+### 8. Unreachable Code Removal
+
+**Problem**: Stress tests with unreachable code after `markTestSkipped()`
+**Location**: `tests/Performance/StressTest.php`
+**Solution**: Removed unreachable code and created separate manual test script
+
+```php
+// Before: Unreachable code after markTestSkipped()
+public function testHighConcurrentRequests(): void
+{
+    self::markTestSkipped('Stress tests should be run manually');
+    
+    // Hundreds of lines of unreachable code...
+    $concurrentRequests = 100;
+    // ... more unreachable implementation
+}
+
+// After: Clean test method
+public function testHighConcurrentRequests(): void
+{
+    self::markTestSkipped('Stress tests should be run manually');
+}
+```
+
+**Solution**: Created `scripts/stress-test.php` with all stress test implementations that can be run manually:
+```bash
+php scripts/stress-test.php
+```
+
 ## Future Recommendations
 
 1. **Continuous Quality Monitoring**: Run regular code quality checks
 2. **Automated Reviews**: Integrate AI-powered code review in CI/CD
 3. **Test Coverage**: Maintain high test coverage with meaningful assertions
 4. **Documentation**: Keep implementation guides updated with learnings
+5. **Separate Manual Tests**: Keep manual test code in scripts, not in unreachable PHPUnit methods

+### Manual Stress Testing
+
+For comprehensive stress testing, use the dedicated manual script:
+
+```bash
+# Run all stress tests
+php scripts/stress-test.php
+
+# The script includes:
+# - High concurrent requests testing
+# - Memory usage monitoring under load
+# - CPU intensive workload testing
+# - Large response handling
+# - Error recovery validation
 ```
