+# 🚨 Troubleshooting Guide
+
+Common issues and solutions for Brainy.
+
+## 🤖 Model Loading Issues
+
+### "Failed to load embedding model"
+
+**Symptoms**: Error during `brain.init()` with model loading failure.
+
+**Causes & Solutions**:
+
+1. **No local models + remote downloads blocked**
+   ```bash
+   # Solution: Download models manually
+   npm run download-models
+   ```
+
+2. **Network connectivity issues**
+   ```bash
+   # Solution: Allow remote models
+   export BRAINY_ALLOW_REMOTE_MODELS=true
+   
+   # Or pre-download in connected environment
+   npm run download-models
+   ```
+
+3. **Incorrect model path**
+   ```bash
+   # Check if models exist
+   ls ./models/Xenova/all-MiniLM-L6-v2/onnx/model.onnx
+   
+   # Set correct path
+   export BRAINY_MODELS_PATH=/correct/path/to/models
+   ```
+
+### Models Download Very Slowly
+
+**Symptoms**: Long wait times during first initialization.
+
+**Solutions**:
+```bash
+# Pre-download during build/CI
+npm run download-models
+
+# For Docker - download during image build
+RUN npm run download-models
+```
+
+### Container Out of Memory During Model Load
+
+**Symptoms**: OOM errors in Docker/Kubernetes during initialization.
+
+**Solutions**:
+```dockerfile
+# Increase memory limit
+docker run -m 2g my-app
+
+# Pre-download models at build time (recommended)
+RUN npm run download-models
+
+# Use quantized models (default, but explicit)
+ENV BRAINY_MODEL_DTYPE=q8
+```
+
+## 💾 Storage Issues
+
+### Permission Denied Creating Storage Directory
+
+**Symptoms**: EACCES or permission errors when creating storage files.
+
+**Solutions**:
+```bash
+# Make directory writable
+chmod 755 ./brainy-data
+
+# Use custom writable path
+const brain = new BrainyData({
+  storage: {
+    adapter: 'filesystem',
+    path: '/tmp/brainy-data'
+  }
+})
+
+# Or use memory storage
+const brain = new BrainyData({
+  storage: { forceMemoryStorage: true }
+})
+```
+
+### "ENOENT: no such file or directory"
+
+**Symptoms**: File not found errors during storage operations.
+
+**Solutions**:
+```bash
+# Ensure parent directory exists
+mkdir -p ./brainy-data
+
+# Check storage configuration
+const brain = new BrainyData({
+  storage: {
+    adapter: 'filesystem',
+    path: '/full/path/to/storage' // Use absolute path
+  }
+})
+```
+
+## 🧠 Initialization Issues
+
+### Initialization Hangs or Times Out
+
+**Symptoms**: `brain.init()` never resolves.
+
+**Possible Causes & Solutions**:
+
+1. **Model download timeout**
+   ```bash
+   # Pre-download models
+   npm run download-models
+   
+   # Or force local-only
+   export BRAINY_ALLOW_REMOTE_MODELS=false
+   ```
+
+2. **Network issues**
+   ```typescript
+   // Set initialization timeout
+   const brain = new BrainyData()
+   
+   // Use Promise.race for timeout
+   const initPromise = Promise.race([
+     brain.init(),
+     new Promise((_, reject) => 
+       setTimeout(() => reject(new Error('Init timeout')), 30000)
+     )
+   ])
+   ```
+
+3. **Resource constraints**
+   ```bash
+   # Increase memory for Node.js
+   NODE_OPTIONS="--max-old-space-size=4096" npm start
+   ```
+
+## 🔍 Search Issues
+
+### No Search Results
+
+**Symptoms**: Empty results from valid queries.
+
+**Debugging Steps**:
+
+1. **Check if data exists**
+   ```typescript
+   const stats = await brain.getStatistics()
+   console.log(`Total items: ${stats.nounCount}`)
+   ```
+
+2. **Verify embedding generation**
+   ```typescript
+   const id = await brain.add("test content")
+   const item = await brain.get(id)
+   console.log('Item:', item) // Should have metadata and vector
+   ```
+
+3. **Test with exact match**
+   ```typescript
+   const results = await brain.search("test content") // Exact text
+   console.log('Exact match results:', results)
+   ```
+
+### Poor Search Quality
+
+**Symptoms**: Irrelevant results, low scores.
+
+**Improvements**:
+
+1. **Add more context to queries**
+   ```typescript
+   // Instead of: "cat"
+   const results = await brain.search("domestic cat animal pet")
+   ```
+
+2. **Use metadata filtering**
+   ```typescript
+   const results = await brain.search("animals", {
+     where: { category: "pets" },
+     limit: 10
+   })
+   ```
+
+3. **Check data quality**
+   ```typescript
+   // Ensure consistent, descriptive content
+   await brain.add("Domestic cat - small carnivorous mammal", {
+     category: "animals",
+     subcategory: "pets"
+   })
+   ```
+
+## ⚡ Performance Issues
+
+### Slow Search Performance
+
+**Symptoms**: High search latency.
+
+**Optimizations**:
+
+1. **Enable search cache**
+   ```typescript
+   const brain = new BrainyData({
+     cache: {
+       search: {
+         maxSize: 1000,
+         ttl: 300000 // 5 minutes
+       }
+     }
+   })
+   ```
+
+2. **Use appropriate limits**
+   ```typescript
+   // Don't fetch more than needed
+   const results = await brain.search("query", { limit: 10 })
+   ```
+
+3. **Consider metadata filtering first**
+   ```typescript
+   // Filter by metadata first, then semantic search
+   const results = await brain.search("query", {
+     where: { category: "specific" }, // Reduces search space
+     limit: 10
+   })
+   ```
+
+### High Memory Usage
+
+**Symptoms**: Increasing memory consumption over time.
+
+**Solutions**:
+
+1. **Cleanup when done**
+   ```typescript
+   await brain.cleanup() // Releases resources
+   ```
+
+2. **Use streaming for large datasets**
+   ```typescript
+   // Process in batches instead of loading all at once
+   for (let i = 0; i < data.length; i += 100) {
+     const batch = data.slice(i, i + 100)
+     await Promise.all(batch.map(item => brain.add(item)))
+   }
+   ```
+
+3. **Configure memory limits**
+   ```bash
+   NODE_OPTIONS="--max-old-space-size=2048" npm start
+   ```
+
+## 🧪 Testing Issues
+
+### Tests Fail in CI/CD
+
+**Symptoms**: Tests pass locally but fail in automated environments.
+
+**Solutions**:
+
+1. **Pre-download models in CI**
+   ```yaml
+   # .github/workflows/test.yml
+   - name: Download Models
+     run: npm run download-models
+   
+   - name: Test with Local Models
+     env:
+       BRAINY_ALLOW_REMOTE_MODELS: false
+     run: npm test
+   ```
+
+2. **Use memory storage in tests**
+   ```typescript
+   // In test setup
+   const brain = new BrainyData({
+     storage: { forceMemoryStorage: true }
+   })
+   ```
+
+3. **Increase timeout for CI**
+   ```typescript
+   // In test files
+   describe('Brainy tests', () => {
+     it('should work', async () => {
+       // Test code
+     }, { timeout: 30000 }) // 30 second timeout
+   })
+   ```
+
+## 📋 Environment-Specific Issues
+
+### Browser CORS Errors
+
+**Symptoms**: Model loading fails in browser due to CORS.
+
+**Solutions**:
+```javascript
+// Brainy handles CORS automatically via CDN
+// No action needed - models load from CORS-enabled mirrors
+
+// If using custom model URLs, ensure CORS headers:
+// Access-Control-Allow-Origin: *
+```
+
+### Serverless Cold Start Timeouts
+
+**Symptoms**: Lambda/Vercel functions timeout during initialization.
+
+**Solutions**:
+```dockerfile
+# Pre-bundle models in deployment
+RUN npm run download-models
+
+# Set environment variables
+ENV BRAINY_ALLOW_REMOTE_MODELS=false
+ENV BRAINY_MODELS_PATH=./models
+```
+
+### Node.js Module Resolution Issues
+
+**Symptoms**: "Cannot find module" errors.
+
+**Solutions**:
+```json
+// package.json
+{
+  "type": "module",
+  "exports": {
+    ".": {
+      "import": "./dist/index.js",
+      "require": "./dist/index.js"
+    }
+  }
+}
+```
+
+## 🆘 Getting Help
+
+### Debug Logging
+
+Enable verbose logging to see what's happening:
+
+```typescript
+const brain = new BrainyData({
+  logging: { verbose: true }
+})
+```
+
+### Health Check
+
+Verify your Brainy setup:
+
+```typescript
+// Basic health check
+try {
+  const brain = new BrainyData()
+  await brain.init()
+  
+  const id = await brain.add("health check")
+  const results = await brain.search("health")
+  
+  console.log('✅ Brainy is working correctly')
+  console.log(`Added item: ${id}`)
+  console.log(`Search results: ${results.length}`)
+  
+} catch (error) {
+  console.error('❌ Brainy health check failed:', error)
+}
+```
+
+### Environment Info
+
+Collect environment information:
+
+```bash
+# Node.js version
+node --version
+
+# Memory limits
+node -e "console.log(process.memoryUsage())"
+
+# Platform info
+node -e "console.log(process.platform, process.arch)"
+
+# Brainy models
+ls -la ./models/Xenova/all-MiniLM-L6-v2/
+```
