoraRank: 8,
  microLoraLr: 0.002,
  baseLoraLr: 0.0002,
  ewcLambda: 1000.0,
  patternClusters: 100,
  trajectoryCapacity: 20000,
  backgroundIntervalMs: 1800000,
  qualityThreshold: 0.6,
  enableSimd: true,
};

const engine = SonaEngine.withConfig(customConfig);
```

### Background Learning

SONA automatically runs background learning cycles:

```typescript
// Tick periodically (e.g., every second)
setInterval(() => {
  const status = sona.tick();
  if (status) {
    console.log('Background learning:', status);
  }
}, 1000);
```

Or force immediate learning:

```typescript
const status = sona.forceLearning();
console.log(status);
```

## Troubleshooting

### Learning is too slow

- Use `'real-time'` or `'edge'` mode
- Reduce `baseLoraRank` in config
- Enable SIMD optimizations (`enableSimd: true`)

### Memory usage too high

- Use `'edge'` mode
- Reduce `trajectoryCapacity`
- Reduce `patternClusters`
- Lower `hiddenDim` and `embeddingDim`

### Patterns not forming

- Increase `trajectoryCapacity`
- Lower `qualityThreshold`
- Increase `backgroundIntervalMs`
- Call `forceLearning()` manually
