+
+**Project-Specific Information for AI Agents Working with C-Relay in Architect Mode**
+
+## Critical Architecture Understanding
+
+### System Architecture Overview
+C-Relay implements a **unique event-based configuration architecture** that fundamentally differs from traditional Nostr relays:
+
+```
+┌─────────────────┐    ┌──────────────────┐    ┌─────────────────┐
+│   WebSocket     │    │  Configuration   │    │    Database     │
+│   + HTTP        │◄──►│  Event System    │◄──►│   (SQLite)      │
+│   (Port 8888)   │    │  (Kind 33334)    │    │  Schema v4      │
+└─────────────────┘    └──────────────────┘    └─────────────────┘

+```
+
+### Core Architectural Principles
+
+#### 1. Event-Driven Configuration
+**Design Philosophy**: Configuration as cryptographically signed events rather than files
+- **Benefits**: Auditability, remote management, tamper-evidence
+- **Trade-offs**: Complexity in configuration changes, admin key management burden
+- **Implementation**: Kind 33334 events stored in same database as relay events
+
+#### 2. Identity-Based Database Naming
+**Design Philosophy**: Database file named by relay's generated public key
+- **Benefits**: Prevents database conflicts, enables multi-relay deployments
+- **Trade-offs**: Cannot predict database filename, complicates backup strategies
+- **Implementation**: `<relay_pubkey>.db` created in build/ directory
+
+#### 3. Single-Binary Deployment
+**Design Philosophy**: All functionality embedded in one executable
+- **Benefits**: Simple deployment, no external dependencies to manage
+- **Trade-offs**: Larger binary size, harder to modularize
+- **Implementation**: SQL schema embedded as header file, nostr_core_lib as submodule
+
+#### 4. Dual-Protocol Support
+**Design Philosophy**: WebSocket (Nostr) and HTTP (NIP-11) on same port
+- **Benefits**: Simplified port management, reduced infrastructure complexity
+- **Trade-offs**: Protocol detection overhead, libwebsockets dependency
+- **Implementation**: Request routing based on HTTP headers and upgrade requests
+
+## Architectural Decision Analysis
+
+### Configuration System Design
+**Traditional Approach vs C-Relay:**
+```
+Traditional:           C-Relay:
+config.json     →     kind 33334 events
+ENV variables   →     cryptographically signed tags
+File watching   →     database polling/restart
+```
+
+**Implications for Extensions:**
+- Configuration changes require event signing capabilities
+- No hot-reloading without architectural changes
+- Admin key loss = complete database reset required
+
+### Database Architecture Decisions
+**Schema Design Philosophy:**
+- **Event Tags as JSON**: Separate table with JSON column instead of normalized relations
+- **Application-Level Filtering**: NIP-40 expiration handled in C, not SQL
+- **Embedded Schema**: Version 4 schema compiled into binary
+
+**Scaling Considerations:**
+- SQLite suitable for small-to-medium relays (< 10k concurrent connections)
+- Single-writer limitation of SQLite affects write-heavy workloads
+- JSON tag storage optimizes for read performance over write normalization
+
+### Memory Management Architecture
+**Thread Safety Model:**
+- Global subscription manager with mutex protection
+- Per-client subscription limits enforced in memory
+- WebSocket connection state managed by libwebsockets
+
+**Resource Management:**
+- JSON objects use reference counting (jansson library)
+- String duplication pattern for configuration values
+- Automatic cleanup on client disconnect
+
+## Architectural Extension Points
+
+### Adding New Configuration Options
+**Required Changes:**
+1. Update [`default_config_event.h`](src/default_config_event.h) template
+2. Add parsing logic in [`config.c`](src/config.c) `load_config_from_database()`
+3. Add global config struct field in [`config.h`](src/config.h)
+4. Update documentation in [`docs/configuration_guide.md`](docs/configuration_guide.md)
+
+### Adding New NIP Support
+**Integration Pattern:**
+1. Event validation in [`request_validator.c`](src/request_validator.c)
+2. Protocol handling in [`main.c`](src/main.c) WebSocket callback
+3. Database storage considerations in schema
+4. Add test in `tests/` directory
+
+### Scaling Architecture
+**Current Limitations:**
+- Single process, no horizontal scaling
+- SQLite single-writer bottleneck
+- Memory-based subscription management
+
+**Potential Extensions:**
+- Redis for subscription state sharing
+- PostgreSQL for better concurrent write performance
+- Load balancer for read scaling with multiple instances
+
+## Deployment Architecture Patterns
+
+### Development Deployment
+```
+Developer Machine:
+├── ./make_and_restart_relay.sh
+├── build/c_relay_x86
+├── build/<relay_pubkey>.db
+└── relay.log
+```
+
+### Production SystemD Deployment
+```
+/opt/c-relay/:
+├── c_relay_x86
+├── <relay_pubkey>.db
+├── systemd service (c-relay.service)
+└── c-relay user isolation
+```
+
+### Container Deployment Architecture
+```
+Container:
+├── Multi-stage build (deps + binary)
+├── Volume mount for database persistence
+├── Health checks via NIP-11 endpoint
+└── Signal handling for graceful shutdown
+```
+
+### Reverse Proxy Architecture
+```
+Internet → Nginx/HAProxy → C-Relay
+                       ├── WebSocket upgrade handling
+                       ├── SSL termination
+                       └── Rate limiting
+```
+
+## Security Architecture Considerations
+
+### Key Management Design
+**Admin Key Security Model:**
+- Generated once, displayed once, never stored
+- Required for all configuration changes
+- Loss requires complete database reset
+
+**Relay Identity Model:**
+- Separate keypair for relay identity
+- Public key used for database naming
+- Private key never exposed to clients
+
+### Event Validation Pipeline
+```
+WebSocket Input → JSON Parse → Schema Validate → Signature Verify → Store
+                             ↓                 ↓                  ↓
+                    reject    reject          reject           success
+```
+
+### Attack Surface Analysis
+**Network Attack Vectors:**
+- WebSocket connection flooding (mitigated by libwebsockets limits)
+- JSON parsing attacks (handled by jansson library bounds checking)
+- SQLite injection (prevented by prepared statements)
+
+**Configuration Attack Vectors:**
+- Admin key compromise (complete relay control)
+- Event signature forgery (prevented by nostr_core_lib validation)
+- Replay attacks (event timestamp validation required)
+
+## Non-Obvious Architectural Considerations
+
+### Database Evolution Strategy
+**Current Limitations:**
+- Schema changes require database recreation
+- No migration system for configuration events
+- Version 4 schema embedded in binary
+
+**Future Architecture Needs:**
+- Schema versioning and migration system
+- Backward compatibility for configuration events
+- Database backup/restore procedures
+
+### Configuration Event Lifecycle
+**Event Flow:**
+```
+Admin Signs Event → WebSocket Submit → Validate → Store → Restart Required
+                                    ↓            ↓         ↓
+                              Signature Check   Database  Config Reload
+```
+
+**Architectural Implications:**
+- No hot configuration reloading
+- Configuration changes require planned downtime
+- Event ordering matters for multiple simultaneous changes
+
+### Cross-Architecture Deployment
+**Build System Architecture:**
+- Auto-detection of host architecture
+- Cross-compilation support for ARM64
+- Architecture-specific binary outputs
+
+**Deployment Implications:**
+- Binary must match target architecture
+- Dependencies must be available for target architecture
+- Debug tooling architecture-specific
+
+### Performance Architecture Characteristics
+**Bottlenecks:**
+1. **SQLite Write Performance**: Single writer limitation
+2. **JSON Parsing**: Per-event parsing overhead
+3. **Signature Validation**: Cryptographic operations per event
+4. **Memory Management**: JSON object lifecycle management
+
+**Optimization Points:**
+- Prepared statement reuse
+- Connection pooling for concurrent reads
+- Event batching for bulk operations
+- Subscription indexing strategies
+
+### Integration Architecture Patterns
+**Monitoring Integration:**
+- NIP-11 endpoint for health checks
+- Log file monitoring for operational metrics
+- Database query monitoring for performance
+- Process monitoring for resource usage
+
+**Backup Architecture:**
+- Database file backup (SQLite file copy)
+- Configuration event export/import
+- Admin key secure storage (external to relay)
+
+### Future Extension Architectures
+**Multi-Relay Coordination:**
+- Database sharding by event kind
+- Cross-relay event synchronization
+- Distributed configuration management
+
+**Plugin Architecture Possibilities:**
+- Event processing pipeline hooks
+- Custom validation plugins
+- External authentication providers
+
+**Scaling Architecture Options:**
+- Read replicas with PostgreSQL migration
+- Event stream processing with message queues
+- Microservice decomposition (auth, storage, validation)
+
+## Architectural Anti-Patterns to Avoid
+
+1. **Configuration File Addition**: Breaks event-based config paradigm
+2. **Direct Database Modification**: Bypasses signature validation
+3. **Hard-Coded Ports**: Conflicts with auto-fallback system
+4. **Schema Modifications**: Requires database recreation
+5. **Admin Key Storage**: Violates security model
+6. **Blocking Operations**: Interferes with WebSocket event loop
+7. **Memory Leaks**: JSON objects must be properly reference counted
+8. **Thread Unsafe Operations**: Global state requires proper synchronization
+
+## Architecture Decision Records (Implicit)
+
+### Decision: Event-Based Configuration
+**Context**: Traditional config files vs. cryptographic auditability
+**Decision**: Store configuration as signed Nostr events
+**Consequences**: Complex configuration changes, enhanced security, remote management capability
+
+### Decision: SQLite Database
+**Context**: Database choice for relay storage
+**Decision**: Embedded SQLite with JSON tag storage
+**Consequences**: Simple deployment, single-writer limitation, application-level filtering
+
+### Decision: Single Binary Deployment
+**Context**: Dependency management vs. deployment simplicity
+**Decision**: Embed all dependencies and schema in binary
+**Consequences**: Larger binary, simple deployment, version coupling
+
+### Decision: Dual Protocol Support
+**Context**: WebSocket for Nostr, HTTP for NIP-11
+**Decision**: Same port serves both protocols
+**Consequences**: Simplified deployment, protocol detection overhead, libwebsockets dependency
+
+These architectural decisions form the foundation of C-Relay's unique approach to Nostr relay implementation and should be carefully considered when planning extensions or modifications.

+NIP-07
+======
+
+`window.nostr` capability for web browsers
+------------------------------------------
+
+`draft` `optional`
+
+The `window.nostr` object may be made available by web browsers or extensions and websites or web-apps may make use of it after checking its availability.
+
+That object must define the following methods:
+
+```
+async window.nostr.getPublicKey(): string // returns a public key as hex
+async window.nostr.signEvent(event: { created_at: number, kind: number, tags: string[][], content: string }): Event // takes an event object, adds `id`, `pubkey` and `sig` and returns it
+```
+
+Aside from these two basic above, the following functions can also be implemented optionally:
+```
+async window.nostr.nip04.encrypt(pubkey, plaintext): string // returns ciphertext and iv as specified in nip-04 (deprecated)
+async window.nostr.nip04.decrypt(pubkey, ciphertext): string // takes ciphertext and iv as specified in nip-04 (deprecated)
+async window.nostr.nip44.encrypt(pubkey, plaintext): string // returns ciphertext as specified in nip-44
+async window.nostr.nip44.decrypt(pubkey, ciphertext): string // takes ciphertext as specified in nip-44
+```
+
+### Recommendation to Extension Authors
+To make sure that the `window.nostr` is available to nostr clients on page load, the authors who create Chromium and Firefox extensions should load their scripts by specifying `"run_at": "document_end"` in the extension's manifest.
+
+
+### Implementation
+
+See https://github.com/aljazceru/awesome-nostr#nip-07-browser-extensions.

+# AGENTS.md - AI Agent Integration Guide
+
+**Project-Specific Information for AI Agents Working with C-Relay**
+
+## Critical Build Commands
+
+### Primary Build Command
+```bash
+./make_and_restart_relay.sh
+```
+**Never use `make` directly.** The project requires the custom restart script which:
+- Handles database preservation/cleanup based on flags
+- Manages architecture-specific binary detection (x86/ARM64)
+- Performs automatic process cleanup and port management
+- Starts relay in background with proper logging
+
+### Architecture-Specific Binary Outputs
+- **x86_64**: `./build/c_relay_x86`
+- **ARM64**: `./build/c_relay_arm64`
+- **Other**: `./build/c_relay_$(ARCH)`
+
+### Database File Naming Convention
+- **Format**: `<relay_pubkey>.db` (NOT `.nrdb` as shown in docs)
+- **Location**: Created in `build/` directory during execution
+- **Cleanup**: Use `--preserve-database` flag to retain between builds
+
+## Critical Integration Issues
+
+### Event-Based Configuration System
+- **No traditional config files** - all configuration stored as kind 33334 Nostr events
+- Admin private key shown **only once** on first startup
+- Configuration changes require cryptographically signed events
+- Database path determined by generated relay pubkey
+
+### First-Time Startup Sequence
+1. Relay generates admin keypair and relay keypair
+2. Creates database file with relay pubkey as filename
+3. Stores default configuration as kind 33334 event
+4. **CRITICAL**: Admin private key displayed once and never stored on disk
+
+### Port Management
+- Default port 8888 with automatic fallback (8889, 8890, etc.)
+- Script performs port availability checking before libwebsockets binding
+- Process cleanup includes force-killing processes on port 8888
+
+### Database Schema Dependencies
+- Uses embedded SQL schema (`sql_schema.h`)
+- Schema version 4 with JSON tag storage
+- **Critical**: Event expiration filtering done at application level, not SQL level
+
+### Configuration Event Structure
+```json
+{
+  "kind": 33334,
+  "content": "C Nostr Relay Configuration",
+  "tags": [
+    ["d", "<relay_pubkey>"],
+    ["relay_description", "value"],
+    ["max_subscriptions_per_client", "25"],
+    ["pow_min_difficulty", "16"]
+  ]
+}
+```
+
+### Process Management
+```bash
+# Kill existing relay processes
+pkill -f "c_relay_"
+
+# Check running processes
+ps aux | grep c_relay_
+
+# Force kill port binding
+fuser -k 8888/tcp
+```
+
+### Cross-Compilation Specifics
+- ARM64 requires explicit dependency installation: `make install-arm64-deps`
+- Uses `aarch64-linux-gnu-gcc` with specific library paths
+- PKG_CONFIG_PATH must be set for ARM64: `/usr/lib/aarch64-linux-gnu/pkgconfig`
+
+### Testing Integration
+- Tests expect relay running on default port
+- Use `tests/quick_error_tests.sh` for validation
+- Event configuration tests: `tests/event_config_tests.sh`
+
+### SystemD Integration Considerations
+- Service runs as `c-relay` user in `/opt/c-relay`
+- Database files created in WorkingDirectory automatically
+- No environment variables needed (event-based config)
+- Resource limits: 65536 file descriptors, 4096 processes
+
+### Development vs Production Differences
+- Development: `make_and_restart_relay.sh` (default database cleanup)
+- Production: `make_and_restart_relay.sh --preserve-database`
+- Debug build requires manual gdb attachment to architecture-specific binary
+
+### Critical File Dependencies
+- `nostr_core_lib/` submodule must be initialized and built first
+- Version header auto-generated from git tags: `src/version.h`
+- Schema embedded in binary from `src/sql_schema.h`
+
+### WebSocket Protocol Specifics
+- Supports both WebSocket (Nostr protocol) and HTTP (NIP-11)
+- NIP-11 requires `Accept: application/nostr+json` header
+- CORS headers automatically added for NIP-11 compliance
+
+### Memory Management Notes
+- Persistent subscription system with thread-safe global manager
+- Per-session subscription limits enforced
+- Event filtering done at C level, not SQL level for NIP-40 expiration
+
+### Configuration Override Behavior
+- CLI port override only affects first-time startup
+- After database creation, all config comes from events
+- Database path cannot be changed after initialization
+
+## Non-Obvious Pitfalls
+
+1. **Database Lock Issues**: Script handles SQLite locking by killing existing processes first
+2. **Port Race Conditions**: Pre-check + libwebsockets binding can still fail due to timing
+3. **Key Loss**: Admin private key loss requires complete database deletion and restart
+4. **Architecture Detection**: Build system auto-detects but cross-compilation requires manual setup
+5. **Event Storage**: Ephemeral events (kind 20000-29999) accepted but not stored
+6. **Signature Validation**: All events validated with `nostr_verify_event_signature()` from nostr_core_lib
+
+## Quick Debugging Commands
+```bash
+# Check relay status
+ps aux | grep c_relay_ && netstat -tln | grep 8888
+
+# View logs
+tail -f relay.log
+
+# Test WebSocket connection
+wscat -c ws://localhost:8888
+
+# Test NIP-11 endpoint
+curl -H "Accept: application/nostr+json" http://localhost:8888
+
+# Find database files
+find . -name "*.db" -type f

-
-## 🏗️ Event-Based Configuration System
-
-### How It Works
-
-Traditional Nostr relays require configuration files, environment variables, or command line arguments. This relay uses a **revolutionary approach**:
-
-1. **First-Time Startup**: Generates cryptographically secure admin and relay keypairs
-2. **Database Creation**: Creates `<relay_pubkey>.nrdb` database file
-3. **Default Configuration**: Creates initial kind 33334 configuration event with sensible defaults
-4. **Real-Time Updates**: Administrators send new kind 33334 events to update configuration
-5. **Instant Application**: Changes are applied immediately without restart
-
-### Configuration Updates
-
-To update relay configuration, send a signed kind 33334 event:
-
-```json
-{
-  "kind": 33334,
-  "content": "C Nostr Relay Configuration",
-  "tags": [
-    ["d", "<relay_pubkey>"],
-    ["relay_description", "My awesome Nostr relay"],
-    ["max_subscriptions_per_client", "25"],
-    ["pow_min_difficulty", "16"],
-    ["nip40_expiration_enabled", "true"]
-  ],
-  "created_at": 1234567890,
-  "pubkey": "<admin_pubkey>",
-  "id": "...",
-  "sig": "..."
-}
-```
-
-Send this event to your relay via WebSocket, and changes are applied instantly.

-
-### Docker (Coming Soon)
-Docker support is planned for future releases.
-
-## 📊 Database Schema
-
-The relay uses an optimized SQLite schema (version 4) with these key features:
-
- **Event-based storage**: All Nostr events in single `events` table
- **JSON tags support**: Native JSON storage for event tags
- **Performance optimized**: Multiple indexes for fast queries
- **Subscription logging**: Optional detailed subscription analytics

- **Replaceable events**: Proper handling of replaceable/addressable events
-
-## 🛡️ Security Features
-
- **Cryptographic validation**: All configuration events cryptographically verified
- **Admin-only config**: Only authorized admin pubkey can update configuration
- **Signature verification**: Uses `nostr_verify_event_signature()` for validation
- **Event structure validation**: Complete event structure validation
- **Secure key generation**: Uses `/dev/urandom` for cryptographically secure keys
- **No secrets storage**: Admin private key never stored on disk
-
-## 🔌 Network Configuration
-
- **Default Port**: 8888 (WebSocket)
- **Protocol**: WebSocket with Nostr message format
- **Endpoints**: 
-  - `ws://localhost:8888` - WebSocket relay
-  - `http://localhost:8888` - NIP-11 relay information (HTTP GET)
-
-## 🏃‍♂️ Usage Examples
-
-### Connect with a Nostr Client
-```javascript
-const relay = new WebSocket('ws://localhost:8888');
-relay.send(JSON.stringify(["REQ", "sub1", {"kinds": [1], "limit": 10}]));
-```
-
-### Update Configuration (using `nostrtool` or similar)
-```bash
-# Create configuration event with nostrtool
-nostrtool event --kind 33334 --content "Updated config" \
-  --tag d <relay_pubkey> \
-  --tag relay_description "My updated relay" \
-  --private-key <admin_private_key>
-
-# Send to relay
-nostrtool send ws://localhost:8888 <event_json>

+# NIP-42 Authentication Implementation
+
+## Overview
+
+This relay implements NIP-42 (Authentication of clients to relays) providing granular authentication controls for event submission and subscription operations. The implementation supports both challenge-response authentication and per-connection state management.
+
+## Architecture
+
+### Core Components
+
+1. **Per-Session Authentication State** (`struct per_session_data`)
+   - `authenticated`: Boolean flag indicating authentication status
+   - `authenticated_pubkey[65]`: Hex-encoded public key of authenticated user
+   - `active_challenge[65]`: Current authentication challenge
+   - `challenge_created`: Timestamp when challenge was generated
+   - `challenge_expires`: Challenge expiration timestamp
+   - `nip42_auth_required_events`: Whether auth is required for EVENT submission
+   - `nip42_auth_required_subscriptions`: Whether auth is required for REQ operations
+   - `auth_challenge_sent`: Flag indicating if challenge has been sent
+
+2. **Challenge Management** (via `request_validator.c`)
+   - `nostr_nip42_generate_challenge()`: Generates cryptographically secure challenges
+   - `nostr_nip42_verify_auth_event()`: Validates signed authentication events
+   - Challenge storage and cleanup with expiration handling
+
+3. **WebSocket Protocol Integration**
+   - AUTH message handling in `nostr_relay_callback()`
+   - Challenge generation and transmission
+   - Authentication verification and session state updates
+
+## Configuration Options
+
+### Event-Based Configuration
+
+NIP-42 authentication is configured using kind 33334 configuration events with the following tags:
+
+| Tag | Description | Default | Values |
+|-----|-------------|---------|--------|
+| `nip42_auth_required_events` | Require auth for EVENT submission | `false` | `true`/`false` |
+| `nip42_auth_required_subscriptions` | Require auth for REQ operations | `false` | `true`/`false` |
+
+### Example Configuration Event
+
+```json
+{
+  "kind": 33334,
+  "content": "C Nostr Relay Configuration",
+  "tags": [
+    ["d", "<relay_pubkey>"],
+    ["nip42_auth_required_events", "true"],
+    ["nip42_auth_required_subscriptions", "false"],
+    ["relay_description", "Authenticated Nostr Relay"]
+  ],
+  "created_at": 1640995200,
+  "pubkey": "<admin_pubkey>",
+  "id": "<event_id>",
+  "sig": "<signature>"
+}
+```
+
+## Authentication Flow
+
+### 1. Challenge Generation
+
+When authentication is required and client is not authenticated:
+
+```
+Client -> Relay: ["EVENT", <event>] (unauthenticated)
+Relay -> Client: ["AUTH", <challenge>]
+```
+
+The challenge is a 64-character hex string generated using cryptographically secure random numbers.
+
+### 2. Authentication Response
+
+Client creates and signs an authentication event (kind 22242):
+
+```json
+{
+  "kind": 22242,
+  "content": "",
+  "tags": [
+    ["relay", "ws://relay.example.com"],
+    ["challenge", "<challenge_from_relay>"]
+  ],
+  "created_at": <current_timestamp>,
+  "pubkey": "<client_pubkey>",
+  "id": "<event_id>",
+  "sig": "<signature>"
+}
+```
+
+Client sends this event back to relay:
+
+```
+Client -> Relay: ["AUTH", <signed_auth_event>]
+```
+
+### 3. Verification and Session Update
+
+The relay:
+1. Validates the authentication event signature
+2. Verifies the challenge matches the one sent
+3. Checks challenge expiration (default: 10 minutes)
+4. Updates session state with authenticated public key
+5. Sends confirmation notice
+
+```
+Relay -> Client: ["NOTICE", "NIP-42 authentication successful"]
+```
+
+## Granular Authentication Controls
+
+### Separate Controls for Events vs Subscriptions
+
+The implementation provides separate authentication requirements:
+
+- **Event Submission**: Control whether clients must authenticate to publish events
+- **Subscription Access**: Control whether clients must authenticate to create subscriptions
+
+This allows flexible relay policies:
+- **Public Read, Authenticated Write**: `events=true, subscriptions=false`
+- **Fully Authenticated**: `events=true, subscriptions=true`
+- **Public Access**: `events=false, subscriptions=false` (default)
+- **Authenticated Read Only**: `events=false, subscriptions=true`
+
+### Per-Connection State
+
+Each WebSocket connection maintains its own authentication state:
+- Authentication persists for the lifetime of the connection
+- Challenges expire after 10 minutes
+- Session cleanup on connection close
+
+## Security Features
+
+### Challenge Security
+- 64-character hexadecimal challenges (256 bits of entropy)
+- Cryptographically secure random generation
+- Challenge expiration to prevent replay attacks
+- One-time use challenges
+
+### Event Validation
+- Complete signature verification using secp256k1
+- Event ID validation
+- Challenge-response binding verification
+- Timestamp validation with configurable tolerance
+
+### Session Management
+- Thread-safe per-session state management
+- Automatic cleanup on disconnection
+- Challenge expiration handling
+
+## Client Integration
+
+### Using nak Client
+
+```bash
+# Generate keypair
+PRIVKEY=$(nak key --gen)
+PUBKEY=$(nak key --pub $PRIVKEY)
+
+# Connect and authenticate automatically
+nak event -k 1 --content "Authenticated message" --sec $PRIVKEY --relay ws://localhost:8888
+
+# nak handles NIP-42 authentication automatically when required
+```
+
+### Manual WebSocket Integration
+
+```javascript
+const ws = new WebSocket('ws://localhost:8888');
+
+ws.onmessage = (event) => {
+  const message = JSON.parse(event.data);
+  
+  if (message[0] === 'AUTH') {
+    const challenge = message[1];
+    
+    // Create auth event (kind 22242)
+    const authEvent = {
+      kind: 22242,
+      content: "",
+      tags: [
+        ["relay", "ws://localhost:8888"],
+        ["challenge", challenge]
+      ],
+      created_at: Math.floor(Date.now() / 1000),
+      pubkey: clientPubkey,
+      // ... calculate id and signature
+    };
+    
+    // Send auth response
+    ws.send(JSON.stringify(["AUTH", authEvent]));
+  }
+};
+
+// Send event (may trigger AUTH challenge)
+ws.send(JSON.stringify(["EVENT", myEvent]));
+```
+
+## Administration
+
+### Enabling Authentication
+
+1. **Get Admin Private Key**: Extract from relay startup logs (shown once)
+2. **Create Configuration Event**: Use nak or custom tooling
+3. **Publish Configuration**: Send to relay with admin signature
+
+```bash
+# Enable auth for events only
+nak event -k 33334 \
+  --content "C Nostr Relay Configuration" \
+  --tag "d=$RELAY_PUBKEY" \
+  --tag "nip42_auth_required_events=true" \
+  --tag "nip42_auth_required_subscriptions=false" \
+  --sec $ADMIN_PRIVKEY \
+  --relay ws://localhost:8888
+```
+
+### Monitoring Authentication
+
+- Check relay logs for authentication events
+- Monitor `NOTICE` messages for auth status
+- Use `get_settings.sh` script to view current configuration
+
+```bash
+./get_settings.sh
+```
+
+## Troubleshooting
+
+### Common Issues
+
+1. **Challenge Expiration**
+   - Default: 10 minutes
+   - Client must respond within expiration window
+   - Generate new challenge for expired attempts
+
+2. **Signature Verification Failures**
+   - Verify event structure matches NIP-42 specification
+   - Check challenge value matches exactly
+   - Ensure proper secp256k1 signature generation
+
+3. **Configuration Not Applied**
+   - Verify admin private key is correct
+   - Check configuration event signature
+   - Ensure relay pubkey in 'd' tag matches relay
+
+### Debug Commands
+
+```bash
+# Check supported NIPs
+curl -H "Accept: application/nostr+json" http://localhost:8888 | jq .supported_nips
+
+# View current configuration
+nak req -k 33334 ws://localhost:8888 | jq .
+
+# Test authentication flow
+./tests/42_nip_test.sh
+```
+
+## Performance Considerations
+
+- Challenge generation: ~1ms overhead per unauthenticated connection
+- Authentication verification: ~2-5ms per auth event
+- Memory overhead: ~200 bytes per connection for auth state
+- Database impact: Configuration events cached, minimal query overhead
+
+## Integration with Other NIPs
+
+### NIP-01 (Basic Protocol)
+- AUTH messages integrated into standard WebSocket flow
+- Compatible with existing EVENT/REQ/CLOSE message handling
+
+### NIP-11 (Relay Information)
+- NIP-42 advertised in `supported_nips` array
+- Authentication requirements reflected in relay metadata
+
+### NIP-20 (Command Results)
+- OK responses include authentication-related error messages
+- NOTICE messages provide authentication status updates
+
+## Future Extensions
+
+### Potential Enhancements
+- Role-based authentication (admin, user, read-only)
+- Time-based access controls
+- Rate limiting based on authentication status
+- Integration with external authentication providers
+
+### Configuration Extensions
+- Per-kind authentication requirements
+- Whitelist/blacklist integration
+- Custom challenge expiration times
+- Authentication logging and metrics
