+## Overview
+
+This document describes how to build the SONA Node.js native module from the Rust crate using NAPI-RS.
+
+## Prerequisites
+
+- Rust toolchain (1.70+)
+- Node.js (16+)
+- npm or yarn
+- @napi-rs/cli
+

+```
+
+## Build Steps
+
+### 1. Build the Rust crate with NAPI feature
+
+```bash
+cd /workspaces/ruvector/crates/sona
+cargo build --release --features napi
+```
+
+### 2. Build the Node.js module
+
+```bash
+cd /workspaces/ruvector/npm/packages/sona
+npm install
+npm run build
+```
+
+This will:
+- Install dependencies including `@napi-rs/cli`
+- Build the native module for your platform
+- Generate platform-specific `.node` files
+
+### 3. Run tests
+
+```bash
+npm test
+```
+
+### 4. Run examples
+
+```bash
+node examples/basic-usage.js
+node examples/custom-config.js
+node examples/llm-integration.js
+```
+
+## NAPI-RS Configuration
+
+The build is configured via `package.json`:
+
+```json
+{
+  "napi": {
+    "name": "sona",
+    "triples": {
+      "defaults": true,
+      "additional": [
+        "x86_64-unknown-linux-musl",
+        "aarch64-unknown-linux-gnu",
+        "armv7-unknown-linux-gnueabihf",
+        "aarch64-apple-darwin",
+        "x86_64-pc-windows-msvc",
+        "aarch64-pc-windows-msvc"
+      ]
+    }
+  }
+}
+```
+
+## Cross-Compilation
+
+To build for multiple platforms:
+
+```bash
+npm run build -- --target x86_64-unknown-linux-musl
+npm run build -- --target aarch64-apple-darwin
+npm run build -- --target x86_64-pc-windows-msvc
+```
+
+## Publishing
+
+### Prepare for publishing
+
+```bash
+napi prepublish -t npm
+```
+
+### Create universal binary (macOS)
+
+```bash
+napi universal
+```
+
+### Publish to npm
+
+```bash
+npm publish
+```
+
+## API Differences from Rust
+
+The NAPI bindings use a simplified API compared to the Rust API:
+
+### Rust API (via `begin_trajectory`)
+```rust
+let builder = engine.begin_trajectory(embedding);
+builder.add_step(activations, attention, reward);
+engine.end_trajectory(builder, quality);
+```
+
+### Node.js API (via trajectory ID)
+```javascript
+const trajId = engine.beginTrajectory(embedding);
+engine.addTrajectoryStep(trajId, activations, attention, reward);
+engine.setTrajectoryRoute(trajId, "route");
+engine.endTrajectory(trajId, quality);
+```
+
+This design avoids exposing the `TrajectoryBuilder` struct to JavaScript, which simplifies NAPI bindings.
+
+## Troubleshooting
+
+### Build fails with "could not find \`napi\`"
+
+Ensure you're building with the `napi` feature:
+```bash
+cargo build --features napi
+```
+
+### Module not found at runtime
+
+The native module must be built before running Node.js code:
+```bash
+npm run build
+```
+
+### Platform-specific issues
+
+Check that your Rust toolchain supports the target platform:
+```bash
+rustup target list
+rustup target add <target-triple>
+```
+
+## Performance Notes
+
+- The native module uses zero-copy for Float64Arrays where possible
+- Global trajectory storage uses `OnceLock` for thread-safe initialization
+- Mutex-protected HashMap for trajectory builders (minimal contention)
+
+## Memory Management
+
+- Trajectory builders are stored globally until `endTrajectory` is called
+- Finished trajectories are automatically cleaned up
+- No manual memory management required in JavaScript
+
+## Feature Flags
+
+The NAPI bindings respect these Cargo features:
+
+- `napi` - Enable NAPI bindings (required)
+- `serde-support` - Required by napi feature
+- `simd` - Enable SIMD optimizations (optional, recommended)
+
+Build with all features:
+```bash
+cargo build --release --features napi,simd
+```

+
+```javascript
+// Constructor
+new SonaEngine(hiddenDim: number)
+
+// Factory method with config
+SonaEngine.withConfig(config: SonaConfig): SonaEngine
+
+// Trajectory management (simplified API)
+beginTrajectory(queryEmbedding: Float64Array | number[]): number

+                   attentionWeights: Float64Array | number[], reward: number): void
+setTrajectoryRoute(trajectoryId: number, route: string): void
+addTrajectoryContext(trajectoryId: number, contextId: string): void
+endTrajectory(trajectoryId: number, quality: number): void
+
+// LoRA application
+applyMicroLora(input: Float64Array | number[]): Float64Array

+
+// Learning cycles
+tick(): string | null

+// Pattern search
+findPatterns(queryEmbedding: Float64Array | number[], k: number): LearnedPattern[]
+
+// Engine control
+getStats(): string
+setEnabled(enabled: boolean): void
+isEnabled(): boolean
+```
+
+## 🏗️ Architecture
+
+### Simplified Trajectory API
+
+Instead of exposing the `TrajectoryBuilder` struct to JavaScript (which would require complex NAPI bindings), we use a simpler ID-based API:
+
+**Rust Side:**
+- TrajectoryBuilder instances stored in global `HashMap<u32, TrajectoryBuilder>`
+- Thread-safe access via `Mutex` and `OnceLock`
+- Auto-cleanup when trajectory is ended
+
+**JavaScript Side:**
+- Numeric trajectory ID returned from `beginTrajectory()`
+- Use ID to add steps, set route, add context
+- Call `endTrajectory(id, quality)` to submit for learning
+
+### Type Conversions
+
+| Rust | JavaScript/TypeScript |
+|------|---------------------|
+| `Vec<f32>` | `Float64Array \| number[]` |
+| `Vec<f64>` | `Float64Array \| number[]` |
+| `u32` | `number` |
+| `bool` | `boolean` |
+| `String` | `string` |
+| `Option<T>` | `T \| null \| undefined` |
+
+## 📦 Build Output
+
+When built, the package will contain:
+- `index.js` - Platform detection and module loading
+- `index.d.ts` - TypeScript type definitions
+- `sona.*.node` - Native binary for each platform
+- `README.md` - Documentation
+- `package.json` - NPM metadata
+
+## 🚀 Next Steps
+
+To complete the integration:
+
+1. **Test Build**:
+   ```bash
+   cd /workspaces/ruvector/npm/packages/sona
+   npm install
+   npm run build
+   ```

+
+## Advanced Usage
+
+### LLM Integration Example
+
+```typescript
+import { SonaEngine } from '@ruvector/sona';
+
+class AdaptiveLLM {
+  private sona: SonaEngine;
+
+  constructor() {
+    this.sona = SonaEngine.withConfig({
+      hiddenDim: 4096,
+      microLoraRank: 2,
+      baseLoraRank: 16,
+      microLoraLr: 0.002,
+      qualityThreshold: 0.7,
+      backgroundIntervalMs: 1800000, // 30 minutes
+    });
+  }
+
+  async generate(prompt: string): Promise<string> {
+    const embedding = await this.embed(prompt);
+    const builder = this.sona.beginTrajectory(embedding);
+
+    // Generate with SONA-enhanced layers
+    const output = await this.runInference(builder);
+
+    // Calculate quality score
+    const quality = this.assessQuality(output);
+
+    // Submit trajectory for learning
+    this.sona.endTrajectory(builder, quality);
+
+    // Periodic background learning
+    const status = this.sona.tick();
+    if (status) {
+      console.log('Background learning:', status);
+    }
+
+    return output;
+  }
+
+  private async runInference(builder: TrajectoryBuilder): Promise<string> {
+    let output = '';
+
+    for (const layer of this.layers) {
+      // Get layer activations
+      const activations = layer.forward(/* ... */);
+      const attention = layer.getAttention();
+
+      // Apply micro-LoRA enhancement
+      const enhanced = this.sona.applyMicroLora(activations);
+
+      // Record step
+      const reward = this.calculateReward(enhanced);
+      builder.addStep(activations, attention, reward);
+
+      // Continue generation with enhanced activations
+      output += this.decode(enhanced);
+    }
+
+    return output;
+  }
+}
+```
+
+### Pattern-Based Routing
+
+```typescript
+// Find similar patterns for routing decisions
+const patterns = engine.findPatterns(queryEmbedding, 3);
+
+if (patterns.length > 0) {
+  const topPattern = patterns[0];
+
+  if (topPattern.patternType === 'CodeGen' && topPattern.avgQuality > 0.8) {
+    // Route to specialized code generation model
+    await routeToCodeModel(query);
+  } else if (topPattern.patternType === 'Reasoning') {
+    // Use chain-of-thought prompting
+    await useCoTPrompting(query);
+  }
+}
+```
+
+### Performance Monitoring
+
+```typescript
+// Get statistics
+const stats = JSON.parse(engine.getStats());
+console.log(`
+  Trajectories buffered: ${stats.trajectories_buffered}
+  Patterns learned: ${stats.patterns_learned}
+  Micro-LoRA updates: ${stats.micro_updates}
+  Background cycles: ${stats.background_cycles}
+`);
+
+// Force learning when needed
+if (stats.trajectories_buffered > 100) {
+  const result = engine.forceLearn();
+  console.log('Forced learning:', result);
+}
+```
+
+## Performance Characteristics
+
+- **Micro-LoRA Application**: <1ms per forward pass
+- **Trajectory Recording**: ~10μs per step
+- **Background Learning**: Depends on buffer size (typically 100-500ms for 1000 trajectories)
+- **Pattern Search**: O(k * n) where k = number of results, n = total patterns
+- **Memory Usage**: ~50MB base + ~1KB per trajectory + ~10KB per pattern
+
+## Architecture
+
+SONA implements a dual-loop learning architecture:
+
+1. **Instant Loop** (<1ms):
+   - Accumulates micro-LoRA gradients during inference
+   - Updates on every trajectory
+   - Rank-1 or rank-2 LoRA for minimal overhead
+
+2. **Background Loop** (periodic):
+   - Extracts patterns via k-means clustering
+   - Updates base LoRA weights
+   - Applies EWC++ for stability
+   - Prunes low-quality patterns
+
+## Requirements
+
+- Node.js >= 16
+- Native bindings for your platform (automatically installed)
+
+## Supported Platforms
+
+- Linux (x64, ARM64, ARM)
+- macOS (x64, ARM64, Universal)
+- Windows (x64, ARM64)
+- FreeBSD (x64)
