+# 🧠 Brainy 2.0 Final API Reference
+
+> **The definitive API - Clean, Correct, Complete**
+
+## ✅ KEY CORRECTIONS FROM REVIEW:
+1. **Brainy Operators (NOT MongoDB)** - `greaterThan` not `$gt`
+2. **Neural API is complete** - All methods available via `brain.neural`
+3. **Code is correct** - Implementation uses right operators, just docs were wrong
+4. **Nothing lost** - All features still present, just reorganized
+

+
+## 📚 CORE DATA OPERATIONS
+
+### Nouns
+```typescript
+// Single
+addNoun(textOrVector, metadata?)           // Auto-embeds text!
+getNoun(id)
+updateNoun(id, textOrVector?, metadata?)
+deleteNoun(id)
+hasNoun(id)
+
+// Metadata
+getNounMetadata(id)
+updateNounMetadata(id, metadata)
+getNounWithVerbs(id)
+
+// Batch
+addNouns(items[])
+getNouns(idsOrOptions)                    // Unified: IDs, filter, or pagination
+deleteNouns(ids[])
+```
+
+### Verbs
+```typescript
+addVerb(source, target, type, metadata?)
+getVerb(id)
+deleteVerb(id)
+getVerbsBySource(sourceId)
+getVerbsByTarget(targetId)
+getVerbsByType(type)
+```
+
+## 🔍 SEARCH
+
+Just TWO methods - simple and powerful:
+
+```typescript
+search(query, k?)         // Convenience: same as find({like: query, limit: k})
+find(query)              // TRIPLE INTELLIGENCE: Vector + Graph + Field
+```
+
+### Find Query (with CORRECT Brainy Operators):
+```typescript
+find({
+  // Vector
+  like: 'text' | vector | {id: 'noun-id'},
+  
+  // Fields (BRAINY operators, NOT MongoDB!)
+  where: {
+    field: value,                    // Direct equality
+    field: {
+      equals: value,
+      greaterThan: value,           // NOT $gt
+      lessThan: value,              // NOT $lt
+      greaterEqual: value,
+      lessEqual: value,
+      oneOf: [values],              // NOT $in
+      notOneOf: [values],           // NOT $nin
+      contains: value,
+      startsWith: value,
+      endsWith: value,
+      matches: pattern,             // NOT $regex
+      between: [min, max]
+    }
+  },
+  
+  // Graph
+  connected: {
+    to: 'id',
+    from: 'id',
+    via: 'type',
+    depth: 2
+  },
+  
+  // Control
+  limit: 10,
+  offset: 0,
+  explain: true
+})
+```
+
+## 🧠 NEURAL API
+
+Complete and available via `brain.neural`:
+
+```typescript
+brain.neural.similar(a, b)              // Similarity 0-1
+brain.neural.clusters()                 // Auto-clustering
+brain.neural.hierarchy(id)              // Semantic tree
+brain.neural.neighbors(id, k?)          // K-nearest
+brain.neural.outliers(threshold?)       // Outlier detection
+brain.neural.semanticPath(from, to)     // Path finding
+brain.neural.visualize(options?)        // For D3/Cytoscape/GraphML
+
+// Performance
+brain.neural.clusterFast()              // O(n) HNSW
+brain.neural.clusterLarge()             // Million+ items
+brain.neural.clusterStream()            // Progressive
+```
+
+### Visualization Format:
+```typescript
+brain.neural.visualize({
+  maxNodes: 100,
+  dimensions: 2,
+  algorithm: 'force',
+  includeEdges: true
+})
+// Returns: {
+//   format: 'd3' | 'cytoscape' | 'graphml',
+//   nodes: [...], edges: [...], layout: {...}
+// }
+```
+
+## 📥 IMPORT
+
+Simple, AI-powered:
+
+```typescript
+brain.neuralImport(data, options?)      // Auto-detects format!
+// Options: {
+//   confidenceThreshold: 0.7,
+//   autoApply: false,
+//   skipDuplicates: true
+// }
+```
+
+## 🎯 INTELLIGENCE
+
+```typescript
+// Verb Scoring
+provideFeedbackForVerbScoring(feedback)
+getVerbScoringStats()
+exportVerbScoringLearningData()
+importVerbScoringLearningData(data)
+
+// Embeddings
+embed(text)                             // Generate vector
+calculateSimilarity(a, b, metric?)      // Compare
+```
+
+## 🔄 SYNC
+
+```typescript
+// Remote
+connectToRemoteServer(url)
+disconnectFromRemoteServer()
+isConnectedToRemoteServer()
+
+// Real-time
+enableRealtimeUpdates(config)
+disableRealtimeUpdates()
+checkForUpdatesNow()
+
+// Search modes
+searchLocal(query, k?)
+searchRemote(query, k?)
+searchCombined(query, k?)
+```
+
+## 📊 MONITORING
+
+```typescript
+size()                                  // Total nouns
+getStatistics()                         // Full stats
+getHealthStatus()                       // Health
+getCacheStats()                         // Cache
+clearCache()                            // Clear
+```
+
+## ⚙️ CONFIGURATION
+
+```typescript
+// Modes
+setReadOnly(bool)
+setWriteOnly(bool)
+setFrozen(bool)
+
+// Augmentations
+augmentations.register(aug)
+augmentations.list()
+augmentations.get(name)
+```
+
+## 💾 DATA MANAGEMENT
+
+```typescript
+clear(options?)                         // Clear all
+clearNouns()                           // Nouns only
+clearVerbs()                           // Verbs only
+backup()                               // Create backup
+restore(backup)                        // Restore
+rebuildMetadataIndex()                 // Rebuild index
+```
+
+## 🚀 LIFECYCLE
+
+```typescript
+const brain = new BrainyData({
+  storage: 'auto',                     // auto | memory | filesystem | s3
+  dimensions: 384,
+  cache: true,
+  index: true
+})
+
+await brain.init()                     // REQUIRED!
+await brain.shutdown()                 // Cleanup
+
+// Static
+BrainyData.preloadModel()              // Preload
+BrainyData.warmup()                    // Warmup
+```
