v0.7.10 - Fixed api errors in accepting : in subscriptions

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

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

+## 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.

+# 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

+## Best Practices
+
+1. **Always verify** the binary is truly static before deployment
+2. **Test on multiple distributions** to ensure portability
+3. **Keep Docker images updated** for security patches
+4. **Document the build date** and commit hash for reproducibility
+5. **Store binaries** with architecture in filename (e.g., `_x86_64`, `_arm64`)

+# 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.

+# Why MUSL Compilation Fails: Technical Explanation
+
+## The Core Problem
+
+**You cannot mix glibc headers/libraries with MUSL's C library.** They are fundamentally incompatible at the ABI (Application Binary Interface) level.
+
+## What Happens When We Try
+
+```bash
+musl-gcc -I/usr/include src/main.c -lwebsockets
+```
+
+### Step-by-Step Breakdown:
+
+1. **musl-gcc includes `<libwebsockets.h>`** from `/usr/include/libwebsockets.h`
+
+2. **libwebsockets.h includes standard C headers:**
+   ```c
+   #include <string.h>
+   #include <stdlib.h>
+   #include <stdio.h>
+   ```
+
+3. **The system provides glibc's version of these headers** (from `/usr/include/`)
+
+4. **glibc's `<string.h>` includes glibc-specific internal headers:**
+   ```c
+   #include <bits/libc-header-start.h>
+   #include <bits/types.h>
+   ```
+
+5. **MUSL doesn't have these `bits/` headers** - it has a completely different structure:
+   - MUSL uses `/usr/include/x86_64-linux-musl/` for its headers
+   - MUSL's headers are simpler and don't use the `bits/` subdirectory structure
+
+6. **Compilation fails** with:
+   ```
+   fatal error: bits/libc-header-start.h: No such file or directory
+   ```
+
+## Why This Is Fundamental
+
+### Different C Library Implementations
+
+**glibc (GNU C Library):**
+- Complex, feature-rich implementation
+- Uses `bits/` subdirectories for platform-specific code
+- Larger binary size
+- More system-specific optimizations
+
+**MUSL:**
+- Minimal, clean implementation
+- Simpler header structure
+- Smaller binary size
+- Designed for static linking and portability
+
+### ABI Incompatibility
+
+Even if headers compiled, the **Application Binary Interface (ABI)** is different:
+- Function calling conventions may differ
+- Structure layouts may differ
+- System call wrappers are implemented differently
+- Thread-local storage mechanisms differ
+
+## The Solution: Build Everything with MUSL
+
+To create a true MUSL static binary, you must:
+
+### 1. Build libwebsockets with musl-gcc
+
+```bash
+git clone https://github.com/warmcat/libwebsockets.git
+cd libwebsockets
+mkdir build && cd build
+cmake .. \
+    -DCMAKE_C_COMPILER=musl-gcc \
+    -DCMAKE_BUILD_TYPE=Release \
+    -DLWS_WITH_STATIC=ON \
+    -DLWS_WITH_SHARED=OFF \
+    -DLWS_WITHOUT_TESTAPPS=ON
+make
+```
+
+### 2. Build OpenSSL with MUSL
+
+```bash
+wget https://www.openssl.org/source/openssl-3.0.0.tar.gz
+tar xzf openssl-3.0.0.tar.gz
+cd openssl-3.0.0
+CC=musl-gcc ./config no-shared --prefix=/opt/musl-openssl
+make && make install
+```
+
+### 3. Build all other dependencies
+
+- zlib with musl-gcc
+- libsecp256k1 with musl-gcc  
+- libcurl with musl-gcc (which itself needs OpenSSL built with MUSL)
+
+### 4. Build c-relay with all MUSL libraries
+
+```bash
+musl-gcc -static \
+    -I/opt/musl-libwebsockets/include \
+    -I/opt/musl-openssl/include \
+    src/*.c \
+    -L/opt/musl-libwebsockets/lib -lwebsockets \
+    -L/opt/musl-openssl/lib -lssl -lcrypto \
+    ...
+```
+
+## Why We Use glibc Static Instead
+
+Building the entire dependency chain with MUSL is:
+- **Time-consuming**: Hours to build all dependencies
+- **Complex**: Each library has its own build quirks
+- **Maintenance burden**: Must rebuild when dependencies update
+- **Unnecessary for most use cases**: glibc static binaries work fine
+
+### glibc Static Binary Advantages:
+
+✅ **Still fully static** - no runtime dependencies  
+✅ **Works on virtually all Linux distributions**  
+✅ **Much faster to build** - uses system libraries  
+✅ **Easier to maintain** - no custom dependency builds  
+✅ **Same practical portability** for modern Linux systems
+
+### glibc Static Binary Limitations:
+
+⚠️ **Slightly larger** than MUSL (glibc is bigger)  
+⚠️ **May not work on very old systems** (ancient glibc versions)  
+⚠️ **Not as universally portable** as MUSL (but close enough)
+
+## Conclusion
+
+**MUSL compilation fails because system libraries are compiled with glibc, and you cannot mix glibc and MUSL.**
+
+The current approach (glibc static binary) is the pragmatic solution that provides excellent portability without the complexity of building an entire MUSL toolchain.
+
+If true MUSL binaries are needed in the future, the solution is to use Alpine Linux (which uses MUSL natively) in a Docker container, where all system libraries are already MUSL-compiled.

+### Relay Setup
+Before running tests, ensure the C-Relay is running:
+
+```bash
+# Build and start the relay
+./make_and_restart_relay.sh
+
+# Verify it's running
+ps aux | grep c_relay
+curl -H "Accept: application/nostr+json" http://localhost:8888
+```
+
+## Running Tests
+
+### Quick Start
+1. Start the relay:
+   ```bash
+   ./make_and_restart_relay.sh
+   ```
+
+2. Run all tests:
+   ```bash
+   ./tests/run_all_tests.sh
+   ```
+
+### Individual Test Suites
+Run specific test suites for targeted testing:
+
+```bash
+# Security tests
+./tests/sql_injection_tests.sh
+./tests/memory_corruption_tests.sh
+./tests/input_validation_tests.sh
+
+# Performance tests
+./tests/load_tests.sh
+
+# Existing tests
+./tests/filter_validation_test.sh
+./tests/subscription_limits.sh
+./tests/subscription_validation.sh
+```
+
+### NIP Protocol Tests
+Run the existing NIP compliance tests:
+
+```bash
+# Run all NIP tests
+./tests/run_nip_tests.sh
+
+# Or run individual NIP tests
+./tests/1_nip_test.sh
+./tests/11_nip_information.sh
+./tests/42_nip_test.sh
+# ... etc
+```
+
+## Test Results and Reporting
+
+### Master Test Runner Output
+The master test runner (`run_all_tests.sh`) generates:
+
+1. **Console Output**: Real-time test progress and results
+2. **Log File**: Detailed execution log (`test_results_YYYYMMDD_HHMMSS.log`)
+3. **HTML Report**: Comprehensive web report (`test_report_YYYYMMDD_HHMMSS.html`)
+
+### Individual Test Suite Output
+Each test suite provides:
+- Test-by-test results with PASS/FAIL status
+- Summary statistics (passed/failed/total tests)
+- Detailed error information for failures
+
+### Interpreting Results
+
+#### Security Tests
+- **PASS**: No vulnerabilities detected
+- **FAIL**: Potential security issues found
+- **UNCERTAIN**: Test inconclusive (may need manual verification)
+
+#### Performance Tests
+- **Connection Success Rate**: >95% = Excellent, >80% = Good, <80% = Poor
+- **Resource Usage**: Monitor CPU/memory during load tests
+- **Relay Responsiveness**: Must remain responsive after all tests
+
+## Test Configuration
+
+### Environment Variables
+Customize test behavior with environment variables:
+
+```bash
+# Relay connection settings
+export RELAY_HOST="127.0.0.1"
+export RELAY_PORT="8888"
+
+# Test parameters
+export TEST_TIMEOUT=10
+export CONCURRENT_CONNECTIONS=50
+export MESSAGES_PER_SECOND=100
+```
+
+### Test Customization
+Modify test parameters within individual test scripts:
+
+- `RELAY_HOST` / `RELAY_PORT`: Relay connection details
+- `TEST_TIMEOUT`: Individual test timeout (seconds)
+- `TOTAL_TESTS`: Number of test iterations
+- Load test parameters in `load_tests.sh`
+
+## Troubleshooting
+
+### Common Issues
+
+#### "Could not connect to relay"
+- Ensure relay is running: `./make_and_restart_relay.sh`
+- Check port availability: `netstat -tln | grep 8888`
+- Verify relay process: `ps aux | grep c_relay`
+
+#### "websocat: command not found"
+- Install websocat: `sudo apt-get install websocat`
+- Or download from: https://github.com/vi/websocat/releases
+
+#### Tests timing out
+- Increase `TEST_TIMEOUT` value
+- Check system resources (CPU/memory)
+- Reduce concurrent connections in load tests
+
+#### High failure rates in load tests
+- Reduce `CONCURRENT_CONNECTIONS`
+- Check system ulimits: `ulimit -n`
+- Monitor system resources during testing
+
+### Debug Mode
+Enable verbose output for debugging:
+
+```bash
+# Set debug environment variable
+export DEBUG=1
+
+# Run tests with verbose output
+./tests/run_all_tests.sh
+```
+
+## Security Testing Methodology
+
+### SQL Injection Testing
+- Tests all filter types (authors, IDs, kinds, search, tags)
+- Uses comprehensive payload library
+- Validates parameterized query protection
+- Tests edge cases and boundary conditions
+
+### Memory Safety Testing
+- Buffer overflow detection
+- Use-after-free prevention
+- Concurrent access validation
+- Malformed input handling
+
+### Input Validation Testing
+- Boundary condition testing
+- Type validation
+- Length limit enforcement
+- Malformed data rejection
+
+## Performance Benchmarking
+
+### Load Testing Scenarios
+1. **Light Load**: Basic functionality validation
+2. **Medium Load**: Moderate stress testing
+3. **Heavy Load**: High concurrency validation
+4. **Stress Test**: Breaking point identification
+
+### Metrics Collected
+- Connection success rate
+- Message throughput
+- Response times
+- Resource utilization (CPU, memory)
+- Relay stability under load
+
+## Integration with CI/CD
+
+### Automated Testing
+Integrate with CI/CD pipelines:
+
+```yaml
+# Example GitHub Actions workflow
+- name: Run C-Relay Tests
+  run: |
+    ./make_and_restart_relay.sh
+    ./tests/run_all_tests.sh
+```
+
+### Test Result Processing
+Parse test results for automated reporting:
+
+```bash
+# Extract test summary
+grep "Total tests:" test_results_*.log
+grep "Passed:" test_results_*.log
+grep "Failed:" test_results_*.log
+```
+
+## Contributing
+
+### Adding New Tests
+1. Create new test script in `tests/` directory
+2. Follow existing naming conventions
+3. Add to master test runner in `run_all_tests.sh`
+4. Update this documentation
+
+### Test Script Template
+```bash
+#!/bin/bash
+# Test suite description
+
+set -e
+
+# Configuration
+RELAY_HOST="${RELAY_HOST:-127.0.0.1}"
+RELAY_PORT="${RELAY_PORT:-8888}"
+
+# Test implementation here
+
+echo "Test suite completed successfully"
+```
+
+## Security Considerations
+
+### Test Environment
+- Run tests in isolated environment
+- Use test relay instance (not production)
+- Monitor system resources during testing
+- Clean up test data after completion
+
+### Sensitive Data
+- Tests use synthetic data only
+- No real user data in test payloads
+- Safe for production system testing
+
+## Support and Issues
+
+### Reporting Test Failures
+When reporting test failures, include:
+1. Test suite and specific test that failed
+2. Full error output
+3. System information (OS, relay version)
+4. Relay configuration
+5. Test environment details
+
+### Getting Help
+- Check existing issues in the project repository
+- Review test logs for detailed error information
+- Validate relay setup and configuration
+- Test with minimal configuration to isolate issues
