+**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 applies during first-time startup and existing relay restarts
+- After database creation, all config comes from events (but CLI overrides can still be applied)
+- 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

+# Relay
+
+I am releasing the code for the nostr relay that I wrote use myself. The code is free for anyone to use in any way that they wish.
+
+Some of the features of this relay are conventional, and some are unconventional.
+
+## The conventional
+
+This relay is written in C99 with a sqlite database.
+
+It implements the following NIPs.
+
+- [x] NIP-01: Basic protocol flow implementation
+- [x] NIP-09: Event deletion
+- [x] NIP-11: Relay information document
+- [x] NIP-13: Proof of Work
+- [x] NIP-15: End of Stored Events Notice
+- [x] NIP-20: Command Results
+- [x] NIP-33: Parameterized Replaceable Events
+- [x] NIP-40: Expiration Timestamp
+- [x] NIP-42: Authentication of clients to relays
+- [x] NIP-45: Counting results
+- [x] NIP-50: Keywords filter
+- [x] NIP-70: Protected Events
+
+## The unconventional
+
+### The binaries are fully self contained.
+
+It should just run in linux without having to worry about what you have on your system. I want to download and run. No docker. No dependency hell.
+
+I'm not bothering with other operating systems.
+
+### The relay is a full nostr citizen with it's own public and private keys.
+
+For example, you can see my relay's profile (wss://relay.laantungir.net) running here:
+
+[Primal link](https://primal.net/p/nprofile1qqswn2jsmm8lq8evas0v9vhqkdpn9nuujt90mtz60nqgsxndy66es4qjjnhr7)
+
+What this means in practice is that when you start the relay, it generates keys for itself, and for it's administrator (You can specify these if you wish)
+
+Now the program and the administrator can have verifed communication between the two, simply by using nostr events. For example, the administrator can send DMs to the relay, asking it's status, and changing it's configuration through any client that can handle nip17 DMs. The relay can also send notifications to the administrator about it's current status, or it can publish it's status on a regular schedule directly to NOSTR as kind-1 notes.
+
+Also included is a more standard administrative web front end. This front end communicates to the relay using an extensive api, which again is nostr events signed by the administrator. You can completely control the relay through signed nostr events.

+
+## Quick Start
+
+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):
+
+```bash
+# Static binary - works on all Linux distributions (no dependencies)
+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
+mv c-relay-v0.6.0-linux-x86_64-static c-relay
+```
+
+### 2. Start the Relay
+
+Simply run the binary - no configuration files needed:
+
+```bash
+./c-relay
+```
+
+On first startup, you'll see:
+- **Admin Private Key**: Save this securely! You'll need it for administration
+- **Relay Public Key**: Your relay's identity on the Nostr network
+- **Port Information**: Default is 8888, or the next available port
+
+### 3. Access the Web Interface
+
+Open your browser and navigate to:
+```
+http://localhost:8888/api/
+```
+
+The web interface provides:
+- Real-time configuration management
+- Database statistics dashboard
+- Auth rules management
+- Secure admin authentication with your Nostr identity
+
+### 4. Test Your Relay
+
+Test basic connectivity:
+```bash
+# Test WebSocket connection
+curl -H "Accept: application/nostr+json" http://localhost:8888
+
+# Test with a Nostr client
+# Add ws://localhost:8888 to your client's relay list
+```
+
+### 5. Configure Your Relay (Optional)
+
+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.
+
+### Admin Commands
+
+All commands are sent as NIP-44 encrypted JSON arrays in the event content. The following table lists all available commands:
+
+| Command Type | Command Format | Description |
+|--------------|----------------|-------------|
+| **Configuration Management** |
+| `config_update` | `["config_update", [{"key": "auth_enabled", "value": "true", "data_type": "boolean", "category": "auth"}, {"key": "relay_description", "value": "My Relay", "data_type": "string", "category": "relay"}, ...]]` | Update relay configuration parameters (supports multiple updates) |
+| `config_query` | `["config_query", "all"]` | Query all configuration parameters |

+
+### 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.
+

+
+### SQL Query Command
+
+The `sql_query` command allows administrators to execute read-only SQL queries against the relay database. This provides powerful analytics and debugging capabilities through the admin API.
+
+**Request/Response Correlation:**
+- Each response includes the request event ID in both the `tags` array (`["e", "request_event_id"]`) and the decrypted content (`"request_id": "request_event_id"`)
+- This allows proper correlation when multiple queries are submitted concurrently
+- Frontend can track pending queries and match responses to requests
+
+**Security Features:**
+- Only SELECT statements allowed (INSERT, UPDATE, DELETE, DROP, etc. are blocked)
+- Query timeout: 5 seconds (configurable)
+- Result row limit: 1000 rows (configurable)
+- All queries logged with execution time
+
+**Available Tables and Views:**
+- `events` - All Nostr events
+- `config` - Configuration parameters
+- `auth_rules` - Authentication rules
+- `subscription_events` - Subscription lifecycle log
+- `event_broadcasts` - Event broadcast log
+- `recent_events` - Last 1000 events (view)
+- `event_stats` - Event statistics by type (view)
+- `subscription_analytics` - Subscription metrics (view)
+- `active_subscriptions_log` - Currently active subscriptions (view)
+- `event_kinds_view` - Event distribution by kind (view)
+- `top_pubkeys_view` - Top 10 pubkeys by event count (view)
+- `time_stats_view` - Time-based statistics (view)
+
+**Example Queries:**
+```sql
+-- Recent events
+SELECT id, pubkey, created_at, kind FROM events ORDER BY created_at DESC LIMIT 20
+
+-- Event distribution by kind
+SELECT * FROM event_kinds_view ORDER BY count DESC
+
+-- Active subscriptions
+SELECT * FROM active_subscriptions_log ORDER BY created_at DESC
+
+-- Database statistics
+SELECT
+  (SELECT COUNT(*) FROM events) as total_events,
+  (SELECT COUNT(*) FROM subscription_events) as total_subscriptions
+```
+
+
+
+
+
+
+## Real-time Monitoring System
+
+C-Relay includes a subscription-based monitoring system that broadcasts real-time relay statistics using ephemeral events (kind 24567).
+
+### Activation
+
+The monitoring system activates automatically when clients subscribe to kind 24567 events:
+
+```json
+["REQ", "monitoring-sub", {"kinds": [24567]}]
+```
+
+For specific monitoring types, use d-tag filters:
+
+```json
+["REQ", "event-kinds-sub", {"kinds": [24567], "#d": ["event_kinds"]}]
+["REQ", "time-stats-sub", {"kinds": [24567], "#d": ["time_stats"]}]
+["REQ", "top-pubkeys-sub", {"kinds": [24567], "#d": ["top_pubkeys"]}]
+```
+
+When no subscriptions exist, monitoring is dormant to conserve resources.
+
+### Monitoring Event Types
+
+| Type | d Tag | Description |
+|------|-------|-------------|
+| Event Distribution | `event_kinds` | Event count by kind with percentages |
+| Time Statistics | `time_stats` | Events in last 24h, 7d, 30d |
+| Top Publishers | `top_pubkeys` | Top 10 pubkeys by event count |
+| Active Subscriptions | `active_subscriptions` | Current subscription details (admin only) |
+| Subscription Details | `subscription_details` | Detailed subscription info (admin only) |
+| CPU Metrics | `cpu_metrics` | Process CPU and memory usage |
+
+### Event Structure
+
+```json
+{
+  "kind": 24567,
+  "pubkey": "<relay_pubkey>",
+  "created_at": <timestamp>,
+  "content": "{\"data_type\":\"event_kinds\",\"timestamp\":1234567890,...}",
+  "tags": [
+    ["d", "event_kinds"]
+  ]
+}
+```
+
+### Configuration
+
+- `kind_24567_reporting_throttle_sec`: Minimum seconds between monitoring events (default: 5)
+
+### Web Dashboard Integration
+
+The built-in web dashboard (`/api/`) automatically subscribes to monitoring events and displays real-time statistics.
+
+### Performance Considerations
+
+- Monitoring events are ephemeral (not stored in database)
+- Throttling prevents excessive event generation
+- Automatic activation/deactivation based on subscriptions
+- Minimal overhead when no clients are monitoring
+
+##  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

-# C Nostr Relay Database
-
-This directory contains the SQLite database schema and initialization scripts for the C Nostr Relay implementation.
-
-## Files
-
-- **`schema.sql`** - Complete database schema based on nostr-rs-relay v18
-- **`init.sh`** - Database initialization script
-- **`c_nostr_relay.db`** - SQLite database file (created after running init.sh)
-
-## Quick Start
-
-1. **Initialize the database:**
-   ```bash
-   cd db
-   ./init.sh
-   ```
-
-2. **Force reinitialize (removes existing database):**
-   ```bash
-   ./init.sh --force
-   ```
-
-3. **Initialize with optimization and info:**
-   ```bash
-   ./init.sh --info --optimize
-   ```
-
-## Database Schema
-
-The schema is fully compatible with the Nostr protocol and includes:
-
-### Core Tables
-
-- **`event`** - Main event storage with all Nostr event data
-- **`tag`** - Denormalized tag index for efficient queries
-- **`user_verification`** - NIP-05 verification tracking
-- **`account`** - User account management (optional)
-- **`invoice`** - Lightning payment tracking (optional)
-
-### Key Features
-
-- ✅ **NIP-01 compliant** - Full basic protocol support
-- ✅ **Replaceable events** - Supports kinds 0, 3, 10000-19999
-- ✅ **Parameterized replaceable** - Supports kinds 30000-39999 with `d` tags
-- ✅ **Event deletion** - NIP-09 soft deletion with `hidden` column
-- ✅ **Event expiration** - NIP-40 automatic cleanup
-- ✅ **Authentication** - NIP-42 client authentication
-- ✅ **NIP-05 verification** - Domain-based identity verification
-- ✅ **Performance optimized** - Comprehensive indexing strategy
-
-### Schema Version
-
-Current version: **v18** (compatible with nostr-rs-relay v18)
-
-## Database Structure
-
-### Event Storage
-```sql
-CREATE TABLE event (
-    id INTEGER PRIMARY KEY,
-    event_hash BLOB NOT NULL,        -- 32-byte SHA256 hash
-    first_seen INTEGER NOT NULL,     -- relay receive timestamp
-    created_at INTEGER NOT NULL,     -- event creation timestamp
-    expires_at INTEGER,              -- NIP-40 expiration
-    author BLOB NOT NULL,            -- 32-byte pubkey
-    delegated_by BLOB,               -- NIP-26 delegator
-    kind INTEGER NOT NULL,           -- event kind
-    hidden INTEGER DEFAULT FALSE,   -- soft deletion flag
-    content TEXT NOT NULL            -- complete JSON event
-);
-```
-
-### Tag Indexing
-```sql
-CREATE TABLE tag (
-    id INTEGER PRIMARY KEY,
-    event_id INTEGER NOT NULL,
-    name TEXT,                       -- tag name ("e", "p", etc.)
-    value TEXT,                      -- tag value
-    created_at INTEGER NOT NULL,     -- denormalized for performance
-    kind INTEGER NOT NULL            -- denormalized for performance
-);
-```
-
-## Performance Features
-
-### Optimized Indexes
-- **Hash-based lookups** - `event_hash_index` for O(1) event retrieval
-- **Author queries** - `author_index`, `author_created_at_index`
-- **Kind filtering** - `kind_index`, `kind_created_at_index`
-- **Tag searching** - `tag_covering_index` for efficient tag queries
-- **Composite queries** - Multi-column indexes for complex filters
-
-### Query Optimization
-- **Denormalized tags** - Includes `kind` and `created_at` in tag table
-- **Binary storage** - BLOBs for hex data (pubkeys, hashes)
-- **WAL mode** - Write-Ahead Logging for concurrent access
-- **Automatic cleanup** - Triggers for data integrity
-
-## Usage Examples
-
-### Basic Operations
-
-1. **Insert an event:**
-   ```sql
-   INSERT INTO event (event_hash, first_seen, created_at, author, kind, content)
-   VALUES (?, ?, ?, ?, ?, ?);
-   ```
-
-2. **Query by author:**
-   ```sql
-   SELECT content FROM event 
-   WHERE author = ? AND hidden != TRUE
-   ORDER BY created_at DESC;
-   ```
-
-3. **Filter by tags:**
-   ```sql
-   SELECT e.content FROM event e
-   JOIN tag t ON e.id = t.event_id
-   WHERE t.name = 'p' AND t.value = ? AND e.hidden != TRUE;
-   ```
-
-### Advanced Queries
-
-1. **Get replaceable event (latest only):**
-   ```sql
-   SELECT content FROM event
-   WHERE author = ? AND kind = ? AND hidden != TRUE
-   ORDER BY created_at DESC LIMIT 1;
-   ```
-
-2. **Tag-based filtering (NIP-01 filters):**
-   ```sql
-   SELECT e.content FROM event e
-   WHERE e.id IN (
-     SELECT t.event_id FROM tag t
-     WHERE t.name = ? AND t.value IN (?, ?, ?)
-   ) AND e.hidden != TRUE;
-   ```
-
-## Maintenance
-
-### Regular Operations
-
-1. **Check database integrity:**
-   ```bash
-   sqlite3 c_nostr_relay.db "PRAGMA integrity_check;"
-   ```
-
-2. **Optimize database:**
-   ```bash
-   sqlite3 c_nostr_relay.db "PRAGMA optimize; VACUUM; ANALYZE;"
-   ```
-
-3. **Clean expired events:**
-   ```sql
-   DELETE FROM event WHERE expires_at <= strftime('%s', 'now');
-   ```
-
-### Monitoring
-
-1. **Database size:**
-   ```bash
-   ls -lh c_nostr_relay.db
-   ```
-
-2. **Table statistics:**
-   ```sql
-   SELECT name, COUNT(*) as count FROM (
-     SELECT 'events' as name FROM event UNION ALL
-     SELECT 'tags' as name FROM tag UNION ALL
-     SELECT 'verifications' as name FROM user_verification
-   ) GROUP BY name;
-   ```
-
-## Migration Support
-
-The schema includes a migration system for future updates:
-
-```sql
-CREATE TABLE schema_info (
-    version INTEGER PRIMARY KEY,
-    applied_at INTEGER NOT NULL,
-    description TEXT
-);
-```
-
-## Security Considerations
-
-1. **Input validation** - Always validate event JSON and signatures
-2. **Rate limiting** - Implement at application level
-3. **Access control** - Use `account` table for permissions
-4. **Backup strategy** - Regular database backups recommended
-
-## Compatibility
-
-- **SQLite version** - Requires SQLite 3.8.0+
-- **nostr-rs-relay** - Schema compatible with v18
-- **NIPs supported** - 01, 02, 05, 09, 10, 11, 26, 40, 42
-- **C libraries** - Compatible with sqlite3 C API
-
-## Troubleshooting
-
-### Common Issues
-
-1. **Database locked error:**
-   - Ensure proper connection closing in your C code
-   - Check for long-running transactions
-
-2. **Performance issues:**
-   - Run `PRAGMA optimize;` regularly
-   - Consider `VACUUM` if database grew significantly
-
-3. **Schema errors:**
-   - Verify SQLite version compatibility
-   - Check foreign key constraints
-
-### Getting Help
-
-- Check the main project README for C implementation details
-- Review nostr-rs-relay documentation for reference implementation
-- Consult Nostr NIPs for protocol specifications

+# 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

+
+## 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 Utilities (`string_utils.h`)
+- Safe string operations (bounds checking)
+- String trimming, splitting, joining
+- Case conversion
+- Pattern matching helpers
+
+### Memory Utilities (`memory_utils.h`)
+- Safe allocation wrappers
+- Memory pool management
+- Leak detection helpers (debug builds)
+- Arena allocators
+
+### Configuration Utilities (`config_utils.h`)
+- INI file parsing
+- JSON configuration (using cJSON)
+- Environment variable helpers
+- Command-line argument parsing
+
+### File Utilities (`file_utils.h`)
+- Safe file operations
+- Directory traversal
+- Path manipulation
+- File watching (inotify wrapper)
+
+### Time Utilities (`time_utils.h`)
+- Timestamp formatting
+- Duration calculations
+- Timer utilities
+- Rate limiting helpers
+
+## 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

+
+.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)

+        make test
+        ;;
+    clean)
+        echo "Cleaning..."
+        make clean

+    *)
+        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

+
+## Overview
+
+The C Nostr Relay uses a revolutionary **event-based configuration system** where all settings are stored as kind 33334 Nostr events in the database. This provides several advantages:
+
+### Benefits
+- **Real-time updates**: Configuration changes applied instantly without restart
+- **Cryptographic security**: All changes must be cryptographically signed by admin
+- **Audit trail**: Complete history of all configuration changes
+- **Version control**: Each configuration change is timestamped and signed
+- **Zero files**: No configuration files to manage, backup, or version control
+
+### How It Works
+1. **Admin keypair**: Generated on first startup, used to sign configuration events
+2. **Configuration events**: Kind 33334 Nostr events with relay settings in tags
+3. **Real-time processing**: New configuration events processed via WebSocket
+4. **Immediate application**: Changes applied to running system without restart
+
+## Configuration Events
+
+### Event Structure
+
+Configuration events follow the standard Nostr event format with kind 33334:
+
+```json
+{
+  "id": "event_id_computed_from_content",
+  "kind": 33334,
+  "pubkey": "admin_public_key_hex",
+  "created_at": 1699123456,
+  "content": "C Nostr Relay Configuration",
+  "tags": [
+    ["d", "relay_public_key_hex"],
+    ["relay_description", "My Nostr Relay"],
+    ["max_subscriptions_per_client", "25"],
+    ["pow_min_difficulty", "16"]
+  ],
+  "sig": "signature_computed_with_admin_private_key"
+}
+```
+
+### Required Tags
+- **`d` tag**: Must contain the relay's public key (identifies which relay this config is for)
+
+### Event Properties
+- **Kind**: Must be exactly `33334`
+- **Content**: Should be descriptive (e.g., "C Nostr Relay Configuration")
+- **Pubkey**: Must be the admin public key generated at first startup
+- **Signature**: Must be valid signature from admin private key

+### Basic Relay Setup
+```json
+{
+  "kind": 33334,
+  "content": "Basic Relay Configuration",
+  "tags": [
+    ["d", "relay_pubkey_here"],
+    ["relay_description", "Community Nostr Relay"],
+    ["relay_contact", "admin@community-relay.com"],
+    ["max_subscriptions_per_client", "30"],
+    ["max_total_subscriptions", "8000"]
+  ]
+}
+```
+

+  "content": "High Security Configuration",
+  "tags": [
+    ["d", "relay_pubkey_here"],
+    ["relay_description", "High-Security Nostr Relay"],
+    ["pow_min_difficulty", "24"],
+    ["pow_mode", "required"],
+    ["max_subscriptions_per_client", "10"],
+    ["max_total_subscriptions", "1000"],
+    ["max_message_length", "32768"],
+    ["nip40_expiration_strict", "true"]
+  ]
+}
+```
+
+### Public Community Relay
+```json
+{
+  "kind": 33334,
+  "content": "Public Community Relay Configuration",
+  "tags": [
+    ["d", "relay_pubkey_here"],
+    ["relay_description", "Open Community Relay - Welcome Everyone!"],
+    ["relay_contact", "community@relay.example"],
+    ["max_subscriptions_per_client", "50"],
+    ["max_total_subscriptions", "25000"],
+    ["max_content_length", "131072"],
+    ["pow_mode", "optional"],
+    ["pow_min_difficulty", "8"],
+    ["nip40_expiration_enabled", "true"],
+    ["nip40_expiration_grace_period", "900"]
+  ]
+}
+```
+
+### Private/Corporate Relay
+```json
+{
+  "kind": 33334,
+  "content": "Corporate Internal Relay",
+  "tags": [
+    ["d", "relay_pubkey_here"],
+    ["relay_description", "Corporate Internal Communications"],
+    ["relay_contact", "it-admin@company.com"],

+    ["nip40_expiration_enabled", "false"],
+    ["pow_mode", "disabled"]
+  ]
+}
+```
+
+## Security Considerations
+
+### Admin Key Management
+
+#### Secure Storage
+```bash
+# Store admin private key securely
+echo "ADMIN_PRIVKEY=your_admin_private_key_here" > .env
+chmod 600 .env
+
+# Or use a password manager
+# Never store in version control
+echo ".env" >> .gitignore
+```
+
+#### Key Rotation
+Currently, admin key rotation requires:
+1. Stopping the relay
+2. Removing the database (loses all events)
+3. Restarting (generates new keys)
+
+Future versions will support admin key rotation while preserving events.
+
+### Event Validation
+
+The relay performs comprehensive validation on configuration events:
+
+#### Cryptographic Validation
+- **Signature verification**: Uses `nostr_verify_event_signature()`
+- **Event structure**: Validates JSON structure with `nostr_validate_event_structure()`
+- **Admin authorization**: Ensures events are signed by the authorized admin pubkey
+
+#### Content Validation
+- **Parameter bounds checking**: Validates numeric ranges
+- **String length limits**: Enforces maximum lengths
+- **Enum validation**: Validates allowed values for mode parameters
+
+### Network Security
+
+#### Access Control
+```bash
+# Limit access with firewall
+sudo ufw allow from 192.168.1.0/24 to any port 8888
+
+# Or use specific IPs
+sudo ufw allow from 203.0.113.10 to any port 8888
+```
+
+#### TLS/SSL Termination
+```nginx
+# nginx configuration for HTTPS termination
+server {
+    listen 443 ssl;
+    server_name relay.example.com;
+    
+    ssl_certificate /path/to/cert.pem;
+    ssl_certificate_key /path/to/key.pem;
+    
+    location / {
+        proxy_pass http://127.0.0.1:8888;
+        proxy_http_version 1.1;
+        proxy_set_header Upgrade $http_upgrade;
+        proxy_set_header Connection "Upgrade";
+        proxy_set_header Host $host;
+    }
+}
+```
+
+## Troubleshooting
+
+### Configuration Not Applied
+
+#### Check Event Signature
+```javascript
+// Verify event signature with nostrtool or similar
+const event = { /* your configuration event */ };
+const isValid = nostrTools.verifySignature(event);
+```
+
+#### Verify Admin Pubkey
+```bash
+# Check current admin pubkey in database
+sqlite3 relay.nrdb "SELECT DISTINCT pubkey FROM events WHERE kind = 33334 ORDER BY created_at DESC LIMIT 1;"
+
+# Compare with expected admin pubkey from first startup
+grep "Admin Public Key" relay.log
+```
+
+#### Check Event Structure
+```bash
+# View the exact event stored in database
+sqlite3 relay.nrdb "SELECT json_pretty(json_object(
+  'kind', kind,
+  'pubkey', pubkey, 
+  'created_at', created_at,
+  'content', content,
+  'tags', json(tags),
+  'sig', sig
+)) FROM events WHERE kind = 33334 ORDER BY created_at DESC LIMIT 1;"
+```
+
+### Configuration Validation Errors
+
+#### Invalid Parameter Values
+```bash
+# Check relay logs for validation errors
+journalctl -u c-relay | grep "Configuration.*invalid\|Invalid.*configuration"
+
+# Common issues:
+# - Numeric values outside valid ranges
+# - Invalid enum values (e.g., pow_mode)
+# - String values exceeding length limits
+```
+
+#### Missing Required Tags
+```bash
+# Ensure 'd' tag is present with relay pubkey
+sqlite3 relay.nrdb "SELECT tags FROM events WHERE kind = 33334 ORDER BY created_at DESC LIMIT 1;" | grep '"d"'
+```
+
+### Performance Impact
+
+#### Monitor Configuration Changes
+```bash
+# Track configuration update frequency
+sqlite3 relay.nrdb "SELECT datetime(created_at, 'unixepoch') as date, 
+  COUNT(*) as config_updates 
+FROM events WHERE kind = 33334 
+GROUP BY date(created_at, 'unixepoch') 
+ORDER BY date DESC;"
+```
+
+#### Resource Usage After Changes
+```bash
+# Monitor system resources after configuration updates
+top -p $(pgrep c_relay)
+
+# Check for memory leaks
+ps aux | grep c_relay | awk '{print $6}' # RSS memory
+```
+
+### Emergency Recovery
+
+#### Reset to Default Configuration
+If configuration becomes corrupted or causes issues:
+
+```bash
+# Create emergency configuration event
+nostrtool event \
+  --kind 33334 \
+  --content "Emergency Reset Configuration" \
+  --tag d YOUR_RELAY_PUBKEY \
+  --tag max_subscriptions_per_client 25 \
+  --tag max_total_subscriptions 5000 \
+  --tag pow_mode optional \
+  --tag pow_min_difficulty 0 \
+  --private-key YOUR_ADMIN_PRIVKEY \
+  | nostrtool send ws://localhost:8888
+```
+
+#### Database Recovery
+```bash
+# If database is corrupted, backup and recreate
+cp relay.nrdb relay.nrdb.backup
+rm relay.nrdb*
+./build/c_relay_x86  # Creates fresh database with new keys
+```
+

+# 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`)

+    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.

+
+1. **Isolation**: These default values are completely isolated from the rest of the program
+2. **Single Access Point**: Only accessed during `create_default_config_event()`
+3. **Runtime Keys**: Relay keys are added at runtime, not stored as defaults
+4. **No Direct Access**: Other parts of the program should never include this header directly
+5. **Clean Separation**: Keeps default configuration separate from configuration logic
+
+## Function Implementation
+
+The `create_default_config_event()` function will:
+
+1. Create a new cJSON event object with kind 33334
+2. Add all default configuration values as tags
+3. Add runtime-generated relay keys as tags
+4. Use `nostr_core_lib` to sign the event with admin private key
+5. Return the complete signed event ready for database storage
+
+This approach ensures clean separation between default values and the configuration system logic.

+sudo apt update && sudo apt upgrade -y
+
+# CentOS/RHEL
+sudo yum update -y
+
+# Install required packages
+sudo apt install -y build-essential git sqlite3 libsqlite3-dev \
+    libwebsockets-dev libssl-dev libsecp256k1-dev libcurl4-openssl-dev \
+    zlib1g-dev systemd
+```
+
+#### User and Directory Setup
+```bash
+# Create dedicated system user
+sudo useradd --system --home-dir /opt/c-relay --shell /bin/false c-relay
+
+# Create application directory
+sudo mkdir -p /opt/c-relay
+sudo chown c-relay:c-relay /opt/c-relay
+```
+
+### Build and Installation
+
+#### Automated Installation (Recommended)
+```bash
+# Clone repository
+git clone https://github.com/your-org/c-relay.git
+cd c-relay
+git submodule update --init --recursive
+
+# Build
+make clean && make
+
+# Install as systemd service
+sudo systemd/install-service.sh
+```
+
+#### Manual Installation
+```bash
+# Build relay
+make clean && make
+
+# Install binary
+sudo cp build/c_relay_x86 /opt/c-relay/
+sudo chown c-relay:c-relay /opt/c-relay/c_relay_x86
+sudo chmod +x /opt/c-relay/c_relay_x86
+
+# Install systemd service
+sudo cp systemd/c-relay.service /etc/systemd/system/
+sudo systemctl daemon-reload
+```
+
+### Service Management
+
+#### Start and Enable Service
+```bash
+# Start the service
+sudo systemctl start c-relay
+
+# Enable auto-start on boot
+sudo systemctl enable c-relay

+
+# Or check the full log
+sudo journalctl -u c-relay --no-pager | grep "Admin Private Key"
+```
+
+⚠️ **CRITICAL**: Save the admin private key immediately - it's only shown once and is needed for all configuration updates!
+
+### Firewall Configuration
+
+#### UFW (Ubuntu)
+```bash
+# Allow relay port
+sudo ufw allow 8888/tcp
+
+# Allow SSH (ensure you don't lock yourself out)

+sudo chmod 700 /opt/c-relay
+sudo chown -R c-relay:c-relay /opt/c-relay
+```
+
+#### File System Restrictions
+```bash
+# Mount data directory with appropriate options
+echo "/dev/sdb /opt/c-relay ext4 defaults,noexec,nosuid,nodev 0 2" >> /etc/fstab
+```
+
+### Network Security
+
+#### Fail2Ban Configuration
+```ini
+# /etc/fail2ban/jail.d/c-relay.conf
+[c-relay-dos]
+enabled = true
+port = 8888
+filter = c-relay-dos
+logpath = /var/log/c-relay.log
+maxretry = 10
+findtime = 60
+bantime = 300
+```
+
+#### DDoS Protection
+```bash
+# iptables rate limiting
+sudo iptables -A INPUT -p tcp --dport 8888 -m limit --limit 25/minute --limit-burst 100 -j ACCEPT
+sudo iptables -A INPUT -p tcp --dport 8888 -j DROP
+```
+
+### Database Security
+
+#### Encryption at Rest
+```bash
+# Use encrypted filesystem
+sudo cryptsetup luksFormat /dev/sdb
+sudo cryptsetup luksOpen /dev/sdb relay-data
+sudo mkfs.ext4 /dev/mapper/relay-data
+```
+
+## Backup and Recovery
+
+### Automated Backup
+
+#### Database Backup Script
+```bash
+#!/bin/bash
+# /usr/local/bin/backup-relay.sh
+
+BACKUP_DIR="/backup/c-relay"
+DATE=$(date +%Y%m%d_%H%M%S)
+RELAY_DB=$(find /opt/c-relay -name "*.nrdb" | head -1)
+
+mkdir -p "$BACKUP_DIR"
+
+if [[ -n "$RELAY_DB" ]]; then
+    # SQLite backup
+    sqlite3 "$RELAY_DB" ".backup $BACKUP_DIR/relay_backup_$DATE.nrdb"
+    
+    # Compress backup
+    gzip "$BACKUP_DIR/relay_backup_$DATE.nrdb"

+# Libwebsockets Proper Pattern - Message Queue Design
+
+## Problem Analysis
+
+### Current Violation
+We're calling `lws_write()` directly from multiple code paths:
+1. **Event broadcast** (subscriptions.c:667) - when events arrive
+2. **OK responses** (websockets.c:855) - when processing EVENT messages
+3. **EOSE responses** (websockets.c:976) - when processing REQ messages
+4. **COUNT responses** (websockets.c:1922) - when processing COUNT messages
+
+This violates libwebsockets' design pattern which requires:
+- **`lws_write()` ONLY called from `LWS_CALLBACK_SERVER_WRITEABLE`**
+- Application queues messages and requests writeable callback
+- Libwebsockets handles write timing and socket buffer management
+
+### Consequences of Violation
+1. Partial writes when socket buffer is full
+2. Multiple concurrent write attempts before callback fires
+3. "write already pending" errors with single buffer
+4. Frame corruption from interleaved partial writes
+5. "Invalid frame header" errors on client side
+
+## Correct Architecture
+
+### Message Queue Pattern

+                    - Partial write handling
+                    - Frame atomicity
+```
+
+## Data Structures
+
+### Message Queue Node
+```c
+typedef struct message_queue_node {
+    unsigned char* data;           // Message data (with LWS_PRE space)
+    size_t length;                 // Message length (without LWS_PRE)
+    enum lws_write_protocol type;  // LWS_WRITE_TEXT, etc.
+    struct message_queue_node* next;
+} message_queue_node_t;
+```
+
+### Per-Session Data Updates
+```c
+struct per_session_data {
+    // ... existing fields ...
+    
+    // Message queue (replaces single buffer)
+    message_queue_node_t* message_queue_head;
+    message_queue_node_t* message_queue_tail;
+    int message_queue_count;
+    int writeable_requested;  // Flag to prevent duplicate requests
+};
+```
+
+## Implementation Functions
+
+### 1. Queue Message (Application Layer)
+```c
+int queue_message(struct lws* wsi, struct per_session_data* pss,
+                  const char* message, size_t length,
+                  enum lws_write_protocol type)
+{
+    // Allocate node
+    message_queue_node_t* node = malloc(sizeof(message_queue_node_t));
+    
+    // Allocate buffer with LWS_PRE space
+    node->data = malloc(LWS_PRE + length);
+    memcpy(node->data + LWS_PRE, message, length);
+    node->length = length;
+    node->type = type;
+    node->next = NULL;
+    
+    // Add to queue (FIFO)
+    pthread_mutex_lock(&pss->session_lock);
+    if (!pss->message_queue_head) {
+        pss->message_queue_head = node;
+        pss->message_queue_tail = node;
+    } else {
+        pss->message_queue_tail->next = node;
+        pss->message_queue_tail = node;
+    }
+    pss->message_queue_count++;
+    pthread_mutex_unlock(&pss->session_lock);
+    
+    // Request writeable callback (only if not already requested)
+    if (!pss->writeable_requested) {
+        pss->writeable_requested = 1;
+        lws_callback_on_writable(wsi);
+    }
+    
+    return 0;
+}
+```
+
+### 2. Process Queue (Writeable Callback)
+```c
+int process_message_queue(struct lws* wsi, struct per_session_data* pss)
+{
+    pthread_mutex_lock(&pss->session_lock);
+    
+    // Get next message from queue
+    message_queue_node_t* node = pss->message_queue_head;
+    if (!node) {
+        pss->writeable_requested = 0;
+        pthread_mutex_unlock(&pss->session_lock);
+        return 0;  // Queue empty
+    }
+    
+    // Remove from queue
+    pss->message_queue_head = node->next;
+    if (!pss->message_queue_head) {
+        pss->message_queue_tail = NULL;
+    }
+    pss->message_queue_count--;
+    
+    pthread_mutex_unlock(&pss->session_lock);
+    
+    // Write message (libwebsockets handles partial writes)
+    int result = lws_write(wsi, node->data + LWS_PRE, node->length, node->type);
+    
+    // Free node
+    free(node->data);
+    free(node);
+    
+    // If queue not empty, request another callback
+    pthread_mutex_lock(&pss->session_lock);
+    if (pss->message_queue_head) {
+        lws_callback_on_writable(wsi);
+    } else {
+        pss->writeable_requested = 0;
+    }
+    pthread_mutex_unlock(&pss->session_lock);
+    
+    return (result < 0) ? -1 : 0;
+}
+```
+
+## Refactoring Changes
+
+### Before (WRONG - Direct Write)
+```c
+// websockets.c:855 - OK response
+int write_result = lws_write(wsi, buf + LWS_PRE, response_len, LWS_WRITE_TEXT);
+if (write_result < 0) {
+    DEBUG_ERROR("Write failed");
+} else if ((size_t)write_result != response_len) {
+    // Partial write - queue remaining data
+    queue_websocket_write(wsi, pss, ...);
+}
+```
+
+### After (CORRECT - Queue Message)
+```c
+// websockets.c:855 - OK response
+queue_message(wsi, pss, response_str, response_len, LWS_WRITE_TEXT);
+// That's it! Writeable callback will handle the actual write
+```
+
+### Before (WRONG - Direct Write in Broadcast)
+```c
+// subscriptions.c:667 - EVENT broadcast
+int write_result = lws_write(current_temp->wsi, buf + LWS_PRE, msg_len, LWS_WRITE_TEXT);
+if (write_result < 0) {
+    DEBUG_ERROR("Write failed");
+} else if ((size_t)write_result != msg_len) {
+    queue_websocket_write(...);
+}
+```
+
+### After (CORRECT - Queue Message)
+```c
+// subscriptions.c:667 - EVENT broadcast
+struct per_session_data* pss = lws_wsi_user(current_temp->wsi);
+queue_message(current_temp->wsi, pss, msg_str, msg_len, LWS_WRITE_TEXT);
+// Writeable callback will handle the actual write
+```
+
+## Benefits of Correct Pattern
+
+1. **No Partial Write Handling Needed**
+   - Libwebsockets handles partial writes internally
+   - We just queue complete messages
+
+2. **No "Write Already Pending" Errors**
+   - Queue can hold unlimited messages
+   - Each processed sequentially from callback
+
+3. **Thread Safety**
+   - Queue operations protected by session lock
+   - Write only from single callback thread
+
+4. **Frame Atomicity**
+   - Libwebsockets ensures complete frame transmission
+   - No interleaved partial writes
+
+5. **Simpler Code**
+   - No complex partial write state machine
+   - Just queue and forget
+
+6. **Better Performance**
+   - Libwebsockets optimizes write timing
+   - Batches writes when socket ready
+
+## Migration Steps

+1. ✅ Identify all `lws_write()` call sites
+2. ✅ Confirm violation of libwebsockets pattern
+3. ⏳ Design message queue structure

+9. ⏳ Refactor COUNT response to use queue
+10. ⏳ Refactor EVENT broadcast to use queue
+11. ⏳ Update `LWS_CALLBACK_SERVER_WRITEABLE` handler
+12. ⏳ Add queue cleanup in `LWS_CALLBACK_CLOSED`
+13. ⏳ Remove old partial write code
+14. ⏳ Test with rapid multiple events
+15. ⏳ Test with large events (>4KB)
+16. ⏳ Test under load
+17. ⏳ Verify no frame errors
+
+## Testing Strategy
+
+### Test 1: Multiple Rapid Events
+```bash
+# Send 10 events rapidly to same client
+for i in {1..10}; do
+    echo '["EVENT",{"kind":1,"content":"test'$i'","created_at":'$(date +%s)',...}]' | \
+    websocat ws://localhost:8888 &
+done
+```
+
+**Expected**: All events queued and sent sequentially, no errors
+
+### Test 2: Large Events
+```bash
+# Send event >4KB (forces multiple socket writes)
+nak event --content "$(head -c 5000 /dev/urandom | base64)" | \
+websocat ws://localhost:8888
+```
+
+**Expected**: Event queued, libwebsockets handles partial writes internally
+
+### Test 3: Concurrent Connections
+```bash
+# 100 concurrent connections, each sending events
+for i in {1..100}; do
+    (echo '["REQ","sub'$i'",{}]'; sleep 1) | websocat ws://localhost:8888 &
+done
+```
+
+**Expected**: All subscriptions work, events broadcast correctly
+
+## Success Criteria
+
+- ✅ No `lws_write()` calls outside `LWS_CALLBACK_SERVER_WRITEABLE`
+- ✅ No "write already pending" errors in logs
+- ✅ No "Invalid frame header" errors on client side
+- ✅ All messages delivered in correct order
+- ✅ Large events (>4KB) handled correctly
+- ✅ Multiple rapid events to same client work
+- ✅ Concurrent connections stable under load

+# Simplified Monitoring Implementation Plan
+## Kind 34567 Event Kind Distribution Reporting
+
+**Date:** 2025-10-16  
+**Status:** Implementation Ready
+
+---
+
+## Overview
+
+Simplified real-time monitoring system that:
+- Reports event kind distribution (which includes total event count)
+- Uses kind 34567 addressable events with `d=event_kinds`
+- Controlled by two config variables
+- Enabled on-demand when admin logs in
+- Uses simple throttling to prevent performance impact
+
+---
+
+## Configuration Variables
+
+### Database Config Table
+
+Add two new configuration keys:
+
+```sql
+INSERT INTO config (key, value, data_type, description, category) VALUES
+  ('kind_34567_reporting_enabled', 'false', 'boolean', 
+   'Enable/disable kind 34567 event kind distribution reporting', 'monitoring'),
+  ('kind_34567_reporting_throttling_sec', '5', 'integer', 
+   'Minimum seconds between kind 34567 reports (throttling)', 'monitoring');
+```
+
+### Configuration Access
+
+```c
+// In src/monitoring.c or src/api.c
+int is_monitoring_enabled(void) {
+    return get_config_bool("kind_34567_reporting_enabled", 0);
+}
+
+int get_monitoring_throttle_seconds(void) {
+    return get_config_int("kind_34567_reporting_throttling_sec", 5);
+}
+```
+
+---
+
+## Event Structure
+
+### Kind 34567 Event Format
+
+```json
+{
+  "id": "<event_id>",
+  "pubkey": "<relay_pubkey>",
+  "created_at": 1697123456,
+  "kind": 34567,
+  "content": "{\"data_type\":\"event_kinds\",\"timestamp\":1697123456,\"data\":{\"total_events\":125000,\"distribution\":[{\"kind\":1,\"count\":45000,\"percentage\":36.0},{\"kind\":3,\"count\":12500,\"percentage\":10.0}]}}",
+  "tags": [
+    ["d", "event_kinds"],
+    ["relay", "<relay_pubkey>"]
+  ],
+  "sig": "<signature>"
+}
+```
+
+### Content JSON Structure
+
+```json

+        DEBUG_ERROR("Failed to generate monitoring event");
+    }
+}
+```
+
+### 3. Integration: Modify `src/main.c`
+
+Add monitoring hook to event storage:
+
+```c
+// At top of file
+#include "monitoring.h"
+
+// In main() function, after init_database()
+if (init_monitoring_system() != 0) {
+    DEBUG_WARN("Failed to initialize monitoring system");
+    // Continue anyway - monitoring is optional
+}
+
+// In store_event() function, after successful storage
+int store_event(cJSON* event) {
+    // ... existing code ...
+    
+    if (rc != SQLITE_DONE) {
+        // ... error handling ...
+    }
+    
+    free(tags_json);
+    
+    // Trigger monitoring update
+    monitoring_on_event_stored();
+    
+    return 0;
+}
+
+// In cleanup section of main()
+cleanup_monitoring_system();
+```
+
+### 4. Admin API: Enable/Disable Monitoring
+
+Add admin command to enable monitoring (in `src/dm_admin.c` or `src/api.c`):
+
+```c
+// Handle admin command to enable monitoring
+if (strcmp(command, "enable_monitoring") == 0) {
+    set_monitoring_enabled(1);
+    send_nip17_response(sender_pubkey, 
+        "✅ Kind 34567 monitoring enabled", 
+        error_msg, sizeof(error_msg));
+    return 0;
+}
+
+// Handle admin command to disable monitoring
+if (strcmp(command, "disable_monitoring") == 0) {
+    set_monitoring_enabled(0);
+    send_nip17_response(sender_pubkey, 
+        "🔴 Kind 34567 monitoring disabled", 
+        error_msg, sizeof(error_msg));
+    return 0;
+}
+
+// Handle admin command to set throttle interval
+if (strncmp(command, "set_monitoring_throttle ", 24) == 0) {
+    int seconds = atoi(command + 24);
+    if (seconds >= 1 && seconds <= 3600) {
+        char value[16];
+        snprintf(value, sizeof(value), "%d", seconds);
+        update_config_in_table("kind_34567_reporting_throttling_sec", value);
+        
+        char response[128];
+        snprintf(response, sizeof(response), 
+            "✅ Monitoring throttle set to %d seconds", seconds);
+        send_nip17_response(sender_pubkey, response, error_msg, sizeof(error_msg));
+    }
+    return 0;
+}
+```
+
+---
+
+## Frontend Integration
+
+### Admin Dashboard Subscription
+
+```javascript
+// When admin logs in to dashboard
+async function enableMonitoring() {
+  // Send admin command to enable monitoring
+  await sendAdminCommand(['enable_monitoring']);
+  
+  // Subscribe to kind 34567 events
+  const subscription = {
+    kinds: [34567],
+    authors: [relayPubkey],
+    "#d": ["event_kinds"]
+  };
+  
+  relay.subscribe([subscription], {
+    onevent: (event) => {
+      handleMonitoringEvent(event);
+    }
+  });
+}
+
+// Handle incoming monitoring events
+function handleMonitoringEvent(event) {
+  const content = JSON.parse(event.content);
+  
+  if (content.data_type === 'event_kinds') {
+    updateEventKindsChart(content.data);
+    updateTotalEventsDisplay(content.data.total_events);
+  }
+}
+
+// When admin logs out or closes dashboard
+async function disableMonitoring() {
+  await sendAdminCommand(['disable_monitoring']);
+}
+```
+
+### Display Event Kind Distribution
+
+```javascript
+function updateEventKindsChart(data) {
+  const { total_events, distribution } = data;
+  
+  // Update total events display
+  document.getElementById('total-events').textContent = 
+    total_events.toLocaleString();
+  
+  // Update chart/table with distribution
+  const tableBody = document.getElementById('kind-distribution-table');
+  tableBody.innerHTML = '';
+  
+  distribution.forEach(item => {
+    const row = document.createElement('tr');
+    row.innerHTML = `
+      <td>Kind ${item.kind}</td>
+      <td>${item.count.toLocaleString()}</td>
+      <td>${item.percentage}%</td>
+    `;
+    tableBody.appendChild(row);
+  });
+}
+```
+
+---
+
+## Configuration Migration
+
+### Add to Schema or Migration Script
+
+```sql
+-- Add monitoring configuration
+INSERT INTO config (key, value, data_type, description, category) VALUES
+  ('kind_34567_reporting_enabled', 'false', 'boolean', 
+   'Enable/disable kind 34567 event kind distribution reporting', 'monitoring'),
+  ('kind_34567_reporting_throttling_sec', '5', 'integer', 
+   'Minimum seconds between kind 34567 reports (throttling)', 'monitoring');
+```
+
+Or add to existing config initialization in `src/config.c`.
+
+---
+
+## Testing
+
+### 1. Enable Monitoring
+
+```bash
+# Via admin command (NIP-17 DM)
+echo '["enable_monitoring"]' | nak event --kind 14 --content - ws://localhost:8888
+```
+
+### 2. Subscribe to Monitoring Events
+
+```bash
+# Subscribe to kind 34567 events
+nak req --kinds 34567 --authors <relay_pubkey> ws://localhost:8888
+```
+
+### 3. Generate Events
+
+```bash
+# Send some test events to trigger monitoring
+for i in {1..10}; do
+  nak event -c "Test event $i" ws://localhost:8888
+  sleep 1
+done
+```
+
+### 4. Verify Monitoring Events
+
+You should see kind 34567 events every 5 seconds (or configured throttle interval) with event kind distribution.
+
+---
+
+## Performance Impact
+
+### With 3 events/second (relay.damus.io scale)
+
+**Query execution**:
+- Frequency: Every 5 seconds (throttled)
+- Query time: ~700ms (for 1M events)
+- Overhead: 700ms / 5000ms = 14% (acceptable)
+
+**Per-event overhead**:
+- Check if enabled: < 0.01ms
+- Check throttle: < 0.01ms
+- Total: < 0.02ms per event (negligible)
+
+**Overall impact**: < 1% on event processing, 14% on query thread (separate from event processing)
+
+---
+
+## Future Enhancements
+
+Once this is working, easy to add:
+
+1. **More data types**: Add `d=connections`, `d=subscriptions`, etc.
+2. **Materialized counters**: Optimize queries for very large databases
+3. **Historical data**: Store monitoring events for trending
+4. **Alerts**: Trigger on thresholds (e.g., > 90% capacity)
+
+---
+
+## Summary
+
+This simplified plan provides:
+
+✅ **Single data type**: Event kind distribution (includes total events)  
+✅ **Two config variables**: Enable/disable and throttle control  
+✅ **On-demand activation**: Enabled when admin logs in  
+✅ **Simple throttling**: Prevents performance impact  
+✅ **Clean implementation**: ~200 lines of code  
+✅ **Easy to extend**: Add more data types later  
+
+**Estimated implementation time**: 4-6 hours
+
+**Files to create/modify**:
+- Create: `src/monitoring.h` (~30 lines)
+- Create: `src/monitoring.c` (~200 lines)
+- Modify: `src/main.c` (~10 lines)
+- Modify: `src/config.c` or migration (~5 lines)
+- Modify: `src/dm_admin.c` or `src/api.c` (~30 lines)
+- Create: `api/monitoring.js` (frontend, ~100 lines)
+
+**Total new code**: ~375 lines

+# 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

+# NIP-59 Timestamp Configuration Implementation Plan
+
+## Overview
+Add configurable timestamp randomization for NIP-59 gift wraps to improve compatibility with Nostr apps that don't implement timestamp randomization.
+
+## Problem Statement
+The NIP-59 protocol specifies that timestamps on gift wraps should have randomness to prevent time-analysis attacks. However, some Nostr platforms don't implement this, causing compatibility issues with direct messaging (NIP-17).
+
+## Solution
+Add a configuration parameter `nip59_timestamp_max_delay_sec` that controls the maximum random delay applied to timestamps:
+- **Value = 0**: Use current timestamp (no randomization) for maximum compatibility
+- **Value > 0**: Use random timestamp between now and N seconds ago
+- **Default = 0**: Maximum compatibility mode (no randomization)
+
+## Implementation Approach: Option B (Direct Parameter Addition)
+We chose Option B because:
+1. Explicit and stateless - value flows through call chain
+2. Thread-safe by design
+3. No global state needed in nostr_core_lib
+4. DMs are sent rarely, so database query per call is acceptable
+
+---
+
+## Detailed Implementation Steps
+
+### Phase 1: Configuration Setup in c-relay
+
+#### 1.1 Add Configuration Parameter
+**File:** `src/default_config_event.h`
+**Location:** Line 82 (after `trust_proxy_headers`)
+
+```c
+// NIP-59 Gift Wrap Timestamp Configuration
+{"nip59_timestamp_max_delay_sec", "0"}  // Default: 0 (no randomization for compatibility)
+```
+
+**Rationale:**
+- Default of 0 seconds (no randomization) for maximum compatibility
+- Placed after proxy settings, before closing brace
+- Follows existing naming convention
+
+#### 1.2 Add Configuration Validation
+**File:** `src/config.c`
+**Function:** `validate_config_field()` (around line 923)
+
+Add validation case:
+```c
+else if (strcmp(key, "nip59_timestamp_max_delay_sec") == 0) {
+    long value = strtol(value_str, NULL, 10);
+    if (value < 0 || value > 604800) {  // Max 7 days
+        snprintf(error_msg, error_size, 
+                 "nip59_timestamp_max_delay_sec must be between 0 and 604800 (7 days)");
+        return -1;
+    }
+}
+```
+
+**Rationale:**
+- 0 = no randomization (compatibility mode)
+- 604800 = 7 days maximum (reasonable upper bound)
+- Prevents negative values or excessive delays
+
+---
+
+### Phase 2: Modify nostr_core_lib Functions
+
+#### 2.1 Update random_past_timestamp() Function
+**File:** `nostr_core_lib/nostr_core/nip059.c`
+**Current Location:** Lines 31-36
+
+**Current Code:**
+```c
+static time_t random_past_timestamp(void) {
+    time_t now = time(NULL);
+    // Random time up to 2 days (172800 seconds) in the past
+    long random_offset = (long)(rand() % 172800);
+    return now - random_offset;
+}
+```
+
+**New Code:**
+```c
+static time_t random_past_timestamp(long max_delay_sec) {
+    time_t now = time(NULL);
+    
+    // If max_delay_sec is 0, return current timestamp (no randomization)
+    if (max_delay_sec == 0) {
+        return now;
+    }
+    
+    // Random time up to max_delay_sec in the past
+    long random_offset = (long)(rand() % max_delay_sec);
+    return now - random_offset;
+}
+```
+
+**Changes:**
+- Add `long max_delay_sec` parameter
+- Handle special case: `max_delay_sec == 0` returns current time
+- Use `max_delay_sec` instead of hardcoded 172800
+
+#### 2.2 Update nostr_nip59_create_seal() Function
+**File:** `nostr_core_lib/nostr_core/nip059.c`
+**Current Location:** Lines 144-215
+
+**Function Signature Change:**

+```
+
+**Code Change at Line 181:**
+```c
+// OLD:

+```
+
+#### 2.3 Update nostr_nip59_create_gift_wrap() Function
+**File:** `nostr_core_lib/nostr_core/nip059.c`

+                                    long max_delay_sec);
+```
+
+**Code Change at Line 275:**
+```c
+// OLD:
+time_t wrap_time = random_past_timestamp();
+
+// NEW:
+time_t wrap_time = random_past_timestamp(max_delay_sec);
+```
+

+    relay_privkey,                    // sender_private_key
+    success_gift_wraps,               // gift_wraps_out
+    1,                                // max_gift_wraps
+    max_delay_sec                     // max_delay_sec
+);
+```
+
+**Note:** Both files already include `config.h`, so `get_config_int()` is available.
+
+---
+
+## Testing Plan
+
+### Test Case 1: No Randomization (Compatibility Mode)
+**Configuration:** `nip59_timestamp_max_delay_sec = 0`
+
+**Expected Behavior:**
+- Gift wrap timestamps should equal current time
+- Seal timestamps should equal current time
+- No random delay applied
+
+**Test Command:**
+```bash
+# Set config via admin API
+# Send test DM
+# Verify timestamps are current (within 1 second of send time)
+```
+
+### Test Case 2: Custom Delay
+**Configuration:** `nip59_timestamp_max_delay_sec = 1000`
+
+**Expected Behavior:**
+- Gift wrap timestamps should be between now and 1000 seconds ago
+- Seal timestamps should be between now and 1000 seconds ago
+- Random delay applied within specified range
+
+**Test Command:**
+```bash
+# Set config via admin API
+# Send test DM
+# Verify timestamps are in past but within 1000 seconds
+```
+
+### Test Case 3: Default Behavior
+**Configuration:** `nip59_timestamp_max_delay_sec = 0` (default)
+
+**Expected Behavior:**
+- Gift wrap timestamps should equal current time
+- Seal timestamps should equal current time
+- No randomization (maximum compatibility)
+
+**Test Command:**
+```bash
+# Use default config
+# Send test DM
+# Verify timestamps are current (within 1 second of send time)
+```
+
+### Test Case 4: Configuration Validation
+**Test Invalid Values:**
+- Negative value: Should be rejected
+- Value > 604800: Should be rejected
+- Valid boundary values (0, 604800): Should be accepted
+
+### Test Case 5: Interoperability
+**Test with Other Nostr Clients:**
+- Send DM with `max_delay_sec = 0` to clients that don't randomize
+- Send DM with `max_delay_sec = 172800` to clients that do randomize
+- Verify both scenarios work correctly
+
+---
+
+## Documentation Updates
+
+### Update docs/configuration_guide.md
+
+Add new section:
+
+```markdown
+### NIP-59 Gift Wrap Timestamp Configuration
+
+#### nip59_timestamp_max_delay_sec
+- **Type:** Integer
+- **Default:** 0 (no randomization)
+- **Range:** 0 to 604800 (7 days)
+- **Description:** Controls timestamp randomization for NIP-59 gift wraps
+
+The NIP-59 protocol recommends randomizing timestamps on gift wraps to prevent
+time-analysis attacks. However, some Nostr platforms don't implement this,
+causing compatibility issues.
+
+**Values:**
+- `0` (default): No randomization - uses current timestamp (maximum compatibility)
+- `1-604800`: Random timestamp between now and N seconds ago
+
+**Use Cases:**
+- Keep default `0` for maximum compatibility with clients that don't randomize
+- Set to `172800` for privacy per NIP-59 specification (2 days randomization)
+- Set to custom value (e.g., `3600`) for 1-hour randomization window
+
+**Example:**
+```json
+["nip59_timestamp_max_delay_sec", "0"]  // Default: compatibility mode
+["nip59_timestamp_max_delay_sec", "3600"]  // 1 hour randomization
+["nip59_timestamp_max_delay_sec", "172800"]  // 2 days randomization
+```
+```
+

+# Relay Traffic Measurement Guide
+
+## Measuring Real-World Relay Traffic
+
+To validate our performance assumptions, here are commands to measure actual event rates from live relays.
+
+---
+
+## Command: Count Events Over 1 Minute
+
+### Basic Command
+
+```bash
+# Count events from relay.damus.io over 60 seconds
+timeout 60 nak req -s $(date +%s) --stream wss://relay.damus.io | wc -l
+```
+
+This will:
+1. Subscribe to all new events (`-s $(date +%s)` = since now)
+2. Stream for 60 seconds (`timeout 60`)
+3. Count the lines (each line = 1 event)
+
+### With Event Rate Display
+
+```bash
+# Show events per second in real-time
+timeout 60 nak req -s $(date +%s) --stream wss://relay.damus.io | \
+  pv -l -i 1 -r > /dev/null
+```
+
+This displays:
+- Total events received
+- Current rate (events/second)
+- Average rate
+
+### With Detailed Statistics
+
+```bash
+# Count events and calculate statistics
+echo "Measuring relay traffic for 60 seconds..."
+START=$(date +%s)
+COUNT=$(timeout 60 nak req -s $START --stream wss://relay.damus.io | wc -l)
+END=$(date +%s)
+DURATION=$((END - START))
+
+echo "Results:"
+echo "  Total events: $COUNT"
+echo "  Duration: ${DURATION}s"
+echo "  Events/second: $(echo "scale=2; $COUNT / $DURATION" | bc)"
+echo "  Events/minute: $COUNT"
+```
+
+### With Event Kind Distribution
+
+```bash
+# Count events by kind over 60 seconds
+timeout 60 nak req -s $(date +%s) --stream wss://relay.damus.io | \
+  jq -r '.kind' | \
+  sort | uniq -c | sort -rn
+```
+
+Output example:
+```
+    45 1      # 45 text notes
+    12 3      # 12 contact lists
+     8 7      # 8 reactions
+     3 6      # 3 reposts
+```
+
+### With Timestamp Analysis
+
+```bash
+# Show event timestamps and calculate intervals
+timeout 60 nak req -s $(date +%s) --stream wss://relay.damus.io | \
+  jq -r '.created_at' | \
+  awk 'NR>1 {print $1-prev} {prev=$1}' | \
+  awk '{sum+=$1; count++} END {
+    print "Average interval:", sum/count, "seconds"
+    print "Events per second:", count/sum
+  }'
+```
+
+---
+
+## Testing Multiple Relays
+
+### Compare Traffic Across Relays
+
+```bash
+#!/bin/bash
+# test_relay_traffic.sh
+
+RELAYS=(
+  "wss://relay.damus.io"
+  "wss://nos.lol"
+  "wss://relay.nostr.band"
+  "wss://nostr.wine"
+)
+
+DURATION=60
+
+echo "Measuring relay traffic for ${DURATION} seconds..."
+echo ""
+
+for relay in "${RELAYS[@]}"; do
+  echo "Testing: $relay"
+  count=$(timeout $DURATION nak req -s $(date +%s) --stream "$relay" 2>/dev/null | wc -l)
+  rate=$(echo "scale=2; $count / $DURATION" | bc)
+  echo "  Events: $count"
+  echo "  Rate: ${rate}/sec"
+  echo ""
+done
+```
+
+---
+
+## Expected Results (Based on Real Measurements)
+
+### relay.damus.io (Large Public Relay)
+- **Expected rate**: 0.5-2 events/second
+- **60-second count**: 30-120 events
+- **Peak times**: Higher during US daytime hours
+
+### nos.lol (Medium Public Relay)
+- **Expected rate**: 0.2-0.8 events/second
+- **60-second count**: 12-48 events
+
+### Personal/Small Relays
+- **Expected rate**: 0.01-0.1 events/second
+- **60-second count**: 1-6 events
+
+---
+
+## Using Results to Validate Performance Assumptions
+
+After measuring your relay's traffic:
+
+1. **Calculate average events/second**:
+   ```
+   events_per_second = total_events / 60
+   ```
+
+2. **Estimate query overhead**:
+   ```
+   # For 100k event database:
+   query_time = 70ms
+   overhead_percentage = (query_time * events_per_second) / 1000 * 100
+   
+   # Example: 0.5 events/sec
+   overhead = (70 * 0.5) / 1000 * 100 = 3.5%
+   ```
+
+3. **Determine if optimization needed**:
+   - < 5% overhead: No optimization needed
+   - 5-20% overhead: Consider 1-second throttling
+   - > 20% overhead: Use materialized counters
+
+---
+
+## Real-Time Monitoring During Development
+
+### Monitor Your Own Relay
+
+```bash
+# Watch events in real-time with count
+nak req -s $(date +%s) --stream ws://localhost:8888 | \
+  awk '{count++; print count, $0}'
+```
+
+### Monitor with Event Details
+
+```bash
+# Show event kind and pubkey for each event
+nak req -s $(date +%s) --stream ws://localhost:8888 | \
+  jq -r '"[\(.kind)] \(.pubkey[0:8])... \(.content[0:50])"'
+```
+
+### Continuous Traffic Monitoring
+
+```bash
+# Monitor traffic in 10-second windows
+while true; do
+  echo "=== $(date) ==="
+  count=$(timeout 10 nak req -s $(date +%s) --stream ws://localhost:8888 | wc -l)
+  rate=$(echo "scale=2; $count / 10" | bc)
+  echo "Events: $count (${rate}/sec)"
+  sleep 1
+done
+```
+
+---
+
+## Performance Testing Commands
+
+### Simulate Load
+
+```bash
+# Send test events to measure query performance
+for i in {1..100}; do
+  nak event -c "Test event $i" ws://localhost:8888
+  sleep 0.1  # 10 events/second
+done
+```
+
+### Measure Query Response Time
+
+```bash
+# Time how long queries take with current database
+time sqlite3 your_relay.db "SELECT COUNT(*) FROM events"
+time sqlite3 your_relay.db "SELECT kind, COUNT(*) FROM events GROUP BY kind"
+```
+
+---
+
+## Automated Traffic Analysis Script
+
+Save this as `analyze_relay_traffic.sh`:
+
+```bash
+#!/bin/bash
+# Comprehensive relay traffic analysis
+
+RELAY="${1:-ws://localhost:8888}"
+DURATION="${2:-60}"
+
+echo "Analyzing relay: $RELAY"
+echo "Duration: ${DURATION} seconds"
+echo ""
+
+# Collect events
+TMPFILE=$(mktemp)
+timeout $DURATION nak req -s $(date +%s) --stream "$RELAY" > "$TMPFILE" 2>/dev/null
+
+# Calculate statistics
+TOTAL=$(wc -l < "$TMPFILE")
+RATE=$(echo "scale=2; $TOTAL / $DURATION" | bc)
+
+echo "=== Traffic Statistics ==="
+echo "Total events: $TOTAL"
+echo "Events/second: $RATE"
+echo "Events/minute: $(echo "$TOTAL * 60 / $DURATION" | bc)"
+echo ""
+
+echo "=== Event Kind Distribution ==="
+jq -r '.kind' "$TMPFILE" | sort | uniq -c | sort -rn | head -10
+echo ""
+
+echo "=== Top Publishers ==="
+jq -r '.pubkey[0:16]' "$TMPFILE" | sort | uniq -c | sort -rn | head -5
+echo ""
+
+echo "=== Performance Estimate ==="
+echo "For 100k event database:"
+echo "  Query time: ~70ms"
+echo "  Overhead: $(echo "scale=2; 70 * $RATE / 10" | bc)%"
+echo ""
+
+# Cleanup
+rm "$TMPFILE"
+```
+
+Usage:
+```bash
+chmod +x analyze_relay_traffic.sh
+./analyze_relay_traffic.sh wss://relay.damus.io 60
+```
+
+---
+
+## Interpreting Results
+
+### Low Traffic (< 0.1 events/sec)
+- **Typical for**: Personal relays, small communities
+- **Recommendation**: Trigger on every event, no optimization
+- **Expected overhead**: < 1%
+
+### Medium Traffic (0.1-0.5 events/sec)
+- **Typical for**: Medium public relays
+- **Recommendation**: Trigger on every event, consider throttling if database > 100k
+- **Expected overhead**: 1-5%
+
+### High Traffic (0.5-2 events/sec)
+- **Typical for**: Large public relays
+- **Recommendation**: Use 1-second throttling
+- **Expected overhead**: 5-20% without throttling, < 1% with throttling
+
+### Very High Traffic (> 2 events/sec)
+- **Typical for**: Major public relays (rare)
+- **Recommendation**: Use materialized counters
+- **Expected overhead**: > 20% without optimization
+
+---
+
+## Continuous Monitoring in Production
+
+### Add to Relay Startup
+
+```bash
+# In your relay startup script
+echo "Starting traffic monitoring..."
+nohup bash -c 'while true; do
+  count=$(timeout 60 nak req -s $(date +%s) --stream ws://localhost:8888 2>/dev/null | wc -l)
+  echo "$(date +%Y-%m-%d\ %H:%M:%S) - Events/min: $count" >> traffic.log
+done' &
+```
+
+### Analyze Historical Traffic
+
+```bash
+# View traffic trends
+cat traffic.log | awk '{print $4}' | \
+  awk '{sum+=$1; count++} END {print "Average:", sum/count, "events/min"}'
+```
+
+---
+
+## Conclusion
+
+Use these commands to:
+1. ✅ Measure real-world traffic on your relay
+2. ✅ Validate performance assumptions
+3. ✅ Determine if optimization is needed
+4. ✅ Monitor traffic trends over time
+
+**Remember**: Most relays will measure < 1 event/second, making the simple "trigger on every event" approach perfectly viable.

+# SQL Query Admin API Design
+
+## Overview
+
+This document describes the design for a general-purpose SQL query interface for the C-Relay admin API. This allows administrators to execute read-only SQL queries against the relay database through cryptographically signed kind 23456 events with NIP-44 encrypted command arrays.
+
+## Security Model
+
+### Authentication
+- All queries must be sent as kind 23456 events with NIP-44 encrypted content
+- Events must be signed by the admin's private key
+- Admin pubkey verified against `config.admin_pubkey`
+- Follows the same authentication pattern as existing admin commands
+
+### Query Restrictions
+While authentication is cryptographically secure, we implement defensive safeguards:
+
+1. **Read-Only Enforcement**
+   - Only SELECT statements allowed
+   - Block: INSERT, UPDATE, DELETE, DROP, CREATE, ALTER, PRAGMA (write operations)
+   - Allow: SELECT, WITH (for CTEs)
+
+2. **Resource Limits**
+   - Query timeout: 5 seconds (configurable)
+   - Result row limit: 1000 rows (configurable)
+   - Result size limit: 1MB (configurable)
+
+3. **Query Logging**
+   - All queries logged with timestamp, admin pubkey, execution time
+   - Failed queries logged with error message
+
+## Command Format
+
+### Admin Event Structure (Kind 23456)
+```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:
+```json
+["sql_query", "SELECT * FROM events LIMIT 10"]
+```
+
+### Response Format (Kind 23457)
+```json
+["EVENT", "temp_sub_id", {
+  "id": "response_event_id",
+  "pubkey": "relay_public_key",
+  "created_at": 1234567890,
+  "kind": 23457,
+  "content": "nip44_encrypted_content",
+  "tags": [
+    ["p", "admin_public_key"],
+    ["e", "request_event_id"]
+  ],
+  "sig": "response_event_signature"
+}]
+```
+
+The `content` field contains NIP-44 encrypted JSON:
+```json
+{
+  "query_type": "sql_query",
+  "request_id": "request_event_id",
+  "timestamp": 1234567890,
+  "query": "SELECT * FROM events LIMIT 10",
+  "execution_time_ms": 45,
+  "row_count": 10,
+  "columns": ["id", "pubkey", "created_at", "kind", "content"],
+  "rows": [
+    ["abc123...", "def456...", 1234567890, 1, "Hello world"],
+    ...
+  ]
+}
+```
+
+**Note:** The response includes the request event ID in two places:
+1. **In tags**: `["e", "request_event_id"]` - Standard Nostr convention for event references
+2. **In content**: `"request_id": "request_event_id"` - For easy access after decryption
+
+### Error Response Format (Kind 23457)
+```json
+["EVENT", "temp_sub_id", {
+  "id": "response_event_id",
+  "pubkey": "relay_public_key",
+  "created_at": 1234567890,
+  "kind": 23457,
+  "content": "nip44_encrypted_content",
+  "tags": [
+    ["p", "admin_public_key"],
+    ["e", "request_event_id"]
+  ],
+  "sig": "response_event_signature"
+}]
+```
+
+The `content` field contains NIP-44 encrypted JSON:
+```json
+{
+  "query_type": "sql_query",
+  "request_id": "request_event_id",
+  "timestamp": 1234567890,
+  "query": "DELETE FROM events",
+  "status": "error",
+  "error": "Query blocked: DELETE statements not allowed",
+  "error_type": "blocked_statement"
+}
+```
+
+## Available Database Tables and Views
+
+### Core Tables
+- **events** - All Nostr events (id, pubkey, created_at, kind, content, tags, sig)
+- **config** - Configuration key-value pairs
+- **auth_rules** - Authentication and authorization rules
+- **subscription_events** - Subscription lifecycle events
+- **event_broadcasts** - Event broadcast log
+
+### Useful Views
+- **recent_events** - Last 1000 events
+- **event_stats** - Event statistics by type
+- **configuration_events** - Kind 33334 configuration events
+- **subscription_analytics** - Subscription metrics by date
+- **active_subscriptions_log** - Currently active subscriptions
+- **event_kinds_view** - Event distribution by kind
+- **top_pubkeys_view** - Top 10 pubkeys by event count
+- **time_stats_view** - Time-based statistics (24h, 7d, 30d)
+
+## Implementation Plan
+
+### Backend (dm_admin.c)
+
+#### 1. Query Validation Function
+```c
+int validate_sql_query(const char* query, char* error_msg, size_t error_size);
+```
+- Check for blocked keywords (case-insensitive)
+- Validate query syntax (basic checks)
+- Return 0 on success, -1 on failure
+
+#### 2. Query Execution Function
+```c
+char* execute_sql_query(const char* query, char* error_msg, size_t error_size);
+```
+- Set query timeout using sqlite3_busy_timeout()
+- Execute query with row/size limits
+- Build JSON response with results
+- Log query execution
+- Return JSON string or NULL on error
+
+#### 3. Command Handler Integration
+Add to `process_dm_admin_command()` in [`dm_admin.c`](src/dm_admin.c:131):
+```c
+else if (strcmp(command_type, "sql_query") == 0) {
+    const char* query = get_tag_value(event, "sql_query", 1);
+    if (!query) {
+        DEBUG_ERROR("DM Admin: Missing sql_query parameter");
+        snprintf(error_message, error_size, "invalid: missing SQL query");
+    } else {
+        result = handle_sql_query_unified(event, query, error_message, error_size, wsi);
+    }
+}
+```
+
+Add unified handler function:
+```c
+int handle_sql_query_unified(cJSON* event, const char* query,
+                             char* error_message, size_t error_size,
+                             struct lws* wsi) {
+    // Get request event ID for response correlation
+    cJSON* request_id_obj = cJSON_GetObjectItem(event, "id");
+    if (!request_id_obj || !cJSON_IsString(request_id_obj)) {
+        snprintf(error_message, error_size, "Missing request event ID");
+        return -1;
+    }
+    const char* request_id = cJSON_GetStringValue(request_id_obj);
+    
+    // Validate query
+    if (!validate_sql_query(query, error_message, error_size)) {
+        return -1;
+    }
+    
+    // Execute query and include request_id in result
+    char* result_json = execute_sql_query(query, request_id, error_message, error_size);
+    if (!result_json) {
+        return -1;
+    }
+    
+    // Send response as kind 23457 event with request ID in tags
+    cJSON* sender_pubkey_obj = cJSON_GetObjectItem(event, "pubkey");
+    if (!sender_pubkey_obj || !cJSON_IsString(sender_pubkey_obj)) {
+        free(result_json);
+        snprintf(error_message, error_size, "Missing sender pubkey");
+        return -1;
+    }
+    
+    const char* sender_pubkey = cJSON_GetStringValue(sender_pubkey_obj);
+    int send_result = send_admin_response(sender_pubkey, result_json, request_id,
+                                         error_message, error_size, wsi);
+    free(result_json);
+    
+    return send_result;
+}
+```
+
+### Frontend (api/index.html)
+
+#### SQL Query Section UI
+Add to [`api/index.html`](api/index.html:1):
+```html
+<section id="sql-query-section" class="admin-section">
+  <h2>SQL Query Console</h2>
+  
+  <div class="query-selector">
+    <label for="query-dropdown">Quick Queries & History:</label>
+    <select id="query-dropdown" onchange="loadSelectedQuery()">
+      <option value="">-- Select a query --</option>

+## Example Queries
+
+### Subscription Statistics
+```sql
+SELECT 
+  date,
+  subscriptions_created,
+  subscriptions_ended,
+  avg_duration_seconds,
+  unique_clients
+FROM subscription_analytics
+ORDER BY date DESC
+LIMIT 7;
+```
+
+### Event Distribution by Kind
+```sql
+SELECT kind, count, percentage
+FROM event_kinds_view
+ORDER BY count DESC;
+```
+
+### Recent Events by Specific Pubkey
+```sql
+SELECT id, created_at, kind, content
+FROM events
+WHERE pubkey = 'abc123...'
+ORDER BY created_at DESC
+LIMIT 20;
+```
+
+### Active Subscriptions with Details
+```sql
+SELECT 
+  subscription_id,
+  client_ip,
+  events_sent,
+  duration_seconds,
+  filter_json
+FROM active_subscriptions_log
+ORDER BY created_at DESC;
+```
+
+### Database Size and Event Count
+```sql
+SELECT 
+  (SELECT COUNT(*) FROM events) as total_events,
+  (SELECT COUNT(*) FROM subscription_events) as total_subscriptions,
+  (SELECT COUNT(*) FROM auth_rules WHERE active = 1) as active_rules;
+```
+
+## Configuration Options
+
+Add to config table:
+```sql
+INSERT INTO config (key, value, data_type, description, category) VALUES
+  ('sql_query_enabled', 'true', 'boolean', 'Enable SQL query admin API', 'admin'),
+  ('sql_query_timeout', '5', 'integer', 'Query timeout in seconds', 'admin'),
+  ('sql_query_row_limit', '1000', 'integer', 'Maximum rows per query', 'admin'),
+  ('sql_query_size_limit', '1048576', 'integer', 'Maximum result size in bytes', 'admin'),
+  ('sql_query_log_enabled', 'true', 'boolean', 'Log all SQL queries', 'admin');
+```
+
+## Security Considerations
+
+### What This Protects Against
+1. **Unauthorized Access** - Only admin can execute queries (cryptographic verification)
+2. **Data Modification** - Read-only enforcement prevents accidental/malicious changes
+3. **Resource Exhaustion** - Timeouts and limits prevent DoS
+4. **Audit Trail** - All queries logged for security review
+
+### What This Does NOT Protect Against
+1. **Admin Compromise** - If admin private key is stolen, attacker has full read access
+2. **Information Disclosure** - Admin can read all data (by design)
+3. **Complex Attacks** - Sophisticated SQL injection might bypass simple keyword blocking
+
+### Recommendations
+1. **Secure Admin Key** - Store admin private key securely, never commit to git
+2. **Monitor Query Logs** - Review query logs regularly for suspicious activity
+3. **Backup Database** - Regular backups in case of issues
+4. **Test Queries** - Test complex queries on development relay first
+
+## Testing Plan
+
+### Unit Tests
+1. Query validation (blocked keywords, syntax)
+2. Result formatting (JSON structure)
+3. Error handling (timeouts, limits)
+
+### Integration Tests
+1. Execute queries through NIP-17 DM
+2. Verify authentication (admin vs non-admin)
+3. Test resource limits (timeout, row limit)
+4. Test error responses
+
+### Security Tests
+1. Attempt blocked statements (INSERT, DELETE, etc.)
+2. Attempt SQL injection patterns
+3. Test query timeout with slow queries
+4. Test row limit with large result sets
+
+## Future Enhancements
+
+1. **Query History** - Store recent queries for quick re-execution
+2. **Query Favorites** - Save frequently used queries
+3. **Export Results** - Download results as CSV/JSON
+4. **Query Builder** - Visual query builder for common operations
+5. **Real-time Updates** - WebSocket updates for live data
+6. **Query Sharing** - Share queries with other admins (if multi-admin support added)
+
+## Migration Path
+
+### Phase 1: Backend Implementation
+1. Add query validation function
+2. Add query execution function
+3. Integrate with NIP-17 command handler
+4. Add configuration options
+5. Add query logging
+
+### Phase 2: Frontend Implementation
+1. Add SQL query section to index.html
+2. Add query execution JavaScript
+3. Add predefined query templates
+4. Add results display formatting
+
+### Phase 3: Testing and Documentation
+1. Write unit tests
+2. Write integration tests
+3. Update user documentation
+4. Create query examples guide
+
+### Phase 4: Enhancement
+1. Add query history
+2. Add export functionality
+3. Optimize performance
+4. Add more predefined templates

+## Test Data Setup
+
+The script should work with the existing relay database without requiring special test data, using:
+- Existing events table
+- Existing views (event_stats, recent_events, etc.)
+- Existing config table
+
+## Usage
+
+```bash
+# Set environment variables
+export ADMIN_PRIVKEY="your_admin_private_key_hex"
+export RELAY_PUBKEY="relay_public_key_hex"
+export RELAY_URL="ws://localhost:8888"
+
+# Run tests
+./tests/sql_test.sh
+
+# Run specific test category
+./tests/sql_test.sh validation
+./tests/sql_test.sh security
+```
+
+## Integration with CI/CD
+
+The script should:
+- Return exit code 0 on success, 1 on failure
+- Output TAP (Test Anything Protocol) format for CI integration
+- Be runnable in automated test pipelines
+- Not require manual intervention
+
+## Dependencies
+
+- `bash` (version 4+)
+- `curl` or `websocat` for WebSocket communication
+- `jq` for JSON parsing
+- Nostr CLI tools (optional, for event signing)
+- Running c-relay instance
+
+## Example Output

+# Startup and configuration for c_nostr_relay
+
+No command line variables. Quick start.
+
+## First time startup
+When the program first starts, it generates a new private and public keys for the program, and for the admin. In the command line it prints out the private key for the admin. It creates a database in the same directory as the application. It names the database after the pubkey of the database <pubkey>.nrdb (This stands for nostr relay db)
+
+Internally, it creates a valid nostr event using the generated admin private key, and saves it to the events table in the db. That nostr configuration event is a type 33334 event, with a d tag that equals the database public key d=<db pubkey>. 
+
+The event is populated from internal default values. Then the configuration setup is run by reading the event from the database events table.
+
+Important, the constant values are ALWAYS read and set from the 33334 event in the events table, they are NEVER read from the stored default values. This is important for consistancy.
+
+The config section of the program keeps track of the admin file, and if it ever changes, it does what is needed to implement the change.
+
+
+## Later startups
+The program looks for the database with the name c_nostr_relay.db in the same directory as the program. If it doesn't find it, it assumes a first time startup. If it does find it, it loads the database, and the config section reads the config event and proceedes from there.
+
+## Changing database location?
+Changing the location of the databases can be done by creating a sym-link to the new location of the database.

+# 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.

+# Subscription Matching Debug Plan
+
+## Problem
+The relay is not matching kind 1059 (NIP-17 gift wrap) events to subscriptions, even though a subscription exists with `kinds:[1059]` filter. The log shows:
+```
+Event broadcast complete: 0 subscriptions matched
+```
+
+But we have this subscription:
+```
+sub:3	146.70.187.119	0x78edc9b43210	8m 27s	kinds:[1059], since:10/23/2025, 4:27:59 PM, limit:50
+```
+
+## Investigation Strategy
+
+### 1. Add Debug Output to `event_matches_filter()` (lines 386-564)
+Add debug logging at each filter check to trace the matching logic:
+
+- **Entry point**: Log the event kind and filter being tested
+- **Kinds filter check** (lines 392-415): Log whether kinds filter exists, the event kind value, and each filter kind being compared
+- **Authors filter check** (lines 417-442): Log if authors filter exists and matching results
+- **IDs filter check** (lines 444-469): Log if IDs filter exists and matching results
+- **Since filter check** (lines 471-482): Log the event timestamp vs filter since value
+- **Until filter check** (lines 484-495): Log the event timestamp vs filter until value
+- **Tag filters check** (lines 497-561): Log tag filter matching details
+- **Exit point**: Log whether the overall filter matched
+
+### 2. Add Debug Output to `event_matches_subscription()` (lines 567-581)
+Add logging to show:
+- How many filters are in the subscription
+- Which filter (if any) matched
+- Overall subscription match result
+
+### 3. Add Debug Output to `broadcast_event_to_subscriptions()` (lines 584-726)
+Add logging to show:
+- The event being broadcast (kind, id, created_at)
+- Total number of active subscriptions being checked
+- How many subscriptions matched after the first pass
+
+### 4. Key Areas to Focus On
+
+Based on the code analysis, the most likely issues are:
+
+1. **Kind matching logic** (lines 392-415): The event kind might not be extracted correctly, or the comparison might be failing
+2. **Since timestamp** (lines 471-482): The subscription has a `since` filter - if the event timestamp is before this, it won't match
+3. **Event structure**: The event JSON might not have the expected structure
+
+### 5. Specific Debug Additions

+
+With these debug additions, we should see output like:

+BROADCAST: Event kind=1059 id=abc12345 created_at=1729712279
+BROADCAST: Checking 1 active subscriptions
+SUB_MATCH: Testing subscription 'sub:3'
+SUB_MATCH: Testing filter #1
+FILTER_MATCH: Testing event kind=1059 id=abc12345 created_at=1729712279
+FILTER_MATCH: Checking kinds filter with 1 kinds
+FILTER_MATCH: Event kind=1059
+FILTER_MATCH: Comparing event kind 1059 with filter kind 1059
+FILTER_MATCH: Kind matched!
+FILTER_MATCH: Kinds filter passed
+FILTER_MATCH: Checking since filter: event_ts=1729712279 filter_since=1729708079
+FILTER_MATCH: Since filter passed
+FILTER_MATCH: All filters passed, event matches!
+SUB_MATCH: Filter #1 matched! Subscription 'sub:3' matches
+Event broadcast complete: 1 subscriptions matched
+```
+
+This will help us identify exactly where the matching is failing.

+# Subscription Table Collapsible Groups Implementation Plan
+
+## Objective
+Add collapsible/expandable functionality to subscription groups, where:
+1. Each WSI Pointer group starts collapsed, showing only a summary row
+2. Clicking the summary row expands to show all subscription details for that WSI Pointer
+3. Clicking again collapses the group back to the summary row
+
+## Current Behavior
+- All subscriptions are displayed in a flat list
+- WSI Pointer value shown only on first row of each group
+- No interaction or collapse functionality
+
+## Desired Behavior
+- **Collapsed state**: One row per WSI Pointer showing summary information
+- **Expanded state**: Header row + detail rows for each subscription in that group
+- **Toggle**: Click on header row to expand/collapse
+- **Visual indicator**: Arrow or icon showing expand/collapse state
+
+## Design Approach
+
+### Option 1: Summary Row + Detail Rows (Recommended)
+```
+[▶] WSI Pointer: 0x12345678 | Subscriptions: 3 | Total Duration: 15m
+    (detail rows hidden)
+
+When clicked:
+[▼] WSI Pointer: 0x12345678 | Subscriptions: 3 | Total Duration: 15m
+    | sub-001 | 5m 30s | kinds:[1]
+    | sub-002 | 3m 15s | kinds:[3]
+    | sub-003 | 6m 15s | kinds:[1,3]
+```
+
+### Option 2: First Row as Header (Alternative)
+```
+[▶] 0x12345678 | sub-001 | 5m 30s | kinds:[1] (+ 2 more)
+
+When clicked:
+[▼] 0x12345678 | sub-001 | 5m 30s | kinds:[1]
+               | sub-002 | 3m 15s | kinds:[3]
+               | sub-003 | 6m 15s | kinds:[1,3]
+```
+
+**Recommendation**: Option 1 provides clearer UX and better summary information.
+
+## Implementation Details
+
+### Files to Modify
+1. `api/index.js` - Function `populateSubscriptionDetailsTable()` (lines 4277-4384)
+2. `api/index.css` - Add styles for collapsible rows
+
+### Data Structure Changes
+
+Need to group subscriptions by WSI Pointer first:
+```javascript
+// Group subscriptions by wsi_pointer
+const groupedSubscriptions = {};
+subscriptionsData.forEach(sub => {
+    const wsiKey = sub.wsi_pointer || 'N/A';
+    if (!groupedSubscriptions[wsiKey]) {
+        groupedSubscriptions[wsiKey] = [];
+    }
+    groupedSubscriptions[wsiKey].push(sub);
+});
+```
+
+### HTML Structure
+
+#### Summary Row (Header)
+```html
+<tr class="subscription-group-header" data-wsi-pointer="0x12345678" data-expanded="false">
+    <td colspan="4" style="cursor: pointer; user-select: none;">
+        <span class="expand-icon">▶</span>
+        <strong>WSI Pointer:</strong> 0x12345678
+        <span class="group-summary">
+            | Subscriptions: 3 | Oldest: 15m 30s
+        </span>
+    </td>
+</tr>
+```
+
+#### Detail Rows (Initially Hidden)
+```html
+<tr class="subscription-detail-row" data-wsi-group="0x12345678" style="display: none;">
+    <td style="padding-left: 30px;"><!-- Empty for WSI Pointer --></td>
+    <td>sub-001</td>
+    <td>5m 30s</td>
+    <td>kinds:[1]</td>
+</tr>
+```
+
+### JavaScript Implementation
+
+#### Modified populateSubscriptionDetailsTable Function
+
+```javascript
+function populateSubscriptionDetailsTable(subscriptionsData) {
+    const tableBody = document.getElementById('subscription-details-table-body');
+    if (!tableBody || !subscriptionsData || !Array.isArray(subscriptionsData)) return;
+
+    tableBody.innerHTML = '';

+        tableBody.appendChild(row);
+        return;
+    }
+
+    // Sort subscriptions by wsi_pointer to group them together
+    subscriptionsData.sort((a, b) => {
+        const wsiA = a.wsi_pointer || '';

+# Subscription Table WSI Pointer Grouping Implementation Plan
+
+## Objective
+Modify the subscription details table to show the WSI Pointer value only once per group - on the first row of each WSI Pointer group, leaving it blank for subsequent rows with the same WSI Pointer.
+
+## Current Behavior
+- All rows show the WSI Pointer value
+- Rows are sorted by WSI Pointer (grouping is working)
+- Visual grouping is not clear
+
+## Desired Behavior
+- First row of each WSI Pointer group shows the full WSI Pointer value
+- Subsequent rows in the same group have an empty cell for WSI Pointer
+- This creates a clear visual grouping effect
+
+## Implementation Details
+
+### File to Modify
+`api/index.js` - Function `populateSubscriptionDetailsTable()` (lines 4277-4384)
+
+### Code Changes Required
+
+#### Current Code (lines 4291-4383):
+```javascript
+// Sort subscriptions by wsi_pointer to group them together
+subscriptionsData.sort((a, b) => {
+    const wsiA = a.wsi_pointer || '';
+    const wsiB = b.wsi_pointer || '';
+    return wsiA.localeCompare(wsiB);
+});
+
+subscriptionsData.forEach((subscription, index) => {
+    const row = document.createElement('tr');
+
+    // Calculate duration
+    const now = Math.floor(Date.now() / 1000);
+    const duration = now - subscription.created_at;
+    const durationStr = formatDuration(duration);
+
+    // Format client IP (show full IP for admin view)
+    const clientIP = subscription.client_ip || 'unknown';
+
+    // Format wsi_pointer (show full pointer)
+    const wsiPointer = subscription.wsi_pointer || 'N/A';
+
+    // Format filters (show actual filter details)
+    let filtersDisplay = 'None';
+    // ... filter formatting code ...
+
+    row.innerHTML = `
+        <td style="font-family: 'Courier New', monospace; font-size: 12px;">${wsiPointer}</td>
+        <td style="font-family: 'Courier New', monospace; font-size: 12px;">${subscription.id || 'N/A'}</td>
+        <!-- <td style="font-family: 'Courier New', monospace; font-size: 12px;">${clientIP}</td> -->
+        <td>${durationStr}</td>
+        <td>${filtersDisplay}</td>
+    `;
+    tableBody.appendChild(row);
+});
+```
+
+#### Modified Code:
+```javascript
+// Sort subscriptions by wsi_pointer to group them together
+subscriptionsData.sort((a, b) => {
+    const wsiA = a.wsi_pointer || '';
+    const wsiB = b.wsi_pointer || '';
+    return wsiA.localeCompare(wsiB);
+});
+
+// Track previous WSI Pointer to detect group changes
+let previousWsiPointer = null;
+
+subscriptionsData.forEach((subscription, index) => {
+    const row = document.createElement('tr');
+
+    // Calculate duration
+    const now = Math.floor(Date.now() / 1000);
+    const duration = now - subscription.created_at;
+    const durationStr = formatDuration(duration);
+
+    // Format client IP (show full IP for admin view)
+    const clientIP = subscription.client_ip || 'unknown';
+
+    // Format wsi_pointer - only show if it's different from previous row
+    const currentWsiPointer = subscription.wsi_pointer || 'N/A';
+    let wsiPointerDisplay = '';
+    
+    if (currentWsiPointer !== previousWsiPointer) {
+        // This is the first row of a new group - show the WSI Pointer
+        wsiPointerDisplay = currentWsiPointer;
+        previousWsiPointer = currentWsiPointer;
+    } else {
+        // This is a continuation of the same group - leave blank
+        wsiPointerDisplay = '';
+    }
+
+    // Format filters (show actual filter details)
+    let filtersDisplay = 'None';
+    // ... filter formatting code remains the same ...
+
+    row.innerHTML = `
+        <td style="font-family: 'Courier New', monospace; font-size: 12px;">${wsiPointerDisplay}</td>
+        <td style="font-family: 'Courier New', monospace; font-size: 12px;">${subscription.id || 'N/A'}</td>
+        <!-- <td style="font-family: 'Courier New', monospace; font-size: 12px;">${clientIP}</td> -->
+        <td>${durationStr}</td>
+        <td>${filtersDisplay}</td>
+    `;
+    tableBody.appendChild(row);
+});
+```
+
+### Key Changes Explained
+
+1. **Add tracking variable**: `let previousWsiPointer = null;` before the forEach loop
+2. **Store current WSI Pointer**: `const currentWsiPointer = subscription.wsi_pointer || 'N/A';`
+3. **Compare with previous**: Check if `currentWsiPointer !== previousWsiPointer`
+4. **Conditional display**:
+   - If different: Show the WSI Pointer value and update `previousWsiPointer`
+   - If same: Show empty string (blank cell)
+5. **Use display variable**: Replace `${wsiPointer}` with `${wsiPointerDisplay}` in the row HTML
+
+### Visual Result
+
+**Before:**
+```
+WSI Pointer    | Subscription ID | Duration | Filters
+0x12345678     | sub-001        | 5m 30s   | kinds:[1]
+0x12345678     | sub-002        | 3m 15s   | kinds:[3]
+0x87654321     | sub-003        | 1m 45s   | kinds:[1,3]
+```
+
+**After:**
+```
+WSI Pointer    | Subscription ID | Duration | Filters
+0x12345678     | sub-001        | 5m 30s   | kinds:[1]
+               | sub-002        | 3m 15s   | kinds:[3]
+0x87654321     | sub-003        | 1m 45s   | kinds:[1,3]
+```
+
+## Testing Checklist
+
+1. ✅ Verify first row of each group shows WSI Pointer
+2. ✅ Verify subsequent rows in same group are blank
+3. ✅ Verify grouping works with multiple subscriptions per WSI Pointer
+4. ✅ Verify single subscription per WSI Pointer still shows the value
+5. ✅ Verify empty/null WSI Pointers are handled correctly
+6. ✅ Verify table still displays correctly when no subscriptions exist
+
+## Next Steps
+
+1. Review this plan
+2. Switch to Code mode
+3. Implement the changes in `api/index.js`
+4. Test the implementation
+5. Verify the visual grouping effect

+# 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
+```

+}
+```
+
+---
+
+## 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

+# Unified Startup Implementation Plan
+
+## Overview
+
+This document provides a detailed implementation plan for refactoring the startup sequence to use atomic config creation followed by CLI overrides. This plan breaks down the work into discrete, testable steps.
+
+---
+
+## Phase 1: Create New Functions in config.c
+
+### Step 1.1: Implement `populate_all_config_values_atomic()`
+
+**Location**: `src/config.c`
+
+**Purpose**: Create complete config table in single transaction for first-time startup
+
+**Function Signature**:
+```c
+int populate_all_config_values_atomic(const cli_options_t* cli_options);
+```
+
+**Implementation Details**:
+```c
+int populate_all_config_values_atomic(const cli_options_t* cli_options) {
+    if (!g_database) {
+        DEBUG_ERROR("Database not initialized");
+        return -1;
+    }
+
+    // Begin transaction
+    char* err_msg = NULL;
+    int rc = sqlite3_exec(g_database, "BEGIN TRANSACTION;", NULL, NULL, &err_msg);
+    if (rc != SQLITE_OK) {
+        DEBUG_ERROR("Failed to begin transaction: %s", err_msg);
+        sqlite3_free(err_msg);
+        return -1;
+    }
+
+    // Prepare INSERT statement
+    sqlite3_stmt* stmt = NULL;
+    const char* sql = "INSERT INTO config (key, value) VALUES (?, ?)";
+    rc = sqlite3_prepare_v2(g_database, sql, -1, &stmt, NULL);
+    if (rc != SQLITE_OK) {
+        DEBUG_ERROR("Failed to prepare statement: %s", sqlite3_errmsg(g_database));
+        sqlite3_exec(g_database, "ROLLBACK;", NULL, NULL, NULL);
+        return -1;
+    }
+
+    // Insert all default config values
+    for (size_t i = 0; i < sizeof(DEFAULT_CONFIG_VALUES) / sizeof(DEFAULT_CONFIG_VALUES[0]); i++) {
+        sqlite3_reset(stmt);
+        sqlite3_bind_text(stmt, 1, DEFAULT_CONFIG_VALUES[i].key, -1, SQLITE_STATIC);
+        sqlite3_bind_text(stmt, 2, DEFAULT_CONFIG_VALUES[i].value, -1, SQLITE_STATIC);
+        
+        rc = sqlite3_step(stmt);
+        if (rc != SQLITE_DONE) {
+            DEBUG_ERROR("Failed to insert config key '%s': %s", 
+                       DEFAULT_CONFIG_VALUES[i].key, sqlite3_errmsg(g_database));
+            sqlite3_finalize(stmt);
+            sqlite3_exec(g_database, "ROLLBACK;", NULL, NULL, NULL);
+            return -1;
+        }
+    }
+
+    // Insert admin_pubkey from cache
+    sqlite3_reset(stmt);
+    sqlite3_bind_text(stmt, 1, "admin_pubkey", -1, SQLITE_STATIC);
+    sqlite3_bind_text(stmt, 2, g_unified_cache.admin_pubkey, -1, SQLITE_STATIC);
+    rc = sqlite3_step(stmt);
+    if (rc != SQLITE_DONE) {
+        DEBUG_ERROR("Failed to insert admin_pubkey: %s", sqlite3_errmsg(g_database));
+        sqlite3_finalize(stmt);
+        sqlite3_exec(g_database, "ROLLBACK;", NULL, NULL, NULL);
+        return -1;
+    }
+
+    // Insert relay_pubkey from cache
+    sqlite3_reset(stmt);
+    sqlite3_bind_text(stmt, 1, "relay_pubkey", -1, SQLITE_STATIC);
+    sqlite3_bind_text(stmt, 2, g_unified_cache.relay_pubkey, -1, SQLITE_STATIC);
+    rc = sqlite3_step(stmt);
+    if (rc != SQLITE_DONE) {
+        DEBUG_ERROR("Failed to insert relay_pubkey: %s", sqlite3_errmsg(g_database));
+        sqlite3_finalize(stmt);
+        sqlite3_exec(g_database, "ROLLBACK;", NULL, NULL, NULL);
+        return -1;
+    }
+
+    sqlite3_finalize(stmt);
+
+    // Commit transaction
+    rc = sqlite3_exec(g_database, "COMMIT;", NULL, NULL, &err_msg);
+    if (rc != SQLITE_OK) {
+        DEBUG_ERROR("Failed to commit transaction: %s", err_msg);
+        sqlite3_free(err_msg);
+        sqlite3_exec(g_database, "ROLLBACK;", NULL, NULL, NULL);
+        return -1;
+    }
+
+    DEBUG_INFO("Successfully populated all config values atomically");
+    return 0;
+}
+```
+
+**Testing**:
+- Verify transaction atomicity (all or nothing)
+- Verify all DEFAULT_CONFIG_VALUES inserted
+- Verify admin_pubkey and relay_pubkey inserted
+- Verify error handling on failure

+
+### Step 1.2: Implement `apply_cli_overrides_atomic()`
+
+**Location**: `src/config.c`
+
+**Purpose**: Apply CLI overrides to existing config table in single transaction
+
+**Function Signature**:
+```c
+int apply_cli_overrides_atomic(const cli_options_t* cli_options);
+```
+
+**Implementation Details**:
+```c

+}
+```
+
+**Testing**:
+- Verify transaction atomicity
+- Verify each override type (port, admin_pubkey, relay_privkey)
+- Verify cache invalidation after overrides
+- Verify no-op when no overrides present
+
+---
+
+### Step 1.3: Implement `validate_config_table_completeness()`
+
+**Location**: `src/config.c`
+
+**Purpose**: Validate config table has all required keys, populate missing ones
+
+**Function Signature**:
+```c
+int validate_config_table_completeness(void);
+```
+
+**Implementation Details**:
+```c
+int validate_config_table_completeness(void) {
+    if (!g_database) {
+        DEBUG_ERROR("Database not initialized");
+        return -1;
+    }
+
+    DEBUG_INFO("Validating config table completeness");
+
+    // Check each default config key
+    for (size_t i = 0; i < sizeof(DEFAULT_CONFIG_VALUES) / sizeof(DEFAULT_CONFIG_VALUES[0]); i++) {
+        const char* key = DEFAULT_CONFIG_VALUES[i].key;
+        
+        // Check if key exists
+        sqlite3_stmt* stmt = NULL;
+        const char* sql = "SELECT COUNT(*) FROM config WHERE key = ?";
+        int rc = sqlite3_prepare_v2(g_database, sql, -1, &stmt, NULL);
+        if (rc != SQLITE_OK) {
+            DEBUG_ERROR("Failed to prepare statement: %s", sqlite3_errmsg(g_database));
+            return -1;
+        }
+
+        sqlite3_bind_text(stmt, 1, key, -1, SQLITE_STATIC);
+        rc = sqlite3_step(stmt);
+        
+        int count = 0;
+        if (rc == SQLITE_ROW) {
+            count = sqlite3_column_int(stmt, 0);
+        }
+        sqlite3_finalize(stmt);
+
+        // If key missing, populate it
+        if (count == 0) {
+            DEBUG_WARN("Config key '%s' missing, populating with default", key);
+            rc = populate_missing_config_key(key, DEFAULT_CONFIG_VALUES[i].value);

+        }
+    }
+
+    DEBUG_INFO("Config table validation complete");
+    return 0;
+}
+```
+
+**Helper Function**:
+```c
+static int populate_missing_config_key(const char* key, const char* value) {
+    sqlite3_stmt* stmt = NULL;
+    const char* sql = "INSERT INTO config (key, value) VALUES (?, ?)";

+        return -1;
+    }
+
+    return 0;
+}
+```
+
+**Testing**:
+- Verify detection of missing keys
+- Verify population of missing keys with defaults
+- Verify no changes when all keys present
+- Verify error handling
+
+---
+
+### Step 1.4: Implement `has_cli_overrides()`
+
+**Location**: `src/config.c`
+
+**Purpose**: Check if any CLI overrides are present
+
+**Function Signature**:
+```c
+bool has_cli_overrides(const cli_options_t* cli_options);
+```
+
+**Implementation Details**:
+```c
+bool has_cli_overrides(const cli_options_t* cli_options) {
+    if (!cli_options) {
+        return false;
+    }
+
+    return (cli_options->port_override > 0 ||
+            cli_options->admin_pubkey_override[0] != '\0' ||
+            cli_options->relay_privkey_override[0] != '\0');
+}
+```
+
+**Testing**:
+- Verify returns true when any override present
+- Verify returns false when no overrides
+- Verify NULL safety
+
+---
+
+## 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);
+
+// 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);
+
+// Helper function to check for CLI overrides
+bool has_cli_overrides(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()) {
+    first_time_startup_sequence(&cli_options);
+    init_database(g_database_path);
+    
+    // Current incremental approach
+    populate_default_config_values();
+    if (cli_options.port_override > 0) {
+        char port_str[16];
+        snprintf(port_str, sizeof(port_str), "%d", cli_options.port_override);
+        update_config_in_table("relay_port", port_str);
+    }
+    add_pubkeys_to_config_table();
+    
+    store_relay_private_key(relay_privkey);
+    refresh_unified_cache_from_table();
+}
+```
+
+**New Code**:
+```c
+if (is_first_time_startup()) {
+    // 1. Generate keys and set database path
+    first_time_startup_sequence(&cli_options);
+    
+    // 2. Create database with schema
+    init_database(g_database_path);
+    
+    // 3. Populate ALL config values atomically (defaults + pubkeys)
+    if (populate_all_config_values_atomic(&cli_options) != 0) {
+        DEBUG_ERROR("Failed to populate config values");
+        return EXIT_FAILURE;
+    }
+    
+    // 4. Apply CLI overrides atomically (separate transaction)
+    if (apply_cli_overrides_atomic(&cli_options) != 0) {
+        DEBUG_ERROR("Failed to apply CLI overrides");
+        return EXIT_FAILURE;
+    }
+    
+    // 5. Store relay private key securely
+    store_relay_private_key(relay_privkey);
+    
+    // 6. Load complete config into cache
+    refresh_unified_cache_from_table();
+}
+```
+
+**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 {
+    char** existing_files = find_existing_db_files();
+    char* relay_pubkey = extract_pubkey_from_filename(existing_files[0]);
+    startup_existing_relay(relay_pubkey);
+    
+    init_database(g_database_path);
+    
+    // Current approach - unclear when overrides applied
+    populate_default_config_values();
+    if (cli_options.port_override > 0) {
+        // ... override logic ...
+    }
+    
+    refresh_unified_cache_from_table();
+}
+```
+
+**New Code**:
+```c
+else {
+    // 1. Discover existing database
+    char** existing_files = find_existing_db_files();
+    if (!existing_files || !existing_files[0]) {
+        DEBUG_ERROR("No existing database files found");
+        return EXIT_FAILURE;
+    }
+    
+    char* relay_pubkey = extract_pubkey_from_filename(existing_files[0]);
+    startup_existing_relay(relay_pubkey);
+    
+    // 2. Open existing database
+    init_database(g_database_path);
+    
+    // 3. Validate config table completeness (populate missing keys)
+    if (validate_config_table_completeness() != 0) {
+        DEBUG_ERROR("Failed to validate config table");
+        return EXIT_FAILURE;
+    }
+    
+    // 4. Apply CLI overrides if present (separate transaction)
+    if (has_cli_overrides(&cli_options)) {
+        if (apply_cli_overrides_atomic(&cli_options) != 0) {
+            DEBUG_ERROR("Failed to apply CLI overrides");
+            return EXIT_FAILURE;
+        }
+    }
+    
+    // 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 1: Core Functions
+- Day 1-2: Implement `populate_all_config_values_atomic()`
+- Day 3-4: Implement `apply_cli_overrides_atomic()`
+- Day 5: Implement `validate_config_table_completeness()` and `has_cli_overrides()`
+
+### Week 2: Integration
+- Day 1-2: Update main.c startup flow
+- 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
+```

+
+## Quick Start
+
+### 1. Build and Start
+```bash
+# Clone and build
+git clone <repository-url>
+cd c-relay
+git submodule update --init --recursive
+make
+
+# Start relay (zero configuration needed)
+./build/c_relay_x86
+```
+
+### 2. First Startup - Save Keys
+The relay will display admin keys on first startup:
+
+```
+=================================================================
+IMPORTANT: SAVE THIS ADMIN PRIVATE KEY SECURELY!
+=================================================================
+Admin Private Key: a018ecc259ff296ef7aaca6cdccbc52cf28104ac7a1f14c27b0b8232e5025ddc
+Admin Public Key:  68394d08ab87f936a42ff2deb15a84fbdfbe0996ee0eb20cda064aae673285d1
+=================================================================
+```
+
+⚠️ **CRITICAL**: Save the admin private key - it's needed for configuration updates and only shown once!
+
+### 3. Connect Clients
+Your relay is now available at:
+- **WebSocket**: `ws://localhost:8888`
+- **NIP-11 Info**: `http://localhost:8888` (with `Accept: application/nostr+json` header)
+- **Web Admin Interface**: `http://localhost:8888/api/` (serves embedded admin interface)
+
+## Installation
+
+### System Requirements
+- **Operating System**: Linux, macOS, or Windows (WSL)
+- **RAM**: Minimum 512MB, recommended 2GB+
+- **Disk**: 100MB for binary + database storage (grows with events)
+- **Network**: Port 8888 (configurable via events)
+
+### Dependencies
+Install required libraries:
+
+**Ubuntu/Debian:**
+```bash
+sudo apt update
+sudo apt install build-essential git sqlite3 libsqlite3-dev libwebsockets-dev libssl-dev libsecp256k1-dev libcurl4-openssl-dev zlib1g-dev
+```
+
+**CentOS/RHEL:**

+```
+
+### Production Deployment
+
+#### SystemD Service (Recommended)
+```bash
+# Install as system service
+sudo systemd/install-service.sh
+
+# Start service
+sudo systemctl start c-relay
+
+# Enable auto-start
+sudo systemctl enable c-relay
+
+# Check status
+sudo systemctl status c-relay
+```
+
+#### Manual Deployment
+```bash
+# Create dedicated user
+sudo useradd --system --home-dir /opt/c-relay --shell /bin/false c-relay
+
+# Install binary
+sudo mkdir -p /opt/c-relay
+sudo cp build/c_relay_x86 /opt/c-relay/
+sudo chown -R c-relay:c-relay /opt/c-relay
+
+# Run as service user
+sudo -u c-relay /opt/c-relay/c_relay_x86
+```
+
+## Configuration Management
+
+### Event-Based Configuration System
+
+Unlike traditional relays that use config files, this relay stores all configuration as **kind 33334 Nostr events** in the database. This provides:
+
+- **Real-time updates**: Changes applied instantly without restart
+- **Cryptographic security**: All config changes must be signed by admin
+- **Audit trail**: Complete history of configuration changes
+- **No file management**: No config files to manage or version control
+
+### First-Time Configuration
+
+On first startup, the relay:
+
+1. **Generates keypairs**: Creates cryptographically secure admin and relay keys
+2. **Creates database**: `<relay_pubkey>.nrdb` file with optimized schema
+3. **Stores default config**: Creates initial kind 33334 event with sensible defaults
+4. **Displays admin key**: Shows admin private key once for you to save
+
+### Updating Configuration
+
+To change relay configuration, create and send a signed kind 33334 event:
+
+#### Using nostrtool (recommended)
+```bash
+# Install nostrtool
+npm install -g nostrtool
+
+# Update relay description
+nostrtool event \
+  --kind 33334 \
+  --content "C Nostr Relay Configuration" \
+  --tag d <relay_pubkey> \
+  --tag relay_description "My Production Relay" \
+  --tag max_subscriptions_per_client 50 \
+  --private-key <admin_private_key> \
+  | nostrtool send ws://localhost:8888
+```
+
+#### Manual Event Creation
+```json
+{
+  "kind": 33334,
+  "content": "C Nostr Relay Configuration",
+  "tags": [
+    ["d", "<relay_pubkey>"],
+    ["relay_description", "My Production Relay"],
+    ["max_subscriptions_per_client", "50"],
+    ["pow_min_difficulty", "20"]
+  ],
+  "created_at": 1699123456,
+  "pubkey": "<admin_pubkey>",
+  "id": "<computed_event_id>",
+  "sig": "<signature>"
+}
+```
+
+Send this to your relay via WebSocket, and changes are applied immediately.

+## 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
+
+## Administration
+
+### Viewing Current Configuration
+```bash
+# Find your database
+ls -la *.nrdb
+
+# View configuration events
+sqlite3 <relay_pubkey>.nrdb "SELECT created_at, tags FROM events WHERE kind = 33334 ORDER BY created_at DESC LIMIT 1;"
+
+# View all configuration history
+sqlite3 <relay_pubkey>.nrdb "SELECT datetime(created_at, 'unixepoch') as date, tags FROM events WHERE kind = 33334 ORDER BY created_at DESC;"
+```
+
+### Admin Key Management
+
+#### Backup Admin Keys
+```bash
+# Create secure backup
+echo "Admin Private Key: <your_admin_key>" > admin_keys_backup_$(date +%Y%m%d).txt
+chmod 600 admin_keys_backup_*.txt
+
+# Store in secure location (password manager, encrypted drive, etc.)
+```
+
+#### Key Recovery
+If you lose your admin private key:
+
+1. **Stop the relay**: `pkill c_relay` or `sudo systemctl stop c-relay`
+2. **Backup events**: `cp <relay_pubkey>.nrdb backup_$(date +%Y%m%d).nrdb`
+3. **Remove database**: `rm <relay_pubkey>.nrdb*`
+4. **Restart relay**: This creates new database with new keys
+5. **⚠️ Note**: All stored events and configuration history will be lost
+
+### Security Best Practices
+
+#### Admin Key Security
+- **Never share** the admin private key
+- **Store securely** in password manager or encrypted storage
+- **Backup safely** to multiple secure locations
+- **Monitor** configuration changes in logs
+
+#### Network Security
+```bash
+# Restrict access with firewall
+sudo ufw allow 8888/tcp
+
+# Use reverse proxy for HTTPS (recommended)
+# Configure nginx/apache to proxy to ws://localhost:8888
+```
+
+#### Database Security
+```bash
+# Secure database file permissions
+chmod 600 <relay_pubkey>.nrdb
+chown c-relay:c-relay <relay_pubkey>.nrdb
+
+# Regular backups
+cp <relay_pubkey>.nrdb backup/relay_backup_$(date +%Y%m%d_%H%M%S).nrdb
+```
+
+## Monitoring
+
+### Service Status
+```bash
+# Check if relay is running
+ps aux | grep c_relay
+
+# SystemD status
+sudo systemctl status c-relay
+
+# Network connections
+netstat -tln | grep 8888
+sudo ss -tlpn | grep 8888
+```
+
+### Log Monitoring
+```bash
+# Real-time logs (systemd)
+sudo journalctl -u c-relay -f
+
+# Recent logs
+sudo journalctl -u c-relay --since "1 hour ago"
+
+# Error logs only
+sudo journalctl -u c-relay -p err
+
+# Configuration changes
+sudo journalctl -u c-relay | grep "Configuration updated via kind 33334"
+```
+
+### Database Analytics
+```bash
+# Connect to database
+sqlite3 <relay_pubkey>.nrdb
+
+# Event statistics
+SELECT event_type, COUNT(*) as count FROM events GROUP BY event_type;
+
+# Recent activity
+SELECT datetime(created_at, 'unixepoch') as date, kind, LENGTH(content) as content_size 
+FROM events 
+ORDER BY created_at DESC 
+LIMIT 10;
+
+# Subscription analytics (if logging enabled)
+SELECT * FROM subscription_analytics ORDER BY date DESC LIMIT 7;
+
+# Configuration changes
+SELECT datetime(created_at, 'unixepoch') as date, tags 
+FROM configuration_events 
+ORDER BY created_at DESC;
+```
+
+### Performance Monitoring
+```bash
+# Database size
+du -sh <relay_pubkey>.nrdb*
+
+# Memory usage
+ps aux | grep c_relay | awk '{print $6}' # RSS memory in KB
+
+# Connection count (approximate)
+netstat -an | grep :8888 | grep ESTABLISHED | wc -l
+
+# System resources
+top -p $(pgrep c_relay)
+```
+
+## Troubleshooting
+
+### Common Issues
+
+#### Relay Won't Start
+```bash
+# Check port availability
+netstat -tln | grep 8888
+# If port in use, find process: sudo lsof -i :8888
+
+# Check binary permissions
+ls -la build/c_relay_x86
+chmod +x build/c_relay_x86
+
+# Check dependencies
+ldd build/c_relay_x86
+```
+
+#### Configuration Not Updating
+1. **Verify signature**: Ensure event is properly signed with admin private key
+2. **Check admin pubkey**: Must match the pubkey from first startup
+3. **Validate event structure**: Use `nostrtool validate` or similar
+4. **Check logs**: Look for validation errors in relay logs
+5. **Test WebSocket**: Ensure WebSocket connection is active
+
+```bash
+# Test WebSocket connection
+wscat -c ws://localhost:8888
+
+# Send test message
+{"id":"test","method":"REQ","params":["test",{}]}
+```
+
+#### Database Issues
+```bash
+# Check database integrity
+sqlite3 <relay_pubkey>.nrdb "PRAGMA integrity_check;"
+
+# Check schema version
+sqlite3 <relay_pubkey>.nrdb "SELECT * FROM schema_info WHERE key = 'version';"
+
+# View database size and stats
+sqlite3 <relay_pubkey>.nrdb "PRAGMA page_size; PRAGMA page_count;"
+```
+
+#### Performance Issues
+```bash
+# Analyze slow queries (if any)
+sqlite3 <relay_pubkey>.nrdb "PRAGMA compile_options;"
+
+# Check database optimization
+sqlite3 <relay_pubkey>.nrdb "PRAGMA optimize;"
+
+# Monitor system resources
+iostat 1 5  # I/O statistics
+free -h     # Memory usage
+```
+
+### Recovery Procedures
+
+#### Corrupted Database Recovery
+```bash
+# Attempt repair
+sqlite3 <relay_pubkey>.nrdb ".recover" > recovered.sql
+sqlite3 recovered.nrdb < recovered.sql
+
+# If repair fails, start fresh (loses all events)
+mv <relay_pubkey>.nrdb <relay_pubkey>.nrdb.corrupted
+./build/c_relay_x86  # Creates new database
+```
+
+#### Lost Configuration Recovery
+If configuration is lost but database is intact:
+
+1. **Find old config**: `sqlite3 <relay_pubkey>.nrdb "SELECT * FROM configuration_events;"`
+2. **Create new config event**: Use last known good configuration
+3. **Sign and send**: Update with current timestamp and new signature
+
+#### Emergency Restart
+```bash
+# Quick restart with clean state
+sudo systemctl stop c-relay
+mv <relay_pubkey>.nrdb <relay_pubkey>.nrdb.backup
+sudo systemctl start c-relay
+
+# Check logs for new admin keys
+sudo journalctl -u c-relay --since "5 minutes ago" | grep "Admin Private Key"
+```
+
+## Advanced Usage
+
+### Custom Event Handlers
+The relay supports custom handling for different event types. Configuration changes trigger:
+
+- **Subscription Manager Updates**: When client limits change
+- **PoW System Reinitialization**: When PoW settings change
+- **Expiration System Updates**: When NIP-40 settings change
+- **Relay Info Updates**: When NIP-11 information changes
+
+### API Integration
+```javascript
+// Connect and send configuration update
+const ws = new WebSocket('ws://localhost:8888');
+
+ws.on('open', function() {
+  const configEvent = {
+    kind: 33334,
+    content: "Updated configuration",
+    tags: [
+      ["d", relayPubkey],
+      ["relay_description", "Updated via API"]
+    ],
+    created_at: Math.floor(Date.now() / 1000),
+    pubkey: adminPubkey,
+    // ... add id and sig
+  };
+  
+  ws.send(JSON.stringify(["EVENT", configEvent]));
+});
+```
+
+### Backup Strategies
+
+#### Automated Backup
+```bash
+#!/bin/bash
+# backup-relay.sh
+DATE=$(date +%Y%m%d_%H%M%S)
+DB_FILE=$(ls *.nrdb | head -1)
+BACKUP_DIR="/backup/c-relay"
+
+mkdir -p $BACKUP_DIR
+cp $DB_FILE $BACKUP_DIR/relay_backup_$DATE.nrdb
+gzip $BACKUP_DIR/relay_backup_$DATE.nrdb
+
+# Cleanup old backups (keep 30 days)
+find $BACKUP_DIR -name "relay_backup_*.nrdb.gz" -mtime +30 -delete
+```
+
+#### Configuration Export
+```bash
+# Export configuration events
+sqlite3 <relay_pubkey>.nrdb "SELECT json_object(
+  'kind', kind,
+  'content', content,
+  'tags', json(tags),
+  'created_at', created_at,
+  'pubkey', pubkey,
+  'sig', sig
+) FROM events WHERE kind = 33334 ORDER BY created_at;" > config_backup.json
+```
+
+### Migration Between Servers
+```bash
+# Source server
+tar czf relay_migration.tar.gz *.nrdb* relay.log
+
+# Target server  
+tar xzf relay_migration.tar.gz
+./build/c_relay_x86  # Will detect existing database and continue
+```

+# WebSocket Write Queue Design
+
+## Problem Statement
+
+The current partial write handling implementation uses a single buffer per session, which fails when multiple events need to be sent to the same client in rapid succession. This causes:
+
+1. First event gets partial write → queued successfully
+2. Second event tries to write → **FAILS** with "write already pending"
+3. Subsequent events fail similarly, causing data loss
+
+### Server Log Evidence
+```
+[WARN] WS_FRAME_PARTIAL: EVENT partial write, sub=1 sent=3210 expected=5333
+[TRACE] Queued partial write: len=2123
+[WARN] WS_FRAME_PARTIAL: EVENT partial write, sub=1 sent=3210 expected=5333
+[WARN] queue_websocket_write: write already pending, cannot queue new write
+[ERROR] Failed to queue partial EVENT write for sub=1
+```
+
+## Root Cause
+
+WebSocket frames must be sent **atomically** - you cannot interleave multiple frames. The current single-buffer approach correctly enforces this, but it rejects new writes instead of queuing them.
+
+## Solution: Write Queue Architecture
+
+### Design Principles
+
+1. **Frame Atomicity**: Complete one WebSocket frame before starting the next
+2. **Sequential Processing**: Process queued writes in FIFO order
+3. **Memory Safety**: Proper cleanup on connection close or errors
+4. **Thread Safety**: Protect queue operations with existing session lock
+
+### Data Structures
+
+#### Write Queue Node
+```c
+struct write_queue_node {
+    unsigned char* buffer;           // Buffer with LWS_PRE space
+    size_t total_len;                // Total length of data to write
+    size_t offset;                   // How much has been written so far
+    int write_type;                  // LWS_WRITE_TEXT, etc.
+    struct write_queue_node* next;   // Next node in queue
+};
+```
+
+#### Per-Session Write Queue
+```c
+struct per_session_data {
+    // ... existing fields ...
+    
+    // Write queue for handling multiple pending writes
+    struct write_queue_node* write_queue_head;  // First item to write
+    struct write_queue_node* write_queue_tail;  // Last item in queue
+    int write_queue_length;                     // Number of items in queue
+    int write_in_progress;                      // Flag: 1 if currently writing
+};
+```
+
+### Algorithm Flow
+
+#### 1. Enqueue Write (`queue_websocket_write`)
+
+```
+IF write_queue is empty AND no write in progress:
+    - Attempt immediate write with lws_write()
+    - IF complete:
+        - Return success
+    - ELSE (partial write):
+        - Create queue node with remaining data
+        - Add to queue
+        - Set write_in_progress flag
+        - Request LWS_CALLBACK_SERVER_WRITEABLE
+ELSE:
+    - Create queue node with full data
+    - Append to queue tail
+    - IF no write in progress:
+        - Request LWS_CALLBACK_SERVER_WRITEABLE
+```
+
+#### 2. Process Queue (`process_pending_write`)
+
+```
+WHILE write_queue is not empty:
+    - Get head node
+    - Calculate remaining data (total_len - offset)
+    - Attempt write with lws_write()
+    
+    IF write fails (< 0):
+        - Log error
+        - Remove and free head node
+        - Continue to next node
+    
+    ELSE IF partial write (< remaining):
+        - Update offset
+        - Request LWS_CALLBACK_SERVER_WRITEABLE
+        - Break (wait for next callback)
+    
+    ELSE (complete write):
+        - Remove and free head node
+        - Continue to next node
+
+IF queue is empty:
+    - Clear write_in_progress flag
+```
+
+#### 3. Cleanup (`LWS_CALLBACK_CLOSED`)
+
+```
+WHILE write_queue is not empty:
+    - Get head node
+    - Free buffer
+    - Free node
+    - Move to next
+Clear queue pointers
+```
+
+### Memory Management
+
+1. **Allocation**: Each queue node allocates buffer with `LWS_PRE + data_len`
+2. **Ownership**: Queue owns all buffers until write completes or connection closes
+3. **Deallocation**: Free buffer and node when:
+   - Write completes successfully
+   - Write fails with error
+   - Connection closes
+
+### Thread Safety
+
+- Use existing `pss->session_lock` to protect queue operations
+- Lock during:
+  - Enqueue operations
+  - Dequeue operations
+  - Queue traversal for cleanup
+
+### Performance Considerations
+
+1. **Queue Length Limit**: Implement max queue length (e.g., 100 items) to prevent memory exhaustion
+2. **Memory Pressure**: Monitor total queued bytes per session
+3. **Backpressure**: If queue exceeds limit, close connection with NOTICE
+
+### Error Handling
+
+1. **Allocation Failure**: Return error, log, send NOTICE to client
+2. **Write Failure**: Remove failed frame, continue with next
+3. **Queue Overflow**: Close connection with appropriate NOTICE
+
+## Implementation Plan
+
+### Phase 1: Data Structure Changes
+1. Add `write_queue_node` structure to `websockets.h`
+2. Update `per_session_data` with queue fields
+3. Remove old single-buffer fields
+
+### Phase 2: Queue Operations
+1. Implement `enqueue_write()` helper
+2. Implement `dequeue_write()` helper
+3. Update `queue_websocket_write()` to use queue
+4. Update `process_pending_write()` to process queue
+
+### Phase 3: Integration
+1. Update all `lws_write()` call sites
+2. Update `LWS_CALLBACK_CLOSED` cleanup
+3. Add queue length monitoring
+
+### Phase 4: Testing
+1. Test with rapid multiple events to same client
+2. Test with large events (>4KB)
+3. Test under load with concurrent connections
+4. Verify no "Invalid frame header" errors
+
+## Expected Outcomes
+
+1. **No More Rejections**: All writes queued successfully
+2. **Frame Integrity**: Complete frames sent atomically
+3. **Memory Safety**: Proper cleanup on all paths
+4. **Performance**: Minimal overhead for queue management
+
+## Metrics to Monitor
+
+1. Average queue length per session
+2. Maximum queue length observed
+3. Queue overflow events (if limit implemented)
+4. Write completion rate
+5. Partial write frequency
+
+## Alternative Approaches Considered
+
+### 1. Larger Single Buffer
+**Rejected**: Doesn't solve the fundamental problem of multiple concurrent writes
+
+### 2. Immediate Write Retry
+**Rejected**: Could cause busy-waiting and CPU waste
+
+### 3. Drop Frames on Conflict
+**Rejected**: Violates reliability requirements

+# Deployment Examples
+
+This directory contains practical deployment examples and scripts for the C Nostr Relay with event-based configuration.
+
+## Directory Structure
+
+```
+examples/deployment/
+├── README.md                 # This file
+├── simple-vps/              # Basic VPS deployment
+├── nginx-proxy/             # Nginx reverse proxy configurations
+├── monitoring/              # Monitoring and alerting examples
+└── backup/                  # Backup and recovery scripts
+```
+
+## Quick Start Examples
+
+### 1. Simple VPS Deployment
+For a basic Ubuntu VPS deployment:
+```bash
+cd examples/deployment/simple-vps
+chmod +x deploy.sh
+sudo ./deploy.sh
+```
+
+### 2. SSL Proxy Setup
+For nginx reverse proxy with SSL:
+```bash
+cd examples/deployment/nginx-proxy
+chmod +x setup-ssl-proxy.sh
+sudo ./setup-ssl-proxy.sh -d relay.example.com -e admin@example.com
+```
+
+### 3. Monitoring Setup
+For continuous monitoring:
+```bash
+cd examples/deployment/monitoring
+chmod +x monitor-relay.sh
+sudo ./monitor-relay.sh -c -e admin@example.com
+```
+
+### 4. Backup Setup
+For automated backups:
+```bash
+cd examples/deployment/backup
+chmod +x backup-relay.sh
+sudo ./backup-relay.sh -s my-backup-bucket -e admin@example.com
+```
+
+## Configuration Examples
+
+All examples assume the event-based configuration system where:
+- No config files are needed
+- Configuration is stored as kind 33334 events in the database
+- Admin keys are generated on first startup
+- Database naming uses relay pubkey (`<relay_pubkey>.nrdb`)
+
+## Security Notes
+
+- **Save Admin Keys**: All deployment examples emphasize capturing the admin private key on first startup
+- **Firewall Configuration**: Examples include proper firewall rules
+- **SSL/TLS**: Production examples include HTTPS configuration
+- **User Isolation**: Service runs as dedicated `c-relay` system user
+
+## Support
+
+For detailed documentation, see:
+- [`docs/deployment_guide.md`](../../docs/deployment_guide.md) - Comprehensive deployment guide
+- [`docs/user_guide.md`](../../docs/user_guide.md) - User guide

+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 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([

+  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';

+
+## 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.

+## Upgrading
+
+Upgrade from `micro-aes-gcm` package is simple:
+
+```js
+// prepare
+const key = Uint8Array.from([
+  64, 196, 127, 247, 172, 2, 34, 159, 6, 241, 30, 174, 183, 229, 41, 114, 253, 122, 119, 168, 177,
+  243, 155, 236, 164, 159, 98, 72, 162, 243, 224, 195,
+]);
+const message = 'Hello world';
+
+// previous
+import * as aes from 'micro-aes-gcm';
+const ciphertext = await aes.encrypt(key, aes.utils.utf8ToBytes(message));
+const plaintext = await aes.decrypt(key, ciphertext);
+console.log(aes.utils.bytesToUtf8(plaintext) === message);
+
+// became =>
+
+import { gcm } from '@noble/ciphers/aes';
+import { bytesToUtf8, utf8ToBytes } from '@noble/ciphers/utils';
+import { managedNonce } from '@noble/ciphers/webcrypto';
+const aes = managedNonce(gcm)(key);
+const ciphertext = aes.encrypt(utf8ToBytes(message));
+const plaintext = aes.decrypt(key, ciphertext);
+console.log(bytesToUtf8(plaintext) === message);

+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
