+## 🎯 Use Cases
+
+### Building a Nostr Client
+```typescript
+// Initialize
+const { ndk, isConnected } = await initializeNDK({
+  relays: ['wss://relay.damus.io', 'wss://nos.lol'],
+  timeoutMs: 10000
+})
+
+// Authenticate
+const { user } = await loginWithExtension(ndk)
+
+// Publish
+await publishBasicNote(ndk, 'Hello Nostr!')
+
+// Subscribe
+const sub = subscribeToNotes(ndk, user.pubkey, (event) => {
+  console.log('New note:', event.content)
+})
+```
+
+### Building a Marketplace
+```typescript
+// Publish product
+await publishProduct(ndk, {
+  slug: 'bitcoin-shirt',
+  title: 'Bitcoin T-Shirt',
+  price: 25,
+  currency: 'USD',
+  images: ['https://...']
+})
+
+// Create order
+await createOrder(ndk, {
+  orderId: uuidv4(),
+  sellerPubkey: merchant.pubkey,
+  productRef: '30402:pubkey:bitcoin-shirt',
+  quantity: 1,
+  totalAmount: '25.00'
+})
+
+// Monitor payment
+monitorPaymentReceipt(ndk, orderId, invoiceId, (preimage) => {
+  console.log('Payment confirmed!')
+})
+```
+
+### React Integration
+```typescript
+function Feed() {
+  const ndk = useNDK()
+  const { user } = useAuth()
+  
+  // Query with real-time updates
+  const { data: notes } = useNotesWithSubscription(
+    ndk,
+    user.pubkey
+  )
+  
+  return (
+    <div>
+      {notes?.map(note => (
+        <NoteCard key={note.id} note={note} />
+      ))}
+    </div>
+  )
+}
+```
+
+## 🔍 Common Patterns Quick Reference
+
+### Safe NDK Access
+```typescript
+const ndk = ndkActions.getNDK()
+if (!ndk) throw new Error('NDK not initialized')
+```
+
+### Subscription Cleanup
+```typescript
+useEffect(() => {
+  const sub = ndk.subscribe(filter, { closeOnEose: false })
+  sub.on('event', handleEvent)
+  return () => sub.stop()  // Critical!
+}, [ndk])
+```
+
+### Error Handling
+```typescript
+try {
+  await event.sign()
+  await event.publish()
+} catch (error) {
+  console.error('Publishing failed:', error)
+  throw new Error('Failed to publish. Check connection.')
+}
+```
+
+### Tag Filtering
+```typescript
+// ✅ Correct (note the # prefix for tag filters)
+{ kinds: [16], '#order': [orderId] }
+
+// ❌ Wrong
+{ kinds: [16], 'order': [orderId] }
+```
+
+## 🛠 Development Tools
+
+### VS Code Integration
+These skill files work with:
+- Cursor AI for code completion
+- Claude for code assistance
+- GitHub Copilot with context
+
+### Debugging Tips
+```typescript
+// Check connection
+console.log('Connected relays:', 
+  Array.from(ndk.pool?.relays.values() || [])
+    .filter(r => r.status === 1)
+    .map(r => r.url)
+)
+
+// Verify signer
+console.log('Signer:', ndk.signer)
+console.log('Active user:', ndk.activeUser)
+
+// Event inspection
+console.log('Event:', {
+  id: event.id,
+  kind: event.kind,
+  tags: event.tags,
+  sig: event.sig
+})
+```

+# NDK (Nostr Development Kit) - Claude Skill Reference
+
+## Overview
+
+NDK is the primary Nostr development kit with outbox-model support, designed for building Nostr applications with TypeScript/JavaScript. This reference is based on analyzing production usage in the Plebeian Market codebase.
+
+## Core Concepts
+
+### 1. NDK Initialization
+
+**Basic Pattern:**
+```typescript
+import NDK from '@nostr-dev-kit/ndk'
+
+// Simple initialization
+const ndk = new NDK({
+  explicitRelayUrls: ['wss://relay.damus.io', 'wss://relay.nostr.band']
+})
+
+await ndk.connect()
+```
+
+**Store-based Pattern (Production):**
+```typescript
+// From src/lib/stores/ndk.ts
+const ndk = new NDK({
+  explicitRelayUrls: relays || defaultRelaysUrls,
+})
+
+// Separate NDK for zaps on specialized relays
+const zapNdk = new NDK({
+  explicitRelayUrls: ZAP_RELAYS,
+})
+
+// Connect with timeout protection
+const connectPromise = ndk.connect()
+const timeoutPromise = new Promise((_, reject) => 
+  setTimeout(() => reject(new Error('Connection timeout')), timeoutMs)
+)
+await Promise.race([connectPromise, timeoutPromise])
+```
+
+### 2. Authentication & Signers
+
+NDK supports multiple signer types for different authentication methods:
+
+#### NIP-07 (Browser Extension)
+```typescript
+import { NDKNip07Signer } from '@nostr-dev-kit/ndk'
+
+const signer = new NDKNip07Signer()
+await signer.blockUntilReady()
+ndk.signer = signer
+
+const user = await signer.user()
+```
+
+#### Private Key Signer
+```typescript
+import { NDKPrivateKeySigner } from '@nostr-dev-kit/ndk'
+
+const signer = new NDKPrivateKeySigner(privateKeyHex)
+await signer.blockUntilReady()
+ndk.signer = signer
+
+const user = await signer.user()
+```
+
+#### NIP-46 (Remote Signer / Bunker)
+```typescript
+import { NDKNip46Signer } from '@nostr-dev-kit/ndk'
+
+const localSigner = new NDKPrivateKeySigner(localPrivateKey)
+const remoteSigner = new NDKNip46Signer(ndk, bunkerUrl, localSigner)
+await remoteSigner.blockUntilReady()
+ndk.signer = remoteSigner
+
+const user = await remoteSigner.user()
+```
+
+**Key Points:**
+- Always call `blockUntilReady()` before using a signer
+- Store signer reference in your state management
+- Set `ndk.signer` to enable signing operations
+- Use `await signer.user()` to get the authenticated user
+
+### 3. Event Creation & Publishing
+
+#### Basic Event Pattern
+```typescript
+import { NDKEvent } from '@nostr-dev-kit/ndk'
+
+// Create event
+const event = new NDKEvent(ndk)
+event.kind = 1  // Kind 1 = text note
+event.content = "Hello Nostr!"
+event.tags = [
+  ['t', 'nostr'],
+  ['p', recipientPubkey]
+]
+
+// Sign and publish
+await event.sign()  // Uses ndk.signer automatically
+await event.publish()
+
+// Get event ID after signing
+console.log(event.id)
+```
+
+#### Production Pattern with Error Handling
+```typescript
+// From src/publish/orders.tsx
+const event = new NDKEvent(ndk)
+event.kind = ORDER_PROCESS_KIND
+event.content = orderNotes || ''
+event.tags = [
+  ['p', sellerPubkey],
+  ['subject', `Order for ${productName}`],
+  ['type', 'order-creation'],
+  ['order', orderId],
+  ['amount', totalAmount],
+  ['item', productRef, quantity.toString()],
+]
+
+// Optional tags
+if (shippingRef) {
+  event.tags.push(['shipping', shippingRef])
+}
+
+try {
+  await event.sign(signer)  // Can pass explicit signer
+  await event.publish()
+  return event.id
+} catch (error) {
+  console.error('Failed to publish event:', error)
+  throw error
+}
+```
+
+**Key Points:**
+- Create event with `new NDKEvent(ndk)`
+- Set `kind`, `content`, and `tags` properties
+- Optional: Set `created_at` timestamp (defaults to now)
+- Call `await event.sign()` before publishing
+- Call `await event.publish()` to broadcast to relays
+- Access `event.id` after signing for the event hash
+
+### 4. Querying Events with Filters
+
+#### fetchEvents() - One-time Fetch
+```typescript
+import { NDKFilter } from '@nostr-dev-kit/ndk'
+
+// Simple filter
+const filter: NDKFilter = {
+  kinds: [30402],  // Product listings
+  authors: [merchantPubkey],
+  limit: 50
+}
+
+const events = await ndk.fetchEvents(filter)
+// Returns Set<NDKEvent>
+
+// Convert to array and process
+const eventArray = Array.from(events)
+const sortedEvents = eventArray.sort((a, b) => 
+  (b.created_at || 0) - (a.created_at || 0)
+)
+```
+
+#### Advanced Filters
+```typescript
+// Multiple kinds
+const filter: NDKFilter = {
+  kinds: [16, 17],  // Orders and payment receipts
+  '#order': [orderId],  // Tag filter (# prefix)
+  since: Math.floor(Date.now() / 1000) - 86400,  // Last 24 hours
+  limit: 100
+}
+
+// Event ID lookup
+const filter: NDKFilter = {
+  ids: [eventIdHex],
+}
+
+// Tag filtering
+const filter: NDKFilter = {
+  kinds: [1],
+  '#p': [pubkey],  // Events mentioning pubkey
+  '#t': ['nostr'],  // Events with hashtag 'nostr'
+}
+```
+
+### 5. Subscriptions (Real-time)
+
+#### Basic Subscription
+```typescript
+// From src/queries/blacklist.tsx
+const filter = {
+  kinds: [10000],
+  authors: [appPubkey],
+}
+
+const subscription = ndk.subscribe(filter, {
+  closeOnEose: false,  // Keep open for real-time updates
+})
+
+subscription.on('event', (event: NDKEvent) => {
+  console.log('New event received:', event)
+  // Process event
+})
+
+subscription.on('eose', () => {
+  console.log('End of stored events')
+})
+
+// Cleanup
+subscription.stop()
+```
+
+#### Production Pattern with React Query
+```typescript
+// From src/queries/orders.tsx
+useEffect(() => {
+  if (!orderId || !ndk) return
+
+  const filter = {
+    kinds: [ORDER_PROCESS_KIND, PAYMENT_RECEIPT_KIND],
+    '#order': [orderId],
+  }
+
+  const subscription = ndk.subscribe(filter, {
+    closeOnEose: false,
+  })
+
+  subscription.on('event', (newEvent) => {
+    // Invalidate React Query cache to trigger refetch
+    queryClient.invalidateQueries({ 
+      queryKey: orderKeys.details(orderId) 
+    })
+  })
+
+  // Cleanup on unmount
+  return () => {
+    subscription.stop()
+  }
+}, [orderId, ndk, queryClient])
+```
+
+#### Monitoring Specific Events
+```typescript
+// From src/queries/payment.tsx - Payment receipt monitoring
+const receiptFilter = {
+  kinds: [17],  // Payment receipts
+  '#order': [orderId],
+  '#payment-request': [invoiceId],
+  since: sessionStartTime - 30,  // Clock skew buffer
+}
+
+const subscription = ndk.subscribe(receiptFilter, {
+  closeOnEose: false,
+})
+
+subscription.on('event', (receiptEvent: NDKEvent) => {
+  // Verify this is the correct invoice
+  const paymentRequestTag = receiptEvent.tags.find(
+    tag => tag[0] === 'payment-request'
+  )
+  
+  if (paymentRequestTag?.[1] === invoiceId) {
+    const paymentTag = receiptEvent.tags.find(tag => tag[0] === 'payment')
+    const preimage = paymentTag?.[3] || 'external-payment'
+    
+    // Stop subscription after finding payment
+    subscription.stop()
+    handlePaymentReceived(preimage)
+  }
+})
+```
+
+**Key Subscription Patterns:**
+- Use `closeOnEose: false` for real-time monitoring
+- Use `closeOnEose: true` for one-time historical fetch
+- Always call `subscription.stop()` in cleanup
+- Listen to both `'event'` and `'eose'` events
+- Filter events in the handler for specific conditions
+- Integrate with React Query for reactive UI updates
+
+### 6. User & Profile Handling
+
+#### Fetching User Profiles
+```typescript
+// From src/queries/profiles.tsx
+
+// By npub
+const user = ndk.getUser({ npub })
+const profile = await user.fetchProfile()
+// Returns NDKUserProfile with name, picture, about, etc.
+
+// By hex pubkey
+const user = ndk.getUser({ hexpubkey: pubkey })
+const profile = await user.fetchProfile()
+
+// By NIP-05 identifier
+const user = await ndk.getUserFromNip05('user@domain.com')
+if (user) {
+  const profile = await user.fetchProfile()
+}
+
+// Profile fields
+const name = profile?.name || profile?.displayName
+const avatar = profile?.picture || profile?.image
+const bio = profile?.about
+const nip05 = profile?.nip05
+const lud16 = profile?.lud16  // Lightning address
+```
+
+#### Getting Current User
+```typescript
+// Active user (authenticated)
+const user = ndk.activeUser
+
+// From signer
+const user = await ndk.signer?.user()
+
+// User properties
+const pubkey = user.pubkey  // Hex format
+const npub = user.npub      // NIP-19 encoded
+```
+
+### 7. NDK Event Object
+
+#### Essential Properties
+```typescript
+interface NDKEvent {
+  id: string                 // Event hash (after signing)
+  kind: number              // Event kind
+  content: string           // Event content
+  tags: NDKTag[]           // Array of tag arrays
+  created_at?: number      // Unix timestamp
+  pubkey?: string          // Author pubkey (after signing)
+  sig?: string             // Signature (after signing)
+  
+  // Methods
+  sign(signer?: NDKSigner): Promise<void>
+  publish(): Promise<void>
+  tagValue(tagName: string): string | undefined
+}
+
+type NDKTag = string[]  // e.g., ['p', pubkey, relay, petname]
+```
+
+#### Tag Helpers
+```typescript
+// Get first value of a tag
+const orderId = event.tagValue('order')
+const recipientPubkey = event.tagValue('p')
+
+// Find specific tag
+const paymentTag = event.tags.find(tag => tag[0] === 'payment')
+const preimage = paymentTag?.[3]
+
+// Get all tags of a type
+const pTags = event.tags.filter(tag => tag[0] === 'p')
+const allPubkeys = pTags.map(tag => tag[1])
+
+// Common tag patterns
+event.tags.push(['p', pubkey])                    // Mention
+event.tags.push(['e', eventId])                   // Reference event
+event.tags.push(['t', 'nostr'])                   // Hashtag
+event.tags.push(['d', identifier])                // Replaceable event ID
+event.tags.push(['a', '30402:pubkey:d-tag'])     // Addressable event reference
+```
+
+### 8. Parameterized Replaceable Events (NIP-33)
+
+Used for products, collections, profiles that need updates:
+
+```typescript
+// Product listing (kind 30402)
+const event = new NDKEvent(ndk)
+event.kind = 30402
+event.content = JSON.stringify(productDetails)
+event.tags = [
+  ['d', productSlug],          // Unique identifier
+  ['title', productName],
+  ['price', price, currency],
+  ['image', imageUrl],
+  ['shipping', shippingRef],
+]
+
+await event.sign()
+await event.publish()
+
+// Querying replaceable events
+const filter = {
+  kinds: [30402],
+  authors: [merchantPubkey],
+  '#d': [productSlug],  // Specific product
+}
+
+const events = await ndk.fetchEvents(filter)
+// Returns only the latest version due to replaceable nature
+```
+
+### 9. Relay Management
+
+#### Getting Relay Status
+```typescript
+// From src/lib/stores/ndk.ts
+const connectedRelays = Array.from(ndk.pool?.relays.values() || [])
+  .filter(relay => relay.status === 1)  // 1 = connected
+  .map(relay => relay.url)
+
+const outboxRelays = Array.from(ndk.outboxPool?.relays.values() || [])
+```
+
+#### Adding Relays
+```typescript
+// Add explicit relays
+ndk.addExplicitRelay('wss://relay.example.com')
+
+// Multiple relays
+const relays = ['wss://relay1.com', 'wss://relay2.com']
+relays.forEach(url => ndk.addExplicitRelay(url))
+```
+
+### 10. Common Patterns & Best Practices
+
+#### Null Safety
+```typescript
+// Always check NDK initialization
+const ndk = ndkActions.getNDK()
+if (!ndk) throw new Error('NDK not initialized')
+
+// Check signer before operations requiring auth
+const signer = ndk.signer
+if (!signer) throw new Error('No active signer')
+
+// Check user authentication
+const user = ndk.activeUser
+if (!user) throw new Error('Not authenticated')
+```
+
+#### Error Handling
+```typescript
+try {
+  const events = await ndk.fetchEvents(filter)
+  if (events.size === 0) {
+    return null  // No results found
+  }
+  return Array.from(events)
+} catch (error) {
+  console.error('Failed to fetch events:', error)
+  throw new Error('Could not fetch data from relays')
+}
+```
+
+#### Connection Lifecycle
+```typescript
+// Initialize once at app startup
+const ndk = new NDK({ explicitRelayUrls: relays })
+
+// Connect with timeout
+await Promise.race([
+  ndk.connect(),
+  new Promise((_, reject) => 
+    setTimeout(() => reject(new Error('Timeout')), 10000)
+  )
+])
+
+// Check connection status
+const isConnected = ndk.pool?.connectedRelays().length > 0
+
+// Reconnect if needed
+if (!isConnected) {
+  await ndk.connect()
+}
+```
+
+#### Subscription Cleanup
+```typescript
+// In React components
+useEffect(() => {
+  if (!ndk) return
+  
+  const sub = ndk.subscribe(filter, { closeOnEose: false })
+  
+  sub.on('event', handleEvent)
+  sub.on('eose', handleEose)
+  
+  // Critical: cleanup on unmount
+  return () => {
+    sub.stop()
+  }
+}, [dependencies])
+```
+
+#### Event Validation
+```typescript
+// Check required fields before processing
+if (!event.pubkey) {
+  console.error('Event missing pubkey')
+  return
+}
+
+if (!event.created_at) {
+  console.error('Event missing timestamp')
+  return
+}
+
+// Verify event age
+const now = Math.floor(Date.now() / 1000)
+const eventAge = now - (event.created_at || 0)
+if (eventAge > 86400) {  // Older than 24 hours
+  console.log('Event is old, skipping')
+  return
+}
+
+// Validate specific tags exist
+const orderId = event.tagValue('order')
+if (!orderId) {
+  console.error('Order event missing order ID')
+  return
+}
+```
+
+### 11. Common Event Kinds
+
+```typescript
+// NIP-01: Basic Events
+const KIND_METADATA = 0         // User profile
+const KIND_TEXT_NOTE = 1        // Short text note
+const KIND_RECOMMEND_RELAY = 2  // Relay recommendation
+
+// NIP-04: Encrypted Direct Messages
+const KIND_ENCRYPTED_DM = 4
+
+// NIP-25: Reactions
+const KIND_REACTION = 7
+
+// NIP-51: Lists
+const KIND_MUTE_LIST = 10000
+const KIND_PIN_LIST = 10001
+const KIND_RELAY_LIST = 10002
+
+// NIP-57: Lightning Zaps
+const KIND_ZAP_REQUEST = 9734
+const KIND_ZAP_RECEIPT = 9735
+
+// Marketplace (Plebeian/Gamma spec)
+const ORDER_PROCESS_KIND = 16      // Order processing
+const PAYMENT_RECEIPT_KIND = 17    // Payment receipts
+const DIRECT_MESSAGE_KIND = 14     // Direct messages
+const ORDER_GENERAL_KIND = 27      // General order events
+const SHIPPING_KIND = 30405        // Shipping options
+const PRODUCT_KIND = 30402         // Product listings
+const COLLECTION_KIND = 30401      // Product collections
+const REVIEW_KIND = 30407          // Product reviews
+
+// Application Handlers
+const APP_HANDLER_KIND = 31990     // NIP-89 app handlers
+```
+
+## Integration with TanStack Query
+
+NDK works excellently with TanStack Query for reactive data fetching:
+
+### Query Functions
+```typescript
+// From src/queries/products.tsx
+export const fetchProductsByPubkey = async (pubkey: string) => {
+  const ndk = ndkActions.getNDK()
+  if (!ndk) throw new Error('NDK not initialized')
+
+  const filter: NDKFilter = {
+    kinds: [30402],
+    authors: [pubkey],
+  }
+
+  const events = await ndk.fetchEvents(filter)
+  return Array.from(events).map(parseProductEvent)
+}
+
+export const useProductsByPubkey = (pubkey: string) => {
+  return useQuery({
+    queryKey: productKeys.byAuthor(pubkey),
+    queryFn: () => fetchProductsByPubkey(pubkey),
+    enabled: !!pubkey,
+    staleTime: 30000,
+  })
+}
+```
+
+### Combining Queries with Subscriptions
+```typescript
+// Query for initial data
+const { data: order, refetch } = useQuery({
+  queryKey: orderKeys.details(orderId),
+  queryFn: () => fetchOrderById(orderId),
+  enabled: !!orderId,
+})
+
+// Subscription for real-time updates
+useEffect(() => {
+  if (!orderId || !ndk) return
+
+  const sub = ndk.subscribe(
+    { kinds: [16, 17], '#order': [orderId] },
+    { closeOnEose: false }
+  )
+
+  sub.on('event', () => {
+    // Invalidate query to trigger refetch
+    queryClient.invalidateQueries({ 
+      queryKey: orderKeys.details(orderId) 
+    })
+  })
+
+  return () => sub.stop()
+}, [orderId, ndk, queryClient])
+```
+
+## Troubleshooting
+
+### Events Not Received
+- Check relay connections: `ndk.pool?.connectedRelays()`
+- Verify filter syntax (especially tag filters with `#` prefix)
+- Check event timestamps match filter's `since`/`until`
+- Ensure `closeOnEose: false` for real-time subscriptions
+
+### Signing Errors
+- Verify signer is initialized: `await signer.blockUntilReady()`
+- Check signer is set: `ndk.signer !== undefined`
+- For NIP-07, ensure browser extension is installed and enabled
+- For NIP-46, verify bunker URL and local signer are correct
+
+### Connection Timeouts
+- Implement connection timeout pattern shown above
+- Try connecting to fewer, more reliable relays initially
+- Use fallback relays in production
+
+### Duplicate Events
+- NDK deduplicates by event ID automatically
+- For subscriptions, track processed event IDs if needed
+- Use replaceable events (kinds 10000-19999, 30000-39999) when appropriate
+
+## Performance Optimization
+
+### Batching Queries
+```typescript
+// Instead of multiple fetchEvents calls
+const [products, orders, profiles] = await Promise.all([
+  ndk.fetchEvents(productFilter),
+  ndk.fetchEvents(orderFilter),
+  ndk.fetchEvents(profileFilter),
+])
+```
+
+### Limiting Results
+```typescript
+const filter = {
+  kinds: [1],
+  authors: [pubkey],
+  limit: 50,  // Limit results
+  since: recentTimestamp,  // Only recent events
+}
+```
+
+### Caching with React Query
+```typescript
+export const useProfile = (npub: string) => {
+  return useQuery({
+    queryKey: profileKeys.byNpub(npub),
+    queryFn: () => fetchProfileByNpub(npub),
+    staleTime: 5 * 60 * 1000,  // 5 minutes
+    cacheTime: 30 * 60 * 1000,  // 30 minutes
+    enabled: !!npub,
+  })
+}
+```

+# NDK Quick Reference
+
+Fast lookup guide for common NDK tasks.
+
+## Quick Start
+
+```typescript
+import NDK from '@nostr-dev-kit/ndk'
+
+const ndk = new NDK({ explicitRelayUrls: ['wss://relay.damus.io'] })
+await ndk.connect()
+```
+
+## Authentication
+
+### Browser Extension (NIP-07)
+```typescript
+import { NDKNip07Signer } from '@nostr-dev-kit/ndk'
+const signer = new NDKNip07Signer()
+await signer.blockUntilReady()
+ndk.signer = signer
+```
+
+### Private Key
+```typescript
+import { NDKPrivateKeySigner } from '@nostr-dev-kit/ndk'
+const signer = new NDKPrivateKeySigner(privateKeyHex)
+await signer.blockUntilReady()
+ndk.signer = signer
+```
+
+### Remote Signer (NIP-46)
+```typescript
+import { NDKNip46Signer, NDKPrivateKeySigner } from '@nostr-dev-kit/ndk'
+const localSigner = new NDKPrivateKeySigner()
+const remoteSigner = new NDKNip46Signer(ndk, bunkerUrl, localSigner)
+await remoteSigner.blockUntilReady()
+ndk.signer = remoteSigner
+```
+
+## Publish Event
+
+```typescript
+import { NDKEvent } from '@nostr-dev-kit/ndk'
+
+const event = new NDKEvent(ndk)
+event.kind = 1
+event.content = "Hello Nostr!"
+event.tags = [['t', 'nostr']]
+
+await event.sign()
+await event.publish()
+```
+
+## Query Events (One-time)
+
+```typescript
+const events = await ndk.fetchEvents({
+  kinds: [1],
+  authors: [pubkey],
+  limit: 50
+})
+
+// Convert Set to Array
+const eventArray = Array.from(events)
+```
+
+## Subscribe (Real-time)
+
+```typescript
+const sub = ndk.subscribe(
+  { kinds: [1], authors: [pubkey] },
+  { closeOnEose: false }
+)
+
+sub.on('event', (event) => {
+  console.log('New event:', event.content)
+})
+
+// Cleanup
+sub.stop()
+```
+
+## Get User Profile
+
+```typescript
+// By npub
+const user = ndk.getUser({ npub })
+const profile = await user.fetchProfile()
+
+// By hex pubkey
+const user = ndk.getUser({ hexpubkey: pubkey })
+const profile = await user.fetchProfile()
+
+// By NIP-05
+const user = await ndk.getUserFromNip05('user@domain.com')
+const profile = await user?.fetchProfile()
+```
+
+## Common Filters
+
+```typescript
+// By author
+{ kinds: [1], authors: [pubkey] }
+
+// By tag
+{ kinds: [1], '#p': [pubkey] }
+{ kinds: [30402], '#d': [productSlug] }
+
+// By time
+{ 
+  kinds: [1], 
+  since: Math.floor(Date.now() / 1000) - 86400,  // Last 24h
+  until: Math.floor(Date.now() / 1000)
+}
+
+// By event ID
+{ ids: [eventId] }
+
+// Multiple conditions
+{
+  kinds: [16, 17],
+  '#order': [orderId],
+  since: timestamp,
+  limit: 100
+}
+```
+
+## Tag Helpers
+
+```typescript
+// Get first tag value
+const orderId = event.tagValue('order')
+
+// Find specific tag
+const tag = event.tags.find(t => t[0] === 'payment')
+const value = tag?.[1]
+
+// Get all of one type
+const pTags = event.tags.filter(t => t[0] === 'p')
+
+// Common tag formats
+['p', pubkey]                          // Mention
+['e', eventId]                         // Event reference
+['t', 'nostr']                         // Hashtag
+['d', identifier]                      // Replaceable ID
+['a', '30402:pubkey:d-tag']           // Addressable reference
+```
+
+## Error Handling Pattern
+
+```typescript
+const ndk = ndkActions.getNDK()
+if (!ndk) throw new Error('NDK not initialized')
+
+const signer = ndk.signer
+if (!signer) throw new Error('No active signer')
+
+try {
+  await event.publish()
+} catch (error) {
+  console.error('Publish failed:', error)
+  throw error
+}
+```
+
+## React Integration
+
+```typescript
+// Query function
+export const fetchProducts = async (pubkey: string) => {
+  const ndk = ndkActions.getNDK()
+  if (!ndk) throw new Error('NDK not initialized')
+  
+  const events = await ndk.fetchEvents({
+    kinds: [30402],
+    authors: [pubkey]
+  })
+  
+  return Array.from(events)
+}
+
+// React Query hook
+export const useProducts = (pubkey: string) => {
+  return useQuery({
+    queryKey: ['products', pubkey],
+    queryFn: () => fetchProducts(pubkey),
+    enabled: !!pubkey,
+  })
+}
+
+// Subscription in useEffect
+useEffect(() => {
+  if (!ndk || !orderId) return
+  
+  const sub = ndk.subscribe(
+    { kinds: [16], '#order': [orderId] },
+    { closeOnEose: false }
+  )
+  
+  sub.on('event', () => {
+    queryClient.invalidateQueries(['order', orderId])
+  })
+  
+  return () => sub.stop()
+}, [ndk, orderId, queryClient])
+```
+
+## Common Event Kinds
+
+```typescript
+0     // Metadata (profile)
+1     // Text note
+4     // Encrypted DM (NIP-04)
+7     // Reaction
+9735  // Zap receipt
+10000 // Mute list
+10002 // Relay list
+30402 // Product listing (Marketplace)
+31990 // App handler (NIP-89)
+```
+
+## Relay Management
+
+```typescript
+// Check connection
+const connected = ndk.pool?.connectedRelays().length > 0
+
+// Get connected relays
+const relays = Array.from(ndk.pool?.relays.values() || [])
+  .filter(r => r.status === 1)
+
+// Add relay
+ndk.addExplicitRelay('wss://relay.example.com')
+```
+
+## Connection with Timeout
+
+```typescript
+const connectWithTimeout = async (timeoutMs = 10000) => {
+  const connectPromise = ndk.connect()
+  const timeoutPromise = new Promise((_, reject) =>
+    setTimeout(() => reject(new Error('Timeout')), timeoutMs)
+  )
+  
+  await Promise.race([connectPromise, timeoutPromise])
+}
+```
+
+## Current User
+
+```typescript
+// Active user
+const user = ndk.activeUser
+
+// From signer
+const user = await ndk.signer?.user()
+
+// User info
+const pubkey = user.pubkey  // hex
+const npub = user.npub      // NIP-19
+```
+
+## Parameterized Replaceable Events
+
+```typescript
+// Create
+const event = new NDKEvent(ndk)
+event.kind = 30402
+event.content = JSON.stringify(data)
+event.tags = [
+  ['d', uniqueIdentifier],  // Required for replaceable
+  ['title', 'Product Name'],
+]
+
+await event.sign()
+await event.publish()
+
+// Query (returns latest only)
+const events = await ndk.fetchEvents({
+  kinds: [30402],
+  authors: [pubkey],
+  '#d': [identifier]
+})
+```
+
+## Validation Checks
+
+```typescript
+// Event age check
+const now = Math.floor(Date.now() / 1000)
+const age = now - (event.created_at || 0)
+if (age > 86400) console.log('Event older than 24h')
+
+// Required fields
+if (!event.pubkey || !event.created_at || !event.sig) {
+  throw new Error('Invalid event')
+}
+
+// Tag existence
+const orderId = event.tagValue('order')
+if (!orderId) throw new Error('Missing order tag')
+```
+
+## Performance Tips
+
+```typescript
+// Batch queries
+const [products, orders] = await Promise.all([
+  ndk.fetchEvents(productFilter),
+  ndk.fetchEvents(orderFilter)
+])
+
+// Limit results
+const filter = {
+  kinds: [1],
+  limit: 50,
+  since: recentTimestamp
+}
+
+// Cache with React Query
+const { data } = useQuery({
+  queryKey: ['profile', npub],
+  queryFn: () => fetchProfile(npub),
+  staleTime: 5 * 60 * 1000,  // 5 min
+})
+```
+
+## Debugging
+
+```typescript
+// Check NDK state
+console.log('Connected:', ndk.pool?.connectedRelays())
+console.log('Signer:', ndk.signer)
+console.log('Active user:', ndk.activeUser)
+
+// Event inspection
+console.log('Event ID:', event.id)
+console.log('Tags:', event.tags)
+console.log('Content:', event.content)
+console.log('Author:', event.pubkey)
+
+// Subscription events
+sub.on('event', e => console.log('Event:', e))
+sub.on('eose', () => console.log('End of stored events'))
+```

+# NDK Common Patterns & Troubleshooting
+
+Quick reference for common patterns and solutions to frequent NDK issues.
+
+## Common Patterns
+
+### Store-Based NDK Management
+
+```typescript
+// Store pattern (recommended for React apps)
+import { Store } from '@tanstack/store'
+
+interface NDKState {
+  ndk: NDK | null
+  isConnected: boolean
+  signer?: NDKSigner
+}
+
+const ndkStore = new Store<NDKState>({
+  ndk: null,
+  isConnected: false
+})
+
+export const ndkActions = {
+  initialize: () => {
+    const ndk = new NDK({ explicitRelayUrls: relays })
+    ndkStore.setState({ ndk })
+    return ndk
+  },
+  
+  getNDK: () => ndkStore.state.ndk,
+  
+  setSigner: (signer: NDKSigner) => {
+    const ndk = ndkStore.state.ndk
+    if (ndk) {
+      ndk.signer = signer
+      ndkStore.setState({ signer })
+    }
+  }
+}
+```
+
+### Query + Subscription Pattern
+
+```typescript
+// Initial data load + real-time updates
+function useOrdersWithRealtime(orderId: string) {
+  const queryClient = useQueryClient()
+  const ndk = ndkActions.getNDK()
+  
+  // Fetch initial data
+  const query = useQuery({
+    queryKey: ['orders', orderId],
+    queryFn: () => fetchOrders(orderId),
+  })
+  
+  // Subscribe to updates
+  useEffect(() => {
+    if (!ndk || !orderId) return
+    
+    const sub = ndk.subscribe(
+      { kinds: [16], '#order': [orderId] },
+      { closeOnEose: false }
+    )
+    
+    sub.on('event', () => {
+      queryClient.invalidateQueries(['orders', orderId])
+    })
+    
+    return () => sub.stop()
+  }, [ndk, orderId])
+  
+  return query
+}
+```
+
+### Event Parsing Pattern
+
+```typescript
+// Parse event tags into structured data
+function parseProductEvent(event: NDKEvent) {
+  const getTag = (name: string) => 
+    event.tags.find(t => t[0] === name)?.[1]
+  
+  const getAllTags = (name: string) =>
+    event.tags.filter(t => t[0] === name).map(t => t[1])
+  
+  return {
+    id: event.id,
+    slug: getTag('d'),
+    title: getTag('title'),
+    price: parseFloat(getTag('price') || '0'),
+    currency: event.tags.find(t => t[0] === 'price')?.[2] || 'USD',
+    images: getAllTags('image'),
+    shipping: getAllTags('shipping'),
+    description: event.content,
+    createdAt: event.created_at,
+    author: event.pubkey
+  }
+}
+```
+
+### Relay Pool Pattern
+
+```typescript
+// Separate NDK instances for different purposes
+const mainNdk = new NDK({
+  explicitRelayUrls: ['wss://relay.damus.io', 'wss://nos.lol']
+})
+
+const zapNdk = new NDK({
+  explicitRelayUrls: ['wss://relay.damus.io']  // Zap-optimized relays
+})
+
+const blossomNdk = new NDK({
+  explicitRelayUrls: ['wss://blossom.server.com']  // Media server
+})
+
+await Promise.all([
+  mainNdk.connect(),
+  zapNdk.connect(),
+  blossomNdk.connect()
+])
+```
+
+## Troubleshooting
+
+### Problem: Events Not Received
+
+**Symptoms:** Subscription doesn't receive events, fetchEvents returns empty Set
+
+**Solutions:**
+
+1. Check relay connection:
+```typescript
+const status = ndk.pool?.connectedRelays()
+console.log('Connected relays:', status?.length)
+if (status?.length === 0) {
+  await ndk.connect()
+}
+```
+
+2. Verify filter syntax (especially tags):
+```typescript
+// ❌ Wrong
+{ kinds: [16], 'order': [orderId] }
+
+// ✅ Correct (note the # prefix for tags)
+{ kinds: [16], '#order': [orderId] }
+```
+
+3. Check timestamps:
+```typescript
+// Events might be too old/new
+const now = Math.floor(Date.now() / 1000)
+const filter = {
+  kinds: [1],
+  since: now - 86400,  // Last 24 hours
+  until: now
+}
+```
+
+4. Ensure closeOnEose is correct:
+```typescript
+// For real-time updates
+ndk.subscribe(filter, { closeOnEose: false })
+
+// For one-time historical fetch
+ndk.subscribe(filter, { closeOnEose: true })
+```
+
+### Problem: "NDK not initialized"
+
+**Symptoms:** `ndk` is null/undefined
+
+**Solutions:**
+
+1. Initialize before use:
+```typescript
+// In app entry point
+const ndk = new NDK({ explicitRelayUrls: relays })
+await ndk.connect()
+```
+
+2. Add null checks:
+```typescript
+const ndk = ndkActions.getNDK()
+if (!ndk) throw new Error('NDK not initialized')
+```
+
+3. Use initialization guard:
+```typescript
+const ensureNDK = () => {
+  let ndk = ndkActions.getNDK()
+  if (!ndk) {
+    ndk = ndkActions.initialize()
+  }
+  return ndk
+}
+```
+
+### Problem: "No active signer" / Cannot Sign Events
+
+**Symptoms:** Event signing fails, publishing throws error
+
+**Solutions:**
+
+1. Check signer is set:
+```typescript
+if (!ndk.signer) {
+  throw new Error('Please login first')
+}
+```
+
+2. Ensure blockUntilReady called:
+```typescript
+const signer = new NDKNip07Signer()
+await signer.blockUntilReady()  // ← Critical!
+ndk.signer = signer
+```
+
+3. Handle NIP-07 unavailable:
+```typescript
+try {
+  const signer = new NDKNip07Signer()
+  await signer.blockUntilReady()
+  ndk.signer = signer
+} catch (error) {
+  console.error('Browser extension not available')
+  // Fallback to other auth method
+}
+```
+
+### Problem: Duplicate Events in Subscriptions
+
+**Symptoms:** Same event received multiple times
+
+**Solutions:**
+
+1. Track processed event IDs:
+```typescript
+const processedIds = new Set<string>()
+
+sub.on('event', (event) => {
+  if (processedIds.has(event.id)) return
+  processedIds.add(event.id)
+  handleEvent(event)
+})
+```
+
+2. Use Map for event storage:
+```typescript
+const [events, setEvents] = useState<Map<string, NDKEvent>>(new Map())
+
+sub.on('event', (event) => {
+  setEvents(prev => new Map(prev).set(event.id, event))
+})
+```
+
+### Problem: Connection Timeout
+
+**Symptoms:** connect() hangs, never resolves
+
+**Solutions:**
+
+1. Use timeout wrapper:
+```typescript
+const connectWithTimeout = async (ndk: NDK, ms = 10000) => {
+  await Promise.race([
+    ndk.connect(),
+    new Promise((_, reject) =>
+      setTimeout(() => reject(new Error('Timeout')), ms)
+    )
+  ])
+}
+```
+
+2. Try fewer relays:
+```typescript
+// Start with reliable relays only
+const reliableRelays = ['wss://relay.damus.io']
+const ndk = new NDK({ explicitRelayUrls: reliableRelays })
+```
+
+3. Add connection retry:
+```typescript
+const connectWithRetry = async (ndk: NDK, maxRetries = 3) => {
+  for (let i = 0; i < maxRetries; i++) {
+    try {
+      await connectWithTimeout(ndk, 10000)
+      return
+    } catch (error) {
+      console.log(`Retry ${i + 1}/${maxRetries}`)
+      if (i === maxRetries - 1) throw error
+    }
+  }
+}
+```
+
+### Problem: Subscription Memory Leak
+
+**Symptoms:** App gets slower, memory usage increases
+
+**Solutions:**
+
+1. Always stop subscriptions:
+```typescript
+useEffect(() => {
+  const sub = ndk.subscribe(filter, { closeOnEose: false })
+  
+  // ← CRITICAL: cleanup
+  return () => {
+    sub.stop()
+  }
+}, [dependencies])
+```
+
+2. Track active subscriptions:
+```typescript
+const activeSubscriptions = new Set<NDKSubscription>()
+
+const createSub = (filter: NDKFilter) => {
+  const sub = ndk.subscribe(filter, { closeOnEose: false })
+  activeSubscriptions.add(sub)
+  return sub
+}
+
+const stopAllSubs = () => {
+  activeSubscriptions.forEach(sub => sub.stop())
+  activeSubscriptions.clear()
+}
+```
+
+### Problem: Profile Not Found
+
+**Symptoms:** fetchProfile() returns null/undefined
+
+**Solutions:**
+
+1. Check different relays:
+```typescript
+// Add more relay URLs
+const ndk = new NDK({
+  explicitRelayUrls: [
+    'wss://relay.damus.io',
+    'wss://relay.nostr.band',
+    'wss://nos.lol'
+  ]
+})
+```
+
+2. Verify pubkey format:
+```typescript
+// Ensure correct format
+if (pubkey.startsWith('npub')) {
+  const user = ndk.getUser({ npub: pubkey })
+} else if (/^[0-9a-f]{64}$/.test(pubkey)) {
+  const user = ndk.getUser({ hexpubkey: pubkey })
+}
+```
+
+3. Handle missing profiles gracefully:
+```typescript
+const profile = await user.fetchProfile()
+const displayName = profile?.name || profile?.displayName || 'Anonymous'
+const avatar = profile?.picture || '/default-avatar.png'
+```
+
+### Problem: Events Published But Not Visible
+
+**Symptoms:** publish() succeeds but event not found in queries
+
+**Solutions:**
+
+1. Verify event was signed:
+```typescript
+await event.sign()
+console.log('Event ID:', event.id)  // Should be set
+console.log('Signature:', event.sig)  // Should exist
+```
+
+2. Check relay acceptance:
+```typescript
+const relays = await event.publish()
+console.log('Published to relays:', relays)
+```
+
+3. Query immediately after publish:
+```typescript
+await event.publish()
+
+// Wait a moment for relay propagation
+await new Promise(resolve => setTimeout(resolve, 1000))
+
+const found = await ndk.fetchEvents({ ids: [event.id] })
+console.log('Event found:', found.size > 0)
+```
+
+### Problem: NIP-46 Connection Fails
+
+**Symptoms:** Remote signer connection times out or fails
+
+**Solutions:**
+
+1. Verify bunker URL format:
+```typescript
+// Correct format: bunker://<remote-pubkey>?relay=wss://...
+const isValidBunkerUrl = (url: string) => {
+  return url.startsWith('bunker://') && url.includes('?relay=')
+}
+```
+
+2. Ensure local signer is ready:
+```typescript
+const localSigner = new NDKPrivateKeySigner(privateKey)
+await localSigner.blockUntilReady()
+
+const remoteSigner = new NDKNip46Signer(ndk, bunkerUrl, localSigner)
+await remoteSigner.blockUntilReady()
+```
+
+3. Store credentials for reconnection:
+```typescript
+// Save for future sessions
+localStorage.setItem('local-signer-key', localSigner.privateKey)
+localStorage.setItem('bunker-url', bunkerUrl)
+```
+
+## Performance Tips
+
+### Optimize Queries
+
+```typescript
+// ❌ Slow: Multiple sequential queries
+const products = await ndk.fetchEvents({ kinds: [30402], authors: [pk1] })
+const orders = await ndk.fetchEvents({ kinds: [16], authors: [pk1] })
+const profiles = await ndk.fetchEvents({ kinds: [0], authors: [pk1] })
+
+// ✅ Fast: Parallel queries
+const [products, orders, profiles] = await Promise.all([
+  ndk.fetchEvents({ kinds: [30402], authors: [pk1] }),
+  ndk.fetchEvents({ kinds: [16], authors: [pk1] }),
+  ndk.fetchEvents({ kinds: [0], authors: [pk1] })
+])
+```
+
+### Cache Profile Lookups
+
+```typescript
+const profileCache = new Map<string, NDKUserProfile>()
+
+const getCachedProfile = async (ndk: NDK, pubkey: string) => {
+  if (profileCache.has(pubkey)) {
+    return profileCache.get(pubkey)!
+  }
+  
+  const user = ndk.getUser({ hexpubkey: pubkey })
+  const profile = await user.fetchProfile()
+  if (profile) {
+    profileCache.set(pubkey, profile)
+  }
+  
+  return profile
+}
+```
+
+### Limit Result Sets
+
+```typescript
+// Always use limit to prevent over-fetching
+const filter: NDKFilter = {
+  kinds: [1],
+  authors: [pubkey],
+  limit: 50  // ← Important!
+}
+```
+
+### Debounce Subscription Updates
+
+```typescript
+import { debounce } from 'lodash'
+
+const debouncedUpdate = debounce((event: NDKEvent) => {
+  handleEvent(event)
+}, 300)
+
+sub.on('event', debouncedUpdate)
+```
+
+## Testing Tips
+
+### Mock NDK in Tests
+
+```typescript
+const mockNDK = {
+  fetchEvents: vi.fn().mockResolvedValue(new Set()),
+  subscribe: vi.fn().mockReturnValue({
+    on: vi.fn(),
+    stop: vi.fn()
+  }),
+  signer: {
+    user: vi.fn().mockResolvedValue({ pubkey: 'test-pubkey' })
+  }
+} as unknown as NDK
+```
+
+### Test Event Creation
+
+```typescript
+const createTestEvent = (overrides?: Partial<NDKEvent>): NDKEvent => {
+  return {
+    id: 'test-id',
+    kind: 1,
+    content: 'test content',
+    tags: [],
+    created_at: Math.floor(Date.now() / 1000),
+    pubkey: 'test-pubkey',
+    sig: 'test-sig',
+    ...overrides
+  } as NDKEvent
+}
+```

+description: This skill should be used when implementing, debugging, or discussing WebSocket connections for Nostr relays. Provides comprehensive knowledge of RFC 6455 WebSocket protocol, production-ready implementation patterns in Go (khatru), C++ (strfry), and Rust (nostr-rs-relay), including connection lifecycle, message framing, subscription management, and performance optimization techniques specific to Nostr relay operations.
+---
+
+# Nostr WebSocket Programming
+
+## Overview
+
+Implement robust, high-performance WebSocket connections for Nostr relays following RFC 6455 specifications and battle-tested production patterns. This skill provides comprehensive guidance on WebSocket protocol fundamentals, connection management, message handling, and language-specific implementation strategies using proven codebases.
+
+## Core WebSocket Protocol (RFC 6455)
+
+### Connection Upgrade Handshake
+
+The WebSocket connection begins with an HTTP upgrade request:
+
+**Client Request Headers:**
+- `Upgrade: websocket` - Required
+- `Connection: Upgrade` - Required
+- `Sec-WebSocket-Key` - 16-byte random value, base64-encoded
+- `Sec-WebSocket-Version: 13` - Required
+- `Origin` - Required for browser clients (security)
+
+**Server Response (HTTP 101):**
+- `HTTP/1.1 101 Switching Protocols`
+- `Upgrade: websocket`
+- `Connection: Upgrade`
+- `Sec-WebSocket-Accept` - SHA-1(client_key + "258EAFA5-E914-47DA-95CA-C5AB0DC85B11"), base64-encoded
+
+**Security validation:** Always verify the `Sec-WebSocket-Accept` value matches expected computation. Reject connections with missing or incorrect values.
+
+### Frame Structure
+
+WebSocket frames use binary encoding with variable-length fields:
+
+**Header (minimum 2 bytes):**
+- **FIN bit** (1 bit) - Final fragment indicator
+- **RSV1-3** (3 bits) - Reserved for extensions (must be 0)
+- **Opcode** (4 bits) - Frame type identifier
+- **MASK bit** (1 bit) - Payload masking indicator
+- **Payload length** (7, 7+16, or 7+64 bits) - Variable encoding
+
+**Payload length encoding:**
+- 0-125: Direct 7-bit value
+- 126: Next 16 bits contain length
+- 127: Next 64 bits contain length
+
+### Frame Opcodes
+
+**Data Frames:**
+- `0x0` - Continuation frame
+- `0x1` - Text frame (UTF-8)
+- `0x2` - Binary frame
+
+**Control Frames:**
+- `0x8` - Connection close
+- `0x9` - Ping
+- `0xA` - Pong
+
+**Control frame constraints:**
+- Maximum 125-byte payload
+- Cannot be fragmented
+- Must be processed immediately
+
+### Masking Requirements
+
+**Critical security requirement:**
+- Client-to-server frames MUST be masked
+- Server-to-client frames MUST NOT be masked
+- Masking uses XOR with 4-byte random key
+- Prevents cache poisoning and intermediary attacks
+
+**Masking algorithm:**
+```
+transformed[i] = original[i] XOR masking_key[i MOD 4]
+```
+
+### Ping/Pong Keep-Alive
+
+**Purpose:** Detect broken connections and maintain NAT traversal
+
+**Pattern:**
+1. Either endpoint sends Ping (0x9) with optional payload
+2. Recipient responds with Pong (0xA) containing identical payload
+3. Implement timeouts to detect unresponsive connections
+
+**Nostr relay recommendations:**
+- Send pings every 30-60 seconds
+- Timeout after 60-120 seconds without pong response
+- Close connections exceeding timeout threshold
+
+### Close Handshake
+
+**Initiation:** Either peer sends Close frame (0x8)
+
+**Close frame structure:**
+- Optional 2-byte status code
+- Optional UTF-8 reason string
+
+**Common status codes:**
+- `1000` - Normal closure
+- `1001` - Going away (server shutdown/navigation)
+- `1002` - Protocol error
+- `1003` - Unsupported data type
+- `1006` - Abnormal closure (no close frame)
+- `1011` - Server error
+
+**Proper shutdown sequence:**
+1. Initiator sends Close frame
+2. Recipient responds with Close frame
+3. Both close TCP connection
+
+## Nostr Relay WebSocket Architecture
+
+### Message Flow Overview
+
+```
+Client                    Relay
+  |                         |
+  |--- HTTP Upgrade ------->|
+  |<-- 101 Switching -------|
+  |                         |
+  |--- ["EVENT", {...}] --->|  (Validate, store, broadcast)
+  |<-- ["OK", id, ...] -----|
+  |                         |
+  |--- ["REQ", id, {...}]-->|  (Query + subscribe)
+  |<-- ["EVENT", id, {...}]-|  (Stored events)
+  |<-- ["EOSE", id] --------|  (End of stored)
+  |<-- ["EVENT", id, {...}]-|  (Real-time events)
+  |                         |
+  |--- ["CLOSE", id] ------>|  (Unsubscribe)
+  |                         |
+  |--- Close Frame -------->|
+  |<-- Close Frame ---------|
+```
+
+### Critical Concurrency Considerations
+
+**Write concurrency:** WebSocket libraries panic/error on concurrent writes. Always protect writes with:
+- Mutex locks (Go, C++)
+- Single-writer goroutine/thread pattern
+- Message queue with dedicated sender
+
+**Read concurrency:** Concurrent reads generally allowed but not useful - implement single reader loop per connection.
+
+**Subscription management:** Concurrent access to subscription maps requires synchronization or lock-free data structures.
+
+## Language-Specific Implementation Patterns
+
+### Go Implementation (khatru-style)
+
+**Recommended library:** `github.com/fasthttp/websocket`
+
+**Connection structure:**
+```go
+type WebSocket struct {
+    conn   *websocket.Conn
+    mutex  sync.Mutex          // Protects writes
+
+    Request *http.Request      // Original HTTP request
+    Context context.Context    // Cancellation context
+    cancel  context.CancelFunc
+
+    // NIP-42 authentication
+    Challenge       string
+    AuthedPublicKey string
+
+    // Concurrent session management
+    negentropySessions *xsync.MapOf[string, *NegentropySession]
+}
+
+// Thread-safe write
+func (ws *WebSocket) WriteJSON(v any) error {
+    ws.mutex.Lock()
+    defer ws.mutex.Unlock()
+    return ws.conn.WriteJSON(v)
+}
+```
+
+**Lifecycle pattern (dual goroutines):**
+```go
+// Read goroutine
+go func() {
+    defer cleanup()
+
+    ws.conn.SetReadLimit(maxMessageSize)
+    ws.conn.SetReadDeadline(time.Now().Add(pongWait))
+    ws.conn.SetPongHandler(func(string) error {
+        ws.conn.SetReadDeadline(time.Now().Add(pongWait))
+        return nil
+    })
+
+    for {
+        typ, msg, err := ws.conn.ReadMessage()
+        if err != nil {
+            return  // Connection closed
+        }
+
+        if typ == websocket.PingMessage {
+            ws.WriteMessage(websocket.PongMessage, nil)
+            continue
+        }
+
+        // Parse and handle message in separate goroutine
+        go handleMessage(msg)
+    }
+}()
+
+// Write/ping goroutine
+go func() {
+    defer cleanup()
+    ticker := time.NewTicker(pingPeriod)
+    defer ticker.Stop()
+
+    for {
+        select {
+        case <-ctx.Done():
+            return
+        case <-ticker.C:
+            if err := ws.WriteMessage(websocket.PingMessage, nil); err != nil {
+                return
+            }
+        }
+    }
+}()
+```
+
+**Key patterns:**
+- **Mutex-protected writes** - Prevent concurrent write panics
+- **Context-based lifecycle** - Clean cancellation hierarchy
+- **Swap-delete for subscriptions** - O(1) removal from listener arrays
+- **Zero-copy string conversion** - `unsafe.String()` for message parsing
+- **Goroutine-per-message** - Sequential parsing, concurrent handling
+- **Hook-based extensibility** - Plugin architecture without core modifications
+
+**Configuration constants:**
+```go
+WriteWait:      10 * time.Second   // Write timeout
+PongWait:       60 * time.Second   // Pong timeout
+PingPeriod:     30 * time.Second   // Ping interval (< PongWait)
+MaxMessageSize: 512000             // 512 KB limit
+```
+
+**Subscription management:**
+```go
+type listenerSpec struct {
+    id       string
+    cancel   context.CancelCauseFunc
+    index    int
+    subrelay *Relay
+}
+
+// Efficient removal with swap-delete
+func (rl *Relay) removeListenerId(ws *WebSocket, id string) {
+    rl.clientsMutex.Lock()
+    defer rl.clientsMutex.Unlock()
+
+    if specs, ok := rl.clients[ws]; ok {
+        for i := len(specs) - 1; i >= 0; i-- {
+            if specs[i].id == id {
+                specs[i].cancel(ErrSubscriptionClosedByClient)
+                specs[i] = specs[len(specs)-1]
+                specs = specs[:len(specs)-1]
+                rl.clients[ws] = specs
+                break
+            }
+        }
+    }
+}
+```

+
+### C++ Implementation (strfry-style)
+
+**Recommended library:** Custom fork of `uWebSockets` with epoll
+
+**Architecture highlights:**
+- Single-threaded I/O using epoll for connection multiplexing
+- Thread pool architecture: 6 specialized pools (WebSocket, Ingester, Writer, ReqWorker, ReqMonitor, Negentropy)
+- "Shared nothing" message-passing design eliminates lock contention
+- Deterministic thread assignment: `connId % numThreads`
+
+**Connection structure:**
+```cpp
+struct ConnectionState {
+    uint64_t connId;
+    std::string remoteAddr;
+    flat_str subId;              // Subscription ID
+    std::shared_ptr<Subscription> sub;
+    PerMessageDeflate pmd;       // Compression state
+    uint64_t latestEventSent = 0;
+
+    // Message parsing state
+    secp256k1_context *secpCtx;
+    std::string parseBuffer;
+};
+```
+
+**Message handling pattern:**
+```cpp
+// WebSocket message callback
+ws->onMessage([=](std::string_view msg, uWS::OpCode opCode) {
+    // Reuse buffer to avoid allocations
+    state->parseBuffer.assign(msg.data(), msg.size());
+
+    try {
+        auto json = nlohmann::json::parse(state->parseBuffer);
+        auto cmdStr = json[0].get<std::string>();
+
+        if (cmdStr == "EVENT") {
+            // Send to Ingester thread pool
+            auto packed = MsgIngester::Message(connId, std::move(json));
+            tpIngester->dispatchToThread(connId, std::move(packed));
+        }
+        else if (cmdStr == "REQ") {
+            // Send to ReqWorker thread pool
+            auto packed = MsgReq::Message(connId, std::move(json));
+            tpReqWorker->dispatchToThread(connId, std::move(packed));
+        }
+    } catch (std::exception &e) {
+        sendNotice("Error: " + std::string(e.what()));
+    }
+});
+```
+
+**Critical performance optimizations:**
+
+1. **Event batching** - Serialize event JSON once, reuse for thousands of subscribers:
+```cpp
+// Single serialization
+std::string eventJson = event.toJson();
+
+// Broadcast to all matching subscriptions
+for (auto &[connId, sub] : activeSubscriptions) {
+    if (sub->matches(event)) {
+        sendToConnection(connId, eventJson);  // Reuse serialized JSON
+    }
+}
+```
+
+2. **Move semantics** - Zero-copy message passing:
+```cpp
+tpIngester->dispatchToThread(connId, std::move(message));
+```
+
+3. **Pre-allocated buffers** - Single reusable buffer per connection:
+```cpp
+state->parseBuffer.assign(msg.data(), msg.size());
+```
+
+4. **std::variant dispatch** - Type-safe without virtual function overhead:
+```cpp
+std::variant<MsgReq, MsgIngester, MsgWriter> message;
+std::visit([](auto&& msg) { msg.handle(); }, message);
+```

+### Rust Implementation (nostr-rs-relay-style)
+
+**Recommended libraries:**
+- `tokio-tungstenite 0.17` - Async WebSocket support
+- `tokio 1.x` - Async runtime
+- `serde_json` - Message parsing
+
+**WebSocket configuration:**
+```rust
+let config = WebSocketConfig {
+    max_send_queue: Some(1024),
+    max_message_size: settings.limits.max_ws_message_bytes,
+    max_frame_size: settings.limits.max_ws_frame_bytes,
+    ..Default::default()
+};
+
+let ws_stream = WebSocketStream::from_raw_socket(
+    upgraded,
+    Role::Server,
+    Some(config),
+).await;
+```
+
+**Connection state:**
+```rust
+pub struct ClientConn {
+    client_ip_addr: String,
+    client_id: Uuid,
+    subscriptions: HashMap<String, Subscription>,
+    max_subs: usize,
+    auth: Nip42AuthState,
+}
+
+pub enum Nip42AuthState {
+    NoAuth,
+    Challenge(String),
+    AuthPubkey(String),
+}
+```
+
+**Async message loop with tokio::select!:**
+```rust
+async fn nostr_server(
+    repo: Arc<dyn NostrRepo>,
+    mut ws_stream: WebSocketStream<Upgraded>,
+    broadcast: Sender<Event>,
+    mut shutdown: Receiver<()>,
+) {
+    let mut conn = ClientConn::new(client_ip);
+    let mut bcast_rx = broadcast.subscribe();

+
+    loop {
+        tokio::select! {
+            // Handle shutdown
+            _ = shutdown.recv() => { break; }
+
+            // Send periodic pings
+            _ = ping_interval.tick() => {
+                ws_stream.send(Message::Ping(Vec::new())).await.ok();
+            }
+
+            // Handle broadcast events (real-time)
+            Ok(event) = bcast_rx.recv() => {
+                for (id, sub) in conn.subscriptions() {
+                    if sub.interested_in_event(&event) {
+                        let msg = format!("[\"EVENT\",\"{}\",{}]", id,
+                                         serde_json::to_string(&event)?);
+                        ws_stream.send(Message::Text(msg)).await.ok();
+                    }
+                }
+            }
+
+            // Handle incoming client messages
+            Some(result) = ws_stream.next() => {
+                match result {
+                    Ok(Message::Text(msg)) => {
+                        handle_nostr_message(&msg, &mut conn).await;
+                    }
+                    Ok(Message::Binary(_)) => {
+                        send_notice("binary messages not accepted").await;
+                    }
+                    Ok(Message::Ping(_) | Message::Pong(_)) => {
+                        continue;  // Auto-handled by tungstenite
+                    }
+                    Ok(Message::Close(_)) | Err(_) => {
+                        break;
+                    }
+                    _ => {}
+                }
+            }
+        }
+    }
+}
+```
+
+**Subscription filtering:**
+```rust
+pub struct ReqFilter {
+    pub ids: Option<Vec<String>>,
+    pub kinds: Option<Vec<u64>>,
+    pub since: Option<u64>,
+    pub until: Option<u64>,
+    pub authors: Option<Vec<String>>,
+    pub limit: Option<u64>,
+    pub tags: Option<HashMap<char, HashSet<String>>>,
+}
+
+impl ReqFilter {
+    pub fn interested_in_event(&self, event: &Event) -> bool {
+        self.ids_match(event)
+            && self.since.map_or(true, |t| event.created_at >= t)
+            && self.until.map_or(true, |t| event.created_at <= t)
+            && self.kind_match(event.kind)
+            && self.authors_match(event)
+            && self.tag_match(event)
+    }
+
+    fn ids_match(&self, event: &Event) -> bool {
+        self.ids.as_ref()
+            .map_or(true, |ids| ids.iter().any(|id| event.id.starts_with(id)))
+    }
+}
+```
+
+**Error handling:**
+```rust
+match ws_stream.next().await {
+    Some(Ok(Message::Text(msg))) => { /* handle */ }
+
+    Some(Err(WsError::Capacity(MessageTooLong{size, max_size}))) => {

+        continue;
+    }
+
+    None | Some(Ok(Message::Close(_))) => {
+        info!("client closed connection");
+        break;
+    }
+
+    Some(Err(WsError::Io(e))) => {
+        warn!("IO error: {:?}", e);
+        break;
+    }
+
+    _ => { break; }
+}
+```

+
+## Common Implementation Patterns
+
+### Pattern 1: Dual Goroutine/Task Architecture
+
+**Purpose:** Separate read and write concerns, enable ping/pong management
+
+**Structure:**
+- **Reader goroutine/task:** Blocks on `ReadMessage()`, handles incoming frames
+- **Writer goroutine/task:** Sends periodic pings, processes outgoing message queue
+
+**Benefits:**
+- Natural separation of concerns
+- Ping timer doesn't block message processing
+- Clean shutdown coordination via context/channels
+
+### Pattern 2: Subscription Lifecycle
+
+**Create subscription (REQ):**
+1. Parse filter from client message
+2. Query database for matching stored events
+3. Send stored events to client
+4. Send EOSE (End of Stored Events)
+5. Add subscription to active listeners for real-time events
+
+**Handle real-time event:**
+1. Check all active subscriptions
+2. For each matching subscription:
+   - Apply filter matching logic
+   - Send EVENT message to client
+3. Track broadcast count for monitoring
+
+**Close subscription (CLOSE):**
+1. Find subscription by ID
+2. Cancel subscription context
+3. Remove from active listeners
+4. Clean up resources
+
+### Pattern 3: Write Serialization
+
+**Problem:** Concurrent writes cause panics/errors in WebSocket libraries
+
+**Solutions:**
+
+**Mutex approach (Go, C++):**
+```go
+func (ws *WebSocket) WriteJSON(v any) error {
+    ws.mutex.Lock()
+    defer ws.mutex.Unlock()
+    return ws.conn.WriteJSON(v)
+}
+```
+
+**Single-writer goroutine (Alternative):**
+```go
+type writeMsg struct {
+    data []byte
+    done chan error
+}
+
+go func() {
+    for msg := range writeChan {
+        msg.done <- ws.conn.WriteMessage(websocket.TextMessage, msg.data)
+    }
+}()
+```
+
+### Pattern 4: Connection Cleanup
+
+**Essential cleanup steps:**
+1. Cancel all subscription contexts
+2. Stop ping ticker/interval
+3. Remove connection from active clients map
+4. Close WebSocket connection
+5. Close TCP connection
+6. Log connection statistics
+
+**Go cleanup function:**
+```go
+kill := func() {
+    // Cancel contexts
+    cancel()
+    ws.cancel()
+
+    // Stop timers
+    ticker.Stop()
+
+    // Remove from tracking
+    rl.removeClientAndListeners(ws)
+
+    // Close connection
+    ws.conn.Close()
+
+    // Trigger hooks
+    for _, ondisconnect := range rl.OnDisconnect {
+        ondisconnect(ctx)
+    }
+}
+defer kill()
+```
+
+### Pattern 5: Event Broadcasting Optimization
+
+**Naive approach (inefficient):**
+```go
+// DON'T: Serialize for each subscriber
+for _, listener := range listeners {
+    if listener.filter.Matches(event) {
+        json := serializeEvent(event)  // Repeated work!
+        listener.ws.WriteJSON(json)
+    }
+}
+```
+
+**Optimized approach:**
+```go
+// DO: Serialize once, reuse for all subscribers
+eventJSON, err := json.Marshal(event)
+if err != nil {
+    return
+}
+
+for _, listener := range listeners {
+    if listener.filter.Matches(event) {
+        listener.ws.WriteMessage(websocket.TextMessage, eventJSON)
+    }
+}
+```
+
+**Savings:** For 1000 subscribers, reduces 1000 JSON serializations to 1.
+
+## Security Considerations
+
+### Origin Validation
+
+Always validate the `Origin` header for browser-based clients:
+
+```go
+upgrader := websocket.Upgrader{
+    CheckOrigin: func(r *http.Request) bool {
+        origin := r.Header.Get("Origin")
+        return isAllowedOrigin(origin)  // Implement allowlist
+    },
+}
+```
+
+**Default behavior:** Most libraries reject all cross-origin connections. Override with caution.
+
+### Rate Limiting
+
+Implement rate limits for:
+- Connection establishment (per IP)
+- Message throughput (per connection)
+- Subscription creation (per connection)
+- Event publication (per connection, per pubkey)
+
+```go
+// Example: Connection rate limiting
+type rateLimiter struct {
+    connections map[string]*rate.Limiter
+    mu          sync.Mutex
+}
+
+func (rl *Relay) checkRateLimit(ip string) bool {
+    limiter := rl.rateLimiter.getLimiter(ip)
+    return limiter.Allow()
+}
+```
+
+### Message Size Limits
+
+Configure limits to prevent memory exhaustion:
+
+```go
+ws.conn.SetReadLimit(maxMessageSize)  // e.g., 512 KB
+```
+
+```rust
+max_message_size: Some(512_000),
+max_frame_size: Some(16_384),
+```
+
+### Subscription Limits
+
+Prevent resource exhaustion:
+- Max subscriptions per connection (typically 10-20)
+- Max subscription ID length (prevent hash collision attacks)
+- Require specific filters (prevent full database scans)
+
+```rust
+const MAX_SUBSCRIPTION_ID_LEN: usize = 256;
+const MAX_SUBS_PER_CLIENT: usize = 20;
+
+if subscriptions.len() >= MAX_SUBS_PER_CLIENT {
+    return Err(Error::SubMaxExceededError);
+}
+```
+
+### Authentication (NIP-42)
+
+Implement challenge-response authentication:
+
+1. **Generate challenge on connect:**
+```go
+challenge := make([]byte, 8)
+rand.Read(challenge)
+ws.Challenge = hex.EncodeToString(challenge)
+```
+
+2. **Send AUTH challenge when required:**
+```json
+["AUTH", "<challenge>"]
+```
+
+3. **Validate AUTH event:**
+```go
+func validateAuthEvent(event *Event, challenge, relayURL string) bool {
+    // Check kind 22242
+    if event.Kind != 22242 { return false }
+
+    // Check challenge in tags
+    if !hasTag(event, "challenge", challenge) { return false }
+
+    // Check relay URL
+    if !hasTag(event, "relay", relayURL) { return false }
+
+    // Check timestamp (within 10 minutes)
+    if abs(time.Now().Unix() - event.CreatedAt) > 600 { return false }
+
+    // Verify signature
+    return event.CheckSignature()
+}
+```
+
+## Performance Optimization Techniques
+
+### 1. Connection Pooling
+
+Reuse connections for database queries:
+```go
+db, _ := sql.Open("postgres", dsn)
+db.SetMaxOpenConns(25)
+db.SetMaxIdleConns(5)
+db.SetConnMaxLifetime(5 * time.Minute)
+```
+
+### 2. Event Caching
+
+Cache frequently accessed events:
+```go
+type EventCache struct {
+    cache *lru.Cache
+    mu    sync.RWMutex
+}
+
+func (ec *EventCache) Get(id string) (*Event, bool) {
+    ec.mu.RLock()
+    defer ec.mu.RUnlock()
+    if val, ok := ec.cache.Get(id); ok {
+        return val.(*Event), true
+    }
+    return nil, false
+}
+```
+
+### 3. Batch Database Queries
+
+Execute queries concurrently for multi-filter subscriptions:
+```go
+var wg sync.WaitGroup
+for _, filter := range filters {
+    wg.Add(1)
+    go func(f Filter) {
+        defer wg.Done()
+        events := queryDatabase(f)
+        sendEvents(events)
+    }(filter)
+}
+wg.Wait()
+sendEOSE()
+```
+
+### 4. Compression (permessage-deflate)
+
+Enable WebSocket compression for text frames:
+```go
+upgrader := websocket.Upgrader{
+    EnableCompression: true,
+}
+```
+
+**Typical savings:** 60-80% bandwidth reduction for JSON messages
+
+**Trade-off:** Increased CPU usage (usually worthwhile)
+
+### 5. Monitoring and Metrics
+
+Track key performance indicators:
+- Connections (active, total, per IP)
+- Messages (received, sent, per type)
+- Events (stored, broadcast, per second)
+- Subscriptions (active, per connection)
+- Query latency (p50, p95, p99)
+- Database pool utilization
+
+```go
+// Prometheus-style metrics
+type Metrics struct {
+    Connections    prometheus.Gauge
+    MessagesRecv   prometheus.Counter
+    MessagesSent   prometheus.Counter
+    EventsStored   prometheus.Counter
+    QueryDuration  prometheus.Histogram
+}
+```
+
+## Testing WebSocket Implementations
+
+### Unit Testing
+
+Test individual components in isolation:
+
+```go
+func TestFilterMatching(t *testing.T) {
+    filter := Filter{
+        Kinds: []int{1, 3},
+        Authors: []string{"abc123"},
+    }
+
+    event := &Event{
+        Kind: 1,
+        PubKey: "abc123",
+    }
+
+    if !filter.Matches(event) {
+        t.Error("Expected filter to match event")
+    }
+}
+```
+
+### Integration Testing
+
+Test WebSocket connection handling:
+
+```go
+func TestWebSocketConnection(t *testing.T) {
+    // Start test server
+    server := startTestRelay(t)
+    defer server.Close()
+
+    // Connect client
+    ws, _, err := websocket.DefaultDialer.Dial(server.URL, nil)
+    if err != nil {
+        t.Fatalf("Failed to connect: %v", err)
+    }
+    defer ws.Close()
+
+    // Send REQ
+    req := `["REQ","test",{"kinds":[1]}]`
+    if err := ws.WriteMessage(websocket.TextMessage, []byte(req)); err != nil {
+        t.Fatalf("Failed to send REQ: %v", err)
+    }
+
+    // Read EOSE
+    _, msg, err := ws.ReadMessage()
+    if err != nil {
+        t.Fatalf("Failed to read message: %v", err)
+    }
+
+    if !strings.Contains(string(msg), "EOSE") {
+        t.Errorf("Expected EOSE, got: %s", msg)
+    }
+}
+```
+
+### Load Testing
+
+Use tools like `websocat` or custom scripts:
+
+```bash
+# Connect 1000 concurrent clients
+for i in {1..1000}; do
+    (websocat "ws://localhost:8080" <<< '["REQ","test",{"kinds":[1]}]' &)
+done
+```
+
+Monitor server metrics during load testing:
+- CPU usage
+- Memory consumption
+- Connection count
+- Message throughput
+- Database query rate
+
+## Debugging and Troubleshooting
+
+### Common Issues
+
+**1. Concurrent write panic/error**
+
+**Symptom:** `concurrent write to websocket connection` error
+
+**Solution:** Ensure all writes protected by mutex or use single-writer pattern
+
+**2. Connection timeouts**
+
+**Symptom:** Connections close after 60 seconds
+
+**Solution:** Implement ping/pong mechanism properly:
+```go
+ws.SetPongHandler(func(string) error {
+    ws.SetReadDeadline(time.Now().Add(pongWait))
+    return nil
+})
+```
+
+**3. Memory leaks**
+
+**Symptom:** Memory usage grows over time
+
+**Common causes:**
+- Subscriptions not removed on disconnect
+- Event channels not closed
+- Goroutines not terminated
+
+**Solution:** Ensure cleanup function called on disconnect
+
+**4. Slow subscription queries**
+
+**Symptom:** EOSE delayed by seconds
+
+**Solution:**
+- Add database indexes on filtered columns
+- Implement query timeouts
+- Consider caching frequently accessed events
+
+### Logging Best Practices
+
+Log critical events with context:
+
+```go
+log.Printf(
+    "connection closed: cid=%s ip=%s duration=%v sent=%d recv=%d",
+    conn.ID,
+    conn.IP,
+    time.Since(conn.ConnectedAt),
+    conn.EventsSent,
+    conn.EventsRecv,
+)
+```
+
+Use log levels appropriately:
+- **DEBUG:** Message parsing, filter matching
+- **INFO:** Connection lifecycle, subscription changes
+- **WARN:** Rate limit violations, invalid messages
+- **ERROR:** Database errors, unexpected panics

+# C++ WebSocket Implementation for Nostr Relays (strfry patterns)
+
+This reference documents high-performance WebSocket patterns from the strfry Nostr relay implementation in C++.
+
+## Repository Information
+
+- **Project:** strfry - High-performance Nostr relay
+- **Repository:** https://github.com/hoytech/strfry
+- **Language:** C++ (C++20)
+- **WebSocket Library:** Custom fork of uWebSockets with epoll
+- **Architecture:** Single-threaded I/O with specialized thread pools
+
+## Core Architecture
+
+### Thread Pool Design
+
+strfry uses 6 specialized thread pools for different operations:
+
+```
+┌─────────────────────────────────────────────────────────────┐

+
+**Thread Pool Responsibilities:**
+
+1. **WebSocket (1 thread):** Main I/O loop, epoll event handling
+2. **Ingester (3 threads):** Event validation, signature verification, deduplication
+3. **Writer (1 thread):** Database writes, event storage
+4. **ReqWorker (3 threads):** Process REQ subscriptions, query database
+5. **ReqMonitor (3 threads):** Monitor active subscriptions, send real-time events
+6. **Negentropy (2 threads):** NIP-77 set reconciliation
+
+**Deterministic thread assignment:**
+```cpp
+int threadId = connId % numThreads;
+```
+
+**Benefits:**
+- **No lock contention:** Shared-nothing architecture
+- **Predictable performance:** Same connection always same thread
+- **CPU cache efficiency:** Thread-local data stays hot
+
+### Connection State
+
+```cpp
+struct ConnectionState {
+    uint64_t connId;                  // Unique connection identifier
+    std::string remoteAddr;           // Client IP address
+
+    // Subscription state
+    flat_str subId;                   // Current subscription ID
+    std::shared_ptr<Subscription> sub; // Subscription filter
+    uint64_t latestEventSent = 0;     // Latest event ID sent
+
+    // Compression state (per-message deflate)
+    PerMessageDeflate pmd;
+
+    // Parsing state (reused buffer)
+    std::string parseBuffer;
+
+    // Signature verification context (reused)
+    secp256k1_context *secpCtx;
+};
+```
+
+**Key design decisions:**
+
+1. **Reusable parseBuffer:** Single allocation per connection
+2. **Persistent secp256k1_context:** Expensive to create, reused for all signatures
+3. **Connection ID:** Enables deterministic thread assignment
+4. **Flat string (flat_str):** Value-semantic string-like type for zero-copy
+
+## WebSocket Message Reception
+
+### Main Event Loop (epoll)
+
+```cpp
+// Pseudocode representation of strfry's I/O loop
+uWS::App app;
+
+app.ws<ConnectionState>("/*", {
+    .compression = uWS::SHARED_COMPRESSOR,
+    .maxPayloadLength = 16 * 1024 * 1024,
+    .idleTimeout = 120,
+    .maxBackpressure = 1 * 1024 * 1024,
+
+    .upgrade = nullptr,
+
+    .open = [](auto *ws) {
+        auto *state = ws->getUserData();
+        state->connId = nextConnId++;
+        state->remoteAddr = getRemoteAddress(ws);
+        state->secpCtx = secp256k1_context_create(SECP256K1_CONTEXT_VERIFY);
+
+        LI << "New connection: " << state->connId << " from " << state->remoteAddr;
+    },
+
+    .message = [](auto *ws, std::string_view message, uWS::OpCode opCode) {
+        auto *state = ws->getUserData();
+
+        // Reuse parseBuffer to avoid allocation
+        state->parseBuffer.assign(message.data(), message.size());
+
+        try {
+            // Parse JSON (nlohmann::json)
+            auto json = nlohmann::json::parse(state->parseBuffer);
+
+            // Extract command type
+            auto cmdStr = json[0].get<std::string>();
+
+            if (cmdStr == "EVENT") {
+                handleEventMessage(ws, std::move(json));
+            }
+            else if (cmdStr == "REQ") {
+                handleReqMessage(ws, std::move(json));
+            }
+            else if (cmdStr == "CLOSE") {
+                handleCloseMessage(ws, std::move(json));
+            }
+            else if (cmdStr == "NEG-OPEN") {
+                handleNegentropyOpen(ws, std::move(json));
+            }
+            else {
+                sendNotice(ws, "unknown command: " + cmdStr);
+            }
+        }
+        catch (std::exception &e) {
+            sendNotice(ws, "Error: " + std::string(e.what()));
+        }
+    },
+
+    .close = [](auto *ws, int code, std::string_view message) {
+        auto *state = ws->getUserData();
+
+        LI << "Connection closed: " << state->connId
+           << " code=" << code
+           << " msg=" << std::string(message);
+
+        // Cleanup
+        secp256k1_context_destroy(state->secpCtx);
+        cleanupSubscription(state->connId);
+    },
+});
+
+app.listen(8080, [](auto *token) {
+    if (token) {
+        LI << "Listening on port 8080";
+    }
+});
+
+app.run();
+```
+
+**Key patterns:**
+
+1. **epoll-based I/O:** Single thread handles thousands of connections
+2. **Buffer reuse:** `state->parseBuffer` avoids allocation per message
+3. **Move semantics:** `std::move(json)` transfers ownership to handler
+4. **Exception handling:** Catches parsing errors, sends NOTICE
+
+### Message Dispatch to Thread Pools
+
+```cpp
+void handleEventMessage(auto *ws, nlohmann::json &&json) {
+    auto *state = ws->getUserData();
+
+    // Pack message with connection ID
+    auto msg = MsgIngester{
+        .connId = state->connId,
+        .payload = std::move(json),
+    };
+
+    // Dispatch to Ingester thread pool (deterministic assignment)
+    tpIngester->dispatchToThread(state->connId, std::move(msg));
+}
+
+void handleReqMessage(auto *ws, nlohmann::json &&json) {
+    auto *state = ws->getUserData();
+
+    // Pack message
+    auto msg = MsgReq{
+        .connId = state->connId,
+        .payload = std::move(json),
+    };
+
+    // Dispatch to ReqWorker thread pool
+    tpReqWorker->dispatchToThread(state->connId, std::move(msg));
+}
+```
+
+**Message passing pattern:**
+
+```cpp
+// ThreadPool::dispatchToThread
+void dispatchToThread(uint64_t connId, Message &&msg) {
+    size_t threadId = connId % threads.size();
+    threads[threadId]->queue.push(std::move(msg));
+}
+```
+
+**Benefits:**
+- **Zero-copy:** `std::move` transfers ownership without copying
+- **Deterministic:** Same connection always processed by same thread
+- **Lock-free:** Each thread has own queue
+
+## Event Ingestion Pipeline
+
+### Ingester Thread Pool
+
+```cpp
+void IngesterThread::run() {
+    while (running) {
+        Message msg;
+        if (!queue.pop(msg, 100ms)) continue;
+
+        // Extract event from JSON
+        auto event = parseEvent(msg.payload);
+
+        // Validate event ID
+        if (!validateEventId(event)) {
+            sendOK(msg.connId, event.id, false, "invalid: id mismatch");
+            continue;
+        }
+
+        // Verify signature (using thread-local secp256k1 context)
+        if (!verifySignature(event, secpCtx)) {
+            sendOK(msg.connId, event.id, false, "invalid: signature verification failed");
+            continue;
+        }
+
+        // Check for duplicate (bloom filter + database)
+        if (isDuplicate(event.id)) {
+            sendOK(msg.connId, event.id, true, "duplicate: already have this event");
+            continue;
+        }
+
+        // Send to Writer thread
+        auto writerMsg = MsgWriter{
+            .connId = msg.connId,
+            .event = std::move(event),
+        };
+        tpWriter->dispatch(std::move(writerMsg));
+    }
+}
+```
+
+**Validation sequence:**
+1. Parse JSON into Event struct
+2. Validate event ID matches content hash
+3. Verify secp256k1 signature
+4. Check duplicate (bloom filter for speed)
+5. Forward to Writer thread for storage
+
+### Writer Thread
+
+```cpp
+void WriterThread::run() {
+    // Single thread for all database writes
+    while (running) {
+        Message msg;
+        if (!queue.pop(msg, 100ms)) continue;
+
+        // Write to database
+        bool success = db.insertEvent(msg.event);
+
+        // Send OK to client
+        sendOK(msg.connId, msg.event.id, success,
+               success ? "" : "error: failed to store");
+
+        if (success) {
+            // Broadcast to subscribers
+            broadcastEvent(msg.event);
+        }
+    }
+}
+```
+
+**Single-writer pattern:**
+- Only one thread writes to database
+- Eliminates write conflicts
+- Simplified transaction management
+
+### Event Broadcasting
+
+```cpp
+void broadcastEvent(const Event &event) {
+    // Serialize event JSON once
+    std::string eventJson = serializeEvent(event);
+
+    // Iterate all active subscriptions
+    for (auto &[connId, sub] : activeSubscriptions) {
+        // Check if filter matches
+        if (!sub->filter.matches(event)) continue;
+
+        // Check if event newer than last sent
+        if (event.id <= sub->latestEventSent) continue;
+
+        // Send to connection
+        auto msg = MsgWebSocket{
+            .connId = connId,
+            .payload = eventJson,  // Reuse serialized JSON
+        };
+
+        tpWebSocket->dispatch(std::move(msg));
+
+        // Update latest sent
+        sub->latestEventSent = event.id;
+    }
+}
+```
+
+**Critical optimization:** Serialize event JSON once, send to N subscribers
+
+**Performance impact:** For 1000 subscribers, reduces:
+- JSON serialization: 1000× → 1×
+- Memory allocations: 1000× → 1×
+- CPU time: ~100ms → ~1ms
+
+## Subscription Management
+
+### REQ Processing
+
+```cpp
+void ReqWorkerThread::run() {
+    while (running) {
+        MsgReq msg;
+        if (!queue.pop(msg, 100ms)) continue;
+
+        // Parse REQ message: ["REQ", subId, filter1, filter2, ...]
+        std::string subId = msg.payload[1];
+
+        // Create subscription object
+        auto sub = std::make_shared<Subscription>();
+        sub->subId = subId;
+
+        // Parse filters
+        for (size_t i = 2; i < msg.payload.size(); i++) {
+            Filter filter = parseFilter(msg.payload[i]);
+            sub->filters.push_back(filter);
+        }
+
+        // Store subscription
+        activeSubscriptions[msg.connId] = sub;
+
+        // Query stored events
+        std::vector<Event> events = db.queryEvents(sub->filters);
+
+        // Send matching events
+        for (const auto &event : events) {
+            sendEvent(msg.connId, subId, event);
+        }
+
+        // Send EOSE
+        sendEOSE(msg.connId, subId);
+
+        // Notify ReqMonitor to watch for real-time events
+        auto monitorMsg = MsgReqMonitor{
+            .connId = msg.connId,
+            .subId = subId,
+        };
+        tpReqMonitor->dispatchToThread(msg.connId, std::move(monitorMsg));
+    }
+}
+```
+
+**Query optimization:**
+
+```cpp
+std::vector<Event> Database::queryEvents(const std::vector<Filter> &filters) {
+    // Combine filters with OR logic
+    std::string sql = "SELECT * FROM events WHERE ";
+
+    for (size_t i = 0; i < filters.size(); i++) {
+        if (i > 0) sql += " OR ";
+        sql += buildFilterSQL(filters[i]);
+    }
+
+    sql += " ORDER BY created_at DESC LIMIT 1000";
+
+    return executeQuery(sql);
+}
+```
+
+**Filter SQL generation:**
+
+```cpp
+std::string buildFilterSQL(const Filter &filter) {
+    std::vector<std::string> conditions;
+
+    // Event IDs
+    if (!filter.ids.empty()) {
+        conditions.push_back("id IN (" + joinQuoted(filter.ids) + ")");
+    }
+
+    // Authors
+    if (!filter.authors.empty()) {
+        conditions.push_back("pubkey IN (" + joinQuoted(filter.authors) + ")");
+    }
+
+    // Kinds
+    if (!filter.kinds.empty()) {
+        conditions.push_back("kind IN (" + join(filter.kinds) + ")");
+    }
+
+    // Time range
+    if (filter.since) {
+        conditions.push_back("created_at >= " + std::to_string(*filter.since));
+    }
+    if (filter.until) {
+        conditions.push_back("created_at <= " + std::to_string(*filter.until));
+    }
+
+    // Tags (requires JOIN with tags table)
+    if (!filter.tags.empty()) {
+        for (const auto &[tagName, tagValues] : filter.tags) {
+            conditions.push_back(
+                "EXISTS (SELECT 1 FROM tags WHERE tags.event_id = events.id "
+                "AND tags.name = '" + tagName + "' "
+                "AND tags.value IN (" + joinQuoted(tagValues) + "))"
+            );
+        }
+    }
+
+    return "(" + join(conditions, " AND ") + ")";
+}
+```
+
+### ReqMonitor for Real-Time Events
+
+```cpp
+void ReqMonitorThread::run() {
+    // Subscribe to event broadcast channel
+    auto eventSubscription = subscribeToEvents();
+
+    while (running) {
+        Event event;
+        if (!eventSubscription.receive(event, 100ms)) continue;
+
+        // Check all subscriptions assigned to this thread
+        for (auto &[connId, sub] : mySubscriptions) {
+            // Only process subscriptions for this thread
+            if (connId % numThreads != threadId) continue;
+
+            // Check if filter matches
+            bool matches = false;
+            for (const auto &filter : sub->filters) {
+                if (filter.matches(event)) {
+                    matches = true;
+                    break;
+                }
+            }
+
+            if (matches) {
+                sendEvent(connId, sub->subId, event);
+            }
+        }
+    }
+}
+```
+
+**Pattern:** Monitor thread watches event stream, sends to matching subscriptions
+
+### CLOSE Handling
+
+```cpp
+void handleCloseMessage(auto *ws, nlohmann::json &&json) {
+    auto *state = ws->getUserData();
+
+    // Parse CLOSE message: ["CLOSE", subId]
+    std::string subId = json[1];
+
+    // Remove subscription
+    activeSubscriptions.erase(state->connId);
+
+    LI << "Subscription closed: connId=" << state->connId
+       << " subId=" << subId;
+}
+```
+
+## Performance Optimizations
+
+### 1. Event Batching
+
+**Problem:** Serializing same event 1000× for 1000 subscribers is wasteful
+
+**Solution:** Serialize once, send to all
+
+```cpp
+// BAD: Serialize for each subscriber
+for (auto &sub : subscriptions) {
+    std::string json = serializeEvent(event);  // Repeated!
+    send(sub.connId, json);
+}
+
+// GOOD: Serialize once
+std::string json = serializeEvent(event);
+for (auto &sub : subscriptions) {
+    send(sub.connId, json);  // Reuse!
+}
+```
+
+**Measurement:** For 1000 subscribers, reduces broadcast time from 100ms to 1ms
+
+### 2. Move Semantics
+
+**Problem:** Copying large JSON objects is expensive
+
+**Solution:** Transfer ownership with `std::move`
+
+```cpp
+// BAD: Copies JSON object
+void dispatch(Message msg) {
+    queue.push(msg);  // Copy
+}
+
+// GOOD: Moves JSON object
+void dispatch(Message &&msg) {
+    queue.push(std::move(msg));  // Move
+}
+```
+
+**Benefit:** Zero-copy message passing between threads
+
+### 3. Pre-allocated Buffers
+
+**Problem:** Allocating buffer for each message
+
+**Solution:** Reuse buffer per connection
+
+```cpp
+struct ConnectionState {
+    std::string parseBuffer;  // Reused for all messages
+};
+
+void handleMessage(std::string_view msg) {
+    state->parseBuffer.assign(msg.data(), msg.size());
+    auto json = nlohmann::json::parse(state->parseBuffer);
+    // ...
+}
+```
+
+**Benefit:** Eliminates 10,000+ allocations/second per connection
+
+### 4. std::variant for Message Types
+
+**Problem:** Virtual function calls for polymorphic messages
+
+**Solution:** `std::variant` with `std::visit`
+
+```cpp
+// BAD: Virtual function (pointer indirection, vtable lookup)
+struct Message {
+    virtual void handle() = 0;
+};
+
+// GOOD: std::variant (no indirection, inlined)
+using Message = std::variant<
+    MsgIngester,
+    MsgReq,
+    MsgWriter,
+    MsgWebSocket
+>;
+
+void handle(Message &&msg) {
+    std::visit([](auto &&m) { m.handle(); }, msg);
+}
+```
+
+**Benefit:** Compiler inlines visit, eliminates virtual call overhead
+
+### 5. Bloom Filter for Duplicate Detection
+
+**Problem:** Database query for every event to check duplicate
+
+**Solution:** In-memory bloom filter for fast negative
+
+```cpp
+class DuplicateDetector {
+    BloomFilter bloom;  // Fast probabilistic check
+
+    bool isDuplicate(const std::string &eventId) {
+        // Fast negative (definitely not seen)
+        if (!bloom.contains(eventId)) {
+            bloom.insert(eventId);
+            return false;
+        }
+
+        // Possible positive (maybe seen, check database)
+        if (db.eventExists(eventId)) {
+            return true;
+        }
+
+        // False positive
+        bloom.insert(eventId);
+        return false;
+    }
+};
+```
+
+**Benefit:** 99% of duplicate checks avoid database query
+
+### 6. Batch Queue Operations
+
+**Problem:** Lock contention on message queue
+
+**Solution:** Batch multiple pushes with single lock
+
+```cpp
+class MessageQueue {
+    std::mutex mutex;
+    std::deque<Message> queue;
+
+    void pushBatch(std::vector<Message> &messages) {
+        std::lock_guard lock(mutex);
+        for (auto &msg : messages) {
+            queue.push_back(std::move(msg));
+        }
+    }
+};
+```
+
+**Benefit:** Reduces lock acquisitions by 10-100×
+
+### 7. ZSTD Dictionary Compression
+
+**Problem:** WebSocket compression slower than desired
+
+**Solution:** Train ZSTD dictionary on typical Nostr messages
+
+```cpp
+// Train dictionary on corpus of Nostr events
+std::string corpus = collectTypicalEvents();
+ZSTD_CDict *dict = ZSTD_createCDict(
+    corpus.data(), corpus.size(),
+    compressionLevel
+);
+
+// Use dictionary for compression
+size_t compressedSize = ZSTD_compress_usingCDict(
+    cctx, dst, dstSize,
+    src, srcSize, dict
+);
+```
+
+**Benefit:** 10-20% better compression ratio, 2× faster decompression
+
+### 8. String Views
+
+**Problem:** Unnecessary string copies when parsing
+
+**Solution:** Use `std::string_view` for zero-copy
+
+```cpp
+// BAD: Copies substring
+std::string extractCommand(const std::string &msg) {
+    return msg.substr(0, 5);  // Copy
+}
+
+// GOOD: View into original string
+std::string_view extractCommand(std::string_view msg) {
+    return msg.substr(0, 5);  // No copy
+}
+```
+
+**Benefit:** Eliminates allocations during parsing
+
+## Compression (permessage-deflate)
+
+### WebSocket Compression Configuration
+
+```cpp
+struct PerMessageDeflate {
+    z_stream deflate_stream;
+    z_stream inflate_stream;
+
+    // Sliding window for compression history
+    static constexpr int WINDOW_BITS = 15;
+    static constexpr int MEM_LEVEL = 8;
+
+    void init() {
+        // Initialize deflate (compression)
+        deflate_stream.zalloc = Z_NULL;
+        deflate_stream.zfree = Z_NULL;
+        deflate_stream.opaque = Z_NULL;
+        deflateInit2(&deflate_stream,
+                     Z_DEFAULT_COMPRESSION,
+                     Z_DEFLATED,
+                     -WINDOW_BITS,  // Negative = no zlib header
+                     MEM_LEVEL,
+                     Z_DEFAULT_STRATEGY);
+
+        // Initialize inflate (decompression)
+        inflate_stream.zalloc = Z_NULL;
+        inflate_stream.zfree = Z_NULL;
+        inflate_stream.opaque = Z_NULL;
+        inflateInit2(&inflate_stream, -WINDOW_BITS);
+    }
+
+    std::string compress(std::string_view data) {
+        // Compress with sliding window
+        deflate_stream.next_in = (Bytef*)data.data();
+        deflate_stream.avail_in = data.size();
+
+        std::string compressed;
+        compressed.resize(deflateBound(&deflate_stream, data.size()));
+
+        deflate_stream.next_out = (Bytef*)compressed.data();
+        deflate_stream.avail_out = compressed.size();
+
+        deflate(&deflate_stream, Z_SYNC_FLUSH);
+
+        compressed.resize(compressed.size() - deflate_stream.avail_out);
+        return compressed;
+    }
+};
+```
+
+**Typical compression ratios:**
+- JSON events: 60-80% reduction
+- Subscription filters: 40-60% reduction
+- Binary events: 10-30% reduction
+
+## Database Schema (LMDB)
+
+strfry uses LMDB (Lightning Memory-Mapped Database) for event storage:
+
+```cpp
+// Key-value stores
+struct EventDB {
+    // Primary event storage (key: event ID, value: event data)
+    lmdb::dbi eventsDB;
+
+    // Index by pubkey (key: pubkey + created_at, value: event ID)
+    lmdb::dbi pubkeyDB;
+
+    // Index by kind (key: kind + created_at, value: event ID)
+    lmdb::dbi kindDB;
+
+    // Index by tags (key: tag_name + tag_value + created_at, value: event ID)
+    lmdb::dbi tagsDB;
+
+    // Deletion index (key: event ID, value: deletion event ID)
+    lmdb::dbi deletionsDB;
+};
+```
+
+**Why LMDB?**
+- Memory-mapped I/O (kernel manages caching)
+- Copy-on-write (MVCC without locks)
+- Ordered keys (enables range queries)
+- Crash-proof (no corruption on power loss)
+
+## Monitoring and Metrics
+
+### Connection Statistics
+
+```cpp
+struct RelayStats {
+    std::atomic<uint64_t> totalConnections{0};
+    std::atomic<uint64_t> activeConnections{0};
+    std::atomic<uint64_t> eventsReceived{0};
+    std::atomic<uint64_t> eventsSent{0};
+    std::atomic<uint64_t> bytesReceived{0};
+    std::atomic<uint64_t> bytesSent{0};
+
+    void recordConnection() {
+        totalConnections.fetch_add(1, std::memory_order_relaxed);
+        activeConnections.fetch_add(1, std::memory_order_relaxed);
+    }
+
+    void recordDisconnection() {
+        activeConnections.fetch_sub(1, std::memory_order_relaxed);
+    }
+
+    void recordEventReceived(size_t bytes) {
+        eventsReceived.fetch_add(1, std::memory_order_relaxed);
+        bytesReceived.fetch_add(bytes, std::memory_order_relaxed);
+    }
+};
+```
+
+**Atomic operations:** Lock-free updates from multiple threads
+
+### Performance Metrics
+
+```cpp
+struct PerformanceMetrics {
+    // Latency histograms
+    Histogram eventIngestionLatency;
+    Histogram subscriptionQueryLatency;
+    Histogram eventBroadcastLatency;
+
+    // Thread pool queue depths
+    std::atomic<size_t> ingesterQueueDepth{0};
+    std::atomic<size_t> writerQueueDepth{0};
+    std::atomic<size_t> reqWorkerQueueDepth{0};
+
+    void recordIngestion(std::chrono::microseconds duration) {
+        eventIngestionLatency.record(duration.count());
+    }
+};
+```
+
+## Configuration
+
+### relay.conf Example
+
+```ini
+[relay]
+bind = 0.0.0.0
+port = 8080
+maxConnections = 10000
+maxMessageSize = 16777216  # 16 MB
+
+[ingester]
+threads = 3
+queueSize = 10000
+
+[writer]
+threads = 1
+queueSize = 1000
+batchSize = 100
+
+[reqWorker]
+threads = 3
+queueSize = 10000
+
+[db]
+path = /var/lib/strfry/events.lmdb
+maxSizeGB = 100
+```
+
+## Deployment Considerations
+
+### System Limits
+
+```bash
+# Increase file descriptor limit
+ulimit -n 65536
+
+# Increase maximum socket connections
+sysctl -w net.core.somaxconn=4096
+
+# TCP tuning
+sysctl -w net.ipv4.tcp_fin_timeout=15
+sysctl -w net.ipv4.tcp_tw_reuse=1
+```
+
+### Memory Requirements
+
+**Per connection:**
+- ConnectionState: ~1 KB
+- WebSocket buffers: ~32 KB (16 KB send + 16 KB receive)
+- Compression state: ~400 KB (200 KB deflate + 200 KB inflate)
+
+**Total:** ~433 KB per connection
+
+**For 10,000 connections:** ~4.3 GB
+
+### CPU Requirements
+
+**Single-core can handle:**
+- 1000 concurrent connections
+- 10,000 events/sec ingestion
+- 100,000 events/sec broadcast (cached)
+
+**Recommended:**
+- 8+ cores for 10,000 connections
+- 16+ cores for 50,000 connections
+
+## Summary
+
+**Key architectural patterns:**
+1. **Single-threaded I/O:** epoll handles all connections in one thread
+2. **Specialized thread pools:** Different operations use dedicated threads
+3. **Deterministic assignment:** Connection ID determines thread assignment
+4. **Move semantics:** Zero-copy message passing
+5. **Event batching:** Serialize once, send to many
+6. **Pre-allocated buffers:** Reuse memory per connection
+7. **Bloom filters:** Fast duplicate detection
+8. **LMDB:** Memory-mapped database for zero-copy reads
+
+**Performance characteristics:**
+- **50,000+ concurrent connections** per server
+- **100,000+ events/sec** throughput
+- **Sub-millisecond** latency for broadcasts
+- **10 GB+ event database** with fast queries
+
+**When to use strfry patterns:**
+- Need maximum performance (trading complexity)
+- Have C++ expertise on team
+- Running large public relay (thousands of users)
+- Want minimal memory footprint
+- Need to scale to 50K+ connections
+
+**Trade-offs:**
+- **Complexity:** More complex than Go/Rust implementations
+- **Portability:** Linux-specific (epoll, LMDB)
+- **Development speed:** Slower iteration than higher-level languages

+# WebSocket Protocol (RFC 6455) - Complete Reference
+
+## Connection Establishment
+
+### HTTP Upgrade Handshake
+
+The WebSocket protocol begins as an HTTP request that upgrades to WebSocket:
+
+**Client Request:**
+```http
+GET /chat HTTP/1.1
+Host: server.example.com
+Upgrade: websocket
+Connection: Upgrade
+Sec-WebSocket-Key: dGhlIHNhbXBsZSBub25jZQ==
+Origin: http://example.com
+Sec-WebSocket-Protocol: chat, superchat
+Sec-WebSocket-Version: 13
+```
+
+**Server Response:**
+```http
+HTTP/1.1 101 Switching Protocols
+Upgrade: websocket
+Connection: Upgrade
+Sec-WebSocket-Accept: s3pPLMBiTxaQ9kYGzzhZRbK+xOo=
+Sec-WebSocket-Protocol: chat
+```
+
+### Handshake Details
+
+**Sec-WebSocket-Key Generation (Client):**
+1. Generate 16 random bytes
+2. Base64-encode the result
+3. Send in `Sec-WebSocket-Key` header
+
+**Sec-WebSocket-Accept Computation (Server):**
+1. Concatenate client key with GUID: `258EAFA5-E914-47DA-95CA-C5AB0DC85B11`
+2. Compute SHA-1 hash of concatenated string
+3. Base64-encode the hash
+4. Send in `Sec-WebSocket-Accept` header
+
+**Example computation:**
+```
+Client Key: dGhlIHNhbXBsZSBub25jZQ==
+Concatenated: dGhlIHNhbXBsZSBub25jZQ==258EAFA5-E914-47DA-95CA-C5AB0DC85B11
+SHA-1 Hash: b37a4f2cc0cb4e7e8cf769a5f3f8f2e8e4c9f7a3
+Base64: s3pPLMBiTxaQ9kYGzzhZRbK+xOo=
+```
+
+**Validation (Client):**
+- Verify HTTP status is 101
+- Verify `Sec-WebSocket-Accept` matches expected value
+- If validation fails, do not establish connection
+
+### Origin Header
+
+The `Origin` header provides protection against cross-site WebSocket hijacking:
+
+**Server-side validation:**
+```go
+func checkOrigin(r *http.Request) bool {
+    origin := r.Header.Get("Origin")
+    allowedOrigins := []string{
+        "https://example.com",
+        "https://app.example.com",
+    }
+    for _, allowed := range allowedOrigins {
+        if origin == allowed {
+            return true
+        }
+    }
+    return false
+}
+```
+
+**Security consideration:** Browser-based clients MUST send Origin header. Non-browser clients MAY omit it. Servers SHOULD validate Origin for browser clients to prevent CSRF attacks.
+
+## Frame Format
+
+### Base Framing Protocol
+
+WebSocket frames use a binary format with variable-length fields:
+
+```
+      0                   1                   2                   3
+      0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1
+     +-+-+-+-+-------+-+-------------+-------------------------------+
+     |F|R|R|R| opcode|M| Payload len |    Extended payload length    |
+     |I|S|S|S|  (4)  |A|     (7)     |             (16/64)           |
+     |N|V|V|V|       |S|             |   (if payload len==126/127)   |
+     | |1|2|3|       |K|             |                               |
+     +-+-+-+-+-------+-+-------------+ - - - - - - - - - - - - - - - +
+     |     Extended payload length continued, if payload len == 127  |
+     + - - - - - - - - - - - - - - - +-------------------------------+
+     |                               |Masking-key, if MASK set to 1  |
+     +-------------------------------+-------------------------------+
+     | Masking-key (continued)       |          Payload Data         |
+     +-------------------------------- - - - - - - - - - - - - - - - +
+     :                     Payload Data continued ...                :
+     + - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - +
+     |                     Payload Data continued ...                |
+     +---------------------------------------------------------------+
+```
+
+### Frame Header Fields
+
+**FIN (1 bit):**
+- `1` = Final fragment in message
+- `0` = More fragments follow
+- Used for message fragmentation
+
+**RSV1, RSV2, RSV3 (1 bit each):**
+- Reserved for extensions
+- MUST be 0 unless extension negotiated
+- Server MUST fail connection if non-zero with no extension
+
+**Opcode (4 bits):**
+- Defines interpretation of payload data
+- See "Frame Opcodes" section below
+
+**MASK (1 bit):**
+- `1` = Payload is masked (required for client-to-server)
+- `0` = Payload is not masked (required for server-to-client)
+- Client MUST mask all frames sent to server
+- Server MUST NOT mask frames sent to client
+
+**Payload Length (7 bits, 7+16 bits, or 7+64 bits):**
+- If 0-125: Actual payload length
+- If 126: Next 2 bytes are 16-bit unsigned payload length
+- If 127: Next 8 bytes are 64-bit unsigned payload length
+
+**Masking-key (0 or 4 bytes):**
+- Present if MASK bit is set
+- 32-bit value used to mask payload
+- MUST be unpredictable (strong entropy source)
+
+### Frame Opcodes
+
+**Data Frame Opcodes:**
+- `0x0` - Continuation Frame
+  - Used for fragmented messages
+  - Must follow initial data frame (text/binary)
+  - Carries same data type as initial frame
+
+- `0x1` - Text Frame
+  - Payload is UTF-8 encoded text
+  - MUST be valid UTF-8
+  - Endpoint MUST fail connection if invalid UTF-8
+
+- `0x2` - Binary Frame
+  - Payload is arbitrary binary data
+  - Application interprets data
+
+- `0x3-0x7` - Reserved for future non-control frames
+
+**Control Frame Opcodes:**
+- `0x8` - Connection Close
+  - Initiates or acknowledges connection closure
+  - MAY contain status code and reason
+  - See "Close Handshake" section
+
+- `0x9` - Ping
+  - Heartbeat mechanism
+  - MAY contain application data
+  - Recipient MUST respond with Pong
+
+- `0xA` - Pong
+  - Response to Ping
+  - MUST contain identical payload as Ping
+  - MAY be sent unsolicited (unidirectional heartbeat)
+
+- `0xB-0xF` - Reserved for future control frames
+
+### Control Frame Constraints
+
+**Control frames are subject to strict rules:**
+
+1. **Maximum payload:** 125 bytes
+   - Allows control frames to fit in single IP packet
+   - Reduces fragmentation
+
+2. **No fragmentation:** Control frames MUST NOT be fragmented
+   - FIN bit MUST be 1
+   - Ensures immediate processing
+
+3. **Interleaving:** Control frames MAY be injected in middle of fragmented message
+   - Enables ping/pong during long transfers
+   - Close frames can interrupt any operation
+
+4. **All control frames MUST be handled immediately**
+
+### Masking
+
+**Purpose of masking:**
+- Prevents cache poisoning attacks
+- Protects against misinterpretation by intermediaries
+- Makes WebSocket traffic unpredictable to proxies
+
+**Masking algorithm:**
+```
+j = i MOD 4
+transformed-octet-i = original-octet-i XOR masking-key-octet-j
+```
+
+**Implementation:**
+```go
+func maskBytes(data []byte, mask [4]byte) {
+    for i := range data {
+        data[i] ^= mask[i%4]
+    }
+}
+```
+
+**Example:**
+```
+Original:     [0x48, 0x65, 0x6C, 0x6C, 0x6F]  // "Hello"
+Masking Key:  [0x37, 0xFA, 0x21, 0x3D]
+Masked:       [0x7F, 0x9F, 0x4D, 0x51, 0x58]
+
+Calculation:
+0x48 XOR 0x37 = 0x7F
+0x65 XOR 0xFA = 0x9F
+0x6C XOR 0x21 = 0x4D
+0x6C XOR 0x3D = 0x51
+0x6F XOR 0x37 = 0x58  (wraps around to mask[0])
+```
+
+**Security requirement:** Masking key MUST be derived from strong source of entropy. Predictable masking keys defeat the security purpose.
+
+## Message Fragmentation
+
+### Why Fragment?
+
+- Send message without knowing total size upfront
+- Multiplex logical channels (interleave messages)
+- Keep control frames responsive during large transfers
+
+### Fragmentation Rules
+
+**Sender rules:**
+1. First fragment has opcode (text/binary)
+2. Subsequent fragments have opcode 0x0 (continuation)
+3. Last fragment has FIN bit set to 1
+4. Control frames MAY be interleaved
+
+**Receiver rules:**
+1. Reassemble fragments in order
+2. Final message type determined by first fragment opcode
+3. Validate UTF-8 across all text fragments
+4. Process control frames immediately (don't wait for FIN)
+
+### Fragmentation Example
+
+**Sending "Hello World" in 3 fragments:**
+
+```
+Frame 1 (Text, More Fragments):
+  FIN=0, Opcode=0x1, Payload="Hello"
+
+Frame 2 (Continuation, More Fragments):
+  FIN=0, Opcode=0x0, Payload=" Wor"
+
+Frame 3 (Continuation, Final):
+  FIN=1, Opcode=0x0, Payload="ld"
+```
+
+**With interleaved Ping:**
+
+```
+Frame 1: FIN=0, Opcode=0x1, Payload="Hello"
+Frame 2: FIN=1, Opcode=0x9, Payload=""        <- Ping (complete)
+Frame 3: FIN=0, Opcode=0x0, Payload=" Wor"
+Frame 4: FIN=1, Opcode=0x0, Payload="ld"
+```
+
+### Implementation Pattern
+
+```go
+type fragmentState struct {
+    messageType int
+    fragments   [][]byte
+}
+
+func (ws *WebSocket) handleFrame(fin bool, opcode int, payload []byte) {
+    switch opcode {
+    case 0x1, 0x2: // Text or Binary (first fragment)
+        if fin {
+            ws.handleCompleteMessage(opcode, payload)
+        } else {
+            ws.fragmentState = &fragmentState{
+                messageType: opcode,
+                fragments:   [][]byte{payload},
+            }
+        }
+
+    case 0x0: // Continuation
+        if ws.fragmentState == nil {
+            ws.fail("Unexpected continuation frame")
+            return
+        }
+        ws.fragmentState.fragments = append(ws.fragmentState.fragments, payload)
+        if fin {
+            complete := bytes.Join(ws.fragmentState.fragments, nil)
+            ws.handleCompleteMessage(ws.fragmentState.messageType, complete)
+            ws.fragmentState = nil
+        }
+
+    case 0x8, 0x9, 0xA: // Control frames
+        ws.handleControlFrame(opcode, payload)
+    }
+}
+```
+
+## Ping and Pong Frames
+
+### Purpose
+
+1. **Keep-alive:** Detect broken connections
+2. **Latency measurement:** Time round-trip
+3. **NAT traversal:** Maintain mapping in stateful firewalls
+
+### Protocol Rules
+
+**Ping (0x9):**
+- MAY be sent by either endpoint at any time
+- MAY contain application data (≤125 bytes)
+- Application data arbitrary (often empty or timestamp)
+
+**Pong (0xA):**
+- MUST be sent in response to Ping
+- MUST contain identical payload as Ping
+- MUST be sent "as soon as practical"
+- MAY be sent unsolicited (one-way heartbeat)
+
+**No Response:**
+- If Pong not received within timeout, connection assumed dead
+- Application should close connection
+
+### Implementation Patterns
+
+**Pattern 1: Automatic Pong (most WebSocket libraries)**
+```go
+// Library handles pong automatically
+ws.SetPingHandler(func(appData string) error {
+    // Custom handler if needed
+    return nil  // Library sends pong automatically
+})
+```
+
+**Pattern 2: Manual Pong**
+```go
+func (ws *WebSocket) handlePing(payload []byte) {
+    pongFrame := Frame{
+        FIN:     true,
+        Opcode:  0xA,
+        Payload: payload,  // Echo same payload
+    }
+    ws.writeFrame(pongFrame)
+}
+```
+
+**Pattern 3: Periodic Client Ping**
+```go
+func (ws *WebSocket) pingLoop() {
+    ticker := time.NewTicker(30 * time.Second)
+    defer ticker.Stop()
+
+    for {
+        select {
+        case <-ticker.C:
+            if err := ws.writePing([]byte{}); err != nil {
+                return  // Connection dead
+            }
+        case <-ws.done:
+            return
+        }
+    }
+}
+```
+
+**Pattern 4: Timeout Detection**
+```go
+const pongWait = 60 * time.Second
+
+ws.SetReadDeadline(time.Now().Add(pongWait))
+ws.SetPongHandler(func(string) error {
+    ws.SetReadDeadline(time.Now().Add(pongWait))
+    return nil
+})
+
+// If no frame received in pongWait, ReadMessage returns timeout error
+```
+
+### Nostr Relay Recommendations
+
+**Server-side:**
+- Send ping every 30-60 seconds
+- Close connection if no pong within 60-120 seconds
+- Log timeout closures for monitoring
+
+**Client-side:**
+- Respond to pings automatically (use library handler)
+- Consider sending unsolicited pongs every 30 seconds (some proxies)
+- Reconnect if no frames received for 120 seconds
+
+## Close Handshake
+
+### Close Frame Structure
+
+**Close frame (Opcode 0x8) payload:**
+```
+     0                   1                   2                   3
+     0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1
+    +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
+    |         Status Code (16)      |  Reason (variable length)...  |
+    +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
+```
+
+**Status Code (2 bytes, optional):**
+- 16-bit unsigned integer
+- Network byte order (big-endian)
+- See "Status Codes" section below
+
+**Reason (variable length, optional):**
+- UTF-8 encoded text
+- MUST be valid UTF-8
+- Typically human-readable explanation
+
+### Close Handshake Sequence
+
+**Initiator (either endpoint):**
+1. Send Close frame with optional status/reason
+2. Stop sending data frames
+3. Continue processing received frames until Close frame received
+4. Close underlying TCP connection
+
+**Recipient:**
+1. Receive Close frame
+2. Send Close frame in response (if not already sent)
+3. Close underlying TCP connection
+
+### Status Codes
+
+**Normal Closure Codes:**
+- `1000` - Normal Closure
+  - Successful operation complete
+  - Default if no code specified
+
+- `1001` - Going Away
+  - Endpoint going away (server shutdown, browser navigation)
+  - Client navigating to new page
+
+**Error Closure Codes:**
+- `1002` - Protocol Error
+  - Endpoint terminating due to protocol error
+  - Invalid frame format, unexpected opcode, etc.
+
+- `1003` - Unsupported Data
+  - Endpoint cannot accept data type
+  - Server received binary when expecting text
+
+- `1007` - Invalid Frame Payload Data
+  - Inconsistent data (e.g., non-UTF-8 in text frame)
+
+- `1008` - Policy Violation
+  - Message violates endpoint policy
+  - Generic code when specific code doesn't fit
+
+- `1009` - Message Too Big
+  - Message too large to process
+
+- `1010` - Mandatory Extension
+  - Client expected server to negotiate extension
+  - Server didn't respond with extension
+
+- `1011` - Internal Server Error
+  - Server encountered unexpected condition
+  - Prevents fulfilling request
+
+**Reserved Codes:**
+- `1004` - Reserved
+- `1005` - No Status Rcvd (internal use only, never sent)
+- `1006` - Abnormal Closure (internal use only, never sent)
+- `1015` - TLS Handshake (internal use only, never sent)
+
+**Custom Application Codes:**
+- `3000-3999` - Library/framework use
+- `4000-4999` - Application use (e.g., Nostr-specific)
+
+### Implementation Patterns
+
+**Graceful close (initiator):**
+```go
+func (ws *WebSocket) Close() error {
+    // Send close frame
+    closeFrame := Frame{
+        FIN:     true,
+        Opcode:  0x8,
+        Payload: encodeCloseStatus(1000, "goodbye"),
+    }
+    ws.writeFrame(closeFrame)
+
+    // Wait for close frame response (with timeout)
+    ws.SetReadDeadline(time.Now().Add(5 * time.Second))
+    for {
+        frame, err := ws.readFrame()
+        if err != nil || frame.Opcode == 0x8 {
+            break
+        }
+        // Process other frames
+    }
+
+    // Close TCP connection
+    return ws.conn.Close()
+}
+```
+
+**Handling received close:**
+```go
+func (ws *WebSocket) handleCloseFrame(payload []byte) {
+    status, reason := decodeClosePayload(payload)
+    log.Printf("Close received: %d %s", status, reason)
+
+    // Send close response
+    closeFrame := Frame{
+        FIN:     true,
+        Opcode:  0x8,
+        Payload: payload,  // Echo same status/reason
+    }
+    ws.writeFrame(closeFrame)
+
+    // Close connection
+    ws.conn.Close()
+}
+```
+
+**Nostr relay close examples:**
+```go
+// Client subscription limit exceeded
+ws.SendClose(4000, "subscription limit exceeded")
+
+// Invalid message format
+ws.SendClose(1002, "protocol error: invalid JSON")
+
+// Relay shutting down
+ws.SendClose(1001, "relay shutting down")
+
+// Client rate limit exceeded
+ws.SendClose(4001, "rate limit exceeded")
+```
+
+## Security Considerations
+
+### Origin-Based Security Model
+
+**Threat:** Malicious web page opens WebSocket to victim server using user's credentials
+
+**Mitigation:**
+1. Server checks `Origin` header
+2. Reject connections from untrusted origins
+3. Implement same-origin or allowlist policy
+
+**Example:**
+```go
+func validateOrigin(r *http.Request) bool {
+    origin := r.Header.Get("Origin")
+
+    // Allow same-origin
+    if origin == "https://"+r.Host {
+        return true
+    }
+
+    // Allowlist trusted origins
+    trusted := []string{
+        "https://app.example.com",
+        "https://mobile.example.com",
+    }
+    for _, t := range trusted {
+        if origin == t {
+            return true
+        }
+    }
+
+    return false
+}
+```
+
+### Masking Attacks
+
+**Why masking is required:**
+- Without masking, attacker can craft WebSocket frames that look like HTTP requests
+- Proxies might misinterpret frame data as HTTP
+- Could lead to cache poisoning or request smuggling
+
+**Example attack (without masking):**
+```
+WebSocket payload: "GET /admin HTTP/1.1\r\nHost: victim.com\r\n\r\n"
+Proxy might interpret as separate HTTP request
+```
+
+**Defense:** Client MUST mask all frames. Server MUST reject unmasked frames from client.
+
+### Connection Limits
+
+**Prevent resource exhaustion:**
+
+```go
+type ConnectionLimiter struct {
+    connections map[string]int
+    maxPerIP    int
+    mu          sync.Mutex
+}
+
+func (cl *ConnectionLimiter) Allow(ip string) bool {
+    cl.mu.Lock()
+    defer cl.mu.Unlock()
+
+    if cl.connections[ip] >= cl.maxPerIP {
+        return false
+    }
+    cl.connections[ip]++
+    return true
+}
+
+func (cl *ConnectionLimiter) Release(ip string) {
+    cl.mu.Lock()
+    defer cl.mu.Unlock()
+    cl.connections[ip]--
+}
+```
+
+### TLS (WSS)
+
+**Use WSS (WebSocket Secure) for:**
+- Authentication credentials
+- Private user data
+- Financial transactions
+- Any sensitive information
+
+**WSS connection flow:**
+1. Establish TLS connection
+2. Perform TLS handshake
+3. Verify server certificate
+4. Perform WebSocket handshake over TLS
+
+**URL schemes:**
+- `ws://` - Unencrypted WebSocket (default port 80)
+- `wss://` - Encrypted WebSocket over TLS (default port 443)
+
+### Message Size Limits
+
+**Prevent memory exhaustion:**
+
+```go
+const maxMessageSize = 512 * 1024  // 512 KB
+
+ws.SetReadLimit(maxMessageSize)
+
+// Or during frame reading:
+if payloadLength > maxMessageSize {
+    ws.SendClose(1009, "message too large")
+    ws.Close()
+}
+```
+
+### Rate Limiting
+
+**Prevent abuse:**
+
+```go
+type RateLimiter struct {
+    limiter *rate.Limiter
+}
+
+func (rl *RateLimiter) Allow() bool {
+    return rl.limiter.Allow()
+}
+
+// Per-connection limiter
+limiter := rate.NewLimiter(10, 20)  // 10 msgs/sec, burst 20
+
+if !limiter.Allow() {
+    ws.SendClose(4001, "rate limit exceeded")
+}
+```
+
+## Error Handling
+
+### Connection Errors
+
+**Types of errors:**
+1. **Network errors:** TCP connection failure, timeout
+2. **Protocol errors:** Invalid frame format, wrong opcode
+3. **Application errors:** Invalid message content
+
+**Handling strategy:**
+```go
+for {
+    frame, err := ws.ReadFrame()
+    if err != nil {
+        // Check error type
+        if netErr, ok := err.(net.Error); ok && netErr.Timeout() {
+            // Timeout - connection likely dead
+            log.Println("Connection timeout")
+            ws.Close()
+            return
+        }
+
+        if err == io.EOF || err == io.ErrUnexpectedEOF {
+            // Connection closed
+            log.Println("Connection closed")
+            return
+        }
+
+        if protocolErr, ok := err.(*ProtocolError); ok {
+            // Protocol violation
+            log.Printf("Protocol error: %v", protocolErr)
+            ws.SendClose(1002, protocolErr.Error())
+            ws.Close()
+            return
+        }
+
+        // Unknown error
+        log.Printf("Unknown error: %v", err)
+        ws.Close()
+        return
+    }
+
+    // Process frame
+}
+```
+
+### UTF-8 Validation
+
+**Text frames MUST contain valid UTF-8:**
+
+```go
+func validateUTF8(data []byte) bool {
+    return utf8.Valid(data)
+}
+
+func handleTextFrame(payload []byte) error {
+    if !validateUTF8(payload) {
+        return fmt.Errorf("invalid UTF-8 in text frame")
+    }
+    // Process valid text
+    return nil
+}
+```
+
+**For fragmented messages:** Validate UTF-8 across all fragments when reassembled.
+
+## Implementation Checklist
+
+### Client Implementation
+
+- [ ] Generate random Sec-WebSocket-Key
+- [ ] Compute and validate Sec-WebSocket-Accept
+- [ ] MUST mask all frames sent to server
+- [ ] Handle unmasked frames from server
+- [ ] Respond to Ping with Pong
+- [ ] Implement close handshake (both initiating and responding)
+- [ ] Validate UTF-8 in text frames
+- [ ] Handle fragmented messages
+- [ ] Set reasonable timeouts
+- [ ] Implement reconnection logic
+
+### Server Implementation
+
+- [ ] Validate Sec-WebSocket-Key format
+- [ ] Compute correct Sec-WebSocket-Accept
+- [ ] Validate Origin header
+- [ ] MUST NOT mask frames sent to client
+- [ ] Reject masked frames from server (protocol error)
+- [ ] Respond to Ping with Pong
+- [ ] Implement close handshake (both initiating and responding)
+- [ ] Validate UTF-8 in text frames
+- [ ] Handle fragmented messages
+- [ ] Implement connection limits (per IP, total)
+- [ ] Implement message size limits
+- [ ] Implement rate limiting
+- [ ] Log connection statistics
+- [ ] Graceful shutdown (close all connections)
+
+### Both Client and Server
+
+- [ ] Handle concurrent read/write safely
+- [ ] Process control frames immediately (even during fragmentation)
+- [ ] Implement proper timeout mechanisms
+- [ ] Log errors with appropriate detail
+- [ ] Handle unexpected close gracefully
+- [ ] Validate frame structure
+- [ ] Check RSV bits (must be 0 unless extension)
+- [ ] Support standard close status codes
+- [ ] Implement proper error handling for all operations
+
+## Common Implementation Mistakes
+
+### 1. Concurrent Writes
+
+**Mistake:** Writing to WebSocket from multiple goroutines without synchronization
+
+**Fix:** Use mutex or single-writer goroutine
+```go
+type WebSocket struct {
+    conn  *websocket.Conn
+    mutex sync.Mutex
+}
+
+func (ws *WebSocket) WriteMessage(data []byte) error {
+    ws.mutex.Lock()
+    defer ws.mutex.Unlock()
+    return ws.conn.WriteMessage(websocket.TextMessage, data)
+}
+```
+
+### 2. Not Handling Pong
+
+**Mistake:** Sending Ping but not updating read deadline on Pong
+
+**Fix:**
+```go
+ws.SetPongHandler(func(string) error {
+    ws.SetReadDeadline(time.Now().Add(pongWait))
+    return nil
+})
+```
+
+### 3. Forgetting Close Handshake
+
+**Mistake:** Just calling `conn.Close()` without sending Close frame
+
+**Fix:** Send Close frame first, wait for response, then close TCP
+
+### 4. Not Validating UTF-8
+
+**Mistake:** Accepting any bytes in text frames
+
+**Fix:** Validate UTF-8 and fail connection on invalid text
+
+### 5. No Message Size Limit
+
+**Mistake:** Allowing unlimited message sizes
+
+**Fix:** Set `SetReadLimit()` to reasonable value (e.g., 512 KB)
+
+### 6. Blocking on Write
+
+**Mistake:** Blocking indefinitely on slow clients
+
+**Fix:** Set write deadline before each write
+```go
+ws.SetWriteDeadline(time.Now().Add(10 * time.Second))
+```
+
+### 7. Memory Leaks
+
+**Mistake:** Not cleaning up resources on disconnect
+
+**Fix:** Use defer for cleanup, ensure all goroutines terminate
+
+### 8. Race Conditions in Close
+
+**Mistake:** Multiple goroutines trying to close connection
+
+**Fix:** Use `sync.Once` for close operation
+```go
+type WebSocket struct {
+    conn      *websocket.Conn
+    closeOnce sync.Once
+}
+
+func (ws *WebSocket) Close() error {
+    var err error
+    ws.closeOnce.Do(func() {
+        err = ws.conn.Close()
+    })
+    return err
+}
+```

+# React Practical Examples
+
+This file contains real-world examples of React patterns and solutions.
+
+## Example 1: Custom Hook for Data Fetching
+
+```typescript
+import { useState, useEffect } from 'react'
+
+interface FetchState<T> {
+  data: T | null
+  loading: boolean
+  error: Error | null
+}
+
+const useFetch = <T,>(url: string) => {
+  const [state, setState] = useState<FetchState<T>>({
+    data: null,
+    loading: true,
+    error: null
+  })
+  
+  useEffect(() => {
+    let cancelled = false
+    const controller = new AbortController()
+    
+    const fetchData = async () => {
+      try {
+        setState(prev => ({ ...prev, loading: true, error: null }))
+        
+        const response = await fetch(url, { 
+          signal: controller.signal 
+        })
+        
+        if (!response.ok) {
+          throw new Error(`HTTP error! status: ${response.status}`)
+        }

+
+## Example 2: Form with Validation
+
+```typescript
+import { useState, useCallback } from 'react'
+import { z } from 'zod'
+
+const userSchema = z.object({
+  name: z.string().min(2, 'Name must be at least 2 characters'),

+        {isSubmitting ? 'Submitting...' : 'Submit'}
+      </button>
+    </form>
+  )
+}
+```

+## Example 3: Modal with Portal
+
+```typescript
+import { createPortal } from 'react-dom'
+import { useEffect, useRef, useState } from 'react'
+
+interface ModalProps {
+  isOpen: boolean
+  onClose: () => void
+  children: React.ReactNode
+  title?: string
+}
+
+const Modal = ({ isOpen, onClose, children, title }: ModalProps) => {
+  const modalRef = useRef<HTMLDivElement>(null)
+  
+  // Close on Escape key
+  useEffect(() => {

+    }
+

+# React Hooks Quick Reference
+
+## State Hooks
+
+### useState
+```typescript
+const [state, setState] = useState<Type>(initialValue)
+const [count, setCount] = useState(0)
+
+// Functional update
+setCount(prev => prev + 1)
+
+// Lazy initialization
+const [state, setState] = useState(() => expensiveComputation())
+```
+
+### useReducer
+```typescript
+type State = { count: number }
+type Action = { type: 'increment' } | { type: 'decrement' }
+
+const reducer = (state: State, action: Action): State => {
+  switch (action.type) {
+    case 'increment': return { count: state.count + 1 }
+    case 'decrement': return { count: state.count - 1 }
+  }
+}
+
+const [state, dispatch] = useReducer(reducer, { count: 0 })
+dispatch({ type: 'increment' })
+```
+
+### useActionState (React 19)
+```typescript
+const [state, formAction, isPending] = useActionState(
+  async (previousState, formData: FormData) => {
+    // Server action
+    return await processForm(formData)
+  },
+  initialState
+)
+
+<form action={formAction}>
+  <button disabled={isPending}>Submit</button>
+</form>
+```
+
+## Effect Hooks
+
+### useEffect
+```typescript
+useEffect(() => {
+  // Side effect
+  const subscription = api.subscribe()
+  
+  // Cleanup
+  return () => subscription.unsubscribe()
+}, [dependencies])
+```
+
+**Timing**: After render & paint
+**Use for**: Data fetching, subscriptions, DOM mutations
+
+### useLayoutEffect
+```typescript
+useLayoutEffect(() => {
+  // Runs before paint
+  const height = ref.current.offsetHeight
+  setHeight(height)
+}, [])
+```
+
+**Timing**: After render, before paint
+**Use for**: DOM measurements, preventing flicker
+
+### useInsertionEffect
+```typescript
+useInsertionEffect(() => {
+  // Insert styles before any DOM reads
+  const style = document.createElement('style')
+  style.textContent = css
+  document.head.appendChild(style)
+  return () => document.head.removeChild(style)
+}, [css])
+```
+
+**Timing**: Before any DOM mutations
+**Use for**: CSS-in-JS libraries
+
+## Performance Hooks
+
+### useMemo
+```typescript
+const memoizedValue = useMemo(() => {
+  return expensiveComputation(a, b)
+}, [a, b])
+```
+
+**Use for**: Expensive calculations, stable object references
+
+### useCallback
+```typescript
+const memoizedCallback = useCallback(() => {
+  doSomething(a, b)
+}, [a, b])
+```
+
+**Use for**: Passing callbacks to optimized components
+
+## Ref Hooks
+
+### useRef
+```typescript
+// DOM reference
+const ref = useRef<HTMLDivElement>(null)
+ref.current?.focus()
+
+// Mutable value (doesn't trigger re-render)
+const countRef = useRef(0)
+countRef.current += 1
+```
+
+### useImperativeHandle
+```typescript
+useImperativeHandle(ref, () => ({
+  focus: () => inputRef.current?.focus(),
+  clear: () => inputRef.current && (inputRef.current.value = '')
+}), [])
+```
+
+## Context Hook
+
+### useContext
+```typescript
+const value = useContext(MyContext)
+```
+
+Must be used within a Provider.
+
+## Transition Hooks
+
+### useTransition
+```typescript
+const [isPending, startTransition] = useTransition()
+
+startTransition(() => {
+  setState(newValue)  // Non-urgent update
+})
+```
+
+### useDeferredValue
+```typescript
+const [input, setInput] = useState('')
+const deferredInput = useDeferredValue(input)
+
+// Use deferredInput for expensive operations
+const results = useMemo(() => search(deferredInput), [deferredInput])
+```
+
+## Optimistic Updates (React 19)
+
+### useOptimistic
+```typescript
+const [optimisticState, addOptimistic] = useOptimistic(
+  actualState,
+  (currentState, optimisticValue) => {
+    return [...currentState, optimisticValue]
+  }
+)
+```
+
+## Other Hooks
+
+### useId
+```typescript
+const id = useId()
+<label htmlFor={id}>Name</label>
+<input id={id} />
+```
+
+### useSyncExternalStore
+```typescript
+const state = useSyncExternalStore(
+  subscribe,
+  getSnapshot,
+  getServerSnapshot
+)
+```
+
+### useDebugValue
+```typescript
+useDebugValue(isOnline ? 'Online' : 'Offline')
+```
+
+### use (React 19)
+```typescript
+// Read context or promise
+const value = use(MyContext)
+const data = use(fetchPromise)  // Must be in Suspense
+```
+
+## Form Hooks (React DOM)
+
+### useFormStatus
+```typescript
+import { useFormStatus } from 'react-dom'
+
+const { pending, data, method, action } = useFormStatus()
+```
+
+## Hook Rules
+
+1. **Only call at top level** - Not in loops, conditions, or nested functions
+2. **Only call from React functions** - Components or custom hooks
+3. **Custom hooks start with "use"** - Naming convention
+4. **Same hooks in same order** - Every render must call same hooks
+
+## Dependencies Best Practices
+
+1. **Include all used values** - Variables, props, state from component scope
+2. **Use ESLint plugin** - `eslint-plugin-react-hooks` enforces rules
+3. **Functions as dependencies** - Wrap with useCallback or define outside component
+4. **Object/array dependencies** - Use useMemo for stable references
+
+## Common Patterns
+
+### Fetching Data
+```typescript
+const [data, setData] = useState(null)
+const [loading, setLoading] = useState(true)
+const [error, setError] = useState(null)
+
+useEffect(() => {
+  const controller = new AbortController()
+  
+  fetch('/api/data', { signal: controller.signal })
+    .then(res => res.json())
+    .then(setData)
+    .catch(setError)
+    .finally(() => setLoading(false))
+  
+  return () => controller.abort()
+}, [])
+```
+
+### Debouncing
+```typescript
+const [value, setValue] = useState('')
+const [debouncedValue, setDebouncedValue] = useState(value)
+
+useEffect(() => {
+  const timer = setTimeout(() => {
+    setDebouncedValue(value)
+  }, 500)
+  
+  return () => clearTimeout(timer)
+}, [value])
+```
+
+### Previous Value
+```typescript
+const usePrevious = <T,>(value: T): T | undefined => {
+  const ref = useRef<T>()
+  useEffect(() => {
+    ref.current = value
+  })
+  return ref.current
+}
+```
+
+### Interval
+```typescript
+useEffect(() => {
+  const id = setInterval(() => {
+    setCount(c => c + 1)
+  }, 1000)
+  
+  return () => clearInterval(id)
+}, [])
+```
+
+### Event Listeners
+```typescript
+useEffect(() => {
+  const handleResize = () => setWidth(window.innerWidth)
+  
+  window.addEventListener('resize', handleResize)
+  return () => window.removeEventListener('resize', handleResize)
+}, [])
+```

+# React Performance Optimization Guide
+
+## Overview
+
+This guide covers performance optimization strategies for React 19 applications.
+
+## Measurement & Profiling
+
+### React DevTools Profiler
+
+Record performance data:
+1. Open React DevTools
+2. Go to Profiler tab
+3. Click record button
+4. Interact with app
+5. Stop recording
+6. Analyze flame graph and ranked chart
+
+### Profiler Component
+
+```typescript
+import { Profiler } from 'react'
+
+const App = () => {
+  const onRender = (
+    id: string,
+    phase: 'mount' | 'update',
+    actualDuration: number,
+    baseDuration: number,
+    startTime: number,
+    commitTime: number
+  ) => {
+    console.log({
+      component: id,
+      phase,
+      actualDuration,  // Time spent rendering this update
+      baseDuration     // Estimated time without memoization
+    })
+  }
+  
+  return (
+    <Profiler id="App" onRender={onRender}>
+      <YourApp />
+    </Profiler>
+  )
+}
+```
+
+### Performance Metrics
+
+```typescript
+// Custom performance tracking
+const startTime = performance.now()
+// ... do work
+const endTime = performance.now()
+console.log(`Operation took ${endTime - startTime}ms`)
+
+// React rendering metrics
+import { unstable_trace as trace } from 'react'
+
+trace('expensive-operation', async () => {
+  await performExpensiveOperation()
+})
+```
+
+## Memoization Strategies
+
+### React.memo
+
+Prevent unnecessary re-renders:
+
+```typescript
+// Basic memoization
+const ExpensiveComponent = memo(({ data }: Props) => {
+  return <div>{processData(data)}</div>
+})
+
+// Custom comparison
+const MemoizedComponent = memo(
+  ({ user }: Props) => <UserCard user={user} />,
+  (prevProps, nextProps) => {
+    // Return true if props are equal (skip render)
+    return prevProps.user.id === nextProps.user.id
+  }
+)
+```
+
+**When to use:**
+- Component renders often with same props
+- Rendering is expensive
+- Component receives complex prop objects
+
+**When NOT to use:**
+- Props change frequently
+- Component is already fast
+- Premature optimization
+
+### useMemo
+
+Memoize computed values:
+
+```typescript
+const SortedList = ({ items, filter }: Props) => {
+  // Without memoization - runs every render
+  const filteredItems = items.filter(item => item.type === filter)
+  const sortedItems = filteredItems.sort((a, b) => a.name.localeCompare(b.name))
+  
+  // With memoization - only runs when dependencies change
+  const sortedFilteredItems = useMemo(() => {
+    const filtered = items.filter(item => item.type === filter)
+    return filtered.sort((a, b) => a.name.localeCompare(b.name))
+  }, [items, filter])
+  
+  return (
+    <ul>
+      {sortedFilteredItems.map(item => (
+        <li key={item.id}>{item.name}</li>
+      ))}
+    </ul>
+  )
+}
+```
+
+**When to use:**
+- Expensive calculations (sorting, filtering large arrays)
+- Creating stable object references
+- Computed values used as dependencies
+
+### useCallback
+
+Memoize callback functions:
+
+```typescript
+const Parent = () => {
+  const [count, setCount] = useState(0)
+  
+  // Without useCallback - new function every render
+  const handleClick = () => {
+    setCount(c => c + 1)
+  }
+  
+  // With useCallback - stable function reference
+  const handleClickMemo = useCallback(() => {
+    setCount(c => c + 1)
+  }, [])
+  
+  return <MemoizedChild onClick={handleClickMemo} />
+}
+
+const MemoizedChild = memo(({ onClick }: Props) => {
+  return <button onClick={onClick}>Click</button>
+})
+```
+
+**When to use:**
+- Passing callbacks to memoized components
+- Callback is used in dependency array
+- Callback is expensive to create
+
+## React Compiler (Automatic Optimization)
+
+### Enable React Compiler
+
+React 19 can automatically optimize without manual memoization:
+
+```javascript
+// babel.config.js
+module.exports = {
+  plugins: [
+    ['react-compiler', {
+      compilationMode: 'all',  // Optimize all components
+    }]
+  ]
+}
+```
+
+### Compilation Modes
+
+```javascript
+{
+  compilationMode: 'annotation',  // Only components with "use memo"
+  compilationMode: 'all',         // All components (recommended)
+  compilationMode: 'infer'        // Based on component complexity
+}
+```
+
+### Directives
+
+```typescript
+// Force memoization
+'use memo'
+const Component = ({ data }: Props) => {
+  return <div>{data}</div>
+}
+
+// Prevent memoization
+'use no memo'
+const SimpleComponent = ({ text }: Props) => {
+  return <span>{text}</span>
+}
+```
+
+## State Management Optimization
+
+### State Colocation
+
+Keep state as close as possible to where it's used:
+
+```typescript
+// Bad - state too high
+const App = () => {
+  const [showModal, setShowModal] = useState(false)
+  
+  return (
+    <>
+      <Header />
+      <Content />
+      <Modal show={showModal} onClose={() => setShowModal(false)} />
+    </>
+  )
+}
+
+// Good - state colocated
+const App = () => {
+  return (
+    <>
+      <Header />
+      <Content />
+      <ModalContainer />
+    </>
+  )
+}
+
+const ModalContainer = () => {
+  const [showModal, setShowModal] = useState(false)
+  
+  return <Modal show={showModal} onClose={() => setShowModal(false)} />
+}
+```
+
+### Split Context
+
+Avoid unnecessary re-renders by splitting context:
+
+```typescript
+// Bad - single context causes all consumers to re-render
+const AppContext = createContext({ user, theme, settings })
+
+// Good - split into separate contexts
+const UserContext = createContext(user)
+const ThemeContext = createContext(theme)
+const SettingsContext = createContext(settings)
+```
+
+### Context with useMemo
+
+```typescript
+const ThemeProvider = ({ children }: Props) => {
+  const [theme, setTheme] = useState('light')
+  
+  // Memoize context value to prevent unnecessary re-renders
+  const value = useMemo(() => ({
+    theme,
+    setTheme
+  }), [theme])
+  
+  return (
+    <ThemeContext.Provider value={value}>
+      {children}
+    </ThemeContext.Provider>
+  )
+}
+```
+
+## Code Splitting & Lazy Loading
+
+### React.lazy
+
+Split components into separate bundles:
+
+```typescript
+import { lazy, Suspense } from 'react'
+
+// Lazy load components
+const Dashboard = lazy(() => import('./Dashboard'))
+const Settings = lazy(() => import('./Settings'))
+const Profile = lazy(() => import('./Profile'))
+
+const App = () => {
+  return (
+    <Suspense fallback={<Loading />}>
+      <Routes>
+        <Route path="/dashboard" element={<Dashboard />} />
+        <Route path="/settings" element={<Settings />} />
+        <Route path="/profile" element={<Profile />} />
+      </Routes>
+    </Suspense>
+  )
+}
+```
+
+### Route-based Splitting
+
+```typescript
+// App.tsx
+const routes = [
+  { path: '/', component: lazy(() => import('./pages/Home')) },
+  { path: '/about', component: lazy(() => import('./pages/About')) },
+  { path: '/products', component: lazy(() => import('./pages/Products')) },
+]
+
+const App = () => (
+  <Suspense fallback={<PageLoader />}>
+    <Routes>
+      {routes.map(({ path, component: Component }) => (
+        <Route key={path} path={path} element={<Component />} />
+      ))}
+    </Routes>
+  </Suspense>
+)
+```
+
+### Component-based Splitting
+
+```typescript
+// Split expensive components
+const HeavyChart = lazy(() => import('./HeavyChart'))
+
+const Dashboard = () => {
+  const [showChart, setShowChart] = useState(false)
+  
+  return (
+    <>
+      <button onClick={() => setShowChart(true)}>
+        Load Chart
+      </button>
+      {showChart && (
+        <Suspense fallback={<ChartSkeleton />}>
+          <HeavyChart />
+        </Suspense>
+      )}
+    </>
+  )
+}
+```
+
+## List Rendering Optimization
+
+### Keys
+
+Always use stable, unique keys:
+
+```typescript
+// Bad - index as key (causes issues on reorder/insert)
+{items.map((item, index) => (
+  <Item key={index} data={item} />
+))}
+
+// Good - unique ID as key
+{items.map(item => (
+  <Item key={item.id} data={item} />
+))}
+
+// For static lists without IDs
+{items.map(item => (
+  <Item key={`${item.name}-${item.category}`} data={item} />
+))}
+```
+
+### Virtualization
+
+For long lists, render only visible items:
+
+```typescript
+import { useVirtualizer } from '@tanstack/react-virtual'
+
+const VirtualList = ({ items }: { items: Item[] }) => {
+  const parentRef = useRef<HTMLDivElement>(null)
+  
+  const virtualizer = useVirtualizer({
+    count: items.length,
+    getScrollElement: () => parentRef.current,
+    estimateSize: () => 50,  // Estimated item height
+    overscan: 5  // Render 5 extra items above/below viewport
+  })
+  
+  return (
+    <div ref={parentRef} style={{ height: '400px', overflow: 'auto' }}>
+      <div
+        style={{
+          height: `${virtualizer.getTotalSize()}px`,
+          position: 'relative'
+        }}
+      >
+        {virtualizer.getVirtualItems().map(virtualItem => (
+          <div
+            key={virtualItem.key}
+            style={{
+              position: 'absolute',
+              top: 0,
+              left: 0,
+              width: '100%',
+              height: `${virtualItem.size}px`,
+              transform: `translateY(${virtualItem.start}px)`
+            }}
+          >
+            <Item data={items[virtualItem.index]} />
+          </div>
+        ))}
+      </div>
+    </div>
+  )
+}
+```
+
+### Pagination
+
+```typescript
+const PaginatedList = ({ items }: Props) => {
+  const [page, setPage] = useState(1)
+  const itemsPerPage = 20
+  
+  const paginatedItems = useMemo(() => {
+    const start = (page - 1) * itemsPerPage
+    const end = start + itemsPerPage
+    return items.slice(start, end)
+  }, [items, page, itemsPerPage])
+  
+  return (
+    <>
+      {paginatedItems.map(item => (
+        <Item key={item.id} data={item} />
+      ))}
+      <Pagination 
+        page={page} 
+        total={Math.ceil(items.length / itemsPerPage)}
+        onChange={setPage}
+      />
+    </>
+  )
+}
+```
+
+## Transitions & Concurrent Features
+
+### useTransition
+
+Keep UI responsive during expensive updates:
+
+```typescript
+const SearchPage = () => {
+  const [query, setQuery] = useState('')
+  const [results, setResults] = useState([])
+  const [isPending, startTransition] = useTransition()
+  
+  const handleSearch = (value: string) => {
+    setQuery(value)  // Urgent - update input immediately
+    
+    // Non-urgent - can be interrupted
+    startTransition(() => {
+      const filtered = expensiveFilter(items, value)
+      setResults(filtered)
+    })
+  }
+  
+  return (
+    <>
+      <input value={query} onChange={e => handleSearch(e.target.value)} />
+      {isPending && <Spinner />}
+      <ResultsList results={results} />
+    </>
+  )
+}
+```
+
+### useDeferredValue
+
+Defer non-urgent renders:
+
+```typescript
+const SearchPage = () => {
+  const [query, setQuery] = useState('')
+  const deferredQuery = useDeferredValue(query)
+  
+  // Input updates immediately
+  // Results update with deferred value (can be interrupted)
+  const results = useMemo(() => {
+    return expensiveFilter(items, deferredQuery)
+  }, [deferredQuery])
+  
+  return (
+    <>
+      <input value={query} onChange={e => setQuery(e.target.value)} />
+      <ResultsList results={results} />
+    </>
+  )
+}
+```
+
+## Image & Asset Optimization
+
+### Lazy Load Images
+
+```typescript
+const LazyImage = ({ src, alt }: Props) => {
+  const [isLoaded, setIsLoaded] = useState(false)
+  
+  return (
+    <div className="relative">
+      {!isLoaded && <ImageSkeleton />}
+      <img
+        src={src}
+        alt={alt}
+        loading="lazy"  // Native lazy loading
+        onLoad={() => setIsLoaded(true)}
+        className={isLoaded ? 'opacity-100' : 'opacity-0'}
+      />
+    </div>
+  )
+}
+```
+
+### Next.js Image Component
+
+```typescript
+import Image from 'next/image'
+
+const OptimizedImage = () => (
+  <Image
+    src="/hero.jpg"
+    alt="Hero"
+    width={800}
+    height={600}
+    priority  // Load immediately for above-fold images
+    placeholder="blur"
+    blurDataURL="data:image/jpeg;base64,..."
+  />
+)
+```
+
+## Bundle Size Optimization
+
+### Tree Shaking
+
+Import only what you need:
+
+```typescript
+// Bad - imports entire library
+import _ from 'lodash'
+
+// Good - import only needed functions
+import debounce from 'lodash/debounce'
+import throttle from 'lodash/throttle'
+
+// Even better - use native methods when possible
+const debounce = (fn, delay) => {
+  let timeoutId
+  return (...args) => {
+    clearTimeout(timeoutId)
+    timeoutId = setTimeout(() => fn(...args), delay)
+  }
+}
+```
+
+### Analyze Bundle
+
+```bash
+# Next.js
+ANALYZE=true npm run build
+
+# Create React App
+npm install --save-dev webpack-bundle-analyzer
+```
+
+### Dynamic Imports
+
+```typescript
+// Load library only when needed
+const handleExport = async () => {
+  const { jsPDF } = await import('jspdf')
+  const doc = new jsPDF()
+  doc.save('report.pdf')
+}
+```
+
+## Common Performance Pitfalls
+
+### 1. Inline Object Creation
+
+```typescript
+// Bad - new object every render
+<Component style={{ margin: 10 }} />
+
+// Good - stable reference
+const style = { margin: 10 }
+<Component style={style} />
+
+// Or use useMemo
+const style = useMemo(() => ({ margin: 10 }), [])
+```
+
+### 2. Inline Functions
+
+```typescript
+// Bad - new function every render (if child is memoized)
+<MemoizedChild onClick={() => handleClick(id)} />
+
+// Good
+const handleClickMemo = useCallback(() => handleClick(id), [id])
+<MemoizedChild onClick={handleClickMemo} />
+```
+
+### 3. Spreading Props
+
+```typescript
+// Bad - causes re-renders even when props unchanged
+<Component {...props} />
+
+// Good - pass only needed props
+<Component value={props.value} onChange={props.onChange} />
+```
+
+### 4. Large Context
+
+```typescript
+// Bad - everything re-renders on any state change
+const AppContext = createContext({ user, theme, cart, settings, ... })
+
+// Good - split into focused contexts
+const UserContext = createContext(user)
+const ThemeContext = createContext(theme)
+const CartContext = createContext(cart)
+```
+

+# React Server Components & Server Functions
+
+## Overview
+
+React Server Components (RSC) allow components to render on the server, improving performance and enabling direct data access. Server Functions allow client components to call server-side functions.
+
+## Server Components
+
+### What are Server Components?
+
+Components that run **only on the server**:
+- Can access databases directly
+- Zero bundle size (code stays on server)
+- Better performance (less JavaScript to client)
+- Automatic code splitting
+
+### Creating Server Components
+
+```typescript
+// app/products/page.tsx
+// Server Component by default in App Router
+
+import { db } from '@/lib/db'
+
+const ProductsPage = async () => {
+  // Direct database access
+  const products = await db.product.findMany({
+    where: { active: true },
+    include: { category: true }
+  })
+  
+  return (
+    <div>
+      <h1>Products</h1>
+      {products.map(product => (
+        <ProductCard key={product.id} product={product} />
+      ))}
+    </div>
+  )
+}
+
+export default ProductsPage
+```
+
+### Server Component Rules
+
+**Can do:**
+- Access databases and APIs directly
+- Use server-only modules (fs, path, etc.)
+- Keep secrets secure (API keys, tokens)
+- Reduce client bundle size
+- Use async/await at top level
+
+**Cannot do:**
+- Use hooks (useState, useEffect, etc.)
+- Use browser APIs (window, document)
+- Attach event handlers (onClick, etc.)
+- Use Context
+
+### Mixing Server and Client Components
+
+```typescript
+// Server Component (default)
+const Page = async () => {
+  const data = await fetchData()
+  
+  return (
+    <div>
+      <ServerComponent data={data} />
+      {/* Client component for interactivity */}
+      <ClientComponent initialData={data} />
+    </div>
+  )
+}
+
+// Client Component
+'use client'
+
+import { useState } from 'react'
+
+const ClientComponent = ({ initialData }) => {
+  const [count, setCount] = useState(0)
+  
+  return (
+    <button onClick={() => setCount(c => c + 1)}>
+      {count}
+    </button>
+  )
+}
+```
+
+### Server Component Patterns
+
+#### Data Fetching
+```typescript
+// app/user/[id]/page.tsx
+interface PageProps {
+  params: { id: string }
+}
+
+const UserPage = async ({ params }: PageProps) => {
+  const user = await db.user.findUnique({
+    where: { id: params.id }
+  })
+  
+  if (!user) {
+    notFound()  // Next.js 404
+  }
+  
+  return <UserProfile user={user} />
+}
+```
+
+#### Parallel Data Fetching
+```typescript
+const DashboardPage = async () => {
+  // Fetch in parallel
+  const [user, orders, stats] = await Promise.all([
+    fetchUser(),
+    fetchOrders(),
+    fetchStats()
+  ])
+  
+  return (
+    <>
+      <UserHeader user={user} />
+      <OrdersList orders={orders} />
+      <StatsWidget stats={stats} />
+    </>
+  )
+}
+```
+
+#### Streaming with Suspense
+```typescript
+const Page = () => {
+  return (
+    <>
+      <Header />
+      <Suspense fallback={<ProductsSkeleton />}>
+        <Products />
+      </Suspense>
+      <Suspense fallback={<ReviewsSkeleton />}>
+        <Reviews />
+      </Suspense>
+    </>
+  )
+}
+
+const Products = async () => {
+  const products = await fetchProducts()  // Slow query
+  return <ProductsList products={products} />
+}
+```
+
+## Server Functions (Server Actions)
+
+### What are Server Functions?
+
+Functions that run on the server but can be called from client components:
+- Marked with `'use server'` directive
+- Can mutate data
+- Integrated with forms
+- Type-safe with TypeScript
+
+### Creating Server Functions
+
+#### File-level directive
+```typescript
+// app/actions.ts
+'use server'
+
+import { db } from '@/lib/db'
+import { revalidatePath } from 'next/cache'
+
+export async function createProduct(formData: FormData) {
+  const name = formData.get('name') as string
+  const price = Number(formData.get('price'))
+  
+  const product = await db.product.create({
+    data: { name, price }
+  })
+  
+  revalidatePath('/products')
+  return product
+}
+
+export async function deleteProduct(id: string) {
+  await db.product.delete({ where: { id } })
+  revalidatePath('/products')
+}
+```
+
+#### Function-level directive
+```typescript
+// Inside a Server Component
+const MyComponent = async () => {
+  async function handleSubmit(formData: FormData) {
+    'use server'
+    const email = formData.get('email') as string
+    await saveEmail(email)
+  }
+  
+  return <form action={handleSubmit}>...</form>
+}
+```
+
+### Using Server Functions
+
+#### With Forms
+```typescript
+'use client'
+
+import { createProduct } from './actions'
+
+const ProductForm = () => {
+  return (
+    <form action={createProduct}>
+      <input name="name" required />
+      <input name="price" type="number" required />
+      <button type="submit">Create</button>
+    </form>
+  )
+}
+```
+
+#### With useActionState
+```typescript
+'use client'
+
+import { useActionState } from 'react'
+import { createProduct } from './actions'
+
+type FormState = {
+  message: string
+  success: boolean
+} | null
+
+const ProductForm = () => {
+  const [state, formAction, isPending] = useActionState<FormState>(
+    async (previousState, formData: FormData) => {
+      try {
+        await createProduct(formData)
+        return { message: 'Product created!', success: true }
+      } catch (error) {
+        return { message: 'Failed to create product', success: false }
+      }
+    },
+    null
+  )
+  
+  return (
+    <form action={formAction}>
+      <input name="name" required />
+      <input name="price" type="number" required />
+      <button disabled={isPending}>
+        {isPending ? 'Creating...' : 'Create'}
+      </button>
+      {state?.message && (
+        <p className={state.success ? 'text-green-600' : 'text-red-600'}>
+          {state.message}
+        </p>
+      )}
+    </form>
+  )
+}
+```
+
+#### Programmatic Invocation
+```typescript
+'use client'
+
+import { deleteProduct } from './actions'
+
+const DeleteButton = ({ productId }: { productId: string }) => {
+  const [isPending, setIsPending] = useState(false)
+  
+  const handleDelete = async () => {
+    setIsPending(true)
+    try {
+      await deleteProduct(productId)
+    } catch (error) {
+      console.error(error)
+    } finally {
+      setIsPending(false)
+    }
+  }
+  
+  return (
+    <button onClick={handleDelete} disabled={isPending}>
+      {isPending ? 'Deleting...' : 'Delete'}
+    </button>
+  )
+}
+```
+
+### Server Function Patterns
+
+#### Validation with Zod
+```typescript
+'use server'
+
+import { z } from 'zod'
+
+const ProductSchema = z.object({
+  name: z.string().min(3),
+  price: z.number().positive(),
+  description: z.string().optional()
+})
+
+export async function createProduct(formData: FormData) {
+  const rawData = {
+    name: formData.get('name'),
+    price: Number(formData.get('price')),
+    description: formData.get('description')
+  }
+  
+  // Validate
+  const result = ProductSchema.safeParse(rawData)
+  if (!result.success) {
+    return { 
+      success: false, 
+      errors: result.error.flatten().fieldErrors 
+    }
+  }
+  
+  // Create product
+  const product = await db.product.create({
+    data: result.data
+  })
+  
+  revalidatePath('/products')
+  return { success: true, product }
+}
+```
+
+#### Authentication Check
+```typescript
+'use server'
+
+import { auth } from '@/lib/auth'
+import { redirect } from 'next/navigation'
+
+export async function createOrder(formData: FormData) {
+  const session = await auth()
+  
+  if (!session?.user) {
+    redirect('/login')
+  }
+  
+  const order = await db.order.create({
+    data: {
+      userId: session.user.id,
+      // ... other fields
+    }
+  })
+  
+  return order
+}
+```
+
+#### Error Handling
+```typescript
+'use server'
+
+export async function updateProfile(formData: FormData) {
+  try {
+    const userId = await getCurrentUserId()
+    
+    const profile = await db.user.update({
+      where: { id: userId },
+      data: {
+        name: formData.get('name') as string,
+        bio: formData.get('bio') as string
+      }
+    })
+    
+    revalidatePath('/profile')
+    return { success: true, profile }
+  } catch (error) {
+    console.error('Failed to update profile:', error)
+    return { 
+      success: false, 
+      error: 'Failed to update profile. Please try again.' 
+    }
+  }
+}
+```
+
+#### Optimistic Updates
+```typescript
+'use client'
+
+import { useOptimistic } from 'react'
+import { likePost } from './actions'
+
+const Post = ({ post }: { post: Post }) => {
+  const [optimisticLikes, addOptimisticLike] = useOptimistic(
+    post.likes,
+    (currentLikes) => currentLikes + 1
+  )
+  
+  const handleLike = async () => {
+    addOptimisticLike(null)
+    await likePost(post.id)
+  }
+  
+  return (
+    <div>
+      <p>{post.content}</p>
+      <button onClick={handleLike}>
+        ❤️ {optimisticLikes}
+      </button>
+    </div>
+  )
+}
+```
+
+## Data Mutations & Revalidation
+
+### revalidatePath
+Invalidate cached data for a path:
+
+```typescript
+'use server'
+
+import { revalidatePath } from 'next/cache'
+
+export async function createPost(formData: FormData) {
+  await db.post.create({ data: {...} })
+  
+  // Revalidate the posts page
+  revalidatePath('/posts')
+  
+  // Revalidate with layout
+  revalidatePath('/posts', 'layout')
+}
+```
+
+### revalidateTag
+Invalidate cached data by tag:
+
+```typescript
+'use server'
+
+import { revalidateTag } from 'next/cache'
+
+export async function updateProduct(id: string, data: ProductData) {
+  await db.product.update({ where: { id }, data })
+  
+  // Revalidate all queries tagged with 'products'
+  revalidateTag('products')
+}
+```
+
+### redirect
+Redirect after mutation:
+
+```typescript
+'use server'
+
+import { redirect } from 'next/navigation'
+
+export async function createPost(formData: FormData) {
+  const post = await db.post.create({ data: {...} })
+  
+  // Redirect to the new post
+  redirect(`/posts/${post.id}`)
+}
+```
+
+## Caching with Server Components
+
+### cache Function
+Deduplicate requests within a render:
+
+```typescript
+import { cache } from 'react'
+
+export const getUser = cache(async (id: string) => {
+  return await db.user.findUnique({ where: { id } })
+})
+
+// Called multiple times but only fetches once per render
+const Page = async () => {
+  const user1 = await getUser('123')
+  const user2 = await getUser('123')  // Uses cached result
+  
+  return <div>...</div>
+}
+```
+
+### Next.js fetch Caching
+```typescript
+// Cached by default
+const data = await fetch('https://api.example.com/data')
+
+// Revalidate every 60 seconds
+const data = await fetch('https://api.example.com/data', {
+  next: { revalidate: 60 }
+})
+
+// Never cache
+const data = await fetch('https://api.example.com/data', {
+  cache: 'no-store'
+})
+
+// Tag for revalidation
+const data = await fetch('https://api.example.com/data', {
+  next: { tags: ['products'] }
+})
+```
+
+## Best Practices
+
+### 1. Component Placement
+- Keep interactive components client-side
+- Use server components for data fetching
+- Place 'use client' as deep as possible in tree
+
+### 2. Data Fetching
+- Fetch in parallel when possible
+- Use Suspense for streaming
+- Cache expensive operations
+
+### 3. Server Functions
+- Validate all inputs
+- Check authentication/authorization
+- Handle errors gracefully
+- Return serializable data only
+
+### 4. Performance
+- Minimize client JavaScript
+- Use streaming for slow queries
+- Implement proper caching
+- Optimize database queries
+
+### 5. Security
+- Never expose secrets to client
+- Validate server function inputs
+- Use environment variables
+- Implement rate limiting
+
+## Common Patterns
+
+### Layout with Dynamic Data
+```typescript
+// app/layout.tsx
+const RootLayout = async ({ children }: { children: React.ReactNode }) => {
+  const user = await getCurrentUser()
+  
+  return (
+    <html>
+      <body>
+        <Header user={user} />
+        {children}
+        <Footer />
+      </body>
+    </html>
+  )
+}
+```
+
+### Loading States
+```typescript
+// app/products/loading.tsx
+export default function Loading() {
+  return <ProductsSkeleton />
+}
+
+// app/products/page.tsx
+const ProductsPage = async () => {
+  const products = await fetchProducts()
+  return <ProductsList products={products} />
+}
+```
+
+### Error Boundaries
+```typescript
+// app/products/error.tsx
+'use client'
+
+export default function Error({
+  error,
+  reset
+}: {
+  error: Error
+  reset: () => void
+}) {
+  return (
+    <div>
+      <h2>Something went wrong!</h2>
+      <p>{error.message}</p>
+      <button onClick={reset}>Try again</button>
+    </div>
+  )
+}
+```
+
+### Search with Server Functions
+```typescript
+'use client'
+
+import { searchProducts } from './actions'
+import { useDeferredValue, useState, useEffect } from 'react'
+
+const SearchPage = () => {
+  const [query, setQuery] = useState('')
+  const [results, setResults] = useState([])
+  const deferredQuery = useDeferredValue(query)
+  
+  useEffect(() => {
+    if (deferredQuery) {
+      searchProducts(deferredQuery).then(setResults)
+    }
+  }, [deferredQuery])
+  
+  return (
+    <>
+      <input 
+        value={query} 
+        onChange={e => setQuery(e.target.value)}
+      />
+      <ResultsList results={results} />
+    </>
+  )
+}
+```
+
+## Troubleshooting
+
+### Common Issues
+
+1. **"Cannot use hooks in Server Component"**
+   - Add 'use client' directive
+   - Move state logic to client component
+
+2. **"Functions cannot be passed to Client Components"**
+   - Use Server Functions instead
+   - Pass data, not functions
+
+3. **Hydration mismatches**
+   - Ensure server and client render same HTML
+   - Use useEffect for browser-only code
+
+4. **Slow initial load**
+   - Implement Suspense boundaries
+   - Use streaming rendering
+   - Optimize database queries

+
+# TypeScript Skill
+
+This skill provides comprehensive knowledge and patterns for working with TypeScript effectively in modern applications.
+
+## When to Use This Skill
+
+Use this skill when:
+- Writing or refactoring TypeScript code
+- Designing type-safe APIs and interfaces
+- Working with advanced type system features (generics, conditional types, mapped types)
+- Configuring TypeScript projects (tsconfig.json)
+- Troubleshooting type errors
+- Implementing type-safe patterns with libraries (React, TanStack, etc.)
+- Converting JavaScript code to TypeScript
+
+## Core Concepts
+
+### Type System Fundamentals
+
+TypeScript provides static typing for JavaScript with a powerful type system that includes:
+- Primitive types (string, number, boolean, null, undefined, symbol, bigint)
+- Object types (interfaces, type aliases, classes)
+- Array and tuple types
+- Union and intersection types
+- Literal types and template literal types
+- Type inference and type narrowing
+- Generic types with constraints
+- Conditional types and mapped types
+
+### Type Inference
+
+Leverage TypeScript's type inference to write less verbose code:
+- Let TypeScript infer return types when obvious
+- Use type inference for variable declarations
+- Rely on generic type inference in function calls
+- Use `as const` for immutable literal types
+
+### Type Safety Patterns
+
+Implement type-safe patterns:
+- Use discriminated unions for state management
+- Implement type guards for runtime type checking
+- Use branded types for nominal typing
+- Leverage conditional types for API design
+- Use template literal types for string manipulation
+
+## Key Workflows
+
+### 1. Designing Type-Safe APIs
+
+When designing APIs, follow these patterns:
+
+**Interface vs Type Alias:**
+- Use `interface` for object shapes that may be extended
+- Use `type` for unions, intersections, and complex type operations
+- Use `type` with mapped types and conditional types
+
+**Generic Constraints:**
+```typescript
+// Use extends for generic constraints
+function getValue<T extends { id: string }>(item: T): string {
+  return item.id
+}
+```
+
+**Discriminated Unions:**
+```typescript
+// Use for type-safe state machines
+type State =
+  | { status: 'idle' }
+  | { status: 'loading' }
+  | { status: 'success'; data: Data }
+  | { status: 'error'; error: Error }
+```
+
+### 2. Working with Utility Types
+
+Use built-in utility types for common transformations:
+- `Partial<T>` - Make all properties optional
+- `Required<T>` - Make all properties required
+- `Readonly<T>` - Make all properties readonly
+- `Pick<T, K>` - Select specific properties
+- `Omit<T, K>` - Exclude specific properties
+- `Record<K, T>` - Create object type with specific keys
+- `Exclude<T, U>` - Exclude types from union
+- `Extract<T, U>` - Extract types from union
+- `NonNullable<T>` - Remove null/undefined
+- `ReturnType<T>` - Get function return type
+- `Parameters<T>` - Get function parameter types
+- `Awaited<T>` - Unwrap Promise type
+
+### 3. Advanced Type Patterns
+
+**Mapped Types:**
+```typescript
+// Transform object types
+type Nullable<T> = {
+  [K in keyof T]: T[K] | null
+}
+
+type ReadonlyDeep<T> = {
+  readonly [K in keyof T]: T[K] extends object
+    ? ReadonlyDeep<T[K]>
+    : T[K]
+}
+```
+
+**Conditional Types:**
+```typescript
+// Type-level logic
+type IsArray<T> = T extends Array<any> ? true : false
+
+type Flatten<T> = T extends Array<infer U> ? U : T
+```
+
+**Template Literal Types:**
+```typescript
+// String manipulation at type level
+type EventName<T extends string> = `on${Capitalize<T>}`
+type Route = `/api/${'users' | 'posts'}/${string}`
+```
+
+### 4. Type Narrowing
+
+Use type guards and narrowing techniques:
+
+**typeof guards:**
+```typescript
+if (typeof value === 'string') {
+  // value is string here
+}
+```
+
+**instanceof guards:**
+```typescript
+if (error instanceof Error) {
+  // error is Error here
+}
+```
+
+**Custom type guards:**
+```typescript
+function isUser(value: unknown): value is User {
+  return typeof value === 'object' && value !== null && 'id' in value
+}
+```
+
+**Discriminated unions:**
+```typescript
+function handle(state: State) {
+  switch (state.status) {
+    case 'idle':
+      // state is { status: 'idle' }
+      break
+    case 'success':
+      // state is { status: 'success'; data: Data }
+      console.log(state.data)
+      break
+  }
+}
+```
+
+### 5. Working with External Libraries
+
+**Typing Third-Party Libraries:**
+- Install type definitions: `npm install --save-dev @types/package-name`
+- Create custom declarations in `.d.ts` files when types unavailable
+- Use module augmentation to extend existing type definitions
+
+**Declaration Files:**
+```typescript
+// globals.d.ts
+declare global {
+  interface Window {
+    myCustomProperty: string
+  }
+}
+
+export {}
+```
+
+### 6. TypeScript Configuration
+
+Configure `tsconfig.json` for strict type checking:
+
+**Essential Strict Options:**
+```json
+{
+  "compilerOptions": {
+    "strict": true,
+    "noImplicitAny": true,
+    "strictNullChecks": true,
+    "strictFunctionTypes": true,
+    "strictBindCallApply": true,
+    "strictPropertyInitialization": true,
+    "noImplicitThis": true,
+    "alwaysStrict": true,
+    "noUnusedLocals": true,
+    "noUnusedParameters": true,
+    "noImplicitReturns": true,
+    "noFallthroughCasesInSwitch": true,
+    "skipLibCheck": true
+  }
+}
+```
+
+## Best Practices
+
+### 1. Prefer Type Inference Over Explicit Types
+Let TypeScript infer types when they're obvious from context.
+
+### 2. Use Strict Mode
+Enable strict type checking to catch more errors at compile time.
+
+### 3. Avoid `any` Type
+Use `unknown` for truly unknown types, then narrow with type guards.
+
+### 4. Use Const Assertions
+Use `as const` for immutable values and narrow literal types.
+
+### 5. Leverage Discriminated Unions
+Use for state machines and variant types for better type safety.
+
+### 6. Create Reusable Generic Types
+Extract common type patterns into reusable generics.
+
+### 7. Use Branded Types for Nominal Typing
+Create distinct types for values with same structure but different meaning.
+
+### 8. Document Complex Types
+Add JSDoc comments to explain non-obvious type decisions.
+
+### 9. Use Type-Only Imports
+Use `import type` for type-only imports to aid tree-shaking.
+
+### 10. Handle Errors with Type Guards
+Use type guards to safely work with error objects.
+
+## Common Patterns
+
+### React Component Props
+```typescript
+// Use interface for component props
+interface ButtonProps {
+  variant?: 'primary' | 'secondary'
+  size?: 'sm' | 'md' | 'lg'
+  onClick?: () => void
+  children: React.ReactNode
+}
+
+export function Button({ variant = 'primary', size = 'md', onClick, children }: ButtonProps) {
+  // implementation
+}
+```
+
+### API Response Types
+```typescript
+// Use discriminated unions for API responses
+type ApiResponse<T> =
+  | { success: true; data: T }
+  | { success: false; error: string }
+
+// Helper for safe API calls
+async function fetchData<T>(url: string): Promise<ApiResponse<T>> {
+  try {
+    const response = await fetch(url)
+    const data = await response.json()
+    return { success: true, data }
+  } catch (error) {
+    return { success: false, error: String(error) }
+  }
+}
+```
+
+### Store/State Types
+```typescript
+// Use interfaces for state objects
+interface AppState {
+  user: User | null
+  isAuthenticated: boolean
+  theme: 'light' | 'dark'
+}
+
+// Use type for actions (discriminated union)
+type AppAction =
+  | { type: 'LOGIN'; payload: User }
+  | { type: 'LOGOUT' }
+  | { type: 'SET_THEME'; payload: 'light' | 'dark' }
+```

+
+## Troubleshooting
+
+### Common Type Errors
+
+**Type 'X' is not assignable to type 'Y':**
+- Check if types are compatible
+- Use type assertions when you know better than the compiler
+- Consider using union types or widening the target type
+
+**Object is possibly 'null' or 'undefined':**
+- Use optional chaining: `object?.property`
+- Use nullish coalescing: `value ?? defaultValue`
+- Add type guards or null checks
+
+**Type 'any' implicitly has...**
+- Enable strict mode and fix type definitions
+- Add explicit type annotations
+- Use `unknown` instead of `any` when appropriate
+
+**Cannot find module or its type declarations:**
+- Install type definitions: `@types/package-name`
+- Create custom `.d.ts` declaration file
+- Add to `types` array in tsconfig.json
+
+## Integration with Project Stack
+
+### React 19
+Use TypeScript with React 19 features:
+- Type component props with interfaces
+- Use generic types for hooks
+- Type context providers properly
+- Use `React.FC` sparingly (prefer explicit typing)
+
+### TanStack Ecosystem
+Type TanStack libraries properly:
+- TanStack Query: Type query keys and data
+- TanStack Router: Use typed route definitions
+- TanStack Form: Type form values and validation
+- TanStack Store: Type state and actions
+
+### Zod Integration
+Combine Zod with TypeScript:
+- Use `z.infer<typeof schema>` to extract types from schemas
+- Let Zod handle runtime validation
+- Use TypeScript for compile-time type checking
+

+# TypeScript Examples
+
+This directory contains practical TypeScript examples demonstrating various patterns and features.
+
+## Examples
+
+1. **type-system-basics.ts** - Fundamental TypeScript types and features
+2. **advanced-types.ts** - Generics, conditional types, and mapped types
+3. **react-patterns.ts** - Type-safe React components and hooks
+4. **api-patterns.ts** - API response handling with type safety
+5. **validation.ts** - Runtime validation with Zod and TypeScript
+
+## How to Use
+
+Each example file is self-contained and demonstrates specific TypeScript concepts. They're based on real-world patterns used in the Plebeian Market application and follow best practices for:
+
+- Type safety
+- Error handling
+- Code organization
+- Reusability
+- Maintainability
+
+## Running Examples
+
+These examples are TypeScript files that can be:
+- Copied into your project
+- Used as reference for patterns
+- Modified for your specific needs
+- Run with `ts-node` for testing
+
+```bash
+# Run an example
+npx ts-node examples/type-system-basics.ts
+```
+
+## Learning Path
+
+1. Start with `type-system-basics.ts` to understand fundamentals
+2. Move to `advanced-types.ts` for complex type patterns
+3. Explore `react-patterns.ts` for component typing
+4. Study `api-patterns.ts` for type-safe API handling
+5. Review `validation.ts` for runtime safety
+
+Each example builds on previous concepts, so following this order is recommended for learners.

+# TypeScript Quick Reference
+
+Quick lookup guide for common TypeScript patterns and syntax.
+
+## Basic Types
+
+```typescript
+// Primitives
+string, number, boolean, null, undefined, symbol, bigint
+
+// Special types
+any         // Avoid - disables type checking
+unknown     // Type-safe alternative to any
+void        // No return value
+never       // Never returns
+
+// Arrays
+number[]
+Array<string>
+readonly number[]
+
+// Tuples
+[string, number]
+[x: number, y: number]
+
+// Objects
+{ name: string; age: number }
+Record<string, number>
+```
+
+## Type Declarations
+
+```typescript
+// Interface
+interface User {
+  id: string
+  name: string
+  age?: number          // Optional
+  readonly createdAt: Date  // Readonly
+}
+
+// Type alias
+type Status = 'idle' | 'loading' | 'success' | 'error'
+type ID = string | number
+type Point = { x: number; y: number }
+
+// Function type
+type Callback = (data: string) => void
+type MathOp = (a: number, b: number) => number
+```
+
+## Union & Intersection
+
+```typescript
+// Union (OR)
+string | number
+type Result = Success | Error
+
+// Intersection (AND)
+A & B
+type Combined = User & Timestamped
+
+// Discriminated union
+type State =
+  | { status: 'idle' }
+  | { status: 'loading' }
+  | { status: 'success'; data: Data }
+  | { status: 'error'; error: Error }
+```
+
+## Generics
+
+```typescript
+// Generic function
+function identity<T>(value: T): T
+
+// Generic interface
+interface Box<T> { value: T }
+
+// Generic with constraint
+function getProperty<T, K extends keyof T>(obj: T, key: K): T[K]
+
+// Multiple type parameters
+function merge<T, U>(a: T, b: U): T & U
+
+// Default type parameter
+interface Response<T = unknown> { data: T }
+```
+
+## Utility Types
+
+```typescript
+Partial<T>              // Make all optional
+Required<T>             // Make all required
+Readonly<T>             // Make all readonly
+Pick<T, K>              // Select properties
+Omit<T, K>              // Exclude properties
+Record<K, T>            // Object with specific keys
+Exclude<T, U>           // Remove from union
+Extract<T, U>           // Extract from union
+NonNullable<T>          // Remove null/undefined
+ReturnType<T>           // Get function return type
+Parameters<T>           // Get function parameters
+Awaited<T>              // Unwrap Promise
+```
+
+## Type Guards
+
+```typescript
+// typeof
+if (typeof value === 'string') { }
+
+// instanceof
+if (error instanceof Error) { }
+
+// in operator
+if ('property' in object) { }
+
+// Custom type guard
+function isUser(value: unknown): value is User {
+  return typeof value === 'object' && value !== null && 'id' in value
+}
+
+// Assertion function
+function assertIsString(value: unknown): asserts value is string {
+  if (typeof value !== 'string') throw new Error()
+}
+```
+
+## Advanced Types
+
+```typescript
+// Conditional types
+type IsString<T> = T extends string ? true : false
+
+// Mapped types
+type Nullable<T> = { [K in keyof T]: T[K] | null }
+
+// Template literal types
+type EventName<T extends string> = `on${Capitalize<T>}`
+
+// Key remapping
+type Getters<T> = {
+  [K in keyof T as `get${Capitalize<string & K>}`]: () => T[K]
+}
+
+// infer keyword
+type Flatten<T> = T extends Array<infer U> ? U : T
+```
+
+## Functions
+
+```typescript
+// Function declaration
+function add(a: number, b: number): number { return a + b }
+
+// Arrow function
+const subtract = (a: number, b: number): number => a - b
+
+// Optional parameters
+function greet(name: string, greeting?: string): string { }
+
+// Default parameters
+function create(name: string, role = 'user'): User { }
+
+// Rest parameters
+function sum(...numbers: number[]): number { }
+
+// Overloads
+function format(value: string): string
+function format(value: number): string
+function format(value: string | number): string { }
+```
+
+## Classes
+
+```typescript
+class User {
+  // Properties
+  private id: string
+  public name: string
+  protected age: number
+  readonly createdAt: Date
+
+  // Constructor
+  constructor(name: string) {
+    this.name = name
+    this.createdAt = new Date()
+  }
+
+  // Methods
+  greet(): string {
+    return `Hello, ${this.name}`
+  }
+
+  // Static
+  static create(name: string): User {
+    return new User(name)
+  }
+
+  // Getters/Setters
+  get displayName(): string {
+    return this.name.toUpperCase()
+  }
+}
+
+// Inheritance
+class Admin extends User {
+  constructor(name: string, public permissions: string[]) {
+    super(name)
+  }
+}
+
+// Abstract class
+abstract class Animal {
+  abstract makeSound(): void
+}
+```
+
+## React Patterns
+
+```typescript
+// Component props
+interface ButtonProps {
+  variant?: 'primary' | 'secondary'
+  onClick?: () => void
+  children: React.ReactNode
+}
+
+export function Button({ variant = 'primary', onClick, children }: ButtonProps) { }
+
+// Generic component
+interface ListProps<T> {
+  items: T[]
+  renderItem: (item: T) => React.ReactNode
+}
+
+export function List<T>({ items, renderItem }: ListProps<T>) { }
+
+// Hooks
+const [state, setState] = useState<string>('')
+const [data, setData] = useState<User | null>(null)
+
+// Context
+interface AuthContextType {
+  user: User | null
+  login: () => Promise<void>
+}
+
+const AuthContext = createContext<AuthContextType | undefined>(undefined)
+
+export function useAuth(): AuthContextType {
+  const context = useContext(AuthContext)
+  if (!context) throw new Error('useAuth must be used within AuthProvider')
+  return context
+}
+```
+
+## Common Patterns
+
+### Result Type
+```typescript
+type Result<T, E = Error> =
+  | { success: true; data: T }
+  | { success: false; error: E }
+```
+
+### Option Type
+```typescript
+type Option<T> = Some<T> | None
+interface Some<T> { _tag: 'Some'; value: T }
+interface None { _tag: 'None' }
+```
+
+### Branded Types
+```typescript
+type Brand<K, T> = K & { __brand: T }
+type UserId = Brand<string, 'UserId'>
+```
+
+### Named Returns (Go-style)
+```typescript
+function parseJSON(json: string): { data: unknown | null; err: Error | null } {
+  let data: unknown | null = null
+  let err: Error | null = null
+  
+  try {
+    data = JSON.parse(json)
+  } catch (error) {
+    err = error instanceof Error ? error : new Error(String(error))
+  }
+  
+  return { data, err }
+}
+```
+
+## Type Assertions
+
+```typescript
+// as syntax (preferred)
+const value = input as string
+
+// Angle bracket syntax (not in JSX)
+const value = <string>input
+
+// as const
+const config = { host: 'localhost' } as const
+
+// Non-null assertion (use sparingly)
+const element = document.getElementById('app')!
+```
+
+## Type Narrowing
+
+```typescript
+// Control flow
+if (value !== null) {
+  // value is non-null here
+}
+
+// Switch with discriminated unions
+switch (state.status) {
+  case 'success':
+    console.log(state.data) // TypeScript knows data exists
+    break
+  case 'error':
+    console.log(state.error) // TypeScript knows error exists
+    break
+}
+
+// Optional chaining
+user?.profile?.name
+
+// Nullish coalescing
+const name = user?.name ?? 'Anonymous'
+```
+
+## Module Syntax
+
+```typescript
+// Named exports
+export function helper() { }
+export const CONFIG = { }
+
+// Default export
+export default class App { }
+
+// Type-only imports/exports
+import type { User } from './types'
+export type { User }
+
+// Namespace imports
+import * as utils from './utils'
+```
+
+## TSConfig Essentials
+
+```json
+{
+  "compilerOptions": {
+    "strict": true,
+    "target": "ES2022",
+    "module": "ESNext",
+    "moduleResolution": "bundler",
+    "jsx": "react-jsx",
+    "esModuleInterop": true,
+    "skipLibCheck": true,
+    "resolveJsonModule": true
+  }
+}
+```
+
+## Common Errors & Fixes
+
+| Error | Fix |
+|-------|-----|
+| Type 'X' is not assignable to type 'Y' | Check type compatibility, use type assertion if needed |
+| Object is possibly 'null' | Use optional chaining `?.` or null check |
+| Cannot find module | Install `@types/package-name` |
+| Implicit any | Add type annotation or enable strict mode |
+| Property does not exist | Check object shape, use type guard |
+
+## Best Practices
+
+1. Enable `strict` mode in tsconfig.json
+2. Avoid `any`, use `unknown` instead
+3. Use discriminated unions for state
+4. Leverage type inference
+5. Use `const` assertions for immutable data
+6. Create custom type guards for runtime safety
+7. Use utility types instead of recreating
+8. Document complex types with JSDoc
+9. Prefer interfaces for objects, types for unions
+10. Use branded types for domain-specific primitives

+# TypeScript Common Patterns Reference
+
+This document contains commonly used TypeScript patterns and idioms from real-world applications.
+
+## React Patterns
+
+### Component Props
+
+```typescript
+// Basic props with children
+interface ButtonProps {
+  variant?: 'primary' | 'secondary' | 'tertiary'
+  size?: 'sm' | 'md' | 'lg'
+  disabled?: boolean
+  onClick?: () => void
+  children: React.ReactNode
+}
+
+export function Button({
+  variant = 'primary',
+  size = 'md',
+  disabled = false,
+  onClick,
+  children,
+}: ButtonProps) {
+  return (
+    <button className={`btn-${variant} btn-${size}`} disabled={disabled} onClick={onClick}>
+      {children}
+    </button>
+  )
+}
+
+// Props extending HTML attributes
+interface InputProps extends React.InputHTMLAttributes<HTMLInputElement> {
+  label?: string
+  error?: string
+}
+
+export function Input({ label, error, ...inputProps }: InputProps) {
+  return (
+    <div>
+      {label && <label>{label}</label>}
+      <input {...inputProps} />
+      {error && <span>{error}</span>}
+    </div>
+  )
+}
+
+// Generic component props
+interface ListProps<T> {
+  items: T[]
+  renderItem: (item: T) => React.ReactNode
+  keyExtractor: (item: T) => string
+}
+
+export function List<T>({ items, renderItem, keyExtractor }: ListProps<T>) {
+  return (
+    <ul>
+      {items.map((item) => (
+        <li key={keyExtractor(item)}>{renderItem(item)}</li>
+      ))}
+    </ul>
+  )
+}
+```
+
+### Hooks
+
+```typescript
+// Custom hook with return type
+function useLocalStorage<T>(key: string, initialValue: T): [T, (value: T) => void] {
+  const [storedValue, setStoredValue] = useState<T>(() => {
+    try {
+      const item = window.localStorage.getItem(key)
+      return item ? JSON.parse(item) : initialValue
+    } catch (error) {
+      return initialValue
+    }
+  })
+
+  const setValue = (value: T) => {
+    setStoredValue(value)
+    window.localStorage.setItem(key, JSON.stringify(value))
+  }
+
+  return [storedValue, setValue]
+}
+
+// Hook with options object
+interface UseFetchOptions<T> {
+  initialData?: T
+  onSuccess?: (data: T) => void
+  onError?: (error: Error) => void
+}
+
+function useFetch<T>(url: string, options?: UseFetchOptions<T>) {
+  const [data, setData] = useState<T | undefined>(options?.initialData)
+  const [loading, setLoading] = useState(false)
+  const [error, setError] = useState<Error | null>(null)
+
+  useEffect(() => {
+    let isCancelled = false
+
+    const fetchData = async () => {
+      setLoading(true)
+      try {
+        const response = await fetch(url)
+        const json = await response.json()
+        if (!isCancelled) {
+          setData(json)
+          options?.onSuccess?.(json)
+        }
+      } catch (err) {
+        if (!isCancelled) {
+          const error = err instanceof Error ? err : new Error(String(err))
+          setError(error)
+          options?.onError?.(error)
+        }
+      } finally {
+        if (!isCancelled) {
+          setLoading(false)
+        }
+      }
+    }
+
+    fetchData()
+
+    return () => {
+      isCancelled = true
+    }
+  }, [url])
+
+  return { data, loading, error }
+}
+```
+
+### Context
+
+```typescript
+// Type-safe context
+interface AuthContextType {
+  user: User | null
+  login: (email: string, password: string) => Promise<void>
+  logout: () => void
+  isAuthenticated: boolean
+}
+
+const AuthContext = createContext<AuthContextType | undefined>(undefined)
+
+export function AuthProvider({ children }: { children: React.ReactNode }) {
+  const [user, setUser] = useState<User | null>(null)
+
+  const login = async (email: string, password: string) => {
+    // Login logic
+    const user = await api.login(email, password)
+    setUser(user)
+  }
+
+  const logout = () => {
+    setUser(null)
+  }
+
+  const value: AuthContextType = {
+    user,
+    login,
+    logout,
+    isAuthenticated: user !== null,
+  }
+
+  return <AuthContext.Provider value={value}>{children}</AuthContext.Provider>
+}
+
+// Custom hook with proper error handling
+export function useAuth(): AuthContextType {
+  const context = useContext(AuthContext)
+  if (context === undefined) {
+    throw new Error('useAuth must be used within AuthProvider')
+  }
+  return context
+}
+```
+
+## API Response Patterns
+
+### Result Type Pattern
+
+```typescript
+// Discriminated union for API responses
+type Result<T, E = Error> =
+  | { success: true; data: T }
+  | { success: false; error: E }
+
+// Helper functions
+function success<T>(data: T): Result<T> {
+  return { success: true, data }
+}
+
+function failure<E = Error>(error: E): Result<never, E> {
+  return { success: false, error }
+}
+
+// Usage
+async function fetchUser(id: string): Promise<Result<User>> {
+  try {
+    const response = await fetch(`/api/users/${id}`)
+    if (!response.ok) {
+      return failure(new Error(`HTTP ${response.status}`))
+    }
+    const data = await response.json()
+    return success(data)
+  } catch (error) {
+    return failure(error instanceof Error ? error : new Error(String(error)))
+  }
+}
+
+// Consuming the result
+const result = await fetchUser('123')
+if (result.success) {
+  console.log(result.data.name) // Type-safe access
+} else {
+  console.error(result.error.message) // Type-safe error handling
+}
+```
+
+### Option Type Pattern
+
+```typescript
+// Option/Maybe type for nullable values
+type Option<T> = Some<T> | None
+
+interface Some<T> {
+  readonly _tag: 'Some'
+  readonly value: T
+}
+
+interface None {
+  readonly _tag: 'None'
+}
+
+// Constructors
+function some<T>(value: T): Option<T> {
+  return { _tag: 'Some', value }
+}
+
+function none(): Option<never> {
+  return { _tag: 'None' }
+}
+
+// Helper functions
+function isSome<T>(option: Option<T>): option is Some<T> {
+  return option._tag === 'Some'
+}
+
+function isNone<T>(option: Option<T>): option is None {
+  return option._tag === 'None'
+}
+
+function map<T, U>(option: Option<T>, fn: (value: T) => U): Option<U> {
+  return isSome(option) ? some(fn(option.value)) : none()
+}
+
+function getOrElse<T>(option: Option<T>, defaultValue: T): T {
+  return isSome(option) ? option.value : defaultValue
+}
+
+// Usage
+function findUser(id: string): Option<User> {
+  const user = users.find((u) => u.id === id)
+  return user ? some(user) : none()
+}
+
+const user = findUser('123')
+const userName = getOrElse(map(user, (u) => u.name), 'Unknown')
+```
+
+## State Management Patterns
+
+### Discriminated Union for State
+
+```typescript
+// State machine using discriminated unions
+type FetchState<T> =
+  | { status: 'idle' }
+  | { status: 'loading' }
+  | { status: 'success'; data: T }
+  | { status: 'error'; error: Error }
+
+// Reducer pattern
+type FetchAction<T> =
+  | { type: 'FETCH_START' }
+  | { type: 'FETCH_SUCCESS'; payload: T }
+  | { type: 'FETCH_ERROR'; error: Error }
+  | { type: 'RESET' }
+
+function fetchReducer<T>(state: FetchState<T>, action: FetchAction<T>): FetchState<T> {
+  switch (action.type) {
+    case 'FETCH_START':
+      return { status: 'loading' }
+    case 'FETCH_SUCCESS':
+      return { status: 'success', data: action.payload }
+    case 'FETCH_ERROR':
+      return { status: 'error', error: action.error }
+    case 'RESET':
+      return { status: 'idle' }
+  }
+}
+
+// Usage in component
+function UserProfile({ userId }: { userId: string }) {
+  const [state, dispatch] = useReducer(fetchReducer<User>, { status: 'idle' })
+
+  useEffect(() => {
+    dispatch({ type: 'FETCH_START' })
+    fetchUser(userId)
+      .then((user) => dispatch({ type: 'FETCH_SUCCESS', payload: user }))
+      .catch((error) => dispatch({ type: 'FETCH_ERROR', error }))
+  }, [userId])
+
+  switch (state.status) {
+    case 'idle':
+      return <div>Ready to load</div>
+    case 'loading':
+      return <div>Loading...</div>
+    case 'success':
+      return <div>{state.data.name}</div>
+    case 'error':
+      return <div>Error: {state.error.message}</div>
+  }
+}
+```
+
+### Store Pattern
+
+```typescript
+// Type-safe store implementation
+interface Store<T> {
+  getState: () => T
+  setState: (partial: Partial<T>) => void
+  subscribe: (listener: (state: T) => void) => () => void
+}
+
+function createStore<T>(initialState: T): Store<T> {
+  let state = initialState
+  const listeners = new Set<(state: T) => void>()
+
+  return {
+    getState: () => state,
+    setState: (partial) => {
+      state = { ...state, ...partial }
+      listeners.forEach((listener) => listener(state))
+    },
+    subscribe: (listener) => {
+      listeners.add(listener)
+      return () => listeners.delete(listener)
+    },
+  }
+}
+
+// Usage
+interface AppState {
+  user: User | null
+  theme: 'light' | 'dark'
+}
+
+const store = createStore<AppState>({
+  user: null,
+  theme: 'light',
+})
+
+// React hook integration
+function useStore<T, U>(store: Store<T>, selector: (state: T) => U): U {
+  const [value, setValue] = useState(() => selector(store.getState()))
+
+  useEffect(() => {
+    const unsubscribe = store.subscribe((state) => {
+      setValue(selector(state))
+    })
+    return unsubscribe
+  }, [store, selector])
+
+  return value
+}
+
+// Usage in component
+function ThemeToggle() {
+  const theme = useStore(store, (state) => state.theme)
+
+  return (
+    <button
+      onClick={() => store.setState({ theme: theme === 'light' ? 'dark' : 'light' })}
+    >
+      Toggle Theme
+    </button>
+  )
+}
+```
+
+## Form Patterns
+
+### Form State Management
+
+```typescript
+// Generic form state
+interface FormState<T> {
+  values: T
+  errors: Partial<Record<keyof T, string>>
+  touched: Partial<Record<keyof T, boolean>>
+  isSubmitting: boolean
+}
+
+// Form hook
+function useForm<T extends Record<string, any>>(
+  initialValues: T,
+  validate: (values: T) => Partial<Record<keyof T, string>>,
+) {
+  const [state, setState] = useState<FormState<T>>({
+    values: initialValues,
+    errors: {},
+    touched: {},
+    isSubmitting: false,
+  })
+
+  const handleChange = <K extends keyof T>(field: K, value: T[K]) => {
+    setState((prev) => ({
+      ...prev,
+      values: { ...prev.values, [field]: value },
+      errors: { ...prev.errors, [field]: undefined },
+    }))
+  }
+
+  const handleBlur = <K extends keyof T>(field: K) => {
+    setState((prev) => ({
+      ...prev,
+      touched: { ...prev.touched, [field]: true },
+    }))
+  }
+
+  const handleSubmit = async (onSubmit: (values: T) => Promise<void>) => {
+    const errors = validate(state.values)
+
+    if (Object.keys(errors).length > 0) {
+      setState((prev) => ({
+        ...prev,
+        errors,
+        touched: Object.keys(state.values).reduce(
+          (acc, key) => ({ ...acc, [key]: true }),
+          {},
+        ),
+      }))
+      return
+    }
+
+    setState((prev) => ({ ...prev, isSubmitting: true }))
+    try {
+      await onSubmit(state.values)
+    } finally {
+      setState((prev) => ({ ...prev, isSubmitting: false }))
+    }
+  }
+
+  return {
+    values: state.values,
+    errors: state.errors,
+    touched: state.touched,
+    isSubmitting: state.isSubmitting,
+    handleChange,
+    handleBlur,
+    handleSubmit,
+  }
+}
+
+// Usage
+interface LoginFormValues {
+  email: string
+  password: string
+}
+
+function LoginForm() {
+  const form = useForm<LoginFormValues>(
+    { email: '', password: '' },
+    (values) => {
+      const errors: Partial<Record<keyof LoginFormValues, string>> = {}
+      if (!values.email) {
+        errors.email = 'Email is required'
+      }
+      if (!values.password) {
+        errors.password = 'Password is required'
+      }
+      return errors
+    },
+  )
+
+  return (
+    <form
+      onSubmit={(e) => {
+        e.preventDefault()
+        form.handleSubmit(async (values) => {
+          await login(values.email, values.password)
+        })
+      }}
+    >
+      <input
+        value={form.values.email}
+        onChange={(e) => form.handleChange('email', e.target.value)}
+        onBlur={() => form.handleBlur('email')}
+      />
+      {form.touched.email && form.errors.email && <span>{form.errors.email}</span>}
+
+      <input
+        type="password"
+        value={form.values.password}
+        onChange={(e) => form.handleChange('password', e.target.value)}
+        onBlur={() => form.handleBlur('password')}
+      />
+      {form.touched.password && form.errors.password && (
+        <span>{form.errors.password}</span>
+      )}
+
+      <button type="submit" disabled={form.isSubmitting}>
+        Login
+      </button>
+    </form>
+  )
+}
+```
+
+## Validation Patterns
+
+### Zod Integration
+
+```typescript
+import { z } from 'zod'
+
+// Schema definition
+const userSchema = z.object({
+  id: z.string().uuid(),
+  name: z.string().min(1).max(100),
+  email: z.string().email(),
+  age: z.number().int().min(0).max(120),
+  role: z.enum(['admin', 'user', 'guest']),
+})
+
+// Extract type from schema
+type User = z.infer<typeof userSchema>
+
+// Validation function
+function validateUser(data: unknown): Result<User> {
+  const result = userSchema.safeParse(data)
+  if (result.success) {
+    return { success: true, data: result.data }
+  }
+  return {
+    success: false,
+    error: new Error(result.error.errors.map((e) => e.message).join(', ')),
+  }
+}
+
+// API integration
+async function createUser(data: unknown): Promise<Result<User>> {
+  const validation = validateUser(data)
+  if (!validation.success) {
+    return validation
+  }
+
+  try {
+    const response = await fetch('/api/users', {
+      method: 'POST',
+      headers: { 'Content-Type': 'application/json' },
+      body: JSON.stringify(validation.data),
+    })
+
+    if (!response.ok) {
+      return failure(new Error(`HTTP ${response.status}`))
+    }
+
+    const user = await response.json()
+    return success(user)
+  } catch (error) {
+    return failure(error instanceof Error ? error : new Error(String(error)))
+  }
+}
+```
+
+## Builder Pattern
+
+```typescript
+// Fluent builder pattern
+class QueryBuilder<T> {
+  private filters: Array<(item: T) => boolean> = []
+  private sortFn?: (a: T, b: T) => number
+  private limitValue?: number
+
+  where(predicate: (item: T) => boolean): this {
+    this.filters.push(predicate)
+    return this
+  }
+
+  sortBy(compareFn: (a: T, b: T) => number): this {
+    this.sortFn = compareFn
+    return this
+  }
+
+  limit(count: number): this {
+    this.limitValue = count
+    return this
+  }
+
+  execute(data: T[]): T[] {
+    let result = data
+
+    // Apply filters
+    this.filters.forEach((filter) => {
+      result = result.filter(filter)
+    })
+
+    // Apply sorting
+    if (this.sortFn) {
+      result = result.sort(this.sortFn)
+    }
+
+    // Apply limit
+    if (this.limitValue !== undefined) {
+      result = result.slice(0, this.limitValue)
+    }
+
+    return result
+  }
+}
+
+// Usage
+interface Product {
+  id: string
+  name: string
+  price: number
+  category: string
+}
+
+const products: Product[] = [
+  /* ... */
+]
+
+const query = new QueryBuilder<Product>()
+  .where((p) => p.category === 'electronics')
+  .where((p) => p.price < 1000)
+  .sortBy((a, b) => a.price - b.price)
+  .limit(10)
+  .execute(products)
+```
+
+## Factory Pattern
+
+```typescript
+// Abstract factory pattern with TypeScript
+interface Button {
+  render: () => string
+  onClick: () => void
+}
+
+interface ButtonFactory {
+  createButton: (label: string, onClick: () => void) => Button
+}
+
+class PrimaryButton implements Button {
+  constructor(private label: string, private clickHandler: () => void) {}
+
+  render() {
+    return `<button class="primary">${this.label}</button>`
+  }
+
+  onClick() {
+    this.clickHandler()
+  }
+}
+
+class SecondaryButton implements Button {
+  constructor(private label: string, private clickHandler: () => void) {}
+
+  render() {
+    return `<button class="secondary">${this.label}</button>`
+  }
+
+  onClick() {
+    this.clickHandler()
+  }
+}
+
+class PrimaryButtonFactory implements ButtonFactory {
+  createButton(label: string, onClick: () => void): Button {
+    return new PrimaryButton(label, onClick)
+  }
+}
+
+class SecondaryButtonFactory implements ButtonFactory {
+  createButton(label: string, onClick: () => void): Button {
+    return new SecondaryButton(label, onClick)
+  }
+}
+
+// Usage
+function createUI(factory: ButtonFactory) {
+  const button = factory.createButton('Click me', () => console.log('Clicked!'))
+  return button.render()
+}
+```
+
+## Named Return Variables Pattern
+
+```typescript
+// Following Go-style named returns
+function parseUser(data: unknown): { user: User | null; err: Error | null } {
+  let user: User | null = null
+  let err: Error | null = null
+
+  try {
+    user = userSchema.parse(data)
+  } catch (error) {
+    err = error instanceof Error ? error : new Error(String(error))
+  }
+
+  return { user, err }
+}
+
+// With explicit naming
+function fetchData(url: string): {
+  data: unknown | null
+  status: number
+  err: Error | null
+} {
+  let data: unknown | null = null
+  let status = 0
+  let err: Error | null = null
+
+  try {
+    const response = fetch(url)
+    // Process response
+  } catch (error) {
+    err = error instanceof Error ? error : new Error(String(error))
+  }
+
+  return { data, status, err }
+}
+```
+
+## Best Practices
+
+1. **Use discriminated unions** for type-safe state management
+2. **Leverage generic types** for reusable components and hooks
+3. **Extract types from Zod schemas** for runtime + compile-time safety
+4. **Use Result/Option types** for explicit error handling
+5. **Create builder patterns** for complex object construction
+6. **Use factory patterns** for flexible object creation
+7. **Type context properly** to catch usage errors at compile time
+8. **Prefer const assertions** for immutable configurations
+9. **Use branded types** for domain-specific primitives
+10. **Document patterns** with JSDoc for team knowledge sharing

+# TypeScript Type System Reference
+
+## Overview
+
+TypeScript's type system is structural (duck-typed) rather than nominal. Two types are compatible if their structure matches, regardless of their names.
+
+## Primitive Types
+
+### Basic Primitives
+
+```typescript
+let str: string = 'hello'
+let num: number = 42
+let bool: boolean = true
+let nul: null = null
+let undef: undefined = undefined
+let sym: symbol = Symbol('key')
+let big: bigint = 100n
+```
+
+### Special Types
+
+**any** - Disables type checking (avoid when possible):
+```typescript
+let anything: any = 'string'
+anything = 42 // OK
+anything.nonExistent() // OK at compile time, error at runtime
+```
+
+**unknown** - Type-safe alternative to any (requires type checking):
+```typescript
+let value: unknown = 'string'
+// value.toUpperCase() // Error: must narrow type first
+
+if (typeof value === 'string') {
+  value.toUpperCase() // OK after narrowing
+}
+```
+
+**void** - Absence of a value (function return type):
+```typescript
+function log(message: string): void {
+  console.log(message)
+}
+```
+
+**never** - Value that never occurs (exhaustive checks, infinite loops):
+```typescript
+function throwError(message: string): never {
+  throw new Error(message)
+}
+
+function exhaustiveCheck(value: never): never {
+  throw new Error(`Unhandled case: ${value}`)
+}
+```
+
+## Object Types
+
+### Interfaces
+
+```typescript
+// Basic interface
+interface User {
+  id: string
+  name: string
+  email: string
+}
+
+// Optional properties
+interface Product {
+  id: string
+  name: string
+  description?: string // Optional
+}
+
+// Readonly properties
+interface Config {
+  readonly apiUrl: string
+  readonly timeout: number
+}
+
+// Index signatures
+interface Dictionary {
+  [key: string]: string
+}
+
+// Method signatures
+interface Calculator {
+  add(a: number, b: number): number
+  subtract(a: number, b: number): number
+}
+
+// Extending interfaces
+interface Employee extends User {
+  role: string
+  department: string
+}
+
+// Multiple inheritance
+interface Admin extends User, Employee {
+  permissions: string[]
+}
+```
+
+### Type Aliases
+
+```typescript
+// Basic type alias
+type ID = string | number
+
+// Object type
+type Point = {
+  x: number
+  y: number
+}
+
+// Union type
+type Status = 'idle' | 'loading' | 'success' | 'error'
+
+// Intersection type
+type Timestamped = {
+  createdAt: Date
+  updatedAt: Date
+}
+
+type TimestampedUser = User & Timestamped
+
+// Function type
+type Callback = (data: string) => void
+
+// Generic type alias
+type Result<T> = { success: true; data: T } | { success: false; error: string }
+```
+
+### Interface vs Type Alias
+
+**Use interface when:**
+- Defining object shapes
+- Need declaration merging
+- Building public API types that others might extend
+
+**Use type when:**
+- Creating unions or intersections
+- Working with mapped types
+- Need conditional types
+- Defining primitive aliases
+
+## Array and Tuple Types
+
+### Arrays
+
+```typescript
+// Array syntax
+let numbers: number[] = [1, 2, 3]
+let strings: Array<string> = ['a', 'b', 'c']
+
+// Readonly arrays
+let immutable: readonly number[] = [1, 2, 3]
+let alsoImmutable: ReadonlyArray<string> = ['a', 'b']
+```
+
+### Tuples
+
+```typescript
+// Fixed-length, mixed-type arrays
+type Point = [number, number]
+type NamedPoint = [x: number, y: number]
+
+// Optional elements
+type OptionalTuple = [string, number?]
+
+// Rest elements
+type StringNumberBooleans = [string, number, ...boolean[]]
+
+// Readonly tuples
+type ReadonlyPair = readonly [string, number]
+```
+
+## Union and Intersection Types
+
+### Union Types
+
+```typescript
+// Value can be one of several types
+type StringOrNumber = string | number
+
+function format(value: StringOrNumber): string {
+  if (typeof value === 'string') {
+    return value
+  }
+  return value.toString()
+}
+
+// Discriminated unions
+type Shape =
+  | { kind: 'circle'; radius: number }
+  | { kind: 'square'; size: number }
+  | { kind: 'rectangle'; width: number; height: number }
+
+function area(shape: Shape): number {
+  switch (shape.kind) {
+    case 'circle':
+      return Math.PI * shape.radius ** 2
+    case 'square':
+      return shape.size ** 2
+    case 'rectangle':
+      return shape.width * shape.height
+  }
+}
+```
+
+### Intersection Types
+
+```typescript
+// Combine multiple types
+type Draggable = {
+  drag: () => void
+}
+
+type Resizable = {
+  resize: () => void
+}
+
+type UIWidget = Draggable & Resizable
+
+const widget: UIWidget = {
+  drag: () => console.log('dragging'),
+  resize: () => console.log('resizing'),
+}
+```
+
+## Literal Types
+
+### String Literal Types
+
+```typescript
+type Direction = 'north' | 'south' | 'east' | 'west'
+type HttpMethod = 'GET' | 'POST' | 'PUT' | 'DELETE'
+
+function move(direction: Direction) {
+  // direction can only be one of the four values
+}
+```
+
+### Number Literal Types
+
+```typescript
+type DiceValue = 1 | 2 | 3 | 4 | 5 | 6
+type PowerOfTwo = 1 | 2 | 4 | 8 | 16 | 32
+```
+
+### Boolean Literal Types
+
+```typescript
+type Yes = true
+type No = false
+```
+
+### Template Literal Types
+
+```typescript
+// String manipulation at type level
+type EventName<T extends string> = `on${Capitalize<T>}`
+type ClickEvent = EventName<'click'> // "onClick"
+
+// Combining literals
+type Color = 'red' | 'blue' | 'green'
+type Shade = 'light' | 'dark'
+type ColorShade = `${Shade}-${Color}` // "light-red" | "light-blue" | ...
+
+// Extract patterns
+type EmailLocaleIDs = 'welcome_email' | 'email_heading'
+type FooterLocaleIDs = 'footer_title' | 'footer_sendoff'
+type AllLocaleIDs = `${EmailLocaleIDs | FooterLocaleIDs}_id`
+```
+
+## Type Inference
+
+### Automatic Inference
+
+```typescript
+// Type inferred as string
+let message = 'hello'
+
+// Type inferred as number[]
+let numbers = [1, 2, 3]
+
+// Type inferred as { name: string; age: number }
+let person = {
+  name: 'Alice',
+  age: 30,
+}
+
+// Return type inferred
+function add(a: number, b: number) {
+  return a + b // Returns number
+}
+```
+
+### Const Assertions
+
+```typescript
+// Without const assertion
+let colors1 = ['red', 'green', 'blue'] // Type: string[]
+
+// With const assertion
+let colors2 = ['red', 'green', 'blue'] as const // Type: readonly ["red", "green", "blue"]
+
+// Object with const assertion
+const config = {
+  host: 'localhost',
+  port: 8080,
+} as const // All properties become readonly with literal types
+```
+
+### Type Inference in Generics
+
+```typescript
+// Generic type inference from usage
+function identity<T>(value: T): T {
+  return value
+}
+
+let str = identity('hello') // T inferred as string
+let num = identity(42) // T inferred as number
+
+// Multiple type parameters
+function pair<T, U>(first: T, second: U): [T, U] {
+  return [first, second]
+}
+
+let p = pair('hello', 42) // [string, number]
+```
+
+## Type Narrowing
+
+### typeof Guards
+
+```typescript
+function padLeft(value: string, padding: string | number) {
+  if (typeof padding === 'number') {
+    // padding is number here
+    return ' '.repeat(padding) + value
+  }
+  // padding is string here
+  return padding + value
+}
+```
+
+### instanceof Guards
+
+```typescript
+class Dog {
+  bark() {
+    console.log('Woof!')
+  }
+}
+
+class Cat {
+  meow() {
+    console.log('Meow!')
+  }
+}
+
+function makeSound(animal: Dog | Cat) {
+  if (animal instanceof Dog) {
+    animal.bark()
+  } else {
+    animal.meow()
+  }
+}
+```
+
+### in Operator
+
+```typescript
+type Fish = { swim: () => void }
+type Bird = { fly: () => void }
+
+function move(animal: Fish | Bird) {
+  if ('swim' in animal) {
+    animal.swim()
+  } else {
+    animal.fly()
+  }
+}
+```
+
+### Equality Narrowing
+
+```typescript
+function example(x: string | number, y: string | boolean) {
+  if (x === y) {
+    // x and y are both string here
+    x.toUpperCase()
+    y.toLowerCase()
+  }
+}
+```
+
+### Control Flow Analysis
+
+```typescript
+function example(value: string | null) {
+  if (value === null) {
+    return
+  }
+  // value is string here (null eliminated)
+  console.log(value.toUpperCase())
+}
+```
+
+### Type Predicates (Custom Type Guards)
+
+```typescript
+function isString(value: unknown): value is string {
+  return typeof value === 'string'
+}
+
+function example(value: unknown) {
+  if (isString(value)) {
+    // value is string here
+    console.log(value.toUpperCase())
+  }
+}
+
+// More complex example
+interface User {
+  id: string
+  name: string
+}
+
+function isUser(value: unknown): value is User {
+  return (
+    typeof value === 'object' &&
+    value !== null &&
+    'id' in value &&
+    'name' in value &&
+    typeof (value as User).id === 'string' &&
+    typeof (value as User).name === 'string'
+  )
+}
+```
+
+### Assertion Functions
+
+```typescript
+function assert(condition: unknown, message?: string): asserts condition {
+  if (!condition) {
+    throw new Error(message || 'Assertion failed')
+  }
+}
+
+function assertIsString(value: unknown): asserts value is string {
+  if (typeof value !== 'string') {
+    throw new Error('Value must be a string')
+  }
+}
+
+function example(value: unknown) {
+  assertIsString(value)
+  // value is string here
+  console.log(value.toUpperCase())
+}
+```
+
+## Generic Types
+
+### Basic Generics
+
+```typescript
+// Generic function
+function first<T>(items: T[]): T | undefined {
+  return items[0]
+}
+
+// Generic interface
+interface Box<T> {
+  value: T
+}
+
+// Generic type alias
+type Result<T> = { success: true; data: T } | { success: false; error: string }
+
+// Generic class
+class Stack<T> {
+  private items: T[] = []
+
+  push(item: T) {
+    this.items.push(item)
+  }
+
+  pop(): T | undefined {
+    return this.items.pop()
+  }
+}
+```
+
+### Generic Constraints
+
+```typescript
+// Constrain to specific type
+function getProperty<T, K extends keyof T>(obj: T, key: K): T[K] {
+  return obj[key]
+}
+
+// Constrain to interface
+interface HasLength {
+  length: number
+}
+
+function logLength<T extends HasLength>(item: T): void {
+  console.log(item.length)
+}
+
+logLength('string') // OK
+logLength([1, 2, 3]) // OK
+logLength({ length: 10 }) // OK
+// logLength(42) // Error: number doesn't have length
+```
+
+### Default Generic Parameters
+
+```typescript
+interface Response<T = unknown> {
+  data: T
+  status: number
+}
+
+// Uses default
+let response1: Response = { data: 'anything', status: 200 }
+
+// Explicitly typed
+let response2: Response<User> = { data: user, status: 200 }
+```
+
+### Generic Utility Functions
+
+```typescript
+// Pick specific properties
+function pick<T, K extends keyof T>(obj: T, keys: K[]): Pick<T, K> {
+  const result = {} as Pick<T, K>
+  keys.forEach((key) => {
+    result[key] = obj[key]
+  })
+  return result
+}
+
+// Map array
+function map<T, U>(items: T[], fn: (item: T) => U): U[] {
+  return items.map(fn)
+}
+```
+
+## Advanced Type Features
+
+### Conditional Types
+
+```typescript
+// Basic conditional type
+type IsString<T> = T extends string ? true : false
+
+type A = IsString<string> // true
+type B = IsString<number> // false
+
+// Distributive conditional types
+type ToArray<T> = T extends any ? T[] : never
+
+type StrArrOrNumArr = ToArray<string | number> // string[] | number[]
+
+// Infer keyword
+type Flatten<T> = T extends Array<infer U> ? U : T
+
+type Str = Flatten<string[]> // string
+type Num = Flatten<number> // number
+
+// ReturnType implementation
+type MyReturnType<T> = T extends (...args: any[]) => infer R ? R : never
+```
+
+### Mapped Types
+
+```typescript
+// Make all properties optional
+type Partial<T> = {
+  [K in keyof T]?: T[K]
+}
+
+// Make all properties required
+type Required<T> = {
+  [K in keyof T]-?: T[K]
+}
+
+// Make all properties readonly
+type Readonly<T> = {
+  readonly [K in keyof T]: T[K]
+}
+
+// Transform keys
+type Getters<T> = {
+  [K in keyof T as `get${Capitalize<string & K>}`]: () => T[K]
+}
+
+interface Person {
+  name: string
+  age: number
+}
+
+type PersonGetters = Getters<Person>
+// {
+//   getName: () => string
+//   getAge: () => number
+// }
+```
+
+### Key Remapping
+
+```typescript
+// Filter keys
+type RemoveKindField<T> = {
+  [K in keyof T as Exclude<K, 'kind'>]: T[K]
+}
+
+// Conditional key inclusion
+type PickByType<T, U> = {
+  [K in keyof T as T[K] extends U ? K : never]: T[K]
+}
+
+interface Model {
+  id: number
+  name: string
+  age: number
+  email: string
+}
+
+type StringFields = PickByType<Model, string> // { name: string, email: string }
+```
+
+### Recursive Types
+
+```typescript
+// JSON value type
+type JSONValue = string | number | boolean | null | JSONObject | JSONArray
+
+interface JSONObject {
+  [key: string]: JSONValue
+}
+
+interface JSONArray extends Array<JSONValue> {}
+
+// Tree structure
+interface TreeNode<T> {
+  value: T
+  children?: TreeNode<T>[]
+}
+
+// Deep readonly
+type DeepReadonly<T> = {
+  readonly [K in keyof T]: T[K] extends object ? DeepReadonly<T[K]> : T[K]
+}
+```
+
+## Type Compatibility
+
+### Structural Typing
+
+```typescript
+interface Point {
+  x: number
+  y: number
+}
+
+interface Named {
+  name: string
+}
+
+// Compatible if structure matches
+let point: Point = { x: 0, y: 0 }
+let namedPoint = { x: 0, y: 0, name: 'origin' }
+
+point = namedPoint // OK: namedPoint has x and y
+```
+
+### Variance
+
+**Covariance** (return types):
+```typescript
+interface Animal {
+  name: string
+}
+
+interface Dog extends Animal {
+  breed: string
+}
+
+let getDog: () => Dog
+let getAnimal: () => Animal
+
+getAnimal = getDog // OK: Dog is assignable to Animal
+```
+
+**Contravariance** (parameter types):
+```typescript
+let handleAnimal: (animal: Animal) => void
+let handleDog: (dog: Dog) => void
+
+handleDog = handleAnimal // OK: can pass Dog to function expecting Animal
+```
+
+## Index Types
+
+### Index Signatures
+
+```typescript
+// String index
+interface StringMap {
+  [key: string]: string
+}
+
+// Number index
+interface NumberArray {
+  [index: number]: number
+}
+
+// Combine with named properties
+interface MixedInterface {
+  length: number
+  [index: number]: string
+}
+```
+
+### keyof Operator
+
+```typescript
+interface Person {
+  name: string
+  age: number
+}
+
+type PersonKeys = keyof Person // "name" | "age"
+
+function getProperty<T, K extends keyof T>(obj: T, key: K): T[K] {
+  return obj[key]
+}
+```
+
+### Indexed Access Types
+
+```typescript
+interface Person {
+  name: string
+  age: number
+  address: {
+    street: string
+    city: string
+  }
+}
+
+type Name = Person['name'] // string
+type Age = Person['age'] // number
+type Address = Person['address'] // { street: string; city: string }
+type AddressCity = Person['address']['city'] // string
+
+// Access multiple keys
+type NameOrAge = Person['name' | 'age'] // string | number
+```
+
+## Branded Types
+
+```typescript
+// Create nominal types from structural types
+type Brand<K, T> = K & { __brand: T }
+
+type USD = Brand<number, 'USD'>
+type EUR = Brand<number, 'EUR'>
+
+function makeUSD(amount: number): USD {
+  return amount as USD
+}
+
+function makeEUR(amount: number): EUR {
+  return amount as EUR
+}
+
+let usd = makeUSD(100)
+let eur = makeEUR(100)
+
+// usd = eur // Error: different brands
+```
+
+## Best Practices
+
+1. **Prefer type inference** - Let TypeScript infer types when obvious
+2. **Use strict null checks** - Enable strictNullChecks for better safety
+3. **Avoid `any`** - Use `unknown` and narrow with type guards
+4. **Use discriminated unions** - Better than loose unions for state
+5. **Leverage const assertions** - Get narrow literal types
+6. **Use branded types** - When structural typing isn't enough
+7. **Document complex types** - Add JSDoc comments
+8. **Extract reusable types** - DRY principle applies to types too
+9. **Use utility types** - Leverage built-in transformation types
+10. **Test your types** - Use type assertions to verify type correctness

+# TypeScript Utility Types Reference
+
+TypeScript provides several built-in utility types that help transform and manipulate types. These are implemented using advanced type features like mapped types and conditional types.
+
+## Property Modifiers
+
+### Partial\<T\>
+
+Makes all properties in `T` optional.
+
+```typescript
+interface User {
+  id: string
+  name: string
+  email: string
+  age: number
+}
+
+type PartialUser = Partial<User>
+// {
+//   id?: string
+//   name?: string
+//   email?: string
+//   age?: number
+// }
+
+// Useful for update operations
+function updateUser(id: string, updates: Partial<User>) {
+  // Only update provided fields
+}
+
+updateUser('123', { name: 'Alice' }) // OK
+updateUser('123', { name: 'Alice', age: 30 }) // OK
+```
+
+### Required\<T\>
+
+Makes all properties in `T` required (removes optionality).
+
+```typescript
+interface Config {
+  host?: string
+  port?: number
+  timeout?: number
+}
+
+type RequiredConfig = Required<Config>
+// {
+//   host: string
+//   port: number
+//   timeout: number
+// }
+
+function initServer(config: RequiredConfig) {
+  // All properties are guaranteed to exist
+  console.log(config.host, config.port, config.timeout)
+}
+```
+
+### Readonly\<T\>
+
+Makes all properties in `T` readonly.
+
+```typescript
+interface MutablePoint {
+  x: number
+  y: number
+}
+
+type ImmutablePoint = Readonly<MutablePoint>
+// {
+//   readonly x: number
+//   readonly y: number
+// }
+
+const point: ImmutablePoint = { x: 0, y: 0 }
+// point.x = 10 // Error: Cannot assign to 'x' because it is a read-only property
+```
+
+### Mutable\<T\> (Custom)
+
+Removes readonly modifiers (not built-in, but useful pattern).
+
+```typescript
+type Mutable<T> = {
+  -readonly [K in keyof T]: T[K]
+}
+
+interface ReadonlyPerson {
+  readonly name: string
+  readonly age: number
+}
+
+type MutablePerson = Mutable<ReadonlyPerson>
+// {
+//   name: string
+//   age: number
+// }
+```
+
+## Property Selection
+
+### Pick\<T, K\>
+
+Creates a type by picking specific properties from `T`.
+
+```typescript
+interface User {
+  id: string
+  name: string
+  email: string
+  password: string
+  createdAt: Date
+}
+
+type UserProfile = Pick<User, 'id' | 'name' | 'email'>
+// {
+//   id: string
+//   name: string
+//   email: string
+// }
+
+// Useful for API responses
+function getUserProfile(id: string): UserProfile {
+  // Return only safe properties
+}
+```
+
+### Omit\<T, K\>
+
+Creates a type by omitting specific properties from `T`.
+
+```typescript
+interface User {
+  id: string
+  name: string
+  email: string
+  password: string
+}
+
+type UserWithoutPassword = Omit<User, 'password'>
+// {
+//   id: string
+//   name: string
+//   email: string
+// }
+
+// Useful for public user data
+function publishUser(user: User): UserWithoutPassword {
+  const { password, ...publicData } = user
+  return publicData
+}
+```
+
+## Union Type Utilities
+
+### Exclude\<T, U\>
+
+Excludes types from `T` that are assignable to `U`.
+
+```typescript
+type T1 = Exclude<'a' | 'b' | 'c', 'a'> // "b" | "c"
+type T2 = Exclude<string | number | boolean, boolean> // string | number
+
+type EventType = 'click' | 'scroll' | 'mousemove' | 'keypress'
+type UIEvent = Exclude<EventType, 'scroll'> // "click" | "mousemove" | "keypress"
+```
+
+### Extract\<T, U\>
+
+Extracts types from `T` that are assignable to `U`.
+
+```typescript
+type T1 = Extract<'a' | 'b' | 'c', 'a' | 'f'> // "a"
+type T2 = Extract<string | number | boolean, boolean> // boolean
+
+type Shape = 'circle' | 'square' | 'triangle' | 'rectangle'
+type RoundedShape = Extract<Shape, 'circle'> // "circle"
+```
+
+### NonNullable\<T\>
+
+Excludes `null` and `undefined` from `T`.
+
+```typescript
+type T1 = NonNullable<string | null | undefined> // string
+type T2 = NonNullable<string | number | null> // string | number
+
+function processValue(value: string | null | undefined) {
+  if (value !== null && value !== undefined) {
+    const nonNull: NonNullable<typeof value> = value
+    // nonNull is guaranteed to be string
+  }
+}
+```
+
+## Object Construction
+
+### Record\<K, T\>
+
+Constructs an object type with keys of type `K` and values of type `T`.
+
+```typescript
+type PageInfo = Record<string, number>
+// { [key: string]: number }
+
+const pages: PageInfo = {
+  home: 1,
+  about: 2,
+  contact: 3,
+}
+
+// Useful for mapped objects
+type UserRole = 'admin' | 'user' | 'guest'
+type RolePermissions = Record<UserRole, string[]>
+
+const permissions: RolePermissions = {
+  admin: ['read', 'write', 'delete'],
+  user: ['read', 'write'],
+  guest: ['read'],
+}
+
+// With specific keys
+type ThemeColors = Record<'primary' | 'secondary' | 'accent', string>
+
+const colors: ThemeColors = {
+  primary: '#007bff',
+  secondary: '#6c757d',
+  accent: '#28a745',
+}
+```
+
+## Function Utilities
+
+### Parameters\<T\>
+
+Extracts the parameter types of a function type as a tuple.
+
+```typescript
+function createUser(name: string, age: number, email: string) {
+  // ...
+}
+
+type CreateUserParams = Parameters<typeof createUser>
+// [name: string, age: number, email: string]
+
+// Useful for higher-order functions
+function withLogging<T extends (...args: any[]) => any>(
+  fn: T,
+  ...args: Parameters<T>
+): ReturnType<T> {
+  console.log('Calling with:', args)
+  return fn(...args)
+}
+```
+
+### ConstructorParameters\<T\>
+
+Extracts the parameter types of a constructor function type.
+
+```typescript
+class User {
+  constructor(public name: string, public age: number) {}
+}
+
+type UserConstructorParams = ConstructorParameters<typeof User>
+// [name: string, age: number]
+
+function createUser(...args: UserConstructorParams): User {
+  return new User(...args)
+}
+```
+
+### ReturnType\<T\>
+
+Extracts the return type of a function type.
+

+function createUser() {
+  return {
+    id: '123',
+    name: 'Alice',
+    email: 'alice@example.com',
+  }
+}
+
+type User = ReturnType<typeof createUser>
+// {
+//   id: string
+//   name: string
+//   email: string
+// }
+
+// Useful with async functions
+async function fetchData() {
+  return { success: true, data: [1, 2, 3] }
+}
+
+type FetchResult = ReturnType<typeof fetchData>
+// Promise<{ success: boolean; data: number[] }>
+
+type UnwrappedResult = Awaited<FetchResult>
+// { success: boolean; data: number[] }
+```
+
+### InstanceType\<T\>
+
+Extracts the instance type of a constructor function type.
+
+```typescript
+class User {
+  name: string
+  constructor(name: string) {
+    this.name = name
+  }
+}
+
+type UserInstance = InstanceType<typeof User>
+// User
+
+function processUser(user: UserInstance) {
+  console.log(user.name)
+}
+```
+
+### ThisParameterType\<T\>
+
+Extracts the type of the `this` parameter for a function type.
+
+```typescript
+function toHex(this: Number) {
+  return this.toString(16)
+}
+
+type ThisType = ThisParameterType<typeof toHex> // Number
+```
+
+### OmitThisParameter\<T\>
+
+Removes the `this` parameter from a function type.
+
+```typescript
+function toHex(this: Number) {
+  return this.toString(16)
+}
+
+type PlainFunction = OmitThisParameter<typeof toHex>
+// () => string
+```
+
+## String Manipulation
+
+### Uppercase\<S\>
+
+Converts string literal type to uppercase.
+
+```typescript
+type Greeting = 'hello'
+type LoudGreeting = Uppercase<Greeting> // "HELLO"
+
+// Useful for constants
+type HttpMethod = 'get' | 'post' | 'put' | 'delete'
+type HttpMethodUppercase = Uppercase<HttpMethod>
+// "GET" | "POST" | "PUT" | "DELETE"
+```
+
+### Lowercase\<S\>
+
+Converts string literal type to lowercase.
+
+```typescript
+type Greeting = 'HELLO'
+type QuietGreeting = Lowercase<Greeting> // "hello"
+```
+
+### Capitalize\<S\>
+
+Capitalizes the first letter of a string literal type.
+
+```typescript
+type Event = 'click' | 'scroll' | 'mousemove'
+type EventHandler = `on${Capitalize<Event>}`
+// "onClick" | "onScroll" | "onMousemove"
+```
+
+### Uncapitalize\<S\>
+
+Uncapitalizes the first letter of a string literal type.
+
+```typescript
+type Greeting = 'Hello'
+type LowerGreeting = Uncapitalize<Greeting> // "hello"
+```
+
+## Async Utilities
+
+### Awaited\<T\>
+
+Unwraps the type of a Promise (recursively).
+
+```typescript
+type T1 = Awaited<Promise<string>> // string
+type T2 = Awaited<Promise<Promise<number>>> // number
+type T3 = Awaited<boolean | Promise<string>> // boolean | string
+
+// Useful with async functions
+async function fetchUser() {
+  return { id: '123', name: 'Alice' }
+}
+
+type User = Awaited<ReturnType<typeof fetchUser>>
+// { id: string; name: string }
+```
+
+## Custom Utility Types
+
+### DeepPartial\<T\>
+
+Makes all properties and nested properties optional.
+
+```typescript
+type DeepPartial<T> = {
+  [K in keyof T]?: T[K] extends object ? DeepPartial<T[K]> : T[K]
+}
+
+interface User {
+  id: string
+  profile: {
+    name: string
+    address: {
+      street: string
+      city: string
+    }
+  }
+}
+
+type PartialUser = DeepPartial<User>
+// All properties at all levels are optional
+```
+
+### DeepReadonly\<T\>
+
+Makes all properties and nested properties readonly.
+
+```typescript
+type DeepReadonly<T> = {
+  readonly [K in keyof T]: T[K] extends object ? DeepReadonly<T[K]> : T[K]
+}
+
+interface User {
+  id: string
+  profile: {
+    name: string
+    address: {
+      street: string
+      city: string
+    }
+  }
+}
+
+type ImmutableUser = DeepReadonly<User>
+// All properties at all levels are readonly
+```
+
+### PartialBy\<T, K\>
+
+Makes specific properties optional.
+
+```typescript
+type PartialBy<T, K extends keyof T> = Omit<T, K> & Partial<Pick<T, K>>
+
+interface User {
+  id: string
+  name: string
+  email: string
+  age: number
+}
+
+type UserWithOptionalEmail = PartialBy<User, 'email' | 'age'>
+// {
+//   id: string
+//   name: string
+//   email?: string
+//   age?: number
+// }
+```
+
+### RequiredBy\<T, K\>
+
+Makes specific properties required.
+
+```typescript
+type RequiredBy<T, K extends keyof T> = Omit<T, K> & Required<Pick<T, K>>
+
+interface User {
+  id?: string
+  name?: string
+  email?: string
+}
+
+type UserWithRequiredId = RequiredBy<User, 'id'>
+// {
+//   id: string
+//   name?: string
+//   email?: string
+// }
+```
+
+### PickByType\<T, U\>
+
+Picks properties by their value type.
+
+```typescript
+type PickByType<T, U> = {
+  [K in keyof T as T[K] extends U ? K : never]: T[K]
+}
+
+interface User {
+  id: string
+  name: string
+  age: number
+  active: boolean
+}
+
+type StringProperties = PickByType<User, string>
+// { id: string; name: string }
+
+type NumberProperties = PickByType<User, number>
+// { age: number }
+```
+
+### OmitByType\<T, U\>
+
+Omits properties by their value type.
+
+```typescript
+type OmitByType<T, U> = {
+  [K in keyof T as T[K] extends U ? never : K]: T[K]
+}
+
+interface User {
+  id: string
+  name: string
+  age: number
+  active: boolean
+}
+
+type NonStringProperties = OmitByType<User, string>
+// { age: number; active: boolean }
+```
+
+### Prettify\<T\>
+
+Flattens intersections for better IDE tooltips.
+
+```typescript
+type Prettify<T> = {
+  [K in keyof T]: T[K]
+} & {}
+
+type A = { a: string }
+type B = { b: number }
+type C = A & B
+
+type PrettyC = Prettify<C>
+// Displays as: { a: string; b: number }
+// Instead of: A & B
+```
+
+### ValueOf\<T\>
+
+Gets the union of all value types.
+
+```typescript
+type ValueOf<T> = T[keyof T]
+
+interface Colors {
+  red: '#ff0000'
+  green: '#00ff00'
+  blue: '#0000ff'
+}
+
+type ColorValue = ValueOf<Colors>
+// "#ff0000" | "#00ff00" | "#0000ff"
+```
+
+### Nullable\<T\>
+
+Makes type nullable.
+
+```typescript
+type Nullable<T> = T | null
+
+type NullableString = Nullable<string> // string | null
+```
+
+### Maybe\<T\>
+
+Makes type nullable or undefined.
+
+```typescript
+type Maybe<T> = T | null | undefined
+
+type MaybeString = Maybe<string> // string | null | undefined
+```
+
+### UnionToIntersection\<U\>
+
+Converts union to intersection (advanced).
+
+```typescript
+type UnionToIntersection<U> = (U extends any ? (k: U) => void : never) extends (
+  k: infer I,
+) => void
+  ? I
+  : never
+
+type Union = { a: string } | { b: number }
+type Intersection = UnionToIntersection<Union>
+// { a: string } & { b: number }
+```
+
+## Combining Utility Types
+
+Utility types can be composed for powerful transformations:
+
+```typescript
+// Make specific properties optional and readonly
+type PartialReadonly<T, K extends keyof T> = Readonly<Pick<T, K>> &
+  Partial<Omit<T, K>>
+
+interface User {
+  id: string
+  name: string
+  email: string
+  password: string
+}
+
+type SafeUser = PartialReadonly<User, 'id' | 'name'>
+// {
+//   readonly id: string
+//   readonly name: string
+//   email?: string
+//   password?: string
+// }
+
+// Pick and make readonly
+type ReadonlyPick<T, K extends keyof T> = Readonly<Pick<T, K>>
+
+// Omit and make required
+type RequiredOmit<T, K extends keyof T> = Required<Omit<T, K>>
+```
+
+## Best Practices
+
+1. **Use built-in utilities first** - They're well-tested and optimized
+2. **Compose utilities** - Combine utilities for complex transformations
+3. **Create custom utilities** - For patterns you use frequently
+4. **Name utilities clearly** - Make intent obvious from the name
+5. **Document complex utilities** - Add JSDoc for non-obvious transformations
+6. **Test utility types** - Use type assertions to verify behavior
+7. **Avoid over-engineering** - Don't create utilities for one-off uses
+8. **Consider readability** - Sometimes explicit types are clearer
+9. **Use Prettify** - For better IDE tooltips with intersections
+10. **Leverage keyof** - For type-safe property selection

+# Gitea Actions Setup
+
+This directory contains workflows for Gitea Actions, which is a self-hosted CI/CD system compatible with GitHub Actions syntax.
+
+## Workflow: go.yml
+
+The `go.yml` workflow handles building, testing, and releasing the ORLY relay when version tags are pushed.
+
+### Features
+
+- **No external dependencies**: Uses only inline shell commands (no actions from GitHub)
+- **Pure Go builds**: Uses CGO_ENABLED=0 with purego for secp256k1
+- **Automated releases**: Creates Gitea releases with binaries and checksums
+- **Tests included**: Runs the full test suite before building releases
+
+### Prerequisites
+
+1. **Gitea Token**: Add a secret named `GITEA_TOKEN` in your repository settings
+   - Go to: Repository Settings → Secrets → Add Secret
+   - Name: `GITEA_TOKEN`
+   - Value: Your Gitea personal access token with `repo` and `write:packages` permissions
+
+2. **Runner Configuration**: Ensure your Gitea Actions runner is properly configured
+   - The runner should have access to pull Docker images
+   - Ubuntu-latest image should be available
+
+### Usage
+
+To create a new release:
+
+```bash
+# 1. Update version in pkg/version/version file
+echo "v0.29.4" > pkg/version/version
+
+# 2. Commit the version change
+git add pkg/version/version
+git commit -m "bump to v0.29.4"
+
+# 3. Create and push the tag
+git tag v0.29.4
+git push origin v0.29.4
+
+# 4. The workflow will automatically:
+#    - Build the binary
+#    - Run tests
+#    - Create a release on your Gitea instance
+#    - Upload the binary and checksums
+```
+
+### Environment Variables
+
+The workflow uses standard Gitea Actions environment variables:
+
+- `GITHUB_WORKSPACE`: Working directory for the job
+- `GITHUB_REF_NAME`: Tag name (e.g., v1.2.3)
+- `GITHUB_REPOSITORY`: Repository in format `owner/repo`
+- `GITHUB_SERVER_URL`: Your Gitea instance URL (e.g., https://git.nostrdev.com)
+
+### Troubleshooting
+
+**Issue**: Workflow fails to clone repository
+- **Solution**: Check that the repository is accessible without authentication, or configure runner credentials
+
+**Issue**: Cannot create release
+- **Solution**: Verify `GITEA_TOKEN` secret is set correctly with appropriate permissions
+
+**Issue**: Go version not found
+- **Solution**: The workflow downloads Go 1.25.0 directly from go.dev, ensure the runner has internet access
+
+### Customization
+
+To modify the workflow:
+
+1. Edit `.gitea/workflows/go.yml`
+2. Test changes by pushing a tag (or use `act` locally for testing)
+3. Monitor the Actions tab in your Gitea repository for results
+
+## Differences from GitHub Actions
+
+- **Action dependencies**: This workflow doesn't use external actions (like `actions/checkout@v4`) to avoid GitHub dependency
+- **Release creation**: Uses `tea` CLI instead of GitHub's release action
+- **Inline commands**: All setup and build steps are done with shell scripts
+
+This makes the workflow completely self-contained and independent of external services.

+# Badger Database Migration Guide
+
+## Overview
+
+This guide covers migrating your ORLY relay database when changing Badger configuration parameters, specifically for the VLogPercentile and table size optimizations.
+
+## When Migration is Needed
+
+Based on research of Badger v4 source code and documentation:
+
+### Configuration Changes That DON'T Require Migration
+
+The following options can be changed **without migration**:
+- `BlockCacheSize` - Only affects in-memory cache
+- `IndexCacheSize` - Only affects in-memory cache
+- `NumCompactors` - Runtime setting
+- `NumLevelZeroTables` - Affects compaction timing
+- `NumMemtables` - Affects write buffering
+- `DetectConflicts` - Runtime conflict detection
+- `Compression` - New data uses new compression, old data remains as-is
+- `BlockSize` - Explicitly stated in Badger source: "Changing BlockSize across DB runs will not break badger"
+
+### Configuration Changes That BENEFIT from Migration
+
+The following options apply to **new writes only** - existing data gradually adopts new settings through compaction:
+- `VLogPercentile` - Affects where **new** values are stored (LSM vs vlog)
+- `BaseTableSize` - **New** SST files use new size
+- `MemTableSize` - Affects new write buffering
+- `BaseLevelSize` - Affects new LSM tree structure
+- `ValueLogFileSize` - New vlog files use new size
+
+**Migration Impact:** Without migration, existing data remains in its current location (LSM tree or value log). The database will **gradually** adapt through normal compaction, which may take days or weeks depending on write volume.
+
+## Migration Options
+
+### Option 1: No Migration (Let Natural Compaction Handle It)
+
+**Best for:** Low-traffic relays, testing environments
+
+**Pros:**
+- No downtime required
+- No manual intervention
+- Zero risk of data loss
+
+**Cons:**
+- Benefits take time to materialize (days/weeks)
+- Old data layout persists until natural compaction
+- Cache tuning benefits delayed
+
+**Steps:**
+1. Update Badger configuration in `pkg/database/database.go`
+2. Restart ORLY relay
+3. Monitor performance over several days
+4. Optionally run manual GC: `db.RunValueLogGC(0.5)` periodically
+
+### Option 2: Manual Value Log Garbage Collection
+
+**Best for:** Medium-traffic relays wanting faster optimization
+
+**Pros:**
+- Faster than natural compaction
+- Still safe (no export/import)
+- Can run while relay is online
+
+**Cons:**
+- Still gradual (hours instead of days)
+- CPU/disk intensive during GC
+- Partial benefit until GC completes
+
+**Steps:**
+1. Update Badger configuration
+2. Restart ORLY relay
+3. Monitor logs for compaction activity
+4. Manually trigger GC if needed (future feature - not currently exposed)
+
+### Option 3: Full Export/Import Migration (RECOMMENDED for Production)
+
+**Best for:** Production relays, large databases, maximum performance
+
+**Pros:**
+- Immediate full benefit of new configuration
+- Clean database structure
+- Predictable migration time
+- Reclaims all disk space
+
+**Cons:**
+- Requires relay downtime (several hours for large DBs)
+- Requires 2x disk space temporarily
+- More complex procedure
+
+**Steps:** See detailed procedure below
+
+## Full Migration Procedure (Option 3)
+
+### Prerequisites
+
+1. **Disk space:** At minimum 2.5x current database size
+   - 1x for current database
+   - 1x for JSONL export
+   - 0.5x for new database (will be smaller with compression)
+
+2. **Time estimate:**
+   - Export: ~100-500 MB/s depending on disk speed
+   - Import: ~50-200 MB/s with indexing overhead
+   - Example: 10 GB database = ~10-30 minutes total
+
+3. **Backup:** Ensure you have a recent backup before proceeding
+
+### Step-by-Step Migration
+
+#### 1. Prepare Migration Script
+
+Use the provided `scripts/migrate-badger-config.sh` script (see below).
+
+#### 2. Stop the Relay
+
+```bash
+# If using systemd
+sudo systemctl stop orly
+
+# If running manually
+pkill orly
+```
+
+#### 3. Run Migration
+
+```bash
+cd ~/src/next.orly.dev
+chmod +x scripts/migrate-badger-config.sh
+./scripts/migrate-badger-config.sh
+```
+
+The script will:
+- Export all events to JSONL format
+- Move old database to backup location
+- Create new database with updated configuration
+- Import all events (rebuilds indexes automatically)
+- Verify event count matches
+
+#### 4. Verify Migration
+
+```bash
+# Check that events were migrated
+echo "Old event count:"
+cat ~/.local/share/ORLY-backup-*/migration.log | grep "exported.*events"
+
+echo "New event count:"
+cat ~/.local/share/ORLY/migration.log | grep "saved.*events"
+```
+
+#### 5. Restart Relay
+
+```bash
+# If using systemd
+sudo systemctl start orly
+sudo journalctl -u orly -f
+
+# If running manually
+./orly
+```
+
+#### 6. Monitor Performance
+
+Watch for improvements in:
+- Cache hit ratio (should be >85% with new config)
+- Average query latency (should be <3ms for cached events)
+- No "Block cache too small" warnings in logs
+
+#### 7. Clean Up (After Verification)
+
+```bash
+# Once you confirm everything works (wait 24-48 hours)
+rm -rf ~/.local/share/ORLY-backup-*
+rm ~/.local/share/ORLY/events-export.jsonl
+```
+
+## Migration Script
+
+The migration script is located at `scripts/migrate-badger-config.sh` and handles:
+- Automatic export of all events to JSONL
+- Safe backup of existing database
+- Creation of new database with updated config
+- Import and indexing of all events
+- Verification of event counts
+
+## Rollback Procedure
+
+If migration fails or performance degrades:
+
+```bash
+# Stop the relay
+sudo systemctl stop orly  # or pkill orly
+
+# Restore old database
+rm -rf ~/.local/share/ORLY
+mv ~/.local/share/ORLY-backup-$(date +%Y%m%d)* ~/.local/share/ORLY
+
+# Restart with old configuration
+sudo systemctl start orly
+```
+
+## Configuration Changes Summary
+
+### Changes Applied in pkg/database/database.go
+
+```go
+// Cache sizes (can change without migration)
+opts.BlockCacheSize = 16384 MB  (was 512 MB)
+opts.IndexCacheSize = 4096 MB   (was 256 MB)
+
+// Table sizes (benefits from migration)
+opts.BaseTableSize = 8 MB       (was 64 MB)
+opts.MemTableSize = 16 MB       (was 64 MB)
+opts.ValueLogFileSize = 128 MB  (was 256 MB)
+
+// Inline event optimization (CRITICAL - benefits from migration)
+opts.VLogPercentile = 0.99      (was 0.0 - default)
+
+// LSM structure (benefits from migration)
+opts.BaseLevelSize = 64 MB      (was 10 MB - default)
+
+// Performance settings (no migration needed)
+opts.DetectConflicts = false    (was true)
+opts.Compression = options.ZSTD (was options.None)
+opts.NumCompactors = 8          (was 4)
+opts.NumMemtables = 8           (was 5)
+```
+
+## Expected Improvements
+
+### Before Migration
+- Cache hit ratio: 33%
+- Average latency: 9.35ms
+- P95 latency: 34.48ms
+- Block cache warnings: Yes
+
+### After Migration
+- Cache hit ratio: 85-95%
+- Average latency: <3ms
+- P95 latency: <8ms
+- Block cache warnings: No
+- Inline events: 3-5x faster reads
+
+## Troubleshooting
+
+### Migration Script Fails
+
+**Error:** "Not enough disk space"
+- Free up space or use Option 1 (natural compaction)
+- Ensure you have 2.5x current DB size available
+
+**Error:** "Export failed"
+- Check database is not corrupted
+- Ensure ORLY is stopped
+- Check file permissions
+
+**Error:** "Import count mismatch"
+- This is informational - some events may be duplicates
+- Check logs for specific errors
+- Verify core events are present via relay queries
+
+### Performance Not Improved
+
+**After migration, performance is the same:**
+1. Verify configuration was actually applied:
+   ```bash
+   # Check running relay logs for config output
+   sudo journalctl -u orly | grep -i "block.*cache\|vlog"
+   ```
+
+2. Wait for cache to warm up (2-5 minutes after start)
+
+3. Check if workload changed (different query patterns)
+
+4. Verify disk I/O is not bottleneck:
+   ```bash
+   iostat -x 5
+   ```
+
+### High CPU During Migration
+
+- This is normal - import rebuilds all indexes
+- Migration is single-threaded by design (data consistency)
+- Expect 30-60% CPU usage on one core
+
+## Additional Notes
+
+### Compression Impact
+
+The `Compression = options.ZSTD` setting:
+- Only compresses **new** data
+- Old data remains uncompressed until rewritten by compaction
+- Migration forces all data to be rewritten → immediate compression benefit
+- Expect 2-3x compression ratio for event data
+
+### VLogPercentile Behavior
+
+With `VLogPercentile = 0.99`:
+- **99% of values** stored in LSM tree (fast access)
+- **1% of values** stored in value log (large events >100 KB)
+- Threshold dynamically adjusted based on value size distribution
+- Perfect for ORLY's inline event optimization
+
+### Production Considerations
+
+For production relays:
+1. Schedule migration during low-traffic period
+2. Notify users of maintenance window
+3. Have rollback plan ready
+4. Monitor closely for 24-48 hours after migration
+5. Keep backup for at least 1 week

+- The p8k crypto library uses `github.com/ebitengine/purego` to dynamically load `libsecp256k1.so` at runtime
+- This avoids CGO complexity while maintaining C library performance
+- `libsecp256k1.so` must be in `LD_LIBRARY_PATH` or same directory as binary
+
+**Database Backend Selection:**
+- Supports multiple backends via `ORLY_DB_TYPE` environment variable
+- **Badger** (default): Embedded key-value store with custom indexing, ideal for single-instance deployments
+- **DGraph**: Distributed graph database for larger, multi-node deployments
+- Backend selected via factory pattern in `pkg/database/factory.go`
+- All backends implement the same `Database` interface defined in `pkg/database/interface.go`
+
+**Database Query Pattern:**
+- Filters are analyzed in `get-indexes-from-filter.go` to determine optimal query strategy
+- Filters are normalized before cache lookup, ensuring identical queries with different field ordering hit the cache
+- Different query builders (`query-for-kinds.go`, `query-for-authors.go`, etc.) handle specific filter patterns
+- All queries return event serials (uint64) for efficient joining
+- Query results cached with zstd level 9 compression (configurable size and TTL)
+- Final events fetched via `fetch-events-by-serials.go`
+
+**WebSocket Message Flow:**
+1. `handle-websocket.go` accepts connection and spawns goroutine
+2. Incoming frames parsed by `pkg/protocol/ws/`
+3. Routed to handlers: `handle-event.go`, `handle-req.go`, `handle-count.go`, etc.
+4. Events stored via `database.SaveEvent()`
+5. Active subscriptions notified via `publishers.Publish()`
+
+**Configuration System:**
+- Uses `go-simpler.org/env` for struct tags
+- All config in `app/config/config.go` with `ORLY_` prefix
+- Supports XDG directories via `github.com/adrg/xdg`
+- Default data directory: `~/.local/share/ORLY`
+
+**Event Publishing:**
+- `pkg/protocol/publish/` manages publisher registry
+- Each WebSocket connection registers its subscriptions
+- `publishers.Publish(event)` broadcasts to matching subscribers
+- Efficient filter matching without re-querying database
+
+**Embedded Assets:**
+- Web UI built to `app/web/dist/`
+- Embedded via `//go:embed` directive in `app/web.go`
+- Served at root path `/` with API at `/api/*`
+
+## Development Workflow
+
+### Making Changes to Web UI
+1. Edit files in `app/web/src/`
+2. For hot reload: `cd app/web && bun run dev` (with `ORLY_WEB_DISABLE=true` and `ORLY_WEB_DEV_PROXY_URL=http://localhost:5173`)
+3. For production build: `./scripts/update-embedded-web.sh`
+
+### Adding New Nostr Protocol Handlers
+1. Create `app/handle-<message-type>.go`
+2. Add case in `app/handle-message.go` message router
+3. Implement handler following existing patterns
+4. Add tests in `app/<handler>_test.go`
+
+### Adding Database Indexes
+1. Define index in `pkg/database/indexes/`
+2. Add migration in `pkg/database/migrations.go`
+3. Update `save-event.go` to populate index
+4. Add query builder in `pkg/database/query-for-<index>.go`
+5. Update `get-indexes-from-filter.go` to use new index
+
+### Environment Variables for Development
+```bash
+# Verbose logging
+export ORLY_LOG_LEVEL=trace
+export ORLY_DB_LOG_LEVEL=debug
+
+# Enable profiling
+export ORLY_PPROF=cpu
+export ORLY_PPROF_HTTP=true  # Serves on :6060

+```
+
+## Key Dependencies
+
+- `github.com/dgraph-io/badger/v4` - Embedded database
+- `github.com/gorilla/websocket` - WebSocket server
+- `github.com/minio/sha256-simd` - SIMD SHA256
+- `github.com/templexxx/xhex` - SIMD hex encoding
+- `github.com/ebitengine/purego` - CGO-free C library loading
+- `go-simpler.org/env` - Environment variable configuration
+- `lol.mleku.dev` - Custom logging library
+
+## Testing Guidelines
+
+- Test files use `_test.go` suffix
+- Use `github.com/stretchr/testify` for assertions
+- Database tests require temporary database setup (see `pkg/database/testmain_test.go`)
+- WebSocket tests should use `relay-tester` package
+- Always clean up resources in tests (database, connections, goroutines)
+
+## Performance Considerations
+
+- **Query Cache**: 512MB query result cache (configurable via `ORLY_QUERY_CACHE_SIZE_MB`) with zstd level 9 compression reduces database load for repeated queries
+- **Filter Normalization**: Filters are normalized before cache lookup, so identical queries with different field ordering produce cache hits
+- **Database Caching**: Tune `ORLY_DB_BLOCK_CACHE_MB` and `ORLY_DB_INDEX_CACHE_MB` for workload (Badger backend only)
+- **Query Optimization**: Add indexes for common filter patterns; multiple specialized query builders optimize different filter combinations
+- **Batch Operations**: ID lookups and event fetching use batch operations via `GetSerialsByIds` and `FetchEventsBySerials`
+- **Memory Pooling**: Use buffer pools in encoders (see `pkg/encoders/event/`)
+- **SIMD Operations**: Leverage minio/sha256-simd and templexxx/xhex for cryptographic operations
+- **Goroutine Management**: Each WebSocket connection runs in its own goroutine
+
+## Recent Optimizations
+
+ORLY has received several significant performance improvements in recent updates:
+
+### Query Cache System (Latest)
+- 512MB query result cache with zstd level 9 compression
+- Filter normalization ensures cache hits regardless of filter field ordering
+- Configurable size (`ORLY_QUERY_CACHE_SIZE_MB`) and TTL (`ORLY_QUERY_CACHE_MAX_AGE`)
+- Dramatically reduces database load for repeated queries (common in Nostr clients)
+- Cache key includes normalized filter representation for optimal hit rate
+
+### Badger Cache Tuning
+- Optimized block cache (default 512MB, tune via `ORLY_DB_BLOCK_CACHE_MB`)
+- Optimized index cache (default 256MB, tune via `ORLY_DB_INDEX_CACHE_MB`)
+- Resulted in 10-15% improvement in most benchmark scenarios
+- See git history for cache tuning evolution
+
+### Query Execution Improvements
+- Multiple specialized query builders for different filter patterns:
+  - `query-for-kinds.go` - Kind-based queries
+  - `query-for-authors.go` - Author-based queries
+  - `query-for-tags.go` - Tag-based queries
+  - Combination builders for `kinds+authors`, `kinds+tags`, `kinds+authors+tags`
+- Batch operations for ID lookups via `GetSerialsByIds`
+- Serial-based event fetching for efficiency
+- Filter analysis in `get-indexes-from-filter.go` selects optimal strategy
+

+go get google.golang.org/grpc@latest
+go get github.com/dgraph-io/badger/v4  # For metadata storage
+```
+
+All dependencies have been added and `go mod tidy` completed successfully.
+
+### 🔌 Dgraph Server Integration Details
+
+The implementation uses a **client-server architecture**:
+
+1. **Dgraph Server** (External)
+   - Runs as a separate process (via docker or standalone)
+   - Default gRPC endpoint: `localhost:9080`
+   - Configured via `ORLY_DGRAPH_URL` environment variable
+
+2. **ORLY Dgraph Client** (Integrated)
+   - Uses dgo library for gRPC communication
+   - Connects on startup, applies Nostr schema automatically
+   - Query and Mutate methods communicate with dgraph server
+
+3. **Dual Storage Architecture**
+   - **Dgraph**: Event graph storage (events, authors, tags, relationships)
+   - **Badger**: Metadata storage (markers, counters, relay identity)
+   - This hybrid approach leverages strengths of both databases
+
+## Implementation Approach
+
+### Marker-Based Storage
+
+For metadata that doesn't fit the graph model (subscriptions, NIP-43, identity), we use a marker-based approach:
+
+1. **Markers** are special graph nodes with type "Marker"
+2. Each marker has:
+   - `marker.key`: String index for lookup
+   - `marker.value`: Hex-encoded or JSON-encoded data
+3. This provides key-value storage within the graph database
+
+### Serial Number Management
+
+Serial numbers are critical for event ordering. Implementation:
+
+```go
+// Serial counter stored as a special marker
+const serialCounterKey = "serial_counter"
+
+// Atomic increment with mutex protection
+func (d *D) getNextSerial() (uint64, error) {
+    serialMutex.Lock()
+    defer serialMutex.Unlock()
+
+    // Query current value, increment, save
+    ...
+}
+```
+
+### Event Storage
+
+Events are stored as graph nodes with relationships:
+
+- **Event nodes**: ID, serial, kind, created_at, content, sig, pubkey, tags
+- **Author nodes**: Pubkey with reverse edges to events
+- **Tag nodes**: Tag type and value with reverse edges
+- **Relationships**: `authored_by`, `references`, `mentions`, `tagged_with`
+
+## Files Created/Modified
+
+### New Files (`pkg/dgraph/`)
+- `dgraph.go`: Main implementation, initialization, schema
+- `save-event.go`: Event storage with RDF triple generation
+- `query-events.go`: Nostr filter to DQL translation
+- `fetch-event.go`: Event retrieval methods
+- `delete.go`: Event deletion
+- `markers.go`: Key-value metadata storage
+- `identity.go`: Relay identity management
+- `serial.go`: Serial number generation

+- `README.md`: Documentation
+
+### Modified Files

+- `app/server.go`: Changed to use Database interface
+- `app/main.go`: Updated to use Database interface
+- `main.go`: Added dgraph import and factory usage
+
+## Usage
+
+### Setting Up Dgraph Server
+
+Before using dgraph mode, start a dgraph server:
+
+```bash
+# Using docker (recommended)
+docker run -d -p 8080:8080 -p 9080:9080 -p 8000:8000 \
+  -v ~/dgraph:/dgraph \
+  dgraph/standalone:latest
+
+# Or using docker-compose (see docs/dgraph-docker-compose.yml)
+docker-compose up -d dgraph
+```
+
+### Environment Configuration
+
+```bash
+# Use Badger (default)
+./orly
+
+# Use Dgraph with default localhost connection
+export ORLY_DB_TYPE=dgraph
+./orly
+
+# Use Dgraph with custom server
+export ORLY_DB_TYPE=dgraph
+export ORLY_DGRAPH_URL=remote.dgraph.server:9080
+./orly
+
+# With full configuration
+export ORLY_DB_TYPE=dgraph
+export ORLY_DGRAPH_URL=localhost:9080
+export ORLY_DATA_DIR=/path/to/data
+./orly
+```
+
+### Data Storage
+
+#### Badger
+- Single directory with SST files
+- Typical size: 100-500MB for moderate usage
+
+#### Dgraph
+- Three subdirectories:
+  - `p/`: Postings (main data)
+  - `w/`: Write-ahead log
+  - Typical size: 500MB-2GB overhead + event data
+
+## Performance Considerations
+
+### Memory Usage
+- **Badger**: ~100-200MB baseline
+- **Dgraph**: ~500MB-1GB baseline
+
+### Query Performance
+- **Simple queries** (by ID, kind, author): Dgraph may be slower than Badger
+- **Graph traversals** (follows-of-follows): Dgraph significantly faster
+- **Full-text search**: Dgraph has built-in support
+
+### Recommendations
+1. Use Badger for simple, high-performance relays
+2. Use Dgraph for relays needing complex graph queries
+3. Consider hybrid approach: Badger primary + Dgraph secondary
+
+## Next Steps to Complete
+
+### ✅ STEP 1: Dgraph Server Integration (COMPLETED)
+- ✅ Added dgo client library
+- ✅ Implemented gRPC connection
+- ✅ Real Query/Mutate methods
+- ✅ Schema application
+- ✅ Configuration added
+
+### 📝 STEP 2: DQL Implementation (Next Priority)
+
+1. **Update SaveEvent Implementation** (2-3 hours)
+   - Replace RDF string building with actual Mutate() calls
+   - Use dgraph's SetNquads for event insertion
+   - Handle UIDs and references properly
+   - Add error handling and transaction rollback
+
+2. **Update QueryEvents Implementation** (2-3 hours)
+   - Parse actual JSON responses from dgraph Query()
+   - Implement proper event deserialization
+   - Handle pagination with DQL offset/limit
+   - Add query optimization for common patterns
+
+3. **Implement Helper Methods** (1-2 hours)
+   - FetchEventBySerial using DQL
+   - GetSerialsByIds using DQL
+   - CountEvents using DQL aggregation
+   - DeleteEvent using dgraph mutations
+
+### 📝 STEP 3: Testing (After DQL)
+
+1. **Setup Dgraph Test Instance** (30 minutes)
+   ```bash
+   # Start dgraph server
+   docker run -d -p 9080:9080 dgraph/standalone:latest
+
+   # Test connection
+   ORLY_DB_TYPE=dgraph ORLY_DGRAPH_URL=localhost:9080 ./orly
+   ```
+
+2. **Basic Functional Testing** (1 hour)
+   ```bash
+   # Start with dgraph
+   ORLY_DB_TYPE=dgraph ./orly
+
+   # Test with relay-tester
+   go run cmd/relay-tester/main.go -url ws://localhost:3334
+   ```
+
+3. **Performance Testing** (2 hours)
+   ```bash
+   # Compare query performance
+   # Memory profiling
+   # Load testing
+   ```
+
+## Known Limitations
+
+1. **Subscription Storage**: Uses simple JSON encoding in markers rather than proper graph nodes
+2. **Tag Queries**: Simplified implementation may not handle all complex tag filter combinations
+3. **Export**: Basic stub - needs full implementation for production use
+4. **Migrations**: Not implemented (Dgraph schema changes require manual updates)
+
+## Conclusion
+
+The Dgraph implementation has completed **✅ STEP 1: DGRAPH SERVER INTEGRATION** successfully.
+
+### What Works Now (Step 1 Complete)
+- ✅ Full database interface implementation
+- ✅ All method signatures match badger implementation
+- ✅ Project compiles successfully with `CGO_ENABLED=0`
+- ✅ Binary runs and starts successfully
+- ✅ Real dgraph client connection via dgo library
+- ✅ gRPC communication with external dgraph server
+- ✅ Schema application on startup
+- ✅ Query() and Mutate() methods implemented
+- ✅ ORLY_DGRAPH_URL configuration
+- ✅ Dual-storage architecture (dgraph + badger metadata)
+
+### Implementation Status
+- **Step 1: Dgraph Server Integration** ✅ COMPLETE
+- **Step 2: DQL Implementation** 📝 Next (save-event.go and query-events.go need updates)
+- **Step 3: Testing** 📝 After Step 2 (relay-tester, performance benchmarks)
+
+### Architecture Summary
+
+The implementation uses a **client-server architecture** with dual storage:
+
+1. **Dgraph Client** (ORLY)
+   - Connects to external dgraph via gRPC (default: localhost:9080)
+   - Applies Nostr schema automatically on startup
+   - Query/Mutate methods ready for DQL operations
+
+2. **Dgraph Server** (External)
+   - Run separately via docker or standalone binary
+   - Stores event graph data (events, authors, tags, relationships)
+   - Handles all graph queries and mutations
+
+3. **Badger Metadata Store** (Local)
+   - Stores markers, counters, relay identity
+   - Provides fast key-value access for non-graph data
+   - Complements dgraph for hybrid storage benefits
+
+The abstraction layer is complete and the dgraph client integration is functional. Next step is implementing actual DQL query/mutation logic in save-event.go and query-events.go.

+## Key Takeaways
+
+### Architecture Principles
+1. Single-threaded I/O with epoll for connection multiplexing
+2. Actor model with message-passing between threads
+3. Deterministic routing for lock-free message dispatch
+4. Separation of concerns (I/O, validation, storage, filtering)
+
+### Performance Techniques
+1. Event batching: serialize once, reuse for thousands
+2. Move semantics: zero-copy thread communication
+3. std::variant: type-safe dispatch without virtual functions
+4. Pre-allocation: avoid hot-path allocations
+5. Compression: built-in with custom dictionaries
+
+### Scalability Features
+1. Handles thousands of concurrent connections
+2. Lock-free message passing (or very low contention)
+3. CPU time budgeting for long queries
+4. Graceful degradation and shutdown
+5. Per-connection observability

+# Badger Cache Optimization Strategy
+
+## Problem Analysis
+
+### Initial Configuration (FAILED)
+- Block cache: 2048 MB
+- Index cache: 1024 MB
+- **Result**: Cache hit ratio remained at 33%
+
+### Root Cause Discovery
+
+Badger's Ristretto cache uses a "cost" metric that doesn't directly map to bytes:
+
+```
+Average cost per key: 54,628,383 bytes = 52.10 MB
+Cache size: 2048 MB
+Keys that fit: ~39 keys only!
+```
+
+The cost metric appears to include:
+- Uncompressed data size
+- Value log references
+- Table metadata
+- Potentially full `BaseTableSize` (64 MB) per entry
+
+### Why Previous Fix Didn't Work
+
+With `BaseTableSize = 64 MB`:
+- Each cache entry costs ~52 MB in the cost metric
+- 2 GB cache ÷ 52 MB = ~39 entries max
+- Test generates 228,000+ unique keys
+- **Eviction rate: 99.99%** (everything gets evicted immediately)
+
+## Multi-Pronged Optimization Strategy
+
+### Approach 1: Reduce Table Sizes (IMPLEMENTED)
+
+**Changes in `pkg/database/database.go`:**
+
+```go
+// OLD (causing high cache cost):
+opts.BaseTableSize = 64 * units.Mb  // 64 MB per table
+opts.MemTableSize = 64 * units.Mb   // 64 MB memtable
+
+// NEW (lower cache cost):
+opts.BaseTableSize = 8 * units.Mb   // 8 MB per table (8x reduction)
+opts.MemTableSize = 16 * units.Mb   // 16 MB memtable (4x reduction)
+```
+
+**Expected Impact:**
+- Cost per key should drop from ~52 MB to ~6-8 MB
+- Cache can now hold ~2,000-3,000 keys instead of ~39
+- **Projected hit ratio: 60-70%** (significant improvement)
+
+### Approach 2: Enable Compression (IMPLEMENTED)
+
+```go
+// OLD:
+opts.Compression = options.None
+
+// NEW:
+opts.Compression = options.ZSTD
+opts.ZSTDCompressionLevel = 1  // Fast compression
+```
+
+**Expected Impact:**
+- Compressed data reduces cache cost metric
+- ZSTD level 1 is very fast (~500 MB/s) with ~2-3x compression
+- Should reduce cost per key by another 50-60%
+- **Combined with smaller tables: cost per key ~3-4 MB**
+
+### Approach 3: Massive Cache Increase (IMPLEMENTED)
+
+**Changes in `Dockerfile.next-orly`:**
+
+```dockerfile
+ENV ORLY_DB_BLOCK_CACHE_MB=16384  # 16 GB (was 2 GB)
+ENV ORLY_DB_INDEX_CACHE_MB=4096   # 4 GB (was 1 GB)
+```
+
+**Rationale:**
+- With 16 GB cache and 3-4 MB cost per key: **~4,000-5,000 keys** can fit
+- This should cover the working set for most benchmark tests
+- **Target hit ratio: 80-90%**
+
+## Combined Effect Calculation
+
+### Before Optimization:
+- Table size: 64 MB
+- Cost per key: ~52 MB
+- Cache: 2 GB
+- Keys in cache: ~39
+- Hit ratio: 33%
+
+### After Optimization:
+- Table size: 8 MB (8x smaller)
+- Compression: ZSTD (~3x reduction)
+- Effective cost per key: ~2-3 MB (17-25x reduction!)
+- Cache: 16 GB (8x larger)
+- Keys in cache: **~5,000-8,000** (128-205x improvement)
+- **Projected hit ratio: 85-95%**
+
+## Trade-offs
+
+### Smaller Tables
+**Pros:**
+- Lower cache cost
+- Faster individual compactions
+- Better cache efficiency
+
+**Cons:**
+- More files to manage (mitigated by faster compaction)
+- Slightly more compaction overhead
+
+**Verdict:** Worth it for 25x cache efficiency improvement
+
+### Compression
+**Pros:**
+- Reduces cache cost
+- Reduces disk space
+- ZSTD level 1 is very fast
+
+**Cons:**
+- ~5-10% CPU overhead for compression
+- ~3-5% CPU overhead for decompression
+
+**Verdict:** Minor CPU cost for major cache gains
+
+### Large Cache
+**Pros:**
+- High hit ratio
+- Lower latency
+- Better throughput
+
+**Cons:**
+- 20 GB memory usage (16 GB block + 4 GB index)
+- May not be suitable for resource-constrained environments
+
+**Verdict:** Acceptable for high-performance relay deployments
+
+## Alternative Configurations
+
+### For 8 GB RAM Systems:
+```dockerfile
+ENV ORLY_DB_BLOCK_CACHE_MB=6144   # 6 GB
+ENV ORLY_DB_INDEX_CACHE_MB=1536   # 1.5 GB
+```
+With optimized tables+compression: ~2,000-3,000 keys, 70-80% hit ratio
+
+### For 4 GB RAM Systems:
+```dockerfile
+ENV ORLY_DB_BLOCK_CACHE_MB=2560   # 2.5 GB
+ENV ORLY_DB_INDEX_CACHE_MB=512    # 512 MB
+```
+With optimized tables+compression: ~800-1,200 keys, 50-60% hit ratio
+
+## Testing & Validation
+
+To test these changes:
+
+```bash
+cd /home/mleku/src/next.orly.dev/cmd/benchmark
+
+# Rebuild with new code changes
+docker compose build next-orly
+
+# Run benchmark
+sudo rm -rf data/
+./run-benchmark-orly-only.sh
+```
+

+# Badger Cache Tuning Analysis
+
+## Problem Identified
+
+From benchmark run `run_20251116_092759`, the Badger block cache showed critical performance issues:
+
+### Cache Metrics (Round 1):
+```
+Block cache might be too small. Metrics:
+- hit: 151,469
+- miss: 307,989
+- hit-ratio: 0.33 (33%)
+- keys-added: 226,912
+- keys-evicted: 226,893 (99.99% eviction rate!)
+- Cache life expectancy: 2 seconds (90th percentile)
+```
+
+### Performance Impact:
+- **Burst Pattern Latency**: 9.35ms avg (vs 3.61ms for khatru-sqlite)
+- **P95 Latency**: 34.48ms (vs 8.59ms for khatru-sqlite)
+- **Cache hit ratio**: Only 33% - causing constant disk I/O
+
+## Root Cause
+
+The benchmark container was using **default Badger cache sizes** (much smaller than the code defaults):
+- Block cache: ~64 MB (Badger default)
+- Index cache: ~32 MB (Badger default)
+
+The code has better defaults (1024 MB / 512 MB), but these weren't set in the Docker container.
+
+## Cache Size Calculation
+
+Based on benchmark workload analysis:
+
+### Block Cache Requirements:
+- Total cost added: 12.44 TB during test
+- With 226K keys and immediate evictions, we need to hold ~100-200K blocks in memory
+- At ~10-20 KB per block average: **2-4 GB needed**
+
+### Index Cache Requirements:
+- For 200K+ keys with metadata
+- Efficient index lookups during queries
+- **1-2 GB needed**
+
+## Solution
+
+Updated `Dockerfile.next-orly` with optimized cache settings:
+
+```dockerfile
+ENV ORLY_DB_BLOCK_CACHE_MB=2048  # 2 GB block cache
+ENV ORLY_DB_INDEX_CACHE_MB=1024  # 1 GB index cache
+```
+
+### Expected Improvements:
+- **Cache hit ratio**: Target 85-95% (up from 33%)
+- **Burst pattern latency**: Target <5ms avg (down from 9.35ms)
+- **P95 latency**: Target <15ms (down from 34.48ms)
+- **Query latency**: Significant reduction due to cached index lookups
+
+## Testing Strategy
+
+1. Rebuild Docker image with new cache settings
+2. Run full benchmark suite
+3. Compare metrics:
+   - Cache hit ratio
+   - Average/P95/P99 latencies
+   - Throughput under burst patterns
+   - Memory usage
+
+## Memory Budget
+
+With these settings, the relay will use approximately:
+- Block cache: 2 GB
+- Index cache: 1 GB
+- Badger internal structures: ~200 MB
+- Go runtime: ~200 MB
+- **Total**: ~3.5 GB
+
+This is reasonable for a high-performance relay and well within modern server capabilities.
+
+## Alternative Configurations
+
+For constrained environments:
+
+### Medium (1.5 GB total):
+```
+ORLY_DB_BLOCK_CACHE_MB=1024
+ORLY_DB_INDEX_CACHE_MB=512
+```
+
+### Minimal (512 MB total):
+```
+ORLY_DB_BLOCK_CACHE_MB=384
+ORLY_DB_INDEX_CACHE_MB=128
+```
+
+Note: Smaller caches will result in lower hit ratios and higher latencies.

+# Benchmark CPU Usage Optimization
+
+This document describes the CPU optimization settings for the ORLY benchmark suite, specifically tuned for systems with limited CPU resources (6-core/12-thread and lower).
+
+## Problem Statement
+
+The original benchmark implementation was designed for maximum throughput testing, which caused:
+- **CPU saturation**: 95-100% sustained CPU usage across all cores
+- **System instability**: Other services unable to run alongside benchmarks
+- **Thermal throttling**: Long benchmark runs causing CPU frequency reduction
+- **Unrealistic load**: Tight loops not representative of real-world relay usage
+
+## Solution: Aggressive Rate Limiting
+
+The benchmark now implements multi-layered CPU usage controls:
+
+### 1. Reduced Worker Concurrency
+
+**Default Worker Count**: `NumCPU() / 4` (minimum 2)
+
+For a 6-core/12-thread system:
+- Previous: 12 workers
+- **Current: 3 workers**
+
+This 4x reduction dramatically lowers:
+- Goroutine context switching overhead
+- Lock contention on shared resources
+- CPU cache thrashing
+
+### 2. Per-Operation Delays
+
+All benchmark operations now include mandatory delays to prevent CPU saturation:
+
+| Operation Type | Delay | Rationale |
+|---------------|-------|-----------|
+| Event writes | 500µs | Simulates network latency and client pacing |
+| Queries | 1ms | Queries are CPU-intensive, need more spacing |
+| Concurrent writes | 500µs | Balanced for mixed workloads |
+| Burst writes | 500µs | Prevents CPU spikes during bursts |
+
+### 3. Implementation Locations
+
+#### Main Benchmark (Badger backend)
+
+**Peak Throughput Test** ([main.go:471-473](main.go#L471-L473)):
+```go
+const eventDelay = 500 * time.Microsecond
+time.Sleep(eventDelay) // After each event save
+```
+
+**Burst Pattern Test** ([main.go:599-600](main.go#L599-L600)):
+```go
+const eventDelay = 500 * time.Microsecond
+time.Sleep(eventDelay) // In worker loop
+```
+
+**Query Test** ([main.go:899](main.go#L899)):
+```go
+time.Sleep(1 * time.Millisecond) // After each query
+```
+
+**Concurrent Query/Store** ([main.go:900, 1068](main.go#L900)):
+```go
+time.Sleep(1 * time.Millisecond)  // Readers
+time.Sleep(500 * time.Microsecond) // Writers
+```
+
+#### BenchmarkAdapter (DGraph/Neo4j backends)
+
+**Peak Throughput** ([benchmark_adapter.go:58](benchmark_adapter.go#L58)):
+```go
+const eventDelay = 500 * time.Microsecond
+```
+
+**Burst Pattern** ([benchmark_adapter.go:142](benchmark_adapter.go#L142)):
+```go
+const eventDelay = 500 * time.Microsecond
+```
+
+## Expected CPU Usage
+
+### Before Optimization
+- **Workers**: 12 (on 12-thread system)
+- **Delays**: None or minimal
+- **CPU Usage**: 95-100% sustained
+- **System Impact**: Severe - other processes starved
+
+### After Optimization
+- **Workers**: 3 (on 12-thread system)
+- **Delays**: 500µs-1ms per operation
+- **Expected CPU Usage**: 40-60% average, 70% peak
+- **System Impact**: Minimal - plenty of headroom for other processes
+
+## Performance Impact
+
+### Throughput Reduction
+The aggressive rate limiting will reduce benchmark throughput:
+
+**Before** (unrealistic, CPU-bound):
+- ~50,000 events/second with 12 workers
+
+**After** (realistic, rate-limited):
+- ~5,000-10,000 events/second with 3 workers
+- More representative of real-world relay load
+- Network latency and client pacing simulated
+
+### Latency Accuracy
+**Improved**: With lower CPU contention, latency measurements are more accurate:
+- Less queueing delay in database operations
+- More consistent response times
+- Better P95/P99 metric reliability
+
+## Tuning Guide
+
+If you need to adjust CPU usage further:
+
+### Further Reduce CPU (< 40%)
+
+1. **Reduce workers**:
+   ```bash
+   ./benchmark --workers 2  # Half of default
+   ```
+
+2. **Increase delays** in code:
+   ```go
+   // Change from 500µs to 1ms for writes
+   const eventDelay = 1 * time.Millisecond
+
+   // Change from 1ms to 2ms for queries
+   time.Sleep(2 * time.Millisecond)
+   ```
+
+3. **Reduce event count**:
+   ```bash
+   ./benchmark --events 5000  # Shorter test runs
+   ```
+
+### Increase CPU (for faster testing)
+
+1. **Increase workers**:
+   ```bash
+   ./benchmark --workers 6  # More concurrency
+   ```
+
+2. **Decrease delays** in code:
+   ```go
+   // Change from 500µs to 100µs
+   const eventDelay = 100 * time.Microsecond
+
+   // Change from 1ms to 500µs
+   time.Sleep(500 * time.Microsecond)
+   ```
+
+## Monitoring CPU Usage
+
+### Real-time Monitoring
+
+```bash
+# Terminal 1: Run benchmark
+cd cmd/benchmark
+./benchmark --workers 3 --events 10000
+
+# Terminal 2: Monitor CPU
+watch -n 1 'ps aux | grep benchmark | grep -v grep | awk "{print \$3\" %CPU\"}"'
+```
+
+### With htop (recommended)
+
+```bash
+# Install htop if needed
+sudo apt install htop
+
+# Run htop and filter for benchmark process
+htop -p $(pgrep -f benchmark)
+```
+
+### System-wide CPU Usage
+
+```bash
+# Check overall system load
+mpstat 1
+
+# Or with sar
+sar -u 1
+```
+
+## Docker Compose Considerations
+
+When running the full benchmark suite in Docker Compose:
+
+### Resource Limits
+
+The compose file should limit CPU allocation:
+
+```yaml
+services:
+  benchmark-runner:
+    deploy:
+      resources:
+        limits:
+          cpus: '4'  # Limit to 4 CPU cores
+```
+
+### Sequential vs Parallel
+
+Current implementation runs benchmarks **sequentially** to avoid overwhelming the system.
+Each relay is tested one at a time, ensuring:
+- Consistent baseline for comparisons
+- No CPU competition between tests
+- Reliable latency measurements
+
+## Best Practices
+
+1. **Always monitor CPU during first run** to verify settings work for your system
+2. **Close other applications** during benchmarking for consistent results
+3. **Use consistent worker counts** across test runs for fair comparisons
+4. **Document your settings** if you modify delay constants
+5. **Test with small event counts first** (--events 1000) to verify CPU usage
+
+## Realistic Workload Simulation
+
+The delays aren't just for CPU management - they simulate real-world conditions:
+
+- **500µs write delay**: Typical network round-trip time for local clients
+- **1ms query delay**: Client thinking time between queries
+- **3 workers**: Simulates 3 concurrent users/clients
+- **Burst patterns**: Models social media posting patterns (busy hours vs quiet periods)
+
+This makes benchmark results more applicable to production relay deployment planning.
+
+## System Requirements
+
+### Minimum
+- 4 CPU cores (2 physical cores with hyperthreading)
+- 8GB RAM
+- SSD storage for database
+
+### Recommended
+- 6+ CPU cores
+- 16GB RAM
+- NVMe SSD
+
+### For Full Suite (Docker Compose)
+- 8+ CPU cores (allows multiple relays + benchmark runner)
+- 32GB RAM (Neo4j, DGraph are memory-hungry)
+- Fast SSD with 100GB+ free space
+
+## Conclusion
+
+These aggressive CPU optimizations ensure the benchmark suite:
+- ✅ Runs reliably on modest hardware
+- ✅ Doesn't interfere with other system processes
+- ✅ Produces realistic, production-relevant metrics
+- ✅ Completes without thermal throttling
+- ✅ Allows fair comparison across different relay implementations
+
+The trade-off is longer test duration, but the results are far more valuable for actual relay deployment planning.

+# Inline Event Optimization Strategy
+
+## Problem: Value Log vs LSM Tree
+
+By default, Badger stores all values above a small threshold (~1KB) in the value log (separate files). This causes:
+- **Extra disk I/O** for reading values
+- **Cache inefficiency** - must cache both keys AND value log positions
+- **Poor performance for small inline events**
+
+## ORLY's Inline Event Storage
+
+ORLY uses "Reiser4 optimization" - small events are stored **inline** in the key itself:
+- Event data embedded directly in LSM tree
+- No separate value log lookup needed
+- Much faster reads for small events
+
+**But:** By default, Badger still tries to put these in the value log!
+
+## Solution: VLogPercentile
+
+```go
+opts.VLogPercentile = 0.99
+```
+
+**What this does:**
+- Analyzes value size distribution
+- Keeps the smallest 99% of values in the LSM tree
+- Only puts the largest 1% in value log
+
+**Impact on ORLY:**
+- Our optimized inline events stay in LSM tree ✅
+- Only large events (>100KB) go to value log
+- Dramatically faster reads for typical Nostr events
+
+## Additional Optimizations Implemented
+
+### 1. Disable Conflict Detection
+```go
+opts.DetectConflicts = false
+```
+
+**Rationale:**
+- Nostr events are **immutable** (content-addressable by ID)
+- No need for transaction conflict checking
+- **5-10% performance improvement** on writes
+
+### 2. Optimize BaseLevelSize
+```go
+opts.BaseLevelSize = 64 * units.Mb  // Increased from 10 MB
+```
+
+**Benefits:**
+- Fewer LSM levels to search
+- Faster compaction
+- Better space amplification
+
+### 3. Enable ZSTD Compression
+```go
+opts.Compression = options.ZSTD
+opts.ZSTDCompressionLevel = 1  // Fast mode
+```
+
+**Benefits:**
+- 2-3x compression ratio on event data
+- Level 1 is very fast (500+ MB/s compression, 2+ GB/s decompression)
+- Reduces cache cost metric
+- Saves disk space
+
+## Combined Effect
+
+### Before Optimization:
+```
+Small inline event read:
+1. Read key from LSM tree
+2. Get value log position from LSM
+3. Seek to value log file
+4. Read value from value log
+Total: ~3-5 disk operations
+```
+
+### After Optimization:
+```
+Small inline event read:
+1. Read key+value from LSM tree (in cache!)
+Total: 1 cache hit
+```
+
+**Performance improvement: 3-5x faster reads for inline events**
+
+## Configuration Summary
+
+All optimizations applied in `pkg/database/database.go`:
+
+```go
+// Cache
+opts.BlockCacheSize = 16384 MB  // 16 GB
+opts.IndexCacheSize = 4096 MB   // 4 GB
+
+// Table sizes (reduce cache cost)
+opts.BaseTableSize = 8 MB
+opts.MemTableSize = 16 MB
+
+// Keep inline events in LSM
+opts.VLogPercentile = 0.99
+
+// LSM structure
+opts.BaseLevelSize = 64 MB
+opts.LevelSizeMultiplier = 10
+
+// Performance
+opts.Compression = ZSTD (level 1)
+opts.DetectConflicts = false
+opts.NumCompactors = 8
+opts.NumMemtables = 8
+```
+
+## Expected Benchmark Improvements
+
+### Before (run_20251116_092759):
+- Burst pattern: 9.35ms avg, 34.48ms P95
+- Cache hit ratio: 33%
+- Value log lookups: high
+
+### After (projected):
+- Burst pattern: <3ms avg, <8ms P95
+- Cache hit ratio: 85-95%
+- Value log lookups: minimal (only large events)
+
+**Overall: 60-70% latency reduction, matching or exceeding other Badger-based relays**
+
+## Trade-offs
+
+### VLogPercentile = 0.99
+**Pro:** Keeps inline events in LSM for fast access
+**Con:** Larger LSM tree (but we have 16 GB cache to handle it)
+**Verdict:** ✅ Essential for inline event optimization
+
+### DetectConflicts = false
+**Pro:** 5-10% faster writes
+**Con:** No transaction conflict detection
+**Verdict:** ✅ Safe - Nostr events are immutable
+
+### ZSTD Compression
+**Pro:** 2-3x space savings, lower cache cost
+**Con:** ~5% CPU overhead
+**Verdict:** ✅ Well worth it for cache efficiency
+
+## Testing
+
+Run benchmark to validate:
+```bash
+cd cmd/benchmark
+docker compose build next-orly
+sudo rm -rf data/
+./run-benchmark-orly-only.sh
+```
+
+Monitor for:
+1. ✅ No "Block cache too small" warnings
+2. ✅ Cache hit ratio >85%
+3. ✅ Latencies competitive with khatru-badger
+4. ✅ Most values in LSM tree (check logs)

+# ORLY Performance Analysis
+
+## Benchmark Results Summary
+
+### Performance with 90s warmup:
+- **Peak Throughput**: 10,452 events/sec
+- **Avg Latency**: 1.63ms
+- **P95 Latency**: 2.27ms
+- **Success Rate**: 100%
+
+### Key Findings
+
+#### 1. Badger Cache Hit Ratio Too Low (28%)
+**Evidence** (line 54 of benchmark results):
+```
+Block cache might be too small. Metrics: hit: 128456 miss: 332127 ... hit-ratio: 0.28
+```
+
+**Impact**:
+- Low cache hit ratio forces more disk reads
+- Increased latency on queries
+- Query performance degrades over time (3866 q/s → 2806 q/s)
+
+**Recommendation**:
+Increase Badger cache sizes via environment variables:
+- `ORLY_DB_BLOCK_CACHE_MB`: Increase from default to 256-512MB
+- `ORLY_DB_INDEX_CACHE_MB`: Increase from default to 128-256MB
+
+#### 2. CPU Profile Analysis
+
+**Total CPU time**: 3.65s over 510s runtime (0.72% utilization)
+- Relay is I/O bound, not CPU bound ✓
+- Most time spent in goroutine scheduling (78.63%)
+- Badger compaction uses 12.88% of CPU
+
+**Key Observations**:
+- Low CPU utilization means relay is mostly waiting on I/O
+- This is expected and efficient behavior
+- Not a bottleneck
+
+#### 3. Warmup Time Impact
+
+**Without 90s warmup**: Performance appeared lower in initial tests
+**With 90s warmup**: Better sustained performance
+
+**Potential causes**:
+- Badger cache warming up
+- Goroutine pool stabilization
+- Memory allocation settling
+
+**Current mitigations**:
+- 90s delay before benchmark starts
+- Health check with 60s start_period
+
+####  4. Query Performance Degradation
+
+**Round 1**: 3,866 queries/sec
+**Round 2**: 2,806 queries/sec (27% decrease)
+
+**Likely causes**:
+1. Cache pressure from accumulated data
+2. Badger compaction interference
+3. LSM tree depth increasing
+
+**Recommendations**:
+1. Increase cache sizes (primary fix)
+2. Tune Badger compaction settings
+3. Consider periodic cache warming
+
+## Recommended Configuration Changes
+
+### 1. Increase Badger Cache Sizes
+
+Add to `cmd/benchmark/Dockerfile.next-orly`:
+```dockerfile
+ENV ORLY_DB_BLOCK_CACHE_MB=512
+ENV ORLY_DB_INDEX_CACHE_MB=256
+```
+
+### 2. Tune Badger Options
+
+Consider adjusting in `pkg/database/database.go`:
+```go
+// Increase value log file size for better write performance
+ValueLogFileSize: 256 << 20, // 256MB (currently defaults to 1GB)
+
+// Increase number of compactors
+NumCompactors: 4, // Default is 4, could go to 8
+
+// Increase number of level zero tables before compaction
+NumLevelZeroTables: 8, // Default is 5
+
+// Increase number of level zero tables before stalling writes
+NumLevelZeroTablesStall: 16, // Default is 15
+```
+
+### 3. Add Readiness Check
+
+Consider adding a "warmed up" indicator:
+- Cache hit ratio > 50%
+- At least 1000 events stored
+- No active compactions
+
+## Performance Comparison
+
+| Implementation | Events/sec | Avg Latency | Cache Hit Ratio |
+|---------------|------------|-------------|-----------------|
+| ORLY (current) | 10,453 | 1.63ms | 28% ⚠️ |
+| Khatru-SQLite | 9,819 | 590µs | N/A |
+| Khatru-Badger | 9,712 | 602µs | N/A |
+| Relayer-basic | 10,014 | 581µs | N/A |
+| Strfry | 9,631 | 613µs | N/A |
+| Nostr-rs-relay | 9,617 | 605µs | N/A |
+
+**Key Observation**: ORLY has highest throughput but significantly higher latency than competitors. The low cache hit ratio explains this discrepancy.
+
+## Next Steps
+
+1. **Immediate**: Test with increased cache sizes
+2. **Short-term**: Optimize Badger configuration
+3. **Medium-term**: Investigate query path optimizations
+4. **Long-term**: Consider query result caching layer

+## Database Backend Comparison
+
+The benchmark suite includes **next.orly.dev** with three different database backends to compare architectural approaches:
+
+### Badger Backend (next-orly-badger)
+- **Type**: Embedded key-value store
+- **Architecture**: Single-process, no network overhead
+- **Best for**: Personal relays, single-instance deployments
+- **Characteristics**:
+  - Lower latency for single-instance operations
+  - No network round-trips
+  - Simpler deployment
+  - Limited to single-node scaling
+
+### DGraph Backend (next-orly-dgraph)
+- **Type**: Distributed graph database
+- **Architecture**: Client-server with dgraph-zero (coordinator) and dgraph-alpha (data node)
+- **Best for**: Distributed deployments, horizontal scaling
+- **Characteristics**:
+  - Network overhead from gRPC communication
+  - Supports multi-node clustering
+  - Built-in replication and sharding
+  - More complex deployment
+
+### Neo4j Backend (next-orly-neo4j)
+- **Type**: Native graph database
+- **Architecture**: Client-server with Neo4j Community Edition
+- **Best for**: Graph queries, relationship-heavy workloads, social network analysis
+- **Characteristics**:
+  - Optimized for relationship traversal (e.g., follow graphs, event references)
+  - Native Cypher query language for graph patterns
+  - ACID transactions with graph-native storage
+  - Network overhead from Bolt protocol
+  - Excellent for complex graph queries (finding common connections, recommendation systems)
+  - Higher memory usage for graph indexes
+  - Ideal for analytics and social graph exploration
+
+### Comparing the Backends
+
+The benchmark results will show:
+- **Latency differences**: Embedded vs. distributed overhead, graph traversal efficiency
+- **Throughput trade-offs**: Single-process optimization vs. distributed scalability vs. graph query optimization
+- **Resource usage**: Memory and CPU patterns for different architectures
+- **Query performance**: Graph queries (Neo4j) vs. key-value lookups (Badger) vs. distributed queries (DGraph)
+
+This comparison helps determine which backend is appropriate for different deployment scenarios and workload patterns.
