feat: enforce data/metadata separation, numeric range queries, improved docs

Browse source 
- Store data opaquely in add() and update() instead of spreading object
  properties into top-level metadata. data is for semantic search (HNSW),
  metadata is for structured where-filter queries (MetadataIndex).
- Fix numeric range queries in MetadataIndex — use numeric-aware comparison
  instead of lexicographic string comparison for normalized values.
- Add data field to RelateParams and Relation types for relationship content.
- Add where.type → where.noun alias in metadata-only find() path.
- Rewrite README: focused ~350 lines from 791, quick start first, feature
  showcase with mini-snippets, organized doc links, no version callouts.
- Add DATA_MODEL.md and QUERY_OPERATORS.md reference docs.
- Remove 10 outdated/redundant doc files consolidated into API reference.
- Improve JSDoc on Entity, Relation, AddParams, FindParams, and core methods.
- Fix tests asserting data properties appear in metadata (data model violation).
- Deprecate verb.source/target in favor of from/to (public) and sourceId/targetId (storage).

## The Knowledge Operating System **Three database paradigms. One API. Zero configuration.**
**Every piece of knowledge in your application — living, connected, and intelligent.** Built because we were tired of stitching together Pinecone + Neo4j + MongoDB and spending weeks on configuration before writing a single line of business logic. Brainy unifies vector search, graph traversal, and metadata filtering so you don't have to choose.
Stop fighting with vector databases, graph databases, and document stores. Stop stitching together Pinecone + Neo4j + MongoDB. **Brainy does all three, in one elegant API, from prototype to planet-scale.**
```javascript
const brain = new Brainy()
await brain.init()
// That's it. You now have semantic search, graph relationships,
// and document filtering. Zero configuration. Just works.
```
**Built by developers who were tired of:**
- Spending weeks configuring embeddings, indexes, and schemas
- Choosing between vector similarity OR graph relationships OR metadata filtering
- Rewriting everything when you need to scale from 1,000 to 1,000,000,000 entities
**Brainy makes the impossible simple: All three paradigms. One API. Any scale.**

## Entity Extraction (NEW in v5.7.6) ## Three Indexes, One Query
**Extract entities from text with AI-powered classification:** Every piece of knowledge lives in three indexes simultaneously:
- **`data`** → **Vector index** — Content for semantic search. Strings auto-embed into 384-dim vectors. Queried with `find({ query: '...' })`.
- **`metadata`** → **Metadata index** — Structured fields for filtering. O(1) lookups. Queried with `find({ where: { ... } })`.
- **`relate()`** → **Graph index** — Typed, directed relationships between entities. Traversed with `find({ connected: { ... } })`.
```javascript ```javascript
import { Brainy, NounType } from '@soulcraft/brainy' // Data → vector index (semantic search)
const articleId = await brain.add({
const brain = new Brainy() data: 'A deep dive into transformer architectures',
await brain.init() type: NounType.Document,
metadata: { author: 'Dr. Chen', year: 2024, tags: ['AI'] } // → metadata index
// Extract all entities
const entities = await brain.extractEntities('John Smith founded Acme Corp in New York')
// Returns:
// [
// { text: 'John Smith', type: NounType.Person, confidence: 0.95 },
// { text: 'Acme Corp', type: NounType.Organization, confidence: 0.92 },
// { text: 'New York', type: NounType.Location, confidence: 0.88 }
// ]
// Extract with filters
const people = await brain.extractEntities(resume, {
types: [NounType.Person],
confidence: 0.8
}) })
// Advanced: Direct access to extractors // Relationships → graph index
import { SmartExtractor } from '@soulcraft/brainy' await brain.relate({ from: authorId, to: articleId, type: VerbType.Authored })
const extractor = new SmartExtractor(brain, { minConfidence: 0.7 }) // Query all three at once
const result = await extractor.extract('CEO', { brain.find({
formatContext: { format: 'excel', columnHeader: 'Title' } query: 'attention mechanisms', // Vector similarity
where: { year: { greaterThan: 2023 } }, // Metadata filter
connected: { from: authorId, depth: 1 } // Graph traversal
}) })
``` ```

## From Prototype to Planet Scale ## Features
**The same API. Zero rewrites. Any scale.** ### Triple Intelligence
Vector search + graph traversal + metadata filtering in every query. No stitching services together — one `find()` call combines all three.
### 👤 Individual Developer → Weekend Prototype
```javascript ```javascript
const brain = new Brainy() // Zero config, starts in memory const results = await brain.find({
await brain.init() query: 'machine learning',
``` where: { department: 'engineering', level: 'senior' },
**Perfect for:** Hackathons, side projects, prototyping, learning connected: { from: teamLeadId, via: VerbType.WorksWith, depth: 2 }
### 👥 Small Team → Production MVP
```javascript
const brain = new Brainy({
storage: { type: 'filesystem', path: './data', compression: true }
}) })
``` ```
**Scale:** Thousands to hundreds of thousands • **Performance:** <5ms queries
**→ [Production Service Architecture](docs/PRODUCTION_SERVICE_ARCHITECTURE.md)** — Singleton patterns, caching, and scaling for Bun/Node.js services
### 🏢 Growing Company → Multi-Million Scale ### Hybrid Search
Automatically combines keyword (text) and semantic (vector) search. No configuration needed.
```javascript ```javascript
const brain = new Brainy({ await brain.find({ query: 'David Smith' }) // Auto: text + semantic
storage: { type: 's3', s3Storage: { bucketName: 'my-kb', region: 'us-east-1' } }, await brain.find({ query: 'AI concepts', searchMode: 'semantic' }) // Semantic only
hnsw: { typeAware: true } await brain.find({ query: 'exact id', searchMode: 'text' }) // Text only
```
### Query Operators
Filter metadata with equality, comparison, array, existence, pattern, and logical operators:
```javascript
await brain.find({
where: {
status: 'active', // Exact match
score: { greaterThan: 90 }, // Comparison
tags: { contains: 'ai' }, // Array
anyOf: [{ role: 'admin' }, { role: 'owner' }] // Logical OR
}
}) })
``` ```
**Scale:** Millions of entities • **Performance:** <10ms queries (measured at 1M scale)
### 🌍 Enterprise → Billion+ Scale **[Query Operators Reference](docs/QUERY_OPERATORS.md)** — all operators with indexed/in-memory matrix
### Graph Relationships
Typed, directed edges between entities. Traverse connections at any depth.
```javascript ```javascript
const brain = new Brainy({ await brain.relate({ from: personId, to: projectId, type: VerbType.WorksOn })
storage: { type: 'gcs', gcsStorage: { bucketName: 'global-kb' } },
hnsw: { typeAware: true, M: 32, efConstruction: 400 } const results = await brain.find({
connected: { from: personId, via: VerbType.WorksOn, depth: 3 }
}) })
``` ```
**Scale:** PROJECTED billion+ (extrapolated from 10M tests, not tested at 1B)
**Cost:** $138k/year → $6k/year with intelligent tiering (96% savings)
**→ [Capacity Planning Guide](docs/operations/capacity-planning.md)** | **[Cost Optimization](docs/operations/)** ### Git-Style Branching
### 🎯 The Point Fork your entire database in <100ms. Snowflake-style copy-on-write.
**Start simple. Scale infinitely. Never rewrite.**
Most systems make you choose: Simple (SQLite) OR Scalable (Kubernetes + 7 databases).
**Brainy gives you both.** Starts simple as SQLite. Scales like Google.

## Why Brainy Is Revolutionary
### 🧠 **Triple Intelligence™** — The Impossible Made Possible
**The world's first to unify three database paradigms in ONE API:**
| What You Get | Like Having | But Unified |
|-------------|-------------|-------------|
| 🔍 **Vector Search** | Pinecone, Weaviate | Find by meaning |
| 🕸️ **Graph Relationships** | Neo4j, ArangoDB | Navigate connections |
| 📊 **Document Filtering** | MongoDB, Elasticsearch | Query metadata |
**Every other system makes you choose.** Brainy does all three together.
**Why this matters:** Your data isn't just vectors or just documents or just graphs. It's all three at once. A research paper is semantically similar to other papers (vector), written by an author (graph), and published in 2023 (document). **Brainy is the only system that understands this.**
### 🎯 **42 Noun Types × 127 Verb Types = Universal Protocol**
Model **any domain** with mathematical completeness:
```
42 Nouns × 127 Verbs × ∞ Metadata = 5,334+ base combinations
Stage 3 CANONICAL: 96-97% coverage of all human knowledge
```
**Real-world expressiveness:**
- Healthcare: `Patient → diagnoses → Condition`
- Finance: `Account → transfers → Transaction`
- Manufacturing: `Product → assembles → Component`
- Education: `Student → completes → Course`
- **YOUR domain** → Your types + relationships = Your knowledge graph
[→ See the Mathematical Proof](docs/architecture/noun-verb-taxonomy.md)
### ⚡ **Zero Configuration Philosophy**
**We hate configuration files. So we eliminated them.**
```javascript ```javascript
const brain = new Brainy() // Auto-detects everything
await brain.init() // Optimizes for your environment
```
Brainy automatically:
- Detects optimal storage (memory/filesystem/cloud)
- Configures memory based on available RAM
- Optimizes for containers (Docker/K8s)
- Tunes indexes for your data patterns
- Manages embedding models and caching
**You write business logic. Brainy handles infrastructure.**
### 🚀 **Git-Style Version Control** — Database & Entity Level (v5.0.0+)
**Clone your entire database in <100ms. Track every entity change. Full Git-style workflow.**
```javascript
// Fork instantly - Snowflake-style copy-on-write
const experiment = await brain.fork('test-migration') const experiment = await brain.fork('test-migration')
await experiment.add({ data: 'test data', type: NounType.Concept })
// Make changes safely in isolation await experiment.commit({ message: 'Add test data', author: 'dev@co.com' })
await experiment.add({ type: 'user', data: { name: 'Test User' } })
await experiment.updateAll({ /* migration logic */ })
// Commit your work
await experiment.commit({ message: 'Add test user', author: 'dev@example.com' })
// Switch to experimental branch to make it active
await brain.checkout('test-migration') await brain.checkout('test-migration')
// Time-travel: Query database at any past commit (read-only) // Time-travel: query at any past commit
const commits = await brain.getHistory({ limit: 10 }) const snapshot = await brain.asOf(commitId)
const snapshot = await brain.asOf(commits[5].id)
const pastResults = await snapshot.find({ query: 'historical data' }) const pastResults = await snapshot.find({ query: 'historical data' })
await snapshot.close() await snapshot.close()
// Entity versioning: Track changes to individual entities (v5.3.0+)
const userId = await brain.add({ type: 'user', data: { name: 'Alice' } })
await brain.versions.save(userId, { tag: 'v1.0', description: 'Initial profile' })
await brain.update(userId, { data: { name: 'Alice Smith', role: 'admin' } })
await brain.versions.save(userId, { tag: 'v2.0', description: 'Added role' })
// Compare versions or restore previous state
const diff = await brain.versions.compare(userId, 1, 2) // See what changed
await brain.versions.restore(userId, 1) // Restore v1.0
``` ```
**Database-level version control (v5.0.0):** **[Branching Documentation](docs/features/instant-fork.md)**
- ✅ `fork()` - Instant clone in <100ms
- ✅ `merge()` - Merge with conflict resolution
- ✅ `commit()` - Snapshot state
- ✅ `asOf()` - Time-travel queries (query at any commit)
- ✅ `getHistory()` - View commit history
- ✅ `checkout()`, `listBranches()` - Full branch management
- ✅ CLI support for all features
**Entity-level version control (v5.3.0):** ### Entity Versioning
- ✅ `versions.save()` - Save entity snapshots with tags
- ✅ `versions.restore()` - Restore previous versions
- ✅ `versions.compare()` - Diff between versions
- ✅ `versions.list()` - View version history
- ✅ Automatic deduplication (content-addressable storage)
**How it works:** Snowflake-style COW shares HNSW index structures, copying only modified nodes (10-20% memory overhead). Save, restore, and compare entity snapshots.
**Perfect for:** Safe migrations, A/B testing, feature branches, distributed development, time-travel debugging, audit trails, document versioning, compliance tracking

**Examples:** Code search, research platforms, content discovery, recommendation engines
### 🏢 **Enterprise Knowledge Management**
Corporate memory that never forgets. Track every customer interaction, product evolution, and business relationship.
**Examples:** CRM systems, product catalogs, customer intelligence, institutional knowledge
### 🎮 **Rich Interactive Experiences**
NPCs that remember. Characters that persist across stories. Worlds that evolve based on real relationships.
**Examples:** Game worlds, interactive fiction, educational platforms, creative tools
### 🎨 **Content & Media Platforms**
Every asset knows its relationships. Intelligent tagging, similarity-based discovery, and relationship-aware management.
**Examples:** DAM systems, media libraries, writing assistants, content management
**The pattern:** Knowledge that needs to live, connect, and evolve. That's what Brainy was built for.

// Just works - no configuration needed const vfs = brain.vfs
const results = await brain.find({ query: 'David Smith' })
// Finds exact text matches AND semantically similar content
// Override when needed await vfs.writeFile('/docs/readme.md', 'Project documentation')
await brain.find({ query: 'exact match', searchMode: 'text' }) // Text only const content = await vfs.readFile('/docs/readme.md')
await brain.find({ query: 'AI concepts', searchMode: 'semantic' }) // Semantic only const tree = await vfs.getTreeStructure('/docs', { maxDepth: 3 })
await brain.find({ query: 'hybrid', hybridAlpha: 0.3 }) // Custom weighting
// Highlight structured content (v7.8.0) — plain text, JSON, HTML, Markdown
const highlights = await brain.highlight({
query: 'warrior',
text: entity.data // Auto-detects TipTap, Slate, Lexical, HTML, Markdown
})
// Each highlight has: text, score, position, matchType, contentCategory
```

const status = await brain.storage.getStorageStatus()
```
### 📊 Adaptive Memory Management
Auto-scales 2GB → 128GB+ based on environment:
- Container-aware (Docker/K8s cgroups)
- Environment-optimized (dev/staging/production)
- Built-in cache monitoring with tuning recommendations
```javascript
const stats = brain.getCacheStats() // Performance insights
```
**[📖 Capacity Planning Guide →](docs/operations/capacity-planning.md)**
### Native Acceleration (Optional)
Install `@soulcraft/cortex` for Rust-powered native acceleration: SIMD distance calculations, native metadata/graph indexes, CRoaring bitmaps, and Candle ML embeddings.
```bash
npm install @soulcraft/cortex
```
```typescript
const brain = new Brainy({
plugins: ['@soulcraft/cortex']
})
await brain.init()
// [brainy] Plugin activated: @soulcraft/cortex
```
Plugins are opt-in — brainy never auto-imports packages unless you list them in `plugins`.

## Why Brainy Exists
**The Vision:** Traditional systems force you to choose between vector databases, graph databases, and document stores. You need all three, but combining them is complex and fragile.
**Brainy solved the impossible:** One API. All three paradigms. Any scale.
Like HTTP standardized web communication, **Brainy standardizes knowledge representation.** One protocol that any AI model understands. One system that scales from prototype to planet.

## 📝 Adding Data
### Adding Single Entities
**Use `brainy.add()` when:**
- Adding one entity at a time
- You need the ID immediately for further operations
- Working with user input or real-time data
```typescript
// ✅ Perfect for single entities
const id = await brainy.add({
data: "New research paper on quantum computing",
type: NounType.Document,
metadata: { category: "research", priority: "high" }
})
```
**Decision factors:**
- **Single item?** → `add()`
- **Need immediate ID?** → `add()`
- **Interactive application?** → `add()`
### Adding Multiple Entities
**Use `brainy.addMany()` when:**
- Bulk importing data
- Processing batches (>10 items)
- Performance is critical
```typescript
// ✅ Perfect for bulk operations
const result = await brainy.addMany({
items: documents.map(doc => ({
data: doc.content,
type: NounType.Document,
metadata: doc.metadata
})),
chunkSize: 100,
parallel: true
})
```
**Decision factors:**
- **Multiple items (>10)?** → `addMany()`
- **Batch processing?** → `addMany()`
- **Can tolerate some failures?** → `addMany()` with `continueOnError: true`
### Streaming Data
**Use Streaming Pipeline when:**
- Real-time data ingestion
- Processing large datasets that don't fit in memory
- Need transformation during ingestion
```typescript
// ✅ Perfect for streaming
const pipeline = brainy.streaming.pipeline()
.transform(data => ({ ...data, processed: true }))
.batch(50)
.into(brainy)
```
---
## 🔍 Finding Data
### Natural Language Search
**Use `brainy.find("query string")` when:**
- User is typing search queries
- You want semantic understanding
- Building search interfaces
```typescript
// ✅ Perfect for user searches
const results = await brainy.find("documents about machine learning")
```
**Decision factors:**
- **User-generated query?** → Natural language `find()`
- **Semantic understanding needed?** → Natural language `find()`
- **Search interface?** → Natural language `find()`
### Structured Search
**Use `brainy.find({ query, where, type })` when:**
- Complex filtering requirements
- Combining text search with metadata filters
- Performance-critical searches
```typescript
// ✅ Perfect for complex queries
const results = await brainy.find({
query: "neural networks",
type: NounType.Document,
where: {
status: "published",
year: { $gte: 2020 }
},
limit: 20
})
```
**Decision factors:**
- **Need metadata filtering?** → Structured `find()`
- **Performance critical?** → Structured `find()`
- **Complex criteria?** → Structured `find()`
### Similarity Search
**Use `brainy.similar()` when:**
- Finding "more like this" content
- Recommendation systems
- Duplicate detection
```typescript
// ✅ Perfect for recommendations
const similar = await brainy.similar({
to: "document-id-123",
limit: 10,
type: NounType.Document
})
```
**Decision factors:**
- **"More like this" feature?** → `similar()`
- **Recommendations?** → `similar()`
- **Duplicate detection?** → `similar()`
### Retrieval by ID
**Use `brainy.get()` when:**
- You know the exact ID
- Loading specific entities
- Following relationships
```typescript
// ✅ Perfect for direct access
const entity = await brainy.get("known-id-123")
```
**Decision factors:**
- **Known ID?** → `get()`
- **Direct access needed?** → `get()`
- **Following relationships?** → `get()`
---
## 🔗 Relationships
### Creating Relationships
**Use `brainy.relate()` when:**
- Connecting two entities
- Building knowledge graphs
- Modeling real-world relationships
```typescript
// ✅ Perfect for connections
await brainy.relate({
from: "user-123",
to: "project-456",
type: VerbType.WorksOn,
metadata: { role: "lead", since: "2024-01-01" }
})
```
**Decision factors:**
- **Connecting entities?** → `relate()`
- **Need relationship metadata?** → `relate()`
- **Building graphs?** → `relate()`
### Querying Relationships
**Use `brainy.getRelations()` when:**
- Finding all connections for an entity
- Exploring relationship patterns
- Building relationship views
```typescript
// ✅ Perfect for relationship queries
const relations = await brainy.getRelations({
from: "user-123",
type: VerbType.WorksOn
})
```
---
## 📁 File Operations
### Basic File Operations
**Use VFS when:**
- Managing files and directories
- Need hierarchical structure
- Building file explorers
```typescript
// ✅ Perfect for file management
const vfs = brainy.vfs({ storage: 'filesystem' })
await vfs.writeFile('/docs/readme.md', 'content')
const files = await vfs.getDirectChildren('/docs')
```
**Decision factors:**
- **File management?** → VFS
- **Directory structure?** → VFS
- **File explorer interface?** → VFS
### Intelligent File Management
**Use VFS (Semantic VFS) when:**
- Need semantic file search
- Want AI-powered concept extraction
- Building smart file systems
- Require multi-dimensional file access
```typescript
// ✅ Perfect for intelligent file systems
const knowledgeVFS = await vfs.withKnowledge(brainy)
const insights = await knowledgeVFS.getFileInsights('/project')
```
---
## 🧠 AI Analysis
### Clustering
**Use Neural API clustering when:**
- Discovering data patterns
- Organizing large datasets
- Creating automatic categories
```typescript
// ✅ Perfect for pattern discovery
const neural = brainy.neural()
const clusters = await neural.cluster({
entities: entityIds,
k: 5,
method: 'hierarchical'
})
```
### Intelligence Systems
**Use Triple Intelligence when:**
- Complex multi-criteria searches
- Advanced relationship queries
- Performance-critical operations
```typescript
// ✅ Perfect for complex queries
const intelligence = brainy.getTripleIntelligence()
const results = await intelligence.query({
vector: queryVector,
metadata: { category: 'research' },
graph: { connected: 'user-123' }
})
```
---
## 🚀 Performance Optimization Guide
### When Performance Matters
| Scenario | Best Choice | Why |
|----------|-------------|-----|
| **Bulk Import** | `addMany()` | Batched operations, parallel processing |
| **Metadata-only Search** | `find({ where: {...} })` | Skips vector computation |
| **Known ID Access** | `get()` | Direct index lookup |
| **Large Result Sets** | Pagination with `offset`/`limit` | Memory efficient |
| **Real-time Streams** | Streaming Pipeline | Memory efficient, scalable |
### Memory Usage Optimization
```typescript
// ❌ Memory intensive
const allResults = await brainy.find({ limit: 10000 })
// ✅ Memory efficient
for (let offset = 0; offset < total; offset += 100) {
const batch = await brainy.find({
query: "...",
limit: 100,
offset
})
await processBatch(batch)
}
```
---
## 🎯 Common Use Case Patterns
### Building a Search Interface
```typescript
// User types query → Natural language search
const searchResults = await brainy.find(userQuery)
// User applies filters → Structured search
const filteredResults = await brainy.find({
query: userQuery,
where: selectedFilters,
type: selectedTypes
})
// User clicks "more like this" → Similarity search
const similar = await brainy.similar({ to: selectedId })
```
### Building a Recommendation System
```typescript
// 1. Get user's interaction history
const user = await brainy.get(userId)
// 2. Find similar users
const similarUsers = await brainy.similar({ to: userId, type: NounType.Person })
// 3. Get their liked content
const recommendations = []
for (const similarUser of similarUsers) {
const relations = await brainy.getRelations({
from: similarUser.id,
type: VerbType.Likes
})
recommendations.push(...relations)
}
```
### Building a Knowledge Graph
```typescript
// 1. Add entities
const entities = await Promise.all([
brainy.add({ data: "Person: Alice", type: NounType.Person }),
brainy.add({ data: "Company: TechCorp", type: NounType.Organization }),
brainy.add({ data: "Project: AI Assistant", type: NounType.Thing })
])
// 2. Create relationships
await brainy.relate({
from: entities[0], // Alice
to: entities[1], // TechCorp
type: VerbType.WorksFor
})
await brainy.relate({
from: entities[0], // Alice
to: entities[2], // AI Assistant
type: VerbType.WorksOn
})
// 3. Query the graph
const aliceConnections = await brainy.getRelations({ from: entities[0] })
```

# 🧠 Core API Patterns: Modern Brainy v3.x
> Learn the correct patterns for Brainy's core operations. Avoid v2.x confusion and use modern, efficient APIs.
## 🚨 Critical: Use v3.x APIs Only
### ❌ **WRONG - Deprecated v2.x APIs**
```typescript
// DON'T DO THIS - These methods don't exist in v3.x!
await brain.addNoun(text, type, metadata) // ❌ Removed
await brain.getNouns({ pagination }) // ❌ Removed
await brain.addVerb(source, target, type) // ❌ Removed
await brain.getVerbs() // ❌ Removed
await brain.deleteNoun(id) // ❌ Removed
await brain.deleteVerb(id) // ❌ Removed
```
### ✅ **CORRECT - Modern v3.x APIs**
```typescript
// ✅ Use these modern methods instead
await brain.add({ data, type, metadata }) // Modern unified add
await brain.find({ limit: 100 }) // Natural language search
await brain.relate({ from, to, type }) // Clean relationship creation
await brain.getRelations() // Modern relationship queries
await brain.delete(id) // Unified deletion
// Relationships auto-cascade when entities are deleted
```
## 📋 Entity Management Patterns
### ❌ **WRONG - v2.x Style**
```typescript
// DON'T DO THIS - Old API patterns
import { Brainy } from 'old-brainy' // ❌ Wrong import
const brain = new Brainy({ // ❌ Old class name
complexConfig: true
})
const id = await brain.addNoun( // ❌ Deprecated method
"John Smith is a developer",
"Person",
{ role: "engineer" }
)
```
### ✅ **CORRECT - Modern Patterns**
```typescript
// ✅ Pattern 1: Basic entity creation
import { Brainy, NounType } from '@soulcraft/brainy'
const brain = new Brainy() // ✅ Zero config
await brain.init()
const id = await brain.add({
data: "John Smith is a developer",
type: NounType.Person,
metadata: { role: "engineer", team: "backend" }
})
// ✅ Pattern 2: Bulk entity creation
const entities = [
{ data: "React framework", type: NounType.Technology },
{ data: "Vue.js framework", type: NounType.Technology },
{ data: "Angular framework", type: NounType.Technology }
]
const ids = await Promise.all(
entities.map(entity => brain.add(entity))
)
// ✅ Pattern 3: Entity with pre-computed vector
const customVector = await brain.embed("Custom text")
const vectorId = await brain.add({
data: "Optimized content",
type: NounType.Document,
vector: customVector, // Skip re-embedding
metadata: { source: "api", optimized: true }
})
```
## 🔍 Search & Discovery Patterns
### ❌ **WRONG - Confusing Old Patterns**
```typescript
// DON'T DO THIS - Mixing old and new APIs
const results1 = await brain.searchText("query") // ❌ Old method
const results2 = await brain.getNouns({ filter }) // ❌ Doesn't exist
const results3 = await brain.findSimilar(text) // ❌ Unclear naming
```
### ✅ **CORRECT - Clean Search Patterns**
```typescript
// ✅ Pattern 1: Natural language search
const results = await brain.find("React developers working on authentication")
// ✅ Pattern 2: Structured search with filters
const filteredResults = await brain.find({
like: "machine learning", // Vector similarity
where: { // Metadata filtering
type: NounType.Document,
year: { $gte: 2020 },
status: "published"
},
limit: 50,
orderBy: 'relevance'
})
// ✅ Pattern 3: Similarity search
const similarItems = await brain.similar({
to: existingEntityId, // Find items similar to this
threshold: 0.8, // Minimum similarity
limit: 10,
exclude: [existingEntityId] // Don't include the source
})
// ✅ Pattern 4: Advanced search with relationships
const connectedResults = await brain.find({
like: "frontend frameworks",
connected: {
to: reactId, // Connected to React
via: "related-to", // Through this relationship
depth: 2 // Up to 2 hops away
}
})
```
## 🔗 Relationship Patterns
### ❌ **WRONG - Old Relationship APIs**
```typescript
// DON'T DO THIS - Old relationship patterns
await brain.addVerb(sourceId, targetId, "uses", { strength: 0.9 }) // ❌ Old API
const verbs = await brain.getVerbsBySource(sourceId) // ❌ Removed
await brain.deleteVerb(verbId) // ❌ Old pattern
```
### ✅ **CORRECT - Modern Relationship Management**
```typescript
// ✅ Pattern 1: Create relationships
const relationId = await brain.relate({
from: developerId,
to: frameworkId,
type: VerbType.Uses,
metadata: {
since: "2023-01-01",
proficiency: "expert",
hours_per_week: 40
}
})
// ✅ Pattern 2: Query relationships
const relationships = await brain.getRelations({
from: developerId, // Relationships from this entity
type: VerbType.Uses, // Of this type
limit: 100
})
// ✅ Pattern 3: Bidirectional relationships
await brain.relate({
from: projectId,
to: developerId,
type: VerbType.AssignedTo,
bidirectional: true, // Creates reverse relationship
metadata: { role: "lead", start_date: "2024-01-01" }
})
// ✅ Pattern 4: Relationship-based discovery
const collaborators = await brain.find({
connected: {
to: currentProjectId,
via: VerbType.WorksOn,
direction: "incoming" // Who works on this project
}
})
```
## 🗃️ Data Retrieval Patterns
### ❌ **WRONG - Inefficient Patterns**
```typescript
// DON'T DO THIS - Loading everything
const everything = await brain.getNouns({ limit: 1000000 }) // ❌ Crashes
const allData = await brain.exportAll() // ❌ Memory explosion
```
### ✅ **CORRECT - Efficient Data Access**
```typescript
// ✅ Pattern 1: Paginated retrieval
async function getAllEntitiesPaginated() {
const pageSize = 100
let offset = 0
let allEntities = []
while (true) {
const page = await brain.find({
limit: pageSize,
offset: offset
})
if (page.length === 0) break
allEntities.push(...page)
offset += pageSize
// Optional: Progress reporting
console.log(`Loaded ${allEntities.length} entities...`)
}
return allEntities
}
// ✅ Pattern 2: Streaming large datasets
async function* streamEntities() {
const pageSize = 50
let offset = 0
while (true) {
const page = await brain.find({
limit: pageSize,
offset: offset
})
if (page.length === 0) break
for (const entity of page) {
yield entity
}
offset += pageSize
}
}
// Usage
for await (const entity of streamEntities()) {
await processEntity(entity)
}
// ✅ Pattern 3: Specific entity retrieval
const entity = await brain.get(entityId)
if (entity) {
console.log('Entity data:', entity.data)
console.log('Metadata:', entity.metadata)
} else {
console.log('Entity not found')
}
```
## 🔄 Update & Delete Patterns
### ❌ **WRONG - Manual Update Patterns**
```typescript
// DON'T DO THIS - Recreating entities
await brain.delete(oldId)
const newId = await brain.add(updatedData) // ❌ Loses relationships
```
### ✅ **CORRECT - Update Operations**
```typescript
// ✅ Pattern 1: Update entity data
await brain.update(entityId, {
data: "Updated content here",
metadata: {
lastModified: Date.now(),
version: "2.0"
}
})
// ✅ Pattern 2: Partial metadata updates
await brain.updateMetadata(entityId, {
status: "published",
tags: ["important", "featured"]
// Merges with existing metadata
})
// ✅ Pattern 3: Safe deletion with cascade options
await brain.delete(entityId, {
cascade: true, // Delete related relationships
backup: true // Create backup before deletion
})
// ✅ Pattern 4: Bulk operations
const updateOperations = entities.map(entity => ({
id: entity.id,
changes: { status: "processed" }
}))
await brain.updateMany(updateOperations)
```
## 🧮 Vector & Embedding Patterns
### ❌ **WRONG - Manual Vector Handling**
```typescript
// DON'T DO THIS - Manual embedding without understanding
const vector = await brain.embed(text)
// Store vector somewhere manually // ❌ Missing integration
```
### ✅ **CORRECT - Smart Vector Operations**
```typescript
// ✅ Pattern 1: Automatic embedding (recommended)
const id = await brain.add({
data: "Content to be embedded",
type: NounType.Document
// Vector computed automatically
})
// ✅ Pattern 2: Pre-computed vectors for optimization
const texts = ["Text 1", "Text 2", "Text 3"]
const vectors = await Promise.all(
texts.map(text => brain.embed(text))
)
const entities = await Promise.all(
texts.map((text, i) => brain.add({
data: text,
type: NounType.Document,
vector: vectors[i] // Skip re-embedding
}))
)
// ✅ Pattern 3: Vector similarity search
const queryVector = await brain.embed("search query")
const similar = await brain.similar({
vector: queryVector, // Use vector directly
threshold: 0.75,
limit: 20
})
// ✅ Pattern 4: Compare vectors directly
const vector1 = await brain.embed("First text")
const vector2 = await brain.embed("Second text")
const similarity = brain.computeSimilarity(vector1, vector2)
console.log(`Similarity: ${similarity}`)
```
## 🏗️ Configuration Patterns
### ❌ **WRONG - Over-Configuration**
```typescript
// DON'T DO THIS - Complex configurations that break
const brain = new Brainy({
storage: {
type: 'complex',
options: {
nested: {
configuration: true,
that: "breaks"
}
}
},
embedding: {
customModel: "broken-model",
dimensions: 999999
}
})
```
### ✅ **CORRECT - Smart Configuration**
```typescript
// ✅ Pattern 1: Zero configuration (recommended)
const brain = new Brainy() // Auto-detects everything
await brain.init()
// ✅ Pattern 2: Simple storage selection
const fsBrain = new Brainy({
storage: { type: 'filesystem', path: './data' }
})
const cloudBrain = new Brainy({
storage: { type: 's3', bucket: 'my-data' }
})
// ✅ Pattern 3: Production configuration
const prodBrain = new Brainy({
storage: {
type: 's3',
bucket: process.env.BRAINY_BUCKET,
region: process.env.AWS_REGION
},
silent: true, // No console output
distributed: true, // Enable clustering
cache: { maxSize: 10000 } // Larger cache
})
// ✅ Pattern 4: Development vs production
const isDev = process.env.NODE_ENV === 'development'
const brain = new Brainy({
storage: isDev
? { type: 'memory' } // Fast for dev
: { type: 'filesystem', path: './brainy-data' }, // Persistent for prod
silent: !isDev, // Verbose in dev, quiet in prod
cache: { maxSize: isDev ? 100 : 5000 }
})
```
## 🔄 Migration from v2.x
### ✅ **Migration Patterns**
```typescript
// If you have old v2.x code, here's how to migrate:
// OLD v2.x:
// await brain.addNoun(text, type, metadata)
// NEW v3.x:
await brain.add({ data: text, type, metadata })
// OLD v2.x:
// await brain.getNouns({ pagination: { limit: 100 } })
// NEW v3.x:
await brain.find({ limit: 100 })
// OLD v2.x:
// await brain.addVerb(sourceId, targetId, verbType, metadata)
// NEW v3.x:
await brain.relate({ from: sourceId, to: targetId, type: verbType, metadata })
// OLD v2.x:
// await brain.searchText(query)
// NEW v3.x:
await brain.find(query) // More powerful natural language search
```
## 🚀 Performance Patterns
### ✅ **High-Performance Patterns**
```typescript
// ✅ Pattern 1: Batch operations
const entities = [/* large array */]
const batchSize = 100
for (let i = 0; i < entities.length; i += batchSize) {
const batch = entities.slice(i, i + batchSize)
await Promise.all(
batch.map(entity => brain.add(entity))
)
// Optional: Rate limiting
await new Promise(resolve => setTimeout(resolve, 100))
}
// ✅ Pattern 2: Connection pooling for distributed
const brain = new Brainy({
distributed: true,
connectionPool: {
min: 5,
max: 50,
acquireTimeoutMillis: 30000
}
})
// ✅ Pattern 3: Efficient caching
const brain = new Brainy({
cache: {
maxSize: 10000, // Number of items
ttl: 300000, // 5 minutes
updateAgeOnGet: true // LRU behavior
}
})
// ✅ Pattern 4: Memory-conscious operations
const results = await brain.find({
query: "large dataset query",
limit: 1000, // Reasonable limit
includeVectors: false // Exclude vectors if not needed
})
```
## 🛡️ Error Handling Patterns
### ✅ **Robust Error Handling**
```typescript
// ✅ Pattern 1: Specific error handling
try {
const result = await brain.add({ data, type, metadata })
return result
} catch (error) {
if (error.code === 'DUPLICATE_ENTITY') {
console.log('Entity already exists, updating instead...')
return await brain.update(error.existingId, { data, metadata })
} else if (error.code === 'STORAGE_FULL') {
throw new Error('Storage capacity exceeded')
} else if (error.code === 'EMBEDDING_FAILED') {
console.warn('Embedding failed, retrying with simpler text...')
return await brain.add({
data: data.substring(0, 1000), // Truncate
type,
metadata
})
}
throw error
}
// ✅ Pattern 2: Retry with exponential backoff
async function resilientAdd(data: any, maxRetries = 3) {
for (let attempt = 1; attempt <= maxRetries; attempt++) {
try {
return await brain.add(data)
} catch (error) {
if (attempt === maxRetries) throw error
const delay = Math.pow(2, attempt) * 1000
console.warn(`Attempt ${attempt} failed, retrying in ${delay}ms...`)
await new Promise(resolve => setTimeout(resolve, delay))
}
}
}
// ✅ Pattern 3: Graceful degradation
async function robustSearch(query: string) {
try {
// Try advanced semantic search first
return await brain.find({
like: query,
threshold: 0.8,
limit: 50
})
} catch (error) {
console.warn('Semantic search failed, falling back to basic search:', error.message)
try {
// Fallback to simple text search
return await brain.find(query)
} catch (fallbackError) {
console.error('All search methods failed:', fallbackError.message)
return [] // Return empty results rather than crash
}
}
}
```
## 📊 Monitoring Patterns
### ✅ **Production Monitoring**
```typescript
// ✅ Pattern 1: Performance monitoring
const startTime = Date.now()
const result = await brain.add(data)
const duration = Date.now() - startTime
if (duration > 1000) {
console.warn(`Slow add operation: ${duration}ms`)
}
// ✅ Pattern 2: Health checks
async function healthCheck() {
try {
// Test basic operations
const testId = await brain.add({
data: "health check",
type: NounType.System,
metadata: { test: true }
})
await brain.get(testId)
await brain.delete(testId)
return { status: 'healthy', timestamp: Date.now() }
} catch (error) {
return {
status: 'unhealthy',
error: error.message,
timestamp: Date.now()
}
}
}
// ✅ Pattern 3: Metrics collection
class BrainyMetrics {
private metrics = {
operations: 0,
errors: 0,
totalTime: 0
}
async timedOperation<T>(operation: () => Promise<T>): Promise<T> {
const start = Date.now()
try {
const result = await operation()
this.metrics.operations++
this.metrics.totalTime += Date.now() - start
return result
} catch (error) {
this.metrics.errors++
throw error
}
}
getStats() {
return {
...this.metrics,
avgTime: this.metrics.totalTime / this.metrics.operations || 0,
errorRate: this.metrics.errors / this.metrics.operations || 0
}
}
}
```

# Data Model
> How Brainy stores entities and relationships, and the critical distinction between `data` and `metadata`.
---
## Entity (Noun)
An entity is the fundamental data unit in Brainy. Every entity has:
| Field | Type | Indexed | Description |
|-------|------|---------|-------------|
| `id` | `string` | Primary key | UUID v4 (auto-generated or custom) |
| `data` | `any` | **HNSW vector index** | Content used for semantic/hybrid search. Strings auto-embed. |
| `metadata` | `object` | **MetadataIndex** | Structured queryable fields (tags, dates, flags, etc.) |
| `type` | `NounType` | MetadataIndex (as `noun`) | Entity type classification |
| `vector` | `number[]` | HNSW | 384-dim embedding (auto-computed from `data` or user-provided) |
| `confidence` | `number` | MetadataIndex | Type classification confidence (0-1) |
| `weight` | `number` | MetadataIndex | Entity importance/salience (0-1) |
| `service` | `string` | MetadataIndex | Multi-tenancy identifier |
| `createdAt` | `number` | MetadataIndex | Creation timestamp (ms since epoch) |
| `updatedAt` | `number` | MetadataIndex | Last update timestamp (ms since epoch) |
| `createdBy` | `object` | MetadataIndex | Source augmentation info |
### Example
```typescript
const id = await brain.add({
data: 'John Smith is a software engineer at Acme Corp', // → embedded into vector
type: NounType.Person,
metadata: { // → indexed, queryable via where filters
role: 'engineer',
department: 'backend',
yearsExperience: 8
},
confidence: 0.95,
weight: 0.7
})
```
---
## Relationship (Verb)
A relationship is a typed, directed edge connecting two entities.
| Field | Type | Indexed | Description |
|-------|------|---------|-------------|
| `id` | `string` | Primary key | UUID v4 (auto-generated) |
| `from` | `string` | **GraphAdjacencyIndex** | Source entity ID |
| `to` | `string` | **GraphAdjacencyIndex** | Target entity ID |
| `type` | `VerbType` | GraphAdjacencyIndex (as `verb`) | Relationship type classification |
| `data` | `any` | — | Opaque content (overrides auto-computed vector if provided) |
| `metadata` | `object` | — | Structured fields on the edge |
| `weight` | `number` | — | Connection strength (0-1, default: 1.0) |
| `confidence` | `number` | — | Relationship certainty (0-1) |
| `evidence` | `RelationEvidence` | — | Why this relationship was detected |
| `createdAt` | `number` | — | Creation timestamp (ms since epoch) |
| `updatedAt` | `number` | — | Last update timestamp (ms since epoch) |
| `service` | `string` | — | Multi-tenancy identifier |
### Example
```typescript
const relId = await brain.relate({
from: personId,
to: projectId,
type: VerbType.WorksOn,
data: 'Lead engineer on the AI module', // Optional: content for this edge
metadata: { // Optional: queryable edge fields
role: 'lead',
startDate: '2024-01-15'
},
weight: 0.9
})
```
---
## Data vs Metadata
This is the most important concept in Brainy's storage model:
### `data` — Content for Semantic Search
- Embedded into a 384-dimensional vector via the WASM embedding engine
- Searchable via **semantic similarity** (HNSW vector index) and **hybrid text+semantic** search
- Queried by passing `query` to `find()`:
```typescript
brain.find({ query: 'machine learning algorithms' })
```
- **NOT** indexed by MetadataIndex — you cannot use `where` filters on `data`
- Stored opaquely: strings, objects, numbers — anything goes
### `metadata` — Structured Queryable Fields
- Indexed by MetadataIndex with O(1) lookups per field
- Queryable via `where` filters using [BFO operators](./QUERY_OPERATORS.md):
```typescript
brain.find({
where: {
department: 'engineering',
yearsExperience: { greaterThan: 5 },
tags: { contains: 'senior' }
}
})
```
- **NOT** used for vector/semantic search
- Must be a flat or lightly nested object
### Quick Reference
| | `data` | `metadata` |
|---|---|---|
| **Purpose** | Content for embedding / semantic search | Structured fields for filtering |
| **Searched by** | `find({ query })` — vector similarity, hybrid text+semantic | `find({ where })` — exact, range, set operators |
| **Indexed by** | HNSW vector index | MetadataIndex |
| **Queryable with operators?** | No | Yes (`equals`, `greaterThan`, `oneOf`, etc.) |
| **Auto-embedded?** | Yes (strings → 384-dim vectors) | No |
| **Typical content** | Text descriptions, document content | Tags, dates, status flags, categories, numeric fields |
### Common Pattern
```typescript
// Add an article
await brain.add({
data: 'A deep dive into transformer architectures and attention mechanisms',
type: NounType.Document,
metadata: {
title: 'Transformer Deep Dive',
author: 'Dr. Chen',
publishedYear: 2024,
tags: ['AI', 'transformers', 'NLP'],
status: 'published'
}
})
// Search by content (semantic — searches data)
const results = await brain.find({ query: 'neural network attention' })
// Filter by fields (exact — queries metadata)
const recent = await brain.find({
where: {
publishedYear: { greaterThan: 2023 },
status: 'published'
}
})
// Combine both (Triple Intelligence)
const precise = await brain.find({
query: 'attention mechanisms', // Semantic search on data
where: { author: 'Dr. Chen' }, // Metadata filter
connected: { from: authorId, depth: 1 } // Graph traversal
})
```
---
## Storage Field Naming
Internally, Brainy uses different field names in storage vs the public API:
| Public API (Entity/Relation) | Storage (metadata object) | Notes |
|------------------------------|--------------------------|-------|
| `type` | `noun` | Entity type stored as `noun` |
| `from` | `sourceId` | Relationship source |
| `to` | `targetId` | Relationship target |
| `type` (on Relation) | `verb` | Relationship type stored as `verb` |
When querying with `find()`, you can use:
- `type` parameter (convenience alias, equivalent to `where.noun`)
- `where.noun` directly
```typescript
// These are equivalent:
brain.find({ type: NounType.Person })
brain.find({ where: { noun: NounType.Person } })
```
---
## Standard Metadata Fields
When you add an entity, Brainy stores these standard fields in the metadata object alongside your custom fields:
| Field | Set By | Description |
|-------|--------|-------------|
| `noun` | System | Entity type (NounType enum value) |
| `data` | System | The raw `data` value (stored opaquely) |
| `createdAt` | System | Creation timestamp |
| `updatedAt` | System | Last update timestamp |
| `confidence` | User | Type classification confidence |
| `weight` | User | Entity importance |
| `service` | User | Multi-tenancy identifier |
| `createdBy` | User/System | Source augmentation |
On read, these standard fields are extracted to top-level Entity properties. The `metadata` field on the returned Entity contains **only your custom fields**.

# Metadata Contract Implementation Plan
## New Required Interface
```typescript
export interface BrainyAugmentation {
// Identity
name: string
timing: 'before' | 'after' | 'around' | 'replace'
operations: string[]
priority: number
// REQUIRED metadata contract
metadata: 'none' | 'readonly' | MetadataAccess
// Methods
initialize(context: AugmentationContext): Promise<void>
execute<T = any>(operation: string, params: any, next: () => Promise<T>): Promise<T>
shouldExecute?(operation: string, params: any): boolean
shutdown?(): Promise<void>
}
interface MetadataAccess {
reads?: string[] | '*' // Fields to read, or '*' for all
writes?: string[] | '*' // Fields to write, or '*' for all
namespace?: string // Optional: custom namespace like '_myAug'
}
```
## Augmentation Analysis & Classification
### Category 1: No Metadata Access ('none')
These augmentations don't read or write metadata at all:
1. **CacheAugmentation** - Only caches search results
2. **RequestDeduplicatorAugmentation** - Only deduplicates requests
3. **ConnectionPoolAugmentation** - Only manages storage connections
4. **StorageAugmentation** - Base storage layer, metadata handled by Brainy
### Category 2: Read-Only Access ('readonly')
These augmentations read metadata but never modify it:
6. **IndexAugmentation** - Reads metadata to build indexes
7. **MonitoringAugmentation** - Reads metadata for monitoring
8. **MetricsAugmentation** - Reads metadata for metrics collection
9. **BatchProcessingAugmentation** - Reads metadata to check for external IDs
10. **EntityRegistryAugmentation** - Reads metadata to register entities
11. **AutoRegisterEntitiesAugmentation** - Reads metadata for auto-registration
12. **ConduitAugmentation** - Reads metadata to pass through operations
### Category 3: Metadata Writers (needs specific access)
These augmentations modify metadata and need specific field declarations:
13. **SynapseAugmentation** - Writes to '_synapse' field
```typescript
metadata: {
reads: '*',
writes: ['_synapse', '_synapseTimestamp'],
namespace: '_synapse' // Uses its own namespace
}
```
14. **IntelligentVerbScoringAugmentation** - Adds scoring to verbs
```typescript
metadata: {
reads: ['type', 'verb', 'source', 'target'],
writes: ['weight', 'confidence', 'intelligentScoring']
}
```
15. **ServerSearchAugmentation** - Might add server metadata
```typescript
metadata: {
reads: '*',
writes: ['_server', '_syncedAt']
}
```
16. **NeuralImportAugmentation** - Enriches imported data
```typescript
metadata: {
reads: '*',
writes: ['nounType', 'verbType', '_importedAt', '_enriched']
}
```
### Category 4: API/Server (needs analysis)
17. **ApiServerAugmentation** - Likely read-only for serving data
18. **StorageAugmentations** (plural) - Collection of storage implementations
19. **ConduitAugmentations** (plural) - Collection of conduit types
## Implementation Steps
### Phase 1: Update Base Interface
1. Update `BrainyAugmentation` interface to require `metadata` field
2. Update `BaseAugmentation` class to have abstract `metadata` property
3. Add runtime enforcement in augmentation executor
### Phase 2: Update Each Augmentation
For each augmentation, add the appropriate metadata declaration:
#### Example Updates:
**CacheAugmentation:**
```typescript
export class CacheAugmentation extends BaseAugmentation {
readonly name = 'cache'
readonly metadata = 'none' as const // ✅ No metadata access
// ... rest unchanged
}
```
```typescript
readonly metadata = 'readonly' as const // ✅ Only reads for logging
// ... rest unchanged
}
```
**SynapseAugmentation:**
```typescript
export abstract class SynapseAugmentation extends BaseAugmentation {
readonly name = 'synapse'
readonly metadata = {
reads: '*',
writes: ['_synapse', '_synapseTimestamp'],
namespace: '_synapse'
} as const
// ... rest unchanged
}
```
### Phase 3: Runtime Enforcement
Add a metadata access enforcer that:
1. Wraps metadata objects based on declared access
2. Throws errors if augmentation violates its contract
3. Logs warnings in development mode
```typescript
class MetadataEnforcer {
enforce(augmentation: BrainyAugmentation, metadata: any): any {
if (augmentation.metadata === 'none') {
return null // No access at all
}
if (augmentation.metadata === 'readonly') {
return Object.freeze(deepClone(metadata)) // Read-only copy
}
// For specific access, create proxy that validates
return new Proxy(metadata, {
set(target, prop, value) {
const access = augmentation.metadata as MetadataAccess
if (!access.writes?.includes(String(prop)) && access.writes !== '*') {
throw new Error(`Augmentation '${augmentation.name}' cannot write to field '${String(prop)}'`)
}
target[prop] = value
return true
}
})
}
}
```
## Benefits
1. **Type Safety** - TypeScript enforces metadata declaration
2. **Runtime Safety** - Violations caught immediately
3. **Documentation** - Contract shows exactly what each augmentation does
4. **Brain-cloud Ready** - Registry can validate augmentations
5. **Developer Friendly** - Most use simple 'none' or 'readonly'
## Migration Checklist
- [ ] Update BrainyAugmentation interface
- [ ] Update BaseAugmentation class
- [ ] Add MetadataEnforcer
- [ ] Update all 19 augmentations with metadata declarations
- [ ] Add tests for metadata enforcement
- [ ] Update documentation

# 🧠 Neural API Patterns: AI-Powered Intelligence
> Learn the correct patterns for Brainy's Neural API. Avoid performance pitfalls and use AI features effectively.
## 🚨 Critical: Access Neural APIs Correctly
### ❌ **WRONG - Outdated Access Patterns**
```typescript
// DON'T DO THIS - Outdated documentation patterns
import { Brainy } from '@soulcraft/brainy' // ❌ Wrong import
const brain = new Brainy() // ❌ Old class name
// These may not work as expected:
const neural = brain.neural // ❌ May be undefined
```
### ✅ **CORRECT - Modern Neural Access**
```typescript
// ✅ Use modern Brainy class
import { Brainy } from '@soulcraft/brainy'
const brain = new Brainy()
await brain.init()
// ✅ Neural API is available after initialization
const clusters = await brain.neural.clusters()
const similarity = await brain.neural.similar('item1', 'item2')
```
## 🔍 Similarity Analysis Patterns
### ❌ **WRONG - Inefficient Similarity Checks**
```typescript
// DON'T DO THIS - N² comparisons
const items = await brain.find({ limit: 1000 })
const similarities = []
for (const item1 of items) {
for (const item2 of items) {
if (item1.id !== item2.id) {
const sim = await brain.neural.similar(item1.id, item2.id) // ❌ Millions of calls
similarities.push({ from: item1.id, to: item2.id, score: sim })
}
}
}
```
### ✅ **CORRECT - Efficient Similarity Patterns**
```typescript
// ✅ Pattern 1: Find neighbors (much more efficient)
const item = await brain.get('target-item-id')
const neighbors = await brain.neural.neighbors(item.id, {
limit: 10, // Top 10 most similar
threshold: 0.7, // Minimum similarity
includeScores: true // Include similarity scores
})
console.log(`Found ${neighbors.length} similar items`)
// ✅ Pattern 2: Batch similarity for specific pairs
const itemPairs = [
['item1', 'item2'],
['item1', 'item3'],
['item2', 'item3']
]
const similarities = await Promise.all(
itemPairs.map(async ([a, b]) => ({
from: a,
to: b,
score: await brain.neural.similar(a, b)
}))
)
// ✅ Pattern 3: Text-to-text similarity (no need for IDs)
const textSimilarity = await brain.neural.similar(
"Machine learning is fascinating",
"AI and deep learning are interesting",
{ detailed: true } // Get explanation of similarity
)
console.log(`Similarity: ${textSimilarity.score}`)
console.log(`Explanation: ${textSimilarity.explanation}`)
// ✅ Pattern 4: Vector-level similarity for optimization
const vector1 = await brain.embed("First concept")
const vector2 = await brain.embed("Second concept")
const vectorSimilarity = await brain.neural.similar(vector1, vector2)
```
## 🎯 Clustering Patterns
### ❌ **WRONG - Uncontrolled Clustering**
```typescript
// DON'T DO THIS - Clustering everything without limits
const everything = await brain.find({ limit: 100000 }) // ❌ Too much data
const clusters = await brain.neural.clusters() // ❌ May crash or timeout
```
### ✅ **CORRECT - Smart Clustering Patterns**
```typescript
// ✅ Pattern 1: Controlled clustering with limits
const recentItems = await brain.find({
where: {
createdAt: { $gte: Date.now() - 30 * 24 * 60 * 60 * 1000 } // Last 30 days
},
limit: 1000 // Reasonable limit
})
const clusters = await brain.neural.clusters(
recentItems.map(item => item.id),
{
algorithm: 'kmeans', // Reliable algorithm
maxClusters: 10, // Reasonable number
threshold: 0.75, // High similarity required
iterations: 50 // Convergence limit
}
)
// ✅ Pattern 2: Domain-specific clustering
const techDocs = await brain.find({
where: { category: 'technology', type: 'document' },
limit: 500
})
const techClusters = await brain.neural.clusterByDomain(
'category', // Group by this field
{
items: techDocs.map(doc => doc.id),
minClusterSize: 3, // Minimum items per cluster
maxClusters: 8
}
)
// ✅ Pattern 3: Temporal clustering for time-series data
const timebasedClusters = await brain.neural.clusterByTime(
'createdAt', // Time field
'week', // Time window (hour, day, week, month)
{
items: recentItems.map(item => item.id),
overlap: 0.2, // 20% overlap between windows
minPerWindow: 5 // Minimum items per time window
}
)
// ✅ Pattern 4: Streaming clustering for large datasets
async function clusterLargeDataset() {
const clusterStream = brain.neural.clusterStream({
batchSize: 100, // Process 100 items at a time
updateInterval: 1000, // Update clusters every 1000 items
maxMemory: 512 * 1024 * 1024 // 512MB memory limit
})
const allClusters = []
for await (const batch of clusterStream) {
console.log(`Processed ${batch.processed} items, found ${batch.clusters.length} clusters`)
allClusters.push(...batch.clusters)
}
return allClusters
}
```
## 🔍 Neighbor Discovery Patterns
### ❌ **WRONG - Manual Similarity Searches**
```typescript
// DON'T DO THIS - Reinventing neighbor search
async function findSimilarManually(targetId: string) {
const allItems = await brain.find({ limit: 10000 }) // ❌ Load everything
const similarities = []
for (const item of allItems) {
if (item.id !== targetId) {
const score = await brain.neural.similar(targetId, item.id) // ❌ Slow
if (score > 0.7) {
similarities.push({ id: item.id, score })
}
}
}
return similarities.sort((a, b) => b.score - a.score).slice(0, 10) // ❌ Inefficient
}
```
### ✅ **CORRECT - Optimized Neighbor Patterns**
```typescript
// ✅ Pattern 1: Basic neighbor search
const neighbors = await brain.neural.neighbors('target-item-id', {
limit: 20, // Top 20 neighbors
threshold: 0.6, // Minimum similarity
includeMetadata: true, // Include item metadata
includeDistances: true // Include exact similarity scores
})
// ✅ Pattern 2: Filtered neighbor search
const filteredNeighbors = await brain.neural.neighbors('article-id', {
limit: 10,
filter: {
type: 'document', // Only find similar documents
status: 'published', // Only published content
language: 'en' // Only English content
},
excludeIds: ['self-id', 'duplicate-id'] // Exclude specific items
})
// ✅ Pattern 3: Multi-level neighbor discovery
async function discoverNeighborNetwork(rootId: string, maxDepth = 2) {
const network = new Map()
const visited = new Set()
const queue = [{ id: rootId, depth: 0 }]
while (queue.length > 0) {
const { id, depth } = queue.shift()!
if (visited.has(id) || depth >= maxDepth) continue
visited.add(id)
const neighbors = await brain.neural.neighbors(id, {
limit: 5,
threshold: 0.8
})
network.set(id, neighbors)
// Add neighbors to queue for next depth level
if (depth < maxDepth - 1) {
neighbors.forEach(neighbor => {
queue.push({ id: neighbor.id, depth: depth + 1 })
})
}
}
return network
}
// ✅ Pattern 4: Recommendation engine
async function getRecommendations(userId: string) {
// Get user's liked items
const userItems = await brain.find({
connected: { to: userId, via: 'liked-by' }
})
// Find neighbors for each liked item
const allNeighbors = await Promise.all(
userItems.map(item =>
brain.neural.neighbors(item.id, {
limit: 10,
threshold: 0.7,
excludeConnected: { to: userId, via: 'liked-by' } // Exclude already liked
})
)
)
// Aggregate and rank recommendations
const recommendations = new Map()
allNeighbors.flat().forEach(neighbor => {
const current = recommendations.get(neighbor.id) || { score: 0, count: 0 }
current.score += neighbor.score
current.count += 1
recommendations.set(neighbor.id, current)
})
// Return top recommendations by average score
return Array.from(recommendations.entries())
.map(([id, stats]) => ({
id,
avgScore: stats.score / stats.count,
mentions: stats.count
}))
.sort((a, b) => b.avgScore - a.avgScore)
.slice(0, 10)
}
```
## 🏗️ Hierarchy & Structure Patterns
### ❌ **WRONG - Manual Hierarchy Building**
```typescript
// DON'T DO THIS - Building hierarchies manually
async function buildHierarchyManually(rootId: string) {
const root = await brain.get(rootId)
const allItems = await brain.find({ limit: 1000 }) // ❌ Load everything
// Manual tree building with nested loops
const hierarchy = { root, children: [] }
// ... complex manual logic
}
```
### ✅ **CORRECT - Semantic Hierarchy Patterns**
```typescript
// ✅ Pattern 1: Automatic semantic hierarchy
const hierarchy = await brain.neural.hierarchy('root-concept-id', {
maxDepth: 4, // Maximum tree depth
minSimilarity: 0.6, // Minimum similarity for inclusion
branchingFactor: 5, // Maximum children per node
algorithm: 'semantic' // Use semantic clustering
})
// ✅ Pattern 2: Domain-specific hierarchy
const techHierarchy = await brain.neural.hierarchy('technology-id', {
filter: { category: 'technology' },
weights: {
semantic: 0.7, // 70% based on content similarity
metadata: 0.3 // 30% based on metadata similarity
},
includeMetrics: true // Include hierarchy quality metrics
})
// ✅ Pattern 3: Multi-root hierarchy for complex domains
async function buildMultiRootHierarchy(rootIds: string[]) {
const hierarchies = await Promise.all(
rootIds.map(rootId =>
brain.neural.hierarchy(rootId, {
maxDepth: 3,
crossReference: true // Allow cross-hierarchy connections
})
)
)
// Merge hierarchies and find connections
const merged = {
roots: hierarchies,
connections: await findCrossHierarchyConnections(hierarchies)
}
return merged
}
async function findCrossHierarchyConnections(hierarchies: any[]) {
const connections = []
for (let i = 0; i < hierarchies.length; i++) {
for (let j = i + 1; j < hierarchies.length; j++) {
const leafNodes1 = extractLeafNodes(hierarchies[i])
const leafNodes2 = extractLeafNodes(hierarchies[j])
// Find connections between leaf nodes of different hierarchies
for (const leaf1 of leafNodes1) {
const neighbors = await brain.neural.neighbors(leaf1.id, {
limit: 5,
threshold: 0.8,
filter: { id: { $in: leafNodes2.map(l => l.id) } }
})
connections.push(...neighbors.map(n => ({
from: leaf1.id,
to: n.id,
hierarchyPair: [i, j],
similarity: n.score
})))
}
}
}
return connections
}
```
## 🚨 Outlier Detection Patterns
### ❌ **WRONG - Manual Outlier Detection**
```typescript
// DON'T DO THIS - Manual statistical outlier detection
async function findOutliersManually() {
const items = await brain.find({ limit: 1000 })
const similarities = []
// Calculate average similarity for each item (expensive)
for (const item of items) {
let totalSim = 0
let count = 0
for (const other of items) {
if (item.id !== other.id) {
totalSim += await brain.neural.similar(item.id, other.id) // ❌ N² operations
count++
}
}
similarities.push({ id: item.id, avgSimilarity: totalSim / count })
}
// Manual outlier calculation
const threshold = calculateManualThreshold(similarities) // ❌ Complex statistics
return similarities.filter(s => s.avgSimilarity < threshold)
}
```
### ✅ **CORRECT - AI-Powered Outlier Detection**
```typescript
// ✅ Pattern 1: Automatic outlier detection
const outliers = await brain.neural.outliers({
threshold: 0.3, // Items with < 30% avg similarity to others
method: 'isolation-forest', // AI-based outlier detection
contamination: 0.1, // Expect ~10% outliers
includeReasons: true // Explain why each item is an outlier
})
console.log(`Found ${outliers.length} outliers`)
outliers.forEach(outlier => {
console.log(`Outlier: ${outlier.id}, Score: ${outlier.score}`)
console.log(`Reason: ${outlier.reason}`)
})
// ✅ Pattern 2: Domain-specific outlier detection
const techOutliers = await brain.neural.outliers({
filter: { category: 'technology' },
features: ['content', 'metadata.tags', 'metadata.complexity'],
method: 'local-outlier-factor',
neighbors: 20 // Consider 20 nearest neighbors
})
// ✅ Pattern 3: Temporal outlier detection
const recentOutliers = await brain.neural.outliers({
timeWindow: '7days', // Look at last 7 days
baseline: '30days', // Compare to 30-day baseline
method: 'statistical', // Use statistical methods
autoThreshold: true // Automatically determine threshold
})
// ✅ Pattern 4: Streaming outlier detection
async function detectOutliersInStream() {
const outlierStream = brain.neural.outlierStream({
batchSize: 50,
updateInterval: 100, // Check every 100 new items
adaptiveThreshold: true // Threshold adapts as data changes
})
for await (const batch of outlierStream) {
console.log(`Batch ${batch.batchNumber}: ${batch.outliers.length} outliers detected`)
// Process outliers immediately
for (const outlier of batch.outliers) {
await handleOutlier(outlier)
}
}
}
async function handleOutlier(outlier: any) {
// Flag for manual review
await brain.update(outlier.id, {
metadata: {
flagged: true,
outlierScore: outlier.score,
outlierReason: outlier.reason,
flaggedAt: Date.now()
}
})
}
```
## 📊 Visualization Patterns
### ❌ **WRONG - Manual Visualization Data Preparation**
```typescript
// DON'T DO THIS - Manual coordinate calculation
async function prepareVisualizationManually() {
const items = await brain.find({ limit: 500 })
const coordinates = []
// Manual dimensionality reduction (complex math)
for (const item of items) {
const vector = await brain.embed(item.data)
// Complex PCA/t-SNE calculations manually
const x = complexMathFunction(vector) // ❌ Error-prone
const y = anotherComplexFunction(vector)
coordinates.push({ id: item.id, x, y })
}
return coordinates
}
```
### ✅ **CORRECT - AI-Powered Visualization**
```typescript
// ✅ Pattern 1: Automatic 2D visualization
const visualization = await brain.neural.visualize({
dimensions: 2, // 2D plot
algorithm: 'umap', // UMAP for better clustering preservation
maxItems: 1000, // Performance limit
includeMetadata: true, // Include item metadata in output
colorBy: 'cluster' // Color points by cluster membership
})
// Result format:
// {
// points: [{ id, x, y, cluster, metadata }, ...],
// clusters: [{ id, centroid: [x, y], members: [...] }, ...],
// stats: { stress, kruskalStress, trustworthiness }
// }
// ✅ Pattern 2: 3D visualization for complex data
const viz3D = await brain.neural.visualize({
dimensions: 3,
algorithm: 'tsne',
perplexity: 30, // t-SNE parameter
learningRate: 200, // t-SNE learning rate
iterations: 1000 // Number of optimization steps
})
// ✅ Pattern 3: Interactive visualization with filtering
const interactiveViz = await brain.neural.visualize({
filter: {
type: 'document',
createdAt: { $gte: Date.now() - 7 * 24 * 60 * 60 * 1000 }
},
groupBy: 'category', // Group points by metadata field
showLabels: true, // Include text labels
labelField: 'title', // Field to use for labels
includeEdges: true, // Show connections between similar items
edgeThreshold: 0.8 // Only show high-similarity connections
})
// ✅ Pattern 4: Real-time visualization updates
class LiveVisualization {
private visualization: any = null
private updateInterval: NodeJS.Timeout | null = null
async start() {
// Initial visualization
this.visualization = await brain.neural.visualize({
dimensions: 2,
algorithm: 'umap',
maxItems: 500,
includeMetadata: true
})
// Update every 30 seconds
this.updateInterval = setInterval(async () => {
await this.update()
}, 30000)
}
async update() {
// Get recent items
const recentItems = await brain.find({
where: {
createdAt: { $gte: Date.now() - 30000 } // Last 30 seconds
},
limit: 50
})
if (recentItems.length > 0) {
// Incrementally update visualization
const updates = await brain.neural.updateVisualization(
this.visualization.id,
{
newItems: recentItems.map(item => item.id),
algorithm: 'incremental' // Faster incremental updates
}
)
this.visualization = { ...this.visualization, ...updates }
this.onUpdate(updates)
}
}
onUpdate(updates: any) {
// Emit updates to frontend
console.log(`Visualization updated: ${updates.newPoints.length} new points`)
}
stop() {
if (this.updateInterval) {
clearInterval(this.updateInterval)
}
}
}
```
## 🚀 Performance Optimization Patterns
### ✅ **High-Performance Neural Operations**
```typescript
// ✅ Pattern 1: Batch processing for similarity
async function batchSimilarityCalculation(itemPairs: Array<[string, string]>) {
const batchSize = 100
const results = []
for (let i = 0; i < itemPairs.length; i += batchSize) {
const batch = itemPairs.slice(i, i + batchSize)
const batchResults = await Promise.all(
batch.map(async ([a, b]) => ({
from: a,
to: b,
similarity: await brain.neural.similar(a, b)
}))
)
results.push(...batchResults)
// Progress reporting
console.log(`Processed ${Math.min(i + batchSize, itemPairs.length)}/${itemPairs.length} pairs`)
}
return results
}
// ✅ Pattern 2: Caching expensive operations
class NeuralCache {
private clusterCache = new Map()
private similarityCache = new Map()
private readonly TTL = 5 * 60 * 1000 // 5 minutes
async getClusters(options: any) {
const key = JSON.stringify(options)
const cached = this.clusterCache.get(key)
if (cached && Date.now() - cached.timestamp < this.TTL) {
return cached.data
}
const clusters = await brain.neural.clusters(undefined, options)
this.clusterCache.set(key, {
data: clusters,
timestamp: Date.now()
})
return clusters
}
async getSimilarity(id1: string, id2: string) {
// Create consistent cache key regardless of order
const key = [id1, id2].sort().join('-')
const cached = this.similarityCache.get(key)
if (cached && Date.now() - cached.timestamp < this.TTL) {
return cached.data
}
const similarity = await brain.neural.similar(id1, id2)
this.similarityCache.set(key, {
data: similarity,
timestamp: Date.now()
})
return similarity
}
}
// ✅ Pattern 3: Memory-efficient streaming
async function processLargeDatasetEfficiently() {
const stream = brain.neural.clusterStream({
batchSize: 50, // Small batches for memory efficiency
maxMemoryMB: 256, // Memory limit
diskCache: true, // Use disk for temporary storage
compression: true // Compress cached data
})
const results = []
let totalProcessed = 0
for await (const batch of stream) {
// Process batch immediately, don't accumulate in memory
const processedBatch = await processBatch(batch)
// Save to disk or send to another service
await saveBatchToDisk(processedBatch)
totalProcessed += batch.items.length
console.log(`Processed ${totalProcessed} items`)
// Clear memory
batch.items = null
}
return { totalProcessed }
}
// ✅ Pattern 4: Parallel processing with worker threads
async function parallelNeuralProcessing(items: string[]) {
const numWorkers = require('os').cpus().length
const batchSize = Math.ceil(items.length / numWorkers)
const workers = []
for (let i = 0; i < numWorkers; i++) {
const batch = items.slice(i * batchSize, (i + 1) * batchSize)
if (batch.length > 0) {
workers.push(processWorkerBatch(batch))
}
}
const results = await Promise.all(workers)
return results.flat()
}
async function processWorkerBatch(batch: string[]) {
// This would run in a worker thread in real implementation
return Promise.all(
batch.map(async itemId => {
const neighbors = await brain.neural.neighbors(itemId, { limit: 5 })
return { itemId, neighbors }
})
)
}
```

# Query Operators (BFO)
> Brainy Field Operators — the complete reference for `where` filters in `find()`.
All operators work with `find({ where: { ... } })` and filter on **metadata fields** (not `data`).
---
## Equality
| Operator | Alias | Description | Example |
|----------|-------|-------------|---------|
| `equals` | `eq`, `is` | Exact match | `{ status: { equals: 'active' } }` |
| `notEquals` | `ne`, `isNot` | Not equal | `{ status: { notEquals: 'deleted' } }` |
**Shorthand:** A bare value is treated as `equals`:
```typescript
// These are equivalent:
brain.find({ where: { status: 'active' } })
brain.find({ where: { status: { equals: 'active' } } })
```
---
## Comparison
| Operator | Alias | Description | Example |
|----------|-------|-------------|---------|
| `greaterThan` | `gt` | Greater than | `{ age: { greaterThan: 18 } }` |
| `greaterEqual` | `gte` | Greater or equal | `{ score: { greaterEqual: 90 } }` |
| `lessThan` | `lt` | Less than | `{ price: { lessThan: 100 } }` |
| `lessEqual` | `lte` | Less or equal | `{ rating: { lessEqual: 3 } }` |
| `between` | — | Inclusive range `[min, max]` | `{ year: { between: [2020, 2025] } }` |
```typescript
// Range query
const recent = await brain.find({
where: {
createdAt: { between: [Date.now() - 86400000, Date.now()] }
}
})
```
---
## Array / Set
| Operator | Alias | Description | Example |
|----------|-------|-------------|---------|
| `oneOf` | `in` | Value is one of the given options | `{ color: { oneOf: ['red', 'blue'] } }` |
| `noneOf` | — | Value is NOT one of the given options | `{ status: { noneOf: ['deleted', 'archived'] } }` |
| `contains` | — | Array field contains value | `{ tags: { contains: 'ai' } }` |
| `excludes` | — | Array field does NOT contain value | `{ tags: { excludes: 'spam' } }` |
| `hasAll` | — | Array field contains ALL listed values | `{ skills: { hasAll: ['js', 'ts'] } }` |
```typescript
// Find entities tagged with 'ai'
const aiEntities = await brain.find({
where: { tags: { contains: 'ai' } }
})
// Find entities of specific types
const people = await brain.find({
where: { noun: { oneOf: ['Person', 'Agent'] } }
})
```
---
## Existence
| Operator | Description | Example |
|----------|-------------|---------|
| `exists: true` | Field exists (has any value) | `{ email: { exists: true } }` |
| `exists: false` | Field does NOT exist | `{ email: { exists: false } }` |
| `missing: true` | Field does NOT exist (alias for `exists: false`) | `{ email: { missing: true } }` |
| `missing: false` | Field exists (alias for `exists: true`) | `{ email: { missing: false } }` |
```typescript
// Find entities that have an email field
const withEmail = await brain.find({
where: { email: { exists: true } }
})
```
---
## Pattern (In-Memory Only)
These operators work via the in-memory filter path. They are applied **after** the indexed query, so use them with other indexed operators for best performance.
| Operator | Description | Example |
|----------|-------------|---------|
| `matches` | Regex or string pattern match | `{ name: { matches: /^Dr\./ } }` |
| `startsWith` | String prefix | `{ name: { startsWith: 'John' } }` |
| `endsWith` | String suffix | `{ email: { endsWith: '@gmail.com' } }` |
```typescript
const doctors = await brain.find({
where: {
type: NounType.Person, // Indexed — fast
name: { startsWith: 'Dr.' } // In-memory — applied after
}
})
```
---
## Logical
Combine multiple conditions:
| Operator | Description | Example |
|----------|-------------|---------|
| `allOf` | ALL sub-filters must match (AND) | `{ allOf: [{ status: 'active' }, { role: 'admin' }] }` |
| `anyOf` | ANY sub-filter must match (OR) | `{ anyOf: [{ role: 'admin' }, { role: 'owner' }] }` |
| `not` | Invert a filter | `{ not: { status: 'deleted' } }` |
```typescript
// Complex OR query
const adminsOrOwners = await brain.find({
where: {
anyOf: [
{ role: 'admin' },
{ role: 'owner' }
]
}
})
// NOT query
const notDeleted = await brain.find({
where: {
not: { status: 'deleted' }
}
})
// Combined AND + OR
const results = await brain.find({
where: {
allOf: [
{ department: 'engineering' },
{ anyOf: [
{ level: 'senior' },
{ yearsExperience: { greaterThan: 5 } }
]}
]
}
})
```
---
## Indexed vs In-Memory Operators
Brainy's MetadataIndex supports a subset of operators natively for O(1) field lookups. Other operators fall back to in-memory filtering.
| Operator | MetadataIndex (Indexed) | In-Memory Fallback |
|----------|:-----------------------:|:------------------:|
| `equals` / `eq` | Yes | Yes |
| `notEquals` / `ne` | — | Yes |
| `greaterThan` / `gt` | Yes | Yes |
| `greaterEqual` / `gte` | Yes | Yes |
| `lessThan` / `lt` | Yes | Yes |
| `lessEqual` / `lte` | Yes | Yes |
| `between` | Yes | Yes |
| `oneOf` / `in` | Yes | Yes |
| `noneOf` | — | Yes |
| `contains` | Yes | Yes |
| `exists` / `missing` | Yes | Yes |
| `matches` | — | Yes |
| `startsWith` | — | Yes |
| `endsWith` | — | Yes |
| `allOf` | Partial | Yes |
| `anyOf` | Partial | Yes |
| `not` | — | Yes |
**Performance tip:** Combine indexed operators (equals, greaterThan, oneOf, between, contains, exists) with pattern operators for optimal speed — the index narrows results first, then patterns filter in memory.
---
## Practical Examples
### Filter by entity type
```typescript
// Using the type shorthand (recommended)
brain.find({ type: NounType.Person })
// Using where.noun directly
brain.find({ where: { noun: NounType.Person } })
// Multiple types
brain.find({ type: [NounType.Person, NounType.Agent] })
```
### Combine semantic search with filters
```typescript
const results = await brain.find({
query: 'machine learning engineer', // Semantic search (on data)
type: NounType.Person, // Type filter (indexed)
where: {
department: 'engineering', // Exact match (indexed)
yearsExperience: { greaterThan: 3 } // Range filter (indexed)
},
limit: 10
})
```
### Temporal queries
```typescript
const lastWeek = Date.now() - 7 * 24 * 60 * 60 * 1000
const recentEntities = await brain.find({
where: {
createdAt: { greaterThan: lastWeek }
},
orderBy: 'createdAt',
order: 'desc',
limit: 50
})
```
### Graph + metadata combination
```typescript
const results = await brain.find({
connected: {
from: teamLeadId,
via: VerbType.WorksWith,
depth: 2
},
where: {
role: { oneOf: ['engineer', 'designer'] },
active: true
}
})
```

## What is Brainy?
Brainy is a next-generation AI database that combines:
- **Vector Search**: Semantic similarity using HNSW indexing
- **Graph Relationships**: Complex relationship mapping and traversal
- **Field Filtering**: Precise metadata filtering with O(1) lookups
- **Natural Language**: Query in plain English
## Key Features
### 🧠 Triple Intelligence Engine
All three intelligence types (vector, graph, field) work together in every query for optimal results.
### 📝 Noun-Verb Taxonomy
Model your data naturally as entities (nouns) and relationships (verbs) - no complex schemas needed.
### 🌍 Natural Language Queries
Ask questions in plain English and Brainy understands your intent:
```typescript
await brain.find("recent articles about AI with high ratings")
```
### ⚡ Production Ready
- Universal storage (FileSystem, S3, OPFS, Memory)
- Zero configuration with intelligent defaults
- Full TypeScript support
- Cross-platform compatibility
## Quick Example
```typescript ```typescript
import { Brainy, NounType, VerbType } from '@soulcraft/brainy' import { Brainy, NounType, VerbType } from '@soulcraft/brainy'
// Initialize
const brain = new Brainy() const brain = new Brainy()
await brain.init() await brain.init()
// Add entities (nouns) // Add entities — data is embedded for semantic search, metadata is indexed for filtering
const articleId = await brain.add({ const id = await brain.add({
data: "Revolutionary AI Breakthrough", data: 'Revolutionary AI Breakthrough',
type: NounType.Document, type: NounType.Document,
metadata: { category: "technology", rating: 4.8 } metadata: { category: 'technology', rating: 4.8 }
}) })
const authorId = await brain.add({ // Search with Triple Intelligence
data: "Dr. Sarah Chen", const results = await brain.find({
type: NounType.Person, query: 'artificial intelligence', // Semantic search (on data)
metadata: { role: "researcher" } where: { rating: { greaterThan: 4.0 } }, // Metadata filter
connected: { from: authorId, depth: 2 } // Graph traversal
}) })
// Create relationships (verbs)
await brain.relate({
from: authorId,
to: articleId,
type: VerbType.CreatedBy,
metadata: { date: "2024-01-15", contribution: "primary" }
})
// Query naturally
const results = await brain.find("highly rated technology articles by researchers")
``` ```

# Brainy Validation System
## Zero-Config Philosophy
Brainy's validation system automatically adapts to your system resources without any configuration. It enforces universal truths while dynamically adjusting limits based on available memory and observed performance.
## Core Principles
### 1. Universal Truths Only
We only validate things that are mathematically or logically impossible:
- Negative pagination values (there's no page -1)
- Probabilities outside 0-1 range
- Self-referential relationships
- Invalid enum values
### 2. Auto-Configuration
The system automatically configures based on:
- **Available Memory**: More RAM = higher limits
- **System Performance**: Adjusts based on query response times
- **Usage Patterns**: Learns from your actual workload
### 3. Performance Monitoring
Every query is monitored to tune future limits:
```typescript
// Automatic adjustment based on performance
if (avgQueryTime < 100ms && resultCount > 80% of limit) {
// Increase limits - system can handle more
maxLimit *= 1.5
} else if (avgQueryTime > 1000ms) {
// Reduce limits - system is struggling
maxLimit *= 0.8
}
```
## Validation Rules by Method
### `add(params: AddParams)`
**Required:**
- Either `data` or `vector` must be provided
- `type` must be a valid NounType enum
**Constraints:**
- `vector` must have exactly 384 dimensions (for all-MiniLM-L6-v2)
- Custom `id` must be unique
**Example:**
```typescript
// ✅ Valid
await brain.add({
data: "Hello world",
type: NounType.Document
})
// ✅ Valid - pre-computed vector
await brain.add({
vector: new Array(384).fill(0),
type: NounType.Document
})
// ❌ Invalid - missing both data and vector
await brain.add({
type: NounType.Document
})
// Error: "must provide either data or vector"
// ❌ Invalid - wrong vector dimensions
await brain.add({
vector: new Array(100).fill(0),
type: NounType.Document
})
// Error: "vector must have exactly 384 dimensions"
```
### `update(params: UpdateParams)`
**Required:**
- `id` must be provided
- At least one field must be updated
**Important Metadata Behavior:**
- `metadata: null` with `merge: false` → **Keeps existing metadata** (does nothing)
- `metadata: {}` with `merge: false` → **Clears metadata** ✅
- `metadata: undefined` → No change to metadata
**Example:**
```typescript
// ✅ Valid - update metadata
await brain.update({
id: "xyz",
metadata: { status: "published" }
})
// ✅ Valid - clear metadata properly
await brain.update({
id: "xyz",
metadata: {},
merge: false
})
// ❌ Invalid - null doesn't clear metadata
await brain.update({
id: "xyz",
metadata: null,
merge: false
})
// Error: "must specify at least one field to update"
// (because null metadata doesn't actually update anything)
// ❌ Invalid - no fields to update
await brain.update({
id: "xyz"
})
// Error: "must specify at least one field to update"
```
### `relate(params: RelateParams)`
**Required:**
- `from` entity ID
- `to` entity ID
- `type` must be valid VerbType enum
**Constraints:**
- `from` and `to` must be different (no self-loops)
- `weight` must be between 0 and 1
**Example:**
```typescript
// ✅ Valid
await brain.relate({
from: "entity1",
to: "entity2",
type: VerbType.RelatedTo
})
// ❌ Invalid - self-referential
await brain.relate({
from: "entity1",
to: "entity1",
type: VerbType.RelatedTo
})
// Error: "cannot create self-referential relationship"
// ❌ Invalid - weight out of range
await brain.relate({
from: "entity1",
to: "entity2",
type: VerbType.RelatedTo,
weight: 1.5
})
// Error: "weight must be between 0 and 1"
```
### `find(params: FindParams)`
**Constraints:**
- `limit` must be non-negative and below auto-configured maximum
- `offset` must be non-negative
- Cannot specify both `query` and `vector` (mutually exclusive)
- Cannot use both `cursor` and `offset` pagination
- `threshold` must be between 0 and 1
**Auto-Configured Limits:**
```typescript
// Based on available memory
// 1GB RAM → max limit: 10,000
// 8GB RAM → max limit: 80,000
// 16GB RAM → max limit: 100,000 (capped)
// Query length also scales with memory
// 1GB RAM → max query: 5,000 characters
// 8GB RAM → max query: 40,000 characters
```
**Example:**
```typescript
// ✅ Valid
await brain.find({
query: "machine learning",
limit: 50
})
// ❌ Invalid - negative limit
await brain.find({
query: "test",
limit: -1
})
// Error: "limit must be non-negative"
// ❌ Invalid - both query and vector
await brain.find({
query: "test",
vector: new Array(384).fill(0)
})
// Error: "cannot specify both query and vector - they are mutually exclusive"
// ❌ Invalid - exceeds auto-configured limit
await brain.find({
limit: 1000000
})
// Error: "limit exceeds auto-configured maximum of 80000 (based on available memory)"
```
## Auto-Configuration Details
### Memory-Based Scaling
The validation system checks available memory on initialization:
```typescript
const availableMemory = os.freemem()
// Scale limits based on available memory
maxLimit = Math.min(
100000, // Absolute maximum for safety
Math.floor(availableMemory / (1024 * 1024 * 100)) * 1000
)
// Scale query length similarly
maxQueryLength = Math.min(
50000,
Math.floor(availableMemory / (1024 * 1024 * 10)) * 1000
)
```
### Performance-Based Tuning
The system continuously monitors and adjusts:
1. **After each query**, performance is recorded
2. **Limits adjust** based on response times
3. **Gradual optimization** towards optimal throughput
### Checking Current Configuration
You can inspect the current validation configuration:
```typescript
import { getValidationConfig } from '@soulcraft/brainy/validation'
const config = getValidationConfig()
console.log(config)
// {
// maxLimit: 80000,
// maxQueryLength: 40000,
// maxVectorDimensions: 384,
// systemMemory: 17179869184,
// availableMemory: 8589934592
// }
```
## Best Practices
### 1. Clearing Metadata
```typescript
// ❌ Wrong - doesn't clear
await brain.update({ id, metadata: null, merge: false })
// ✅ Correct - actually clears
await brain.update({ id, metadata: {}, merge: false })
```
### 2. Type Safety
```typescript
// ❌ Wrong - string type
await brain.add({ data: "test", type: "document" })
// ✅ Correct - enum type
import { NounType } from '@soulcraft/brainy'
await brain.add({ data: "test", type: NounType.Document })
```
### 3. Pagination
```typescript
// ✅ Let the system auto-configure limits
const results = await brain.find({
query: "test",
limit: 100 // Will be capped at system maximum
})
// ✅ For large datasets, use pagination
let offset = 0
const pageSize = 1000
while (true) {
const results = await brain.find({
query: "test",
limit: pageSize,
offset
})
if (results.length === 0) break
offset += pageSize
}
```
## Error Messages
All validation errors are descriptive and actionable:
| Error | Cause | Solution |
|-------|-------|----------|
| `"must provide either data or vector"` | Missing content in add() | Provide either data to embed or pre-computed vector |
| `"limit must be non-negative"` | Negative pagination | Use positive limit value |
| `"invalid NounType: xyz"` | Invalid enum value | Use valid NounType enum |
| `"cannot create self-referential relationship"` | from === to | Use different entity IDs |
| `"must specify at least one field to update"` | Empty update | Provide at least one field to change |
| `"vector must have exactly 384 dimensions"` | Wrong vector size | Use 384-dimensional vectors |
## Performance Impact
The validation system adds minimal overhead:
- **Validation time**: <1ms per operation
- **Memory usage**: ~1KB for configuration tracking
- **Auto-tuning**: Happens asynchronously, no blocking
## FAQ
**Q: Why can't I set metadata to null?**
A: Setting metadata to `null` with `merge: false` doesn't actually clear it - it falls back to existing metadata. Use `{}` to clear.
**Q: Why are my limits being reduced?**
A: If queries are taking >1 second, the system automatically reduces limits to maintain performance.
**Q: Can I override the auto-configured limits?**
A: No, this is by design. The system knows better than static configuration what your hardware can handle.
**Q: Why exactly 384 dimensions for vectors?**
A: Brainy uses the all-MiniLM-L6-v2 model which produces 384-dimensional embeddings. This ensures consistency.
## Summary
Brainy's validation system:
- ✅ **Zero configuration** - adapts to your system
- ✅ **Universal truths** - only prevents impossible operations
- ✅ **Performance aware** - adjusts based on actual performance
- ✅ **Type safe** - enforces enum types
- ✅ **Minimal overhead** - <1ms validation time
- ✅ **Clear errors** - actionable error messages
The philosophy is simple: prevent impossible operations, adapt to reality, and get out of the way.

# 🚀 Brainy Zero-Configuration Guide
## Overview
Starting with v2.10, Brainy introduces a **Zero-Configuration System** that automatically configures everything based on your environment. No more environment variables, no more complex configuration objects - just create and use.
## Quick Start
### True Zero Config
```typescript
import { Brainy } from '@soulcraft/brainy'
// That's it! Everything auto-configures
const brain = new Brainy()
await brain.init()
```
### Using Strongly-Typed Presets
```typescript
import { Brainy, PresetName } from '@soulcraft/brainy'
// Type-safe preset selection
const brain = new Brainy(PresetName.PRODUCTION)
await brain.init()
```
### Common Scenarios
#### Development
```typescript
const brain = new Brainy(PresetName.DEVELOPMENT)
// ✅ Filesystem storage for persistence
// ✅ FP32 models for best quality
// ✅ Verbose logging
// ✅ All features enabled
```
#### Production
```typescript
const brain = new Brainy(PresetName.PRODUCTION)
// ✅ Disk storage for persistence
// ✅ Auto-selected model precision
// ✅ Silent logging
// ✅ Optimized features
```
#### Minimal
```typescript
const brain = new Brainy(PresetName.MINIMAL)
// ✅ Filesystem storage
// ✅ Q8 models for small size
// ✅ Core features only
// ✅ Minimal resource usage
```
## Distributed Architecture Presets
Brainy includes specialized presets for distributed and microservice architectures:
### Basic Distributed Roles
```typescript
import { Brainy, PresetName } from '@soulcraft/brainy'
// Write-only instance (data ingestion)
const writer = new Brainy(PresetName.WRITER)
// ✅ Optimized for writes
// ✅ No search index loading
// ✅ Minimal memory usage
// Read-only instance (search API)
const reader = new Brainy(PresetName.READER)
// ✅ Optimized for search
// ✅ Lazy index loading
// ✅ Large cache
```
### Service-Specific Presets
```typescript
// High-throughput data ingestion
const ingestion = new Brainy(PresetName.INGESTION_SERVICE)
// Low-latency search API
const searchApi = new Brainy(PresetName.SEARCH_API)
// Analytics processing
const analytics = new Brainy(PresetName.ANALYTICS_SERVICE)
// Edge location cache
const edge = new Brainy(PresetName.EDGE_CACHE)
// Batch processing
const batch = new Brainy(PresetName.BATCH_PROCESSOR)
// Real-time streaming
const streaming = new Brainy(PresetName.STREAMING_SERVICE)
// ML training
const training = new Brainy(PresetName.ML_TRAINING)
// Lightweight sidecar
const sidecar = new Brainy(PresetName.SIDECAR)
```
## Model Precision Control
You can **explicitly specify** model precision when needed:
```typescript
import { ModelPrecision } from '@soulcraft/brainy'
// Force FP32 (full precision)
const brain = new Brainy({ model: ModelPrecision.FP32 })
// Force Q8 (quantized, smaller)
const brain = new Brainy({ model: ModelPrecision.Q8 })
// Use presets
const brain = new Brainy({ model: ModelPrecision.FAST }) // Maps to fp32
const brain = new Brainy({ model: ModelPrecision.SMALL }) // Maps to q8
// Auto-detection (default)
const brain = new Brainy({ model: ModelPrecision.AUTO })
```
### Auto-Detection Logic
When not specified, Brainy automatically selects the best model:
- **Browser**: Q8 (smaller download)
- **Serverless**: Q8 (faster cold starts)
- **Low Memory (<512MB)**: Q8
- **Development**: FP32 (best quality)
- **Production (>2GB RAM)**: FP32
- **Default**: Q8 (balanced)
## Storage Configuration
### Automatic Storage Detection
Brainy automatically detects the best storage option:
1. **Cloud Storage** (if credentials found)
- AWS S3 (checks AWS_ACCESS_KEY_ID, AWS_PROFILE)
- Google Cloud Storage (checks GOOGLE_APPLICATION_CREDENTIALS)
- Cloudflare R2 (checks R2_ACCESS_KEY_ID)
2. **Browser Storage**
- OPFS (if supported)
- Filesystem fallback
3. **Node.js Storage**
- Filesystem (`./brainy-data` or `~/.brainy/data`)
### Manual Storage Control
```typescript
import { StorageOption } from '@soulcraft/brainy'
// Force specific storage with enum
const brain = new Brainy({ storage: StorageOption.DISK })
const brain = new Brainy({ storage: StorageOption.CLOUD })
const brain = new Brainy({ storage: StorageOption.AUTO })
// Custom storage configuration
const brain = new Brainy({
storage: {
s3Storage: {
bucket: 'my-bucket',
region: 'us-east-1'
}
}
})
```
## Feature Sets
Control which features are enabled:
```typescript
import { FeatureSet } from '@soulcraft/brainy'
// Preset feature sets with enum
const brain = new Brainy({ features: FeatureSet.MINIMAL }) // Core only
const brain = new Brainy({ features: FeatureSet.DEFAULT }) // Balanced
const brain = new Brainy({ features: FeatureSet.FULL }) // Everything
// Custom features
const brain = new Brainy({
features: ['core', 'search', 'cache', 'triple-intelligence']
})
```
## Simplified Configuration Interface
The new configuration is dramatically simpler:
```typescript
interface BrainyZeroConfig {
// Mode preset - now with distributed options
mode?: PresetName // All strongly typed presets
// Model configuration with enum
model?: ModelPrecision
// Storage configuration with enum
storage?: StorageOption | StorageConfig
// Feature set with enum
features?: FeatureSet | string[]
// Logging
verbose?: boolean
// Escape hatch for advanced users
advanced?: any
}
```
### Available Enums
```typescript
enum PresetName {
// Basic
PRODUCTION = 'production',
DEVELOPMENT = 'development',
MINIMAL = 'minimal',
ZERO = 'zero',
// Distributed
WRITER = 'writer',
READER = 'reader',
// Services
INGESTION_SERVICE = 'ingestion-service',
SEARCH_API = 'search-api',
ANALYTICS_SERVICE = 'analytics-service',
EDGE_CACHE = 'edge-cache',
BATCH_PROCESSOR = 'batch-processor',
STREAMING_SERVICE = 'streaming-service',
ML_TRAINING = 'ml-training',
SIDECAR = 'sidecar'
}
enum ModelPrecision {
FP32 = 'fp32',
Q8 = 'q8',
AUTO = 'auto',
FAST = 'fast', // Maps to fp32
SMALL = 'small' // Maps to q8
}
enum StorageOption {
AUTO = 'auto',
DISK = 'disk',
CLOUD = 'cloud'
}
enum FeatureSet {
MINIMAL = 'minimal',
DEFAULT = 'default',
FULL = 'full'
}
```
## Multi-Instance with Shared Storage
When multiple Brainy instances connect to the same storage (like S3), you **must ensure they use compatible configurations**:
```typescript
import { ModelPrecision } from '@soulcraft/brainy'
// Container A - Writer
const writer = new Brainy({
mode: PresetName.WRITER,
model: ModelPrecision.FP32, // ⚠️ MUST match across instances!
storage: { s3Storage: { bucket: 'shared-data' }}
})
// Container B - Reader
const reader = new Brainy({
mode: PresetName.READER,
model: ModelPrecision.FP32, // ✅ Matches Container A
storage: { s3Storage: { bucket: 'shared-data' }}
})
```
### Distributed Architecture Example
```typescript
// Ingestion Service (Writer)
const ingestion = new Brainy({
mode: PresetName.INGESTION_SERVICE,
model: ModelPrecision.Q8, // All instances must use Q8
storage: { s3Storage: { bucket: 'production-data' }}
})
// Search API (Reader)
const search = new Brainy({
mode: PresetName.SEARCH_API,
model: ModelPrecision.Q8, // Matches ingestion service
storage: { s3Storage: { bucket: 'production-data' }}
})
// Analytics (Hybrid)
const analytics = new Brainy({
mode: PresetName.ANALYTICS_SERVICE,
model: ModelPrecision.Q8, // Matches other services
storage: { s3Storage: { bucket: 'production-data' }}
})
```
## Migration from Old Configuration
### Before (Complex)
```typescript
const brain = new Brainy({
hnsw: {
M: 16,
efConstruction: 200,
seed: 42
},
storage: {
s3Storage: {
bucketName: 'my-bucket',
accessKeyId: process.env.AWS_ACCESS_KEY_ID,
secretAccessKey: process.env.AWS_SECRET_ACCESS_KEY,
region: 'us-east-1'
},
cacheConfig: {
hotCacheMaxSize: 5000,
hotCacheEvictionThreshold: 0.8,
warmCacheTTL: 3600000,
batchSize: 100
}
},
cache: {
autoTune: true,
autoTuneInterval: 60000,
hotCacheMaxSize: 10000
},
embeddingFunction: customFunction,
readOnly: false,
logging: { verbose: true }
})
```
### After (Simple)
```typescript
const brain = new Brainy('production')
// Everything above is auto-configured!
```
## Environment Variables (No Longer Needed!)
These environment variables are **no longer required**:
- ❌ `BRAINY_ALLOW_REMOTE_MODELS` - Models auto-download when needed
- ❌ `BRAINY_MODELS_PATH` - Path auto-selected based on environment
- ❌ `BRAINY_Q8_CONFIRMED` - Warnings auto-suppressed in production
- ❌ `BRAINY_LOG_LEVEL` - Auto-set based on NODE_ENV
- ❌ AWS credentials - Use AWS SDK credential chain
## Performance Impact
The zero-config system has **zero performance overhead**:
- Configuration happens once during initialization
- Auto-detected values are cached
- Same optimized code paths as manual configuration
- Actually **faster** startup due to reduced parsing
## Troubleshooting
### Models Not Downloading
- Check internet connection
- Ensure firewall allows HTTPS to Hugging Face / CDN
- Run `npm run download-models` to pre-download
### Wrong Model Precision
- Explicitly specify: `{ model: 'fp32' }` or `{ model: 'q8' }`
- Check shared storage compatibility
### Storage Detection Issues
- Check cloud credentials are properly configured
- Verify write permissions for filesystem paths
- Use explicit storage configuration if needed
## Best Practices
1. **Use zero-config for single instances** - Let Brainy handle everything
2. **Specify precision for shared storage** - Ensure compatibility
3. **Use presets for common scenarios** - 'development', 'production', 'minimal'
4. **Override only what you need** - Start simple, add complexity only if required
## Summary
The new zero-config system reduces configuration from **100+ parameters** to **0-3 decisions**:
| Scenario | Old Config Lines | New Config Lines |
|----------|-----------------|------------------|
| Development | 50+ | 1 |
| Production | 100+ | 1 |
| Custom | 200+ | 3-5 |
**Result**: 95% less configuration, 100% of the power! 🚀

# Brainy API Return Values
## Core Operations
### `brain.add()` - Adding Entities
**Returns:** `Promise<string>` - The ID of the created entity
```typescript
// ✅ Correct usage - add() returns the ID string directly
const id = await brain.add({
type: 'document',
data: 'My document content'
})
console.log('Created entity with ID:', id)
// Use the ID to create relationships
await brain.relate({
from: id,
to: anotherId,
type: 'references'
})
```
```typescript
// ❌ Incorrect - trying to access .id property
const result = await brain.add({
type: 'document',
data: 'My content'
})
console.log(result.id) // ❌ undefined - result IS the ID, not an object!
```
### Getting the Full Entity
If you need the full entity object after creation, use `brain.get()`:
```typescript
// Add entity and get its ID
const id = await brain.add({
type: 'document',
data: 'My content',
metadata: { label: 'Important Doc' }
})
// Get the full entity
const entity = await brain.get(id)
console.log(entity.id) // The ID
console.log(entity.type) // 'document'
console.log(entity.data) // 'My content'
console.log(entity.metadata) // { label: 'Important Doc', ... }
console.log(entity.vector) // The embedding vector
console.log(entity.createdAt) // Timestamp
```
### `brain.find()` - Finding Entities
**Returns:** `Promise<Entity[]>` - Array of full entity objects
```typescript
const entities = await brain.find({
query: 'machine learning',
limit: 10
})
// Each entity has full information
for (const entity of entities) {
console.log(entity.id)
console.log(entity.type)
console.log(entity.data)
console.log(entity.metadata)
}
```
### `brain.relate()` - Creating Relationships
**Returns:** `Promise<string>` - The ID of the created relationship
```typescript
const relationId = await brain.relate({
from: entityId1,
to: entityId2,
type: 'references'
})
console.log('Created relationship with ID:', relationId)
```
## Data Field Behavior
### String Data - Used for Embeddings
When `data` is a string, it's used to generate embeddings for semantic search:
```typescript
await brain.add({
type: 'document',
data: 'This text will be converted to an embedding vector',
metadata: {
title: 'My Document',
year: 2024
}
})
```
### Object Data - Structured Information
When `data` is an object, it's treated as structured data:
```typescript
await brain.add({
type: 'product',
data: {
name: 'Widget',
price: 29.99,
category: 'Tools'
},
vector: precomputedVector // Must provide vector when using object data
})
```
**Important:** If you provide object data without a `vector`, you must include a string somewhere for embedding generation, or the operation will fail.
### Metadata vs Data
- **`data`**: Primary content - used for embeddings (if string) or stored as structured data (if object)
- **`metadata`**: Auxiliary information - always stored as structured data, used for filtering
**Best practice for labels:**
```typescript
await brain.add({
type: 'document',
data: 'The full text content of the document...', // For semantic search
metadata: {
label: 'Quick Reference Label', // For display
author: 'John Doe',
category: 'Technical'
}
})
```
## Summary
| Method | Returns | Contains |
|--------|---------|----------|
| `brain.add()` | `string` | The ID of the created entity |
| `brain.get()` | `Entity \| null` | Full entity object with all fields |
| `brain.find()` | `Entity[]` | Array of full entity objects |
| `brain.relate()` | `string` | The ID of the created relationship |
| `brain.getRelations()` | `Relation[]` | Array of relationship objects |

# Brainy Complete Public API Reference
> **Accurate API documentation for Brainy**
## Initialization
```typescript
import { Brainy, NounType, VerbType } from '@soulcraft/brainy'
// Zero-config (just works)
const brain = new Brainy()
await brain.init()
// With configuration
const brain = new Brainy({
storage: { type: 'memory' }, // or { path: './my-data' } for filesystem
embeddingModel: 'Q8', // Q4, Q8, F16, F32
silent: true // Suppress logs
})
await brain.init()
```
## Readiness API
For reliable initialization detection, especially in cloud environments with progressive initialization:
### `brain.ready` - Await Initialization
```typescript
const brain = new Brainy()
brain.init() // Fire and forget
// Elsewhere (e.g., API handler)
await brain.ready // Wait until init() completes
const results = await brain.find({ query: 'test' })
```
### `brain.isInitialized` - Check Basic Readiness
```typescript
if (brain.isInitialized) {
// Safe to use brain methods
}
```
### `brain.isFullyInitialized()` - Check Background Tasks
```typescript
// Returns true when ALL initialization is complete, including background tasks
// Useful for cloud storage adapters with progressive initialization
if (brain.isFullyInitialized()) {
console.log('All background tasks complete')
}
```
### `brain.awaitBackgroundInit()` - Wait for Background Tasks
```typescript
const brain = new Brainy({ storage: { type: 'gcs', ... } })
await brain.init() // Fast return in cloud (<200ms)
// Optional: wait for all background tasks (bucket validation, count sync)
await brain.awaitBackgroundInit()
console.log('Fully initialized including background tasks')
```
### Health Check Pattern
```typescript
app.get('/health', async (req, res) => {
try {
await brain.ready
res.json({

{ start: new Date('2024-07-01'), end: new Date('2024-12-31'), label: 'H2' }
])
// Streaming clusters (for large datasets)
for await (const batch of neural.clusterStream({ batchSize: 100 })) {
console.log(`Progress: ${batch.progress.percentage}%`)
}
```
## Virtual File System (VFS)
Access via `brain.vfs`:
```typescript
const vfs = brain.vfs
await vfs.init()
// File operations
await vfs.writeFile('/docs/readme.md', '# Hello')
const content = await vfs.readFile('/docs/readme.md')
await vfs.unlink('/docs/readme.md')
// Directory operations
await vfs.mkdir('/project/src', { recursive: true })
const files = await vfs.readdir('/project')
await vfs.rmdir('/project', { recursive: true })
// Bulk operations
const result = await vfs.bulkWrite([
{ type: 'mkdir', path: '/data' },
{ type: 'write', path: '/data/config.json', data: '{}' },
{ type: 'write', path: '/data/users.json', data: '[]' }
])
// Note: mkdir operations run first (sequentially), then other ops in parallel
// Semantic search
const results = await vfs.search('authentication code', { path: '/src' })
// File metadata
const stats = await vfs.stat('/file.txt')
await vfs.setMetadata('/file.txt', { author: 'Alice' })
```
## Counts (O(1) Performance)
```typescript
// Entity counts
const total = brain.counts.entities()
const byType = await brain.counts.byType(NounType.Document)
const nonVFS = await brain.counts.byType({ excludeVFS: true })
// Relationship counts
const relations = brain.counts.relationships()
const byVerb = await brain.counts.byVerbType(VerbType.Contains)
```
## Versioning & Branching
```typescript
// Create branch
await brain.fork('feature-branch')
// List branches
const branches = await brain.listBranches()
// Switch branch
await brain.checkout('feature-branch')
// Get current branch
const current = await brain.getCurrentBranch()
// Commit changes
await brain.commit({ message: 'Added new features' })
// View history
const history = await brain.getHistory({ limit: 10 })
// Time travel (read-only snapshot)
const snapshot = await brain.asOf('commit-id')
```
## Streaming API
```typescript
// Stream all entities
for await (const entity of brain.streaming.entities()) {
console.log(entity.id)
}
// Stream with filters
for await (const entity of brain.streaming.entities({
type: NounType.Document,
where: { status: 'active' }
})) {
// Process each entity
}
// Stream relationships
for await (const relation of brain.streaming.relations({
from: 'entity-id'
})) {
console.log(relation)
}
```
## Pagination API
```typescript
// Paginated queries
const page1 = await brain.pagination.find({
query: 'machine learning',
page: 1,
pageSize: 20
})
console.log(`Page ${page1.page} of ${page1.totalPages}`)
console.log(`Total results: ${page1.total}`)
// Get next page
const page2 = await brain.pagination.find({
query: 'machine learning',
page: 2,
pageSize: 20
})
```
## Augmentations
```typescript
// List active augmentations
const augmentations = brain.augmentations.list()
// Get specific augmentation
const cache = brain.augmentations.get('cache')
// Augmentations are auto-loaded based on config
// Common augmentations: cache, display, metrics, intelligent-import
```
## Utilities
```typescript
// Manual embedding
const vector = await brain.embed('text to embed')
// Flush pending writes
await brain.flush()
// Get statistics
const stats = await brain.getStats()
const statsNoVFS = await brain.getStats({ excludeVFS: true })
// Close (cleanup)
await brain.close()
```
## Type Enums
```typescript
import { NounType, VerbType } from '@soulcraft/brainy'
// NounType - Entity types
NounType.Document
NounType.Person

```
## Error Handling
```typescript
try {
await brain.get('nonexistent-id')
} catch (error) {
if (error.message.includes('not found')) {
// Handle missing entity
}
}
// VFS errors use POSIX codes
try {
await vfs.readFile('/nonexistent')
} catch (error) {
if (error.code === 'ENOENT') {
// File not found
}
}
```
## Configuration Reference
```typescript
const brain = new Brainy({
// Storage
storage: {
type: 'memory' | 'filesystem',
path: './data', // For filesystem
forceMemoryStorage: false // Force memory even if path exists
},
// Embeddings

# Brainy Neural API Surface Design
## 🎯 **Clean API Hierarchy**
### **Main Class Shortcuts (Simple & Common)**
```typescript
// High-level shortcuts on Brainy - most common operations
brain.similar(a, b, options?) // ✅ Keep - very common
brain.clusters(items?, options?) // ✅ Keep - very common
brain.related(id, options?) // ✅ Keep - common (like neighbors but simpler name)
// Remove/deprecate confusing shortcuts
brain.visualize(options?) // ❌ Remove - too specialized for main class
```
### **Neural Namespace (Full Featured)**
```typescript
// Core semantic operations
brain.neural.similar(a, b, options?) // Comprehensive similarity
brain.neural.clusters(items?, options?) // Smart clustering with auto-routing
brain.neural.neighbors(id, options?) // K-nearest neighbors (full featured)
brain.neural.hierarchy(id, options?) // Semantic hierarchy building
brain.neural.outliers(options?) // Anomaly detection
brain.neural.visualize(options?) // Visualization data generation
// Advanced clustering methods
brain.neural.clusterByDomain(field, options?) // Domain-aware clustering
brain.neural.clusterByTime(field, windows, options?) // Temporal clustering
brain.neural.clusterStream(options?) // Streaming/real-time clustering
brain.neural.updateClusters(items, options?) // Incremental clustering
// Utility methods
brain.neural.getPerformanceMetrics(operation?) // Performance monitoring
brain.neural.clearCaches() // Cache management
brain.neural.getCacheStats() // Cache statistics
```
## 🔒 **Private Methods (Internal Implementation)**
### **Should NOT be exposed publicly:**
```typescript
// These are implementation details:
brain.neural._clusterFast() // ❌ Private - use clusters() with algorithm: 'hierarchical'
brain.neural._clusterLarge() // ❌ Private - use clusters() with algorithm: 'sample'
brain.neural._performHierarchicalClustering() // ❌ Private - internal routing
brain.neural._performKMeansClustering() // ❌ Private - internal routing
brain.neural._performDBSCANClustering() // ❌ Private - internal routing
brain.neural._performSampledClustering() // ❌ Private - internal routing
brain.neural._routeClusteringAlgorithm() // ❌ Private - internal routing
brain.neural._similarityById() // ❌ Private - internal routing
brain.neural._similarityByVector() // ❌ Private - internal routing
brain.neural._similarityByText() // ❌ Private - internal routing
brain.neural._isId() // ❌ Private - utility
brain.neural._isVector() // ❌ Private - utility
brain.neural._convertToVector() // ❌ Private - utility
brain.neural._cacheResult() // ❌ Private - caching
brain.neural._trackPerformance() // ❌ Private - monitoring
```
### **Current Issues in brain-cloud explorer:**
```typescript
// ❌ BAD: Accessing private implementation details
brain.neural.clusterFast({ maxClusters: count, level: 2 })
// ✅ GOOD: Use public API with proper options
brain.neural.clusters({ algorithm: 'hierarchical', maxClusters: count, level: 2 })
```
## 📊 **API Consistency Fixes**
### **Method Naming Standardization:**
```typescript
// ✅ CONSISTENT: Pick one naming pattern and stick to it
brain.neural.similar() // Main method name
brain.similar() // Shortcut matches
// ❌ INCONSISTENT: Don't mix these
brain.neural.similarity() // Different from shortcut
brain.similar()
```
### **Parameter Patterns:**
```typescript
// ✅ CONSISTENT: Always (data, options?) pattern
brain.neural.similar(a, b, options?)
brain.neural.clusters(items?, options?)
brain.neural.neighbors(id, options?)
brain.neural.hierarchy(id, options?)
// Options should be objects with clear properties
interface ClusteringOptions {
algorithm?: 'auto' | 'hierarchical' | 'kmeans' | 'dbscan'
maxClusters?: number
threshold?: number
// ...
}
```
### **Return Type Consistency:**
```typescript
// ✅ CONSISTENT: All clustering methods return SemanticCluster[]
brain.neural.clusters() → Promise<SemanticCluster[]>
brain.neural.clusterByDomain() → Promise<DomainCluster[]> // extends SemanticCluster
brain.neural.clusterByTime() → Promise<TemporalCluster[]> // extends SemanticCluster
// ✅ CONSISTENT: All similarity methods return number or SimilarityResult
brain.neural.similar() → Promise<number | SimilarityResult>
brain.similar() → Promise<number> // Shortcut always returns simple number
```
## 🚀 **Performance & Intelligence Routing**
### **Auto-Algorithm Selection:**
```typescript
// Smart routing based on data size and characteristics
brain.neural.clusters() // Auto-selects:
// < 100 items → hierarchical (fast, accurate)
// < 1000 items → k-means (balanced)
// > 1000 items → sampling (scalable)
// Manual override available
brain.neural.clusters({ algorithm: 'hierarchical' }) // Force specific algorithm
```
### **Caching Strategy:**
```typescript
// Intelligent caching with LRU eviction
brain.neural.similar('id1', 'id2') // First call: compute & cache
brain.neural.similar('id1', 'id2') // Second call: instant cache hit
// Cache management
brain.neural.clearCaches() // Manual cache clear
brain.neural.getCacheStats() // Monitor cache performance
```
## 📚 **Documentation Structure**
### **Main Documentation Sections:**
1. **Quick Start**: Simple examples using shortcuts (`brain.similar()`, `brain.clusters()`)
2. **Neural API Guide**: Comprehensive examples using `brain.neural.*`
3. **Advanced Clustering**: Domain, temporal, streaming clustering
4. **Performance**: Caching, algorithm selection, monitoring
5. **API Reference**: Complete method documentation
### **Example Progression:**
```typescript
// 1. BEGINNER: Simple shortcuts
const similarity = await brain.similar('text1', 'text2')
const clusters = await brain.clusters()
// 2. INTERMEDIATE: Neural API with options
const detailed = await brain.neural.similar('id1', 'id2', { detailed: true })
const customClusters = await brain.neural.clusters({ algorithm: 'hierarchical', maxClusters: 5 })
// 3. ADVANCED: Specialized clustering
const domainClusters = await brain.neural.clusterByDomain('category')
const streamingClusters = brain.neural.clusterStream({ batchSize: 50 })
```
## ✅ **Implementation Checklist**
### **High Priority:**
- [x] Create comprehensive type definitions
- [x] Implement improved NeuralAPI class with proper public/private separation
- [ ] Update Brainy integration to use improved API
- [ ] Fix brain-cloud explorer to use public APIs
- [ ] Update test files to use consistent method names
- [ ] Update documentation with new API structure
### **Medium Priority:**
- [ ] Implement placeholder algorithm implementations with real clustering logic
- [ ] Add comprehensive error handling and validation
- [ ] Add performance monitoring and metrics collection
- [ ] Create migration guide for users of deprecated methods
### **Nice to Have:**
- [ ] Add interactive clustering refinement based on user feedback
- [ ] Implement explainable clustering with reasoning
- [ ] Add multi-modal clustering (text + metadata + relationships)
- [ ] Create visualization examples for different graph libraries
## 🎯 **API Surface Summary**
### **✅ PUBLIC API** (What users should use):
- **Main shortcuts**: `brain.similar()`, `brain.clusters()`, `brain.related()`
- **Neural namespace**: `brain.neural.similar()`, `brain.neural.clusters()`, etc.
- **Advanced features**: Domain clustering, temporal clustering, streaming
- **Utilities**: Performance metrics, cache management
### **❌ PRIVATE IMPLEMENTATION** (Internal only):
- **Algorithm implementations**: `_performKMeansClustering()`, etc.
- **Routing logic**: `_routeClusteringAlgorithm()`, etc.
- **Utility methods**: `_isId()`, `_convertToVector()`, etc.
- **Caching internals**: `_cacheResult()`, `_trackPerformance()`, etc.
### **⚠️ DEPRECATED** (Should be removed/hidden):
- **brain.neural.clusterFast()** → Use `brain.neural.clusters({ algorithm: 'hierarchical' })`
- **brain.neural.clusterLarge()** → Use `brain.neural.clusters({ algorithm: 'sample' })`
- **brain.neural.similarity()** → Use `brain.neural.similar()` (pick one name)
- **brain.visualize()** → Too specialized for main class, use `brain.neural.visualize()`

# Brainy Metadata Architecture & Namespacing
## The Problem 🚨
We're mixing internal Brainy fields with user metadata, causing:
1. **Namespace collisions** - User's `deleted` field conflicts with our soft-delete
2. **API confusion** - Users see internal fields they shouldn't care about
3. **Security issues** - Users could manipulate internal fields
4. **Augmentation conflicts** - 3rd party augmentations might overwrite our fields
## Current Internal Fields Being Added
### Core System Fields
```javascript
metadata = {
// USER DATA
name: "Django",
type: "framework",
// OUR INTERNAL FIELDS - COLLISION RISK!
deleted: false, // Soft delete status
domain: "tech", // Distributed mode domain
domainMetadata: {}, // Domain-specific metadata
partition: 0, // Partition for sharding
createdAt: {...}, // GraphNoun timestamp
updatedAt: {...}, // GraphNoun timestamp
createdBy: {...}, // Who created this
noun: "Concept", // NounType
verb: "RELATES_TO", // VerbType (for relationships)
isPlaceholder: true, // Write-only mode marker
autoCreated: true, // Auto-created noun marker
writeOnlyMode: true // High-speed streaming marker
}
```
### Augmentation Fields
```javascript
// Good - neuralImport already uses underscore prefix!
metadata._neuralProcessed = true
metadata._neuralConfidence = 0.95
metadata._detectedEntities = 5
metadata._detectedRelationships = 3
metadata._neuralInsights = [...]
// Bad - direct modification
metadata.importance = 0.8 // IntelligentVerbScoring
```
## Proposed Solution: Three-Tier Metadata
### 1. User Metadata (Public)
```javascript
metadata = {
// User's fields - completely untouched
name: "Django",
type: "framework",
deleted: "2024-01-01", // User's own deleted field - no conflict!
domain: "web", // User's domain field - no conflict!
}
```
### 2. Internal Metadata (Protected)
```javascript
metadata._brainy = {
// Core system fields - O(1) indexed
deleted: false, // Our soft delete flag
version: 2, // Metadata schema version
// Distributed mode
partition: 0,
distributedDomain: "tech",
// GraphNoun compliance
nounType: "Concept",
verbType: "RELATES_TO",
createdAt: 1704067200000,
updatedAt: 1704067200000,
createdBy: "user:123",
// Performance flags
indexed: true,
searchable: true,
placeholder: false,
// Storage optimization
compressed: false,
encrypted: false
}
```
### 3. Augmentation Metadata (Semi-Protected)
```javascript
metadata._augmentations = {
// Each augmentation gets its own namespace
neuralImport: {
processed: true,
confidence: 0.95,
entities: 5,
relationships: 3
},
verbScoring: {
contextScore: 0.7,
importance: 0.8
},
// 3rd party augmentations
customAug: {
// Their fields isolated here
}
}
```
## Implementation Strategy
### Phase 1: Core Fields ✅
```javascript
// Already done with _brainy.deleted
const BRAINY_NAMESPACE = '_brainy'
const AUGMENTATION_NAMESPACE = '_augmentations'
```
### Phase 2: Migrate All Internal Fields
```javascript
// Before
metadata.domain = "tech"
metadata.partition = 0
// After
metadata._brainy.distributedDomain = "tech"
metadata._brainy.partition = 0
```
### Phase 3: Augmentation API
```javascript
class Augmentation {
// Read user metadata (read-only)
getUserMetadata(metadata) {
const { _brainy, _augmentations, ...userMeta } = metadata
return userMeta // Clean user data only
}
// Write augmentation data (isolated)
setAugmentationData(metadata, augName, data) {
if (!metadata._augmentations) metadata._augmentations = {}
metadata._augmentations[augName] = data
}
// Read internal fields (for special augmentations only)
getInternalField(metadata, field) {
return metadata._brainy?.[field]
}
}
```
## Benefits
1. **No Collisions** - User can have any field names
2. **O(1) Performance** - Internal fields still indexed
3. **Clean API** - Users only see their data
4. **Secure** - Internal fields protected
5. **Extensible** - Augmentations isolated
6. **Backward Compatible** - Migration path available
## Query Impact
### Before (Collision Risk)
```javascript
where: {
deleted: false, // Ambiguous - ours or user's?
type: "framework"
}
```
### After (Clear Separation)
```javascript
where: {
'_brainy.deleted': false, // Our soft delete
type: "framework" // User's field
}
```
## Performance Considerations
- **Index on `_brainy.deleted`**: O(1) hash lookup ✅
- **Index on `_brainy.partition`**: O(1) for sharding ✅
- **Nested field access**: Modern DBs handle this efficiently ✅
- **Storage overhead**: ~100 bytes per item (acceptable) ✅
## Migration Path
1. **New items**: Automatically use namespaced fields
2. **Existing items**: Lazy migration on update
3. **Queries**: Support both formats temporarily
4. **Deprecation**: Remove old format in v3.0
## Augmentation Guidelines
### For Core Augmentations
- Use `_brainy.*` for system fields
- Use `_augmentations.{name}.*` for augmentation data
- Never modify user fields directly
### For 3rd Party Augmentations
- Read user metadata via `getUserMetadata()`
- Write only to `_augmentations.{yourName}.*`
- Request permission for internal field access
## Critical Fields to Namespace
| Field | Current Location | New Location | Priority |
|-------|-----------------|--------------|----------|
| deleted | metadata.deleted | metadata._brainy.deleted | HIGH ✅ |
| partition | metadata.partition | metadata._brainy.partition | HIGH |
| domain | metadata.domain | metadata._brainy.distributedDomain | HIGH |
| createdAt | metadata.createdAt | metadata._brainy.createdAt | MEDIUM |
| updatedAt | metadata.updatedAt | metadata._brainy.updatedAt | MEDIUM |
| noun | metadata.noun | metadata._brainy.nounType | MEDIUM |
| verb | metadata.verb | metadata._brainy.verbType | MEDIUM |
| isPlaceholder | metadata.isPlaceholder | metadata._brainy.placeholder | LOW |
| autoCreated | metadata.autoCreated | metadata._brainy.autoCreated | LOW |
