v0.7.24 - Fix admin API subscription issues: NIP-17 historical events and relay pubkey timing

- Restructure Dockerfile.alpine-musl for better layer caching
  * Build dependencies (secp256k1, libwebsockets) in separate cached layers
  * Copy submodules before source files to maximize cache hits
  * Reduce rebuild time from ~2-3 minutes to ~10-15 seconds for source changes
- Remove 'musl' from binary names (c_relay_static_x86_64 instead of c_relay_static_musl_x86_64)
- Enforce static binary usage in make_and_restart_relay.sh
  * Remove all fallbacks to regular make builds
  * Exit with clear error if static binary not found
  * Ensures JSON1 extension is always available
- Fix build_static.sh hanging on ldd check with timeout
- Remove sudo usage from build_static.sh (assumes docker group membership)

These changes ensure consistent builds with JSON1 support and dramatically improve
development iteration speed through intelligent Docker layer caching.

+**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)      │

+```
+
+### 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.

+# 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 in config table
+- 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 in config table
+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
+
+### Admin API Event Structure
+```json
+{
+  "kind": 23456,
+  "content": "base64_nip44_encrypted_command_array",
+  "tags": [
+    ["p", "<relay_pubkey>"]
+  ]
+}
+```
+
+**Configuration Commands** (encrypted in content):
+- `["relay_description", "My Relay"]`
+- `["max_subscriptions_per_client", "25"]`
+- `["pow_min_difficulty", "16"]`
+
+**Auth Rule Commands** (encrypted in content):
+- `["blacklist", "pubkey", "hex_pubkey_value"]`
+- `["whitelist", "pubkey", "hex_pubkey_value"]`
+
+**Query Commands** (encrypted in content):
+- `["auth_query", "all"]`
+- `["system_command", "system_status"]`
+
+### 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

-A high-performance Nostr relay implemented in C with SQLite backend, featuring a revolutionary **zero-configuration** approach using event-based configuration management.
+A high-performance Nostr relay implemented in C with SQLite backend, featuring nostr event-based management.
 
-## 🌟 Key Features
+## Supported NIPs
-
-- **🔧 Zero Configuration**: No config files or command line arguments needed
-- **🔑 Event-Based Config**: All settings stored as kind 33334 Nostr events
-- **🚀 Real-Time Updates**: Configuration changes applied instantly via WebSocket
-- **🛡️ Cryptographic Security**: Configuration events cryptographically signed and validated
-- **📊 SQLite Backend**: High-performance event storage with optimized schema
-- **🔄 Auto Key Generation**: Secure admin and relay keypairs generated on first startup
-- **💾 Database Per Relay**: Each relay instance uses `<relay_pubkey>.nrdb` database naming
-
-## 🚀 Quick Start
-
-### 1. Build the Relay
-```bash
-git clone <repository-url>
-cd c-relay
-git submodule update --init --recursive
-make
-```
-
-### 2. Start the Relay
-```bash

-```
-
-**That's it!** No configuration files, no command line arguments needed.
-
-### 3. Save Your Admin Keys (IMPORTANT!)
-On first startup, the relay will display:
-
-```
-=================================================================
-IMPORTANT: SAVE THIS ADMIN PRIVATE KEY SECURELY!
-=================================================================
-Admin Private Key: f8491814ea288260dad2ab52c09b3b037e75e83e8b24feb9bdc328423922be44
-Admin Public Key:  07fc2cdd8bdc0c60eefcc9e37e67fef88206bc84fadb894c283b006554ac687b
-
-Relay Private Key: a1b2c3d4e5f6...
-Relay Public Key:  1a2b3c4d5e6f...
-
-Database: dc9a93fd0ffba7041f6df0602e5021913a42fcaf6dbf40f43ecdc011177b4d94.nrdb
-=================================================================
-```
-
-⚠️ **Save the admin private key securely** - it's needed to update relay configuration and is only displayed once!
-
-## 📋 System Requirements
-
-- **OS**: Linux, macOS, or Windows (WSL)
-- **Dependencies**: 
-  - SQLite 3
-  - libwebsockets
-  - OpenSSL/LibreSSL
-  - libsecp256k1
-  - libcurl
-  - zlib
-
-## 🏗️ 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.
-
-### Configurable Parameters
-
-| Parameter | Description | Default |
-|-----------|-------------|---------|
-| `relay_description` | Relay description (NIP-11) | "C Nostr Relay" |
-| `relay_contact` | Admin contact info | "" |
-| `max_subscriptions_per_client` | Max subscriptions per client | "25" |

-## 🔧 Deployment
-
-### Manual Installation
-```bash
-# Build the relay
-make
-
-# Run directly
-./build/c_relay_x86
-```
-
-### SystemD Service (Recommended)
-```bash
-# Install as system service

-
-### 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
-- **Auto-cleanup**: Automatic ephemeral event cleanup
-- **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>
-```
-

-## 🆘 Troubleshooting
+## Quick Start
 
-### Common Issues
+Get your C-Relay up and running in minutes with a static binary (no dependencies required):
+
+### 1. Download Static Binary
+
+Download the latest static release from the [releases page](https://git.laantungir.net/laantungir/c-relay/releases):
 
-**Relay won't start**
 ```bash
-# Check for port conflicts
+# Static binary - works on all Linux distributions (no dependencies)
-netstat -tln | grep 8888
+wget https://git.laantungir.net/laantungir/c-relay/releases/download/v0.6.0/c-relay-v0.6.0-linux-x86_64-static
-
+chmod +x c-relay-v0.6.0-linux-x86_64-static
-# Check permissions
+mv c-relay-v0.6.0-linux-x86_64-static c-relay
-ls -la build/c_relay_x86
-
-# Check dependencies
-ldd build/c_relay_x86
 ```
 
-**Lost admin private key**
+### 2. Start the Relay
-- If you lose the admin private key, you cannot update configuration
+
-- You must delete the database file and restart (loses all events)
+Simply run the binary - no configuration files needed:
-- The relay will generate new keys on first startup
 
-**Database corruption**
 ```bash
-# Check database integrity
+./c-relay
-sqlite3 <relay_pubkey>.nrdb "PRAGMA integrity_check;"
-
-# If corrupted, remove database (loses all events)
-rm <relay_pubkey>.nrdb*
-./build/c_relay_x86  # Will create fresh database
 ```
 
-**Configuration not updating**
+On first startup, you'll see:
-- Ensure configuration events are properly signed
+- **Admin Private Key**: Save this securely! You'll need it for administration
-- Check that admin pubkey matches the one from first startup
+- **Relay Public Key**: Your relay's identity on the Nostr network
-- Verify WebSocket connection is active
+- **Port Information**: Default is 8888, or the next available port
-- Check relay logs for validation errors

+### 5. Configure Your Relay (Optional)
-- [ ] Additional NIP implementations
+
+Use the web interface or send admin commands to customize:
+- Relay name and description
+- Authentication rules (whitelist/blacklist)
+- Connection limits
+- Proof-of-work requirements
+
+**That's it!** Your relay is now running with zero configuration required. The event-based configuration system means you can adjust all settings through the web interface or admin API without editing config files.
+
+
+## Web Admin Interface
+
+C-Relay includes a **built-in web-based administration interface** accessible at `http://localhost:8888/api/`. The interface provides:
+
+- **Real-time Configuration Management**: View and edit all relay settings through a web UI
+- **Database Statistics Dashboard**: Monitor event counts, storage usage, and performance metrics
+- **Auth Rules Management**: Configure whitelist/blacklist rules for pubkeys
+- **NIP-42 Authentication**: Secure access using your Nostr identity
+- **Event-Based Updates**: All changes are applied as cryptographically signed Nostr events
+
+The web interface serves embedded static files with no external dependencies and includes proper CORS headers for browser compatibility.
+
+
+## Administrator API
+
+C-Relay uses an innovative **event-based administration system** where all configuration and management commands are sent as signed Nostr events using the admin private key generated during first startup. All admin commands use **NIP-44 encrypted command arrays** for security and compatibility.
+
+### Authentication
+
+All admin commands require signing with the admin private key displayed during first-time startup. **Save this key securely** - it cannot be recovered and is needed for all administrative operations.
+
+### Event Structure
+
+All admin commands use the same unified event structure with NIP-44 encrypted content:
+
+**Admin Command Event:**
+```json
+{
+  "id": "event_id",
+  "pubkey": "admin_public_key",
+  "created_at": 1234567890,
+  "kind": 23456,
+  "content": "AqHBUgcM7dXFYLQuDVzGwMST1G8jtWYyVvYxXhVGEu4nAb4LVw...",
+  "tags": [
+    ["p", "relay_public_key"]
+  ],
+  "sig": "event_signature"
+}
+```
+
+The `content` field contains a NIP-44 encrypted JSON array representing the command.
+
+**Admin Response Event:**
+```json
+["EVENT", "temp_sub_id", {
+  "id": "response_event_id",
+  "pubkey": "relay_public_key",
+  "created_at": 1234567890,
+  "kind": 23457,
+  "content": "BpKCVhfN8eYtRmPqSvWxZnMkL2gHjUiOp3rTyEwQaS5dFg...",
+  "tags": [
+    ["p", "admin_public_key"]
+  ],
+  "sig": "response_event_signature"
+}]
+```
+
+The `content` field contains a NIP-44 encrypted JSON response object.

+
+### Dynamic Configuration Updates
+
+C-Relay supports **dynamic configuration updates** without requiring a restart for most settings. Configuration parameters are categorized as either **dynamic** (can be updated immediately) or **restart-required** (require relay restart to take effect).
+
+**Dynamic Configuration Parameters (No Restart Required):**
+- All relay information (NIP-11) settings: `relay_name`, `relay_description`, `relay_contact`, `relay_software`, `relay_version`, `supported_nips`, `language_tags`, `relay_countries`, `posting_policy`, `payments_url`
+- Authentication settings: `auth_enabled`, `nip42_auth_required`, `nip42_auth_required_kinds`, `nip42_challenge_timeout`
+- Subscription limits: `max_subscriptions_per_client`, `max_total_subscriptions`
+- Event validation limits: `max_event_tags`, `max_content_length`, `max_message_length`
+- Proof of Work settings: `pow_min_difficulty`, `pow_mode`
+- Event expiration settings: `nip40_expiration_enabled`, `nip40_expiration_strict`, `nip40_expiration_filter`, `nip40_expiration_grace_period`
+
+**Restart-Required Configuration Parameters:**
+- Connection settings: `max_connections`, `relay_port`
+- Database and core system settings
+
+When updating configuration, the admin API response will indicate whether a restart is required for each parameter. Dynamic updates take effect immediately and are reflected in NIP-11 relay information documents without restart.
+
+### Response Format
+
+All admin commands return **signed EVENT responses** via WebSocket following standard Nostr protocol. Responses use JSON content with structured data.

+
+##  Direct Messaging Admin System
+
+In addition to the above admin API, c-relay allows the administrator to direct message the relay to get information or control some settings. As long as the administrator is signed in with any nostr client that allows sending nip-17 direct messages (DMs), they can control the relay.
+
+The is possible because the relay is a full nostr citizen with it's own private and public key, and it knows the administrator's public key.
+
+
+
+**Available DM commands**
+
+The intent is not to be strict in the formatting of the DM. So for example if the relay receives any DM from the administrator with the words "stats" or "statistics" in it, it will respond to the administrator with a reply DM with the current relay statistics.
+
+- `stats`|`statistics`: Relay statistics
+- `config`|`configuration`: Relay configuration

-**The C Nostr Relay represents the future of Nostr infrastructure - zero configuration, event-based management, and cryptographically secure administration.**

+# 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

+# C-Relay Administrator API Implementation Plan
+
+## Problem Analysis
+
+### Current Issues Identified:
+
+1. **Schema Mismatch**: Storage system (config.c) vs Validation system (request_validator.c) use different column names and values
+2. **Missing API Endpoint**: No way to clear auth_rules table for testing
+3. **Configuration Gap**: Auth rules enforcement may not be properly enabled
+4. **Documentation Gap**: Admin API commands not documented
+
+### Root Cause: Auth Rules Schema Inconsistency
+
+**Current Schema (sql_schema.h lines 140-150):**
+```sql
+CREATE TABLE auth_rules (
+    rule_type TEXT CHECK (rule_type IN ('whitelist', 'blacklist')),
+    pattern_type TEXT CHECK (pattern_type IN ('pubkey', 'hash')),  
+    pattern_value TEXT,
+    action TEXT CHECK (action IN ('allow', 'deny')),
+    active INTEGER DEFAULT 1
+);
+```
+
+**Storage Implementation (config.c):**
+- Stores: `rule_type='blacklist'`, `pattern_type='pubkey'`, `pattern_value='hex'`, `action='allow'`
+
+**Validation Implementation (request_validator.c):**
+- Queries: `rule_type='pubkey_blacklist'`, `rule_target='hex'`, `operation='event'`, `enabled=1`
+
+**MISMATCH**: Validator looks for non-existent columns and wrong rule_type values!
+
+## Proposed Solution Architecture
+
+### Phase 1: API Documentation & Standardization
+
+#### Admin API Commands (via WebSocket with admin private key)
+
+**Kind 23456: Unified Admin API (Ephemeral)**
+- Configuration management: Update relay settings, limits, authentication policies
+- Auth rules: Add/remove/query whitelist/blacklist rules
+- System commands: clear rules, status, cache management
+- **Unified Format**: All commands use NIP-44 encrypted content with `["p", "relay_pubkey"]` tags
+- **Command Types**:
+  - Configuration: `["config_key", "config_value"]`
+  - Auth rules: `["rule_type", "pattern_type", "pattern_value"]`
+  - Queries: `["auth_query", "filter"]` or `["system_command", "command_name"]`
+- **Security**: All admin commands use NIP-44 encryption for privacy and security
+
+#### Configuration Commands (using Kind 23456)
+
+1. **Update Configuration**:
+   ```json
+   {
+     "kind": 23456,
+     "content": "base64_nip44_encrypted_command_array",
+     "tags": [["p", "relay_pubkey"]]
+   }
+   ```
+   *Encrypted content contains:* `["relay_description", "My Relay"]`
+
+2. **Query System Status**:
+   ```json
+   {
+     "kind": 23456,
+     "content": "base64_nip44_encrypted_command_array",
+     "tags": [["p", "relay_pubkey"]]
+   }
+   ```
+   *Encrypted content contains:* `["system_command", "system_status"]`
+
+#### Auth Rules and System Commands (using Kind 23456)
+
+1. **Clear All Auth Rules**:
+   ```json
+   {
+     "kind": 23456,
+     "content": "base64_nip44_encrypted_command_array",
+     "tags": [["p", "relay_pubkey"]]
+   }
+   ```
+   *Encrypted content contains:* `["system_command", "clear_all_auth_rules"]`
+
+2. **Query All Auth Rules**:
+   ```json
+   {
+     "kind": 23456,
+     "content": "base64_nip44_encrypted_command_array",
+     "tags": [["p", "relay_pubkey"]]
+   }
+   ```
+   *Encrypted content contains:* `["auth_query", "all"]`
+
+3. **Add Blacklist Rule**:
+   ```json
+   {
+     "kind": 23456,
+     "content": "base64_nip44_encrypted_command_array",
+     "tags": [["p", "relay_pubkey"]]
+   }
+   ```
+   *Encrypted content contains:* `["blacklist", "pubkey", "deadbeef1234abcd..."]`
+
+### Phase 2: Auth Rules Schema Alignment
+
+#### Option A: Fix Validator to Match Schema (RECOMMENDED)
+
+**Update request_validator.c:**
+```sql
+-- OLD (broken):
+WHERE rule_type = 'pubkey_blacklist' AND rule_target = ? AND operation = ? AND enabled = 1
+
+-- NEW (correct):
+WHERE rule_type = 'blacklist' AND pattern_type = 'pubkey' AND pattern_value = ? AND active = 1
+```
+
+**Benefits:**
+- Matches actual database schema
+- Simpler rule_type values ('blacklist' vs 'pubkey_blacklist')  
+- Uses existing columns (pattern_value vs rule_target)
+- Consistent with storage implementation
+
+#### Option B: Update Schema to Match Validator (NOT RECOMMENDED)
+
+Would require changing schema, migration scripts, and storage logic.
+
+### Phase 3: Implementation Priority
+
+#### High Priority (Critical for blacklist functionality):
+1. Fix request_validator.c schema mismatch
+2. Ensure auth_required configuration is enabled
+3. Update tests to use unified ephemeral event kind (23456)
+4. Test blacklist enforcement
+
+#### Medium Priority (Enhanced Admin Features):
+1. **Implement NIP-44 Encryption Support**:
+   - Detect NIP-44 encrypted content for Kind 23456 events
+   - Parse `encrypted_tags` field from content JSON
+   - Decrypt using admin privkey and relay pubkey
+   - Process decrypted tags as normal commands
+2. Add clear_all_auth_rules system command
+3. Add auth rule query functionality (both standard and encrypted modes)
+4. Add configuration discovery (list available config keys)
+5. Enhanced error reporting in admin API
+6. Conflict resolution (same pubkey in whitelist + blacklist)
+
+#### Security Priority (NIP-44 Implementation):
+1. **Encryption Detection Logic**: Check for empty tags + encrypted_tags field
+2. **Key Pair Management**: Use admin private key + relay public key for NIP-44
+3. **Backward Compatibility**: Support both standard and encrypted modes
+4. **Error Handling**: Graceful fallback if decryption fails
+5. **Performance**: Cache decrypted results to avoid repeated decryption
+
+#### Low Priority (Documentation & Polish):
+1. Complete README.md API documentation
+2. Example usage scripts
+3. Admin client tools
+
+### Phase 4: Expected API Structure
+
+#### README.md Documentation Format:
+
+```markdown
+# C-Relay Administrator API
+
+## Authentication
+All admin commands require signing with the admin private key generated during first startup.

+  "tags": [
+    ["auth_query", "pattern", "deadbeef1234..."]
+  ]
+}
+```
+
+## System Management (Kind 23456 - Ephemeral)
+System administration commands using the same kind as auth rules.
+
+**Clear All Auth Rules:**
+```json
+{
+  "kind": 23456,
+  "content": "{\"action\":\"clear_all\",\"description\":\"Clear all auth rules\"}",

+  ]
+}
+```
+
+## Response Format
+All admin commands return JSON responses via WebSocket:
+
+**Success Response:**
+```json
+["OK", "event_id", true, "success_message"]
+```
+
+**Error Response:**  
+```json
+["OK", "event_id", false, "error_message"]
+```
+
+## Configuration Keys
+- `relay_description`: Relay description text
+- `relay_contact`: Contact information  
+- `auth_enabled`: Enable authentication system
+- `max_connections`: Maximum concurrent connections
+- `pow_min_difficulty`: Minimum proof-of-work difficulty
+- ... (full list of config keys)
+
+## Examples
+
+### Enable Authentication & Add Blacklist

+  -t "system_command=clear_all_auth_rules" \
+  --sec $ADMIN_PRIVKEY | nak event ws://localhost:8888
+```
+
+## Expected Response Formats

+
+This plan addresses the immediate blacklist issue while establishing a comprehensive admin API framework for future expansion.
+
+## NIP-44 Encryption Implementation Details
+
+### Server-Side Detection Logic
+```c
+// In admin event processing function
+bool is_encrypted_command(struct nostr_event *event) {
+    // Check if Kind 23456 with NIP-44 encrypted content
+    if (event->kind == 23456 &&
+        event->tags_count == 0) {
+        return true;
+    }
+    return false;
+}
+
+cJSON *decrypt_admin_tags(struct nostr_event *event) {
+    cJSON *content_json = cJSON_Parse(event->content);
+    if (!content_json) return NULL;
+    
+    cJSON *encrypted_tags = cJSON_GetObjectItem(content_json, "encrypted_tags");
+    if (!encrypted_tags) {
+        cJSON_Delete(content_json);
+        return NULL;
+    }
+    
+    // Decrypt using NIP-44 with admin pubkey and relay privkey
+    char *decrypted = nip44_decrypt(
+        cJSON_GetStringValue(encrypted_tags),
+        admin_pubkey,           // Shared secret with admin
+        relay_private_key       // Our private key
+    );
+    
+    cJSON *decrypted_tags = cJSON_Parse(decrypted);
+    free(decrypted);
+    cJSON_Delete(content_json);
+    
+    return decrypted_tags; // Returns tag array: [["key1", "val1"], ["key2", "val2"]]
+}
+```
+
+### Admin Event Processing Flow
+1. **Receive Event**: Kind 23456 with admin signature
+2. **Check Mode**: Empty tags = encrypted, populated tags = standard
+3. **Decrypt if Needed**: Extract and decrypt `encrypted_tags` from content
+4. **Process Commands**: Use decrypted/standard tags for command processing
+5. **Execute**: Same logic for both modes after tag extraction
+6. **Respond**: Standard response format (optionally encrypt response)
+
+### Security Benefits
+- **Command Privacy**: Admin operations invisible in event tags
+- **Replay Protection**: NIP-44 includes timestamp/randomness
+- **Key Management**: Uses existing admin/relay key pair
+- **Backward Compatible**: Standard mode still works
+- **Performance**: Only decrypt when needed (empty tags detection)
+
+### NIP-44 Library Integration
+The relay will need to integrate a NIP-44 encryption/decryption library:
+
+```c
+// Required NIP-44 functions
+char* nip44_encrypt(const char* plaintext, const char* sender_privkey, const char* recipient_pubkey);
+char* nip44_decrypt(const char* ciphertext, const char* recipient_privkey, const char* sender_pubkey);
+```
+
+### Implementation Priority (Updated)
+
+#### Phase 1: Core Infrastructure (Complete)
+- [x] Event-based admin authentication system
+- [x] Kind 23456 (Unified Admin API) processing
+- [x] Basic configuration parameter updates
+- [x] Auth rule add/remove/clear functionality
+- [x] Updated to ephemeral event kinds
+- [x] Designed NIP-44 encryption support
+
+#### Phase 2: NIP-44 Encryption Support (Next Priority)
+- [ ] **Add NIP-44 library dependency** to project
+- [ ] **Implement encryption detection logic** (`is_encrypted_command()`)
+- [ ] **Add decrypt_admin_tags() function** with NIP-44 support
+- [ ] **Update admin command processing** to handle both modes
+- [ ] **Test encrypted admin commands** end-to-end
+
+#### Phase 3: Enhanced Features
+- [ ] **Auth rule query functionality** (both standard and encrypted modes)
+- [ ] **Configuration discovery API** (list available config keys)
+- [ ] **Enhanced error messages** with encryption status
+- [ ] **Performance optimization** (caching, async decrypt)
+
+#### Phase 4: Schema Fixes (Critical)
+- [ ] **Fix request_validator.c** schema mismatch
+- [ ] **Enable blacklist enforcement** with encrypted commands
+- [ ] **Update tests** to use both standard and encrypted modes
+
+This enhanced admin API provides enterprise-grade security while maintaining ease of use for basic operations.

+
+## Initial Utilities (v0.1.0)
+
+### 1. Debug System (`debug.h`, `debug.c`)
+
+**Purpose**: Unified logging and debugging system with configurable verbosity levels.
+
+**Features**:
+- 5 debug levels: NONE, ERROR, WARN, INFO, DEBUG, TRACE
+- Timestamp formatting
+- File/line information at TRACE level
+- Macro-based API for zero-cost when disabled
+- Thread-safe (future enhancement)
+
+**API**:
+```c
+// Initialization
+void debug_init(int level);
+
+// Logging macros
+DEBUG_ERROR(format, ...);
+DEBUG_WARN(format, ...);
+DEBUG_INFO(format, ...);
+DEBUG_LOG(format, ...);
+DEBUG_TRACE(format, ...);
+
+// Global debug level
+extern debug_level_t g_debug_level;
+```
+
+**Usage Example**:
+```c
+#include <c_utils/debug.h>
+
+int main() {
+    debug_init(DEBUG_LEVEL_INFO);
+    DEBUG_INFO("Application started");
+    DEBUG_ERROR("Critical error: %s", error_msg);
+    return 0;
+}
+```
+
+### 2. Version Utilities (`version.h`, `version.c`)
+
+**Purpose**: Reusable versioning system for C projects using git tags.
+
+**Features**:
+- Automatic version extraction from git tags
+- Semantic versioning support (MAJOR.MINOR.PATCH)
+- Version comparison functions
+- Header file generation for embedding version info
+- Build number tracking
+
+**API**:
+```c
+// Version structure
+typedef struct {
+    int major;
+    int minor;
+    int patch;
+    char* git_hash;
+    char* build_date;
+} version_info_t;
+
+// Get version from git
+int version_get_from_git(version_info_t* version);
+
+// Generate version header file
+int version_generate_header(const char* output_path, const char* prefix);
+
+// Compare versions
+int version_compare(version_info_t* v1, version_info_t* v2);
+
+// Format version string
+char* version_to_string(version_info_t* version);
+```
+
+**Usage Example**:
+```c
+#include <c_utils/version.h>
+
+// In your build system:
+version_generate_header("src/version.h", "MY_APP");
+
+// In your code:
+#include "version.h"
+printf("Version: %s\n", MY_APP_VERSION);
+```
+
+**Integration with Projects**:
+```bash
+# In project Makefile
+version.h:
+	c_utils_lib/bin/generate_version src/version.h MY_PROJECT
+```
+
+## Build System
+
+### Static Library Output
+
+```
+libc_utils.a          # Static library for linking
+```
+
+### Build Targets
+
+```bash
+make                  # Build static library
+make examples         # Build examples
+make test             # Run tests
+make install          # Install to system (optional)
+make clean            # Clean build artifacts
+```
+
+### Build Script (`build.sh`)
+
+```bash
+#!/bin/bash
+# Simplified build script similar to nostr_core_lib
+
+case "$1" in
+    lib|"")
+        make
+        ;;
+    examples)
+        make examples
+        ;;
+    test)
+        make test
+        ;;
+    clean)
+        make clean
+        ;;
+    install)
+        make install
+        ;;
+    *)
+        echo "Usage: ./build.sh [lib|examples|test|clean|install]"
+        exit 1
+        ;;
+esac
+```
+
+## Versioning System Design
+
+### How It Works
+
+1. **Git Tags as Source of Truth**
+   - Version tags: `v0.1.0`, `v0.2.0`, etc.
+   - Follows semantic versioning
+
+2. **Automatic Header Generation**
+   - Script reads git tags
+   - Generates header with version macros
+   - Includes build date and git hash
+
+3. **Reusable Across Projects**
+   - Each project calls `version_generate_header()`
+   - Customizable prefix (e.g., `C_RELAY_VERSION`, `NOSTR_CORE_VERSION`)
+   - No hardcoded version numbers in source
+
+### Example Generated Header
+
+```c
+// Auto-generated by c_utils_lib version system
+#ifndef MY_PROJECT_VERSION_H
+#define MY_PROJECT_VERSION_H
+
+#define MY_PROJECT_VERSION "v0.1.0"
+#define MY_PROJECT_VERSION_MAJOR 0
+#define MY_PROJECT_VERSION_MINOR 1
+#define MY_PROJECT_VERSION_PATCH 0
+#define MY_PROJECT_GIT_HASH "a1b2c3d"
+#define MY_PROJECT_BUILD_DATE "2025-10-15"
+
+#endif
+```
+
+### Integration Pattern
+
+```makefile
+# In consuming project's Makefile
+VERSION_SCRIPT = c_utils_lib/bin/generate_version
+
+src/version.h: .git/refs/tags/*
+	$(VERSION_SCRIPT) src/version.h MY_PROJECT
+
+my_app: src/version.h src/main.c
+	$(CC) src/main.c -o my_app -Ic_utils_lib/include -Lc_utils_lib -lc_utils
+```
+
+## Future Utilities (Roadmap)

+- String trimming, splitting, joining
+- Case conversion
+- Pattern matching helpers
+
+### Memory Utilities (`memory_utils.h`)

+## Integration Guide
+
+### As Git Submodule
+
+```bash
+# In your project
+git submodule add https://github.com/yourusername/c_utils_lib.git
+git submodule update --init --recursive
+
+# Build the library
+cd c_utils_lib && ./build.sh lib && cd ..
+
+# Update your Makefile
+INCLUDES += -Ic_utils_lib/include
+LIBS += -Lc_utils_lib -lc_utils
+```
+
+### In Your Makefile
+
+```makefile
+# Check if c_utils_lib is built
+c_utils_lib/libc_utils.a:
+	cd c_utils_lib && ./build.sh lib
+
+# Link against it
+my_app: c_utils_lib/libc_utils.a src/main.c
+	$(CC) src/main.c -o my_app \
+		-Ic_utils_lib/include \
+		-Lc_utils_lib -lc_utils
+```
+
+### In Your Code
+
+```c
+// Option 1: Include everything
+#include <c_utils/c_utils.h>
+
+// Option 2: Include specific utilities
+#include <c_utils/debug.h>
+#include <c_utils/version.h>
+
+int main() {
+    debug_init(DEBUG_LEVEL_INFO);
+    DEBUG_INFO("Starting application version %s", MY_APP_VERSION);
+    return 0;
+}
+```
+

+# c_utils_lib Implementation Plan
+
+## Overview
+
+This document provides a step-by-step implementation plan for creating the `c_utils_lib` library and integrating it into the c-relay project.
+
+## Phase 1: Repository Setup & Structure
+
+### Step 1.1: Create Repository Structure
+
+**Location**: Create outside c-relay project (sibling directory)
+
+```bash
+# Create directory structure
+mkdir -p c_utils_lib/{include,src,examples,tests,docs,bin}
+cd c_utils_lib
+
+# Create subdirectories
+mkdir -p include/c_utils
+mkdir -p tests/results
+```
+
+### Step 1.2: Initialize Git Repository
+
+```bash
+cd c_utils_lib
+git init
+git branch -M main
+```
+
+### Step 1.3: Create Core Files
+
+**Files to create**:
+1. `README.md` - Main documentation
+2. `LICENSE` - MIT License
+3. `VERSION` - Version file (v0.1.0)
+4. `.gitignore` - Git ignore rules
+5. `Makefile` - Build system
+6. `build.sh` - Build script
+
+## Phase 2: Debug System Implementation
+
+### Step 2.1: Move Debug Files
+
+**Source files** (from c-relay):
+- `src/debug.c` → `c_utils_lib/src/debug.c`
+- `src/debug.h` → `c_utils_lib/include/c_utils/debug.h`
+
+**Modifications needed**:
+1. Update header guard in `debug.h`:
+   ```c
+   #ifndef C_UTILS_DEBUG_H
+   #define C_UTILS_DEBUG_H
+   ```
+
+2. No namespace changes needed (keep simple API)
+
+3. Add header documentation:
+   ```c
+   /**
+    * @file debug.h
+    * @brief Debug and logging system with configurable verbosity levels
+    * 
+    * Provides a simple, efficient logging system with 5 levels:
+    * - ERROR: Critical errors
+    * - WARN: Warnings
+    * - INFO: Informational messages
+    * - DEBUG: Debug messages
+    * - TRACE: Detailed trace with file:line info
+    */
+   ```
+
+### Step 2.2: Create Main Header
+
+**File**: `include/c_utils/c_utils.h`
+
+```c
+#ifndef C_UTILS_H
+#define C_UTILS_H
+
+/**
+ * @file c_utils.h
+ * @brief Main header for c_utils_lib - includes all utilities
+ * 
+ * Include this header to access all c_utils_lib functionality.
+ * Alternatively, include specific headers for modular usage.
+ */
+
+// Version information
+#define C_UTILS_VERSION "v0.1.0"
+#define C_UTILS_VERSION_MAJOR 0
+#define C_UTILS_VERSION_MINOR 1
+#define C_UTILS_VERSION_PATCH 0
+
+// Include all utilities
+#include "debug.h"
+#include "version.h"
+
+#endif /* C_UTILS_H */
+```
+
+## Phase 3: Version Utilities Implementation
+
+### Step 3.1: Design Version API
+
+**File**: `include/c_utils/version.h`
+
+```c
+#ifndef C_UTILS_VERSION_H
+#define C_UTILS_VERSION_H
+
+#include <time.h>
+
+/**
+ * @brief Version information structure
+ */
+typedef struct {
+    int major;
+    int minor;
+    int patch;
+    char git_hash[41];      // SHA-1 hash (40 chars + null)
+    char build_date[32];    // ISO 8601 format
+    char version_string[64]; // "vX.Y.Z" format
+} version_info_t;
+
+/**
+ * @brief Extract version from git tags
+ * @param version Output version structure
+ * @return 0 on success, -1 on error
+ */
+int version_get_from_git(version_info_t* version);
+
+/**
+ * @brief Generate version header file for a project
+ * @param output_path Path to output header file
+ * @param prefix Prefix for macros (e.g., "MY_APP")
+ * @return 0 on success, -1 on error
+ */
+int version_generate_header(const char* output_path, const char* prefix);
+
+/**
+ * @brief Compare two versions
+ * @return -1 if v1 < v2, 0 if equal, 1 if v1 > v2
+ */
+int version_compare(const version_info_t* v1, const version_info_t* v2);
+
+/**
+ * @brief Format version as string
+ * @param version Version structure
+ * @param buffer Output buffer
+ * @param buffer_size Size of output buffer
+ * @return Number of characters written
+ */
+int version_to_string(const version_info_t* version, char* buffer, size_t buffer_size);
+
+#endif /* C_UTILS_VERSION_H */
+```
+
+### Step 3.2: Implement Version Utilities
+
+**File**: `src/version.c`
+
+Key functions to implement:
+1. `version_get_from_git()` - Execute `git describe --tags` and parse
+2. `version_generate_header()` - Generate header file with macros
+3. `version_compare()` - Semantic version comparison
+4. `version_to_string()` - Format version string
+
+### Step 3.3: Create Version Generation Script
+
+**File**: `bin/generate_version`
+
+```bash
+#!/bin/bash
+# Generate version header for a project
+
+OUTPUT_FILE="$1"
+PREFIX="$2"
+
+if [ -z "$OUTPUT_FILE" ] || [ -z "$PREFIX" ]; then
+    echo "Usage: $0 <output_file> <prefix>"
+    exit 1
+fi
+
+# Get version from git
+if [ -d .git ]; then
+    VERSION=$(git describe --tags --always 2>/dev/null || echo "v0.0.0")
+    GIT_HASH=$(git rev-parse --short HEAD 2>/dev/null || echo "unknown")
+else
+    VERSION="v0.0.0"
+    GIT_HASH="unknown"
+fi
+
+# Parse version
+CLEAN_VERSION=$(echo "$VERSION" | sed 's/^v//' | cut -d- -f1)
+MAJOR=$(echo "$CLEAN_VERSION" | cut -d. -f1)
+MINOR=$(echo "$CLEAN_VERSION" | cut -d. -f2)
+PATCH=$(echo "$CLEAN_VERSION" | cut -d. -f3)
+BUILD_DATE=$(date -u +"%Y-%m-%d %H:%M:%S UTC")
+
+# Generate header
+cat > "$OUTPUT_FILE" << EOF
+/* Auto-generated by c_utils_lib version system */
+/* DO NOT EDIT - This file is automatically generated */
+
+#ifndef ${PREFIX}_VERSION_H
+#define ${PREFIX}_VERSION_H
+
+#define ${PREFIX}_VERSION "v${CLEAN_VERSION}"
+#define ${PREFIX}_VERSION_MAJOR ${MAJOR}
+#define ${PREFIX}_VERSION_MINOR ${MINOR}
+#define ${PREFIX}_VERSION_PATCH ${PATCH}
+#define ${PREFIX}_GIT_HASH "${GIT_HASH}"
+#define ${PREFIX}_BUILD_DATE "${BUILD_DATE}"
+
+#endif /* ${PREFIX}_VERSION_H */
+EOF
+
+echo "Generated $OUTPUT_FILE with version v${CLEAN_VERSION}"
+```
+
+## Phase 4: Build System
+
+### Step 4.1: Create Makefile
+
+**File**: `Makefile`
+
+```makefile
+# c_utils_lib Makefile
+
+CC = gcc
+AR = ar
+CFLAGS = -Wall -Wextra -std=c99 -O2 -g

+
+# Clean build artifacts
+clean:
+	rm -rf $(BUILD_DIR) $(LIBRARY)
+	$(MAKE) -C $(EXAMPLES_DIR) clean 2>/dev/null || true

+	@echo "  help      Show this help"
+
+.PHONY: all examples test install uninstall clean help
+```
+
+### Step 4.2: Create Build Script
+
+**File**: `build.sh`
+
+```bash
+#!/bin/bash
+# c_utils_lib build script
+
+set -e
+
+case "$1" in
+    lib|"")
+        echo "Building c_utils_lib..."
+        make
+        ;;
+    examples)
+        echo "Building examples..."
+        make examples
+        ;;
+    test)
+        echo "Running tests..."
+        make test
+        ;;
+    clean)
+        echo "Cleaning..."
+        make clean
+        ;;
+    install)
+        echo "Installing..."
+        make install
+        ;;
+    *)
+        echo "Usage: ./build.sh [lib|examples|test|clean|install]"
+        exit 1
+        ;;
+esac
+
+echo "Done!"
+```
+
+## Phase 5: Examples & Tests
+
+### Step 5.1: Create Debug Example
+
+**File**: `examples/debug_example.c`
+
+```c
+#include <c_utils/debug.h>
+
+int main() {
+    // Initialize with INFO level
+    debug_init(DEBUG_LEVEL_INFO);
+    
+    DEBUG_INFO("Application started");
+    DEBUG_WARN("This is a warning");
+    DEBUG_ERROR("This is an error");
+    
+    // This won't print (level too high)
+    DEBUG_LOG("This debug message won't show");
+    
+    // Change level to DEBUG
+    g_debug_level = DEBUG_LEVEL_DEBUG;
+    DEBUG_LOG("Now debug messages show");
+    
+    // Change to TRACE to see file:line info
+    g_debug_level = DEBUG_LEVEL_TRACE;
+    DEBUG_TRACE("Trace with file:line information");
+    
+    return 0;
+}
+```
+
+### Step 5.2: Create Version Example
+
+**File**: `examples/version_example.c`
+
+```c
+#include <c_utils/version.h>
+#include <stdio.h>
+
+int main() {
+    version_info_t version;
+    
+    // Get version from git
+    if (version_get_from_git(&version) == 0) {
+        char version_str[64];
+        version_to_string(&version, version_str, sizeof(version_str));
+        
+        printf("Version: %s\n", version_str);
+        printf("Git Hash: %s\n", version.git_hash);
+        printf("Build Date: %s\n", version.build_date);
+    }
+    
+    return 0;
+}
+```
+
+### Step 5.3: Create Test Suite
+
+**File**: `tests/test_debug.c`
+
+```c
+#include <c_utils/debug.h>
+#include <stdio.h>
+#include <string.h>
+
+int test_debug_init() {
+    debug_init(DEBUG_LEVEL_INFO);
+    return (g_debug_level == DEBUG_LEVEL_INFO) ? 0 : -1;
+}
+
+int test_debug_levels() {
+    // Test that higher levels don't print at lower settings
+    debug_init(DEBUG_LEVEL_ERROR);
+    // Would need to capture stdout to verify
+    return 0;
+}
+
+int main() {
+    int failed = 0;
+    
+    printf("Running debug tests...\n");
+    
+    if (test_debug_init() != 0) {
+        printf("FAIL: test_debug_init\n");
+        failed++;
+    } else {
+        printf("PASS: test_debug_init\n");
+    }
+    
+    if (test_debug_levels() != 0) {
+        printf("FAIL: test_debug_levels\n");
+        failed++;
+    } else {
+        printf("PASS: test_debug_levels\n");
+    }
+    
+    return failed;
+}
+```

+   #include "debug.h"
+   
+   // New
+   #include <c_utils/debug.h>
+   ```
+
+2. Remove old debug files:
+   ```bash
+   git rm src/debug.c src/debug.h
+   ```
+
+3. Update all files that use debug system:
+   - `src/main.c`
+   - `src/config.c`
+   - `src/dm_admin.c`
+   - `src/websockets.c`
+   - `src/subscriptions.c`
+   - Any other files using DEBUG_* macros
+
+### Step 7.4: Test Integration
+
+```bash
+cd c-relay
+make clean
+make
+./make_and_restart_relay.sh
+```
+
+Verify:
+- Compilation succeeds
+- Debug output works correctly
+- No functionality regressions
+
+## Phase 8: Version System Integration
+
+### Step 8.1: Update c-relay Makefile for Versioning
+
+```makefile
+# Add version generation
+src/version.h: .git/refs/tags/*
+	c_utils_lib/bin/generate_version src/version.h C_RELAY
+
+# Add dependency
+$(TARGET): src/version.h ...
+```
+
+### Step 8.2: Update c-relay to Use Generated Version
+
+Replace hardcoded version in `src/main.h` with:
+```c
+#include "version.h"
+// Use C_RELAY_VERSION instead of hardcoded VERSION
+```
+
+## Timeline Estimate
+
+- **Phase 1**: Repository Setup - 1 hour
+- **Phase 2**: Debug System - 2 hours
+- **Phase 3**: Version Utilities - 4 hours
+- **Phase 4**: Build System - 2 hours
+- **Phase 5**: Examples & Tests - 3 hours
+- **Phase 6**: Documentation - 3 hours
+- **Phase 7**: c-relay Integration - 2 hours

+# Simple Debug System Proposal
+
+## Overview
+
+A minimal debug system with 6 levels (0-5) controlled by a single `--debug-level` flag. TRACE level (5) automatically includes file:line information for ALL messages. Uses compile-time macros to ensure **zero performance impact and zero size increase** in production builds.
+
+## Debug Levels
+
+```c
+typedef enum {
+    DEBUG_LEVEL_NONE = 0,      // Production: no debug output
+    DEBUG_LEVEL_ERROR = 1,     // Errors only
+    DEBUG_LEVEL_WARN = 2,      // Errors + Warnings
+    DEBUG_LEVEL_INFO = 3,      // Errors + Warnings + Info
+    DEBUG_LEVEL_DEBUG = 4,     // All above + Debug messages
+    DEBUG_LEVEL_TRACE = 5      // All above + Trace (very verbose)
+} debug_level_t;
+```
+
+## Usage
+
+```bash
+# Production (default - no debug output)
+./c_relay_x86
+
+# Show errors only
+./c_relay_x86 --debug-level=1
+
+# Show errors and warnings
+./c_relay_x86 --debug-level=2
+
+# Show errors, warnings, and info (recommended for development)
+./c_relay_x86 --debug-level=3
+
+# Show all debug messages
+./c_relay_x86 --debug-level=4
+
+# Show everything including trace with file:line (very verbose)
+./c_relay_x86 --debug-level=5
+```
+
+## Implementation
+
+### 1. Header File (`src/debug.h`)
+
+```c
+#ifndef DEBUG_H
+#define DEBUG_H
+
+#include <stdio.h>
+#include <time.h>
+
+// Debug levels
+typedef enum {
+    DEBUG_LEVEL_NONE = 0,
+    DEBUG_LEVEL_ERROR = 1,
+    DEBUG_LEVEL_WARN = 2,
+    DEBUG_LEVEL_INFO = 3,
+    DEBUG_LEVEL_DEBUG = 4,
+    DEBUG_LEVEL_TRACE = 5
+} debug_level_t;
+
+// Global debug level (set at runtime via CLI)
+extern debug_level_t g_debug_level;
+
+// Initialize debug system
+void debug_init(int level);
+
+// Core logging function
+void debug_log(debug_level_t level, const char* file, int line, const char* format, ...);
+
+// Convenience macros that check level before calling
+// Note: TRACE level (5) and above include file:line information for ALL messages
+#define DEBUG_ERROR(...) \
+    do { if (g_debug_level >= DEBUG_LEVEL_ERROR) debug_log(DEBUG_LEVEL_ERROR, __FILE__, __LINE__, __VA_ARGS__); } while(0)
+
+#define DEBUG_WARN(...) \
+    do { if (g_debug_level >= DEBUG_LEVEL_WARN) debug_log(DEBUG_LEVEL_WARN, __FILE__, __LINE__, __VA_ARGS__); } while(0)
+
+#define DEBUG_INFO(...) \
+    do { if (g_debug_level >= DEBUG_LEVEL_INFO) debug_log(DEBUG_LEVEL_INFO, __FILE__, __LINE__, __VA_ARGS__); } while(0)
+
+#define DEBUG_LOG(...) \
+    do { if (g_debug_level >= DEBUG_LEVEL_DEBUG) debug_log(DEBUG_LEVEL_DEBUG, __FILE__, __LINE__, __VA_ARGS__); } while(0)
+
+#define DEBUG_TRACE(...) \
+    do { if (g_debug_level >= DEBUG_LEVEL_TRACE) debug_log(DEBUG_LEVEL_TRACE, __FILE__, __LINE__, __VA_ARGS__); } while(0)
+
+#endif /* DEBUG_H */
+```
+
+### 2. Implementation File (`src/debug.c`)
+
+```c
+#include "debug.h"
+#include <stdarg.h>
+#include <string.h>
+
+// Global debug level (default: no debug output)
+debug_level_t g_debug_level = DEBUG_LEVEL_NONE;
+
+void debug_init(int level) {
+    if (level < 0) level = 0;
+    if (level > 5) level = 5;
+    g_debug_level = (debug_level_t)level;
+}
+
+void debug_log(debug_level_t level, const char* file, int line, const char* format, ...) {
+    // Get timestamp
+    time_t now = time(NULL);
+    struct tm* tm_info = localtime(&now);
+    char timestamp[32];
+    strftime(timestamp, sizeof(timestamp), "%Y-%m-%d %H:%M:%S", tm_info);
+    
+    // Get level string
+    const char* level_str = "UNKNOWN";
+    switch (level) {
+        case DEBUG_LEVEL_ERROR: level_str = "ERROR"; break;
+        case DEBUG_LEVEL_WARN:  level_str = "WARN "; break;
+        case DEBUG_LEVEL_INFO:  level_str = "INFO "; break;
+        case DEBUG_LEVEL_DEBUG: level_str = "DEBUG"; break;
+        case DEBUG_LEVEL_TRACE: level_str = "TRACE"; break;
+        default: break;
+    }
+    
+    // Print prefix with timestamp and level
+    printf("[%s] [%s] ", timestamp, level_str);
+    
+    // Print source location when debug level is TRACE (5) or higher
+    if (file && g_debug_level >= DEBUG_LEVEL_TRACE) {
+        // Extract just the filename (not full path)
+        const char* filename = strrchr(file, '/');
+        filename = filename ? filename + 1 : file;
+        printf("[%s:%d] ", filename, line);
+    }
+    
+    // Print message
+    va_list args;
+    va_start(args, format);
+    vprintf(format, args);
+    va_end(args);
+    
+    printf("\n");
+    fflush(stdout);
+}
+```
+
+### 3. CLI Argument Parsing (add to `src/main.c`)
+
+```c
+// In main() function, add to argument parsing:
+
+int debug_level = 0;  // Default: no debug output
+
+for (int i = 1; i < argc; i++) {
+    if (strncmp(argv[i], "--debug-level=", 14) == 0) {
+        debug_level = atoi(argv[i] + 14);
+        if (debug_level < 0) debug_level = 0;
+        if (debug_level > 5) debug_level = 5;
+    }
+    // ... other arguments ...
+}
+
+// Initialize debug system
+debug_init(debug_level);
+```
+
+### 4. Update Makefile
+
+```makefile
+# Add debug.c to source files
+MAIN_SRC = src/main.c src/config.c src/debug.c src/dm_admin.c src/request_validator.c ...
+```
+
+## Migration Strategy
+
+### Keep Existing Functions
+
+The existing `log_*` functions can remain as wrappers:
+
+```c
+// src/main.c - Update existing functions
+// Note: These don't include file:line since they're wrappers
+void log_info(const char* message) {
+    if (g_debug_level >= DEBUG_LEVEL_INFO) {
+        debug_log(DEBUG_LEVEL_INFO, NULL, 0, "%s", message);
+    }
+}
+
+void log_error(const char* message) {
+    if (g_debug_level >= DEBUG_LEVEL_ERROR) {
+        debug_log(DEBUG_LEVEL_ERROR, NULL, 0, "%s", message);
+    }
+}
+
+void log_warning(const char* message) {
+    if (g_debug_level >= DEBUG_LEVEL_WARN) {
+        debug_log(DEBUG_LEVEL_WARN, NULL, 0, "%s", message);
+    }
+}
+
+void log_success(const char* message) {
+    if (g_debug_level >= DEBUG_LEVEL_INFO) {
+        debug_log(DEBUG_LEVEL_INFO, NULL, 0, "✓ %s", message);
+    }
+}
+```
+
+### Gradual Migration
+
+Gradually replace log calls with debug macros:
+
+```c
+// Before:
+log_info("Starting WebSocket relay server");
+
+// After:
+DEBUG_INFO("Starting WebSocket relay server");
+
+// Before:
+log_error("Failed to initialize database");
+
+// After:
+DEBUG_ERROR("Failed to initialize database");
+```
+
+### Add New Debug Levels
+
+Add debug and trace messages where needed:
+
+```c
+// Detailed debugging
+DEBUG_LOG("Processing subscription: %s", sub_id);
+DEBUG_LOG("Filter count: %d", filter_count);
+
+// Very verbose tracing
+DEBUG_TRACE("Entering handle_req_message()");
+DEBUG_TRACE("Subscription ID validated: %s", sub_id);
+DEBUG_TRACE("Exiting handle_req_message()");
+```
+## Manual Guards for Expensive Operations
+
+### The Problem
+
+Debug macros use **runtime checks**, which means function arguments are always evaluated:
+
+```c
+// ❌ BAD: Database query executes even when debug level is 0
+DEBUG_LOG("Count: %d", expensive_database_query());
+```
+
+The `expensive_database_query()` will **always execute** because function arguments are evaluated before the `if` check inside the macro.
+
+### The Solution: Manual Guards
+
+For expensive operations (database queries, file I/O, complex calculations), use manual guards:
+
+```c
+// ✅ GOOD: Query only executes when debugging is enabled
+if (g_debug_level >= DEBUG_LEVEL_DEBUG) {
+    int count = expensive_database_query();
+    DEBUG_LOG("Count: %d", count);
+}
+```
+
+### Standardized Comment Format
+
+To make temporary debug guards easy to find and remove, use this standardized format:
+
+```c
+// DEBUG_GUARD_START
+if (g_debug_level >= DEBUG_LEVEL_DEBUG) {
+    // Expensive operation here
+    sqlite3_stmt* stmt;
+    const char* sql = "SELECT COUNT(*) FROM events";
+    int count = 0;
+    if (sqlite3_prepare_v2(g_db, sql, -1, &stmt, NULL) == SQLITE_OK) {
+        if (sqlite3_step(stmt) == SQLITE_ROW) {
+            count = sqlite3_column_int(stmt, 0);
+        }
+        sqlite3_finalize(stmt);
+    }
+    DEBUG_LOG("Event count: %d", count);
+}
+// DEBUG_GUARD_END
+```
+
+### Easy Removal
+
+When you're done debugging, find and remove all temporary guards:
+
+```bash
+# Find all debug guards
+grep -n "DEBUG_GUARD_START" src/*.c
+
+# Remove guards with sed (between START and END markers)
+sed -i '/DEBUG_GUARD_START/,/DEBUG_GUARD_END/d' src/config.c
+```
+
+Or use a simple script:
+
+```bash
+#!/bin/bash
+# remove_debug_guards.sh
+for file in src/*.c; do
+    sed -i '/DEBUG_GUARD_START/,/DEBUG_GUARD_END/d' "$file"
+    echo "Removed debug guards from $file"
+done
+```
+
+### When to Use Manual Guards
+
+Use manual guards for:
+- ✅ Database queries
+- ✅ File I/O operations
+- ✅ Network requests
+- ✅ Complex calculations
+- ✅ Memory allocations for debug data
+- ✅ String formatting with multiple operations
+
+Don't need guards for:
+- ❌ Simple variable access
+- ❌ Basic arithmetic
+- ❌ String literals
+- ❌ Function calls that are already cheap
+
+### Example: Database Query Guard
+
+```c
+// DEBUG_GUARD_START
+if (g_debug_level >= DEBUG_LEVEL_DEBUG) {
+    sqlite3_stmt* count_stmt;
+    const char* count_sql = "SELECT COUNT(*) FROM config";
+    int config_count = 0;
+    
+    if (sqlite3_prepare_v2(g_db, count_sql, -1, &count_stmt, NULL) == SQLITE_OK) {
+        if (sqlite3_step(count_stmt) == SQLITE_ROW) {
+            config_count = sqlite3_column_int(count_stmt, 0);
+        }
+        sqlite3_finalize(count_stmt);
+    }
+    
+    DEBUG_LOG("Config table has %d rows", config_count);
+}
+// DEBUG_GUARD_END
+```
+
+### Example: Complex String Formatting Guard
+
+```c
+// DEBUG_GUARD_START
+if (g_debug_level >= DEBUG_LEVEL_TRACE) {
+    char filter_str[1024] = {0};
+    int offset = 0;
+    
+    for (int i = 0; i < filter_count && offset < sizeof(filter_str) - 1; i++) {
+        offset += snprintf(filter_str + offset, sizeof(filter_str) - offset,
+                          "Filter %d: kind=%d, author=%s; ",
+                          i, filters[i].kind, filters[i].author);
+    }
+    
+    DEBUG_TRACE("Processing filters: %s", filter_str);
+}
+// DEBUG_GUARD_END
+```
+
+### Alternative: Compile-Time Guards
+
+For permanent debug code that should be completely removed in production builds, use compile-time guards:
+
+```c
+#ifdef ENABLE_DEBUG_CODE
+    // This code is completely removed when ENABLE_DEBUG_CODE is not defined
+    int count = expensive_database_query();
+    DEBUG_LOG("Count: %d", count);
+#endif
+```
+
+Build with debug code:
+```bash
+make CFLAGS="-DENABLE_DEBUG_CODE"
+```
+
+Build without debug code (production):
+```bash
+make  # No debug code compiled in
+```
+
+### Best Practices
+
+1. **Always use standardized markers** (`DEBUG_GUARD_START`/`DEBUG_GUARD_END`) for temporary guards
+2. **Add a comment** explaining what you're debugging
+3. **Remove guards** when debugging is complete
+4. **Use compile-time guards** for permanent debug infrastructure
+5. **Keep guards simple** - one guard per logical debug operation
+
+
+## Performance Impact
+
+### Runtime Check
+
+The macros include a runtime check:
+
+```c
+#define DEBUG_INFO(...) \
+    do { if (g_debug_level >= DEBUG_LEVEL_INFO) debug_log(DEBUG_LEVEL_INFO, NULL, 0, __VA_ARGS__); } while(0)
+```
+
+**Cost**: One integer comparison per debug statement (~1 CPU cycle)
+
+**Impact**: Negligible - the comparison is faster than a function call
+
+**Note**: Only `DEBUG_TRACE` includes `__FILE__` and `__LINE__`, which are compile-time constants with no runtime overhead.
+
+### When Debug Level is 0 (Production)
+
+```c
+// With g_debug_level = 0:
+DEBUG_INFO("Starting server");
+
+// Becomes:
+if (0 >= 3) debug_log(...);  // Never executes
+
+// Compiler optimizes to:
+// (nothing - branch is eliminated)
+```
+
+**Result**: Modern compilers (gcc -O2 or higher) will completely eliminate the dead code branch.
+
+### Size Impact
+
+**Test Case**: 100 debug statements in code
+
+**Without optimization** (`-O0`):
+- Binary size increase: ~2KB (branch instructions)
+- Runtime cost: 100 comparisons per execution
+
+**With optimization** (`-O2` or `-O3`):
+- Binary size increase: **0 bytes** (dead code eliminated when g_debug_level = 0)
+- Runtime cost: **0 cycles** (branches removed by compiler)
+
+### Verification
+
+You can verify the optimization with:
+
+```bash
+# Compile with optimization
+gcc -O2 -c debug_test.c -o debug_test.o
+
+# Disassemble and check
+objdump -d debug_test.o | grep -A 10 "debug_log"
+```
+
+When `g_debug_level = 0` (constant), you'll see the compiler has removed all debug calls.
+

+```
+
+## Implementation Steps
+
+### Step 1: Create Files (5 minutes)
+
+1. Create `src/debug.h` with the header code above
+2. Create `src/debug.c` with the implementation code above
+3. Update `Makefile` to include `src/debug.c` in `MAIN_SRC`
+
+### Step 2: Add CLI Parsing (5 minutes)
+
+Add `--debug-level` argument parsing to `main()` in `src/main.c`
+
+### Step 3: Update Existing Functions (5 minutes)
+
+Update the existing `log_*` functions to use the new debug macros
+
+### Step 4: Test (5 minutes)
+
+```bash
+# Build
+make clean && make
+
+# Test different levels
+./build/c_relay_x86                    # No output
+./build/c_relay_x86 --debug-level=1    # Errors only
+./build/c_relay_x86 --debug-level=3    # Info + warnings + errors
+./build/c_relay_x86 --debug-level=4    # All debug messages
+./build/c_relay_x86 --debug-level=5    # Everything with file:line on TRACE
+```
+
+### Step 5: Gradual Migration (Ongoing)
+
+As you work on different parts of the code, replace `log_*` calls with `DEBUG_*` macros and add new debug/trace statements where helpful.
+
+## Benefits
+
+✅ **Simple**: Single flag, 6 levels, easy to understand  
+✅ **Zero Overhead**: Compiler optimizes away unused debug code  
+✅ **Zero Size Impact**: No binary size increase in production  
+✅ **Backward Compatible**: Existing `log_*` functions still work  
+✅ **Easy Migration**: Gradual replacement of log calls  
+✅ **Flexible**: Can add detailed debugging without affecting production  
+
+## Total Implementation Time
+
+**~20 minutes** for basic implementation  
+**Ongoing** for gradual migration of existing log calls
+
+## Recommendation
+
+This is the simplest possible debug system that provides:
+- Multiple debug levels for different verbosity
+- Zero performance impact in production
+- Zero binary size increase
+- Easy to use and understand
+- Backward compatible with existing code
+
+Start with the basic implementation, test it, then gradually migrate existing log calls and add new debug statements as needed.

-```c
-int startup_existing_relay(const char* relay_pubkey) {
-    // 1. Open database
-    if (init_database_with_pubkey(relay_pubkey) != 0) {
-        return -1;
-    }
-    
-    // 2. Load configuration event from database
-    cJSON* config_event = load_config_event_from_database(relay_pubkey);
-    if (!config_event) {
-        log_error("No configuration event found in database");
-        return -1;
-    }
-    
-    // 3. Apply all configuration from event
-    if (apply_configuration_from_event(config_event) != 0) {
-        return -1;
-    }
-    
-    // 4. Continue with normal startup
-    return start_relay_services();
-}
-```
-
-## Implementation Order - PROGRESS STATUS
-
-### Step 1: Core Infrastructure ✅ COMPLETED
-1. ✅ Implement database naming with relay pubkey
-2. ✅ Add key generation functions using `nostr_core_lib`
-3. ✅ Create configuration event storage/retrieval functions
-4. ✅ Test basic event creation and storage
-
-### Step 2: Event Processing Integration ✅ MOSTLY COMPLETED
-1. ✅ Add kind 33334 event detection to event processing loop
-2. ✅ Implement configuration event validation
-3. ⚠️ Create configuration application handlers (basic access implemented, runtime handlers pending)
-4. ⏳ Test real-time configuration updates (infrastructure ready)
-
-### Step 3: First-Time Startup ✅ COMPLETED
-1. ✅ Implement first-time startup detection
-2. ✅ Add automatic key generation and database creation
-3. ✅ Create default configuration event generation
-4. ✅ Test complete first-time startup flow
-
-### Step 4: Legacy Removal ⚠️ MOSTLY COMPLETED
-1. ✅ Remove command line argument parsing

-
-### Step 5: Testing and Validation ⚠️ PARTIALLY COMPLETED
-1. ✅ Test complete startup flow (first time and existing)
-2. ⏳ Test configuration updates via events (infrastructure ready)
-3. ⚠️ Test error handling and recovery (basic error handling implemented)
-4. ⏳ Performance testing and optimization (pending)
-
-## Migration Strategy
-
-### For Existing Installations
-Since the new system uses a completely different approach:
-
-1. **No Automatic Migration**: The new system starts fresh
-2. **Manual Migration**: Users can manually copy configuration values
-3. **Documentation**: Provide clear migration instructions
-4. **Coexistence**: Old and new systems use different database names
-
-### Migration Steps for Users
-1. Stop existing relay
-2. Note current configuration values
-3. Start new relay (generates keys and new database)
-4. Create kind 33334 event with desired configuration using admin private key
-5. Send event to relay to update configuration
-
-## Testing Requirements
-
-### Unit Tests
-- Key generation functions
-- Configuration event creation and validation
-- Database naming logic
-- Configuration application handlers
-
-### Integration Tests  
-- Complete first-time startup flow
-- Configuration update via events
-- Error handling scenarios
-- Database operations
-
-### Performance Tests
-- Startup time comparison
-- Configuration update response time
-- Memory usage analysis
-
-## Security Considerations
-
-1. **Admin Private Key**: Never stored, only printed once
-2. **Event Validation**: All configuration events must be signed by admin
-3. **Database Security**: Relay database contains relay private key
-4. **Key Generation**: Use `nostr_core_lib` for cryptographically secure generation
-
-## Files to Modify
-
-### Major Changes
-- `src/main.c` - Startup logic, event processing, argument removal
-- `src/config.c` - Complete rewrite for event-based configuration
-- `src/config.h` - Update function signatures and structures
-- `src/sql_schema.h` - Remove config tables
-
-### Minor Changes
-- `Makefile` - Remove any config file generation
-- `systemd/` - Update service files if needed
-- Documentation updates
-
-## Backwards Compatibility
-
-**Breaking Changes:**
-- Command line arguments removed (except --help, --version)
-- Configuration files no longer used
-- Database naming scheme changed
-- Configuration table removed
-
-**Migration Required:** This is a breaking change that requires manual migration for existing installations.
-
-## Success Criteria - CURRENT STATUS
-
-1. ✅ **Zero Command Line Arguments**: Relay starts with just `./c-relay`
-2. ✅ **Automatic First-Time Setup**: Generates keys and database automatically
-3. ⚠️ **Real-Time Configuration**: Infrastructure ready, handlers need completion
-4. ✅ **Single Database File**: All configuration and data in one `.nrdb` file
-5. ⚠️ **Admin Control**: Event processing implemented, signature validation ready
-6. ⚠️ **Clean Codebase**: Most legacy code removed, database tables cleanup pending
-
-## Risk Mitigation
-
-1. **Backup Strategy**: Document manual backup procedures for relay database
-2. **Key Loss Recovery**: Document recovery procedures if admin key is lost
-3. **Testing Coverage**: Comprehensive test suite before deployment
-4. **Rollback Plan**: Keep old version available during transition period
-5. **Documentation**: Comprehensive user and developer documentation
-
-This implementation plan provides a clear path from the current system to the new event-based configuration architecture while maintaining security and reliability.

+# MUSL Static Binary Build Guide
+
+## Overview
+
+This guide explains how to build truly portable MUSL-based static binaries of c-relay using Alpine Linux Docker containers. These binaries have **zero runtime dependencies** and work on any Linux distribution.
+
+## Why MUSL?
+
+### MUSL vs glibc Static Binaries
+
+**MUSL Advantages:**
+- **Truly Static**: No hidden dependencies on system libraries
+- **Smaller Size**: ~7.6MB vs ~12MB+ for glibc static builds
+- **Better Portability**: Works on ANY Linux distribution without modification
+- **Cleaner Linking**: No glibc-specific extensions or fortified functions
+- **Simpler Deployment**: Single binary, no library compatibility issues
+
+**glibc Limitations:**
+- Static builds still require dynamic loading for NSS (Name Service Switch)
+- Fortified functions (`__*_chk`) don't exist in MUSL
+- Larger binary size due to glibc's complexity
+- May have compatibility issues across different glibc versions
+
+## Build Process
+
+### Prerequisites
+
+- Docker installed and running
+- Sufficient disk space (~2GB for Docker layers)
+- Internet connection (for downloading dependencies)
+
+### Quick Start
+
+```bash
+# Build MUSL static binary
+./build_static.sh
+
+# The binary will be created at:
+# build/c_relay_static_musl_x86_64  (on x86_64)
+# build/c_relay_static_musl_arm64   (on ARM64)
+```
+
+### What Happens During Build
+
+1. **Alpine Linux Base**: Uses Alpine 3.19 with native MUSL support
+2. **Static Dependencies**: Builds all dependencies with static linking:
+   - libsecp256k1 (Bitcoin cryptography)
+   - libwebsockets (WebSocket server)
+   - OpenSSL (TLS/crypto)
+   - SQLite (database)
+   - curl (HTTP client)
+   - zlib (compression)
+
+3. **nostr_core_lib**: Builds with MUSL-compatible flags:
+   - Disables glibc fortification (`-U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=0`)
+   - Includes required NIPs: 001, 006, 013, 017, 019, 044, 059
+   - Produces static library (~316KB)
+
+4. **c-relay Compilation**: Links everything statically:
+   - All source files compiled with `-static` flag
+   - Fortification disabled to avoid `__*_chk` symbols
+   - Results in ~7.6MB stripped binary
+
+5. **Verification**: Confirms binary is truly static:
+   - `ldd` shows "not a dynamic executable"
+   - `file` shows "statically linked"
+   - Binary executes successfully
+
+## Technical Details
+
+### Dockerfile Structure
+
+The build uses a multi-stage Dockerfile (`Dockerfile.alpine-musl`):
+
+```dockerfile
+# Stage 1: Builder (Alpine Linux)
+FROM alpine:3.19 AS builder
+- Install build tools and static libraries
+- Build dependencies from source
+- Compile nostr_core_lib with MUSL flags
+- Compile c-relay with full static linking
+- Strip binary to reduce size
+
+# Stage 2: Output (scratch)
+FROM scratch AS output
+- Contains only the final binary
+```
+
+### Key Compilation Flags
+
+**For nostr_core_lib:**
+```bash
+CFLAGS="-U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=0 -Wall -Wextra -std=c99 -fPIC -O2"
+```
+
+**For c-relay:**
+```bash
+gcc -static -O2 -Wall -Wextra -std=c99 \
+    -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=0 \
+    [source files] \
+    -lwebsockets -lssl -lcrypto -lsqlite3 -lsecp256k1 \
+    -lcurl -lz -lpthread -lm -ldl
+```
+
+### Fortification Issue
+
+**Problem**: GCC's `-O2` optimization enables fortification by default, replacing standard functions with `__*_chk` variants (e.g., `__snprintf_chk`, `__fprintf_chk`). These are glibc-specific and don't exist in MUSL.
+
+**Solution**: Explicitly disable fortification with:
+- `-U_FORTIFY_SOURCE` (undefine any existing definition)
+- `-D_FORTIFY_SOURCE=0` (set to 0)
+
+This must be applied to **both** nostr_core_lib and c-relay compilation.
+
+### NIP Dependencies
+
+The build includes these NIPs in nostr_core_lib:
+- **NIP-001**: Basic protocol (event creation, signing)
+- **NIP-006**: Key derivation from mnemonic
+- **NIP-013**: Proof of Work validation
+- **NIP-017**: Private Direct Messages
+- **NIP-019**: Bech32 encoding (nsec/npub)
+- **NIP-044**: Modern encryption
+- **NIP-059**: Gift Wrap (required by NIP-017)
+
+## Verification
+
+### Check Binary Type
+
+```bash
+# Should show "statically linked"
+file build/c_relay_static_musl_x86_64
+
+# Should show "not a dynamic executable"
+ldd build/c_relay_static_musl_x86_64
+
+# Check size (should be ~7.6MB)
+ls -lh build/c_relay_static_musl_x86_64
+```
+
+### Test Execution
+
+```bash
+# Show help
+./build/c_relay_static_musl_x86_64 --help
+
+# Show version
+./build/c_relay_static_musl_x86_64 --version
+
+# Run relay
+./build/c_relay_static_musl_x86_64 --port 8888
+```
+
+### Cross-Distribution Testing
+
+Test the binary on different distributions to verify portability:
+
+```bash
+# Alpine Linux
+docker run --rm -v $(pwd)/build:/app alpine:latest /app/c_relay_static_musl_x86_64 --version
+
+# Ubuntu
+docker run --rm -v $(pwd)/build:/app ubuntu:latest /app/c_relay_static_musl_x86_64 --version
+
+# Debian
+docker run --rm -v $(pwd)/build:/app debian:latest /app/c_relay_static_musl_x86_64 --version
+
+# CentOS
+docker run --rm -v $(pwd)/build:/app centos:latest /app/c_relay_static_musl_x86_64 --version
+```
+
+## Troubleshooting
+
+### Docker Permission Denied
+
+**Problem**: `permission denied while trying to connect to the Docker daemon socket`
+
+**Solution**: Add user to docker group:
+```bash
+sudo usermod -aG docker $USER
+newgrp docker  # Or logout and login again
+```
+
+### Build Fails with Fortification Errors
+
+**Problem**: `undefined reference to '__snprintf_chk'` or `'__fprintf_chk'`
+
+**Solution**: Ensure fortification is disabled in both:
+1. nostr_core_lib build.sh (line 534)
+2. c-relay compilation flags in Dockerfile
+
+### Binary Won't Execute
+
+**Problem**: Binary fails to run on target system
+
+**Checks**:
+1. Verify it's truly static: `ldd binary` should show "not a dynamic executable"
+2. Check architecture matches: `file binary` should show correct arch
+3. Ensure execute permissions: `chmod +x binary`
+
+### Missing NIP Functions
+
+**Problem**: `undefined reference to 'nostr_nip*'` during linking
+
+**Solution**: Add missing NIPs to the build command:
+```bash
+./build.sh --nips=1,6,13,17,19,44,59
+```
+
+## Deployment
+
+### Single Binary Deployment
+
+```bash
+# Copy binary to server
+scp build/c_relay_static_musl_x86_64 user@server:/opt/c-relay/
+
+# Run on server (no dependencies needed!)
+ssh user@server
+cd /opt/c-relay
+./c_relay_static_musl_x86_64 --port 8888
+```
+
+### SystemD Service
+
+```ini
+[Unit]
+Description=C-Relay Nostr Relay (MUSL Static)
+After=network.target
+
+[Service]
+Type=simple
+User=c-relay
+WorkingDirectory=/opt/c-relay
+ExecStart=/opt/c-relay/c_relay_static_musl_x86_64
+Restart=always
+RestartSec=5
+
+[Install]
+WantedBy=multi-user.target
+```
+
+## Performance Comparison
+
+| Metric | MUSL Static | glibc Static | glibc Dynamic |
+|--------|-------------|--------------|---------------|
+| Binary Size | 7.6 MB | 12+ MB | 2-3 MB |
+| Startup Time | ~50ms | ~60ms | ~40ms |
+| Memory Usage | Similar | Similar | Similar |
+| Portability | ✓ Any Linux | ⚠ glibc only | ✗ Requires libs |
+| Dependencies | None | NSS libs | Many libs |
+
+## Best Practices
+
+1. **Always verify** the binary is truly static before deployment
+2. **Test on multiple distributions** to ensure portability
+3. **Keep Docker images updated** for security patches
+4. **Document the build date** and commit hash for reproducibility
+5. **Store binaries** with architecture in filename (e.g., `_x86_64`, `_arm64`)

-# Startup Configuration Design Analysis
-
-## Review of startup_config_design.md
-
-### Key Design Principles Identified
-
-1. **Zero Command Line Arguments**: Complete elimination of CLI arguments for true "quick start"
-2. **Event-Based Configuration**: Configuration stored as Nostr event (kind 33334) in events table
-3. **Self-Contained Database**: Database named after relay pubkey (`<pubkey>.nrdb`)
-4. **First-Time Setup**: Automatic key generation and initial configuration creation
-5. **Configuration Consistency**: Always read from event, never from hardcoded defaults
-
-### Implementation Gaps and Specifications Needed
-
-#### 1. Key Generation Process
-**Specification:**
-```
-First Startup Key Generation:
-1. Generate all keys on first startup (admin private/public, relay private/public)
-2. Use nostr_core_lib for key generation entropy
-3. Keys are encoded in hex format
-4. Print admin private key to stdout for user to save (never stored)
-5. Store admin public key, relay private key, and relay public key in configuration event
-6. Admin can later change the 33334 event to alter stored keys
-```
-
-#### 2. Database Naming and Location
-**Specification:**
-```
-Database Naming:
-1. Database is named using relay pubkey: ./<relay_pubkey>.nrdb
-2. Database path structure: ./<relay_pubkey>.nrdb
-3. If database creation fails, program quits (can't run without database)
-4. c_nostr_relay.db should never exist in new system
-```
-
-#### 3. Configuration Event Structure (Kind 33334)
-**Specification:**
-```
-Event Structure:
-- Kind: 33334 (parameterized replaceable event)
-- Event validation: Use nostr_core_lib to validate event
-- Event content field: "C Nostr Relay Configuration" (descriptive text)
-- Configuration update mechanism: TBD
-- Complete tag structure provided in configuration section below
-```
-
-
-
-#### 4. Configuration Change Monitoring
-**Configuration Monitoring System:**
-```
-Every event that is received is checked to see if it is a kind 33334 event from the admin pubkey.
-If so, it is processed as a configuration update.
-```
-
-#### 5. Error Handling and Recovery
-**Specification:**
-```
-Error Recovery Priority:
-1. Try to load latest valid config event
-2. Generate new default configuration event if none exists
-3. Exit with error if all recovery attempts fail
-
-Note: There is only ever one configuration event (parameterized replaceable event),
-so no fallback to previous versions.
-```
-
-### Design Clarifications
-
-**Key Management:**
-- Admin private key is never stored, only printed once at first startup
-- Single admin system (no multi-admin support)
-- No key rotation support
-
-**Configuration Management:**
-- No configuration versioning/timestamping
-- No automatic backup of configuration events
-- Configuration events are not broadcastable to other relays
-- Future: Auth system to restrict admin access to configuration events
-

-## Complete Current Configuration Structure
-
-Based on analysis of [`src/config.c`](src/config.c:753-795), here is the complete current configuration structure that will be converted to event tags:

+# Static Build Improvements
+
+## Overview
+
+The `build_static.sh` script has been updated to properly support MUSL static compilation and includes several optimizations.
+
+## Changes Made
+
+### 1. True MUSL Static Binary Support
+
+The script now attempts to build with `musl-gcc` for truly portable static binaries:
+
+- **MUSL binaries** have zero runtime dependencies and work across all Linux distributions
+- **Automatic fallback** to glibc static linking if MUSL compilation fails (e.g., missing MUSL-compiled libraries)
+- Clear messaging about which type of binary was created
+
+### 2. SQLite Build Caching
+
+SQLite is now built once and cached for future builds:
+
+- **Cache location**: `~/.cache/c-relay-sqlite/`
+- **Version-specific**: Each SQLite version gets its own cache directory
+- **Significant speedup**: Subsequent builds skip the SQLite compilation step
+- **Manual cleanup**: `rm -rf ~/.cache/c-relay-sqlite` to clear cache
+
+### 3. Smart Package Installation
+
+The script now checks for required packages before installing:
+
+- Only installs missing packages
+- Reduces unnecessary `apt` operations
+- Faster builds when dependencies are already present
+
+### 4. Bug Fixes
+
+- Fixed format warning in `src/subscriptions.c` line 1067 (changed `%zu` to `%d` with cast for `MAX_SEARCH_TERM_LENGTH`)
+
+## Usage
+
+```bash
+./build_static.sh
+```
+
+The script will:
+1. Check for and install `musl-gcc` if needed
+2. Build or use cached SQLite with JSON1 support
+3. Attempt MUSL static compilation
+4. Fall back to glibc static compilation if MUSL fails
+5. Verify the resulting binary
+
+## Binary Types
+
+### MUSL Static Binary (Ideal - Currently Not Achievable)
+- **Filename**: `build/c_relay_static_musl_x86_64`
+- **Dependencies**: None (truly static)
+- **Portability**: Works on any Linux distribution
+- **Status**: Requires MUSL-compiled libwebsockets and other dependencies (not available by default)
+
+### Glibc Static Binary (Current Output)
+- **Filename**: `build/c_relay_static_x86_64` or `build/c_relay_static_glibc_x86_64`
+- **Dependencies**: None - fully statically linked with glibc
+- **Portability**: Works on most Linux distributions (glibc is statically included)
+- **Note**: Despite using glibc, this is a **fully static binary** with no runtime dependencies
+
+## Verification
+
+The script automatically verifies binaries using `ldd` and `file`:
+
+```bash
+# For MUSL binary
+ldd build/c_relay_static_musl_x86_64
+# Output: "not a dynamic executable" (good!)
+
+# For glibc binary
+ldd build/c_relay_static_glibc_x86_64
+# Output: Shows glibc dependencies
+```
+
+## Known Limitations
+
+### MUSL Compilation Currently Fails Because:
+
+1. **libwebsockets not available as MUSL static library**
+   - System libwebsockets is compiled with glibc, not MUSL
+   - MUSL cannot link against glibc-compiled libraries
+   - Solution: Build libwebsockets from source with musl-gcc (future enhancement)
+
+2. **Other dependencies not MUSL-compatible**
+   - libssl, libcrypto, libsecp256k1, libcurl must be available as MUSL static libraries
+   - Most systems only provide glibc versions
+   - Solution: Build entire dependency chain with musl-gcc (complex, future enhancement)
+
+### Current Behavior
+
+The script attempts MUSL compilation but falls back to glibc:
+1. Tries to compile with `musl-gcc -static` (fails due to missing MUSL libraries)
+2. Logs the error to `/tmp/musl_build.log`
+3. Displays a clear warning message
+4. Automatically falls back to `gcc -static` with glibc
+5. Produces a **fully static binary** with glibc statically linked (no runtime dependencies)
+
+**Important**: The glibc static binary is still fully portable across most Linux distributions because glibc is statically included in the binary. It's not as universally portable as MUSL would be, but it works on virtually all modern Linux systems.
+
+## Future Enhancements
+
+1. **Full MUSL dependency chain**: Build all dependencies (libwebsockets, OpenSSL, etc.) with musl-gcc
+2. **Multi-architecture support**: Add ARM64 MUSL builds
+3. **Docker-based builds**: Use Alpine Linux containers for guaranteed MUSL environment
+4. **Dependency vendoring**: Include pre-built MUSL libraries in the repository
+
+## Troubleshooting
+
+### Clear SQLite Cache
+```bash
+rm -rf ~/.cache/c-relay-sqlite
+```
+
+### Force Package Reinstall
+```bash
+sudo apt install --reinstall musl-dev musl-tools libssl-dev libcurl4-openssl-dev libsecp256k1-dev
+```
+
+### Check Build Logs
+```bash
+cat /tmp/musl_build.log
+```
+
+### Verify Binary Type
+```bash
+file build/c_relay_static_*
+ldd build/c_relay_static_* 2>&1
+```
+
+## Performance Impact
+
+- **First build**: ~2-3 minutes (includes SQLite compilation)
+- **Subsequent builds**: ~30-60 seconds (uses cached SQLite)
+- **Cache size**: ~10-15 MB per SQLite version
+
+## Compatibility
+
+The updated script is compatible with:
+- Ubuntu 20.04+
+- Debian 10+
+- Other Debian-based distributions with `apt` package manager
+
+For other distributions, adjust package installation commands accordingly.

+# Unified Startup Sequence Design
+
+## Overview
+
+This document describes the new unified startup sequence where all config values are created first, then CLI overrides are applied as a separate atomic operation. This eliminates the current 3-step incremental building process.
+
+## Current Problems
+
+1. **Incremental Config Building**: Config is built in 3 steps:
+   - Step 1: `populate_default_config_values()` - adds defaults
+   - Step 2: CLI overrides applied via `update_config_in_table()`
+   - Step 3: `add_pubkeys_to_config_table()` - adds generated keys
+
+2. **Race Conditions**: Cache can be refreshed between steps, causing incomplete config reads
+
+3. **Complexity**: Multiple code paths for first-time vs restart scenarios
+
+## New Design Principles
+
+1. **Atomic Config Creation**: All config values created in single transaction
+2. **Separate Override Phase**: CLI overrides applied after complete config exists
+3. **Unified Code Path**: Same logic for first-time and restart scenarios
+4. **Cache Safety**: Cache only loaded after config is complete
+
+---
+
+## Scenario 1: First-Time Startup (No Database)
+
+### Sequence
+
+```
+1. Key Generation Phase
+   ├─ generate_random_private_key_bytes() → admin_privkey_bytes
+   ├─ nostr_bytes_to_hex() → admin_privkey (hex)
+   ├─ nostr_ec_public_key_from_private_key() → admin_pubkey_bytes
+   ├─ nostr_bytes_to_hex() → admin_pubkey (hex)
+   ├─ generate_random_private_key_bytes() → relay_privkey_bytes
+   ├─ nostr_bytes_to_hex() → relay_privkey (hex)
+   ├─ nostr_ec_public_key_from_private_key() → relay_pubkey_bytes
+   └─ nostr_bytes_to_hex() → relay_pubkey (hex)
+
+2. Database Creation Phase
+   ├─ create_database_with_relay_pubkey(relay_pubkey)
+   │  └─ Sets g_database_path = "<relay_pubkey>.db"
+   └─ init_database(g_database_path)
+      └─ Creates database with embedded schema (includes config table)
+
+3. Complete Config Population Phase (ATOMIC)
+   ├─ BEGIN TRANSACTION
+   ├─ populate_all_config_values_atomic()
+   │  ├─ Insert ALL default config values from DEFAULT_CONFIG_VALUES[]
+   │  ├─ Insert admin_pubkey
+   │  └─ Insert relay_pubkey
+   └─ COMMIT TRANSACTION
+
+4. CLI Override Phase (ATOMIC)
+   ├─ BEGIN TRANSACTION
+   ├─ apply_cli_overrides()
+   │  ├─ IF cli_options.port_override > 0:
+   │  │  └─ UPDATE config SET value = ? WHERE key = 'relay_port'
+   │  ├─ IF cli_options.admin_pubkey_override[0]:
+   │  │  └─ UPDATE config SET value = ? WHERE key = 'admin_pubkey'
+   │  └─ IF cli_options.relay_privkey_override[0]:
+   │     └─ UPDATE config SET value = ? WHERE key = 'relay_privkey'
+   └─ COMMIT TRANSACTION
+
+5. Secure Key Storage Phase
+   └─ store_relay_private_key(relay_privkey)
+      └─ INSERT INTO relay_seckey (private_key_hex) VALUES (?)
+
+6. Cache Initialization Phase
+   └─ refresh_unified_cache_from_table()
+      └─ Loads complete config into g_unified_cache
+```
+
+### Function Call Sequence
+
+```c
+// In main.c - first_time_startup branch
+if (is_first_time_startup()) {
+    // 1. Key Generation
+    first_time_startup_sequence(&cli_options);

+    store_relay_private_key(relay_privkey);
+    
+    // 6. Cache Initialization

+    refresh_unified_cache_from_table();
+}
+```
+
+---
+
+## Key Improvements
+
+### 1. Atomic Config Creation
+
+**Before:**
+```c
+populate_default_config_values();  // Step 1
+update_config_in_table("relay_port", port_str);  // Step 2
+add_pubkeys_to_config_table();  // Step 3
+```
+
+**After:**
+```c
+populate_all_config_values_atomic(&cli_options);  // Single transaction
+apply_cli_overrides_atomic(&cli_options);  // Separate transaction
+```
+
+### 2. Elimination of Race Conditions
+
+**Before:**
+- Cache could refresh between steps 1-3
+- Incomplete config could be read
+
+**After:**
+- Config created atomically
+- Cache only refreshed after complete config exists
+
+### 3. Unified Code Path
+
+**Before:**
+- Different logic for first-time vs restart
+- `populate_default_config_values()` vs `add_pubkeys_to_config_table()`
+
+**After:**
+- Same validation logic for both scenarios
+- `validate_config_table_completeness()` handles both cases
+
+### 4. Clear Separation of Concerns
+
+**Before:**
+- CLI overrides mixed with default population
+- Unclear when overrides are applied
+
+**After:**
+- Phase 1: Complete config creation
+- Phase 2: CLI overrides (if any)
+- Phase 3: Cache initialization
+
+---
+
+## Implementation Changes Required
+
+### 1. New Functions in config.c
+
+```c
+// Atomic config population for first-time startup
+int populate_all_config_values_atomic(const cli_options_t* cli_options);
+
+// Atomic CLI override application
+int apply_cli_overrides_atomic(const cli_options_t* cli_options);
+
+// Config validation for existing databases
+int validate_config_table_completeness(void);
+int populate_missing_config_values(void);
+
+// Helper function
+int has_cli_overrides(const cli_options_t* cli_options);
+```
+
+### 2. Modified Functions in config.c
+
+```c
+// Simplify to only generate keys and set database path
+int first_time_startup_sequence(const cli_options_t* cli_options);
+
+// Remove config population logic
+int add_pubkeys_to_config_table(void);  // DEPRECATED - logic moved to populate_all_config_values_atomic()
+```
+
+### 3. Modified Startup Flow in main.c
+
+```c
+// First-time startup
+if (is_first_time_startup()) {
+    first_time_startup_sequence(&cli_options);
+    init_database(g_database_path);
+    populate_all_config_values_atomic(&cli_options);  // NEW
+    apply_cli_overrides_atomic(&cli_options);  // NEW
+    store_relay_private_key(relay_privkey);
+    refresh_unified_cache_from_table();
+}
+
+// Existing relay
+else {
+    startup_existing_relay(relay_pubkey);
+    init_database(g_database_path);
+    validate_config_table_completeness();  // NEW
+    if (has_cli_overrides(&cli_options)) {
+        apply_cli_overrides_atomic(&cli_options);  // NEW
+    }
+    refresh_unified_cache_from_table();
+}
+```
+
+---
+
+## Benefits
+
+1. **Atomicity**: Config creation is atomic - no partial states
+2. **Simplicity**: Clear phases with single responsibility
+3. **Safety**: Cache only loaded after complete config exists
+4. **Consistency**: Same validation logic for all scenarios
+5. **Maintainability**: Easier to understand and modify
+6. **Testability**: Each phase can be tested independently
+
+---
+
+## Migration Path
+
+1. Implement new functions in config.c
+2. Update main.c startup flow
+3. Test first-time startup scenario
+4. Test restart with CLI overrides
+5. Test restart without CLI overrides
+6. Remove deprecated functions
+7. Update documentation
+
+---
+
+## Testing Strategy
+
+### Test Cases
+
+1. **First-time startup with defaults**
+   - Verify all config values created atomically
+   - Verify cache loads complete config
+
+2. **First-time startup with port override**
+   - Verify defaults created first
+   - Verify port override applied second
+   - Verify cache reflects override
+
+3. **Restart with complete config**
+   - Verify no config changes
+   - Verify cache loads immediately
+
+4. **Restart with missing config keys**
+   - Verify missing keys populated
+   - Verify existing keys unchanged
+
+5. **Restart with CLI overrides**
+   - Verify overrides applied atomically
+   - Verify cache invalidated and refreshed
+
+### Validation Points
+
+- Config table row count after each phase
+- Cache validity state after each phase
+- Transaction boundaries (BEGIN/COMMIT)
+- Error handling for failed transactions

+- Verify all DEFAULT_CONFIG_VALUES inserted
+- Verify admin_pubkey and relay_pubkey inserted
+- Verify error handling on failure

+### Step 1.3: Implement `validate_config_table_completeness()`
+
+**Location**: `src/config.c`
+
+**Purpose**: Validate config table has all required keys, populate missing ones

+
+**Testing**:

+
+## Phase 2: Update Function Declarations in config.h
+
+### Step 2.1: Add New Function Declarations
+
+**Location**: `src/config.h`
+
+**Changes**:
+```c
+// Add after existing function declarations
+
+// Atomic config population for first-time startup
+int populate_all_config_values_atomic(const cli_options_t* cli_options);

+
+## Phase 3: Refactor Startup Flow in main.c
+
+### Step 3.1: Update First-Time Startup Branch
+
+**Location**: `src/main.c` (around lines 1624-1740)
+
+**Current Code**:
+```c
+if (is_first_time_startup()) {

+}
+```
+
+**Testing**:
+- Verify first-time startup creates complete config
+- Verify CLI overrides applied correctly
+- Verify cache loads complete config
+- Verify error handling at each step
+
+---
+
+### Step 3.2: Update Existing Relay Startup Branch
+
+**Location**: `src/main.c` (around lines 1741-1928)
+
+**Current Code**:
+```c
+else {

+        }
+    }
+    
+    // 5. Load complete config into cache
+    refresh_unified_cache_from_table();

+```
+
+**Testing**:
+- Verify existing relay startup with complete config
+- Verify missing keys populated
+- Verify CLI overrides applied when present
+- Verify no changes when no overrides
+- Verify cache loads correctly
+

+
+## Phase 4: Deprecate Old Functions
+
+### Step 4.1: Mark Functions as Deprecated
+
+**Location**: `src/config.c`
+
+**Functions to Deprecate**:
+1. `populate_default_config_values()` - replaced by `populate_all_config_values_atomic()`
+2. `add_pubkeys_to_config_table()` - logic moved to `populate_all_config_values_atomic()`
+
+**Changes**:
+```c
+// Mark as deprecated in comments
+// DEPRECATED: Use populate_all_config_values_atomic() instead
+// This function will be removed in a future version
+int populate_default_config_values(void) {
+    // ... existing implementation ...
+}
+
+// DEPRECATED: Use populate_all_config_values_atomic() instead
+// This function will be removed in a future version
+int add_pubkeys_to_config_table(void) {
+    // ... existing implementation ...
+}
+```
+
+---
+
+## Phase 5: Testing Strategy
+
+### Unit Tests
+
+1. **Test `populate_all_config_values_atomic()`**
+   - Test with valid cli_options
+   - Test transaction rollback on error
+   - Test all config keys inserted
+   - Test pubkeys inserted correctly
+
+2. **Test `apply_cli_overrides_atomic()`**
+   - Test port override
+   - Test admin_pubkey override
+   - Test relay_privkey override
+   - Test multiple overrides
+   - Test no overrides
+   - Test transaction rollback on error
+
+3. **Test `validate_config_table_completeness()`**
+   - Test with complete config
+   - Test with missing keys
+   - Test population of missing keys
+
+4. **Test `has_cli_overrides()`**
+   - Test with each override type
+   - Test with no overrides
+   - Test with NULL cli_options
+
+### Integration Tests
+
+1. **First-Time Startup**
+   ```bash
+   # Clean environment
+   rm -f *.db
+   
+   # Start relay with defaults
+   ./build/c_relay_x86
+   
+   # Verify config table complete
+   sqlite3 <relay_pubkey>.db "SELECT COUNT(*) FROM config;"
+   # Expected: 20+ rows (all defaults + pubkeys)
+   
+   # Verify cache loaded
+   # Check relay.log for cache refresh message
+   ```
+
+2. **First-Time Startup with CLI Overrides**
+   ```bash
+   # Clean environment
+   rm -f *.db
+   
+   # Start relay with port override
+   ./build/c_relay_x86 --port 9999
+   
+   # Verify port override applied
+   sqlite3 <relay_pubkey>.db "SELECT value FROM config WHERE key='relay_port';"
+   # Expected: 9999
+   ```
+
+3. **Restart with Existing Database**
+   ```bash
+   # Start relay (creates database)
+   ./build/c_relay_x86
+   
+   # Stop relay
+   pkill -f c_relay_
+   
+   # Restart relay
+   ./build/c_relay_x86
+   
+   # Verify config unchanged
+   # Check relay.log for validation message
+   ```
+
+4. **Restart with CLI Overrides**
+   ```bash
+   # Start relay (creates database)
+   ./build/c_relay_x86
+   
+   # Stop relay
+   pkill -f c_relay_
+   
+   # Restart with port override
+   ./build/c_relay_x86 --port 9999
+   
+   # Verify port override applied
+   sqlite3 <relay_pubkey>.db "SELECT value FROM config WHERE key='relay_port';"
+   # Expected: 9999
+   ```
+
+### Regression Tests
+
+Run existing test suite to ensure no breakage:
+```bash
+./tests/run_all_tests.sh
+```
+
+---
+
+## Phase 6: Documentation Updates
+
+### Files to Update
+
+1. **docs/configuration_guide.md**
+   - Update startup sequence description
+   - Document new atomic config creation
+   - Document CLI override behavior
+
+2. **docs/startup_flows_complete.md**
+   - Update with new flow diagrams
+   - Document new function calls
+
+3. **README.md**
+   - Update CLI options documentation
+   - Document override behavior
+
+---
+
+## Implementation Timeline

+
+### Week 2: Integration

+- Day 3-4: Testing and bug fixes
+- Day 5: Documentation updates
+
+### Week 3: Cleanup
+- Day 1-2: Deprecate old functions
+- Day 3-4: Final testing and validation
+- Day 5: Code review and merge
+
+---
+
+## Risk Mitigation
+
+### Potential Issues
+
+1. **Database Lock Contention**
+   - Risk: Multiple transactions could cause locks
+   - Mitigation: Use BEGIN IMMEDIATE for write transactions
+
+2. **Cache Invalidation Timing**
+   - Risk: Cache could be read before overrides applied
+   - Mitigation: Invalidate cache immediately after overrides
+
+3. **Backward Compatibility**
+   - Risk: Existing databases might have incomplete config
+   - Mitigation: `validate_config_table_completeness()` handles this
+
+4. **Transaction Rollback**
+   - Risk: Partial config on error
+   - Mitigation: All operations in transactions with proper rollback
+
+---
+
+## Success Criteria
+
+1. ✅ All config values created atomically in first-time startup
+2. ✅ CLI overrides applied in separate atomic transaction
+3. ✅ Existing databases validated and missing keys populated
+4. ✅ Cache only loaded after complete config exists
+5. ✅ All existing tests pass
+6. ✅ No race conditions in config creation
+7. ✅ Clear separation between config creation and override phases
+
+---
+
+## Rollback Plan
+
+If issues arise during implementation:
+
+1. **Revert main.c changes** - restore original startup flow
+2. **Keep new functions** - they can coexist with old code
+3. **Add feature flag** - allow toggling between old and new behavior
+4. **Gradual migration** - enable new behavior per scenario
+
+```c
+// Feature flag approach
+#define USE_ATOMIC_CONFIG_CREATION 1
+
+#if USE_ATOMIC_CONFIG_CREATION
+    // New atomic approach
+    populate_all_config_values_atomic(&cli_options);
+    apply_cli_overrides_atomic(&cli_options);
+#else
+    // Old incremental approach
+    populate_default_config_values();
+    // ... existing code ...
+#endif
+```

+## Web Admin Interface
+
+The relay includes a built-in web-based administration interface that provides a user-friendly way to manage your relay without command-line tools.
+
+### Accessing the Interface
+
+1. **Open your browser** and navigate to: `http://localhost:8888/api/`
+2. **Authenticate** using your Nostr identity (the admin interface uses NIP-42 authentication)
+3. **Manage configuration** through the web interface
+
+### Features
+
+- **Real-time Configuration**: View and edit all relay settings
+- **Database Statistics**: Monitor event counts, storage usage, and performance metrics
+- **Auth Rules Management**: Configure whitelist/blacklist rules for pubkeys
+- **Relay Connection Testing**: Verify WebSocket connectivity and NIP-11 information
+- **Event-Based Updates**: All changes are applied as signed Nostr events
+
+### Security Notes
+
+- The web interface requires NIP-42 authentication with your admin pubkey
+- All configuration changes are cryptographically signed
+- The interface serves embedded static files (no external dependencies)
+- CORS headers are included for proper browser operation
+
+### Browser Compatibility
+
+The admin interface works with modern browsers that support:
+- WebSocket connections
+- ES6 JavaScript features
+- Modern CSS Grid and Flexbox layouts
+

+#### Encrypt with XChaCha20-Poly1305
+
+```js
+import { xchacha20poly1305 } from '@noble/ciphers/chacha';
+import { utf8ToBytes } from '@noble/ciphers/utils';
+import { randomBytes } from '@noble/ciphers/webcrypto';
+const key = randomBytes(32);
+const nonce = randomBytes(24);
+const chacha = xchacha20poly1305(key, nonce);
+const data = utf8ToBytes('hello, noble');
+const ciphertext = chacha.encrypt(data);
+const data_ = chacha.decrypt(ciphertext); // utils.bytesToUtf8(data_) === data
+```
+
+#### Encrypt with AES-256-GCM
+
+```js
+import { gcm } from '@noble/ciphers/aes';
+import { utf8ToBytes } from '@noble/ciphers/utils';
+import { randomBytes } from '@noble/ciphers/webcrypto';
+const key = randomBytes(32);
+const nonce = randomBytes(24);
+const aes = gcm(key, nonce);
+const data = utf8ToBytes('hello, noble');
+const ciphertext = aes.encrypt(data);
+const data_ = aes.decrypt(ciphertext); // utils.bytesToUtf8(data_) === data
+```
+
+#### Use existing key instead of a new one
+
+```js
+const key = new Uint8Array([
+  169, 88, 160, 139, 168, 29, 147, 196, 14, 88, 237, 76, 243, 177, 109, 140, 195, 140, 80, 10, 216,
+  134, 215, 71, 191, 48, 20, 104, 189, 37, 38, 55,
+]);
+const nonce = new Uint8Array([
+  180, 90, 27, 63, 160, 191, 150, 33, 67, 212, 86, 71, 144, 6, 200, 102, 218, 32, 23, 147, 8, 41,
+  147, 11,
+]);
+// or, hex:
+import { hexToBytes } from '@noble/ciphers/utils';
+const key2 = hexToBytes('4b7f89bac90a1086fef73f5da2cbe93b2fae9dfbf7678ae1f3e75fd118ddf999');
+const nonce2 = hexToBytes('9610467513de0bbd7c4cc2c3c64069f1802086fbd3232b13');
+```
+
+#### Encrypt without nonce
+
+```js
+import { xchacha20poly1305 } from '@noble/ciphers/chacha';
+import { managedNonce } from '@noble/ciphers/webcrypto';
+import { hexToBytes, utf8ToBytes } from '@noble/ciphers/utils';
+const key = hexToBytes('fa686bfdffd3758f6377abbc23bf3d9bdc1a0dda4a6e7f8dbdd579fa1ff6d7e1');
+const chacha = managedNonce(xchacha20poly1305)(key); // manages nonces for you
+const data = utf8ToBytes('hello, noble');
+const ciphertext = chacha.encrypt(data);
+const data_ = chacha.decrypt(ciphertext);
+```
+
+#### Use same array for input and output
+
+```js
+import { chacha20poly1305 } from '@noble/ciphers/chacha';
+import { utf8ToBytes } from '@noble/ciphers/utils';
+import { randomBytes } from '@noble/ciphers/webcrypto';
+
+const key = randomBytes(32);
+const nonce = randomBytes(12);
+const buf = new Uint8Array(12 + 16);
+const _data = utf8ToBytes('hello, noble');
+buf.set(_data, 0); // first 12 bytes
+const _12b = buf.subarray(0, 12);
+
+const chacha = chacha20poly1305(key, nonce);
+chacha.encrypt(_12b, buf);
+chacha.decrypt(buf, _12b); // _12b now same as _data
+```
+
+#### All imports
+
+```js
+import { gcm, siv } from '@noble/ciphers/aes';
+import { xsalsa20poly1305 } from '@noble/ciphers/salsa';
+import { chacha20poly1305, xchacha20poly1305 } from '@noble/ciphers/chacha';
+
+// Unauthenticated encryption: make sure to use HMAC or similar
+import { ctr, cfb, cbc, ecb } from '@noble/ciphers/aes';
+import { salsa20, xsalsa20 } from '@noble/ciphers/salsa';
+import { chacha20, xchacha20, chacha8, chacha12 } from '@noble/ciphers/chacha';
+
+// Utilities
+import { bytesToHex, hexToBytes, bytesToUtf8, utf8ToBytes } from '@noble/ciphers/utils';
+import { managedNonce, randomBytes } from '@noble/ciphers/webcrypto';
+```
+
+## Implementations
+
+### Salsa
+
+```js
+import { xsalsa20poly1305 } from '@noble/ciphers/salsa';
+import { secretbox } from '@noble/ciphers/salsa'; // == xsalsa20poly1305
+import { salsa20, xsalsa20 } from '@noble/ciphers/salsa';
+```
+
+[Salsa20](https://cr.yp.to/snuffle.html) stream cipher was released in 2005.
+Salsa's goal was to implement AES replacement that does not rely on S-Boxes,
+which are hard to implement in a constant-time manner.
+Salsa20 is usually faster than AES, a big deal on slow, budget mobile phones.
+
+[XSalsa20](https://cr.yp.to/snuffle/xsalsa-20110204.pdf), extended-nonce
+variant was released in 2008. It switched nonces from 96-bit to 192-bit,
+and became safe to be picked at random.
+
+Nacl / Libsodium popularized term "secretbox", a simple black-box
+authenticated encryption. Secretbox is just xsalsa20-poly1305. We provide the
+alias and corresponding seal / open methods. We don't provide "box" or "sealedbox".
+
+Check out [PDF](https://cr.yp.to/snuffle/salsafamily-20071225.pdf) and
+[wiki](https://en.wikipedia.org/wiki/Salsa20).
+
+### ChaCha
+
+```js
+import { chacha20poly1305, xchacha20poly1305 } from '@noble/ciphers/chacha';
+import { chacha20, xchacha20, chacha8, chacha12 } from '@noble/ciphers/chacha';
+```
+
+[ChaCha20](https://cr.yp.to/chacha.html) stream cipher was released
+in 2008. ChaCha aims to increase the diffusion per round, but had slightly less
+cryptanalysis. It was standardized in
+[RFC 8439](https://datatracker.ietf.org/doc/html/rfc8439) and is now used in TLS 1.3.
+
+[XChaCha20](https://datatracker.ietf.org/doc/html/draft-irtf-cfrg-xchacha)
+extended-nonce variant is also provided. Similar to XSalsa, it's safe to use with
+randomly-generated nonces.
+
+Check out [PDF](http://cr.yp.to/chacha/chacha-20080128.pdf) and [wiki](https://en.wikipedia.org/wiki/Salsa20).
+
+### AES
+
+```js
+import { gcm, siv, ctr, cfb, cbc, ecb } from '@noble/ciphers/aes';
+import { randomBytes } from '@noble/ciphers/webcrypto';
+const plaintext = new Uint8Array(32).fill(16);
+const key = randomBytes(32); // 24 for AES-192, 16 for AES-128
+for (let cipher of [gcm, siv]) {
+  const stream = cipher(key, randomBytes(12));
+  const ciphertext_ = stream.encrypt(plaintext);
+  const plaintext_ = stream.decrypt(ciphertext_);
+}
+for (const cipher of [ctr, cbc, cbc]) {
+  const stream = cipher(key, randomBytes(16));
+  const ciphertext_ = stream.encrypt(plaintext);
+  const plaintext_ = stream.decrypt(ciphertext_);
+}
+for (const cipher of [ecb]) {
+  const stream = cipher(key);
+  const ciphertext_ = stream.encrypt(plaintext);
+  const plaintext_ = stream.decrypt(ciphertext_);
+}
+```
+
+[AES](https://en.wikipedia.org/wiki/Advanced_Encryption_Standard)
+is a variant of Rijndael block cipher, standardized by NIST in 2001.
+We provide the fastest available pure JS implementation.
+
+We support AES-128, AES-192 and AES-256: the mode is selected dynamically,
+based on key length (16, 24, 32).
+
+[AES-GCM-SIV](https://en.wikipedia.org/wiki/AES-GCM-SIV)
+nonce-misuse-resistant mode is also provided. It's recommended to use it,
+to prevent catastrophic consequences of nonce reuse. Our implementation of SIV
+has the same speed as GCM: there is no performance hit.
+
+Check out [AES internals and block modes](#aes-internals-and-block-modes).
+
+### Webcrypto AES
+
+```js
+import { gcm, ctr, cbc, randomBytes } from '@noble/ciphers/webcrypto';
+const plaintext = new Uint8Array(32).fill(16);
+const key = randomBytes(32);
+for (const cipher of [gcm]) {
+  const stream = cipher(key, randomBytes(12));
+  const ciphertext_ = await stream.encrypt(plaintext);
+  const plaintext_ = await stream.decrypt(ciphertext_);
+}
+for (const cipher of [ctr, cbc]) {
+  const stream = cipher(key, randomBytes(16));
+  const ciphertext_ = await stream.encrypt(plaintext);
+  const plaintext_ = await stream.decrypt(ciphertext_);
+}
+```
+
+We also have a separate wrapper over WebCrypto built-in.
+
+It's the same as using `crypto.subtle`, but with massively simplified API.
+
+Unlike pure js version, it's asynchronous.
+
+### Poly1305, GHash, Polyval
+
+```js
+import { poly1305 } from '@noble/ciphers/_poly1305';
+import { ghash, polyval } from '@noble/ciphers/_polyval';
+```
+
+We expose polynomial-evaluation MACs: [Poly1305](https://cr.yp.to/mac.html),
+AES-GCM's [GHash](https://en.wikipedia.org/wiki/Galois/Counter_Mode) and
+AES-SIV's [Polyval](https://en.wikipedia.org/wiki/AES-GCM-SIV).
+
+Poly1305 ([PDF](https://cr.yp.to/mac/poly1305-20050329.pdf),
+[wiki](https://en.wikipedia.org/wiki/Poly1305))
+is a fast and parallel secret-key message-authentication code suitable for
+a wide variety of applications. It was standardized in
+[RFC 8439](https://datatracker.ietf.org/doc/html/rfc8439) and is now used in TLS 1.3.
+
+Polynomial MACs are not perfect for every situation:
+they lack Random Key Robustness: the MAC can be forged, and can't
+be used in PAKE schemes. See
+[invisible salamanders attack](https://keymaterial.net/2020/09/07/invisible-salamanders-in-aes-gcm-siv/).
+To combat invisible salamanders, `hash(key)` can be included in ciphertext,
+however, this would violate ciphertext indistinguishability:
+an attacker would know which key was used - so `HKDF(key, i)`
+could be used instead.
+
+### FF1
+
+Format-preserving encryption algorithm (FPE-FF1) specified in NIST Special Publication 800-38G.
+[See more info](https://nvlpubs.nist.gov/nistpubs/SpecialPublications/NIST.SP.800-38G.pdf).
+
+### Managed nonces
+
+```js
+import { managedNonce } from '@noble/ciphers/webcrypto';
+import { gcm, siv, ctr, cbc, cbc, ecb } from '@noble/ciphers/aes';
+import { xsalsa20poly1305 } from '@noble/ciphers/salsa';
+import { chacha20poly1305, xchacha20poly1305 } from '@noble/ciphers/chacha';
+
+const wgcm = managedNonce(gcm);
+const wsiv = managedNonce(siv);
+const wcbc = managedNonce(cbc);
+const wctr = managedNonce(ctr);
+const wsalsapoly = managedNonce(xsalsa20poly1305);
+const wchacha = managedNonce(chacha20poly1305);
+const wxchacha = managedNonce(xchacha20poly1305);
+
+// Now:
+const encrypted = wgcm(key).encrypt(data); // no nonces
+```
+
+We provide API that manages nonce internally instead of exposing them to library's user.
+
+For `encrypt`, a `nonceBytes`-length buffer is fetched from CSPRNG and prenended to encrypted ciphertext.
+
+For `decrypt`, first `nonceBytes` of ciphertext are treated as nonce.
+
+## Guidance
+
+### Which cipher should I pick?
+
+XChaCha20-Poly1305 is the safest bet these days.
+AES-GCM-SIV is the second safest.
+AES-GCM is the third.
+
+### How to encrypt properly
+
+- Use unpredictable key with enough entropy
+  - Random key must be using cryptographically secure random number generator (CSPRNG), not `Math.random` etc.
+  - Non-random key generated from KDF is fine
+  - Re-using key is fine, but be aware of rules for cryptographic key wear-out and [encryption limits](#encryption-limits)
+- Use new nonce every time and [don't repeat it](#nonces)
+  - chacha and salsa20 are fine for sequential counters that _never_ repeat: `01, 02...`
+  - xchacha and xsalsa20 should be used for random nonces instead
+- Prefer authenticated encryption (AEAD)
+  - HMAC+ChaCha / HMAC+AES / chacha20poly1305 / aes-gcm is good
+  - chacha20 without poly1305 or hmac / aes-ctr / aes-cbc is bad
+  - Flipping bits or ciphertext substitution won't be detected in unauthenticated ciphers
+- Don't re-use keys between different protocols
+  - For example, using secp256k1 key in AES is bad
+  - Use hkdf or, at least, a hash function to create sub-key instead
+
+### Nonces
+
+Most ciphers need a key and a nonce (aka initialization vector / IV) to encrypt a data:
+
+    ciphertext = encrypt(plaintext, key, nonce)
+
+Repeating (key, nonce) pair with different plaintexts would allow an attacker to decrypt it:
+
+    ciphertext_a = encrypt(plaintext_a, key, nonce)
+    ciphertext_b = encrypt(plaintext_b, key, nonce)
+    stream_diff = xor(ciphertext_a, ciphertext_b)   # Break encryption
+
+So, you can't repeat nonces. One way of doing so is using counters:
+
+    for i in 0..:
+        ciphertext[i] = encrypt(plaintexts[i], key, i)
+
+Another is generating random nonce every time:
+
+    for i in 0..:
+        rand_nonces[i] = random()
+        ciphertext[i] = encrypt(plaintexts[i], key, rand_nonces[i])
+
+Counters are OK, but it's not always possible to store current counter value:
+e.g. in decentralized, unsyncable systems.
+
+Randomness is OK, but there's a catch:
+ChaCha20 and AES-GCM use 96-bit / 12-byte nonces, which implies
+higher chance of collision. In the example above,
+`random()` can collide and produce repeating nonce.
+
+To safely use random nonces, utilize XSalsa20 or XChaCha:
+they increased nonce length to 192-bit, minimizing a chance of collision.
+AES-SIV is also fine. In situations where you can't use eXtended-nonce
+algorithms, key rotation is advised. hkdf would work great for this case.
+
+### Encryption limits
+
+A "protected message" would mean a probability of `2**-50` that a passive attacker
+successfully distinguishes the ciphertext outputs of the AEAD scheme from the outputs
+of a random function. See [draft-irtf-cfrg-aead-limits](https://datatracker.ietf.org/doc/draft-irtf-cfrg-aead-limits/) for details.
+
+- Max message size:
+  - AES-GCM: ~68GB, `2**36-256`
+  - Salsa, ChaCha, XSalsa, XChaCha: ~256GB, `2**38-64`
+- Max amount of protected messages, under same key:
+  - AES-GCM: `2**32.5`
+  - Salsa, ChaCha: `2**46`, but only integrity is affected, not confidentiality
+  - XSalsa, XChaCha: `2**72`
+- Max amount of protected messages, across all keys:
+  - AES-GCM: `2**69/B` where B is max blocks encrypted by a key. Meaning
+    `2**59` for 1KB, `2**49` for 1MB, `2**39` for 1GB
+  - Salsa, ChaCha, XSalsa, XChaCha: `2**100`
+
+##### AES internals and block modes
+
+`cipher = encrypt(block, key)`. Data is split into 128-bit blocks. Encrypted in 10/12/14 rounds (128/192/256bit). Every round does:
+
+1. **S-box**, table substitution
+2. **Shift rows**, cyclic shift left of all rows of data array
+3. **Mix columns**, multiplying every column by fixed polynomial
+4. **Add round key**, round_key xor i-th column of array
+
+For non-deterministic (not ECB) schemes, initialization vector (IV) is mixed to block/key;
+and each new round either depends on previous block's key, or on some counter.
+
+- ECB — simple deterministic replacement. Dangerous: always map x to y. See [AES Penguin](https://words.filippo.io/the-ecb-penguin/)
+- CBC — key is previous round’s block. Hard to use: need proper padding, also needs MAC
+- CTR — counter, allows to create streaming cipher. Requires good IV. Parallelizable. OK, but no MAC
+- GCM — modern CTR, parallel, with MAC
+- SIV — synthetic initialization vector, nonce-misuse-resistant. Guarantees that, when a nonce is repeated,
+  the only security loss is that identical plaintexts will produce identical ciphertexts.
+- XTS — used in hard drives. Similar to ECB (deterministic), but has `[i][j]`
+  tweak arguments corresponding to sector i and 16-byte block (part of sector) j. Not authenticated!
+
+GCM / SIV are not ideal:
+
+- Conservative key wear-out is `2**32` (4B) msgs
+- MAC can be forged: see Poly1305 section above. Same for SIV
+
+## Security
+
+The library has not been independently audited yet.
+
+It is tested against property-based, cross-library and Wycheproof vectors,
+and has fuzzing by [Guido Vranken's cryptofuzz](https://github.com/guidovranken/cryptofuzz).
+
+If you see anything unusual: investigate and report.
+
+### Constant-timeness
+
+_JIT-compiler_ and _Garbage Collector_ make "constant time" extremely hard to
+achieve [timing attack](https://en.wikipedia.org/wiki/Timing_attack) resistance
+in a scripting language. Which means _any other JS library can't have
+constant-timeness_. Even statically typed Rust, a language without GC,
+[makes it harder to achieve constant-time](https://www.chosenplaintext.ca/open-source/rust-timing-shield/security)
+for some cases. If your goal is absolute security, don't use any JS lib — including bindings to native ones.
+Use low-level libraries & languages. Nonetheless we're targetting algorithmic constant time.
+
+AES uses T-tables, which means it can't be done in constant-time in JS.
+
+### Supply chain security
+
+- **Commits** are signed with PGP keys, to prevent forgery. Make sure to verify commit signatures.
+- **Releases** are transparent and built on GitHub CI. Make sure to verify [provenance](https://docs.npmjs.com/generating-provenance-statements) logs
+- **Rare releasing** is followed to ensure less re-audit need for end-users
+- **Dependencies** are minimized and locked-down:
+  - If your app has 500 dependencies, any dep could get hacked and you'll be downloading
+    malware with every install. We make sure to use as few dependencies as possible
+  - We prevent automatic dependency updates by locking-down version ranges. Every update is checked with `npm-diff`
+- **Dev Dependencies** are only used if you want to contribute to the repo. They are disabled for end-users:
+  - scure-base, micro-bmark and micro-should are developed by the same author and follow identical security practices
+  - prettier (linter), fast-check (property-based testing) and typescript are used for code quality, vector generation and ts compilation. The packages are big, which makes it hard to audit their source code thoroughly and fully
+
+### Randomness
+
+We're deferring to built-in
+[crypto.getRandomValues](https://developer.mozilla.org/en-US/docs/Web/API/Crypto/getRandomValues)
+which is considered cryptographically secure (CSPRNG).
+
+In the past, browsers had bugs that made it weak: it may happen again.
+Implementing a userspace CSPRNG to get resilient to the weakness
+is even worse: there is no reliable userspace source of quality entropy.
+
+## Speed
+
+To summarize, noble is the fastest JS implementation of Salsa, ChaCha and AES.
+
+You can gain additional speed-up and
+avoid memory allocations by passing `output`
+uint8array into encrypt / decrypt methods.

+- Caveat: Cannot be re-used through all cases:
+- * chacha has (counter | nonce)
+- * xchacha has (nonce16 | counter | nonce16)
+- Idea B: separate nonce / counter and provide separate API for counter re-use
+- Caveat: there are different counter sizes depending on an algorithm.
+- salsa & chacha also differ in structures of key & sigma:

+RFC8439 requires multi-step cipher stream, where
+authKey starts with counter: 0, actual msg with counter: 1.
+
+For this, we need a way to re-use nonce / counter:
+
+    const counter = new Uint8Array(4);
+    chacha(..., counter, ...); // counter is now 1
+    chacha(..., counter, ...); // counter is now 2
+
+This is complicated:
+
+- 32-bit counters are enough, no need for 64-bit: max ArrayBuffer size in JS is 4GB
+- Original papers don't allow mutating counters
+- Counter overflow is undefined [^1]
+- Idea A: allow providing (nonce | counter) instead of just nonce, re-use it
+- Caveat: Cannot be re-used through all cases:
+- * chacha has (counter | nonce)
+- * xchacha has (nonce16 | counter | nonce16)
+- Idea B: separate nonce / counter and provide separate API for counter re-use
+- Caveat: there are different counter sizes depending on an algorithm.
+- salsa & chacha also differ in structures of key & sigma:
+  salsa20:      s[0] | k(4) | s[1] | nonce(2) | ctr(2) | s[2] | k(4) | s[3]
+  chacha:       s(4) | k(8) | ctr(1) | nonce(3)
+  chacha20orig: s(4) | k(8) | ctr(2) | nonce(2)
+- Idea C: helper method such as `setSalsaState(key, nonce, sigma, data)`
+- Caveat: we can't re-use counter array
+
+xchacha [^2] uses the subkey and remaining 8 byte nonce with ChaCha20 as normal
+(prefixed by 4 NUL bytes, since [RFC8439] specifies a 12-byte nonce).

+AES (Advanced Encryption Standard) aka Rijndael block cipher.

+Data is split into 128-bit blocks. Encrypted in 10/12/14 rounds (128/192/256 bits). In every round:
+1. **S-box**, table substitution
+2. **Shift rows**, cyclic shift left of all rows of data array
+3. **Mix columns**, multiplying every column by fixed polynomial
+4. **Add round key**, round_key xor i-th column of array
